DETAILED DESCRIPTION OF THE EMBODIMENTS

[0042] The embodiments of the present application will be described clearly and completely as follows in conjunction with the drawings in the embodiments of the present application. It is apparent that the described embodiments are only some of the embodiments according to the present application, rather than all the embodiments.

[0043] The core of the present application is to provide a zipper lower stop and a zipper having the zipper lower stop, which is convenient to use.

[0044] In a first embodiment of a zipper lower stop provided according to the present application, referring to FIGS. 1 to 8, the zipper lower stop includes a lower stop plane member 4 and a lower stop bottom member 5.

[0045] As shown in FIG. 6, the lower stop plane member 4 includes a plane member cylinder 4.3, and a hook 4.4 protrudes from an outer peripheral surface of the plane member cylinder 4.3. The hook 4.4 includes a hook-shaped structure formed by a butt-joint of a guide rod portion 4.4b and a hook protrusion 4.4a, where the hook protrusion 4.4a is located at bottom of the hook 4.4 in an axial direction. In this embodiment, the axial direction, circumferential direction and radial direction are based on the axial direction, circumferential direction and radial direction of the plane member cylinder 4.3, and two ends in the axial direction are upper end and lower end respectively. The axial direction is perpendicular to a moving direction of a slider 2 when the lower stop plane member 4 being mounted on cloth tape 1.

[0046] As shown in FIG. 7, a main groove 5.3 is formed in the middle of the lower stop bottom member 5. A bottom member guide protrusion 5.4 and a bottom member limiting protrusion 5.9 are formed on an inner peripheral surface of the main groove 5.3. The bottom member guide protrusion 5.4 and the bottom member limiting protrusion 5.9 are sequentially arranged in the circumferential direction with a guide channel 5.11 formed between them. In one embodiment, the lower stop bottom member 5 includes a bottom member bottom board 5.2 and a bottom member ring board 5.13 fixed above the bottom member bottom board 5.2 in the axial direction. The main groove 5.3 is located in a space surrounded by the bottom member ring board 5.13 above the bottom member bottom board 5.2.

[0047] In a process of assembling the lower stop plane member 4 to the lower stop bottom member 5, the plane member cylinder 4.3 enters the main groove 5.3 axially downwards, and the hook 4.4 enters the guide channel 5.11 axially downwards. At the same time, the guide rod portion 4.4b and the bottom member guide protrusion 5.4 fit in the circumferential direction and an oblique guiding is formed, to push the lower stop plane member 4 to rotate around a center line of the plane member cylinder 4.3 relative to the lower stop bottom member 5. The plane member cylinder 4.3 is locked with the main groove 5.3, and the lower stop plane member 4 and the lower stop bottom member 5 can be aligned and limited in the radial direction, and the lower stop plane member 4 and the lower stop bottom member 5 are prevented from moving relative to each other in the radial direction. After the lower stop plane member 4 moves axially until a lower stop plane board abuts against the lower stop bottom member 5 in the axial direction, the lower stop plane member 4 continues to rotate, enabling the hook protrusion 4.4a to extend into the limiting groove 5.12 of the bottom member limiting protrusion 5.9, and to prevent the lower stop plane member 4 from being separated from the lower stop bottom member 5 in the axial direction.

[0048] In this embodiment, when the zipper lower stop is assembled, the lower stop plane member 4 and the lower stop bottom member 5 are axially aligned first, and then rotate and move axially with each other until they axially abut against each other. Subsequently, the hook 4.4 is stuck with the bottom member limiting protrusion 5.9 through the rotation of the lower stop plane member 4, achieving an axial limiting. Through the whole process, a movement along the moving direction of the slider 2 is not necessary, which can reduce a step of manually determining whether the lower stop plane member 4 and the lower stop bottom member 5 are properly connected with each other, making it easier to use and facilitating a quick and convenient closure of the zipper.

[0049] Further, as shown in FIGS. 6 and 7, the guide rod portion 4.4b gradually extends downward along the axial direction and obliquely in the circumferential direction. A circumferential end surface of the bottom member guide protrusion 5.4 close to the bottom member limiting protrusion 5.9 gradually extends downward along the axial direction and obliquely in the circumferential direction. By arranging inclined guide structures on both the guide rod portion 4.4b and the bottom member guide protrusion 5.4, the adaptability of the two in the movement process can be improved.

[0050] Further, as shown in FIG. 7, a circumferential width of the guide channel 5.11 gradually decreases downward along the axial direction. In one embodiment, the circumferential width at a top portion of the guide channel 5.11 is greater than the circumferential width of the hook protrusion 4.4a, which facilitates the hook protrusion 4.4a smoothly entering the guide channel 5.11 along the axial direction.

[0051] Further, as shown in FIG. 6 and FIG. 7, the zipper lower stop further includes a plane member top board 4.2 fixed at a top end of the plane member cylinder 4.3 in the axial direction. The plane member top board 4.2 is provided with a rotating guide member 4.1 on its bottom surface in the axial direction, and the bottom portion of the rotating guide member 4.1 is located below the plane member cylinder 4.3 in the axial direction.

[0052] Meanwhile, the lower stop bottom member 5 is provided with a concave guide rail 5.1 on the top surface in the axial direction, specifically on a top surface of the bottom member ring board 5.13.

[0053] In the process that the plane member cylinder 4.3 enters the main groove 5.3 axially downwards, the rotating guide member 4.1 and the guide rail 5.1 can fit with each other in the circumferential direction and an oblique guiding is formed, to push the lower stop plane member 4 to rotate relative to the lower stop bottom member 5. When the lower stop plane member 4 moves axially until the lower stop plane board abuts against the lower stop bottom member 5 in the axial direction, the guide rail 5.1 abuts against the rotating guide member 4.1 in the circumferential direction.

[0054] Through the arrangement of the guide rail 5.1 and the rotating guide member 4.1, the guiding for the lower stop plane member 4 can be further improved, and at the same time, the guide rail 5.1 and the rotating guide member 4.1 are in circumferential contact with each other, and the rotation end point of the lower stop plane member 4 relative to the lower stop bottom member 5 can be effectively limited.

[0055] Further, the lower stop bottom member 5 is provided with a guide block 5.7 protruding upward from the top surface in the axial direction, specifically from the top surface of the bottom member ring board 5.13. In one embodiment, the guide block 5.7 and the guide rail 5.1 are sequentially arranged around the main groove 5.3 in the circumferential direction. As shown in FIGS. 6 and 7, the guide block 5.7 is provided with a guide slope, and the bottom surface of the plane member top board 4.2 is provided with an inclined portion 4.6. The inclined portion 4.6, the hook 4.4 and the rotating guide member 4.1 are sequentially arranged around the plane member cylinder 4.3 in the circumferential direction. When the plane member cylinder 4.3 enters the main groove 5.3 axially downwards, the guide slope and the inclined portion 4.6 can fit with each other in the circumferential direction and an oblique guiding is formed, to push the lower stop plane member 4 to rotate relative to the lower stop bottom member 5.

[0056] The arrangement of the guide block 5.7 and the inclined portion 4.6 can guide the lower stop plane member 4 in cooperation with the guide rail 5.1 and the rotating guide member 4.1, and the lower stop plane member 4 is guided at different positions in the axial direction during the rotation process, and the stability of the movement of the lower stop plane member 4 is improved.

[0057] Further, the lower stop plane member 4 is provided with a plane member magnet 4.9, and the lower stop bottom member 5 is provided with a bottom member magnet 5.10, and the plane member magnet 4.9 and the bottom member magnet 5.10 can magnetically attract each other. By mounting the magnets, it facilitates the alignment of the lower stop plane member 4 and the lower stop bottom member 5, and further convenient for users to quickly and easily combine the lower stop plane member 4 and the lower stop bottom member 5 together through the attractive force of the magnet and the rotating structure of the lower stop.

[0058] Further, the plane member magnet 4.9 is embedded in the plane member cylinder 4.3, and the bottom member magnet 5.10 is fixed in the main groove 5.3, which is convenient for magnet assembly. In one embodiment, as shown in FIG. 8, the top of the plane member cylinder 4.3 has an opening, and after the plane member magnet 4.9 is put into the inner cavity of the plane member cylinder 4.3 through the top opening, the plane member top board 4.2 is welded on the top opening. In the lower stop bottom member 5, the middle of the bottom member bottom board 5.2 is provided with a mounting hole. After the bottom member magnet 5.10 is mounted into the mounting hole, the bottom member bottom board 5.2 is welded to the bottom member ring board 5.13. The connection strength is high by adopting welding connection.

[0059] In another embodiment, as shown in FIGS. 9 to 12, the magnet may also be assembled on the lower stop in other ways, such as integrated molding. In one embodiment, by defining through-holes in the lower stop plane member 4 and the lower stop bottom member 5, the plane member magnet 4.9 is fixed by an ejector pin in the mold, and the plane member magnet 4.9 and the lower stop plane member 4 are molded together, and the bottom member magnet 5.10 is molded on the lower stop bottom member 5 by using the same method. This method is simple and convenient, however, it results in an extra hole structure in the lower stop. Compared to the previous magnet assembly method, the appearance is poor.

[0060] In addition to the zipper lower stop described above, a zipper is further provided according to the present application, which includes a zipper lower stop. The zipper lower stop may be the zipper lower stop provided in any one of the above embodiments, and the beneficial effects can be referred to the above embodiments accordingly.

[0061] The zipper further includes a slider 2, a first cloth tape 1.1 and a second cloth tape 1.2. The first cloth tape 1.1 and the second cloth tape 1.2 each are provided with a row of zipper teeth 3, and the slider 2 is connected to a lower stop plane member 4.

[0062] In one embodiment, as shown in FIG. 5, a plane member fixing board 4.5 is fixedly arranged on the outer peripheral surface of the plane member cylinder 4.3, a recess 4.7 is arranged on the plane member fixing board 4.5, and a bottom member connecting board 5.5 is fixedly arranged on the outer peripheral surface of the lower stop bottom member 5. The plane member fixing board 4.5 is fixed to the first cloth tape 1.1. The recess 4.7 extends along the moving direction of the slider 2, and an opening of the recess 4.7 faces the second cloth tape 1.2. The bottom member connecting board 5.5 is fixed to the second cloth tape 1.2.

[0063] As shown in FIG. 3, when the slider 2 contact to the lower stop plane member 4 along the moving direction, the plane member fixing board 4.5 is located in an inner cavity of the slider 2, and the bottom member connecting board 5.5 extends into the recess 4.7 and into the inner cavity of the slider 2 during the process that the hook protrusion 4.4a extends into the limiting groove 5.12. By adding the plane member fixing board 4.5 and the bottom member connecting board 5.5, the stability of the connection between the lower stop and the slider 2 can be improved.

[0064] In one embodiment, as shown in FIG. 3, the plane member fixing board 4.5 defines a slider fixing groove 4.8 at one end away from the lower stop plane member 4. When the slider 2 contacts to the lower stop plane member 4 along the moving direction, one end of the slider core 2.1 of the slider 2 close to the lower stop plane member 4 can abut against the slider fixing groove 4.8, to improve the stability of the slider 2 placed on the first cloth tape 1.1.

[0065] Further, as shown in FIGS. 1 to 5, the bottom member connecting board 5.5 is provided with a bottom member lead-in tooth 5.6 at one end away from the lower stop bottom member 5 in the moving direction of the slider 2. After the slider 2 moves in the direction away from the lower stop plane member 4 and the zipper teeth 3 on the first cloth tape 1.1 and the second cloth tape 1.2 are engaged, as shown in FIG. 1, the zipper teeth 3 on the second cloth tape 1.2 closest to the lower stop bottom member 5 and the bottom member lead-in teeth 5.6 jointly engage the zipper teeth 3 on the first cloth tape 1.1 closest to the lower stop plane member 4, to improve the adaptability between the lower stop and the zipper teeth.

[0066] In the zipper of this embodiment, when the two cloth tapes 1 are connected together, the slider 2 abuts against the lower stop plane member 4, and the slider core 2.1 stops at the slider fixing groove 4.8. With the lower stop plane member 4 on top and the lower stop bottom member 5 on the bottom, the plane member cylinder 4.3 on the lower stop plane member 4 is axially aligned with and extends into the main groove 5.3, and the hook 4.4 is axially aligned with the guide channel 5.11. The user drives the lower stop plane member 4 to move downward in the axial direction while rotating until the lower stop plane member abuts against the lower stop bottom member 5 in the axial direction. Then, the lower stop plane member 4 no longer moves axially downward. The user drives the lower stop plane member 4 to rotate, enabling the hook protrusion 4.4a to extend into the guide rod portion 4.4b, and allowing the lower stop plane member 4 and the lower stop bottom member 5 to be rotationally locked. During the rotation of the lower stop plane member 4, the bottom member connecting board 5.5 extends into the recess 4.7 and enters the inner cavity of the slider 2. Afterward, when the slider 2 is pulled, the bottom member lead-in teeth 5.6 are engaged with the zipper teeth 3 of the first cloth tape 1.1, and the zipper teeth 3 on the two cloth tapes 1 are engaged with each other.

[0067] The zipper in this embodiment can achieve the engagement of the lower stop through rotation, facilitating easy insertion and removal of the lower stop. During assembly, the plane member cylinder 4.3 and the main groove 5.3 are locked with each other in the axial direction and rotated and guided in the circumferential direction. The cooperation of the hook 4.4 and the bottom member guide protrusion 5.4 can further guide the rotational engagement of the lower stop plane member 4 and the lower stop bottom member 5. The guide block 5.7, in conjunction with the inclined portion 4.6, guides the lower stop plane member 4 to rotate again, to facilitate the sliding of the slider 2 for closure. These three cooperating parts serve as the rotating guide member 4.1, enabling the lower stop plane member 4 and the lower stop bottom member 5 to rotate into an engagement state. After that, the lower stop plane member 4 rotates. During this process, the hook protrusion 4.4a extends into the limiting groove 5.12, and the bottom member connecting board 5.5 extends into the recess 4.7 of the plane member fixing board 4.5, while the zipper teeth 3 close to the lower stop engage with each other to form a stable structure. In the axial direction, the circumferential direction and the radial direction, the lower stop plane member 4 and the lower stop bottom member 5 would not separate from each other, thus ensuring the strength of the lower stop. At the same time, the rotating structure of the lower stop, cooperated with the attraction between the plane member magnet 4.9 and the bottom member magnet 5.10, allows for quick and easy assembly of the lower stop.
