DETAILED DESCRIPTION OF THE EMBODIMENT'S

[0042] To make the technical means, creative features, goals, and effects achieved by the present invention easy to understand, the following further explains the present invention in conjunction with specific embodiments.

[0043] Referring to FIGS. 2 to 5, an improved watchband adjustment unit 100 of the present embodiment includes: a fixing unit 1, a fixing member 2, a rotating member 3, and an interference fit rod fixing assembly 4. The fixing member 2 and the rotating member 3 are respectively mounted on both sides of the fixing unit 1. The interference fit rod fixing assembly 4 secures the fixing member 2, the fixing unit 1, and the rotating member 3. Specifically, a first clamping and fixing channel is formed by the cooperative molding inside the fixing member 2, the fixing unit 1, and the rotating member 3. The fixing member 2 and the rotating member 3 cooperatively mold a second clamping and fixing channel. An elastic member 42 is retained by the interference fit rod 41 and a clamping limiter molded within the fixing member channel segment in the first clamping and fixing channel. The interference fit rod fixing assembly 4 includes: an interference fit rod 41 that passes through the fixing member 2, the fixing unit 1, and is interference-fitted to the rotating member 3, the elastic member 42 retained by the interference fit rod 41 and the clamping limiter, a first fixing rod 43 interference-fitted to the fixing member 2 and detachably clamped to the rotating member 3 in the second clamping and fixing channel, and a second fixing rod 44 interference-fitted to the fixing member 2 and the fixing unit 1 located between the interference fit rod 41 and the first fixing rod.

[0044] More specifically, the interference fit rod 41 has clamping and fixing patterns protruding from the outer periphery of the end that is interference-fitted to the rotating member 3. Each clamping and fixing pattern is parallel to the length of the interference fit rod 41, with adjacent patterns forming grooves. The other end has a clamping limiter for the elastic member 42. The fixing member channel segment includes two hollow cylinders of different diameters, with the smaller diameter cylinder facing the fixing unit 1. The height of the smaller diameter cylinder is 1 mm-2 mm.

[0045] In this embodiment, the fixing member 2 and the rotating member 3 are square-shaped, and the assembled watchband adjustment unit 100 is axially symmetrical.

[0046] Specifically, if the elastic member 42 is installed inside the rotating member 3, virtual space is created when the rotating member 3 rotates and disengages from the interference fit rod 41, increasing the alignment difficulty. In the present invention, the elastic member is installed inside the fixing member's clamping limiter, effectively avoiding virtual space and facilitating accurate alignment without adjustment, making the installation simpler.

[0047] Specifically, the watchband adjustment unit is assembled from multiple fixing units 1 in sequence. When the length of a single fixing unit 1 exceeds 9 mm, a second fixing rod 44 is interference-fitted between the fixing member 2 and the fixing unit 1. This results in the fixing member 2 and the fixing unit 1 being connected by two connecting rods, namely the second fixing rod 44 and the interference fit rod 41. This configuration improves the connection stability between the fixing unit 1 and the fixing member 2, making it difficult for the fixing member 2 and the fixing unit 1 to rotate relative to each other, thereby further enhancing the overall strength of the watchband.

[0048] In this embodiment, the fixing unit 1, the fixing member 2, and the rotating member 3 are all made of the same material, which can be metal or hard plastic. The connection strength of the assembled metal or hard plastic watchband is high, and it is not easy to loosen.

[0049] In a preferred embodiment, the first fixing rod 43 is parallel to the interference fit rod 41 and is respectively installed on both sides of the fixing member 2 and the rotating member 3 in the direction of the watchband's length. After pulling the rotating member 3 outward, the rotating member 3 rotates around the central axis of the first clamping and fixing channel. When the elastic member 42 is in a non-compressed state, the interference fit rod segment within the fixing member channel section is greater than or equal to the insertion section of the first fixing rod 43 into the rotating member 3. The part of fixing unit 1 that protrudes from fixing member 2 and rotating member 3 has an axle hole channel that is parallel to the width of the watchband. This axle hole channel is penetrated and connected by the corresponding first fixing rod of the adjacent watchband adjustment unit. In this embodiment, the first fixing rod 43 is located on one side of the fixing unit 1 in the direction of the watchband's length, while the axle hole channel is located near the other side of the fixing unit 1 in the same direction. When assembled, the fixing member 2, the fixing unit 1, the rotating member 3, and the first fixing rod 43 form a convex shape.

[0050] The structural design of this product involves installing the elastic member 42 inside the fixing member 2, facilitating the control of force when pulling and rotating the product. The rotating member 3 rotates around its axial hole section, which forms the first clamping and fixing channel, avoiding wear caused by positional restrictions in existing technology. Additionally, the assembly method of the interference fit rod 41 and the elastic member 42 is simple and reliable, simplifying the product structure and effectively reducing production costs.

[0051] As can be seen from the above description, the structural design of this product overcomes the phenomenon of scratched products in existing technology. It is quick to assemble and effectively reduces production costs.

[0052] Referring to FIGS. 6 and 7, the difference in this improved embodiment of the watchband adjustment unit 100 is that the fixing member 2 is T-shaped. The T-shaped fixing member 2 has two crossbars that are parallel to the watchband's length and width directions, respectively. The two crossbars include a protruding crossbar h that is parallel to the watchband's width direction and a short crossbar that is parallel to the watchband's length direction. The first clamping and fixing channel and the second clamping and fixing channel are located on both sides of the protruding crossbar h, and the fixing unit 1 is located on one side of the short crossbar. The T-shaped structure of the fixing member 2 improves product stability. When the rotating member 3 is pulled outward, the interference fit rod 41 and the limiter work together to compress the elastic member 42. At this time, the rotating member 3 separates from the first fixing rod 43. When rotational force is applied to the rotating member 3, it rotates around the central axis of the interference fit rod 41, allowing the rotating member 3 to move outward while rotating. This structural design ensures good force control when pulling the rotating member 3 outward and effectively overcomes the wear phenomenon present in existing technology.

[0053] Specifically, the T-shaped fixing member 2 has two crossbars: the protruding crossbar h, which is parallel to the watchband's width direction, and the short crossbar, which is parallel to the watchband's length direction. The width of the protruding crossbar h is 0.04-0.06 mm longer than the width of the fixing unit 1, ensuring that the fixing unit 1 fits precisely between the T-shaped fixing member 2 and the rotating member 3. Furthermore, the width of the short crossbar is not less than 1.8 mm. Since the elastic member 42 is installed inside the short crossbar of the T-shaped fixing member 2, the length of the elastic member 42 in the compressed state is 0.75 mm, and it has a 0.8 mm stroke after rebound when disassembled. Therefore, the width of the short crossbar being not less than 1.8 mm ensures the stable installation of the elastic member 42 and the clamping limiter. The entire watchband's structure is compact and has high precision, which is conducive to improving the product's added value.

[0054] Specifically, in this embodiment, one end of the crossbar of the watch band adjustment unit 100, which is parallel to the width direction of the watch band, abuts and positions the rotating member 3, and the left and right sides of the crossbar respectively abut the fixing unit 1, one side, and the adjacent side of the fixing unit. For other structures, please refer to the description of the above embodiments, which will not be repeated here.

[0055] In this embodiment, the strap adjustment unit 100 installs the elastic member 42 within fixing member 1 and fixing member 2, facilitating control of the force when pulling and rotating the product. Simultaneously, the rotating member 3 rotates around the central axis of its card slot shaft hole section, which constitutes the first card fixing channel, avoiding the wear phenomenon caused by the positional relationship limitations in existing technology. Additionally, the interference connection rod 41 and elastic member 42 assembly method also has the advantage of being simple and reliable. This structural design simplifies the product structure and effectively reduces production costs. Furthermore, fixing member 2 is set in a T-shape, with the protruding crossbar h parallel to the width direction of the strap abutting against rotating member 3, further enhancing the stability of the assembled product.

[0056] Referring to FIGS. 8 and 9, the difference between this embodiment and the embodiment in FIGS. 6-7 is that on the protruding crossbar h, which is parallel to the width direction of the strap, a third fixing rod a is installed. This third fixing rod a is respectively fixed to the protruding crossbar h and detachably connected to the rotating member 3. One end of the third fixing rod a is interference-fitted to the protruding crossbar h, while the other end is detachably connected to the rotating member 3. When the rotating member 3 is pulled outward, the third fixing rod a disengages from the rotating member 3.

[0057] The installation of the third fixing rod a allows the rotating member 3 to form three connection points with the fixing member 2. Specifically, the rotating member 3 is connected to the T-shaped fixing member 2 via the interference connection rod 41; connected to the other side of the T-shaped fixing member 2 via the second fixing rod 42; and connected to the protruding crossbar h of the T-shaped fixing member 2 via the third fixing rod a. This greatly enhances the connection stability of the rotating member 3. Even if one of the fixing rods becomes loose, it will not cause the entire rotating member 3 to fall off. The product has high structural strength and good stability.

[0058] In use, pulling the rotating member 3 outward causes the interference connection rod 41 to compress the elastic member 42 in tandem. The rotating member 3 disengages from the first fixing rod 43 and the third fixing rod a. By rotating the rotating member 3 around one side, the interference connection rod 41 compresses the elastic member 42, installed inside the fixing member 2, with the rotating member 3 driving the interference connection rod 41. This ensures good force stability of the rotating member 3, avoiding the issue of poor force application that can lead to operational errors and product wear. Additionally, the product's structural design is simple, reducing the number of components and effectively lowering production costs.

[0059] Referring to FIGS. 4 and 5, the difference between this embodiment and the previously mentioned embodiments is that the fixing unit 1 is square. The fixing member 2, the rotating member 3, the interference connection rod 41, and the first fixing rod 43 are assembled in a square shape.

[0060] Referring to FIG. 10, the assembled adjacent adjustment units are shown as 7-1. When the rotating member 3 is pulled outward, the first fixing rod 43 separates from the rotating member 3, as shown in 7-2. After applying a rotational force to the rotating member 3, as shown in 7-3, the interference connection rod (screw) 41 and the limiting part compress the elastic member 42. By rotating the rotating member 3 to the position shown in 7-3, the adjacent adjustment unit installed through the first fixing rod 43 can be slid and disassembled in the direction of the rotating member 3, as shown in 7-4, thereby completing the strap adjustment function. For assembly, perform the reverse operation.

[0061] It should be noted that in some embodiments, as shown in FIG. 11, a fixing adhesive is installed in the gap between the screw rod 41 and the rotating member 3. After the screw rod 41 is threaded with the rotating member 3, adhesive is injected into the gap between the two connections to form the fixing adhesive, securing the screw rod 41 and the rotating member 3. This structural setup enhances the stability of product assembly and overcomes the looseness defect of product structures in existing technology. When adjusting the strap length, a set of adjustment units is usually disassembled as a whole. During the assembly of the screw rod 41 and the rotating member 3, this embodiment uses a fixing adhesive to further secure the connection during threading, improving the connection stability of the screw rod 41 and the rotating member 3, which is beneficial for strap length adjustment.

[0062] In other embodiments, laser welding can also be used to fix the screw rod 41 and the rotating member 3. Of course, the means of fixation between the two are not limited to the aforementioned methods. This fixation method helps to overcome the looseness defects in existing technology.

[0063] Referring again to FIG. 11, the screw rod 41 and the first fixing rod 43 are parallel to the width direction of the strap and are respectively located on either side of the rotating member 3 and the fixing member 2 along the length direction of the strap. The fixing member's shaft hole channel section is parallel to the width direction of the strap and is formed through the fixing member 2. The belt grain shaft hole channel section of the fixing unit 1, together with the fixing member's shaft hole channel section and the rotating member's shaft hole channel section, constitutes the first shaft hole channel. The fixing unit 1 also has a second belt grain shaft hole channel formed parallel to the fixing member's shaft hole channel section, and both are respectively located on either side of the length direction of the strap. The fixing unit 1 is square in shape, and the fixing member 2, rotating member 3, screw rod 41, and first fixing rod 43 are assembled in a square configuration.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
