DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] The zipper with a handle comprises left and right zipper chains 1, and a slider 2 for opening and closing the left and right zipper chains 1, a handle 3 connected to one end of each left and right zipper chain 1 for conveniently guiding the left and right zipper chains 1 to be inserted into the tooth groove of the slider 2 as shown in FIG. 1, or both ends are respectively connected with a handle 3 for conveniently guiding the left and right zipper chains 1 to be inserted into the tooth groove of the slider 2 as shown in FIG. 2 and FIG. 3. One end of the handle 3 is a connecting piece 4 for fixing with the cloth belt 5 of the zipper chain. The thickness of the connecting piece 4 with the fixed cloth belt 5 is not greater than the gap S between the upper cover plate and the lower cover plate of the slider 2 for the cloth belt 5 to pass through, as shown in FIG. 4. A slender guide rod 6 is connected next to the connecting piece 4. The guide rod 6 is connected to the chain teeth on the zipper chain. The height and width B of the guide rod 6 are not greater than the height and width B of the chain teeth, so that the two guide rods 6 can pass smoothly in the tooth groove of the slider 2. The handles 3 are made of non-rigid plastic and are connected to the left and right zipper chains 1 by hot melting. A fixing sleeve 7 is sleeved on the guide rods 6 of the same end handles of the left and right zipper chains 1 to prevent the ends of the left and right zipper chains 1 from being separated. The fixing sleeve 7 is sleeved on the guide rods 6 on the left and right zipper chains 1 and is also used as a stopper for the zipper to prevent the slider 2 from being pulled too far and detached from the zipper chains. The fixing sleeve 7 is a ring sleeve as shown in FIG. 5 or an 8-shaped sleeve as shown in FIG. 6. The ring sleeve fixes the two guide rods 6 together, and the 8-shaped sleeve inserts the two guide rods 6 into the 8-shaped holes. The fixing sleeve 7 is made of plastic. When one end of each of the left and right zipper chains 1 is connected to a handle 3, the other end is an opening element 10 of a block bottom stop 8 or a pin 9 as shown in FIG. 1. On the same-direction surface of the guide rod 6 of the handle 3 on each of the left and right zipper chains 1, there is provided digital markings from 1 to n uniformly distributed longitudinally, such as digital markings 11 from 1 to 5. A scale mark or arrow mark 12 is formed in the middle of the guide rod 6, and the arrow on the arrow mark 12 points to the digital markings 11 on the other guide rod 6 as shown in FIG. 3.

[0028] The application of the zipper with handles on a trolley case is shown in FIG. 7 (for clarity, it is a three-dimensional view of one side of the slider side of one of the case shells). The zipper with handles used is connected to the left and right zipper chains 1 with handles 3 at one end and opening elements 10 of a block bottom stop 8 and a pin 9 at the other end, as shown in FIG. 1. The left and right zipper chains 1 are sewn on the edges of the mating case shells 13, respectively, and the two ends of the left and right zipper chains 1 are located in the middle of the bent side of the two case shells 13, and the two ends of the left and right zipper chains 1 overlap in the middle of the bent side. The ends of the handles 3 connected to the left and right zipper chains 1 are respectively left with a section of about 0.8 to 1.3 cm not sewn with the edges of the case shells 13, so as to facilitate manual gripping of the handles 3 to insert the slider. On the left and right zipper chains 1, there are two opposite sliders with pull tabs 14, namely, the first slider 15 and the second slider 16 passing through the handles 3 on the outside of the case shells 13 for opening and closing the zipper. A third slider 18 with a pull tab 17 passing through the handles 3 is provided in the middle of the case shells 13 and disposed in the case shells 13. The third slider 18 pulls together the overlapping part of the left and right zipper chains 1 in the middle of the bent sides of the two case shells 13, thereby connecting the two case shells 13 together. It is also convenient to adjust the front and back tooth position between the left and right zipper chains 1 and separate and assemble the two case shells 13 when the relative positions of the two case shells 13 are asymmetrical. The first slider 15 and the second slider 16 are used for opening and closing the two case shells 13. The structure is sewn twice on each side of the overlapping part where the two case shells are connected, so it is stronger than other sections and easier to adjust the tension of the cloth belts.

[0029] The installation method of the zipper with handles on a trolley case is as follows: [0030] (1) Sewing: Separate the left and right zipper chains 1, and use the handles 3 as the starting point to sew the left and right zipper chains 1 to and around the edges of the two mating case shells 13 respectively, and overlap stitch to the opening elements 10 as shown in FIG. 7. [0031] (2) Inserting the first slider 15: insert the zipper chain with the block bottom stop 8 into the first slider 15 through the respective handle 3, and then pull the first slider 15 around the edge of the case shell 13 to the end of the respective opening element 10 without locking the two zipper chains, as shown in FIG. 8. [0032] (3) Inserting the second slider 16: the second slider 16 is opposite to the first slider 15. Use the left and right handles 3 to insert the left and right zipper chains 1 into the second slider 15 at the same time to engage the teeth, then pull the second slider 15 to the customs lock 19 position, and insert the pin 9 into the first slider 15 and the block bottom stop 8, and then use the opening elements 10 and the first slider 15 to mesh the left and right zipper chains 1 as shown in FIG. 9, and also pull the first slider 15 to the customs lock 19 position, so that the first slider 15 and the second slider 16 are both side by side at the customs lock 19 position, and then place the trolley case upright and test whether the four rollers 20 at the bottom of the case shells touch the ground at the same time, that is, whether the two case shells 13 are completely aligned. [0033] (4) Adjustment: if the two case shells 13 are not completely aligned and are biased to the left or right, move the first slider 15 back to the end of the opening elements 10 and open the opening elements 10. At this time, the lower layers of the left and right zipper chains 1 are exposed, and then operate the left and right handles 3 to appropriately open the zipper chains 1 and insert the third slider 18 through the left and right handles 3, and then adjust the front and rear positions of the right and left handles 3 relative to the third slider 18 in reverse manner according to the left and right deflection degree of the two case shells 13, as shown in FIGS. 7 and 10. If the four rollers 20 have not yet reached a balanced state of landing at the same time, i.e. the two case shells 13 have not been completely aligned, the above step (4) is repeated. By adjusting the chain engagement of the left and right zipper chains 1 at the front and rear position difference of the third slider 18, the balance correction of landing of the four rollers 20 at the same time is performed. After the balance correction of the chain engagement meets the requirements, the fixing sleeve 7 is put on the left and right handles 3 as shown in FIGS. 11 and 12. [0034] (5) Finally, at the opening elements 10 of the left and right zipper chains 1, through the first slider 15 and the engagement of the opening elements 10, the left and right zipper chains 1 are meshed again, thereby completing the entire installation and adjustment.

[0035] The third slider 18 described above is an automatic locking slider or a semi-automatic locking slider with a stopper to prevent the items in the trolley case from touching the third slider 18, so that the third slider 18 moves and the left and right zipper chains 1 are automatically pulled apart. Of course, the third slider 18 may also be an ordinary slider without a stopper.

[0036] Of course, the above examples are only preferred embodiments of the present invention, but do not limit the scope of implementation of the present invention. All equivalent changes and modifications made within the scope of this application are still within the scope of protection covered by the present invention.
