Description

Technical Field

[0001] The utility model relates to the technical field of zippers, in particular to a zipper for training clothing. Background Art

[0002] A zipper is a connector that connects or separates items by relying on continuously arranged chain teeth. It is now widely used in clothing, bags, tents, etc. Traditional zippers include a zipper head and a pull tab installed inside the zipper head. When wearing clothing with this zipper structure, during daily training, the pull tab will flip and move relative to the zipper head due to inertia, causing it to hit the human body and generate noise, which is a certain inconvenience. Utility Model Content

[0003] In order to overcome the shortcomings of the background technology, the technical solution adopted by the present invention is: a zipper for training clothes, including a zipper head, a pull tab and a latch, a mounting portion for mounting the pull tab is provided above the zipper head, the mounting portion is provided with a steering hole and an eccentric arc groove, the eccentric arc groove is eccentric to the steering hole, the pull tab is provided with a rotating shaft portion and an elastic portion, the pull tab is rotatably connected to the steering hole through the rotating shaft portion, the elastic portion is provided with a through hole for accommodating the latch, and the elastic portion is slidably connected to the eccentric arc groove through the latch.

[0004] By adopting the above technical solution, when the zipper is pulled, the pull tab rotates relative to the zipper head with the rotating shaft as the axis. When the elastic part passes through the eccentric arc groove, the elastic part produces elastic deformation and generates potential energy, so that the pull tab automatically moves into place and is automatically locked at the open or closed angle, thereby preventing the zipper from shaking and making abnormal noises during human activities, thereby improving wearing comfort.

[0005] The present invention is further configured such that the mounting portion is provided with a middle groove, the elastic portion is provided in the middle groove, and both ends of the latch are slidably connected to the eccentric arc grooves on both sides of the middle groove.

[0006] Furthermore, the mounting portion is provided with a limiting groove in the middle groove for controlling the rotation angle of the pull tab, and one end of the elastic portion is provided with a chamfered surface corresponding to the limiting groove.

[0007] Furthermore, a first positioning point and a second positioning point are respectively provided at both ends of the eccentric arc groove, and the distances from the first positioning point and the second positioning point to the steering hole are the same.

[0008] With the above technical solution, when the latch rotates to the first positioning point or the second positioning point, the elastic part naturally returns to its original position. When the latch rotates to the second positioning point, the elastic part abuts against the limiting groove to prevent the pull tab from rotating further.

[0009] The present invention is further configured such that the zipper head is integrally formed with an elastic portion, and the elastic portion extends to one side of the rotating shaft portion.

[0010] Furthermore, one end of the pull tab is provided with an opening groove and a protrusion for tactile identification.

[0011] By adopting the above technical solution, the elastic part extends to one side of the shaft part through a stamping and bending process, so that when the latch is installed on the elastic part, interference between the shaft part and the latch is avoided, and the overall structural design is reasonable.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] When the zipper is pulled, the pull tab rotates relative to the zipper head with the rotating shaft as the axis. When the elastic part passes through the eccentric arc groove, the elastic part produces elastic deformation and generates potential energy, so that the pull tab automatically moves into place, thereby preventing the zipper from shaking and making abnormal noises during human activities, and improving wearing comfort.

[0021] like Figure 1-3As shown, this embodiment provides a zipper for training clothes, including a zipper head 1, a pull tab 2 and a latch 3. A mounting portion 11 for mounting the pull tab 2 is provided above the zipper head 1. The mounting portion 11 is provided with a steering hole 12 and an eccentric arc groove 13. The eccentric arc groove 13 is eccentric to the steering hole 12. The pull tab 2 is provided with a rotating shaft portion 21 and an elastic portion 22. The pull tab 2 is rotatably connected to the steering hole 12 through the rotating shaft portion 21. The elastic portion 22 is provided with a through hole 23 for accommodating the latch 3. The elastic portion 22 is slidably connected to the eccentric arc groove 13 through the latch 3.

[0022] Combine Figure 4 As shown, in this embodiment, the mounting portion 11 is provided with an intermediate groove 14, the elastic portion 22 is provided in the intermediate groove 14, and the two ends of the pin 3 are slidably connected to the eccentric arc grooves 13 on both sides of the intermediate groove 14. The mounting portion 11 is located in the intermediate groove 14 and is provided with a limiting groove 15 for controlling the rotation angle of the pull tab 2. One end of the elastic portion 22 is provided with a chamfered surface 24 corresponding to the limiting groove 15, and the two ends of the eccentric arc groove 13 are respectively provided with a first positioning point 16 and a second positioning point 17, and the first positioning point 16 and the second positioning point 17 are at the same distance from the steering hole 12. The zipper head 1 is integrally formed with the elastic portion 22, and the elastic portion 22 extends to one side of the rotating shaft portion 21. One end of the pull tab 2 is provided with an opening groove 25 and a protrusion 26 for tactile identification.

[0023] In the present invention, a Y-shaped slideway 18 for passing the chain teeth is integrally formed at the bottom of the zipper head 1, and a mounting portion 11 is provided at the top, and a cutout 19 is provided between the mounting portion 11 and the zipper head 1. During installation, the rotating shaft portion 21 of the pull tab 2 is inserted into the steering hole 12 along the cutout 19, and the elastic portion 22 is inserted into the middle groove 14, pressing the mounting portion 11 and allowing the pull tab 2 to be rotatably connected to the zipper head 1. The pin 3 includes a pin shaft and a shaft sleeve, and the pin shaft and the shaft sleeve are installed on both sides of the pull tab 2 through an eccentric arc groove 13. The overall structure is simple and easy to install.

[0024] Combine Figure 5 As shown, the working principle of the present invention is that when the zipper is pulled, the pull tab 2 rotates relative to the zipper head 1 with the rotating shaft portion 21 as the axis, and the elastic portion 22 generates elastic deformation and potential energy when passing through the eccentric arc groove 13, so that the pin 3 automatically moves to the first positioning point 16 or the second positioning point 17, so that the pull tab 2 is automatically locked at the open or closed rotation angle, thereby preventing the zipper from shaking and generating abnormal noise during human activities.

[0025] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
