Description

Technical Field

[0001] The utility model relates to the technical field of zippers, in particular to an anti-slip zipper. Background Art

[0002] A zipper is a connector that combines or separates items by means of continuously arranged chain teeth. It is currently widely used in the clothing industry, especially on pants. It usually includes a zipper tape and a zipper head. The zipper tape is pulled together or loosened by sliding the zipper head. During use, due to the lack of friction between the pull ring and the chain tape, especially in a wet or greasy environment, the zipper is prone to sliding downward due to its own weight under vibration, and the zipper opens, causing inconvenience and embarrassment. For example, a non-slip zipper is involved in the utility model with publication number CN201426446Y. The non-slip zipper is equipped with a pull ring on the top of the zipper lock; a hook is installed at the end of the zipper. When the zipper is locked, the pull ring on the zipper lock is hooked with the hook to prevent the zipper lock from sliding down and opening. This non-slip zipper can have an anti-slip effect, but the size of the hook installed on the clothes will affect its use effect. If the hook is too small, the zipper head is not easy to hang in the hook. If the hook is too large, it will affect the wearing effect. The prior art has the following problems: Therefore, it is necessary to develop an anti-slip zipper to address the above defects. Utility Model Content

[0005] Preferably, the anti-slip assembly includes a rotating shaft, a torsion spring and a shift block, the shift block is installed in the installation groove of the zipper head through the rotating shaft, the torsion spring is installed in the shift block, the torsion spring is sleeved on the rotating shaft and resets the shift block clockwise so that the inner end of the shift block abuts against the zipper teeth.

[0006] Preferably, the shift block includes an integrally formed limit rod, a movable rod and a support foot, the limit rod and the movable rod are connected to form an integral structure through the support foot, the inner end of the limit rod abuts against the zipper tooth, the limit rod is arranged in the mounting groove, the number of the support feet is two, both of which are distributed on the two side surfaces of the shift block, a circular hole is provided in the support foot, the support foot is sleeved on the rotating shaft, both ends of the rotating shaft are fixedly connected to the side walls of the mounting groove, the torsion spring is installed between the support feet, one foot of the torsion spring is inserted into the radial hole of the rotating shaft, and the other foot abuts against the inner side of the movable rod, and the movable rod is located on the outer side of the mounting groove.

[0007] Preferably, the handle comprises a pull ring and a handle head, the pull ring is installed in the pull nose of the zipper head, and the handle head is installed together with the pull ring through a pin.

[0008] Preferably, the width of the pull nose is adapted to the inner circle width of the pull ring.

[0009] Compared with the prior art, the beneficial technical effects of the utility model are:

[0010] The utility model anti-skid zipper controls the rotation of the anti-skid component through the pull ring when the zipper belt is closed, so that the front end of the limit rod is separated from the zipper teeth, so that the zipper is closed. When not in use, the pull ring is hung downward, and the torsion spring rebounds the shift block, so that the front end of the limit rod falls between the zipper teeth, so that the limit rod abuts against the zipper teeth, so that the zipper cannot be opened without the action of external force. The utility model has a simple structure and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] With reference to the accompanying drawings, Figure 1 This is a schematic diagram of the main structure of the anti-slip zipper of the utility model; Figure 2 It is a right side cross-sectional view of the utility model at A; Figure 3 It is a right side sectional view of the utility model at A (open state); Figure 4 It is a right side cross-sectional view of the utility model at A (pulled state); Figure 5 It is a schematic diagram of the anti-skid component of the utility model.

[0022] In a specific embodiment, Figures 1 to 5 As shown, an anti-skid zipper comprises a zipper tape 1 and zipper teeth 2 installed on the zipper tape 1; a zipper head 3 for closing or opening the zipper and a handle 4 arranged on the zipper head 3 are provided, a mounting groove 6 is provided in the middle of the top plate of the zipper head 3, an anti-skid component 5 is rotatably connected in the mounting groove 6, the inner end of the anti-skid component 5 can abut against the zipper teeth 2 to prevent the zipper teeth 2 from opening automatically without the action of external force, and the anti-skid component 5 and the handle 4 are hinged together through a connecting rod 7.

[0023] In a specific embodiment, Figures 1 to 5 As shown, the anti-slip assembly 5 includes a rotating shaft 51, a torsion spring 52 and a shift block 53. The shift block 53 is installed in the installation groove 6 of the zipper head 3 through the rotating shaft 51. The torsion spring 52 is installed in the shift block 53. The torsion spring 52 is sleeved on the rotating shaft 51 and resets the shift block 53 clockwise so that the inner end of the shift block 53 abuts against the zipper tooth 2.

[0024] In a specific embodiment, Figures 1 to 5 As shown, the shift block 53 includes a limiting rod 533, a movable rod 531 and a support leg 532. The limiting rod 533 and the movable rod 531 are connected as an integral structure through the support leg 532. The front end of the limiting rod 533 abuts against the zipper tooth 2. The limiting rod 533 is arranged in the mounting groove 6. There are two support legs 532, which are distributed on the two side surfaces of the shift block 53. A circular hole is arranged in the support leg 532. The support leg 532 is sleeved on the rotating shaft 51. Both ends of the rotating shaft 51 are fixedly connected to the side walls of the mounting groove 6. The torsion spring 52 is installed between the support legs 532. One leg of the torsion spring 52 is inserted into the radial hole of the rotating shaft 51, and the other leg abuts against the inner side of the movable rod 531. The movable rod 531 is located on the outer side of the mounting groove 6.

[0025] In a specific embodiment, Figures 1 to 5 As shown, the handle 4 includes a pull ring 401 and a handle head 402. The pull ring 401 is installed in the pull nose 301 of the zipper head 3, and the handle head 402 is installed with the pull ring 401 through a pin. The width of the pull nose 301 is adapted to the inner circle width of the pull ring 401.

[0026] The operation process of the anti-skid zipper of the utility model: when the zipper is used, Figure 4 As shown, the handle 4 is pulled upward to close the zipper, and the pull ring 401 in the handle 4 lifts the limit rod 533 through the connecting rod 7, and the front end of the limit rod 533 is separated from the zipper teeth 2, so that the zipper teeth 2 on both sides are smoothly engaged. Figure 2 As shown, when the pull ring 401 of the handle 4 is lowered, the torsion spring 52 will rebound the movable rod 531, so that the front end of the limiting rod 533 falls between the zipper teeth 2, and the front end surface of the limiting rod 533 abuts against the lower end of the zipper teeth 2, playing a parking brake role to prevent the zipper teeth 2 from being automatically opened. Figure 3 As shown, after the handle 4 is swung downward and outward and then pulled downward, the pull ring 401 will lift the limiting rod 533 through the connecting rod 7 to disengage from the zipper teeth 2, and the zipper can be opened. This structure is simple and easy to use.
