Description

Technical Field

[0001] This utility model is an anti-slip zipper head, belonging to the technical field of zipper head. Background Technology

[0002] A zipper pull generally consists of a zipper head body that engages with the zipper and a pull tab for the user to pull. Zipper pulls, in conjunction with zippers, are widely used in various garments, bags, and pouches. The pull tab of a zipper pull is typically a rectangular or round tab-shaped structure. When pulling the pull tab to move the zipper head body, the small contact area between the fingers and the tab makes it easy for the zipper to slip, requiring considerable force to grip the tab and zip the zipper open or close.

[0003] Patent No. CN214047800U describes an anti-slip zipper head. It consists of a zipper body and a connecting ring. The zipper body has a fixed pull tab lock, and the connecting ring is fitted onto the pull tab lock. The device also includes a pull tab and an anti-slip block. One end of the pull tab has a fixed collar, which is fitted onto the connecting ring. The end of the pull tab furthest from the collar is detachably connected to the anti-slip block, facilitating the user's pulling of the pull tab. However, because the connecting ring and the pull tab lock are fitted together, the connecting ring and the pull tab lock are inseparable. If the zipper body is damaged, all parts except the detachable anti-slip block must be replaced, resulting in waste. There is an urgent need for an anti-slip zipper head to solve the aforementioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an anti-slip zipper head to solve the problems mentioned in the background art. This utility model has a reasonable structure and good practicality. The threaded structure and telescopic limiting structure further improve the operability of the device's parts disassembly and assembly, allowing some parts to be separated. When the zipper body is damaged, only the zipper body needs to be replaced. At the same time, it has a good anti-slip effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-slip zipper head, comprising a zipper head body, a first L-shaped rod, a second L-shaped rod, and a knob. A pull tab lock is fixed to the front side of the zipper head body. A second screw hole is provided on the left side of the horizontal end of the first L-shaped rod, and a receiving groove is provided on the right side of the horizontal end of the second L-shaped rod. Guide grooves are provided on the upper and lower sides of the receiving groove. Guide strips are slidably installed in the two guide grooves. A square post is connected between the two guide strips. A second stud is fixed to the left end of the knob, and a first stud is fixed to the right end of the knob. A first screw hole is provided on the right side of the square post. A connecting rod is fixed to the lower end between the first L-shaped rod and the second L-shaped rod. A rectangular shell is sleeved on the outside of the connecting rod.

[0006] Furthermore, a pull tab is fixedly attached to the bottom of the rectangular shell, and the surface of the pull tab is provided with multiple anti-slip protrusions.

[0007] Furthermore, an anti-slip block is movably connected below the pull tab, and an anti-slip handle is fixedly connected below the anti-slip block.

[0008] Furthermore, the depth of the receiving groove is equal to the length of the square column.

[0009] Furthermore, the pull tab lock and the anti-slip handle are both U-shaped.

[0010] Furthermore, the knob has multiple rectangular protrusions on its annular side.

[0011] The beneficial effects of this utility model are as follows: This utility model provides an anti-slip zipper head. Because it incorporates a zipper head body, a pull tab lock, a first L-shaped rod, a second L-shaped rod, a connecting rod, a rectangular shell, a pull tab, an anti-slip block, an anti-slip handle, an anti-slip protrusion, a knob, a square post, a first stud, a second stud, and a guide strip, our design improvements and practical use have shown that this device has a reasonable structure and good practicality. The threaded structure and telescopic limit structure further improve the ease of disassembly and assembly of the parts, allowing some parts to be separated. When the zipper body is damaged, only the zipper body needs to be replaced. At the same time, it provides excellent anti-slip performance. Attached Figure Description

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1-6 This utility model provides a technical solution: an anti-slip zipper head, including a zipper head body 1, a first L-shaped rod 3, a second L-shaped rod 4, and a knob 11. A pull tab lock 2 is fixedly connected to the front side of the zipper head body 1. A second screw hole 17 is provided on the left side of the horizontal end of the first L-shaped rod 3, and a receiving groove 18 is provided on the right side of the horizontal end of the second L-shaped rod 4. Guide grooves 19 are provided on the upper and lower sides of the receiving groove 18, and guide strips 16 are slidably installed in the two guide grooves 19 respectively. A square post connects the two guide strips 16. 12. A second stud 14 is fixed to the left end of the knob 11, and a first stud 13 is fixed to the right end of the knob 11. A first screw hole 15 is provided on the right side of the square column 12. A connecting rod 5 is fixed to the lower end between the first L-shaped rod 3 and the second L-shaped rod 4. A rectangular shell 6 is sleeved on the outside of the connecting rod 5. This design solves the problem that in the original device, the connecting ring and the pull tab lock are sleeved together, making the connecting ring and the pull tab lock inseparable. If the zipper body is damaged, all parts except the detachable anti-slip block need to be replaced, resulting in waste.

[0022] In the first embodiment of this utility model: a pull tab 7 is fixedly connected to the bottom of the rectangular shell 6. The surface of the pull tab 7 has multiple anti-slip protrusions 10, which improve the anti-slip effect of the pull tab 7. An anti-slip block 8 is movably connected below the pull tab 7, and an anti-slip handle 9 is fixedly connected below the anti-slip block 8. The anti-slip block 8 and the anti-slip handle 9 allow the user to pull the zipper head body 1 in more ways. The depth of the receiving groove 18 is equal to the length of the square post 12. By setting the depth of the receiving groove 18 to be equal to the length of the square post 12, a perfect match is achieved. The pull tab lock 2 and the anti-slip handle 9 are both U-shaped, facilitating user lifting. Multiple rectangular protrusions are provided on the annular side of the knob 11, improving its anti-slip properties.

[0023] As a second embodiment of this utility model: when the zipper head body 1 is assembled with the zipper, the user can pull the zipper head body 1 by pulling any one of the following components: anti-slip handle 9, pull tab 7, pull tab lock 2, and the combination of the first L-shaped rod 3 and the second L-shaped rod 4. When it is necessary to separate the first L-shaped rod 3 and the second L-shaped rod 4, first turn the knob 11. At this time, the first stud 13 and the second stud 14 will rotate. The second stud 14 will be inserted into the first screw hole 15, and the first stud 13 will gradually disengage from the second screw hole 17. After the first stud 13 disengages from the second screw hole 17, push the second stud 14 to the left, so that the two guide bars 16 move along the two guide grooves 19 to move the square post 12, so that the square post 12 is inserted into the receiving groove 18. At this time, the horizontal end of the first L-shaped rod 3 and the horizontal end of the second L-shaped rod 4 are separated, and the first L-shaped rod 3, the second L-shaped rod 4, and the pull tab lock 2 can be separated.
