Description

Technical Field

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

[0002] An anti-stuck zipper is a zipper made with special design and technology to prevent it from getting stuck and being unable to be pulled during use.

[0003] During the use of the zipper, the friction between the gears will gradually increase, especially when the zipper surface is dry or there is dust or dirt, the friction is greater, and it is easy to cause it to get stuck. When the zipper is overstretched or pulled too tight, the gap between the gears becomes smaller, which is easy to cause it to get stuck. In addition, there are differences in durability and friction coefficient between zippers of different materials, and zippers of certain materials are more likely to get stuck.

[0004] When the user is pulling the zipper and the zipper is stuck, the user will subconsciously pull the zipper multiple times to solve the problem of the zipper being stuck. However, in this case, if the pulling force on the zipper is too large, the zipper cannot move due to the engagement of the zipper seat, which can easily lead to the breakage of the zipper teeth. Once the zipper teeth are damaged, the entire zipper is damaged. In addition, the existing zipper structure cannot effectively handle the stuck situation when the zipper is stuck.

[0005] Therefore, it is necessary to invent an anti-stuck zipper to solve the above problems. Utility Model Content

[0006] The utility model aims to provide an anti-stuck zipper to solve the above-mentioned shortcomings in the technology.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a kind of anti-stuck zipper, comprising a zipper seat, the bottom of which is a hollow structure, baffles are fixedly installed on both sides of the bottom of the zipper seat, the shape structure of the baffles is the same as the bottom side structure of the zipper seat, the bottom front end and tail end of the two baffles are fixedly installed with protrusions, a notch is provided in the horizontal middle position of the baffle, the notch separates one baffle into two parts, and the baffle is integrally formed with the zipper seat.

[0008] As a preferred solution of the utility model, a partition block is fixedly installed at the bottom of the zipper seat and between the two blocking pieces, and two sides of the partition block and the inner walls on both sides of the lower end of the zipper seat form two symmetrical cavities.

[0009] As a preferred solution of the utility model, baffle rods are laterally fixedly installed on the inner sides of the front and rear ends of the two baffles, and the baffle rods are made of metal. There is a certain gap between the front ends of every two baffle rods in the same group, and the baffle rod at the front end of the baffle does not contact the partition block.

[0010] As a preferred solution of the utility model, a cap is fixedly installed on the top of the zipper seat, and a pull tab is movably sleeved on the cap.

[0011] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0012] 1. Through the specially designed baffles and separators, as well as the horizontally fixed baffles, the zipper can effectively disperse the force when it is stuck, reducing the possibility of getting stuck. The metal material design of the baffles and baffles improves the durability of the zipper and reduces the wear rate. At the same time, the baffles do not contact the separators, which reduces the friction resistance and helps prevent the zipper from getting stuck. When the zipper seat of this structure is stuck, the baffles are opened by the protrusions, so that the zipper seat and the chain teeth can be quickly separated, making it convenient to separate the stuck chain teeth.

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] The utility model provides Figure 1-4 The anti-stuck zipper shown includes a zipper seat 1, the bottom of the zipper seat 1 is a hollow structure, the hollow structure design makes the zipper seat 1 have good strength and stability, can effectively withstand the tension during use, and the blocking pieces 2 on both sides of the bottom help prevent the zipper from getting stuck. Blocking pieces 2 are fixedly installed on both sides of the bottom of the zipper seat 1, and the shape and structure of the blocking pieces 2 are the same as the bottom side structure of the zipper seat 1. The front and rear ends of the bottom of the two blocking pieces 2 are fixedly installed with protrusions 4, and a notch 9 is opened in the horizontal middle position of the blocking piece 2. The notch 9 divides one blocking piece 2 into two parts, and the blocking piece 2 and the zipper seat 1 are integrally formed.

[0022] Furthermore, in the above technical solution, a partition block 5 is fixedly installed at the bottom of the zipper seat 1 and between the two baffles 2. The two sides of the partition block 5 and the inner walls on both sides of the lower end of the zipper seat 1 form two symmetrical cavities. The partition block 5 enables the zipper to better disperse the force when subjected to external force, thereby improving the stability of the zipper. The symmetrical cavity formed with the inner walls on both sides of the lower end of the zipper seat 1 helps to improve the anti-jamming performance of the zipper.

[0023] Furthermore, in the above technical solution, baffle rods 3 are laterally fixedly installed on the inner sides of the front and rear ends of the two baffles 2. The baffle rods 3 are made of metal. There is a certain gap between the front ends of every two baffle rods 3 in the same group. The baffle rods 3 at the front ends of the baffles 2 do not contact the dividing block 5. The baffle rods 3 and the baffles 2 can prevent the zipper from falling off from the bottom of the zipper seat 1.

[0024] Furthermore, in the above technical solution, a cap 8 is fixedly mounted on the top of the zipper seat 1 , and a pull tab 6 is movably sleeved on the cap 8 .

[0025] The anti-stuck zipper provided by the utility model has the following working process when in use:

[0026] First, install the zipper seat 1 on the zipper to ensure that the zipper teeth can smoothly pass through the cavities on both sides of the partition block 5. When the pull tab 6 is pulled, the zipper teeth will be guided by the baffle 3, allowing the zipper to move smoothly in the zipper seat 1. If the zipper is stuck, the user does not need to pull the pull tab 6 with excessive force. Because of the presence of the partition block 5, the zipper teeth will not be subjected to excessive squeezing force in this case, thereby reducing the risk of sprocket breakage. And when the zipper encounters a certain resistance, the baffle 3 at the front and rear ends of the baffle 2 will play a guiding role, allowing the zipper teeth to return to the correct track. If the zipper is still stuck, you can try to gently pull the pull tab 6 back and forth so that the zipper gradually returns to normal under the guidance of the baffle 3.

[0027] If the stuck zipper still cannot be unfastened or reset by pulling the zipper seat 1 back and forth, the protrusion 4 at the bottom of the blocking piece 2 can be clamped with pliers, and then the protrusion 4 can be pried to make the blocking piece 2 flip down a part. In this way, the blocking pieces 2 on both sides of the bottom of the zipper seat 1 are completely opened, and then the zipper is taken out of the cavity of the zipper seat 1, and the stuck part of the zipper is easily separated, and then the zipper seat 1 is installed, and the blocking piece 2 is pried back to the original position.

[0028] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
