Description

Technical Field

[0001] The utility model relates to the technical field of zippers, and in particular to a wear-resistant and anti-detachment resin zipper. Background Art

[0002] Zipper is a very common daily necessity. It relies on continuously arranged chain teeth to connect or separate objects. It is widely used in clothing, bags, and many other items. According to the material of the zipper, zippers are usually divided into three categories: metal zippers, resin zippers and nylon zippers. Resin zipper teeth are made of polyester plastic rice through dye matching and are arranged by injection molding machines.

[0003] The patent specification with announcement number CN216255778U discloses a wear-resistant and anti-slip resin zipper. By setting grooves, springs, telescopic rods, card balls and hemispherical grooves, the card rod and the lower baffle can be fixed more stably, so that the insertion rod can be stably located in the slot of the lower baffle, and the insertion rod will not easily fall out of the slot, thereby preventing the meshing chain teeth on the two chain cloths from separating from bottom to top; by setting a wear-resistant plate, the chain cloth can be prevented from being directly connected to the insertion rod. When the insertion rod is inserted into the slot, the chain cloth will be worn, thereby improving the strength and service life of the chain cloth; by setting a ball bearing, the chain head can slide more smoothly on the chain cloth, reducing the friction between the chain cloth and the chain head.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: during the use of the above device, the two sets of zipper racks below the zipper head are prone to accidental collapse. At this time, the zipper head needs to be removed. If it is pulled from below, it will be blocked by the collapsed zipper racks, making it difficult to pull the zipper head. The upper end of the zipper rack is blocked by the protruding block, which also makes it difficult to quickly remove the zipper head. Therefore, further improvement is needed. Utility Model Content

[0005] The utility model provides a wear-resistant and anti-detachment resin zipper, which solves the problem in the related art that it is inconvenient to detach the zipper head from the upper ends of the first zipper side strip and the second zipper side strip.

[0006] The technical solution of the utility model is as follows:

[0008] Preferably, a circular placement groove is provided on the upper inner wall of the placement groove, and a clamping groove is provided on the lower inner wall of the placement groove.

[0009] Preferably, the placement circular groove is communicated with the card slot.

[0010] Preferably, the slide groove is communicated with the placement circular groove.

[0011] Preferably, a spring is fixedly connected to the upper end of the limiting rod, and a handle rod is fixedly connected to the upper side of the outer surface of the limiting rod.

[0012] Preferably, the limit rod slides through the interior of the placement circular groove, the upper end of the spring is fixedly connected to the top inner wall of the placement circular groove, and the handle rod passes through the interior of the slide groove.

[0013] Preferably, a clamping block is fixedly connected to one side of the stopper, and a through groove is formed through the upper end of the clamping block.

[0014] Preferably, the card block corresponds to the card slot, the through slot is connected to the placement circular slot, and the through slot is also connected to the placement circular slot.

[0015] The working principle and beneficial effects of the utility model are:

[0016] The utility model pulls the handle bar toward the top of the first zipper side strip, and the handle bar drives the limit rod to slide along the slide groove inside the placement circular groove. At this time, the spring is compressed by the pressure of the limit rod, and after the lower end of the limit rod is moved to separate from the inside of the card slot and the through slot and enter the inside of the placement circular groove, the staff can pull the stopper to drive the card block to be taken out from the inside of the placement groove. At this time, the zipper head can be conveniently detached and removed from the upper ends of the first zipper side strip and the second zipper side strip, thereby solving the problem of inconvenience in detaching the zipper head from the upper ends of the first zipper side strip and the second zipper side strip.

[0017] The utility model places the card block inside the placement groove, and then the staff loosens the handle rod. At this time, the pressure on the spring disappears, and the spring will generate an opposite thrust, causing the spring to return to its initial state, that is, the spring will push the limit rod to slide inside the placement circular groove until the lower end of the limit rod enters the inside of the through groove and the card groove in turn. At this time, under the action of the limit rod, the card block can be prevented from detaching from the inside of the placement groove, and the stopper can be reinstalled and fixed.
