Description

Technical Field

[0001] The utility model relates to the technical field of zipper sliders, and more specifically, to an anti-jamming slider. Background Art

[0002] A zipper slider is a part of a zipper. It is usually made of metal or plastic and fixed at one end of the zipper for the user to easily open and close the zipper. The zipper slider usually has a gripping or rotating function to facilitate the user to operate the zipper in different situations.

[0003] In the patent with the publication number CN 205432418 U, an anti-jamming slider is disclosed, which includes an upper sliding seat, a lower sliding seat and a connecting column. The front end of the upper sliding seat is connected to the front end of the lower sliding seat through the connecting column. The distance between the front parts of the upper sliding seat and the lower sliding seat is greater than the distance between the rear parts of the upper sliding seat and the lower sliding seat. The distances at the front and rear between the upper sliding seat and the lower sliding seat are set separately. The distance at the front is set larger than the conventional range. In this way, when the chain belt is bent, the teeth between the front ends of the upper sliding seat and the lower sliding seat are more limited between the upper sliding seat and the lower sliding seat than in the conventional setting. When the slider is pulled, the teeth can smoothly slide to the rear of the slider without jamming the tape. The distance at the rear can be set within the conventional range, which can meet the meshing requirements and avoid jamming the tape within this range.

[0004] In the above device, the problem that the slider deforms due to improper force during long-term use is not solved. After the slider deforms, it will squeeze and rub the zipper more severely, resulting in the problem of tooth jamming. In addition, the function of cleaning the zipper is not provided on the slider, and the sundries attached to the zipper will also cause the slider to jam during movement.

[0005] For the problems in the related art, no effective solution has been proposed yet. Content of the Utility Model

[0006] In view of the problems in the related art, the utility model provides an anti-jamming slider to overcome the above technical problems existing in the prior related art.

[0007] Specifically, the technical solution adopted by the utility model is as follows:

[0008] An anti-jamming slider includes a lower fixing plate and an upper fixing plate. A separating and combining column is fixedly installed inside the lower fixing plate and the upper fixing plate. Side baffles are fixedly connected to the sides of the lower fixing plate and the upper fixing plate. A neodymium magnet is installed inside the side baffles. A brush member is installed inside the lower fixing plate and the upper fixing plate. A cylinder is fixedly connected to the top end of the upper fixing plate. A U-shaped member is rotatably installed on the outer side of the cylinder. A pulling plate is rotatably installed inside the right end of the U-shaped member.

A sliding strip is fixedly connected to the outer side of the separating and combining column, and the sliding strip of the separating and combining column is slidably installed on the inner wall of the second slot.

[0010] As a further solution of the present utility model, the lower fixing plate and the upper fixing plate are fixedly connected to the separating and combining column by welding.

[0011] As a further solution of the present utility model, the magnetism of the neodymium magnet in the lower fixing plate is opposite to that of the neodymium magnet in the upper fixing plate, and the neodymium magnet in the lower fixing plate and the neodymium magnet in the upper fixing plate are located on the same vertical line.

[0012] As a further solution of the present utility model, a first slot is provided at the inner side of the right end of the lower fixing plate and the upper fixing plate, and the brush member is slidably connected to the inner wall of the first slot.

[0013] As a further solution of the present utility model, mounting screws are screwed to the right ends of the lower fixing plate and the upper fixing plate, and the mounting screws are screwed to the brush member.

[0014] As a further solution of the present utility model, log stickers are pasted on the upper and lower ends of the pull plate.

[0015] The beneficial effects of the present utility model are as follows:

[0016] With the lower fixing plate, the upper fixing plate, the separating and combining column, the brush member, the U-shaped member, etc. provided in the present utility model, the distance between the lower fixing plate and the upper fixing plate can be positioned by the provided separating and combining column.
