Background

Zippers are commonly used in the production and life of people, and clothes, open covers and the like are all provided with the application of the zippers. In the daily use process, due to improper use or insufficient strength of a product, the slider sometimes falls off from the zipper teeth and cannot be reinstalled on the zipper, so that the zipper and the product in which the zipper is positioned cannot be normally used, and waste is caused.

To solve this problem, the chinese patent application of the grant publication CN207707408U discloses a bi-directional slider, which is configured by clamping two ends of a mounting rib to the structures of an upper slider (upper board) and a lower slider (lower board), so as to realize detachable design of the mounting rib (connecting nose) and the pull ring (pull tab), thereby facilitating the detachment and replacement of the entire slider. However, in the application of the structure, since the mounting ribs are assembled only by means of two clamping structures, when a user pulls the pull ring, particularly in application scenes such as a tent, the user can pull the pull ring with a force which is inclined relative to the closing moving direction of the zipper, namely, the pull ring has a pulling force in an inclined direction to the mounting ribs, and since the mounting ribs are clamped on one side only (two ends of the mounting ribs are symmetrically arranged on one side of the moving direction of the zipper head), the pulling force in the inclined direction easily enables the mounting ribs to rotate by taking the two clamping points as axes, so that the mounting ribs drop together with the pull ring, the use experience of the user is affected, and even the zipper head is directly damaged.

When the connecting nose 2 is assembled on the pull head main body, two end parts of the connecting nose 2C-shaped structure and two end parts of the pull head main body tail end which are detachably connected into the connecting nose 2C-shaped structure are respectively clamped into the two tail end clamping grooves 42; and the middle part of the connecting nose 2C-shaped structure and the head end of the pull head main body are detachably connected to form the middle part of the connecting nose 2C-shaped structure, and the middle part is clamped into the head end clamping groove 41.

With continued reference to fig. 1, 2 and 3, the assembly process of the removable slider of the present embodiment is to align the ship plate positioning assembly 14 to assemble the upper ship plate 11 and the lower ship plate 12 on both sides of the fastener element of the zipper, and then lock the two with the ship plate screw 13. The connecting members 31 of the two pull tabs 3 are respectively sleeved at the two ends of the connecting nose 2, the two ends of the connecting nose 2 are respectively clamped into the two guide grooves 43 from the direction of the head end of the pull head main body, and the connecting nose 2 is pushed along the guide grooves 43. When the connecting nose 2 moves to a section with the inclined bottom of the guide groove 43 along the guide groove 43, the two end parts of the connecting nose 2 are stressed to generate elastic deformation to move towards opposite separation directions until the two end parts fall into the two tail end clamping grooves 42, the deformation is recovered, and the end parts are limited by the side parts of the tail end clamping grooves 42 and cannot be separated from the tail end clamping grooves 42. At the same time, the middle part of the connecting nose 2 is clamped into the head end clamping groove 41 and is limited by the groove wall of the head end clamping groove 41. When the connecting nose 2 is disassembled, only the two ends of the connecting nose 2 are required to be moved away from each other by a tool or the like until the ends of the connecting nose 2 can be separated from the tail end clamping groove 42. The detachable pull head is simple and convenient in structure, the production difficulty of each part is low, the assembly and disassembly processes are more convenient and quick, and the assembly of the connecting nose 2 can be realized only by clamping in; meanwhile, the arrangement of the guide groove 43 can enable the loading process of the connecting nose 2 to be more stable, and the assembly convenience is improved.
