Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses a double-end zipper. Referring to fig. 1, the double-ended zipper includes a zipper tape 1, a first slider 2, a second slider 3 and a fixing assembly 4, wherein the first slider 2 and the second slider 3 are close to or far from each other along the zipper tape 1 to open or close the zipper tape 1, which is the prior art and will not be described herein in detail. Furthermore, a fixing assembly 4 is used to achieve fixing between the first slider 2 and the second slider 3. And then the situation that the first slider 2 and the second slider 3 slide along the zipper tape 1 direction is reduced, and the stability of the double-head zipper is improved.

Referring to fig. 2 and 3, specifically, the fixing assembly 4 includes an insert rod 41, a sleeve 42 and an insert block 43, the insert rod 41 is fixedly connected to an end surface of the first slider 2 facing the second slider 3, in this embodiment, the insert rod 41 is fixed with the first slider 2 by welding, and a length direction of the insert rod 41 is arranged along a length direction of the fastener tape 1. The sleeve 42 is fixedly connected to an end surface of the second slider 3 facing the first slider 2, in the present embodiment, the sleeve 42 is fixed to the second slider 3 by welding, and an outer contour of the sleeve 42 is rectangular. Meanwhile, the end surface of the sleeve 42 facing the first slider 2 is provided with a receiving groove 421, and the insert rod 41 is in inserted fit with the receiving groove 421. In addition, the slot 411 is opened on the upper surface of the insertion rod 41, when the insertion rod 41 is completely inserted into the accommodating slot, the insertion block 43 penetrates through the upper surface of the sleeve 42 and is in insertion fit with the slot 411, and meanwhile, the outer wall of the insertion block 43 is in butt fit with the inner wall of the opening portion of the sleeve 42, so that the insertion rod 41 and the sleeve 42 are limited in the horizontal direction.

Specifically, the upper surface of sleeve 42 is provided with installation pole 422, installation pole 422 cross-section is the setting of L type, the one end of installation pole 422 is through the upper surface of welded mode vertical fixation in sleeve 42, the lower surface of installation pole 422 is through the vertical spring 4222 that sets up of welded mode fixedly connected with, simultaneously, inserted block 43 is fixed in the one end that installation pole 422 was kept away from to spring 4222 through the welded direction, when inserted block 41 inserts to holding tank 421 completely and spring 4222 is in the natural state, inserted block 43 and slot 411 grafting cooperation. The end of the insertion block 43 and the end of the insertion rod 41 are both provided with an inclined surface, the inclined surface located on the insertion block 43 is inclined downwards towards the other side of the insertion rod 41 from one side of the insertion block 43 opposite to the insertion rod 41, and the inclined surface located on the insertion rod 41 is inclined downwards towards the other side of the insertion block 43 from one side of the insertion rod 41 far away from the insertion block 43, so that when the insertion rod 41 is inserted into the accommodating groove 421, the two inclined surfaces can slide relatively, and then the insertion block 43 is lifted more conveniently, so that the insertion rod 41 is completely inserted into the accommodating groove 421.

Further, a guide cylinder 4221 is vertically fixed to the lower surface of the mounting rod 422 by welding, the guide cylinder 4221 vertically penetrates, and the outer wall of the guide cylinder 4221 abuts against and engages with the inner wall of the spring 4222 to guide the movement of the spring 4222. The distance between the lower end face of the guide cylinder 4221 and the upper end face of the insert block 43 is greater than the length of a part of the block section of the insert block 43, which is in inserted fit with the slot 411, so that the condition that the guide cylinder 4221 blocks the insert block 43 before the insert block 43 is lifted upwards and separated from the slot 411 is reduced.

Furthermore, the end face of the insertion block 43 facing the spring 4222 is fixedly connected with a pulling rope 431 in a bonding manner, one end of the pulling rope 431 penetrates through the guide cylinder 4221 from bottom to top and penetrates through the upper surface of the installation rod 422, in the present embodiment, one end of the pulling rope 431 penetrating through the upper surface of the installation rod 422 is fixedly connected with a pulling ring 4311, in other embodiments, one end of the pulling rope 431 penetrating through the upper surface of the installation rod 422 can be fixed with blocks in various shapes, so that a user can conveniently pull the string by holding the pulling ring 4311 or the blocks with a hand. In addition, the outer diameter of the pull rope 431 is equal to the inner diameter of the guide cylinder 4221, and in the moving process of the pull rope 431, the outer wall of the pull rope 431 is always attached to the inner wall of the guide cylinder 4221, so that the situation that the pull rope 431 swings in the horizontal direction is reduced, and the moving stability of the pull rope 431 is improved.
