DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0032] See also Figure 1 A detachable closed-end zipper in this embodiment includes two cloth tapes 1, and teeth 2 are fixed on opposite sides of the two cloth tapes 1. The teeth 2 are provided with a pull head 3, and the cloth tapes 1 are provided with a locking mechanism 4.

[0033] It should be noted that the detachable closed-end zipper can enhance the tight connection between the stoppers through the locking mechanism 4, thereby improving the stability and durability of the zipper and making the operation more convenient.

[0034] See also Figures 1 to 4In order to improve the stability and durability of the zipper, the locking mechanism 4 in this embodiment includes a left lower stop 401 fixed to the right side of the left end cloth tape 1, a right lower stop 409 fixed to the left side of the right end cloth tape 1, an adjustment component and a limiting component. The adjustment component includes two adjustment blocks 402, two adjustment blocks 403, two connecting blocks 404, two first springs 405 and two moving blocks 406 slidably connected to the left lower stop 401. The front and rear sides of the left lower stop 401 are both provided with a first adjustment groove 407 with a convex cross-section. The first adjustment groove 407 is slidably connected to the adjustment block 402, thereby ensuring the smoothness of the adjustment block 402 and the moving block 406 during the movement, so that the adjustment block 402 will not move out of the first adjustment groove 407. The two first adjustment grooves 40 The opposite sides of the two adjusting blocks 402 are connected with the second adjusting groove 408 provided on the left lower stop 401, and the second adjusting groove 408 is slidably connected with the moving block 406. The first spring 405 is located between the adjusting block 402 and the first adjusting groove 407. The opposite sides of the two adjusting blocks 402 are fixed to the opposite sides of the two adjusting blocks 403, respectively. The opposite sides of the two connecting blocks 404 are fixed to the opposite sides of the two adjusting blocks 402, respectively. The opposite sides of the two moving blocks 406 are fixed to the opposite sides of the two connecting blocks 404, respectively. The first spring 405 is sleeved on the outer surface of the connecting block 404. By pressing the adjusting block 403, the adjusting block 402 and the connecting block 404 can be driven to move, and then the moving block 406 is pushed to adjust the position of the limit assembly.

[0035] The limiting assembly includes two fixed blocks 410 slidably connected to the right lower stop 409, two sets of guide blocks 411, two second springs 412 and two first limiting blocks 413. A first limiting groove 414 is provided on the left side of the right lower stop 409. The first limiting groove 414 is slidably connected to the first limiting block 413. The fixed block 410 slides in contact with the moving block 406 to provide a certain guide for the movement of the right lower stop 409, so that the position of the fixed block 410 can be adjusted by the moving block 406. The front and rear sides of the right lower stop 409 are both provided with moving grooves 416. The cross-section of the movable groove 416 is convex, and the movable groove 416 is slidably connected to the fixed block 410, so that the fixed block 410 can always move stably in the movable groove 416 and will not move out. The opposite sides of the two fixed blocks 410 are respectively fixed to the opposite sides of the two second springs 412, and the left and right sides of the fixed block 410 are respectively fixed to the opposite sides of the two guide blocks 411. The fixed block 410 can be squeezed out of the second adjustment groove 408 by moving the movable block 406, so that the right lower stop 409 can be pulled to move it out of the interior of the fixed groove 415.

[0036] At the same time, the left and right sides of the movable groove 416 are connected with a guide groove 417 opened on the right lower stop 409 and slidably connected with the guide block 411, providing a guide for the sliding of the fixed block 410 in the movable groove 416, ensuring the stability and accuracy of the movement of the fixed block 410, and a fixed groove 415 is opened on the right side of the left lower stop 401, and the fixed groove 415 is slidably connected to the right lower stop 409, so that the fixed groove 415 can be closely matched with the right lower stop 409 during the adjustment process, ensuring the stability of the fixation between the left lower stop 401 and the right lower stop 409.

[0037] In this embodiment, when the detachable closed-end zipper is closed, the locking mechanism 4 can be conveniently operated to enhance the tight connection between the stoppers, thereby improving the stability and durability of the zipper.

[0038] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0039] The working principle of the above embodiment is:

[0040] (1) In the process of operating the zipper, the fixing block 410 needs to be gently pressed into the movable groove 416. At this time, the second spring 412 is in a compressed state, preparing for the subsequent automatic reset of the fixing block 410. When the fixing block 410 completely enters the movable groove 416, the right lower stop 409 can be smoothly pushed into the left lower stop 401 along the fixing groove 415 through the movement of the fixing block 410. In this process, the first limiting block 413 and the first limiting groove 414 cooperate closely to provide a stable guide for the right lower stop 409 to ensure that it can enter the fixing groove 415 accurately. As the right lower stop 409 is fully inserted, the elastic force of the second spring 412 begins to play a role, pushing the fixing block 410 back to the initial position, thereby enabling the fixing block 410 to move into the second adjustment groove 408 and fit closely with the inner wall of the groove, thereby achieving a stable connection between the right lower stop 409 and the left lower stop 401, thereby enhancing the overall stability and reliability of the zipper.

[0041] (2) When it is necessary to separate the left lower stop 401 and the right lower stop 409, it is only necessary to press the adjustment block 403, which will drive the adjustment block 402 and the connecting block 404 to move together, and then push the moving block 406 to squeeze the fixed block 410 out of the second adjustment groove 408, so that the right lower stop 409 can be separated from the left lower stop 401. The whole process is simple and quick. Through the operation of the locking mechanism 4, the user can easily maintain the close connection between the stop parts, thereby further improving the overall stability and reliability of the zipper. This design not only facilitates the user's use, but also ensures the stability and durability of the zipper under various conditions.
