Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0024] Example:

[0025] See Figure 1 - Figure 4 This embodiment relates to a zipper head that is easy to disassemble, specifically for the zipper opening and closing structure of everyday items such as clothing, bags, and shoes, and is particularly suitable for scenarios where zipper heads need to be frequently replaced or maintained. Through the structural design of this utility model, quick disassembly and installation of the zipper head are achieved, allowing users to replace the zipper head without tools, while ensuring the zipper head's sturdiness and stability during daily use.

[0026] Specifically, it includes: an upper chain plate 11, a lower chain plate 12, and a connecting block 13.

[0027] The connecting block 13 includes an upper connecting block 14 and a lower connecting block 15 that are hinged to each other. The upper connecting block 14 is fixedly disposed on the bottom surface of the upper chain plate 11, and the lower connecting block 15 is fixedly disposed on the top surface of the lower chain plate 12. The upper connecting block 14 and the lower connecting block 15 are fixed in position by a locking member 16.

[0028] The upper chain plate 11 is provided with a pull lug 21, and the pull lug 21 is connected to a pull tab 23 via a pull ring 22. The pull tab 23 is provided with an unlocking member 24 for driving the locking member 16 to rotate and unlock the upper connecting block 14 and the lower connecting block 15.

[0029] The locking member 16 includes a locking rod 25 and a locking flap 26. The lower connecting block 15 is provided with a locking groove 27. The locking flap 26 is located at the lower end of the locking rod 25 and is locked and adapted after being screwed into the locking groove 27.

[0030] Specifically, in this embodiment, the specific usage status of the zipper head and its operation steps are as follows:

[0031] In normal use, the upper chain plate 11 and lower chain plate 12 are tightly connected by the connecting block 13. The locking rod 25 in the locking member 16 is inserted into the locking groove 27 on the lower connecting block 15, and the locking flap 26 is stably embedded in the locking groove 27, thus ensuring the zipper head's stability in the closed state. The locking rod 25 of the locking member 16 is rotatably set inside the upper chain plate 11. When the user needs to disassemble or replace the zipper head, simply drive the locking rod 25 to rotate by the unlocking member 24 on the pull tab 23, causing the locking flap 26 to unscrew from the locking groove 27, releasing the locking state between the upper connecting block 14 and the lower connecting block 15. After unlocking, the upper connecting block 14 and the lower connecting block 15 are no longer constrained by the locking member 16, and they can rotate relative to each other through the hinge relationship. By slightly pulling the upper chain plate 11 by the pull tab 23, the upper connecting block 14 and the lower connecting block 15 can be separated, thus completing the disassembly of the zipper head. Similarly, when the zipper head needs to be replaced, simply close the upper connecting block 14 and the lower connecting block 15, so that after the locking rod 25 is inserted into the locking groove 27, the locking rod 25 is driven to rotate in the opposite direction by the unlocking component 24, so that the locking petal 26 is re-embedded into the locking groove 27, and the upper connecting block 14 and the lower connecting block 15 are closed and locked, restoring the normal use of the zipper head.

[0032] In this embodiment, two sets of locking flaps 26 are provided, symmetrically arranged at the lower end of the locking member 16. The locking groove 27 includes two sets of fan-shaped limiting parts 28 that slide and adapt to the locking flaps 26, so that when the locking rod 25 rotates, the two sets of locking flaps 26 can smoothly slide into their respective fan-shaped limiting parts 28. The upper chain plate 11 and the upper connecting block 14 are provided with circular through holes 29. After the upper end of the locking rod 25 passes through the circular through hole 29, its lower end is inserted into the locking groove 27 of the lower connecting block 15. Locking is achieved by the locking flaps 26 being screwed into the limiting parts for connection and engagement. The upper end of the locking rod 25 and the upper chain plate 11 are connected by a damped rotation method (for example, a rubber ring is sleeved on the outside of the locking rod 25 to increase the friction between it and the circular through hole 29 when rotating), ensuring that the zipper head is closed.

[0033] The lower connecting block 15 has an opening 31 for inserting the locking rod 25 and its two sets of locking flaps 26 into the locking groove 27. The limiting part of the locking groove 27 is located below the opening 31. After the locking rod 25 is inserted, it rotates to drive the locking flaps 26 into the limiting part. The opening 31 is adapted to the contour of the lower end of the locking member 16 (locking rod 25 and its two sets of locking flaps 26), so that the locking rod 25 and its two sets of locking flaps 26 can be inserted into the locking groove 27 from above the lower connecting block 15. After rotation, the zipper head is locked. At the same time, after the locking rod 25 is unlocked by rotating in the opposite direction, the lower end of the locking member 16 (locking rod 25 and its two sets of locking flaps 26) can be disengaged from the locking groove 27, so that the upper connecting block 14 and the lower connecting block 15 (upper chain plate 11 and lower chain plate 12) can be released from locking and opened along the hinge to disassemble the zipper head.

[0034] In this embodiment, the ends of the upper connecting block 14 and the lower interface are hinged to each other. Specifically, the end of the upper connecting block 14 is provided with a hinge seat 32, and the end of the lower connecting block 15 is provided with a hinge block 33. The hinge block 33 is hinged to the hinge seat 32 through a pin 34. The hinge seat 32 includes two sets of hinge plates disposed on both sides of the hinge block 33. Both the hinge block 33 and the hinge plates are provided with hinge holes 35 for the pin 34 to be inserted and adapted.

[0035] The upper end of the locking rod 25 has a slot 36, and the unlocking component 24 is provided with a plug 37 that is adapted to be inserted into the slot 36. The cross-sections of the slot 36 and the plug 37 can take various shapes, such as straight, cross, polygonal, flower-shaped, etc. In this embodiment, both the slot 36 and the plug 37 are straight, and the positions of the two sets of locking petals 26 correspond to the straight shape, so that when the unlocking component 24 is turned, the torque can be transmitted to the locking rod 25 to drive it to rotate and achieve unlocking or locking.

[0036] The pull tab 23 is made of a flexible material and has a recessed groove 38 for storing the unlocking component 24. One end of the unlocking component 24 is damped and hinged to the pull tab 23, and a drive knob 39 is provided at the hinge point to drive the pull tab 23 to swing out or retract from the recessed groove 38. The pull tab 23, through the design of the recessed groove 38, allows the zipper head to retract into the recessed groove 38 under normal use, which can prevent the user from being scratched by the plug 37 during use. The pull tab 23 is made of a flexible material (such as rubber, woven fabric, etc.). The unlocking component 24 is unfolded from the recessed groove 38 by driving the drive knob 39. The unlocking component 24 can only be inserted into the locking component 16 after the pull tab 23 is bent.

[0037] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
