DETAILED DESCRIPTION

[0028] The present invention is further described in conjunction with the following examples.

[0029] A specific embodiment of a zipper head of the present invention is as follows Figure 1 As shown, the bag comprises an upper box body 11, a lower box body 12 and a zipper 2 for sealing the upper box body 11 and the lower box body 12, and the zipper 2 is provided with a pair of zipper heads 3. Figure 2 As shown, a hook 35 is formed at the top end of the zipper slider 3 , and a zipper piece 36 is hung between the hook 35 and the zipper slider 3 .

[0030] Please see Figure 2 and Figure 3 In this embodiment, a locking portion 32 is formed on the bottom surface of the zipper head 3. Specifically, the zipper head 3 has side panels 31 extending downward on both sides along the pulling direction, and a crossbeam is formed between the two side panels 31, which is the locking portion 32. A through hole 33 is formed by hollowing out between the crossbeam and the bottom surface of the zipper head 3. In order to prevent the zipper head 3 from hooking or scratching the clothes in the bag when it is pulled, the bottom surface of the side panel 31 is set to an arc surface. In order to further prevent the zipper head 3 from hooking or scratching the clothes in the bag when it is pulled, guiding inclined surfaces 34 are respectively provided at both ends of the bottom surface of the zipper head 3.

[0031] Please see Figure 4 The zipper lock includes a bottom shell 4 fixedly mounted on the inner side of the upper box body 11 or the inner side of the lower box body 12, and a driving component, a lock control component and a clamping mechanism are arranged in the bottom shell 4.

[0032] Please see Figure 4 , Figure 5 and Figure 8The clamping mechanism is located below the zipper 2 and is provided with a lock 51 that can reciprocate and is used to clamp the locking portion 32. There are two locks 51, and the clamping mechanism also includes a T-shaped pressing block 52. The two locks 51 are respectively arranged on both sides of the longitudinal section 523 of the T-shaped pressing block 52, and a lock spring 53 for lifting the lock 51 is arranged between each lock 51 and the bottom shell 4. The longitudinal section 523 of the T-shaped pressing block 52 is fixedly connected to the bottom shell 4, and the transverse section 521 of the T-shaped pressing block 52 is arranged along the pulling direction of the zipper 2 and is located below the zipper 2. In the locked state, the longitudinal section 523 of the T-shaped pressing block 52 is inserted into the through hole 33 of the zipper head 3, and the top end of the lock 51 abuts against the bottom surface of the longitudinal section 523 of the T-shaped pressing block 52 to clamp the locking portion 32. In order to facilitate the locking part 32 to escape from the locking buckle 51, when the locking part 32 is unlocked, the locking part 32 can press the locking buckle 51 downward under the action of external force to make it move downward. Because the locking buckle 51 is under the elastic force of the locking buckle spring 53, the locking buckle 51 can automatically return to its original position. The two side surfaces of the locking part 32 (the side surfaces perpendicular to the pulling direction of the zipper head) are provided with arc transition surfaces 321, such as Figure 3 As shown, when external force is applied to the zipper head 3 to unlock it, the arc transition surface 321 cooperates with the upwardly inclined guide surface 511 at the end of the lock buckle 51 to more smoothly push the lock buckle 51 downward, so that the zipper head 3 can smoothly detach from the lock buckle 51.

[0033] Please see Figure 4 and Figure 6 The lock control assembly includes a movable block 7 and a locking block 6. A sliding groove is provided at the bottom of the rear end of the locking block 6. A sliding bar is formed upward at the front end of the movable block 7. The sliding bar is inserted into the sliding groove so that the locking block 6 can slide along the axial direction of the sliding groove. Figure 8 As shown, the lock buckle 51 has a lock control portion 512 protruding outwardly from the side facing the lock control assembly, and the front end of the lock block 6 is formed with a lock tongue 61. When locking, the lock tongue 61 moves to the bottom surface of the lock control portion 512 to limit the lock buckle 51 from moving downward.

[0034] Please see Figure 4 and Figure 7 The driving assembly includes a return spring 9, which is obliquely installed between the locking block 6 and the bottom shell 4 to drive the locking block 6 to move horizontally or vertically.

[0035] Please see Figure 4 , Figure 8 and Fig. 9 The driving assembly also includes a code wheel assembly 8, which includes a wheel shaft and a code wheel and a code adjustment wheel 81 respectively sleeved on the wheel shaft. The code adjustment wheel 81 has a head and a rod. The code wheel is clamped on the head of the code adjustment wheel 81. The rod of the code adjustment wheel 81 has a groove 82 along its axial direction. The rear end of the movable block 7 extends a claw 71 toward the code adjustment wheel 81. In order to facilitate preparation and matching, the groove 82 and the claw 71 are both set in a triangular shape. See Figure 8 When locked, the claw 71 abuts against the outer side of the rod of the coding wheel 81. Figure 8 When unlocked, the claw 71 is inserted into the groove 82 of the rod of the coding wheel 81, see Fig. 9 In addition, the code wheel assembly 8 also includes a code adjustment switch sleeved on the end of the wheel shaft, and the function of the code adjustment switch is to adjust the code of the code wheel.

[0036] Please see Figure 4 , Fig.10 , Fig.11 and Fig.12 The drive assembly includes a pin lock assembly, and the pin lock assembly includes a lock core 300, see Fig.12 The bottom end surface of the lock core 300 extends a toggle portion 301 downward, and a push block 62 is formed on the side of the lock block 6 close to the lock core 300. When locking, the push block 62 is located on the side of the toggle portion 301. When unlocking, the lock core 300 rotates to drive the toggle portion 301 to rotate, and the toggle portion 301 rotates and pushes the push block 62 to make the lock block 6 move laterally.

[0037] In the zipper head of the present embodiment, when in the locked state, the push block 62 of the lock block 6 is in close contact with the side surface of the toggle portion 301 of the lock core 300, the claw 71 of the movable block 7 escapes from the groove 82 of the coding wheel 81 and abuts against the outer side surface of the coding wheel 81. At this time, the lock block 6 is in the maximum stroke, and the reset spring 9 is in the compressed state. The lock tongue 61 of the lock block 6 extends into the bottom surface of the lock control portion 512 of the lock buckle 51 and abuts against the lock control portion 512, limiting the up and down movement of the lock buckle 51. At the same time, the top end of the lock buckle 51 abuts against the longitudinal section 523 of the T-shaped pressure block 52, so that the locking portion 32 of the zipper lock is clamped between the lock buckle 51 and the T-shaped pressure block 52. Since the lock buckle 51 is in the limited state, the zipper head 3 cannot be pulled to achieve locking.

[0038] When the code wheel assembly 8 is unlocked, the code is correct. Under the elastic force of the reset spring 9, the reset spring 9 pushes the lock block 6 and the movable block 7 to move toward the code wheel assembly 8 until the claw 71 of the movable block 7 is stuck in the groove 82 of the coding wheel 81. After the lock block 6 moves, the lock tongue 61 of the lock block 6 moves out from the bottom end of the lock control part 512 of the lock buckle 51, thereby releasing the lock of the lock buckle 51 and completing the unlocking, so that the zipper head 3 can be pulled to open the bag.

[0039] When the pin lock is unlocked, the key is inserted to rotate the lock cylinder 300, and the lock cylinder 300 drives its toggle portion 301 to rotate. While the toggle portion 301 rotates, the toggle portion 301 pushes the push block 62 of the lock block 6 to move laterally. Since the lock block 6 and the movable block 7 are slidably matched, while pushing the lock block 6 to move laterally, the lock tongue 61 of the lock block 6 will also move laterally, so that the lock tongue 61 of the lock block 6 is misaligned with the lock control portion 512 of the lock buckle 51, thereby releasing the lock of the lock buckle 51 and completing the unlocking, so that a pulling force can be applied to the zipper head 3 to open the bag.

[0040] When locking, the zipper head 3 is pulled to the clamping mechanism (T-shaped pressing block 52), and then the driving assembly is switched to the locked state, and the locking can be completed.

[0041] It should be noted that the T-shaped pressure block 32 is configured to be T-shaped. The first purpose is to cooperate with the lock buckle 51 and limit the lock buckle 51 from popping out under the elastic force of the lock buckle spring 53. Another purpose is to guide the zipper head 3 to prevent the zipper head 3 from being correctly pulled to the working position of the clamping mechanism. After the transverse section 521 of the T-shaped pressure block 52 is inserted into the through hole 33 of the zipper head 3, the T-shaped pressure block 32 can also limit the freedom of the zipper head 3 in the vertical direction.

[0042] The zipper head of this embodiment forms a locking portion 32 at the bottom of the zipper head 3, and uses a locking mechanism disposed inside the bag to lock the zipper head 3, replacing the previous locking method outside the bag, making the bag look simpler. In addition, the locking mechanism is hidden inside the bag, further improving the anti-theft performance; when in use, the zipper head 3 only needs to be pulled to the position of the locking mechanism to be locked, and then the driving assembly is switched to the locked state, which is easy to operate.

[0043] Please see Figure 5 In order to make unlocking and locking smoother, guide surfaces 511 inclined upward are formed on both sides of the top end of the lock buckle 51. The guide surfaces 511 cooperate with the arc transition surfaces 321 of the locking portion 32, so that the locking portion 32 can be engaged with or disengaged from the lock buckle 51 more smoothly.

[0044] In this embodiment, in order to facilitate the assembly of the zipper lock, the zipper head further includes a cover 100 , which is located outside the bag and is detachably connected to the bottom shell 4 to be clamped on the upper box body 11 or the lower box body 12 .

[0045] Beneficial effects of the present invention: The zipper head of the present invention forms a locking portion 32 at the bottom of the zipper head 3, and uses a clamping mechanism arranged in the luggage to clamp and lock the zipper head 3, which replaces the previous method of locking outside the luggage. The appearance of the luggage is simpler. In addition, the locking mechanism is hidden in the luggage, which further improves the anti-theft performance. When in use, it is only necessary to pull the zipper head 3 to the position of the clamping mechanism and clamp it, and then switch the drive assembly to the locked state, which is easy to operate.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
