Abstract
Description
Technical Field
[0001] This utility model relates to the field of luggage lock technology, specifically to a modular luggage lock that is easy to assemble. Background Technology
[0002] Chinese patent document CN106285216B discloses a zipper combination lock, relating to the field of lock technology. Its structure includes a hook that engages with the zipper, a locking block for abutting against the hook to lock, and an unlocking mechanism. By using a locking block that is itself a spring-loaded structure, before locking, the hook is in the unlocked position. To lock, the zipper is held so that it engages with the hook, and pressing the hook compresses the locking block, causing it to elastically deform. At this point, the hook passes over the locking block. Then, the zipper is released, and the locking block springs back and abuts against the hook, preventing it from returning to the unlocked position, thus locking the lock. By using a locking block with its own spring-loaded structure instead of the reset element in the prior art, one-handed operation is still possible during locking, thus achieving convenient locking.
[0003] In the aforementioned prior art, the locking block and the base plate are integrally formed, with the fixed end of the locking block fixed to the base plate and the free end of the locking block tilting upwards, possessing elasticity that allows downward movement. The lock hook is supported by a protrusion erected on the lock housing base plate. This structure results in scattered parts during assembly, increasing assembly difficulty and cost. Furthermore, for locks of different specifications, new molds are required to accommodate the corresponding locking block and base plate, leading to high costs. Summary of the Invention
[0004] In view of the above-mentioned technical problems, the present invention provides a modular bag lock that is easy to assemble.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A modular, easily assembled bag lock is provided, comprising a lock housing, a keyhole located within the lock housing, and a locking hook located within the lock housing at a position corresponding to the keyhole for engaging with a zipper, characterized in that:
[0007] The lock housing also includes an integrated base, which includes a locking part for abutting against the lock hook to achieve locking and a support part for supporting the lock hook.
[0008] Including the unlocking mechanism, the locking part is an elastic structure that can swing up and down.
[0009] During the locking process, the locking hook squeezes, causing the locking part to elastically deform and pass over the locking part. Then the locking part rebounds and pushes against the locking hook, preventing the locking hook from returning to its original position, thereby achieving locking.
[0010] During the unlocking process, the unlocking mechanism compresses the locking part, causing it to elastically deform and thus releasing the resistance to the locking hook, allowing the locking hook to return to its original position, thereby achieving unlocking.
[0011] Specifically, the locking part and the support part are integrally formed into the structure of the integrated base.
[0012] Specifically, the lock hook is rotatably installed inside the lock housing, and the support part is a protrusion located on the top of the integrated base, with the protrusion facing upward to support the rotating shaft of the lock hook.
[0013] Specifically, the locking part is a cantilever structure, with its inner end connected to the integrated base and its outer end suspended in the air.
[0014] Specifically, a guide ramp is provided at the top of the outer end of the locking part, and a stop surface is provided at the adjacent position of the guide ramp; the lock hook is provided with a guide arc surface and a locking surface. In the unlocked state, the guide arc surface and the guide ramp surface cooperate to abut against each other. During the process of the lock hook changing from the unlocked posture to the locked posture, the guide arc surface presses downward against the guide ramp surface until the guide arc surface passes the guide ramp surface, and then the locking surface cooperates to abut against the stop surface to restrict the rotation of the lock hook.
[0015] Specifically, the outer end of the locking part extends with an unlocking shaft, which extends to the outside of the integrated base.
[0016] Specifically, the unlocking mechanism includes an unlocking slide, a pusher, and a combination lock assembly. The unlocking slide and the pusher are slidably mounted on the lock housing. The unlocking slide is provided with an unlocking groove, in which the unlocking shaft is embedded. After the correct combination lock assembly is entered, external force can push the pusher and the unlocking slide, causing the unlocking groove to face downwards and press against the unlocking shaft.
[0017] The beneficial effects of this utility model are:
[0018] This utility model discloses a modular bag lock that is easy to assemble. Compared with the prior art, the structure for supporting the lock hook and the structure for locking by abutting against the lock hook are integrated on the integrated base. The modular structure facilitates assembly, reduces manufacturing difficulty and cost; and the integrated base has strong adaptability and compatibility for locks of different specifications.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0032] This embodiment presents a modular, easy-to-assemble bag lock, such as... Figures 1 to 6 As shown, it includes a lock housing 1, a lock hole located in the lock housing 1, and a lock hook 2 located inside the lock housing 1 at the corresponding position of the lock hole for engaging with a zipper.
[0033] The lock housing 1 is also provided with an integrated base 3. The integrated base 3 includes a locking part 31 for abutting against the lock hook 2 to achieve locking and a support part 35 for supporting the lock hook 2. The locking part 31 is an elastic structure that can swing up and down. The locking part 31 and the support part 35 are integrally formed in the integrated base 3, which is injection molded or cast and milled.
[0034] During the locking process, the locking hook 2 is squeezed, causing the locking part 31 to elastically deform and pass over the locking part 31. Then the locking part 31 rebounds and pushes against the locking hook 2, preventing the locking hook 2 from returning to its original position, thereby achieving locking.
[0035] The device includes an unlocking mechanism 4. During the unlocking process, the unlocking mechanism 4 compresses the locking part 31, causing it to elastically deform and release the resistance to the locking hook 2, allowing the locking hook 2 to return to its original position, thereby achieving unlocking.
[0036] Specifically, the lock hook 2 is rotatably installed inside the lock housing 1, and the support part 35 is a protruding post located on the top of the integrated base 3, which supports the rotating shaft of the lock hook 2. A torsion spring is provided at the lock hook 2, and after the locking part 31 releases the restriction on the lock hook 2, the lock hook 2 automatically rotates to the unlocked position.
[0037] Specifically, the locking part 31 is a cantilever structure, with its inner end connected to the integrated base 3 and its outer end suspended.
[0038] Specifically, a guide slope 32 is provided at the top of the outer end of the locking part 31, and a stop surface 33 is provided at the adjacent position of the guide slope 32; the lock hook 2 is provided with a guide arc surface 21 and a locking surface 22. In the unlocked state, the guide arc surface 21 and the guide slope 32 cooperate to abut against each other. During the process of the lock hook 2 changing from the unlocked posture to the locked posture, the guide arc surface 21 presses downward against the guide slope 32 until the guide arc surface 21 passes the guide slope 32, and then the locking surface 22 cooperates to abut against the stop surface 33 to restrict the rotation of the lock hook 2.
[0039] Specifically, the outer end of the locking part 31 extends an unlocking shaft 34, which extends to the outside of the integrated base 3.
[0040] Specifically, the unlocking mechanism 4 includes an unlocking slide 41, a pusher 42, and a password component 43. The unlocking slide 41 and the pusher 42 are slidably mounted on the lock housing 1. The unlocking slide 41 is provided with an unlocking groove 411, and the unlocking shaft 34 is embedded in the unlocking groove 411. After the correct password is entered into the password component 43, external force can push the pusher 42 and the unlocking slide 41, so that the unlocking groove 411 faces downward and abuts against the unlocking shaft 34. The stop surface 33 of the locking part 31 no longer abuts against the locking surface 22 of the lock hook 2, and the lock hook 2 can be rotated to unlock.
