Description

Technical Field

[0001] This utility model relates to the field of luggage lock technology, and in particular to a resilient reset luggage lock. Background Technology

[0002] Bags are a type of storage container. People often use bags to store loose items in their daily lives. In today's society where living standards are constantly improving, the demand for bags is increasing.

[0003] To keep bags closed and prevent items from falling out, locks are typically installed on them. Some bags use bolt-type locks to connect the bag lid and the bag body. A bolt-type lock includes a bolt pivotally connecting the bag body and a connecting seat on the lid. The connecting seat has a through hole that matches the bolt, penetrating the lid. To connect the lid and bag body with a bolt-type lock, first rotate the bolt so that its axis is parallel to the direction of the through hole. Then, bring the connecting seat close to the bolt so that the through hole aligns with the bolt. Next, pass the bolt through the through hole. Finally, rotate the bolt until its axis is perpendicular to the direction of the through hole. The connection between the lid and bag body is now complete. As can be seen, the operation of connecting the lid and bag body with a bolt-type lock is relatively cumbersome and inconvenient. Therefore, developing a simple and convenient bag lock is an urgent problem to be solved.

[0004] Chinese patent CN210067707U discloses a snap-fit ​​bag lock, including a mounting base, a slider, a pusher connecting one end of the slider, an elastic reset member linking the slider and the pusher, a mounting assembly for connecting a bag cover, and a plug rod disposed on the mounting assembly. The slider has a communicating receiving cavity and a first insertion port. The slider slides within the receiving cavity, and the end of the slider away from the pusher has a second insertion port corresponding to the first insertion port. When the elastic reset member is in its original state, the second insertion port is located between the pusher and the first insertion port. The slider has a locking protrusion located within the first insertion port, and the locking protrusion is located on the side of the second insertion port away from the pusher. The end of the pusher away from the slider is located outside the mounting base. The plug rod is disposed corresponding to the first insertion port, and a locking groove is provided on the plug rod corresponding to the locking protrusion. This snap-fit ​​bag lock is simple and convenient to operate, but its structure is complex, with many parts, slow assembly, reduced production efficiency, and high production costs.

The lock body 10 is provided with a lock hole 12 in the middle, and the lock hole 12 communicates with the receiving cavity 11. A side opening 13 is provided on one side of the lock body 10, and the side opening 13 communicates with the receiving cavity 11. A rear limiting groove 14 is provided at the end of the lock body 10 away from the side opening 13, and the rear limiting groove 14 communicates with the receiving cavity 11. The lock body 10 is provided with a guide block 15, and the guide block 15 is arranged adjacent to the lock hole 12.

[0041] Please see Figure 1 and Figure 2The sliding hook 20 is slidably disposed within the receiving cavity 11. The sliding hook 20 is provided with a guide groove 21 and a latching block 22. The latching block 22 is disposed adjacent to the guide groove 21. The guide block 15 extends into the guide groove 21. A pressing block 23 is integrally connected to the end of the sliding hook 20 away from the latching block 22. The pressing block 23 extends out of the lock body 10 through the side opening 13. The sliding hook 20 is provided with a front limiting groove 24. There are two front limiting grooves 24, which are respectively disposed at both ends of the latching block 22. One end of the elastic member 30 abuts against the bottom of the rear limiting groove 14, and the other end of the elastic member 30 abuts against the bottom of the front limiting groove 24. The front limiting groove 24, the rear limiting groove 14, and the elastic member 30 correspond one-to-one. The sliding hook 20 is provided with sliding pads 25 at both the upper and lower ends. The sliding pads 25 can effectively reduce the friction between the sliding hook 20 and the lock body 10, making the sliding hook 20 slide more smoothly and effectively improving the working stability of the sliding hook 20.

[0044] Please see Figure 4 The latch 50 also includes a crash pin 56, and the push part 54 is provided with a fixing hole in the axial direction, into which the crash pin 56 is inserted.

[0045] The working principle of the elastic reset bag lock 100 in this embodiment is as follows: The lock body 10 is fixed on the bag cover, and the buckle 50 is fixed on the bag body. When the bag cover and the bag body are locked, the pushing part 54 passes through the lock hole 12 and the guide groove 21 extends into the through hole 43. During this process, the pushing arc surface 541 pushes the buckle block 22 to drive the sliding lock hook 20 to move away from the side opening 13 until the buckle block 22 is engaged in the slot 55. During the process of the buckle block 22 being engaged in the slot 55, the sliding lock hook 20 is reset under the action of the elastic element 30 so that the buckle 50 is locked with the lock body 10.

[0046] When unlocking the bag flap and body, press the block 23 with your hand to drive the sliding lock hook 20 to move away from the side opening 13 until the buckle block 22 comes out of the slot 55, and then let the push part 54 come out of the lock body 10 to unlock the bag flap and body.

[0047] The beneficial effects of this utility model are as follows: With the cooperation of the lock body 10, sliding lock hook 20, elastic element 30, lock cover 40 and lock buckle 50, when locking, it is only necessary to let the pushing part 54 pass through the lock hole 12, the guide groove 21 extend into the through hole 43, and the buckle block 22 snap into the buckle groove 55. When unlocking, it is only necessary to press the pressing block 23 by hand to drive the sliding lock hook 20 to move away from the side opening 13 until the buckle block 22 is dislodged from the buckle groove 55, and then let the pushing part 54 dislodged from the lock body 10. The operation is simple, there are few parts, it is easier to assemble, effectively improves assembly efficiency, increases production efficiency, and reduces production costs.
