Description

Technical Field

[0001] The utility model relates to the technical field of luggage locks, in particular to a luggage lock with a secondary stop function. Background Art

[0002] With the needs of people's travel for work, tourism, business trips, etc., various types of luggage have occupied an increasingly important position in people's lives. People often put some valuables and documents into the luggage for easy carrying. Therefore, the safety and anti-theft of luggage have attracted more and more attention, and luggage locks have become an indispensable part of luggage.

[0003] In the prior art, a luggage lock includes a locking assembly, which includes a lock catch part and a lock hook respectively installed on two opening and closing sides of the luggage, and the two are mutually latched and locked. The luggage lock also includes an operating member (which can be replaced by a push type, a button, a knob, etc.), a locking mechanism and a transmission member. The locking mechanism is a password lock, a key lock cylinder or NFC. After the password unlocking of the locking mechanism or the correct key is inserted and rotated or the near-field electric control induction is triggered, the restriction of the operating member can be released. The operating member drives the lock catch part to rotate or slide via the transmission member, and unlocks with the lock hook to achieve unlocking.

[0004] For the key lock cylinder of a luggage lock, generally, a rotating dial block is arranged at the bottom of the lock cylinder, and after rotation, the restriction on the lock hook is released to achieve unlocking. This means that to pull out the key, the lock cylinder must be rotated back to the locked position before the key can be pulled out. However, in some usage scenarios, it is required that after the key is pulled out, the lock catch part can remain in the unlocked position so that the lock hook can be inserted to lock without a key. Traditional locks cannot meet the above requirements.

[0005] Therefore, the inventor has developed a luggage lock with flexible use as disclosed in the Chinese patent document with the publication number of CN221169096U, which includes a lock body and a lock hook. The lock body includes a lock shell, a lock catch, a key lock cylinder and a limiting member. The lock catch and the limiting member are movably installed on the lock shell. The lock hook can be inserted into the lock shell and latched with the lock catch. The lock catch is locked by being restricted by the limiting member. By externally operating and rotating the key lock cylinder, the limiting member can be moved from the locked position to the unlocked position to release the restriction on the lock catch and unlock. In the unlocking direction, the key lock cylinder can toggle the limiting member. In the locking direction, the reset of the key lock cylinder and the reset of the limiting member are independent of each other. A stop member is also arranged in the lock shell. When the limiting member moves to the unlocked position, the stop member automatically catches the limiting member to keep the lock catch in the unlocked position, and the key lock cylinder can be reset to pull out the key. When the lock hook is inserted into the lock body, it can overcome the acting force of the stop member and drive the limiting member to the locked position, and the lock hook can also be inserted to lock without a key.

[0006] In further use, it is found that after the lock hook is inserted into the lock body, the limiting member immediately returns to the locked position. After the key is pulled out, although the unlocked state is maintained, it can only be locked once. If you need to unlock again, you need to insert the key again or enter the correct password. Summary of the Invention

[0007] In view of all or part of the above technical problems existing in the prior art, the present invention provides a luggage lock with a secondary stop function.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0046] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0047] The luggage lock of this embodiment, as Figures 1 to 11 shown, includes a lock body 2 and a lock hook 1. The lock body 2 includes a base 21, a lock housing 3, a push-twist 4, a key lock cylinder 5, and a lock block 51. The base 21 is used to be fixed to one opening and closing side of the luggage. The lock housing 3 is hinged to the base 21, and the lock housing 3 can swing relative to the base 21 within a certain angle range. The push-twist 4 is slidably installed in the lock housing 3 with a limited stroke and is partially exposed. The portion of the push-twist 4 located inside the lock housing 3 is provided with a locking portion 41, and the lock housing 3 is provided with a lock hole 31. The lock hook 1 is fixed to the other opening and closing side of the luggage, and the lock hook 1 can be inserted into the lock hole 31 to engage with the locking portion 41. A first spring (not shown in the figure, one end of the first spring abuts against the push-twist 4, and the other end abuts against the lock housing 3) for applying a force to the push-twist 4 is provided inside the lock housing 3, so that the push-twist 4 maintains an outward locking trend. When unlocking, an external force overcomes the acting force of the first spring and presses the push-twist 4 inward to disengage the lock hook 1 from the locking portion 41. A compressed fourth spring (not shown in the figure, one end of the fourth spring abuts against the base 21, and the other end abuts against the bottom of the lock housing 3) is provided between the base 21 and the lock housing 3. After the lock hook 1 is disengaged from the locking portion 41, the lock housing 3 automatically tilts upward relative to the base 21.

[0048] The lock block 51 is rotatably installed in the lock housing 3. An embedded block 6 is slidably provided inside the push-twist 4, and the moving direction of the embedded block 6 is perpendicular to the moving direction of the push-twist 4. A second spring (not shown in the figure, one end of the second spring abuts against the embedded block 6, and the other end abuts against the push-twist 4) for applying a force to the embedded block 6 is provided inside the lock housing 3, so that the embedded block 6 maintains a reset locking trend. As Figure 6 shown, the second spring applies a rightward thrust to the embedded block 6. Two positioning pins 7 arranged side by side at intervals are slidably provided on the embedded block 6. Figures 6 to 11In it, the stop pin 7 can move up and down. The push-twist 4 is provided with a stop hole 42, and the direction in which the stop pin 7 is inserted into the stop hole 42 is parallel to the moving direction of the push-twist 4. An unlocking portion 32 capable of being inserted into the stop hole 42 is provided in the lock housing 3, and the unlocking portion 32 is an unlocking protrusion integrally injection-molded on the lock housing 3.

[0049] As Figure 6 and Figure 7 shown, in the locked state, the embedded block 6 is in the locked position and is blocked by the lock block 51 to restrict the movement of the push-twist 4, and the push-twist 4 cannot be pressed. Therefore, the locking portion 41 of the push-twist 4 remains locked with the lock hook 1. At this time, the stop pin 7 and the stop hole 42 are in a staggered state.

[0050] When unlocking, an external force is used to operate and rotate the key lock cylinder 5 to drive the embedded block 6 to move from the locked position to the unlocked position via the lock block 51, so as to release the restriction of the lock block 51 on the embedded block 6 and unlock, as Figure 8 and Figure 9 shown. At the same time, the stop pin 7 on the left follows the embedded block 6 and moves past the stop hole 42 in the unlocking direction (to the left), and the stop pin 7 on the right is inserted into the stop hole 42 to prevent the embedded block 6 from resetting. After unlocking, the embedded block 6 deviates from the rotation trajectory range of the lock block 51, and the reset of the key lock cylinder 5 and the lock block 51 is independent of the reset of the embedded block 6, that is, the reset of the lock block 51 does not involve the reset of the embedded block 6.

[0051] Figure 8 and Figure 9 shown in the state, the embedded block 6 is no longer abutted and limited by the lock housing 3, so the push-twist 4 can be pressed. However, each time the push-twist 4 is pressed forcefully, it can cause the unlocking portion 32 to push against the stop pin 7 originally inserted in the stop hole 42 to disengage, and the embedded block 6 moves in the locking direction (towards the right) under the action of the second spring, and the next stop pin 7 is inserted into the stop hole 42 to continue to stop the embedded block 6, forming a state as Figure 10 and Figure 11 shown. Until all the stop pins 7 move away from the stop hole 42 to the locking position, the embedded block 6 resets to the locking position.

[0052] In practice, according to the needs of the usage scenario, three or more stop pins 7 can be set in the same way. Each time the push-twist 4 is pressed, the stop pin 7 originally inserted in the stop hole 42 can be disengaged and the next stop pin 7 is inserted, and the embedded block 6 moves one step closer to the locking position, so that the number of times of pressing the push-twist 4 to unlock can be controlled when the key is pulled out after unlocking the key.

[0053] Specifically, the lock block 51 is in the shape of an elongated strip, and the lock block 51 is installed at the bottom of the key lock cylinder 5. The key lock cylinder 5 can drive the lock block 51 to rotate together. The lock block 51 is provided with an elongated hole 511 along the length direction, so that the lock block 51 can slide relative to the key lock cylinder 5. A password assembly 8 is also provided in the lock housing 3, which includes a floating block 81, a plurality of code adjustment wheels 82 and a plurality of code wheels 83. The plurality of code adjustment wheels 83 are rotatably installed in the lock housing 3 and partially exposed. The plurality of code adjustment wheels 82 are correspondingly installed on the inner side of the plurality of code wheels 83 and rotate together with each other. A concave-convex matching structure in the prior art is provided between the code adjustment wheel 82 and the floating block 81. When the password is wrong, the floating block 81 resists the lock block 51; when the password is correct, the floating block 81 moves up and staggers with the lock block 51, and the lock block 51 can move along the length direction to unlock.

[0054] In this embodiment, the push knob 4 is provided with a receiving cavity 43 for the embedded block 6 to slide in a directional manner, and the stop hole 42 is opened on the side wall of the receiving cavity 43. The stop hole 42 satisfies that: the stop pin 7 can pass through the stop hole 42 without being blocked in the unlocking direction, and the stop pin 7 is inserted into the stop hole 42 and clamped in the locking direction. Specifically, it is achieved as follows: the side wall of the stop hole 42 in the locking direction is an inclined wall 421, so that when the embedded block 6 moves in the unlocking direction, the stop pin 7 is not blocked by the wall and crosses the stop hole 42; the side wall of the stop hole 42 in the unlocking direction is a vertical wall 422, so that when the embedded block 6 moves in the locking direction, the stop pin 7 is inserted into the stop hole 42 to prevent the embedded block 6 from resetting to the locked position.

[0055] In this embodiment, the embedded block 6 is provided with a receiving cavity 61 for each stop pin 7 to slide in a directional manner, and the receiving cavity 61 is provided with a third spring (not shown in the figure, one end of the third spring abuts against the stop pin 7, and the other end abuts against the top of the receiving cavity 61) to apply force to the stop pin 7, so that the stop pin 7 is automatically inserted after being aligned with the stop hole 42.

[0056] In this embodiment, the lock hook 1 is provided with a first guide arc surface 11 and a first hooking surface 12, and the lock buckle part 41 is provided with a second guide arc surface 411 and a second hooking surface 412. When the lock hook 1 is inserted into the lock hole 31, the first guide arc surface 11 presses against the second guide inclined surface so that the push button 4 is pressed down until the first guide arc surface 11 is separated from the second guide arc surface 411, and the first hooking surface 12 cooperates with the second hooking surface 412 to lock.
