Description

Technical Field

[0001] The present invention relates to the technical field of luggage locks, and in particular to a zipper luggage lock. Background Art

[0002] With the need for people to 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 in luggage for easy carrying. Therefore, the safety and anti-theft of luggage are becoming more and more important to people, and luggage locks have become an indispensable component of luggage.

[0003] In the prior art, luggage locks include a hook for locking the zipper pull on the opening and closing side of a luggage. The lock also includes an operating member (which can be replaced by a push button, knob, etc.), a locking mechanism, and a transmission member. The locking mechanism can be a combination lock, key lock cylinder, or NFC. The operating member's restriction can only be released when the locking mechanism's password is correct, the correct key is inserted and turned, or a near-field electronic control sensor is triggered. The operating member drives the hook to move via the transmission member, releasing the lock from the zipper pull, thereby unlocking the luggage.

[0004] The key lock cylinder of a luggage lock generally has a shift block at the bottom of the key lock cylinder that rotates with the lock core. The rotation of the shift block can drive the transmission block, releasing the restriction on the lock hook, and then releasing the zipper pull to unlock. However, in the existing key lock cylinder unlocking structure, if the key needs to be removed, the lock cylinder must be turned back to the locked position before the key can be removed. However, after the key is removed, the lock hook automatically returns to the locked position. To insert the zipper pull, the key must be inserted and the lock cylinder turned again. However, in some use cases, it is necessary to keep the lock hook in the unlocked position after the key is removed so that the zipper pull can be inserted and locked without the key. Existing locks cannot meet these requirements. Summary of the Invention

[0005] In view of the above technical problems in the prior art, the present invention provides a zipper luggage lock.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] Provided is a zipper luggage lock, comprising a lock housing, a lock hook, a key lock cylinder, and a limiting member. The lock housing is provided with a lock hole for inserting a zipper head. The lock hook is movably mounted in the lock housing and corresponds to the lock hole to clamp the inserted zipper head. The lock hook is restricted by the limiting member and locked.

[0008] In the locked state, after inserting the correct key, external force operation to rotate the key lock cylinder can move the limiter from the locked position to the unlocked position to release the restriction on the lock hook. The external force operation commands the lock hook to move from the locked position to the unlocked position to release the zipper slider. The characteristic is that: in the locking direction, the reset of the key lock cylinder is independent of the reset of the limiter.

[0009] The lock housing is also provided with a spring piece located below the lock hook for elastically pressing the zipper head outward. The lock hook is provided with a blocking part. After the key is unlocked and the zipper head pops out, the spring piece presses against the blocking part and prevents the lock hook from returning to the locked position from the unlocked position; when the zipper head is inserted from the keyhole, the spring piece can be pushed away from the blocking part, so that the lock hook is freed from the obstruction and returned to the locked position.

[0010] Specifically, there are two locking hooks, and the elastic piece is provided with a first bent portion and a second bent portion facing outwards against the two locking hooks.

[0011] Specifically, the lock hook is slidably installed in the lock housing, and the lock housing is provided with a first spring that applies force to the lock hook so that the lock hook maintains a tendency to move toward the locked position; the lock housing is also provided with an operating member extending outside the lock housing, and the operating member is linked to the lock hook.

[0012] Specifically, the limiting member includes a rotating block and a linkage block. The rotating block is rotatably mounted in the lock housing. A limiting portion is provided on the circumference of the rotating block. The linkage block is slidably mounted in the lock housing. A shift block is provided at the bottom of the key lock cylinder.

[0013] In the locked state, the limit part presses against the lock hook to restrict its sliding; when the key is unlocked, turning the key lock cylinder can make the shift block drive the linkage block to slide, and then drive the rotating block to rotate, so that the limit part and the lock hook are staggered and unlocked; the lock housing is provided with a second spring that applies force to the rotating block to keep the rotating block returning to the tendency to press against the lock hook.

[0014] Specifically, a driving portion separated from the limiting portion is further provided on the peripheral side of the rotating block, and the linkage member is provided with a linkage groove, in which the driving portion is embedded, so that when the linkage member slides, the rotating block is driven to rotate via the driving portion.

[0015] Specifically, the linkage part is provided with an open groove, and the shift block is located in the open groove. When unlocking, the shift block presses against the groove wall of the open groove to drive the linkage part. When the key lock cylinder is reset, the shift block moves along the groove direction of the open groove, thereby preventing the linkage part from following the key lock cylinder to reset.

[0016] Specifically, one of the linkage member and the lock housing is provided with a positioning tooth, and the other is provided with two positioning grooves. In the unlocked position, the positioning tooth is embedded in one of the positioning grooves, and in the locked position, the positioning tooth is embedded in the other positioning groove.

[0017] Specifically, the blocking portion is a protruding structure integrally formed on the locking hook.

[0018] Specifically, it also includes a password component, which includes a password wheel and an unlocking piece. A password unlocking part is also provided on the peripheral side of the rotating block. After the password wheel rotates to the correct password, the restriction on the unlocking piece is released. The unlocking piece drives the password unlocking part to drive the rotating block to rotate, so that the limit part and the lock hook are staggered and unlocked.

[0019] Specifically, a third spring is provided in the lock housing to apply force to the unlocking member, so that the unlocking member maintains a tendency to move in the unlocking direction.

[0020] Beneficial effects of the present invention:

[0021] Compared with the prior art, the zipper luggage lock of the present invention has the advantages that, in the locking direction, the resetting of the key lock cylinder and the resetting of the limit member are independent, so the resetting of the key lock cylinder will not cause the limit member to be reset, thereby providing a basis for the lock hook to remain in the unlocked position; due to the provision of a blocking portion of the spring piece and the lock hook, after the key is unlocked and the zipper head pops out, the spring piece abuts against the blocking portion and prevents the lock hook from resetting from the unlocked position to the locked position, so that the zipper head can still be inserted into the keyhole and cooperate with the lock hook; when the zipper head is inserted from the keyhole, it can push the spring piece and the blocking portion to be offset, so that the lock hook is freed from the obstruction and resets to the locked position, thereby achieving locking.

[0035] The present invention is described in detail below with reference to specific embodiments and accompanying drawings.

[0036] A zipper luggage lock of this embodiment, such as Figures 1 to 5 As shown, the lock comprises a lock housing 1, a lock hook 2, a key lock cylinder 3, and a limiter 4. The lock housing 1 is provided with a lock hole 11 for inserting a zipper pull. Two lock hooks 2 are slidably mounted in the lock housing 1, and their hook portions 21 correspond to the lock hole 11, for clamping the inserted zipper pull. The lock housing 1 is provided with a first spring 51 that applies force to the lock hook 2 to keep the lock hook 2 moving toward the locked position. The lock housing 1 is also provided with a pusher 12 that extends outside the lock housing 1 as an operating member. The pusher 12 is linked to the lock hook 2. In the unlocked state, human power overcomes the force of the first spring 51 and presses the pusher 12, which can drive the lock hook 2 to slide and release the restraint on the zipper pull.

[0037] In this embodiment, the limiter 4 includes a rotating block 41 and a linkage block 42. The rotating block 41 is cylindrical and can be rotatably installed in the lock housing 1. A limiting portion 411 is provided on the circumferential side of the rotating block 41. The linkage block 42 can be slidably installed in the lock housing 1. A shift block 31 is provided at the bottom of the key lock cylinder 3. Figure 3 In the locked state shown, the limiter 411 abuts against the end of the lock hook 2 to restrict its sliding; the lock housing 1 is provided with a second spring 52 that applies force to the rotating block 41, so that the rotating block 41 maintains the tendency to return to abut against the lock hook 2. When the key is unlocked, after inserting the correct key, external force can be used to rotate the key lock cylinder 3 to cause the shift block 31 to drive the linkage block 42 to slide, thereby driving the rotating block 41 to rotate, so that the limiter 411 and the lock hook 2 are offset, thereby releasing the restriction on the lock hook 2. External force is used to press the push button 12 to move the lock hook 2 from the locked position to the unlocked position to release the zipper head. Figure 4 In the unlocked state shown, the end of the lock hook 2 blocks the limit portion 411 in the circumferential direction of the rotating block 41, so that the rotating block 41 cannot be rotated and reset. Only when the lock hook 2 slides completely back to the locked position can the rotating block 41 be reset under the action of the second spring 52.

[0038] Specifically, a driving portion 412 is provided on the circumferential side of the rotating block 41, which is separated from the limiting portion 411. The linkage member is provided with a long linkage groove 421, and the driving portion 412 is embedded in the linkage groove 421, so that when the linkage member slides, the rotating block 41 is driven to rotate via the driving portion 412.

[0039] Specifically, in the locking direction, the resetting of the key lock cylinder 3 is independent of the resetting of the limit member 4, which is specifically achieved as follows: the linkage member is provided with an opening groove 422, and the shift block 31 is located in the opening groove 422. When unlocking, the shift block 31 presses against the groove wall of the opening groove 422 and drives the linkage member to slide. When the key lock cylinder 3 is reset, the shift block 31 moves along the notch direction of the opening groove 422, thereby ensuring that the linkage member does not follow the key lock cylinder 3 to reset.

[0040] Specifically, the lock housing 1 is provided with a positioning tooth 13, and the linkage part is provided with two positioning grooves 423. In the unlocking position, the positioning tooth 13 is embedded in one of the positioning grooves 423, and in the locking position, the positioning tooth 13 is embedded in the other positioning groove 423, so as to facilitate the linkage part to accurately move and position in the unlocking and locking positions.

[0041] The core improvement of this embodiment is that the lock housing 1 is further provided with a spring plate 6 located below the lock hook 2 for elastically pressing the zipper slider outward. The lock hook 2 is provided with a blocking portion 22, which is a protruding structure integrally formed with the lock hook 2. After the key is unlocked and the zipper slider is ejected, the spring plate 6 presses against the blocking portion 22, preventing the lock hook 2 from returning to the locked position from the unlocked position. In other words, the lock hook 2 is not fully returned to the locked position, so the zipper slider is still not blocked by the hook portion 21 of the lock hook 2 and can be inserted through the keyhole 11. When the zipper slider is inserted inward from the keyhole 11, the spring plate 6 is pushed away from the blocking portion 22, allowing the lock hook 2 to return to the locked position and engage the zipper slider. In this way, the end of the lock hook 2 is staggered circumferentially with respect to the rotating block 41. Under the action of the second spring 52, the limiting portion 411 of the rotating block 41 resumes blocking the end of the lock hook 2, and the driving portion 412 of the rotating block 41 simultaneously drives the linkage member to return to the locked position.

[0042] In this embodiment, the elastic piece 6 is provided with a first bent portion 61 and a second bent portion 62 facing outwards against the two locking hooks 2 .

[0043] This embodiment also includes a password assembly 7, which includes a password wheel 71 and an unlocking member 72 slidably mounted within the lock housing 1. A password unlocking portion 413 is also provided on the circumference of the rotating block 41. The password unlocking portion 413, the limiting portion 411, and the driving portion 412 are spaced apart and distributed around the circumference of the rotating block 41. When the password wheel 71 rotates to the correct password, the unlocking member 72 is released. The unlocking member 72 drives the password unlocking portion 413, which in turn drives the rotating block 41 to rotate, causing the limiting portion 411 to shift away from the lock hook 2, thereby unlocking the lock. Specifically, a third spring 53 is provided within the lock housing 1 to apply force to the unlocking member 72, ensuring that the unlocking member 72 maintains its tendency to move in the unlocking direction. When the password is correct, the rotating block 41 is automatically driven to rotate and unlock.
