Description

Technical Field

[0001] The invention relates to a double-channel luggage zipper password lock. Background Art

[0002] The invention patent with the patent number of 201720041992.1 discloses a luggage zipper password lock, including a shell, a password lock group, a lock body switch, two lock holes, two zipper lock hooks and two springs are arranged in the shell, the upper end of the zipper lock hook is tilted downward in the locking direction of the zipper lock hook to form a transition slope, the lock body switch includes a switch button and a lock rod, the switch button and the lock rod are an integrally formed structure, the password lock group cooperates with the lock rod to control the opening and locking of the lock body switch, the two zipper lock hooks are The two spring sheets are arranged on the locking rod and move with the locking rod, and the two spring sheets are respectively arranged at the front ends of the locking directions of the two zipper hooks, and the spring sheet includes an inclined portion and a horizontal portion. The zipper hook includes a lower hook surface, and the lower end of the inclined portion is located below the lower hook surface and is fixed on the locking rod, and the upper end of the inclined portion is inclined upward in the locking direction of the zipper hook and exceeds the lower hook surface of the zipper hook, and the horizontal portion is connected to the uppermost end of the inclined portion and extends in the locking direction of the zipper hook. Since the positions of the two locking holes on the shell are fixed, and And the width of the lock hole is obviously larger than the thickness of the zipper head. When the second zipper head is locked in, the first zipper head should still be in the locking triangle space formed by the spring and the zipper lock hook. However, in actual use, if the thickness of the zipper head is too different from the width of the lock hole, the zipper head will be too loose and easily pulled out in the locked state. Therefore, considering the locking firmness, the width of the lock hole can only be designed to be slightly larger than the thickness of the zipper head. When the zipper head is locked, there is usually a large instantaneous thrust to squeeze the zipper open. The zipper hook is easily moved too far in the opening direction when the second zipper head is locked. The existing spring pieces are inclined parts except the horizontal part. The elastic force of the spring pieces is mainly manifested in the elastic restoring force of the inclined part after the arc bending under pressure. After the restoring force is decomposed into horizontal and vertical forces, the horizontal force is obviously smaller than the vertical force. Therefore, when the second zipper head is locked, the first zipper head is easily ejected from the zipper hook, and such repeated ejection affects the use. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a double-channel luggage zipper password lock which has the advantages of simple structure, good firmness and not prone to failure.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: a double-channel luggage zipper password lock, comprising a shell and a lock body, the lock body is installed in the shell, the lock body comprises a zipper head, a lock hook and a lock group, the lock hook comprises a hook head and a lock head, the hook head cooperates with the zipper head, the lock group comprises a lock core, a lock button and a lock spring, the lock core cooperates with the lock button, the opening and closing of the lock core corresponds to the lock button being in the open position and the locked state, a slider is provided under the lock button, a slot and a "heart"-shaped pull groove are provided on the slider, the slider cooperates with the lock core, the lock core comprises a password lock core and a customs lock core, the password lock core is abutted and cooperated with the lock button through a lock rod, a long strip pull block with arc-shaped ends is provided at the lower end of the customs lock core, the pull block and the "heart"-shaped pull groove are connected to each other, and the lock core is locked. The groove cooperates with each other. When the lock cylinder is locked, the movement of the slider is restricted. When the password lock cylinder is opened, the lock button is pushed to drive the slider to move and open. When the customs lock cylinder is opened, the dial block rotates and drives the slider to move and open through cooperation with the "heart"-shaped dial groove. The lock spring includes a fixed part, an upper inclined part, a locking part and an opening part. The fixed part is fixed on the shell, the upper end of the upper inclined part is fixed on the fixed part, and extends obliquely downward to the corresponding lock hook position to the locking part. The locking part cooperates with the lock head of the lock hook to limit the lock head from moving upward. The opening part is located below the locking part, and the lower end of the opening part is inserted into the slot of the lock button. When the slider is in the open position, the slot drives the lower end of the opening part and the locking part to move away from the corresponding lock hook, so that the locking part is out of cooperation with the lock head.

[0005] The beneficial effect of the present invention is that through the cooperation of the lock spring and the lock hook, when the zipper head is stuck in the lock hook, the zipper head pushes the lock head of the lock hook to contact the upper inclined part of the lock spring first, and then continues to squeeze the upper inclined part of the lock spring downward to deform it in the direction away from the lock hook, until the upper surface of the lock head is lower than the lower surface of the locking part of the lock spring, and the lock head no longer has an acting force on the upper inclined part. At this time, the upper inclined part of the lock spring returns to its initial state under the action of the elastic restoring force, so that the locking part of the lock spring and the lock head of the lock hook form an abutment cooperation, restricting the lock head from moving upward. In this process, the hook head of the lock hook just flips over to a position cooperating with the zipper head, achieving the effect of locking the zipper head; and when the password is needed to unlock, the password lock core is opened, and the lock rod can move in the direction away from the lock hook, thereby releasing the abutment restriction on the lock button. The lock button is in the open state, and the lock core has no restriction on the lock button. At this time, the lock button is pushed and drives the slider to move in the direction away from the lock hook. In this process The fixed part of the middle lock spring is fixed on the shell and remains motionless. The slot on the slider cooperates with the lower end of the opening part of the lock spring, driving the locking part of the lock spring to move in the direction away from the lock hook until the lower surface of the lock part disengages from the cooperation on the upper surface of the lock head, releasing the restriction on the lock head flipping upward. At this time, it is only necessary to use the commonly used torsion spring to provide an upward flipping force to the lock hook, so that the lock head can be flipped upward and the zipper head can be pushed out of the lock body, thereby achieving the effect of unlocking; when the customs lock needs to be unlocked, the customs lock cylinder is opened, and the customs lock cylinder is rotated to drive the dial block, and the long strip dial block cooperates with the "heart"-shaped dial groove on the slider to drive the slider to move in the direction away from the lock hook, and the unlocking effect is also achieved. The double-channel luggage zipper password lock with this structure has high reliability and is not easy to fail. It has a simple structure and is easy to use. It has high firmness. In the locked state, the zipper head is forcibly pulled, and the upper oblique part extending obliquely downward will only make the lock spring tighter and tighter. BRIEF DESCRIPTION OF THE DRAWINGS
