SUMMARY

[0003] The utility model solves the technical problems that: provide a kind of luggage zipper locks with the advantage that zipper head cannot be inserted when lock cylinder locks, not prone to failure.

[0004] In order to solve the above technical problems, the utility model discloses the following technical scheme: a luggage zipper lock, including casing and lock body, the lock body is installed in the casing, and the lock body includes zipper head, lock hook and lock group, the lock hook includes hook head and lock head, and the hook head is matched with the zipper head, and the lock group includes lock core, lock button and lock spring, the lock core is matched with the lock button, and the lock core is opened and closed, and the lock button is in the opening position and the locking state, the lock button below is equipped with sliding block, the sliding block is equipped with the slot, and the sliding block is matched with the lock core, when the lock core is locked, the sliding block is restricted to remove, when the lock core is opened, the lock button is pushed and moves the sliding block, the lock spring includes fixed part, upper inclined part, lock mouth and opening part, the fixed part is fixed on the casing, the upper inclined part upper end is fixed on the fixed part and extends to the lock mouth to the lock hook position obliquely downwards, the lock mouth is matched with the lock head of the lock hook, and the lock head is restricted to move upwards, the opening part is below the lock mouth, and the lower end of the opening part is inserted into the slot of the lock button, when the lock button is in the opening position, the slot drives the lower end of the opening part and the lock mouth to move away from the corresponding lock hook direction, makes the lock mouth upper side to be separated from the cooperation of the lock head, when the lock button is in the locking position and the zipper head is not inserted into the lock hook, the slot restricts the lower end of the opening part and the lock spring to move away from the corresponding lock hook direction, and the upper inclined part restricts the lock head to turn downwards.

[0005] The utility model discloses the beneficial effect is: through the cooperation of lock spring and lock hook, when the zipper head is inserted into the lock hook, the lock head of the lock hook is contacted first with the upper inclined part of the lock spring when the zipper head pushes, continues to extrude the upper inclined part of the lock spring and makes it move away from the lock hook direction, in this process, the lock core needs to be in the opening state, and the sliding block moves together with the lock spring, until the upper surface of the lock head is lower than the upper end surface of the lock mouth of the lock spring, the lock head no longer has the force to the upper inclined part, and the lock button and the sliding block are restored to the initial state under the action of the elastic restoring force, so that the upper end of the lock mouth of the lock spring and the lock head of the lock hook form the abutment cooperation, and the lock head is restricted to move upwards, in this process, the hook head of the lock hook just turns over to the position matched with the zipper head, and the effect of locking the zipper head is achieved, when the lock needs to be opened, the lock core is opened, and the lock button is in the opening state, and the lock core no longer restricts the lock button, at this moment, the lock button is pushed and drives the sliding block to move away from the lock hook direction, in this process, the fixed part of the lock spring is fixed on the casing and keeps unmoved, the slot on the sliding block and the lower end of the opening part of the lock spring are matched, the lock mouth of the lock spring also moves away from the lock hook direction, until the upper end of the lock mouth is separated from the cooperation of the upper end of the lock head, and the restriction to the lock head turning upwards is removed, at this moment, only needs to adopt the common torsional spring to provide the lock hook with the force of turning upwards, can make the lock head turn upwards and push the zipper head out of the lock body, so that the effect of unlocking is achieved, and when the lock core is in the locking state, the zipper head is inserted into the lock body downwards, the zipper head will contact the upper end of the lock head first, and the upper end of the lock head is extruded and turned over downwards, the lower end of the lock head abuts on the upper inclined part of the lock spring, and the upper inclined part restricts the lock hook to turn over downwards, so that the zipper head can only be inserted into the lock when the lock core is opened.

[0006] Furthermore, the lock cylinder includes a combination lock cylinder and a customs lock cylinder. The combination lock cylinder is engaged with a lock button via a lock rod. The lower end of the customs lock cylinder is provided with a long strip-shaped lever with rounded ends. The slider has a groove, and the lever engages with the groove. When the lock cylinder is locked, the slider is restricted from moving. When the combination lock cylinder is opened, the lock button is pushed to move the slider to open. When the customs lock cylinder is opened, the lever rotates and engages with the groove to move the slider to open. This structure can be applied to dual-channel customs locks, achieving the effect of both combination lock opening and customs lock opening. Attached Figure Description
