Description

Technical Field

[0001] The invention relates to a double-channel buckle lock for a suitcase. Background Art

[0002] As the appearance design of suitcases has become more and more important, more and more short and wide vertical lock designs have appeared to replace the traditional long and narrow horizontal side lock lock design. However, new disadvantages have also emerged. The traditional iron hook structure has been cancelled for the sake of aesthetics, resulting in insufficient strength of the lock and insufficient vertical closing force on the suitcase, resulting in a gap between the upper and lower suitcases, the suitcase is not closed tightly, and it is even easy for the suitcase to open without being locked. Especially in the locks with dual-channel functions, the traditional structure is relatively complex and has the defect of being prone to failure. Summary of the Invention

[0003] The invention provides a double-channel buckle lock for a suitcase, which has the advantages of simple structure, tight closure, strong strength and reliability.

[0004] The lock rod is provided with a lock head, and the lock head cooperates with the lock groove to lock the lock buckle springboard on the lower lock body. The lock rod is provided with a lock hole and a lock top block. The protrusion, the customs lock includes a customs lock core and a customs lock block, the customs lock block is located at the lower end of the customs lock core and rotates with the customs lock core, the customs lock block is inserted into the lock hole and drives the lock rod to move up and down along the direction of cooperation between the lock head and the lock slot, the password lock includes a password lock core and a password lock rod, one end of the password lock rod is connected to the lower lock body, the other end of the password lock rod is a suspended end, and the suspended end is provided with a password lock head. When the password lock core is locked, the password lock rod is restricted from flipping up and down around the connection point on the lower lock body, and the password lock head is flipped up and down with the password lock rod, and the password lock head cooperates with the button, and restricts the button from moving inward when the password lock core is locked. The button is provided with a button bevel, and the two sides of the lock protrusion are inclined surfaces, and the button bevel cooperates with the lock protrusion. When the button is pressed inward, the lock rod is driven to move upward and disengage from the lock slot through the cooperation of the button bevel and the lock protrusion.

[0005] The beneficial effect of the present invention is that, through the downward flipping of the lock springboard and the cooperation between the lock push head and the lock top block, the lock push head of the upper lock body fixed on the upper box body and the lock top block of the lower lock body fixed on the lower box body respectively, in the process of closing the lock springboard downward, the lock push head applies an upward thrust to the lock top block, and the thrust is composed of a lock springboard hinged on the upper lock body and a lock push head hinged on the lock springboard. The connecting rod structure has a certain angle from the lock springboard in the open state to the lock springboard flatly covering the lock downward in the locked state. The lock is locked and unlocked when the lock is unlocked, and the lock is unlocked when the lock is unlocked. The combination lock head at one end of the combination lock rod moves upward to the position where the restriction button is released to move inward. At this time, the button is pushed inward again, and the button bevel on the button cooperates with the bevels on both sides of the lock protrusion on the lock rod to push the lock rod upward, so that the lock head of the lock rod disengages from the lock slot, thereby releasing the restriction on the lock buckle springboard to flip upward and achieve the purpose of unlocking the buckle. When the buckle needs to be locked, it is only necessary to flip the lock buckle springboard downward to cover it flat, and then lock the combination lock cylinder, which drives the combination lock rod to flip downward and drives the combination lock head to move downward back to the restriction button. When the lock needs to be locked, the lock plate only needs to be flipped down and flat, and the customs lock core is turned back at the same time to drive the locking rod downward so that the lock head can be engaged with the lock slot again.

[0006] Furthermore, the upper lock body is provided with a guide groove, and the lower lock body is provided with a guide boss, and the guide boss is inserted into and cooperates with the guide groove. The provision of the guide boss and the guide groove can make the upper lock body and the lower lock body more accurately positioned during the closing process and close more tightly, and will not cause left and right deviations when the upper and lower box bodies are closed.
