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 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 turning 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, and the connecting rod structure has a certain angle from the lock springboard in the open state to the lock springboard covering the bottom flat state. The process of zero angle in the locked state, during which the upper box body and the lower box body are pulled together, and the pulling force can only be released when the lock springboard flips upward again, and the pulling force is at a vertical angle to the flipping of the lock springboard. Therefore, the cooperation between the lock rod and the lock slot that restricts the upward flipping of the lock springboard will not withstand much force. When the suitcase needs to be opened, one way is to open it through the combination lock. You only need to accurately open the combination lock cylinder with the combination lock cylinder to release the restriction on the combination lock rod. Under the action of the return spring, the combination lock rod drives the combination lock head around its hinge point. When the lock is unlocked, the combination lock head is rotated to the position where the restriction button is released and moved 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, pushing the lock rod upward to disengage the lock head from the lock groove, thereby releasing the restriction on the lock buckle springboard to flip upward and achieve the purpose of unlocking the lock. When the lock needs to be locked, it is only necessary to flip the lock buckle springboard downward to cover it flat, and at the same time lock the combination lock cylinder, driving the combination lock rod to move horizontally and driving the combination lock head to rotate around its hinge point back to the position where the restriction button is moved inward. When the lock needs to be locked, the lock block only needs to be turned downward to cover the position, and the customs lock cylinder needs to be turned back at the same time to drive the lock rod downward so that the lock head can be engaged with the lock groove 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.
