Description

Double-channel lock catch for suitcase

Technical Field

The invention relates to a double-channel lock catch for a suitcase.

Background

Along with the increasing importance of the appearance design of the suitcase, more and more short and wide vertical buckling designs replace the traditional long and narrow transverse side buckling designs, but new defects are also caused, the traditional iron hook structure is cancelled for attractive appearance, the strength of the buckling is insufficient, the vertical folding force of the suitcase body is insufficient, gaps are reserved between the upper suitcase body and the lower suitcase body, the suitcase is not tightly folded, and even the suitcase is easy to open, especially in the buckling with the double-channel function, the traditional structure is complex, and the defect of easy failure exists.

Disclosure of Invention

The invention provides a double-channel lock catch for a suitcase, which has the advantages of simple structure, tight folding, firm strength and reliability.

In order to solve the technical problems, the invention adopts the following technical scheme: the double-channel lock for suitcase comprises an upper lock body, a lower lock body and a lock catch springboard, wherein the upper lock body is fixed on the upper box body, the lower lock body is fixed on the lower box body, the upper end of the lock catch springboard is hinged on the upper lock body, the lower end of the lock catch springboard is turned up and down around the upper end to be matched with or separated from the locking of the lower lock body, the lock catch springboard is provided with a lock push head, a lock rod and a sea lock, the lower lock body is provided with a lock groove, a lock top block, a coded lock and a button, one end of the lock push head is hinged on the lock catch springboard, the other end of the lock push head is matched with the lock top block, the lock catch springboard is turned down to lock the upper lock body and the lower lock body, the upper lock body and the lower lock body are pulled towards the locking direction until being locked, the lower end of the lock rod is provided with a lock head, the lock head is matched with the lock groove to lock the lock catch springboard on the lower lock body, the lock rod is provided with a lock hole and a lock protruding block, the customs lock comprises a customs lock cylinder and a customs lock block, the customs lock block is positioned at the lower end of the customs lock cylinder and rotates along with the customs lock cylinder, the customs lock block is inserted into the lock hole and drives the lock rod to move up and down along the matching direction of the lock head and the lock groove, the coded lock comprises a coded lock cylinder, a coded lock rod and a coded lock head, the coded lock cylinder is limited to move left and right by locking, the coded lock head is hinged on the lower lock body, one end of the coded lock head is matched with the coded lock rod, the coded lock head is driven to rotate around a hinging point when the coded lock rod moves left and right, the other end of the coded lock head is matched with a button, the button is limited to move inwards when the coded lock cylinder is locked, the button is provided with a button inclined block, two sides of the lock protruding block are inclined planes, the button inclined block is matched with the lock protruding block, and the button is pressed inwards, the lock rod is driven to move upwards through the cooperation of the button inclined block and the lock convex block to be separated from the cooperation with the lock groove.

The beneficial effects of the invention are as follows: through the downward turning of the lock catch gangway and the matching between the lock push head and the lock push block, the lock push head of the upper lock body and the lock push block of the lower lock body which are respectively fixed on the upper box body are realized, in the process of folding the lock catch gangway downwards, the lock push head applies upward pushing force to the lock push block, the pushing force is composed of the lock catch gangway hinged on the upper lock body and the lock push head hinged on the lock catch gangway, the connecting rod structure has a certain angle from the included angle of the lock catch gangway in the open state to the process of covering the lock catch gangway downwards to be at a zero angle of the lock state, in the process, the upper box body and the lower box body are drawn together, the pulling force can be released only by turning the lock catch gangway upwards again, and the pulling force and the lock catch gangway overturning are at a vertical angle, therefore, the lock rod and the locking groove which limit the upward turning of the lock catch springboard are matched, and the lock rod is pushed inwards at the moment, the lock head of the lock rod is separated from the matching with the locking groove, the upward turning limit of the lock catch springboard is released, the purpose of unlocking the lock catch is achieved, when the lock catch is needed, the lock catch springboard is only required to be turned downwards to be flat, the lock catch is locked, and the lock catch is driven to move transversely, the coded lock head is driven to rotate around the hinge point to a position for limiting inward movement of the button, at the moment, the lock head is matched with the locking groove again, and the button cannot move inwards to push the lock rod upwards; the other is to open the customs lock by the customs key, and the customs lock block is matched with the lock hole to drive the lock rod to move upwards when the customs lock core is rotated, so that the lock head is separated from the matching with the lock groove, the upward overturning limit of the lock catch springboard is released, the purpose of unlocking the lock catch is achieved, and when the lock catch is required to be locked, the lock catch springboard is only required to be overturned downwards to be covered flatly, and simultaneously, the customs lock core is rotated back to drive the lock rod to move downwards, so that the lock head is matched with the lock groove again.

Further, be equipped with the guide way on the lock body, be equipped with the direction projection on the lock body down, the direction projection inserts the cooperation with the guide way, sets up direction projection and guide way, can make lock body and lock body down more accurate in closure in-process location, it is more tight to fold, can not cause upper and lower box to fold the time to have left and right sides deviation.

The invention is described in further detail below with reference to the drawings and examples.
