Description

Double-channel buckle lock for suitcase

Technical Field

The invention relates to a double-channel buckle lock of a travel suitcase.

Background

Along with the appearance design of the suitcase is more and more emphasized, more and more short and wide vertical buckling lock designs are generated to replace the traditional long and narrow transverse side buckling lock design, but new defects also occur, the traditional iron hook structure is cancelled for the sake of attractiveness, the strength of the buckling lock is insufficient, the vertical folding force of the suitcase body is insufficient, gaps are left between the upper suitcase body and the lower suitcase body, the folding of the suitcase body is not tight, even the suitcase body is easy to cause that the suitcase body is not locked and opened, particularly in the buckling lock with a double-channel function, the traditional structure is more complex, and the defects of easy failure exist.

Disclosure of Invention

The invention provides a dual-channel buckle lock 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: a double-channel buckle lock for a suitcase comprises an upper lock body, a lower lock body and a buckle springboard, wherein the upper lock body is fixed on an upper box body, the lower lock body is fixed on a lower box body, the upper end of the buckle springboard is hinged on the upper lock body, the lower end of the buckle springboard is overturned up and down around the upper end to be matched with or separated from the locking of the lower lock body, a lock pusher, a lock rod and a customs lock are arranged on the buckle springboard, a lock groove, a lock top block, a coded lock and a button are arranged on the lower lock body, one end of the lock pusher is hinged on the buckle springboard, the other end of the lock pusher is matched with the lock top block, the buckle springboard is overturned downwards to lock the upper lock body and the lower lock body, the upper lock body and the lower lock body are straightened to be locked towards a locking direction through the abutting fit of the lock pusher and the lock top block, a lock head is arranged at the lower end of the lock rod, and the lock groove is matched with the buckle springboard to lock the lower lock body, the lock rod is provided with a lock hole and a lock convex 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 and a coded lock rod, one end of the coded lock rod is connected with the lower lock body, the other end of the coded lock rod is a free end, the coded lock rod is provided with a coded lock head at the free end, the coded lock rod is limited to turn up and down around a connecting point on the lower lock body when the coded lock cylinder is locked, the coded lock head moves up and down along with the coded lock rod, the coded lock head is matched with a button, the button moves inwards when the coded lock cylinder is locked, the button is provided with a button inclined block, two sides of the lock convex block are inclined planes, the button inclined block is matched with the lock convex block, and the button is pressed inwards, the locking rod is driven to move upwards to be separated from the matching with the locking groove through the matching of the button inclined block and the locking convex block.

The invention has the beneficial effects that: the lock push head of the upper lock body fixed on the upper box body and the lock push block of the lower lock body fixed on the lower box body are respectively fixed through the downward overturning of the lock catch springboard and the matching between the lock push head and the lock push block, in the process of downwards folding the lock catch springboard, the upward pushing force is exerted on the lock push block by the lock push head, the pushing force is a connecting rod structure consisting of the lock catch springboard hinged on the upper lock body and the lock push head hinged on the lock catch springboard, the connecting rod structure has a process from a certain angle when the lock catch springboard is in an opening state to a zero angle when the lock catch springboard is in a locking state, in the process, the upper box body and the lower box body are drawn together, the pulling force can be relieved only when the lock catch springboard is overturned upwards again, and the pulling force and the lock catch springboard are overturned to form a vertical angle, so that the matching of a lock rod and a lock groove of the upwards overturning of the lock catch springboard is limited, when the suitcase needs to be unlocked, the password lock can be unlocked by the password lock, only the password lock cylinder needs to be accurately unlocked by the password, the limitation on the password lock rod is removed, the password lock rod drives the password lock head to upwards turn around the connecting point of the password lock rod under the action of the return spring, the password lock head at the suspended end of the password lock rod upwards moves to the position where the limiting button is removed from inwards moving, the button is pushed inwards at the moment, the button inclined block on the button is matched with the inclined planes at the two sides of the lock convex block on the lock rod to upwards push the lock rod, the lock head of the lock rod is separated from being matched with the lock groove, the limitation on the upwards turning of the lock springboard is removed, the purpose of unlocking the buckle is achieved, and when the buckle is required to be locked, the buckle board only needs to downwards turn over the cover to be flat, and the password lock cylinder is locked to drive the password lock rod to downwards turn over, the coded lock head is driven to move downwards to return to the position where the limiting button moves inwards, at the moment, the lock head is matched with the lock groove again, and the button cannot move inwards to push the lock rod upwards; the other type is that the customs lock is opened through a customs key, the customs lock block is matched with the lock hole while the customs lock cylinder is rotated to drive the lock rod to move upwards, so that the lock head is separated from being matched with the lock groove, the limitation of upwards overturning of the lock catch springboard is removed, and the aim of unlocking the lock catch is achieved.

Furthermore, the upper lock body is provided with a guide groove, the lower lock body is provided with a guide convex column, the guide convex column is inserted and matched with the guide groove, and the guide convex column and the guide groove are arranged, so that the upper lock body and the lower lock body can be positioned more accurately in the folding process and can be folded more tightly, and left and right deviation can not be caused when the upper box body and the lower box body are folded.

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