[0002] As the functional design of easy-to-use suitcases has become more and more important, there has been a demand for the function of quickly opening the suitcase without having to lay it down on the ground, especially for suitcases with zipper locks. Each time you open the suitcase, you need to lay it flat and pull the zipper completely into place before you can open it. Therefore, a design has emerged in which a cover that can be opened independently is provided on the front or back side of the suitcase and passes directly through the suitcase. However, this structure usually requires a lock body to lock each opening position, thereby increasing the number of lock bodies for the suitcase, making the structure of the lock body complicated, increasing production and installation costs, and also reducing reliability. Summary of the invention
[0003] The invention provides a suitcase with a dual-channel dual-control lock, which has the advantages of simple structure, low production cost and high reliability.
[0004] In order to solve the above technical problems, the present invention adopts the following technical scheme: a suitcase with a dual-channel dual-control lock, comprising an upper box body, a lower box body, a front cover plate and a lock body, the front cover plate is installed on the upper box body, the lock body is installed on the upper box body, the upper box body and the lower box body are closed by a zipper, the lock body comprises a lock group, a lock seat, a lock hook and an opening switch, the lock group comprises a lock core and a locking block, the lock core comprises a password lock core and a key lock core, the password lock core is provided with a password lock rod, the password lock rod is provided with a locking port, the locking port cooperates with the locking block to limit the locking block from moving along the opening direction of the opening switch, the lower end of the key lock core is provided with a long strip key opening dial block with arc-shaped ends, The locking block is provided with a "heart"-shaped pull groove, and the key-opening pull groove cooperates with the "heart"-shaped pull groove. When the key lock cylinder is turned to open, the lock block is driven to move along the opening direction of the vertical opening switch through the cooperation between the key-opening pull groove and the "heart"-shaped pull groove, so that the lock block is disengaged from the cooperation with the locking mouth. The lock seat comprises a front cover buckle lock seat and a zipper lock seat, and the front cover buckle lock seat is mounted on the front cover plate. The front cover buckle lock seat is provided with a front cover lock, and the zipper lock seat is mounted on the upper box body. The lock hook comprises a front cover lock hook and a zipper lock hook, and the front cover lock hook is locked and cooperated with the front cover lock buckle. The front cover lock hook is provided with a locking end, and the zipper lock hook is fixed on the zipper lock seat, and the zipper lock hook is locked and cooperated with the zipper head. The opening switch comprises an opening push block, a front cover opening swing rod and a zipper opening swing rod, the opening push block is provided with an opening protrusion, a locking block mounting groove and a key lock core mounting groove, the opening protrusion is respectively abutted and matched with the front ends of the front cover opening swing rod and the zipper opening swing rod on both sides along the opening direction of the opening switch, the locking block is installed in the locking block mounting groove and abutted and matched with the opening push block on both sides along the opening direction of the opening switch, and can move freely in the locking block mounting groove along the horizontal direction perpendicular to the opening of the opening switch, the key lock core is installed in the key lock core mounting groove, the front cover opening swing rod and the zipper opening swing rod are hinged on the zipper lock seat in the middle, and the front cover opening swing rod is provided with a locking boss and a front cover opening The locking boss and the locking end on the front cover lock hook are abutted and matched to limit the front cover lock hook from moving in the direction of disengaging from the locking cooperation with the front cover lock buckle, and the front cover opening boss and the opening protrusion are abutted and matched, and the front cover opening swing rod is driven by the opening protrusion to rotate in the direction of opening the front cover plate by the opening switch, so that the locking boss and the locking end are disengaged from the locking cooperation, and the front end of the zipper opening swing rod is provided with a zipper opening boss, and the rear end of the zipper opening swing rod is provided with a zipper opening end, the zipper opening boss and the opening protrusion are abutted and matched, and the zipper opening end cooperates with the zipper locking hook, and the zipper opening swing rod is driven by the opening protrusion to rotate in the direction of opening the zipper head by the opening switch, so that the zipper opening end opens the zipper locking hook.
[0005] The beneficial effect of the present invention is that locking or opening is achieved through the cooperation and disengagement of the locking block of the lock group and the lock core. When the password lock core is used to open, it is only necessary to adjust to the correct password. At this time, the password lock rod on the password lock core flips upward by a certain angle under the action of the spring, so that the locking mouth on the password lock rod that was originally in locking cooperation is dislocated up and down with the locking block to disengage the locking cooperation, thereby releasing the restriction on the locking block. At this time, it is only necessary to push the opening switch in the direction required to open, and push the front cover opening swing rod or the zipper opening swing rod through the opening push block of the opening switch, so as to drive the front cover opening swing rod or the zipper opening swing rod to rotate around the middle hinge hinged on the zipper lock seat, thereby releasing the restriction of the front cover opening swing rod on the front cover lock hook or opening the zipper lock hook through the zipper opening end provided at the rear end of the zipper opening swing rod, and finally achieving the opening. The purpose of opening the front cover or the upper box body by opening the zipper; when the customs key is used to open the key lock cylinder, the key lock cylinder is rotated, and the long strip key opening dial block with arc-shaped ends at the lower end of the key lock cylinder cooperates with the "heart"-shaped dial groove on the locking block, and the locking block is moved in the opening direction of the vertical opening switch, so that the locking block is withdrawn backward from the locking mouth on the password lock rod that was originally in the locking cooperation and disengaged from the locking cooperation. At this time, only the same operation as when the password lock cylinder is opened is needed to open the required front cover plate or upper box body. This structure is simple, very compact and reasonable, integrates two locking mechanisms together, and has the function of dual channels, has high reliability and low production cost, and at the same time, this simple structure of the front cover plate through a single front cover lock hook and the front cover lock buckle is more suitable for smaller travel cases.
[0006] Furthermore, the lock body is installed above the upper box body, near the edge of the front cover, and is in the middle position in the width direction of the upper box body. Setting the lock body in this position can make it easier to open the front cover when the box body is in a state where all four wheels are on the ground, and the items in the box body will not fall out, making it more convenient to use.
[0007] Furthermore, the zipper lock hook includes a zipper hook head, a locking spring, a zipper locking rod and a torsion spring. The zipper hook head cooperates with the locking spring to lock the zipper head. The lower end of the locking spring is fixed on the zipper locking rod. The zipper locking rod cooperates with the zipper opening end of the zipper opening swing rod. Driven by the zipper opening end, the zipper locking rod moves in the opening direction of the zipper head, so that the locking spring releases the cooperation with the zipper hook head and releases the locking restriction on the zipper head. The torsion spring provides an elastic force for the zipper hook head to flip upward and push the zipper head away from the locked state. This structure can be more convenient to operate when the zipper head is locked in the zipper hook head, and it is also more convenient for the zipper head to pop out automatically when the zipper lock hook is opened.
