Description

Technical Field

[0001] The utility model relates to a suitcase with a double-channel double-control lock. Background Art

[0002] As the functional design of easy-to-use suitcases has become increasingly important, there has been a demand for the function of quickly opening the suitcase without having to lay it down on the ground. This is especially true for suitcases with zipper locks, which require the suitcase to be laid flat and the zipper to be fully pulled into place each time before they can be opened. Therefore, a design has emerged in which a cover that can be opened independently and passes directly into the suitcase is provided on the front or back side of the suitcase. However, this structure usually requires a lock body to lock each opening position, thereby increasing the number of lock bodies in the suitcase, making the lock body structure more complicated, increasing production and installation costs, and also reducing reliability. Summary of the Invention

[0003] The utility model 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 solutions: a suitcase with a dual-channel dual-control lock, comprising an upper box body, a lower box body, a front cover and a lock body, the front cover plate being mounted on the upper box body, the lock body being mounted on the upper box body, the upper box body and the lower box body being closed by a zipper, the lock body comprising a lock group, a lock seat, a lock hook and an opening switch, the lock group comprising a lock cylinder and a locking block, the lock cylinder comprising a password lock cylinder and a key lock cylinder, the password lock cylinder being provided with a password lock rod, the password lock rod being provided with a locking port, the locking port cooperating with the locking block to restrict the locking block from moving in the opening direction of the opening switch, the lower end of the key lock cylinder being provided with a long strip key opening dial block with arc-shaped ends The lock 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 lock mouth. The lock seat includes 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 includes a front cover lock hook and a zipper lock hook, and the front cover lock hook is locked with the front cover lock buckle. A locking end is provided on the front cover lock hook, and the zipper lock hook is fixed on the zipper lock seat, and the zipper lock hook is locked with the zipper head. The opening switch includes an opening push block, a front cover opening swing rod and a zipper opening swing rod, and the opening push block is provided with an opening protrusion, a locking block mounting groove and a key lock cylinder 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, and 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, and the key lock cylinder is installed in the key lock cylinder mounting groove, the middle parts of the front cover opening swing rod and the zipper opening swing rod are hinged on the zipper lock seat, and the front end of the front cover opening swing rod is provided with a locking protrusion and a front cover opening The zipper opening end cooperates with the zipper lock hook, and the zipper opening swing rod is driven by the opening protrusion to rotate along the direction of opening the zipper head by the opening switch, so that the zipper opening end opens the zipper lock hook.

[0005] The beneficial effect of the utility model is that locking or unlocking is achieved by the cooperation and disengagement of the locking block of the lock group and the lock cylinder. When the password lock cylinder is opened, it is only necessary to adjust the correct password. At this time, the password lock rod on the password lock cylinder is tilted 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 the locking cooperation is dislocated up and down and disengaged from the locking cooperation, thereby releasing the restriction of the locking block. At this time, it is only necessary to push the opening switch in the direction required to open, and the opening push block of the opening switch pushes the front cover opening pendulum rod or the zipper opening pendulum rod, which can drive the front cover opening pendulum rod or the zipper opening pendulum rod to rotate around the middle hinge connected to the zipper lock seat, thereby releasing the restriction of the front cover opening pendulum 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 pendulum rod, and finally achieving the opening. The purpose of opening the front cover or opening the upper box 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 to move the locking block in the opening direction perpendicular to the 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 opening the password lock cylinder is needed to open the required front cover or upper box. This structure is simple, very compact and reasonable, integrates the two locking mechanisms together, and has a dual-channel function, has high reliability and low production cost. At the same time, this simple structure of the front cover being locked with the front cover lock hook by a single 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 located 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 four-wheeled state, and will not cause the items in the box to scatter 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 make the zipper head more convenient to operate when it 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.
