Technical Field
[0001] The invention 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 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

The opening switch includes an opening push block 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 moves along the opening switch opening. The two sides of the opening direction are respectively abutted and matched with the locking ends on the front cover locking rod and the front end of the zipper opening swing rod; 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 switch; the key lock cylinder is installed in the key lock cylinder mounting groove; the middle part of the zipper opening swing rod is hinged on the zipper lock seat; 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 abuts and matches with the opening boss, and the zipper opening end cooperates with the zipper lock hook, and the zipper opening swing rod is rotated along the direction of opening the zipper head by the opening switch under the drive of the opening boss, so that the zipper opening end opens the zipper lock 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 is flipped 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 to be opened, and the opening push block of the opening switch can push the front cover locking rod or the zipper opening swing rod, thereby driving the front cover locking rod to move in the opening direction or driving the zipper to open. The swing lever rotates around the middle hinge hinged on the zipper lock seat, and then moves in the opening direction through the two push-pull ends on the front cover lock rod at the same time, and drives the front cover lock head to rotate around the fixed axis through the cooperation with the push-pull protrusion until the lock head locking end is disengaged from the locking cooperation with the hook head locking end, and then provides a force through conventional methods such as torsion springs or spring leaves to make the front cover hook head flip around the rotating axis, and through the cooperation of the flipping end and the guide push end, the front cover is pushed outward, and the locking head of the front cover hook head is disengaged from the cooperation with the front cover lock hole (when closing the front cover, the guide push end pushes the flipping end and overcomes the spring elastic force to make the front cover hook head rotate around the rotating axis The zipper lock hook is opened by the zipper opening end provided at the rear end of the zipper opening swing rod, and the front cover is finally opened or the upper box body is opened 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 block with arc-shaped ends at the lower end of the key lock cylinder and the "heart" shaped key opening groove on the locking block are opened. The lock block is moved in the direction of opening the vertical opening switch, so that the lock block is withdrawn backward from the lock mouth on the password lock rod that was originally in the lock cooperation and disengaged from the lock cooperation. At this time, only the same operation as when the password lock cylinder is opened is needed to open the required front cover or upper box. This structure is simple, very compact and reasonable. It integrates the two locking mechanisms together and has the function of dual channels. It has high reliability, good firmness and low production cost. At the same time, this structure of the front cover plate locking with the front cover lock hole through two front cover hooks is more suitable for larger travel cases and can provide greater firmness.
[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.
