[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: when the air compressor is in use, the air compressor is stored in a container in order to protect the air compressor, and the container is locked in order to ensure the safety of the air compressor. The existing container locks are relatively complicated. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a simple lock buckle for an air compressor.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a simple lock for an air compressor, comprising a storage box with a hollow interior, a mounting opening penetrating through the side wall of the storage box, a mounting door rotatably arranged in the mounting opening, a fixing plate fixedly arranged on the inner wall of the mounting opening, a U-shaped frame with a U-shaped cross section fixedly arranged on the side wall of the fixing plate, a mounting groove arranged on the side wall of the mounting door, a through groove penetrating through the inner wall of the mounting groove, a rotating plate rotatably arranged in the mounting groove, a mounting plate with an L-shaped cross section arranged on the side wall of the U-shaped frame close to the fixed plate, and the other end of the mounting plate is fixed to the rotating plate.

[0006] By adopting the above technical solution, when the staff needs to open the storage box to repair and maintain the air compressor in the storage box, the staff needs to rotate the rotating plate, and then the mounting plate rotates with the rotating plate under the action of the rotating plate, so that the mounting plate and the U-shaped frame are separated from each other. At this time, the staff pulls the rotating plate, and then the mounting door rotates under the action of the rotating plate, so as to open the storage box to repair and maintain the air compressor in the storage box. In this process, the mounting door is opened or closed only by the U-shaped frame and the mounting plate, thereby reducing the complexity of the device.

[0007] Furthermore, a rotation groove is provided on two opposite inner walls of the installation groove, a reset groove is provided on the inner walls of the two rotation grooves that are away from each other, a rotation rod is arranged in the two rotation grooves for common rotation, a torsion spring is fixedly arranged on the inner walls of the two reset grooves that are away from each other, the other ends of the two torsion springs are fixedly arranged on the side walls of the rotation rod, and the rotation rod passes through the rotation plate and is fixed to the rotation plate.

[0008] By adopting the above technical solution, when the staff rotates the rotating plate, the rotating rod rotates under the action of the rotating plate. Then, when the staff closes the installation door, the staff loosens the rotating plate, and the rotating rod rotates in the opposite direction under the action of the torsion spring, so that the rotating plate rotates in the opposite direction under the action of the rotating rod, and the rotating plate is reset, thereby reducing the difficulty of resetting the rotating plate for the staff.

[0010] By adopting the above technical solution, when the staff needs to rotate the fixed rotating plate, the staff needs to rotate the rotating rod, and then the blocking rod rotates synchronously with the rotating rod under the action of the rotating rod, so that the blocking rod rotates away from the end of the rotating rod to the blocking groove, and then the blocking rod limits the rotating plate, thereby reducing the probability of the rotating plate rotating when subjected to external force.

[0011] Furthermore, a keyhole is provided on the side wall of the rotating rod, a plurality of slide grooves are penetrated on the inner wall of the keyhole, a plurality of driving grooves opposite to the plurality of slide grooves are provided on the inner wall of the rotating groove, a first spring is fixedly provided on the inner top wall of the plurality of driving grooves, a driving rod is fixedly provided on the other end of the plurality of first springs, a sliding rod is slidably provided in the plurality of slide grooves, the driving rod is slidably connected to the slide groove, the sliding rod is slidably connected to the driving groove, and the driving rod is slidably connected to the driving groove.

[0012] By adopting the above technical solution, when the staff needs to rotate the rotating rod, the staff needs to insert the key into the keyhole, so that the slide bar slides upward under the action of the key, so that the driving rod slides upward under the action of the slide bar, and then the end of the driving rod close to the slide bar is separated from the slide groove under the action of the slide bar and all slides into the driving groove. At this time, the staff can rotate the rotating rod by turning it, thereby reducing the probability of the rotating rod rotating when it is subjected to external force, thereby improving the stability of the device. In addition, the first spring reduces the difficulty of resetting the slide bar and the driving rod, thereby reducing the difficulty of the staff's work.

[0013] Furthermore, the lengths of the plurality of sliding bars are different.

[0014] By adopting the above technical solution, the different lengths of the plurality of sliding rods improve the safety of the device, thereby reducing the probability of keys with different patterns turning the rotating rod.

[0015] Furthermore, the side wall of the rotating plate is provided with rounded corners.

[0016] By adopting the above technical solution, the rounded corners reduce the probability of collision during the rotation of the rotating plate, thereby improving the stability of the device.

[0017] Furthermore, the upper surface of the storage box is sealed with a cover.

[0018] By adopting the above technical solution, when the staff needs to refuel the air compressor in the storage box, the staff can refuel the air compressor by opening the sealing cover, thereby reducing the difficulty of the staff's work.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. In this application, when the staff needs to open the storage box to repair and maintain the air compressor in the storage box, the staff needs to rotate the rotating plate, so that the installation plate rotates with the rotating plate under the action of the rotating plate, so that the installation plate and the U-shaped frame are separated from each other. At this time, the staff pulls the rotating plate, so that the installation door rotates under the action of the rotating plate, so as to open the storage box to repair and maintain the air compressor in the storage box.
