When the buffer plate rotates downward, the connecting rope will be pulled, and the connecting rope will be pulled to rotate the card block in the direction of the connecting rope. The rotation of the card block in the direction of the connecting rope will release the limit of the card slot, thereby preventing the goods from falling off the shelf after collision, causing damage to the goods and affecting the transportation of the goods.

[0007] According to the above technical solution, a No. 1 torsion spring is provided between the connecting block and the short rod, and a No. 2 torsion spring is provided between the clamping block and the round rod. The clamping block is in contact with the surface of the clamping slot, and the connecting block is reset by the No. 1 torsion spring, and the clamping block is reset by the No. 2 torsion spring.

[0008] The lifting device comprises a base, a hinged block, a rotating shaft, a support rod, a fixed block, a pulley and a driving device. When the driving device is started, the support rods are driven by the driving device to move toward each other. The toward-direction movement of the support rods drives the fixed blocks to move toward each other. The toward-direction movement of the fixed blocks drives the pulleys to move toward each other. The base is arranged at the bottom of the shelf, the hinged block is fixedly mounted on the top of the base, the rotating shaft is rotatably mounted on the surface of the hinged block, the support rod is fixedly mounted on the rotating shaft surface, the fixed block is fixedly mounted on the surface of the support rod, the pulley is rotatably mounted on the inner wall of the fixed block, and the pulley is slidably mounted on the bottom of the shelf.

The L-shaped rods are driven to move toward each other by the support rods, and the L-shaped rods are driven to move toward each other by the arc blocks, and the arc blocks are pushed to move toward each other. The L-shaped rod is fixedly mounted on the surface of the fixed block, and the arc block is fixedly mounted on the top of the L-shaped rod. A connecting rod is slidably mounted on the inner wall of the slide groove, and the push plate is fixedly mounted on the surface of the connecting rod.

[0012] According to the above technical solution, an elastic telescopic rod is fixedly installed at the bottom of the push plate, a brush plate is fixedly installed at the free end of the elastic telescopic rod, a protrusion is fixedly installed on the top of the brush plate, a square block is fixedly installed on the inner wall of the shelf, and an arc plate is fixedly installed on the bottom of the square block. The push plates move toward each other, which drives the elastic telescopic rod to move toward each other, and the elastic telescopic rod moves toward each other, which drives the brush plate to move toward each other. The brush plate cleans up impurities inside the shelf to prevent impurities from sticking to the goods and affecting the delivery of the goods. It can also prevent impurities from sticking to the brush for a long time, resulting in a decrease in the cleaning effect of the brush.

[0013] According to the above technical solution, the brush plate contacts the bottom of the inner wall of the shelf, and a groove is provided at the bottom of the shelf.

[0014] The present invention provides a cargo protection bracket having the following beneficial effects:

[0015] (1) This invention can cushion the impact of a collision through a buffer plate, preventing the goods inside the shelf from falling over and causing damage to the goods. At the same time, the collision will pull the connecting rope, which will release the limit on the elastic telescopic plate. The free end of the elastic telescopic plate will pop out to seal the shelf, preventing the goods from falling off the shelf after a collision, causing damage to the goods and affecting the transportation of the goods.

[0016] (2) This invention controls the height of the shelf through a driving device, and can load and unload goods of different heights. It is convenient and flexible, and prevents the goods from being too high, which affects the loading and unloading efficiency. At the same time, when the shaft rotates, it will contact the triangular block. By pushing the triangular block toward the inside of the lubrication box, the oil inlet opened on the surface of the sliding rod enters the oil tank, allowing a small amount of lubricating oil to enter and then be applied to the surface of the shaft through the triangular block, thereby preventing the shaft from being worn for a long time. Failure to apply lubricating oil in time will result in a reduction in the service life of the equipment.

[0017] (3) This invention, when the shelf is raised by the driving device, uses the support rods to move in opposite directions to drive the L-shaped rods to move in opposite directions, so that the push plates limit the goods to prevent the goods from sliding inside the shelf and causing damage to the goods. At the same time, when the push plates move in opposite directions, they will drive the brush plates to clean the impurities inside the shelf and remove the impurities from the shelf to prevent the impurities from adhering to the goods and affecting the delivery of the goods. At the same time, the contact between the protrusions and the curved plate will generate vibration, which will shake off the impurities adhering to the brush and prevent them from adhering to the brush for a long time, resulting in a decrease in the cleaning effect of the brush.
