The working principle of the invention is as follows: as shown in fig. 1, when the door is opened, if the speed is too high, the door rotates around the shaft, and the piston rod 3 is pushed by the connecting rod 2 to move rapidly to the left inside the hydraulic cylinder 4 under the guiding action of the guide sleeve one 13, and the piston plate one 12 is pushed to push the liquid inside the hydraulic cylinder 4 rapidly, the liquid inside the hydraulic cylinder 4 compresses rapidly, the pressure inside the high-pressure chamber between the piston plate one 12 and the piston plate two 11 increases rapidly, the liquid overflows from the overflow pipe 5 to the inside of the limit cylinder 6, so that the pressure inside the limit cylinder 6 increases, as shown in fig. 2, after the pressure inside the limit cylinder 6 increases, the liquid pushes the piston plate three 14 to drive the limit rod 16 to move synchronously, so that the limit rod 16 moves downwards along the guide sleeve four 17 to be inserted into the space on the piston rod two 8, so as to limit the left movement of the piston rod two 8, and if the door is opened continuously, the pressure inside the hydraulic cylinder 4 exerts, the resistance of the piston plate I12 moving leftwards is increased, and the door is limited and stopped through the piston rod I3 and the connecting rod 2, so that the safety of the door when the door is opened is ensured;

after the box door rotates reversely for a certain angle, the first piston rod 3 is pulled to move right through the connecting rod 2, the first piston plate 12 is synchronously driven to move right to reduce the pressure in the hydraulic cylinder 4 and the limiting cylinder 6, the third piston plate 14 is pushed to move upwards under the action of the spring 15, the limiting rod 16 is driven to move upwards synchronously, the lower end of the limiting rod 16 is separated from the second piston rod 8, and the limitation on the second piston rod 8 is released;

if the opening of the box door is slow at a constant speed, the box door pushes the piston plate I12 to extrude liquid in the hydraulic cylinder 4 at a constant speed through the connecting rod 2 and the piston rod I3, the increase amplitude of the pressure in the hydraulic cylinder 4 is small, the pressure difference value in the limiting cylinder 6 is small, the spring 15 has reverse acting force which is enough to overcome the increase amplitude of the pressure in the limiting cylinder 6, along with the slow increase of the pressure in the hydraulic cylinder 4, the piston plate II 11 is forced to move to the left, and the piston rod II 8 is pushed to move to the left at a constant speed, so that the uniform-speed safe opening of the box door;

after the door is opened for a certain angle, the piston rod II 8 correspondingly moves leftwards along the guide sleeve II 10 and the guide sleeve III 7 for a certain distance, the process of moving leftwards of the piston rod II 8 enables the lock rod 92 to be inserted and buckled in the space formed by the partition boards 81 on the piston rod II 8 one by one, under the action of the limiting block 94, the second piston rod 8 can not move rightwards, so that the door is prevented from being closed under the action of external force after being opened, therefore, the loading and unloading of goods are convenient, when the box door needs to be closed, the poking rod 93 is poked to overcome the resistance of the coil spring so that the lock rod 92 is not contacted with the second piston rod 8, the one-way locking state of the second piston rod 8 is released, the box door is closed, and when the box door is closed, the first piston rod 3 is pulled to move rightwards through the connecting rod 2, and the second piston rod 8 is driven to move rightwards to reset through the pressure difference between the inside and the outside of the hydraulic cylinder 4, so that the box door is limited again when the box door is started next time, and the whole process is simple in operation, safe and reliable.
