Detailed Description
When the rear lower door 1 is to be opened, the cylinder rod of the oil cylinder 3 begins to contract, the rear lower door 1 is pulled, the guide rod 10 moves upwards in the guide sleeve 12, the spring rebounds, the rear lower door 1 begins to be vertically lifted under the combined action of the spring and the oil cylinder, when the turnover sleeve 8 is abutted to the lower end of the rear upper door, the door handle 7 is separated from the door handle seat 6, the lock pin 14 is separated from the groove of the upper opening of the locking seat 13, the rear lower door 1 begins to rotate upwards around the turnover sleeve, and the rear lower door is gradually opened, as shown in fig. 4-5.
When the rear lower door 1 needs to be closed, the cylinder rod of the oil cylinder 3 begins to extend to push the rear lower door 1 to start to rotate downwards around the turnover sleeve, in the process of the downward rotation, the turnover sleeve 8 is driven to be always abutted against the lower end of the rear upper door under the action of the elastic force of the spring 9, when the rear lower door is finally in a vertical state, the door handle 7 is positioned above the door handle seat 6, the lock pin 14 is positioned above the groove of the upper opening of the locking seat 13, the rear lower door 1 closes the rear end of the carriage but is not locked, at the moment, the cylinder rod of the oil cylinder 3 extends for the last time to push the whole rear lower door 1 to vertically descend, at the moment, the guide rod 10 moves downwards in the guide sleeve 12, the spring is compressed, as shown in figures 1-3, the rear lower door 1 is in a closed state, the cylinder rod of the oil cylinder 3 is in a completely extended state, the door handle 7 is clamped on the door handle seat 6, and the lock pin 14 enters the groove of the upper opening of the locking seat 13 to be completely locked, the rear lower door 1 is locked up and down under the action of the gravity of the rear lower door.
