Locking mechanism of rear door of compressed garbage truck

Abstract

The invention relates to the field of door structures of garbage trucks, in particular to a locking mechanism of a rear door of a compressed garbage truck. One end of a telescopic drive device is rotationally connected to a door body, and the other end of the telescopic drive device is arranged adjacent to a limiting part on a box body; when the telescopic drive device stretches, the telescopic drive device pushes against the limiting part to push the door open; one end of a transmission rod is rotationally connected to the telescopic drive device, and the other end of the transmission rod isprovided with a locking block matched with a locking hook on the door body; and the transmission rod enables the locking block to be inserted into the locking hook when the telescopic drive device isin a retracting state, so as to prevent the door body from being opened accidentally. Moreover, when the telescopic drive device retracts, a guide device can guide the tail end (the locking block) ofthe transmission rod to swing away from the door body; the locking block drives the locking hook and the door body to continue to move towards the box body; and therefore, when the door body is beingclosed, the locking mechanism can continue to actively pull the door body to move towards the box body to ensure that the door body can press the box body tightly, so as to ensure the sealing betweenthe door body and the box body to prevent the leakage of wastewater.

Description

technical field [0001] The invention relates to the field of garbage truck door structures, in particular to a locking mechanism for compressing the rear door of a garbage truck. Background technique [0002] The compressed garbage truck is equipped with a box for containing garbage. There is a hatch at the rear of the box, which can be opened or closed. At the same time, a sealing strip is set between the hatch and the box to improve of tightness. In order to lock the door and the box and prevent the door from being opened accidentally, the compressed garbage truck is also equipped with a door locking mechanism. The existing door locking mechanism is generally provided with a lock pin on the door and a movable lock hook on the box. When the door is closed, the lock hook engages with the lock pin, and the inner wall of the lock hook is round. When the lock pin is inserted into the lock hook, the lock pin slides along the inner wall of the lock hook, so that the lock pin dr...
