Abstract

The invention discloses a cabin door locking device of a special vehicle. The cabin door locking device comprises a cabin door and a deck; a cabin door through hole is formed in the cabin door, and alock sleeve is arranged in the cabin door through hole; a rotatable lock shaft is arranged in the lock sleeve, and one end of the lock sleeve is in transmission connection with a lock tongue arrangedon the inner side of the cabin door; the lock tongue can move in the axis direction of the lock shaft, and is provided with a lock tongue threaded hole, and a first outer thread matched with the locktongue threaded hole is arranged on the lock shaft; and a sealing part is arranged on the inner side of the deck and internally provided with a flexible sealing piece, and when the cabin door is closed, a flange on the inner side of the cabin door compresses the flexible sealing piece. According to the cabin door locking device of the special vehicle, the pressure of the locking device on the cabin door locking position is adjustable, and the cabin door locking device is small in occupied space, good in airtightness, high in reliability, simple in structure and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of special vehicle equipment, in particular to a special vehicle cabin door locking device. Background technique [0002] At present, domestic special vehicle cabin door lock devices have different locking structures according to different usage requirements. There are mainly two types: the first type of cabin door locking device usually adopts a bolt locking mechanism, and the locking action design is divided into closing first and then locking. Lock in two steps. Its advantage is that the locking adjustment stroke is large and the sealing is reliable. The disadvantage is that the device requires a large space for installation and operation, and it can only be used in specific parts. Most of them are used in environments with high sealing requirements and no running, leaking, dripping, and leaking are allowed; the second type of cabin door lock device mostly adopts a wedge surface compression structure, w...
