Problems solved by technology
[0003] The doors of engineering vehicles are generally open and close, but the working environment of engineering vehicles is relatively harsh. Taking excavators as an example, excavators vibrate violently under working conditions, and the door locks are fixed on the cab by bolts. The accident rate of the problem is relatively high, resulting in inflexible opening of the door lock

The invention discloses a locking device for the side door of an engineering vehicle operating room, which includes a lock and a locking block. The lock includes two panels arranged symmetrically. The two panels are matched with door handles respectively. connected, the mandrel is connected to the clamping plate, and the locking clamping block includes two symmetrically arranged fixed plates, a vertical arc-shaped plate is arranged on one of the fixed plates, and a baffle plate is arranged under the arc-shaped plate. The upper 2 / 3 of the arc-shaped plate is a gentle slope, and the lower 1 / 3 of the arc-shaped plate is a steep slope. , the bottom of the spring is connected to the lower end of the arc plate, and the clamping plate is stuck between the steep slope and the baffle plate. The revolving door handle of the present invention can be locked by the spring plate and will not rebound upwards under the action of gravity. , simple structure, convenient and safe opening and closing, low production cost, and good application and promotion value.
Description
technical field [0001] The technical field of engineering vehicles of the present invention particularly relates to a locking device for a side door of an operating room of an engineering vehicle. Background technique [0002] At present, in various engineering constructions, engineering vehicles are more and more widely used. Engineering vehicles are the backbone of construction projects, including large cranes, excavators, bulldozers, road rollers, loaders, electric emergency repair vehicles, engineering emergency vehicles, electric welding Engineering vehicles, etc. Because of their appearance, the progress of construction projects has been doubled, manpower has been greatly reduced, and construction efficiency and quality have been improved. [0003] The doors of engineering vehicles are generally open and close, but the working environment of engineering vehicles is relatively harsh. Taking excavators as an example, excavators vibrate violently under working conditions...
