Technical Field
[0001] The utility model relates to the technical field of door locks for maintenance of box-type power stations, in particular to a connecting rod lock used for a vehicle-mounted box-type power station. Background Art
[0002] The box-type power station is a device used for power generation and transmission. There are many electrical equipment integrated in the box. A maintenance door needs to be left on the outside of the box for inspection and maintenance. The maintenance door is usually closed and locked and can only be opened when the staff performs maintenance.
[0003] At present, the common box-type power station maintenance doors mainly adopt two forms:
[0004] (1) One side of the maintenance door is hinged and rotatably connected to the compartment body through the hinge. The other side uses two upper and lower door locks to lock the maintenance door. When performing maintenance or operation, the maintenance door can be opened by opening the upper and lower door locks. Figure 1 As shown in (a);
[0005] (2) Lock the maintenance door with door locks at the four corners and fix the maintenance door to the compartment. When performing maintenance or operation, open the door locks at the four corners and remove the maintenance door. Figure 1 As shown in (b) in .
[0006] Since most of the box-type power stations are installed on the vehicle-mounted platform of the supporting equipment, the height of the vehicle-mounted platform from the ground is generally about 1.3 meters.
