Abstract

The invention belongs to the technical field of armored vehicles and particularly relates to a stepless adjustable opening angle type top hold door. The stepless adjustable opening angle type top hold door is suitable for all top hold doors with the upturning opening mode. A ratchet and pawl structure and a guide groove assembly are additionally arranged in the position of a hinge of the top hold door, the structure is simple, movement is reliable, the stepless adjustable property of the opening / closing angle is achieved in the opening and closing processes of the top hold door, the top hold door can be fixed to any position in the stroke range, a limiting block and a lock hook in the existing design are omitted, and accordingly, the number of welding parts of a top deck is decreased. According to the top hold door provided by the invention, the problems that the parking position of an existing top hold door is simplex, the man-equipment-environment condition is poor, and a locking device is heavy are solved. Meanwhile, the protecting area of personnel can be increased by decreasing the opening angle of the top hold door, and the safety in the process that the personnel enter or exit from a vehicle and the shooting safety can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of armored vehicles, and in particular relates to a roof hatch door with a steplessly adjustable opening angle of an armored vehicle, which is applicable to all roof hatch doors whose opening mode is an upturning type. Background technique [0002] The existing roof hatch structure of armored vehicles, such as figure 1 shown. When the top cabin door is opened, only one position can be fixed by the locking mechanism including the locking device and the buffer rubber block, such as figure 2 As shown, that is, the member opens the lock hook from the inside of the vehicle, pushes the top cabin door outward to the limit position, and fixes it with the locking device and the buffer rubber block. At this time, the opening angle of the cabin door is about 120-150 degrees. Crew in and out. When closing the doors and windows, the member releases the locking device of the top cabin door and pulls the door handle to...
