Problems solved by technology

High machining accuracy. For the thin-shell welded car body and shell-type door, it is difficult to meet the flatness requirements due to the relatively large size. Even if special tooling is used, it is not easy to ensure
In addition, because the bulletproof plate used for the car body and the door cover is relatively thin, generally 3-6mm, the welding deformation is large, and the gap between the door cover and the door frame after welding is large and uneven, and the gap can reach up to 6-8mm
It is locked by the hasp. Due to the small pressing force, the pressing amount is less than 4mm, and it is not adjustable. In addition, there are few locking points (generally two places). Therefore, in all cases of locking the hasp, the sealing strip and The door frame cannot be fully fitted and pressed, and there are still gaps in some parts, resulting in water leakage and failing to meet the waterproof performance requirements

Abstract

The invention relates to a vehicle door, especially providing a bulletproof waterproof door, which is formed by a frame, a door cover, a sealing bar, hinge, inner door plate, thermal-insulated plate, locking device, bolt, incline block and door lock. With said invention, the defects of wheel or track armored car can be solved, to confirm non-water leakage when on water.

Description

Technical field: [0001] The invention belongs to the field of vehicle doors, in particular to a bulletproof watertight door. Background technique: [0002] The car door of the wheeled (or tracked) armored vehicles produced in China and equipped by the army now has bulletproof or non-bulletproof according to its use protection requirements. Bulletproof mainly refers to anti-7.62mm piercing incendiary bombs. According to its sealing requirements, some are weatherproof and some are waterproof and airtight. However, the door structure adopts a split structure, that is, the door frame (usually cylindrical steel bar welded or machined) is welded on the car body, and the door cover (Stamping forming) It is welded on the car body through the hinge and then forms the whole door with the door frame. The locking and sealing of the door is realized by two hasps in the car. This kind of door requires the flatness of the car body and the door cover to be very high, generally not greater...
