Armored vehicle door lock structure

Abstract

The invention provides an armored vehicle door lock structure. The structure comprises a lock plate, one side of the lock plate is provided with an outward opening linkage arm rotary shaft, an openingrocker arm is fixed to the outward opening linkage arm rotary shaft, and a locking linkage shaft is fixed to the tail end of the opening rocker arm. The other side on the lock plate is provided withan outward opening switching arm rotary shaft, an outward opening switching arm is fixed to the outward opening switching arm rotary shaft, and a rectangular sliding groove sleeving the locking linkage shaft is formed in the tail end of the outward opening switching arm. The structure also comprises an inner locking rotary shaft arranged on the upper portion of the outward opening switching arm rotary shaft, an inner locking rocker arm is fixed to the inner locking rotary shaft, an arc-shaped limiting groove is formed in the lower end of the inner locking rocker arm, the locking linkage shaftis disposed in the limiting groove, and the upper portion of the inner locking rocker arm is connected with an inner locking torsion spring. The structure also comprises an inner locking lifting button which is fixed to the upper end of the inner locking rocker am and extends out of the lock plate. A locking point between a vehicle door and a door frame is increased through cooperation of a push type panic bar and a lock catch in the middle, and the impact wave resistance of the vehicle door is improved.

Description

technical field [0001] The invention relates to a lockset, in particular to a door lock structure of an armored vehicle door. Background technique [0002] Public security vehicles, armed police vehicles and escort vehicles are all special vehicles. Due to safety requirements, the safety performance of special vehicles is particularly important. As the main shielding object inside and outside the vehicle, the quality of the door directly affects the safety performance of the vehicle. For general-purpose vehicles, a door locking mechanism can meet the door locking requirements, but for special vehicles carrying artillery, the conventional door locks will be deformed or deformed due to the impact of the shock wave when the artillery is fired. If it is washed open, then, how to improve the performance of the car door from the door lock has become a problem to be solved. Contents of the invention [0003] In view of the above problems, the present invention makes research an...
