Double-locking car emergency door lock capable of being opened from inside and outside

Abstract

The invention belongs to the technical field of cars, and particularly relates to a car emergency door lock. The double-locking car emergency door lock capable of being opened from inside and outsidecomprises an upper lock and a lower lock, wherein the upper lock and the lower lock are clamping plate type locks; the clamping plate type locks comprise fan-shaped swing arms; the swing arms of the upper lock and the lower lock are connected through a main lock rod; an inward opening lock rod of an inward opening handle is further connected onto the main lock rod; and an outward opening lock rodof an outward opening handle is connected onto the swing arm of the lower lock. By adopting the clamping plate type locks with two-gear locking functions, the door lock can be prevented from being accidently opened during the running process, so that the safety is high. Meanwhile, the inward opening handle and the outward opening handle are arranged, so that the door lock can be opened from insideand outside of the car so as to be convenient to use.
