Abstract

The invention provides an auxiliary lock. The auxiliary lock comprises an upper cover plate, a lower cover plate and a lock body. A ratchet shaft and a pawl shaft are arranged on the lock body. A ratchet is arranged on the ratchet shaft, and a ratchet return spring is arranged on the lock body and the ratchet. A pawl is arranged on the pawl shaft, and a pawl return spring is arranged on the lock body and the pawl. An inhaul cable supporting seat is arranged at the pawl end of the lock body, and an inhaul cable penetrates through the inhaul cable supporting seat to be fixedly connected with a zinc alloy casting head. The zinc alloy casting head is arranged on the pawl in a clamped manner. The upper cover plate is further arranged on the upper portion of the lock body, and the lower cover plate is further arranged on the lower portion of the lock body. A lock catch positioning block is arranged on the vertical surface of the lower cover plate, the lock catch positioning block is sleevedwith a lock catch positioning spring, the lock catch positioning block and the lock catch positioning spring are sleeved with a lock catch positioning shell, and the lock catch positioning shell is arranged on the vertical surface of the lower cover plate 7 in a clamped manner through four buckles and riveted with the vertical surface of the lower cover plate. The auxiliary lock is reasonable in structure, the auxiliary lock does not suffer from a main lock correlation relation, vibration and other environmental factors, the inhaul cable is prevented from disengaging, and the safety performance is improved.

Description

technical field [0001] The invention relates to the technical field of automobile door locks, in particular to an N526A auxiliary lock. Background technique [0002] At present, with the continuous enhancement of people's safety awareness, the safety requirements for locks are also getting higher and higher. The auxiliary lock is generally used as an auxiliary lock. It can be used to open and close the side door after matching with the main lock body of the rear double door or related actuators. in the non-door system. Existing door lock opening function: the matching main lock or actuator cable pulls the pawl and releases the ratchet to realize the door lock opening function; Influenced by environmental factors such as vibration, when the main lock or the actuator drives the cable linkage, sometimes the cable will fall off. Contents of the invention [0003] The purpose of the present invention is to solve the above technical problems and provide a secondary lock with ...
