Machinery compartment door lock

Abstract

The invention belongs to vehicle door locks, particularly relates to a door lock between machines and solves the problems that the existing vehicle door lock has complicate structure and inconvenient use. The door lock between the machines comprises a lock rod, a lock core and a lock body bottom plate; the U-shaped lock rod is fixed on a door frame; the lock body bottom plate is fixed on a door plate and parallelly provided with two mounting seats; the lower end of the mounting seat is provided with a lower fixed pin; the lower fixed pin is sheathed with a positioning rod which can rotate andslide relatively to the lower fixed pin; the positioning rod is sheathed with a compression spring; the upper end of the positioning rod is connected with the lower end of the lock core by a rotatingpin; the two ends of the rotating pin are inserted into a triangular limit frame which is arranged on the mounting seat; the upper end of the mounting seat is provided whit an upper fixed pin which is sheathed with the lock core which can rotate and slide relatively to the upper fixed pin; and the upper end of the lock core is provided with a U-shaped groove which can be clamped on the lock rod. The invention has the beneficial effects that the structure is simplified; the automatically locking performance is increased so as to lead the door lock not to move relatively; the noise is reduced; the structure is compact; and the maintenance is convenient.
