Lid locking mechanism

Abstract

The invention discloses a box cover locking mechanism which comprises a spring bolt and a lock body. The lock body comprises a base plate and a front cover plate, wherein a horizontal groove is formed in the base plate, a pulling rod is arranged in the horizontal groove, a perpendicular guide groove is formed in the position, above the horizontal groove, of the base plate, the perpendicular guide groove comprises a first conical groove, a rectangular groove and a second conical groove, the first conical groove, the rectangular groove and the second conical groove are sequentially connected from top to bottom, the first conical groove gradually shrinks from top to bottom, the second conical groove is gradually expanded from top to bottom, a sliding block, a left lock hook and a right lock hook are arranged in the perpendicular guide groove, and the upper end of the left lock hook and the upper end of the right lock hook are respectively provided with a hook body. The lower end of the left lock hook and the lower end of the right lock hook are hinged to the sliding block, a spring is arranged between the lower end of the left lock hook and the lower end of the right lock hook, an actuation rod is arranged between the lower end of the sliding block and the middle of the pulling rod, the upper end of the spring bolt is an installation end for being fixed on the box cover, a boss is arranged at the lower end of the spring bolt, the boss is arranged between the left lock hook and the right lock hook and clamped on the hook bodies of the upper end of the left lock hook and the upper end of the right lock hook, and the front cover plate is fixed on the surface of the base plate. The box cover locking mechanism is compact in structure, large in locking force, and small in space required by operation.

Description

technical field [0001] The invention relates to a locking mechanism, in particular to a locking mechanism for a box cover. Background technique [0002] The launch box cover of the launch platform needs a locking mechanism to lock it, and the locking mechanism needs to be able to automatically open and close under the drive of the actuator.
