Abstract

The invention discloses a dual-purpose unlocking and locking mechanism which comprises a frame (1), a manual unlocking assembly (2), a push rod (9) and an electromagnetic locking assembly (13). The frame (1) is provided with the manual unlocking assembly (2) and the electromagnetic locking assembly (13), and the electromagnetic locking assembly (13) is composed of an electromagnet (16) and a torsional spring (18). The dual-purpose unlocking and locking mechanism is characterized in that the manual unlocking assembly (2) comprises a spring sheet (3), a cover plate (4), a pull ring (6) and a pull plate (7), the cover plate (4) is arranged on the outer portion of the spring (5), the spring sheet (3) is arranged on the lower portion of the cover plate (4), the pull ring (6) and the pull plate (7) are in sliding connection, the pull plate (7) is arranged on damping rubber (8), the push rod (9) is arranged on a rotating shaft (11), and the push rod (9) is in sliding fit with an inner ring of an annular support (10). The dual-purpose unlocking and locking mechanism is small in structural unlocking force, and reliable in locking.

Description

technical field [0001] The invention belongs to the technical field of locking devices, and in particular relates to a dual-purpose unlocking and locking mechanism. Background technique [0002] As one of the most common auxiliary mechanisms, locking devices are widely used in aerospace, military, machinery and other industries. In the aviation control mechanism, in order to prevent the push rod from being pulled backward before the aircraft speed drops below the preset required speed, it is necessary to design a reasonable and reliable locking device to prevent misoperation. Common aviation locking devices are generally controlled by electromagnets, which cannot cope with the failure of circuits such as electromagnets. The locking force is small and the unlocking force is large, resulting in poor locking operation reliability and cannot meet today's requirements. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages...
