Abstract

The invention relates to a dual spring electromagnet with a manual unlocking structure. The dual spring electromagnet comprises an electromagnet body and the manual unlocking structure. The manual unlocking structure comprises an unlocking seat, an unlocking sliding block, a retention spring and a spring seat. The unlocking seat and the unlocking sliding block are sequentially mounted on a core shaft in a sleeving manner and are in clearance fit with the core shaft, and the unlocking seat and a base are fixedly connected. A convex block is arranged at the end, close to the unlocking sliding block, of the unlocking seat. An unlocking groove is formed in the end, close to the unlocking seat, of the unlocking sliding block. Under the condition that the electromagnet is locked, the unlocking groove is matched with the convex block, and the convex block is located in the unlocking groove. Under the condition that the electromagnet is unlocked manually, the end face of the end, provided withclamping grooves, of the unlocking sliding block abuts against the convex block, and the unlocking state is kept. The spring seat is arranged on the outer side of the unlocking sliding block and is fixedly connected with the core shaft. The dual spring electromagnet solves the technical problems that the existing electromagnet manual unlocking efficiency is low, threads are prone to being worn, and the falling risk happens to nuts under the vibration condition.

Description

technical field [0001] The invention relates to a double-spring electromagnet, in particular to a double-spring electromagnet with a manual unlocking function. Background technique [0002] The electromagnet is a pin-type brake device with power-on disengagement (release) and power-off spring brake. It has the advantages of compact structure, convenient installation, wide adaptability, low noise, sensitive action, and reliable braking. It is used as power-off brake, Locking devices are widely used in electromechanical equipment in aviation, aerospace and other fields. The existing manual unlocking of the electromagnet is realized by a bolt-nut structure, and the linear parallel movement of the bolt is exchanged for the rotational movement of the nut, thereby realizing the unlocking. [0003] The existing electromagnets with a bolt-nut manual unlocking structure have the following problems: [0004] 1. The unlocking can only be realized by turning the nut several times, the...
