Vibration-resistant electromagnet

Abstract

The invention discloses a vibration-resistant electromagnet. The vibration-resistant electromagnet comprises a magnet block, an upper clamping ring, a spring, a slide rod, a first cover plate, a second cover plate, a coil, a shell, an iron core, an ejector pin and a lower clamping ring, wherein the magnet block, the upper clamping ring, the spring, the slide rod, the first cover plate, the secondcover plate, the coil, the shell, the iron core, the ejector pin and the lower clamping ring are connected in sequence from top to bottom. A spiral groove is formed in the lateral side of the slide rod, and lugs matched with the spiral groove are arranged at a through hole of the second cover plate. When the electromagnet vibrates, the spiral groove in the lateral side of the slide rod makes contact with the lugs, and inverted repulsion is generated, so that the slide rod is prevented from continuing to move downwards. When the electromagnet vibrates in a power-off state, the spiral groove inthe lateral side of the slide rod instantaneously makes contact with the lugs on the inner side of the cover plate, and the inverted repulsion is generated, so that the slide rod is prevented from continuing to move downwards. When an original electromagnet suffers from instantaneous axial external impact force, the spring can be compressed to retract, so that an unlocking problem is generated, but the problem is solved by means of the vibration-resistant electromagnet.

Description

technical field [0001] The invention relates to an anti-seismic electromagnet used for a shared power bank cabinet. Background technique [0002] Existing electromagnets used for shared charging treasure cabinets are kept in the maximum exposed self-locking state under the action of spring force after power failure. When subjected to an instantaneous axial impact external force, the spring will be compressed and retracted, resulting in unlocking and poor safety. . Contents of the invention [0003] The object of the present invention is to provide a shockproof electromagnet with good safety and self-locking function. [0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: an anti-vibration electromagnet, including a magnetic block connected in sequence from top to bottom, an upper collar, a spring, a slide bar, a first cover plate, a second cover plate, Coil, casing, iron core, push rod, lower collar, wherein, ...
