Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.

The utility model relates to an electromagnetic lock with shockproof function, as shown in figures 1-3, comprising an outer shell 1, an inner shell 2 and a fan-shaped lock head 3, wherein the two inner shells 2 are arranged in a front-back butt joint way, the outer shells 1 on two sides are spliced to form a rectangular structure with a hollow interior, the upper part of the inner shell 2 is rotatably provided with a fan-shaped lock head 3 with the upper part extending out of the inner shell 2, the rotating shaft part of the fan-shaped lock head 3 is provided with a torsion spring 6 with one end propped against the inner shell 2 and the other end fixed with the fan-shaped lock head 3, a rotatable shockproof plate 5 is vertically arranged in the left part of the inner shell 2, the upper end of the shockproof plate 5 is matched with a gap at the left part of the lower end of the fan-shaped lock head 3, the lower part of the inner shell 2 is transversely provided with an electromagnetic coil 4, the left end of the electromagnetic coil 4 is provided with a spring 9 corresponding to the lower end of the shockproof plate 5, and the spring 9 is provided with an iron core 10 which is propped against the lower end of the shockproof plate 5.

According to the technical scheme, when the electromagnetic lock is unlocked, the electromagnetic coil 4 is electrified to form an electromagnetic effect and suck the iron core 10 and the lower end of the shockproof plate 5, so that the upper end of the shockproof plate 5 is separated from the notch of the fan-shaped lock head 3, and the unlocking operation of the electromagnetic lock is completed.

When the electromagnetic lock is locked, the electromagnetic coil 4 is required to lose power, the iron core 10 pushes the lower end of the shockproof plate 5 under the action of the spring 9, and then the fan-shaped lock head 3 is rotated, so that the notch of the fan-shaped lock head 3 is abutted against the upper end of the shockproof plate 5, and the locking operation of the electromagnetic lock can be completed.
