[0006] In order to achieve the above object, the technical scheme adopted by the utility model is: emergency stop switch protection device, including cover in the outer periphery of emergency stop switch Cover body is circular tube shape structure matched with the shape of emergency stop switch, cover body is made of polycarbonate material, the lower end of cover body is provided with magnetic adsorption mechanism for fixing cover body.

[0007] Based on the above, the magnetic adsorption mechanism comprises at least two circumferential array arrangements and is integrally injection molded with the outer circumference of the lower end of the cover body, the lower end of the lug is flush with the lower end of the cover body, the bottom of the lug is provided with an open lower receiving groove, and the strong magnetic block is matched and embedded in the receiving groove.

[0008] Based on the above, the inner side wall of the receiving groove is provided with a plurality of clamping grooves, and the outer surface of the strong magnetic block is integrally formed with a plurality of protrusions, each protrusion corresponds to each clamping groove and is clamped and matched.

[0009] Based on the above, the strong magnetic block is made of a neodymium iron boron magnet.

[0010] Compared with the prior art, the utility model has substantial features and progress, specifically, the cover body of the utility model covers the outer periphery of the emergency stop switch, and the cover body is made of polycarbonate material, the cover body has high transparency, can conveniently observe the state of the emergency stop switch, can prevent external objects from directly contacting the emergency stop switch, avoids the emergency stop switch from being mistakenly touched, protects the emergency stop switch from being eroded by external pollutants such as dust, water vapor and oil stains, and prolongs the service life of the emergency stop switch. And the cover body has good protection performance and impact resistance, can adapt to harsh industrial environments, and provides strong guarantee for the safe operation of industrial equipment. The outer circumference of the lower end of the cover body is integrally injection molded with a plurality of lug seats, the bottom of the lug seat is provided with a receiving groove, a strong magnetic block is matched and embedded in the receiving groove, and the cover body is conveniently and firmly adsorbed and installed on the case of the equipment. The overall structure is simple, economical and applicable.

[0011] Further, the inner side wall of the receiving groove is provided with a clamping groove, the outer surface of the strong magnetic block is provided with a protrusion matched and clamped with the clamping groove, and the strong magnetic block is firmly and reliably installed.
