Explosion-proof magnetic chuck

Abstract

The invention discloses an explosion-proof magnetic chuck comprising an insulation jacket; the insulation jacket is provided with an inner chamber therein; one end of the insulation jacket is open and the other end is closed; the open end of the insulation jacket is provided with an annular sleeve; the other end of the annular sleeve is provided with a fixed magnetic steel. According to the invention, the device is installed by magnet through attraction; since static is on ferruginous objects, the overall device is fixed by means of the feature of magnetic steel, which is convenient to mount and dismount. In the invention, the conductive thimble and the conductive push rod are under the top pressure state under the action of the top tension spring; when the magnet is fixed on the iron object, the thimble will be pressed against the surface of the iron object to ensure contact with the object; the thimble has certain piercing ability and can pierce the paint or rust barrier to effectively relieve static electricity and reduce safety hazards.

Description

technical field [0001] The invention relates to safety facilities and equipment, in particular to an explosion-proof magnetic chuck. Background technique [0002] In flammable gas, dust environment, oil refinery, petrochemical plant, gas station, gas station and other environments where explosion may occur, static electricity will be generated and accumulated arbitrarily, if the accumulated static electricity cannot be channeled, it will have very serious consequences; the existing Explosion-proof chucks used to discharge static electricity usually use wires to guide static electricity to the ground, but the chucks used for fixing existing devices are usually clamped and fixed by chucks with crocodile mouth structure, and the other end of the chuck can be connected to wires. The equipment fixing method of this structure is troublesome and has great limitations. In some special environments, the chuck may not be able to be used; and if there is rust or paint on the column wit...

Problems solved by technology

[0002] In flammable gas, dust environment, oil refinery, petrochemical plant, gas station, gas station and other environments where explosion may occur, static electricity will be generated and accumulated arbitrarily, if the accumulated static electricity cannot be channeled, it will have very serious consequences; the existing Explosion-proof chucks used to discharge static electricity usually use wires to guide static electricity to the ground, but the chucks used for fixing existing devices are usually clamped and fixed by chucks with a crocodile mouth structure, and the other end of the chuck can be connected to a wire. The equipment fixing method of this structure is cumbersome and has great limitations. In some special environments, the chuck may not be used; and when there is rust or paint on the column with static electricity, the chuck After the head is clamped, it cannot be in direct contact with the electrostatically charged part, so there will be a great potential safety hazard
