Push-and-pull electromagnet

Abstract

The invention provides a push-and-pull electromagnet. A center pole passing through an outer frame is arranged on the central spindle of a movable iron core; one end of the center pole is a telescopicworking end, and the other end of the center pole is a limiting end for thrust limiting; a rotary disc is arranged on the working end in a sleeving manner; the rotary disc is movably connected with the outer frame; a spiral inner ball groove is formed in the axle hole of the rotary disc, and a corresponding outer ball groove is formed in the working end; stainless steel balls are matched betweenthe inner ball groove and the outer ball groove; a tapered head is arranged on the rotary disc; the movable iron core telescopes to drive the rotary disc to rotate, and the tapered head rotates aroundthe working end; a reset spring is further arranged on the limiting end in a sleeving manner; a sliding ring is further arranged on the limiting end in the sleeving manner; the reset spring acts between the outer frame and the sliding ring; the sliding ring and the outer frame are articulated through two connecting rods; the two connecting rods are a first connecting rod and a second connecting rod respectively; one end of the first connecting rod is articulated onto the outer frame, and the other end of the first connecting rod is articulated to one end of the second connecting rod; and theother end of the second connecting rod is articulated onto the sliding ring.

Description

technical field [0001] The invention relates to the field of electromagnet structure, in particular to a push-pull electromagnet. Background technique [0002] An electromagnet is a device that generates electromagnetism when energized. After inserting an iron core inside the coil, the iron core is magnetized by the magnetic field of the coil. The electromagnets on the market usually include a bracket, a coil and a telescopic rod. The bracket is fixedly connected to the coil. There are through holes on the bracket. The telescopic rod includes a push rod and a top sleeve. The setting of the through hole makes it easy for the electromagnet to enter impurities and water from the through hole during use. The impurities include oil stains, dust, etc. The water will accelerate the corrosion and rust of the moving parts. The impurities and rust will affect the smooth movement of the moving parts. Ultimately, the electromagnet cannot work normally, so it needs to be dismantled and ...

The electromagnets on the market usually include a bracket, a coil and a telescopic rod. The bracket is fixedly connected to the coil. There are through holes on the bracket. The telescopic rod includes a push rod and a top sleeve. The setting of the through hole makes it easy for the electromagnet to enter impurities and water from the through hole during use. The impurities include oil stains, dust, etc. The water will accelerate the corrosion and rust of the moving parts, and the impurities and rust will affect the smooth movement of the moving parts. Ultimately, the electromagnet will not work properly, requiring disassembly and replacement, wasting manpower and resources
