Abstract
The utility model relates to an electromagnet. Electromagnetic coils are wound in an electromagnetic static iron core, telescopic movable iron cores are arranged in a middle hole of the electromagnetic static iron core, each telescopic movable iron core consists of a plurality of movable joints, the movable joints different in diameters are mutually sheathed together, and a spring is arranged between two connected telescopic movable iron cores. The electromagnet has the advantages that the purpose of extending the action distance of the electromagnet is realized, and the electromagnet is suitable for the use requirements of some special occasions.
Description
Technical field
The utility model relates to a kind of electromagnet, belongs to the electric elements technical field.
Background technology
At present, the moving iron core of existing electromagnet is all the version of an integral body, because the length of the moving iron core of the structure of this integral body is generally all shorter, so what the iron core of electromagnet can act on is limited in scope, in the situation that some are special, because the sphere of action of moving iron core is too short, can't adapts to some special occasions and use, for example: require iron core can the go directly inside of member, simultaneously, iron core does not consist of interference to other parts again; For another example: require the iron core of electromagnet can touch the travel switch of distant place, other parts are not brought again the situation of interference simultaneously, so existing electromagnet can't reach above-mentioned requirements.
Summary of the invention
The purpose of this utility model is: can't satisfy some special occasions for existing electromagnet and use, especially requirement has the defective of the workplace use of operating distance far away, and the utility model provides a kind of novel electromagnet.
A kind of electromagnet described in the utility model, it comprises electromagnetism static iron core, solenoid, the moving iron core of expansion joint type, spring, it is characterized in that, described electromagnetism static iron core is to have the good material of permeability magnetic material to make, be wound with solenoid in the electromagnetism static iron core, be provided with the moving iron core of casing coupling formula in the interstitial hole of electromagnetism static iron core, the moving iron core of described casing coupling formula is comprised of the active section that some the diameter that connect together each other differ, and between the moving iron core of two the casing coupling formulas that are connected, spring is set.
Beneficial effect: the utility model by the moving Telescopic of iron core under spring and electromagnetic force of casing coupling formula, reaches the purpose of the operating distance that extends electromagnet due to after adopting said method, can adapt to the instructions for use of some special occasions.
Description of drawings
Accompanying drawing 1 is structure principle chart of the present utility model.
Shown in figure: 1, electromagnetism static iron core; 2, solenoid; 3, the moving iron core of expansion joint type; 4, spring.
