Abstract
The utility model discloses an electromagnet structure. On the basis of the conventional electromagnet structure, a piston and a cushioning cylinder are respectively arranged at the bottom of a moving iron core and the bottom, opposite to the central position of the bottom of a static iron core, of the bottom of the moving iron core; the aim of cushioning is fulfilled by a damping effect when the piston enters the cushioning cylinder. The electromagnet structure has the advantages of low noise, low vibration and long service life.
Description
Technical field
The utility model relates to a kind of structure of electromagnet, belongs to the electrotechnical elements technical field.
Background technology
Electromagnet is a kind of common electrotechnical elements, existing electromagnet generally comprises coil rack, coil static iron core and moving iron core, after coil electricity, moving iron core is produced to attraction, thereby realize the purpose of work, existing electromagnet is because moving iron core is to be in the centre bore that free state is placed in coil rack, so produce larger impulsive force when the moment of moving iron core adhesive, thereby produce larger noise, be unfavorable for the protection of environment. in addition, this impulsive force also can cause the vibration with other electric elements of an installation of electromagnet, easily cause the damage of other electric elements.
Summary of the invention
The purpose of this utility model is: the above-mentioned defect existed for existing electromagnet, the utility model provides a kind of new electromagnet, overcomes the existing existing above-mentioned defect of electromagnet.
The utility model realizes that the technical scheme that above-mentioned purpose adopts is: the structure of described a kind of electromagnet, comprise: moving iron core, coil rack, coil, piston, sealing ring, cushion dashpot, static iron core, coil rack is arranged on the centre position of static iron core, the some turn coil of coiling on the cylindrical of coil rack, described moving iron core is arranged in the middle sky of coil rack, bottom centre position at moving iron core is provided with piston, be shaped with outer guide cone on the cylindrical of the lower end of described piston, on the outside piston near the guide cone position, sealing ring is installed, be provided with cushion dashpot on static iron core under piston, the limit port part of described cushion dashpot is shaped with outer guide cone.
The course of work of the present utility model is such: when moving iron core moves downward with respect to static iron core under the attraction of electromagnetic force, result due to the outer guide cone mutually aligned and the mutual guide effect of interior guide cone, piston inserts in the endoporus of cushion dashpot, and at the instantaneous atmospheric pressure of setting up, relief hole discharges the air pressure in cushion dashpot gradually, makes the iron core impulsive force obtain gradually release.
The accompanying drawing explanation:
Accompanying drawing 1 is structure principle chart of the present utility model;
Shown in Fig. 1: 1, moving iron core; 2, coil rack; 3, coil; 4, piston; 5, sealing ring; 6, cushion dashpot; 7, static iron core; 8, outer guide cone; 9, interior guide cone; 10, relief hole.
Embodiment
A kind of structure of electromagnet, comprise: moving iron core 1, coil rack 2, coil 3, piston 4, sealing ring 5, cushion dashpot 6, static iron core 7, coil rack 2 adopts the nonmetallic materials manufacture, it is arranged on the centre position of static iron core 7, the some turn coil 3 of coiling on the cylindrical of coil rack 2, moving iron core 1 is arranged in the middle sky of coil rack 2, bottom centre position at moving iron core 1 is provided with piston 4, be shaped with outer guide cone 8 on the cylindrical of the lower end of piston 4, on piston 4 cylindricals near outer guide cone 8 positions, sealing ring 5 is installed, be provided with cushion dashpot 6 on static iron core 7 under piston 4, be shaped with outer guide cone 9 at the limit of cushion dashpot 6 port part, be shaped with less direct micro-hole relief hole 10 in the bottom of cushion dashpot 6.
