Abstract
The utility model discloses an electromagnet for a subway platform screen door. The electromagnet comprises a magnet yoke and is characterized in that a coil is arranged in the magnet yoke, an armature is connected with a push rod, one end of the push rod extends into the magnet yoke, the other end of the push rod is positioned outside the magnet yoke, one end of the push rod extends into the magnet yoke to be connected with the push rod, the other end of the push rod is positioned outside the magnet yoke, a compression spring is sleeved on the armature, a baffle ring is sleeved on the armature and is positioned outside the magnet yoke, and the compression spring is arranged between the baffle ring and the magnet yoke. According to the electromagnet for the subway platform screen door, the armature and the push rod are reset by using an elastic force of the spring, the adverse effect caused by residual magnetism of the electromagnet is overcome. The accuracy of the action of the armature and the push rod can be improved by adopting a DU bearing, and the subway platform screen door is efficiently driven. The electromagnet provided by the utility model has the advantages of convenience and safety in use, and capability of improving safety factor of the subway platform screen door and preventing people from being hurt.
Description
Technical field
The utility model relates to a kind of subway shield door and uses electromagnet.
Background technology
Subway shield door concerns numerous passengers' safety.For increasing coefficient of safety, adopt shield door can prevent the danger of falling track.But then, the subway shield door of available technology adopting, there is hysteresis phenomenon in electromagnet because remanent magnetism often causes and can't in time reset.Both influenced the efficient of switch door, and also increased the extruding passenger or other unexpected risks take place.
The utility model content
The purpose of the utility model is in order to overcome deficiency of the prior art, to provide the high subway shield door of a kind of efficiency of movement to use electromagnet.
For realizing above purpose, the utility model is realized through following technical scheme:
Subway shield door is used electromagnet, comprises yoke, it is characterized in that, is provided with coil in the yoke; Armature is connected with push rod, and push rod one end stretches in the yoke, and the other end is positioned at outside the yoke; Push rod one end stretches in the yoke and is connected with push rod, and the other end is positioned at outside the yoke, is set with the compression spring on the armature; Be set with back-up ring on the armature; Back-up ring is positioned at outside the yoke, and the compression spring is between back-up ring and yoke.
Preferably, also comprise Capsule, said Capsule is arranged on the yoke, and the compression spring is arranged in the Capsule.
Preferably, described armature and push rod are arranged on the yoke through a DU bearing respectively movably.
Preferably, be provided with buting iron in the described yoke, said buting iron is positioned on the moving line of armature.
Subway shield door in the utility model is used electromagnet, utilizes the elastic force of spring that armature and push rod are resetted, and has overcome electromagnet remanent magnetism adverse effect.Adopt the DU bearing can improve armature and the accuracy that push rod moves, guarantee its Kai Heguan of iron gate drivingly expeditiously.The utility model is easy to use, and safety can improve the coefficient of safety of subway shield door, prevents to crush.
Description of drawings
Fig. 1 partly cuts open figure for the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is carried out detailed description:
As shown in Figure 1, subway shield door is used electromagnet, comprises yoke 10.Be provided with coil 7 in the yoke 10.Armature 1 is installed on the yoke 10 through a DU bearing 6 movably.Armature 1 one ends stretch in the yoke 10, and the other end is positioned at outside the yoke 10.Armature 1 is provided with back-up ring 2.Back-up ring 2 is positioned at outside the yoke 10.Be provided with compression spring 3 between back-up ring 2 and the yoke 10.Compression spring 3 is arranged in the Capsule 4.Capsule 4 is connected with yoke 10.Push rod 13 is arranged on the yoke 10 through the 2nd DU bearing 8 movably.Push rod 13 1 ends stretch in the yoke 10, and the other end is positioned at outside the yoke 10.Push rod 13 1 ends stretch in the yoke 10 and are connected with armature 1.Be provided with buting iron 9 in the yoke 10.Buting iron 9 is positioned on the moving line of armature 1, be used to prevent armature 1 moved the position.
Embodiment in the utility model only is used for the utility model is described, and does not constitute the restriction to the claim scope, and other substituting of being equal in fact that those skilled in that art can expect are all in the utility model protection range.
