It is far from being enough for the vehicles frequently used.
Utility model content
The purpose of this utility model is to provide a kind of rational in infrastructure, longer subway safe door electromagnetism of service life
Iron.
To solve above technical problem, the technical solution adopted in the utility model is：A kind of electricity for subway safe door
Magnet, including sequentially connected dust cover, spring, screw, locating ring, outline border, coil, slide bar, noise reduction gasket, iron from top to bottom
Core, dustproof cover；Wherein, the outline border is each provided with a through hole in both sides up and down, and the locating ring is fixed on by the screw
The top of the outline border, the slide bar load the coil inside and the inside into the outline border and extension are installed together with coil
Go out the upper through hole of the outline border, the iron core is installed on the lower part of the outline border, and the end of the iron core extend it is described
Outline border lower through-hole, the mandrel lower connect dustproof cover, and the lower part of the slide bar is arranged the noise reduction gasket and stretches into the iron
Core inner, the contact site of through hole is provided with big bearing on the slide bar and outline border, under the inside of the iron core and slide bar
Portion contact position is provided with small bearing.
Further, the slide bar is the slide bar after QPQ is surface-treated.
In conclusion with the technical solution of the utility model, have the advantages that：The electromagnet of the utility model
By increasing self-lubricating size bearing in the contact site up and down of slide bar, to reduce abrasion so as to improve service life, while
QPQ treatment technologies are used on the surface of slide bar instead, are improved case hardness and are reduced abrasion so as to improve service life.

11st, spring 10, screw 7, locating ring 6, outline border 1, coil 5, slide bar 9, noise reduction gasket 8, iron core 3, dustproof cover 12；Wherein, it is described
Outline border is each provided with a through hole in both sides about 1, and the locating ring 6 is fixed on the top of the outline border 1 by the spiral shell 7 nail,
Locating ring 6 and 11 thread fitting of dust cover, so that dust cover 11 is fixed on outside locating ring 6, spring 10 is arranged at locating ring 6
Between dust cover 11, the slide bar 9 load the inside of the coil 2 and installed together with coil 2 into the outline border 1 inside and
Extend the upper through hole of the outline border 1, the iron core 3 is installed on the lower part of the outline border 1, and the end of the iron core 3 is prolonged
Stretch out 1 lower through-hole of outline border, the lower dustproof cover 12 of 3 lower part of iron core connection, specifically, iron core 3 is up big and down small two
Hollow cylinder is formed, and wherein huge pillar circle blocks 1 lower through-hole of outline border, and small cylinder is stretched out from outline border 1, and small column
End set helicitic texture, with dustproof cover coordinate；The lower part of the slide bar 9 is arranged the noise reduction gasket 8 and stretches into the iron
Inside core 3, the contact site of through hole is provided with big bearing 5 on the slide bar 3 and outline border 1, in the inside of the iron core 3 and cunning
Small bearing 4 is provided with 9 lower contacts of bar.
In one embodiment of the utility model, the slide bar is the slide bar after QPQ is surface-treated.
As shown in Fig. 2, the electromagnet of the utility model, operation principle in the power-off state are：In the effect of spring 10
Under, slide bar 9 moves upwards, and after moving to certain position, dust cover 11 treats spring force and dust cover to the effect of pullling of slide bar 9
Balance of power when, produce off-position as shown in Figure 2.
As shown in figure 3, the electromagnet of the utility model, operation principle in the energized state are：After energization, electromagnet is slided
The dynamic dust cover 11 of bar 9 and noise reduction gasket 8 compress downwards spring 10 and move, and stop fortune after noise reduction gasket 8 and iron core 3 collide
It is dynamic, produce "on" position as shown in Figure 3.
The above is the preferred embodiment of the utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these are improved and profit
Decorations are also considered as the scope of protection of the utility model.
