Abstract
The utility model discloses a magneto type electromagnetic door stopper which is used to maintain the normally open status of the door of building and stop the normally open status of the door upon a signal input. The door stopper comprises a sucker disk, a square cover, a T-shaped iron core and an electromagnetic coil. The sucker disk is fixed on the back surface of the door; the electromagnetic coil is suited on the T-shaped iron core; the steel cover, a magnet and the T-shaped iron core are suited on a guide post. The magnet is arranged between the steel cover and the T-shaped iron core. The end of the guide post is pressed against a switching arm of a travel switch; a guard hood is connected outside the steel cover. A steel post is suited in the center of the guard hood. A small spring is suited on the end of the guide post. And a big spring is suited on the steel post which connects with a rear framework. And the rear framework connects with the square cover. By adopting the combination of the permanent magnet and the electromagnet, when the door open state maintains, the door body is sucked through the suction of the magnet without any consumption of electricity. When the power supply is turned on, the electromagnetic coil and the T-shaped iron core form an electromagnetic field to push open the sucker disk and overcome the suction of the magnet, the door can be closed. The power on time is very short which consumes only a little electricity.
Description
Technical field
The utility model relates to a kind of electromagnetism door-inhale of often opening the state of keeping that is used to keep the building door normally open and finishes door when the signal input is arranged.
Background technology
Known electromagnetism door-inhale comprises iron core, coil and sucker.Coil is enclosed within on the iron core, and on wall, sucker is contained in the back side of door to iron core by frame fixation.During coil electricity, iron core produces suction to sucker, makes door maintain the state of opening.This electromagnetism door-inhale is energising all the time during keeping the state of Men Changkai, and power consumption is many, the cost of use height.
Summary of the invention
The purpose of this utility model is the Magnet-type magnetic Door Stopper that a kind of little power consumption will be provided.
The purpose of this utility model is achieved in that this door-inhale comprises sucker, side's cover, T shape iron core and electromagnetic coil; sucker is fixed on the back side of door; electromagnetic coil is enclosed within on the T shape iron core; steel cage, magnetite and T shape iron core sleeve are on guide pillar; magnetite is between steel cage and T shape iron core; the end of guide pillar is pressed on the switch arm of travel switch; the steel cage outside is connected with the protection outer cover; protection outer cover center is with steel column; the guide pillar end is with little spring; be with big spring on the steel column, steel column is connected with afterframe, the afterframe side of being connected with cover.
The utility model adopts permanent magnetism stone and electromagnetic combination, when keeping door opening state, lives the door body by the suction adsorption of magnetite, is in off-position, not consumed power.When power connection, electromagnetic coil and T shape iron core form electromagnetic field, push sucker open, overcome the suction that falls magnetite, and door can be closed.Conduction time is extremely short, and little power consumption has reduced cost of use.
Below in conjunction with drawings and Examples the utility model is elaborated.

The specific embodiment
In Fig. 1; sucker 1 is fixed on the back side of door, and electromagnetic coil 2 is enclosed within on the T shape iron core 3, and steel cage 6, magnetite 5 and T shape iron core 3 are enclosed within on the guide pillar 4; magnetite 5 is between steel cage 6 and T shape iron core 3; the end of guide pillar 4 is pressed on the switch arm of travel switch 8, and steel cage 6 outsides are connected with protection outer cover 7, and protection outer cover 7 centers are with steel column 11; guide pillar 4 ends are with little spring 9; be with big spring 10 on the steel column 11, steel column 11 is connected with afterframe 13, afterframe 13 sides of being connected with cover 12.
Magnetite 5 is an annular, constitutes a magnetic loop with T shape iron core 3 and steel cage 6.When outage, rely on the magnetic force of magnetite 5, sucker 1 is closely inhaled with steel cage 6 with T shape iron core 3 and is in the same place.The diameter dimension and the thickness of magnetite 5, T shape iron core 3, steel cage 6 and sucker 1, and the magnetic flux of magnetite 5 has all determined the size of suction.The change of these sizes makes product can make the different various models of absorption affinity.
T shape iron core 3 is fixedlyed connected with steel cage 6 by bolt.
Leave the gap between protection outer cover 7 and the side's cover 12.Big spring 10 has guaranteed that the center of steel cage 6 integral body is stable.When the angle of the Men Tiyu between the walls that is connected with sucker 1 was spent greater than 0, steel cage 6 in certain scope intrinsic deflection angle, made absorption surface keep closely consistent, very close to each other by protection outer cover 7 compressible big springs 10.
During absorption, sucker 1 is by guide pillar 4 compression little springs 9, and the displacement of guide pillar 4 promotes travel switch 8.
Electromagnetic coil 2 is coils that are wrapped on the plastic skeleton.The thickness of coil and the winding number of turns affect the power of electromagnetic field magnetic force.Electromagnetic coil 2 and T shape iron core 3 have constituted an electromagnetism and have produced body.
In Fig. 2, during energising, the magnetic force direction that the electromagnetic push of generation and magnetite 5 produce is opposite, promotes sucker 1 and breaks away from contacting of steel cage 6 and T shape iron core 3.At this moment guide pillar 4 also can eject under the effect of little spring 9, and travel switch 8 is finished the action of outage and signal feedback.
