Abstract
The utility model discloses an emergency safety door, comprising a door body, a control circuit and a pulley. The door body is installed in a doorframe providing with a slide groove. The pulley is fixed at the edge of the door body and makes the door body sliding in the slide groove. A permanent magnet is installed at one side of the door body. An electric magnet is installed at the position of the doorframe corresponding to the permanent magnet. A coil is wrapped on the electric magnet. The coil is connected with two constantly opened contacts of a single-pole double-throw relay. The two constantly opened contacts are respectively and correspondingly connected with the anode and the cathode of the direct current power supply. Two constantly closed contacts of the single-pole double-throw relay are respectively and correspondingly connected with the cathode and the anode of the direct current power supply. The relay coils of the two constantly closed contacts of the single-pole double are respectively connected with a switch or a sensor. The emergency safety door is realized basing on the principle of electromagnetic induction and is simple in structure, economical and practical property, high in functional reliability and convenience in generalizing and using in broad area.
Description
Technical field
The utility model relates to a kind of safety door, particularly a kind of emergency safety door based on electromagnetic induction principle.
Background technology
In public arenas such as commercial building, hotel, restaurants, timely evacuation crowd's consideration during for the generation emergency except the door of usual use, also requires to be provided with independent safety door.But at present people also are not very well to the understanding of safety door effect, usually safety door one have been locked it, make safety door can not bring into play due effect, and what breed a tragedy thus quite a fewly sees.For example not long ago just reported a restaurant in somewhere because the restaurant manager does not hand over the meal expense to slip away from escape way for preventing client on the TV, safety door is firmly pinned big lock and a chain lock with one, cause the restaurant because liquid gas storage tank is blasted, personnel can't in time evacuate when causing fire, cause the tragedy of 37 people's death.For avoiding the generation once again of this type of tragedy, people press for a kind of novel emergency safety door.This kind safety door should be accomplished guarantee to pin at ordinary times, in case can open easily when being in an emergency.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of novel emergency safety door.This safety door designs according to electromagnetic induction principle, can accomplish guarantee to pin at ordinary times, in case can open easily when being in an emergency.
For this reason, the utility model adopts following technical scheme:
A kind of emergency safety door comprises a body, control circuit, pulley, and the door body is installed within the doorframe that chute is housed, and pulley is fixed on the edge of a body, and a body can be slided in chute, it is characterized in that:
One side of described door body is equipped with permanent magnet, with the corresponding doorframe of described permanent magnet position electromagnet is installed, be wound with coil on the described electromagnet, this coil is connected with the constant open contact of two single-pole double throw relays, these two constant open contacts respectively be connected corresponding of anode of dc source with negative electrode; The constant close contact of these two single-pole double throw relays respectively be connected corresponding of negative electrode of this dc source with anode, their relay coil connects switch or sensor respectively.
Emergency safety door described in the utility model realizes that based on electromagnetic induction principle simple in structure, economical and practical, the functional reliability height is convenient to large tracts of land and is promoted the use of.
Description of drawings
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is described further.
Fig. 1 be should anxious safety door structure chart.
Fig. 2 be should anxious safety door circuit theory diagrams.
The specific embodiment
Should form by door body, control circuit, magnet, pulley etc. by anxious safety door.This safety door adopts the form of structure of sliding door, and the door body is positioned at doorframe 1, and doorframe 1 is fixed in the body of wall.Be separately installed with the chute 2 of the glide direction that is used for fixing door in the both sides up and down of doorframe.Corresponding with this chute, at the two ends up and down of door body pulley is installed, pulley by screw at door body edge.Certainly, only side installation chute also is fine below doorframe, and corresponding, pulley only is installed in the lower end of a body.
As shown in Figure 1, main innovation part that should anxious safety door is the side mounting permanent magnet at the door body, and electromagnet is being installed with the corresponding doorframe of permanent magnet position, the coil that twines on the electromagnet as shown in Figure 2, insert the constant open contact of two single-pole double throw relay K 1 and K2 respectively, these two constant open contacts are connected with negative electrode with the anode of a 12V dc source respectively, form a current loop.The constant close contact of K1 and K2 also is connected with anode with the negative electrode of this 12V dc source respectively, thus form one with above-mentioned current loop in another current loop of current opposite in direction.The relay coil L of K1 and K2 is connected with sensor C with switch S P respectively, and this switch S P and sensor C always are in the state of shutoff when flat.When K1 and K2 are positioned at the state of constant open contact, K1 and K2 make the polarity of this electromagnet and permanent magnet just in time opposite with the current loop that winding magnet spool, dc source form, according to the principle that the magnet same sex is repelled each other, there is a natural attraction between the sexes, suction between electromagnet and the permanent magnet can make this body be fixed on the doorframe firmly at this moment, if we do not open with manpower by controlling current strength and magnet quantity so that the magnetic force of magnet is enough strong at all.And in case when being in an emergency, above-mentioned switch S P is pressed, relay coil begins charging, and K1 and K2 turn to the state of constant close contact after a period of time, causes the sense of current that twines in the magnet spool to change.According to the basic principle of electromagnetic induction, the polarity of electromagnet will take a turn for the worse, and the repulsion between the magnet will make this safety door be opened like a cork.
In the utility model, this sensor can be the polytype sensor of situations such as temperature sensor, smog.When it sensed abnormal conditions, this circuit is connected, and was in full accord when action of relay thereafter and switch S P are pressed, and so should also can easily be opened by anxious safety door.
In actual applications, can use a plurality of sensors, each sensor is connected in parallel.Any one sensor sensing is after abnormal conditions, and emergency safety door all can in time be opened, thereby the tragedy of avoiding people to escape takes place.
What need statement is; particular of the present utility model is described in detail the utility model; for a person skilled in the art, all will be within protection domain of the present utility model in the various conspicuous change of under the situation that does not deviate from spirit and scope of the present utility model it being carried out.
