Abstract
The utility model discloses an automatic closing device for a fireproof door. The automatic closing device for the fireproof door comprises a spring, a sliding base, a temperature sensing glass ball, an installation frame and an ejector rod, wherein the installation frame can be installed on a door frame, and the ejector rod is connected with the fireproof door. One end of the temperature sensing glass ball is connected to the sliding base and the other end of the temperature sensing glass ball is connected to the installation frame. The sliding base slides in the installation frame in a sliding mode. The ejector rod is arranged on the sliding base. One end of the spring abuts against the installation frame, the other end of the spring abuts against the sliding base, and therefore when a fire occurs and the temperature sensing glass ball is broken, the spring drives the sliding base to slide relative to the installation frame. By the adoption of the automatic closing device for the fireproof door, when a fire occurs, the fireproof door can be automatically closed, so that the fire is prevented from spreading; in addition, the response is sensitive, and the fireproof door is closed rapidly.
Description
Technical field
The utility model relates to a kind of labeled door door engine.
Background technology
At present, labeled door is widely used in warehouse, bank, hotel etc., and some need in fireproof department, and when fire occurs, labeled door should be closed in time, cuts off fiery road, to stop fire spreading.At present, a kind of labeled door with calutron of the many employings of people, at ordinary times, the door-plate of this door is fixed on electromagnet on wall behind the door and attracts and be opening, once breaking out of fire, the related detection device of scene of fire will Xiang Fang fire center give the alarm, as long as operator on duty is the fireproof door electromagnetic iron dump in fire place, the door-plate of labeled door will lose electromagnetic attraction and the automatic door-closing by being contained in the pulling force of the spring hinge on door.The advantage of this door is be convenient to carry out centralized Control and control at a distance, but shortcoming is to control to complete by people, if scene of fire nobody or operator on duty's negligence, all may make labeled door not close in time and causes increasing loss.
Summary of the invention
Technical problem to be solved in the utility model is the defect that overcomes prior art, and a kind of labeled door door engine is provided, and it can make labeled door automatic door-closing when breaking out of fire, to avoid fire spreading, and is quick on the draw, and closes the door rapidly.
The utility model solves the problems of the technologies described above the technical scheme of taking: a kind of labeled door door engine, it comprises spring, slide, temperature sensing glass ball and the push rod that can be arranged on the installing rack on doorframe and be connected with labeled door, one end of temperature sensing glass ball is connected on slide, the other end is connected on installing rack, slide cunning fits in installing rack, push rod is arranged on slide, one end and the installing rack of spring connect, and the other end and slide connect and drive slide to slide with respect to installing rack while breaking with convenient breaking out of fire temperature sensing glass ball.
Further, for the distance that makes push rod connect labeled door can regulate, to reach best door closing speed and reaction speed, on described slide, be provided with nut, described push rod is screw rod, and described screw rod is threaded connection on nut.
The frame mode that connects temperature sensing glass ball between a kind of slide and installing rack is further provided, on described slide, be provided with first sheet, on described installing rack, be provided with second sheet, one end of described temperature sensing glass ball is bearing on first sheet, and the other end is bearing on second sheet.
Further for convenient, be connected with doorframe, described installing rack comprises doorframe Connection Block and mount pad, and doorframe Connection Block is fixedly connected with mount pad, and has the connecting hole for connecting on doorframe Connection Block.
Adopted after technique scheme, when breaking out of fire, when interior temperature rises to uniform temperature, temperature sensing glass ball will break, thereby under the elastic acting force of spring, makes slide drive push rod to slide in installing rack, thereby drive labeled door to close the door in time, avoided fire spreading, so just can when breaking out of fire, make labeled door automatic door-closing, to avoid fire spreading, and be quick on the draw, close the door rapidly, do not need manual control, very convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of labeled door door engine of the present utility model;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
For content of the present utility model is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail below.
As shown in Figure 1, 2, a kind of labeled door door engine, it comprises spring 1, slide 2, temperature sensing glass ball 3 and the push rod 5 that can be arranged on the installing rack 4 on doorframe and be connected with labeled door, one end of temperature sensing glass ball 3 is connected on slide 2, the other end is connected on installing rack 4, slide 2 is sliding to be fitted in installing rack 4, push rod 5 is arranged on slide 2, one end of spring 1 and installing rack 4 connect, and the other end and slide 2 connect and drive slide 2 to slide with respect to installing rack 4 while breaking with convenient breaking out of fire temperature sensing glass ball 3.
For the distance that makes push rod 5 connect labeled door can regulate, to reach best door closing speed and reaction speed, as shown in Figure 1, on slide 2, be provided with nut 6, push rod 5 is screw rod, described screw rod is threaded connection on nut 6.The length of can adjusting screw(rod) stretching out slide 2 by rotary screw, thus the distance that connects labeled door regulated.
As shown in Figure 1, be provided with first sheet 2-1 on slide 2, be provided with second sheet 4-3 on installing rack 4, it is upper that one end of temperature sensing glass ball 3 is bearing in first sheet 2-1, and the other end is bearing on second sheet 4-3.
