At present, professional personnel and professional equipment are needed to open the deformed safety door, so that people escape and fire fighters are rescued, and the life and work safety of people is seriously affected.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that the shortcoming to prior art provides a fire emergency exit with strong function of opening for need not the emergency exit that just can open with the help of professional instrument and personnel in the extreme condition.
For solving the technical problem of the utility model adopt the following technical scheme:
the utility model provides a fire emergency exit with open function by force, includes the door body, door body one side hinge joint connector, the door body is the vertical state with the connector when closing, connector and wall body are fixed, the connector includes the transmission sleeve, transmission sleeve one end is articulated with door body one side, the telescopic other end suit secondary drive axle of transmission, the threaded end and the internal thread looks adaptation of transmission sleeve of secondary drive axle, the secondary drive axle passes through conical gear group and is connected with first transmission shaft, first transmission shaft is connected with the speed reducer.
The end part of the transmission sleeve connected with the door body is provided with a clamping groove, the door body is provided with a limiting sheet, and the clamping groove is matched with the limiting sheet to realize the limiting of the door body.
The door body is provided with an upper cable for restraining the door body when the door body is broken, the cable is wound on the winding disc, and a main shaft of the winding disc is connected to the wall body through a rotary damper.
The speed reducer is embedded into a wall body, a base is arranged in the wall body, and the first transmission shaft and the second transmission shaft are sleeved in the base.
And a liquid nitrogen tank is arranged in the wall body and is communicated with the liquid guide pipes which are arranged in a snake shape in the door body.
The speed reducer is connected with the UPS power supply.
The utility model discloses a fire control emergency exit with open function by force is provided with the connector of fixing on the wall body, under emergency exit normal conditions, fixed emergency exit and with the emergency exit articulated effect that plays the emergency exit and open and shut. Under the condition that the safety door cannot be opened due to high-temperature deformation, the speed reducer is started to drive the first transmission shaft to rotate, the first transmission shaft drives the second transmission shaft to rotate, and the threaded end of the second transmission shaft and the internal thread of the transmission sleeve form a screw rod, so that the transmission sleeve moves outwards to break a door body, and the danger that the fireproof safety door cannot be opened under the extreme condition is solved. Meanwhile, a winding disc and a cable are arranged between the door body and the wall body, and the winding disc and the cable are used for restraining the door body when the door body is broken and preventing the door body from falling down suddenly to hurt people. And a liquid nitrogen cooling system is also arranged, and the liquid nitrogen is used for rapidly cooling the door body to freeze and cool, so that the rigidity and toughness of the door body are reduced, and the door body becomes brittle and is beneficial to breaking.

fig. 2 is a partial schematic view of the present invention.
Detailed Description
The technical solution of the present invention is explained in detail below, but the scope of protection of the present invention is not limited to the embodiments.
As shown in fig. 1 and fig. 2, the utility model discloses a fire emergency exit with function is opened by force, including the door body 1, the connector is articulated to door body 1 one side, and under emergency exit normal condition, the connector is used for the emergency exit to normally close. When the door body 1 is closed, the door body is vertical to the connector, and the connector is fixed on a wall body at the side edge of the door body 1. The connector comprises a transmission sleeve 9, a clamping groove 21 is formed in the end portion of one side of the transmission sleeve 9 and matched with a limiting piece 22 fixed on the door body 1, the limiting piece 22 is in a quarter-circle shape, the inner contour of the clamping groove 21 is a semicircular groove matched with the outer contour of the limiting piece 22, and the limiting piece 22 is inserted into the clamping groove 21 to limit the degree of freedom of rotation of the door body 1. The inner wall of the other side of the transmission sleeve 9 is provided with threads and is connected with a second transmission shaft 5, two groups of transmission sleeves 9 are arranged on the door body 1 from top to bottom, and the other ends of the second transmission shafts 5 arranged from top to bottom are inserted into the base 2 and fixed. A speed reducer 3 is arranged in a wall body at the top of the base 2, and the speed reducer 3 is connected with a UPS (uninterrupted power supply) 19. The output shaft coaxial coupling of speed reducer 3 has first transmission shaft 4, and in base 2 was located to the vertical direction of first transmission shaft 4, two second transmission shafts 5 that horizontal direction was arranged from top to bottom in first transmission shaft 4 passed through conical gear group 7 drive base 2. When a fire disaster causes the door body 1 to deform and cannot be opened, the speed reducer 3 is started to drive the first transmission shaft 4 to rotate, the first transmission shaft 4 drives the second transmission shaft 5 to rotate, the threaded end of the second transmission shaft 5 and the internal thread of the transmission sleeve 9 form a screw rod, the transmission sleeve 9 is driven to move outwards to further burst the door body 1, and the danger that the fireproof safety door cannot be opened under the extreme condition is solved.
One end of a cable on the door body 1 is used for restraining the door body 1 when the door body 1 is broken, the cable is wound on a winding disc 10, and a main shaft of the winding disc 10 is connected to a wall body through a rotary damper 11. The door body 1 is restrained when the door is broken, and the door body 1 is prevented from falling down suddenly to hurt people. A liquid nitrogen tank 12 is arranged in the wall body, and the liquid nitrogen tank 12 is communicated with a liquid guide pipe 13 which is arranged inside the door body 1 in a snake shape. The liquid nitrogen in the liquid nitrogen tank 12 can reduce the temperature of the door body 1 in case of fire, so that the door body 1 is rapidly cooled, the rigidity and the toughness are reduced, and the door body becomes brittle and is beneficial to breaking.
As mentioned above, although the present invention has been shown and described with reference to certain preferred embodiments, it should not be construed as limiting the invention itself. Various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
