A kind of steel wood fire resistant doorsetsTechnical field
The present invention relates to a kind of steel wood fire resistant doorsets, belong to fire resistant doorsets technical field.
Background technique
In order to improve security performance, existing door is generally configured to have fire-proof function, and common mentality of designing is to adoptIt is arranged with the material for having flame retardant property on door body surface or is filled in inside door body；But if fire occurs outside houseWhen, people need to open door escape, be greatly now because causing the damage of people the reason of flue gas, especially in the case of fireIt is to open the door in a flash, external flue gas can be poured in house with very strong air-flow, especially quickly due to losing blocking quicklyIt is easy the damage of human body, and the material time of exactly escape can be made due to intake flue gas excessive at this time to the escape of people at this timeAt very big hidden danger, it is therefore necessary to be further improved.
Summary of the invention
In view of the foregoing drawbacks, and it is an object of the present invention to provide a kind of structure is simple, energy clamshell doors in a flash carry out flue gas the present inventionA kind of good exclusive steel wood fire resistant doorsets.
Thus the technical solution adopted by the present invention is that: the present invention includes door body (1), and door body (1) lower part sets cavity(2), the cavity (2) is latter half of sets gas tank (3), and filled with high pressure gas in the gas tank (3), gas tank (3) front is equipped withOpenable valve (4)；Door body (1) surface be equipped with several ventholes (5), the valve (4) open when and venthole (5)Form an access for flowing high pressure gas.
Thorn stick (6) are equipped in the door body (1), the thorn stick (6) includes vertically disposed thorn stick one (61) and thorn stick two(62)；The thorn stick one (61) is arranged along door body (1) thickness direction, and thorn stick two (62) and thorn stick one (61) are vertically arranged and from institutesIt states gas tank (3) front to penetrate cavity (2), thorn stick two (62) front end forms puncture tip (63) to gas tank (3) direction bending, describedPuncture tip (63) corresponding valve (4) is arranged and can puncture the valve (4)；The thorn stick one (61) is by being arranged in its two sidesElastic piece (7) is connected on door body (1), and the position that thorn stick one (61) is corresponded in the door body (1) is equipped with accommodating thorn stick one (61)And the blind hole (9) run through from door body (1) back plate (8)；Thorn stick one (61) rear end is equipped with can be with thorn stick one (61) connection and bandThe connecting rod (10) that dynamic thorn stick one (61) moves forward and backward.
Thorn stick one (61) rear end offers internal screw thread, and connecting rod (10) front end is equipped with corresponding with the internal screw threadExternal screw thread.
The valve (4) and venthole (5) be not in same level.
The invention has the advantages that 1) gas tank is arranged in the present invention in door body, gas tank internal high-voltage gas passes through gas when normalThe sealing of case stores high pressure gas to gas tank, and when encountering danger, by the opening of gas tank valve, high pressure gas is passed throughDoor body discharges, and is opening the door in a flash in this way, the high pressure gas discharged forms an outside thrust, such people to flue gasFlue gas would not largely be taken in when escape, win valuable time for the escape of personnel；2) present invention passes through connecting rod, thornThe setting of bar, when use, are punctured valve by thorn stick, and structure is simple, using reliable；3) thorn stick is passed through elasticity by the present inventionPiece is connected in door body, when normal in this way puncture tip will not and valve contacts need so that it is guaranteed that high pressure gas can be stored to gas tankWhen high pressure gas discharges, by the connection of connecting rod and thorn stick, thorn stick is driven to move forward and backward by connecting rod, because thorn stick is to pass through bulletProperty body connection, although elastomer can to thorn stick formed constrain, but it is effortless by connecting rod drive move forward and backward, such valveIt is punctured to open, flows out high pressure gas；4) valve and venthole are arranged not in same level the present invention, in this wayValve cannot be punctured from the outside, avoid child because naughty cause puncturing for valve, the present invention uses reliable.

Specific embodiment
The present invention includes door body 1, and 1 lower part of door body sets cavity 2, and the cavity 2 is latter half of to set gas tank 3, the gas tank 3It is interior filled with high pressure gas, 3 front of gas tank is equipped with openable valve 4；1 surface of door body is equipped with several ventholes 5, instituteIt states when valve 4 is opened and venthole 5 forms an access for flowing high pressure gas.
Thorn stick 6 is equipped in the door body 1, the thorn stick 6 includes vertically disposed thorn stick 1 and thorn stick 2 62；The thornBar 1 is arranged along 1 thickness direction of door body, and thorn stick 2 62 and thorn stick 1 are vertically arranged and penetrate cavity from 3 front of gas tank2,2 62 front end of thorn stick forms puncture tip 63 to 3 direction bending of gas tank, and simultaneously energy will be described for the corresponding setting of valve 4 of the puncture tip 63Valve 4 punctures；The thorn stick 1 is connected in door body 1 by the way that the elastic piece 7 of its two sides is arranged in, corresponding in the door body 1The blind hole 9 that the position of thorn stick 1 is equipped with accommodating thorn stick 1 and runs through from 1 back plate 8 of door body；One 61 rear end of thorn stick is equipped withThe connecting rod 10 that can and thorn stick 1 connection and thorn stick 1 is driven to move forward and backward.
One 61 rear end of thorn stick offers internal screw thread, and 10 front end of connecting rod is equipped with outer spiral shell corresponding with the internal screw threadLine.
The valve 4 and venthole 5 be not in same level.
