Problems solved by technology

[0004] In theory, the fire door needs to be kept closed, but in actual use, due to various human factors, people often open the fire door but forget to close it, resulting in the fire door being open. When a fire breaks out, due to fire The door is open, causing the smoke to flow through the fire door to the escape channel, thus affecting people's escape, and the safety performance is low

Embodiment 1

[0039] see Figure 1-6 , a kind of pneumatic sure-closing smoke-resistance type safety fire door, including a door panel body 101 hinged with the wall and a cylinder receiving groove 104 opened on the inner side of the wall body, an arc-shaped guide cylinder 102 is fixedly installed in the receiving cylinder groove 104, An arc-shaped door closing rod 103 is slidably connected in the guide cylinder 102. One end of the arc-shaped door closing rod 103 penetrates the outer wall of the arc-shaped guide cylinder 102 and extends to be fixedly connected with the door panel body 101. The arc-shaped guide cylinder 102, the arc-shaped closing rod 103 The door levers 103 are all arranged in an arc shape matching the opening trajectory of the door panel body 101, so that the door panel body 101 and the arc-shaped door closing lever 103 can be linked without hindering the opening and closing of the door panel body 101. A drive-close adjustment groove 105 is opened on one side of the cylinde...

Abstract

The invention discloses a pneumatic type sure-closing smoke-resisting safety fire door, which belongs to the technical field of fire doors. When a fire occurs, the thorn ball steel needle can spontaneously pierce the storage balloon, so that the pneumatic solution flows out and the pneumatic powder reacts to generate a large amount of carbon dioxide. , so as to close the fire door in the open state to ensure that the fire door is closed when a fire occurs, thereby preventing the smoke from rushing through the fire door to the escape channel, greatly improving the safety performance, and through the setting of the vent door assembly, the escape personnel On both sides of the fire door, the first valve and the second valve can be used to connect the vent main pipe, so that carbon dioxide can be ejected, and the fire door can be opened smoothly. It can prevent the spread of the fire and gain more time for people to escape.

Description

technical field [0001] The invention relates to the technical field of fire doors, and more particularly, to a pneumatic type sure-closing smoke-proof safety fire door. Background technique [0002] Fireproof materials refer to various materials that play an absolute role in modern fire prevention and are mostly used in construction. Commonly used fireproof materials include fireproof boards, fireproof doors, fireproof glass, fireproof paint fireproof bags, etc. Among them, the fire door refers to the door that can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. [0003] In addition to the function of ordinary doors, fire doors can also prevent the spread of fire within a certain period of time and ensure the evacuation of people. When a fire occurs, not only the high temperature of the fire, but also the smoke emitted by the burning of objects threatens people's lives. According to statistics, more than 80...
