Description

Fire door structure

This creation is about a kind of door structure, especially a kind of structure used for fire doors.

Currently, commercially available fire doors must have a certain degree of fire resistance and smoke resistance. However, in actual application of this kind of fire door, it can only be determined by adjusting the shape or separation distance of the door body, frame body, and rotating mechanism to ensure that the door body can reach the preset opening angle at high temperatures. Value (such as 90 degrees, 180 degrees, or 270 degrees). Specifically, when it is expected that the door body will need to be opened by 270 degrees, if the distance between the door body and the frame body is not increased, the shape of the adjacent sides of the door body and the frame body must be designed as a 1/4 arc. This will further increase the difficulty of the manufacturing process and the corresponding cost; on the contrary, if the separation distance between the door and the frame is increased, although the aforementioned problems caused by the adjustment of the design are avoided, there is the expansion of the separation distance to reduce the fire resistance and the fire resistance of the fire door. The ability of dense smoke, in this way, will make the fire door unable to perform its original function.

In order to solve at least one of the above-mentioned problems, some embodiments of this creation propose a door structure, especially a structure for fire doors, which is provided for users to operate intuitively; and can be satisfied at the same time to block gas at high temperatures. advantage. Specifically, it uses a rotating mechanism to guide the door to move within a range of 270 degrees; and through the expansion body arranged in the frame to prevent outdoor air from flowing into the room, the user can go out according to actual application requirements. /Open the door inward to improve the flexibility of the fire door structure.

The fire door structure of the present invention includes at least one door body and a frame body. The at least one door body is configured to be connected to the frame body by a rotating mechanism so as to have a closed position and a first open position and/or a first open position. Move between two open positions; and there is a first passage and a second passage communicating between the frame and the at least one door.

Wherein, the width of the first channel is twice the width of the second channel.

Wherein, the first channel and the second channel are connected to the at least one door at an angle greater than 90 degrees and less than 180 degrees. This will relatively increase the length of the path through which the gas flows, and can delay the time for the gas to flow into the room.

Wherein, the width of the first passage gradually shrinks toward the width of the second passage to the width of the second passage, which will reduce the gas diffusion efficiency, thereby reducing the efficiency of gas flowing into the room.

Wherein, the width of the second channel is gradually reduced to a specific positive value in the opposite direction of the first channel, which will reduce the gas diffusion efficiency, thereby reducing the efficiency of the gas flowing into the room.

Wherein, when the at least one door body is two, the two door systems are fixed to each other in the closed position by a detachable lock member.

Wherein, the frame further includes a recess formed from a surface of the frame contacting the first channel and/or the second channel, and is configured to accommodate at least one expansion body.

Wherein, the at least one expansion body is an anti-smoking rod. In this way, the fire door structure of the present invention can prevent gas from flowing into the room through the first passage and the second passage through the at least one expansion body in response to a high temperature environment.
