Description

Technical Field

[0001] The utility model belongs to the technical field of curtains, and in particular relates to an automatic fireproof and smoke-blocking curtain. Background Art

[0002] In recent years, fire accidents in civil buildings have occurred repeatedly. When a fire occurs, high-temperature smoke enters the room through the building's exterior windows, causing large-scale fire accidents.

[0003] According to the "General Code for Building Fire Protection", only a few buildings, such as high-rise residential buildings and Class A and Class B factory buildings, should use fireproof windows. Fireproof windows have good smoke and fireproof properties. At present, for ordinary residential buildings, especially low-rise windows of informal buildings such as rental houses, small factory buildings and shops along the street, when there is a fire due to outdoor electric vehicle charging, the white glass or hollow windows will break after being heated for 2 minutes, and a large amount of high-temperature smoke will be poured into the room. In order to improve the fireproof performance, the traditional method is to replace ordinary windows with fireproof windows, which has the following defects: the structural stability of the newly installed fireproof windows is defective, because they are installed after removal, and the fit with the wall is not enough, which is prone to accidents; the cost is high and the economy is not enough.

[0004] There is also a fireproof curtain to achieve a certain fireproof effect. The existing Chinese patent CN209863247U discloses an automatic fireproof curtain, and specifically discloses that the automatic fireproof curtain includes a curtain cloth body and a curtain box, the curtain box includes a middle plate and two side clamps, and the two side clamps can clamp the upper end of the curtain cloth body through mutually meshing teeth. When a fire occurs, the smoke sensor on the curtain box detects that the smoke exceeds a certain threshold and sends a signal to the controller. The controller sends a rotation opening signal to the motor, and the motor controls the rotation of the rotating shaft so that the mutually meshing teeth of the clamps are no longer meshed, so that the curtain cloth body cannot be clamped, and the curtain cloth body automatically falls off. The indoor personnel can pick up the curtain cloth body and place the curtain cloth body on the fire to cover it. Based on its fireproof and flame-retardant properties, the fire is weakened, and the rope is tightened to limit the fire to a small area, thereby improving the fire extinguishing effect. It needs to cooperate with the electric control sensor and the motor to realize the falling control of the curtain cloth, and the use cost is relatively high. Utility Model Content

[0005] The purpose of the utility model is to solve at least one problem of the prior art and to provide an automatic fireproof and smokeproof curtain.

[0006] To achieve the above-mentioned purpose, the utility model proposes an automatic fireproof and smoke-proof curtain, comprising a curtain box, a linkage control device, and a fireproof curtain. The curtain box comprises a box body and a rotating shaft rotatably installed on the box body. The box body is provided with an opening. The box body is installed on a building wall located on the upper edge of a window frame with the opening facing downward. The linkage control device comprises a steel wire rope and a constant temperature trigger installed on the steel wire rope. The steel wire rope is installed around the window frame. The fireproof curtain is wound on the outside of the rotating shaft. A counterweight is provided at one end of the fireproof curtain close to the opening of the box body. The steel wire rope passes through the box body and is connected to the counterweight. The constant temperature trigger breaks after reaching a specified temperature, causing the steel wire rope to automatically disconnect and loosen, thereby causing the fireproof curtain to automatically fall.

[0007] Preferably, the constant temperature trigger is a constant temperature molten metal sheet or a constant temperature glass tube.

[0008] Preferably, the number of the constant temperature triggers is one or more, and the positioning trigger is located on the steel wire rope at the lower edge or side edge of the window frame.

[0009] Preferably, the linkage control device further comprises a wire rope retaining member, which is located on the building wall near the lower corner of the window frame and is used to control the tension or looseness of the wire rope.

[0010] Preferably, the wire rope retaining member is a quick clamp tensioner.

[0011] Preferably, the box body is provided with a supporting angle plate, and the supporting angle plate is used to install the box body on the wall of the building.

[0012] Preferably, bearing seats are installed on the inner walls at both ends of the box body, and the two ends of the rotating shaft are inserted into the bearing seats, and bearings are installed between the rotating shaft and the bearing seats.

[0013] Preferably, two baffles are installed on the outer side of the rotating shaft, and the fireproof curtain is wound around the outer area of ​​the rotating shaft between the two baffles.

[0014] Preferably, both ends of the counterweight are provided with wire rope connection holes.

[0015] Preferably, the counterweight is L-shaped, rectangular or cylindrical, and is a metal component.

[0016] The beneficial effects of the utility model are as follows: the utility model can control the tightness of the steel wire rope by whether the constant temperature trigger reaches the specified temperature without using electronic control sensors and motors, and control the suspension, curling or automatic extension and falling state of the fireproof curtain by the linkage action of the steel wire rope and the counterweight. When the constant temperature trigger breaks after reaching the specified temperature, the steel wire rope automatically disconnects and loosens, and the fireproof curtain automatically falls, thereby achieving the corresponding fire and smoke blocking effect.
