Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of smoke screen curtain, and particularly relates to a lifting type smoke screen curtain. BACKGROUND

[0002] The smoke screen curtain is a fire safety facility used in buildings, which mainly functions to limit the spread of smoke in the event of fire, and provides a smoke-free environment for personnel evacuation and fire rescue. However, the existing smoke screen curtain has a fixed length and lacks flexibility, and cannot be adjusted. During the use of the building, if the space function changes, the smoke screen curtain with a fixed length may not be able to adapt to the new use requirement, and different lengths of smoke screen curtains need to be purchased again, thereby increasing the replacement cost. CONTENT OF THE UTILITY MODEL

[0003] The utility model aims at solving the above-mentioned problems and provides a lifting type smoke screen curtain.

[0004] The technical scheme of the present application is implemented as follows:

[0005] The present application provides a lifting type smoke screen curtain, which comprises a frame, a fixed plate, a movable plate and a telescopic push rod component. The fixed plate is installed in the frame. The frame comprises a bearing part, a first support part and a second support part. The fixed plate is connected with the bearing part. The first support part and the second support part are respectively located at both ends of the bearing part.

[0006] The fixed plate has a receiving groove. One end of the movable plate is movably arranged in the receiving groove. Through the movement of the one end of the movable plate in the receiving groove, the other end of the movable plate is close to or away from the fixed plate.

[0007] The first support part has a cavity. One end of the cavity extends to the outside of the first support part. The telescopic push rod component is arranged in the cavity. The first support part has an opening which is in communication with the cavity. A connecting part is arranged on the piston end of the telescopic push rod component. One end of the connecting part passes through the opening and is connected with the movable plate.

[0008] The movable plate has a through groove at the bottom. A support rod is arranged in the through groove. A flow guide plate is rotatably arranged on the support rod.

[0009] In an embodiment, a cleaning assembly is further included. The cleaning assembly comprises a placing seat and a cleaning support. The placing seat is arranged on the bearing part. The placing seat has a sliding groove which penetrates the placing seat.

[0010] The cleaning support has a clamping part. When the clamping part is embedded in the sliding groove, the cleaning support is located on one side of the fixed plate, and the cleaning support can move relatively along the length direction of the sliding groove.

[0011] A scraper is arranged on the cleaning support. When the clamping part is installed in the sliding groove, one end of the scraper abuts against the end face of the fixed plate.

[0012] In an embodiment, the second support part is provided with a protrusion part towards one side of the movable plate, and the movable plate is provided with a recess part corresponding to the position of the protrusion part;

[0013] By embedding the protrusion part into the recess part, the movable plate can move along the length direction of the protrusion part.

[0014] In an embodiment, the cleaning assembly further comprises a ball member, the sliding groove is provided with a groove, and the ball member is rotationally arranged in the groove; when the clamping part is installed in the sliding groove, one end of the clamping part abuts against the outer circumferential surface of the ball member.

[0015] The groove is provided with a plurality of grooves and is spaced apart along the length direction of the sliding groove.

[0016] In an embodiment, the bottom of the fixed plate is provided with a limiting plate at both ends, and the movable plate is located between the two limiting plates.

[0017] The movable plate is provided with an end plate at the part located in the accommodating groove, and the end plate is close to or away from the limiting plate with the movement of the movable plate in the accommodating groove.

[0018] In an embodiment, the cleaning assembly is provided with two groups and is located at both sides of the bearing part.

[0019] In an embodiment, the top of the bearing part is provided with a top cover, and the top cover is provided with a mounting hole around.

[0020] The advantages or beneficial effects of the above technical solutions at least include:

[0021] The lifting type smoke blocking vertical wall of the present application is installed on the bearing part in the frame through the fixed plate, and the movable plate is movably arranged in the accommodating groove of the fixed plate, so that the first support part and the second support part are located at both sides of the fixed plate. Since the telescopic push rod part in the first support part is connected with the movable plate through the mounting part, the relative movement of the movable plate can be driven by the telescopic push rod part, so that the movable plate is close to or away from the fixed plate in a lifting manner, thereby adjusting the length of the smoke blocking vertical wall. Since the guide plate is arranged in the through groove of the movable plate and rotates along the support rod, the diffusion of smoke can be further guided and limited by changing the angle of the guide plate. Through the cooperation of the fixed plate, the movable plate and the telescopic push rod part, the overall length of the smoke blocking vertical wall can be adjusted in a lifting manner, thereby solving the problem of fixed length of the traditional smoke blocking vertical wall, which cannot be applied to different spaces and has the problem of limited use.
