Technical Field
[0001] The utility model belongs to the technical field of door and window sealing, in particular to a fire-resistant reinforced sealing structure for building doors and windows. Background Technique
[0002] Doors and windows are divided into enclosure components or partition components according to their different positions, and have different design requirements. They should respectively have functions such as heat preservation, heat insulation, sound insulation, waterproofing, and fire prevention. Building doors and windows are an indispensable part of a building. In addition to functions such as lighting, ventilation, and traffic, they also have the function of heat insulation. During the installation process of doors and windows, a sealing structure is often used to seal the gaps of the doors and windows to prevent external dust or rainwater from entering the room through the gaps of the doors and windows when they are closed, and at the same time reduce the loss of indoor hot air or cold air.
[0003] At present, most of the existing sealing structures are sealing rubber strips. After long-term use, the sealing rubber strips are prone to aging and breaking, resulting in water seepage and air leakage, affecting the sealing effect of the doors and windows. At the same time, during the long-term use process, the repeated opening and closing of the doors and windows will cause wear to the sealing rubber strips, making the sealing rubber strips unable to abut against the window sashes of the doors and windows, resulting in gaps on the doors and windows and unable to achieve the sealing effect, with a short service life.
[0004] In view of the above problems, we propose a fire-resistant reinforced sealing structure for building doors and windows. Content of the Utility Model

Second sealing grooves are opened on one side surface of both sliding windows. Second sealing components are arranged on both the left and right sides of the chute and are matched with the second sealing grooves.
[0007] The first sealing component includes a first cavity, a movable plate, a first sealing block, a first spring, and a vertical rod. The two first cavities are respectively opened on the upper and lower sides inside the frame. A strip-shaped groove is opened on one side of the inner wall of the first cavity close to the chute, and the strip-shaped groove is communicated with the chute. The movable plate is movably arranged inside the first cavity. The first sealing block is fixed on the side of the movable plate close to the sliding window, and the first sealing block is matched with the strip-shaped groove and the first sealing groove.
[0008] A plurality of the first springs are all fixed on the side of the movable plate away from the first sealing block, the other ends of the first springs are fixedly connected with the inner wall of the first cavity, a plurality of the vertical rods are all fixed inside the first cavity, and the vertical rods penetrate through the movable plate, the movable plate is in sliding fit with the vertical rods, and the first springs are sleeved outside the vertical rods.
[0009] The second sealing assembly includes a second cavity, a pressing plate, a second sealing block, a screw rod, a pressing rod, a cross bar, a second spring and a knob. The two second cavities are oppositely formed on the left and right sides inside the frame. The pressing plate is movably arranged inside the second cavity. A through groove penetrates through one side of the inner wall of the second cavity close to the sliding groove. The second sealing block is fixed on the side of the pressing plate close to the sliding window. The second sealing block is matched with the through groove and the second sealing groove. The screw rod is in threaded fit with the frame. The inner end of the screw rod extends into the second cavity and is fixedly connected with the pressing rod. The pressing rod is matched with the pressing plate and the inner wall of the second cavity. A third sealing groove is formed on the side of the movable plate and the first sealing block close to the through groove. The second sealing block is matched with the third sealing groove.
[0010] The two cross bars are oppositely fixed on the upper and lower sides inside the second cavity, and the cross bars penetrate through the pressing plate. The pressing plate is in sliding fit with the cross bars. The second spring is connected to the side of the pressing plate away from the second sealing block, and the other end of the second spring is fixedly connected with the inner wall of the second cavity. The second spring is sleeved outside the cross bar.
[0011] The knob is fixedly connected to the outer end of the screw rod.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] Through the elastic action of the first spring, the present utility model facilitates pressing the movable plate towards the direction close to the sliding window, thereby driving the first sealing block to pass through the strip-shaped groove and be clamped into the first sealing groove, effectively sealing the upper and lower sides of the sliding window. The vertical rod effectively limits the movable plate, ensuring the stability of the movable plate during the up and down movement process.
[0014] During the process of repeatedly sliding and opening / closing the sliding window, the first sealing block is worn. Under the elastic action of the first spring and combined with the movable plate, the first sealing block can be continuously pressed towards the direction close to the sliding window, so that the first sealing block is always clamped in the first sealing groove, solving the drawbacks that in the prior art, during the long-term use of the sealing structure used for doors and windows, the repeated opening and closing of the doors and windows will wear the sealing rubber strip, making the sealing rubber strip unable to abut against the window sash of the doors and windows, resulting in gaps on the doors and windows and being unable to achieve the sealing effect, and having a short service life.
[0015] Meanwhile, through the threaded fit between the screw rod and the frame, it is convenient to adjust the screw rod to screw into the second cavity. During this process, as the screw rod screws in, it drives the extrusion rod to rotate to an inclined state and get stuck between the extrusion plate and the inner wall of the second cavity, thereby squeezing the extrusion plate towards the direction close to the sliding window until the second sealing block is driven to pass through the through groove and snap into the corresponding second sealing groove and third sealing groove, achieving the purpose of sealing both sides of the sliding window and effectively enhancing the sealing effect of the doors and windows.
