Description

Technical Field

[0001] The utility model relates to the technical field of windows, in particular to a lifting structure for a casement bottom-hung window. Background Art

[0002] In housing construction, casement bottom-hung windows are becoming more and more common. This type of window can be opened and hung. The casement position can take into account large air volume ventilation when the user is indoors, and the hanging position can take into account both ventilation and preventing rain from drifting into the room through the window when it is windy and rainy when the user is away from the room. Therefore, the casement bottom-hung window type can be favored by more and more users. However, due to the weight of the window sash and the long-term opening and closing friction, when the temperature difference between indoor and outdoor is large, the moisture on the window is easy to condense into water droplets, resulting in a short window life, unbalanced and unstable window sash, air leakage and loose safety hazards. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a lifting structure for a casement bottom-hung window, which solves the problem that after the existing doors and windows have been used for a long time, the window sash will move downward or tilt due to the loosening of the hinges, which may easily cause the bottom of the window sash to rub against the window frame when the window sash is closed, generating noise. If the window sash rubs against the window frame and cannot be completely closed, the sealing performance of the window will be reduced, resulting in the loss of cold air or hot air and the penetration of water. When the temperature difference between indoor and outdoor is large, the moisture on the window will easily condense into water droplets, resulting in poor practicality.

[0004] To achieve the above purpose, the utility model is implemented through the following technical solutions: a lifting structure for a casement bottom-hung window, comprising a lifting fixing seat fixedly connected to the window frame and a lifting block fixedly installed on the outer frame of the window sash, an L-shaped fixing strip fixedly installed on the surface of the lifting fixing seat, threaded fixing holes are evenly arranged on the surfaces of the L-shaped fixing strip and the lifting fixing seat, a lifting fixing piece is fixedly installed on the top of the L-shaped fixing strip, a first positioning groove is arranged on the side of the lifting fixing piece, bolt fixing holes are evenly arranged on the surface of the lifting fixing piece, a second positioning groove is arranged on the side of the lifting fixing seat, and screw holes are evenly arranged on the surface of the lifting fixing seat. There is a threaded mounting hole, the surface of the lifting fixing seat is fittedly connected with an adjustable positioning slider, the surface of the adjustable positioning slider is provided with an elliptical hole, the adjustable positioning slider is fixedly connected to the threaded mounting hole by a bolt, the surface of the lifting fixing seat close to the lifting fixing is fixedly connected with a limiting block, the surface of the lifting block is fixedly connected with a limiting plate, the surface of the lifting block is provided with a mounting groove, the interior of the mounting groove is fixedly connected with a fixed shaft, the interior of the mounting groove is clamped with a spring bar, the outer surface of the fixed shaft is rotatably connected with a lifting arm, the surface of the lifting arm close to the spring bar is fixedly connected with a protrusion, and the surface of the lifting arm is provided with a clamping groove.

[0005] Preferably, the lifting fixture is fixedly connected to the window frame by screws, and the limiting plate is fixedly connected to the top of the window sash outer frame by screws. By arranging 90-degree clips in both horizontal and vertical directions on the fixed base and fixing them with screws, the force is better applied and the use is safer.

[0006] Preferably, the shape of the limit block matches the shape of the slot, and the bottom end of the inner wall of the slot is arc-shaped, so that the lifting height of the window sash can be flexibly adjusted, thereby increasing the scope of application.

[0007] Preferably, the lifting arm is rotatably connected to the surface of the lifting block with the fixed axis as the center. When the window is opened and hung down, there is an inverted hook to balance the window left and right, which is safer when in use.

[0008] Preferably, the end of the lifting arm away from the slot is arc-shaped, and the upper surface of the adjustable positioning slider is arc-shaped, which can make the window more balanced up and down, left and right, more beautiful, and better sealed.

[0009] Preferably, the spring bar is "U"-shaped. Beneficial Effects

[0010] The utility model provides a lifting structure for a casement bottom-hung window. Compared with the prior art, it has the following beneficial effects:

[0011] 1. The lifting structure of the casement bottom-hung window is provided with a lifting fixed seat and a lifting block. When the window is closed, the window sash drives the lifting arm toward the lifting fixed seat through the lifting block. When the bottom end of the lifting arm abuts against the surface of the adjustable positioning slider, the lifting arm rotates counterclockwise. When the window sash is closed, the outer surface of the limit block abuts against the inside of the card slot and drives the window sash to move upward as a whole. When the temperature difference between indoor and outdoor is large, the moisture on the window is easy to condense into water droplets. Through a slight upward movement, the sealing state between the window and the window frame can be changed, reducing the chance of moisture entering the room, thereby reducing the possibility of condensation on the window.

[0012] 2. The lifting structure of the casement bottom-hung window is used when the window sash of the bottom-hung outward-opening window is opened. Through the elasticity of the spring bar, the end of the lifting arm can be pressed against the surface of the adjustable positioning slider, which can support the lifting block and the opening of the window sash, thereby enhancing the balance stability.

[0024] When closing the window, the window sash drives the lifting arm 11 toward the lifting fixed seat 1 through the lifting block 6. When the bottom end of the lifting arm 11 abuts against the surface of the adjustable positioning slider 4, the lifting arm 11 rotates counterclockwise. When the window sash is closed, the outer surface of the limit block 5 abuts against the inside of the card slot 13 and drives the window sash to move upward as a whole. When the temperature difference between indoor and outdoor is large, the moisture on the window is easy to condense into water droplets. Through a slight upward movement, the sealing state between the window and the window frame can be changed, reducing the chance of moisture entering the room, thereby reducing the possibility of condensation on the window. When this structure is used in a bottom-hung outward-opening window, after opening the window sash, the lifting arm 11 rotates clockwise through the elasticity of the spring bar 10, so that the end of the lifting arm 11 can abut against the surface of the adjustable positioning slider 4, which can support the lifting block 6 and the opening of the window sash, thereby enhancing the balance stability.
