Balanced locking structure of casement hopper window

Abstract

The utility model discloses a balance locking structure of a side-hung hopper window, and relates to the technical field of windows. The balance locking structure of the side-hung hopper window comprises a fixing clamping piece fixedly installed on a window frame, and a fixing base is fixedly installed on the surface of the fixing clamping piece through a bolt. By arranging the lifting arm and the lifting block, when the window is closed, the window sash profile can drive the lifting block to move, at the moment, the eccentric nail can abut against the inner wall of the sliding groove to drive the lifting arm to rotate anticlockwise, and meanwhile the lifting arm drives the eccentric nail to move upwards; a sealing space is formed between the window sash and the window frame by slightly lifting the window sash through the lifting block, and a pressure difference can be created, so that internal air is extruded between the window frame and the sealing strip to form a tighter seal, and when the window is opened, the angle of the window sash can be supported through clamping of the eccentric nail and the sliding groove, so that the sealing effect is improved. The window sash is in a state of being stably opened in a left-right balance mode, and the bearing adaptability of the hinge is shared.

Description

Technical Field

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

[0002] At present, casement bottom-hung windows are widely used in buildings. They can be opened horizontally, so that the window sash has a wide opening range and fast ventilation to the outside world, and can also be hung downward, so that in bad weather, the window sash can be slightly opened to achieve good ventilation conditions and prevent falling from high altitudes; therefore, they are popular among users. Traditional casement windows or bottom-hung windows are fully opened or closed in the vertical or horizontal direction by rotating the handle or pull rod on the window sash. When the window is used for a long time, the hinges become loose, and friction between the surface of the window sash and the window frame is likely to occur, which can easily cause damage to the window and the sealing cannot be guaranteed. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a balanced locking structure for a casement bottom-hung window, which solves the problem that traditional casement windows or bottom-hung windows are fully opened or closed in the vertical or horizontal direction by rotating a handle or a pull rod on the window sash. When the window is used for a long time, the hinge becomes loose, friction is likely to occur between the surface of the window sash and the window frame, which can easily cause damage to the window and the sealing cannot be guaranteed.

[0004] To achieve the above purpose, the utility model is implemented by the following technical solutions: a balanced locking structure of a casement bottom-hung window, comprising a fixing clip fixedly installed on a window frame and a lifting block fixedly connected to a sash frame, a fixing seat is fixedly installed on the surface of the fixing clip by bolts, a slot is provided on the surface of the fixing seat away from the fixing clip, a mounting column is fixedly connected inside the slot, a spring bar is movably installed inside the slot, a lifting arm is rotatably connected to the outer surface of the mounting column, a convex block is fixedly connected to the surface of the lifting arm close to the fixing seat, a sliding groove is provided on the surface of the lifting arm close to the first fixing plate, a second fixing plate is fixedly connected to the top of the lifting block, an eccentric nail is fixedly connected to the outer surface of the lifting block, an L-shaped fixing strip is fixedly installed on the surface of the fixing clip, threaded fixing holes are equidistantly provided on the surfaces of the L-shaped fixing strip and the fixing clip, a first fixing plate is fixedly installed on the top of the L-shaped fixing strip, a first positioning groove is provided on the side of the first fixing plate, bolt fixing holes are equidistantly provided on the surface of the first fixing plate, and a second positioning groove is provided on the side of the fixing clip.

[0005] Preferably, the spring bar is "U"-shaped, and the surface of the protrusion abuts against the surface of the spring bar.

[0006] Preferably, the surface of the eccentric nail abuts against the inner wall of the slide groove, and the slide groove is arc-shaped.

[0007] Preferably, the surface of the lifting arm is rotatably connected to the surface of the fixing seat.

[0008] Preferably, under normal conditions, the lifting arm rotates clockwise due to the elasticity of the spring bar.

[0009] Preferably, the first fixing plate is fixedly connected to the window frame by screws, and the second fixing plate is fixedly connected to the sash frame by screws. Beneficial Effects

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

[0011] 1. The balanced locking structure of the casement bottom-hung window is provided with a lifting arm and a lifting block, etc. When the window is closed, the window sash profile will drive the lifting block to move. At this time, the eccentric nail will abut against the inner wall of the slide groove and drive the lifting arm to rotate counterclockwise. Due to the shape of the slide groove, the eccentric nail abuts against the surface of the slide groove while the lifting arm drives the eccentric nail to move upward, and can drive the window sash to slightly lift up through the lifting block. When the window sash is closed, a sealed space is formed between it and the window frame. By slightly lifting the window sash, a pressure difference can be created, so that the internal air is squeezed between the window frame and the sealing strip to form a tighter seal, thereby improving the sealing performance. When the window is opened, the angle of the window sash can be supported by the clamping of the eccentric nail and the slide groove, so that the window sash can be in a stably opened state, thereby enhancing stability.

[0012] 2. The balanced locking structure of the casement bottom-hung window allows the edge of the window sash to be in closer contact with the window frame sealing strip by lifting the window sash, which can reduce the gap between the window sash and the sealing strip, improve the sealing performance, and prevent the leakage of air and other substances.
