Technical Field

[0001] The utility model relates to the technical field of center-hung windows, and specifically relates to a center-hung window. Background Art

[0002] As a type of window that can effectively improve indoor ventilation and lighting performance, center-hung windows have been widely used in the construction field. The traditional design of center-hung windows mainly focuses on the opening and closing functions of the windows themselves, and there is limited optimization for their structural stability and installation convenience.

[0003] For example, Chinese Patent CN221256455U discloses a hinge device for a casement window, which includes a frame mounting plate, a sash fixing plate, a first arm, a second arm, and a third arm; one ends of the first arm and the second arm are hinged to the frame mounting plate, and one end of the third arm is hinged to the frame mounting plate and is in sliding fit; the sash fixing plate is respectively hinged to the other ends of the first arm, the second arm, and the third arm; the second arm is arranged between the first arm and the third arm. The first arm and the second arm adopted in the application are of a double-support connection structure, which improves the overall load-bearing capacity and wind pressure resistance of the hinge device. At the same time, the third arm is fixedly connected to the sash fixing plate and is slidably connected to the frame mounting plate, which can solve the problems of friction adjustment and short two-point hole distance in the sash fixing plate, and avoid the defect that the load-bearing force in the traditional technology is concentrated on a certain point or part.

[0004] Most center-hung windows on the market currently use hinges to connect the sash and the window frame to achieve the center-hung opening of the sash. However, this traditional structure has problems such as sash shaking, complex installation, and high technical requirements for installers during use, thereby reducing the practicality. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a center-hung window, which has the advantages of improving the structural stability of the center-hung window, simplifying the installation process, and reducing the technical requirements for installers, etc., and solves the problem that most center-hung windows use hinges to connect the sash and the window frame to achieve the center-hung opening of the sash. However, this traditional structure has problems such as sash shaking, complex installation, and high technical requirements for installers during use, thereby reducing the practicality.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A center-hung window, including a wall body, a window frame, and a sash. Glass is arranged inside the sash, and connection mechanisms are arranged on the left and right sides of the front of the window frame;

[0007] The connecting mechanism includes two fixing grooves, two fixing blocks, two oval positioning grooves, two oval rotating blocks, two connecting shafts and a connecting component. The two fixing grooves are respectively arranged on the left and right sides of the front of the window frame. The two fixing blocks are both fixed to the back walls of the inner cavities of the left and right fixing grooves by threads. The two oval positioning grooves are respectively arranged on the opposite sides of the left and right fixing blocks. The oval rotating blocks are slidably connected to the interiors of the oval positioning grooves.

[0008] By adopting this technical solution, the structural stability of the casement window can be improved through the connecting mechanism, the installation process is simplified, and the technical requirements for installers are reduced.

[0009] Furthermore, a sealing strip is arranged on the inner peripheral wall of the window frame, and a sunshade plate body is arranged on the back of the window sash.

[0010] By adopting this technical solution, the sealing performance when the window is closed is improved by arranging the sealing strip, air leakage is reduced, and the direct sunlight is effectively blocked by arranging the sunshade plate body, thus improving the indoor comfort.

[0011] Furthermore, the opposite sides of the left and right oval rotating blocks are fixedly connected to the opposite sides of the left and right connecting shafts respectively. The left and right connecting shafts are rotatably connected to the left and right sides of the window sash through bearings.

[0012] By adopting this technical solution, the left and right connecting shafts are rotatably connected to the left and right sides of the window sash, and the casement opening of the window sash can be realized.

[0013] Furthermore, the gap between the oval positioning groove and the oval rotating block is in fit.

[0014] By adopting this technical solution, it is convenient to install the window frame and the window sash together through the mutual cooperation between the oval rotating block and the oval positioning groove.

[0015] Furthermore, the left and right connecting shafts are symmetrically distributed on the left and right sides of the longitudinal central axis of the window sash.

[0016] By adopting this technical solution, the casement opening of the window sash can be realized through the left and right connecting shafts.

[0017] Furthermore, the connecting component includes two mounting seats, two guiding grooves, two guiding blocks and four limiting sliding rods. The mounting seats are fixed to the left and right sides of the front of the wall by bolts. The guiding grooves are arranged on the fronts of the mounting seats.

[0018] By adopting this technical solution, the preliminary positioning of the window frame can be completed through the connecting component, and then the window frame is firmly fixed to the wall by fastening screws, simplifying the installation process.

[0019] Further, both of the guiding blocks are arranged on the left and right sides of the window frame. The guiding blocks are slidably connected to the inside of the guiding grooves. All four limiting sliding rods are arranged on the upper and lower sides of the inner back walls of the left and right guiding grooves. The guiding blocks are slidably connected to the outer sides of the limiting sliding rods.

[0020] By adopting this technical solution, the guiding blocks on the left and right sides can be limited by the four limiting sliding rods.

[0021] Further, the guiding blocks linearly move back and forth inside the guiding grooves, and the guiding blocks are in clearance fit with the guiding grooves.

[0022] By adopting this technical solution, the preliminary positioning of the window frame can be quickly completed through the mutual cooperation between the guiding blocks on the left and right sides and the guiding grooves on the left and right sides.

[0023] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0024] 1. For this center-hung window, the connecting shafts that rotate through bearings on the left and right sides of the window sash can achieve the center-hung opening of the window sash. The oval rotating blocks on the left and right sides can be inserted into the oval positioning grooves on the left and right sides, and then the fixing blocks on the left and right sides can be fixed in the fixing grooves on the left and right sides through bolts, so as to achieve the accurate installation of the window sash and the window frame. When installing and fixing the window on the wall, the two mounting seats can be fixed on the left and right sides of the front of the wall through bolts first, and then horizontally installed and fixed according to the size of the window frame. After fixing, just insert the guiding blocks fixed on the left and right sides of the window frame into the front of the guiding grooves on the left and right sides, and the guiding blocks on the left and right sides are located outside the four limiting sliding rods on the left and right sides, then the preliminary positioning of the window frame can be completed. Then, the window frame can be firmly fixed on the wall through fastening screws. Furthermore, through the design of the connecting mechanism, the structural stability of the center-hung window is improved. By adding sealing strips and sunshades, the sealing performance of the window and the indoor comfort are enhanced, the installation process is simplified, and the technical requirements for installers are reduced.
