Description

A chain lifting sliding window

technical field

The invention relates to the field of doors and windows, in particular to a chain lifting sliding window.

Background technique

Existing high-rise windows are mostly casement and push-pull, and casement windows will occupy a certain space no matter they are opened inwardly or outwardly, which brings a lot of inconvenience to users. In order to ensure indoor ventilation and light transmission, sliding windows are relatively large in size and relatively heavy in weight. However, the increased weight of the window sash also brings some other problems, such as heavy weight, inconvenient opening and closing, and difficulty in installation and debugging.

In the prior art, there is inconvenience caused by reducing the weight of the gas spring. For example, "a lift window equipped with gas spring" disclosed in Chinese patent literature, its notification number is CN107905685A; discloses a lift window equipped with gas spring, which belongs to the technical field of lift windows, specifically including window frames and The fixed sash and the movable sash arranged in the window frame alternately, the vertical profile cavity of the window frame is provided with a gas spring, the pneumatic movable rod of the gas spring is connected with the movable sash, the pneumatic fixed rod device and the base of the gas spring are connected with the Window frame connection. In this patent, the impact of self-weight is reduced by gas springs. However, when the length of the gas spring is stretched out and retracted, its power is unequal, and the gas spring itself has unequal power, and the stroke of the gas spring is limited, so the boosting effect is not significant.

In the prior art, there is also a labor-saving structure to solve the self-weight problem. For example, "a new type of labor-saving lifting window" disclosed in the Chinese patent literature, its announcement number is CN111779418A; and a driving mechanism, the window sash that can slide up and down is installed on the window frame, a power chamber is processed on the top of the window frame, and a driving mechanism is installed in the power chamber, and the driving mechanism includes a motor, an active screw rod, a passive wire A booster mechanism for decomposing the sash is installed in the power chamber below the motor below the rod, synchronous wheel and synchronous belt. In this patent, the problem of self-weight of the window sash is solved through the screw rods on both sides, the motor on the top and the gas spring booster mechanism; however, the top motor still needs a lot of power to drive, and the load is large, which affects the stability of the motor operation, and generally the power is large. The volume of the motor is also large, which is not conducive to the overall installation; and the use of gas springs still has the above-mentioned problems.

Since the above-mentioned two window sash are arranged in the same plane, and the above-mentioned sprockets and the above-mentioned window sash are all arranged in the same plane, the force on both ends of the above-mentioned chain is consistent, and the self-weight problem is solved. ; The power provided by the driving motor only needs to overcome the overall static friction, so only a small power needs to be provided, so the volume can be effectively controlled and the overall installation is convenient; and the driving motor is arranged on the top column, and the position is arranged reasonably.

Further, the two ends of the window sash are also provided with limiting components. The limit assembly can ensure the stability of the above-mentioned window sash during movement without swinging back and forth, thereby improving the service life and ensuring the overall stable operation.

Further, the limit assembly includes a slide rail arranged on the side column and a slide block fixedly connected with the window clamp and adapted to the slide rail. Through the cooperation of the above-mentioned slide rail and the above-mentioned slider, the stability of the above-mentioned window sash is guaranteed, and the structure is simple.

Further, the first sprocket and the second sprocket are flush with one end close to the window sash. The above setting can ensure that the force on both ends of the above chain is in the vertical direction, which increases the service life and improves the running stability of the window sash.

Further, the drive motor is a biaxial drive motor; there are two reducers. The structure is simple, and the driving structure symmetrically arranged on both sides can ensure that the force on both sides of the window sash is even, and the window sash runs smoothly during operation, and at the same time can improve the service life of the two chains.

Further, the window sash is hollow tempered glass. High strength, good thermal stability, can ensure the safety of use, and the sound insulation effect is remarkable.

Compared with the prior art, the advantages of the present invention are: through the combined use of sprockets, the problem of the self-weight of the window sash is solved, and the window sash can be opened and closed only by overcoming the friction of the system, which improves the service life of the motor and reduces the The size of the motor makes the structure compact and convenient for installation and debugging.
