The lifting device includes two first guide rods and a lifter arranged symmetrically, a guide sleeve is set on the first guide rod, the guide sleeve is installed on the bracket, and one end of the lifter is hinged on the bottom of the window frame The other end is hinged to the bottom surface of the bracket.

The elevator adopts a scissors linkage mechanism, which is composed of several scissor arms.

The driving device includes a motor, a reducer, a bearing seat, a screw and a nut corresponding to the screw, the input end of the reducer is connected to the output shaft of the motor, and the output end of the reducer is connected to one end of the screw rod. The screw nut corresponding to the screw mandrel is sleeved on the screw mandrel and hinged at the bottom of the lifting device, and the screw mandrel is supported by the bearing seat.

The outside of the window frame is also provided with a symmetrically arranged second guide rod, and a counterweight is provided on the second guide rod, and the counterweight is connected to the bracket by passing around a guide wheel installed on the window frame through a wire rope.

The window frame and the glass are provided with sealing strips.

The beneficial effects of the utility model are:

(1) The utility model can make the lifting device rise and fall automatically under the driving of the driving device, so as to realize the opening and closing of the window;

(2) The utility model adopts a scissor-type lifting device, which can realize a higher length of lifting in a shorter moving space;

(3) The utility model increases the counterweight, which can reduce the power of the driving motor.

detailed description:

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

As shown in Figure 1, a lifting window includes a window frame 2, a glass 1, a bracket 3, a lifting device 4 and a driving device 7, the glass 1 is embedded and slidably installed on the window frame 2, and can be The frame 2 moves up and down, the bottom of the glass 1 is supported by a bracket 3 , and a lifting device 4 is arranged below the bracket 3 , and the lifting device 4 is driven by a driving device 7 . The lifting device 4 is driven by the driving device 7 and can push the bracket 3 to move up and down. The lifting device 4 includes two first guide rods 5 and an elevator that are symmetrically arranged, and a guide sleeve 10 is set on the first guide rod 5, and the guide sleeve 10 is installed on the bracket 3, and the guide sleeve 10 and the The contact of the first guide rod 5 can reduce the friction between the bracket 3 and the guide rod, make the bracket 3 rise and fall more smoothly, and at the same time reduce the wear and tear on the bracket 3 and prolong the service life. One end of the elevator is hinged on the bottom of the window frame 2 , and the other end is hinged on the bottom of the bracket 3 . The elevator adopts a scissors linkage mechanism, which is composed of several scissor arms. One of the pair of scissor arms hinged with the bottom edge of the window frame 2 is a fixed hinge, and the other is a movable hinge. The movable hinged scissor arm is provided with rollers. One of the yokes is a fixed hinge, and the other is a movable hinge. The driving device 7 includes a motor 71, a speed reducer 72, a bearing seat 73, a screw 74 and a screw nut 75 corresponding to the screw 74. The input end of the motor 72 is connected to the output shaft of the motor 71, the output end of the reducer 72 is connected to one end of the screw rod, and the screw nut 75 corresponding to the screw rod is set on the screw rod and hinged at the bottom of the lifting device 4, specifically Screw nut 75 is hinged on the scissors arm that is provided with roller, and described screw mandrel is supported by bearing seat 73. The outer side of the window frame 2 is also provided with a symmetrically arranged second guide rod 8, the second guide rod 8 is provided with a counterweight 6, and the counterweight 6 bypasses the guide wheel installed on the window frame 2 through a steel wire rope 9 11 is connected with the bracket 3, increasing the counterweight 6 can greatly reduce the power of the motor 71 on the driving device 7. A sealing strip is provided at the position between the window frame 2 and the glass 1 .

The specific working process of this kind of lift window is as follows: Assuming that the motor 71 rotates forward and the lift rises, when the set window opening time is reached, the motor 71 reverses to drive the screw to rotate, and the screw rotation drives the screw nut 75 fixed on the lift move, the movable scissor arm of the scissor lift moves outward, the distance between the two scissor arms increases, the elevator descends, the supporting plate supporting the glass 1 descends, and the counterweight 6 rises under the traction of the steel wire rope 9, The window is opened; when the set window closing time is reached, the motor 71 rotates forward, the screw rod drives the screw nut 75 to move, the movable scissor arm of the scissor lift moves inward, and the distance between the two scissor arms decreases , move closer to the middle, the elevator rises, promotes the supporting plate supporting the glass 1 to rise, and the window is closed.

Although the specific implementation of the utility model has been described above in conjunction with the accompanying drawings, it does not limit the protection scope of the utility model. Those skilled in the art should understand that on the basis of the technical solution of the utility model, those skilled in the art do not need to Various modifications or deformations that can be made with creative efforts are still within the protection scope of the present utility model.
