Description

Technical Field

[0001] This utility model relates to the field of window opener technology, and in particular to a window opener for casement windows. Background Technology

[0002] In the field of building doors and windows, casement windows have become a common window type in residential and office buildings due to their excellent sealing, ventilation, and space utilization. With the popularization of smart home concepts and the increasing demand for building automation, traditional manual window opening methods are gradually becoming unable to meet users' requirements for convenience and intelligence. As a key device for realizing automated window control, the structural design and operational stability of electric window openers directly affect the user experience. Existing window openers have shortcomings in terms of transmission efficiency, smooth operation, and adaptability, and there is an urgent need for more efficient and stable technical solutions to promote the development of building doors and windows towards intelligence and humanization.

[0003] Existing electric window openers for casement windows mainly include chain-type window openers, which use a built-in motor to drive the extension and retraction of the chain to open and close the window. When the chain extends or retracts, it pushes or pulls the window sash to rotate around the hinge. Screw-type window openers use a nut connected to the window sash. When the motor rotates, the nut moves linearly along the screw to open and close the window sash.

[0004] However, in actual use, existing electric casement window openers have a high failure rate, especially chain-type openers, which are prone to failure due to chain wear and jamming, preventing the window sash from opening and closing properly. This is particularly true in environments with strong winds, sandstorms, or high humidity. After a period of use, these openers frequently malfunction, affecting normal use. Screw-type openers, due to their high installation precision requirements and susceptibility to dirt, are prone to issues such as the screw not turning smoothly and the window sash moving unevenly. They are also more complex to repair. Therefore, a new type of casement window opener is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a window opener for casement windows, which aims to improve the problems of high failure rate of window sashes that cannot be opened and closed normally in the prior art, easy occurrence of unstable window sash movement, and relatively complicated maintenance.

A transmission wheel 4 is fixedly connected to the outer wall of the rotating column 6, and a transmission block 5 is fixedly connected inside the transmission wheel 4. The transmission block 5, through mechanical engagement with the transmission wheel 4, can transmit the rotational force generated by the motor 3 to the next component. A transmission block 5 is fixedly connected to one side of... A connecting column 7 is fixedly connected to a fixed frame 8 on its outer wall. A sliding groove 9 is provided inside the fixed frame 8. A slider 10 is provided inside the fixed frame 8. The slider 10 is slidably connected inside the sliding groove 9. The function of the sliding groove 9 is to provide a movement trajectory for the slider 10, ensuring that the slider 10 slides within a certain range without deviating. A support column 11 is fixedly connected to the top of the slider 10. A connecting rod 12 is rotatably connected to the outer wall of the support column 11. The connecting rod 12, through its connection with the support column 11, realizes the opening and closing of the window 14 under the drive of the motor 3. An opening and closing component is provided at one end of the connecting rod 12.

[0033] The opening and closing assembly includes a connecting block 13 and a window 14. The connecting block 13 is rotatably connected to one end of the connecting rod 12, and one side of the window 14 is fixedly connected to one side of the connecting block 13. The connecting block 13 is a bridge component between the connecting rod 12 and the window 14, ensuring that the window 14 can rotate freely within a certain range. The window 14 is slidably connected inside the wall 1. Through this sliding structure, the window 14 can switch from a closed state to an open state. A sealing assembly is provided on the outer wall of the window 14.

[0035] Working principle: When using this casement window opener, first start the motor 3. Its output end drives the rotating column 6 to rotate, which in turn drives the transmission wheel 4 to rotate. Since the transmission block 5 is fixed inside the transmission wheel 4, the transmission block 5 rotates with the transmission wheel 4, thereby driving the connecting column 7 to move. Inside the fixed frame 8 on the connecting column 7, the slider 10 slides in the slide groove 9. The support column 11 moves with the slider 10, and the support column 11 drives the connecting rod 12 to move. One end of the connecting rod 12 is rotatably connected to the connecting block 13, which is fixed to the window 14. When the connecting rod 12 moves, it drives the window 14 to slide inside the wall 1 through the connecting block 13, realizing the opening and closing action of the window 14.

[0036] During the movement of the window 14, the slide rail 16 and sliding block 17 inside the wall 1 act as guides and supports, ensuring the smooth movement of the window 14. At the same time, the linkage mechanism composed of the fixed rod 18, the first transmission rod 19, the rotating rod 20, the second transmission rod 21, the support rod 22, and the transmission column 23 further assists the movement of the window 14, enabling the window 14 to open and close accurately according to the predetermined trajectory. When the window 14 is closed, the sealing plate 15 on the outer wall of the window 14 fits tightly against the side wall of the wall 1, forming a sealed structure that effectively blocks external dust, rainwater, and noise, ensuring the airtightness and comfort of the indoor environment.
