Description

Technical Field

[0001] This utility model relates to ventilation windows, and more particularly to ventilation window opening and closing devices. Background Technology

[0002] Ventilation windows are a common structure in buildings such as factories, warehouses, and parking garages. They are typically used to increase indoor and outdoor air circulation, expel stale air, and introduce fresh air.

[0003] Ventilation window opening and closing devices are used to control the opening and closing of ventilation windows. Push-rod window openers or chain window openers are typically selected. Push-rod window openers are more widely used due to their higher operational stability. When using a push-rod window opener, the model should be selected according to requirements, and then the installation position should be designed to control the distance between the push-rod window opener and the window sash. The push-rod window opener includes a driving component and a driven component. By controlling the stroke of the push-rod window opener, the opening amount of the window sash is controlled. To reduce output power, the push-rod window opener is connected to the swing end of the window sash, ensuring driving stability and providing stable support for the window sash after opening. Since the stroke of the push-rod window opener is relatively large, a longer push-rod window opener is required. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a ventilation window opening and closing device that can expand the window sash opening stroke when the length of the push rod window opener is relatively short.

[0005] This utility model is achieved through the following technical solution: a ventilation window opening and closing device, including an opening and closing drive device disposed between the window sash and the window frame, the opening and closing drive device including a telescopic component, the telescopic component including a driving component and a driven component, the driving component being hinged to the window frame via a telescopic arm, configured such that, in the open state, the telescopic arm is inclined upward and retracted, and in the closed state, the telescopic arm is inclined downward and extended.

[0006] Furthermore, the telescopic arm includes an outer arm connected to the window frame and an inner arm connected to the drive component. The end of the outer arm is provided with a fixed guide sleeve that cooperates with the inner arm, and the end of the inner arm is provided with a sliding guide sleeve that cooperates with the inner wall of the outer arm.

[0007] Furthermore, the drive component is connected to the telescopic arm via a position adjustment device, which allows the distance between the drive component and the window sash to be adjusted.

[0008] Furthermore, the position adjustment device includes a connecting seat that mates with the outer wall of the driving component, and the connecting seat has an elongated connecting groove along the direction of movement of the driven component. The driving component is connected to a connecting post that mates with the connecting groove.

[0009] Furthermore, the drive component is also connected to a clamp, which is connected to a connecting column.

[0010] Furthermore, an anti-slip layer is provided between the clamp and the drive component.

[0011] The beneficial effects of this utility model are as follows: the drive component is hinged to the window frame via a telescopic arm. In the open state, the telescopic arm is angled upward and retracted, causing the drive component to move upward, thereby increasing the opening stroke of the window sash. In the closed state, the telescopic arm is angled downward and extended, causing the drive component to descend, thereby increasing the storage space of the telescopic component. By combining the rising and falling of the drive component itself, the effect of expanding the opening stroke of the window sash is achieved even with a relatively short telescopic component.

[0019] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0021] Example 1

[0022] like Figure 1-6 As shown, a ventilation window opening and closing device includes an opening and closing drive device installed between the window sash 2 and the window frame 1. The opening and closing drive device includes a telescopic component, which is an electric push rod, providing stable operation and convenient control. The electric push rod itself includes a driving component 3 and a driven component 4. The driving component 3 is hinged to the window frame 1 via a telescopic arm 6. For ease of installation, a connecting shaft is installed on the window frame 1, and a hinge seat 5 is installed on the telescopic arm 6. The hinge seat 5 is hinged to the connecting shaft and can rotate around the connecting shaft. The connecting shaft is perpendicular to the electric push rod, and the electric push rod is perpendicular to the telescopic arm 6. The design of the position of the connecting shaft and the window sash 2, the selection of the length specification of the electric push rod, and the design of the length value of the telescopic arm 6 are such that, in the open state, the telescopic arm 6 is angled upwards and retracted, causing the driving component 3 to move upwards, thereby increasing the opening stroke of the window sash 2. In the closed state, the telescopic arm 6 is angled upwards... The telescopic arm 6 extends, causing the drive component 3 to descend, thereby increasing the storage space for the telescopic component. Combined with the rising and falling of the drive component 3 itself, this achieves the effect of expanding the opening stroke of the window sash 2 even with a relatively short electric push rod. During the opening process, the electric push rod moves, pushing the window sash 2 upward. At the same time, the electric push rod and the telescopic arm 6 rotate around the connecting shaft. When the telescopic arm 6 is tilted upward, it is subjected to pressure and contracts. Since the window sash 2 has a closing action when the telescopic arm 6 contracts, the length of the outer arm 601 is controlled to be 4-5 times the length of the inner arm 602, which can control the closing stroke of the window sash 2. During the closing process, the electric push rod moves, pulling the window sash 2 downward. At the same time, the electric push rod and the telescopic arm 6 rotate around the connecting shaft. When the telescopic arm 6 is tilted downward, it is subjected to pressure and extends. No additional telescopic drive structure is needed, and the overall structure is simple.

[0023] In this embodiment, the telescopic arm 6 includes an outer arm 601 connected to the window frame 1 and an inner arm 602 connected to the drive component 3. The end of the outer arm 601 is bolted with a fixed guide sleeve 603 that cooperates with the inner arm 602. The end of the inner arm 602 is threadedly connected with a sliding guide sleeve 604 that cooperates with the inner wall of the outer arm 601. Through the sliding guide sleeve 604 and the fixed guide sleeve 603, the inner arm 602 can move stably, while the sliding guide sleeve 604 can prevent the inner arm 602 from disengaging from the outer arm 601.

[0024] The drive component 3 is connected to the telescopic arm 6 via a position adjustment device. The position adjustment device can adjust the distance between the drive component 3 and the window sash 2. Specifically, the position adjustment device includes a connecting seat 7 that mates with the outer wall of the drive component 3. The connecting seat 7 is an arc-shaped plate that connects to the inner arm 602 at the middle position of the arc-shaped plate. A long strip connecting groove 11 is machined on the connecting seat 7 along the direction of movement of the driven component 4. The connecting groove 11 is an open groove machined at both ends of the connecting seat 7. The drive component 3 is connected to a connecting post 9 that mates with the connecting groove 11. For ease of installation, the drive component 3 is also connected to a clamp 8, which is connected to the connecting post 9. Adjusting the installation position of the clamp 8 on the drive component 3 can adjust the installation position of the drive component 3 and the connecting seat 7, thereby adjusting the distance between the drive component 3 and the window sash 2, i.e., the initial extension length of the driven component 4. An anti-slip layer 10 is installed between the clamp 8 and the drive component 3. The anti-slip layer 10 is a 2mm thick vulcanized rubber layer that protects the drive component 3 and provides greater friction.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
