Description

Technical Field

[0001] This utility model belongs to the field of building door and window automation control technology, specifically an anti-bend chain window opener. Background Technology

[0002] With the rapid development of building intelligence and home automation, window openers, as an important type of automated equipment, have been widely used in various scenarios, including residences, office buildings, industrial plants, and public facilities. Chain-type window openers, due to their simple structure, convenient installation, and wide applicability, have become one of the mainstream products on the market. However, in practical use, existing chain-type window openers still have some technical problems that urgently need to be solved.

[0003] Currently, chain-type window openers on the market commonly suffer from chain bending and deformation during long-term use. This not only significantly shortens the lifespan of the opener but also reduces stability during opening and closing, affecting ease of operation and safety. For example, patent CN109356480B discloses a window opener that improves fixation and stability through a structure combining a telescopic block and a rotating inner shaft. However, due to the lack of special protection for the chain, it is still prone to bending and deformation after prolonged use, thus affecting overall performance. Furthermore, this design is complex to install and maintain, increasing user costs and limiting its widespread application.

[0004] Another patent document, CN113622780B, describes a chain-type electric window opener that uses a separate assembly structure of positioning blocks, support blocks, and connecting blocks, improving the convenience and stability of installation. However, this design also fails to effectively solve the problem of chain bending and deformation, and the chain, being exposed to the external environment for a long time, is susceptible to corrosion and wear, further reducing the service life and reliability of the window opener.

[0005] In summary, existing chain-type window openers have significant shortcomings in terms of anti-bending performance, durability, and environmental adaptability, making it difficult to meet users' actual needs for high efficiency, stability, and long-term use. Therefore, developing a chain-type window opener that can effectively prevent chain bending and deformation, extend service life, and enhance stability has significant technical importance and market value. Utility Model Content

[0006] To address the technical problem mentioned in the background art that chain-type window openers are prone to chain bending and deformation during long-term use, leading to shortened service life and poor stability, this invention provides an anti-bending chain window opener to improve the chain's bending resistance and overall stability. To achieve the above objective, the specific technical solution of this invention's anti-bending chain window opener is as follows: An anti-bending chain window opener includes a drive device, a chain, and a guide assembly. The chain is connected to the drive device, and the guide assembly is disposed on both sides of the chain. An anti-bending support is provided between the guide assembly and the chain. One end of the anti-bending support is fixed to the guide assembly, and the other end abuts against the outer surface of the chain to restrict the chain's lateral displacement.

[0007] Furthermore, the guide assembly includes a first guide plate and a second guide plate, which are located on both sides of the chain, and are fixedly connected by a connecting rod to form a stable frame structure for the guide assembly.

[0008] Furthermore, both the first guide plate and the second guide plate are provided with multiple mounting holes, which are evenly distributed along the length of the guide plate. The anti-bending support is fixed to the first guide plate and the second guide plate through the mounting holes.

[0009] Furthermore, the anti-bending support includes a first support block and a second support block, which are respectively disposed on both sides of the chain. The inner surfaces of the first support block and the second support block are provided with arc-shaped grooves, which match the outer surface of the chain to achieve effective support for the chain.

[0010] Furthermore, both the first and second support blocks are equipped with adjusting bolts. The adjusting bolts pass through the support blocks and are threadedly connected to the mounting holes to make the position of the anti-bending support adjustable.

[0011] Furthermore, the outer surface of the chain is coated with a wear-resistant coating made of polymer materials to improve the chain's corrosion resistance and wear resistance.

[0012] Furthermore, the drive unit includes a motor and a sprocket. The sprocket is meshed with the chain, and the motor drives the sprocket to rotate through a drive shaft, thereby driving the chain to move.

[0013] Furthermore, both ends of the guide assembly are provided with end limiting blocks, which are fixed to the first guide plate and the second guide plate to prevent the chain from detaching from the guide assembly during movement.

[0014] Furthermore, the curved groove of the anti-bending support is provided with an elastic gasket, which is made of rubber material to reduce the friction between the chain and the anti-bending support.

[0015] Furthermore, both the inner surfaces of the first and second guide plates are provided with lubrication grooves, which extend along the length of the guide plates and are filled with grease to reduce the frictional resistance between the chain and the guide plates.

[0016] The anti-bending chain window opener of this utility model has the following advantages: By setting guide components and anti-bending supports on both sides of the chain, the lateral displacement of the chain is effectively limited, preventing the chain from bending and deforming during long-term use, thereby extending the service life of the window opener; the position of the anti-bending supports is adjustable, which can adapt to chains of different specifications, improving the versatility of the device; the wear-resistant coating and elastic pads on the outer surface of the chain significantly improve the corrosion resistance and wear resistance of the chain, while reducing frictional resistance during operation; the lubrication groove of the guide component further reduces the friction between the chain and the guide plate, improving the stability and smoothness of the window opener's operation.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] This utility model provides an anti-bend chain window opener, the specific implementation of which is described in conjunction with the attached diagram. Figure 1 To be continued Figure 3 Please provide a detailed explanation. For example... Figure 1 and Figure 2 As shown, the anti-bend chain window opener includes a drive unit 1, a chain 2, and a guide assembly 3. The chain 2 is connected to the drive unit 1 and is used to transmit power to achieve the window opening function. The guide assembly 3 is located on both sides of the chain 2 and is used to restrict and guide the movement trajectory of the chain 2. An anti-bend support 4 is provided between the guide assembly 3 and the chain 2. One end of the anti-bend support 4 is fixed to the guide assembly 3, and the other end abuts against the outer surface of the chain 2, thereby effectively restricting the lateral displacement of the chain 2 and preventing the chain 2 from bending and deforming during long-term use.

[0025] The specific structure of drive device 1 is as follows: Figure 2As shown, it includes a motor 11, a sprocket 12, and a drive shaft 13. The motor 11 drives the sprocket 12 to rotate via the drive shaft 13. The sprocket 12 meshes with the chain 2, thereby transmitting the power of the motor 11 to the chain 2, causing the chain 2 to move in a predetermined direction. The chain 2 drives the output sprocket, which in turn drives the output shaft mounted on it to rotate. This design ensures the smooth movement of the chain 2 while improving the overall operating efficiency of the window opener. To further enhance the durability of the chain 2, a wear-resistant coating 21 is provided on the outer surface of the chain 2. This wear-resistant coating 21 is made of a polymer material and has excellent corrosion resistance and wear resistance, which can significantly extend the service life of the chain 2.

[0026] The specific structure of guide component 3 is as follows: Figure 2 As shown, it includes a first guide plate 31 and a second guide plate 32, which are located on both sides of the chain 2 and fixedly connected by a connecting rod 33 to form a stable frame structure. This frame structure not only enhances the overall rigidity of the guide assembly 3 but also provides reliable guiding support for the chain 2. Both the first guide plate 31 and the second guide plate 32 are provided with multiple mounting holes 34, which are evenly distributed along the length of the guide plate for fixing the anti-bending support member 4. By adjusting the position of the anti-bending support member 4 in the mounting holes 34, it can accommodate chains 2 of different specifications, thereby improving the versatility of the device.

[0027] The specific structure of the anti-bending support 4 is as follows: Figure 2 and Figure 3 As shown, it includes a first support block 41 and a second support block 42, which are respectively disposed on both sides of the chain 2. The inner surfaces of both the first support block 41 and the second support block 42 are provided with arc-shaped grooves 43, the shape of which matches the outer surface of the chain 2, thereby achieving effective support for the chain 2. To reduce the friction between the chain 2 and the anti-bending support 4, an elastic pad 45 is provided inside the arc-shaped groove 43. The elastic pad 45 is made of rubber material and has good elasticity and wear resistance. Furthermore, both the first support block 41 and the second support block 42 are provided with adjusting bolts 44. The adjusting bolts 44 pass through the support blocks and are threadedly connected to the mounting holes 34. By tightening or loosening the adjusting bolts 44, the position of the anti-bending support 4 can be adjusted to ensure it always fits tightly against the outer surface of the chain 2, thereby further improving the bending resistance of the chain 2.

[0028] To prevent the chain 2 from detaching from the guide assembly 3 during operation, end limiting blocks 35 are provided at both ends of the guide assembly 3. These end limiting blocks 35 are fixed to the first guide plate 31 and the second guide plate 32, serving a limiting function. Furthermore, lubrication grooves 5 are provided on the inner surfaces of both the first guide plate 31 and the second guide plate 32. These grooves extend along the length of the guide plate and are filled with grease. The lubrication grooves 5 effectively reduce the frictional resistance between the chain 2 and the guide plates, thereby improving the stability and smoothness of the window opener's operation.

[0029] In practical applications, the working principle of this anti-bend chain window opener is as follows: When the window needs to be opened, the motor 11 starts and drives the sprocket 12 to rotate through the transmission shaft 13. The sprocket 12 engages with the chain 2, thereby driving the chain 2 to move along the track of the guide assembly 3. Due to the frame structure of the guide assembly 3 and the presence of the anti-bend support 4, the chain 2 is strictly restricted laterally during movement, avoiding bending deformation caused by external loads or long-term use. At the same time, the wear-resistant coating 21 on the outer surface of the chain 2 and the elastic pad 45 in the arc-shaped groove 43 work together to significantly reduce the wear of the chain 2 and extend its service life. In addition, the grease in the lubrication groove 5 further reduces the frictional resistance between the chain 2 and the guide plate, making the window opener run more smoothly and efficiently.

[0030] In summary, the anti-bending chain window opener of this utility model effectively limits the lateral displacement of the chain 2 by setting guide components 3 and anti-bending support members 4 on both sides of the chain 2, preventing the chain 2 from bending and deforming during long-term use, thereby extending the service life of the window opener. The position of the anti-bending support member 4 is adjustable, which can adapt to chains 2 of different specifications, improving the versatility of the device. The wear-resistant coating 21 and elastic gasket 45 on the outer surface of the chain 2 significantly improve the corrosion resistance and wear resistance of the chain 2, while reducing frictional resistance during operation. The lubrication groove 5 of the guide component 3 further reduces the friction between the chain 2 and the guide plate, improving the stability and smoothness of the window opener's operation. These technical features together constitute the core innovation of this utility model, enabling it to exhibit excellent performance and reliability in practical applications.
