Description

Technical Field

[0001] This utility model relates to the field of window opener equipment technology, specifically an improved chain window opener. Background Technology

[0002] A chain window opener is a device that uses the extension and retraction of a chain to drive the opening and closing of a window. It is widely used in smart homes, fire exhaust systems, greenhouses, and industrial plants. It typically consists of a motor, a reduction gear, a chain, and window connectors. The motor drives the chain to extend or retract, thereby opening or closing the window. Depending on the number of chains, it can be divided into single-chain and double-chain types. Chain window openers are characterized by easy installation, simple operation, and strong applicability. They can also achieve remote control, intelligent control, obstacle detection stop, and overload protection functions. The chain is usually made of high-strength metals such as stainless steel, and the outer shell is made of weather-resistant materials such as aluminum alloy to ensure its durability and adaptability.

[0003] An investigation revealed that a single-chain window opener (publication number: CN222414525U) is disclosed in Chinese utility model, comprising a window opener body, a chain assembly, and a window sash connecting plate. The window opener body is installed on the lower frame of the window frame, and the window sash connecting plate is installed on the lower frame of the window sash. The first end of the chain assembly is located inside the window opener body, and the second end is fixedly connected to the window sash connecting plate. The window opener body has a chain cavity, and the chain assembly includes a chain located inside the chain cavity. The window opener body has a chain outlet, and the first end of the chain extends through the chain outlet to the outside of the window opener body and connects to the window sash connecting plate, while the second end is fixed inside the window opener body.

[0004] Although the aforementioned patent controls the movement of the chain within the chain cavity to adjust the length of the chain extending outside the window opener body, thereby driving the movement of the window sash connecting plate and thus the window sash, achieving the opening and closing of the window, it has the advantages of simple structure, convenient opening and closing, and easy maintenance. However, the pushing and pulling force of the chain window opener is relatively small. For heavy windows or windows requiring a large opening angle, the chain may form an arc shape under heavy pressure or when the extension length is too long, which can easily cause excessive local stress and breakage. Furthermore, prolonged bending can easily deform the window frame. In addition, if dust or foreign objects accumulate on the chain surface, there will be a large friction during operation, which can easily cause wear.

[0005] Therefore, this utility model provides an improved chain window opener to solve the above problems. Utility Model Content

Detailed Implementation

[0027] 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 protection scope of the present utility model.

[0028] This utility model provides an improved chain window opener, such as... Figures 1-5 As shown, an improved chain window opener includes a mounting box 1, a pushing component is fixedly installed inside the mounting box 1, and a care component is fixedly connected to the edge of the upper surface of the mounting box 1.

[0029] The pushing component includes a first motor 2, the outer surface of which is fixedly installed inside the mounting box 1. A first gear 3 is fixedly connected to the output end of the first motor 2. A second gear 4 meshes with the outer surface of the first gear 3. A sprocket 5 is fixedly connected to the upper surface of both the first gear 3 and the second gear 4. A chain 6 meshes with the outer surface of the sprocket 5. When an external power source starts the first motor 2, it drives the first gear 3 to rotate, and the second gear 4 rotates synchronously in opposite directions, thereby causing the sprocket 5 to rotate and the two chains 6 to run synchronously. The bending surfaces of the two chains 6 are arranged opposite each other and mutually limit each other, so that the chains 6 run straight. On the one hand, this can strengthen the load-bearing capacity of the chains 6, improve their pushing and pulling stability, and increase their pushing and pulling force to adapt to heavy windows. On the other hand, it can prevent the chains 6 from bending, which would cause excessive local stress and breakage. It can also reduce friction, reduce the wear rate, improve service life, and prevent deformation of the window frame.

[0030] The care component includes a guide box 7. One side of the lower surface of the guide box 7 is fixedly connected to the edge of the upper surface of the mounting box 1. An oil storage box 8 is fixedly connected to the upper surface of the guide box 7, and a collection box 9 is fixedly connected to the other side of the lower surface of the guide box 7. Mounting plates 10 are fixedly connected to the edges of the front surfaces of both the oil storage box 8 and the collection box 9. Brush bristles 11 are fixedly connected to the inner side of the mounting plate 10. During the extension and retraction of the chain 6, it passes through the guide box 7. The lubricating oil inside the oil storage box 8 permeates to the surface of the chain 6 to lubricate it, thereby reducing friction and wear. When too much lubricating oil seeps out, it will fall freely below the chain 6 and be carried into the collection box 9 during the removal of the chain 6, thus avoiding contamination of the installation area. The brush bristles 11 can wipe the lubricating oil evenly and remove dust or foreign matter from its surface, further reducing the stress on the chain 6.

[0031] The upper surface of the guide box 7 is provided with a first square groove in the middle of the oil storage box 8. A penetrating cotton 12 is fixedly connected inside the first square groove. The lower surface of the guide box 7 is provided with a second square groove in the middle of the collection box 9. The penetrating cotton 12 can ensure the uniform overflow of lubricating oil, and the second square groove facilitates the entry of excess lubricating oil into the collection box 9.

[0032] One end of the chain 6 is fixedly connected to a first fixing block 14 via a bolt 13. Both sides of the first fixing block 14 are rotatably connected to a first mounting bracket 15 via a first rotating rod. The bolt 13 facilitates the connection between the chain 6 and the first fixing block 14. The first fixing block 14 and the first mounting bracket 15 are rotatably connected, which makes it easy for the chain 6 to adapt to the angle changes when the window is opened and closed.

[0033] The upper surface of the mounting box 1 is fixedly connected to the box body 16, and the upper surface of the box body 16 is connected to the box cover 17 by screw threads. The box body 16 facilitates the storage of the chain 6. By unscrewing the screws and removing the box cover 17, it is convenient to inspect and repair the internal components of the box body 16.

[0034] The lower surface of the box 16 is fixedly connected to both sides of the second fixing block 18. The second fixing block 18 is rotatably connected to the second mounting bracket 19 through the second rotating rod. The second fixing block 18 and the second mounting bracket 19 are rotatably connected, which makes it easy for the box 16 to adapt to the angle change when the window is opened and closed, and ensures the flexibility of the device.

[0035] The upper surface of the oil storage box 8 is fixedly connected to the inlet 20, and the bottom end of the inlet 20 is inserted with a sealing plug 21. Lubricating oil can be easily added into the oil storage box 8 through the inlet 20, and then sealed with the sealing plug 21 to prevent spillage.

[0036] Working steps: First, fix the second mounting bracket 19 to the windowsill, then fix the first mounting bracket 15 to the window frame. Add lubricating oil into the oil storage box 8 through the feed port 20, and then seal it with the sealing plug 21. Next, start the first motor 2 with the external power supply to drive the first gear 3 to rotate, and the second gear 4 to rotate synchronously in opposite directions, thereby rotating the sprocket 5 and making the two chains 6 run synchronously. The bending surfaces of the two chains 6 are set opposite each other and mutually limit each other, so that the chains 6 run straight. Second, during the extension and retraction of the chains 6, they enter and exit through the guide box 7. The lubricating oil inside the oil storage box 8 permeates to the surface of the chains 6 through the penetrating cotton 12 to lubricate them. When too much lubricating oil seeps out, it will fall freely to the bottom of the chains 6. During the removal of the chains 6, it will be carried into the collection box 9. Finally, the brush bristles 11 can wipe the lubricating oil evenly and remove dust or foreign objects from the surface. By unscrewing the screws, the box cover 17 can be removed to facilitate the inspection and maintenance of the internal parts of the box body 16.
