Description
Technical Field
[0001] This utility model belongs to the technical field of fireproof roller shutter doors, specifically relating to a self-cleaning and noise reduction mechanism for fireproof roller shutter door guide rails. Background Technology
[0002] Fire-resistant roller shutters, as important fire-resistant partitions in buildings, are widely used in various industrial and civil buildings. Their guide rails play a crucial guiding and supporting role in the operation of the roller shutter. However, in actual use, the guide rails face several problems. On the one hand, the guide rails are exposed to the environment for extended periods, easily accumulating dust and debris. These contaminants not only affect the smooth operation of the roller shutter but may also accelerate wear between the curtain and the guide rail, reducing the service life of the roller shutter. On the other hand, the friction between the curtain and the guide rail during the raising and lowering of the roller shutter generates significant noise, especially in densely populated areas or environments with high noise control requirements, where this noise interference is particularly noticeable.
[0003] Currently, fire-resistant roller shutter door guide rails on the market lack effective self-cleaning and noise reduction methods. While some products incorporate cleaning or noise reduction functions, they are often single-function designs, unable to simultaneously meet the dual requirements of self-cleaning and noise reduction. Some methods rely on regular manual cleaning, which is not only labor-intensive and time-consuming but also lacks guaranteed cleaning effectiveness, failing to address the noise issue during roller shutter door operation.
[0004] Therefore, developing a mechanism that can automatically clean the guide rails and effectively reduce operating noise is of great significance for improving the performance and user experience of fireproof roller shutters. Utility Model Content
[0005] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a self-cleaning and noise reduction mechanism for fireproof rolling shutter door guide rails, so as to solve the technical defects of existing fireproof rolling shutter door guide rails lacking effective self-cleaning and noise reduction methods.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning noise reduction mechanism for fireproof roller shutter door guide rails, comprising a limiting noise reduction component installed on the inner wall of the groove of the fireproof roller shutter door guide rail and a cleaning component for self-cleaning the limiting noise reduction component, wherein the limiting noise reduction component contacts the side end of the roller shutter, and the cleaning component contacts the limiting noise reduction component.
[0007] As a further preferred embodiment of this utility model, the limiting noise reduction component includes support rods that are detachably installed on the inner walls of both sides of the guide rail groove. A fixing rod is fixedly installed on the support rod, and a bearing is sleeved on the fixing rod. The inner ring of the bearing is fixedly sleeved on the fixing rod, and an elastic rubber ring is fixedly sleeved on the outer ring of the bearing. The elastic rubber ring is in contact with the side end face of the roller shutter.
[0008] As a further preferred embodiment of this utility model, the surface of the elastic rubber ring is coated with a wear-resistant coating, which is a polytetrafluoroethylene coating with a coating thickness of 0.1 to 0.3 mm.
[0009] As a further preferred embodiment of the present invention, the cleaning component includes cleaning plates that are detachably installed on the inner walls of both sides of the guide rail slot. The cleaning plate includes a base plate and brush bristles fixedly installed on the base plate, and the brush bristles are in contact with the surface of the elastic rubber ring.
[0010] As a further preferred embodiment of this utility model, the support rod is fixedly connected to the guide rail by a first bolt;
[0011] The upper and lower ends of the cleaning plate are respectively fixedly connected to the guide rail by the second bolts.
[0012] As a further preferred embodiment of this utility model, the bristles on the cleaning plate are made of nylon.
[0013] As a further preferred embodiment of this utility model, the limiting noise reduction component is provided in multiple sets at equal intervals from bottom to top, and the elastic rubber ring of each set is in contact with the bristles of the cleaning plate.
[0014] Compared with existing technologies, the self-cleaning and noise reduction mechanism for fireproof roller shutter door guide rails provided by this utility model has the following beneficial effects:
[0015] 1. In this utility model, when the roller shutter is raised and lowered by the driving device, it contacts the elastic rubber ring in the guide rail groove through its side end. Since the elastic rubber ring is sleeved on the fixed rod through the bearing, the movement of the roller shutter will drive the elastic rubber ring to roll along the outer ring of the bearing, which transforms the traditional sliding friction of the roller shutter door into rolling friction, reducing friction noise. In addition, the rubber material of the elastic rubber ring itself is elastic, which can buffer the collision force between the curtain and the guide rail when the roller shutter moves, reduce the vibration noise generated by rigid contact, and effectively reduce noise pollution.
[0016] 2. In this utility model, the nylon bristles on the cleaning plate fixed to the inner wall of the guide rail groove are always in contact with the surface of the elastic rubber ring. When the elastic rubber ring rolls with the movement of the roller shutter, the bristles simultaneously wipe its surface back and forth, removing dust, debris and other contaminants from the surface of the elastic rubber ring. In addition, the wear-resistant coating of polytetrafluoroethylene on the surface of the elastic rubber ring is non-stick, making it difficult for dust, oil and other contaminants to adhere. Even if a small amount of contaminants come into contact, they will be more easily removed when the bristles wipe, due to the non-stick nature of the coating. Combined with the mechanical cleaning of the bristles, a dual self-cleaning effect of rolling and wiping is achieved.
[0017] 3. In this utility model, the support rod and the cleaning plate are fixedly connected to the guide rail by the first bolt and the second bolt, respectively, which makes the installation, disassembly and maintenance of the limiting noise reduction component and the cleaning component more convenient. When the mechanism is damaged or its performance deteriorates, it can be quickly replaced, reducing maintenance costs and time costs and improving the practicality of the product.

For example, they can refer to a fixed connection, an integral connection, or a detachable connection; they can refer to the internal connection of two components; they can refer to a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the embodiments of this utility model can be understood according to the specific circumstances.
[0029] Example 1
[0030] Please see Figures 1-5 This utility model provides a technical solution:
[0031] See appendix Figures 1-5 As shown, a self-cleaning noise reduction mechanism for a fireproof roller shutter door guide rail includes: a limiting noise reduction component installed on the inner wall of the groove of the fireproof roller shutter door guide rail 1, and a cleaning component for self-cleaning the limiting noise reduction component. The limiting noise reduction component is in contact with the side end of the roller shutter 7, and the cleaning component is in contact with the limiting noise reduction component.
[0032] Through the above technical solution, by setting a limiting noise reduction component that contacts the side end of the roller shutter 7, the running trajectory of the roller shutter 7 can be restricted, while reducing the friction noise between the roller shutter 7 and the guide rail 1; by setting a cleaning component that contacts the limiting noise reduction component, dust and debris on the surface of the limiting noise reduction component can be automatically removed, avoiding pollutants from affecting its performance, thus realizing the dual functions of self-cleaning and noise reduction of the fireproof roller shutter door guide rail 1, improving the operating stability and service life of the roller shutter door.
[0033] Example 2
[0034] See appendix Figures 1-5 As shown, improvements are made based on Example 1:
[0035] Furthermore, the limiting noise reduction component includes support rods 2 that are detachably installed on the inner walls of both sides of the groove of the guide rail 1. A fixing rod 3 is fixedly installed on the support rod 2. A bearing 4 is sleeved on the fixing rod 3. The inner ring of the bearing 4 is fixedly sleeved on the fixing rod 3. An elastic rubber ring 5 is fixedly sleeved on the outer ring of the bearing 4. The elastic rubber ring 5 is in contact with the side end face of the roller shutter 7.
[0036] Through the above technical solution, the support rod 2, fixing rod 3, bearing 4 and elastic rubber ring 5 installed on the inner wall of the groove of the guide rail 1 form a limiting and noise reduction structure. The bearing 4 can convert the sliding friction between the roller blind 7 and the guide rail 1 into rolling friction, effectively reducing the operating noise. The elastic rubber ring 5 contacts the side end face of the roller blind 7 and uses its own elasticity to provide buffer, further reducing collision noise. At the same time, it plays a limiting and guiding role for the roller blind 7, preventing the roller blind 7 from shifting or shaking during operation.
[0037] Furthermore, the surface of the elastic rubber ring 5 is coated with a wear-resistant coating 8, which is a polytetrafluoroethylene coating with a coating thickness of 0.1 to 0.3 mm.
[0038] With the above technical solution, the coating thickness is preferably 0.2mm. The wear-resistant polytetrafluoroethylene coating applied to the surface of the elastic rubber ring can further reduce the friction between the elastic rubber ring 5 and the roller shutter 7, reduce noise generation, and its excellent non-stick properties make it difficult for dust and dirt to adhere to the surface of the elastic rubber ring 5. With the help of cleaning components, it can achieve self-cleaning more efficiently, extend the service life of the elastic rubber ring 5, and ensure the long-term stability of the limiting noise reduction function.
[0039] Furthermore, the cleaning component includes cleaning plates 6 that are detachably mounted on the inner walls of both sides of the groove of the guide rail 1. The cleaning plate 6 includes a base plate and bristles fixedly mounted on the base plate, and the bristles are in contact with the surface of the elastic rubber ring 5.
[0040] Through the above technical solution, the base plate of the cleaning plate 6 provides stable support for the brush bristles. The brush bristles contact the surface of the elastic rubber ring 5. During the operation of the roller shutter door, the elastic rubber ring 5 rotates and contacts the brush bristles, which can clean the dust and debris on the surface of the elastic rubber ring 5 in time and keep it clean.
[0041] Furthermore, the support rod 2 is fixedly connected to the guide rail 1 by the first bolt 201; the upper and lower ends of the cleaning plate 6 are fixedly connected to the guide rail 1 by the second bolt 601 respectively.
[0042] Through the above technical solution, the support rod 2 and the cleaning plate 6 are fixedly connected to the guide rail 1 by the first bolt 201 and the second bolt 601, respectively, making the installation, disassembly and maintenance of the limit noise reduction component and the cleaning component more convenient. When the mechanism is damaged or its performance deteriorates, it can be quickly replaced, reducing maintenance costs and time costs and improving the practicality of the product.
[0043] Furthermore, the bristles on cleaning plate 6 are made of nylon.
[0044] Through the above technical solution, the nylon bristles on the cleaning plate have good wear resistance and flexibility. They can effectively remove dust and debris from the surface of the elastic rubber ring 5 without damaging the elastic rubber ring 5 and the polytetrafluoroethylene coating on its surface. At the same time, the nylon bristles have high strength and long service life, which can reduce the replacement frequency of cleaning parts and ensure the stable operation of the self-cleaning function.
[0045] Furthermore, multiple sets of limiting and noise-reducing components are provided at equal intervals from bottom to top, and the elastic rubber rings 5 of each set are in contact with the bristles of the cleaning plate 6.
[0046] Through the above technical solution, multiple sets of limiting and noise-reducing components are set at equal intervals from bottom to top, which can provide limiting and noise reduction functions at different height positions of the roller shutter door, enhance the guiding and buffering effect of the roller shutter 7, ensure the smooth operation of the roller shutter door, and ensure that each set of elastic rubber rings 5 is in contact with the bristles of the cleaning plate 6, so that the limiting and noise-reducing components in each part can be cleaned in time during the entire operation of the roller shutter door, and comprehensively improve the performance of the self-cleaning noise reduction mechanism.
[0047] The working principle of this utility model is as follows:
[0048] When the roller shutter 7 is raised and lowered by the drive device, its side end contacts the elastic rubber ring 5 in the groove of the guide rail 1. Since the elastic rubber ring 5 is sleeved on the fixed rod 3 through the bearing 4, the movement of the roller shutter 7 will drive the elastic rubber ring 5 to roll along the outer ring of the bearing 4, which will transform the traditional sliding friction of the roller shutter door into rolling friction, reducing friction noise. In addition, the rubber material of the elastic rubber ring 5 itself is elastic, which can buffer the collision force between the curtain and the guide rail 1 when the roller shutter 7 moves, reducing the vibration noise generated by rigid contact. At the same time, multiple sets of equidistant elastic rubber rings 5 restrict the movement trajectory of the side end of the roller shutter 7 from bottom to top, preventing the roller shutter 7 from deviating or shaking, and ensuring the stability of the raising and lowering process.
[0049] The nylon bristles on the cleaning plate 6, which is fixed to the inner wall of the groove of the guide rail 1, are always in contact with the surface of the elastic rubber ring 5. When the elastic rubber ring 5 rolls with the roller shutter 7, the bristles simultaneously wipe its surface back and forth, removing dust, debris and other contaminants from the surface of the elastic rubber ring 5. In addition, the wear-resistant coating 8 of polytetrafluoroethylene on the surface of the elastic rubber ring 5 is non-stick, making it difficult for dust, oil and other contaminants to adhere. Even if a small amount of contaminants come into contact, they will be more easily removed when the bristles wipe, due to the non-stick nature of the coating. Combined with the mechanical cleaning of the bristles, a dual self-cleaning effect of rolling and wiping is achieved.
[0050] The different embodiments described above can be combined, substituted, or used in combination with each other.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
