Description

Technical Field

[0001] This utility model relates to the field of building fire safety equipment technology, and in particular to a single-track, single-curtain inorganic fabric fireproof roller shutter. Background Technology

[0002] Inorganic fireproof roller shutters are roller shutters made of inorganic materials that can prevent fire. They are mainly made of inorganic fireproof fibers through special processing and have fireproof, smokeproof and heat insulation functions.

[0003] In modern building fire protection systems, fire-resistant roller shutters are widely used in various building projects as important fire-resistant partition facilities. They can quickly descend in the event of a fire to form a physical barrier, controlling the fire within a certain area and preventing the fire from spreading to other areas. However, in actual use, the existing inorganic fabric fire-resistant roller shutters have insufficient flexibility in the installation and fixing methods of the guide rails, making it difficult to adapt to the installation needs of different building environments and resulting in insufficient practicality. Therefore, it is necessary to redesign the single-track single-curtain inorganic fabric fire-resistant roller shutter to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a single-track, single-curtain inorganic fabric fireproof roller shutter.

A support plate is fixedly installed inside the housing. Side plates are fixedly installed on both outer walls of the support plate. A winding roller and a guide roller are rotatably installed inside the two side plates. A fireproof motor connected to the rotating shaft of the winding roller is fixedly installed on the outer wall of one of the side plates. A sliding groove is formed on the outer wall of the winding roller. The roller shutter body is fixedly connected to the sliding groove via a sliding mechanism. A buffer block is fixedly installed at the end of the roller shutter body. A counterweight is fixedly installed on the outer wall of the buffer block via a mounting groove. An installation plate is fixedly installed on the inner wall of the box. A cleaning brush is fixedly connected to the inner wall of the installation plate through an elastic mechanism.

Guide rails are fixedly installed on the outer walls of the two connecting sleeves. Pins are slidably installed on the bottom walls of the two connecting sleeves. Insertion holes that mate with the pins are opened on the bottom walls of the two connecting rods. Toggle blocks are fixedly installed on the outer walls of the two pins. The upper surfaces of the two toggle blocks are connected to the bottom walls of the connecting sleeves through a fixing mechanism.

[0006] Preferably, the sliding mechanism includes a slider slidably installed inside the slide groove, the roller shutter body is fixedly installed at the end of the slider, and both the slide groove and the slider have a T-shaped cross-section.

[0007] Preferably, the elastic mechanism includes a plurality of spring telescopic rods fixedly installed on the inner wall of the mounting plate, and the telescopic end of each spring telescopic rod is fixedly connected to the outer wall of the cleaning brush.

[0008] Preferably, the fixing mechanism includes a fixing spring installed on the outer wall of the pin, and the two ends of the fixing spring are elastically connected to the bottom wall of the connecting sleeve and the upper end face of the lever, respectively.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-7 A single-track, single-curtain inorganic fabric fireproof roller shutter includes a housing 1. A support plate 2 is fixedly installed inside the housing 1. Side plates 3 are fixedly installed on both outer walls of the support plate 2. A winding roller 4 and a guide roller 5 are rotatably installed inside the two side plates 3. A fireproof motor 6, connected to the rotating shaft of the winding roller 4, is fixedly installed on the outer wall of one side plate 3. A sliding groove is formed on the outer wall of the winding roller 4. A roller shutter body 8 is fixedly connected inside the sliding groove via a sliding mechanism. A buffer block 9 is fixedly installed at the end of the roller shutter body 8. A counterweight block 10 is fixedly installed on the outer wall of the buffer block 9 via an installation groove. The inner wall of the housing 1 is fixed... A mounting plate 11 is fixedly installed. A cleaning brush 13 is fixedly connected to the inner wall of the mounting plate 11 through an elastic mechanism. Two connecting rods 14 are fixedly installed on the bottom wall of the bracket plate 2. Connecting sleeves 15 are slidably installed on the outer walls of the two connecting rods 14. Guide rails 16 are fixedly installed on the outer walls of the two connecting sleeves 15. Pins 17 are slidably installed on the bottom walls of the two connecting sleeves 15. Insertion holes that mate with pins 17 are opened on the bottom walls of the two connecting rods 14. Toggle blocks 18 are fixedly installed on the outer walls of the two pins 17. The upper surfaces of the two toggle blocks 18 are connected to the bottom walls of the connecting sleeves 15 through a fixing mechanism.

[0016] Furthermore, the connecting sleeve 15 and the guide rail 16 are connected by welding. Before the guide rail 16 is installed, the welding position between the connecting sleeve 15 and the guide rail 16 can be determined according to the installation requirements.

[0017] The sliding mechanism includes a slider 7 that is slidably installed inside the slide groove, and the roller shutter body 8 is fixedly installed at the end of the slider 7. Both the slide groove and the slider 7 have a T-shaped cross section.

[0018] Furthermore, the T-shaped cross-section design allows the slider 7 to slide only in a specific direction within the groove, effectively limiting its lateral and longitudinal movement and greatly improving the stability of the connection between the roller shutter body 8 and the winding roller 4.

[0019] The elastic mechanism includes multiple spring telescopic rods 12 fixedly installed on the inner wall of the mounting plate 11, and the telescopic end of each spring telescopic rod 12 is fixedly connected to the outer wall of the cleaning brush 13.

[0020] Furthermore, multiple spring telescopic rods 12 are equidistantly distributed on the inner wall of the mounting plate 11, which can provide uniform elastic support for the cleaning brush 13, ensuring that the cleaning brush 13 is always in close contact with the surface of the roller blind during the operation of the roller blind.

[0021] The fixing mechanism includes a fixing spring 19 installed on the outer wall of the pin 17. The two ends of the fixing spring 19 are elastically connected to the bottom wall of the connecting sleeve 15 and the upper end face of the lever 18, respectively.

[0022] Furthermore, the fixed spring 19 is made of high-elasticity stainless steel, which has good corrosion resistance and a stable elastic coefficient, and is not prone to fatigue failure during long-term use.

[0023] The inner walls of both sides of the two guide rails 16 are provided with guide grooves, and multiple guide wheels 20 are rotatably installed inside each guide groove.

[0024] Furthermore, the shape and size of the guide groove match the guide wheel 20, ensuring that the guide wheel 20 can rotate flexibly within the guide groove while restricting its lateral movement, providing precise guidance for the roller blind body 8. The guide wheel 20 adopts a structure of wear-resistant rubber wrapped around a metal hub, and the rubber surface has an anti-slip texture, which can reduce the friction between the roller blind and the guide wheel 20, and increase the friction between the two, preventing the roller blind from slipping during operation. Multiple guide wheels 20 are evenly distributed within the guide groove, forming a multi-point support structure, which effectively disperses the weight of the roller blind body 8 and the pressure generated during operation, making the roller blind more stable during lifting and lowering, and reducing the occurrence of shaking and jamming.

[0025] In use, the slider 7 can be slidably installed inside the groove, thereby connecting the roller blind body 8 and the winding roller 4. The roller blind body 8 is then placed on the outer wall of the guide roller 5. Subsequently, the two connecting sleeves 15 can be slidably installed on the outer walls of the two connecting rods 14 respectively. After the sliding installation of the connecting sleeves 15 and the connecting rods 14 is completed, the pin 17 is inserted into the corresponding hole by pressing the toggle block 18 to achieve quick positioning and locking of the guide rail 16. The continuous elastic pressure of the toggle block 18 by the fixing spring 19 ensures that the pin 17 will not loosen during long-term use, effectively avoiding the risk of roller blind jamming caused by the displacement of the guide rail 16. After the slider 7 and the roller blind body 8 are installed, the fireproof motor 6 is started. The motor drives the winding roller 4 to rotate. Since the roller blind body 8 is connected to the winding roller 4 through the slider 7, the slider 7 will move synchronously along the groove when the winding roller 4 rotates, thereby achieving smooth winding and lowering of the roller blind body 8.

[0026] During the lowering process of the roller blind, the roller blind body 8 can move along the multiple guide wheels 20 on both sides. With the cooperation of the multiple guide wheels 20 on both sides, the wear of the roller blind body 8 during the unwinding process can be reduced. The buffer block 9 at the end of the roller blind body 8 and the counterweight block 10 cooperate with each other. The counterweight block 10 uses its own weight to accelerate the lowering speed of the roller blind, ensuring that a fire barrier can be quickly formed in the event of a fire. The buffer block 9 effectively reduces the impact when the roller blind is lowered to the bottom, protecting the roller blind body 8 and related components. At the same time, the spring telescopic rod 12 and the cleaning brush 13 on the mounting plate 11 inside the housing 1 play their roles. The spring telescopic rod 12 always maintains an elastic thrust on the cleaning brush 13, so that the cleaning brush 13 is in close contact with the surface of the roller blind body 8. During the roller blind rewinding process, the cleaning brush 13 will promptly remove dust, debris and other impurities attached to the roller blind, preventing the accumulation of debris from affecting the normal operation and fire resistance of the roller blind, and extending the service life of the roller blind.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
