Description

Technical Field

[0001] The utility model relates to a rolling shutter door accessory device, in particular to a steel fireproof rolling shutter matching device. Background Art

[0002] Steel fireproof roller shutters are widely used in large complexes, underground parking lots, shops and other buildings. They not only have the traditional anti-theft function, but also can block the rapid spread of fire in the event of a fire, providing time for people to escape. Steel fireproof roller shutters include steel curtain surfaces and steel guide rails. Under the action of the rolling door machine and the reel, the curtain surface moves up and down inside the guide rail. Due to the large curtain surface area of ​​the fireproof roller shutter, there will be sliding friction with the inner side of the guide rail during the movement. Since both are made of steel, the curtain surface of the conventional fireproof roller shutter will produce harsh noise during the up and down movement, which not only causes noise pollution and reduces the user experience, but also causes the curtain surface to be unbalanced left and right as the use time increases, making the noise problem more serious and affecting the service life of the curtain surface.

[0003] Therefore, there is an urgent need for a new type of supporting device for steel fireproof roller shutters, which can reduce the noise pollution during the movement of the curtain surface, extend the service life of the curtain surface, and has a simple structure, which is convenient for upgrading and transforming the conventional steel fireproof roller shutters. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a steel fireproof roller shutter matching device, which can reduce the noise pollution during the movement of the curtain surface, extend the service life of the curtain surface, and has a simple structure, which is convenient for upgrading and transforming the conventional steel fireproof roller shutter.

[0005] The utility model adopts the following technical solutions:

[0006] A steel fireproof rolling shutter matching device comprises a curtain surface, a reel, a rolling door machine driving the reel, a motor plate for installing the reel and the rolling door machine, and a guide rail for guiding the curtain surface. A plurality of rolling mechanisms are arranged on the inner side surfaces of the guide rail relative to the front, back and side surfaces of the curtain surface.

[0007] The rolling mechanism adopts one of two schemes:

[0008] The first type: the rolling mechanism includes a U-shaped groove body opened inside the guide rail, a U-shaped support body sleeved inside the groove body, a first compression spring arranged inside the groove body for supporting the support body, and a roller with a cylindrical structure rotatably arranged on the support body. The support body includes a supporting body with a square structure located inside the groove body and support frames located at both ends of the supporting body. The support frame is passed through the groove body to the outside of the guide rail, and the roller is rotatably arranged between the two support frames; the roller is made of engineering plastic material, preferably one of polyamide, polycarbonate, polyformaldehyde and polyphenylene ether; when the first spring is in a non-deformed state, the distance between the roller and the outer surface of the curtain face is between 10 and 20 mm.

[0009] The second type: The rolling mechanism includes a spherical mounting groove opened on the surface of the guide rail, a spherical mounting shell sleeved on the mounting groove, and a ball rolling on the mounting shell. The ball is made of engineering plastic, preferably one of polyamide, polycarbonate, polyoxymethylene and polyphenylene ether.

[0010] When the second solution is adopted, in order to further reduce the noise generated and extend the service life of the ball, a support groove connected to the mounting groove is opened inside the guide rail, and a second compression spring connected to the mounting shell is arranged in the support groove; the ball is made of engineering plastic material, preferably one of polyamide, polycarbonate, polyformaldehyde and polyphenylene ether; when the second spring is in a state of no deformation, the distance between the ball and the outer surface close to the curtain face is between 10 and 20 mm.

[0011] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages: 1. The utility model sets a rolling mechanism, so that the traditional sliding friction between the curtain surface and the guide rail is replaced by rolling friction during the relative movement, which greatly reduces the noise generated by the steel curtain surface and the steel guide rail, and also effectively reduces the left and right height imbalance of the curtain surface caused by friction, thereby extending the service life of the curtain surface and improving the user experience; 2. The utility model is an improvement in the guide rail, with a simple structure. The existing fireproof roller shutter can be upgraded and renovated by replacing only two guide rails without replacing the main accessories, such as the rolling door machine and the curtain surface on a large scale. The cost is low and the renovation operation is simple. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The specific implementation of the present utility model is described below with reference to the accompanying drawings.

[0024] Embodiment 1:

[0025] See also Figures 1 to 6 A steel fireproof rolling shutter matching device includes a curtain surface 1, a roller 2, a rolling door machine 3 for driving the roller 2, a motor plate 4 for installing the roller 2 and the rolling door machine 3, and a guide rail 5 for guiding the curtain surface 1. A plurality of rolling mechanisms 6 are arranged on the inner side surfaces of the guide rail 5 relative to the front, back and side surfaces of the curtain surface 1.

[0026] The rolling mechanism 6 includes a U-shaped groove body 71 opened inside the guide rail 5, a U-shaped support body 72 sleeved inside the groove body 71, a first compression spring 73 arranged inside the groove body 71 for supporting the support body 72, and a roller 74 with a cylindrical structure rotatably arranged on the support body 72. The number of the first compression springs 73 is two. The support body 72 includes a support body 721 with a square structure located inside the groove body 71 and support frames 722 located at both ends of the support body 721. The support frames 722 are penetrated to the outside of the guide rail 5, and the roller 74 is rotatably arranged between the two support frames 722; the roller 74 is made of engineering plastic material, preferably one of polyamide, polycarbonate, polyoxymethylene and polyphenylene ether; when the first compression spring 73 is in a non-deformed state, the distance between the roller 74 and the outer surface of the curtain surface 1 is between 10 and 20 mm.

[0027] Embodiment 2:

[0028] See also Figure 1 , Figure 2 , Figures 7 to 11 A steel fireproof rolling shutter matching device includes a curtain surface 1, a roller 2, a rolling door machine 3 for driving the roller 2, a motor plate 4 for installing the roller 2 and the rolling door machine 3, and a guide rail 5 for guiding the curtain surface 1. A plurality of rolling mechanisms 6 are arranged on the inner side surfaces of the guide rail 5 relative to the front, back and side surfaces of the curtain surface 1.

[0029] The rolling mechanism 6 includes a spherical mounting groove 81 provided on the surface of the guide rail 5, a spherical mounting shell 82 sleeved on the mounting groove 81, and a ball 83 rolling on the mounting shell 82. The ball 83 is made of engineering plastic material, preferably one of polyamide, polycarbonate, polyoxymethylene and polyphenylene ether.

[0030] In order to further reduce the noise generated and extend the service life of the ball 83, a support groove 9 connected to the mounting groove 81 is opened inside the guide rail 5, and a second compression spring 91 connected to the mounting shell 82 is arranged in the support groove 9; the ball 83 is made of engineering plastic material, preferably one of polyamide, polycarbonate, polyformaldehyde and polyphenylene ether; when the second compression spring 91 is in a state of no deformation, the distance between the ball 83 and the outer surface of the curtain surface 1 is between 10 and 20 mm.

[0031] Working principle: The steel curtain surface 1 and the steel guide rail 5 of the conventional steel fireproof roller shutter are in sliding friction, and since both are made of steel, the noise generated by the friction is very harsh, and the long-term sliding friction also makes it easy for the left and right ends of the curtain surface 1 to have a height imbalance, which not only affects the service life of the curtain surface 1, but also further increases the noise; the utility model improves the guide rail 5, and a rolling mechanism 6 is provided in the guide rail 5, so that there is rolling friction between the curtain surface 1 and the guide rail 5, and the friction force is greatly reduced, thereby reducing the generation of noise. At the same time, the application of engineering plastic materials further reduces the noise, and at the same time, the setting of the compression spring can not only effectively buffer the impact force caused by the curtain surface 1 on the roller 74 or the ball 83 in the rolling mechanism 6, but also further reduce the generation of noise; at the same time, the utility model has a simple structure and low cost, and the user only needs to replace the guide rail 5 in the existing steel fireproof roller shutter or add a rolling mechanism 6 to achieve the effect of reducing noise, which is convenient for users to upgrade and transform existing equipment.

[0032] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
