Description

Technical Field

[0001] This utility model relates to the field of high-speed door technology, and in particular to a silent door module for a high-speed door. Background Technology

[0002] The turbine-mounted rigid high-speed door is a high-performance industrial door that combines turbine track technology with a rigid door panel. It is widely used in factories, warehouses, garages, and other similar applications, featuring rapid opening and closing, wind resistance, heat insulation, and intelligent protection. Its guide rail system includes two tracks designed with an Archimedean spiral. The door body rolls up without contact under the action of the power system, achieving a lifting speed of up to 0.8 meters per second. Simultaneously, guide pulleys are installed on both sides of the door body, slidingly connected within the tracks to reduce friction.

[0003] High-speed doors have a fast lifting speed, which leads to increased noise during rapid operation. Therefore, it is necessary to implement noise reduction measures for each operating component. This application focuses on the noise reduction design of the door module (a partial module that constitutes the overall door panel) to reduce the noise generated during the operation of the door panel. Utility Model Content

[0004] The purpose of this invention is to provide a silent door module for a high-speed door, which reduces operating noise.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a silent door module for a high-speed door, comprising multiple door panels arranged vertically and hinged together at their joints, two side-mounted hinge assemblies, and multiple guide wheels disposed on the side-mounted hinge assemblies and corresponding to the hinge joints of the door panels. The side-mounted hinge assemblies are installed at the ends of the multiple door panels to achieve hinged connection at the joints of the multiple door panels. Each side-mounted hinge assembly includes multiple fixed plates installed on the side of the door panel and a hinge structure disposed between two adjacent fixed plates. The hinge structure includes a lower... The system comprises a first pivot at the top of a fixed plate, a nylon sleeve mounted on the first pivot, and a connecting plate with one end fixed to the bottom of the upper fixed plate and the other end fitted onto the nylon sleeve; the guide wheel is made of polyurethane material and is rotatably connected to the end of the first pivot away from the fixed plate; an intermediate hinge is provided between two adjacent door panels, the intermediate hinge comprising an upper hinge plate mounted on one door panel, a lower hinge plate mounted on the other door panel, and a second pivot between the upper hinge plate and the lower hinge plate, both of which are made of nylon material.

[0006] By adopting the above technical solutions, firstly, the guide wheel is made of polyurethane material, which has moderate softness and hardness, thereby reducing the noise generated when sliding in the guide rail; secondly, a nylon sleeve is fitted on the first pivot of the side-mounted hinge assembly, which can reduce the noise generated during the rotation of the two fixed plates of the side-mounted hinge assembly; at the same time, an intermediate hinge is installed between two adjacent door panels, and both the upper and lower hinge plates of the intermediate hinge are made of nylon material, which can also reduce operating noise; finally, for the door module, the noise reduction design of the intermediate hinge at the connection between adjacent door panels, the noise reduction design of the nylon sleeve at the first pivot of the side-mounted hinge assembly, and the noise reduction design of the guide wheel made of polyurethane material have the effect of reducing operating noise.

[0007] A further feature of this invention is that the hinge structure includes a connecting shaft disposed at the bottom of the upper fixing plate and passing through the connecting plate, a connecting nut threaded to one end of the connecting shaft passing through the connecting plate, and a positioning bolt threaded to the upper fixing plate after passing through the connecting plate.

[0008] By adopting the above technical solution, the upper end of the connecting plate is fixed with a connecting shaft and a connecting nut, and fixed with positioning bolts, thereby ensuring the structural stability of the connecting plate and the upper fixing plate after installation.

[0009] A further feature of this invention is that, between two adjacent door panels, the bottom of the upper door panel is provided with a groove, and the top of the upper door panel is provided with a protrusion located within the groove. When the two door panels are arranged in parallel, the protrusion is embedded in the groove. When the relative angle of the two door panels rotates, the protrusion of the lower door panel does not interfere with the groove of the upper door panel.

[0010] By adopting the above technical solution, and by setting a groove and a protrusion between the two door panels, the tightness of the connection between the two door panels is improved.

[0011] A further feature of this invention is that the upper hinge plate is integrally provided with a first limiting part that abuts against the door panel, and the lower hinge plate is integrally provided with a second limiting part that abuts against the door panel. When the first limiting part and the second limiting part abut against each other, the two door panels are arranged in parallel.

[0012] By adopting the above technical solution, when the first limiting part and the second limiting part abut against each other, the two door panels are arranged in parallel. Since the first limiting part and the second limiting part are integrally set with the upper hinge piece and the lower hinge piece respectively, and the first limiting part and the second limiting part are also made of nylon material, the noise generated during the contact process can be reduced.

[0013] A further feature of this invention is that the upper hinge plate is fixedly connected to the door panel by two bolts, and the lower hinge plate is fixedly connected to the door panel by two bolts.

[0014] By adopting the above technical solution, the upper hinge plate is fixedly connected to the door panel by two bolts, and the lower hinge plate is fixedly connected to the door panel by two bolts, thereby improving the installation stability of the upper and lower hinge plates.

[0024] like Figure 1 and Figure 2 As shown, the guide wheel 3 is made of polyurethane material and is rotatably connected to the end of the first rotating shaft 221 away from the fixed plate 21 via a bearing (not marked in the figure).

[0025] like Figure 1 , Figure 3 and Figure 4 As shown, an intermediate hinge 4 is provided between two adjacent door panels 1. The intermediate hinge 4 includes an upper hinge plate 41 installed on one door panel 1, a lower hinge plate 42 installed on the other door panel 1, and a second pivot 43 disposed between the upper hinge plate 41 and the lower hinge plate 42. Both the upper hinge plate 41 and the lower hinge plate 42 are made of nylon material.

[0026] like Figure 3 and Figure 4As shown, between two adjacent door panels 1, the bottom of the upper door panel 1 is provided with a recessed portion 11, and the top of the upper door panel 1 is provided with a protrusion 12 located within the recessed portion 11. When the two door panels 1 are arranged in parallel, the protrusion 12 is embedded in the recessed portion 11.

The upper hinge plate 41 is integrally provided with a first limiting portion 411 that abuts against the door panel 1, and the lower hinge plate 42 is integrally provided with a second limiting portion 421 that abuts against the door panel 1. When the first limiting portion 411 and the second limiting portion 421 abut against each other, the two door panels 1 are arranged in parallel. At the same time, the upper hinge plate 41 and the door panel 1 are fixedly connected by two bolts, and the lower hinge plate 42 and the door panel 1 are fixedly connected by two bolts (not shown in the figure).

[0027] Example: First, the guide wheel 3 is made of polyurethane material, which has moderate hardness and softness, thereby reducing the noise generated when sliding in the guide rail; second, a nylon sleeve 222 is fitted on the first pivot 221 of the side-mounted hinge assembly 2, which can reduce the noise generated during the rotation of the two fixed plates 21 of the side-mounted hinge assembly 2; at the same time, an intermediate hinge 4 is installed between two adjacent door panels 1, and the upper hinge plate 41 and the lower hinge plate 42 of the intermediate hinge 4 are both made of nylon material, which can also reduce the operating noise; finally, for the door module, the noise reduction design of the intermediate hinge 4 at the connection of adjacent door panels 1, the noise reduction design of the nylon sleeve 222 at the first pivot 221 of the side-mounted hinge assembly 2, and the noise reduction design of the guide wheel 3 using polyurethane material have the effect of reducing the operating noise.

[0028] The upper end of the connecting plate 223 is fixed by a connecting shaft 224 and a connecting nut 225, and further secured with positioning bolts 226, thereby ensuring the structural stability of the connecting plate 223 after installation with the upper fixing plate 21. A groove 11 and a protrusion 12 are provided between the two door panels 1 to improve the tightness of the connection between them. When the first limiting part 411 and the second limiting part 421 abut against each other, the two door panels 1 are arranged in parallel. Since the first limiting part 411 and the second limiting part 421 are integrally formed with the upper hinge piece 41 and the lower hinge piece 42, respectively, and both are made of nylon, noise generated during contact is reduced. The upper hinge piece 41 and the door panel 1 are fixedly connected by two bolts, and the lower hinge piece 42 and the door panel 1 are also fixedly connected by two bolts, thereby improving the installation stability of the upper hinge piece 41 and the lower hinge piece 42.
