Description

Technical Field

[0001] This utility model relates to the field of turbine roller shutter technology, and in particular to an insulated roller shutter door with a noise-reducing turbine drive mechanism. Background Technology

[0002] Turbine high-speed rolling doors, also known as rigid high-speed rolling doors, are a new type of high-speed metal door with anti-theft, wind resistance, heat insulation, and high-temperature isolation features. Compared with traditional rolling door structures, its casing uses a turbine track for guidance, which can significantly improve the opening and closing speed of the rolling door. It is widely used in underground, automobile manufacturing, food, chemical, textile, electronic equipment, supermarket, cold storage, logistics, and warehouse industries.

[0003] Existing turbine high-speed rolling doors have the following drawbacks during use: When using existing turbine high-speed rolling doors, especially after long-term use, the opening and closing process of the door will generate a certain amount of noise. The main source is the collision and running noise between the pulley and the track caused by the lack of lubrication after the pulley at the top of the door enters the turbine track. To address this, we propose an insulated rolling door with a noise-reducing turbine drive mechanism. Utility Model Content

[0004] The main purpose of this utility model is to provide an insulated roller shutter door with a noise-reducing turbine transmission mechanism. By providing an oil replenishment mechanism on the side of the guide rail, the pulley assembly can be lubricated, reducing the noise generated during its operation and effectively solving the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An insulated roller shutter door with a noise-reducing turbine drive mechanism includes a cover, guide rails, and an oil replenishment mechanism. Guide rails are provided on both sides of the bottom of the cover, and a door body inserted between the guide rails is wound inside the cover. An oil replenishment mechanism is provided on the top side of the guide rails. The oil replenishment mechanism includes a turbine track, pulleys, an oil box, a connecting seat, a fixing rod, a spring, and a piston B. Turbine tracks are welded to both ends inside the cover, and pulleys inserted into the turbine tracks are installed on the top side of the door body. An oil box is snapped into the top side of the guide rails, and a connecting seat that penetrates into the guide rails is integrally formed on the surface of the oil box. The fixing rod is located inside the oil box at a position corresponding to the connecting seat, and the piston B is movably connected to the side of the fixing rod by a spring.

[0006] Furthermore, the door body has cavities spaced apart inside, and each cavity is filled with a filling layer made of polyurethane material. The use of polyurethane foam as the filling layer significantly improves the heat insulation and sound insulation characteristics of the roller shutter door when it is closed.

[0007] Furthermore, the side of the cover is provided with a motor cover for installing a power output device, and the power output end of the motor cover is connected to a transmission component located inside the cover; the inside of the motor cover is used to install power components such as motors and reducers to provide power for the opening and closing of the door.

[0008] Furthermore, each of the top sides of the guide rail is provided with a through groove, and the connecting seat is inserted into the through groove corresponding to the position of the through groove. The through groove corresponds to the position of the top pulley when the door is fully opened. After the oil box is installed, the through groove structure allows the connecting seat to pass through the guide rail, and its setting position corresponds to the position where the pulley stops when the door is fully opened, ensuring the oil replenishment of the pulley and the oil discharge end of the connecting seat is closed through the pulley.

[0009] Furthermore, the top and bottom of the oil box are respectively provided with an oil inlet and an oil outlet, and a piston A is inserted into the oil inlet and the oil outlet. Lubricating oil is added to the oil box through the oil inlet and drained through the oil outlet. The opening and closing of the oil inlet and the oil outlet are controlled by the piston A.

[0010] Furthermore, a rubber ring is bonded to the inner wall of the oil box on the side of piston B located inside the oil box; the rubber ring structure adheres to the inner wall of the oil box when piston B is pushed out, thus playing a sealing role.

[0011] Compared with the prior art, this utility model has the following advantages: The bottom of the cover is provided with a guide rail structure. When the door is opened, it rolls up inside the cover and the pulleys at both ends slide into the turbine track. When the door is closed, its ends slide down along the guide rail to close. The oil box is installed on the top of the guide rail and is filled with lubricating oil. Under normal use, piston B closes the connecting seat under the action of the spring, preventing the lubricating oil from being discharged. When the door is fully opened, the position of the pulley will press piston B into the oil box, so that the lubricating oil in the oil box contacts the pulley, and the pulley blocks the oil outlet of the connecting seat, preventing oil leakage. When the door is closed, the oil box can replenish the lubricating oil to the pulley. When the door is rolled up and open, the pulley will slide into the turbine track with lubricating oil. Since replenishing the lubricating oil can be done every time it is closed, sufficient lubrication can be carried out at the connection between the pulley and the turbine track during the movement of the pulley, avoiding the opening and closing noise problem caused by long-term use and reducing operating noise.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figure 1-4 As shown, an insulated roller shutter door with a noise-reducing turbine drive mechanism includes a housing 1, a guide rail 2, and an oil replenishment mechanism 3. The bottom two sides of the housing 1 are provided with guide rails 2, and a door body 201 inserted between the guide rails 2 is wound inside the housing 1. The top side of the guide rail 2 is provided with an oil replenishment mechanism 3. The oil replenishment mechanism 3 includes a turbine track 301, a pulley 302, an oil box 304, a connecting seat 305, a fixing rod 309, a spring 310, and a piston B311. The turbine track 301 is welded to both ends inside the housing 1, and a pulley 302 inserted into the turbine track 301 is installed at the top side of the door body 201. The top side of the guide rail 2 is snapped with an oil box 304, and a connecting seat 305 that penetrates into the guide rail 2 is integrally formed on the surface of the oil box 304. The fixing rod 309 is set inside the oil box 304 at a position corresponding to the connecting seat 305, and the side of the fixing rod 309 is movably connected to the piston B311 through the spring 310.

[0019] The door body 201 has cavities 4 spaced apart inside, and each cavity 4 is filled with a filling layer 401 made of polyurethane. The use of polyurethane foam as the filling layer 401 can significantly improve the heat preservation and sound insulation characteristics of the roller shutter door when it is closed.

[0020] The cover 1 has a motor cover 101 for installing power output devices on its side, and the power output end of the motor cover 101 is connected to the transmission component located inside the cover 1. The top side of the guide rail 2 is provided with through slots 303. The connecting seat 305 corresponds to the position of the through slot 303 and is inserted into the through slot 303. The position of the top pulley 302 of the through slot 303 corresponds to the position of the door 201 when it is fully opened. The motor cover 101 is used to install power components such as motors and reducers to provide power for the opening and closing of the door 201. After the oil box 304 is installed, the through slot 303 structure allows the connecting seat 305 to pass through the guide rail 2. At the same time, its setting position corresponds to the position of the pulley 302 when the door 201 is fully opened, ensuring the oil replenishment of the pulley 302 and the closing of the oil discharge end of the connecting seat 305 through the pulley 302.

[0021] The oil box 304 has an oil inlet 306 and an oil drain 308 at its top and bottom, respectively. A piston A307 is inserted into both the oil inlet 306 and the oil drain 308. A rubber ring 312 is bonded to the inner wall of the oil box 304 on the side of the piston B311 located inside the oil box 304. Lubricating oil is added to the oil box 304 through the oil inlet 306 and drained through the oil drain 308. The piston A307 controls the opening and closing of the oil inlet 306 and the oil drain 308. The rubber ring 312 fits against the inner wall of the oil box 304 when the piston B311 is pushed out, thus providing a sealing function.

[0022] It should be noted that this utility model is an insulated roller shutter door with a noise-reducing turbine transmission mechanism. In use, the bottom of the cover 1 is equipped with a guide rail 2 structure. When the door body 201 is opened, it rolls up inside the cover 1, and the pulleys 302 at both ends slide into the turbine track 301. When the door body 201 is closed, its ends slide down and close along the guide rail 2. The oil box 304 is installed on top of the guide rail 2 and contains lubricating oil. Under normal use, the piston B311 closes the connecting seat 305 under the action of the spring 310, preventing the lubricating oil from draining. When the door body 201 is fully extended, the position of the pulleys 302 will be precisely pressed into the oil box 304. Piston B311 ensures that the lubricating oil inside the oil box 304 contacts the pulley 302, while the pulley 302 blocks the oil outlet of the connecting seat 305 to prevent oil leakage. When the door 201 is closed, the oil box 304 can replenish the lubricating oil to the pulley 302. When the door 201 is rolled up and opened, the pulley 302 will slide into the turbine track 301 with lubricating oil. Since replenishing the lubricating oil can be done every time the door is closed, sufficient lubrication can be achieved at the connection between the pulley 302 and the turbine track 301 during the movement of the pulley, avoiding opening and closing noise problems caused by long-term use and reducing operating noise.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
