Description

Technical Field

[0001] This utility model relates to the field of roller shutter door technology, specifically a guide rail silent roller shutter door machine. Background Technology

[0002] Roller shutters are a common type of door, typically used in industrial, commercial, and some residential settings. Their main characteristic is that they consist of multiple horizontal or vertical panels that can be rolled up or down vertically to form a compact roll, facilitating opening and closing.

[0003] As disclosed in the patent announcement number CN216690912U, a silent roller shutter door motor with guide rails includes a cylinder, a circular plate, side columns, a rotating rod, a roller shutter door, and a noise reduction mechanism. The circular plate is installed on both sides of the cylinder, the side columns are installed at the lower end of the circular plate, and the rotating rod is rotatably installed inside the cylinder. The beneficial effects of this invention, achieved by adopting the above technical solution, are: the device greatly reduces friction between the roller shutter door side and the guide rail, reduces noise, increases the device's lifespan, and facilitates user operation.

[0004] Although the aforementioned patent reduces noise, the roller slides in the guide rail for a long time, and the lubricating oil at the roller shaft dries out, which will still generate noise. However, the aforementioned device does not have a lubrication structure, and simply using rollers for guidance cannot maintain low-noise operation for a long time. Utility Model Content

[0005] The purpose of this utility model is to provide a guide rail silent roller shutter door machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This type of silent roller shutter door motor with guide rails works by having the rollers slide down the inner wall of the guide rail body as the roller body descends. The rollers press against the column head, which is then pushed to one side of the oil tank by the pressure. The plug is then pulled out of the oil inlet through the connecting parts. At this time, the lubricating oil inside the oil tank enters the oil passage through the oil inlet and is sprayed out through the oil nozzle to the lower part of the guide rail body. This lubricates the rollers, making them quieter during use and allowing them to maintain low-noise operation for a long time.

[0017] 2. In this type of guide rail silent roller shutter door motor, in order to avoid damage to the connection between the roller shutter body and the fixing strip due to excessive force when pulling the roller shutter body down, this device has a handle that is movably installed on the front of the fixing strip via a spring. When pulling down the roller shutter body, the handle is held and force is applied downwards, at which time the spring can play a buffering role. Attached Figure Description

[0026] like Figure 1-6 As shown, this utility model provides a technical solution:

[0027] A silent roller shutter door operator with guide rails includes a winding drum 1. Guide rail bodies 2 are provided on both sides of the bottom end of the winding drum 1. A roller shutter body 3 is movably installed inside the two guide rail bodies 2. Rollers 4, which are slidably connected to the guide rail bodies 2, are provided on both sides of the bottom end of the roller shutter body 3. A winding mechanism is provided inside the winding drum 1, including a winding roller 6. The winding roller 6 is movably installed inside the winding drum 1. A motor 7 is provided on one side of the winding drum 1, and the output shaft of the motor 7 is fixedly connected to the winding roller 6. The winding mechanism cooperates with the roller shutter body 3. Oil tanks 5 are provided on both sides of the bottom end of the guide rail bodies 2, and a space is provided between the oil tanks 5 and the interior of the guide rail bodies 2. The lubrication mechanism includes an oil passage 8, which is provided between the oil shell 5 and the guide rail body 2. The oil passage 8 is connected to an oil nozzle 9 on the side of the oil passage 8 near the guide rail body 2. An oil inlet 10 is provided on the lower left side of the oil passage 8. The lubrication mechanism also includes a column groove 11, which is provided inside the guide rail body 2 and near the upper end of the oil passage 8. A column head 13 is movably installed inside the column groove 11. A guide member 14 is provided at the upper end of the column head 13. The guide member 14 is movably connected to the column groove 11 by a spring 15. A connector 16 is vertically provided at the end of the column head 13 away from the guide rail body 2. A plug 17 matching the oil inlet 10 is provided on the front of the connector 16.

[0028] In this embodiment, the motor 7 is started during winding, and the motor 7 drives the winding roller 6 to rotate. After the winding roller 6 rotates, it winds up the roller shutter body 3. During the winding and rising process of the roller shutter body 3, the rollers 4 on both sides of its bottom end will slide upward along the inner wall of the guide rail body 2. When the roller shutter body 3 descends, the rollers 4 will slide downward along the inner wall of the guide rail body 2 until the rollers 4 press the column head 13. After being pressed, the column head 13 is pushed to one side of the oil tank 5 and drives the plug 17 to exit from the oil inlet 10 through the connector 16. At this time, the lubricating oil inside the oil tank 5 enters the oil passage 8 from the oil inlet 10 and is sprayed out from the lower part of the guide rail body 2 through the oil nozzle 9. In this way, the rollers 4 can be lubricated. The lubricated rollers 4 are quieter when in use and can maintain low noise operation for a long time.

[0029] like Figure 4 As shown, a fixing strip 18 is provided at the bottom of the roller shutter body 3. Guide grooves 19 are provided at both ends of the front of the fixing strip 18. Guide rods 20 are vertically arranged inside the guide grooves 19. Guide blocks 21 are movably installed on the outside of the two guide rods 20. A handle 22 is provided between the outer sides of the two guide blocks 21. A spring 12 is provided between the guide grooves 19 and the guide blocks 21 located below the guide rods 20.

[0030] In this embodiment, when the roller blind body 3 is pulled down, in order to avoid damage to the connection between the roller blind body 3 and the fixing strip 18 due to excessive force, the device has a handle 22 movably installed on the front of the fixing strip 18 via a spring 12. When the roller blind body 3 is pulled down, the handle 22 is gripped and downward force is applied. At this time, the spring 12 can serve as a buffer.

[0031] Working principle: When the rollers are rewinding, the motor 7 is started, and the motor 7 drives the take-up roller 6 to rotate. After the take-up roller 6 rotates, it rewinds the roller shutter body 3. During the process of the roller shutter body 3 being rewound and rising, the rollers 4 on both sides of its bottom end will slide upward along the inner wall of the guide rail body 2. When the roller shutter body 3 descends, the rollers 4 will slide downward along the inner wall of the guide rail body 2 until the rollers 4 press the column head 13. After being pressed, the column head 13 is pushed to one side of the oil tank 5 and drives the plug 17 to exit from the oil inlet 10 through the connector 16. At this time, the lubricating oil inside the oil tank 5 enters the oil passage 8 from the oil inlet 10 and is sprayed out from the lower part of the guide rail body 2 through the oil nozzle 9, thus lubricating the rollers 4.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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 preferred examples and are not intended to limit the utility model.
