Description

Technical Field

[0001] The utility model relates to the technical field of roller shutter door flywheels, in particular to a roller shutter door flywheel device. Background Art

[0002] At present, the roller shutter door flywheel device is used to be installed at both ends of the roller shutter door, and has the function of bearing the weight and rotation of the roller shutter door.

[0003] The traditional roller shutter door flywheel device includes a flywheel disc and a rotating device installed at the center of the flywheel disc. The rotating device is generally composed of a bearing and a rotating shaft. After the roller shutter door is used for a long time, the flywheel disc is easy to omit lubrication, resulting in inconvenience in opening and closing the roller shutter door. Secondly, most existing flywheels are only installed with one flywheel disc, and the stability of the roller shutter rotation of the flywheel device is maintained while the roller shutter rotates, so it lacks certain reliability. Utility Model Content

[0004] The purpose of the utility model is to provide a roller shutter door flywheel device, which solves the technical problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a roller shutter door flywheel device, comprising a mounting plate, a notch is provided on one side surface of the mounting plate, a mounting cylinder is inserted in the notch and threadedly fixed, a flywheel is fixedly connected to one side surface of the mounting cylinder, a bearing is fixedly installed in the flywheel, an inner tube is fixedly installed on the central inner wall of the flywheel, an annular groove is provided around the outer surface of the flywheel near the center, a graphite column for lubricating the bearing is inserted in the annular groove, a clamping frame is fixedly installed on one side surface of the mounting plate near the flywheel, and the graphite column is clamped in the clamping frame;

[0006] The flywheel is located on both side surfaces of the annular groove and is respectively connected to a first gear set and a second gear set. The mounting plate is rotationally connected to a first driven gear and a second driven gear that are correspondingly meshed with the first gear set and the second gear set.

[0007] Optionally, a positioning hole for fixing is formed through a surface of one side of the mounting plate away from the flywheel.

[0008] Optionally, a threaded surface is provided on an outer surface of one end of the mounting tube, and an external thread of the threaded surface is connected to a nut for fixing.

[0009] Optionally, the nut is fitted and fixed on the surface of the mounting plate.

[0010] Optionally, a cap is fixed on the surface of the graphite column.

[0011] Optionally, the card cover limit card is arranged on the card placement rack.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model adopts a graphite column inserted in the flywheel annular groove. First of all, the graphite column is a solid lubricant with the characteristics of strong self-lubricating performance, wear resistance and high temperature resistance. It can not only achieve the lubrication effect on the workpiece, but also will not pollute the workpiece with oil. When the flywheel drives the bearing to rotate the roller shutter outside the inner tube, the graphite column inserted in the annular groove and firmly clamped in the clamping frame will continuously conflict with the bearing and provide lubrication for the bearing. Thus, it not only avoids the phenomenon of the roller shutter flywheel device losing lubricity due to long-term use, but also avoids the tediousness of the user manually replenishing the lubricating oil, thereby improving the lubrication effect of the flywheel device.

[0014] 2. The utility model adopts a first driven gear and a second driven gear on a mounting plate that mesh with the first gear set and the second gear set of the flywheel. When the flywheel rotates the rolling curtain and drives the first gear set and the second gear set to rotate accordingly, the first gear set and the second gear set will also mesh and transmit with the first driven gear and the second driven gear respectively, and the first driven gear and the second driven gear on both sides of the annular groove are respectively meshed and connected in a front-to-back staggered manner, which can provide a stabilizing effect on the rolling curtain rotation of the flywheel, thereby improving the reliable stability of the rolling curtain rotation of the flywheel device.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] For example, see Figures 1 to 4 The utility model provides a technical solution: a roller shutter door flywheel device, comprising a mounting plate 1, a positioning hole 14 for fixing is formed through a surface of one side of the mounting plate 1 away from the flywheel 2, a notch 4 is formed on the surface of one side of the mounting plate 1, a mounting tube 5 is plugged in the notch 4 and is threadedly fixed, a flywheel 2 is fixedly connected to the surface of one side of the mounting tube 5, a bearing 3 is fixedly installed in the flywheel 2, an inner tube 8 is fixedly installed on the central inner wall of the flywheel 2, an annular groove 17 is formed through a circle on the outer surface of the flywheel 2 near the center, a graphite column 16 for lubricating the bearing 3 is plugged in the annular groove 17, a card rack 15 is fixedly installed on the surface of one side of the mounting plate 1 near the flywheel 2, the graphite column 16 is carded in the card rack 15, a card cover 18 is carded on the surface of the graphite column 16, and the card cover 18 is limitedly carded on the card rack 15;

[0022] The flywheel 2 is located at the annular groove 17 and is connected to the first gear set 10 and the second gear set 11 on both sides of the surface. The mounting plate 1 is connected to the first driven gear 12 and the second driven gear 13 which are meshed with the first gear set 10 and the second gear set 11 for upper limit rotation.

[0023] More specifically, in the present embodiment, first, the mounting plate 1 can be positioned and installed through the positioning hole 14, and the graphite column 16 is a solid lubricant with the characteristics of strong self-lubricating performance, wear resistance, and high temperature resistance. It can not only achieve the lubrication effect on the workpiece, but also will not oil the workpiece. When the flywheel 2 drives the bearing 3 to rotate outside the inner tube 8 to roll up the shutter, the graphite column 16 plugged in the annular groove 17, clamped by the card cover 18, and firmly fixed in the card frame 15 will continuously conflict with the bearing 3 and provide lubrication for the bearing 3. At this point, not only the phenomenon of the roller shutter flywheel device losing lubricity due to long-term use is avoided, but also the tediousness of the user manually replenishing the lubricating oil is avoided, thereby improving the lubrication effect of the flywheel device.

[0024] At the same time, when the flywheel 2 rotates the rolling curtain and drives the first gear set 10 and the second gear set 11 to rotate accordingly, the first gear set 10 and the second gear set 11 will also mesh with the first driven gear 12 and the second driven gear 13 respectively. Moreover, on both sides of the annular groove 17, the first driven gear 12 and the second driven gear 13 are meshed and connected in a front-to-back staggered manner, which can provide a stabilizing effect on the rolling curtain rotation of the flywheel 2, thereby improving the reliable stability of the rolling curtain rotation of the flywheel device.

[0025] Furthermore, a threaded surface 6 is formed on the outer surface of one end of the mounting tube 5 , and a nut 7 for fixing is connected to the outer thread of the threaded surface 6 , and the nut 7 is fitted and fixed on the surface of the mounting plate 1 .

[0026] It is worth noting that when installing the flywheel 2 , the installation tube 5 is inserted into the slot 4 and is threadedly connected to the threaded surface 6 using the nut 7 to ensure a stable connection of the flywheel 2 to the installation plate 1 .

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
