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.

[0022] See also Figure 1-3 A combined hollow bearing roller in this embodiment includes a bearing body 1 and a roller body 2, a split component is installed on the bearing body 1, and a fixed component is installed on the bearing body 1.

[0023] The split assembly includes a turntable 3 plugged into the outer side of the roller body 2, two vertical plates 4 are fixedly installed inside the turntable 3, and a mounting groove is opened inside the turntable 3, and the vertical plates 4 are fixedly connected to the turntable 3 through the mounting groove.

[0024] Telescopic springs 5 ​​are fixedly installed on the opposite sides of the two vertical plates 4, and movable plates 6 are fixedly installed on the opposite sides of the two telescopic springs 5. A sliding groove is opened inside the turntable 3, and the movable plate 6 is movably connected to the turntable 3 through the sliding groove, providing guidance for the movement of the movable plate 6, making the movement of the connecting rod 7 more convenient.

[0025] A plug-in rod 7 is fixedly installed on the opposite side of the two movable plates 6, and plug-in holes are opened on both sides of the roller body 2. The plug-in rod 7 is plugged into the roller body 2 through the plug-in holes to fix the turntable 3 on the outside of the roller body 2, thereby facilitating the installation of the sealing ring 11.

[0026] A rope 8 is fixedly installed on the opposite side of the two movable plates 6. A first through hole is opened inside the vertical plate 4, and the rope 8 extends to the outside of the vertical plate 4 through the first through hole. A second through hole is opened inside the turntable 3, and the rope 8 extends to the outside of the turntable 3 through the second through hole. Connecting plates 9 are fixedly installed on the tops of the two ropes 8, so that the user can pull the rope 8 through the connecting plate 9.

[0027] It should be noted that by installing the disassembly assembly, the sealing ring 11 on the outside of the bearing roller body 2 can be disassembled and replaced when the internal sealing ring 11 is worn, thereby reducing the external dust from entering the bearing and corroding the roller body 2, which is beneficial to increasing the service life of the roller body 2.

[0028] Specifically, when the sealing ring 11 of the combined hollow bearing roller needs to be replaced, the connecting plate 9 is pulled to drive the rope 8 to move on the guide rod 10, and the movable plate 6 is simultaneously driven to move, so that the telescopic spring 5 is compressed, and then the plug-in rod 7 is driven to move to one side to release the connection with the roller body 2. Then the turntable 3 is removed from between the bearing body 1 and the roller body 2, the sealing ring 11 is removed from the turntable 3, and a new sealing ring 11 is replaced and attached to the turntable 3, so as to reduce the situation where external dust enters the bearing and wears the roller body 2, which is beneficial to improve the service life of the roller body 2.

[0029] The fixing assembly includes a sealing ring 11 adhered to the turntable 3, an extension hole 12 is opened on the top of the roller body 2, and a discharge hole 13 is opened on the outside of the roller body 2. The number of the extension hole 12 and the discharge hole 13 are both several, and two guide rods 10 are rotatably installed inside the turntable 3.

[0030] It should be noted that, by installing the fixing assembly, it is convenient to replace the sealing ring 11 outside the roller body 2 , thereby improving the replacement efficiency and the use effect of the bearing roller body 2 .

[0031] Specifically, when the combined hollow bearing roller is in use, lubricating oil is poured into the extension hole 12, and then flows out of the roller body 2 through the discharge hole 13 opened on the outside of the roller body 2, lubricating the connection between the bearing body 1 and the roller body 2, so that the friction of the roller body 2 is reduced when it rotates, thereby increasing the service life of the roller body 2.

[0032] The working principle of the above embodiment is:

[0033] (1) When the sealing ring 11 of the combined hollow bearing roller needs to be replaced, the connecting plate 9 is pulled to drive the rope 8 to move on the guide rod 10, and the moving plate 6 is simultaneously driven to move, so that the telescopic spring 5 is compressed, and then the plug-in rod 7 is driven to move to one side to release the plug-in with the roller body 2. Then, the turntable 3 is removed from between the bearing body 1 and the roller body 2, and the sealing ring 11 is removed from the turntable 3. A new sealing ring 11 is replaced and attached to the turntable 3, so as to reduce the external dust from entering the bearing and corroding the roller body 2, which is beneficial to prolonging the service life of the roller body 2.

[0034] (2) When the combined hollow bearing roller is in use, lubricating oil is poured into the extension hole 12, and then flows out of the roller body 2 through the discharge hole 13 opened on the outside of the roller body 2, thereby lubricating the connection between the bearing body 1 and the roller body 2, thereby reducing friction when the roller body 2 rotates and increasing the service life of the roller body 2.
