Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 , in order to solve the problem that for the existing heating furnace rollers, in order to ensure the stability of the work, multiple bolts are required to fix between the rollers and the bearing seats, which results in very cumbersome installation and disassembly operations for the furnace rollers, long time consumption, and insufficient practicability, the following preferred technical solutions are provided:

[0023] A heating furnace roller includes an outer roller body 1 and an inner roller body 2 rotatably connected to the inner wall of the outer roller body 1. Bearing assemblies 3 are arranged on both sides of the inner roller body 2. The bearing assembly 3 includes a connecting frame 31 for connecting the inner wall of the furnace. One end of the connecting frame 31 is fixedly connected to a bearing body 32. A connecting port 33 is opened on one side of the bearing body 32. A clamping ring 34 is fixedly installed on the inner wall of the connecting port 33. A threaded hole 4 is opened on the upper wall of the inner roller body 2. Threads are provided on the inner wall of the threaded hole 4. A fixing assembly 5 is arranged on the upper wall of the bearing body 32. The fixing assembly 5 is inserted into the threaded hole 4 for connecting the inner roller body 2 and the bearing body 32. The clamping ring 34 is a component made of rubber material, and the inside of the clamping ring 34 is a hollow structure. When one side of the inner roller body 2 is completely located inside the inner wall of the connecting port 33, the fixing assembly 5 and the threaded hole 4 are on the same vertical line.

[0024] The fixing component 5 includes a bolt body 51 threadedly connected to the inner wall of the threaded hole 4. A control member 52 is rotatably connected to the upper wall of the bolt body 51. A threaded rod 53 is fixedly connected to the lower end of the control member 52. A top block 54 is sleeved on the outer wall of the threaded rod 53. The top block 54 is slidably connected to the inner wall of the bolt body 51, and both sides of the top block 54 are in contact with the inner wall of the bolt body 51. Openings 55 are formed on both sides of the bolt body 51. The openings 55 communicate with the inner cavity of the bolt body 51. A reinforcing block 56 is slidably arranged on the inner wall of the opening 55. The threaded rod 53 penetrates through the upper wall of the bolt body 51 and is rotatably connected to the inner wall of the bolt body 51. An elastic band is fixedly connected between the reinforcing block 56 and the inner wall of the opening 55 for pulling back the pushed-out reinforcing block 56. When the elastic band is in a tensioned state, one end of the reinforcing block 56 protrudes from the opening 55, and the other end is flush with the opening 55.

[0025] Specifically, during installation, only need to insert the inner roller body 2 into the connection port 33. When one side of the inner roller body 2 is completely inside the inner wall of the connection port 33, at this time, the fixing component 5 and the threaded hole 4 are on the same vertical line. Use the fixing component 5 to threadedly connect the threaded hole 4, and clamp the inner roller body 2 through the clamping ring 34 for reinforcement connection. After the fixing component 5 is connected to the threaded hole 4, rotate the control member 52, drive the threaded rod 53 to rotate by using the control member 52, thereby driving the top block 54 to move on the inner wall of the bolt body 51. When the top block 54 moves to one side of the opening 55, the reinforcing block 56 will be pushed out of the opening 55, so that the reinforcing block 56 is close to the inner wall of the threaded hole 4, making the installation extremely firm. For disassembly, only need to remove the fixing component 5. The operation is convenient, solving the problem that for the existing furnace rolls of heating furnaces, in order to ensure the stability of work, between the rolls and the bearing seats need to be fixed by multiple bolts, so the installation and disassembly operations of the furnace rolls are very cumbersome, time-consuming, and lack of practicality.

[0026] Working principle: Insert the inner roller body 2 into the connection port 33. When one side of the inner roller body 2 is completely inside the inner wall of the connection port 33, at this time, the fixing component 5 and the threaded hole 4 are on the same vertical line. Use the fixing component 5 to threadedly connect the threaded hole 4, and clamp the inner roller body 2 through the clamping ring 34 for reinforcement connection. After the fixing component 5 is connected to the threaded hole 4, rotate the control member 52, drive the threaded rod 53 to rotate by using the control member 52, thereby driving the top block 54 to move on the inner wall of the bolt body 51. When the top block 54 moves to one side of the opening 55, the reinforcing block 56 will be pushed out of the opening 55, so that the reinforcing block 56 is close to the inner wall of the threaded hole 4, making the installation extremely firm. For disassembly, only need to remove the fixing component 5.
