[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-5 As shown, an industrial furnace roller structure includes an outer roller body 1, on which a plurality of sliding grooves 200 arranged in a circumferential array are formed. An inner roller body 19 is slidably mounted inside the outer roller body 1. A plurality of extension blocks 20 arranged in a circumferential array are provided on the inner roller body 19. A plurality of slots 21 arranged in a circumferential array are formed on the outer roller body 1. Side plates 23 are symmetrically arranged in the slots 21. Extension plates 24 are provided on the side plates 23. Fixed grooves 201 are formed on the extension blocks 20. Connecting grooves 202 are symmetrically formed on both sides of the sliding grooves 200. The extension plates 24 slide in the connecting grooves 202.

[0024] Specifically, in use, the inner roller body 19 is inserted into the outer roller body 1, and then the multiple extension blocks 20 on the inner roller body 19 slide in the sliding groove 200. Then, the extension plates 24 on the two side plates 23 in the slot 21 enter the connecting groove 202 and are then inserted into the fixing groove 201 on the extension block 20, thus fixing the inner roller body 19 into the outer roller body 1.

[0025] In the above scheme, by setting an inner roller body 19 inside the outer roller body 1, it is possible to replace only the damaged outer roller body when replacing the roller body. This is achieved by multiple extension blocks 20 on the inner roller body 19 and sliding grooves 200 opened on the outer roller body 1. The inner roller body 19 is fixed inside the outer roller body 1 by multiple slots 21 on the outer roller body 1 and side plates 23 inside the slots 21. The inner roller body 19 is fixed inside the outer roller body 1 by connecting grooves 202, which allows extension plates 24 to be inserted into fixing grooves 201, further fixing the inner roller body 19 inside the outer roller body 1.

[0026] As a further embodiment provided by this utility model, according to Figure 1 and Figure 2 As shown, the extension plate 24 is provided with a plurality of elastic elements 25 arranged in a linear array, and the elastic elements 25 are fixedly disposed on the inner wall of the sliding groove 200.

[0027] Furthermore, a plug rod 22 is slidably disposed within the slot 21, the plug rod 22 being inserted into the slot 21 and located between the two side plates 23.

[0028] Specifically, after the inner roller body 19 is inserted into the outer roller body 1, the insertion rod 22 moves synchronously with the inner roller body 19. When the insertion rod 22 is inserted into the slot 21, the insertion rod 22 will push the two side plates 23 to move to both sides, and the elastic element 25 will be subjected to force.

[0029] As a further embodiment provided by this utility model, according to Figure 2 As shown, a connecting gear 17 is provided on the insertion rod 22, and multiple connecting tooth blocks 18 arranged in a circular array are provided on the connecting gear 17.

[0030] Furthermore, it includes an inner roller body 19, on which a gear disk 14 is rotatably disposed, and on which a plurality of gear blocks 15 are arranged in a circumferential array, and the gear blocks 15 are coupled to the connecting tooth blocks 18.

[0031] Furthermore, the outer roller body 1 has a first housing 11 and a second housing 13 at its two ends, and a connecting shaft 12 is provided on the first housing 11.

[0032] Specifically, during unlocking, rotating the connecting shaft 12 drives the gear disk 14 to rotate. Then, the gear block 15 on the gear disk 14 will push the connecting gear 17 to rotate through the connecting tooth block 18. The connecting gear 17 will drive the insertion rod 22 to rotate and cause the side of the side plate 23 to swing upward. At this time, the side plate 23 stops pushing, and the elastic element 25 releases the force and unlocks the inner roller 19 from the outer roller 1.

[0033] Working principle: In use, the inner roller body 19 is inserted into the outer roller body 1. After the inner roller body 19 is inserted into the outer roller body 1, the insertion rod 22 moves synchronously with the inner roller body 19. When the insertion rod 22 is inserted into the slot 21, the insertion rod 22 pushes the two side plates 23 to move to both sides. At the same time, the elastic element 25 is subjected to force, and then the multiple extension blocks 20 on the inner roller body 19 slide in the sliding groove 200. Then, the extension plates 24 on the two side plates 23 in the slot 21 enter the connecting groove 202 and are inserted into the fixing groove 201 on the extension block 20, thus moving the inner roller body 19 into the slot 200. The inner roller 19 is fixed inside the outer roller body 1. When unlocking, the connecting shaft 12 is rotated to drive the gear disk 14 to rotate. Then, the gear block 15 on the gear disk 14 will push the connecting gear 17 to rotate through the connecting tooth block 18. The connecting gear 17 will drive the insert rod 22 to rotate and cause the side of the side plate 23 to swing upward. At this time, the side plate 23 stops pushing. At this time, the elastic element 25 releases the force and pushes the side plate 23 outward. At this time, the extension plate 24 moves out of the fixing groove 201 and unlocks the inner roller body 19 from the outer roller body 1. Then, the inner roller body 19 is pulled out from the outer roller body 1.

[0034] The rotating connection mentioned above is a shaft connection, and the fixed connection is welding.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
