However, it is apparent to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0027] The applicant believes that the traditional horizontal heating furnace is long, consists of multiple heating wires, and is heavy, so it is easy for the furnace to sink during actual use.

[0028] To this end, the applicant has designed a multi-stage assembled heating wire 1 structure, through which the heating wire 1 in the furnace can be fixed and supported in the horizontal and vertical directions of the operation direction, effectively avoiding the phenomenon of furnace sinking.

[0029] The multi-stage assembled heating wire 1 structure of the present invention mainly comprises two components: a connecting component and a supporting component.

[0030] Among them, the connection component includes a support and fixing block 4 connected to the body of the heating wire 1, having a predetermined operating size and supporting force; and a buckle 5 connected to the support and fixing block 4, having a predetermined operating size and supporting force.

In the later operation process, the limit support part is used to support and limit the heating wire 1 in the longitudinal direction of the operation direction, and at the same time, the perforated rod 201 can be subjected to corresponding limit support operations, so that the limit support part can cooperate with the perforated rod 201 to realize the horizontal and longitudinal limit support of the heating wire 1 in the operation direction, and two-way protection is provided to avoid the phenomenon of furnace sinking.

[0034] The position limiting support part includes two components: a support ring 301 and a position limiting ring 302.

The connecting support unit includes a supporting connecting chain 7 and a steering support shaft 8; the supporting connecting chain 7 has a predetermined working length and supporting force, is connected to the locking adjustment parts, and is in multiple numbers; the steering support shaft 8 has a predetermined working size, and is used for mutual connection between the multiple supporting connecting chains.

In a further preferred embodiment, the limit adjustment plate is a flexible metal plate, which can be a flexible steel plate, and has a predetermined deformation force. In the later operation process, the locking adjustment plate 305 can be adjusted to the predetermined working position first, and then the auxiliary support plate 307 can be wrapped and fixed by the limit plate 202, so that the locking adjustment part can be fixed accordingly as a whole.

The movable connecting block 203 is connected to the perforated rod 201 in a locking position, that is, the movable connecting block 203 is provided with a recessed locking groove adapted to the operating size of the perforated rod 201, so that the movable connecting block 203 can be adjusted accordingly along the working surface of the perforated rod 201.

[0041] In a further preferred embodiment, the operating lengths of the plurality of supporting and fixing blocks 4 are different, so that when the perforating rod 201 performs the perforating and fixing operation, the supporting and fixing block 4 with a longer operating length can perform a secondary perforating and fixing support operation, and the operating state is Figure 2 At the same time, after completing the corresponding assembly work, the corresponding supporting long plates can be welded outside the plurality of supporting components, and the plurality of supporting components can be further supported and limited, and the plurality of supporting long plates can be multiple, and a predetermined working distance is left between the plurality of supporting long plates, and the number of the supporting long plates can be flexibly adjusted according to the specific size of the heating furnace.

[0042] The assembly sequence and method of the heating wire 1 structure of the present invention are as follows:

[0043] The support and fixing block 4 is provided with a corresponding groove for carrying and limiting the body of the heating wire 1. First, the heating wire 1 is placed in the groove provided in the support and fixing block 4, and the multiple support and fixing blocks 4 are mutually fixed and limited by the buckle 5. Then, the perforated rod 201 is passed through the slot 6 provided in the support and fixing block 4 and the position of the buckle 5, and the perforated rod 201 is simultaneously superimposed on the outer surface of the working surface of the support and fixing block 4, and the two perforated rods 201 can be connected and fixed by welding. Then, the locking support unit 3 is sleeved on the outside of the heating wire 1, and after adjusting to the predetermined working position, the locking adjustment roller 306 is rotated clockwise, so that the locking adjustment plate 305 moves in the direction close to the heating wire 1, driving the auxiliary support plate 307 to move and adjust as a whole synchronously. After the movement is adjusted to the predetermined working position, the rotation of the locking adjustment roller 306 is stopped, and then the movable connecting block 203 is slidably adjusted along the working surface of the perforated rod 201. The movable connecting block 203 and the auxiliary support plate 307 are staggered. When the movable connecting block 203 drives the limit plate 202 to move to the predetermined working position, the limit plate 202 is bent so that the limit plate 202 wraps the nearby auxiliary support plate 307, and then the locking adjustment roller 306 is rotated clockwise again to compact the limit plate 202, and then the limit plate 202 is further bent, so that the locking support unit 3 can be limited and fixed as a whole. Finally, the above steps are repeated in sequence to limit and fix multiple locking support units 3 to the corresponding working positions, and the assembly of the heating wire 1 structure is completed.
