[0025] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments. It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.

[0026] As Figure 1-2 shown, an installation structure of a wire-hanging steel nail 5 for a heating furnace includes a heat-insulating brick 1, a slider 4, and an insulator. A chute 2 is provided on one side of the heat-insulating brick 1, which can extend longitudinally or vertically, and both ends of the chute 2 extend to the side wall of the heat-insulating brick 1.

[0027] An installation hole is provided in the middle of the chute 2 of the heat-insulating brick 1. The installation hole is preferably a threaded hole, so that the wire-hanging steel nail 5 is threadedly connected to the installation hole. One end of the wire-hanging steel nail 5 extending into the installation hole is provided with an external thread, which can increase the friction and reduce the risk of insecure fixation. Due to the material limitation of the heat-insulating brick 1, the internal thread of the installation hole is likely to be damaged or inaccurately formed. The slider 4 is slidably assembled in the chute 2. The wire-hanging steel nail 5 passes through the slider 4 and then extends into the heat-insulating brick 1 and is threadedly connected to the slider 4. The slider 4 can be a heat-resistant metal, so that the axial position of the wire-hanging steel nail 5 can be limited by the threaded structure to ensure stability.

[0028] The insulator is arranged at the end of the wire-hanging steel nail 5 for the electric heating wire 9 to be wound around. The insulator is made of heat-resistant material, and the electric heating wire 9 can be wound according to actual requirements.

[0029] In an alternative embodiment, the chute 2 is a dovetail groove. Correspondingly, the slider 4 is a dovetail-shaped slider 4 with a cross-section adapted to the chute 2, so that the slider 4 can only slide along the chute 2, and thus the stability of the wire-hanging steel nail 5 is ensured in all directions under the limitation of the wire-hanging steel nail 5 and the installation hole.

[0030] In an alternative embodiment, one end of the chute 2 is provided with an installation notch 3 corresponding to the slider 4, so that the slider 4 can be installed according to the actual situation after the heat-insulating brick 1 is laid.

[0031] In this embodiment, the slider 4 is a heat-resistant metal block, so that the internal hole thread has high stability. A screw hole corresponding to the wire-hanging steel nail 5 is provided in the middle of the slider 4, which can effectively limit the wire-hanging steel nail 5. After the wire-hanging steel nail 5 is threadedly assembled to the slider 4, it extends into the insulating brick 1. The installation hole of the insulating brick 1 can be opened after the insulating brick 1 is laid, knowing the position.

[0032] In an alternative embodiment, the insulator includes a base sleeve 6 and an upper cover 7. The base sleeve 6 can be a high-temperature resistant porcelain sleeve. The base sleeve 6 is sleeved on the wire-hanging steel nail 5, so that the electric heating wire 9 can be insulated from the wire-hanging steel nail 5. A baffle is provided on one side of the base sleeve 6 close to the insulating brick 1. A groove for installing the electric heating wire 9 is formed between the baffle and the upper cover 7, thereby ensuring the stability of the electric heating wire 9. Further, the upper cover 7 is a high-temperature resistant porcelain sleeve. The upper cover 7 is in a cover shape, and a through hole corresponding to the wire-hanging steel nail 5 is provided in the middle. The diameter difference between the inner diameter of the upper cover 7 and the outer diameter of the base sleeve 6 is greater than the diameter of the electric heating wire 9, for accommodating the electric heating wire 9. A limiting notch corresponding to the electric heating wire 9 is provided on one side of the upper cover 7 close to the baffle. After the upper cover 7 is covered, the relative position of the electric heating wire 9 is limited by the limiting notch, ensuring the stability after the electric heating wire 9 is wound.

[0033] Further, the wire-hanging steel nail 5 is provided with a stepped platform for blocking the base sleeve 6, so as to block the base sleeve 6 and limit the position of the base sleeve 6. A stopper is provided at one end of the wire-hanging steel nail 5 away from the insulating brick 1. By the limitation of the stopper, the distance between the end of the upper cover 7 and the baffle is less than the diameter of the electric heating wire 9, so as to avoid the wire-hanging steel nail 5 detaching from the insulator on the premise that the electric heating wire 9 is limited by the limiting notch.

[0034] Further, the wire-hanging steel nail 5 has a multi-faceted portion 501 corresponding to the central hole of the upper cover 7. The central hole of the upper cover 7 is a multi-faceted structure, so as to limit the rotation angle of the upper cover 7. In this embodiment, there are multiple limiting notches, such as 4 - 8, so as to meet the extension of the electric heating wire 9 at multiple angles. The multiple limiting notches are evenly distributed in the circumferential direction of the upper cover 7.

[0035] In this embodiment, one end of the wire-hanging steel nail 5 corresponding to the stopper is a tail post 502 with a cylindrical structure, and its diameter is smaller than the inscribed circle of the multi-faceted structure, so as to form a stepped structure for sequentially installing the base sleeve 6, the upper cover 7 and the stopper.

[0036] The stopper is a limit pin or a nut 8. Correspondingly, the wire-hanging steel nail 5 is provided with external threads except for the multi-faceted portion 501, so as to be threadedly connected to the insulating brick 1 and the slider 4, and the tail post 502 is threadedly connected to the nut 8.

[0037] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model are within the protection scope of the pending claims of the present utility model.
