DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0020] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A structural schematic diagram of a preferred embodiment of a special heating tube for a composite material high-temperature oven provided by the utility model; Figure 2 for Figure 1 A schematic diagram of the structure of the extension block shown; Figure 3 for Figure 1 An enlarged schematic diagram of part A is shown; Figure 4 for Figure 1 The top view of the terminal is shown. A heating tube for a composite material high temperature oven comprises: a heating tube 1, two connecting tubes 2 are fixedly connected to the surface of the heating tube 1, a terminal 3 is arranged on the connecting tube 2, the terminal 3 comprises a conical block 4, four clamping blocks 5 are fixedly connected to the top of the conical block 4, a clamping groove 6 is provided between the four clamping blocks 5, a contact hole 7 is provided inside the conical block 4, a rubber pad 8 is fixedly connected to the clamping block 5, a clamping ring 9 is threadedly connected to the surface of the conical block 4, and an anti-sliding block 10 is fixedly connected to the outer surface of the clamping ring 9. The terminal 3 of the heating tube 1 is simply and tightly connected, and no complicated wiring operation is required, which greatly saves installation time. The work efficiency is significantly improved. Since there is no need for complicated wiring, the operator does not need to have excessive professional skills and rich experience, which reduces the technical requirements for the operator. This not only reduces circuit failures caused by wiring errors, but also avoids safety accidents caused by improper operation.

[0021] The heating tube 1 is fixedly connected with threaded rods 11 on both sides, and a threaded tube 12 is threadedly connected to the threaded rod 11. A threaded groove 13 is provided on the threaded tube 12, and a cushion 14 is fixedly connected to the threaded tube 12. An extension block 15 is arranged in the threaded groove 13, and the extension block 15 includes an extension support block 16, and an extension threaded rod 17 is fixedly connected to the extension support block 16, and an extension cushion 18 is fixedly connected to the extension support block 16. An extension threaded groove 19 is provided on the extension support block 16. After the wiring is completed, the threaded tubes 12 on both sides can be rotated, and the threaded tubes 12 can be supported on the inner wall of the oven after being extended to fix the heating tube 1. If the threaded tube 12 is not long enough, an extension block 15 can be added. The extension threaded rod 17 on the extension block 15 can be fixed in the threaded groove 13 by threaded connection, and the extension block 15 can be continued to be added through the extension threaded groove 19, so as to avoid the situation that the heating tube 1 is insufficient in length due to ovens of different models, so that the installation and disassembly of the heating tube 1 is simpler.

[0022] The heating tube 1 is provided with a middle rod 20 , and the inner surface of the middle rod 20 is provided with a reflective layer 22 . The middle rod 20 will bear the supporting force when the heating tube 1 is installed, so as to ensure that the heating tube 1 is installed sufficiently firmly.

[0023] A heating wire 21 is fixedly connected inside the heating tube 1, and the heating wire 21 is electrically connected to the contact hole 7. The heating wire 21 [nickel-chromium alloy wire] can generate heat after being energized and is evenly distributed in the heating tube body to ensure uniform heating.

[0024] The material of the reflective layer 22 is aluminum foil, the material of the rubber pad 8 is rubber, the clamping block 5 is elastic, and the reflective layer 22 is located on the inner wall of the heating tube to reflect heat and improve the utilization rate of heat.

[0025] Insulation layers 23 are provided on both sides of the heating tube 1, and indicator lights 24 are installed at both ends of the heating tube 1. The insulation layer 23 prevents heat from being transferred to a direction where heating is not required, thereby improving energy utilization efficiency. The indicator light 24 is electrically connected to the contact hole 7 to display the working status of the heating tube, so that it can be observed whether the heating tube 1 is successfully powered on.

[0026] The working principle of a special heating tube for composite material high temperature oven provided by the utility model is as follows:

[0027] The traditional heating tube 1 needs to be fixed in the oven and wired to make it energized and generate heat, and then a circulating fan is used to circulate the heat of the heating tube 1 in the oven to dry the composite material. The wiring is usually complicated. The heating tube 1 only needs to insert two live wires into the contact holes 7 on the terminal ends 3 on both sides, and then rotate the clamping ring 9. Since the conical block 4 is narrow at the top and wide at the bottom, and the clamping block 5 is elastic, after rotating the clamping ring 9, the clamping ring 9 moves up to clamp the clamping block 5 inward, and the rubber pad 8 begins to clamp the insulating layer of the live wire, tightens the live wire, and completes the wiring. The operation is simple. It only needs to insert the live end of the live wire into the contact hole 7 and then rotate the clamping ring 9, which significantly improves work efficiency. Since there is no need for complicated wiring, the operator does not need to have excessively high professional skills and rich experience, which reduces the technical requirements for the operator.

[0028] Compared with the related art, the special heating tube for composite material high temperature oven provided by the utility model has the following beneficial effects:

[0029] The wiring of the terminal 3 of the heating tube 1 is simple and tight, and no complicated wiring operation is required, which greatly saves installation time. The work efficiency is significantly improved. Since there is no need for complicated wiring, the operator does not need to have excessive professional skills and rich experience, which reduces the technical requirements for the operator. This not only reduces circuit failures caused by wiring errors, but also avoids safety accidents caused by improper operation; at the same time, the simplicity of installation and disassembly also enables maintenance work to be carried out quickly, reducing equipment downtime and ensuring production continuity.
