[0001] This utility model relates to the field of electric heating tube technology, specifically to a utility model of a high-power electric heating tube. Background Technology
[0002] High-power electric heating tubes are widely used in industrial production and daily life, including chemical reactor heating, food processing, and heating systems. As application scenarios continue to expand, the performance requirements for electric heating tubes are increasing, especially in terms of protection.
[0003] During the transportation, installation and daily use of electric heating tubes, they inevitably encounter collisions and impacts, which seriously threaten their performance and service life. The main structure of electric heating tubes is usually quite fragile, and the tube body is mostly made of thin-walled metal material. When subjected to slight impacts, they are prone to dents and deformations, causing the internal heating wire to shift or even break, thereby affecting the heating effect and even causing short circuit failures. Utility Model Content
[0004] In view of the problems existing in the high-power electric heating tubes of the above-mentioned utility models, this utility model is proposed.
[0005] Therefore, the purpose of this utility model is to provide a utility model of a high-power electric heating tube, which solves the problem that the main structure of electric heating tubes is usually relatively fragile, and the tube body is mostly made of thin-walled metal material, which is prone to dent and deformation when subjected to slight impact, resulting in displacement or even breakage of the internal heating wire, thereby affecting the heating effect and even causing short circuit faults.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A utility model of a high-power electric heating tube includes a base. The upper surface of the base has a mounting hole, and the high-power electric heating tube body is fixedly connected inside the mounting hole. The lower surface of the base has two insertion holes, each containing a plug. One side of each insertion hole has a sliding groove, and a fixing mechanism is provided inside the two sliding grooves. The two plugs are fixed by corresponding fixing mechanisms. The lower ends of the two plugs are fixedly connected to a mounting plate. A U-shaped protective rod is fixedly connected to the lower surface of the mounting plate, and multiple annular protective rings are fitted onto the outer surface of the U-shaped protective rod.
[0008] Preferably, the fixing mechanism includes two lead screws, two fixing blocks, and two knobs. The two lead screws are rotatably connected to the inside of the corresponding slide grooves, and the two fixing blocks are threaded onto the rod walls of the corresponding lead screws. One end of each of the two lead screws passes through one side of the corresponding slide groove and is fixedly connected to the corresponding knob.
[0009] Preferably, the interiors of the two grooves are symmetrically provided with limiting grooves, and each limiting groove is slidably provided with a limiting block inside, and each limiting block is fixedly connected to the outer surface of the corresponding fixed block.
[0010] Preferably, each of the two inserts has a fixing hole on one side, and the two fixing holes are respectively fixedly connected to the corresponding fixing block.
[0011] Preferably, the base has circular grooves on both sides, and the two circular grooves are respectively matched with the corresponding knobs.
[0012] Preferably, a hexagonal groove is provided on one side of each of the two knobs.
[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0014] 1. This utility model, by wrapping a U-shaped protective rod around the heating tube body, can absorb the impact force through structural deformation when it is hit. Multiple outer ring protective rings further buffer the vibration and disperse the impact force, forming a multi-layer protection system. This effectively reduces problems such as denting and deformation of the heating tube body, displacement or breakage of the internal heating wire caused by collision, ensures stable heating effect, and reduces the risk of short circuit.
[0015] 2. This utility model, through the cooperation of a knob, a lead screw and a fixing block, allows the fixing block to be inserted into the fixing hole of the insert by rotating the knob, thereby realizing the quick fixing and disassembly of the mounting plate and the U-shaped protective rod. The design of the limiting block and the limiting groove prevents the fixing block from rotating, ensuring stable and reliable installation. At the same time, the circular groove can prevent accidental operation of the knob, and the hexagonal groove facilitates the use of tools, improving installation efficiency and convenience.

[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] This utility model embodiment discloses a utility model of a high-power electric heating tube.
[0024] This utility model provides, for example Figure 1-3 The utility model of a high-power electric heating tube includes a base 1. The upper surface of the base 1 has a mounting hole, and the high-power electric heating tube body 2 is fixedly connected inside the mounting hole. The lower surface of the base 1 has two insertion holes, and each insertion hole has a plug 3 inserted into it. Each side of the two insertion holes has a sliding groove, and a fixing mechanism is set inside the two sliding grooves. The two plugs 3 are fixed by their respective fixing mechanisms. The lower ends of the two plugs 3 are fixedly connected to a mounting plate 4. The lower surface of the mounting plate 4 is fixedly connected to a U-shaped protective rod 5, and the outer surface of the U-shaped protective rod 5 is fitted with multiple annular protective rings 6.
[0025] The U-shaped protective rod 5 is fixed to the lower surface of the mounting plate 4 and surrounds the heating tube body 2. When the heating tube is subjected to a side impact, the U-shaped protective rod 5 first contacts the impactor and absorbs part of the impact force through its own structural deformation, reducing the impact force directly acting on the heating tube body 2. Multiple annular protective rings 6 are fitted onto the outer surface of the U-shaped protective rod 5, forming a multi-layered protection. The annular protective rings 6 can be made of elastic material to further buffer vibration during the collision, prevent excessive deformation of the U-shaped protective rod 5, and disperse the impact force to avoid excessive local stress that could cause deformation of the heating tube body 2.
[0026] To secure mounting plate 4, such as Figure 1-2 As shown, the fixing mechanism includes two lead screws 7, two fixing blocks 8, and two knobs 9. The two lead screws 7 are rotatably connected to the inside of the corresponding slide grooves. The two fixing blocks 8 are threaded onto the rod walls of the corresponding lead screws 7. One end of each lead screw 7 passes through one side of the corresponding slide groove and is fixedly connected to the corresponding knob 9. Each of the two inserts 3 has a fixing hole on one side, and the two fixing holes are fixedly connected to the corresponding fixing blocks 8.
[0027] During the installation of the fixing mechanism, the base 1 is first divided into upper and lower parts. Then, corresponding placement grooves are cut on the side of the two parts that are close to each other. Then, the fixing block 8, knob 9 and screw rod 7 can be installed to facilitate the installation. Finally, the upper and lower parts are welded or glued together to complete the installation of the entire fixing mechanism. When the fixing mechanism is in use, the insert 3 is first inserted into the insertion hole on the lower surface of the base 1 to initially position the mounting plate 4 and U-shaped guard rod 5. At this time, the fixing hole on one side of the insert 3 is aligned with the fixing block 8 in the slide groove. Then, the knob 9 is turned. The knob 9 drives the screw rod 7 to rotate in the slide groove. Since the fixing block 8 is threaded onto the screw rod 7, the rotation of the screw rod 7 causes the fixing block 8 to move axially along the screw rod 7 and insert into the fixing hole of the insert 3, locking the insert 3 on the base 1, thereby fixing the mounting plate 4.
[0028] To prevent the fixed block 8 from rotating, such as Figure 1-2 As shown, the interiors of the two slides are symmetrically provided with limiting grooves, and each limiting groove is slidably provided with a limiting block 10. Each limiting block 10 is fixedly connected to the outer surface of the corresponding fixed block 8.
[0029] The limiting block 10 in the slide groove is fixedly connected to the fixing block 8 and slides in the limiting groove to restrict the movement direction of the fixing block 8, prevent it from rotating, ensure that the fixing block 8 is accurately inserted into the fixing hole, and improve the installation stability.
[0030] To prevent accidental activation of knob 9, such as Figure 1-2 As shown, circular grooves are provided on both sides of the base 1, and the two circular grooves are matched with the corresponding knobs 9. A hexagonal groove is provided on one side of each of the two knobs 9.
[0031] The knob 9 is placed inside the circular groove to prevent it from turning accidentally during daily use. At the same time, the hexagonal groove makes it convenient for staff to turn the knob 9 with an Allen wrench.
[0032] 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.
