[0002] An electric heating tube is an electrical component that specifically converts electrical energy into heat energy. It uses a metal tube as the outer shell (including stainless steel and copper tubes), and spiral electric heating alloy wires (nickel-chromium and iron-chromium alloys) are evenly distributed along the central axis inside the tube. Its gap is filled and compacted with magnesia sand having good insulation and heat conduction performance, and both ends of the tube orifice are sealed with silica gel. This metal-sheathed electric heating element can heat air, metal molds, and various liquids. A bundled electric heating tube is an electric heating tube formed by bundling multiple electric heating tubes. The bundled electric heating tube is cheap, easy to use, easy to install, and pollution-free, and is widely used in various heating occasions.

The heat insulation box body is located inside the installation groove. Bending grooves are opened on the right sides of the front and rear ends of the heat insulation box body. A first return spring and a bending clamping block are installed in each of the two bending grooves. A temperature display instrument, a warning lamp bead, and a micro buzzer are installed at the right end inside the heat insulation box body. Two second return springs are installed at the left end inside the heat insulation box body, and the other ends of the two second return springs are connected to a glass fiber heat insulation sheet, and a temperature detection head is installed through the glass fiber heat insulation sheet.

[0006] Furthermore, the lower right side of the bundled electric heating tube main body passes through the contact groove.

[0007] Further, a heat insulation cover is horizontally installed at the upper end of the heat insulation box body.

[0008] Further, the movable ends of the two first return springs respectively abut against the two bent clamping blocks, and the two bent clamping blocks are respectively clamped in the two side clamping grooves.

Detailed Embodiments

[0017] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please refer to Figures 1-3 , the present utility model provides a technical solution: a bundled explosion-proof electric heating tube, which includes a bundled electric heating tube main body 1, a heat insulation box body 7 and a glass fiber heat insulation sheet 16. The lower end of the bundled electric heating tube main body 1 passes through the combined flange 2 and is connected to the power connector 3. An installation groove 4 is opened on the upper right side of the combined flange 2. Side slots 5 are opened at both the front and rear ends inside the installation groove 4, and a contact groove 6 is opened at the left end inside the installation groove 4. The heat insulation box body 7 is located inside the installation groove 4. Bending grooves 12 are opened on the right sides of the front and rear ends of the heat insulation box body 7. First return springs 14 and bending blocks 13 are installed in both bending grooves 12. A temperature display instrument 9, a warning lamp bead 10 and a micro buzzer 11 are installed at the right end inside the heat insulation box body 7. Two second return springs 15 are installed at the left end inside the heat insulation box body 7. The other ends of the two second return springs 15 are connected to a glass fiber heat insulation sheet 16. A temperature detection head 17 is installed through the glass fiber heat insulation sheet 16. This design solves the problem that when the temperature of the original device is too high, it cannot give a warning reminder to external personnel, resulting in the safety of surrounding personnel not being guaranteed.

[0019] As the first embodiment of the present utility model: the lower right side of the bundled electric heating tube main body 1 passes through the contact groove 6, and the detection end of the temperature detection head 17 is located in the contact groove 6 and is in contact with the lower right side of the bundled electric heating tube main body 1. Through the added contact groove 6, it is convenient to install the temperature detection head 17. A heat insulation cover 8 is horizontally installed on the upper end of the heat insulation box body 7. The upper side of the temperature detection head 17 can be blocked by the added heat insulation cover 8.

[0020] The movable ends of the two first return springs 14 respectively abut against the two bending blocks 13, and the two bending blocks 13 are respectively clamped in the two side slots 5. Through the added two first return springs 14, the two bending blocks 13 can be pushed and clamped in the two side slots 5, thereby realizing the installation of the heat insulation box body 7. The right side of the temperature detection head 17 is connected to the temperature display instrument 9 through a wire. The added temperature display instrument 9 is a temperature instrument in the existing mature technology, and its working principle will not be elaborated.

[0021] As the second embodiment of the present utility model: First, pinch the two bent clamping blocks 13 towards each other, forcing the two first return springs 14 to compress. Then, place the heat insulation box body 7 in the installation groove 4, forcing the detection end of the temperature detection head 17 to be in the contact groove 6. Under the push of the two second return springs 15, the temperature detection head 17 is attached to the lower right side of the main body 1 of the cluster type electric heating tube until the heat insulation box body 7 is completely moved into the installation groove 4. Release the two bent clamping blocks 13, and the two first return springs 14 reset, pushing the two bent clamping blocks 13 to be stuck in the two side clamping grooves 5, thereby realizing the installation of the heat insulation box body 7. Then, power on the main body 1 of the cluster type electric heating tube through the power connector 3. After it heats up, the temperature detection head 17 detects it in real time and feeds it back to the temperature display instrument 9 for display. When its temperature is too high, the warning lamp bead 10 flashes, and at the same time, the micro buzzer 11 emits a warning sound, thereby warning and reminding the surrounding personnel.
