Description

Technical Field

[0001] This application relates to the field of heating belts, and more particularly to a heating belt that is easy to install and remove. Background Technology

[0002] Heating belts are typically used to maintain the temperature of vacuum pipelines and gas pipelines, ensuring uniform heating of the pipelines and preventing dust accumulation. When the temperature in the gas pipeline is maintained within a certain range, the byproducts generated during the process will not easily accumulate or clog the pipeline, thus reducing the frequency of machine maintenance and extending the lifespan of related equipment.

[0003] However, existing heating bands are usually rectangular. When using them, the two ends are directly connected to wrap the pipe. When wrapping some curved pipes, a large number of heat-conducting wires tend to accumulate at the crooked inner diameter, resulting in excessive heat. In addition, when existing heating bands are connected in pairs, gaps are easily left in the middle. Furthermore, adjacent heating bands do not have the function of mutual power transmission, requiring separate power supplies for multiple heating bands, which is inconvenient to use. Utility Model Content

[0010] By adopting the above technical solution, when it is necessary to wrap a curved pipe, the two sets of hinge rods on both sides are placed at the outer diameter and inner diameter of the curved pipe, respectively. When bending, the set of hinge rods at the inner diameter will be recessed inward, while the set of hinge rods at the outer diameter will be curved outward. Then, the fastening bolts are rotated to limit the hinge rods. The connecting rope connects the insulation tape to the hinge rods, maintaining the shape of the insulation tape and preventing multiple heating wires from touching and piling up.

[0011] Preferably, the outer fabric strip, inner fabric strip, and insulation strip are all arranged in a rectangular block shape, and the two ends of the insulation strip are fixed with zippers, and the two zippers are used together.

[0014] By adopting the above technical solution, when it is necessary to connect the upper and lower heating bands, the first Velcro of the bottom heating band is connected to the second Velcro of the top heating band to connect the two.

[0015] Preferably, the strap is double-layered, with an elastic band movably sleeved inside the strap cavity, and one end of the elastic band is located outside the strap cavity, with a limit buckle provided at one end of the elastic band.

[0016] By adopting the above technical solution, after all the heating belts are connected, the elastic strap is pulled to limit the use of the limit buckle, so as to keep the strap tightly attached to the pipeline.

[0019] In summary, this application includes at least the following beneficial technical effects:

[0020] 1. When it is necessary to wrap a curved pipe, the two sets of hinge rods on both sides are placed at the outer diameter and inner diameter of the curved pipe, respectively. When bending, the set of hinge rods at the inner diameter will be recessed inward, while the set of hinge rods at the outer diameter will be curved outward. Then, the fastening bolts are rotated to limit the hinge rods. The connecting rope connects the insulation tape to the hinge rods, maintaining the shape of the insulation tape to prevent multiple heating wires from touching and piling up. This achieves the effect of being able to bend freely, and being able to quickly limit the bending after bending to prevent the heating wires from touching each other and causing overheating.

[0021] 2. In this application, the first Velcro strap of the bottom heating band is connected to the second Velcro strap of the top heating band.
