Description

Technical Field

[0001] The utility model relates to the technical field of improved heating belts, in particular to an improved heating belt. Background Art

[0002] The heating tape is an electric heating device that converts electrical energy into thermal energy, and replenishes the heat lost by the heating equipment through the insulation material through direct or indirect heat exchange.

[0003] For example, a heating tape with the authorization announcement number "CN102014534A" has a neutral wire connected to another resistance wire, the ends of the two resistance wires are connected to each other, the ground wire is connected to the second ground wire, and the resistance wire and the second ground wire are wrapped with a thermally conductive insulating outer sheath. The resistance wire is used as a heating element, which has a long life and low cost. When the temperature is low, the heating is automatically started through the connected PTC thermostat. When the temperature rises, its internal resistance approaches infinity, the circuit is disconnected, and the heating is stopped. However, the heating tape is mostly installed by winding during use. If it is laid flat, it needs to be fixed with an external cable tie. In order to ensure a stable connection, the cable tie needs to be tightened, which can easily cause the heating tape to deform, affect the normal use of the heating tape, and shorten the service life of the heating tape. Utility Model Content

[0004] The utility model aims to solve the problem of affecting the normal use of the heating belt and shortening the service life of the heating belt, and proposes an improved heating belt.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An improved heating belt is designed, including a jacket, wherein the upper and lower sides of the jacket are respectively connected with mounting structures, wherein the mounting structure includes a bent rod and a rope, wherein the inner sides of a plurality of the bent rods are respectively fixedly connected with the upper and lower sides of the jacket, the outer walls of the bent rods are wound and connected with the outer walls of the rope, and a round sleeve is fixedly connected with the end of the outer wall of the rope.

[0007] Preferably, the inner wall of the outer sleeve is fixedly connected to the outer wall of the shielding layer.

[0008] Preferably, the inner wall of the shielding layer is fixedly connected to the inner layer.

[0009] Preferably, a semi-conductive core is fixedly connected to the inner wall of the inner layer.

[0010] Preferably, a copper wire is fixedly connected to the inner wall of the semi-conductive core.

[0011] Preferably, a straight tube is inserted in front of the outer wall of the copper wire.

[0012] The utility model proposes an improved heating belt, which has the following beneficial effects: the outer wall of the outer jacket in the installation structure is fitted with the specified position, and then the rope is wrapped around the fitting position, and the rope is tightened at the same time, and then the two ropes are knotted. At this time, the outer jacket is fixed at the fitting position, and the rope is tightened at the same time, which ensures that the heating belt is installed stably without causing compression and deformation to the heating belt as a whole, and the internal wire core of the heating belt will not be damaged due to compression, thereby ensuring the normal use of the heating belt and ensuring the service life of the heating belt.

[0020] By fitting the outer wall of the outer jacket 1 in the installation structure 2 with the designated position, the rope 202 is then wrapped around the fitting position, and the rope 202 is tightened at the same time, and then the two ropes 202 are knotted. At this time, the outer jacket 1 will be fixed at the fitting position, and the rope 202 will be tightened at the same time, which ensures that the heating belt is installed stably without causing compression and deformation to the heating belt as a whole, and the internal wire core of the heating belt will not be damaged due to compression, thereby ensuring the normal use of the heating belt and ensuring the service life of the heating belt.
