Description

Technical Field

[0001] This application relates to the field of electric heating belts, and more particularly to a clamp-type electric heating belt. Background Technology

[0002] Gas materials are mostly transported through pipelines, with metal pipelines being widely used due to their high structural strength. However, in low-temperature environments, the materials inside metal pipelines are easily affected by the external temperature. When the temperature in the gas pipeline is maintained within a certain range, the products generated during the process will not easily deposit or clog the pipeline, thus reducing the number of machine maintenance cycles and extending the life of related equipment. Therefore, electric heating belts are required.

[0003] The existing electric heating strips are installed by wrapping the heating strip around the pipe and then connecting the two ends with Velcro. However, after long-term use or during operation, the Velcro may loosen due to pulling on the heating strip, requiring reinstallation and reducing work efficiency. Utility Model Content

[0004] To address the aforementioned problems, this application provides a clamp-type electric heating belt.

[0005] The clamp-type electric heating belt provided in this application adopts the following technical solution:

[0006] An electric heating band with clamps includes an electric heating band body. The electric heating band body is provided with an installation assembly for fixing the electric heating band body to a pipe. The installation assembly includes two U-shaped fixing blocks fixedly connected to both ends of one side wall of the electric heating band body. Each U-shaped fixing block has two opposing arc-shaped clamping plates hinged inside. The ends of the arc-shaped clamping plates away from the U-shaped fixing blocks are respectively fixedly connected to a first connecting block and a second connecting block. The two side walls of the first connecting block are fixedly connected to fixing rods. A U-shaped clamping block is provided on one side of the first connecting block. The two ends of the U-shaped clamping block are rotatably connected to the fixing rods. The U-shaped clamping block is sleeved with the second connecting block. The second connecting block is provided with a connecting assembly for locking the U-shaped clamping block.

[0007] By adopting the above technical solution, during use, the electric heating belt body is first wrapped around the pipe. Then, by swinging the arc-shaped clamps on the U-shaped fixing block, the arc-shaped clamps are brought closer together. Then, by swinging the U-shaped clamps, the U-shaped clamps are fitted onto the second connecting block, connecting the first and second connecting blocks and connecting the arc-shaped clamps together. This allows them to abut against the pipe, thus installing the electric heating belt body on the pipe. This method minimizes the risk of the electric heating belt being pulled during prolonged use or operation, causing the Velcro to loosen and requiring reinstallation, which would reduce work efficiency.

[0008] Preferably, a first Velcro fastener is fixedly connected to one side of the lower surface of the electric heating belt body, one side of the first Velcro fastener extends out of the electric heating belt body, and the first Velcro fastener is adhered to the other side of the lower surface of the electric heating belt body.

[0009] By adopting the above technical solution, when the electric heating belt body is wrapped around the pipe, the two sides of the electric heating belt body are connected by the first Velcro, so that the electric heating belt body is pre-installed on the pipe, making it convenient to clamp the arc-shaped clip on the pipe.

[0010] Preferably, the connecting assembly includes a slide groove formed on one side wall of the second connecting block, the slide groove being close to the first connecting block, two push blocks being slidably disposed in the slide groove, a locking rod being fixedly connected to the opposite side wall of the two push blocks, the end of the locking rod away from the push block passing through the side wall of the slide groove and being inserted into the U-shaped locking block, and a spring being fixedly connected between the two push blocks.

[0011] By adopting the above technical solution, pressing the push block causes the spring to contract, moving the locking rod towards the slide groove. Then, the U-shaped locking block is placed on the second connecting block. Releasing the push block causes the spring to rebound, allowing the locking rod to be inserted into the U-shaped locking block, preventing the U-shaped locking block from detaching from the second connecting block and causing the arc-shaped locking plate to fall off the pipe.

[0012] Preferably, a guide rod is fixedly connected inside the groove, and the push blocks are all sleeved on the guide rod.

[0013] By adopting the above technical solution, the stability of the push block sliding in the groove can be improved by the guide rod, preventing the push block from shaking and causing the spring to bend after the locking rod is moved into the groove.

[0014] Preferably, the electric heating belt body includes an inner layer of cloth, a nickel-chromium heating wire is fixedly connected to the upper surface of the inner layer of cloth, an insulation layer is provided on the upper surface of the nickel-chromium heating wire, an outer layer of cloth is fixedly connected to the upper surface of the insulation layer, and the outer layer of cloth is fixedly connected to the inner layer of cloth.

[0015] By adopting the above technical solution, the inner layer of cloth is heated evenly by the nickel-chromium heating wire, which insulates the pipeline. The insulation layer can prevent heat loss and reduce energy consumption.

[0016] Preferably, an electric wire is provided on one side of the electric heating belt body, one end of the electric wire is electrically connected to the nickel-chromium heating wire, and the other end of the electric wire is electrically connected to a thermostat.

[0017] By adopting the above technical solution, the heating temperature of the nickel-chromium heating wire can be easily controlled by a temperature controller, thereby controlling the temperature of the pipeline.

[0018] Preferably, a second Velcro fastener is fixedly connected to the lower surface of the thermostat, and the second Velcro fastener is adhered to the electric heating belt body.

[0019] By adopting the above technical solution, after the electric heating belt body is installed on the pipe, the thermostat is glued to the electric heating belt body with the second Velcro, which prevents the thermostat from dangling and pulling on the wire, causing damage to the wire.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. This application utilizes the cooperative arrangement of structures such as the arc-shaped clamping plate, the first connecting block, and the second connecting block. During use, the electric heating belt body is first wrapped around the pipe. Then, by swinging the arc-shaped clamping plate on the U-shaped fixing block, the arc-shaped clamping plates are brought closer together. Next, by swinging the U-shaped clamping block, the U-shaped clamping block is fitted onto the second connecting block, connecting the first connecting block and the second connecting block, connecting the arc-shaped clamping plates together, and abutting against the pipe to install the electric heating belt body on the pipe. This minimizes the problem of the electric heating belt being pulled during long-term use or operation, causing the Velcro to loosen and requiring reinstallation, which reduces work efficiency.

[0022] 2. When wrapping the electric heating tape body around the pipe, the two sides of the electric heating tape body are connected by the first Velcro, so that the electric heating tape body is pre-installed on the pipe, making it easy to clip the arc-shaped clip plate onto the pipe.

[0028] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0029] This application discloses a clamp-type electric heating belt.

[0030] Reference Figure 1 , Figure 2 and Figure 3 A clamp-on electric heating belt includes an electric heating belt body 1, and an installation assembly for fixing the electric heating belt body 1 to a pipe is provided on the electric heating belt body 1. The installation assembly includes a U-shaped fixing block 2, an arc-shaped clamping plate 3, a first connecting block 4, a second connecting block 5, a fixing rod 6, and a U-shaped clamping block 7.

[0031] Two U-shaped fixing blocks 2 are provided and fixedly connected to both ends of the lower surface of the electric heating belt body 1. Two sets of arc-shaped clamping plates 3 are provided, with two in each set. Every two arc-shaped clamping plates 3 are hinged to one U-shaped fixing block 2. The ends of every two arc-shaped clamping plates 3 away from the U-shaped fixing block 2 are arranged opposite each other to form a clamp that fits the pipe. Two first connecting blocks 4 and two second connecting blocks 5 are provided and fixedly connected to the ends of the arc-shaped clamping plates 3 away from the U-shaped fixing blocks 2. The first connecting blocks 4 and the second connecting blocks 5 are arranged opposite each other. Multiple fixing rods 6 are provided and fixedly connected to the two side walls of the first connecting block 4. A U-shaped clamping block 7 is provided on one side of the first connecting block 4. The two ends of the U-shaped clamping block 7 are rotatably connected to the fixing rods 6 respectively. The U-shaped clamping block 7 is sleeved with the second connecting block 5. The second connecting block 5 is provided with a connecting component for locking the U-shaped clamping block 7.

[0032] Reference Figure 1 A first Velcro 8 is fixedly connected to one side of the lower surface of the electric heating tape body 1. The electric heating tape body 1 extends out from one side of the first Velcro 8 and is adhered to the other side of the lower surface of the electric heating tape body 1. When the electric heating tape body 1 is wrapped around the pipe, the two sides of the electric heating tape body 1 are connected by the first Velcro 8, so that the electric heating tape body 1 is pre-installed on the pipe, which makes it convenient to clip the arc-shaped clip 3 onto the pipe.

[0033] Reference Figure 2 and Figure 4The connecting assembly includes a groove 9 formed on one side wall of the second connecting block 5. The groove 9 is close to the first connecting block 4. Two push blocks 10 are slidably arranged in the groove 9. A locking rod 11 is fixedly connected to the side wall of the two push blocks 10 facing away from each other. The end of the locking rod 11 away from the push block 10 passes through the side wall of the groove 9 and is inserted into the U-shaped locking block 7. A spring 12 is fixedly connected between the two push blocks 10. By pressing the push block 10, the spring 12 is contracted, and the locking rod 11 is moved toward the groove 9. Then, the U-shaped locking block 7 is fitted onto the second connecting block 5. Then, the push block 10 is released, and the spring 12 rebounds, allowing the locking rod 11 to be inserted into the U-shaped locking block 7, preventing the U-shaped locking block 7 from detaching from the second connecting block 5 and causing the arc-shaped locking plate 3 to fall off the pipe.

[0034] Reference Figure 4 A guide rod 13 is fixedly connected inside the slide groove 9, and the push blocks 10 are all sleeved on the guide rod 13. The guide rod 13 can improve the stability of the push blocks 10 sliding in the slide groove 9 and prevent the push blocks 10 from shaking after the locking rod 11 is moved into the slide groove 9, which would cause the spring 12 to bend.

[0035] Reference Figure 1 and Figure 3 The electric heating belt body 1 includes an inner layer cloth 14, a nickel-chromium heating wire 15 is fixedly connected to the upper surface of the inner layer cloth 14, an insulation layer 16 is provided on the upper surface of the nickel-chromium heating wire 15, and an outer layer cloth 17 is fixedly connected to the upper surface of the insulation layer 16. The outer layer cloth 17 is fixedly connected to the inner layer cloth 14. The inner layer cloth 14 is uniformly heated by the nickel-chromium heating wire 15 to insulate the pipe. The insulation layer 16 can prevent heat loss and reduce energy consumption.

[0036] Reference Figure 1 The electric heating element body 1 has an electric wire 18 on one side. One end of the electric wire 18 is electrically connected to the nickel-chromium heating wire 15, and the other end of the electric wire 18 is electrically connected to a thermostat 19. The heating temperature of the nickel-chromium heating wire 15 can be easily controlled by the thermostat 19 to control the temperature of the pipeline.

[0037] Reference Figure 1 The lower surface of the thermostat 19 is fixedly connected with a second Velcro 20, which is adhered to the electric heating belt body 1. After the electric heating belt body 1 is installed on the pipe, the thermostat 19 is adhered to the electric heating belt body 1 by the second Velcro 20 to prevent the thermostat 19 from dangling and pulling the wire 18, which would cause damage to the wire 18.

[0038] The implementation principle of the clamp-on electric heating belt in this embodiment is as follows: In use, the electric heating belt body 1 is first wrapped around the pipe. The two sides of the electric heating belt body 1 are connected by the first Velcro 8, pre-installing the electric heating belt body 1 on the pipe. Then, by pressing the push block 10, the spring 12 contracts, moving the locking rod 11 towards the slide groove 9. Next, by swinging the U-shaped locking block 7, the U-shaped locking block 7 is fitted onto the second connecting block 5. Then, the push block 10 is released, causing the spring 12 to rebound, inserting the locking rod 11 into the U-shaped locking block 7 to prevent it from detaching from the second connecting block 5, connecting the first connecting block 4 and the second connecting block 5. The arc-shaped locking plates 3 are then connected and abut against the pipe, installing the electric heating belt body 1 on the pipe. The heating temperature of the nickel-chromium heating wire 15 is controlled by the thermostat 19 to regulate the pipe temperature. This minimizes the problem of the electric heating belt being pulled during prolonged use or operation, causing the Velcro to loosen and requiring reinstallation, thus reducing work efficiency.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
