Description

Technical Field

[0001] This utility model relates to the field of electric heating tape technology, specifically an electric heating tape that heats up rapidly. Background Technology

[0002] Electric heating cables consist of a conductive polymer, two parallel metal wires, and an insulating sheath. Their key feature is the high positive temperature coefficient of the conductive polymer, which, when connected in parallel, automatically adjusts its output power according to the temperature changes of the heated system, automatically limiting the heating temperature. They can be cut to any length or extended within a certain range, and can be repeatedly overlapped without risk of overheating or burning. Electric heating cables are highly efficient, energy-saving, easy to use, pollution-free, and have a long service life. They heat pipes using a heat tracing medium and are suitable for pipelines and large-capacity tanks. They exhibit a small temperature gradient, long stabilization time, are portable, and easy to operate. Furthermore, electric heating cables are very safe and will not cause injury. Their applications are very wide-ranging; they can be used for heating pipelines to prevent condensation in winter, ensuring normal water transport. They can also be used for snow melting on roofs, floors, or other areas in winter to prevent snow accumulation and ensure unobstructed roads.

[0003] Existing fast-heating electric heating cables are often laid on the surface of the component that needs to be heated. However, this makes it difficult to firmly fix the electric heating cable to the surface of the component, which can easily lead to displacement later. This results in uneven heating of the component surface, or the cable can only be fixed in one place, without the flexibility to adjust or add fixing points, which is very inconvenient to use. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a fast-heating electric heating cable, which solves the problems that often occur when the electric heating cable is laid on the surface of the component to be heated. However, this often results in the electric heating cable not being firmly fixed to the surface of the component, which can easily lead to displacement later, resulting in uneven heating of the component surface. Alternatively, it can only be fixed in one place, without the flexibility to adjust or add fixing points, which is very inconvenient to use.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a rapid heating electric heating tape, comprising two electrically conductive heating wires. Each of the two heating wires is covered with an insulating layer, and the insulating layer is covered with a waterproof layer. A buffer layer is commonly covered around the two waterproof layers. An elastic hard shell layer is covered around the buffer layer, and an outer sheath is covered around the elastic hard shell layer. The top and bottom of the buffer layer, the elastic hard shell layer, and the outer sheath are all recessed. Fixing mechanisms are provided on both sides of the outer sheath. A first groove is formed in the center of the buffer layer, and a first buffer spring is elastically connected inside the first groove. Second grooves are formed on both sides of the buffer layer, and second buffer springs are elastically connected inside the second grooves. In this invention, during use... The electric heating cable conducts electricity and heats up, and uses insulation and waterproof layers for insulation and waterproofing respectively, making the electric heating cable more stable and safe during use. The buffer layer provides some cushioning when the electric heating cable is subjected to external forces, and the first and second buffer springs further buffer the forces received, preventing external forces from acting directly on the electric heating cable, thus protecting it and extending its service life. By making the top and bottom of the electric heating cable concave, the contact area between the electric heating cable and the part to be heated is increased, thereby transferring heat to the part to be heated more quickly, improving heating efficiency, and increasing the contact area between the electric heating cable and the part, improving the stability of the electric heating cable when fixed.

[0006] Preferably, multiple first grooves, first buffer springs, second grooves, and second buffer springs are provided. The second buffer springs are symmetrically distributed around the outside of the electric heat-conducting wire. In this invention, by providing multiple first buffer springs and second buffer springs, the external forces on the electric heat tracing cable can be buffered, which can play a certain protective role for the electric heat tracing cable and extend its service life.

[0007] Preferably, the fixing mechanism includes a slide bar, which is fixedly connected to the surface of the outer skin. A sliding hole is provided on one side of the slide bar. Reinforcing ribs are fixedly connected to the top and bottom of the slide bar. One side of the reinforcing ribs is fixedly connected to the surface of the outer skin. A fixing rope is provided on one side of the slide bar.

[0008] Preferably, the slider is slidably connected inside the slider, one side of the slider passes through the sliding hole and is fixedly connected to one end of the fixing rope, the top and bottom of the slider are provided with through holes, and the inner surface of the slider is provided with a groove, and the number of grooves is set to multiple.

[0009] Preferably, a receiving groove is provided on one side of the slider, the receiving groove is located on one side of the card slot, a moving hole is provided on the top of the slider, a card block is slidably connected inside the receiving groove, and a push handle is fixedly connected to one side of the top of the card block, the push handle is located on the side away from the card slot.

[0010] In this invention, the fixing mechanism allows for convenient fixation of the electric heating cable to the component requiring heating. During fixation, the slider is first slid into the side of the slide bar, then moved to the desired fixing position and slid to the side of the slot closest to that position. Since the top of the slide bar has a sliding hole, a hand can push the push handle through the hole, pushing the locking block into the slot, thus fixing the slider within the slide bar. Similarly, the other slider is fixed, and then secured with fixing ropes on both sides. If multiple fixing positions are needed, sliders can be further slid into the slide bar and fixed with fixing ropes. This fixing mechanism effectively secures the electric heating cable to the component requiring heating, increasing stability during use. The fixing position can be changed as needed, improving flexibility. The use of fixing ropes can be increased or decreased as required, further enhancing the flexibility of the fixing mechanism. Furthermore, the slider can be removed and reused when not in use, reducing consumable costs.

[0011] Preferably, limiting blocks are fixedly connected to both sides of the card block, with the limiting blocks located on the side away from the card slot. A limiting groove is formed inside the slider, with the limiting groove located on the front and back of the receiving groove. The limiting blocks are slidably connected inside the limiting groove. In this invention, by setting the limiting blocks and limiting grooves, the card block can move in one direction when pushed, preventing the card block from flipping in the receiving groove and improving the stability of the card block when moving in the receiving groove. Furthermore, the push handle and moving hole can prevent the card block from moving out of the receiving groove. At the same time, by setting the limiting blocks and limiting grooves, the card block can be further restricted from moving out of the receiving groove, improving the stability of the card block when pushed and used.

[0012] (III) Beneficial Effects This invention provides a rapidly heating electric heating tape. It has the following beneficial effects: (i) The electric heating cable with rapid heating has a fixing mechanism that allows for easy fixing of the electric heating cable to the parts that need to be heated, thereby increasing the stability of the electric heating cable during use, preventing displacement of the electric heating cable, ensuring uniformity and stability during heating, and allowing the fixing position to be changed as needed, thus improving the flexibility of use. At the same time, the use of fixing ropes can be added or reduced as needed, increasing the flexibility of the fixing mechanism during use. When not in use, the slider can be removed for reuse, reducing the use of consumables and lowering the cost of use.

[0013] (ii) The electric heating cable that heats up rapidly can buffer the external forces on the electric heating cable through the setting of the buffer layer, the first buffer spring and the second buffer spring, which can play a certain protective role and extend the service life of the electric heating cable.

[0014] (iii) The electric heating cable with rapid heating can increase the contact area between the electric heating cable and the component that needs to be heated by setting the top and bottom of the electric heating cable in a concave shape, thereby transferring heat to the component that needs to be heated more quickly, improving heating efficiency, and increasing the contact area between the electric heating cable and the component can improve the stability of the electric heating cable when it is fixed.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] See Figure 1-7 This utility model provides a technical solution: a rapid heating electric heating tape, the structure of which includes two electrically conductive heating wires 1. An insulating layer 2 is fitted over the two electrically conductive heating wires 1. A waterproof layer 3 is fitted over the insulating layer 2. A buffer layer 4 is fitted over both waterproof layers 3. An elastic hard shell layer 5 is fitted over the buffer layer 4. An outer skin 6 is fitted over the elastic hard shell layer 5. The top and bottom of the buffer layer 4, the elastic hard shell layer 5, and the outer skin 6 are all recessed. Fixing mechanisms 7 are provided on both sides of the outer skin 6. A first groove 8 is formed in the middle of the interior of the buffer layer 4. A first buffer spring 9 is elastically connected inside the first groove 8. Second grooves 10 are formed on both sides of the interior of the buffer layer 4. Second buffer springs 11 are elastically connected inside the second grooves 10. Specifically, in use, the heating is achieved through the electrically conductive heating wires 1. The heating element conducts heat and is insulated and waterproofed by the insulation layer 2 and waterproof layer 3, respectively, making the heating wire 1 more stable and safe during use. The buffer layer 4 provides cushioning when the heating wire is subjected to external forces. The first buffer spring 9 and the second buffer spring 11 further buffer the forces, preventing external forces from directly acting on the heating wire 1, thus protecting it and extending its service life. By making the top and bottom of the heating wire concave, the contact area between the heating wire and the component to be heated is increased, allowing heat to be transferred to the component more quickly, improving heating efficiency. Increasing the contact area between the heating wire and the component also improves the stability of the heating wire when fixed.

[0019] The first groove 8, the first buffer spring 9, the second groove 10, and the second buffer spring 11 are all provided in multiples. The second buffer spring 11 is symmetrically distributed around the outside of the electric heat-conducting wire 1. Specifically, by providing multiple first buffer springs 9 and second buffer springs 11, the external forces on the electric heat tracing cable can be buffered, which can play a certain protective role for the electric heat tracing cable and extend its service life.

[0020] The fixing mechanism 7 includes a slide bar 71, which is fixedly connected to the surface of the outer skin 6. A sliding hole 72 is provided on one side of the slide bar 71. Reinforcing ribs 73 are fixedly connected to the top and bottom of the slide bar 71. One side of the reinforcing ribs 73 is fixedly connected to the surface of the outer skin 6. A fixing rope 74 is provided on one side of the slide bar 71.

[0021] The slider 71 has a slider 75 slidably connected inside. One side of the slider 75 passes through the sliding hole 72 and is fixedly connected to one end of the fixing rope 74. The top and bottom of the slider 71 have through holes 76, and the inner surface of the slider 71 has a slot 77. The number of slots 77 is set to multiple.

[0022] The slider 75 has a receiving groove 78 on one side, which is located on one side of the slot 77. The top of the slider 75 has a moving hole 79. A locking block 710 is slidably connected inside the receiving groove 78. A push handle 711 is fixedly connected to the top side of the locking block 710, which is located on the side away from the slot 77.

[0023] Specifically, the fixing mechanism 7 allows for easy fixing of the electric heating cable to the component requiring heating. During fixing, first, slide the slider 75 into the side of the slide bar 71. Then, move the slider 75 to the desired fixing position and slide it to the side of the slot 77 closest to the desired position. Since the top of the slide bar 71 has a sliding hole 72, a hand can push the push handle 711 through the sliding hole 72. The push handle 711 pushes the locking block 710 into the slot 77, causing the locking block 710 to engage with the slot 77, thus fixing the slider 75 within the slide bar 71. Similarly... The other slider 75 is fixed, and then secured by the fixing ropes 74 on both sliders 75. If multiple fixing positions are required, the slider 75 can be slid further into the slider 71 and fixed. After fixing the slider 75, it can be secured by the fixing ropes 74. Through the setting of the fixing mechanism 7, the electric heating tape and the parts to be heated can be fixed, thereby increasing the stability during use. The fixing position can be changed as needed, improving the flexibility during use. At the same time, multiple fixing ropes 74 can be used for fixing to increase the firmness.

[0024] The locking block 710 has limiting blocks 712 fixedly connected to both sides. The limiting blocks 712 are located on the side away from the locking slot 77. The slider 75 has a limiting groove 713 inside. The limiting groove 713 is located on the front and back of the receiving slot 78. The limiting blocks 712 are slidably connected inside the limiting groove 713. Specifically, by setting the limiting blocks 712 and the limiting groove 713, the locking block 710 can move in one direction when pushed, preventing the locking block 710 from flipping in the receiving slot 78 and improving the stability of the locking block 710 when moving in the receiving slot 78. Furthermore, the push handle 711 and the moving hole 79 can prevent the locking block 710 from moving out of the receiving slot 78. At the same time, by setting the limiting blocks 712 and the limiting groove 713, the locking block 710 can be further restricted from moving out of the receiving slot 78, improving the stability of the locking block 710 when pushed.
