Technical Field

[0001] This utility model belongs to the field of heating wire fixing technology, specifically a heating wire fixing device. Background Technology

[0002] Heating cables are cable structures that use electricity as their energy source and utilize alloy resistance wires or carbon fiber heating elements to generate heat through far-infrared radiation. Silicone rubber heating and insulation wires are wires that use silicone rubber as insulation material. They have excellent high-temperature resistance and stable heating effect and are used in electric underfloor heating systems.

[0003] A Chinese patent with authorization announcement number CN214799928U discloses a fixing device for carbon fiber heating wire, relating to the field of fixing devices. This utility model includes a fixing body and a carbon fiber heating wire body. The fixing body is connected to a fastening block via a snap-fit ​​assembly, with the fastening block located inside the snap-fit ​​assembly. This utility model is a fixing device for carbon fiber heating wire. It increases the service life of the support arm through springs, makes installation and disassembly more flexible and convenient, and provides a firm and stable installation, facilitating the effective aggregation of carbon fiber and increasing the size of the carbon fiber heating wire.

[0004] However, the above solution still has some problems. The device can only fix the position of the heating wire, but when two sets of heating wires are connected, the fastening block is used to fix the two. During use, the connection is prone to loosening, which leads to unstable operation of the heating wire. Therefore, a heating wire fixing device is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and address the problems of existing equipment, this utility model proposes a heating wire fixing device.

[0006] The technical solution adopted by this utility model to solve its technical problem is a heating wire fixing device, including: a first heating wire and a second heating wire. Multiple sets of reinforcing rings are sleeved around the first and second heating wires. A first connecting plate is fixedly connected to one side of each set of reinforcing rings, and a second connecting plate is fixedly connected to the other side of each reinforcing ring. An insertion hole is provided on one side of the first connecting plate, and an exhaust hole is provided on the second connecting plate. Threaded holes are provided on both the first and second connecting plates, and reinforcing bolts are threaded into the internal threads of the threaded holes. A baffle is fixedly connected to one end of each reinforcing bolt, and the baffle is located on one side of the first connecting plate. A limiting rod is fixedly connected to one side of the second connecting plate, and the limiting rod is located on one side of the exhaust hole. Positioning grooves are symmetrically provided inside the limiting rod. When the connecting rod is subjected to force and moves inward toward the limiting rod, the gas inside the limiting rod can be discharged outward through the exhaust hole.

[0007] Preferably, a connecting rod is slidably connected inside the limiting rod, and a rubber pad is fixedly connected to one end of the connecting rod. The connecting rod is movably connected inside the socket. When the rubber pad is inserted into the socket, the connecting rod simultaneously enters the socket and cooperates with the limiting rod to connect the first connecting plate and the second connecting plate.

[0008] Preferably, a limiting plate is fixedly connected to the other end of the connecting rod, and a first elastic sheet is symmetrically fixedly connected to the limiting plate. A positioning block is fixedly connected to the first elastic sheet, and the positioning block is movably connected to the positioning groove. The elastic force of the first elastic sheet pushes the positioning block into the positioning groove, and the positions of the first connecting plate and the second connecting plate are initially fixed by the connecting rod and the rubber pad.

[0009] Preferably, both the first heating wire and the second heating wire are provided with U-shaped buckles, and both ends of the U-shaped buckles are fixedly connected to support plates. A connecting frame is fixedly connected to one side of the support plate, and an adjusting bolt is threaded inside the connecting frame. The adjusting bolt rotates inside the connecting frame, thereby supporting the adjusting bolt and preventing it from falling off.

[0010] Preferably, the connecting frame is symmetrically provided with positioning frames, one end of the connecting frame is fixedly connected with a spring, one end of the spring is fixedly connected with a reinforcing plate, and one side of the reinforcing plate is fixedly connected with an adjusting rod. After the reinforcing plate enters the slot, it is tightly attached to the inner wall of the slot under the action of the spring.

[0011] Preferably, the adjusting rod is slidably connected inside the connecting frame, and the connecting frame is symmetrically provided with fixing plates. A second elastic piece is installed on one side of the fixing plate. The second elastic piece is fixedly connected to the adjusting rod, and the adjusting bolt is rotatably connected to the adjusting rod. When the pressure on the second elastic piece decreases, the two sets of fixing plates are pushed out, so that the fixing plates are in contact with the inner wall of the slot.

[0012] The advantages of this utility model are: by connecting the two ends of the two sets of heating wires with multiple sets of fixing rings, the movement range of the connection ends is limited. Then, the rubber pad is inserted into the socket to connect the two ends of the reinforcing ring. The reinforcing bolt is screwed into the threaded hole. During the rotation, the baffle presses against the first connecting plate, thereby reducing the size of the reinforcing ring and improving the firmness of the connection between the two sets of heating wires, so as to ensure the stability of the heating wire operation during the use of the electric floor heating system.

[0013] This invention pushes the adjusting rod outward by rotating the adjusting bolt, which in turn moves the two sets of fixing plates downward, causing them to move out of the positioning frame. As the pressure on the second elastic plate decreases, the two sets of fixing plates are pushed out, so that the fixing plates are in contact with the inner wall of the slot. At the same time, after the reinforcing plate enters the slot, it is driven by the spring to fit tightly against the inner wall of the slot, thereby improving the tightness of the contact with the inside of the slot and thus improving the fixing strength of the heating wire.

[0022] Please see Figure 1-5As shown, a heating wire fixing device includes: a first heating wire 1 and a second heating wire 2. Multiple sets of reinforcing rings 3 are sleeved around the outside of the first heating wire 1 and the second heating wire 2. A first connecting plate 4 is fixedly connected to one side of each set of reinforcing rings 3, and a second connecting plate 27 is fixedly connected to the other side of each set of reinforcing rings 3. An insertion hole 5 is provided on one side of the first connecting plate 4, and an exhaust hole 6 is provided on the second connecting plate 27. Threaded holes 7 are provided on both the first connecting plate 4 and the second connecting plate 27. A reinforcing bolt 8 is threadedly connected to the inside of each threaded hole 7. A baffle 9 is fixedly connected to one end of each reinforcing bolt 8. The baffle 9 is located at the... A limiting rod 10 is fixedly connected to one side of a connecting plate 4 and one side of a second connecting plate 27. The limiting rod 10 is located on one side of an exhaust hole 6. A positioning groove 11 is symmetrically opened inside the limiting rod 10. A connecting rod 12 is slidably connected inside the limiting rod 10. A rubber pad 13 is fixedly connected to one end of the connecting rod 12. The connecting rod 12 is movably connected inside the insertion hole 5. A limiting plate 14 is fixedly connected to the other end of the connecting rod 12. A first elastic piece 15 is symmetrically fixedly connected to the limiting plate 14. A positioning block 16 is fixedly connected to the first elastic piece 15. The positioning block 16 is movably connected to the positioning groove 11.

[0023] Heating cables are manufactured with a cable structure, utilizing alloy resistance wire or carbon fiber heating elements to generate heat through far-infrared current. They are used in electric underfloor heating systems. Since electric underfloor heating systems require numerous heating wires during installation, it is necessary to connect both ends of each set of heating wires, ensuring the tightness and firmness of the connections to guarantee the stability of the heating wires during system operation. In actual use, the connecting ends of the first heating wire 1 and the second heating wire 2 are placed inside the reinforcing ring 3. Then, the rubber pad 13 is inserted into the socket 5, positioning it on one side of the first connecting plate 4. Through the cooperation of the rubber pad 13, the connecting rod 12, and the limiting rod 10, the first connecting plate 4 and the second connecting plate 4 are secured. The connecting plate 27 is initially connected and fixed. The reinforcing bolt 8 is screwed into the threaded hole 7. During the rotation, the baffle 9 presses against the first connecting plate 4 and pushes the connecting rod 12 into the limiting rod 10, causing the positioning block 16 to move synchronously. When the positioning block 16 is located behind the positioning groove 11, the elastic force of the first elastic piece 15 pushes the positioning block 16 into the positioning groove 11, initially fixing the position of the connecting rod 12 and the rubber pad 13. In cooperation with the reinforcing bolt 8 and the baffle 9, the first connecting plate 4 and the second connecting plate 27 are further fixed, which can reduce the size of the reinforcing ring 3 and improve the tightness of the connection between the first heating wire 1 and the second heating wire 2, thereby making the operation of the heating wire more stable.

[0024] Please see Figure 1-5As shown, both the first heating wire 1 and the second heating wire 2 are provided with U-shaped buckles 17. Both ends of the U-shaped buckles 17 are fixedly connected to support plates 18. A connecting frame 19 is fixedly connected to one side of the support plate 18. An adjusting bolt 20 is threaded inside the connecting frame 19. A positioning frame 21 is symmetrically arranged on the connecting frame 19. A spring 22 is fixedly connected to one end of the connecting frame 19. A reinforcing plate 23 is fixedly connected to one end of the spring 22. An adjusting rod 24 is fixedly connected to one side of the reinforcing plate 23. The adjusting rod 24 is slidably connected inside the connecting frame 19. A fixing plate 25 is symmetrically arranged on the connecting frame 19. A second elastic piece 26 is installed on one side of the fixing plate 25. The second elastic piece 26 is fixedly connected to the adjusting rod 24. The adjusting bolt 20 is rotatably connected to the adjusting rod 24.

[0025] When fixing the heating wire to the ground slot, the U-shaped buckle 17 is placed on the first heating wire 1 and the second heating wire 2. The connecting frame 19 is inserted into the ground slot through the two sets of support plates 18. Then, the adjusting bolt 20 is rotated toward the adjusting rod 24, applying a pushing force into the slot to the adjusting rod 24. At the same time, the two sets of fixing plates 25 are moved downward, causing them to move out of the positioning frame 21. The pressure on the second elastic piece 26 decreases, pushing the two sets of fixing plates 25 outward, so that the fixing plates 25 are in contact with the inner wall of the slot. At the same time, the reinforcing plate 23 enters the slot. Then, driven by the spring 22, it adheres tightly to the inner wall of the slot, thereby increasing the tightness of the contact with the inside of the slot on the ground, which in turn increases the fixing strength of the heating wire. The adjusting bolt 20 is rotated in the opposite direction, which drives the adjusting rod 24 to move into the connecting frame 19. This causes the fixing plate 25 to adhere to the connecting frame 19 through the second elastic piece 26. At the same time, the second elastic piece 26 is squeezed, which in turn drives the two sets of fixing plates 25 into the interior of the positioning frame 21, fixing the position of the fixing plate 25. This releases the fixing of the heating wire, making it easy to disassemble.

[0026] Working principle: Electric underfloor heating requires numerous heating wires during installation. The ends of each set of heating wires need to be connected. The connecting ends of the first heating wire 1 and the second heating wire 2 are placed inside the reinforcing ring 3. Then, the rubber pad 13 is inserted into the socket 5, initially connecting and fixing the first connecting plate 4 and the second connecting plate 27. The reinforcing bolt 8 is screwed into the threaded hole 7. During rotation, the baffle 9 presses against the first connecting plate 4, simultaneously pushing the connecting rod 12 into the limiting rod 10. When the positioning block 16 is located behind the positioning groove 11, the elastic force of the first elastic piece 15 pushes the positioning block 16 into the positioning groove 11, initially fixing the positions of the connecting rod 12 and the rubber pad 13. Combined with the reinforcing bolt 8 and the baffle 9, the number of turns of the reinforcing ring 3 can be reduced. To improve the tightness of the connection between the first heating wire 1 and the second heating wire 2, the U-shaped buckle 17 is fitted onto the first heating wire 1 and the second heating wire 2. The connecting frame 19 is inserted into the ground slot through the two sets of support plates 18. Then, the adjusting bolt 20 is rotated toward the adjusting rod 24, which applies a pushing force into the slot to the adjusting rod 24. At the same time, the two sets of fixing plates 25 are moved down, causing them to move out of the positioning frame 21. The pressure on the second elastic piece 26 is reduced, pushing the two sets of fixing plates 25 outward, so that the fixing plates 25 are in contact with the inner wall of the slot. At the same time, after the reinforcing plate 23 enters the slot, it is tightly in contact with the inner wall of the slot under the action of the spring 22, thereby improving the tightness of contact with the inside of the ground slot and thus improving the fixing strength of the heating wire.
