[0002] Electric heat tracing wire is a special type of wire used to maintain the temperature of pipes, equipment, etc. It generates heat through electric current and transfers this heat to the object being heated, preventing the medium inside the pipe from freezing, solidifying, or increasing in viscosity due to excessively low temperatures, thus ensuring the normal operation of the process. The electric heat tracing wire safety fixing device is designed to ensure the normal operation of the electric heat tracing wire. It firmly fixes the electric heat tracing wire to the surface of the pipe or equipment, preventing the wire from falling off or being damaged due to vibration, displacement, or other factors. It also ensures full contact between the wire and the object being heated, ensuring effective heat transfer and improving the safety and reliability of the electric heat tracing system.
[0003] However, current fixing devices have the following drawbacks: Inconvenient disassembly: The edge design of existing fixing devices is not conducive to disassembly, making it difficult for staff to operate during replacement and maintenance, wasting time and effort, affecting work efficiency, and making it difficult to quickly handle device malfunctions or replace aging parts. Guiding limitations: They cannot effectively guide wires at different angles and directions, making it difficult for wires to smoothly enter the clamping area, affecting clamping stability, lacking versatility, and unable to adapt to diverse installation scenarios. In response to this technical problem, this application proposes a safety fixing device for electric heat tracing wires. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a safety fixing device for electric heat tracing wires. This device allows for disassembly at the edges, facilitating replacement and maintenance by staff, thus improving the device's convenience. It also guides wires from different angles and directions, making it easier to clamp and fix the wires, thereby improving the device's versatility and clamping stability.
[0005] To achieve the above objectives, the present invention provides the following technical solution: A safety fixing device for an electric heat tracing wire includes a base plate and a top plate, which are connected by a snap-fit assembly to fix them together. A sliding groove is provided in the middle of the top side of the top plate, and a fixing component is provided inside the sliding groove to fix the wire. Rotary seats are rotatably connected to the front and rear sides of the top side of the top plate. A guide ring is fixedly connected to the top side of the rotary seat, and a positioning component is provided on the outer wall of the rotary seat to fix the position of the rotary seat.

[0007] Furthermore, a sloping plate is fixedly connected to the bottom side of the second dovetail plate, and a snap-fit plate is fixedly connected to the rear side of the sloping plate. Two snap-fit grooves are opened on the rear side of the top side of the bottom plate, and the snap-fit plate is engaged inside the snap-fit grooves. A lever plate is connected to the rear side of the snap-fit plate by a torsion spring.
[0008] Furthermore, the fixing assembly includes a bidirectional screw rotatably connected inside the slide groove, and two clamping rings are threadedly connected to the outer wall of the bidirectional screw, the clamping rings being slidably connected inside the slide groove.
[0009] Furthermore, the front side of the top plate is rotatably connected to a first rotating handle via a damping shaft, and the front end of the bidirectional screw is fixedly connected to the inside of the first rotating handle.

[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] Reference Figure 1 and Figure 2This utility model provides an embodiment of a safety fixing device for an electric heat tracing wire, comprising a base plate 1 and a top plate 3 connected together. A groove is formed in the center of the top side of the top plate 3. Rotary seats 2 are rotatably connected to both the front and rear sides of the top side of the top plate 3. Guide rings 5 are fixedly connected to the top sides of the rotary seats 2, guiding the wire through the guide rings 5 to facilitate subsequent fixing of the wire by the operator. (Refer to...) Figure 3 and Figure 4 Two first dovetail plates 7 are fixedly connected to the front side of the top side of the base plate 1, and two second dovetail plates 9 are fixedly connected to the rear side of the bottom side of the top plate 3. Two dovetail grooves are formed on both the rear side of the top side of the base plate 1 and the front side of the bottom side of the top plate 3. The first dovetail plates 7 are inserted into the front dovetail groove, and the second dovetail plates 9 are inserted into the rear dovetail groove. The base plate 1 and the top plate 3 are connected together by inserting the first dovetail plates 7 and the second dovetail plates 9 into the dovetail grooves. (Refer to...) Figure 3 , Figure 5 and Figure 6 The bottom side of the second dovetail plate 9 is fixedly connected to an inclined plate 10, and the rear side of the inclined plate 10 is fixedly connected to a buckle plate 11. Two buckle slots are opened on the rear side of the top side of the bottom plate 1. The buckle plate 11 is engaged in the buckle slots. The rear side of the buckle plate 11 is connected to a lever plate 12 by a torsion spring. The buckle plate 11 is engaged in the buckle slot by the inclined plate 10 which has a certain elastic connection with the second dovetail plate 9, thereby fixing the inclined plate 10 and fixing the second dovetail plate 9 in the dovetail slot on the rear side, thereby fixing the bottom plate 1 and the top plate 3 together. The lever plate 12 is used to move the inclined plate 10 to disengage the buckle plate 11 from the buckle slot, thereby disassembling the second dovetail plate 9.
[0019] Reference Figure 1 and Figure 2 A bidirectional screw 4 is rotatably connected inside the chute. Two clamping rings 6 are threaded onto the outer wall of the bidirectional screw 4 and slidably connected inside the chute. A first rotating handle 8 is rotatably connected to the front side of the top plate 3 via a damping shaft. The front end of the bidirectional screw 4 is fixedly connected inside the first rotating handle 8. The bidirectional screw 4 is rotated via the first rotating handle 8, thereby adjusting the distance between the two clamping rings 6 and clamping and fixing the wire. (Refer to...) Figure 1 , Figure 2 and Figure 7A fixing block 13 is fixedly connected to the outer wall of the rotating base 2. A plug rod 14 is slidably connected inside the fixing block 13. Multiple slots are provided on the front and rear sides of the top side of the top plate 3. The plug rod 14 is inserted into the slot. The rotating base 2 is fixed by inserting the plug rod 14 into the slot, thereby fixing the angle of the guide ring 5, so that the guide ring 5 can guide the wires in different angle directions. A threaded rod 15 is threadedly connected inside the plug rod 14. A second rotating handle 16 is rotatably connected to the top side of the fixing block 13 through a damping shaft. The top end of the threaded rod 15 is rotatably connected inside the fixing block 13, and the top end of the threaded rod 15 is fixedly connected inside the second rotating handle 16. The threaded rod 15 is rotated by the second rotating handle 16, thereby driving the plug rod 14 to insert into or disengage from the slot, so that the rotating base 2 is fixed or can rotate.
[0020] Working principle: First, the base plate 1 is fixed to the location where the wire needs to be fixed using bolts and nuts. Then, the top plate 3 is placed on the base plate 1, and the top plate 3 is slowly pushed to make it overlap with the base plate 1. During this process, the first dovetail plate 7 will slowly insert into the front dovetail groove. At the same time, the lever 12 pulls the latching plate 11, causing it to move the inclined plate 10 upwards so that the inclined plate 10 is attached to the bottom side of the second dovetail plate 9. As the first dovetail plate 7 inserts into the front dovetail groove, the second dovetail plate 9 will also insert into the rear dovetail groove. After the second dovetail plate 9 is inserted into the rear dovetail groove, the lever 12 is released, allowing the latching plate 11 to insert into the latching groove to fix the inclined plate 10, thereby fixing the second dovetail plate 9 into the rear dovetail groove. This fixes the base plate 1 and the top plate 3 in place. The lever 12 rotates downward under the action of the torsion spring to fold the volume and prevent the lever 12 from being moved due to external force. Then, the guide ring 5 is rotated according to the direction of the wire. After the guide ring 5 has rotated, the second handle 16 is rotated to make the threaded rod 15 rotate, thereby driving the insertion rod 14 to insert into the corresponding slot, so that the rotating seat 2 is fixed, thereby fixing the angle of the guide ring 5. Then, the wire is passed through the guide ring 5 and introduced between the two clamping rings 6. Then, the end of the wire is passed through the other guide ring 5. Then, the first handle 8 is rotated to make the bidirectional screw 4 rotate, so that the two clamping rings 6 slide toward the wire, thereby clamping and fixing the wire, thus completing the fixing of the wire.
[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
