Description

Technical Field

[0001] This utility model relates to the field of electric heat tracing technology, specifically a self-fixing electric heat tracing cable. Background Technology

[0002] Electric heating tape is a cable consisting of a conductive polymer, two parallel metal conductors, and an insulating sheath. It has a wide range of applications, mainly for pipeline insulation and antifreeze solutions. It can be used in low-temperature environments to ensure that pipelines do not freeze in cold seasons.

[0003] The prior art, disclosed in patent document CN221784368U, presents the following technical solution: a self-fixing electric heating tape, specifically relating to the field of electric heating tape technology, comprising an electric heating tape body, a first mounting frame disposed on the surface of the electric heating tape body, a second mounting frame disposed on the rear side of the first mounting frame, a magnet block mounted on the surface of the first mounting frame, and mounting structures disposed at the top and bottom of the first mounting frame, the mounting structures comprising a first sleeve and a second sleeve, wherein the first sleeve is fixedly mounted on the top of the first mounting frame, and the second sleeve is fixedly mounted on the bottom of the first mounting frame, and movable blocks are slidably disposed inside both the first sleeve and the second sleeve.

[0004] The above technical solution uses the stretching of the elastic fixing rope to fix it to the outside of the pipe. However, in winter, the temperature is low, and the elastic rope material becomes harder and more brittle, reducing its flexibility and making it easy to break, which affects the fixing effect of the electric heating cable. The use of the elastic fixing rope is limited by the weather. Utility Model Content

[0005] The purpose of this invention is to provide a self-fixing electric heating cable to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a self-fixing electric heating cable, comprising an electric heating cable body, an upper mounting frame provided on the upper surface of the electric heating cable body, a lower mounting frame provided on the lower surface of the electric heating cable body, the upper mounting frame and the lower mounting frame being connected by screws, and an electric heating cable fixing structure being fixedly installed at the bottom of the lower mounting frame.

[0007] The electric heating cable fixing structure includes an upper retaining ring, one end of which is movably connected to a lower retaining ring via a connector. Both the upper and lower retaining rings are fixedly connected to mounting plates at their other ends. A positioning groove is provided on the bottom side of the upper mounting plate, and through holes are provided at both ends of the positioning groove. Annular plates are installed on the front and rear outer surfaces of the upper mounting plate via screws. A spring is embedded in the outer side of each annular plate, and a pull plate is embedded in the other side of each spring. A limit rod is fixedly connected to the center of each pull plate, and the limit rod is located inside the spring. Clamping components are arranged circumferentially between the upper and lower retaining rings.

[0008] In the above technical solution, the electric heating cable can be attached to the pipeline by the upper and lower retaining rings, and the limiting rod can be locked in the limiting hole of the positioning block by the elastic action of the spring. The upper and lower retaining rings can be fixed, disassembled easily, and the position installed on the pipeline can be adjusted.

[0009] As a further preferred embodiment of this technical solution, anti-slip grooves are provided on the opposite sides of both mounting plates.

[0010] In the above technical solution, the anti-slip groove allows workers to easily fix the upper and lower mounting plates by hand when clamping the upper and lower retaining rings, preventing slippage that would affect the engagement of the upper and lower retaining rings.

[0011] As a further preferred embodiment of this technical solution, a positioning block is fixedly connected to the mounting plate described below. Limiting holes are provided on both the front and rear sides of the positioning block, and the positioning block is engaged inside the positioning groove.

[0012] In the above technical solution, the opening and closing upper and lower retaining rings are positioned by positioning grooves and positioning blocks.

[0013] As a further preferred embodiment of this technical solution, the limiting hole is aligned with the through hole, and the limiting rod extends through the through hole into the interior of the limiting hole.

[0014] As a further preferred embodiment of this technical solution, the clamping assembly includes a mounting box, which is disposed in the grooves inside the upper and lower retaining rings. A second spring is embedded inside each mounting box, and a limiting plate is embedded at the other end of each second spring. The outer wall of the limiting plate is slidably connected to the inner wall of the mounting box.

[0015] As a further preferred embodiment of this technical solution, each of the limiting plates is fixedly connected to a connecting plate on its outer side, and each of the connecting plates is fixedly connected to an arc-shaped clamping plate on its other end.

[0016] In the above technical solution, when the upper and lower retaining rings are fixed on the pipe, the arc-shaped clamping plate, through the limiting plate and connecting plate, causes the spring to compress and deform, thereby making the anti-slip rubber pad fit more tightly against the outer wall of the pipe.

[0017] As a further preferred embodiment of this technical solution, anti-slip pads are fixedly connected to the outer side of each of the arc-shaped clamps, and the anti-slip pads are pressed into contact with the outer wall of the pipe by the elasticity of the second spring.

[0018] The anti-slip rubber pads in the above technical solution can improve the effect of fixing the electric heating cable to the pipe.

[0019] This utility model provides a self-fixing electric heat tracing cable, which has the following beneficial effects:

[0020] (1) This utility model, through the installation of the electric heat tracing cable fixing structure, can attach the electric heat tracing cable to the pipe through the set upper and lower retaining rings. The opening and closing upper and lower retaining rings are positioned by the positioning groove and positioning block, and the limiting rod is locked in the limiting hole of the positioning block by the elastic action of the spring, which can fix the upper and lower retaining rings. It is easy to disassemble and easy to open and adjust the position of the cable installed on the pipe. Compared with the fixing by pulling the elastic rope in the prior art, it is more secure and not limited by the external environment.

[0021] (2) By setting the clamping component, when the upper and lower clamping rings are fixed on the pipe, the arc-shaped clamping plate compresses and deforms the spring through the limiting plate and connecting plate, thereby making the anti-slip rubber pad fit more tightly on the outer wall of the pipe, improving the effect of fixing the electric heating tape on the pipe, and avoiding slippage that affects the installation position.

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] This utility model provides a technical solution: such as Figure 1 As shown in this embodiment, a self-fixing electric heating cable includes an electric heating cable body 1, an upper mounting frame 2 is provided on the upper surface of the electric heating cable body 1, and a lower mounting frame 3 is provided on the lower surface of the electric heating cable body 1. The upper mounting frame 2 and the lower mounting frame 3 are connected by screws. The mounting frame is detachable, which makes it easy to disassemble and remove the electric heating cable fixing structure 4. The electric heating cable fixing structure 4 is fixedly installed at the bottom of the lower mounting frame 3.

[0029] like Figure 2 and Figure 4 As shown, the electric heating cable fixing structure 4 includes an upper retaining ring 41. One end of the upper retaining ring 41 is movably connected to a lower retaining ring 42 via a connector. Mounting plates 43 are fixedly connected to the other ends of both the upper and lower retaining rings 41 and 42. Anti-slip grooves 431 are provided on opposite sides of the two mounting plates 43. These grooves facilitate the operator's gripping of the mounting plates 43 by hand when tightening the two retaining rings, preventing slippage and ensuring the retaining rings are properly engaged. A positioning groove 432 is provided on the bottom side of the upper mounting plate 43. Through holes 433 are provided at both ends of the positioning groove 432. Ring plates 44 are screwed onto the front and rear outer surfaces of the upper mounting plate 43. Springs 45 are embedded in the outer sides of the ring plates 44, and pull plates 46 are embedded in the other side of each spring 45. Limiting rods 47 are fixedly connected to the middle of each pull plate 46, located inside the springs 45. The lower mounting plate 4... A positioning block 434 is fixedly connected to the top of the 3rd section. The positioning block 434 has limit holes 435 on both its front and rear sides. The positioning block 434 is engaged inside the positioning groove 432. The limit holes 435 are aligned with the through holes 433. The limit rod 47 extends through the through holes 433 into the limit hole 435. By installing the electric heating cable fixing structure 4, the electric heating cable can be attached to the pipe using the upper retaining ring 41 and the lower retaining ring 42. The opening and closing upper retaining ring 41 and the lower retaining ring 42 are positioned by the positioning groove 432 and the positioning block 434. The elasticity of the spring 45 causes the limit rod 47 to be engaged in the limit hole 435 of the positioning block 434, thus fixing the upper retaining ring 41 and the lower retaining ring 42. This allows for easy disassembly and adjustment of the installation position on the pipe. Compared to the fixing method using elastic ropes in the comparative document, this method is more secure and not limited by external environmental conditions.

[0030] like Figure 2 and Figure 3As shown, clamping components 48 are arranged circumferentially between the upper retaining ring 41 and the lower retaining ring 42. Each clamping component 48 includes a mounting box 481, which is located within a groove on the inner side of both the upper and lower retaining rings 41 and 42. A second spring 482 is embedded inside each mounting box 481, and a limiting plate 483 is embedded at the other end of each spring 482. The outer wall of the limiting plate 483 is slidably connected to the inner wall of the mounting box 481. A connecting plate 484 is fixedly connected to the outer side of each limiting plate 483, and an arc-shaped clamping plate 485 is fixedly connected to the other end of each connecting plate 484. Anti-slip pads 486 are fixedly connected to the outer side of the clamping plate 485. The anti-slip pads 486 are made of silicone. The anti-slip pads 486 are pressed against the outer wall of the pipe by the elasticity of the second spring 482. The clamping component 48 is provided so that when the upper clamping ring 41 and the lower clamping ring 42 are fixed on the pipe, the arc-shaped clamping plate 485 compresses and deforms the second spring 482 through the limiting plate 483 and the connecting plate 484, thereby making the anti-slip pads 486 fit more tightly against the outer wall of the pipe, improving the effect of fixing the electric heating cable on the pipe and avoiding slippage that would affect the installation position.

[0031] This utility model provides a self-fixing electric heating cable. The specific working principle is as follows: After the electric heating cable body 1 is laid on the pipe, the upper mounting frame 2 and the lower mounting frame 3 are fixed on the electric heating cable body 1 according to the required fixed position. Then, the upper retaining ring 41 and the lower retaining ring 42 are opened to fix the pipe. After that, the upper retaining ring 41 and the lower retaining ring 42 are closed. The operator pulls the pull plates 46 at both ends, so that the limiting rod 47 is pulled outward, and at the same time, the spring 45 is pulled until it is positioned by the positioning block 434 and the positioning groove 432. The operator releases his hand, and the spring 45 returns to its original position, so that the limiting rod 47 is inserted into the limiting hole 435. After the pipe is fixed, the electric heating cable is pressed tightly between the pipe and the anti-slip pad 486 by squeezing the arc-shaped clamp 485. The spring 482 returns to its original position, so that the electric heating cable is in contact with the pipe, and the other anti-slip pads 486 can be in close contact with the outer wall of the pipe.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
