Description

Technical Field

[0001] This utility model relates to the field of cable laying, and in particular to a cable fixing device for electrical engineering. Background Technology

[0002] When carrying out electrical engineering construction, a large number of cables need to be laid. During the construction process, the cables need to be fixed at certain locations to ensure the stability of the cables during laying and facilitate the construction.

[0003] Most common cable fixing devices are relatively simple in structure, providing only a frame. In use, the frame is placed over the cable and then secured, thus restricting the cable's movement. However, these simple devices are not adjustable in size, requiring the selection of different models. When dealing with diverse and complex cable fixings, a larger frame is often chosen to cover the cable, only restricting it within a certain range and failing to completely secure it. Furthermore, even if the chosen fixing frame perfectly matches the cable and provides complete fixation, in actual use, because the cable is still being laid, it is frequently necessary to pull it in the laying direction. A perfectly fitted frame will completely fix the cable, preventing fine-tuning and making it inconvenient to use. Additionally, when the frame applies pressure to fix the cable, if the space of the pressure structure is smaller than the cable itself, the excessive pressure may flatten the cable, affecting the internal wiring, causing cable damage, and impacting cable operation, thus affecting the quality of the electrical engineering project. Therefore, there is an urgent need for a cable fixing device for electrical engineering that does not affect cable operation. Utility Model Content

[0010] The beneficial effects of this utility model are:

[0020] The present invention will be further described below with reference to embodiments. The description of the embodiments below is only for the purpose of helping to understand the present invention. It should be noted that, for those skilled in the art, several modifications can be made to the present invention without departing from the principle of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.

[0021] As one embodiment, a cable fixing device for electrical engineering is proposed, such as... Figure 1-5As shown, it includes: a fixed base 1, a fixed frame 2, and a control screw 3; the fixed base 1 provides an installation structure for installing the equipment in a suitable position; the fixed frame 2 is fixed on the fixed base 1, and the control screw 3 is threadedly engaged with the top of the fixed frame 2; the upper end of the control screw 3 is provided with a control handle 4, and the lower end extends into the fixed frame 2 and is rotatably connected to a pressure plate 5, which is slidably connected within the fixed frame 2; a pressure frame 12 is provided below the pressure plate 5, and the pressure frame 12 is slidably connected to the fixed frame 2; a pressure roller 9 is rotatably connected to the bottom of the pressure frame 12, and a support roller 8 is rotatably connected to the bottom of the fixed frame 2, with the pressure roller 9 located above the support roller 8; secondary bolts 6 are rotatably connected to both sides of the fixed frame 2, and a limiting block 7 is fixed to the end of the secondary bolt 6 extending into the fixed frame 2, with the other end of the limiting block 7... One end is rotatably connected to a limiting wheel 10; the side wall of the fixed frame 2 is provided with limiting screws 11, and there are two sets of limiting screws 11, which cooperate with the support roller 8 and the pressure roller 9 respectively; the fixed seat 1 provides the installation structure, and the fixed frame 2 provides the limiting structure. The cable passes through the fixed frame 2. When fixing the cable, the internal limiting structure is adjusted according to the radius of the cable. The secondary bolt 6 is rotated so that the secondary bolt 6 cooperates with the fixed frame 2, and moves the limiting block 7 inward to both ends of the cable target position, thereby limiting both sides of the cable. Then, the control handle 4 is rotated, and the control screw 3 is rotated through the control handle 4 so that the control screw 3 cooperates with the fixed frame 2 and descends along the fixed frame 2, thereby driving the pressure plate 5 to press down and press the cable tightly and fix it.

[0022] like Figure 2-5 As shown, the pressure frame 12 has limit sliders 16 on both sides, and the fixed frame 2 has limit grooves 17 on both sides. The limit sliders 16 are slidably connected in the limit grooves 17. Through the cooperation of the limit sliders 16 and the limit grooves 17, the lifting and lowering of the pressure frame 12 is kept stable. The two ends of the pressure roller 9 are rotatably connected to the opposite surfaces of the limit sliders 16. The side wall of the fixed frame 2 is provided with limiting screws 11, which include an upper screw 18 and a lower screw 19. The upper screw 18 and the limit slider 16 are rotatably connected by threads. One end of the upper screw 18 extends out of the limit slider 16 and is provided with an anti-slip head 20. The lower screw 19 is rotatably connected to the fixed frame 2 outside the support roller 8 by threads. One end of the rod 19 extends out of the fixed frame 2 and is equipped with an anti-slip head 20; the anti-slip head 20 provides an anti-slip effect, further improving the stopping ability; the cable is supported by the support roller 8, and restricted by the limiting wheel 10 contacting both sides of the cable; the pressure roller 9 applies pressure to the cable to fix its position and prevent it from shaking. The support roller 8, the pressure roller 9 and the limiting wheel 10 work together to allow the cable to be pulled, which facilitates subsequent cable laying. After the cable is completely laid, the limiting screw 11 can be controlled to move the cable screw inward and contact the corresponding support roller 8 and pressure roller 9 side ends. By tightening, pressure is applied to stop the support roller 8 and pressure roller 9 from rotating, thereby completely fixing the cable.

[0023] like Figure 2 and Figure 3 As shown, a buffer device is provided between the pressure plate 5 and the pressure frame 12. The buffer device includes a buffer spring 13, a guide rod 14, and a limiting head 15. The bottom of the guide rod 14 is connected to the top of the pressure frame 12. The pressure plate 5 has an opening, and the top of the guide rod 14 extends out of the opening and is provided with a limiting head 15. The diameter of the limiting head 15 is larger than the diameter of the opening. The guide rod 14 is fitted with a buffer spring 13, which is located between the pressure plate 5 and the pressure frame 12. When the pressure plate 5 descends, the buffer spring 13 carries the pressure frame 12 down. When the pressure roller 9 contacts the cable, the reverse force causes the pressure frame 12 to exert force upward. The buffer spring 13 contracts to absorb the pressure, thereby avoiding excessive pressure at the initial contact. This allows the pressure of the pressure roller 9 on the cable to gradually increase to a suitable pressure, preventing the cable from being damaged due to excessive pressure. The sliding between the guide rod 14 and the pressure plate 5 ensures a stable fit between the pressure frame 12 and the pressure plate 5.

[0024] like Figure 4 and Figure 5 As shown, the support roller 8 and the pressure roller 9 are provided with a bonding groove 21, and the diameter of the middle section of the bonding groove 21 is smaller than the diameter of the two ends of the bonding groove 21; the bonding grooves 21 of the support roller 8 and the pressure roller 9 are aligned vertically, and the bonding grooves 21 are covered with bonding pads 22; the support roller 8 and the pressure roller 9 cooperate with the cable through the structure provided by the bonding groove 21 to increase the contact area and improve the restraint effect; the bonding pads 22 contact the cable to further improve the protection effect.
