Description

Technical Field

[0001] This utility model belongs to the field of cable application technology, specifically relating to a cable fixing device for electrical engineering. Background Technology

[0002] With social development and technological progress, people's lives have gradually improved, and electricity is ubiquitous in people's lives. The medium for transmitting electricity is mostly cables, which have the characteristics of being internally energized and externally insulated. Currently, in power construction, cables are generally fixed by fixing devices.

[0003] Some electrical cable fixing devices are typically single-layer structures. When this type of structure is used to fix electrical cables, if there is not enough space parallel to the surface of the equipment to fix the cables, it is impossible to use the space perpendicular to the surface of the equipment for fixing operations. The applicable scope is relatively small. When multiple cables need to be fixed, the connection cables between the equipment and the power supply are easily dragged haphazardly. Existing fixing devices are not convenient for neatly arranging cables or fixing the position of cables. At the same time, existing mounting boxes are not convenient for connecting and fixing to the wall, which reduces the practicality of the mounting box. Utility Model Content

[0004] This utility model provides a cable fixing device for electrical engineering to solve the problems of existing fixing devices being inconvenient to fix, cables being misaligned on the fixing device, and cables being easy to fall off.

[0005] The technical solution of this utility model is: a cable fixing device for electrical engineering, including a mounting box, which has multiple fixing holes, and fixing components are installed in the fixing holes; the fixing components include a support ring, a support sleeve, and a mounting cylinder, one end of the mounting cylinder has a slot, the other end of the mounting cylinder is closed, the side of the slot has symmetrical movable grooves, and the movable grooves communicate with the slot; there are two support sleeves, which are semi-cylindrical, and the two support sleeves are fastened to the outside of the mounting cylinder, and one end of the support sleeve has a boss; the support ring is sleeved on the outside of the support sleeve, and the boss and one end of the support ring are connected by bolts.

[0006] As a further improvement of this utility model, a fixing box is installed on one side of the mounting box. The fixing box is equipped with two fixing gears, and a fixing rod is provided on the fixing gears. A fixing rack meshes between the two fixing gears, and one end of the fixing rack is fixedly connected to the mounting box.

[0007] As a further improvement of this utility model, the fixing box is connected by a screw thread, and one end of the screw thread is provided with a clamping pad, which abuts against the fixing rack.

[0008] As a further improvement of this utility model, the opposite surfaces of the two support sleeves are provided with multiple insertion rods and multiple insertion holes, and the insertion rods are inserted into the insertion holes one by one.

[0009] As a further improvement of this utility model, the inner wall of the support sleeve is provided with multiple limiting grooves, and the outer surface of the mounting cylinder is provided with multiple frustums, which are inserted into the limiting grooves one by one.

[0010] As a further improvement of this utility model, the mounting cylinder is provided with multiple protrusions, which help to dissipate heat when the cable is connected to the fixing box.

[0011] As a further improvement of this utility model, the support sleeve is provided with a handle to facilitate cable disassembly.

[0012] The beneficial effects of this utility model are as follows: The fixing components inside the mounting box allow for neat cable arrangement, securing cables of different diameters within the box and improving cable stability. Furthermore, the combination of a fixing rack and pinion ensures a tight fit between the mounting box and the fixing unit, facilitating installation in wall grooves.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1-4 As shown, an electrical engineering cable fixing device includes a mounting box 1 with multiple fixing holes 6, in which fixing components are installed. The fixing components include a support ring 7, a support sleeve 8, and a mounting cylinder 9. One end of the mounting cylinder 9 has a slot 10, and the other end of the mounting cylinder 9 is closed. The slot 10 has symmetrical movable grooves 11 on its side, and the movable grooves 11 communicate with the slot 10. There are two support sleeves 8, which are semi-cylindrical. The two support sleeves 8 are fastened to the outside of the mounting cylinder 9, and one end of the support sleeve 8 has a boss 17. The support ring 7 is sleeved on the outside of the support sleeve 8, and the boss 17 and one end of the support ring 7 are connected by bolts 15.

[0020] A fixing box 2 is installed on one side of the mounting box 1. The fixing box 2 has two fixing gears 3 inside. The fixing gears 3 have fixing rods 4. A fixing rack 5 meshes between the two fixing gears 3. One end of the fixing rack 5 is fixedly connected to the mounting box 1.

[0021] The mounting box 2 is connected by a threaded screw 25. One end of the mounting screw 25 is provided with a clamping pad 26, which abuts against the fixing rack 5.

[0022] The two support sleeves 8 have multiple insertion rods 18 and multiple insertion holes 19 on their opposite sides, and the insertion rods 18 are inserted into the insertion holes 19 one by one.

[0023] The inner wall of the support sleeve 8 is provided with multiple limiting grooves 13, and the outer surface of the mounting cylinder 9 is provided with multiple frustums 12, which are inserted into the limiting grooves 13 in a corresponding manner.

[0024] The mounting cylinder 9 has multiple protrusions 28 inside, which help to dissipate heat when the cable is connected to the mounting box.

[0025] The support sleeve 8 is equipped with a handle 20.

[0026] In use, when installing the cable on the mounting box 1, insert the insertion rod 18 of one side of the support sleeve 8 into the insertion hole 19 of the other side of the support sleeve 8, and fix the support sleeve 8 to the support ring 7 with bolts 15. Pass the cable through the mounting cylinder 9, which is frustum-shaped and made of rubber. Then insert the mounting cylinder 9 into the support sleeve 8. As the mounting cylinder 9 goes deeper, the support sleeve 8 squeezes the mounting cylinder 9, causing the side of the mounting cylinder 9 with the larger radius to squeeze into the movable groove 11, which also squeezes the cable. After the cable is tightly connected to the mounting cylinder 9, the position of the mounting cylinder 9 and the support sleeve 8 is fixed by the cooperation of the frustum 12 and the limiting groove 13, completing the installation and fixing of the cable. When disassembly is required, loosen the bolts 15, remove the support sleeve 8 through the handle 20, separate the two support sleeves 8, and then remove the mounting cylinder 9, which is in contact with the squeezing action of the mounting cylinder 9 on the cable.

[0027] When mounting box 1 is installed on the wall, it is pulled away from the fixed box 2. The mounting box 1 causes the limiting rod 22 to move within the limiting sleeve 21 and compresses the limiting spring 24 through the limiting plate 23. At the same time, the mounting box 1 causes the fixed rack 5 to move outward, causing the two fixed gears 3 to rotate. The two fixed rods 4 move closer to the fixed rack 5 and insert into the groove of the wall. The mounting box 1 is then released. Under the elastic force of the limiting spring 24, the mounting box 1 moves closer to the fixed box 2, thereby causing the fixed rack 5 to move inward and the fixed gears 3 to rotate. This causes the fixed rods 4 to extend to the upper and lower sides and engage with the groove of the wall. Through the limiting spring 24, the fixed rack 5 has a tendency to move inward, which in turn causes the fixed rods 4 to have a tendency to be tensioned to both sides, making the connection of the fixed box 2 stable. At the same time, the mounting knob 27 is rotated, which causes the mounting screw 25 to rotate, causing the clamping pad 26 to press the fixed rack 5, thereby further fixing the position of the fixed rack 5.
