[0019] The technical effects and advantages of this utility model are:

[0020] 1. By setting up a fixing mechanism, compared with the existing technology, when multiple groups of cables inside the device need to be fixed, the cables are first placed between the arc-shaped clamping blocks, and then the two torsion blocks are rotated at the same time to rotate the two rotating rods, thereby rotating the multiple threaded sleeves with opposite threads. The rotation of the threaded sleeves drives the two sliders of the multiple fixing components to move toward each other with the assistance of the slide groove. The opposite movement of the sliders ultimately drives the two arc-shaped clamping blocks to clamp the cables.

[0023] When the cable vibrates under high load, the impact force generated by the cable body is released by the first spring, the second spring, the first telescopic column, and the sliding cylinder. This can prevent the long-term vibration of the cable from causing the insulation layer of the cable to be stressed for a long time and causing it to age too quickly, thereby extending the service life of the cable.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] As attached Figure 1-8 The electrical engineering cable protection device shown includes a housing 1, three sets of fixing mechanisms are provided inside the housing 1, and buffer mechanisms are provided on both sides of the three sets of fixing mechanisms. A base 2 is provided at the bottom of the housing 1, and a sliding cover 3 is slidably provided inside the housing 1;

[0035] Each set of the fixing mechanism includes two fixing components, each of which includes two slide grooves 4 opened on the surface of the base 2 and a rotating rod 6 rotatably connected to both sides of the inner wall of the shell 1;

[0036] Slide blocks 5 are provided inside the two slide grooves 4, and the slide blocks 5 are slidably connected to the slide grooves 4. Corresponding arc-shaped clamping blocks 7 are provided on the tops of the two slide blocks 5.

[0037] The surface of the rotating rod 6 is provided with three threaded sleeves 8 with opposite threads. The two ends of the threaded sleeve 8 are respectively threadedly connected to the two sliders 5. One end of the rotating rod 6 is provided with a torsion block for twisting the rotating rod 6.

[0038] Three entrances and exits 20 are provided on both sides of the housing 1, and the positions of the entrances and exits 20 correspond to the fixing components and the buffer components;

[0039] A handle 24 is provided on the top of the sliding cover 3;

[0040] Two mounting holes 25 are provided on both sides of the base 2;

[0041] The arc-shaped clamping block 7, the buffer member 12 and the extrusion member 14 are all made of aluminum alloy.

[0042] Through the above operations, multiple groups of cables can be easily fixed at the same time, saving time and effort, preventing the cables from loosening and falling off during use, and ensuring the normal operation of the cables.

[0043] Specifically, the two torsion blocks are rotated at the same time, so that the two rotating rods 6 rotate, thereby causing the multiple threaded sleeves 8 with opposite threads to rotate. The rotation of the threaded sleeves 8 drives the two sliders 5 of the multiple fixed components to move toward each other with the assistance of the slide groove 4. The movement of the sliders 5 towards each other ultimately drives the two arc-shaped clamping blocks 7 to clamp the cables.

[0044] In a specific embodiment, as shown in the attached Figure 1 、 2 As shown in , 5, 6, and 7, each group of the buffer mechanism includes two buffer components;

[0045] Each group of the buffer components includes three sliding cylinders 9 arranged on the top of the base 2 and an extrusion column 10 slidably arranged on the surface of the sliding cover 3. The three sliding cylinders 9 are all plugged with a first telescopic column 11. The tops of the three first telescopic columns 11 are fixedly connected to a buffer 12. The surface of the first telescopic column 11 is movably sleeved with a first spring 13, and the top and bottom of the first spring 13 are respectively fixedly connected to the bottom of the buffer 12 and the top of the sliding cylinder 9;

[0046] The bottom of the extrusion column 10 is fixedly connected to an extrusion piece 14, and the surface of the extrusion column 10 is movably sleeved with a second spring 15. The top and bottom of the second spring 15 are respectively fixedly connected to the bottom of the sliding cover 3 and the bottom of the extrusion piece 14. The extrusion piece 14 corresponds to the buffer piece 12.

[0047] A threaded column 16 is provided on the top of the extrusion column 10. The surface of the threaded column 16 is threadedly connected to a limiting column 17, and the diameter of the limiting column 17 is larger than the diameter of the extrusion column 10.

[0048] The housing 1 has a plurality of fixing openings 21 at both ends, and the sliding cover 3 has an insertion opening 22 at both sides. A fixing rod 23 is inserted into one of the fixing openings 21 , and one end of the fixing rod 23 extends into the insertion opening 22 .

[0049] Through the above operations, you can prevent the long-term vibration of the cable from causing the insulation layer of the cable to age too quickly, thereby extending the service life of the cable.

[0050] Specifically, after the cable is fixed, first slide the sliding cover 3 into the housing 1, adjust the position of the sliding cover 3 inside the housing 1 according to the approximate thickness of the cable, align the insertion openings 22 on both sides of the sliding cover 3 with the fixing openings 21 on the surface of the housing 1, and then insert the fixing rods 23 into the fixing openings 21 and the insertion openings 22 to fix the position of the sliding cover 3;

[0051] At this time, the extrusion member 14 and the buffer member 12 are in contact with the surface of the cable, the first spring 13 and the second spring 15 are compressed, the first telescopic column 11 is squeezed into the interior of the sliding cylinder 9, and the top of the extrusion column 10 is squeezed out from the interior of the sliding cover 3;

[0052] When the cable vibrates under high load, the impact force generated by the cable body is released by the coordinated movement of the first spring 13, the second spring 15, the first telescopic column 11, and the sliding cylinder 9, which can prevent the long-term vibration of the cable from causing the insulation layer of the cable to age too quickly, thereby extending the service life of the cable.

[0053] In a specific embodiment, as shown in the attached Figure 1 、 5 As shown, two upper vents 18 are provided on the surface of the sliding cover 3 , and two lower vents 19 are provided on the surface of the base 2 , and the positions of the upper vents 18 and the lower vents 19 correspond to each other.

[0054] The above operations can prevent excessive temperature from affecting the operation of the cable.

[0055] Specifically, when the cable is working, the heat generated by the cable can be absorbed and dispersed through the arc clamp 7, buffer 12 and extrusion member 14, and the heat inside the shell 1 can be dissipated through the upper vent 18 and the lower vent 19 to prevent excessively high temperature from affecting the operation of the cable.

[0056] Working principle of the utility model: When a cable needs to be fixed, first insert the cable into the housing 1 from the entrance 20 on one side of the housing 1, the cable first passes through a buffer component, then passes through two fixing components, and finally passes through a buffer component, and then passes out from the entrance 20 on the other side of the housing 1;

[0057] Then, fix the position of the cable: rotate the two torsion blocks at the same time, so that the two rotating rods 6 rotate, thereby rotating the multiple threaded sleeves 8 with opposite threads. The rotation of the threaded sleeves 8 drives the two sliders 5 of the multiple fixing components to move toward each other with the assistance of the slide grooves 4. The movement of the sliders 5 towards each other ultimately drives the two arc-shaped clamping blocks 7 to clamp the cable, making the connection between the cables more secure.

[0058] After the cable is fixed, first slide the sliding cover 3 into the housing 1. Adjust the position of the sliding cover 3 inside the housing 1 according to the approximate thickness of the cable. After aligning the insertion openings 22 on both sides of the sliding cover 3 with the fixing openings 21 on the surface of the housing 1, insert the fixing rods 23 into the fixing openings 21 and the insertion openings 22 to fix the position of the sliding cover 3.

[0059] At this time, the extrusion member 14 and the buffer member 12 are in contact with the surface of the cable, the first spring 13 and the second spring 15 are compressed, the first telescopic column 11 is squeezed into the interior of the sliding cylinder 9, and the top of the extrusion column 10 is squeezed out from the interior of the sliding cover 3;

[0060] When the cable vibrates under high load, the impact force generated by the cable body is released by the coordinated movement of the first spring 13, the second spring 15, the first telescopic column 11, and the sliding cylinder 9. This can prevent the long-term vibration of the cable from causing the insulation layer of the cable to be stressed for a long time and thus aging too quickly, thereby extending the service life of the cable.

[0061] When the cable is working, the heat generated by the cable can be absorbed and dispersed through the arc clamp 7, the buffer 12 and the extrusion piece 14, and the heat inside the shell 1 can be dissipated through the upper vent 18 and the lower vent 19 to prevent excessive temperature from affecting the operation of the cable.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
