[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 - Figure 3The utility model provides an embodiment: a shielded wire grounding device for electrical equipment, comprising an outer shell 1, a mounting plate 2 is fixedly connected inside the outer shell 1, a positioning cylinder 3 is fixedly connected to the outer wall of the mounting plate 2, a screw 4 is threadedly connected to the inner wall of the mounting plate 2, a handle 5 is fixedly connected to one end of the screw 4, a rotating block 6 is rotatably connected to the other end of the screw 4, a push block 7 is fixedly connected to the outer wall of the rotating block 6, the outer wall of the push block 7 is slidably connected to the inner wall of the positioning cylinder 3, a clamping block 8 is slidably connected to the inner wall of the positioning cylinder 3, a telescopic rod 9 is fixedly connected to the outer wall of the clamping block 8, a spring 10 is sleeved on the outer wall of the telescopic rod 9, both ends of the spring 10 are fixedly connected to the outer wall of the clamping block 8, a limiting component is arranged on the inner wall of the positioning cylinder 3, and the limiting component includes a limiting block 11, and the outer wall of the limiting block 11 is fixedly connected to the inner wall of the positioning cylinder 3;

[0025] Specifically, first, the shielded wire is placed inside the rubber protective sleeve 12 to protect the shielded wire from being affected by the external environment. Then, the driving handle 5 is operated to drive the screw 4 to rotate inside the mounting plate 2. The rotating action is transmitted to one end of the screw 4, causing it to rotate inside the rotating block 6, causing the push block 7 to slide inside the positioning cylinder 3, and applying pressure to the two clamping blocks 8. Under the action of pressure, the two clamping blocks 8 move relative to each other inside the positioning cylinder 3 to fix or release the shielded wire. In this process, the spring 10 is stretched, and the clamping block 8 slides inside the positioning cylinder 3 and the outer shell 1 to complete the disassembly and assembly of the shielded wire, thereby realizing rapid installation and disassembly of the shielded wire and ensuring the stability and safety of the equipment under various working conditions.

[0026] Reference Figure 1 , Figure 2 and Figure 4 The upper surface of the outer shell 1 is fixedly connected with a support 13, the upper surface of the mounting plate 2 is fixedly connected with a rubber protective sleeve 12, the inner part of the support 13 is rotatably connected with a bracket 14, one end of the bracket 14 is fixedly connected with a protective ring 15, the inner wall of the protective ring 15 is fixedly connected to the outer wall of the rubber protective sleeve 12, and the inner part of the mounting plate 2 is slidably connected with a sealing ring 18, the lower surface of the sealing ring 18 is attached to the upper surface of the outer shell 1, and the inner part of the sealing ring 18 is fixedly connected with a telescopic shaft 16, one end of the telescopic shaft 16 is fixedly connected to the inner wall of the mounting plate 2, and the outer wall of the telescopic shaft 16 is sleeved with a spring 2 17, one end of the spring 2 17 is fixedly connected to the inside of the mounting plate 2, and the other end of the spring 2 17 is fixedly connected to the inner wall of the sealing ring 18;

[0027] Specifically, first, one end of the bracket 14 is fixed to the outer wall of the outer shell 1 through the support 13 to ensure the stability of the bracket 14. The other end of the bracket 14 drives the protective ring 15 to support the shielding wire inside the rubber protective sleeve 12, effectively preventing the shielding wire from bending due to external pressure, ensuring its structural integrity and functional effectiveness. When the mounting plate 2 is installed, the fitting process of the sealing ring 18 and the outer shell 1 will cause the spring 2 17 to begin to shrink. As the spring 2 17 shrinks, a thrust is generated to push the sealing ring 18 to fit more closely to the outer shell 1, thereby forming an effective seal, ensuring that the shielding wire will not be affected by external factors during operation, while ensuring the sealing performance of the equipment and preventing electromagnetic interference and environmental pollution.

[0028] Working principle: When the shielded wire grounding device of electrical equipment is needed, first place the shielded wire inside the rubber protective sleeve 12, and then drive the handle 5 to drive the screw 4 to rotate inside the mounting plate 2, and then make one end of the screw 4 rotate inside the rotating block 6, so that the rotating block 6 drives the push block 7 to slide inside the positioning cylinder 3, thereby applying pressure to the two blocks 8, so that the two blocks 8 move relatively inside the positioning cylinder 3, this process will drive the spring 10 to stretch, and then make the block 8 slide inside the positioning cylinder 3 and the outer shell 1, so as to facilitate the disassembly and assembly of the shielded wire, and then fix one end of the bracket 14 to the outer wall of the outer shell 1 through the support 13, and then drive the protective ring 15 to support the shielded wire inside the rubber protective sleeve 12 through the other end of the bracket 14, so as to achieve the effect of anti-bending, when the mounting plate 2 is installed, the sealing ring 18 will fit with the outer shell 1, and this process will cause the spring 2 17 to shrink, and then the thrust generated by the shrinkage of the spring 2 17 will push the sealing ring 18 to fit tightly with the outer shell 1, so as to achieve the sealing effect.
