[0005] Therefore, the utility model provides a high-voltage grounding box. Utility Model Content

[0006] The utility model aims to solve the disadvantage in the prior art that the cables inside the cable tube on the high-voltage grounding box are easily loosened or even broken when pulled by external force, and proposes a high-voltage grounding box.

[0019] Preferably, a spring is sleeved on the surface of the sliding pin, and two ends of the spring are fixedly connected to the positioning block and the connecting block respectively.

[0020] The effect achieved by the above components is: the spring will be compressed between the connecting block and the positioning block. When the cable is no longer subjected to external force, the circular ring will bounce the cable away again, thereby avoiding bending of the cable directly between the clamping block, which may easily cause damage to the cable.

[0023] 2. In the utility model, the cable is passed through the circular ring. When the cable is pulled by external force, the spring will be compressed between the connecting block and the positioning block. When the cable is no longer subjected to external force, the circular ring will bounce the cable open again, thereby avoiding the cable from bending directly between the clamping block, which may easily lead to cable damage.

[0029] Reference Figure 1 As shown, the utility model provides a technical solution: a high-voltage grounding box, comprising a box body 1, the lower surface of the box body 1 is connected with four cable tubes 2, the side walls of the cable tubes 2 are provided with a clamping structure 3, and the side walls of the cable tubes 2 are provided with an anti-bending structure 4.

[0030] The specific arrangement and function of the clamping structure 3 and the anti-bending structure 4 are described in detail below.

[0031] Reference Figure 1-Figure 4 As shown, in this embodiment: the clamping structure 3 includes two fixed plates 31 fixedly connected to the side wall of the cable tube 2, the fixed plate 31 is slidably connected with a slide plate 33 inside, the two slide plates 33 are fixedly connected with a clamp block 32 on the side close to each other, and the fixed plate 31 is internally threaded with a driving rod 34. After the cable is pulled out of the port position of the cable tube 2 for a certain distance, the driving rod 34 is rotated, and the driving rod 34 will push the clamp block 32 to move, wherein the slide plate 33 slides inside the fixed plate 31, which plays a role in limiting the moving direction of the clamp block 32, and improves the stability of the cable by clamping the cable pulled out from the inside of the cable tube 2. The driving rod 34 is rotatably connected to the inside of the clamp block 32, and a limiting groove 37 with a "V"-shaped cross section is provided on the surface of the clamp block 32. The "V"-shaped limiting groove 37 on the clamp block 32 facilitates the limiting work of the cylindrical structure cable.

[0032] The inner wall of the limiting groove 37 is evenly fixedly connected with a plurality of anti-slip strips 38, and the cross section of the anti-slip strips 38 is triangular. By providing the anti-slip strips 38, the resistance of the clamping block 32 when clamping the cable is increased, and the stability of the cable clamping is further improved. A plastic film 35 is fixedly installed at the lower end of the cable tube 2. The plastic film 35 can wrap the cable at the closed position of the cable tube 2, and improve the tightness of the connection between the cable tube 2 and the cable. An elastic rope 36 is fixedly installed at the lower end of the plastic film 35. By providing the elastic rope 36, the elastic rope 36 shrinks on the surface of the cable, and further improves the tightness of the connection between the pipe ends of the cable tube 2, and avoids the phenomenon of moisture at the wiring port.

[0033] Reference Figure 1-Figure 3As shown, specifically, the anti-bending structure 4 includes two positioning blocks 42 fixedly connected to the side wall of the cable tube 2, the positioning blocks 42 are slidably connected with a sliding pin 44, the lower ends of the two sliding pins 44 are fixedly installed with a connecting block 43, the two connecting blocks 43 are fixedly installed with a circular ring 41 on the side close to each other, and the upper end of the sliding pin 44 is fixedly installed with a stopper 46. By setting the anti-bending structure 4, the phenomenon of the cable being directly bent between the clamping block 32 when subjected to external force is avoided, and the service life of the cable is extended to a certain extent. The surface of the sliding pin 44 is covered with a spring 45, and the two ends of the spring 45 are fixedly connected to the positioning block 42 and the connecting block 43 respectively. The spring 45 will be compressed between the connecting block 43 and the positioning block 42. When the cable is no longer subjected to external force, the circular ring 41 will bounce the cable again, thereby avoiding the cable being directly bent between the clamping block 32, which is easy to cause the cable to be damaged.

[0034] Working principle: after the cable is pulled out of the port position of the cable tube 2 for a certain distance, the driving rod 34 is rotated, and the driving rod 34 will push the clamping block 32 to move, wherein the slide plate 33 slides inside the fixed plate 31, which plays a role in limiting the moving direction of the clamping block 32. The "V"-shaped limiting groove 37 on the clamping block 32 facilitates the limiting work of the cylindrical structure cable and improves the stability of clamping the cylindrical structure cable. By clamping the cable pulled out from the inside of the cable tube 2, the stability of the cable is improved. By setting the anti-slip strip 38, the resistance of the clamping block 32 when clamping the cable is increased. , further improving the stability of cable clamping. After the cable is pulled out from the cable tube 2 and the inner side of the plastic film 35, the plastic film 35 can wrap the cable at the closed position of the cable tube 2, thereby improving the tightness of the connection between the cable tube 2 and the cable. By setting the elastic rope 36, the elastic rope 36 shrinks on the surface of the cable, thereby further improving the tightness of the connection between the pipe ends of the cable tube 2 and avoiding the phenomenon of moisture at the wiring port. By setting the clamping structure 3, the clamping and sealing work of the cable at the pipe end of the cable tube 2 is facilitated, thereby improving the safety and stability of the cable use to a certain extent.

[0035] When the cable passes through the circular ring 41, when the cable is pulled by external force, the spring 45 will be compressed between the connecting block 43 and the positioning block 42. When the cable is no longer subjected to external force, the circular ring 41 will bounce the cable again, thereby avoiding the cable from bending directly between the clamping block 32, which may easily cause the cable to be damaged. The sliding pin 44 slides inside the positioning block 42 to limit the moving direction of the circular ring 41. By setting the anti-bending structure 4, the cable is prevented from bending directly between the clamping block 32 when subjected to external force, thereby extending the service life of the cable to a certain extent.
