[0022] The technical solutions in the embodiments of the present utility model are clearly and completely described below in conjunction with the accompanying drawings.

[0023] Embodiment 1

[0024] like Figures 1 to 4 As shown, the utility model provides an adjustable roller structure, including a conductive rod 1, a fixed seat 2 is provided at the end of the conductive rod 1, and roller adjustment structures 3 are provided on the four surfaces of the left, right, front and back of the fixed seat 2, which are convenient for adjusting the distance between the clamping blocks 38 and can clamp conductive rods 1 of different specifications, and a plug interface 21 is provided at the upper end of the fixed seat 2, and a protective sleeve 22 is provided inside the plug interface 21, which is an insulating rubber sleeve, which is sleeved on the outside of the plug end 11, plays a basic fixing role for the plug end 11, plays an insulating role, and prevents the clamping block 38 from forming clamping scars on the plug end 11. The roller adjustment structure 3 includes The present invention comprises two symmetrical adjustment blocks 31, wherein a T-slot 32 is arranged at one end of the adjustment blocks 31 close to each other, and a tooth groove 33 is arranged on the lower surface of the T-slot 32 to limit the movement trajectory of the gear 34. When the gear 35 stops rotating, the tooth groove 33 can limit the position of the gear 34. The tooth groove 33 is adapted to connect the gear 34. A connecting rod 35 is arranged between the gears 34. When the connecting rod 35 is rotated by hand, the gear 34 can be driven to roll forward along the tooth groove 33, thereby driving the ring 36 and the push rod 37 to approach the fixed seat 2. A ring 36 is arranged in the middle of the outer surface of the connecting rod 35. When the connecting rod 35 rotates, the ring 36 will not rotate with it.

[0025] Further, if Figure 4As shown, a push rod 37 is provided at the rear end of the circular ring 36, and the end of the push rod 37 away from the circular ring 36 passes through the inner wall of the fixing seat 2 and is fixedly connected to the clamping block 38. Under the action of the connecting rod 35, the push rod 37 pushes the clamping block 38 into the inside of the fixing seat 2, so that the clamping block 38 gradually clamps the conductive rod 1 in the protective sleeve 22, which can tightly clamp conductive rods 1 of different specifications, and has high applicability. The end of the clamping block 38 away from the push rod 37 abuts against the protective sleeve 22.

[0026] Further, if Figure 2 As shown, the conductive rod 1 is provided with a plug-in end 11 at the lower end, and the plug-in end 11 is inserted into the fixing seat 2 for fixing. The outer surface of the plug-in end 11 is sleeved with a protective sleeve 22, and a positioning groove 12 is provided in the middle of the lower end of the plug-in end 11. The positioning groove 12 is adapted to be connected with a positioning column, and the positioning column is located in the middle of the inner lower surface of the fixing seat 2. The positioning groove 12 and the positioning column are adapted to be connected, so as to prevent the plug-in end 11 from being displaced in position when it is not tightened, and to speed up the assembly.

[0027] Further, if Figure 4 As shown, a warning ring 24 is provided on the outer surface of the protective sleeve 22, and the warning ring 24 is made of transparent rubber. A sealing groove 25 is symmetrically provided on the inner surface of the protective sleeve 22 to provide an installation space for a sealing ring 26. A sealing ring 26 is provided in the sealing groove 25, and the inner surface of the sealing ring 26 abuts against the conductive rod 1. The sealing ring 26 ensures the sealing between the conductive rod 1 and the protective sleeve 22.

[0028] Further, if Figure 3 As shown, an observation hole 27 is provided on the left side of the warning ring 24, and the observation hole 27 is located at the left end of the fixing seat 2. The personnel check the warning ring 24 inside the fixing seat 2 through the observation hole 27 to see if there is any color change. If so, timely processing is required. The inner surface of the warning ring 24 is evenly distributed with penetration holes 28. When water vapor appears between the conductive rod 1 and the protective cover 22, the water vapor further erodes the water-soluble film 29 through the penetration holes 28, and a water-soluble film 29 is provided on the surface of the warning ring 24 near the penetration holes 28. The water-soluble film 29 can be made of polyvinyl alcohol film, which can prevent the water-swelling object 210 and the water-discoloring object 211 from falling into the protective cover 22 under normal conditions, making the function invalid.

[0029] Further, if Figure 4As shown, a water-swelling substance 210 is provided on the periphery of the water-soluble film 29, and a water-discoloring substance 211 is provided on the periphery of the water-swelling substance 210. Both the water-swelling substance 210 and the water-discoloring substance 211 are located in the warning ring 24. When the sealing ring 26 ages and loses its sealing performance, when water vapor passes through the sealing ring 26, it will be absorbed by the water-swelling substance 210. One side of the water-swelling substance 210 expands inwards to fill the gap between the conductive rod 1 and the protective cover 22 to prevent further intrusion of water vapor, and the other side merges with the water-discoloring substance 211 to change the color of the water-discoloring substance 211, so that the staff can find problems through the observation hole 27 during daily inspections and replace them in time.

[0030] Working process: first, insert the plug-in end 11 of the conductive rod 1 into the position of the plug interface 21, so that the plug-in end 11 gradually sleeves the protective sleeve 22, and the positioning groove 12 and the positioning column are adapted to be connected, to prevent the plug-in end 11 from being displaced in the unfastened state, and to speed up the assembly speed; further, the hand can rotate forcefully to drive the gear 34 to roll forward along the tooth groove 33, thereby driving the ring 36 and the push rod 37 to approach the fixed seat 2, and the push rod 37 pushes the clamping block 38 into the fixed seat 2, so that the clamping block 38 gradually clamps the conductive rod 1 in the protective sleeve 22, and can play a role of tightly clamping conductive rods 1 of different specifications, and has high applicability.

[0031] In the description of the present invention, it should be understood that the terms "front and back", "left and right", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the equipment or components referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the utility model.

[0032] Of course, in the present technical solution, those skilled in the art should understand that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0033] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto.
