Description

Technical Field

[0001] This utility model relates to the technical field of alloy torque clamp-type voltage testing grounding clamps, and in particular to an alloy torque clamp-type voltage testing grounding clamp. Background Technology

[0002] With the continuous development of society and the continuous progress of science and technology, the technology related to alloy torque clamp-type voltage testing and grounding clamps is also constantly improving. Alloy torque clamp-type voltage testing and grounding clamps are non-load-bearing voltage testing and grounding devices, mainly used in power distribution line systems of 10KV and below, and can play a role in safe voltage testing and grounding operations.

[0003] The alloy torque clamp-type grounding clamp currently in use cannot be adjusted to fit the actual conductor thickness, resulting in poor connection with conductors of different thicknesses. This limits its applicability and application, hindering the use of the alloy torque clamp-type grounding clamp. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the existing technology: the alloy torque clamp type voltage tester grounding clamp currently used cannot be adjusted and adapted according to the actual wire thickness, which leads to the inability to make good connection with wires of different thicknesses, resulting in a small range of applications and great limitations in use, which is not conducive to the use of alloy torque clamp type voltage tester grounding clamp. Therefore, an alloy torque clamp type voltage tester grounding clamp is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An alloy torque clamp type grounding clamp includes a base and a grounding component. A fixed clamping block is fixedly installed on the base. A threaded rod is threadedly connected to the base. A movable clamping block is rotatably connected to the lower end of the threaded rod. A limit component is provided on the movable clamping block. Both the fixed clamping block and the movable clamping block are provided with arc-shaped grooves.

[0007] Both sides of the fixed clamping block and the movable clamping block are fixedly connected to sliding plates. Each sliding plate is slidably connected to a slider. Multiple sliders are connected by two telescopic rods. Both the fixed clamping block and the movable clamping block have two symmetrically arranged slots. Each slot is equipped with a rotating component. The rotating component includes a rotating shaft connected to the inner wall of the slot by a torsion spring. A clamping plate and a rotating block are fixedly connected to the rotating shaft. One end of the clamping plate is provided with an arc surface. Each slider is equipped with a pressing component.

[0008] Preferably, each of the extrusion components includes a bending strip fixedly connected to the slider, and the plurality of bending strips are arranged symmetrically.

[0009] Preferably, the limiting component includes a limiting rod fixedly installed on the upper surface of the movable clamping block, and the limiting rod is slidably connected to the base.

[0010] Preferably, a limiting plate is fixedly connected to both of the upper bending strips, and a screw is threaded onto the limiting rod. Each limiting plate has multiple through holes for connecting the screw.

[0011] Preferably, the cross-section of each of the skateboards is arranged in a U-shape, and the cross-section of each of the sliders is arranged in an I-shape.

[0012] Preferably, a concave frame is provided below the base, the concave frame is connected to the base by two bolts, and the grounding member has two round holes for connecting the bolts.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Place the wire in the arc-shaped groove of the fixed clamping block, then rotate the threaded rod. After the wire is in the middle of the two arc-shaped grooves, move the two upper sliders. The two lower sliders move simultaneously and the distance between them decreases. Each bending strip moves against the surface of the corresponding rotating block as it moves. The rotating shaft rotates simultaneously within the slot. The arc surface of each clamping plate will be in close contact with the upper and lower surfaces of the wire, respectively. Under the combined restraint of the fixed clamping block, the moving clamping block, and multiple clamping plates, the wire can be clamped. It can be adjusted and adapted according to the actual wire thickness by changing the tilt angle of each clamping plate so that the clamping plate is in close contact with the surface of wires of different thicknesses. This allows the alloy torque clamp-type voltage testing and grounding clamp to be well connected with wires of different thicknesses, with a wide range of applications and fewer limitations in use, which is beneficial to the use of the alloy torque clamp-type voltage testing and grounding clamp.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0023] Reference Figures 1-5 An alloy torque clamp type grounding clamp includes a base 1 and a grounding component 2. A fixed clamping block 9 is fixedly installed on the base 1, and a threaded rod 5 is threadedly connected to the base 1. A movable clamping block 8 is rotatably connected to the lower end of the threaded rod 5. A limit component is provided on the movable clamping block 8. Both the fixed clamping block 9 and the movable clamping block 8 are provided with arc-shaped grooves. Slide plates 7 are fixedly connected to both sides of the fixed clamping block 9 and the movable clamping block 8. A slider 15 is slidably connected to each slide plate 7. Multiple sliders 15 are connected by two telescopic rods 4. Next, two symmetrically arranged slots are opened on both the fixed clamping block 9 and the movable clamping block 8. Each slot is equipped with a rotating component. The rotating component includes a rotating shaft 11 connected to the inner wall of the slot through a torsion spring 17. A clamping plate 10 and a rotating block 16 are fixedly connected to the rotating shaft 11. One end of the clamping plate 10 is provided with an arc surface. Each slider 15 is equipped with a pressing component. The fixed clamping block 9, the movable clamping block 8 and the multiple clamping plates 10 are all made of high-strength aluminum alloy, which has good electrical conductivity and mechanical strength.

[0024] Each extrusion assembly includes a bent strip 14 fixedly connected to the slider 15. Multiple bent strips 14 are symmetrically arranged. When each bent strip 14 moves, one end of it will abut against the surface of the corresponding rotating block 16, thereby causing the rotating block 16 to rotate. The rotating shaft 11 rotates in the slot at the same time. Since the two ends of the torsion spring 17 are fixedly connected to the inner wall of the slot and the rotating shaft 11 respectively, the torsion spring 17 deforms. The limiting assembly includes a limiting rod 6 fixedly installed on the upper surface of the moving clamping block 8. The limiting rod 6 is slidably connected to the base 1. The lower end of the threaded rod 5 is rotatably connected to the moving clamping block 8 and cannot be separated. When the threaded rod 5 is rotated, during the process of the threaded connection between the threaded rod 5 and the base 1, it will also rotate relative to the moving clamping block 8. The moving clamping block 8 will move along the threaded rod 5.

[0025] Limiting plates 13 are fixedly connected to the two upper bending strips 14. Screws 12 are threaded onto the limiting rods 6. Each limiting plate 13 has multiple through holes for connecting screws 12. When the two upper sliders 15 are moved and the distance between them is reduced, the two lower sliders 15 move simultaneously and the distance between them decreases under the transmission action of the two telescopic rods 4. When each bending strip 14 moves, one end of it will abut against the surface of the corresponding rotating block 16, causing the rotating block 16 to rotate. The rotating shaft 11 rotates in the slot at the same time, and the torsion spring 17 deforms. When the arc surface of each clamping plate 10 is in close contact with the upper and lower surfaces of the wire respectively, the two staggered limiting plates 13 will have overlapping through holes. One end of the screw 12 passes through the two overlapping through holes and is threaded onto the limiting rod 6, which can effectively prevent the rotating shafts 11, rotating blocks 16 and clamping plates 10 from rotating arbitrarily.

[0026] Each slide plate 7 has a U-shaped cross-section, and each slider 15 has an I-shaped cross-section. The I-shaped slider 15 slides on the U-shaped slide plate 7. The slider 15 can only move along the slide plate 7 and cannot detach from it. A concave frame 3 is provided below the base 1. The concave frame 3 is connected to the base 1 by two bolts. The grounding component 2 has two round holes for connecting bolts. The concave frame 3 is fitted onto the outside of the grounding component 2. Then, one end of each T-shaped bolt passes through the concave frame 3 and the round holes on the grounding component 2 and is threaded to the base 1, thus firmly connecting the grounding component 2 to the base 1. The grounding component 2 is a rectangular grounding ring with an insulating layer on both sides. The insulating layer can insulate the part of the grounding ring connected to the wire, ensuring safety during use.

[0027] In this invention, during installation, the wire is first placed in the arc-shaped groove of the fixed clamping block 9, ensuring that the wire is in contact with the lowest surface of the arc-shaped groove. Then, the threaded rod 5 is rotated. During the threaded connection between the threaded rod 5 and the base 1, it also rotates relative to the movable clamping block 8. The movable clamping block 8 moves downward along the threaded rod 5, and the limiting rod 6 simultaneously slides relative to the base 1 until the surface of the arc-shaped groove on the movable clamping block 8 is in contact with the upper part of the wire surface. At this point, the highest surface of the arc-shaped groove is in contact with the highest surface of the wire, meaning the wire is located precisely in the middle of the two arc-shaped grooves. Then, the two upper sliders 15 are moved to reduce the distance between them. Since the two ends of each telescopic rod 4 are fixedly connected to the corresponding upper and lower sliders 15, the two lower sliders 15 move simultaneously and the distance between them decreases under the transmission action of the telescopic rod 4. When each bent strip 14 moves, one end of it will abut against the surface of the corresponding rotating block 16, thereby causing the rotating block 16 to rotate. The rotating shaft 11 rotates in the slot at the same time. Since the two ends of the torsion spring 17 are fixedly connected to the inner wall of the slot and the rotating shaft 11 respectively, the torsion spring 17 deforms.

[0028] Each clamping plate 10 changes from a horizontal state to an inclined state. The arc surface of each clamping plate 10 will be in close contact with the upper and lower surfaces of the conductor, respectively. During this process, the clamping plates 10 will not come into contact. Under the combined restraint of the fixed clamping block 9, the movable clamping block 8, and the multiple clamping plates 10, the conductor can be clamped. It can also be adjusted and adapted according to the actual thickness of the conductor, that is, the inclination angle of each clamping plate 10 is changed so that the clamping plate 10 is in close contact with the surface of conductors of different thicknesses. This allows the alloy torque clamp-type voltage testing and grounding clamp to be well connected with conductors of different thicknesses, with a wide range of applications and fewer limitations in use, which is beneficial to the use of the alloy torque clamp-type voltage testing and grounding clamp.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
