Description

Technical Field

[0001] The present invention relates to the technical field of safety detection of power equipment, and particularly relates to a grounding device for a JP cabinet. Background Art

[0002] With the rapid development of China's power grid construction, the power grid facilities of local power supply enterprises have been continuously improved. With the continuous deepening of the rural power grid transformation, a large number of JP cabinets have been applied to rural power lines and various distribution areas. The JP cabinet is a comprehensive distribution transformer cabinet designed to meet the requirements of standardization, miniaturization, and outdoor use of rural low-voltage distribution devices. It integrates power distribution, metering, protection, and capacitor reactive power compensation. However, due to the small volume of the existing JP cabinet and the small spacing between the internal components of the cabinet, when using a spring clamp-type grounding wire to connect to the grounding end of the JP cabinet, a stable connection cannot be achieved, and the phenomenon of the grounding wire clamp falling off easily occurs. This will not only affect the normal use of the JP cabinet, but also damage the components inside the cabinet. Even more seriously, it will cause the JP cabinet to malfunction and affect the normal power consumption of residents. Therefore, it is very necessary to provide a JP cabinet grounding device with good clamping effect, stable and reasonable structure, small occupied volume, and good grounding effect. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a JP cabinet grounding device with good clamping effect, stable and reasonable structure, small occupied volume, and good grounding effect.

[0004] The purpose of the present invention is achieved as follows: The JP cabinet grounding device includes fixed arms. The number of the fixed arms is two, and the fixed clamping port is between the two fixed arms. A triangular bracket is provided on the fixed arm. The triangular bracket passes through the fixed arm through an annular hole. A grounding port is also provided on the fixed arm. An articulated plate is provided at the lower part of the fixed arm. The number of the articulated plates is two. An articulated block is articulated between the two articulated plates through an articulated shaft. A movable handle is fixedly provided on the outer side of the articulated block. A hollow cylindrical rotating sleeve is provided outside the movable handle. The inner wall of the rotating sleeve is fixedly connected to a rotating shaft through a connecting rod. The rotating shaft is rotatably arranged inside the movable handle. The other end of the rotating shaft is arranged inside the articulated block. A gear is provided on the rotating shaft. The gear meshes with a rack. Both the gear and the rack are arranged inside the articulated block. The lower part of the rack corresponds to a limiting groove on the connecting plate. A pull plate is provided on the inner side of the articulated block. The pull plate is arranged in a pull plate movable hole on the fixed arm. The pull plate movable hole and the annular hole are vertically arranged. A turning portion is provided in the middle of the pull plate. A pull plate hole is provided on the pull plate in front of the turning portion. The triangular bracket passes through the pull plate hole.

[0005] There are two triangular brackets, which are respectively arranged on two fixed arms. The triangular bracket is composed of three support rods and connecting frames at both ends. The connecting frames at both ends of the triangular bracket are respectively located on both sides of the fixed arms. The three support rods are all arranged through the fixed arms and the pull plates, and the structures of the two fixed arms are consistent.

[0006] The pull plate is a rectangular structure, the turning part in the middle of the pull plate is inclined upward, the lower pull plate and the upper pull plate are symmetrically arranged, the pull plate movable hole is consistent with the pull plate structure, and a turning part is also arranged.

[0007] The tripod bracket and the fixed arm are both made of conductive metal, such as aluminum alloy or copper metal.

[0008] The inner wall of the pull plate hole is provided with pull plate limiting teeth, and the three support rods of the triangular bracket are provided with triangular bracket limiting teeth, and the pull plate limiting teeth match the triangular bracket limiting teeth.

[0009] The limiting groove is arranged on the hinged plate at the lower side, and the limiting groove is hemispherical, corresponding to the hemispherical shape of the lower part of the rack.

[0010] The beneficial effects of the present invention are as follows: the present invention uses a triangular bracket to contact a grounding terminal or a JP cabinet, and the movable handle rotates, driving the hinge block to rotate, and at the same time driving the pull plate to move outward. A turning part is provided on the pull plate, and the turning part squeezes the two pull plates together, thereby driving the triangular bracket to move inward. Moreover, since a pull plate limiting tooth is provided in the pull plate hole and a triangular bracket limiting tooth is provided on the triangular bracket, the fixation of the triangular bracket is more stable and plays a role of fine-tuning. Moreover, the movable handle can be fixed at the hinge plate by rotating the rotating sleeve to complete the clamping of the grounding terminal or the JP cabinet. The present invention has the advantages of good clamping effect, stable and reasonable structure, small occupied volume and good grounding effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Embodiment 1

[0020] As Figure 1-6 shown, the grounding device of the JP cabinet includes a fixed arm 1. The number of the fixed arms 1 is two. There is a fixed clamping mouth 5 between the two fixed arms. A triangular bracket 2 is arranged on the fixed arm 1. The triangular bracket 2 penetrates through the fixed arm 1 through an annular hole 3. A grounding port 4 is also arranged on the fixed arm 1. A hinge plate 6 is arranged at the lower part of the fixed arm 1. The number of the hinge plates 6 is two. A hinge block 8 is hinged between the two hinge plates 6 through a hinge shaft 7. A movable handle 9 is fixedly arranged on the outer side of the hinge block 8. A hollow cylindrical rotating sleeve 10 is arranged outside the movable handle 9. The inner wall of the rotating sleeve 10 is fixedly connected with a rotating shaft 18 through a connecting rod 17. The rotating shaft 18 is rotatably arranged inside the movable handle 9. The other end of the rotating shaft 18 is arranged inside the hinge block 8. A gear is arranged on the rotating shaft 18. The gear meshes with a rack 19. The gear and the rack 19 are both arranged inside the hinge block 8. The lower part of the rack 19 corresponds to a limiting groove 20 on the hinge plate 6. A pulling plate 12 is arranged on the inner side of the hinge block 8. The pulling plate 12 is arranged in a pulling plate movable hole 11 of the fixed arm 1. The pulling plate movable hole 11 and the annular hole 3 are vertically arranged. A turning part 13 is arranged in the middle of the pulling plate 12. A pulling plate hole 14 is arranged on the pulling plate 12 in front of the turning part 13. The triangular bracket 2 passes through the pulling plate hole 14.

[0021] When in use, first place the fixed clamp 5 at the grounding end that needs to be grounded, lightly press the upper and lower triangular brackets 2 with your fingers to ensure that the upper and lower triangular brackets 2 are in contact with the grounding end, and then rotate the movable handle 9. The movable handle 9 drives the pull plate 12 to move outward, and the triangular bracket 2 will move downward under the extrusion of the turning part 13. At the same time, the triangular bracket 2 is clamped by the pull plate limiting teeth 16 and the triangular bracket limiting teeth 15, which can keep the triangular bracket 2 stably squeezed downward. When the clamping degree is appropriate, rotate the rotating sleeve 10 to make the rack 19 move downward, thereby clamping the limiting groove 20. The movable handle 9 is fixed, and the triangular bracket 2 can also be clamped more tightly with the grounding end. The grounding port 4 on the fixed arm 1 is used to connect the grounding wire to complete the grounding of the JP cabinet.

[0022] The present invention uses a triangular bracket 2 to contact a grounding terminal or a JP cabinet, and the movable handle 9 rotates, driving the hinge block 8 to rotate, and at the same time driving the pull plate 12 to move outward. The pull plate 12 is provided with a turning part 13, and the turning part 13 squeezes the two pull plates 12 to move together, thereby driving the triangular bracket 2 to move inward. In addition, since a pull plate limiting tooth 16 is provided in the pull plate hole 14, and a triangular bracket limiting tooth 15 is provided on the triangular bracket 2, the triangular bracket 2 is fixed more stably and plays a role of fine adjustment. In addition, the movable handle 9 can be fixed at the hinge plate 6 by rotating the rotating sleeve 10 to complete the clamping of the grounding terminal or the JP cabinet. The present invention has the advantages of good clamping effect, stable and reasonable structure, small occupied volume, and good grounding effect.

An articulated block 8 is articulated between the two articulated plates 6 through an articulated shaft 7. An activity handle 9 is fixedly arranged on the outer side of the articulated block 8. A hollow columnar rotating sleeve 10 is arranged outside the activity handle 9. The inner wall of the rotating sleeve 10 is fixedly connected with a rotating shaft 18 through a connecting rod 17. The rotating shaft 18 is rotatably arranged inside the activity handle 9. The other end of the rotating shaft 18 is arranged inside the articulated block 8. A gear is arranged on the rotating shaft 18. The gear meshes with a rack 19. Both the gear and the rack 19 are arranged inside the articulated block 8. The lower part of the rack 19 corresponds to a limit groove 20 on the articulated plate 6. A pull plate 12 is arranged on the inner side of the articulated block 8. The pull plate 12 is arranged in a pull plate moving hole 11 of the fixed arm 1. The pull plate moving hole 11 and the annular hole 3 are vertically arranged. A turning part 13 is arranged in the middle of the pull plate 12. A pull plate hole 14 is arranged on the pull plate 12 in front of the turning part 13. The triangular bracket 2 passes through the pull plate hole 14.

[0025] The number of the triangular brackets 2 is two, which are respectively arranged on the two fixed arms 1. The triangular bracket 2 is composed of three support rods and two end connecting frames. The two end connecting frames of the triangular bracket 2 are respectively located on both sides of the fixed arm 1. All three support rods pass through the fixed arm 1 and the pull plate 12. The structures of the two fixed arms 1 are the same. The pull plate 12 is of a cuboid structure. The turning part 13 in the middle of the pull plate 12 is inclined upward. The lower pull plate 12 and the upper pull plate 12 are symmetrically arranged. The pull plate moving hole 11 has the same structure as the pull plate and also has a turning part 13.

The limit groove 20 is hemispherical and corresponds to the hemispherical shape at the lower part of the rack 19.

[0026] The present invention is achieved by using the triangular bracket 2 to contact the grounding terminal or the JP cabinet body. When the movable handle 9 rotates, it drives the articulated block 8 to rotate, and at the same time drives the pull plate 12 to move outward. A turning portion 13 is provided on the pull plate 12, and the turning portion 13 squeezes the two pull plates 12 to move closer together, thereby driving the triangular bracket 2 to move closer inward. And because there are pull plate limiting teeth 16 provided in the pull plate hole 14 and triangular bracket limiting teeth 15 provided on the triangular bracket 2, the triangular bracket 2 can be fixed more stably, playing a role in fine adjustment. Moreover, the movable handle 9 can be fixed at the articulated plate 6 by rotating the rotating sleeve 10 to complete the clamping of the grounding end or the JP cabinet body. The present invention has the advantages of good clamping effect, stable and reasonable structure, small occupied volume, and good grounding effect.
