[0002] The grounding clamp is an auxiliary tool used to ground equipment in power systems. Its main components include a C-shaped clamp and a sliding clamp set inside the C-shaped clamp. The bottom of the C-shaped clamp is manipulated by a long rod to move the sliding clamp up to complete the clamping cooperation with the C-shaped clamp, and then the metal clamp connects the wire to the ground for grounding.
[0003] The L-shaped movable part is flipped over so that the C-clip can be easily inserted into the side of the power connection part. At the same time, the L-shaped movable part is reset by flipping, thereby ensuring that the clamping part has sufficient effective contact area. However, in actual use, the flipping state of the L-shaped movable part cannot be accurately controlled and it is easy to flip excessively. At the same time, the bottom end of the L-shaped movable part is easy to block the up and down travel of the sliding clamp below due to its self-rotation, resulting in the inability to complete the clamping in actual use. Moreover, after the clamping is locked, the power connection part is easy to get stuck on the inner wall of the L-shaped movable part, making it impossible to disengage. For this purpose, a grounding wire clamp for small spaces with a limiting and guiding effect is specially provided. Utility Model Content

[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
[0026] The embodiment of the present application solves the problem that the flipping state of the L-shaped movable part cannot be accurately controlled and is prone to excessive flipping by providing a grounding wire clamp for small spaces with a limiting and guiding effect. At the same time, the bottom end of the L-shaped movable part is prone to blocking the up and down travel of the sliding clamp below due to its self-rotation, resulting in the inability to complete clamping during actual use. Moreover, after the clamp is locked, the electrical connection part is easily stuck on the inner wall of the L-shaped movable part, making it impossible to disengage.
[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.
[0028] The embodiment of the utility model discloses a grounding wire clamp for a small space with a limiting and guiding effect.
[0029] According to the attached Figure 1-5 As shown, it includes a clamping seat 1 and a clip 2 slidably arranged on the inner side of the clamping seat 1. The clamping seat 1 or the clip 2 is connected to the ground wire. In this embodiment, the ground wire is connected by the clip 2. The clip 2 is connected to a driving grip 3 that drives it to slide. The clamping seat 1 includes a clamping support 11 and a rotating clamping plate 12. The inner end surface of the clamping support 11 is L-shaped, and the rotating clamping plate 12 is L-shaped. The middle part of the rotating clamping plate 12 is hinged to the end of the clamping support 11. The rotating clamping plate 12 includes a clamping top plate 121 extending from the hinge to one side, and a clamping top plate 121 extending from the hinge to one side. The driving end 122 extends to the other side, the clamping top plate 121 is perpendicular to the driving end 122, and the inner end surface of the clamping support 11 is recessed with an air avoidance groove 113 that can accommodate the driving end 122. The driving end 122 is provided with a guide portion 123 extending toward the end. When in use, when the driving end 122 flips over and enters the air avoidance groove 113, the guide portion 123 prevents the bottom end of the driving end 122 from blocking the upward movement of the clip 2, resulting in the inability to clamp.
[0030] A locking groove 124 is provided in the middle of the inner side of the rotating clamping plate 12. The locking groove 124 provides a certain gripping effect when the rotating clamping plate 12 contacts the power connection piece, preventing the rotating clamping plate 12 and the power connection piece from sliding out relative to each other, thereby improving the clamping efficiency.
[0031] A first stopper 125 is provided on the back of the rotating clamping plate 12, and a second stopper 116 is provided at the end of the clamping support 11 to match the first stopper 125. The first stopper 125 and the second stopper 116 can engage with each other at a preset angle to limit the turning angle of the rotating clamping plate 12. When the rotating clamping plate 12 turns upward, it is positioned to prevent the rotating clamping plate 12 from excessively turning outward, ensuring that the clamping top plate 121 can be maintained at a preset angle during use, making it convenient to enter from one side of the power connection component and go around to the back of the power connection component.
[0032] A support shaft 115 is provided at the notch of the air avoidance groove 113, and the rotating splint 12 is rotatably connected to the outer surface of the support shaft 115. Damping grooves 118 are evenly distributed on both sides of the inner wall of the air avoidance groove 113 along the circumference of the support shaft 115, and damping protrusions 126 adapted to the damping grooves 118 are provided on both sides of the driving end 122 to prevent the rotating splint 12 from easily flipping over arbitrarily, and to prevent the driving end 122 from flipping outward from the inside of the air avoidance groove 113 and colliding with the clip 2 during the upward movement.
[0033] A driving gripping member 3 is installed at the bottom of the clamping seat 1 , and the driving gripping member 3 is transmission-connected to the clamping piece 2 .
[0034] The clip 2 includes an L-shaped conductive clamp 21 and a wiring connection portion 22 integrally formed on the back of the L-shaped conductive clamp 21. The connection portion 22 is connected to the ground wire. The bottom of the L-shaped conductive clamp 21 is integrally formed with an assembly portion 23. The wiring connection portion 22 is used to install the ground wire.
[0035] A first limiting groove 114 is provided on both sides of the inner wall of the clamping support 11, and a first limiting block 25 is integrally formed at the end of the L-shaped conductive clamping member 21, and the first limiting block 25 is slidably connected in the first limiting groove 114. A second limiting block 117 is integrally formed at the lower end of the clamping support 11, and a second limiting groove 24 is provided in the middle of the bottom end of the L-shaped conductive clamping member 21, and the second limiting block 117 is slidably connected in the second limiting groove 24, ensuring that the L-shaped conductive clamping member 21 can slide vertically up and down relative to the clamping support 11, further ensuring the reliability of the clamping stroke.
[0036] The driving holding member 3 is electrically insulated from the clamping seat 1 and the clip 2. The driving holding member 3 includes a holding tube 31 and a driving screw 34. The holding tube 31 is fixed to the bottom of the clamping support 11; the driving screw 34 is threaded through the clamping support 11, and the driving screw 34 is rotatably connected to the clip 2. The bottom end of the holding tube 31 is rotatably connected to the anti-slip handle 33, and a long tube 32 is fixedly connected between the driving screw 34 and the anti-slip handle 33. A threaded seat 112 is fixedly provided at the bottom of the clamping support 11, and the driving screw 34 is threadedly connected to the threaded seat 112. The bottom end of the L-shaped conductive clamping member 21 is fixedly connected to the assembly part 23, and the top end of the driving screw 34 is rotatably connected to the assembly part 23.
[0037] When in use, first flip the rotating clamp 12 to the position where the first limit piece 125 and the second limit piece 116 are engaged with each other, then, the clamping top plate 121 enters from one side of the power connection part, and the power connection part contacts the driving end 122 and pushes the rotating clamp 12 to rotate until the driving end 122 is placed in the air avoidance groove 113. At this time, the power connection part is located in the clamping gap between the clamping top plate 121 and the L-shaped conductive clamping part 21. Then, hold the bottom end of the holding tube 31 with one hand and rotate the anti-slip handle 33 with the other hand, so that the anti-slip handle 33 drives the driving screw 34 to rotate through the long tube 32, so that the L-shaped conductive clamping part 21 slides inside the clamping support 11 to narrow the clamping gap, thereby achieving clamping of the connecting part. Since the connecting part 22 is grounded, the power connection part is also grounded.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
