[0003] Existing grounding clamps hold grounding wires through clamping jaws; however, the size of the jaws can be adjusted within a large range and the degree of freedom of adjustment is low, resulting in a jaw shape that is too monotonous. Since grounding wires have different clamping positions, if the jaws are limited in terms of diameter and shape, they may not be able to meet the needs of complex grounding wires, thus reducing the clamping flexibility of the grounding clamps and failing to meet the needs of grounding wires on a large scale.

[0044] like Figure 1-4 A grounding clamp includes: a base 1 and a fixing clamp 2;
[0045] The fixing clamp 2 is installed on the base 1;
[0046] The fixing clamp 2 includes: a fixing clamp 20, a first shaft 21, a second shaft 22, a third shaft 23, a movable arm 25, a movable clamp 26, and a transmission plate 27;
[0047] The fixed clamp 20 is mounted on the base 1; the first shaft 21, the second shaft 22, and the third shaft 23 are distributed in parallel; the first shaft 21 is mounted on the fixed clamp 20, one end of the movable arm 25 is rotatably and adjustablely limited to the first shaft 21, and the movable arm 25 rotates around the first shaft 21; the other end of the movable arm 25 is mounted on the second shaft 22; one end of the transmission plate 27 is rotatably and adjustablely limited to the movable arm 25, and the other end of the transmission plate 27 is connected to the third shaft 23; one end of the movable clamp 26 is rotatably connected to the second shaft 22, and the other end of the movable clamp 26 is rotatably connected to the third shaft 23;
[0048] The fixed clamp 20 is provided with an L-shaped groove 201, and the movable clamp 26 is movable in the L-shaped groove 201. The L-shaped groove 201 and the movable clamp 26 form a clamping opening 200 with clamping function.
[0049] This solution provides a grounding wire clamp, which has a first axis 21, a second axis 22 and a third axis 23 arranged in parallel on the fixed clamp 2. The movable arm 25 can drive the movable clamp 26 to rotate around the first axis 21 with a large range. The movable clamp 26 can also rotate around the second axis 22 and the third axis 23 with a small range. The large range of motion of the movable clamp 26 effectively improves the clamping flexibility of the clamp 200, can fully clamp the grounding wire, and avoid the problem of unstable clamping leading to disengagement.
[0050] Specifically, the fixed clamp 20 is installed on the base 1, the first shaft 21 is set on the fixed clamp 20, the second shaft 22 is set on the movable arm 25, and the third shaft 23 is set on the transmission plate 27; the end of the movable arm 25 away from the second shaft 22 is rotatably and adjustablely limited to the first shaft 21. The rotatable and adjustable limiting method here means that the movable arm 25 can be limited to the first shaft 21 in a known way before and after rotating around the first shaft 21, thereby ensuring that the angle of the movable arm 25 before and after rotation is fixed. For example, it can be fixed by clamps, screws, etc., as long as the angle of the movable arm 25 before and after rotation is fixed. The movable clamp 26 is rotatably connected to the second shaft 22 and the third shaft 23 at two positions. One end of the movable clamp 26 can rotate around the second shaft 22 and also around the third shaft 23. The transmission plate 27 is rotatably and adjustablely limited at the end away from the third shaft 23 (the same rotatable and adjustable limiting method as described above) to the movable arm 25. After one end of the transmission plate 27 is rotated, it is limited to the movable arm 25. Thus, this solution can release the limitation of the transmission plate 27 on the movable arm 25, adjust the angle of the movable clamp 26, and cause the angle of the transmission plate 27 on the third shaft 23 to change, based on the fact that the movable clamp 26 is rotatably connected to the second shaft 22 and the third shaft 23 respectively. The angle that the movable clamp 26 needs to adjust can be adaptively adjusted under the action of the second shaft 22 and the third shaft 23, thereby adjusting the clamping opening 200 formed between the movable clamp 26 and the L-shaped groove 201 to the required shape and size. More specifically, because the movable arm 25 has a larger range of motion, it indirectly drives the movable clamp 26 to rotate around the first shaft 21, which can greatly adjust the range of motion of the movable clamp 26 and can be used for coarse adjustment of the size of the clamping opening 200. Since the two ends of the movable clamp 26 are connected to the second shaft 22 and the third shaft 23 respectively, and the range of motion of the transmission plate 27 is smaller, the transmission plate 27 can be used for fine adjustment of the movable clamp 26. In this way, the clamping opening 200 of this solution has high clamping flexibility, and the size and shape of the clamping opening 200 can be adjusted as needed to fully clamp grounding wires of different shapes and avoid the problem of unstable clamping leading to disengagement.
[0051] Optimally, it also includes: a first limiting pin 3;
[0052] The fixing clamp 2 also includes: a fourth shaft 24;
[0053] The fourth shaft 24 is mounted on the base 1, and the fourth shaft 24 is parallel to the first shaft 21;
[0054] The fixing clamp 20 is rotatably mounted on the fourth shaft 24, and the fixing clamp 20 rotates around the fourth shaft 24; the first limiting pin 3 is movably and adjustably limited to the base 1, and one end of the first limiting pin 3 abuts against the fixing clamp 20 to restrict the rotation of the fixing clamp 20.
[0055] The fixed clamp 20 of this solution, as the main component of the clamp 200, is rotatable on the base 1. Specifically, the fourth shaft 24 is mounted on the base 1, and the fixed clamp 20 can rotate around the fourth shaft 24. Combined with the movable clamp 26, which can rotate around the first shaft 21 of the fixed clamp 20, the rotatable feature of the fixed clamp 20 allows the direction of the clamp 200 of the fixed clamp 2 to be adjusted. The clamp 200 can rotate around the fourth shaft 24 to adjust its orientation, improving the clamping flexibility of the clamp 200. The first limiting pin 3 can move on the base 1 and abut against the fixed clamp 20, limiting the angle of the fixed clamp 20 after adjustment. The first limiting pin 3 is movably and adjustably limited on the base 1 in a known manner; for example, in one embodiment, such as... Figure 4 The first limiting pin 3 is threadedly fitted to the base 1. Adjusting the thread fit between the first limiting pin 3 and the base 1 can cause the first limiting pin 3 to abut against the fixed clamp 20, thereby limiting the fixed clamp 20. For example, in one embodiment, the first limiting pin 3 passes through the hole structure of both the base 1 and the fixed clamp 20 in sequence, which can fix the angle of the fixed clamp 20 after rotation.
[0056] Optimally, it also includes: arm limiting component 6;
[0057] The base 1 is provided with a fixed seat 11 and an arm limiting seat 12, and the fixing clamp 20 is installed on the fixed seat 11;
[0058] The arm limiting member 6 is movably and adjustablely limited to the arm limiting seat 12, and one end of the arm limiting member 6 is located on the fixed seat 11; the movable arm 25 rotates around the first axis 21 and abuts against the arm limiting member 6, and the arm limiting member 6 is used to restrict the opening of the clamp 200.
[0059] The arm limiting member 6 can move to the arm limiting seat 12. After the arm limiting member 6 moves, it is limited to the arm limiting seat 12. The position of the arm limiting member 6 is limited to the arm limiting seat 12. Therefore, when the movable arm 25 abuts against the arm limiting member 6, the swing angle of the arm limiting member 6 is fixed. The arm limiting member 6 cannot continue to rotate around the first axis 21 in the direction of opening of the clamp 200, thereby limiting the opening of the clamp 200 and preventing the clamp 200 from disengaging from the grounding wire.
[0060] Alternatively, the arm limiting seat 12 may be provided with an internal thread structure, and the arm limiting member 6 may be provided with an external thread structure.
[0061] The arm limiting member 6 is threadedly engaged with the arm limiting seat 12; the arm limiting member 6 rotates relative to the arm limiting seat 12, so that the arm limiting member 6 moves within the arm limiting seat 12.
[0062] The arm limiting member 6 has an external thread structure, and the arm limiting seat 12 has an internal thread structure. The external thread structure of the arm limiting member 6 is threaded into the internal thread structure of the arm limiting seat 12. When the arm limiting member 6 is rotated and adjusted, the arm limiting member 6 rotates relative to the internal thread structure of the arm limiting seat 12. The arm limiting member 6 can move towards or away from the fixed clamp 20, thereby moving the arm limiting member 6 to the arm limiting seat 12.
[0063] Alternatively, the movable arm 25 may be provided with toothed patterns 251 at the contact position with the arm limiting member 6.
[0064] The toothed texture 251 replaces the local smooth surface of the movable arm 25, which can improve the local roughness of the movable arm 25; when the arm limiting member 6 abuts against the toothed texture 251, the friction between the two increases, thereby improving the limiting effect of the arm limiting member 6 on the movable arm 25.
[0065] Optimally, it also includes: a second limiting pin 4;
[0066] The transmission plate 27 has a transmission hole 271 at one end away from the third shaft 23; the second limiting pin 4 has a torsion head 41 and a limiting screw 42, the torsion head 41 is installed at both ends of the limiting screw 42, and at least one of the torsion heads 41 is threaded to the limiting screw 42.
[0067] The limiting screw 42 passes through the transmission hole 271 and through the movable arm 25. The torsion heads 41 are located on both sides of the movable arm 25. The two torsion heads 41 rotate and come into contact with each other, pressing the transmission plate 27 against the movable arm 25.
[0068] The second limiting pin 4 of this scheme can limit the transmission plate 27 to the movable arm 25. The second limiting pin 4 is provided with a limiting screw 42 and a torsion head 41. The limiting screw 42 has an external thread structure, and at least one torsion head 41 has an internal thread structure (it is possible that only one torsion head 41 is fixed to the limiting screw 42). The torsion head 41 is threadedly engaged with one end of the limiting screw 42. The limiting screw 42 passes through the transmission hole 271 of the transmission plate 27 and both sides of the movable arm 25, so that the torsion head 41 is located on both sides of the movable arm 25. At this time, it is only necessary to rotate the torsion head 41 with the internal thread structure to make the relative positions of the two torsion heads 41 closer or farther away. When they are close, the transmission plate 27 is pressed against the movable arm 25, and when they are far apart, the transmission plate 27 and the movable arm 25 are released, thereby limiting the transmission plate 27 to the movable arm 25.
[0069] Alternatively, the fixing clamp 2 may further include: a torsion spring 28;
[0070] The torsion spring 28 is sleeved on the second shaft 22. One elastic end of the torsion spring 28 is connected to the movable arm 25, and the other elastic end of the torsion spring 28 is connected to the movable clamp 26, so that the movable clamp 26 can move elastically.
[0071] In this design, the torsion spring 28 is mounted on the second shaft 22. The two elastic ends of the torsion spring 28 can twist relative to each other. When the movable clamp 26 rotates around the second shaft 22, the movable clamp 26 can compress the elastic ends of the torsion spring 28. On the one hand, the torsion spring 28 can provide a buffering effect for the movable clamp 26, and the clamp 200 has elastic movement capability at the movable clamp 26, thereby clamping the grounding wire in a complex position. On the other hand, when passing through the concave and convex positions of the grounding wire, the elastic movement of the movable clamp 26 can be adaptively adjusted to pass through obstacles. Furthermore, in the embodiment where the second limiting pin 4 presses the transmission plate 27 against the movable arm 25, when the torsion head 41 can press the transmission plate 27, the movable clamp 26 can still move elastically to a small extent in a non-absolute pressing state, thereby adaptively adjusting the angle when passing through concave and convex positions and improving the clamping flexibility of the clamp 200.
[0072] Alternatively, the movable clamp 26 may have a plurality of protrusions 261 on one side of the clamping opening 200.
[0073] The protrusion 261 protrudes from the surface of the movable clamp 26, which can increase the local roughness of the clamp 200, thereby increasing the friction of the clamp 200 when clamping the grounding wire and improving the clamping stability.
[0074] Optimally, it also includes: a flexible adjustment component 5;
[0075] The fixing clamp 20 is provided with a U-shaped groove 202 on the side of the L-shaped groove 201, and a part of the movable arm 25 is located in the U-shaped groove 202;
[0076] The elastic adjustment component 5 includes: a fixing post 51 and a clamping spring 52;
[0077] The fixing post 51 is installed in the U-shaped groove 202, one end of the clamping spring 52 is limited to the fixing post 51, and the other end of the clamping spring 52 is connected to the movable arm 25, so that the clamp 200 remains elastically open.
[0078] The elastic adjustment component 5 of this solution can keep the clamp 200 in an open state. Specifically, the U-shaped groove 202 is adjacent to the L-shaped groove 201, and the movable arm 25 passes through the U-shaped groove 202. The fixed post 51 is fixed to the U-shaped groove 202 and is used to connect one elastic end of the clamping spring 52. The other elastic end of the clamping spring 52 is connected to the movable arm 25. When the clamping spring 52 is in a contracted state, it generates a pushing force on the movable arm 25 and the fixed post 51, so the clamp 200 can remain in an elastically open state. When adjusting the size of the clamp 200, the movable arm 25 will not fall, which facilitates accurate adjustment of the size of the clamp 200. At the same time, when adjusting the relative position of the movable clamp 26 in the L-shaped groove 201, the movable clamp 26 can compress the clamping spring 52 through the movable arm 25, thus achieving the effect of elastically adjusting the clamp 200.
[0079] Optimally, one of the openings of the U-shaped groove 202 faces downward toward the base 1, and an adjustment gap 203 is formed between the opening of the U-shaped groove 202 and the base 1; the first shaft 21 is installed in the U-shaped groove 202, and the movable arm 25 moves through the opening of the U-shaped groove 202 and the adjustment gap 203.
[0080] In this design, an adjustment gap 203 is reserved between the base 1 and the slot of the U-shaped groove 202. The movable arm 25 moves through the slot of the U-shaped groove 202 and the adjustment gap 203. The adjustment gap 203 can increase the range of motion of the movable arm 25, thereby increasing the swing angle of the movable clamp 26 and making the upper limit of the diameter of the clamp 200 larger.
[0081] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
