Implementation
[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] See also Figure 1 , Figure 2 and Figure 3The utility model provides a technical solution: a self-locking grounding wire conductor clamp, comprising a clamp body 1, a grounding wire 2 is connected to the left end of the bottom of the clamp body 1, a through hole 3 is provided at the bottom of the clamp body 1, a clamping groove 4 is provided at the top of the inner top of the through hole 3, a rectangular groove 5 is provided at the right side wall of the inner side of the through hole 3, a rotating rod 6 is hinged in the rectangular groove 5, an arc clamping plate 7 is integrally formed at the left end of the rotating rod 6, a sliding hole 8 is provided on the top wall of the rectangular groove 5, a first driving rod 9 is slidably installed on the inner side wall of the sliding hole 8, and a first contact plate 10 is integrally formed at the top of the first driving rod 9;
[0019] An installation cavity 11 is provided on the upper inner side of the clamp body 1, a rocker arm 12 is hingedly connected to the interior of the installation cavity 11, a through hole 13 is provided on the left side of the bottom wall of the installation cavity 11, a second driving rod 14 is slidably installed on the inner side wall of the through hole 13, a second contact plate 15 is integrally formed on the top of the second driving rod 14, the left and right ends of the rocker arm 12 are respectively attached to the top of the second contact plate 15 and the first contact plate 10, and the bottom end of the first driving rod 9 is attached to the top of the rotating rod 6.
[0020] like Figure 1 As shown, the bottom end of the through hole 13 is connected to the clamping groove 4, and the top of the side wall of the bare wire is pressed against the bottom end of the second driving rod 14. Through the linkage effect of the rocker arm 12, the right end of the rocker arm 12 exerts downward pressure on the first driving rod 9, thereby causing the rotating rod 6 to flip, and then causing the arc-shaped clamping plate 7 to swing downward and clamp on the lower side of the bare wire.
[0021] Specifically, the arc surface of the top wall of the clamping groove 4 matches the arc surface of the bare wire to be clamped.
[0022] Specifically, spherical surfaces 16 are provided at both left and right ends of the swing rod 12 , and the bottom ends of the two spherical surfaces 16 are respectively attached to the top of the second contact plate 15 and the top of the first contact plate 10 .
[0023] The provision of the spherical surface 16 can reduce the contact area between the two ends of the swing rod 12 and the second contact plate 15 and the top of the first contact plate 10, thereby increasing the smoothness of the contact sliding.
[0024] Specifically, a convex surface 17 is provided at the bottom end of the first driving rod 9 , and the convex surface 17 is attached to the top of the rotating rod 6 .
[0025] The convex surface 17 has a similar effect to the spherical surface 16 described above.
[0026] Specifically, the clamp body 1 includes a main body 18 , a top plate 20 and a bolt 22 . The main body 18 has four top corners with threaded grooves 19 , the top plate 20 has four mounting holes 21 , and the bottom end of the bolt 22 passes through the mounting hole 21 and is screwed into the threaded groove 19 .
[0027] like Figure 2As shown, by dividing the clamp body 1 into a main body 18 and a top plate 20, the mounting cavity 11 is now completely located at the top position of the frame body 1. Through this arrangement, it is convenient to install the rocker arm 12 in the mounting cavity 11, and it is also convenient to install the first drive rod 9 and the second drive rod 14.
[0028] Specifically, the mounting hole 21 is a T-shaped hole.
[0029] By setting the mounting hole 21 as a T-shaped hole, the bolt 22 can be completely located in the mounting hole 21, thereby increasing the flatness of the top of the clamp body 1.
[0030] Specifically, the exterior of the body 18 and the top plate 20 are both bonded with an insulating layer 23 .
[0031] Working principle: Figure 1 As shown, through the gravity of the clamp body 1 (the clamp body 1 can be a conductive metal with a large gravity), the clamp body 1 is sleeved on the bare wire, and the bare wire exerts an upward pressure on the second drive rod 14. Through the linkage effect of the swing rod 12, the right end of the swing rod 12 exerts a downward pressure on the first drive rod 9, thereby causing the rotating rod 6 to flip over, and then causing the arc-shaped clamping plate 7 to swing downward and clamp the lower side of the bare wire.
