Referring to fig. 1, fig. 1 is a schematic structural diagram of a suspension clamp 100. A suspension clamp 100 includes a connecting rod 110, a fixing bracket 130, a suspension clamp 150, and a shoe 170. The cross-section of the connecting rod 110 is polygonal. The fixing bracket 130 and the suspension clamp 150 are provided with fixing holes 131 with the same shape as the cross section of the connecting rod, the fixing holes 131 are matched with the connecting rod 110 to realize the relative rest of the positions of the fixing bracket 130 and the suspension clamp 150, the connecting rod 110 penetrates through the fixing holes 131, and the suspension clamp 150 is movably connected with the bottom support 170. The suspension clamp 150 further comprises a fixing bolt 151, the suspension clamp 150 is further provided with a fixing channel 153, the bottom support 170 is provided with a limiting hole 171, the fixing bolt 151 penetrates through the fixing channel 153 and the limiting hole 171, the suspension clamp 150 is connected with the bottom support 170 through the fixing bolt 151, one end, close to the limiting hole 171, of the fixing bolt 151 is provided with threads (not shown in the figure) in a surrounding mode and used for installing a nut 155, and the fixing bolt 151 and the nut 155 jointly achieve the purpose that the bottom support 170 is fixed on the suspension clamp 150. When the suspension clamp 100 is installed, a worker needs to fix the fixing bracket 130 to a telegraph pole or a tower pole by screws or welding (the fixing end of the fixing bracket 130 fixed to the telegraph pole or the tower pole has various specifications, and the specific shape can be customized according to the shape of the place where the fixing bracket is actually installed); the nuts 155 on one end of the fixing bolts 151 are then rotated to remove the designated positions of the power lines from the upper side of the shoe 170, the fixing bolts 151 are passed through the retaining holes 171 of the shoe 170, and the nuts 155 are then installed on the fixing bolts 151, and the power lines are clamped by the suspension clamps 150 and the shoe 170 so that the positions of the power lines on the shoe 170 are kept stationary. Finally, the fixing holes 131 of the fixing bracket 130 and the suspension clamp 150 are kept consistent with the cross-sectional shape of the connecting rod 110, the connecting rod 170 is ensured to be inserted into the fixing holes 131, and the connecting rod 110 is fixed on both sides of the fixing bracket 130 by using lock nuts or welding, so that the fixing bracket 130 and the suspension clamp 150 are kept still. It should be noted that, in order to facilitate the assembly and installation of the connecting rod 170, the fixing bracket 130 and the suspension clamp 150 by the worker, the cross-sectional shape of the connecting rod 170 and the shape of the fixing hole 131 are regular polygons in this embodiment, and in other embodiments, may be other shapes, and it is sufficient if the positions of the fixing bracket 130 and the suspension clamp 150 can be kept relatively still.

Referring to fig. 2 and 3, fig. 2 is a schematic structural view of a connecting rod, and fig. 3 is a schematic sectional view of a combination of the connecting rod and a fixing hole. The cross-section of both ends of the connecting rod 170 is circular, and both ends of the connecting rod 170 are provided with a screw (not shown) and a nut (not shown). In order to make the connection between the fixing bracket 130 and the suspension clamp 150 more stable, both ends of the connecting rod 170 are provided with threads for installing nuts, the middle portion of the connecting rod is polygonal (the length of the polygonal is equal to the thickness of the end of the fixing bracket 130 provided with the fixing hole 131), the polygonal portion of the connecting rod 170 is used for limiting the rotation of the fixing bracket 130 and the suspension clamp 150 around the connecting rod 170, and the nuts are used for limiting the movement of the fixing bracket 130 and the suspension clamp 150 along the length direction of the connecting rod 170.

To make the effect of the pair of suspension clamps 100 more pronounced, the side of the suspension clamp 150 remote from the shoe 170 is provided with a flat 157, the flat 157 being used to place a weight. When the suspension clamp 100 is used in a windy or windy place, the surface of the connecting rod 110 is easily worn due to the wind force when the connecting rod 110 is used for a long time, the connecting rod 110 may not be enough to limit the displacement of the fixing bracket 130 and the suspension clamp 150, and at this time, the worker may selectively install some weights on the suspension clamp 100 to increase the weight of the suspension clamp 100. When the worker installs the weight block, the end of the suspension clamp 150 connected to the fixing bracket 130 needs to penetrate through the weight block, so that the weight block falls on the plane 157. Compare with traditional suspension clamp, install the balancing weight at suspension clamp 150's upside, can avoid the balancing weight to break away from with suspension clamp in long-term use, the balancing weight has reduced the potential safety hazard from the condition that drops in the air.

Referring to fig. 4, fig. 4 is a sectional view of the suspension clamp and the bottom frame. The one side that the suspension clamp 150 is close to the collet 170 is the wave, and the shape that the shape of one side that the collet 170 is close to the suspension clamp 150 is laminated with the shape that the suspension clamp 150 is close to one side of collet 170, can increase the area of contact of suspension clamp 150 and collet 170 and power transmission line, increases the frictional force of suspension clamp 150 and collet 170 and power transmission line. The side of the suspension clamp 150 adjacent to the shoe 170 and the side of the shoe 170 adjacent to the suspension clamp 150 are provided with anti-slip threads (not shown) to provide a more secure grip of the suspension clamp 100 on the transmission line.

Further, both ends of one side of the shoe 170 near the suspension clamp 150 are inclined downward. In the use, receive the effect of wind force, the power transmission line can produce the friction with the both ends of collet 170, and the both ends downward sloping of collet 170 can reduce the friction between power transmission line and the collet 170, reduces the wearing and tearing of power transmission line, the life of extension power transmission line. The suspension clamp 150 is solid. The weight of the suspension clamp 100 is increased, so that the suspension clamp 100 has longer service life and better effect.
