[0030] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.
[0031] The utility model provides a grounding wire conductor end clamp. The driving rod drives the swing rod to flip through the connecting rod to realize the opening and closing of the clamping mechanism to clamp the grounding wire. The driving rod, the swing rod and the connecting rod of the flip rod assembly can form a self-locking structure when closed to prevent the clamp from loosening due to the shaking of the grounding wire. Please refer to Figure 1-Figure 5 , including: a supporting mechanism 100, a turning rod assembly 200 and a pressing mechanism 300.
[0032] The support mechanism 100 includes a support plate 110, a mounting panel 120, a support block 130, a support V-groove 140, an upper hinge shaft 150 and a lower hinge shaft 160. The mounting panel 120 is arranged on the left side of the support plate 110, the support block 130 is arranged on the right side of the support plate 110, the support V-groove 140 is arranged on the top of the support block 130, the upper hinge shaft 150 is arranged on the left side of the top of the support plate 110, and the lower hinge shaft 160 is arranged on the lower right side of the upper hinge shaft 150;
[0033] Among them, the installation panel 120 is provided with evenly distributed through holes for connecting bolts to install and position the support mechanism 100. The top of the support plate 110 is a triangle with the left side higher and the right side lower, and the end of the grounding wire is placed in the support V-groove 140.
[0034] The flip rod assembly 200 is connected to the support plate 110, and includes a swing rod 210, a driving rod 220, a connecting rod 230 and a connecting block 240. The left end of the swing rod 210 is rotatably connected to the upper hinge shaft 150, and the lower end of the driving rod 220 is rotatably connected to the lower hinge shaft 160. The connecting rod 230 is hinged between the swing rod 210 and the driving rod 220, and a connecting block 240 is arranged at the right end of the swing rod 210.
[0035] The connection positions of the swing rod 210, the driving rod 220, and the connecting rod 230 are as follows: Figure 1 and Figure 3 As shown, the upper end of the connecting rod 230 is rotatably connected to the driving rod 220, and the lower end of the connecting rod 230 is rotatably connected to the swing rod 210. The staff holds the driving rod 220 and rotates the driving rod 220 to the left, so that the driving rod 220 rotates on the lower hinge shaft 160. When the driving rod 220 rotates, the swing rod 210 is pulled by the connecting rod 230, so that the swing rod 210 rotates on the upper hinge shaft 150, thereby driving the connecting block 240 to move.
[0036] Figure 1 and Figure 3In the closed state, the connecting rod 230 is vertically supported between the rocker arm 210 and the driving rod 220. The driving rod 220 can provide a lateral force to drive the vertical connecting rod 230 to move, thereby driving the rocker arm 210 to move. However, the rocker arm 210 will be resisted by the vertical connecting rod 230, so that the rocker arm 210 cannot drive the connecting rod 230 to move, forming a self-locking structure of one-way transmission.
[0037] The clamping mechanism 300 is disposed on the connecting block 240 , and the clamping mechanism 300 moves along with the swing rod 210 , so that a clamp is formed between the clamping mechanism 300 and the supporting block 130 to clamp and fix the ground wire end.
[0038] Since the swing rod 210 has a limited range of motion, it cannot continue to clamp after closing, so that the clamp formed between the clamping mechanism 300 and the support block 130 can only clamp the grounding wire of a fixed thickness. For this reason, a screw hole 250 is provided at the center of the connecting block 240, and sliding holes 260 are provided on both sides of the screw hole 250. The clamping mechanism 300 includes a pressing block 310, a downward pressing V-groove 320, a screw rod 330 and a sliding rod 340. The pressing block 310 has a downward pressing V-groove 320 at the bottom, a screw rod 330 connected to the screw hole 250 is provided at the top of the pressing block 310, and sliding rods 340 connected to the sliding holes 260 are provided on both sides of the top of the pressing block 310.
[0039] By rotating the screw rod 330, the pressing block 310 moves up and down, changing the pressing height of the pressing block 310, thereby changing the distance between the pressing block 310 and the supporting block 130, so that grounding wires of different diameters can be clamped. When the pressing block 310 moves up and down, the sliding rod 340 slides in the sliding hole 260 to provide guidance and anti-rotation limit.
[0040] Since the screw rod 330 and the pressure block 310 need to rotate relative to each other, otherwise the pressure block 310 will rotate with the screw rod 330, and it is impossible to ensure that the supporting V-groove 140 and the pressing V-groove 320 are relative to each other. For this reason, a bearing 350 is arranged between the pressure block 310 and the screw rod 330, so that the pressure block 310 can rotate freely at the lower end of the screw rod 330.
[0041] If the bottom of the pressing block 310 contacts the top of the supporting block 130, it will not be able to continue clamping. For this reason, a movable groove 170 is opened on the inner side of the supporting V-groove 140, and the outer part of the pressing block 310 is embedded in the inner part of the movable groove 170, so that the pressing block 310 can be pressed down and embedded in the movable groove 170, thereby expanding the movable space and improving the clamping effect.
[0042] Due to the existence of the movable groove 170, when clamping, when the inner wall of the movable groove 170 and the outer wall of the pressing block 310 slide relative to each other, a shear structure will be formed, which is easy to damage the grounding wire. For this reason, a movable part 400 is arranged inside the movable groove 170, and the movable part 400 includes a clamping block 410, a landslide 420 and an extrusion inclined surface 430. The clamping block 410 is arranged on the left and right sides of the movable groove 170, and a landslide 420 that fits the downward pressing V-groove 320 is arranged on one side of the top of the clamping block 410, and an extrusion inclined surface 430 perpendicular to the landslide 420 is arranged on the other side of the top of the clamping block 410;
[0043] When the pressing block 310 moves downward, the inclined surface of the V-groove 320 is pressed downward to squeeze the slide 420, so that the clamping blocks 410 are close to each other, and the clamping blocks 410 contact the grounding wire through the extrusion inclined surface 430. The front and rear end surfaces of the clamping block 410 are flush with the front and rear end surfaces of the pressing block 310, so that the contact surface provides a uniform clamping force on the grounding wire.
[0044] Since the clamping block 410 will move closer under the pressure of the downward pressing V-groove 320, but after the downward pressing V-groove 320 moves upward, the clamping block 410 cannot be reset. For this reason, a reset spring 440 is connected between the clamping blocks 410. After the downward pressing V-groove 320 moves upward, the external force acting on the clamping block 410 disappears, and the clamping block 410 is reset to the left and right ends of the movable groove 170 under the action of the reset spring 440.
[0045] Since manual operation is required, in order to facilitate operation, a non-slip handle is provided on the top of the driving rod 220, and a non-slip rotary handle is provided on the top of the screw rod 330, so as to facilitate hand grasping for operation.
[0046] In specific use, the bolts are fixed in the working position by the mounting panel 120 support mechanism 100, and the hand pulls the driving rod 220, and the driving rod 220 rotates on the lower hinge shaft 160. While the driving rod 220 rotates, the connecting rod 230 pulls the swing rod 210, so that the swing rod 210 rotates on the upper hinge shaft 150, thereby driving the connecting block 240 to move, open the clamping mechanism 300, put the grounding wire end into the supporting V-groove 140, and pull the driving rod 220 in the opposite direction to close the clamping mechanism 300. After closing, the swing rod 210 The rod 210 cannot drive the connecting rod 230 to move, forming a self-locking structure of one-way transmission. By rotating the screw rod 330, the pressing block 310 moves up and down, and the pressing height of the pressing block 310 is changed. When the pressing block 310 moves downward, the inclined surface of the downward pressing V-groove 320 squeezes the slide 420, so that the clamping blocks 410 are close to each other, and the extruded inclined surface 430 of the clamping block 410 contacts the grounding wire, so that the downward pressing V-groove 320 and the clamping block 410 are clamped on the end of the grounding wire, and the grounding wire is fixedly clamped, which is suitable for clamping grounding wires of different diameters.
[0047] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
