Description

Technical Field

[0001] The present invention relates to the field of electrical safety tools, and in particular to a grounding wire conductive end structure and a use method thereof. Background Art

[0002] The grounding wire is a widely used electrical safety tool. It can be divided into busbar type and line type according to the use environment. The busbar type grounding wire adopts a flat spiral structure. In actual application, it is difficult to fix and rotate the conductive end and it is easy to fall off. During the rotation of the operating rod, due to the loose fit between the conductive end and the busbar, the entire conductive end will shake at the same time as the rod rotates, and it is difficult for the push-down plate to form relative movement and move forward, resulting in difficulty in hanging; the conductive end shakes left and right. If used improperly, it will cause the conductive end to fall off. When it touches the electrical equipment around the busbar, it will cause a great safety risk.

[0003] At the same time, since the busbar grounding wire and the line grounding wire are not interchangeable, it also brings inconvenience to actual use. Summary of the invention

[0004] The technical problem to be solved and the technical task proposed by the present invention are to improve and perfect the existing technical solutions, and provide a grounding wire conductive end structure and a method of using the same, so as to stably, reliably and labor-savingly realize the hanging of the grounding wire conductive end. To this end, the present invention adopts the following technical solutions.

[0005] A grounding wire conductive end structure, comprising a conductive end body, a top plate, an upper push plate, a lower push plate, two guide rods and an intermediate rod located between the two guide rods; the conductive end body is in a "[" shape, comprising two upper and lower parallel horizontal plates and a vertical plate connecting the two horizontal plates; the guide rod passes through the horizontal plate on the upper part of the conductive end body, the lower end of the guide rod is connected to the upper push plate after passing through an elastic member, the upper end of the guide rod is connected to the top plate, the intermediate rod is connected to the upper horizontal plate of the conductive end body, and can be erected and turned over; a vertical threaded hole is provided in the middle of the lower horizontal plate, and the upper part of the operating rod is threadedly connected to the threaded hole of the lower horizontal plate; the operating rod passes through the threaded hole of the conductive end body and is connected to the lower push plate; the vertical plate is provided with a guide rail matching the upper push plate and the lower push plate;

[0006] The lower plane of the upper push plate and the upper plane of the lower push plate are provided with arc grooves corresponding to the positions, and the diameter of the arc grooves is larger than the diameter of the matching circular wire. It can conveniently provide the clamping position of the wire, so that the clamping of the wire is more stable and reliable. When in use, first stand up the middle rod to support the top plate, so that the spring is in the initial compression state, then align the gap between the upper push plate and the lower push plate with the busbar, and then pull the operating rod by hand to make the middle rod break away from the contact with the top plate and overturn. At this time, the upper push plate pops up downward, and under the action of the spring force, the upper push plate and the lower push plate cooperate to clamp the busbar, which plays an initial fixing role; then rotate the operating rod to move the lower push plate up until it is completely clamped. Due to the action of the elastic member, the upper push plate and the lower push plate always clamp the busbar, and the conductive end of the grounding wire is stably, reliably and labor-savingly connected. The guide rail allows the upper push plate and the lower push plate to move only up and down, limiting the rotation of the upper push plate and the lower push plate.

[0007] As a further improvement and supplement to the above technical solution, the present invention also includes the following additional technical features.

[0008] The elastic member is a spring, and the upper plane of the upper push plate is provided with a spring groove. The spring has low cost and good elastic stability. The spring groove provides a compression space for the spring. After the mounting is completed, the spring is completely located in the spring groove, and the lower push plate is in close contact with the upper horizontal plate to ensure that the contact resistance requirements are met. The upper and lower ends of the guide rod are respectively welded to the top plate and the upper push plate. The welding method makes the connection more secure.

[0009] The middle rod comprises a straight rod and a ring at the lower end of the straight rod, the ring passes through the through hole of the horizontal plate in the front and back directions and there is a gap between the ring and the through hole, so that the middle rod can be turned over in the front and back directions. The structure is simple and can be easily erected by hand and turned over naturally.

[0010] Another object of the present invention is to provide a method for using the conductive end structure of a grounding wire, which comprises the following steps:

[0011] 1) First, raise the middle rod to support the top plate, so that the spring is in the initial compression state;

[0012] 2) Then align the gap between the upper push plate and the lower push plate with the busbar, or align the arc-shaped grooves of the upper push plate and the lower push plate with the wire and insert them;

[0013] 3) Pull the operating lever by hand to make the middle lever break away from the contact with the top plate and overturn. At this time, the upper push plate pops down and cooperates with the lower push plate to clamp the busbar or round conductor. When clamping the round conductor, put the conductor into the arc groove;

[0014] 4) Then rotate the operating lever to move the lower push plate up until it is fully clamped. Under the action of the spring, the upper push plate and the lower push plate always clamp the busbar or round conductor to achieve the connection of the conductive end of the grounding wire.

[0015] 5) When disassembly is required, rotate the operating lever in the opposite direction and move the push plate downward to separate the conductive end of the grounding wire from the busbar or round conductor.

[0016] Beneficial effects: Through the action of the spring, the conductive end of the grounding wire is stably, reliably and labor-savingly connected to the busbar and the round conductor, avoiding the phenomenon of falling off due to insufficient initial clamping force during the traditional grounding wire end connection process, and preventing the occurrence of safety accidents. Through the groove structure, the grounding wire can be used on the busbar and the line. BRIEF DESCRIPTION OF THE DRAWINGS
