Detailed Description

The technical scheme of the utility model is further explained by specific embodiments in the following with the accompanying drawings:

example 1

As shown in fig. 1-4, a terminal of a grounding wire, which is convenient to disassemble and easy and fast to operate, is provided in the grounding process of power construction.

The grounding unit comprises a screw rod 1, a base 2, a main rod 3, a guide rod 4, a limiting disc 5 and a transition plug disc 6. As shown in fig. 1 and 2, the screw bar 1 is fixedly mounted on the lower surface of the base 2. The effect of hob 1 is used for being fixed in the underground, and helical structure screw in is underground convenient, and is more stable behind the screw in. A main rod 3 is fixedly arranged on the base 2, and a guide rod 4 is fixedly arranged on the main rod 3. The top end of the guide rod 4 is fixedly provided with a limiting disc 5.

The guide rod 4 is used for installing a transition plug disc 6, and the transition plug disc 6 can move up and down along the guide rod 4. Meanwhile, the upper surface and the lower surface of the transition plug disc 6 are of inclined structures, so that the transition plug disc is convenient to disassemble. Meanwhile, the upper surface of the transition plug disc 6 can be completely embedded into the limiting disc 5 to form a gapless whole.

The wiring unit includes a bottom barrel 7, a first spring 8, a slant card 9, a top barrel 10, a contact pad 11, a second spring 12, a connection wire 13, a connection rod 14, and a connection ring 15. The inner bore diameters of the bottom barrel 7 and the top barrel 10 which are fixed with each other are the same.

As shown in fig. 3 and 4, a side hole is formed in the bottom tube 7, a first spring 8 is installed in the side hole, and an inclined clip 9 is movably installed through the first spring 8. The oblique clamp 9 is of a cylindrical structure as a whole, and one end facing the inner side of the bottom barrel 7 is of an oblique structure.

The top cylinder 10 is used for installing a wiring circuit, and a contact disc 11 is installed inside the top cylinder 10 to ensure the stability of the wiring. The lower surface of the contact disc 11 is the same shape as the upper surface of the limiting disc 5. The contact disc 11 is mounted by means of a second spring 12 which is fixedly mounted on the top cylinder 10, so that the mobility of the contact disc 11 is achieved. Meanwhile, the contact pad 11 is connected to a connection rod 14 and a connection ring 15 mounted on the top barrel 10 through a connection wire 13. The connection ring 15 functions as an external ground line connection.

The specific operating principle is as follows:

the grounding unit must first be screwed into the ground.

In the process of setting up the grounding circuit, the circuit to be grounded is now fixed on the connection ring 15. And manually sleeving the wiring unit and the grounding unit with each other. In the sleeving process, the inclined clamp 9 is extruded through the limiting disc 5, so that the first spring 8 is compressed. After the limiting disc 5 extends into the top barrel 10, the limiting disc 5 and the oblique clamp 9 form a stable clamping structure, so that the wiring unit and the grounding unit are kept stable. Meanwhile, the upper surface of the limiting disc 5 is in contact with the contact disc 11 to form a passage, and the grounding process is completed.

In-process is demolishd at ground connection line, the artifical wiring unit that pushes down, in the in-process of pushing down, slant card 9 can contact each other with the upper surface of transition plugboard 6, owing to be the slope structure, transition plugboard 6 can extrude slant card 9, and after transition plugboard 6 arranged in top cylinder 10, slant card 9 resets under the effect of first spring 8.
