Detailed Description

The invention is explained in more detail below with reference to the figures and examples.

Referring to fig. 1-4, embodiments of the present invention provide the following technical solutions: the utility model provides a novel earth bar, includes barred body 1, and barred body 1's surface is provided with first external screw thread 2, and cardboard 3 has been cup jointed on barred body 1's surface, and spacing collar 4's surface thread is connected with set screw 5, and barred body 1's fixed surface installs wiring end 6, and the internal thread of wiring end 6 is connected with line ball screw 7, and the lower surface of wiring end 6 is provided with LED lamp 8, and protective housing 9 has been cup jointed on barred body 1's surface.

In this embodiment: still include through being provided with cardboard 3, when installing this earth bar, can push down sharp awl department with cardboard 3 and insert in order fixed, make this earth bar be difficult for rocking, greatly improved the fixity, through spacing collar 4 cooperation fixed screw 5, spacing collar 4 can prevent it from breaking away from ground in cardboard 3 top, screw up fixed screw 5, make its one end support to barred body 1 to fixed spacing collar 4 makes spacing collar 4 play fixed effect.

In this embodiment: through being provided with line ball screw 7, can press the one end of earth connection fixedly, make it difficult not hard up, avoid appearing the electric shock accident, through being provided with protective housing 9, can play dustproof and waterproof's effect, the material of protective housing 9 is insulating material, and protective housing 9 can reach fixed position through supporting the board, can not direct contact line ball screw 7, through bolt 10 cooperation nut 11, can hoist cardboard 3 fixedly, cardboard 3 can be along with the rotatory barred body 1 of operator and rotatory together when preventing to install barred body 1, through cylinder 12 cooperation second external screw thread 13, can alleviate the resistance between barred body 1 and the soil, interval between every cylinder 12 equals, partial soil can gather between two cylinders 12, avoid soil to pile up in screw thread department and cause great resistance to barred body 1.

Specifically, the method comprises the following steps: a bolt 10 is inserted into the surface of the protective shell 9, and one end of the bolt 10 is connected with a screw cap 11 in a threaded manner; therefore, the clamping plate 3 can be lifted and fixed by matching the bolt 10 with the nut 11, the clamping plate 3 is prevented from rotating together with the rotating rod 1 of an operator when the rod 1 is installed, and the lifting height of the clamping plate 3 can be adjusted by screwing the nut 11.

Specifically, the method comprises the following steps: one end of the rod body 1 is fixedly provided with a column body 12, and the surface of the column body 12 is provided with a second external thread 13; therefore, the columns 12 are matched with the second external threads 13, so that the resistance between the rod body 1 and soil can be reduced, the distance between every two columns 12 is equal, part of soil can be gathered between the two columns 12, and the soil is prevented from accumulating at the threads to cause large resistance to the rod body 1.

Specifically, the method comprises the following steps: a drill bit 14 is fixedly arranged at one end of the rod body 1, a third external thread 15 is arranged on the surface of the drill bit 14, and a handle 16 is fixedly arranged at one end of the rod body 1; therefore, the sharp part at one end of the drill bit 14 can be directly inserted into the ground, and the drill bit can be more easily drilled into the soil by rotating the drill bit through the third external thread, so that the working efficiency is improved, the working time is saved, and the handle 16 can enable an operator to rotate the rod body 1 more conveniently and more labor-saving.

The working principle is as follows: when the grounding rod is used, the grounding rod is inserted into the ground, the drill bit 14 firstly enters the soil, then the drill bit 14 is screwed into the deeper part through the third external thread 15 by rotating the handle 16, then the plurality of columns 12 enter the soil one by one through the second external thread 13, the distance between every two adjacent columns 12 is equal, therefore, part of the soil can be gathered between the adjacent columns 12, and the handle 16 is rotated until the first external thread 2 completely enters the soil; then break away from bolt 10 with nut 11, extract bolt 10 and make cardboard 3 erect subaerial, then insert every sharp-pointed department of cardboard 3 ground with fixed, then lift protective housing 9, pass through line ball screw 7 with the one end of earth connection fixed, the electrically conductive core of the inside of wiring end 6 directly links to each other with the sharp-pointed department of drill bit 14, and the earth connection circular telegram back, LED lamp 8 can light the instruction.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
