Accompanying drawing explanation
Fig. 1 is the schematic perspective view that this utility model has connected；
Fig. 2 be this utility model earth terminal wire clamp with ground connection drill rod disassemble schematic diagram.
Reference: 1 insulating bar, 2 conductor wire end wire clamps, 3 short-circuit lines, 4 earth terminal wire clamps, 5 ground connection drill rods；41 wire clamps
Bolt, 42 attaching nuts, 43 locking nuts one；51 drill steels, 52 ground pricker bolts, 53 locking nuts two, 54 tap bore bit.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, 2, a kind of Portable short-circuit grounding wire device with low cost, include insulating bar 1, wire
End terminal 2, short-circuit line 3, earth terminal wire clamp 4, ground connection drill rod 5, conductor wire end wire clamp 2 is arranged on insulating bar 1 top, short-circuit line
3 one end connect conductor wire end wire clamps 2, short-circuit line 3 other end connect earth terminal wire clamp 4, earth terminal wire clamp 4 include cable clip bolt 41,
The attaching nut 42 coordinated with cable clip bolt 41, ground connection drill rod 5 includes drill steel 51, is welded on the ground pricker bolt on drill steel 51 top
52, ground pricker bolt 52 is connected with attaching nut 42.
In order to prevent attaching nut 42 from loosening, cable clip bolt 41 coordinates and is provided with locking nut 1, on ground pricker bolt 52
Coordinating and be provided with locking nut 2 53, ground pricker bolt 52 and attaching nut 42 are connected after putting in place, and locking nut 1 is resisted against
On attaching nut 42 inner face, locking nut 2 53 is resisted against on attaching nut 42 outer face.So two ends of attaching nut 42
Be locked nut 1 and locking nut 2 53 clamping and lock, it is to avoid attaching nut 42 loosen cause earth terminal wire clamp 4 with
Ground connection drill rod 5 in use disconnects.
In operation process, often run into multiple earth lead and share a ground connection drill rod 5, so ground pricker bolt (52) is set to
Multiple, they are welded on drill steel 51 along drill steel 51 circumference is uniform.Give over to standby additionally, arrange multiple ground pricker bolt 52, occur
Normal use is not interfered with when individually pricker bolt 52 damages yet.As preferably, ground pricker bolt 52 can be set to two.
In order to make ground connection drill rod 5 be easier to be tufted into ground, it is provided with cylindrical percussion bore bit 54 on the top of drill steel 51,
Further, described percussion bore bit 54 diameter of section is more than drill steel 51 diameter of section, thus makes bore bit 54 pricker bolt over the ground
52 have played protective effect, will not knock on ground pricker bolt 52 during percussion by mistake.
In order to make ground pricker bolt 52 more solid and reliable with the connection of attaching nut 42, attaching nut 42 length is more than locking
Nut 1 length；Additionally, cable clip bolt 41, the specification of pricker bolt 52 identical, locking nut 1, locking nut 2 53
Specification is identical, so can reduce manufacturing cost further.Cable clip bolt 41, pricker bolt 52 can select M12 × 70mm's
The full thread hexagon-headed bolt of 4.8 grades, through looking into hex nut standard GB/T41-2000, locking nut 1, locking nut 2 53
Length can be 12.2mm.
Operating process of the present utility model is as follows:
When using short circuit grounding line apparatus of the present utility model, first on the ground of operation field, hammer into ground connection drill rod 5；Again
On the ground pricker bolt that attaching nut 42 on earth terminal wire clamp 4 is connected on ground connection drill rod 5；Then locking nut 1 is screwed
With locking nut 2 53, make them respectively against on the end face of attaching nut 42 both sides so that attaching nut 42 is locked；Finally
Insulating bar 1 is used to be connected on each wire by conductor wire end wire clamp 2.
After the end of job, the process removing short circuit grounding line apparatus of the present utility model is contrary with aforementioned use process.
The beneficial effects of the utility model are:
The portable short-circuit grounding wire with low cost of this utility model structure, earth terminal wire clamp uses standard component with simple
Assembling structure, alligator clamp that alternative structure is more complicated or spiral top plate holder, it is achieved be reliably connected ground connection drill rod, reduce manufacture
Cost.
Above-mentioned detailed description of the invention is exemplary, is to more preferably enable those skilled in the art to understand and real
Execute this utility model, it is impossible to be not understood as the restriction to this utility model protection domain.As long as taken off based on this utility model
