Second townhouse mechanism is connect with the male connector, and the male connector of the anti-torsion plug mechanism is cylindrical metal；
The female is mutually fixed with the male connector by the first bolt.
Further, the female is mutually fixed with the male connector by the first bolt specifically:
Bolt hole is offered in the female two sides, first bolt is arranged in the bolt hole；The female is set
It is equipped with opening, the male connector is placed in the female opening；First bolt mutually fixes the female with the male connector.
Further, zinc coat is arranged in the external of the anti-torsion plug mechanism.
Further, zinc coat is set outside the steel strand wires.
Further, the first townhouse structure is mutually fixed with atural object waiting by the second bolt.
Further, the second townhouse structure is mutually fixed by third bolt with down conductor.
Further, the second townhouse structure is mutually fixed by welding with down conductor.
Further, the male connector shape of the anti-torsion plug mechanism is cylindrical body.
Implement the utility model, has the following beneficial effects:
By the utility model, anti-torsion plug mechanism is introduced, said mechanism when in use match by female and cylindrical metal
It closes and uses, do not influenced by torsion, in measurement of Grounding Resistance, male connector female is separated, because male connector is connect with the second townhouse structure,
It not will receive the influence that torsion and earth mat sink, can not be installed back after solving existing structure down conductor being caused to be removed
Go, need it is sawed-off weld again, costly, the problem of taking physical strength, low efficiency.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structure chart for the earthing or grounding means that the prior art provides.
Fig. 2 is the structure chart of earthing or grounding means provided by the embodiment of the utility model.
Fig. 3 is the female side view of anti-torsion plug mechanism provided by the embodiment of the utility model.
Specific embodiment
This patent core content is that down conductor and the have been isolated by anti-torsion plug mechanism and the second townhouse structure
The connection of one townhouse structure, when so that opening anti-torsion plug mechanism test ground resistance, anti-torsion plug mechanism is not under by grounding lead
The torsion that line and earth mat apply influences, and does furtherly below in conjunction with drawings and examples to the earthing or grounding means specific embodiment
It is bright.
A kind of earthing or grounding means embodiment provided by the utility model is described more fully below.
As shown in Fig. 2, the utility model embodiment provides a kind of earthing or grounding means, the earthing or grounding means includes the first townhouse knot
Structure 21, anti-torsion plug mechanism 22 and the second townhouse structure 23, in which:
Anti- torsion plug mechanism 22 includes female 221, male connector 222 and the first bolt, the first townhouse structure 21 and female 221
It is connected by steel strand wires, the second townhouse structure 23 is directly connect with male connector 222, and the male connector 222 is cylindrical metal, it is of course possible to
It is that cylindrical body is also possible to cuboid, the purpose using metal material is for conduction.
First townhouse structure 21 is mutually fixed by the second bolt with atural object waiting, and the second townhouse structure 23 passes through third spiral shell
Bolt is mutually fixed with down conductor, can also mutually be fixed by welding；Down conductor is connect with earth mat.
In the present embodiment, first, second, third, etc. it is not used in representative sequence, is mainly used for specification configuration and bolt.
When in use, the female 221 of anti-torsion plug mechanism is by unclamping the first bolt, for the public affairs of anti-torsion plug mechanism
First 222 insertion, 221 leaving space of female and gap, when male connector 222 is inserted into female 221, female 221 and male connector 222 pass through the
One bolt is mutually fixed；When carrying out ground resistance measurement, need to unclamp above-mentioned first bolt, so that ground resistance measuring device can
It is tested with directly passing through male connector 222, obtains resistance value, and this columnar metal body of male connector 222 is because of the second townhouse of connection
Structure, the torsion that not will receive down conductor and earth mat influence.
