For irony needle, irony needle electric conductivity it is poor, using effect is bad, meanwhile, irony needle be easy corroded, substantially reduce
Its service life, for above situation, it is proposed that a kind of porous copper ground needle.
Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and a kind of porous copper proposed
Needle.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of with designing porous copper needle, including shell, the shell are hollow structure, and the lower end of the shell is equipped with
Cone, the surface of the shell are equipped with multiple protrusions, and the inside of the protrusion is equipped with the groove communicated with shell inside, described
The upper end internal screw thread of shell is connected with the second stud, and the upper end of second stud is equipped with limit plate, the limit plate it is upper
Surface is equipped with the first stud, and push plate is socketed on the outside of first stud, and a upper lateral part of the push plate is equipped with connection
Bar, the upper end of the connecting rod are equipped with pressing plate, and the outside screw of first stud is connected with the nut above push plate.
Preferably, the middle part of the pressing plate is equipped with horizontal through-hole, and the upper surface of the pressing plate is threaded with and through-hole
The screw communicated.
Preferably, it is structure as a whole between the cone and shell.
Preferably, the material of the shell, cone, the second stud, the first stud and limit plate is copper.
Preferably, it is structure as a whole between second stud, the first stud and limit plate.
The utility model proposes a kind of porous copper needle, beneficial effect be: the utility model use copper product, energy
Electrical efficiency is enough greatly improved, while shell is hollow structure, injects salt water in shell, and can further increase its conduction
Property, the protrusion of case surface is capable of increasing the contact area with ground, on the one hand makes the bonding strength on ground needle and ground higher, separately
On the one hand it can be improved again between ground needle and ground and pass to effect, compared to the prior art, structure is simple for the utility model, makes
With conveniently, conductive effect is good, and stability is strong, and be worth promoting use.
Detailed description of the invention
