Abstract

The utility model discloses a grounding rod. The bottom of a steel rod is molded into a subulate head, the outer side of the steel rod body is sheathed with a copper sheet tube, the outer side of the subulate head is sheathed with a subulate stainless steel coat, the hemline of the stainless steel coat is molded into an annular extending section, the stainless steel coat is prefilled with waterproof electric filling glue, and the extending section is sheathed at the outer side of the bottom end of the copper sheet tube. The space between the stainless steel coat and the outer sides of the subulate head and the bottom end of the copper sheet tube is filled with the waterproof electric filling glue so that no interspace exists, which achieves the effects that the subulate head is not corroded, the glued copper sheet tube does not slip, and products are simply processed.

Description

Earth rod

The utility model relates to a kind of earth rod, mainly have do not peel, incorrosive characteristic, can guarantee that the life-span of earth rod is more permanent.

The earth rod summary of commonly using can be divided into three kind, and one is to form a cone-shaped head A1 in rod iron A bottom as shown in Figure 4, answers in the barred body outside with plating mode plating one deck copper sheet A2; It is two as Fig. 4, and copper sheet only pull coats, and very easily comes off during construction, and copper rod is perishable, and the ground connection effectiveness time limit is very short; It three then as shown in Figure 5, form a cone-shaped head B1 equally in rod iron B bottom, but make the maximum gauge of cone-shaped head B1 form a scalariform block B2 greater than the external diameter of barred body part, be overlying on the barred body external diameter and establish the groove B3 of guiding principle shape, cross-like or other shapes, and coat a copper sheet pipe C in barred body bag portion, make the bottom of copper sheet pipe C just be butted on scalariform block B2 place, and copper sheet pipe C inner tube surface is snapped at the groove B3 of barred body to prevent copper sheet pipe C slippage; So, preceding three kind commonly use earth rod actual use and make still have such as: shortcoming such as make to be difficult for, copper sheet Guan Yi comes off and rod iron is perishable, this is now in hereinafter doing a detailed description.

At first with regard to the structure of Fig. 4, because the copper sheet A2 of rod iron A barred body outside is by the plating mode plating, though its copper sheet A2 thickness is thin, when being inserted in ground, still not having copper sheet A2 and comes off, promptly be commonly called as the phenomenon of " decortication ", but, in manufacture process, because of the need plating step, be difficult for processing, and, be inserted in ground after just have oxidation after a while because of its cone-shaped head A1 is directly made by steel, corrosion phenomenon produces, if not the face plating mode, with only pull lining of copper sheet, after then it was inserted in ground, copper sheet very easily came off, and then exposed copper rod is the ground connection weak effect not only, more perishable, reduce the life-span; Study the structure of Fig. 5 again, by diagram as can be known the cone-shaped head B1 of this rod iron B be not easy processing making, and its steel toe also has the problem of oxide etch, and then influences the ground connection effect of earth rod.

Combine the above-mentioned explanation of collection, the disadvantage of commonly using product as can be known is to be:

1, the head of rod iron is exposed to the external world, easily produces oxidation, corrosion, influences the life-span of earth rod;

2, the easy landing of copper sheet pipe of copper rod barred body outside influences the conductive effect of ground connection;

3,,, increase the inconvenience of making in the processing because of electroplating process though can overcome the fraud of " decortication " if adopt plating mode plating copper sheet.

The purpose of this utility model then provides a kind ofly to be convenient to make and the unlikely generation copper sheet of product comes off or the earth rod of phenomenon such as rod iron corrosion.

Cause above-mentioned purpose for reaching, the utility model forms a cone-shaped head in rod iron body bottom, and in the outside copper sheet pipe that coats of barred body, a cone-shaped stainless steel sleeve is covered in the outside of cone-shaped head, the root edge of this stainless steel sleeve and moulding one ring extension make the extension just can be coated on outside, copper sheet pipe bottom, and are perfused with waterproof conductive fill glue in advance in cone-shaped stainless steel sleeve inside, it riddles between the cone-shaped head of stainless steel sleeve, outside, copper sheet pipe bottom, forms to prevent the conductive fill glue-line.

In addition, after stainless steel sleeve of the present utility model is sheathed on cone-shaped head, also can carry out punching press, make the extension cave in being snapped at the outside of copper sheet pipe bottom, advance a protection rod iron, prevent that stainless steel sleeve from coming off in extension place.

After adopting said structure, the utility model utilizes the stainless steel sleeve protection and every the cone-shaped head of structure rod iron, makes its unlikely generation oxidation, corrosion, can prolong its useful life; Utilize stainless steel sleeve interlock copper sheet pipe again, make its unlikely landing, can keep the ground connection conductive effect of earth rod; In addition, the utility model manufacturing processing is easy, does not need to electroplate separately or the moulding groove, effectively simplifies procedure of processing and process.

Below in conjunction with graphic and embodiment the utility model is further described.

Fig. 1 is an exploded view of the present utility model;

Fig. 2 is an assembled sectional view of the present utility model;

Fig. 3 is an enforcement illustration of the present utility model;

Fig. 4 is a cutaway view one of commonly using product;

Fig. 5 is a cutaway view two of commonly using product.

See also Fig. 1,2, the utility model comprises a rod iron 1, a copper sheet pipe 2 and a stainless steel sleeve 3, wherein rod iron 1 is a barred body, form a cone-shaped head 11 in the bottom, copper sheet pipe 2 then is coated on outside the barred body of rod iron 1 in the pull mode of undergauge, make copper sheet pipe 2 bottoms just be placed in cone-shaped head 11 places, and stainless steel sleeve 3 is cone-shaped cap bodies, in the root edge and the moulding one ring extension 31 of this stainless steel sleeve 3, an amount of waterproof conductive fill glue 32 of the pre-perfusion in the inside of stainless steel sleeve 3; Make stainless steel sleeve 3 be sheathed on outside the cone head 11 of rod iron 1, and pressing it, make extension 31 be coated on the copper sheet pipe 2 bottoms outsides, between waterproof conductive fill glue 32 then is filled in outside stainless steel sleeve 3 and cone-shaped head 11, copper sheet pipe 2 bottoms.

Thus, utilize stainless steel sleeve 3 that the cone-shaped head 11 of rod iron 1 is hedged off from the outer world, can prevent effectively that steel from producing oxidation, corrosion; And utilize stainless steel sleeve 3 to be sleeved on copper sheet pipe 2 bottoms, can when earth rod plugs, prevent the landing of copper sheet pipe 2.

Moreover; the utility model is except that utilizing waterproof conductive fill glue 32 glues together; also can be after stainless steel sleeve 3 be sheathed on cone-shaped head 11; 31 places carry out punching press in the extension; making it cave in is snapped at copper sheet and overlaps 2 bottoms; as shown in Figure 3, have protection steel and prevent the effect that copper sheet pipe 2 comes off equally.

Claims

1, a kind of earth rod, form a cone-shaped head in a rod iron bottom, and in the outside copper sheet pipe that coats of barred body, it is characterized in that: cone-shaped head cover covers a cone-shaped stainless steel sleeve, the root edge of this stainless steel sleeve and moulding one ring extension, this extension just is coated on outside, copper sheet pipe bottom, and in cone-shaped stainless steel sleeve internal preset waterproof conductive fill glue-line is arranged.
