Abstract
The utility model relates to a ground rod: one end of a long and thin shaft is provided with a cone-shaped ground head and the other end of the long and thin shaft is provided with a through hole for being connected with an earth lead; the long and thin shaft is a threaded rod at the end where the through hole is arranged; the two sides of the through hole are provided with compression nuts. The utility model has the advantages that: as the earth lead runs through the through hole and is fixed on the ground rod by using the compression nuts, the connection is reliable; in addition, the earth lead has a wider range of diameter.
Description
Technical field:
The utility model relates to a kind of electric armour clamp, relates in particular to a kind of earth rod.
Background technology:
As everyone knows, the earth rod that is used for electric power system is that the end at slender axles is provided with coniform ground connection head, the other end at slender axles is provided with the through hole that connects earth lead, earth lead is tightened on the earth rod after passing through hole, this structure exists and connects insecure shortcoming, the earth lead that adopts this mode to connect in addition too carefully can be twisted not tight, too slightly can twist motionlessly, and the size of its diameter is subjected to certain restriction.
Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of connection reliable earth rod.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: earth rod, end at slender axles is provided with coniform ground connection head, the other end at slender axles is provided with the through hole that connects earth lead, the end that slender axles are provided with through hole is one section screw rod, is provided with clamp nut in the both sides of through hole.
As further improvement, the polished rod of slender axles part is identical with the diameter of screw portion.
The beneficial effects of the utility model: because earth lead is fixed on the earth rod with clamp nut after passing through hole, thereby has the reliable advantage of connection, in addition, the diameter range of earth lead is bigger.Also have screw portion to adopt the thread rolling processes, the diameter before processing is less than the polished rod part, and processing back diameter is identical, the advantage of have good looking appearance, saving material.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model is further described:
As shown in Figure 1, earth rod is provided with coniform ground connection 2 at an end of slender axles 1, is provided with the through hole 3 that connects earth lead at the other end of slender axles 1, and the end that slender axles 1 are provided with through hole 3 is one section screw rod 4, is provided with clamp nut 5 in the both sides of through hole 3.
The polished rod part of slender axles 1 is identical with the diameter of screw portion.
Claims (2)
