Abstract
The utility model discloses a grounding device ensuring good electric contact. The grounding device comprises a strip-shaped rod body (1). A tip (2) is arranged on one end of the rod body (1), and a hand (3) is arranged on the other end. An access block (4) is welded at the position close to the handle (3) on the rod body (1). A screw (5) is arranged on the access block (4). The screw (5) is screwed with a nut (6). The grounding device provided by the utility model has the advantages that the screw and the nut are arranged; a grounding wire is pressed on an access board; the access board is welded and connected with the rod body, which ensures the contact of the grounding wire and the ground; a spiral groove is arranged on the lower end of the rod body; and the rod body is inserted into the earth, which is labor-saving.
Description
Technical field
The utility model relates to a kind of earthing device, and specifically ground stud particularly relates to the earthing device of guaranteeing excellent electric contact.
Background technology
At present, in electric power system, the ground stud using is all a steel rod, one end arranges tip, inserts undergroundly by tip, and earth connection is wrapped in the one end of basseting, but this canoe, earth connection was easy to unclamp with being connected of ground stud, caused ground connection unsuccessful, may cause the accident that is difficult to expectation.
Utility model content
The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, and the earthing device of guaranteeing excellent electric contact is provided, solve existing ground stud be connected with earth connection not firm, the defect of easily unclamping.
The purpose of this utility model is achieved through the following technical solutions: the earthing device of guaranteeing excellent electric contact, comprise a body of rod that is strip, described body of rod one end arranges tip, the other end arranges handgrip, on the body of rod, near the position of handgrip, be welded with an access piece, on described access piece, be provided with a screw rod, on screw rod, be connected with a nut.A screw rod is set in this device, earth connection is wrapped on screw rod, then by nut, compress, guaranteed that earth connection and ground stud have good electrically contacting, also avoided earth connection to come off from ground stud, guaranteed staff's safety work.
Further, one end that tip is set on the above-mentioned body of rod is provided with groove, described groove on the body of rod from tip to handgrip direction spiral extension.Groove is set, when the body of rod is inserted earthward, has reduced the extruding to earth, reduced resistance, facilitate the body of rod to be inserted in ground, and spiral helicine groove, when the body of rod is difficult to directly vertically insert earth, can, in the mode of turn, insert effortlessly in ground.
Further, above-mentioned handgrip is vertical bar shape, and it is perpendicular to the body of rod, and the tie point of handgrip and body of rod termination is positioned at the center of handgrip.Handgrip is provided with symmetrical vertical bar shape, and staff can with the hands hold respectively handgrip two ends the body of rod is inserted in earth, also facilitates the turn body of rod, in the mode of turn, the body of rod is inserted in earth.
Further, on above-mentioned screw rod, away from one end of access piece, be fixed with a baffle ring, during production, first by nut on screw rod, then baffle ring is spun on screw rod end, then welds, and guarantees fixingly, baffle ring and access board are stuck in nut on screw rod.
The beneficial effects of the utility model are: screw rod and nut are set, earth connection is pressed on access board, access board and the body of rod are welded to connect, and have guaranteed contacting of earth connection and ground; Body of rod lower end is provided with spiral helicine groove, when the body of rod inserts in earth, more laborsaving.
