Abstract
The utility model discloses a stable-connection type ground rod, which comprises a ground rod main body. The lower end of the ground rod is provided with a conical head while the upper end is provided with a threaded segment. A striking head is arranged on the top of the threaded segment. A compression nut is screwed on the threaded segment. A pressing block movably sleeved on the threaded segment is located between the compression nut and the ground rod main body. The lower end face of the pressing block is provided with a wire duct for clamping a lead. The stable-connection type ground rod with a simple reasonable structure is convenient to install and use. By adopting a design characterized by the cooperation between the compression nut and the pressing block, the stable-connection type ground rod effectively facilitates lead connecting operations and achieves relatively good stability after the connecting operations. Connection states are not easily affected by construction. Contact failure phenomena are further prevented. The working efficiency is effectively increased. The ground protection safety factor is further enhanced.
Description
Technical field
The utility model relates to the used for transmission line earth protective device, is specially a kind of stable connection type earth rod.
Background technology
Power equipment and transmission line etc. often need to carry out ground protection, and earth rod arranges and connects the important medium that power equipment, transmission line are connected with the earth.And existing earth rod structure is reasonable not, it is convenient not with wire, to be connected, and easily causes wire and earth rod loose contact in work progress again after connecting, and then can not guarantee power equipment and transmission line are played to stable ground protection.
The utility model content
The purpose of this utility model is to provide a kind of stable connection type earth rod; reasonable not to solve earth rod structure traditional in prior art; it is convenient not with wire, to be connected; and easily cause wire and earth rod loose contact in work progress again after connecting, and then can not guarantee power equipment and transmission line are played the problem of stable ground protection.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of stable connection type earth rod, it is characterized in that: include the earth rod main body, described earth rod lower end is provided with conehead, upper end is provided with thread segment, described thread segment top is provided with attacking head, be screwed with clamp nut on described thread segment, be provided with activity between described clamp nut and earth rod main body and be nested with the briquetting on thread segment, described briquetting lower surface is provided with for tightening the wire casing of wire.
Described a kind of stable connection type earth rod, it is characterized in that: described attacking head is provided with the anti-skid wearable convex tendon.
The beneficial effects of the utility model are:
