Abstract
The utility model provides an anti-theft detachable grounding screw which comprises a nut and a screw rod. The outer surface of the nut is provided with a smooth ring, and an assembly and disassembly hole is arranged on the nut. The grounding screw can be prevented from losing, normal grounding resistance test cannot be affected, the grounding screw has a more effective function for ensuring safe operation of a circuit, the purposes of the grounding screw can be extended, and the grounding screw is mounted in other necessarily anti-theft places.
Description
Technical field
The utility model relates to a kind of grounding screw for electric transmission line, relates in particular to a kind of anti-theft detachable grounding screw.
Background technique
The electric transmission line grounding screw is lost seriously, the grounding screw that adopts is the plain edition screw at present, namely detachable with common spanner, and common spanner almost has in the every household, thereby increased the number of times of losing of grounding screw, indirectly electric transmission line is caused inevitable injury at thunderstorm season, more increased worker's workload.
Summary of the invention
The utility model provides a kind of anti-theft detachable grounding screw for above-mentioned problems of the prior art, has solved existing electric transmission line screw and has easily lost the unsafe problems of initiation.
The technical solution of the utility model is as follows:
Screw comprises nut and screw rod, and the outer surface of nut is smooth torus, and nut is provided with the dismounting hole.
Described dismounting hole is two holes that are oppositely arranged.
Spanner comprises handle and termination, and top, termination internal surface is provided with the fourth of the twelve Earthly Branches nail corresponding with nut dismounting hole.
The beneficial effects of the utility model are as follows:
Can prevent that grounding screw from losing, not affect normal earth resistance, play more effective effect for guaranteeing the line security operation.The purposes of extensible this kind screw is installed to other and is necessary to carry out antitheft place.
Description of drawings
Fig. 1 is the structural representation of the utility model screw.
Fig. 2 is the structural representation of the utility model spanner.
Among the figure, 1, nut, 2, screw rod, 3, the dismounting hole, 4, handle, 5, the termination, 6, fourth of the twelve Earthly Branches nail.
Embodiment
With reference to accompanying drawing, in conjunction with specific embodiments, the utility model is described in further detail.
Embodiment
As shown in Figure 1, screw comprises nut 1 and screw rod 2, and the outer surface of nut 1 is smooth torus, and nut 1 is provided with dismounting hole 3; Nut is by φ 30 * 15cm round steel, through centre punching, hitch, then stamps the aperture of two φ 4 at two relative opposing sides of annulus outer side surface; Screw rod is M16 * 35 screw rods.
As shown in Figure 2, spanner comprises handle 4 and termination 5, and termination 5 top internal surfaces are provided with the fourth of the twelve Earthly Branches nail 6 corresponding with nut dismounting hole, can insert in the hole, dismounting hole, nut both sides.
This nut integral body outside is disc, and therefore the normal activity spanner can't carry out because there not being fixing force bearing point
Installation and removal; When the installation and removal screw, the dismounting hole with outside the fourth of the twelve Earthly Branches nail insertion nut on spanner of the present invention top utilizes fourth of the twelve Earthly Branches nail and spanner inner circle tightening nut place stressed, rotating spanner, and nut rotates simultaneously, finally realizes the installation and removal of whole screw.Consider in actual applications, might ground wire or other reason the rotation of spanner is impacted, therefore each makes a call to a dismounting hole in the relative both sides of this nut, when running into obstacle, spanner can change to another dismounting hole and rotate.
