Abstract
The utility model discloses an anti-dismounting nut and a wrench thereof. The outer side surface of the anti-dismounting nut is a revolution surface; more than two positioning grooves are formed on the outer end surface of the anti-dismounting nut; protrusions, of which the number is the same as that of the positioning grooves, are formed on the wrench in positions corresponding to the positioning grooves; the positioning grooves and the protrusions are matched with each other in shape; and the revolution surface is a linear or curve revolution surface. The anti-dismounting nut adopts a revolution body structure, and the side surface of the anti-dismounting nut is the revolution surface, so that a common wrench or a pipe wrench cannot dismount the nut. Aiming to solve the problem that a U-shaped/T-shaped nut between a stay wire and a ground anchor in a rural 10 KV distribution network is dismounted frequently in the background technology, the conventional common hexagonal nut is replaced by the anti-dismounting nut provided by the utility model, and the stay wire can be prevented from being disassembled by other people; and the anti-dismounting nut also can be used on an agriculture row transformer, so as to prevent the agriculture row transformer from being stolen.
Description
Technical field
The utility model relates to a kind of anti-disassembling nut and spanner thereof, particularly used UT type nut between backguy and the earth anchor in the distribution of 10KV rural area.
Background technique
The effect of backguy is the active force that is used for balance electric pole each side in the 10KV distribution, and opposing wind-force prevents that electric pole from toppling over.The backguy that in the 10KV distribution, plays balanced action mainly contains corner backguy, strain insulator backguy and terminal pole backguy, and playing the backguy of enhancing wind loading rating has the herringbone backguy.These backguys in the 10KV distribution usually place the farmland this trouble to be shown more for peasant's the big production of the trouble of bringing in various degree, particularly mechanization of cultivating, and artificial dismounting backguy behavior is of common occurrence.Its form of expression mainly contains: after removing backguy backguy is wrapped on the electric pole; UT type between backguy and the earth anchor is taken away.The consequence of removing backguy is that electric pole is toppled over, and crackle in various degree appears in electric pole what is more.Even if the network operation personnel once patrolled to the 10KV distribution in one month, this unsafe factor also still exists.When meeting with severse weather, the backguy after the dismounting might cause line-to-ground and short circuit under big wind action, even falls bar and broken string.These unsafe factors will bring a lot of economic losses to increase a lot of work also for simultaneously basic unit's power supply.
The model utility content
The utility model technical problem to be solved provides a kind of anti-disassembling nut and spanner thereof that plays the antitheft effect; It particularly is used UT type nut between backguy and the earth anchor in the 10KV distribution of rural area; Make people nut not to be disassembled, played the antitheft effect to a certain extent with common wrench.
For solving the problems of the technologies described above, the technological scheme that the utility model is taked is: a kind of anti-disassembling nut and spanner thereof, the outer side surface of said nut are turning surface, on the exterior edge face of said nut, are provided with plural positioning groove.
Corresponding position with said nut positioning groove on said spanner is provided with and the corresponding to convexity of said positioning groove quantity, and said positioning groove is suitable with protruding shape.
Said turning surface is straight line gyration face or curved-line surface of revolution.
Adopt the beneficial effect that technique scheme produced to be: the described anti-disassembling nut of the utility model has rotary structure; Its side is a turning surface; Make it all can not be disassembled with common spanner or pipe wrench; Problem to the UT type nut between backguy and the earth anchor in the rural area 10KV distribution of mentioning in the background technique often is disassembled with the original common hexagon nut of this anti-disassembling nut replacement of the utility model, can well prevent artificially to dismantle the behavior of backguy; Also can this anti-disassembling nut be used for farming row transformer simultaneously, can play a role the antitheft of transformer.

Embodiment
Like Fig. 1, shown in Figure 2, the outer side surface of the described anti-disassembling nut of the utility model is a turning surface, on the exterior edge face of said nut, is provided with plural positioning groove 1, and said turning surface is straight line gyration face or curved-line surface of revolution.
Like Fig. 3, shown in Figure 4; The corresponding spanner of the described anti-disassembling nut of the utility model; On said spanner, be provided with said positioning groove quantity corresponding to protrudingly 2 with the corresponding position of said nut positioning groove, said positioning groove 1 is suitable with protruding 2 shape.
Claims (3)
1. anti-disassembling nut, it is characterized in that: the outer side surface of said nut is a turning surface, at the positioning groove (1) that is provided with on the exterior edge face of said nut more than three.
2. a kind of anti-disassembling nut according to claim 1 is characterized in that: said turning surface is straight line gyration face or curved-line surface of revolution.
3. the corresponding spanner of an anti-disassembling nut; It is characterized in that: the corresponding position with said nut positioning groove on said spanner is provided with and the corresponding to convexity of said positioning groove quantity (2), and said positioning groove (1) is suitable with the shape of protruding (2).
