Abstract
The utility model discloses a circular combined type antitheft nut, including the nut body, nut body lower part is circular structure, and the outside arch in upper portion has the prism structure, and middle opening there is the screw, it has one section convex theftproof groove to open on the screw lateral wall, the theftproof inslot is equipped with dog, spring and steel ball, and the spring is established between dog and steel ball, be equipped with the moment of torsion recess that the diameter is greater than the screw diameter in the structural side of prism. The utility model has the advantages of it is following: have simple structure, the nut is unable dismantles the effectual advantage of locking theftproof through external force.
Description
Technical field
This utility model is related to power grid iron tower technical field of construction equipment, especially a kind of circular Combined theft-proof nut.
Background technology
Anti-theft nut is difficult stolen effect mainly for the protection of high voltage iron tower electrical equipment.Existing anti-theft nut is mostly
Original nut interior opens up wedge shape Anti-theft groove, and steel ball and spring are provided with Anti-theft groove, outside for prismatic structure, this spline structure
Anti-theft nut have the shortcomings that Anti-theft groove processed complex, nut can by external force force dismantle.
Utility model content
This utility model is directed to the deficiencies in the prior art, proposes a kind of circular Combined theft-proof nut, simple structure, nut
Cannot be dismantled by external force, anti-loose anti-theft effect is good.
In order to realize above-mentioned utility model purpose, this utility model provides technical scheme below：A kind of circular combined type is prevented
Steal nut, including nut body, the nut body bottom is circular configuration, top outwardly convex has prismatic structure, and centre is opened
There is screw；One section of circular arc Anti-theft groove is provided with the wall of the screw side, block, spring and steel ball, bullet in the Anti-theft groove, is provided with
Spring is located between block and steel ball；The moment of torsion groove with diameter greater than screwhole diameter is provided with the prismatic structure upper side.
Further, also including antitheft circle, antitheft circle is annular shape, is set in outside circular configuration.
Further, the height of the prismatic structure for nut body height 1/1 to five/3rds.
Further, a circle torsional channel is provided between the prismatic structure and the screw.
Compared with prior art, this utility model has advantages below：With simple structure, nut cannot be torn open by external force
Unload, the good advantage of anti-loose anti-theft effect.

Fig. 1 is structural representation of the present utility model；
Fig. 2 is tangent plane structural representation of the present utility model；
Fig. 3 is the structural representation that this utility model is torsional channel；
Fig. 4 is the tangent plane structural representation that this utility model is torsional channel；
Wherein：1 nut body, 2 circular configurations, 3 prismatic structures, 4 screws, 5 Anti-theft grooves, 6 blocks, 7 springs, 8 steel balls, 9
Moment of torsion groove, 10 antitheft circles, 11 torsional channels.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described in detail, the description of this part be only it is exemplary and explanatory,
There should not be any restriction effect to protection domain of the present utility model.
As illustrated in fig. 1 and 2：A kind of circular Combined theft-proof nut, including nut body 1, it is characterised in that：Described spiral shell
1 bottom of maternal body is circular configuration 2, and top outwardly convex has prismatic structure 3, and centre is provided with screw 4, in the middle of described screw 4
Circular arc Anti-theft groove 5 is provided with, block 6, spring 7 and steel ball 8 is installed in described Anti-theft groove 5, is arranged on described block 6
7 one end of spring, described 7 other end of spring are provided with steel ball 8, are provided with diameter greater than 4 diameter of screw in the middle part of described prismatic structure 3
Moment of torsion groove 9.
Described 1 bottom of nut body is provided with the antitheft circle 10 for coordinating circular configuration 2, and described antitheft circle 10 is enclosed within circle
In structure 2.
The height of described prismatic structure 3 is between 1st/1 to five/3rds of 1 height of nut body.
As shown in Figures 3 and 4, a kind of circular Combined theft-proof nut, is provided with one between described prismatic structure 3 and screw 4
Circle torsional channel 11 so that 4 height of screw keeps constant, so as to ensure the fastening force of nut.
When in use：Antitheft circle 10 is enclosed within into 1 bottom of nut body, 1 top of nut body is pulled using general tool
Prismatic structure 3, carries out fastening installation, when torsional forces reaches to a certain degree, using moment of torsion groove 9 or torsional channel 11 so that prismatic
Structure 3 is deformed, and fastening tool is released, and plays a part of to determine moment of torsion, anti-loose anti-theft.
Antitheft circle is enclosed within into nut body bottom when in use, the prismatic knot on nut body top is pulled using general tool
Structure, carries out fastening installation, when torsional forces reaches to a certain degree, using moment of torsion groove or torsional channel so that prismatic structure produces change
Shape, fastening tool are released, and play a part of to determine moment of torsion, anti-loose anti-theft.
A kind of circular Combined theft-proof nut of this spline structure has simple structure, and nut cannot be dismantled by external force, prevents
The advantage of loose good anti-theft effect.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model principle, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
