Abstract
The utility model relates to an anti-theft nut, which comprises a nut body, wherein, the inner wall of the nut body is provided with inner screw threads. Along the circumferential direction of an inner hole, one end of the nut body is provided with a plurality of wedge-shaped grooves for containing roller balls, and the size of each of the wedge-shaped grooves is corresponding to the diameter of each of the roller balls. One the other end of the nut body, the outside of each of the wedge-shaped grooves is provided with a step which is matched with a plastic pad of each of the wedge-shaped grooves for a sealing cap. Each of the wedge-shaped grooves can be divided equally into two or three or more wedge-shaped grooves along the circumferential direction, and each of the wedge-shaped grooves can also be a single wedge-shaped groove. The utility model has the advantages that due to the use of the wedge-shaped grooves and the match of the wedge-shaped grooves and the roller balls, the purpose of tight clamp and anti-loose is achieved. Thus, the utility model is simple in structure, convenient in use, and reliable in performance.
Description
Technical field
The utility model relates to a kind of fastening piece, mainly is a kind of anti-theft nut.
Background technique
At present, power transmission and transformation post and telecommunications, iron tower, bridge and highway barrier and various unserviced open-air job facilities all need to prevent to become flexible and prevent the artificial fastening occasion of dismantling.And present fastening piece is scarcely antitheft, has the structure of anti-theft feature to improve on screw rod mostly, increases structures such as pin or groove, and the deficiency of its structure is: cost is higher, uses inconvenient.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, prevents loosening and prevents the anti-theft nut of artificial dismounting and provide a kind of.
The purpose of this utility model is achieved through the following technical solutions.This anti-theft nut, it comprises nut body, and the inwall of nut body is provided with internal thread, is provided with some wedge slots that are used to lay ball at an end of nut body along the circumferencial direction of endoporus, and the size of wedge slot and the diameter of ball adapt.
The utility model can come further perfect by the following technical programs.At an end of nut body, the outside of wedge slot is provided with a step, matches with the plastic mattress of capping wedge slot.Described wedge slot can be 2,3 and a plurality of wedge slot along the circumference five equilibrium.Described wedge slot also can be single wedge slot.
The effect that the utility model is useful is: owing to adopted wedge slot, wedge slot and ball cooperate, and reach the locking purpose of chucking; Therefore structure is simpler, easy to use and reliable performance.

Embodiment
Below in conjunction with embodiment the utility model is further described.
This anti-theft nut, it comprises nut body 1, and the inwall of nut body 1 is provided with internal thread 3, is provided with three wedge slots 6 that are used to lay ball 2 at an end of nut body 1 along the circumferencial direction of endoporus, and wedge slot 6 is three wedge slots 6 along the circumference five equilibrium.The diameter of the size of wedge slot 6 and ball 2 adapts, 6 one of wedge slots are big, one little, big diameter than ball 2 more greatly, little diameter is more a little bit smaller than ball 2.At an end of nut body 1, the outside of wedge slot 6 is provided with a step 7, matches with the plastic mattress 5 of capping wedge slot 6.
During installation: can increase the accessory (plastic sheath 4) that is used to install, plastic sheath 4 is installed in earlier in the nut body 1, respectively puts into a ball 2 in three wedge slots 6, covers plastic mattress 5, prevents that ball 2 from dropping out.Then nut precession on the bolt 8 is gone, plastic sheath 4 is ejected because 6 one of wedge slots are big, one little, ball 2 was stuck in major part when precession was gone, therefore precession is gone easily; Ball 2 is stuck in the microcephaly when screwing out, and therefore is stuck and does not revolve not.Realize antitheft and locking purpose.
