The fixed tool of kind, there is hole at center, has screw thread on the inside of hole.The screw that nut is often harmonious with size shares, to be fixed with
The engagement part of pass.Acorn nut is one of nut, and acorn nut is exactly as its name suggests hex nut with a lid, this
Lid its effect be exactly fastening outside expose part cover, prevent moisture or some other corrosive substance enter the inside to
Play the role of antirust, and then improves the use time of itself and connector, but the anti-theft performance of existing acorn nut is not
Good, existing acorn nut is easy to just to be disassembled, and be easy to cause economic loss, and some privileged sites need antitheft component,
Existing acorn nut is unable to satisfy.
[summary of the invention]
The object of the invention is to solve the problems of the prior art, a kind of cap nut that anti-theft performance is good, energy are proposed
The anti-theft performance of nut is enough improved, nut is just difficult to be disassembled once installation, improves safety.
To achieve the above object, the cap nut good the invention proposes a kind of anti-theft performance, including nut body, nut
Upper cover, nut tightening piece twist into two parts connector, and the nut body is the cylindrical type of smooth outer surface, the nut body
Interior center is equipped with nut internal screw thread connecting cavity, and the nut body upper end is equipped with nut upper cover, and the nut upper cover is half
Ball-type, the nut upper cover upper end, which is equipped with, twists into two parts connector, and described twists into two parts connector upper end equipped with nut tightening piece.
Preferably, the described connector of twisting into two parts is rounding bench-type, it is described twist into two parts connector lower end and nut upper cover it
Between connection area be less than and twist into two parts connection area between connector upper end and nut tightening piece.
Preferably, most thin for the diameter of whole nut at the tie point twisted into two parts between connector and nut upper cover
Place, it is described nut is tightened between part and nut upper cover connection twists into two parts required torsion is greater than will be between nut body and bolt
Tighten required torsion.
Preferably, the nut tightening piece upper end is equipped with the spanner wild card oral area that can cooperate with bayonet spanner, institute
The spanner outer bayonet cross section stated is regular hexagon or regular quadrangle.
Preferably, the nut tightening piece upper end center is equipped with the allen wrench that can cooperate with allen wrench
Bayonet chamber.
Preferably, the nut body, nut upper cover, nut tightening piece, twisting into two parts the center of connector in same
On axis, the nut body, nut tightening piece, twists into two parts connector coaxial arrangement at nut upper cover.
Preferably, being integrally formed between the nut body and nut upper cover.
Preferably, the nut tightening piece and twisting into two parts is integrally formed between connector.
A kind of cap nut that anti-theft performance is good of the present invention the utility model has the advantages that the present invention by the way that the setting of nut upper end is twisted into two parts
Connector and nut tightening piece, turn nut by nut tightening piece, after nut is tightened, continue to turn nut tightening piece,
Until the connection twisted into two parts between connector and nut upper cover disconnects, there is no place that can come with stress without the nut of nut tightening piece
Nut is opened, nut is just difficult to be disassembled once installation, improves safety, improves anti-theft performance, and production cost is low.
Feature and advantage of the invention will be described in detail by embodiment combination attached drawing.
