Specific embodiment
The utility model row is further described presently in connection with attached drawing.
As shown in Figures 1 to 4, a kind of anti-loose anti-theft nut, including nut body 1 and turning set are set on nut body 1
Nut set 2 be equipped with internal screw thread in connecting hole wherein being equipped with the connecting hole for connecting with screw rod in the nut body 1,
The cross section of the lateral wall of the nut set 2 is regular polygon structure more than conventional use of quadrangle in the prior art,
The cross section of the lateral wall of the set of nut described in the present embodiment 2 uses regular hexagon structure, in actual application process, ability
The technical staff in domain can be according to actual needs using the outer side wall structure of the conventional use of nut set of other prior arts；
Be equipped with gap 3 between the inner sidewall of lateral wall and the nut set 2 of the nut body 1, the nut body 1 it is outer
The opposite sides of side wall is equipped with the interior fixture block 4 being arranged along the axis direction of nut body 1, the interior fixture block 4 and nut sheet
Body 1 is an integral molding structure, and the lateral wall of the interior fixture block 4 is equipped with outer inclined-plane 5, and the nut covers the opposite of 2 inner sidewall
The sliding slot 6 of an axis direction setting along nut set 2 is respectively equipped at two sides and position corresponding with interior fixture block 4, it is described
The outer fixture block 7 that can be slided relative to sliding slot 6 is equipped in sliding slot 6, the side of close 6 slot bottom of sliding slot and cunning on the outer fixture block 7
It is fixedly connected between 6 slot bottom of slot by elastic component 8, the elastic component 8 can be elastic gum or spring, bullet in the present embodiment
Property part 8 be elastic gum, the other end of the outer fixture block 7 extends in gap 3, extends to one end in gap 3 on the outer fixture block 7
One side mutually abutted with the corresponding side surface of interior fixture block 4, the another side of one end in gap 3 is extended on the outer fixture block 7
Equipped with outer inclined-plane 9；
The end that the nut covers 2 one end is fixedly welded with the outer cover 10 of a ring structure, the inner ring of the outer cover 10
Diameter is less than the outer annular diameter of nut body 1 and is greater than the annular diameters of nut body 1, so that outer cover 10 can be by nut
Gap 3 between ontology 1 and nut set 2 covers, it is notable that is manufacturing between the outer cover 10 and nut body 1
Unconnected state, in order to be able to carry out relative rotation between nut body 1 and nut set 2；
One end end on the nut body 1 far from outer cover 10 is equipped with a circumferential direction along nut body 1 and sets
The card slot 11 set, the nut, which covers, is equipped with the snap ring 12 to match with card slot 11,12 He of snap ring close to one end of card slot 11 on 2
It is clearance fit between card slot 11.
The use principle of the utility model is summarized as follows:
When the utility model is installed (it is worth noting that during installation should be by outer cover 10 towards outside), pass through external key
Positive turn nut set 2, the outer fixture block 7 that nut covers in 2 is mutually abutted with the interior fixture block 4 on nut body 1, to drive nut body
1 rotating forward is tightened against on screw rod；Wherein antitheft principle are as follows: after this practical new rotating forward is tightened, nut is inverted by spanner
Set 2, the outer inclined-plane on outer fixture block 7 is mutually abutted with the outer inclined-plane 5 on interior fixture block 4 at this time, and outer inclined-plane 5 is pushed by outer inclined-plane 9
Outer fixture block 7 squeezes elastic component 8 and outer fixture block 7 is slided into sliding slot 6, so that being unable to drive nut body 1 carries out reversion release,
And then achieve the effect that antitheft.
