The nut is the part that links up mechanical equipment zonulae occludens, and through the inboard screw thread, equal specification nut and bolt just can link together, and the theory of operation of nut adopts the frictional force between nut and the bolt to carry out the auto-lock, and current nut does not possess the theftproof function mostly, and ordinary spanner just can pull down the nut, leads to the article of fastening to lose like this easily.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a nut of theftproof possesses the theftproof function, and single ordinary spanner can not pull down the nut, prevents to fasten the advantage that article lost, has solved current nut and has mostly not possessed the theftproof function, and ordinary spanner just can pull down the nut, leads to easily fastening the problem that article lost.
In order to achieve the above object, the utility model provides a following technical scheme: the anti-theft nut comprises a nut body, wherein a connecting sleeve is welded at the top of the nut body, a dismounting nut is sleeved on the outer surface of the connecting sleeve, and right-handed threads are arranged in the inner cavities of the nut body and the connecting sleeve.
Preferably, the nut for dismounting comprises a nut body, a cavity is formed in the nut body, a supporting spring is movably connected to an inner cavity of the cavity, a movable plate is fixedly connected to one side, opposite to the supporting spring, of the left side and the right side, a limiting strip is welded to one side, away from the supporting spring, of the movable plate, and the inner cavity of the nut body is penetrated through to one side, away from the movable plate, of the limiting strip.
Preferably, the bottom of the limiting strip is provided with a chamfer, the number of the cavities is four, and the surface of the limiting strip is connected with the joint of the nut body in a sliding manner.
Preferably, the connecting sleeve comprises a sleeve body, the outer surface of the sleeve body is provided with four limiting sliding grooves, and the four limiting sliding grooves are uniformly distributed on the periphery of the outer surface of the sleeve body.
Compared with the prior art, the beneficial effects of the utility model are as follows:
the utility model discloses a cooperation of nut body, right-handed thread, nut body, spacing, supporting spring, fly leaf, cavity, sleeve pipe body and spacing spout is used, possesses the theftproof function, and single ordinary spanner can not pull down the nut, prevents to be fastened the advantage that article lost, is worth promoting.

In the figure: the nut comprises a nut body 1, a dismounting nut 2, right-handed threads 3, a nut body 4, a limiting strip 5, a supporting spring 6, a movable plate 7, a cavity 8, a connecting sleeve 9, a sleeve body 10 and a limiting sliding groove 11.
Detailed Description
Referring to fig. 1-5, an anti-theft nut includes a nut body 1, a connecting sleeve 9 welded on the top of the nut body 1, a detachable nut 2 sleeved on the outer surface of the connecting sleeve 9, and right-handed threads 3 respectively disposed in the inner cavities of the nut body 1 and the connecting sleeve 9;
the dismounting nut 2 comprises a nut body 4, a cavity 8 is formed in the nut body 4, a supporting spring 6 is movably connected to the inner cavity of the cavity 8, a movable plate 7 is fixedly connected to one side of the movable plate 7, which is far away from the supporting spring 6, a limiting strip 5 is welded to one side of the movable plate 7, which is far away from the movable plate 7, and the side of the limiting strip 5, which is far away from the movable plate 7, penetrates through the inner cavity of the nut body 4;
the bottom of the limiting strip 5 is provided with a chamfer, the number of the cavities 8 is four, and the surface of the limiting strip 5 is in sliding connection with the joint of the nut body 4;
connecting sleeve 9 includes sleeve pipe body 10, and spacing spout 11 has been seted up to sleeve pipe body 10's surface, and the quantity of spacing spout 11 is four, and even distribution is around sleeve pipe body 10 surface.
The supporting spring 6 is arranged, so that the limiting strip 5 can be pushed to be tightly clamped in the limiting sliding groove 11, and the phenomenon that the limiting strip is loosened after being used for a long time is avoided;
through setting up the chamfer, can make things convenient for spacing strip 5 to insert inside spacing spout 11.
During the use, 1 cover nut body on the screw rod, then use spanner clockwise rotation dismouting nut 2, the inside spacing strip 5 all around of dismouting nut 2 card is in sleeve pipe body 10 surface spacing spout 11 all around, drive nut body 1 clockwise rotation and screw rod cooperation use and fasten article, after the installation, upwards stimulate nut body 4 hard, pull down nut body 4 from adapter sleeve 9, general spanner can't pull down nut body 1 from the screw rod like this, when needing to pull down nut body 1, align sleeve pipe body 10 surface spacing spout 11 all around to the bottom of spacing strip 5 all around in nut body 4, then press down hard, spacing strip 5 is drawn into spacing spout 11 and is spacing to nut body 4, then use spanner to rotate nut body 4 can, nut body 1 can not pulled down at will like this, guarantee that the article of fastening can not lose.
In summary, the following steps: this nut of theftproof is used through the cooperation of nut body 1, right-handed screw 3, nut body 4, spacing 5, supporting spring 6, fly leaf 7, cavity 8, sleeve pipe body 10 and spacing spout 11, has solved current nut and has mostly not possessed the theftproof function, and ordinary spanner just can pull down the nut, leads to easily to fasten the problem that article lost.
