13 are fixedly connected by link block 14 with the composition of rotor 15, and rotor 15 is made up of idler wheel 16 and fixed cylinder 17
Rotational structure, and rotor 15 and concave hole 18 constitute snap-in structure and are then existed by inserting a key into keyhole 13
Rotation keyhole 13 makes it through link block 14 and rotor 15 rotates a certain angle, and makes rotor 15 with aperture
It is separated on one side with limiting device, to make nut structure convenient and simple can be unlocked, while specific key unlock
A possibility that making nut structure be stolen taker disassembly reduction, the inside of nut 4 is equipped with concave hole 18, and nut 4 and concave hole
To be welded to connect between 18, the bottom of concave hole 18 is equipped with soft board 21, and the top of soft board 21 is provided with second spring 19, and the
To be fixedly connected between two springs 19 and soft board 21, the top of second spring 19 is provided with limited block 20, and limited block 20 and the
It is Nian Jie for glue between soft board 21 and concave hole 18 to be fixedly connected between two springs 19, and soft board 21 passes through second spring 19
Elastic construction is constituted with limited block 20, and the shape of limited block 20 is trapezium structure, does not install aperture by rotor 15
One side the limited block 20 of trapezoidal shape is pushed by second spring 19, tighten it in concave hole 18, to make nut 4 more
Add and easily disassemble, while also increases its anti-theft.
The working principle of the present embodiment: the anti-theft nut structure, by the way that the fixture block 10 of two sides is separated with outline border 7,
To make fixture block 10 pass through the two sides that rubber strip 9 in accepting box 8 is connected to outline border 7, then by inserting a key into keyhole 13
In, link block 14 then being made it through in rotation keyhole 13, rotor 15 rotating a certain angle, rotor 15 is not
The one side for installing aperture pushes the limited block 20 of trapezoidal shape by second spring 19, thus make nut structure can it is convenient and simple into
Row unlock, while reduction a possibility that the unlock of specific key also makes nut structure be stolen taker disassembly, while by by fixture block
10 with outline border 7 when being engaged, and fixture block 10 is pushed and the cushion 11 of semicircle shape fits closely, the be mounted on inside cushion 11
One spring 12 is fixed by elastic pressure, to keep the fixation of fixture block 10 relatively firm, is mounted on the screw thread item of 1 outer wall of main body
2, to make nut structure when being unscrewed or being installed, screw thread item 2 can play the friction for increasing nut 4 and extracting tool
Power makes its relatively simple groove 6 for easily disassembling, being mounted on nut set 5, to make nut structure in the mistake of disassembly
Journey is more convenient to be simply fixed, and when avoiding rotating nut 4,5 the phenomenon that having skidded of nut set, it is anti-that here it is this
Steal the working principle of nut structure.
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art,
It is still possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is carried out etc.
With replacement, all within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in this
Within the protection scope of invention.
