It sets and utilizes the bolt resisted inside screw-in lower shell to piece to prevent bolt from being screwed out to piece, play the function of anti-loose anti-theft.
To achieve the above object, the present invention proposes a kind of antitheft claw type nut, including chassis, locking tooth and cylinder,
The cylinder includes lower shell and upper shell, runs through in the lower shell and upper shell and is equipped with first through hole, the lower shell
The inner wall of partial first through hole is equipped with internal thread, and the center on the chassis is equipped with the second through-hole of corresponding first through hole, described
Cylinder is fixed on the center of chassis face, and the locking tooth is fastened around the edge of chassis face.
Preferably, being additionally provided with several third through-holes on the chassis, the quantity of the third through-hole is at least one.
Preferably, the top surface on the chassis is equipped with coarse lines.
Preferably, the quantity of the locking tooth is at least 2, the side in the separate axle center of the locking tooth is equipped with first
Fin is equipped with the second fin on first fin, and the outermost of first fin is no more than the outermost on chassis, described
The outermost of second fin is no more than the outermost of the first fin.
Preferably, one or more fin can also be arranged in addition to first fin and the second fin.
Preferably, the upper shell is equipped with several straight slots, the quantity of the straight slot is 4 to 10.
Preferably, bottom opening 1/4 to 1/3 place of second through-hole apart from chassis is surrounded with to piece, it is described
One end to piece is fixed on the inner wall of the second through-hole, described to be gradually reduced to width of the piece from side wall to axle center, described to support piece
It can overturn to open or be tightly attached on inner wall along inner wall.
Beneficial effects of the present invention:The present invention is made by the way that several locking teeth and rough surface with fin are arranged on chassis
The nut being tapped into plank is firmly embedded in plank and cannot rotate, dual solid by screwing in tapping screw in third through-hole
Determine nut, assists upper shell to be bloomed by corn nail bit to which the another side in plank is triple by the way that straight slot is arranged on upper shell 32
Plank is fixed, utilizes the bolt resisted inside screw-in lower shell to piece to prevent to piece by being arranged inside the second through-hole of bottom plate
Bolt is screwed out, and the function of anti-loose anti-theft is played.
The feature and advantage of the present invention will be described in detail by embodiment combination attached drawing.
