【Embodiment】
Refering to Fig. 1, a kind of anti-theft screw with unilateral bearing of the present invention, including shaft 1, turn first 2, first sleeve 3, the
Two sleeve pipes 6, unilateral bearing 4, connecting rod 5, there is the first external screw thread 10 on the shaft 1, the top of shaft 1, which is fixed with, turns first 2, institute
It is in regular hexagon to state and turn first 2 cross section, and turning first 2 top center has a fixing hole 21, has internal thread 20 in fixing hole 21, is twisted
It is cased with a first sleeve 3 outside dynamic first 2, in cylinder, the center of first sleeve 3 has to be engaged the first sleeve 3 with turning first 2
Vertical through hole 31, have inner ring 41 and outer ring 42 on the unilateral bearing 4, connecting rod 5 passes through inner ring 41, have in connecting rod 5 with it is interior
The second external screw thread 50 that screw thread 20 is engaged, the second external screw thread 50 are respectively positioned on the lower section of inner ring 41, and connecting rod 5 is screwed in fixing hole 21
On, groove 51 is turned in connecting rod 5, second sleeve pipe 6 is fixed on the outside of outer ring 42, and the cross section of the second sleeve pipe 6 is in centre
The regular hexagon of hole, the top center of connecting rod 5 have fixing groove 55, turn the bottom that groove 51 is located at fixing groove 55, twist
Dynamic groove 51 is in in-line or cross, has a circle neck 56 on the inwall of fixing groove 55, is protected in fixing groove 55 embedded with plastics
Lid 7, there is the card article 76 being engaged with neck 56 on plastic protection cover 7, the connecting rod 5 with inner ring 41 by being welded to connect,
By being welded to connect, the height of the inner ring 41 is more than the height of outer ring 42, the top of inner ring 41, outer ring for two sleeve pipes 6 and outer ring 42
In same level, the inscribed circle diameter of second sleeve pipe 6 is equal to the one or two lasso for 42 tops and the top of connecting rod 5
External diameter, described turn are stamped protective cover 8, first external screw thread 10 and outside first 2 and the assembly that is formed of unilateral bearing 4
The direction of rotation of two external screw threads 50 is identical, and the locked direction of unilateral bearing 4 is identical with the tightening direction of shaft 1.
The course of work of the present invention：
A kind of anti-theft screw with unilateral bearing of the present invention in the course of the work, turns the second sleeve pipe 6 and drives unilateral bearing 4
Moved to locked direction and tighten screw rod, cover protective cover after tightening, because first sleeve 3 is in cylinder, screw rod is not easy
Directly it is unscrewed, turns groove 51, it is necessary to which plastic protection cover 7 is destroyed to expose when needing to unload screw rod, then connect connecting rod 5
Logical unilateral bearing 4 unloads, and then takes out first sleeve 3, finally turns first 2 and disassemble screw rod.
