Beneficial effects of the present invention: the present invention by cylindrical sleeve pipe and block are arranged on and turn outside head,
Make to turn head cannot be turned so that screw rod is difficult to be disassembled, and reaches antitheft purpose；Setting of barrier rib
Put so that sleeve pipe be difficult to by extract so that sleeve pipe play due effect；Barrier rib is set to cylinder to be made
Obtain when barrier rib is in close contact with sleeve pipe and easily skid so that block is difficult to be turned.
Inventive feature and advantage will combine accompanying drawing by embodiment and be described in detail.
[accompanying drawing explanation]
Fig. 1 is the front view of the present invention the most easily detachable a kind of anti-theft screw.
In figure: 1-shaft, 2-turn outside head, 3-sleeve pipe, 4-block, 21-slot, 22-barrier rib, 30-
Screw thread, 31-groove, 32-block bar, 40-female thread, 41-cover plate, 42-connecting tube.
[detailed description of the invention]
Refering to Fig. 1, the most easily detachable anti-theft screw of one of the present invention, including shaft 1, turn 2, sleeve pipe
3, block 4, barrier rib 22, described shaft 1 top is fixed with and turns 2, turns 2 and outside is cased with one
Sleeve pipe 3, turns and has some slots 21 on 2 sidewall, be inserted with barrier rib 22, barrier rib 22 in slot 21
Length is more than the degree of depth of slot 21, and described sleeve pipe 3 outer wall is provided with external screw thread 30, and sleeve pipe 3 side is provided with recessed
Groove 31, is inserted with blocking bar 32 in groove 31, described block 4 is screwed on sleeve pipe 3, and block 4 is by cover plate 41
Forming with connecting tube 42, cover plate 41 is fixed on the top of connecting tube 42, connecting tube 42 inwall has with outward
The female thread 40 that screw thread 30 matches, described in turn 2 cross section be regular hexagon or square, sleeve pipe 3
Internal diameter is more than turning a circumscribed circle diameter for 2 lateral cross section, and described sleeve pipe 3 is the pipe of a hollow, sleeve pipe 3
Hollow space is cylindrical, and sleeve pipe 3 is positioned at the lower section of barrier rib 22, and described slot 21 and barrier rib 22 are equal
In cylinder, in slot 21, scribble lubricating oil, be matched in clearance between barrier rib 22 and slot 21, described
Barrier rib 22 length is more than connecting tube 42 inwall and the width in gap that turns between 2 sidewall, described recessed
Groove 31 only has one end open, and the opening of groove 31 is positioned at the outside of sleeve pipe 3, and described groove 31 is a horizontal stroke
To the column hole arranged, blocking bar 32 and groove 31 are interference fits, and blocking bar 32 length is equal to groove
