Beneficial effects of the present invention：The present invention is turned on the outside of head by the way that the sleeve pipe of cylinder and block are arranged on so that
Turn head not turned so that screw rod is not easy to be disassembled, and reaches antitheft purpose；The setting of barrier rib cause sleeve pipe be not easy by
Extraction so that sleeve pipe plays due effect；Barrier rib is arranged to cylinder so that barrier rib holds when being in close contact with sleeve pipe
Easily skid so that block is not easy to be turned.
The feature and advantage of the present invention will be described in detail by embodiment combination accompanying drawing.
【Brief description of the drawings】
Fig. 1 is a kind of front view of anti-theft screw not easy to remove of the present invention.
In figure：It is recessed that 1- shafts, 2- turn head, 3- sleeve pipes, 4- blocks, 21- slots, 22- barrier ribs, 30- external screw threads, 31-
Groove, 32- block bar, 40- internal threads, 41- cover plates, 42- connecting tubes.
【Embodiment】
Refering to Fig. 1, a kind of anti-theft screw not easy to remove of the present invention, including shaft 1, turn first 2, sleeve pipe 3, block 4, resistance
Blend stop 22, the top of the shaft 1, which is fixed with, turns first 2, turns and sleeve 3 is cased with outside first 2, turn have in first 2 side wall it is some
Slot 21, barrier rib 22 is inserted with slot 21, the length of barrier rib 22 is more than the depth of slot 21, and the outer wall of described sleeve pipe 3 is provided with
External screw thread 30, the side of sleeve pipe 3 are provided with groove 31, are inserted with groove 31 and block bar 32, and the block 4 is screwed on sleeve pipe 3, block 4
It is made up of cover plate 41 and connecting tube 42, cover plate 41 is fixed on the top of connecting tube 42, has on the inwall of connecting tube 42 and external screw thread 30
The internal thread 40 being engaged, described to turn first 2 cross section be regular hexagon or square, and the internal diameter of sleeve pipe 3, which is more than, turns first 2 laterally
The circumscribed circle diameter in section, described sleeve pipe 3 are a hollow pipe, and the hollow space of sleeve pipe 3 is cylinder, and sleeve pipe 3 is positioned at stop
The lower section of bar 22, the slot 21 and barrier rib 22 are in cylinder, and lubricating oil, barrier rib 22 and slot 21 are scribbled in slot 21
Between coordinate for gap, the length of barrier rib 22 is more than the inwall of connecting tube 42 and turns the width in the gap between first 2 side wall,
The groove 31 only has one end open, and the openend of groove 31 is located at the outside of sleeve pipe 3, what the groove 31 was laterally set for one
Column hole, it is interference fits to block bar 32 with groove 31, blocks the depth that the length of bar 32 is equal to groove 31, and the block 4 is
One hollow cylinder, the height of connecting tube 42 is more than the height for turning first 2.
The course of work of the present invention：
Shaft 1 is screwed in need by a kind of anti-theft screw not easy to remove of the present invention in the course of the work, by turning first 2
On the part to be fixed, then sleeve pipe 3 is enclosed on and turned on first 2, originally will hindered without bar 32 is blocked in the groove 31 of sleeve pipe 3
Blend stop 22 is inserted in slot 21, and the longer strip barred body that one is easy to fracture is inserted in groove 31, holds strip barred body
One end, block 4 is screwed on sleeve pipe 3, then strip barred body fractureed, formed in groove 31 and block bar 32, at this time reversely
Block 4 can not be entered and be separated with sleeve pipe 3 so that block 4 rotates together with sleeve pipe 3 by turning block 4, if stirring block 4 upwards, by
In the presence for having barrier rib 22, block 4 and sleeve pipe 3 can not be extracted, if the top of sleeve pipe 3 is withstood into barrier rib 22 turns lid by force again
Cap 4, because barrier rib 22 in cylinder and slot 21 in lubricating oil is scribbled, barrier rib 22 easily rotates, sleeve pipe 3 and barrier rib 22
Between easily skid, block 4 still can not separate with sleeve pipe 3 so that turn first 2 and be not easy to be turned, reach antitheft purpose.
Above-described embodiment is the description of the invention, is not limitation of the invention, it is any to simple transformation of the present invention after
Scheme belong to protection scope of the present invention.
