The specific embodiment
As shown in Figure 1, the loosing and theft preventing bolt structure body of extracting tool dismounting of the present invention comprises bolt 3, packing ring 4, packing ring 7 and nut 5.
Wherein: bolt 3 has bolt head 31 and bolt shaft 32,31 one-tenth hexagons of bolt head, the root edge of its each side 311 is provided with the equiangularly arranged and high low wedge shape dentation inclined-plane 312 that is inclined thrust surface on one side on one side, and each wedge shape dentation inclined-plane 312 joins continuously, make 312 the most shallow places, last wedge shape dentation inclined-plane just be next 312 bosom, wedge shape dentation inclined-plane, and each wedge shape dentation inclined-plane 312 joining place form the block face 313 with high low head; 32 of bolt shaft have screw thread 321.
5 one-tenth hexagons of nut, has wedge shape dentation inclined-plane 52 in the upper limb of its each side 51 with the relative moulding in continuous inclined-plane of packing ring 7, each wedge shape dentation inclined-plane 52 joining place forms the block face 53 of the high low head of tool equally, the central authorities of nut 5 have a screw again, can with the screw thread 321 corresponding screw locks of bolt 3.
Fig. 4 is the packing ring of the loosing and theft preventing bolt structure body of extracting tool dismounting of the present invention, and bearing surface 43 is 75 ° with the angle α of packing ring another side (horizontal plane).
Fig. 5 a and 5b are the packing rings of the loosing and theft preventing bolt structure body of extracting tool dismounting of the present invention, and the filler rod 44 among Fig. 5 a is " S " type, and Fig. 5 b is the salient point of rule.Fig. 5 a and Fig. 5 b are semi-major axis and the not too big ellipse of semi-minor axis difference.
According to above-mentioned member when being implemented, in the filler rod 44 of packing ring 4 mode, the bolt shaft 32 of bolt 3 is passed packing ring 4 and workpiece 6 in regular turn towards workpiece 6, pass a packing ring that is inverted 4 again, and screw togather locking, so that two workpiece 6 are locked together admittedly with nut 5 and bolt 3; Therebetween, the block face 313,53 of bolt head 31 or nut 5 is pushed the bearing surface 43 of packing ring 4, and to drive packing ring 4 rotations, packing ring 4 is along the inclined-plane 442 of filler rod 44, so can screw tight bolt 3 and workpiece 6 easily gradually, and make the arris fillet 44 of packing ring 4 embed workpiece 6 surfaces because of pressurized; If bolt head 31 or nut 5 will oppositely be done, because the wedge shape dentation inclined- plane 312,52 of bolt 3 and nut 5 compresses mutually with the inclined-plane 42 of two packing rings 4 respectively and contends with, add the resistance of 6 of the facade 441 of filler rod 44 and workpiece, make bolt 3 have the effect that is difficult for getting loose.Because angle α is an acute angle, can increase the interlock compactness between packing ring and bolt head and packing ring and the nut, reaches better slip-off preventing effect, and reduced in the construction labor claim." S " type filler rod or salient point have increased frictional resistance, have reached better slip-off preventing effect, the situation that the rust that may occur when having reduced long-term the use simultaneously connects.The most important thing is that because packing ring do not have breach, screwdriver etc. can't find the point of application, thereby can't guarantee that packing ring and bolt or packing ring and nut rotate simultaneously, thereby reach real antitheft purpose.
Extracting tool of the present invention comprises a cylindrical dismounting body 8, from its bottom one inner chamber that is used for the suit bolt structure body is arranged upwards, and this inner chamber is a step inner chamber.Inner chamber bottom (with the bolt structure body contact that will the contact) shape of part 81 is identical with the shape of packing ring, all be oval, height is identical with the thickness of packing ring, or it is more bigger than the thickness of packing ring, the shape on step inner chamber part 81 tops 82 is identical with the shape of nut or bolt head, all be hexagon, the shape of step inner chamber topmost 83 is square, and it is used for inserting the square body plug of engineering turning handle commonly used.
Under packing ring 4 and 7 motionless situations, nut 5 or bolt 3 are rotated smoothly, thus can not quick-release bolt 3 or nut 5.If when wanting quick-release bolt 3, at first the square body plug of turning handle is inserted the projected square part 83 of instrument step inner chamber of the present invention from dismounting body 8 tops, step inner chamber with instrument of the present invention is sleeved on the structure then, make step inner chamber part 81 block packing ring, step inner chamber part 82 is blocked nut or bolt head, rotate specific purpose tool with turning handle, thereby drive packing ring and nut or packing ring and bolt head rotate together, thereby bolt is unloaded.
