Description
Technical field
The present invention relates to a kind of dismountable chek bolt structure, further relate to a kind of dismountable loosing and theft preventing bolt structure body.
Background technique
As everyone knows, bolt is widely used on the various machinery by the flange connection as the basic part that connects various mechanical parts and device.According to present status in China, the antitheft whole dependence of iron tower adopt anti-theft bolt to realize, therefore all the time, all adopt the burglarproof lock jack panel.Though the burglarproof lock jack panel has solved antitheft problem,, bring very large difficulty for rebuilding construction, emergency work construction owing to can't dismantle.Especially 08 year southern large size icing falls tower, during emergency dealing, owing to can't dismantle the burglarproof lock jack panel with instrument, so must bolt could be cut off with gas cutting, the workman needs to carry equipment such as oxygen cylinder, acetylene cylinder, cutter or gas cutting machine and just can finish, and has had a strong impact on the progress of speedily carrying out rescue work.
There have been some dismountable loosing and theft preventing bolts in the prior art.A kind of loosing and theft preventing bolt (seeing this document Fig. 3 and Fig. 4) is for example disclosed among the CN2692402Y, because the shelves face 53 of the shelves face 313 of this bolt and nut all is vertically disposed, therefore very high to the requirement of using construction, carrying out with this bolt when fastening, must fix bolt head 31 or 5 one on nut, another is rotated, and could guarantee on inclined-plane 312 and shelves face 313 and the packing ring that bearing surface 43 closely contacts mutually accordingly.Otherwise inclined-plane and the discontiguous situation of bearing surface might appear in the opposing party, and can't reach locking effect this moment.From Fig. 3 and Fig. 5 also as can be seen the arris fillet on the packing ring all be straight line type, this design not only can cause the fabricating cost of packing ring to raise, and also exists surface friction drag not high enough, and may occur the situation of becoming rusty and connecing when long-term the use.The design deficiency of this bolt maximum is the breach 45 on its packing ring, though this patent claims that this design can guarantee this bolt can't be unloaded under the situation of not using special tool(s) assurance packing ring and bolt or packing ring and nut to rotate simultaneously, but actual conditions are also exactly so, as long as prop up this breach 45 with screw-driver, impact screw-driver with external force, it is slight loosening just can to allow fastening bolt produce, and just can this bolt be unloaded with common wrench then.
In addition, US5626449A also discloses a kind of similar bolt, but the angle between the shelves face on its packing ring and packing ring plane (horizontal plane) is the obtuse angle, exists and the same problem of CN2692402Y, and is very high to the requirement of using the workmen equally.Rib 52 on this packing ring is linear equally, also exists and the same problem of CN2692402Y.

Embodiment
As shown in Figure 1, bolt structure body 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 axis 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 axis 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 a and Fig. 4 b are packing rings of the prior art, and the angle α of bearing surface 43 and packing ring another side (horizontal plane) is respectively the obtuse angle, and (Fig. 4 a) and right angle (Fig. 4 b).Fig. 4 c is a packing ring of the present invention, and bearing surface 43 is 75 ° with the angle α of packing ring another side (horizontal plane).
Fig. 5 a is a packing ring of the prior art, and filler rod 44 is a straight line type.Fig. 5 b and 5c are packing rings of the present invention, and the filler rod 44 among Fig. 5 b is " S " type, and Fig. 5 c is the salient point of rule.Fig. 5 b and Fig. 5 c 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 axis 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 resistivity 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 tightness between packing ring and bolt head and packing ring and the nut, reaches better Drop-proof effect, and reduced in the construction labor claim." S " type filler rod or salient point have increased surface friction drag, have reached better Drop-proof 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, screw-driver etc. can't find point of application of force, thereby can't guarantee that packing ring and bolt or packing ring and nut rotate simultaneously, thereby reach real antitheft purpose.
If when wanting quick-release bolt 3, must be with special tool(s) clip packing ring 4, and simultaneously packing ring 4 and nut 5 or packing ring 4 and bolt head 31 are contained simultaneously and rotate, promptly under packing ring 4 and 7 motionless situations, nut 5 or bolt 3 are rotated smoothly, reach antitheft actual effect.The inner chamber of special tool(s) is a step inner chamber, the shape of the bottom step 81 of inner chamber identical with the shape of packing ring (for example oval), height is identical or more bigger than the thickness of packing ring with the thickness of packing ring, the shape of the shape of inner chamber intermediate step 82 and nut or bolt head identical (for example Hexagon), thereby can be simultaneously packing ring 4 and nut 5 or packing ring 4 and bolt head 31 be contained simultaneously, and packing ring 4 and nut 5 or packing ring 4 and bolt head 31 are rotated simultaneously by external force.
