Abstract
The invention discloses a kind of strengthening bolt, belong to fastener areas, be made up of screw rod (1), locking cap (2), the screw edge of a knife (3), strengthening steel column (4), it is characterized in that strengthening steel column (4) is that the manganese steel being 0.1-2 millimeter by diameter is made, totally 4, be positioned at the two side of the screw edge of a knife (3) one end and middle 1/2-2/3 distance, because manganese steel is harder, therefore during with screw-driver turn strengthening bolt, can ensure that screw-driver can not damage the screw edge of a knife (3), thus avoid the screw edge of a knife (3) to damage the trouble brought to bolt of loosening.Strengthening bolt makes simple, workable, with low cost, successful.
Description
Technical field
The present invention relates to a kind of strengthening bolt, belong to fastener areas.
Background technique
In the repair procedures of everyday tools, usually can encounter the problem of some component of machine of dismounting.The dismounting of component of machine, mainly loosens out bolt.But because a lot of bolt is all irony, service time, length can make to be connected as a single entity owing to getting rusty between nut and screw rod, loosen bolt time just need very sweat.Meanwhile, because the screw edge of a knife groove edge of irony is relatively thin, in the process of loosening, screw edge of a knife groove edge usually damages by hard screw-driver, and rethinking loosens just loses the basis of engagement, for repair work brings great inconvenience.How to allow screw edge of a knife groove hard to prevent from screw-driver mouth groove edge from suffering damage becoming a great problem being badly in need of solving, so the characteristic utilizing manganese steel harder, inventing a kind of position had an effect after screw-driver engaging screw edge of a knife groove, to be packed with manganese steel bar to strengthen the strengthening bolt of screw edge of a knife groove edge resistant to damage ability be necessary.
Summary of the invention
In order to overcome the easy impaired difficult problem of screw edge of a knife groove edge of conventional bolt, the invention provides a kind of strengthening bolt, the characteristic that this strengthening bolt utilizes manganese steel harder, the position had an effect after screw-driver engaging screw edge of a knife groove is packed with manganese steel bar to strengthen screw edge of a knife groove edge resistant to damage ability, thus reaches the object preventing the screw edge of a knife groove edge from suffering damage.
The technical solution adopted for the present invention to solve the technical problems is:
Strengthening bolt, be made up of screw rod 1, locking cap 2, the screw edge of a knife 3, strengthening steel column 4, it is characterized in that strengthening steel column 4 is that the manganese steel being 0.1-2 millimeter by diameter is made, totally 4, strengthening steel column is positioned at two side, and is distributed in the 1/2-2/3 from neutral position to screw edge of a knife two ends symmetrically.
Preferred version of the present invention is: screw rod 1 is cylindrical metal bar, and diameter is 0.1-5 centimetre, and length is 1-100 centimetre, is threaded above, with the threaded engagement in nut bore, is used for two parts are fixed together.
Preferred version of the present invention is: locking cap 2 is the hemispherical dome structures being fixed on screw rod 1 one end, the diameter of hemisphere is 0.2-10 centimetre, preparation process is with known bolt, form with screw rod 1 one pieces of cast, when fixing, for one end of fixing bolt, there are the screw edge of a knife 3 in " one " font in locking cap 2 outer spherical surface central authorities, the groove that when being screwing bolts, screw-driver is meshed with it, width is 0.1-0.5 centimetre.
Beneficial effect of the present invention is, the characteristic that strengthening bolt utilizes manganese steel harder, the position had an effect after screw-driver engaging screw edge of a knife groove is packed with manganese steel bar to strengthen screw edge of a knife groove edge resistant to damage ability, thus reaches the object preventing the screw edge of a knife groove edge from suffering damage.Strengthening bolt makes simple, workable, with low cost, successful.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is the overall structure schematic diagram that the present invention strengthens bolt.
Fig. 2 be the present invention strengthen bolt locking cap on cross the cross-sectional structure schematic diagram of screw edge of a knife bottom surface.
1. screw rods, 2. locking cap in figure, 3. the screw edge of a knife, 4. strengthen steel column.
Embodiment
Embodiment one:
Strengthening bolt is made up of screw rod 1, locking cap 2, the screw edge of a knife 3, strengthening steel column 4, it is characterized in that strengthening steel column 4 is that the manganese steel being 0.1-2 millimeter by diameter is made, totally 4, strengthening steel column is positioned at two side, and be distributed in screw edge of a knife two ends and middle 1/2-2/3 place symmetrically, because manganese steel is comparatively hard, therefore during with screw-driver turn strengthening bolt, can ensure that screw-driver can not damage the screw edge of a knife 3, thus avoid the screw edge of a knife 3 to damage the trouble brought to bolt of loosening.
Screw rod 1 is cylindrical metal bar, and diameter is 0.1-5 centimetre, and length is 1-100 centimetre, is threaded above, can, with the threaded engagement in nut bore, be used for two parts are fixed together.
Locking cap 2 is the hemispherical dome structures being fixed on screw rod 1 one end, and the diameter of hemisphere is 0.2-10 centimetre, and preparation process, with known bolt, is form, when fixing, for one end of fixing bolt with screw rod 1 one pieces of cast.There are the screw edge of a knife 3 in " one " font in locking cap 2 outer spherical surface central authorities, and when being screwing bolts, the groove that screw-driver is meshed with it, width is 0.1-0.5 centimetre.
More than show and describe basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should be appreciated that; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications; these changes and improvements all fall in the claimed scope of the invention, and application claims protection domain is defined by its equivalent of appending claims.
