Abstract
The invention discloses a reinforced bolt and belongs to the field of fastening pieces. The reinforced bolt is composed of a screw (1), a fixing cap (2), a screwdriver opening (3) and four reinforced steel columns (4). The reinforced bolt is characterized in that each reinforced steel column (4) is made of manganese steel and the diameter of each reinforced steel column (4) is 0.1mm-2mm; the reinforced steel columns are located in the two side walls in the position from one end of the screwdriver opening (3) to the 1/2-2/3 position of the middle of the screwdriver opening (3). Due to the fact that the manganese steel is hard, when the reinforced bolt is screwed through a screwdriver, the function that the screwdriver opening (3) cannot be damaged by the screwdriver is guaranteed, and therefore a trouble, caused by damage of the screwdriver opening (3), to looseness of the bolt is avoided. The reinforced bolt is easy to manufacture, strong in operability, low in cost and obvious in effect.
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 is mainly that bolt is loosened out.But because a lot of bolts are all ironys, service time, length can make to be connected as a single entity owing to getting rusty between nut and screw rod, while loosening bolt, just need very sweat.Meanwhile, because the screw edge of a knife groove edge of irony is relatively thin, in the process of loosening, hard screw-driver usually damages screw edge of a knife groove edge, and the basis that rethinking loosens has just lost engagement, for repair work is brought great inconvenience.How to allow screw edge of a knife groove is hard becomes to prevent that screw-driver mouth groove edge from suffering damage a great problem be badly in need of solving, so utilize the harder characteristic of manganese steel, invent a kind of position of having an effect and be packed with manganese steel bar to strengthen the strengthening bolt of the anti-damage capability of screw edge of a knife groove edge be necessary after screw-driver engaging screw edge of a knife groove.
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, this strengthening bolt utilizes the harder characteristic of manganese steel, the position of having an effect after screw-driver engaging screw edge of a knife groove is packed with manganese steel bar and strengthens the anti-damage capability of screw edge of a knife groove edge, thereby reaches the object that prevents that 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, by screw rod 1, locking cap 2, the screw edge of a knife 3, strengthening steel column 4, formed, it is characterized in that strengthening steel column 4 to be that the manganese steel that is 0.1-2 millimeter by diameter is made, totally 4, to be positioned at the two side of the screw edge of a knife 3 one end and middle 1/2-2/3 distance.
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 making two parts to be fixed together.
Preferred version of the present invention is: locking cap 2 is the hemispherical dome structures that are fixed on screw rod 1 one end, the diameter of hemisphere is 0.2-10 centimetre, preparation process is with known bolt, to form with 1 cast of screw rod, fixedly time, for one end of fixing bolt, there is a screw edge of a knife 3 that is " one " font in locking cap 2 outer spherical surface central authorities, be the groove that while screwing bolt, screw-driver is meshed with it, width is 0.1-0.5 centimetre.
Beneficial effect of the present invention is, strengthening bolt utilizes the harder characteristic of manganese steel, the position of having an effect after screw-driver engaging screw edge of a knife groove is packed with manganese steel bar and strengthens the anti-damage capability of screw edge of a knife groove edge, thereby reaches the object that prevents that the screw edge of a knife groove edge from suffering damage.Strengthening bolt is made 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 is that the present invention strengthens the cross-sectional structure schematic diagram of crossing screw edge of a knife bottom surface on the locking cap of bolt.
1. screw rods in figure, 2. locking cap, 3. the screw edge of a knife, 4. strengthening steel column.
Embodiment
Embodiment one:
Strengthening bolt is comprised 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 to be that the manganese steel that is 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 guarantee that screw-driver can not damage the screw edge of a knife 3, thereby the trouble of avoiding 3 infringements of the screw edge of a knife to bring to the bolt of loosening.
More than show and described 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; that in above-described embodiment and specification, describes 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 the claimed scope of the present invention is defined by its equivalent of appending claims.
Claims (3)
1. strengthen bolt for one kind, by screw rod (1), locking cap (2), the screw edge of a knife (3), strengthening steel column (4), formed, it is characterized in that strengthening steel column (4) to be that the manganese steel that is 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.
2. strengthening bolt according to claim 1, is characterized in that 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 making two parts to be fixed together.
3. strengthening bolt according to claim 1 and 2, it is characterized in that locking cap (2) is the hemispherical dome structure that is fixed on screw rod (1) one end, the diameter of hemisphere is 0.2-10 centimetre, to form with (1) cast of screw rod, fixedly time, for one end of fixing bolt, there is a screw edge of a knife (3) that is " one " font in locking cap (2) outer spherical surface central authorities, be the groove that while screwing bolt, screw-driver is meshed with it, width is 0.1-0.5 centimetre.
