Description
Technical field
The utility model belongs to a kind of nut being exclusively used in freeway guardrail in technical field of fastening.
Background technique
Freeway guardrail is a kind of mutually splicing with corrugated steel guard rail plate and the continuous structure supported by principal post; when vehicle collides it; because waveform steel guard rail plate has good Impact Resisting Capability and endergonic effect; both be not easy to be smashed, can have played a very good protection to vehicle and driver and conductor again simultaneously.Along with the development of expressway, also more and more higher to the technical requirements of guardrail used, especially guardrail and its mounting such as conventional cylinder mounting is very crucial parts to the nut of connecting bolt, and it is directly linked to service property (quality) and the life-span of guardrail.In known technology, existing freeway guardrail connects fastening piece and mainly adopts tapped six squares, cylinder type nut, another shimming again during use.But limitting by its structure, structural design is unreasonable, operates complicated, connect not fastening, easily caused facility damage or stolen by artificially loosening, application life is short, changes frequent, also makes troubles to use.
Model utility content
In order to overcome the deficiencies in the prior art, solve existing freeway guardrail attaching nut structural design unreasonable, easily by the problem artificially loosened.The object of the utility model is to provide a kind of simple and practical, operates simple and easy, and the fastening locking of energy after connection, anti-loosening also antitheft, application life is long, new pattern high speed highway barrier attaching nut easy to use.
The technical scheme in the invention for solving the above technical problem is:
Freeway guardrail special with a pad conjoined lock screw, its adopt nut body bottom disjunctor be shaped with pad, and be shaped with on the pad step of nut body with institute's disjunctor with nut inner thread rotation direction identical to ratchet.
Above-mentioned freeway guardrail special with pad conjoined lock screw, described nut body is circular cone nut body, and bottom portion, the large face disjunctor of its circular cone nut body is shaped with pad.
Above-mentioned freeway guardrail special with pad conjoined lock screw, described circular cone nut body tapering is 8-12 °.
Above-mentioned freeway guardrail special with pad conjoined lock screw, ratchet on described pad step is any one uniform odd number ratchet in 9,11,13,15, the Topland of ratchet be connected in the vertical surface of nut body radial line, coast side of tooth is the plane of inclination of 15-18 °.
When the utility model uses, according to designing requirement, directly novel for basis is carried out being tightened with the one-piece type lock screw of pad, also need not another shimming, when individual event screws tightening tool and ratchet is meshing can fastening nut, and ratchet cannot drive nut body to rotate when minus thread screws direction, thus play the effect preventing from artificially loosening.
Because the utility model design have employed technique scheme, efficiently solve existing freeway guardrail attaching nut structural design unreasonable, easily by the problem artificially loosened.Also show through testing result on trial for several times, it compared with prior art, have simple and practical, economize raw material and be easy to again manufacture, operate simple and easy, the fastening locking of energy after connection, anti-loosening also antitheft, the advantages such as application life is long, easy to use, be applicable to various freeway guardrail, can also be used for electric power tower and other do not need dismantle mechanical equipment configuration etc.
