The technological scheme of
the utility model is achieved in that a kind of locking and anti-cutting ferrule screwed assembly of killing of the utility model comprises screw bolt and nut, and nut is nested in the cutting ferrule; On bolt, be provided with bar portion, in the bar portion of bolt, be with the anticreep packing ring, the screw thread of bolt is connected with nut; Thread surface at nut is coated with one deck admiro layer, and dip-coating has one deck curing molybdenum layer on the admiro layer.
above-mentioned bolt is made up of head, bar portion, screw thread and guide cone, is provided with cross recess on the top of head.
The nose shape of
above-mentioned bolt is the shape of semicircle head dummy, countersunk head type or coiled hair type.
are provided with Sifangtai, supporting plane and transition circle shell of column on above-mentioned nut; On the transition circle shell of column, be provided with the taper fluting; Closing in through the taper fluting is formed with the closing in section of boring post shapes, and also is formed with one section taper hole screw thread at section internal thread of the nut at place that closes up.
above-mentioned cutting ferrule comprises basal plane, on basal plane, is provided with circular hole, is not provided with block in a symmetrical end portion of basal plane, is respectively equipped with the clamping groove that has mount grooves in another symmetrical end of basal plane.
are provided with the internal thread on the screw thread that can be threaded in bolt on above-mentioned anticreep packing ring, and the diameter of the bar portion of bolt is not more than the aperture of the internal thread of anticreep packing ring.
are owing to adopted technique scheme; The utility model is pre-installed on nut in the cutting ferrule; During use cutting ferrule is installed on the connected carrying connecting plate, then with bolt pass be screwed into the anticreep packing ring behind the plate to be connected after, be screwed in the nut again; Its nut has locking functions after the fluting and the processing of closing up, the thread surface of nut has high anticorrosive and anti-function of killing after zinc-nickel alloy and the processing of dip-coating molybdenum disulfide.The function of the anticreep packing ring of the utility model is exactly after being installed in bolt on the plate to be connected, in follow-up unloading process, prevents to lose bolt because of the work carelessness waits, and brings inconvenience to maintenance.Adopt the anticreep packing ring just can address this problem quickly and easily.The bolt of the utility model mainly bear stretching resistance, when needs bear shearing resistance, only need to strengthen a bar portion diameter and surpass Major Diam and get final product.The guide cone structure that bolt adopted of the utility model mainly is for guiding bolt in follow-up installation process gets in the screw thread of nut rapidly and accurately, reduces misoperation, the efficient that improves dismounting and safeguard.The utility model is nested in nut in the cutting ferrule, and four sides and the cutting ferrule of nut Sifangtai match, and can make nut that a certain amount of free movement can be arranged in cutting ferrule and can not rotate.The supporting plane of nut contacts with the supporting plane part face of cutting ferrule; The transition circle shell of column mainly is to guarantee that taper closing in section is easy to processing and guarantees self-locking moment; Fluting on section is closed up in taper; Inwardly closing up contacts the top of groove, after bolt screws in nut, is screwed into and produces self-locking moment when section is closed up in taper.After bolt is back-outed taper closing in section; Owing to having high tenacity, nut material produces good elasticity; So self-locking moment decay very slowly, reach the repeated removal maintenance and can both satisfy the requirement of its self-locking moment, and can reach the plain nut locking performance of against shock that is beyond one's reach.The utility model set circular hole on the cutting ferrule basal plane is to let the taper of the nut section that closes up can stretch out cutting ferrule, and reduces the material of cutting ferrule and design, and is beneficial to the monitoring to the nut self-locking moment simultaneously.Four blocks that the utility model is located at cutting ferrule basal plane four ends intermittently cooperate with four sides of nut Sifangtai, make nut that certain free movement can be arranged in block and can not rotate.When the mounting groove of connected piece during, press gently that the catch at mount grooves place on the cutting ferrule is horizontal again to be pushed into work place and can cutting ferrule to be installed in the mounting groove of connected piece for open " U " shape groove; When the mounting groove of connected piece is " O " shape groove of sealing; The available dedicated pliers blocks the two little catch at cutting ferrule mount grooves place; Penetrate work from " O " shape groove of sealing, the mount grooves of cutting ferrule can be fitted tightly on the connecting plate of connected piece work place.The utility model has improved the performance of screwed assembly housing construction greatly through technique scheme, has solved dismounting and problem difficult in maintenance effectively, and has alleviated the weight of screwed assembly structure greatly.Therefore; The utility model compared with prior art; The utility model not only has can prevent effectively that fastening piece from occurring in use killing, spin, corrosion, the advantage that fractures, but also have simple in structure, cost is low, in light weight, safe and reliable, dismounting and advantage such as quick easy to maintenance.
