embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
A kind of nylon locking anti-loosing and anti-assembling nut as depicted in figs. 1 and 2, comprises cap 2 and neck bush 3 on nut body 1, nut; Be hexagon outside described nut body 1, inner side is cylindrical; Described nut body 1 inner top side is provided with smooth cylindrical hole 4, and lower end is provided with threaded circular post holes 5; On described nut, cap 2 lower end is cylinder 6, and upper end is provided with the chime rings 7 be fixedly connected with cylinder 6; On described nut, cap 2 is connected in smooth cylindrical hole 4 by the cylinder 6 of lower end; Outside described cylinder 6, lower end is evenly provided with rectangular plane gap 8; It described nut is the circular hole 9 of uniform radial inside cap 2; Described circular hole 9 wall upper end is embedded is provided with nylon ring 10, and lower end is provided with screw thread 11; Described nylon ring 10 is axially evenly provided with groove 12; Ball 13 is provided with in described groove 12; Described neck bush 3 is arranged in the circular hole 9 on nut inside cap 2; Be cylindrical outside described neck bush 3, sealed bottom.
The radius in described smooth cylindrical hole 4 is greater than the radius of threaded circular post holes 5, prevents cap 2 on nut from gliding.
Described threaded circular post holes 5 is identical with circular hole 6 in cap on nut 2, and the screw thread 11 on its wall is also identical, is convenient to be arranged on same bolt.
Described smooth cylindrical hole 4 is identical with the height of the cylinder 6 of cap on nut 2 lower end, and the cylinder 6 of cap 2 lower end on nut is just connected in smooth cylindrical hole 4.
The height of described neck bush 3 is identical with the height of circular hole 9 in cap on nut 2, in the circular hole 9 that neck bush 3 is just connected on nut inside cap 2.
Described groove 12 is deep on circular hole 9 wall on nut in cap 2 through nylon ring 10, and its cross section is wedge shape, and its radial depth reduces gradually with hand of spiral, is convenient to place ball 13, avoids nut loosening.
Described neck bush 3 upper end is provided with cocked bead 14, and neck bush 3 cylinder 6 wall is provided with the through hole 15 corresponding with groove 12, and cocked bead 14 prevents neck bush 3 from gliding, and ball 13 can be entered in groove 12 by through hole 15.
Use screw bolt and nut carry out fastening in, bolt through needing fastening object, cap on nut 2 is connected in the smooth cylindrical hole 4 in nut body 1 by the cylinder 6 of lower end, ball 13 is put in neck bush 3, neck bush 3 to be put on nut in cap 2, now cap on nut body 1 and nut 2 is arranged on bolt by inner screw thread 11, by constantly tightening of cap 2 on nut body 1 and nut, neck bush 3 is ejected, ball 13 falls in groove 12 by through hole 15, ball 13 is rolled to the maximum position of radial dimension along groove 12, stop subsequently, until screw, and now, nylon ring 10 can accomplish the effect of clamping bolt, prevent nuts and bolt from loosening.On counterrotating nut body 1 and nut during cap 2, ball 13 rolls to the minimum position of radial dimension, until be stuck in minimum position place, now rolls 13 pearls and bolt fits tightly, and makes bolt cannot counterrotating again.
The beneficial effects of the utility model are: owing to being provided with nut body and being connected to cap on the nut on nut body, and nut body is identical with the screw thread of cap inside on nut, now nut body and cap on nut just reach the fastening effect of two identical nuts, and saving material, reduce cost of production, install very convenient; Due to the screw thread of mother rib lateral rotundum wall in cap on nut being evenly provided with the groove that cross section is wedge shape vertically, ball is provided with in groove, the cross section of groove is wedge shape, its radial depth reduces gradually with hand of spiral, the structure of such ball engagement groove, can good stability, not easily privately dismantled by people, anti-theft feature is good; Owing to being provided with nylon ring, after on nut body and nut, cap is tightened, nylon ring can play the effect of clamping bolt, prevent nuts and bolt from loosening, and nylon ring good insulation preformance, nonmagnetic, heat insulation, lightweight, also possess high temperature resistant, high strength, decay resistance, long service life, further reduces cost of production.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
