As preferably, the radius in described smooth cylindrical hole is greater than the radius of threaded circular post holes, prevents cap on nut from gliding.
As preferably, described threaded circular post holes is identical with circular hole in cap on nut, and the screw thread on its wall is also identical, is convenient to be arranged on same bolt.
As preferably, described smooth cylindrical hole is identical with the height of the cylinder of cap lower end on nut, and the cylinder of cap lower end on nut is just connected in smooth cylindrical hole.
As preferably, the height of described neck bush is identical with the height of circular hole in cap on nut, in the circular hole that neck bush is just connected on nut inside cap.
As preferably, the cross section of described groove is wedge shape, and its radial depth reduces gradually with hand of spiral, is convenient to place ball, avoids nut loosening.
As preferably, described neck bush upper end is provided with cocked bead, prevents neck bush from gliding.
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; Because on nut, cap lower end cylindrical outer side is evenly provided with rectangular plane gap, can prevent cap on nut from skidding in nut body, use 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.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the overall structure schematic diagram of a kind of special-shaped anti-loosing and anti-assembling nut axle sleeve of the utility model.
Fig. 2 is the sectional drawing of a kind of special-shaped anti-loosing and anti-assembling nut of the utility model.
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.
The special-shaped anti-loosing and anti-assembling nut of one 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 is provided with screw thread 10; On described nut in cap 2 mother rib lateral rotundum 9 wall screw thread 10 on be evenly provided with groove 11 vertically; Ball 12 is provided with in described groove 11; 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; Described neck bush 3 cylindrical wall is provided with the through hole 13 corresponding with groove 11.
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 9 in cap on nut 2, and the screw thread 10 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.
The cross section of described groove 11 is wedge shape, and its radial depth reduces gradually with screw thread 10 direction, is convenient to place ball 12, avoids nut loosening.
