Abstract
The utility model discloses a vehicle wheel hub anti-rotation fastener comprising a bolt, a gasket, a nut and a dustproof cap. The gasket is sheathed on the bolt which is in threaded connection with a threaded hole in the center of the nut, and the dustproof cap is buckled on the nut; the bolt comprises a screw rod and a bolt head, one end of the screw rod is fixedly connected with the middle part of the bolt head, and one side of the bolt head is a stable surface matched with a wheel hub; and the circumferential surface of the fixedly-connected section of the screw rod and the bolt head is provided with longitudinal stripes surrounding the entire circumference. As the circumferential surface of the fixedly-connected section of the screw rod and the bolt head is provided with the longitudinal stripes surrounding the entire circumference, the longitudinal stripes can form friction with the wall of a fixed hole when the bolt is inserted into the fixed hole of the wheel hub, so that the bolt is difficult to be pulled out of the fixed hole of the wheel hub and the mounting is easier.
Description
Technical field
The utility model relates to a kind of fastening piece, particularly relates to the anti-firmware that screws of a kind of automobile-used wheel hub.
Background technique
The wheel hub of truck with realize being connected by bolt 1 ' and nut 2 ' (shown in Figure 1A) between the steel ring.For the convenience of installing and fastening after stability, generally all be provided with stability plane 12 ' (shown in Figure 1B) on the side of bolt 1 ' head 11 ', cylindrical bolt head 11 ' is vertically cut a part of circular arc, form parallel breach (shown in Fig. 1 C), the stabilising surface of this stability plane 12 ' and wheel hub 10 ' lean (shown in Fig. 1 D) during installation, can prevent that bolt 1 ' rotates thereupon in the process of fastening nut 2 ', fastening back is difficult for loosening, but the stability plane 12 ' of this bolt head 11 ' portion is too little with wheel hub 10 ' the contacted area, the stabilising surface of wheel hub 10 ' can cut in bolt head 11 ' portion in the process of fastening nut 2 ', thereby cause bolt 1 ' loosening rotation in wheel hub 10 ' hole, bolt 1 ' after loosening very easily is cut off under the situation of alternate load, thereby causes wheel hub 10 ' bolt short 1 ' working life, wheel hub 10 ' scrappage height.
The model utility content
The purpose of this utility model is to provide a kind of difficult drop-off, the anti-firmware that screws of tightness automobile-used wheel hub good, that be difficult for getting rusty.
For achieving the above object, technical solution of the present utility model is:
The utility model is that a kind of automobile-used wheel hub is prevented screwing firmware, and it comprises bolt, packing ring, nut, dust cap, and gasket sleeve is connected on the bolt, and bolt is screwed onto in the screw of nut central authorities, and dust cap snaps onto on the nut; Described bolt comprises screw rod and bolt head, and an end of screw rod is fixed in the middle part of bolt head, and the first side of bolt is the stabilising surface that cooperates with wheel hub; On the circumferential surface that is connected epimere of bolt screw rod and nut, offer longitudinal stripe around full week.
Described packing ring profile is a polygonal, and a port of its mesopore is outwards expansion radially, forms a hemisphere annular groove, and the other end of mesopore axially extends outward an annular flange flange along the mesopore hole wall.
Described packing ring profile is positive 12 square.
Nut central authorities have tapped hole to cooperate with the outside thread of screw rod, nut one end extends radially outward out an annular flange flange around full week, and be provided with the evagination sphere that cooperates with packing ring semi-circle annular groove on the end face of this end, this evagination sphere cooperates with packing ring semi-circle annular groove sphere.
The utility model also comprises a dust cap, and this dust cap shape and nut shape match, and snap onto on the nut, and it is made by plastic materials.
After adopting such scheme, the utlity model has following advantage:
1, because the utility model bolt offers the longitudinal stripe around full week on affixed section circumferential surface of screw rod and bolt head, when this longitudinal stripe inserts the wheel hub fixed hole at bolt, meeting and fixedly hole wall formation friction, and be not easy from the wheel hub fixed hole, to deviate from, installation is more prone to.
2, because the utility model packing ring profile is positive 12 square, and an end is along mesopore indent semi-circular groove, and the flange that the other end extends radially outward along mesopore with cooperating of nut, plays firm wheel hub, increase the load of bolt.
3, because the utility model has been set up a dust cap, this dust cap can effectively prevent the infiltration of dust, rainwater, makes that the utility model is difficult for getting rusty.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
