Specific embodiment
In order to which the technical means, creative features, achievable purpose and effectiveness to the utility model are easy to understand, tie below
Conjunction is specifically illustrating, and the utility model is further described.
As shown in Figs 1-4, a kind of Novel hub unit high-intensitive knurled nut, including bolt body, bolt body packet
Include bolt head 1, shank of bolt 2, interconnecting piece 3, knurled portions 4 and reinforcement part 5, the both ends of interconnecting piece 3 respectively with one end of bolt head 1 and
One end of knurled portions 4 is fixedly linked, and the both ends of reinforcement part 5 are fixedly linked with the other end of interconnecting piece 3 and shank of bolt 2 respectively, even
Rotation is socketed with inverted conical shape casing 6 in socket part 3, and the inside of inverted conical shape casing 6 is equipped with ratchet 7,7 company of being fixedly attached to of ratchet
In socket part 3, the position-limit mechanism for limiting the rotation of ratchet 7 is offered on inverted conical shape casing 6.
Each ratchet on ratchet 7 includes the first vertical end and the first arc end, and one end of the first vertical end and first
One end of arc end is fixedly linked, and position-limit mechanism includes spring groove 8, spring 9 and limited block 10, the both ends of spring 9 respectively with bullet
