the parts in the drawings are numbered as follows: 1. the nut comprises a nut body, 2, a threaded hole, 3, a conical closing-in body, 11, a reinforcing sleeve, 12, a lock washer, 13, a first support ring, 14, a second support ring, 15, a first conical body, 16 and a second conical body.

Detailed Description

The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the utility model easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the utility model.

Referring to fig. 1-3, the present embodiment includes:

the utility model provides a full tooth reinforcement hub nut, includes nut body 1 and runs through the screw hole 2 that sets up at the inside central point of nut body and put, screw thread on the inner wall of screw hole 2 adopts full tooth thread structure, nut body 1 includes reinforcement sleeve 11, lock washer 12, first support ring 13, second support ring 14, first cone 15 and second cone 16, lock washer 12 and first support ring 13 set up the upper and lower both ends at reinforcement sleeve 11 respectively, first cone 15 is connected between reinforcement sleeve 11 and first support ring 13, second cone 16 passes through second support ring 14 and sets up the upper end at first support ring 13.

Further, the cross section of the first taper 15 is an inverted trapezoid structure, and the cross section of the second taper 16 is a trapezoid structure. Two opposite conical table structures are formed by the first support ring 13, the second support ring 14, the first conical body 15 and the second conical body 16, so that certain force is consumed when the force is applied, the bearing of the force is reduced, and the strength is further ensured.

The upper end and the lower end of the nut body 1 are both provided with conical closing-in bodies 3, the upper end and the lower end of the threaded hole 2 are respectively communicated with the conical closing-in bodies 3, and the top pressure points and the bottom closing-in effect of the hub nut are formed by the conical closing-in bodies 3.

The cross section of the reinforcing sleeve 11 is of a hexagonal structure, so that the connection strength of the hub nut is reinforced, and the structure is firm. Meanwhile, the outer diameter of the first support ring 13 is greater than that of the second support ring 14, specifically: the outer diameter of the lower port of the second cone 16 is equal to the outer diameter of the second support ring 14; the outer diameter of the lower end of the first cone 15 is equal to the outer diameter of the first support ring 13, and the outer diameter of the upper end of the first cone 15 is equal to the outer diameter of the second support ring 14.
