Specific embodiment
To make the technical problems to be solved in the utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And specific embodiment is described in detail.In the following description, there is provided the specific detail of such as specific configuration and component is only
Only to assist in comprehensive understanding embodiment of the present utility model.Therefore, it will be apparent to those skilled in the art that can be to here
The embodiment of description is made various changes and modifications without deviating from scope and spirit of the present utility model.In addition, in order to clear and
Succinctly, the description to known function and construction is eliminated.
It should be understood that " one embodiment " or " embodiment " that description is mentioned in the whole text means relevant with embodiment
Special characteristic, structure or characteristic are included at least one embodiment of the present utility model.Therefore, go out everywhere in entire disclosure
Existing " in one embodiment " or " in one embodiment " not necessarily refers to identical embodiment.Additionally, these specific spies
Levy, structure or characteristic can be combined in any suitable manner in one or more embodiments.
Referring to Fig. 1 to Fig. 5, this utility model embodiment provides a kind of combination nut, including：
Hexagon nut with flange 1；
The boss 2 being connected with described first end, the boss 2 is provided with mounting groove 21, the mounting groove 21 away from
One lateral edges of the hexagon nut with flange 1 are provided with teeth groove 22, wherein, the boss 2 with diameter greater than the hexagonal method
The nominal diameter of blue face nut 1；
Tapered packing ring 3, the packing ring 3 is connected with the interference of the mounting groove 21.
The combination nut of this utility model embodiment is mainly combined and formed by hexagon nut with flange 1 and packing ring 3, mainly should
For the installation of wheel.During the combination nut of manufacture this utility model embodiment, make with boss 2 first by cold headers upsetting
Hexagon nut with flange 1, is proof strength, it is necessary to assure the long enough of boss 2, while also functioning to positioning action herein.Need note
Meaning is, it is illustrated that the only structural representation of this utility model embodiment, the length of boss 2 can carry out according to actual needs more
Change.
Packing ring 3 and the interference fit of hexagon nut with flange 1, outer power is assembled to packing ring 3 in mounting groove 21, is installing
When, the tooth of teeth groove 22 is subject to the pressure of packing ring 3 so as to deform, and when packing ring 3 is installed in place, the tooth of teeth groove 22 points to packing ring 3
Direction, and locking effect is played, can effectively prevent packing ring 3 from deviating from, and packing ring 3 can also be rotated freely.The addition of packing ring 3, increases
The big contact area of fitting surface, improves the bearing capacity of the flange face of hexagon nut with flange 1, ensure that in structure design
