Abstract
The utility model discloses an improved structure of a nut, which comprises a hexangular locking head and a flange connected with the hexangular locking head. A section of annular lug is extended outwards from the center on the other side of the flange; the diameter of the excircle of the annular lug is smaller than the diameter of the flange, thereby forming the echelonment; and a screw hole of the annular lug is communicated with the flange and a screw hole of the hexangular locking head, and screws thereof are the same. The utility model adds the section of annular lug on the conventional nut, and the annular lug is arranged on the other side of the flange, therefore the screw section of the whole nut is lengthened, the screw at the flange section is not easy to wear, and the service life of the nut is prolonged.
Description
Technical field
The utility model relates to a kind of locking element, particularly relates to a kind of improvement structure of nut.
Background technique
Locking element commonly used mostly is to be made of nuts and bolt, and nut is screwed onto on the bolt.The nut of commonly using is made up of hexagonal locking head and the flange that is connected on the hexagonal locking head, and the thread and the bolt of flange inner bolt hole are spirally connected.Because flange is shorter, the internal screw thread section in it is shorter, wearing and tearing easily, and working life is short.
The model utility content
The purpose of this utility model is to provide a kind of improvement structure of nut of long service life.
For achieving the above object, technical solution of the present utility model is:
The improvement structure of a kind of nut of the utility model, it is made up of hexagonal locking head and the flange that is connected on the hexagonal locking head; Opposite side at flange extends outward one section annular flange flange from central authorities, and this annular flange flange outside diameter is littler than flange diameter, forms steppedly, and the screw of this annular flange flange communicates with the screw of flange, hexagonal locking head, has identical thread.
After adopting such scheme, because the utility model is to have increased by one section annular flange flange on the nut of commonly using, this annular flange flange is positioned at the opposite side of flange, thereby has increased the length of whole nut threaded section, make that the thread of flange section is not easy to wear, increased the working life of nut.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is an axonometric drawing of the present utility model.
Embodiment
As shown in Figure 1, the utility model is a kind of improvement structure of nut, and it is made up of hexagonal locking head 1 and the flange 2 that is connected on the hexagonal locking head 1.
From central authorities' one section annular flange flange 3 in place that stretches out, these annular flange flange 3 outside diameters are littler than flange 2 diameters at the opposite side of flange 2, form steppedly, and the screw of this annular flange flange 3 communicates with the screw of flange 2, hexagonal locking head 1, has identical thread.
Because when the utility model and bolt 10 are spirally connected, increased the thread in one section annular flange flange 3, make the length growth of nut threaded section.
Emphasis of the present utility model just is: increased by one section annular flange flange on flange.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
Claims (1)
