Embodiment
Be described in detail of the present utility model below in conjunction with accompanying drawing.
As shown in figures 1 and 3, supporting structure of the present utility model, comprises supporting frame 4, bracket 2 and self-locking nut 1.
Supporting frame 4 is in tabular, and platelike profile can be multiple applicable shape, offers the receiving hole 43 run through above.Further, supporting frame 4 comprises supporting frame body 41, supporting frame body 41 offers the first mounting hole, supporting frame 4 is connected by the mounting edge of the first mounting hole and bolt and casing or fitting seat, and in the present embodiment, the first mounting hole comprises in two (two holes see Fig. 2 middle left and right inferior horn).
The end, one end of supporting frame body 41 is bent to assembly department 42 along the direction perpendicular to supporting frame body 41, and above-mentioned receiving hole 43 is positioned on assembly department 42.In addition, assembly department 42 is also provided with the second mounting hole, is specially two, be symmetrically distributed in receiving hole 43 both sides.
Bracket 2 is fixedly installed on a side of the supporting frame 4 at receiving hole 43 place, particularly, bracket 2 also offers two through holes matched with the second mounting hole of assembly department 42, be symmetricly set on the two ends not being provided with spacing flange of bracket 2, and be connected with two the second mounting holes by rivet 3.Further, corresponding with receiving hole 43 on bracket 2 position offers the through hole identical with receiving hole 43 size.
Bracket 2 is provided with spacing flange along the direction away from supporting frame.Particularly, spacing flange comprises two that are oppositely arranged, by two of bracket 2 relative ends respectively along away from supporting frame 4 and direction respect to one another extend to form.Each spacing flange and bracket 2 have space, wherein, the sectional shape of the entirety that upper limit flange and bracket 2 are formed is in approximate " U " shape, the sectional shape of the entirety that lower limit flange and bracket 2 are formed is in approximate " U " shape, and the distance between two spacing flange is not less than the diameter of through hole on bracket 2.Further, self-locking nut 1 is slidably arranged in the space of upper and lower spacing flange formation.It should be noted that, spacing flange, except said structure, can also be other multiple applicable shapes.
Self-locking nut 1 offers the through hole identical with receiving hole 43 size along on the direction perpendicular to supporting frame 4 place plane.Through hole, bracket 2 through hole of above-mentioned self-locking nut 1 are corresponding with receiving hole 43.In addition, self-locking nut 1 has at certain displacement amount in its bracket 2, has certain displacement compensation capability.
