Description

The dual free dimension rotary hinge

Technical field

The utility model relates to a kind of hinge, specifically, be a kind of can be around the dual free dimension rotary hinges of two uneven axle rotations, especially can be around the dual free dimension rotary hinge of perpendicular axle rotation.

Technical background

Existing hinge, the general single-degree-of-freedom hinge that just is rotated around an axle.This single-degree-of-freedom hinge can not satisfy market demand.With flat panel TVs such as liquid crystal, plasmas, because the reason at visual angle, when watching, need a proper viewing angle, so people need carry out multi-angle, multi-faceted adjustment to flat panel TV.If the hinge that is installed on the flat panel TV is a single-degree-of-freedom, then people just can not arbitraryly adjust.If there is the hinge of dual free dimension rotation to be installed on the flat panel TV, problem just is readily solved.But the hinge that does not also occur the dual free dimension rotation in the market.

Summary of the invention

What the utility model solved is exactly the problem that existing hinge can not carry out the dual free dimension rotation, and a kind of simple in structure, reliable operation, the adjustable dual free dimension rotary hinge of moment of torsion are provided.

Dual free dimension rotary hinge described in the utility model comprises supporting plate 1,2, and it also comprises a transition frame 3 into a bent shape, and supporting plate 1,2 is rotationally connected with two folded plates 31 of

transition frame

3,32 one-tenth respectively.Like this, supporting plate 1 can rotate with respect to transition frame 3, and transition frame 3 can be rotated with respect to supporting plate 2, has promptly realized the dual free dimension rotation of supporting plate 1 with respect to supporting plate 2.

Above-mentioned dual free dimension rotary hinge, supporting plate 1 can be to be rotationally connected for 5 one-tenth by bolt 4, nut with linkage structure between the folded plate 31; Supporting plate 1 can rotate around bolt 4 axis mutually with folded plate 31.On bolt 4, overlap loading nut 5, pad 7, compression spring 6, pad 8 successively.Three pads are also arranged between supporting plate 1 and folded plate 31, and one of centre in these three pads is a flat gasket 9, and two pads of both sides are the anti-rotation pad 11 that has anti-transfer ear 10, and anti-transfer ear 10 extend in the hole on supporting plate 1 or the folded plate 31.By screwing or unscrew the nut 5 on the bolt 4, change the elastic force of compression spring 6, adjust the torque between supporting plate 1 and the folded plate 31.Why using flat gasket 9 and anti-rotation pad 11, is because will be by relatively rotating direct the contact and direct friction that replaces between supporting plate 1 and the folded plate 31 between the pad that hardness is big, wear resistance is better, frictional force is less, with low cost.

For above-mentioned arbitrary dual free dimension rotary hinge, supporting plate 2 is identical with the rotation connection structure between supporting plate 1 and the folded plate 31 with rotation connection structure between the folded plate 32.

In order to make above-mentioned dual free dimension rotary hinge can carry bigger weight, structure is more reliable and more stable, transition frame 3 also comprise one with the folded plate 31 perpendicular folded plates 33 that are connected and parallel with folded plate 32; Transition frame 3 whole one-tenth " U " shapes; Folded plate 33 is rotationally connected for 12 one-tenth with a supporting plate parallel with supporting plate 2, and this rotation connection structure is identical with rotation connection structure between supporting plate 2 and the folded plate 32; Supporting plate 12, supporting plate 2 all are connected on the dunnage perpendicular with it 13.Dunnage 13 is connected with transition frame 3 by supporting plate 12, supporting plate 2 two boards, can carry the object of bigger quality on the dunnage 13, and as LCD TVs, and supporting plate 1 can directly be fixed on the base, can realize the multi-angle adjustment of LCD TVs.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is an A-A amplification view among Fig. 1;

Fig. 3 is the stereogram of transition frame 3 among Fig. 1;

Fig. 4 be supporting plate 12 among Fig. 1, supporting plate 2 be connected with dunnage 13 stereogram.

Embodiment

Below in conjunction with embodiment and accompanying drawing thereof the utility model is described further.

Dual free dimension rotary hinge shown in Fig. 1-4 comprises supporting plate 1,2, transition frame 3 etc.Transition frame 3 is made up of three folded

plates

31,32,33, the whole one-tenth of transition frame (3) " U " shape; Folded

plate

32,33 symmetries are connected the two ends of folded plate 31, and folded

plate

32,33 is perpendicular to folded plate 31.

Supporting plate 2,12 parallels, and is rotationally connected with the folded plate 32 that parallels, 33 one-tenth respectively, and their linkage structure and rotation connection structures between supporting plate 1 and the folded plate 31 between separately are basic identical.Be that example is done an explanation with the linkage structure between supporting plate 1 and the folded plate 31 now, referring to Fig. 2, have the hole in the center portion of supporting plate 1 and folded plate 31, bolt 4 couples together supporting plate 1 and folded plate 31 by described hole and through nut 5, pad etc.Supporting plate 1 can rotate around bolt 4 axis mutually with folded plate 31.On bolt 4, overlap loading nut 5, pad 7, compression spring 6, pad 8 successively.Three pads are also arranged between supporting plate 1 and folded plate 31, and one of centre in these three pads is a flat gasket 9, and two pads of both sides are the anti-rotation pad 11 that has anti-transfer ear 10, and anti-transfer ear 10 extend in the hole 14 on supporting plate 1 or the folded plate 31.Main by by screwing or unscrew the elastic force of the nut 5 change compression springs 6 on the bolt 4, adjust the torque between supporting plate 1 and the folded plate 31.

Supporting plate 12, supporting plate 2 all are connected on the bigger dunnage of the area perpendicular with it 13, and the dunnage 13 that area is bigger can connect volume, component that quality is bigger, as plasm TV.Supporting plate 1 can directly be fixed on other base.

Like this, the axis that supporting plate 12, supporting plate 2 and dunnage 13 can be wound perpendicular to folded plate 32 rotates with respect to folded plate 32, the axis that folded

plate

31,32 can wind again perpendicular to folded plate 31 rotates with respect to supporting plate 1, has promptly realized the dual free dimension rotation of supporting plate 1 with respect to supporting plate 2.
