HINGE ROTATIVE ON TWO MUTUAL ORTHOGONAL AXES

Abstract

A hinge rotative on two mutual orthogonal axes, it is used in electronic equipment having a screen and a main body; the hinge has a fixing plate having thereon a rotation seat rotative on a vertical axis relatively to the fixing plate and has two connecting legs rotative on a horizontal axis. A nut above the rotation seat is used to screw lock to a rotation shaft, thereby twisting force on the rotation seat can be adjusted; and the connecting legs each has a resilient sleeve forming thereon a plane or forming on its lateral side a strip protruding inwards, by cooperation of the planes/strips with surfaces/recesses on shafts of the connecting legs extending into the resilient sleeves, better positioning effects are obtained; and a connecting area between the rotation shaft and the fixing plate is given with four protrusions, hence the hinge gets a stable structure.

Claims

1. A hinge rotative on two mutual orthogonal axes comprising: a fixing plate connecting with a main body of a set of electronic equipment;a rotation shaft assembled with and on said fixing plate, having on its upper end a threaded portion;a position limiting sheet assembled on said rotation shaft and having a stop section;a rotation seat extended therethrough by said rotation shaft, having a plurality of protrusions on a bottom of said rotation seat to contact with said stop section for limiting swiveling range of said rotation seat; said rotation seat having two resilient sleeves extending to two mutually opposite sides;spring washers provided on said rotation seat to press said rotation seat during rotating;a nut provided above said spring washers and connected with said threaded portion on said upper end of said rotation shaft;two connecting legs each having a connecting portion and a shaft, at least two surfaces being spaced 90 degrees on said shaft;said hinge is characterized in that: said resilient sleeves of said rotation seat each is provided on its top with two slits, a plane is provided on each of said resilient sleeves to make one of said two slits at its middle; when either of said surfaces spaced 90 degrees on said shaft is contacted with said plane on said resilient sleeve, holding force is increased, and hence evidently better positioning effect is obtained.

2. The hinge rotative on two mutual orthogonal axes as claimed in claim 1, wherein said threaded portion on said upper end of said rotation shaft is locked in said nut for adjusting twisting force on said rotation seat.

3. The hinge rotative on two mutual orthogonal axes as claimed in claim 1, wherein said fixing plate has a central hole which is generally round, a periphery of said central hole is cut to form four notches, this increases force bearing areas of four protrusions on a bottom of said rotation shaft.

4. The hinge rotative on two mutual orthogonal axes as claimed in claim 1, wherein a top of said position limiting sheet is formed thereon a plurality of recesses which are mated respectively with a plurality of protrusions on a bottom of said rotation seat to get a positioning effect when said rotation seat is rotated.

5. A hinge rotative on two mutual orthogonal axes comprising: a fixing plate connecting with a main body of a set of electronic equipment;a rotation shaft assembled with and on said fixing plate, having on its upper end a threaded portion;a position limiting sheet assembled on said rotation shaft and having a stop section;a rotation seat extended therethrough by said rotation shaft, having a plurality of protrusions on a bottom of said rotation seat to contact with said stop section for limiting a swiveling range of said rotation seat; said rotation seat having two resilient sleeves extending to two mutually opposite sides;spring washers provided on said rotation seat to press said rotation seat during rotating;two connecting legs each having a connecting portion and a shaft, at least two recesses being spaced 90 degrees on said shaft;said hinge is characterized in that: said resilient sleeves of said rotation seat each is provided on its lateral side with a slit, a strip protruding inwards is provided above each of said slits, by engaging of either of said recesses with one of said slits, holding force is increased, and hence evidently better positioning effect is obtained.

6. The hinge rotative on two mutual orthogonal axes as claimed in claim 5, wherein said threaded portion on said upper end of said rotation shaft is locked in said nut for adjusting twisting force on said rotation seat.

7. The hinge rotative on two mutual orthogonal axes as claimed in claim 5, wherein said fixing plate has a central hole which is generally round, a periphery of said central hole is cut to form four notches, this increases force bearing areas of four protrusions on a bottom of said rotation shaft.

8. The hinge rotative on two mutual orthogonal axes as claimed in claim 5, wherein a top of said position limiting sheet is formed thereon a plurality of recesses which are mated respectively with a plurality of protrusions on a bottom of said rotation seat to get a positioning effect when said rotation seat is rotated.
