Description

Swivel joint

Technical field

The utility model relates to a kind of swivel joint, relates in particular to a kind of portable DVD player, VCD, notebook computer or clamshell handset etc. of being used in and has swivel joint on the open-close type display device.

Background technique

The equipment of the open-close type display screen of Shi Yonging in the market, as portable DVD player, VCD, notebook computer or clamshell handset etc., its display screen majority can only rotate around single shaft makes flip action, and promptly configuration aspects only is provided with the rotating shaft of a direction.Therefore, the display screen of above-mentioned various device can only be opened above keyboard in pitching.180 degree rotations about its display screen can not carry out, when people are restricted at the visual angle when observing display screen, the display screen of LCD especially, its angle is very big to the influence of observing, and easily produces error, can influence people's using effect.

The Chinese patent patent No. is 2003200117419.2 " hinge-lid type rotating machinery ", it provides a kind of rotating machinery of renovating, after using this mechanism, during equipment that people state in the use, can face upward display screen to bow and rotate freely in the 180 degree horizontal extents about carrying out with the need after opening, its technological scheme that adopts is installed a horizontal rotating shaft (being the rotating shaft of Y direction) for to fixedly install a connecting plate in original pitching rotating shaft (being the directions X rotating shaft) on connecting plate.Two parts (being keyboard and display screen) that will need after being provided with like this to rotate are fixedly mounted on respectively respectively and can reach the purpose of both direction rotation like this on two supports that these two rotating shafts are rotated.

Though this setup can make that display screen rotates around both direction, but since between horizontal rotating shaft and the support disposed thereon rotationally without any position structure, the parts that are fixedly mounted on like this on the support are not easy the location when rotated, slide easily.

Summary of the invention

The purpose of this utility model provides a kind of swivel joint, can locate fast when rotated by the parts that its swivel joint connects.

The utility model can be implemented by the following technical programs: a kind of swivel joint, comprise that first link can be arranged on middleware on described first link rotationally around X-axis, can be arranged on second link on the described middleware rotationally around Y-axis, described first link rotates to rotating shaft by X with described middleware and is connected, described middleware rotates to rotating shaft by Y with described second link and is connected, described second link is fixedly installed on described Y in rotating shaft, described Y also is fixed with location piece in rotating shaft, described location piece is between described middleware and described second link, at least have two positioning grooves on the described middleware, have at least one locating bump on the described location piece, described locating bump is positioned at described positioning groove.

Described Y goes back fixed cover and is provided with transition plate in rotating shaft, resilient pad, described transition plate, resilient pad is also between described middleware and described second link, described transition plate is adjacent to mutually with described second link, described resilient pad is clamped between described transition plate and the location piece, has the fixture block that protrudes to the cushion direction on the described transition plate, has concave surface on the described location piece, have draw-in groove and spring section on the described resilient pad to described location piece direction projection, described fixture block is positioned at described draw-in groove, the pushing against on described concave surface of described spring section.

Have two positioning grooves on the described middleware, have two locating bumps that match with it on the described location piece, described each locating bump lays respectively in the corresponding positioning groove.

Described Y is a hollow rotating shaft to rotating shaft.

Compared with the prior art the utility model has following advantage: by between the middleware and second link location piece being set, at least one projection is set on location piece, at least two grooves of now joining with projection are set on second link, so when rotated by cooperating and accurately to locate between projection and the groove, and can not produce the phenomenon that reciprocatingly slides; By between the middleware and second link, transition plate and resilient pad being set also, can make second link can reduce the wearing and tearing of the middleware and second link when rotated.
