A kind of two shaft bases of television set
Technical field
The present invention relates to a kind of television set base, particularly relate to a kind of two shaft bases of television set.
Background technique
Along with increasing substantially of living standards of the people, television set, particularly liquid crystal TV set progress in people's the sphere of life as the household appliances that a kind of fuselage is thin, screen is big, radiationless, HD digital shows.Television set base the earliest adopts two orthogonal columns fixedly to form, and does not therefore have the function of rotation, and the angle of visibility of this television set also can not be adjusted naturally.Along with people's requires increasingly highly to television set, has engendered the television set that has rotatable base on the market.Yet; Although occurred the rotating base of television set miscellaneous at present on the market, its rotational structure all changes ten thousand times without leaving the original aim or stand, and is rotating shaft with a bolt that is vertical setting all promptly; Base plate does not change, and the revolving part that is used for fixing complete machine can be realized the rotation of several angle scope around this bolt.Obviously, this television set can only be in the horizontal direction rotating certain angle, and can not do any adjustment at longitudinal direction, this just big limitations the adjustment range of angle of visibility of television set.In addition, the base of the television set of existing technology mostly just is placed in the desktop that is used to place television set, and and do not adopt any fixed structure between the desktop, this is knocked over regard to the television set that causes existing technology easily because of carelessness and the drawback of pounding the people occurs.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing technology; A kind of two shaft bases of television set are provided, and are on the basis of original structure, increase a rotating shaft; And in pedestal, increase via hole; Thereby not only widened the adjustment range of television set angle of visibility, and can complete machine be fixed on the desktop, and then overcome the some deficiencys of existing in prior technology.
The technical solution adopted for the present invention to solve the technical problems is: a kind of two shaft bases of television set comprise that one is used for fixing the fixed support of complete machine; Fixed support comprises base plate, first bolt, the first anti-skidding nut and first revolving part; Base plate is and is horizontally disposed with, and first bolt is along vertically being engaged in the base plate, and is provided with between first bolt and the base plate and prevents both first limit structures in relative rotation; First revolving part be located at the top of base plate and the cooperation through the first anti-skidding nut and pivot bush unit in first bolt, so that first revolving part can be that an angle is rotated in rotating shaft with first bolt under external force; Fixed support also comprises second bolt, the second anti-skidding nut and is used for fixing second revolving part of complete machine; Second bolt is along the top that laterally is installed in first revolving part; Cooperation and the pivot bush unit of second revolving part through the second anti-skidding nut is in second bolt, so that second revolving part can be angle of relative first revolving part rotation of rotating shaft with second bolt under the effect of external force; Also be provided with one between this second revolving part and first revolving part and be used to limit second limit structure that second revolving part rotates an angular range.
This pair shaft base also comprises a pedestal, between this pedestal and the fixed support for detachably fixing; Be provided with some via holes in the pedestal, this pedestal can be fixed on the desktop with cooperating of some fastening screw trip bolts through its via hole.
