Description
Technical field
The present invention relates to Display support technical fields, more particularly, to a kind of display bracket.
Background technique
Currently, various displays are widely used in life now, wherein display is substantially with liquid crystal display
Mainstream, liquid crystal display are a kind of display of approximate plate, itself can not voluntarily stand, it is necessary to support by support frame etc.
The support of device could use, and to be more convenient to use in actual use, big multi-display also needs to go up and down.
Portioned product realizes the height adjustment of display using rotation bracket now, when rotation bracket is lifted or fallen, leads to
Double leval jib or gear drive are crossed, realizes the translation of display and nonrotational, is i.e. holding display pitching visual angle, and four connect
Structure is complicated for bar or gear drive, so that support frame especially rotation holder part is thick big, is unable to satisfy the modern times
The aesthetic needs of people.
Summary of the invention
The purpose of the present invention is to provide a kind of display brackets, are passed with solving double leval jib in the prior art or gear
Thick and heavy technical problem existing for the support frame of dynamic formula.
In order to solve the above technical problems, a kind of display bracket provided by the invention, comprising: pedestal, passes rotation bracket
Motivation structure and screen attachment base；
The rotation bracket pitch angle is adjustably pivotally connected on the base, the swing shaft between rotation bracket and pedestal
Line is the first pivot joint axis；The screen attachment base is articulated on the rotation bracket, and the screen attachment base is used to connect display,
Shielding the pivot joint axis between attachment base and rotation bracket is the second pivot joint axis；
The first pivot joint axis is arranged in parallel with the second pivot joint axis；
