Abstract

A flat television wall hanging frame comprises a bottom plate fixed with a wall body and a link plate connected with the back of a monitor. The bottom plate is connected with the link pate by a regulating mechanism which comprises a height adjustment device and an oscillation angle adjustment device. The height adjustment device comprises a position block, a leader, a screw mandrel, an elevator, a screw mandrel sleeve, a retainer ring, a motor and a control circuit board which can control the motor to positively and negatively rotate. The oscillation angle adjustment device comprises a guide bar, a linkage gear, a swing pinion and a guide ball block. The flat television wall hanging frame has the following advantages that the axial direction of the screw mandrel is controlled for rotating in clockwise and counterclockwise way by controlling the positive and negative rotation of the motor, and then the screw mandrel is driven to move up and down, thus realizing the up and down moving of the link plate; as the linkage gear connected with the elevator is fixedly connected with a guide ball block, one end of which is embedded in a wave guide groove so that the guide ball block and the linkage gear sway left and right in the up and down moving process, thus realizing the left and right sway of the link plate.
