Structure-improved turning head for flat-panel television rack

Abstract

The invention discloses a structure-improved turning head for a flat-panel television rack. The structure-improved turning head comprises a connecting plate, connecting slide blocks, supporting and jacking devices and vertical columns, wherein the connecting plate is of a U-shaped structure, two sidewalls of the U-shaped structure of the connecting plate are in hinged connection with the vertical columns, a pair of longitudinal-extending long-strip holes are formed in the two sidewalls of the connecting plate, the connecting slide blocks can slide along the length direction of the long-strip holes and are axially stopped / located between the two sidewalls of the connecting plate, the axial length of the supporting and jacking devices can be stretched, the two ends of each supporting and jacking device in the length direction are respectively connected with the circumferential outer sidewall of the corresponding connecting slide block and the circumferential outer sidewall of the corresponding vertical column, and hinge axes of the vertical columns and the connecting plate do not intersect with axes of the supporting and jacking devices along the stretching direction. According to the structure-improved turning head, the adjustment is convenient, timesaving and laborsaving, a pitching angle cannot be automatically changed due to the own weight of a television after the adjustment is completed, and the angle adjustment is stable.

Description

technical field [0001] The invention relates to a flat-panel TV stand, in particular to a structure-improved swivel head of the flat-panel TV stand. Background technique [0002] The main adjustment function of the vertical TV stand is to adjust the angle by turning the head, especially the adjustment of the pitch angle. At present, the adjustment of the pitch angle is mainly through the hinged connection of two U-shaped connecting plates, and an arc is set on one of the connecting plates. A round hole is set on the other connecting plate, and the round hole and the arc-shaped hole are connected by bolts. When adjusting the pitch angle, loosen the bolts to adjust, and lock the bolts after the adjustment is completed. Through the friction between the side walls of the two connecting plates However, due to the heavy weight of the TV, under its own gravity, after a period of time, the pitch angle of the TV will automatically increase, which is not suitable for viewing and needs...

Through the friction between the side walls of the two connecting plates However, due to the heavy weight of the TV, under its own gravity, after a period of time, the pitch angle of the TV will automatically increase, which is not suitable for viewing and needs to be readjusted, and this adjustment structure needs to be adjusted on both sides. It is very laborious to adjust the bolts, which is inconvenient to use
