Lifting rotary supporting bracket for displayer

Abstract

The invention discloses a lifting rotary supporting bracket for a displayer. The supporting bracket comprises a base, and also comprises a nut piece, a screw piece, a bracket piece, a lifting piece and a rotation stopping unit, wherein the nut piece and the screw piece are mutually screwed; the both ends of the screw piece are respectively supported at the upper part and the lower part of the bracket piece in a pivot manner; the lifting piece slides up and down in the bracket piece, and is fixedly connected with the nut piece, and the lifting piece lifts relative to the bracket piece when the screw piece rotates; the rotation stopping unit comprises a blocking finger which is pivoted on the bracket piece, a positioning rod is fixed at the lower side of the blocking finger, the base adopts the structure that the upper layer and the lower layer are connected in a pivot manner, the blocking finger is fixed on the upper layer along with the bracket piece and can rotate along with the upper layer, a plurality of positioning holes are formed in the lower layer of the base, the positioning holes are uniformly distributed along the periphery, a through hole is formed in the upper layer of the base, and the positioning rod penetrates through the through hole of the upper layer of the base to be inserted into the positioning hole to fix the rotation stopping unit when the screw piece is in contact or clamped by the blocking finger. The supporting bracket can be used for conveniently adjusting the height of the displayer and synchronously adjusting the left and right viewing angles, the structure is steady after being adjusted, the supporting bracket is especially suitable for hanging overweight screens and various displayers with different weights, and the universality is higher.

Description

technical field [0001] The invention relates to a lifting and rotating support frame for a display, which belongs to the field of support frame design for a display (hereinafter referred to as display screen or screen). Background technique [0002] With the vigorous development of digital audio-visual technology, the use of monitors is extremely extensive. However, most of the displays need to be installed on a support frame for ease of use. However, the lift-type support frames of the prior art are generally not suitable for lifting and supporting super-heavy screens or display screens with different screen weights. screen, once its internal lifting spring breaks suddenly, the overweight large display screen will fall at high speed and receive a huge impact, which is very likely to cause damage to the expensive large display screen or even cause personal injury; Display screens with different screen weight specifications cannot be supported by one support frame, but each ...

However, most of the displays need to be installed on a support frame for ease of use. However, the lift-type support frames of the prior art are generally not suitable for lifting and supporting super-heavy screens or display screens with different screen weights. screen, once its internal lifting spring breaks suddenly, the overweight large display screen will fall at high speed and receive a huge impact, which is very likely to cause damage to the expensive large display screen or even cause personal injury; Display screens with different screen weight specifications cannot be supported by one support frame, but each type is required to be equipped with lifting support frames of different specifications, that is, it is necessary to develop corresponding same number of different supports according to different screen weight specifications. The lifting support frame of the power specification will increase a lot of design and development and production costs, and bring a certain amount of waste
