Abstract

L'invention concerne une structure de support de panneau d'affichage dans laquelle des caractéristiques de ressort d'un ressort disposé sur un bras sont des caractéristiques équilibrant parfaitement un moment de rotation par le poids d'un panneau d'affichage lorsque le moment varie en ajustement de hauteur du panneau d'affichage. Dans la structure de support d'affichage, la hauteur du panneau d'affichage peut être ajustée par une force extrêmement petite, la structure est facilement actionnable, le panneau d'affichage peut toujours rester immobile dans un état équilibré dans une plage d'ajustement de hauteur, le bras est réduit en épaisseur de telle sorte qu'elle est presque égal à l'épaisseur de l'espace pour le ressort, et l'épaisseur lorsque la structure est pliée est réduite. Dans la structure de support d'affichage, un cadre d'installation de panneau d'affichage est fixé de façon pivotante à l'extrémité avant du bras fixé de façon pivotante à une base, et le panneau d'affichage est fixé au cadre. Le bras a un mécanisme de liaison. Le cadre d'installation de panneau d'affichage est monté de façon pivotante sur un arbre de liaison du mécanisme de liaison par un mécanisme de frottement. Le mécanisme de liaison a le ressort équilibrant un moment de rotation provoqué par le poids du panneau d'affichage monté sur le cadre d'installation de panneau d'affichage.
