M288070 八、新型說明： 【新型所屬之技術領域】 本創作係關於一種螢幕支撐架結構，尤指用以裝設螢 幕，並使該螢幕可相對應於其底座做任意空間位置調整之 支撐架結構者。 【先前技術】 按，隨著現在科技的進步及技術的精進，以往昂貴的 液晶螢幕漸漸為大眾購買所使用，而一般的液晶螢幕除了 配備有底座可以置放在桌面上使用以外，由於液晶螢幕其 重量輕巧及體積輕薄，故往往會利用支撐架做為支撐工具。 傳統的支撐架如我國專利申請案號第〇九〇二一四二 六0號，一種「顯示器之支撐臂構造」之專利案，其主要 由一底座、頂座、懸臂、連桿及一彈簧等元件所構成。頂 座提供於液晶顯示器固定組設。藉由一第一軸心組設於底 座之兩側壁上，使懸臂下端與底座以第一軸心形成一可轉 動之關節；懸臂上端亦藉由一第二軸心而與頂座組設，同 樣可以第二軸心形成一可轉動之關節；另在懸臂兩側上端 設有相對應的槽孔，並由一第三軸心穿置於頂座兩側壁 上。連桿之兩側壁下端設有相對應之軸孔，可藉由一第四 軸心組設於底座之兩側壁上，而令連桿下端與底座以第四 軸心形成一可轉動之關節，另在連桿的下端兩側側壁各設 有相對應的槽孔，則可供第一軸心所穿越；連桿兩側壁上 端亦藉由第三軸心軸設於頂座兩側壁上，一捲繞式彈簧套 M288070 設於第一轴心上，以令連桿具有一適當的向上作用力。底 座兩側壁設有一止擋桿。由此使得當連桿不動作時，連桿 會受液晶顯示器之重量而呈下垂狀態，同時由於此時連桿 之軸孔圓心至圓弧邊的距離大於第四軸心圓心至圓弧邊之 距離，故連桿兩側壁下端後緣所設之圓弧邊將會與止擂桿 產生卡抵作用，而令懸臂得到一支撐力，進而可用以支撐 裝設於頂座之銜接座上的液晶顯不ι§。 惟，由於傳統的支撐架僅考慮到加強懸臂之支撐力， • 藉以防止所設液晶螢幕或懸臂不會因過重下移而失去支撐 力，但隨著市面上液晶顯示器的尺寸愈來愈大，且其重量 亦將愈來愈重，傳統的支撐架當使用者欲調整所設液晶顯 示器或其他固定物之空間位置時，尤其係將懸臂由下方往 上方抬舉時，往往會因為所設之液晶顯示器或其他固定物 重量過重，而使懸臂必須施以較大力量方可抬舉起來；反 之，當使用者欲將懸臂由上方往下方移動時，則又會受到 _ 止擋桿或彈簧之卡掣，而需以較大的施力方可操作。 . 【新型内容】 .

New description: [New technical field] This creation is about a screen support structure, especially a support frame structure for installing a screen and making the screen suitable for any spatial position adjustment of the base. By. [Prior Art] Press, with the advancement of technology and the advancement of technology, the expensive LCD screens have been gradually used for mass purchases, and the general LCD screens can be placed on the desktop in addition to the base, due to the LCD screen. The weight is light and the volume is thin, so the support frame is often used as a supporting tool. A conventional support frame, such as the patent application No. 〇 〇 一 一 一 二 二 , , , , , , , , , 「 「 「 「 「 「 「 「 「 「 「 「 「 「 「 「 「 「 「 「 「 「 显示器 显示器 显示器 显示器 显示器 显示器And other components. The top seat is provided in a fixed set of liquid crystal displays. The first axial center is disposed on the two side walls of the base, so that the lower end of the cantilever and the base form a rotatable joint with the first axis; the upper end of the cantilever is also assembled with the top seat by a second axis. Similarly, the second axis can form a rotatable joint; the upper ends of the cantilever are provided with corresponding slots, and are placed on the two side walls of the top seat by a third axis. The lower end of the two side walls of the connecting rod are provided with corresponding shaft holes, which can be arranged on the two side walls of the base by a fourth axial center, so that the lower end of the connecting rod and the base form a rotatable joint with the fourth axial center. In addition, corresponding holes are provided on the side walls of the lower end of the connecting rod for the first axial center to pass through; the upper ends of the two side walls of the connecting rod are also disposed on the two side walls of the top seat by the third axial shaft, The wrap-around spring sleeve M288070 is disposed on the first axis to provide the link with an appropriate upward force. A stop lever is provided on both side walls of the base. Therefore, when the connecting rod does not operate, the connecting rod is drooped by the weight of the liquid crystal display, and at the same time, since the distance from the center of the shaft hole of the connecting rod to the side of the circular arc is greater than the center of the fourth axis to the side of the arc Distance, so the arc edge provided at the lower end of the lower end of the two side walls of the connecting rod will be in abutting relationship with the stopping rod, and the cantilever can obtain a supporting force, which can be used to support the liquid crystal mounted on the connecting seat of the top seat. Not obvious. However, since the conventional support frame only considers the support force of the cantilever, it is prevented that the liquid crystal screen or the cantilever is not lost due to excessive weight movement, but as the size of the liquid crystal display on the market becomes larger, And the weight will be heavier and heavier. When the user wants to adjust the spatial position of the liquid crystal display or other fixtures, especially when the cantilever is lifted from below, it is often because of the liquid crystal. The display or other fixtures are too heavy, so that the cantilever must be applied with a large force to lift it; otherwise, when the user wants to move the cantilever from the top to the bottom, it will be subjected to a _ stop lever or spring jam. It needs to be operated with a larger force. [New content] The main purpose of the present invention is to provide a screen support structure, which allows the user to perform the labor-saving force when moving the upward or downward movement of the fixed position of the fixed object on the support frame. operating.
