Abstract

本发明公开了一种省力升降机构,内门形架的左、右竖臂分别插装在外门形架的左、右竖臂中,内门形架的左、右竖臂上分别设置与外门形架的左、右竖臂的内壁滑动接触的滑轮机构;外门形架的横臂中装牵引带卷轮,牵引带卷轮与左、右牵引带的一端连接,左、右牵引带的另一端通过各自的托轮机构后与分别左、右竖臂的下部固定连接;通过牵引带卷轮的正转或反转,使左、右牵引带同时卷入或松开,从而带动门形架的左、右竖臂沿外门形架同时上升或下降。本发明结构合理,使用方便,省力性能好,特别适用于立式办公用电脑桌的升降机构;滑轮机构使内门形架的竖臂与外门形架的竖臂之间保持一定间隙,永远不会碰伤。

Description

一种省力升降机构
技术领域
本发明涉及一种升降机构。
背景技术
现有的立式办公用电脑桌,其升降机构有多种形式,但一般省力性能不理想,需要进一步加以改进。
发明内容
本发明的目的在于提供一种使用方便、省力性能好的省力升降机构。
本发明的技术解决方案是:
一种省力升降机构,其特征是:包括外门形架、内门形架,内门形架的左、右竖臂分别插装在外门形架的左、右竖臂中,内门形架的左、右竖臂上分别设置与外门形架的左、右竖臂的内壁滑动接触的滑轮机构;外门形架的横臂中装牵引带卷轮,牵引带卷轮与左、右牵引带的一端连接,左、右牵引带的另一端通过各自的托轮机构后与分别左、右竖臂的下部固定连接;通过牵引带卷轮的正转或反转,使左、右牵引带同时卷入或松开,从而带动门形架的左、右竖臂沿外门形架同时上升或下降。
所述滑轮机构为滑动轴承机构,使内门形架的竖臂与外门形架的竖臂之间保持一定间隙,不会碰伤。所述托轮机构包括位于外门形架的横臂与竖臂交界处的托轮及位于外门形架的横臂中的托轮。
所述托轮上方设有将牵引带压紧在托轮上的压紧轮。所述滑轮机构包括多组滑轮。
本发明结构合理,使用方便,省力性能好,特别适用于立式办公用电脑桌的升降机构。滑轮机构使内门形架的竖臂与外门形架的竖臂之间保持一定间隙,永远不会碰伤(拉伤等)。
附图说明
下面结合附图和实施例对本发明作进一步说明。
图1是本发明一个实施例的结构示意图。
具体实施方式
一种省力升降机构,包括外门形架1、内门形架2,内门形架的左、右竖臂3、4分别插装在外门形架的左、右竖臂5、6中,内门形架的左、右竖臂上分别设置与外门形架的左、右竖臂的内壁滑动接触的滑轮机构7;外门形架的横臂中装牵引带卷轮8,牵引带卷轮与左、右牵引带9、10的一端连接,左、右牵引带的另一端通过各自的托轮机构后与分别左、右竖臂的下部固定连接;通过牵引带卷轮的正转或反转,使左、右牵引带同时卷入或松开,从而带动门形架的左、右竖臂沿外门形架同时上升或下降。
所述滑轮机构为滑动轴承机构,使内门形架的竖臂与外门形架的竖臂之间保持一定间隙,不会碰伤。所述托轮机构包括位于外门形架的横臂与竖臂交界处的托轮11及位于外门形架的横臂中的托轮12。
所述托轮上方设有将牵引带压紧在托轮上的压紧轮13。所述滑轮机构包括多组滑轮。
