    摘要： A wheeled-chair chassis with a suspension mechanism which comprises a chassis structure, a suspension system, a transmission system and two front and rear wheels; the chassis structure includes a steel pipe frame similar to an inverse triangular frame. The suspension system includes shock absorbers, rocker arms, and pivot pins; one end of the rocker arm is connected with a pivot base on lower end of the steel pipe frame by means of a pin, while the other end thereof is mounted with a gear rack for mounting a motor of the transmission system, a gear box, and the rear wheels. The shock absorber is fixedly mounted between the steel pipe frame and the rocker arm to provide a retractable movement for absorbing a shake from the rear wheels and the rocker arm caused by a rough road surface in order to provide the chair with a comfortable driving. Since each of the systems is an independent assembly, it is easy to assemble.

    摘要翻译： 一种具有悬挂机构的轮椅底盘，包括底盘结构，悬挂系统，传动系统和两个前轮和后轮; 底盘结构包括类似于倒三角架的钢管框架。 悬挂系统包括减震器，摇臂和枢轴销; 摇臂的一端通过销与钢管框架下端的枢轴底座连接，而另一端安装有用于安装传动系统的电机的齿条，齿轮箱， 和后轮。 减震器固定地安装在钢管框架和摇臂之间，以提供可伸缩的运动，用于吸收由路面粗糙引起的后轮和摇臂的震动，以便为椅子提供舒适的驾驶。 由于每个系统都是一个独立的组件，所以很容易组装。

    摘要： A manually adjustable apparatus for a zoom lens includes a body, a lens set, a sliding base, a rack sliding base, and a transmission gear. The lens set is installed at the body. There is an outer gear located at the rear end of the lens cone of the lens set. The sliding base is fastened at the body. On the bottom surface of the rack sliding base, there is a rack. The transmission gear is pivoted on the body and is interlocked with the rack and the outer gear. The present invention turns the rack sliding base manually to make the lens cone rotate and move via the rack, the transmission gear, and the outer gear for controlling and zooming the lens set. No power is needed so that the power loading of the still camera is reduced, and the cost of the still camera is reduced.

    摘要翻译： 用于变焦镜头的可手动调节的装置包括主体，透镜组，滑动基座，齿条滑动基座和传动齿轮。 镜头组安装在身上。 位于透镜组透镜锥后端的外齿轮。 滑动底座固定在身体上。 在机架滑动底座的底面上有一个机架。 传动齿轮在主体上枢转并与齿条和外齿轮互锁。 本发明通过手动转动机架滑动座，使透镜锥体通过齿条，传动齿轮和外齿轮旋转并移动，用于控制和变焦镜头组。 不需要电源，从而降低了静态照相机的功率负载，降低了摄像机的成本。
