Height-adaptive intermediate pulley assembly and push-pull device
The invention belongs to the technical field of push-pull control, and discloses a height self-adaptive middle pulley assembly and a push-pull device.The height self-adaptive middle pulley assembly comprises a support used for supporting a push-pull body, a pulley assembly, a connecting rod assembly and an elastic piece, the length direction of the support serves as the first direction, and the width direction of the support serves as the second direction; a first rotating shaft and a second rotating shaft parallel to each other are arranged on the support in the first direction in a spaced mode. The first rotating shaft is slidably connected to the support in the first direction. The pulley assembly is provided with a third rotating shaft in the second direction. The connecting rod assembly connects the first rotating shaft, the second rotating shaft and the third rotating shaft. The elastic piece is arranged on the support in the first direction, and the free end of the elastic piece is connected with the first rotating shaft. Self-adaptive supporting height adjustment can be conducted on the pulley assembly through the elastic force of the elastic piece, so that it is guaranteed that the bearing load of the middle pulley assembly is adjustable, and the problem that the middle pulley assembly is prone to overload damage is solved.
本发明属于推拉控制技术领域，公开了一种高度自适应的中间滑轮组件和推拉装置，高度自适应的中间滑轮组件包括用于支撑推拉本体的支架、滑轮组件、连杆组件和弹性件，以支架的长度方向为第一方向，宽度方向为第二方向，支架上沿第一方向间隔设置有相互平行的第一转轴和第二转轴，第一转轴沿第一方向滑动连接于支架上；滑轮组件沿第二方向设有第三转轴；连杆组件连接第一转轴、第二转轴和第三转轴；弹性件沿第一方向设置在支架上，弹性件的自由端连接第一转轴。本发明依靠弹性件弹力使得滑轮组件能够进行自适应支撑高度调整，从而保证中间滑轮组件的承重载荷可调，避免了中间滑轮组件易过载损坏的问题。
