It is very important to recycle and deal with them effectively for environment protection resources saving. In this paper, on the basis of relevant knowledge of classified recycling, we combine the situation of our surveying actually, establish electronic information platform which is suitable waste electronics. More important being, we design a recovery bins can be classified recycling battery. What’s more, according to the waste electronics recycling system, we put forward to increase the recovery rate and the better classified recycling.

Current climbing appliances are difficult to ensure the steady change from walking to climbing. Consequently, we come up with a climbing mechanical appliance, design it and analyze the appliance on rationality and feasibility. The appliance is lifted by rack and pinion mechanism. In order to ensure smooth and steady movement of the appliance, a counterweight balancing mechanism is designed to adjust the centroid according to actual situation. Through the movement principle analysis of transmission mechanism for the appliance, we build its 3D model by SolidWorks. A simulation analysis has also been provided to examine the feasibility of transmission mechanism under the help of ADAMS.

This article is aimed at a kind of rotary type desk that can move, so we designed a scissor–type lifting mechanism and use MATLAB to optimize it’s rod length so as to prove the rationality of mechanism design.
