The invention relates to an automatic anti-glare inner rear-view mirror, comprising a support, a mirror shell, a mirror ring, a lens and a rotating plate mounted on a ball head of the support. The mirror shell is rotarably connected with the rotating plate and is provided with a driving motor and a control circuit module inside. The driving motor drives the mirror shell to overturn the mirror with a certain angle relative to the rotating plate through a transmission plate and further drives the lens to overturn through the mirror ring; the lens is an anti-glare lens and has a second surface with the luminous reflectivity of greater than or equal to 80% and a first surface with the luminous reflectivity of smaller than or equal to 70%. The first surface and the second surface form a bevel of 3.67 degrees; a first photosensor and a second photosensor are respectively arranged on the mirror ring and the mirror shell. When the light from the back of the vehicle irradiates the first photosensor, the control circuit module controls the driving motor so that the mirror on the mirror shell on the second surface as a reflective surface automatically turns to the first glass surface as the reflective surface through the transmission mechanism, therefore, the reflectivity is overturned from the one greater than or equal to 80% to the one smaller than or equal to 70%, thereby realizing the automatic anti-glare function.

The invention relates to an experiment table, in particular to a heavy load automotive rear axle wheel side comprehensive experiment table. The heavy load automotive rear axle wheel side comprehensive experiment table is composed of a foundation support, a program control cabinet, a conveying device, a workpiece turnover device, an oil mist lubricating device and a torque testing device. The conveying device is mounted at one end of the workpiece turnover device, and the torque testing device is mounted at the other end of the workpiece turnover device. The program control cabinet is arranged on one side of the workpiece turnover device. The workpiece turnover device, the torque testing device, the conveying device and the oil mist lubricating device are respectively connected with the program control cabinet through wires. The heavy load automotive rear axle wheel side comprehensive experiment table is novel and ingenious in design, experimental measuring of the rotating speed condition and the torque performance can be achieved at one time through the workpiece turnover device and the torque testing device, and the problems that due to a traditional testing method, the labor intensity of workers is large, working efficiency is low, and the requirements for lean production and ergonomics can not be met are solved. Meanwhile, the heavy load automotive rear axle wheel side comprehensive experiment table has the advantages of being capable of achieving heavy loading, convenient to maintain, short in remodeling time, low in manufacturing cost, convenient in field operation and the like.

The invention provides a method for replacing a movable pulley block in a bridge crane. According to the method, an original steel wire rope is separated from an original movable pulley block and is wound on another movable pulley block for replacement by connecting and adjusting a nylon rope between each fixed pulley and the corresponding movable pulley, so that the replacement operation of the movable pulley block in the bridge crane is completed, and by comparison of an existing movable pulley block replacement method of the bridge crane, the replacement operation time is shortened, the operation strength is greatly reduced, the workload of workers is reduced, and the operation efficiency is improved.
