The mounting base body is processed by the forging process of ordinary carbon structural steel material, so that the verticality between the mounting base and the mounting plate and the dimensional accuracy of the product are more guaranteed, which greatly shortens the processing time and saves economic costs. The use of brass material can prevent the rearview mirror from being stuck due to the corrosion of the rotating part during use. At the same time, the upper and lower mounting base bodies and the copper sleeve 7 respectively adopt a crimp connection structure, which can ensure the coaxiality of the mounting base body and the copper sleeve, thereby improving the service life of the entire manual rearview mirror device.

The rotating shaft is a rotating shaft made of stainless steel; it can improve the problem that the rearview mirror cannot rotate normally due to the corrosion of the upper pole and the lower pole.

The locking and positioning structure of the opening and closing of the rearview mirror is realized by the pressing force of the torsion spring, so that the stopping rod is closely attached to the stopping groove of the lower mounting base.

The mirror frame assembly adopts a stamping forming process, the upper pole is connected with the self-lubricating radial joint bearing in the copper sleeve crimped on the upper mounting base assembly through the rotating shaft, and the lower pole is connected through the self-lubricating radial joint bearing It is connected with the rotating shaft crimped in the copper sleeve of the lower mounting base assembly. This connection mode reduces the frictional force between the upper pole, the lower pole of the mirror frame assembly and the copper sleeve, making the movement of the rearview mirror more flexible and free.

The stop lever can realize the reciprocating movement of the rearview mirror, and realizes the locking and positioning of the rearview mirror after opening and closing through the pressing force of the torsion spring. Make the stop rod close to the stop groove of the lower mounting base to prevent the mirror frame assembly from shaking back and forth. The stop has the advantages of simple structure, safe and convenient operation, and is suitable for rolling stock.

The utility model has the advantages of long observation distance, flexible and free action, convenient operation and high reliability, and can be applied to high-speed and high-power locomotives under various environmental conditions.
