Problems solved by technology
However, in the actual operation process, if the operator is not skilled in the operation, it is easy to be unable to accurately judge which direction the operation switch should move when returning the material.
Especially when encountering a dangerous emergency situation, it tends to become more anxious and chaotic. When you want to return the material, it will often make it work in the feeding state. If you cannot judge the action direction of the operation switch in time, it is likely to cause huge losses or cause damage. Adult Life Safety Accidents

The invention discloses a bidirectional operation remote control four-gear manual operation switch, comprising a common microswitch I, a common microswitch II and a circular driver plate, wherein the circular driver plate is connected with an intermediate shaft and provided with two circular convex plates which contact the common microswitch I and the common microswitch II at different times; and the other side of a first circular convex plate is inserted into the limiting groove of a switch locating plate. The invention solves the problems that the direction of an operation switch is single and an operator is easy to mistakenly operate in the prior art. By designing the circular convex plates and locating holes, the switch is divided into four gears, a material returning gear is added behind a feed gear; and when implementing the return of materials is needed under a critical situation, an operation handwheel is placed at a limiting position without excessively considering whether a fault operation occurs. The invention has the advantages of humanistic design, improves the safety of work, people orientation and safety first, avoids the occurrence of dangerous situation, improves work efficiency and has good application prospect and market prospect.
Description
technical field [0001] The invention relates to a manual operation switch, in particular to a two-way operation remote control four-position manual operation switch. Background technique [0002] People-oriented, safety first, now there are many machines and equipment that involve the operation of forward rotation, reverse rotation and stop rotation, especially some feeding mechanisms involving very dangerous working heads, such as some pressure machinery: Forging, forging, stamping, crushing, rolling, etc.; cutting processing machinery: feeding mechanism for slicing, crushing, etc. Sometimes these feeding mechanisms will bring some objects that should not enter the working head into the working head at the same time, especially For the operator's clothes or limbs, if there is an operation switch that can prevent the feeding mechanism from continuing to feed the operator no matter what the operation is, then the tragedy can be avoided. The surprise brought to people at this ...
