Description

Technical Field

[0001] The utility model relates to the technical field of equipment switches, in particular to a switch handle. Background Art

[0002] During material production, the switching valves in the reaction system need to be operated with a wrench, but the switching valves used in some reaction systems are generally hidden inside the chassis.

[0003] For example, a load switch and operating handle with publication number CN108573821B includes a spring operating mechanism and an operating handle. The operating handle includes a handle sleeve and a handle rod passing through the handle sleeve. The handle sleeve is provided with a long hole where the handle rod passes through. When the spring of the spring operating mechanism moves past the inflection point by an angle, it will drive the main shaft and the handle sleeve to suddenly accelerate. The long hole is used to make way for the handle rod to accelerate in the opposite direction relative to the handle sleeve. Applying external force to the handle rod causes the spring to store energy. After rotating past the inflection point by a small angle, the spring will instantly reset, driving the handle sleeve to rotate faster. The handle rod rotates in the opposite direction relative to the handle sleeve within the long hole. This process avoids the potential danger to the operator caused by the handle rod's sudden acceleration with the handle sleeve, and this solution does not affect the assembly structure and assembly efficiency of the spring operating mechanism.

[0004] Based on the search of the above patents and in combination with the devices in the prior art, it was found that the length of the sleeve of the existing handle cannot be adjusted when in use. For the switch valve hidden inside the chassis, the existing handle is often unable to be used or inconvenient to operate due to limited space, and the design needs to be improved urgently to adapt to more application scenarios.
