Detailed Description
The present invention will be further described with reference to the accompanying drawings. The utility model provides a prevent maloperation knob switch, its includes switch body 1 and operating knob, and operating knob connects the hole suit on switch body 1's bull stick 2 through the butt joint at its back, its characterized in that: the operation knob include face guard 3 and base 4, 3 axial slidingtype suits of face guard are on base 4, be provided with aggregate unit on the base 4, aggregate unit and face guard 3 and locking pole 5 linkage, locking pole 5 passes base 4 and inserts in setting up locating hole 6 on switch body 1, restriction operation knob's rotation inwards presses face guard 3, can rotate the operation knob after forcing locking pole 5 and locating hole 6 to separate through 3 drive aggregate unit of face guard.
The excircle of the base 4 is provided with a limit groove 41, and the guide table 31 positioned on the inner hole of the face mask 3 is axially buckled on the limit groove 41.
The base 4 is provided with a spring hole 42, a supporting spring 43 is arranged in the spring hole 42, two ends of the supporting spring 43 are pressed against the base 4 and the face mask 3, and a fixing screw 44 penetrates through the spring hole 42 and is in threaded connection with the face mask 3.
Linkage be for articulating rocker 7 on base 4, locking pole 5 is connected to rocker one end, the other end supports to press in face guard 3, is provided with reset spring 8 between rocker 7 and base 4, reset spring 8 promotes one side that rocker 7 connects locking pole 5 and swings to switch body 1 direction beat all the time.
