Embodiment
As shown in Figures 1 to 9, Elevator landing limiting photoelectric switch, comprises shell 1, circuit board 2, bonnet 3, cable 6, potentiometer knob 8, receives form 10, transmitting form 11, model label 12, also comprises rubber blanket 4, locknut 5, O type circle 7, indicator light window 9.
Potentiometer knob hole 1-1 on shell 1 is stepped hole, is provided with one section of protruding 1-2 and plays position-limiting action in the 1-1 mouth of potentiometer knob hole.Potentiometer knob 8 main bodys are a plurality of revolving bodies, between the first revolving body and the 3rd revolving body, be O type ring recess 8-1, between the 3rd revolving body and the 5th revolving body, be draw-in groove 8-2, a seamed edge of the 3rd revolving body is chamfering 8-6, the 5th revolution dignity is taper seat 8-7, on the face of cylinder of the first revolving body, be provided with a fan-shaped protruding 8-3, at the end face of the first revolving body, be provided with flat recess 8-4, on the end face of the 6th revolving body, be provided with cross column 8-5.
Shell 1, circuit board 2, bonnet 3 are U-shaped structure, and shell 1 is welded together by ultrasonic welding machine with bonnet 3, and circuit board 2 is arranged between shell 1 and bonnet 3.Receive logical light form 10, the logical light form 11 of transmitting and shell 1 structure that is formed in one, reach sealing effectiveness, receive on symmetrical two inwalls that are separately positioned on shell 1 openend of form 10, transmitting form 11.Potentiometer knob 8 puts O type circle 7 and is arranged in the potentiometer knob hole 1-1 on shell 1 panel, by draw-in groove 8-2 and shell 1, be connected together, reach sealing effectiveness, the cross column 8-5 of potentiometer knob 8 and the knob sleeve of the potentiometer 2-1 on circuit board 2 are connected together, protruding 1-2 in the 1-1 of potentiometer knob hole and the fan-shaped protruding 8-3 of potentiometer knob 8 rotate and play position-limiting action potentiometer knob 8, make potentiometer knob 8 can only do forward in the 1-1 of potentiometer knob hole, reverse 240 ° of rotations, the knob of the corresponding potentiometer 2-1 being connected with potentiometer knob 8 is also forward, reverse 240 ° of rotations.
