Description

A kind of emergency stop switch

Technical field

The utility model relates to electric switch, relates in particular to a kind of emergency stop switch with operating state deixis.

Background technology

Existing emergency stop switch is through increasing the function that outside direction board comes the indication of realization state, having brought many inconvenience to installation mostly.In addition, existing emergency stop switch is to rely on the lower surface of traveller to contact with the contact, and is less with contact push rod contact-making surface, causes the contact stabilization of contact relatively poor.Emergency stop switch tightly stop epicranium when touching also be easy to generate misoperation.

Summary of the invention

The utility model technical problem to be solved is to provide a kind of emergency stop switch with operating state deixis.

The utility model further technical problem to be solved is to provide a kind of and has the state deixis, can effectively prevent to bump the emergency stop switch that produces misoperation because of tightly stopping the epicranium mistake.

The technical scheme that the utility model adopted is: a kind of emergency stop switch comprises and tightly stops head, shell, traveller, swivel nut and press head back-moving spring; Tightly stop head and comprise pressure cap and to the connecting portion that extends below, the upper end of this connecting portion links to each other with pressure cap; Traveller wears in the enclosure; The top of this traveller offers a chamber, and the connecting portion that tightly stops head stretches in this chamber, and passes the diapire of chamber with one and the threaded connector of said swivel nut is threaded; Swivel nut is between the chamber bottom of the bottom surface of said connecting portion and traveller; The press head back-moving spring is set on the said swivel nut, is characterized in, this emergency stop switch also comprises state indicating ring and state indicating ring back-moving spring; The upper surface of state indicating ring is provided with cue mark, and the periphery of state indicating ring is provided with a pair of to the leg that extends below; The surface of pressure cap is provided with watch window; The top side wall of shell is provided with a pair of groove, and the bottom surface of this a pair of groove is a helicoid, and a pair of leg of state indicating ring is separately positioned in this a pair of groove, and is resisted against on the helicoid of groove; State indicating ring back-moving spring is between state indicating ring and shell.

The utlity model has following advantage:

1, cooperating of the helicoid of the utility model a pair of leg of adopting the state indicating ring and shell can cooperate the internal state indicating ring tightly to stop to move up and down and left rotation and right rotation, reaches deixis exactly;

2, have the gap between the chamber bottom of the bottom surface of swivel nut and traveller, this gap has constituted the pretravel of tightly stopping head; Because the existence in this gap,, can not trigger the traveller action at once, thereby can prevent misoperation effectively when tightly stopping the epicranium mistake when bumping;

3, the lower end of traveller is provided with the pressing plate that has a pair of wing plate portion, has increased the contact area with the contact greatly, has stopped the unsteadiness of contact contact.
