Description
Technical field
The utility model relates to a kind of switch, particularly a kind of foot switch with safeguard protection.
Background technology
Foot switch is a kind ofly to step on or step on the switch of control circuit break-make by pin, use both hands can not and control circuit in to replace both hands to reach the purpose of operation.In medicine equipment, pressing equipment, welding equipment, Weaving device, printing machinery, be widely used.
Traditional foot switch mainly by shell, be located at the travel switch in the shell and be articulated in control pedal on the shell, wherein, travel switch is connected by lead with external circuit, be connected by driving member between control pedal and the travel switch, when control pedal was driven by external force, control pedal was implemented control by driving member to travel switch, travel switch is opened, then impel the foot switch energising, otherwise then foot switch is in off-state.
Because foot switch mostly is located on the ground, if foot switch need not to start, and stepped on by staff or other people mistake foot switch is started, make and produce or there is certain potential safety hazard in operation.
Summary of the invention
At the deficiency that prior art exists, the utility model provides a kind of a kind of foot switch with safeguard protection safe, simple in structure.
For achieving the above object; the utility model provides following technical scheme: a kind of foot switch with safeguard protection; include shell, be located at the travel switch in the shell and be articulated in control pedal on the shell; be connected by driving member between control pedal and the travel switch; it is characterized in that: described shell is provided with an end and is electrically connected with travel switch; the emergency stop switch that the other end is electrically connected with outer lead; emergency stop switch is provided with and extends to outside the shell, can impel the urgency of emergency stop switch energising and disjunction to stop control knob.
Adopt technique scheme; by the emergency stop switch that is electrically connected with external circuit shell setting; make travel switch and being connected of external circuit need to implement to be communicated with by emergency stop switch; when being subjected to suddenly to stop control knob, emergency stop switch drives; when being in off-position; control pedal is implemented to drive by driving member and travel switch and also can't be made this foot switch energising, thereby has played the effect of safeguard protection, has eliminated owing to mistake is stepped on the potential safety hazard that foot switch exists with this.
The utility model further is set to: suddenly stop control knob for can press flexible button, suddenly stop that control knob is in the shell and be provided with moving contact towards an end of emergency stop switch, the corresponding position of emergency stop switch and this moving contact is provided with to fit with this moving contact can impel the fixed contact of emergency stop switch energising, is electrically connected by lead between described emergency stop switch and the travel switch.
Adopt technique scheme, suddenly stop control knob and regulate the service position of moving contact by the retractility of himself, it is fashionable that fixed contact on moving contact and emergency stop switch touches, then emergency stop switch energising, travel switch is energising thereupon also, and just can make foot switch energising by to the trampling of control pedal this moment, arrange simple in structure, easy to operate like this.
The utility model further is set to: emergency stop switch is set up in anxious stopping between control knob and the travel switch by mounting column.
Adopt technique scheme, the installation that makes in the shell is set like this arranges more rationally, the while also can be shirtsleeve operation provides place mat.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
A kind of foot switch with safeguard protection as shown in Figure 1; include shell 1, be located at the travel switch 2 in the shell 1 and be articulated in control pedal 3 on the shell 1; be connected by driving member 4 between control pedal 3 and the travel switch 2; need to prove; driving member 4 is drive link; one end of this drive link and control pedal 3 are conflicted; the control end of the other end and travel switch 2 is implemented to conflict; and shell 1 is provided with the activity space for the drive link activity, is arranged with also on the drive link that make can automatically reset spring 5 after the drive link work.In the utility model embodiment, shell 1 is provided with an end and is electrically connected with travel switch 2, and the emergency stop switch 6 that the other end is electrically connected with outer lead, emergency stop switch 6 are provided with and extend to outside the shell 1, can impel the urgency of emergency stop switch 6 energisings and disjunction to stop control knob 7.In the such scheme; by at shell 1 emergency stop switch 6 that is electrically connected with external circuit being set; make travel switch 2 and being connected of external circuit to implement to be communicated with by emergency stop switch 6; when being subjected to the anxious control knob 7 that stops, emergency stop switch 6 drives; when being in off-position; control pedal 3 is implemented to drive by driving member 4 and travel switch 2 and also can't be made this foot switch energising, thereby has played the effect of safeguard protection, has eliminated owing to mistake is stepped on the potential safety hazard that foot switch exists with this.
In the utility model embodiment, suddenly stop control knob 7 for can press flexible button, suddenly stop that control knob 7 is in the shell 1 and be provided with moving contact 71 towards an end of emergency stop switch 6, the corresponding position of emergency stop switch 6 and this moving contact 71 is provided with to fit with this moving contact 71 can impel the fixed contact 61 of emergency stop switch 6 energisings, is electrically connected by lead 8 between emergency stop switch 6 and the travel switch 2.Suddenly stop control knob 7 and regulate the service position of moving contact 71 by the retractility of himself, it is fashionable that fixed contact 61 on moving contact 71 and emergency stop switch 6 touches, then emergency stop switch 6 energisings, travel switch 2 is energising thereupon also, this moment is by trampling control pedal 3, just can make the foot switch energising, arrange simple in structure, easy to operate like this.In order to make arranging and install more rationally in the shell 1, emergency stop switch 6 is set up in anxious stopping between control knob 7 and the travel switch 2 by mounting column 9.
