Description
The utility model relates to a kind of self-locking foot switch.
The foot switch that at present domestic and international equipment or electric equipment products are used; as shown in Figure 1, all be to tramp with one's feet down behind the pedal A, spring B is compressed; switch C is switched on; pine pin rear spring B resets, and pedal A returns, and the problem that this structure exists is not protection of switch; if household electrical appliance adopt this foot switch; a child or the pet that meeting is creeped all may unintentionally be pressed energize, makes electrical equipment running and may damage.
In view of this, the long-pending experience of being engaged in this area research work for many years of this creator through feasibility study repeatedly, gets generation of the present utility model eventually.
At the shortcoming of prior art, the purpose of this utility model is to provide a kind of self-locking foot switch; Make switch have self-locking device, to prevent the generation of accident.
For achieving the above object, the utility model is achieved through the following technical solutions: a kind of self-locking foot switch, form by elements such as switch enclosure back shroud, switch enclosure base, switch enclosure, switch, unlock button, straight pin, stop pin, locking spring and back-moving springs; It is characterized in that: switch is fixed on the switch enclosure base, and switch enclosure also is connected and fixed with the switch enclosure base, and switch enclosure back shroud and switch enclosure are connected and fixed becomes one; Unlock button is located in the switch enclosure, and straight pin is inserted in the circular hole of unlock button, and the stop pin upper end that is installed with the locking spring is located in the circular hole of switch enclosure, and its top is provided with unlock button; Lower side at the close switch enclosure base of switch enclosure is provided with back-moving spring simultaneously.
Be provided with shade at the unlock button top, the circular hole periphery of switch enclosure correspondence also is provided with a circle wall simultaneously.
On the unlock button hole wall of switch enclosure, be provided with oblong slots.
Switch enclosure, switch enclosure base and the employed material of switch enclosure back shroud are plastics.
Straight pin is a metal material.
Unlock button and stop pin are plastics or metal material.
By a kind of self-locking foot switch of the utility model, overcome the shortcoming of prior art, reached the purpose of above-mentioned creation; The utility model is under the prerequisite that keeps former foot switch function, set up a self-locking device, have only when stepping on the unlock button of self-locking device, the foot switch box just can move forward and backward, be switched on or switched off power supply, if do not step on unlock button, and the switch enclosure surface that only tramps with one's feet, because this moment, switch enclosure was lockable, can't move, so can not be by the on-off switch power supply, or only step on unlock button and the action of buck switch box before undirected, still can not be switched on or switched off power supply.
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Fig. 1 is existing foot switch structural representation;
Fig. 2 is the utility model structural representation;
Fig. 3 is that Fig. 2 A is to view.
As shown in Figures 2 and 3, a kind of self-locking foot switch of the utility model is made up of elements such as switch enclosure back shroud 1, switch enclosure base 2, switch enclosure 3, switch 4, unlock button 6, straight pin 7, stop pin 9, locking spring 10 and back-moving springs 11; Wherein, switch 4 is fixed on the switch enclosure base 2 by screw 5, and switch enclosure 3 also is connected and fixed with switch enclosure base 2, and switch enclosure back shroud 1 is connected and fixed by screw 12 with switch enclosure 3 becomes one; Unlock button 6 is located in the switch enclosure 3, and straight pin 7 is inserted in the circular hole of unlock button 6, is provided with oblong slots 8 on the unlock button hole wall of switch enclosure 3; Stop pin 9 upper ends that are installed with locking spring 10 are located in the circular hole of switch enclosure 3, and its top is provided with unlock button 6; Lower side at switch enclosure 3 close switch enclosure bases 2 is provided with back-moving spring 11 simultaneously.
In order to prevent that dust from falling in unlock button 6 holes of switch enclosure 3, be provided with shade 6a at unlock button 6 tops, the circular hole periphery of switch enclosure 3 correspondences also is provided with a circle wall 3a simultaneously.
The utility model stop pin 9 is under the elastic force effect of locking spring 10, and insert in the circular hole of switch enclosure 3 its upper end at ordinary times, and switch enclosure 3 can not be moved along plane D, and this moment, switch enclosure 3 can not touch the contact of switch 4.Foot switch can not be worked; Have only when tramping with one's feet down unlock button 6, locking spring 10 is compressed, the upper surface of stop pin 9 is depressed into the same flat with the upper surface D of switch enclosure base 2, at this moment, do not want loose pin, use buck switch box 3 before the pin, switch enclosure 3 is just along the location notch E of switch pedestal 2 (among Fig. 2 left direction) motion forward thereupon, and switch 4 promptly was switched on or disconnected this moment.Behind the pine pin, under the effect of back-moving spring 11, switch enclosure 3 is replied initial position, and this moment, stop pin 9 inserted in switch enclosure 3 circular holes once more, and switch enclosure 3 promptly is lockable.
Though if step down in switch enclosure 3 above, do not step on unlock button 6, though perhaps vertically step on unlock button 6 down, the action that then pushes away forward with pin, then switch akinesia has reached the purpose of protection.
In sum, be preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that is produced does not exceed the scope of technical solutions of the utility model, all belong to protection range of the present utility model.
