Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
Fig. 1 is the profile of traditional scheme;
Under normal usage: tightening outer cutter net, safety pin is in pressed status, Fig. 2 is the profile of this utility model switching device (cell switch is energized, machine normal operation);
Fig. 3 is the profile of this utility model switching device (when taking off outer cutter net: when taking off outer cutter net, safety pin unclamps, on and off switch disconnects, and machine quits work).
Detailed description of the invention
Switch shrapnel structure of the present utility model, is a metallic conduction sheet, and it is respectively arranged at two ends with elastic force cantilever, and this cantilevered distal end is for being connected with circuit board contacts, to play the dual-use function of on and off switch and discharge cock.
As in figure 2 it is shown, this utility model switching device, including switch shrapnel 1, circuit board 4, switch push pedal 5, safety pin 6 and guard member 7; wherein; switch shrapnel 1 is a metallic conduction sheet, and it is respectively arranged at two ends with elastic force cantilever, and this cantilevered distal end is for contacting connection with circuit board 4 (PCB);Switch push pedal 5 be located at above switch shrapnel 1 one cantilever, for pull switch shell fragment 1 and make this cantilevered distal end contact circuit board 4, with realizes start shooting;Safety pin 6 is located at above another cantilever of switch shrapnel 1, for pull switch shell fragment 1 and make this cantilevered distal end contact circuit board 4, so that circuit is in stablizing open state;Guard member 7 is located at above safety pin 6; for applying pressure to safety pin 6; with pull switch shell fragment 1 and make its cantilevered distal end contact circuit board 4; realize stable start; when taking off guard member 7, safety pin 6 loses the pressure of pull switch shell fragment 1, and switch shrapnel 1 separates with circuit board 4; making circuit is off-state, it is achieved safeguard protection effect.
In a detailed description of the invention of the present utility model, the cantilevered distal end at switch shrapnel 1 two ends is designed as curved hook shape, is the contact point that switch shrapnel 1 carries out with circuit board 4 contacting bottom hook-type.
Switching device of the present utility model is under normal usage (when loading onto such as guard members such as outer cutter nets), safety pin 6 pull switch shell fragment 1 also makes its local (cantilever end) flexural deformation, circuit board 4 copper-foil conducting electricity is pressed and be fully contacted to the switch shrapnel of deformation 1 time thus realizing stable start (see Fig. 2), when taking off outer cutter net guard member 7, the pressure being applied to switch shrapnel 1 by safety pin 6 is undone, the natural resilience of switch shrapnel 1, realize being automatically separated between itself and circuit board 4 copper-foil conducting electricity, making circuit is off-state, thus realizing intended shutdown effect (see Fig. 3).Simultaneously, under the promotion of switch push pedal 5, this switch shrapnel 1 is close to circuit board soldering tin face and is moved reciprocatingly, the position of pass shifted onto by switch, switch shrapnel 1 contact point just disconnects with circuit board 4 copper-foil conducting electricity and realizes shutdown, the position that switch push pedal 5 is shifted onto open, switch shrapnel 1 contact point just realizes conducting with circuit board 4 copper-foil conducting electricity.Switch shrapnel 1 bending angle cleverly of the present utility model and safety pin 6 movement travel accurately ensure that the stability of safety pin and switch simultaneously.
Switching device of the present utility model, as long as a metallic conduction sheet, can realize the dual-use function of on and off switch and discharge cock.Compared with traditional structure, save two metallic conduction sheets and a wire, lacked a scolding tin station simultaneously, both reduced material cost, reduce again cost of labor and improve production efficiency.
Hair bulb clipping machine of the present utility model, including fuselage, cutter head, motor, fuselage includes above-mentioned switching device.This utility model hair bulb clipping machine, owing to only needing a metallic conduction sheet, can realize the dual-use function of on and off switch and discharge cock, and the cost of product is effectively reduced, and the competitiveness of product is also greatly reinforced.
Embodiments described above is comparatively concrete and detailed, but therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that, for the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these broadly fall into protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
