Embodiment
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figures 1 to 4, a kind of foot switch, it comprises base plate 1, cover plate 2, connecting plate 3, upper cover 4, guide fixed block 5, press head 6.
Guide fixed block 5 is arranged on the middle part of base plate 1, and the lower end of best guide fixed block 5 is fixedly connected with base plate 1 by screw.The middle part of guide fixed block 5 is provided with movable chamber 5.1, is provided with the guide vane end stop 7 moving up and down distance for limiting press head 6 in movable chamber 5.1, and guide vane end stop 7 can be up and down in movable chamber 5.1; The lower end of press head 6 extend in movable chamber 5.1 from the upper end of guide fixed block 5, and is fixedly connected with guide vane end stop 7.
Cover plate 2 is the upper and lower loop configuration run through, and base plate 1 is arranged on the lower end of cover plate 2, breathes out base plate 1 most and uses screw to be fixedly connected with between cover plate 2.The lower end of upper cover 4 extend in cover plate 2, and is flexibly connected with cover plate 2 by connecting plate 3; Conflict with the lower surface of upper cover 4 and be connected in the upper end of press head 6.Particularly, the lower end of connecting plate 3 is provided with the second boss 3.1 extended to cover plate 2, and the upper end of cover plate 2 is provided with the flange 2.1 preventing the second boss 3.1 from shifting out from the upper port of cover plate 2, so just achieves being flexibly connected of upper cover 4 and cover plate 2.Be bolted to connection between best connecting plate 3 and upper cover 4.The strong point between second boss 3.1 and flange 2.1 and the strong point between upper cover 4 and press head 6, any one direction of upper surface that can be implemented in upper cover 4 carries out trampling control, press head 6 all can be subject to downward power and promote contact 9.1(as shown in Figure 6), the break-make realizing foot switch controls, and sensitivity can not decline.
Foot switch also comprises the elastomeric element 8 for press head 6 being pressed to upper cover 4; Elastomeric element 8 be arranged between base plate 1 and guide vane end stop 7 or be enclosed within guide fixed block 5 outer, be placed between press head 6 and guide fixed block 5.
Foot switch also comprises sensitive switch 9, and sensitive switch 9 is arranged on base plate 1, and near guide fixed block 5 place; The upper end of press head 6 is provided with the first boss 6.1 extended to sensitive switch 9, and the contact 9.1 of sensitive switch 9 arranges the below of the first boss 6.1.Best sensitive switch 9 is fixedly connected with base plate 1 by switch fixing casing 11.In use press down contact 9.1 by the first boss 6.1 of press head 6, as shown in Figure 6, realize the operating state of sensitive switch 9.
The present invention can also do following optimization:
Further: elastomeric element 8 can be return spring; Return spring is enclosed within the upper end of guide fixed block 5, conflicts with the lower surface of press head 6 and be connected in the upper end of return spring, conflicts with the lower end of guide fixed block 5 and be connected in the lower end of return spring.Return spring can play good reset response, and when being carried in the downforce on upper cover 4 and disappearing, return spring can make press head 6 is lifted, and contact 9.1 resets, and returns to position as shown in Figure 5.
The lower end of best guide fixed block 5 and/or the lower surface of press head 6 are provided with the convenient annular groove embedding return spring.The present invention adopts: the lower end of guide fixed block 5 is provided with the convenient annular groove embedding return spring, and the lower surface of press head 6 is provided with the convenient annular groove embedding return spring.The annular groove at this place can play good fixation.
Further: the lower surface of upper cover 4 contacts with press head 6 and is set to sphere, and the upper surface of press head 6 is set to sphere.And sphere better can realize carrying out trampling in any one direction of upper surface of upper cover 4 control, press head 6 all can be subject to downward power and promote contact 9.1, and the break-make realizing foot switch controls, and sensitivity can not decline.
Further: in movable chamber 5.1, to be also provided with plastic sliding bearing 13, be connected by plastic sliding bearing 13 between guide vane end stop 7 with movable chamber 5.1 inwall, this effectively can reduce the frictional force between the inwall in guide vane end stop 7 and movable chamber 5.1, improves the sensitivity of product.
Further: foot switch also comprises slipmat 10, slipmat 10 is arranged on the lower surface of base plate 1.
Further: the length span of the second boss 3.1 is 1.1mm ~ 4mm.When the length of the second boss 3.1 is less than 1.1mm, the second boss 3.1 be connected not compact between flange 2.1, cause the second boss 3.1 easily to come off; When the length of the second boss 3.1 is greater than 4mm, the second boss 3.1 be connected too compact between flange 2.1, cause the sensitivity of total to decline.
Comparative test result is as follows:
The length of 3.1 0.6mm 1.1mm 1.6mm 2.1mm 2.6mm 3.1mm 3.6mm 4.1mm 4.6mm
Falling-off effect Come off Do not come off Do not come off Do not come off Do not come off Do not come off Do not come off Do not come off Do not come off
Sensitivity Checking cannot be continued Better Better Better Better Better Better Bad Stuck, cannot assemble
The present invention also announces a kind of assembly method:
Step 1: foot-operated line 12 is fixed on sensitive switch 9,
Step 2: sensitive switch 9 is fixed on and is contained on base plate 1;
Step 3: the bottom of plastic sliding bearing 13 being inserted in guide fixed block 5, is enclosed within press head 6 by return spring 8, then press head 6 is arranged on guide fixed block 5 by guide vane end stop 7, is finally fixed on base plate by guide fixed block 5;
Step 4: upper cover 4 is fixed on cover plate 2 by connecting plate 3;
Step 5: base plate 1 is fixed on cover plate 2;
Step 6: paste slipmat 10.
Further: step 1 also comprises and being fixed on switch fixing casing 11 by sensitive switch 9, is contained on base plate.
Further: step 2 also comprises and being fixed on base plate by foot-operated line with foot-operated line pressure block.
