The purpose of this utility model is to provide a kind of speed-regulating switch, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of speed-regulating switch, comprise connecting rod, governor housing, speed regulator speed limit knob, magnet steel elevating bracket, magnet steel and magnetic induction sensor, one end of described shift knob is movably connected on handle by pin shaft structure, arrange connecting rod bottom the other end of shift knob, one end of connecting rod connects the magnet steel elevating bracket of governor housing inside; Described magnet steel elevating bracket is slidably connected on the chute of governor housing inside, the inside of magnet steel elevating bracket arranges magnet steel, the below of magnet steel elevating bracket is provided with magnetic induction sensor, magnetic induction sensor is fixedly installed on the inside of magnet steel elevating bracket, and the top of described governor housing arranges speed regulator speed limit knob.
As further program of the utility model: magnetic induction sensor is Hall element.
As further program of the utility model: the top of magnet steel elevating bracket arranges magnet steel back-moving spring.
As further program of the utility model: the switch ejector pin contact bottom described shift knob connects the switch triggering button of main power switch, and main power switch is fixedly arranged on handle inner, arranges push-button reset spring between shift knob and main power switch.
As further program of the utility model: main power switch is sensitive switch.
As further program of the utility model: the handle housing of described shift knob side arranges switch lock set button.
Compared with prior art, the beneficial effects of the utility model are: this practicality increases the magnetic-inductive device of magnetic induction sensor and magnet steel formation on the basis of common speed regulator, before shift knob arrives extreme limit of travel, carried out the rotating speed of control machine at any time by the travel position of magnetic-inductive device inductive switch button, the slow acceleration and function of stepless speed regulation that can control are pointed in realization.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of magnetic-inductive device.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 2, in the utility model embodiment, a kind of speed-regulating switch, comprise main power switch 1, switch push rod 2, push-button reset spring 3, shift knob 4, connecting rod 5, governor housing 6, speed regulator speed limit knob 7, magnet steel back-moving spring 8, magnet steel elevating bracket 9, magnet steel 10, magnetic induction sensor 11, switch lock set button 12 and switch triggering button 13, one end of described shift knob 4 is movably connected on handle by pin shaft structure, connecting rod 5 is set bottom the other end of shift knob 4, one end of connecting rod 5 connects the magnet steel elevating bracket 9 of governor housing 6 inside.
Described magnet steel elevating bracket 9 is slidably connected on the chute of governor housing 6 inside, the inside of magnet steel elevating bracket 9 arranges magnet steel 10, the below of magnet steel elevating bracket 9 is provided with magnetic induction sensor 11, magnetic induction sensor 11 is fixedly installed on the inside of magnet steel elevating bracket 9, magnetic induction sensor 11 is Hall element, the top of magnet steel elevating bracket 9 arranges magnet steel back-moving spring 8, and the top of described governor housing 6 arranges speed regulator speed limit knob 7.
Switch push rod 2 bottom described shift knob 4 contacts the switch triggering button 13 connecting main power switch 1, main power switch 1 is fixedly arranged on handle inner, main power switch 1 is sensitive switch, slight strength touch switch trigger button 13, switch open function can be realized, push-button reset spring 3 is set between shift knob 4 and main power switch 1.
The handle housing of described shift knob 4 side arranges switch lock set button 12, by switch lock set button 12 floatless switch button 4 according to pressing depth.
This practicality increases the magnetic-inductive device of magnetic induction sensor 11 and magnet steel 10 formation on the basis of common speed regulator, before shift knob 4 arrives extreme limit of travel, carried out the rotating speed of control machine at any time by the travel position of magnetic-inductive device inductive switch button 4, the slow acceleration and function of stepless speed regulation that can control are pointed in realization.
Current machine speed regulator 1-6 gear respectively corresponding 700-2500 turns, by speed regulator speed limit knob 7 regulation stall, start process: point shift knob 4 lifting, connecting rod 5 lifting simultaneously, switch push rod 2 lifting simultaneously, push-button reset spring 3 compresses simultaneously, touch and open main power switch 1, power supply is connected, speed regulator is energized, shift knob 4 continues lifting, connecting rod 5 continues lifting, hook magnet steel elevating bracket 9, magnet steel 10 is in company with magnet steel elevating bracket 9 together lifting, magnetic induction sensor (Hall) 11 perception magnet steel distance signal, the ratio (computing formula: critical distance/current distance=maximum speed/current rotating speed) of current magnet steel Distance geometry upper limit (UL) distance is calculated by speed regulator inside chip, electric tool rotating speed is controlled by result of calculation.When being lifted to extreme position, switch lock set button 12 can be pressed, now machine rotational speed can be fixed on the maximum speed of speed regulator setting.Otherwise the process that shift knob 4 declines can realize slowing down.
