Abstract
The utility model discloses a foot-operated variable-speed switch, aiming to provide a foot-operated switch, which can open or close a power supply and adjust the speed. The foot-operated variable-speed switch provided by the utility model comprises a switch shell, a pedal and a push switch controlled by the pedal, and is characterized in that a rheostat is arranged in the switch shell, and the resistance value of the rheostat is adjusted by pushing the pedal; and the rheostat adopts a magnetic induction rheostat, the resistance value of the rheostat is adjusted by changing the distance between an induction sheet and a magnetic pole in the magnetic induction rheostat via the pedal, and the induction sheet is not in contact with the magnetic pole. The foot-operated variable-speed switch provided by the utility model is mainly used in a control switch of a coiling machine.
Description
Technical field
The utility model relates to a kind of switch, relates in particular to a kind of pedal gear change switch.
Background technology
The pedal gear change switch often uses on not easy-to-use hand-guided machines such as machinery, the operation of control machine when it can make both hands carry out other actions.It uses very extensive at coiler, but existing coiler divides unwrapping wire system and cam system two parts, control by two foot switchs, the coiler that also has speed governing when lopping needs to regulate on machine with hand, inconvenience when practical operation, make people's crank easily, the lopping effect is undesirable.
Summary of the invention
The utility model discloses a kind of pedal gear change switch, he can carry out speed governing to another machinery in switch machinery, control the problem that produces in the practical operations such as people's crank, lopping effect be undesirable that makes to solve two foot switchs of existing need.
For achieving the above object, technical solution of the present utility model is: a kind of pedal gear change switch, comprise switch housing, pedal and pass through the foot-controlled push switch, it is characterized in that: in switch housing, be provided with rheostat, by pedal travel standardsizing rheostat resistance.
Further, described rheostat is the magnetic induction rheostat, regulates distance between two poles from the standardsizing rheostat resistance by pedal.
Further, change sensing chip in the magnetic induction rheostat and distance between two poles from coming the standardsizing rheostat resistance by pedal, sensing chip does not contact with magnetic pole.
The beneficial effects of the utility model are: the magnetic induction rheostat is set in the pedal gear change switch and changes the purpose that the rheostat resistance changes machine rotational speed by pushes pedals change sensing chip and distance between two poles from reaching, number of switches when having reduced control machinery, make center of gravity firm and simple to operation, control can reach good packing effect easily.
Description of drawings
Accompanying drawing is a structural representation of the present utility model;
Among the figure: 1-switch housing, 2-pedal, 3-push switch, 4-rheostat, 5-sensing chip.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further details.
Referring to accompanying drawing, the utility model comprises switch housing 1, pedal 2 and the push switch of controlling by pedal 23, it is characterized in that: be provided with rheostat 4 in switch housing 1, by pedal 2 motion standardsizing rheostats 4 resistances.
Described rheostat 4 is the magnetic induction rheostat, regulates distance between two poles from standardsizing rheostat 4 resistances by pedal.
Change sensing chip 5 and distance between two poles in the magnetic induction rheostats from coming standardsizing rheostat 4 resistances by pedal 2, sensing chip 5 does not contact with magnetic pole.
Foot switch and coiler that the utility model is produced join, turn on the power switch when bringing into use coiler, and downward pushes pedals 2, push switch 3 unclamps the operation of energized coiler under pedal 2 drives.Now can be carried out to ring manipulation, thus when being carried out to ring manipulation by the degree of trampling to pedal 2 change sensing chip 5 with distance between two poles from the resistance that changes rheostat 4 to change the lopping speed of coiler.Pedal 2 being unclamped push switch 3 after finishing using, to close the unwrapping wire system out of service, will enclose good wire rod this moment and unload preparation again and work next time.
Claims (3)
