Summary of the invention
For the deficiencies in the prior art, the utility model provides the change over switch that a kind of structure is simple, switching action is reliable and stable.
For achieving the above object, the utility model provides a kind of change over switch, include housing, described housing is provided with an annular groove, the inner ring surface of described annular groove is provided with at least two gear grooves, described housing is also equiped with the switching device shifter carrying out switching between each gear groove, described switching device shifter includes rotating shaft, torsion spring, oval cam bit, slide and rotatable lamella, described rotating shaft is located on housing, and the inner of described rotating shaft extends in annular groove, described oval cam sheet is installed on the inner end of rotating shaft, oval cam sheet is provided with a radial projection along its short-axis direction, described radial projection is also provided with axial projection, described rotatable lamella is positioned at annular groove, and correspondence offers locating rotation hole on the bottom surface of described annular groove, on the lower surface of described rotatable lamella, correspondence is provided with the location inserting column forming pivotal fit with described locating rotation hole, the upper surface of described rotatable lamella offers a radial slippage groove, described slide is flush-mounted in described radial slippage groove, and can slide along described radial slippage groove radial alignment, described slide is provided with slide block in one end of its glide direction, described rotatable lamella is also provided with a rotatable lamella block at the radial outside of described slide block, Compress Spring has been clamped between described rotatable lamella block and slide block, and under the effect of described Compress Spring, slide block is formed to abut with the outer peripheral face of described oval cam sheet and coordinates, described slide is provided with gear projection at the other end of its glide direction, and when the minor axis end outer peripheral face of cam bit turn to abut against with slide block time, described gear projection is embedded in gear groove, when the longitudinal end outer peripheral face of cam bit turn to abut against with slide block time, described gear projection and gear groove keep being separated, described torsion spring set is loaded on the inner of rotating shaft, and be provided with two and extend in parallel end, the axial projection on described cam bit and the gear projection on slide are all clamped in two of torsion spring and extend in parallel between end.
The beneficial effects of the utility model are: adopt said structure, during switching, people pass through rotating shaft, thus first drive oval cam bit to rotate, axial projection on cam bit will promote one of them elongated end generation deformation of torsion spring, coordinate because described slide block abuts against with the outer peripheral face of described oval cam sheet, therefore the slippage of drive slide radial alignment is also progressively compressed Compress Spring by the rotation of cam bit, when the longitudinal end outer peripheral face on cam bit turn to abut against with slide block time, now Compress Spring obtains maximum compression, the gear projection be positioned on the slide other end will keep being separated with gear groove, after this, under the effect of another elongated end of torsion spring, slide and rotatable lamella will follow rotating shaft to rotate, and Compress Spring resets gradually in the process rotated, promote slide reverse slide, until when turning to next gear groove, the minor axis end outer peripheral face of cam bit just in time turns to and abuts against with slide block, under the effect of Compress Spring, described gear projection will be pushed in this gear groove, thus realize the gear switch of change over switch.In sum, because simple, the used parts of the utility model structure are less, therefore production cost is low, and switching action is reliable and stable.
The inner end that the utility model can be set to described rotating shaft is further provided with a bumping square, described bumping square is also provided with the projection of one and rotating shaft concentric, oval cam bit offers one with the square groove of described bumping square phase scarf, in the radial slippage groove of described rotatable lamella, correspondence is provided with the jack forming pivotal fit with described projection, and described jack and location inserting column concentric.
Adopt said structure, by coordinating of bumping square and square groove, cam bit can be made to be formed with rotating shaft and be fixedly connected with reliably; And pass through the pivotal fit of described projection and jack, then rotating shaft and rotatable lamella effectively can be avoided to radially slide in rotation process, thus make switching action more reliable and more stable.
The utility model also can be set to the flange described rotating shaft being also provided with restriction torsion spring axial endplay further.
Adopt said structure, by setting up flange, can effectively avoid torsion spring, in rotation process, axial endplay occurs, thus also make switching action more reliable and more stable.
The outer end that the utility model also can be set to described rotating shaft further passes outside housing, and is equiped with knob, and knob is provided with direction board.
Adopt said structure, by setting up direction board, people can be convenient to and understand change over switch gear stages residing at that time in real time, avoiding misoperation.
