Abstract
The invention discloses a pedal turning mechanism which comprises a vertical column main body, a rotary motor installed at the upper part of the vertical column main body and a straight-tooth cylindrical gear which is driven by the rotary motor to rotate, wherein one sector gear is hinged on the vertical column main body, and the tooth side of the sector gear is meshed with the straight-tooth cylindrical gear; one small connecting rod is fixed with the sector gear, one end of the small connecting rod is hinged by the same hinged point of the sector gear, and the other end of the small connecting rod is hinged on the upper end of a large connecting rod; a lifting lug is arranged on the pedal; the lower end of the large connecting rod is hinged on the lifting lug; the pedal is hinged at the lower end of the vertical column main body; and the rotary motor drives the straight-tooth cylindrical gear to rotate and draws the pedal to turn folded upwards or turn unfolded downwards through the sector gear, the small connecting rod and the large connecting rod. The mechanism has a simple structure, is easy to operate, can well save space after turning, can adjust moving angle range of the pedal, and is suitable for being promoted and used on wheelchairs and the like.
Description
Technical field
the present invention relates to a kind of pedal mechanism that turns back.
Background technology
are for often requiring the pedal on it to can these in some cases on the seat of some specific uses such as wheelchair, and are preferably simple in structure, easy to operate, to be convenient to user to greatest extent.
Summary of the invention
of the present invention provide a kind of simple in structure, stable, and the pedal of being convenient to the control mechanism that turns back.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
a kind of pedal mechanism that turns back; Comprise upright post main, be installed in the rotary motor on described upright post main top, drive the straight spur gear that rotates by described rotary motor; Sector gear is hinged on the described upright post main and its flank is meshed with described straight spur gear; Small rod fixes with described sector gear, and an end hinged with the pin joint identical with described sector gear; The other end of described small rod is hinged on the upper end of a big connecting rod; Described pedal is provided with hanger; The lower end of described big connecting rod is hinged on the described hanger, and described pedal is hinged on the lower end of described upright post main, and described rotary motor drives that described straight spur gear rotates and affects described pedal upwards to turn back to pack up or turn down through described sector gear, described small rod and described big connecting rod and open.
preferably, the pin joint of described big connecting rod and described hanger is higher and further from described pedal, when described big connecting rod rose, described pedal turned down and opens than the pin joint of described pedal and described upright post main; When described big connecting rod descended, described pedal was upwards turned back and is packed up.
preferably; Described straight spur gear is fixed on through plain washer, wave washer and nut on the screw of a hollow, and described screw is enclosed within on the output shaft of described rotary motor and through the holding screw that radially screws in and fixes.
the invention has the beneficial effects as follows: simple in structure, easy to operate, can save the space well after turning back, and can adjust the activity point of view scope of pedal as required, be suitable on wheelchair etc., promoting the use of.
