Fig. 4 is the structural representation of the utility model pedal.
Detailed description of the invention
With reference to the accompanying drawings detailed description of the invention of the present utility model is made a detailed explanation below.
embodiment 1
According to shown in Fig. 1 to Fig. 4, a kind of wheelbarrow with auxiliary wheel described in the present embodiment, include vehicle body 1, the both sides of described vehicle body are respectively provided with a pedal 2, described pedal is hinged by adapter shaft and vehicle body, described body top section is provided with source switch 6, the lower surface of a described pedal installs the auxiliary wheel system with Liftable auxiliary wheel, upper surface is provided with the switch B52 controlling auxiliary wheel and fall, and the upper surface of pedal described in another is provided with the switch A51 controlling auxiliary wheel and pack up.
Described auxiliary wheel system includes described auxiliary wheel 4, the strut bar 3 of described auxiliary wheel is installed, to be molded over below described pedal and the mount pad 20 be rotationally connected with described strut bar, with the drive spindle 5 be rotationally connected in the middle part of strut bar, and the slide block 7 to be rotationally connected with the drive spindle other end, described skid is arranged in described pedal; The drive system driving described skid is also installed in described pedal.
Described drive system includes the motor 8 be arranged in pedal, and the leading screw 9 be fixedly connected with described motor output shaft, described screw mandrel is connected by screw-driven with described slide block.
Described screw mandrel is parallel with the direction of slip of described slide block, and the side of described slide block forms and coordinates with described screw mandrel the tooth bar be in transmission connection.
Described pedal end offers the motor installation cavity 21 installing described motor, in pedal, the inner side of motor installation cavity offers leading screw installation cavity 24, the position that pedal end differs from motor installation cavity offers slide rail 22, and slide rail is communicated with described leading screw installation cavity perpendicular to the side in skid direction.
The auxiliary wheel container cavity 23 holding collapsed state auxiliary wheel is offered bottom described pedal.
Described source switch, switch A, switch B are electrically connected with controller input end respectively, and described motor is electrically connected with controller output end.
When using the utility model, user opens pedal, opening power, and when a pin steps down on switch B, motor starts to rotate, and drives leading screw, thus drives skid, makes slide block drive drive spindle, finally makes auxiliary wheel fall.User can by auxiliary wheel, cosily another pin is stepped on another pedal, as another pin PS (Push Switch) A, motor starts to rotate, and drives leading screw, thus drives skid, slide block is made to drive drive spindle, finally make auxiliary wheel pack up, do not need extra operation, fixed type auxiliary wheel can be solved again and to ride inconvenient problem.
embodiment 2
