Abstract

The utility model discloses a wheelbarrow for recreation. The utility model is concretely formed by that a balancing device for cycle body which is higher than a saddle is connected with the saddle or the upper end of a frame, and a wheel is connected with the saddle by the upright frame; the inner ring of bearing and a shaft which are adopted by the wheel rotate, and the outer ring of bearing and a shafting frame connecting piece are immovable; the shaft is provided with a disk chuck, and the disk chuck is welded with the shaft to form a whole; a shaft bearing is arranged between the disk chuck and a crank, and the shaft bearing is fixed on the shaft by a circlip for shaft; the outer ring of bearing is matched and arranged in the hole of the shafting frame connecting piece, and is fixed by a circlip for hole. The utility model fully utilizes the dynamic balance principle, making the gravity centre of a rider raised with the aid of the balancing device, and further, the balance of the movement is kept.

Description

Wheelbarrow for recreation

The utility model relates to a kind of amusement apparatus, particularly a kind of amusement wheelbarrow.

In the past,, once used a kind of wheelbarrow in acrobatics circle and indivedual public place of entertainment.But the balance of this car on the go relies on bicyclist's self center of gravity control fully, and much less common amusement fan, professional acrobat also must can grasp the balance method of this car on the go by exercising device.In addition, the axle of this car and watt box structure that is connected to of vehicle frame, accuracy of manufacture is had relatively high expectations, complex process, therefore easy decentraction and the bearing deformation that axle takes place in manufacturing and installation process makes the spindle unit et out of order.

The purpose of this utility model provides a kind of amusement wheelbarrow, and it adopts unique balancing device, makes the bicyclist be very easy to grasp the balance method of this wheelbarrow on the go.

The purpose of this utility model is achieved in that and adopts the balancing device that is higher than saddle, links to each other with saddle or vehicle frame upper end, and wheel is connected by upright vehicle frame with saddle, and wheel is controlled crank by pedal, thereby rotates forward or backward by the crank actuating spindle.When axle rotated, bearing inner ring rotated with axle, and outer race maintains static with the pedestal attaching parts.

Be provided with floral disc on said axle, floral disc and beam warp are welded into one, between floral disc and the crank bearing are housed, and are fixed on the axle with circlip for shaft, and outer race is fitted in the pedestal attaching parts hole, and fixes with circlip for bore.Bearing inner ring and axle, outer race and pedestal attaching parts are flush fit.Pedestal attaching parts and vehicle frame are fastening by tightening screw, and crank is fixed on the two ends of axle by pin for suppressing metal.

Because the utility model pedestal attaching parts adopted ring-like integral structure, and with vehicle frame be the branch body component, the socket mode is adopted in both connections, and fastening with screw.Screw and drift bolt aperture are free-running fit, can adjust when assembling, have solved the decentraction problem of the axle that other connects, fastening method is easy to generate when manufacturing, assembling.

Because the utility model has adopted technique scheme, thereby has made full use of principle of mobile equilibrium, makes the bicyclist by balancing device, center of gravity is improved, and then the balance in keeping moving.

Fig. 1 is a kind of integral structure scheme drawing of the utility model.

Fig. 2 is the left view of Fig. 1.

Fig. 3 is the utility model axletree installing condition scheme drawing.

Fig. 4 is the utility model pedestal attaching parts and bearing inner and outer rings assembly relation scheme drawing.

Below in conjunction with Fig. 1-4 and embodiment in detail the utility model is described in detail.

As shown in the figure: 1 for being higher than the car body balancing device of saddle horizontal surface, this device links to each other with saddle 2 or upright frame part 3 upper ends, saddle 2 is connected by inserting mode with vehicle frame 3 and uses the screw external fixation, wheel 4 is connected as a single entity by frame part 3 with saddle 2, and wheel is controlled cranks by pedal 5, and is rotated forward or backward by crank actuating spindle 6, when axle rotates, bearing inner ring A rotates with axle, and outer race B and pedestal attaching parts maintain static, and C is a ball.

On said axle 6, be provided with floral disc 69, floral disc and axle 6 are through being welded into one, between floral disc and the crank 63 bearing 62 is housed, and by circlip for shaft 64 be fixed in the axle 6 on, outer race is fitted in pedestal attaching parts 68 holes, and it is fixing with circlip for bore 61, bearing inner ring is flush fit with axle, outer race and pedestal attaching parts, pedestal attaching parts 68 is fastening by tightening screw 67 with vehicle frame 3, and crank 63 is fixed on the two ends of axle 6 by pin for suppressing metal 65.

Be provided with the elastic caoutchouc grip in car body balancing device of the present utility model 1 upper end, the car body balancing device can adopt inserting mode to be connected with saddle or upright vehicle frame, and uses the screw external fixation.
