Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. The "up" and "down" directions described in this manual correspond to the up and down directions in Figure 1 respectively; when sitting on a wheelchair, the occupant faces the "front" direction described in this manual, The direction facing the back is the "rear" side described in this manual, while the direction of the occupant's left hand is the "left" side described in the manual, and the direction of the right hand is the "right" side described in the manual.

Referring to accompanying drawings 1 and 2, the utility model discloses a wheelchair, comprising a vehicle frame 1, a pair of front wheels 2 and a pair of rear wheels 3 respectively rotatably connected to the front and rear sides of the vehicle frame 1 . The vehicle frame 1 comprises: a pair of upper horizontal support rods 11 positioned at the left and right sides of the seat, a pair of lower horizontal support rods 12 respectively located below the pair of upper horizontal support rods 11, a pair of upper horizontal support rods 11 and a pair of horizontal support rods respectively. The middle support structure connected with the lower horizontal support rod 12, the front fork support rod 15, the rear wheel support rod 16, the push rod 13 and the handrail rod 14, the rear wheel support rod 16 is connected with the upper horizontal support rod 11 and the lower horizontal support rod on the same side pole 12.

A mounting plate 4 is also connected between the upper horizontal support rod 11 and the lower horizontal support rod 12. The mounting plate 4 is located in front of the rear wheel 3. The transmission gear 5 is connected to the mounting plate 4 in rotation. The outer end surface of the transmission gear 5 is A sleeve 51 is fixedly connected to the top, and a rocking handle 6 is detachably inserted into the sleeve 51 . The rocking handle can be flexibly installed or removed according to the needs of whether to exercise.

Rear wheel 3 comprises rim 31, hand wheel 32, rear wheel hub 33, flywheel 35 and rear axle 34, wherein, rim 31 is connected to the outer ring of rear wheel hub 33 by a plurality of spokes, flywheel 35 and rear wheel hub 33 It is fixedly connected with the outer ring of the rear wheel hub 33, and the rear wheel shaft 34 passes through the rear wheel hub 33 and is fixedly connected with the rear wheel support rod 16. The flywheel 35 and the transmission gear 5 are tensioned by a chain. In this way, when the user sits on the wheelchair and pulls the rocking handle forward or backward with both hands at the same time, the transmission gear 5 can be driven to rotate, and the flywheel 35, the rear wheel hub 33, and the rim 31 can be driven to rotate through the chain to realize the advancement of the wheelchair; And because the transmission gears 5 on the left and right sides are independent of each other, the rear wheel on one side remains motionless, and the rear wheel on the other side rotates to realize that the wheelchair turns left or turns right. The wheelchair of the present utility model can brake the rear wheel 3 through the independent braking structure, and the brake lever can also be arranged on the rocking handle, and the rear wheel can be braked by pressing the wheel rim backwards through the rocking handle. The transmission ratio between the transmission gear 5 and the flywheel 35 is greater than 1.

The front part of the vehicle frame 1 is fixedly equipped with a limiting plate, the limiting plate 41 protrudes from the outside of the vehicle frame 1, and blocks in front of the rotation path of the crank handle 6, which refers to the rotation path of the crank handle and the transmission gear. The center of rotation of is the area swept by the rotation of the center of the circle. In this embodiment, each mounting plate 4 is provided with a limiting plate 41, which can prevent the rocking handle 6 from falling forward and cannot be reached by a user sitting in a wheelchair. In other embodiments, it can also be Two limiting plates are respectively arranged on each mounting plate, and the two limiting plates respectively limit the range of motion of the rocking handle in the front and rear directions.

The utility model can increase the activities of the user's arm parts and waist and back muscles, so as to achieve the purpose of exercising and keeping fit.

The above-mentioned embodiments are only to illustrate the technical concept and characteristics of the present utility model, and its purpose is to enable those familiar with this technology to understand the content of the present utility model and implement it accordingly, and not to limit the protection scope of the present utility model.
