Detailed ways

The specific embodiment of the utility model will be further described below in conjunction with accompanying drawing:

As shown in Figures 1 and 2, a wheeled walker for a variable wheelchair includes a vehicle frame 1, a base 3 formed by fixed left and right seat tubes 13 on the left and right frame tubes 2, connected to the The pedal 5 that two seven-shaped frames 4 on the front leg tube 10 of side frame pipe 2 middle and lower parts and one end of seven-shaped frame 4 are connected, the rear wheel that vehicle frame 1 rear portion is connected by hinge 6. The side frame upright pipe 17 is inserted in the side frame pipe 2 through the middle cover 18, and the middle cover 18 has a screwdriver 19 for controlling the degree of tightness, by which the height of the side frame upright tube 17 can be adjusted. The top of the side frame upright pipe 17 is bent into a handle, the handle is provided with a non-slip handle cover 20, and the handle below is provided with a brake handle 21. Backrest 7 is installed between the left and right frame upright pipes 17, as further optimization of the utility model, backrest 7 is respectively installed on the left and right side frame upright pipes 17 by two backboards 8 and connects two backboards 8 The elastic band 9 is composed of the elastic band 9. Because the elastic band 9 has elasticity, the backing plate 8 can be installed on the inside or outside of the side frame vertical pipe 17. In this embodiment, when the utility model is used as a walker, the backing plate 8 is installed On the inner side of the side frame vertical pipe 17, the rest of the walker is formed (as shown in Fig. 4). When the utility model was used as a wheelchair, the back plate 8 was installed on the outside of the side frame upright pipe 17 to form the backrest of the wheelchair.

With reference to Fig. 1, Fig. 2 and Fig. 3 again, the lower end of the side frame pipe 2 is connected with the front pipe 22 of the side frame and the rear bend pipe 25 of the side frame respectively, and the two ends of the front leg pipe 10 are respectively fixed on the side frame pipe 2 and the front pipe 22 of the side frame On the top, one end of the seven-shaped frame 4 is installed on the front leg tube 10 through two movable legs 23 distributed in parallel, and the other end is connected with the pedal 5 through a rotatable shaft. Rotate to be vertical position, also can pedal 5 rotate to be level. Through the above structure, the effect of turning over the pedal 5 is formed. When the utility model is used as a wheelchair, the pedal 5 is installed on the front leg pipe 10 through the movable foot frame 23, and the person's feet can be placed on the pedal 5. Secondly, the pedal 5 can also be made It can increase rough surface corrugations or grooves, etc., so that the rider's feet can be placed on the pedals 5 smoothly (as shown in Figure 1 and Figure 2); when the utility model is used as a walking aid, by using tools Remove the movable tripod 23 and get final product (as shown in Figure 4). Two front wheels 24 are installed on the front end of side frame front tube 22, and one end of side frame rear elbow 25 is connected with side frame pipe 2 by hinge 6, and rear wheel 26 is installed on the other end.

As shown in FIG. 6 , the hinge allows the side frame rear bend pipe 25 to achieve a rotation of 0-120 degrees. In this embodiment, a protruding screw hole 27 is made on the bottom surface of the side frame rear elbow 25, and a locking handle 28 with an opening is made on the bottom surface of the side frame tube 2 by welding or the like. The screw hole 27 is connected with the locking handle. The opening of the handle 28 matches, and the screw hole 27 can be connected and fixed with the locking handle 28 through the locking screw rod, so as to play the role of reinforcement. When the utility model needs to be folded, the locking screw rod is removed, and the rear elbow 25 of the side frame can be folded upwards. On trailing wheel 26, the rear brake brake 29 of stop is also installed, and this rear brake brake 29 is simple brake.

Referring to Fig. 3 and Fig. 5 again, a folding mechanism is installed under the base 3, the folding mechanism is an X-shaped cross frame 12 connected by a rotating shaft 11, and the two ends of the cross frame 12 are connected to the seat tube 13 and the vehicle frame 1 respectively , the vehicle frame 1 can fold the vehicle frame 1 horizontally together (as shown in Figure 5) through the folding mechanism, and the seat 14 is formed by installing Velcro between the left and right seat tubes 13, and a support plate is received under the seat tube 13 15. The radial section of the support plate 15 is perpendicular to the seat tube 13, and a connecting rod 16 extends from the middle of the support plate 15, and the connecting rod 16 is locked on the side frame tube 2 by bolts, so that the support plate 15 is fixed on the side frame On the pipe 2, it plays a supporting role to the seat pipe 13.

The specific embodiment of the utility model is as follows:

The wheeled walker of the variable wheelchair described in the utility model can achieve the dual-purpose use effect of a wheelchair or a walker after simple disassembly or assembly. When the utility model is used as a walker, as shown in the figure As shown in 1, the backing plate 8 is installed on the inboard side of the side frame upright pipe 17, which constitutes the supporting hand of the walker, and the movable tripod 23 is dismantled simultaneously. When the utility model was used as a wheelchair, as shown in Figure 4, the backboard 8 was installed on the outside of the side frame upright pipe 17, forming the backrest of the wheelchair. The footrest 5 is installed on the front leg pipe 10 through the movable leg frame 23 by using a tool, so that the person's foot can be placed on the footrest 5 . When it needs to be folded, as shown in Figure 5, remove the support plate 15 and the Velcro on the seat and the pedal 5, remove the locking screw at the same time, fold up the rear elbow 25 of the side frame, and rotate and screw it at the same time. Hand 19 makes side frame upright pipe 17 all inserted in side frame pipe 2, through above-mentioned operation, makes the utility model can realize folding, effectively less volume. The basic principles and main features of the present utility model and the advantages of the present utility model have been shown and described above. Those skilled in the art should understand that the utility model is not limited by the above-mentioned embodiments.
