Description

Technical Field

[0001] The utility model relates to the field of wheelchair equipment, in particular to a novel multifunctional wheelchair. Background Art

[0002] A wheelchair is a mobile assistive device designed for people with limited mobility, enabling them to carry out daily activities more independently. With the development of technology, electric wheelchairs have been introduced. Electric wheelchairs are equipped with motors and batteries. Users can easily control the wheelchair forward, backward, turn and other movements by operating the hand control lever without relying on human propulsion.

[0003] In order to improve the practicality of existing wheelchairs, the functions of the wheelchairs can be expanded. The user can install a placement frame on the wheelchair, and can place daily necessities or medicines in the placement frame. Some users will install an infusion stand on the wheelchair so that the user can receive an infusion while sitting in the wheelchair. However, the existing infusion stand basically requires the use of tools to tighten the bolts, and the infusion stand is installed on the wheelchair through the bolts. The existing installation requires the user to use tools to install the infusion stand on the wheelchair, which to a certain extent reduces the convenience of the wheelchair function expansion.

[0004] Therefore, it is necessary to provide a new novel multifunctional wheelchair to solve the above-mentioned technical problems. Utility Model Content

[0023] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0024] Please refer to Figure 1-Figure 7 ,in, Figure 1 The overall structure of the new multifunctional wheelchair provided by the utility model is shown as follows Figure 1 ; Figure 2 for Figure 1 The local structure schematic diagram shown; Figure 3 for Figure 2 The cross-sectional structure shown Figure 1 ; Figure 4 for Figure 1 The cross-sectional structure shown Figure 2 ; Figure 5 for Figure 2 The cross-sectional structure of the fixed block shown is shown in FIG. Figure 1 ; Figure 6 for Figure 1 The cross-sectional structure of the fixed block shown is shown in FIG. Figure 2 ; Figure 7 The overall structure of the new multifunctional wheelchair provided by the utility model is shown as follows Figure 2 .

[0025] In the specific implementation process, Figure 1-Figure 7As shown, a new type of multifunctional wheelchair includes an auxiliary chair 1, a connecting mechanism is fixedly provided on one side of the auxiliary chair 1, an infusion rod 2 is provided on the top of the connecting mechanism, and the bottom of the infusion rod 2 is movably extended to the inside of the connecting mechanism, the connecting mechanism includes a fixed block 3, one side of the fixed block 3 is fixedly connected to the side of the auxiliary chair 1, a circular groove 4 is provided inside the fixed block 3, two movable grooves 5 communicating with the circular groove 4 are provided inside the fixed block 3, the bottom of the infusion rod 2 is movably extended to the inside of the circular groove 4, two arc blocks 6 are fixedly provided on the outer surface of the infusion rod 2, and the tops of the two arc blocks 6 are movably extended to the inside of the two movable grooves 5 respectively, a support assembly is movably provided at the bottom of the infusion rod 2, a spring 7 is fixedly provided on the support assembly, and the bottom of the spring 7 is fixedly connected to the inside of the fixed block 3, the support assembly includes a support block 8, the support block 8 is movably provided in the circular groove 4, and the top of the spring 7 is fixedly connected to the bottom of the support block 8.

[0026] A telescopic rod 9 is provided inside the spring 7, and the top of the telescopic rod 9 is fixedly connected to the bottom of the support block 8, and the bottom of the telescopic rod 9 is fixedly connected to the inside of the fixed block 3. An annular groove 10 communicating with the circular groove 4 is provided inside the fixed block 3, and the outer surfaces of the two arc blocks 6 are movably connected to the inner surface of the annular groove 10. Two limiting grooves 11 communicating with the annular groove 10 are provided inside the fixed block 3, and the tops of the two arc blocks 6 are movably extended to the inside of the two limiting grooves 11 respectively, and the bottom of the spring 7 and the bottom of the telescopic rod 9 are fixedly connected to the side wall of the annular groove 10, and two arc grooves 12 are provided between the annular groove 10 and the circular groove 4, and the inner surfaces of the two arc grooves 12 are movably connected to the outer surfaces of the two arc blocks 6 respectively, and two connecting grooves 13 are provided at the top of the fixed block 3, and the inner surfaces of the two connecting grooves 13 are movably connected to the outer surfaces of the two arc blocks 6 respectively.

[0027] When the support block 8 moves upward or downward inside the fixed block 3, the support block 8 will drive the telescopic rod 9 to move upward or downward together. The telescopic rod 9 limits the movement trajectory of the support block 8 to prevent the support block 8 from separating from the fixed block 3. At the same time, the telescopic rod 9 supports the spring 7 to prevent the spring 7 from being entangled due to excessive squeezing.
