Detailed Implementation

[0024] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Depend on Figures 1 to 6 The present invention relates to a multifunctional wheelchair, comprising wheelchair frames 2 symmetrically arranged on the left and right sides of a crossbeam 1, a seat 3 disposed between the two wheelchair frames 2, an extension frame 4 fixedly installed on the front side of each of the two wheelchair frames 2, and a walker body 5 detachably installed on the extension frame 4.

[0026] In these embodiments, the main frame of the wheelchair is formed by wheelchair frames 2 arranged on both sides of the crossbeam 1, and then the seat 3 is installed in the main frame to form the main body of the wheelchair. Figure 1 As shown, the walker body 5 can be installed and removed by the extension frame 4 installed on the front side of the wheelchair body. This not only effectively combines the walker and the wheelchair, but also allows for convenient and flexible installation and removal, making it simpler to use.

[0027] By combining a walker and a wheelchair, the care of patients with diabetic foot ulcers not only provides the function of a wheelchair, but also allows caregivers to easily detach the walker when the patient needs to walk. The walker is stable and lightweight, effectively reducing the burden on the patient and making it suitable for various care situations, thus making it more convenient to use.

[0028] In some embodiments of a multifunctional wheelchair, the walker body 5 includes walker frames 7 symmetrically arranged on the left and right sides of the support 6, and a positioning rod 8 is fixedly installed on the walker frame 7. The positioning rod 8 is detachably installed on the extension frame 4.

[0029] In these embodiments, the main body of the walking aid 5 is composed of a bracket 6, a walking frame 7, and a positioning rod 8, such as... Figure 4As shown, the bracket 6 connects two walking aid frames 7. Each walking aid frame 7 is frame-shaped, with a positioning rod 8 fixedly installed inside. The walking aid body 5 is used by manipulating the crossbar at the top of the walking aid frame 7. The walking aid body 5 is installed on the extension frame 4 through the positioning rods 8 on the two walking aid frames 7, that is, the walking aid body 5 is "fitted" onto the wheelchair frame 2. This allows for a better integration of the walking aid body 5 within the space of the wheelchair body, ensuring a reasonable and stable connection, and making installation and retrieval convenient and efficient.

[0030] In some embodiments of a multi-functional wheelchair, support seats 9 are formed on opposite sides of the two extension frames 4. Positioning rods 8 are engaged in the support seats 9, and screws 10 are threaded onto the support seats 9, passing through the positioning rods 8. A through groove 11 is formed on the upper surface of the support seat 9, and locking blocks 12 are formed at both ends of the positioning rods 8. When the positioning rods 8 are engaged in the groove 11, the two locking blocks 12 are engaged at both ends of the groove 11.

[0031] In these implementations, such as Figure 6 As shown, the screw 10 is threaded onto one side of the support base 9, passes through the support base 9, extends into the slot 11 from one side, and is then threaded onto the other side of the slot 11. A through hole adapted to the screw 10 is formed on the positioning rod 8. The screw 10 passes through the through hole and is installed on the support base 9, thus fixing the positioning rod 8. When installing the positioning rod 8, the two walking frames 7 of the walker body 5 are simultaneously fitted onto the wheelchair frame 2, allowing the two positioning rods 8 to be respectively locked into the slots 11 of the corresponding support base 9. Simultaneously, the locking blocks 12 at both ends of the positioning rod 8 can be locked into the two ends of the slots 11 on the support base 9, ensuring that the positioning rod 8 can be quickly and accurately installed. Then, the screw 10 is rotated to extend into the support base 9, passes through the through hole on the positioning rod 8, and is tightened onto the other side of the support base 9, thus completing the fixing of the positioning rod 8. This ensures that the walker body 5 can be firmly installed on the wheelchair frame 2, making the operation convenient and efficient, and facilitating quick assembly and disassembly.

[0032] In some embodiments of a multifunctional wheelchair, the walker body 5 also includes a handrail 13, a travel wheel 14, and a base 15. The handrail 13 is fixedly connected between two walker frames 7, the travel wheel 14 is movably mounted at the front end of the walker frame 7, and the base 15 is fixedly mounted at the rear end of the walker frame 7. When the walker body 5 is mounted on the extension frame 4, the travel wheel 14 is used as an auxiliary wheel of the wheelchair frame 2, the handrail 13 is used as a handlebar of the wheelchair frame 2, and the base 15 is suspended on the wheelchair frame 2.

[0033] In these embodiments, the handrail 13 is fixed between the two walking aids 7, such as Figure 4As shown, the handlebar 13 further expands the optional ways to operate the walking aid body 5, making it more flexible to use. The cooperation between the travel wheels 14 and the base 15 helps to improve the stability of the walking aid body 5 during movement. After the walking aid body 5 is installed on the wheelchair body, the travel wheels 14 are used as auxiliary wheels of the wheelchair frame 2, which can further improve the stability of the wheelchair. The handlebar 13 is used as the handlebar of the wheelchair frame 2, making it easier for caregivers to operate. The base 15 is suspended on the wheelchair frame 2, reducing the impact on the wheelchair body, making the combination of the two more ingenious.

[0034] In some embodiments of a multi-functional wheelchair, the wheelchair also includes a main wheel 16, a steering wheel 17, and a foot pedal 18. The main wheel 16 is movably mounted in the middle of the wheelchair frame 2, the steering wheel 17 is movably mounted in the lower end of the wheelchair frame 2, and the foot pedal 18 is fixedly mounted in the rear end of the wheelchair frame 2.

[0035] In these implementations, such as Figure 1-3 As shown, the main wheel 16 is movably mounted on the vertical bar in the middle of the wheelchair frame 2 via a pivot, and the steering wheel 17 is movably mounted on the end of the rear vertical bar of the wheelchair frame 2. The foot pedal 18 is fixed to the diagonal bar at the rear end of the wheelchair frame 2. The cooperation of the main wheel 16 and the steering wheel 17 ensures the stable use of the wheelchair, and the foot pedal 18 facilitates the placement of the patient's feet.

[0036] In some embodiments of a multi-functional wheelchair, a protective plate 19 corresponding to the seat 3 is fixedly connected between two extension frames 4, and the extension frames 4, the protective plate 19 and the seat 3 together form a storage box 20.

[0037] In these implementations, such as Figure 3 As shown, the protective panel 19 is positioned opposite the seat 3, and the two together form a storage box 20, which expands the storage space on the basis of the wheelchair body, making it more convenient for nursing staff to use for patient care.

[0038] In some embodiments of a multi-functional wheelchair, the seat 3 includes a seat 21, a backrest 22, and a leg rest 23. The seat 21, backrest 22, and leg rest 23 are all fixedly connected between two wheelchair frames 2 and fixedly mounted on the crossbeam 1. The backrest 22 is fixedly mounted above the seat 21, and the leg rest 23 is fixedly mounted below the seat 21.

[0039] In these embodiments, the seat 3 for carrying the patient is formed by the cooperation of the seat 21, backrest 22 and legrest 23, and together with the aforementioned wheelchair body, it ensures that the patient can sit stably and is more convenient to use.

[0040] In some embodiments of a multi-functional wheelchair, a handle 24 is formed on the wheelchair frame 2 near the backrest 22. An armrest 25 is formed on the wheelchair frame 2 corresponding to the seat 21.

[0041] In these embodiments, the handle 24 facilitates the movement of the wheelchair by caregivers. The armrests 25 facilitate the placement of the patient's arms, thereby improving riding comfort.

[0042] When this utility model is in use, when the patient needs to use the walking aid body 5, the caregiver unscrews the screw 10 and removes the walking aid body 5 from the wheelchair for the patient to use.
