[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1 As shown, the utility model provides a rainproof medical wheelchair, including a wheelchair body 1, a vertical storage groove 2 is opened on the wheelchair body 1, a rotating shaft 4 that can move up and down along its vertical direction is arranged in the storage groove 2, and a shielding plate 5 is rotatably sleeved on the rotating shaft 4.

[0029] When users need to protect from rain or sun, refer to Figure 2 As shown, when the rotating shaft 4 is lifted to the notch of the storage slot 2 and the shielding plate 5 is rotated about the rotating shaft 4, the shielding plate 5 is parallel to the base of the wheelchair body 1 and is located above the wheelchair body 1, so that the shielding plate 5 can shield the user located on the base of the wheelchair body 1 from rain and sun, and a limiting component for fixing the shielding plate 5 is also provided on the wheelchair body 1.

[0030] Therefore, this device can provide rain protection for the user without the need for the user or caregiver to maintain the rain shield, and when there is no rain, the shielding plate 5 can be stored back into the storage slot 2 to restore the wheelchair body 1 to an open structure.

[0031] In order to ensure the stability of the shielding plate 5 when it is unfolded, in this embodiment, the specific structure of the limit assembly is as follows: Figure 3 and Figure 4 As shown, the limiting assembly includes a mounting groove 6 with an opening on the wheelchair body 1 facing the shielding plate 5, a driving member and a wedge block 8 are arranged in the mounting groove 6, the wedge end of the wedge block 8 is arranged close to the opening of the mounting groove 6, and the wedge block 8 can slide out or slide into the mounting groove 6, and the other end of the wedge block 8 is connected to the driving member, which is fixed in the mounting groove 6 to drive the wedge block 8 to slide out or slide in.

[0032] A limiting groove 501 matching with the wedge block 8 is provided on the side wall of the shielding plate 5. When the wedge block 8 enters the limiting groove 501 under the action of the driving member, the shielding plate 5 is fixedly connected via the limiting assembly.

[0033] In order to realize the automatic sliding out and sliding in of the wedge block 8 in the installation groove 6, in this embodiment, the structure of the driving member is as follows: the driving member includes a spring 7, and the two ends of the spring 7 are fixedly connected to the wedge block 8 and the inner wall of the installation groove 6 respectively. When the spring 7 is freely extended without external force, the wedge end of the wedge block 8 slides out of the installation groove 6 under the action of the elastic force of the spring 7.

[0034] When the shielding plate 5 rotates, the shielding plate 5 first presses against the wedge surface of the wedge block 8, and then the wedge block 8 slides into the installation groove 6 and compresses the spring 7. When the limiting groove 501 is opposite to the installation groove 6, under the action of the elastic force of the spring 7, the wedge end of the wedge block 8 is inserted into the limiting groove 501, so that the shielding plate 5 is fixedly connected to the wheelchair body 1.
