Detailed ways

The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

As shown in FIG. 1 to FIG. 3 , a multifunctional wheelchair provided by the present invention includes a wheelchair body 1 and armrests 11 installed on the left and right sides of the wheelchair body 1 , and also includes a fixed body 2 fixedly connected to the armrest 11 . , the inversion body 3 whose left end is connected with the middle rotating shaft of the upper end of the fixed body 2 , and the placing table 4 whose left end is connected with the rotating shaft at the lower right end of the inversion body 3 . In this way, the fixed body 2 is stably fixed on the armrest 11. When the old man does not need to read and eat, the placing table 4 which occupies a large space is hoisted under the armrest 11 through the inversion body 3 and the fixed body 2, which does not hinder the normal operation of the old man. Activities; when the elderly need to do daily activities such as reading, writing, eating, etc., turn the placing table 4 to the top of the legs by hand, and finally, the left end surface of the inverting body 3 is attached to the top surface of the fixed body 2, and the placing table 4 is placed at the same time. The right end face of the inverting body 3 is attached to the right end face of the inverting body 3 to support the placing table 4, and the end of the placing table 4 is placed flat and stably above the legs of the elderly, which is very convenient.

In order to optimize the structure of the present utility model, it also includes a connecting plate 41 installed on the right end surface of the placing table 4, the placing table 4 is connected with the rotating shaft of the turning body 3 through the upper end of the connecting plate 41, and the right end surface of the placing table 4 is opened There are at least two movable grooves 42 distributed parallel to the horizontal plane and symmetrically distributed up and down. The connecting plate 41 is formed with sliding protrusions that are aligned and fitted in the movable grooves 42 . When the old man places the placing table 4 stably, he can directly push the placing table 4 back and forth, and the limit grooves on the placing table 4 and the sliding protrusions on the connecting plate 41 move relative to each other, which is convenient for the old man to make appropriate adjustments according to his own needs.

In order to make it more convenient for the elderly to store the placing table 4, the placing table 4 includes a first folding board 44 and a second folding board 45 connected to the rotation axis of the first folding board 44 and stacked on the first folding board 44.
