DETAILED DESCRIPTION
[0020] The utility model is further described below in conjunction with specific drawings and embodiments.
[0021] like Figure 1 to Figure 4 As shown, the embodiment discloses a combined multifunctional wheelchair, including a chair frame 1, wheels 2 are installed on both sides of the chair frame 1, a seat cushion 3, a backrest 4 and armrests 5 are installed on the chair frame 1, and a detachable walker 6 is installed at the rear of the chair frame 1. The detachable walker 6 can be used to push the wheelchair when installed on the chair frame 1, and can be used as a walker alone after being removed.
[0022] like Figure 2 to Figure 4As shown, in this embodiment, the detachable walker 6 is mainly composed of two side uprights 61, a lower cross beam 62 and an upper cross handle 63. Vertical plug-in tubes 7 are respectively provided on both sides of the rear part of the chair frame 1. The lower ends of the two side uprights 61 are respectively inserted into the two vertical plug-in tubes 7, and locking nuts 8 are installed on the side walls of the vertical plug-in tubes 7; the two ends of the lower cross beam 62 are respectively fixedly connected to the lower ends of the two side uprights 61, and the lower cross beam 62 is a circular arc shape bent forward; the two ends of the upper cross handle 63 are connected to the upper ends of the two side uprights 61.
[0023] When the detachable walker 6 is installed on the chair frame 1, the locking nuts 8 on both sides can be tightened to fasten the two side uprights 61 in the vertical plug-in tube 7. The upper cross handle 63 of the detachable walker 6 can be used to push the wheelchair. Since the side uprights 61 of the detachable walker 6 can be adjusted up and down in the position of the vertical plug-in tube 7, the height of the upper cross handle 63 can be adjusted according to the height of the person pushing the wheelchair. Compared with ordinary wheelchairs with non-adjustable push handles, it is more comfortable to use. When the patient needs to use the detachable walker 6 to assist in walking, the locking nuts 8 on both sides are loosened, and the entire detachable walker 6 can be easily removed. Since the lower cross beam 62 is a circular arc that bends forward, the patient's legs will not be blocked by the lower cross beam 62 when walking, and there can be a larger range of activities, a more natural walking gait, and more comfortable use.
[0024] like Figure 2 to Figure 4 As shown, in this embodiment, a 7-shaped head 64 is installed at the upper end of the side upright rod 61, and the upper horizontal handle 63 is a U-shaped head with bent heads at both ends. The bent heads at both ends of the upper horizontal handle 63 are respectively connected to the other end of the 7-shaped head 64 through a locking pin 65. In this way, the angle between the upper horizontal handle 63 and the side upright rod 61 can be flexibly adjusted according to the patient's usage habits. The locking pin 65 can be a component of existing products on the market [such as baby strollers].
[0025] like Figure 2 to Figure 4 As shown, in this embodiment, auxiliary grips 66 are symmetrically installed on both sides of the lower part of the upper horizontal handle 63, and one end of the auxiliary grips 66 facing away from the center of the upper horizontal handle 63 is fixed on the upper horizontal handle 63, and an enlarged round head is provided on the end of the auxiliary grips 66 facing the center of the upper horizontal handle 63. In this way, when walking, the patient holds both hands on the upper horizontal handle 63, and the outer sides of the thenars of both hands and the two thumbs respectively rest on the two auxiliary grips 66, so that the detachable walker 6 can be moved forward more conveniently, labor-savingly, and accurately.
[0026] like Figure 4 As shown, in this embodiment, a water cup holder 67 is provided on the upper horizontal handle 63, so that the patient can carry a water cup when doing walking exercises.
[0027] like Figure 2 to Figure 4As shown, in this embodiment, the lower end of the side upright rod 61 and the middle bottom of the crossbeam are both installed with a telescopic support rod 68. Such an arrangement enables the height of the entire detachable walker 6 to be flexibly adjusted according to the height of the user to meet diverse usage requirements.
[0028] like Figure 1 As shown, in this embodiment, a reinforcing diagonal rod 9 is arranged between the side wall of the vertical plug-in tube 7 and the chair frame 1. This arrangement improves the structural strength of the vertical plug-in tube 7, and it is safer and more reliable to use the detachable walker 6 to push the wheelchair. A storage rack is installed at the bottom of the wheelchair in the utility model to facilitate the placement of items.
