Detailed ways

As shown in Fig. 1, Fig. 2, and Fig. 3, the lifting mobile nursing wheelchair car, the wheelchair lower bracket 10 is composed of two first horizontal bars 10-1 on the left and right and four columns vertically installed on the first horizontal bar 10-1. 10-2 composition, the upper bracket 15 of the vehicle body is installed on the upper ends of the two columns of the wheelchair lower bracket 10, and the wheelchair lower bracket 10 is installed on the bearing sleeve of the rotating shaft of the walking wheel 8 through the two rear columns 10-2′ located at the rear side , the guide wheels 12 are installed at the lower ends of the two front columns 10-2 in the forward direction, and there is a scissor lift mechanism 9, and its two active scissor levers 9-1 are respectively hinged on the two sliding sleeves 9-2 , two sliding sleeves 9-2 are respectively installed on the left and right two first crossbars 10-1. As shown in Figure 2, the two ends of the second cross bar 10-1' are installed on the front and rear columns respectively, and are parallel to the bracket 15 on the vehicle body, and the other end of the active scissor bar 9-1 is hinged on the sliding sleeve 9-5, The sliding sleeve 9-5 is installed on the second cross bar 10-1′, and the screw mechanism 13 is composed of a leading screw 13-3 and a nut 13-2. The extended end of the leading screw 13-3 is connected to the At the middle position of a connecting rod 9-6, the two ends of the first connecting rod 9-6 are respectively connected on the two sliding sleeves 9-2, and the handle 13-1 is installed on the nut 13-2; One end of the guide rail 14-2 is respectively hinged on the two tail ends of the bracket 18 on the vehicle body, and the back side of the wheelchair back 2 is respectively equipped with two sets of second pulleys 6' which are in sliding contact with the two second guide rails 14-2. Two groups of first pulleys 6 are installed below the surface 5, and the left and right two first guide rails 14-1 are installed on the vehicle body upper support 15 respectively, and the two groups of first pulleys 6 are in sliding contact with the left and right two first guide rails 14-1 respectively.

As shown in Fig. 1, Fig. 2 and Fig. 3, the seat surface locking mechanism 7 is a four-bar linkage mechanism, wherein the manual bellcrank 7-1 is hinged with the second connecting rod 7-2, and the second connecting rod 7-2 is connected with the second connecting rod 7-2. The third connecting rod 7-3 that is hinged on the first connecting rod 9-6 is hinged, and the other end of the bellcrank 7-4 with the buckle pin at the tail end is connected with the third connecting rod 7-3 and is hinged on the same hinge shaft .
