Detailed ways

The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

As shown in Figures 1 and 2, a large stroke and high load tilt angle adjustment device includes a flat plate 5, a cylindrical linear guide 6, a lead screw 11, a lead screw fixing seat 12, a support arm 1 and a lift arm 2, wherein, The plate 5 includes an upper plate and a lower plate arranged up and down, the inner side of the lower plate is connected with the inner side of the upper plate through two support arms 1, and the upper end of the support arm 1 is connected with the upper plate through a pin, so that the upper plate can wrap around the support arm 1. The pin at the upper end rotates; mounting holes are arranged on the flat plate 5 for installing other related components; a cylindrical linear guide 6 is installed on the outer flat surface of the lower flat plate, and two sliding blocks 7 are arranged on the cylindrical linear guide 6 , so that the slider 7 can slide left and right along the cylindrical linear guide rail 6; the slider 7 is installed with a screw fixing seat 12, and the screw 11 with the handwheel 14 at the end passes through the two screw fixing seats 12, and passes through the two screw fixing seats 12. When the handwheel 14 drives the lead screw 11 to rotate, it drives the two lead screw fixing seats 12 matched with the lead screw 11 to move in the direction of approaching or separating from each other; The shafts are connected, the other end of the lifting arm 2 is installed on the outer side of the upper plate through the shaft seat 3, and the screw fixing seat 12 moves left and right to drive the supporting height of the lifting arm to change, so that the upper plate rotates around the upper end of the lifting arm 2.
