[0047] The slider seat 2 7 of the middle chair back test assembly cooperates with the slide rail 1 4 and the slide rail 2 6 so that the chair back test assembly as a whole can be vertically lifted and lowered along the slide rail 1 4 and the slide rail 2 6 .
[0048] The webbing seat is connected to the lifting wheel of the frame part through the webbing and the steering wheel. Turning the lifting wheel can make the middle seat back test assembly rise and fall along the sliding column as a whole. The lifting and falling is controlled by the lifting wheel, which saves time and effort. The cylinder angle adjustment plate can adjust the angle of the cylinder. After loosening the fixing screw of the cylinder angle seat, the cylinder can rotate to a certain extent. Thus adjusting the angle of the cylinder.
[0049] In summary, with the help of the above technical solution of the utility model, a slide rail group is installed on the seat test module. When the seat of a sofa or a chair has a certain tilt angle, when the seat test acts on the test surface, the seat test module can better fit the test surface; loosen the telescopic arm fixing handle, the telescopic arm can be adjusted forward and backward, so that the seat test module reaches the test position, and then fix the telescopic arm fixing handle; loosen the left and right fixed handles of the seat, and the seat test module can move left and right along the seat and move the slide rails left and right to adjust to the required position; a slide rail group is installed on the seat test module. When the seat of a sofa or a chair has a certain tilt angle, when the seat test acts on the test surface, the seat test module can better fit the test surface; the cylinder angle adjustment plate can adjust the angle of the cylinder, and the webbing seat is connected to the lifting and lowering wheel of the frame part through the webbing and the steering wheel. Turning the lifting and lowering wheel can make the backrest test as a whole rise and fall along the sliding column. The lifting and lowering is controlled by the lifting and lowering wheel, which saves time and effort; improves the efficiency of the test, and is easy to adjust, so that different positions can be tested conveniently.
[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
