[0040] The working principle of this utility model:

[0041] When it is necessary to test the position of the chair with different support legs, the first motor 801 is started, which drives the adjusting screw 802 to rotate. The adjusting screw 802 will drive the toothed plate 803 to move. During the movement, the toothed plate 803 will drive the adjusting gear 804 and the positioning part 7 to rotate synchronously. When the groove of the positioning part 7 reaches the position corresponding to the support leg of the chair, the first motor 801 is stopped, and the positioning part 7 stops rotating, thus completing the adjustment.

[0042] When it is necessary to test lounge chairs of different sizes, the second motor 1101 is started, which drives the drive screw 1102 to rotate. The drive screw 1102 drives the transmission rack 1103 to move. During the movement of the transmission rack 1103, the transmission gear 1104 and the control disk 1105 rotate synchronously. The control disk 1105 drives the push column 10 to move in the inner cavity of the extrusion hole 1106. The push column 10 drives the limit block 9 to move on the surface of the limit column 13. The limit block 9 drives the positioning box 6 and the positioning component 7 to move synchronously. When the positioning component 7 reaches the appropriate position, the second motor 1101 is stopped, and the positioning component 7 stops moving, thus completing the work.

[0043] In summary, this fatigue testing machine for lounge chairs, through the coordinated use of a receiving groove 4, a support plate 5, a positioning box 6, a positioning component 7, an adjusting device 8, a limiting block 9, a pushing column 10, and a driving device 11, solves the problem that existing lounge chair fatigue testing machines typically require users to manually adjust the four fixing devices on the top of the base according to the position of the four support legs of the lounge chair, which is time-consuming and labor-intensive, increasing the user's workload.
