Description of drawings:

Accompanying drawing 1 is the structural representation of the utility model;

Accompanying drawing 2 is the partial structural representation of the utility model.

Detailed ways:

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Fig. 1 and Fig. 2, the beach chair backrest repeated fatigue testing machine described in the utility model includes a test stand 11, and it also includes a fixing block 10 for fixing the beach chair, and the test stand 11 has multiple threaded holes at different positions, and the fixed block 10 is fixedly connected to the threaded holes; the test bench 11 is also provided with a column, and the top of the column is provided with a handwheel 1, and the handwheel 1 is connected with a screw rod arranged on the inside of the column through a gear. 2. The screw rod 2 is threadedly connected to the fixed platen 3, and the fixed platen 3 is connected to the cylinder 5. The output shaft of the cylinder 5 is equipped with a splint 8 for clamping the back of the beach chair, and the output shaft of the cylinder 5 is also equipped with a load Element 7, the column is equipped with an air pressure regulating device 13, a force display 14 and a control panel 12.

As a preferred embodiment, the cylinder 5 is hinged to the fixed platen 3, and an adjusting screw 6 for adjusting the angle of the cylinder 5 is arranged between the cylinder 5 and the fixed platen 3. By operating the adjusting screw 6, the cylinder can be adjusted The angle of 5 makes the cylinder 5 vertical to the backrest, which is very convenient to operate. Further, the fixed platen 3 is provided with a dial 4, so that the adjustment angle of the air cylinder 5 can be seen intuitively, which further facilitates the operation.
