Thus, the tilting angle of the seat plate around the pivot can be implemented by manipulating the position of the slider.

Specifically, the support rod 122 is a telescopic rod, and is an air cylinder, an oil cylinder or an electric cylinder. Therefore, the position of the sliding block can be controlled by further changing the length of the stay bar, so that the seat plate can present a required angle.

In this example, the brace 122 is a gas spring.

Referring to fig. 7 and 8, an inner bracket c11 is also provided in the seat pan c1, and the turnover mechanism 12 further includes a top bracing assembly 124 provided between the front and rear portions of the seat pan 102 and mounted on the inner bracket c 11. Further improving the support effect provided by the seat plate.

The inner bracket c11 comprises an inclined strut c110 which is fixed at the front end of the cavity hopper c1 at one end and supported on the seat cover c3 at the other end; the bracing assembly 124 comprises a first part d1 arranged on the bracing c110, a second part d2 arranged on the seat plate 102, wherein the first part d1 and the second part d2 are connected in a universal rotation mode, and the bracing assembly is used for positioning the bracing c110 on a bracing plate c111 on a bottom plate of the seat cavity hopper c 1. In this case, the universal rotation adjustment is used to meet any angular change and always maintain an effective support.

In this example, a connecting bolt is provided on the brace c110, a ball head is formed at the upper end, a connecting head is provided at the corresponding position of the seat plate 102, and the connecting head and the ball head are connected in a wrapping type rotation manner, that is, the first part d1 is a ball head piece; the second part d2 is a ball socket piece.

The backrest 20 includes a lower leaning rod 200 whose lower end portion is butted against the sliding base 101, and an upper leaning rod 201 which rotates with the lower leaning rod 200 and is movably adjusted along the length direction of the lower leaning rod 200, and the cushion 21 is mounted on the upper leaning rod 201.

A notch is formed in the rear portion of the seat plate 102, the lower leaning rod 200 is connected in the slide 101 through a connecting shaft from the lower end portion, and the upper end portion of the lower leaning rod 200 penetrates out of the notch and is located above the seat cushion 21.

The upper leaning rod 201 includes a first rod g1 rotating and locking with the upper portion of the lower leaning rod 200 around the horizontal direction, a second rod g2 movably arranged on the first rod g1 along the length direction of the first rod g1, and a locking portion g3 locking the first rod g1 and the second rod g2 relatively. This provides two benefits: 1. the inclination angle of the backrest can be adjusted; 2. the extension height adjustment of the backrest can be performed. That is, whether it is angular or high, its ultimate purpose is to meet the use needs of the physician at work or rest.

In this example, the back pad 21 is provided on the upper portion of the second rod g 2. In this way, the adjustment of the position of the backrest cushion 21 is performed by the adjustment of the second rod g2, thereby providing comfortable support of the backrest portion 2 at a proper position and angle.

In addition, in this example, it needs to be further explained that: when the upper leaning rod 201 and the lower leaning rod 200 rotate relatively and are folded, the backrest cushion 21 and the seat cushion 11 are relatively close to each other and are arranged in a vertically attached mode. Therefore, the folding chair can be folded and is convenient to transport.
