It will be readily appreciated that the range of travel of the first driver 30 also corresponds to and controls the amplitude of rotation of the back frame 20.

In order to play a retaining effect on the back frame 20, the back frame 20 is prevented from being unstable under external force. As shown in fig. 3, the back frame 20 is provided with a ratchet 21, and the chair frame 10 is provided with a pawl 40. It will be readily appreciated that the pawl 40 and ratchet 21 are of a unitized construction and form an integral mechanism. When the pawl 40 is engaged to the ratchet 21, the back frame 20 is stopped, and reverse movement thereof is prevented.

In practice, based on the rotation characteristic of the back frame 20, when the ratchet 21 is provided, it is necessary to provide a circular arc surface on the back frame 20 and provide the ratchet 21 on the circumference thereof to adapt to the rotation of the back frame 20.

In some specific embodiments, as shown in fig. 3 and 6, the back frame 20 includes a main body for backing and a tray body separately used for setting the ratchet 21, the main body and the tray body are fixedly arranged on a rotating shaft for realizing the rotation of the back frame 20, the main body and the tray body realize synchronous rotation, and the ratchet 21 is meshed with the ratchet 21 on the tray body, that is, the whole back frame 20 realizes backstop.

Thus, when necessary, the third rotating shaft 120 can be detached from the mounting frame 11, so that the pawl 40 is separated from the ratchet 20, the stopping effect is further canceled, and the back frame 20 can be freely moved. For example, in the case where the second driver 50 is an air cylinder and the power is off, the air of the second driver 50 may be released to lose the function, and then the third rotation shaft 120 is detached from the mounting frame 11, so that the retaining effect of the pawl 40 and the ratchet 20 is lost, and the back frame 20 can freely move.

Further, as shown in fig. 7, the third rotation shaft 120 may be screwed to the mounting frame 11, and the threads are provided at both ends of the third rotation shaft 120.

The first driver 30 can be used to adjust the speed and push-pull force of the back frame 20, especially the cylinder is used to achieve the optimal opening, closing speed and push-pull force of the back frame 20, so as to reduce the impact caused by the too high speed of the back frame 20 during opening and closing. The elastic following of the pawl and the ratchet wheel is stable and reliable due to the spring reset quality. The utility model is convenient to maintain, and grease is filled into each gear in a specified maintenance period. The utility model selects the standard pneumatic actuator as the driver, has the advantages of price, stable performance and wide market application, and greatly reduces the cost of equipment.
