Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

As shown in fig. 1 and 5, a chair with an adjustable backrest inclination angle comprises a chair frame and a cushion 9, wherein the cushion 9 is sleeved on the chair frame. The chair frame comprises a backrest support 1, an armrest support 2, a leg support 3, a rotating mechanism 4, a leg 5, a transverse support 7 and a longitudinal support 8. The two handrail supports 2 are horizontally arranged in parallel, one supporting leg 5 is fixedly connected below two ends of each handrail support 2 respectively, the backrest support 1 is connected at the same end of the two handrail supports 2 through a rotating mechanism 4 in a rotating mode, the two supporting legs 5 below the other ends of the two handrail supports 2 are connected with the leg supports 3 through a rotating mechanism 4 in a rotating mode, a transverse support 7 is fixedly connected between every two supporting legs 5, a longitudinal support 8 is detachably connected between the two transverse supports 7, and the longitudinal supports 8 are arranged along the length direction of the handrail supports 2.

Specifically, as shown in fig. 2, the rotation mechanism 4 includes a fixed member 401, a first pin 402, a torsion spring 403, a stopper 404, a second pin 405, a spacer 406, and a rotation member 407. The fixing member 401 is provided with a cavity, and the torsion spring 403, the blocking member 404, the spacer 406, and the rotating member 407 are all disposed in the cavity. The first pin shaft 402 and the second pin shaft 405 are sleeved through the cavity and connected to the fixing piece 401, and the torsion spring 403 is sleeved on the first pin shaft 402. The blocking member 401 is rotatably coupled to the first pin 402 and is coupled to one end of the torsion spring 403.

The gasket 406 is sleeved and connected on the second pin shaft 405 in a rotating way, two sides of the gasket 406 are respectively provided with a rotating piece 407, the rotating piece 407 is sleeved and connected with the second pin shaft 405 in a rotating way, the rotating piece 407 is fixedly connected with the leg support 3 or the backrest support 1, and the rotating piece 407 and the gasket 406 can be clamped with the blocking piece 404 in a discontinuous way under the action of the torsion spring 403.

As shown in fig. 3-4, the outline of the spacer 406 is two concentric circular arcs with different diameters, the outline of the rotating member 407 is two concentric circular arcs with different diameters, and a plurality of tooth-shaped protrusions are uniformly arranged on the circular arcs with large diameters along the circumference.

The extreme positions of the leg supports 3 are horizontal and vertical. When the leg support 3 rotates around the second pin shaft 405 from the vertical state to the horizontal state, the leg support 3 pushes the gasket 406 to rotate around the second pin shaft 405, so that the large-diameter circular arc section of the gasket 406 abuts against the blocking member 404, the blocking member 404 compresses the torsion spring 403, meanwhile, the distance between the tooth-shaped protrusion of the rotating member 407 and the blocking member 404 is increased and separated from the blocking member 404, and the leg support 3 drives the rotating member 407 to rotate together to the horizontal state. Then, the leg support 3 is pressed down, the leg support 3 pushes the spacer 3 downward, the large-diameter circular arc section of the spacer 3 is separated from the blocking member 404, the blocking member 404 is sprung up and is clamped between the two tooth-shaped protrusions of the rotating member 407 under the action of the torsion spring 403, and the leg support 3 is stopped. To continue to adjust the leg support 3 downward, the leg support 3 is first rotated slightly upward so that the large diameter circular arc section of the spacer 3 abuts the stopper 404, and then the leg support 3 is rotated downward until the leg support pushes the spacer 3 away, the tooth-shaped projections of the rotating member 407 re-catch the stopper 404, and the leg support 3 is stopped. The backrest support 1 is adjusted in the same way as the leg support 3.

The bottom end of the supporting leg 5 is sleeved with a foot pad 6, the foot pad 6 is a horseshoe-shaped plastic product, and friction noise between the supporting leg 5 and the ground is reduced.

The present utility model is not limited to the above-mentioned embodiments, and any person skilled in the art, based on the technical solution of the present utility model and the inventive concept thereof, can be replaced or changed within the scope of the present utility model.
