Abstract
The utility model discloses sofa ironware capable of adaptively adjusting a backrest by multiple angles. A stretching mechanism (3) is arranged on a bottom rack (5) in a scalable manner and is connected with a square shaft (9); the square shaft (9) is rotatably arranged on the bottom rack (5); a hand shank (8) is arranged at the side surface of the square shaft (9); a balance adjuster (1) is arranged in the middle of the front end of the bottom rack (5) and comprises a cross bar (11), a support rod (12), a dental plate (13), a round shaft (14), a connecting rod (15) and a square shaft sleeve (16); one end of a balancing rod (2) is rotatably connected with the round shaft (14); and the other end of the balancing rod (2) is fixed together with a handrail frame (7) through a pin hole. The sofa ironware has the advantages of being simple in structure, and time-saving when stretching, and can utilize the weight of a user to adaptively adjust the angle of the backrest, so as to achieve the comfortable multi-angle adaptive adjustment of the backrest so as to be adaptive to a sitting posture and a lying posture.
Description
[technical field]
The utility model includes the sofa that stretches parts, the chair form bed of backrest and handrail etc. is arranged; The parts, part or the accessory that relate to above-mentioned furniture.
[background technology]
Leisure Sofa can integral body shake when reclaiming, and can regulate seat and back angle after stretching, this regulatory function realizes by the sofa ironware, the sofa ironware that can regulate seat and backrest angle includes balance regulator, balancing pole, underframe, handle and square shaft, handle is loaded on the square shaft end, square shaft is loaded on the underframe rotationally, the adjusting ironware is arranged on balance regulator and the balancing pole, be loaded on the underframe, adjusting angle with square shaft interlock control sofa backrest, it is many that the sofa of prior art is regulated ironware rivet joint, complex structure, there is not slide rail, when stretching, cushion and backrest too require great effort, angle is single, can not regulate adaptively rational position, this is its shortcoming.
[summary of the invention]
Shortcoming for prior art, the purpose of this utility model is to provide that a kind of ironware rivet joint is few, simple in structure, laborsaving when cushion and backrest stretch, can carry out multi-angle and regulate, but can utilize user's own wt self adaptation adjusting angle of backrest, to reach the sofa ironware of the comfortable multi-angle self adaptation of sitting posture and lying posture adjusting angle of backrest.
The technical scheme that its technical problem that solves the utility model adopts is: but provide a kind of multi-angle self adaptation to regulate the sofa ironware of backrest, include underframe, extension means, handle and square shaft, the extension means telescopically is loaded on the underframe and is connected with square shaft, square shaft is loaded on the underframe rotationally, handle is loaded on the square shaft side, it is characterized in that: also include balance regulator and balancing pole, described balance regulator is installed in underframe front end middle part, comprise cross bar, support bar, tooth plate, circular shaft, connecting rod and square shaft cover, cross bar is fixed on the underframe, support bar stands on the cross bar middle part, tooth plate and support bar engagement also are set on the circular shaft rotationally, connecting rod is connected affixed and is connected with circular shaft rotationally with square shaft, the square shaft cover is set on the square shaft and rotates with square shaft; Described balancing pole one end is connected with circular shaft rotationally, and the other end is fixed by its pin hole and handrail frame.
Tooth plate shape in the balance regulator can such as the willow leaf tooth, mesh with support bar with convenient, so that balance regulator reaches the needed by human body best angle by total balance of the body and lumbar support after stretching.
Balancing pole can keep handrail balance and fastness.
Further, can also comprise cushion slide rail and backrest slide rail,
The both sides that cushion slide rail can be arranged on balancing pole are fixed on the handrail frame, the depth that the lumbar support by human body just can mobile adjusting sitting posture.
The backrest slide rail can be arranged on the posterior medial face of handrail frame, installs with cushion to be connected, and cushion slide rail namely can move adjusting angle of backrest by the human body waist synchronously.
The beneficial effects of the utility model are: but simple in structure, more laborsaving when stretching, can utilize user's own wt self adaptation adjusting angle of backrest, regulate backrest to reach the comfortable multi-angle self adaptation of sitting posture and lying posture.
