Description

a massage chair

technical field

The invention relates to a massage chair.

Background technique

There are many kinds of massage chairs at present, but some massage chairs with simple structure have single function, such as backrest and tripod, which cannot be rotated, and the seat elasticity is not good, so good comfort cannot be provided. However, if the current massage chairs are to satisfy these functions, they need a very complicated structure, which makes the massage chairs expensive to manufacture.

Contents of the invention

The present invention aims to solve the above-mentioned shortcomings of the prior art, and provides a massage chair, which has a compact and reasonable structural design, realizes the linkage rotation of the backrest and the tripod, has good elasticity of the seat frame, and is safe to use.

The technical scheme adopted by the present invention to solve its technical problems: this massage chair includes a support seat, a seat frame, a foot frame and a backrest, the support seat is supported on the bottom of the seat frame, and the foot frame and the backrest are respectively rotatably connected to the front and rear ends of the seat frame. The lower end is fixed with a rear turret, the two sides of the upper end of the rear turret are rotatably connected to the rear end of the seat frame, the lower end of the rear turret is connected with a gas spring, the gas spring is connected with a brake line, and the gas spring is installed on the seat frame; The front end is equipped with a front turret to push the tripod to rotate. The front turret includes an inner strut and an outer strut. The upper ends of the inner strut and the outer strut are fixed together and connected to the seat frame in rotation. The support wheel on the inner side of the tripod, the outer end of the inner support rod is connected to the connecting rod, and the rear end of the connecting rod is connected to the lower end of the rear turret; the supporting seat is provided with a lifting pneumatic rod, and the top of the lifting pneumatic rod is connected to There is a pneumatic rod fixing plate, and the seat frame fixing plate is installed on the seat frame. The rear end of the pneumatic rod fixing plate is fixed on the lifting pneumatic rod, and the middle rotation of the pneumatic rod fixing plate is connected to the rear end of the seat frame fixing plate. There is a through groove at the front end of the seat frame, and a screw rod is fixed on the fixing plate of the seat frame. The screw rod passes through the through groove, and a compression spring is set on the screw rod. Compression spring lock nut; the front end of the connecting rod is fixed with a positioning sleeve baffle, the seat frame positioning sleeve is fixed on the seat frame positioning sleeve, and the seat frame positioning sleeve is pierced with a push rod. A limit portion is provided at the lower end of the rod, and a spring that is sheathed outside the ejector rod is connected between the limit portion and the positioning sleeve of the seat frame.

The structure design of the above-mentioned massage chair is relatively simple, but its function is powerful. Both the backrest and the tripod can be rotated, the seat frame has good elasticity, and it is equipped with safety measures. The backrest and the tripod are linked by a connecting rod, and the backrest is connected with a gas spring to control the positioning, while the seat frame adopts a buffer device. Through the cooperation of the lever and the pressure spring, the control seat frame has good elasticity, and avoids overloading the seat When the chair rests, a safety protection limit device is installed under the seat frame. After accidents such as compression spring failure, it can also play a positioning role to ensure safe use, and the positioning sleeve baffle on the limit device is installed on the connecting rod. , Play a good elastic role in protection.

In order to further improve, a rotating positioning baffle is installed on the lifting pneumatic rod, and a limiting part extending outward is arranged on the rotating positioning baffle, and a positioning rod corresponding to the position of the limiting part is fixed on the fixing plate of the pneumatic rod. Since there are wires connected to the massage chair, the rotating positioning baffle prevents the wire from being entangled by the rotation of the seat frame, prevents the wire from being broken, and controls the rotation of the massage chair within a preset angle, effectively preventing cables, wires and other components in the massage chair Wrapped on the bracket to ensure the stability, reliability and durability of the massage chair.

The beneficial effects of the present invention are: the structural design of the present invention is very ingenious, the entire angle adjustment range of the seat is large, and different angles can be replaced, and the new massage chair linkage and cushioning technology can improve the use stability, use comfort and application range, so that The user uses it in the most comfortable position. The utility model has the advantages of convenient rotation, good seat spring, safety and reliability, and is conducive to wide popularization.
