[0029] To make the purpose, technical scheme and advantages of the embodiments of the present disclosure clearer, the technical scheme of the embodiments of the present disclosure will be described clearly and completely below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without any inventive effort fall within the protection scope of the present disclosure.

[0030] Please refer to Figures 1-4 A multi-directional controllable massage office chair, comprising a base 1 and a backrest assembly 2 rotatably connected to the base 1, a connecting mechanism 3 is arranged between the base 1 and the backrest assembly 2, the connecting mechanism 3 comprises first support rods 31 rotatably connected to both sides of the base 1, two second support rods 32 are fixedly connected to both sides of the bottom of the backrest assembly 2, both the first support rods 31 and the second support rods 32 are rotatably connected to a seat cushion 33, and a reset assembly is further arranged on the base 1. The backrest assembly 2 comprises a rotating part rotatably connected to the base 1 and a backrest (not shown in the figure), and the rotating part and the backrest are fixedly connected; the base 1 can be moved in cooperation with a connecting rod and a pulley block, which is a common technical means for a person skilled in the art and will not be described here.

[0031] Further, the reset assembly comprises two elastic sheets 41, one end of the elastic sheet 41 is fixedly connected to the base 1, the other end is arranged between the base 1 and the chair back assembly 2 and abuts against the slide rod 42 on the chair back assembly 2. During rotation of the chair back assembly 2 around the base 1, the slide rod 42 abuts and slidably connects to the elastic sheet 41, so that the elastic sheet 41 is bent, thereby providing a force for resetting the chair back assembly 2, and the bending of the elastic sheet 41 enables the user to slowly lean back more comfortably rather than quickly, thereby improving the use experience. The elastic sheet 41 is a glass fiber elastic sheet 41, which is a sheet-shaped material made of glass fiber as the main raw material and has high strength and good elasticity.

[0032] Further, the connecting mechanism 3 further comprises a limiter for limiting the rotation range of the chair back assembly 2. The limiter avoids excessive rotation of the chair back assembly 2 and damages the elastic sheet 41.

[0033] Further, the limiter comprises a rotating shaft 51 fixedly arranged on the chair back assembly 2, the rotating shaft 51 is rotatably connected to the base 1, a first limiting plate 52 is fixedly arranged on the rotating shaft 51, and a second limiting plate 53 corresponding in position to the first limiting plate 52 is fixedly arranged on the base 1. The chair back assembly 2 rotates around the rotating shaft 51 relative to the base 1, the rotating shaft 51 rotates to drive the first limiting plate 52 to rotate, and when the first limiting plate 52 rotates to abut against the second limiting plate 53, the chair back assembly 2 stops rotating.

[0034] Further, the connecting mechanism 3 further comprises a locker 6 for locking the chair back assembly 2. During rotation of the chair back assembly 2, the locker 6 fixes the rotation angle of the chair back, thereby facilitating use.

[0035] Further, the locker 6 comprises an adjusting rod 61 slidably arranged on the base 1, an adjusting plate 62 is fixedly connected to the end of the adjusting rod 61, the adjusting plate 62 is slidably connected to the rotating shaft 51, a plurality of first locking pieces 63 are annularly arranged on the rotating shaft 51, a locking groove 64 is formed between adjacent first locking pieces 63, a plurality of second locking pieces 65 corresponding to the locking grooves 64 are fixedly arranged on the adjusting plate 62, and a compression spring 66 is arranged between the adjusting plate 62 and the base 1. The compression spring 66 is inserted into the outside of the adjusting rod 61.

[0036] Pulling the adjusting rod 61 compresses the compression spring 66, so that the second locking pieces 65 are separated from the locking grooves 64, and the chair back assembly 2 can start to rotate. When the chair back assembly 2 is rotated to a suitable position, the adjusting rod 61 is released, the compression spring 66 drives the second locking pieces 65 to insert into the locking grooves 64 through the adjusting plate 62, thereby fixing the current position of the chair back assembly 2.

[0037] Further, the first locking piece 63 and the second locking piece 65 are arranged in an arc shape on the side close to each other, thereby facilitating the insertion of the second locking piece 65 into the first locking piece 63. It can be understood that the side close to each other of the first locking piece 63 and the second locking piece 65 can be arranged in a contraction, further facilitating the insertion of the second locking piece 65 into the first locking piece 63.

[0038] The above only describes certain exemplary embodiments of the present application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the above drawings and descriptions are illustrative in nature and should not be understood as limiting the scope of protection of the present application.
