DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention is a ball chair, and more particularly a ball chair having a reinforcing structure. [Prior Art] As shown in the fifth and sixth figures, the existing ball chair structure includes a seat (5G), and the seat (5〇) is formed with a top surface (5 1 ) at the seating position, and A back (5 4 ) is disposed on the rear side of the top surface, and a through hole is formed in the center of the top surface (5 1 ). The through hole is provided with a ball body (6 (two)), and the top surface is different from the seat back The other side of the (54) is respectively spaced apart from the protruding block two coupling block (56), and the two coupling blocks (56) can respectively fix the rod (7〇), and the positioning rod (7〇) is not in the middle section and the seat is 5〇) The top surface...) is placed above the top surface and adjacent to the sphere ^6 〇) for the user to ride above the sphere (6 ◦) = the height of the (four) body (6 〇). Reduce the spheroid () The perforation (1)) is detached from the front side and both sides. In addition, three or more branches are formed on the periphery of the seat (2) at the same distance. One end of each branch (") is dragged with a wheel (5: to facilitate the movement of the ball chair.) Please refer to the special reference. As shown in the sixth figure, the ball structure design, mainly erected, μ I 4 4) people... ergonomic curved vertical plate, and right social combination end (542), the binding end: , with - knot, between the ball chair seat (50) - there is no auxiliary fixing device - directly, the sub-5 hai binding end (5 4 2 ) is 1292308 - long straight segment type, If the inner diameter of the seat is too small and the outer diameter of the seat back is too large, the seat and the chair will not be assembled (this is a defective product), and if the inner diameter of the seat is too large and the outer diameter of the seat is too small, When the user rides on the ball chair and relies on (4), the difference between the inner and outer diameters of the seat and the back is too large and the j is too large. In the absence of the auxiliary reinforcement design, it is easy to connect to the θ end (542 ) cracks occur at the junction with the seat (5〇), resulting in a shortened service life of the ball chair and even danger in use. [Summary of the Invention] In addition to the imperfection of the design of the existing ball chair on the back structure of the chair, the inventor particularly improved the structure of the chair back of the ball chair to alleviate the problem of the above-mentioned existing ball chair. The main purpose of the month's ball chair is to provide a kind of change in the joint shape between the back of the chair and the i, to increase the strength of the back of the chair while flooding and fixing, making the use of the ball chair more durable and safe. 4. The purpose of the present invention is to provide a ball chair according to the user's needs, the ball, and the inclination, and thereby the ball chair of the present invention can be properly clamped. The ball chair of the present invention includes a ball. a chair comprising: a seat, a latching portion on a rear side of the top surface of the seat; a ball coupled to the seat; and 1292308. Preferably, the ball chair includes at least one It is possible to wear a ball chair seat and a seat back, and preferably, the ball seat back is placed in one or two sets. The angle of the seat back conforms to the angle required by the user. Preferably, the ball chair back is further provided The height adjustment device is provided to provide the seat back with the height required by the user. The present invention utilizes a seat back stop gauge, and the abutment portion of the k seat is provided with two:: the abutment portion can limit the chair Tilting back to the rear to reach the desired back angle of the user's 'to make the ball chair durable'. [Embodiment] Please refer to the first and second figures, the ball chair of the present invention mainly includes a seat ( 10) 'A seat back (2 〇)' attached to the side of the seat (1〇) and a ball (4 0) placed on the seat (1〇). (10), a bedding surface (u) is formed at the seating position, and a receiving hole (丄2) is formed in the center of the top surface (1 1 ), and the receiving hole (12) is provided in the foregoing Sphere (4〇). Seat (ι 〇) one; has the aforementioned seat back (2G), the top of the seat (1Q) (1 ι) circumference: at the back of the seat (20), there are two joint blocks (1 3 A positioning rod (14) for holding a ball (4 〇) may be respectively disposed on the coupling block (i 3 ). The bottom surface of the seat (10) is provided with three or more support portions (15) = for supporting the seat (10) for good positioning. Preferably, the bottom surface of the support portion (15) is respectively provided for movement. The seat (丄〇6) of the seat (丄〇6) The seat (! 0) has a latching portion 1292308 extending from the side with the seat back (20). The top surface is provided with a coupling groove (1 7 1 ). , a slot (172), the top of the cassette (1 7) (1 7 3 ).
