[0004] To achieve the above objective, the present invention provides a technical solution as follows: the angle adjustable children dining chair angle adjustable children dining chair may comprise a dining table, support legs and a barstool, wherein on the lower surface of the dining table is provided a chair connection support and the chair connection support is fixed on the barstool. To the side of the bottom of the barstool, support legs are provided. To the lower surface of the chair connection support, an assembly hole is provided and a universal ball pulley is provided in the assembly hole. The universal ball pulley may contact the upper surface of the barstool. Inside the chair connection support is provided a support hole where a positioning post is provided. At the top end of the positioning post is provided a vertical spring and the positioning post is connected to the lower surface of the dining table through the vertical spring. In the positioning post, an inclined sliding chute is provided and in the inclined sliding chute, a key is provided.

[0005] Furthermore, surface of the key is designed to be inclining corresponding to the inclined sliding chute.

[0006] Furthermore, the key is inserted into the chair connection support and its pressing end is provided outside the chair connection support.

[0007] Furthermore, the key is connected to the outside of the positioning post with a horizontal spring.

[0008] Furthermore, in the central part of the chair connection support is provided a supporting rod. The upper end of the supporting rod detachably contacts but is not connected to the lower surface of the dining table which allows rotation of the dining table.

[0009] Furthermore, outer surface of the lower end of the supporting rod is provided with thread, and the bottom of the supporting rod goes through the barstool.

[0010] Furthermore, the bottom of the supporting rod may be fixed on the barstool by screw connection.

[0011] Compared with existing technology, beneficial effects of the present invention are as follow:

(1) The present invention excises force with the key to the positioning post, which is located in the supporting hole. By the displacement between the positioning post and the supporting hole, the positioning post leaves hole on the barstool and is moved upwards, consequently, the dining chair can be free to rotate. When the key is pressed again and retrieves to the original position, the positioning post returns to the hole on the barstool under the effect of the spring, which fixes the rotating chair to the desired position. In this way, it is not necessary to move the chair however possible to adjust the dining chair for 360 degrees conveniently.

(2) In the present invention, four universal ball pulleys are evenly provided on the bottom side of the chair connection support and during rotation, the chair connection support slides against the barstool by the universal ball pulleys, which reduces frictional resistance during rotation, and is flexible and suitable for commercialization.
