Description

Technical field

The present invention relates to dining chair, especially to an angle adjustable children dining chair.

Background technology

Dining chair is used specially for having meals. It is an indispensable piece of furniture during daily life, and classified by material a dining chair is made from, there are solid wood one, steel one, marble one, and marble dining table etc. Children dining chair is designed for children to have meals, which will foster children good habit of sitting and dining, avoid the trouble of following children everywhere to have them eat, furthermore, when children are sitting in a suitable chair, they are unlikely to be slanting, and their hands can be free to hold the dining accessories, which is conducive to improve coordination of hands, eyes and brain. Currently it is not possible to adjust angle of existing dining chairs but to move manually, which is not user friendly.

Detailed description of the invention

In accordance with the defects and problems shown in the background technology, the present invention provides an angle adjustable children dining chair to address the problems appeared in the prior art.
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.
Furthermore, surface of the key is designed to be inclining corresponding to the inclined sliding chute.
Furthermore, the key is inserted into the chair connection support and its pressing end is provided outside the chair connection support.
Furthermore, the key is connected to the outside of the positioning post with a horizontal spring.
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.
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.
Furthermore, the bottom of the supporting rod may be fixed on the barstool by screw connection.
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.

Description of the drawings

Fig. 1 is the structural view of the angle adjustable children dining chair.
Fig. 2 is a partial enlarged view of the angle adjustable children dining chair.

The technical scheme of the present invention will be further described in detail in combination with accompanying drawings and specific embodiments.
Embodiment 1: with accordance of the Fig. 1 to Fig. 2, the angle adjustable children dining chair angle adjustable children dining chair may comprise a dining table 1, support legs 2 and a barstool 3, wherein on the lower surface of the dining table 1 is provided a chair connection support 4 and the chair connection support 4 is fixed on the barstool 3. To the side of the bottom of the barstool 3, support legs 2 are provided to ensure the stability of the entire assembly and facilitate usage. To the lower surface of the chair connection support 4, an assembly hole is provided and a universal ball pulley 8 is provided in the assembly hole. The universal ball pulley 8 may contact the upper surface of the barstool 3 to ease rotation. Inside the chair connection support 4 is provided a support hole where a positioning post 6 is provided. At the top end of the positioning post 6 is provided a vertical spring and the positioning post 6 is connected to the lower surface of the dining table 1 through the vertical spring to facilitate rotation. In the positioning post 6 is provided with an inclined sliding chute, wherein a key 5 with a corresponding inclined plane is provided in the inclined sliding chute however top side of the key 5 is provided outside the chair connection support 4.
