Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "vertical", "upper", "lower", "horizontal", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; either directly or indirectly through intervening media, or through the communication between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a practical multifunctional seat, include main part 2 and be located the back support 13 that 2 tops of main part are close to one end, install fixed frame 4 on the lateral wall of back support 13, there is adjusting bolt 5 at the middle part of fixed frame 4 through threaded connection, fly leaf 7 is installed to adjusting bolt 5's end, and be provided with bearing 10 between adjusting bolt 5's end and the fly leaf 7, the outer lane of bearing 10 and the inner wall fixed connection of fly leaf 7, bearing 10 has been set up, can make fly leaf 7 not follow adjusting bolt 5 and rotate, the inner circle of fly leaf 7 and adjusting bolt 5's terminal fixed connection, the cambered surface has been seted up to one side that fly leaf 7 and main part 2 are close to, install sponge layer 8 in the cambered surface of fly leaf 7, and fixed frame 4's inner wall is provided with the inside guide.

In this embodiment, preferably, the outer wall of the adjusting bolt 5 is screwed with a limit nut 9.

In this embodiment, preferably, the movable plate 7 and the sponge layer 8 have guide holes 12 corresponding to the guide posts 11.
