In the figure: 1. the chair comprises a headrest, 2 movable support legs, 3 a backrest, 4 a seat plate, 5 fixed support legs, 6 fastening screws, 7 horizontal embedding sleeves, 8 bearings, 9 vertical embedding sleeves, 10 rotating shafts, 11 lock pins, 12 springs and 13 sealing covers.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solutions claimed in the claims of the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments.

Fig. 1 and 2 show: the back cushion 1 is combined with the backrest 3 through a fastening screw 6, and the lower parts of two sides are provided with hemispherical grooves; grooves are formed in two sides of the backrest 3 and used for containing the movable supporting legs 2 in a vertical state, a hemispherical groove is formed in the upper end of each groove, and a 45-degree inclined plane is formed in the lower end of the backrest 3; the rear end of the seat board 4 is set to be a 45-degree inclined plane, the middle part of the 45-degree inclined plane is provided with a rotating shaft 10 which is combined with a bearing 8 arranged in the 45-degree inclined plane at the lower end of the backrest 3 and can rotate, so that the conversion between the vertical state and the horizontal state of the backrest 3 is realized, and the lower end of the seat board 4 is fixedly connected with the symmetrically arranged fixed support legs 5; a locking mechanism consisting of a lock pin 11, a spring 12 and a sealing cover 13 is arranged in the seat plate 4, and the lock pin 11 can be respectively combined with a vertical embedded sleeve 9 and a horizontal embedded sleeve 7 which are arranged in a 45-degree inclined plane at the lower end of the backrest 3 by pulling a flexible pull ring arranged at the end part of the lock pin 11, so that the locking of the backrest 3 in a vertical state and a horizontal state is realized; the upper ends of the movable support legs 2 are arranged to be spherical, and can rotate in a complete ball groove formed by the back cushion 1 and the backrest 3, so that the storage in a vertical state and the support in a horizontal state are realized.

The lower parts of two sides of the back cushion 1 are provided with hemispherical grooves which are combined with the hemispherical grooves arranged at the upper ends of the grooves of two sides of the back 3 to form a complete spherical groove, so that the movable support legs 2 can rotate around the spherical structure arranged at the upper parts.

The two sides of the backrest 3 are provided with grooves, and the movable support legs 2 can be accommodated in a vertical state.

The lower end of the backrest 3 and the rear end of the seat plate 4 are both arranged to be 45-degree inclined planes, and a rotary mechanism is formed by the bearings 8 and the rotating shaft 10 which are respectively arranged, so that the backrest 3 can be rapidly switched from a vertical state to a horizontal state.

The seat plate 4 is provided with a locking mechanism consisting of a lock pin 11, a spring 12 and a sealing cover 13, and the lock pin 11 can be respectively combined with a vertical embedded sleeve 9 and a horizontal embedded sleeve 7 which are arranged in a 45-degree inclined plane at the lower end of the backrest 3 by pulling a flexible pull ring arranged at the end part of the lock pin 11, so that the locking of the backrest 3 in a vertical state and a horizontal state is realized.

The utility model is implemented specifically as follows:

when the backrest is normally used, the backrest 3 is in a vertical state, the lock pin 11 is combined with the vertical embedding sleeve 9 under the action of the spring 12 to keep locking, and meanwhile, the movable support legs 2 are accommodated in the grooves on two sides of the backrest 3; when the state needs to be switched, the flexible pull ring at the end part of the lock pin 11 is pulled to enable the lock pin 11 to exit the vertical embedding sleeve 9 to remove vertical locking, the backrest 3 is rotated to be in a horizontal state, the lock pin 11 is loosened to enable the lock pin to be matched with the horizontal locking sleeve 7 to achieve horizontal locking, and meanwhile, the movable support leg 2 accommodated in the groove of the backrest 3 is opened to enable the movable support leg 2 to be kept in a supporting state, so that the vertical state and the horizontal state are rapidly switched.

The utility model is very flexible and convenient when being used for switching between the vertical state and the horizontal state. Before and after the conversion, the backrest can be kept locked under the action of the locking mechanism, and the backrest is safe and reliable, so that more seats or rest and lie positions are provided while the occupied space is saved.
