[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Refer to the instruction manual Figure 1-5 , including an expandable chair back 1, a seat surface 2, a high trapezoidal chair leg 3, a connecting block 4, a low trapezoidal chair leg 6 and a connecting plate 8. The expandable chair back 1 includes an upper plate 1-3, a lower plate 1-4 and an expandable connecting rod 7. The expandable connecting rod 7 is connected to the upper plate 1-3 and the lower plate 1-4 by screws through a hinge 5. The upper plate 1-3 and the lower plate 1-4 are hinged by the expandable connecting rod 7. The lower end of the lower plate 1-4 is provided with a chair back connecting rod 1-5; the seat surface 2 is in the shape of a rectangular plate, and disassembly holes 2-1 are provided at both ends of the seat surface 2. The disassembly holes 2-1 are hinged to the high trapezoidal chair leg 3 through hinges 5. One end of the seat surface 2 is provided with a device positioning hole 2-2, and the device positioning hole 2-2 is screwed to the connecting block 4; a hinge 5 is provided in the middle of the high trapezoidal chair leg 3, and the hinge 5 corresponds to the disassembly hole 2-1. The hinge 5 It is installed on both sides of the seat surface 2 by bolts, and a connecting plate 8 is provided at the bottom of the high trapezoidal chair leg 3; the expandable chair back 1 is connected to the seat surface 2 by a connecting block 4; since the upper plate 1-3 and the lower plate 1-4 are both arranged by a hinge connection, the upper plate 1-3 and the lower plate 1-4 can be unfolded to a flat state, and the connecting block 4 and the seat back connecting rod 1-5 are switched between a fixed state and a rotating state by tightening and loosening the screws, so that the seat surface 2 and the expandable chair back 1 are deformed, so that the seat surface 2 and the expandable chair back 1 are laid flat, and then the chair can be changed into a lying state through the support of the short trapezoidal chair leg 6 and the high trapezoidal chair leg 3, so that the chair can be used not only in a sitting state but also in a lying state, further expanding the scope of application of the double chair.

[0022] Then, the expandable chair back 1 is inserted into the connecting block 4 through the chair back connecting rod 1-5, and connecting holes 1-1 are provided on both sides of the chair back connecting rod 1-5, and the chair back connecting rod 1-5 and the connecting block 4 are hinged by screws; through this structure, both sides of the chair back connecting rod 1-5 can be hinged and deformed, so that the chair back connecting rod 1-5 can normally play the role of driving the expandable chair back 1 to deform, and through the adjustment of the tightness of the screws, the chair back connecting rod 1-5 and the connecting block 4 can switch between a fixed state and a hinged rotation state, so that the deformation of the expandable chair back 1 can be carried out normally and the expandable chair back 1 can also play a supporting role.

[0023] Next, hinge connection holes 1-2 are provided at both ends of the lower plate 1-4, and the lower plate 1-4 is hingedly connected to the short trapezoidal chair legs 6 through hinges 5; through this mechanism, the operator can pass through the short trapezoidal chair legs 6.

[0024] At this time, a limiting plate 4 - 1 is provided at the front end of the connecting block 4 ; the limiting plate 4 - 1 prevents the expandable chair back 1 from being excessively pressed forward and affecting the normal use of the device.

[0025] Next, connecting buckles 8-1 are provided at both ends of the connecting plate 8, and the connecting buckles 8-1 are arranged in a curled shape. The bottom of the high trapezoidal chair leg 3 is connected to the connecting plate 8 by the connecting buckles 8-1; the connecting plate 8 limits the chair leg from excessive expansion or contraction, ensuring that the equipment can be used more stably.

[0026] It should be noted that the top of the high trapezoidal chair leg 3 is passivated to replace the role of the armrest and all sharp areas of the components are subjected to anti-collision treatment to passivate the sharp areas and avoid scratches on the user caused by the sharp parts.
