DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0043] The present application provides a Figures 1-4The illustrated combination sofa bed chair comprises a bearing seat 1, an armrest 2, a pin shaft 3, a positioning mechanism 4, a connecting mechanism 5, a pulling handle 6 and a backrest 7. The bearing seat 1 comprises a frame 11, bearing plates 12 and arc-shaped grooves 13. A plurality of bearing plates 12 are fixed equidistantly on the top of the frame 11, so that the plurality of bearing plates 12 can be used for bearing. The arc-shaped grooves 13 are arranged on both sides of the end of the frame 11 and are composed of a plurality of continuous circular grooves. The armrest 2 is arranged on the end of the bearing seat 1 and is rotatable on the end of the frame 11 through the pin shaft 3. The pin shaft 3 is fixedly inserted into the end of the bearing seat 1. The armrest 2 is rotatably connected to the end of the bearing seat 1 through the pin shaft 3. That is, the pin shaft 3 is fixed on the end of the frame 11, and the armrest 2 is rotatably inserted into the pin shaft 3. When the armrest 2 is perpendicular to or inclined to the frame 11, a cushion is arranged on the top of the bearing seat 1 and the side of the armrest 2, so that the combination sofa bed chair can be used as a sofa.

[0044] The positioning mechanism 4 is arranged on the side of the bottom of the armrest 2, and the connecting mechanism 5 is arranged between the two positioning mechanisms 4. The connecting mechanism 5 is used for relative movement of the two adjacent positioning mechanisms 4. The positioning mechanism 4 is used for fixed insertion of the armrest 2 and the end of the bearing seat 1 at different angles. The positioning mechanism 4 comprises a positioning pipe 41, a movable rod 42 and a tooth block 43. The positioning pipe 41 is fixed on the inner wall of the bottom of the armrest 2. Adjacent two positioning pipes 41 are arranged oppositely. The movable rod 42 is slidably inserted into the inner cavity of the positioning pipe 41. One end of the movable rod 42 is slidably and insertingly connected to the inner cavity of the adjacent arc-shaped groove 13. A plurality of tooth blocks 43 are fixed on the other end of the movable rod 42. The plurality of tooth blocks 43 on the same movable rod 42 are fixed equidistantly.

[0045] Specifically, the positioning pipe 41 comprises a pipe body 411, a pull spring 412 and a positioning plate 413. The pipe body 411 is fixed on the inner wall of the bottom of the armrest 2. The pull spring 412 is fixed on one end of the pipe body 411. The positioning plate 413 is fixed on one end of the pull spring 412. The pull spring 412 is used for elastic pulling of the positioning plate 413.

[0046] More specifically, the movable rod 42 comprises a rod body 421, a clamping block 422 and a bent part 423. The rod body 421 is slidably inserted into the inner cavity of the pipe body 411. The positioning plate 413 is fixedly inserted into the middle part of the rod body 421. The clamping block 422 is fixed on the outer wall of the rod body 421. The bent part 423 is bent on the middle part of the rod body 421. The clamping block 422 is slidably and insertingly connected to the inner cavity of the pipe body 411, so that the rod body 421 cannot rotate in the inner cavity of the pipe body 411 at will. The rod body 421 is insertingly connected to the inner cavity of the pull spring 412. The positioning plate 413 and the middle part of the rod body 421 are fixed, so that the pull spring 412 can elastically pull the rod body 421. When there is no external pulling force, the rod body 421 is in the inserted state in the inner cavities of different circular grooves of the arc-shaped groove 13, so as to improve the stability of the armrest 2 at the end of the frame 11.

[0047] The connecting mechanism 5 is arranged at the middle of the opposite end of the two movable rods 42, and comprises a fixed rod 51, a rotating rod 52 and a connecting gear 53. The fixed rod 51 is fixed to the bottom of the handrail 2. The bottom of the rotating rod 52 is rotatably connected to the middle of the fixed rod 51 through a bearing. The connecting gear 53 is fixed to the middle of the rotating rod 52. The two sides of the connecting gear 53 are respectively engaged with the tooth blocks 43 on the two movable rods 42. The tooth blocks 43 are fixed to the one end of the rod body 421 close to the connecting gear 53. When one of the rod bodies 421 is pulled, the other rod body 421 in the opposite state is in a relative motion state, so that the two rod bodies 421 can simultaneously slide out of or slide into the two arc-shaped grooves 13 at the same end of the frame 11, thereby improving the stability and convenience of the connection between the handrail 2 and the frame 11.

[0048] In addition, the pulling handle 6 is arranged on the outer wall of one of the positioning mechanisms 4. One of the rod bodies 421 in the adjacent two rod bodies 421 is fixedly connected with the pulling handle 6. By pulling the pulling handle 6, the pulling of the rod body 421 is more convenient, so as to conveniently adjust the angle between the handrail 2 and the bearing seat 1, and conveniently use the combined sofa bed chair as a sofa or a bed body. The backrest 7 is fixed to one side of the bearing seat 1. One side of the frame 11 is fixedly connected with the bottom of the backrest 7. By the backrest 7, the combined sofa bed chair can be leaned on the back, thereby improving the use performance of the combined sofa bed chair.

[0049] Finally, it should be noted that: the above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or equivalently replace some of the technical features, as long as they are within the spirit and principles of the present application. Any modification, equivalent replacement, improvement, etc. made within the scope of the present application shall be included in the protection scope of the present application.
