Detailed Description

The utility model will be further described with reference to specific examples, but the scope of the utility model is not limited thereto.

Example 1, a quick-folding frame sofa, as shown in fig. 1-15, comprises a seat cushion 1 and a frame 2, the seat cushion 1 being placed directly on top of the frame 2 (large frame 2-1 and small frame 2-2).

The frame 2 is designed integrally, and the frame 2 comprises a large frame 2-1 and a small frame 2-2.

The large frames 2-1 are two in number, and the large frames 2-1 comprise large frame cross rods 2-1-1 and large frame main bodies 2-1-3. The large frame main body 2-1-3 is a rectangular frame, the number of the large frame cross rods 2-1-1 is two, and the two large frame cross rods 2-1-1 are fixedly arranged in the large frame main body 2-1-3 in parallel.

The number of the small frames 2-2 is four, and the small frames 2-2 comprise small frame main bodies 2-2-1 and small frame cross bars 2-2-2. The small frame main body 2-2-1 is a rectangular frame, and the small frame cross bar 2-2-2 is fixedly arranged in the small frame main body 2-2-1.

The large frame 2-1 and the small frame 2-2 are both vertically arranged, and the large frame 2-1 and the small frame 2-2 are positioned on the same horizontal plane.

The two large frames 2-1 are arranged in parallel; each two small frames 2-2 are combined into a group of small frames, and the small frame main bodies 2-2-1 of the two small frames 2-2 are hinged with each other through external hinges 2-4; the two groups of small frames are arranged in parallel.

The large frame main body 2-1-3 of the large frame 2-1 is hinged with the small frame main body 2-2-1 of the small frame 2-2 through an internal hinge 2-5, and the large frame 2-1 and the small frame 2-2 are enclosed to form a rectangular frame 2.

The external hinge 2-4 is positioned at the outer side of the frame 2, and the internal hinge 2-5 is positioned at the inner side of the frame 2.

The large frame cross bar 2-1-1 of the adjacent large frame 2-1 and the small frame cross bar 2-2-2 of the small frame 2-2 are fixedly connected through a pipe hoop structure 2-3 to form a triangle.

The two large frame cross bars 2-1-1 of each large frame 2-1 are respectively connected with the small frame cross bars 2-2-2 of the two adjacent small frames 2-2 through two pipe hoop structures 2-3.

The hinges can be divided into an internal hinge 2-5 and an external hinge 2-4 according to different connection places. The small frame body 2-2-1 and the large frame body 2-1-3 are connected by two internal connection hinges 2-5, and the place adopting the connection method is provided with four places. The adjacent small frame bodies 2-2-1 are connected by two external hinges 2-4, and the connecting place by adopting the method has two positions.

The number of the pipe hoop structures 2-3 is four, and the pipe hoop structures 2-3 comprise first fixing seats 2-3-1, second fixing seats 2-3-5, first rivets 2-3-6, second rivets 2-3-7, extension rods 2-3-2, pipe hoops 2-3-4 and locking parts 2-3-3.

The head end of the extension rod 2-3-2 extends into the inner cavity of the pipe clamp 2-3-4 from the tail end of the pipe clamp 2-3-4, and the locking component 2-3-3 is arranged at the tail end of the pipe clamp 2-3-4. The tail end of the extension rod 2-3-2 is hinged with a first fixed seat 2-3-1 through a first rivet 2-3-6, and the head end of the pipe hoop 2-3-4 is hinged with a second fixed seat 2-3-5 through a second rivet 2-3-7.

The locking component 2-3-3 comprises a locking handle 2-3-3-1, a locking screw 2-3-3-2, a locking component rivet 2-3-3-3, a rubber mat 2-3-3-4 and a locking nut 2-3-3-5. The locking component rivet 2-3-3-3 is connected with the locking handle 2-3-3-1 and the locking screw 2-3-3-2, so that the locking handle 2-3-3-1 and the locking screw 2-3-3-2 can rotate relatively. The locking handle 2-3-3-1 adopts an eccentric wheel design, the locking handle 2-3-3-1 is fixedly connected with the eccentric wheel 2-3-3-6, and the locking component rivet 2-3-3-3 penetrates through an eccentric wheel hole of the eccentric wheel 2-3-3-6. The head end of the locking screw 2-3-3-2 penetrates through the locking part rivet 2-3-3, the tail end of the locking screw 2-3-3-2 is fixedly connected with the locking nut 2-3-3-5, and the middle of the locking screw 2-3-3-2 is sleeved with a rubber pad 2-3-3-4 matched with the locking handle 2-3-3-1. When in a loose state, a gap is reserved between the eccentric wheel and the rubber pad 2-3-3-4; when in a locking state, the eccentric wheel is abutted with the rubber pad 2-3-3-4.

The side wall of the tail end of the pipe hoop 2-3-4 is provided with a notch 2-3-4-3, the pipe hoop 2-3-4 is provided with a locking sheet 2-3-4-1 and a locking sheet 2-3-4-2 at two sides of the notch 2-3-4-3, the locking sheet 2-3-4-1 and the locking sheet 2-3-4-2 are both provided with locking sheet holes, the locking screw 2-3-3-2 penetrates through the locking sheet holes, and the locking sheet 2-3-4-1 and the locking sheet 2-3-4-2 are positioned between the locking nut 2-3-3-5 and the rubber gasket 2-3-3-4.

The eccentric wheel and the rubber pad 2-3-3-4 can generate an axial force to the locking screw 2-3-3-2 by rotating the locking handle 2-3-3-1. Due to the fact that the locking nut 2-3-3-5 and the locking screw 2-3-3-2 are restrained by threads, the distance between the rubber cushion 2-3-3-4 and the locking nut 2-3-3-5 is changed. The rubber gasket 2-3-3-4 presses the locking sheet 2-3-4-1 of the pipe hoop 2-3-4, the locking nut 2-3-3-5 abuts against the locking sheet 2-3-4-2 of the pipe hoop 2-3-4, and therefore the distance between the pressing sheet 2-3-4-1 and the pressing sheet 2-3-4-2 of the pipe hoop 2-3-4 can be changed by rotating the locking handle 2-3-3-1, the size of the caliber of the pipe hoop 2-3-4 can be influenced by changing the distance between the pressing sheet 2-3-4-1 and the pressing sheet 2-3-4-2, and the size of the caliber of the pipe hoop 2-3-4 can influence whether the extension rod 2-3-2 and the pipe hoop 2-3-4 can slide relatively or not. Thus, by rotating the locking knob 2-3-3-1, it is possible to influence whether the extension rod 2-3-2 and the pipe clamp 2-3-4 can slide relative to each other. The locking part 2-3-3 is used for rotating the locking handle 2-3-3-1 of the locking part 2-3-3, so that the locking part 2-3-3 influences the pipe hoop structure 2-3, and the whole structure has stability.

When in use, the large frame cross bar 2-1-1 of the adjacent large frame 2-1, the small frame cross bar 2-2-2 of the small frame 2-2 and the pipe hoop structure 2-3 form a triangle. When the extension bar 2-3-2 and the pipe clamp 2-3-4 of the pipe clamp structure 2-3 cannot slide relatively with the rotation of the locking handle 2-3-3-1, the triangle formed at this time has a stable shape. The large frame 2-1 and the small frame 2-2 are connected through the inner connection hinge 2-5, the small frame 2-2 and the small frame 2-2 are connected through the outer connection hinge 2-4, when the four locking handles 2-3-3-1 are rotated and locked, the corresponding pipe hoop structure 2-3 is locked, the large frame 2-1 and the small frame 2-2 connected with the pipe hoop structure 2-3 are locked, stability is achieved, and all the large frame 2-1 and all the small frames 2-2 are fixed, so that the whole frame is stable.

Finally, it is also noted that the above-mentioned lists merely illustrate a few specific embodiments of the utility model. It is obvious that the utility model is not limited to the above embodiments, but that many variations are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the present invention are to be considered within the scope of the utility model.
