In the sofa form, the spring 9 tightens the pedal 8, a notch of a limiting block 10 fixed with the pedal 8 is buckled on the positioning pin 7, the second connecting rod 5 is locked to rotate upwards, the sofa form is not changed, when the pedal 8 is stepped, the notch on the limiting block 10 leaves the positioning pin 7, the second connecting rod 5 is not constrained to operate upwards to drive the first connecting rod 4, the third connecting rod 6 operates to support the first bed plate 2 and the second bed plate 3 simultaneously, and when the pedal 8 is forced to move, the spring 9 elastically returns to drive the pedal 8 to return. After the first bed board 2 and the second bed board 3 are supported, the limiting device limits the first bed board 2 and the second bed board 3 in order to prevent the first bed board and the second bed board from generating other form changes.

Stop device is including setting up first dog 11 on third connecting rod 6, setting up arc spout 12 on first bed board 2 and second bed board 3 articulated position, and first dog 11 carries out the angle restriction to second bed board 3 and third connecting rod 6, and arc spout 12 is to the rotation angle restriction of first bed board 2 with second bed board 3. First dog 11 sets up on third connecting rod 6 and sets up two, and first dog 11 has two flanges at least, and under sofa or bed state, the first dog 11 that sets up in the below has a flange and can supports third connecting rod 6 and restrict third connecting rod 6 and continue to rotate, prevents that second bed board 3 from rotating downwards and leading to the bed state unstable, and under bed and sofa form, the first dog 11 that sets up at the upside has a flange and can support second bed board 3 and restrict second bed board 3 and rotate. Clamping grooves are formed in two ends of the arc-shaped sliding groove 12 and can limit the rotation angle of the second bed board 3, the hinged end of the second bed board 3 and the hinged end of the first bed board 2 can slide on the arc-shaped sliding groove 12 for a certain angle, when the sofa bed is in a sofa shape, the hinging of the second bed board 3 is limited by the upper clamping position of the arc-shaped sliding groove 12, the second bed board 3 cannot continuously rotate towards the direction of the first bed board 1, the second bed board 3 and the first bed board 2 form a certain angle, the second bed board 3 serves as a sofa backrest, and the formed angle meets the requirement of the backrest; when the sofa is in a bed shape, the lower clamping groove of the arc-shaped sliding groove 12 limits the second bed board 3 to rotate downwards, and at the moment, the second bed board and the first bed board are on the same plane and are connected into a whole.

This sofa bed still includes the connecting rod handrail, and the connecting rod handrail includes first pole 13,

second pole

14, and 13 one end of first pole are articulated with first bed board 2, and the other end is articulated with second pole 14, and the one end that first pole 13 was kept away from to the second pole is articulated with second bed board 3. Under the sofa form, the connecting rod handrail serves as a handrail, and the rest is convenient. In the bed form, since the first bed plate 2 and the second bed plate 3 are on the same plane, the first rod 13 and the second rod 14 are also connected in a straight line, and the bed plate 2 and the second bed plate 3 are flush with each other. A second stopper 15 is arranged at the hinged position of the first rod 13 and the second rod 14, when the first rod 13 and the second rod 14 are in a straight line book, the second stopper 15 presses the first rod 13 and the second rod 14, and simultaneously the first bed board 2 and the second bed board 3 connected with the first rod are also pressed, so that the first bed board 2 and the second bed board 3 are limited to rotate upwards by taking the hinged position as a base point.

The utility model discloses an application method is under the form of bed, stopper 10 on the locking device blocks locating pin 7, pins first connecting rod 4, second connecting rod 5, third connecting rod 6 motionless, and first bed board 2 forms certain angle with second bed board 3 because of the support of third connecting rod 6 and the restriction of arc spout 12 that first bed board 2 and the articulated department of second bed board 3 set up, and its support mode is the first dog 11 of above setting, and second bed board 3 is the sofa back, the seat district of first bed board 2 and sofa. When the pedal 8 in the locking device rotates downwards under the action of force, the limiting block 10 fixed with the pedal is driven to rotate upwards, the gap of the limiting block 10 is not buckled on the positioning pin 7, the locking device is opened, the sofa shape is not locked, the first connecting rod 4, the second connecting rod 5 and the second connecting rod 6 rotate simultaneously, the first connecting rod 4 and the second connecting rod 5 are kept parallel from beginning to end in the rotating process, when the first connecting rod 4 and the second connecting rod 5 rotate to the vertical angle, the third connecting rod 6 also rotates to the corresponding position, the lower side first stop block 11 arranged on the third connecting rod 6 fixedly supports the third connecting rod 6 to prevent the third connecting rod 6 from continuing rotating, the upper boundaries of the first connecting rod 4, the second connecting rod 5 and the third connecting rod 6 after rotating are parallel and level, so that the first bed board 2 and the second bed board 3 form a large bed board together, the upper side first stop block 11 on the third connecting rod 6 supports the second bed board 3, meanwhile, the lower clamping position of the arc-shaped sliding groove 12 at the hinged position of the first bed board 2 and the second bed board 3 limits the angle of the second bed board and cannot rotate downwards continuously, and the second stop block 15 at the hinged position of the first rod 13 and the second rod 14 presses the first bed board 2 and the second bed board 3, so that the state of the bed is also stably fixed. When the bed shape is changed back to the sofa shape, the sofa state is locked by only pushing up the second bed board 3 and pressing down the first bed board 2 and buckling the positioning pin 7 again by using the limiting block 10 on the locking device.

The above embodiments are not limited to the technical solutions of the embodiments themselves, and the embodiments may be combined with each other into a new embodiment. The above embodiments are only used for illustrating the technical solutions of the present invention and are not limited thereto, and any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be covered by the scope of the technical solutions of the present invention.
