Description of drawings
Fig. 1 schematic perspective view of the present utility model.
Fig. 2 is of the present utility model to be the column and the inboard chute structural representation of crosspiece of bogie side frame.
The specific embodiment of the present utility model
Referring to accompanying drawing 1,2.
The improvement structure of the utility model two purpose sofas-beds, include framework, seat 1, backboard 2, framework is by left plate 9, right plate 10 and be connected crossbeam 11 and form, and the arc chute 3 of vertical direction and the arc chute 4 of horizontal direction are arranged on left plate 9, right plate 10 inboards.And backboard 2 two ends have rotating shaft 8 to be installed in the arc chute 3 of vertical direction, seat 1 two ends have rotating shaft 7 to be installed in the arc chute 4 of horizontal direction, and engineering nylon plastics sliding sleeve or metal sliding sleeve 5,6 all are installed in the arc chute 3 of vertical direction and the arc chute 4 of horizontal direction.
There are 90 very short degree bending parts arc chute 3 lower ends of the vertical direction on left plate 9, right plate 10 inboards; The arc chute 4 of horizontal direction respectively comprises two ends straight line chute.
During use, if allow bed become sofa, only need backboard 2 is pulled back, backboard 2 will slide to seat 1 and intersect the obtuse angle.And when sofa is become bed, then only need backboard 2 is pushed away forward, backboard 2 will slide to seat 1 on same plane.
