The outside channel-shaped bar 12 of horizontal folding stull is provided with draw ring 13.
Below with drawings and Examples explanation this utility model.
Accompanying drawing 1, this utility model structural representation.
Among the figure: 1 tee pipe coupling, 2 put the beams in place 3 underbeams, 4 vertical pivoted housings, 5 locator cards, 6 poles, 7 horizontal pivoted housings, 8,8 ' upper strata channel-shaped bar, 9 chair cushions, 10 handlebar vertical rods, 11 connecting rods, 12,12 ' lower floor's channel-shaped bar, 13 draw rings.
Folding seat frame as shown in Figure 1, its upper beam 2 and underbeam 3 junctions, upper and lower beam and handlebar vertical rod 10 junctions and pole 6 are equipped with tee pipe coupling 1 with the underbeam junction, and welding is fixing.Be fixed with the upper end between the upper and lower beam of each side chair frame and be the pole 6 of " Qian " shape locator card 5, and front and back distribute 2, each pole is set with vertical pivoted housing 4, that connect by axle and can embed joint mutually two lower floor's channel-shaped bar 12,12 ' the horizontal folding stull that constitutes, two ends are fixedly connected respectively at corresponding vertical pivoted housing, the connecting axle of front and back horizontal folding stull is equipped with connecting rod 11, and preceding horizontal folding stull outside channel-shaped bar also is provided with draw ring 13.
Be provided with the horizontal pivoted housing 7 that is sleeved on upper beam 2 in " Qian " shape locator card 5 of each pole, that connect by axle and can embed joint mutually two upper strata channel-shaped bar 8,8 ' the vertical folding stull that constitutes, its two ends are fixedly connected respectively at corresponding horizontal pivoted housing, and the channel-shaped bar 8 that is positioned at the top of front and back vertical folding stull is chair cushion 9 fixedly.
This chair frame is when user mode, and two chair framves are supported by the stull of difference support direction respectively, and its stability is greatly improved.When the chair frame folds, pull draw ring and carry out simultaneously with the rollover chair cushion, making level, vertical folding stull respectively is the folding position, and both sides chair frame is promptly drawn close.
The utlity model has simple in structure, firmly, the remarkable advantage of supporting ﹠ stablizing.
