Description
Technical field
The utility model relates to the field of household goods, special relevant to a kind of foldable structure of divan.
Background technology
Divan, with the using function of sofa and bed, takes up room little, uses flexibly, is applicable to using at home.General divan needs complicated step when converting sofa or bed, need to lift or move, effort is compared in operation, sometimes also need other people to assist to complete, therefore the deficiency on traditional structure how is overcome, make conversion sofa that divan can be laborsaving, light or bed be the directions that the present inventor considers, this case produces thus.
Utility model content
The purpose of this utility model is the folding rotational structure providing a kind of divan, can Fast transforms using function, has light, the labour-saving feature of operation.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of folding rotational structure of divan, include seat frame and back rest, and by the connector of seat frame together with back rest moving jointing, described connector is integrally connected to form by upper connecting rod and lower link, forms the angle being greater than 90 ° between upper connecting rod and lower link, and upper connecting rod is fixedly connected with back rest, lower link and the rotatable pivot joint of seat frame, after connection, connector can rotate around the pivoting point of this lower link and seat frame, and the bottom of described lower link is provided with roller.
The upper end of described connector lower link is provided with a pivot hole, and a connecting pin penetrates pivot hole and lower link and seat frame is rotatably articulated.
Described connector is symmetricly set on the both sides of seat frame and back rest, is also provided with the crossbeam of load-bearing effect together between two connectors, and this crossbeam is positioned at the below of seat frame, and two ends are connected with the lower link of two connectors respectively.
Described seat frame is provided with the spike of supporting chair.
The back side of described back rest is provided with foldable support bar.
Adopt said structure, the utility model, by the lower link of push-and-pull connector, makes connector around connecting pin clockwise or be rotated counterclockwise, can easily back rest be lifted or put down, the using function of conversion divan, operate very light, laborsaving, structure is also very simple.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Figures 1 to 5, for the folding rotational structure of a kind of divan of the utility model, include seat frame 1 and back rest 2, and by the connector 3 of seat frame 1 together with back rest 2 moving jointing, described connector 3 is integrally connected to form by upper connecting rod 31 and lower link 32, the included angle A being greater than 90 ° is formed between upper connecting rod 31 and lower link 32, the upper connecting rod 31 of connector is fixedly connected with back rest 2, lower link 32 pivot joint rotatable with seat frame 1 of connector, the upper end of this lower link 32 is provided with a pivot hole 321, one connecting pin 322 penetrates this pivot hole 321 and lower link 32 and seat frame 1 is rotatably articulated, after connection, connector 3 can connecting pin 322 be axle rotation, the bottom of described lower link 32 is provided with roller 323, the present embodiment preferably this connector 3 is symmetricly set on the both sides of seat frame 1 and back rest 2, and is also provided with the crossbeam 4 of load-bearing effect together between two connectors 3, and crossbeam 4 is positioned at the below of seat frame 1, and two ends are connected with the lower link 32 of two connectors 3 respectively.
Described seat frame 1 is provided with the spike 11 of supporting chair.
The back side of described back rest 2 is provided with foldable support bar 21.
As shown in Figure 1, 2, when doing sofa use, promote the lower link 32 of connector, connector 3 is turned clockwise around connecting pin 322, at this moment lower link 32 beat backward of connector 3,31, upper connecting rod drive back rest 2 together relatively seat frame 1 upwards lift, the roller 323 of this process lower link 32 bottom on the ground, has coordinated the effect of supporting chair with the spike 11 of seat frame by unsettled to earth surface and final stable support.As shown in Figure 3,4, when bed uses, then reverse push follower link 3, connector 3 is rotated counterclockwise around connecting pin 322, it is concordant with seat frame 1 that upper connecting rod 31 drives back rest 2 to lower backward together, and the roller 323 of this process lower link slides forward along ground and leaves ground to lifting gradually, and back rest 2 and seat frame 1 are at grade, again the support bar 21 at back rest 2 back side is put down support on the ground, form the structure of bed.
Visible, adopt said structure, the utility model is by the lower link of push-and-pull connector, make connector around connecting pin clockwise or be rotated counterclockwise, can easily back rest be lifted or put down, the using function of conversion divan, operate very light, laborsaving, structure is also very simple, and make easily, cost is low.
The above, be only the utility model preferred embodiment, therefore can not limit with this scope that the utility model implements, the equivalence namely done according to the utility model claim and description change with modify, all should still belong in scope that the utility model patent contains.
