Description
Technical field
The utility model is related to technical field of furniture, relates more specifically to a kind of with the divan stretched with folder function
Frame.
Background technology
With the development of society, due to the limitation of Modern Family and working space, people have for the effect of couch
It is more to require.Except that chair frame part can be folded up in addition to the function of common couch, at the same again can by from
Favorite places out rest chair frame Part draw as divan for sleep.Although many manufacturers are all being devoted to life now
This divan with stretching collection function of all kinds is produced, but these sofa-bed structures are complicated, install cumbersome, high cost,
The defects such as shelf generally existing stability is poor, easily rock, rigid deficiency.
Utility model content
The utility model is to overcome at least one defect described in above-mentioned prior art, there is provided one kind is with stretching, extension and folds
The sofa bedstead of function.The utility model simple structure, it is easy to use, divan can be made to receive the more save space that gathers into folds, during expansion
It is more laborsaving.
In order to solve the above technical problems, the technical solution adopted in the utility model is：One kind is with stretching, extension and folder function
