Corresponding active force can be generated, which not only reduces stability, the safety of product on divan,
Also it is unfavorable for the service life of divan.
Summary of the invention
In view of the above-mentioned deficiencies in the prior art, providing one kind can be reduced in open or close the utility model
To the divan of the active force of divan, the sofa-bed structure is stable, highly-safe, service life is longer.
The utility model realizes that technical solution used by its technical purpose is: a kind of Novel sofa bed, including pedestal, sets
It sets the backrest above pedestal, the left and right handrail that pedestal two sides are set, the L shape being arranged in front of backrest and sits part, Yi Jishe
The support base for sitting and being used to support below part and sitting part is set, an extension means are respectively set between the seat part and left and right handrail, it is described to stretch
Mechanism is opened up to be symmetrical arranged.
Each extension means include connecting rod, rocking bar and fixed link, and three forms three-link mechanism.It is described to shake
Bar one end and connecting rod are rotatablely connected, and the other end and fixed link are rotatablely connected；One is equipped in the middle part of the rocking bar between fixed link
Spring.
The connecting rod upper end is fixedly connected with part is sat, and the fixed link is fixedly connected with handrail.
Preferably, being equipped with the extension means connecting rod of both connections between two extension means in left and right.Make left and right
Two extension means synchronous operations.
Preferably, being all uniformly provided in the rocking bar and fixed link multiple for pacifying spring-loaded through-hole.
Specifically, an exhausting hole is uniformly provided in the middle part of the rocking bar.The fixed link includes the fixed plate being vertically arranged, side
Plate is equipped with the connecting plate for connecting the two between the fixed plate and side plate.The fixed plate is fixedly connected with handrail, described
A column through-hole is uniformly provided on side plate.
The difference of the power-assisted of spring open or close according to required for divan is different from selection in fixed plate in rocking bar
Hole location spring, the pretightning force of adjustment spring be installed.
Preferably, the backrest is rotatably connected on left and right handrail.After seat part fully opens, backrest is turned to
Horizontal plane cooperates with support base and fixes, and the Overall Steps for becoming bed by sofa can be completed；When seat part needs to withdraw, by backrest
Go back to original position.
Preferably, the connecting rod is the sheet sheet metal component of L shape.The L shape connecting rod is a piece of and is arranged upper
The seat part of side is fixedly connected, and another is rotatablely connected with rocking bar.
Preferably, the connection rod rear end is equipped with the limit shaft for limiting rocking bar hunting range.When sitting part opening, shake
Bar is swung forward, and when sitting part and reaching predetermined position, (position after sitting part movement can accommodate required position after backrest overturning
Set), part bottom and ground face contact are sat, limit shaft offsets with rocking bar, supports by extension means and sits part.
The beneficial effects of the utility model are: 1, by three-link mechanism drive sit part opening and closing, structure is simple, behaviour
Facilitate.2, also subtracted while to power-assisted is generated when sitting part opening and closing by the setting of spring between rocking bar and fixed link
Lack and sat part in opening and closing to the impact of divan and collision, has prolonged its service life.3, extension means connecting rod connects
Two extension means in left and right are connect, left and right two parts extension means is run simultaneously, keeps the driving of divan more steady, guarantee it
Comfort and safety.
