Description
Technical field
It the utility model is related to household goods technical field；More particularly to a kind of sofa-bed structure.
Background technology
It is typically standing in family to have sofa and the big furniture of this two pieces of bed, but this two pieces furniture space-consuming is larger, for small
For house type resident family, it is provided with sofa and bed can be so that less space becomes more crowded originally, the life to people causes
Greatly trouble；When thering is the guest to come to visit in manager, such as need to stay, when bed is not enough in family, allows guest to sleep sofa and also lose courtesy,
Etc. these situations can all bring inconvenience.
A kind of convertible multi-functional couch disclosed in the U of China patent CN 202604221, it is characterised in that：Including
There are lower bed body and upper bed body, the lower bed body has the accommodation space of a storage upper bed body, and the upper bed body may be reversed ground with lower bed body
Pivot joint, after upper bed body descends bed body to be flipped up in place relatively, the upper bed body is located at the top of lower bed body and forms bunk beds knot
Structure, after upper bed body descends bed body to downwardly turn in place relatively, the upper bed body is accommodated in the accommodation space and forms sofa configuration.
Such convertible multi-functional couch, it is possible to achieve the combination of sofa and bed, reduction is separately provided bed and sofa accounts for
Space, when needed, upper bed body is overturn to form double-layer bed structure, convenient use relative to lower bed body, but is also deposited
In following defect：1st, when upper bed body is overturn relative to lower bed body, overturn using connecting at hinge as run-on point, one can be formed
It is individual so that, as the center of circle, the circle using the width of upper bed body as radius, space-consuming is bigger at hinge, can give upset change implementation make
Cheng Geng great difficulty；2nd, upper bed body is proof strength and security performance, and run-of-the-mill is larger, only using at two hinges as
Point is overturn, if lower bed body is not added with fixation, lower bed body can be caused to move in switching process；3rd, left the bed when upper bed body is turned to
Formed on body after bunk beds, the internal portion that leaves the bed is upwardly formed a chamber that can accommodate upper bed body, can not continue as sand
Hair uses, and can only be used as bed body, when needing to use sofa, need to overturn upper bed body to the chamber of lower bed body, troublesome in poeration
And can not meet the needs of sofa and bed simultaneously.
Utility model content
For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is：How a kind of energy is provided
Enough simpler conversion that can be realized between sofa and sofa-bed structure, can also meet people to sofa simultaneously after conversion
With the sofa-bed structure of the demand of bed.
In order to solve the above-mentioned technical problem, the utility model employs following technical scheme：In the application, direction definition
For using backrest do not rotate when sofa itself azimuth reference as direction standard.
A kind of sofa-bed structure, including a horizontally disposed cushion body, it is respectively perpendicular at left and right sides of the cushion body
A handrail is installed with, a backrest is provided with rear side of the cushion body, the backrest lower surface is arranged at the seat
Above pad upper surface, in addition to the support on rear side of the backrest is vertically provided at, after the pedestal lower end and the cushion body
End is fixedly connected, it is characterised in that the pedestal upper end is rotatablely connected by backrest rotating mechanism and the backrest upper end, described
Backrest upper end can rotate along the backrest rotating mechanism to be caused backrest to rotate to cushion body surface and is horizontal.
In the technical program, cushion body, handrail and backrest are provided with, support is provided with rear side of backrest, is simplest sand
Structure is sent out, backrest upper end is rotatablely connected with pedestal upper end by backrest rotating mechanism, and the lower surface of backrest is located at cushion
On the upside of the upper surface of body, it can preferably realize that backrest rotates along backrest rotating mechanism.Backrest along backrest rotating mechanism rotate to
During horizontality, give support and fix, the bed body that will be formed above cushion body.This sofa-bed structure has structure simple
Single, accessory cost is low and can preferably realize the conversion of the structure between sofa and divan, can be after conversion simultaneously
The effect of sofa and bed is played, saves the space of occupancy, the demand of people can be better met.
As optimization, the backrest rotating mechanism includes being arranged on the backrest inner upper end along the backrest length direction
Rotating shaft, the end of the rotating shaft is fixedly connected on the backrest, and the pedestal upper end is along the backrest length direction face
The rotating shaft is provided with rotating shaft slide opening, and the rotating shaft is rotatably arranged in the rotating shaft slide opening.
So, be provided with the rotating shaft in backrest and be arranged on the rotating shaft slide opening of pedestal upper end, rotating shaft can along turn
Axle slide opening rotates, and when backrest does not rotate, backrest upper end can be played a supporting role, when backrest is rotated to parallel with cushion body
During state, this backrest rotating mechanism can also play a supporting role to backrest.Simultaneously backrest phase is realized with simplest structure
Rotation for sofa, cost can be reduced, be also convenient for maintenance and installation.
As optimization, the support includes two vertically arranged support bars, and the support bar is symmetricly set on described lean on
Rear side, the support bar lower end are fixedly connected with the cushion body rear end, and upper end is respectively arranged with the rotating shaft slide opening.
