The sofa frame comprises a first rack body and a second rack body which are respectively provided with a positioning clamping groove; the sofa frame also comprises a left handrail frame, a right handrail frame, a seat bag frame and a backrest frame which are respectively provided with a connecting groove; the sofa frame also comprises clamping fixing units which are connected between the first rack body and the second rack body; the two ends of the clamping fixing units are respectively clamped in the positioning clamping grooves of the first rack body and the second rack body and the connecting grooves of the left handrail frame, the right handrail frame, the seat bag frame and the backrest frame; and the sofa frame is assembled into a whole by adopting the fastening and clamping mode through the clamping fixing units.
Description
Technical field
The present invention relates to a kind of sofa frame, be meant especially a kind of employing buckle into the mode that clamps assemble and decompose packaging volume urinate in the transportation sofa frame.
Background technology
As everyone knows, along with improving constantly of people's living standard, people loosen body and mind fully in busy needing after work, in order to realize that people can be from comprehensively loosening to the human body mentally, further improve the quality of having a rest, people produce and are fit to the furniture that human body is had a rest, and more typical furniture is such as sofa in these furniture.Sofa can be strong support people's health, and the force part such as shoulder, waist, the back of the body of human body is felt comfortably cool.The sofa of difference in functionality, style serves as that make on the basis with common sofa mostly.The primary structure of common sofa comprises, framework, inner support elastic component, elastic cushion, lining.
At first, framework is the foundation of sofa, also is the blank of sofa, is determining the moulding and the style of sofa.Sofa frame is that material is made with solid wood or brandreth mostly, when making framework, the seat surface of sofa and backrest will form the angle of an inclination, make sofa produce two strong points, supporting user's lumbar vertebrae and thoracic vertebrae, the effect of the curved surface that obtains to match with user's health back.Secondly,, give certain recovery elastic force also will for user's health, enough get supporting force and elastic force so the support elastic component of sofa must have because the support elastic component of sofa not only will bear the most weight of user's health.The support elastic component of sofa comprises support spring and elastic band, traditional manufacturing technique be with support spring vertically, side by side, on the intensive seat surface framework that is fixed on sofa, again elastic band is laterally intersected on the seat surface framework that is fixed on sofa with support spring, thereby strengthened the support ability and the elastic force of support elastic component.Once more, the elastic cushion of sofa is installed on seat cushion, backrest, the handrail.Not only need directly to bear the pressure that the user gives sofa, also to cushion to the pressure of human body to sofa, so the elastic cushion of sofa adopts the special-purpose sponge of high resiliency to make, form the softness thoughts and feelings when contact with human body, when avoiding human body contact simultaneously with sofa because oppress generation benumb and feel.At last, because the lining of sofa directly contacts with human body, unbalance stress can make the sofa surface produce distortion, so lining not only will be given the contact surface of a softness of people, also good restorability will be arranged.The general outsourcing lining that can make sofa according to the different styles of sofa, leather that different-style is selected in moulding for use or flannelette.
People in order comprehensively to be loosened, produced buttocks and the back that roomy support face comes the support user to sofa, so sofa have roomy framework when using sofa.In order to reduce the space that original sofa occupies, increase flexibility for people's productive life.People design and manufacture some collapsible sofas.Collapsible sofa folds by handrail and the backrest to sofa, thus the space that the reduction sofa occupies.But the overall volume of sofa after folding is still bigger, and the space that occupies is many.The large volume of sofa makes troubles for storage, transportation, the loading and unloading of sofa, meets the needs of the world for sofa enterprise and has brought certain negative effect.At first, because sofa all is a fixed frame, Folding sofa also is that folding, dismounting are realized in indivedual positions, and a large amount of products that store just need higher storage cost facing the market demand in enterprise.Thereby weakened Enterprises'Competitiveness.Secondly, because can't reduce the volume of sofa,, cause great inconvenience to transportation so the amount that container loaded under general traffic condition is extremely limited.In the face of a large amount of market demand time, just have only increase transport time time, not only improved cost of transportation, and can't the very first time market-oriented.At last, same because the volume of sofa is big, in cargo handling process, be carrying, move or loading, unloading all need to consume a large amount of time, human and material resources, not only make shipping and delivery cost higher, and directly influenced logistics cost.
As mentioned above, sofa is from original fixedly woodwork, to Upholstered sofa, have the function sofa of various functions to brandreth mechanism again, the intelligent sofa that band Based Intelligent Control function is arranged again now, people also more and more require flexible and changeable mode because of life, requirements of one's work simultaneously, and the market development of the sector globalization fully especially, so need to be convenient to dismounting and concentrate the sofa that packaged convenience carries.But present sofa all can't concentrate the technological improvement that packaged convenience is accomplished aspect carrying being convenient to dismounting, the packed and transported of sofa and carry or have great technical barrier, cause very big negative effect also for the globalization development of sofa market, up to the present sofa all be fixed some be that dismounting, packing are realized in indivedual positions, but packaging volume is still bigger, the packing wasting space is many, can't realize concentrating packing, cause great inconvenience and the high serious problems of cost with carrying for transportation, so necessaryly carry out technological improvement.Be the major defect of conventional art as mentioned above.
