Description

The plum blossom spring hinge

Technical field

The utility model relates to Furniture fittings accessory field, relates generally to a kind of plum blossom spring hinge that is used on the sofa.

Background technology

Sofa has been the essential furniture of many families.The sofa of selling on the market generally has low back of the body sofa, high back of the body sofa and between three kinds in the common sofa between the above two.Low back of the body sofa: the easy chair that belongs to the rest type.It comes support user's this sofa backrest height of waist (lumbar vertebrae) lower with a strong point, and generally apart from seat surface 370 millimeter, the angle of backrest is also less, not only helps having a rest, and makes corresponding the dwindling of whole sofa Outside Dimensions.This sofa is moved more convenient, light and handy, and floor space is little.High back of the body sofa: claim aviation formula seat again.Its feature is that three fulcrums are arranged, and people's waist, shoulder, hindbrain are leaned against on the curved surface backrest simultaneously.These three strong points spatially do not constitute straight line, thereby it is higher to make this sofa specification requirement, and it is also bigger to select difficulty during purchase.Manufacture the yoke of high back of the body sofa, must carry out 3 turnover faces that constituted on the top of the shelf clearly, otherwise discomfort is brought to the user in the position that just is difficult to guarantee the strong point when carrying out operations such as sofa is masked.Whether the formation of choosing three strong points will noting its back side when height is carried on the back sofa is reasonable, appropriate, can be judged by the examination seat.High back of the body sofa develops from chaise longue and forms.For improving the rest performance, also can manufacture footstool, before the placement sofa, its height can be identical with the forward position height of sofa seat surface.Common sofa: be common a kind of in the home-use sofa.That sells on the market mostly is this class sofa.It has two strong point support users' lumbar vertebrae, thoracic vertebrae, the effect of the curved surface that can obtain to match with the health back.The angle of this type of sofa backrest and seat surface is very crucial, and excessive or too small user's the abdominal muscles that all will cause of angle is strong, produces tired.Equally, the width of sofa seat surface is also unsuitable excessive, presses standard-required usually within 540 millimeters, and user's shank can arbitrarily be adjusted sitting posture like this, has a rest more comfortablely.But be which kind of sofa all be unable to do without the accessory of forming sofa.Good accessory not only can guarantee the service life of whole sofa, and the people is sitting on the sofa more comfortable.

Summary of the invention

The purpose of this utility model aims to provide a kind of plum blossom spring hinge that is used on the sofa.The utlity model has characteristics simple in structure, that flexibility is strong, easy to use.

The utility model is achieved through the following technical solutions:

The plum blossom spring hinge is characterized in that: comprise two hinge parts, be respectively arranged with the screwed hole of identical size on the described hinge part, described two hinge parts are connected by the spring bolt with the screwed hole coupling.

Described hinge part is provided with aperture.

Described screwed hole periphery is provided with equally distributed projection.

During use, spring bolt passes and is arranged on the screwed holes of two hinges on the part and will cut with scissors part and connect, and can make the rotation of two hinge parts very easily.Because two screwed hole peripheries that cut with scissors on the part all are provided with equally distributed projection, when it is rotated, can fasten mutually, be difficult for loosening.All be provided with aperture on two hinge parts, be convenient to be connected with other parts.Dismounting also is easy to, and it is quite convenient to use.

The utlity model has following advantage:

1, adopts spring bolt will cut with scissors the structure that part connects and cooperate projection, two hinge parts are easily rotated, and fasten firmly, be difficult for loosening.

2, all be provided with aperture on two hinge parts, conveniently be connected with other parts.

3, simple in structure, flexibility is strong, easy to use.
