Description

Spring sofa

Technical Field

The invention relates to furniture, in particular to a spring sofa.

Background

A sofa is a common indoor furniture. To improve the comfort of the sofa, the existing sofa is usually equipped with a serpentine spring inside to perform elastic buffering. However, the serpentine spring is not durable and is likely to collapse or deform after long-term use.

Disclosure of Invention

The invention aims to provide a spring sofa, which can overcome the defects of the prior art and improve the durability of a serpentine spring in the sofa.

In order to solve the technical problems, the technical scheme adopted by the invention is as follows.

The utility model provides a spring sofa, includes sofa skeleton, installs the serpentine spring that a plurality of is parallel to each other in the sofa skeleton, and sofa cushion has been laid to serpentine spring's top, sofa skeleton's bottom is fixed with a plurality of support column, and the support column includes the base, and threaded connection has the cylinder on the base, and the cylinder top is provided with the blind hole, and first spring is installed at the blind hole center, and first spring top is connected with the ejector pin, and the top of ejector pin is connected with the backing sheet, and the edge of blind hole evenly is provided with a plurality of shell fragment, backing sheet and shell fragment interference fit.

Preferably, the edge of the supporting sheet is provided with notches which correspond to the elastic sheets one to one, rubber layers are wrapped in the notches, the elastic sheets are clamped in the notches in a sliding mode, and the elastic sheets are in interference fit with the rubber layers.

Preferably, a rubber gasket is fixed on the top of the supporting sheet, the edge of the rubber gasket comprises a plurality of extending portions, the thickness of the rubber gasket is gradually reduced from the center to the outer side end of each extending portion, each extending portion is located between two adjacent notches, and a plurality of second springs are arranged in the rubber gasket.

Preferably, both sides of the extension extend beyond adjacent notches.

Preferably, a plurality of cavities are formed in the rubber gasket, the second spring is installed in the cavities, the bottom of the second spring is fixedly connected with the cavities, and the top of the second spring is connected with a sliding sheet which is in sliding contact with the cavities.

Preferably, the two ends of the serpentine spring are fixed with connecting ends, the outer side of each connecting end is movably sleeved with a threaded sleeve, a threaded column matched with the threaded sleeve is fixed on the sofa framework, the threaded sleeves are in threaded connection with the threaded columns, each connecting end is provided with a threaded hole, each threaded column is provided with a through hole corresponding to the corresponding threaded hole, and the screw rod penetrates through the through holes and then is connected with the threaded holes.

Adopt the beneficial effect that above-mentioned technical scheme brought to lie in: the support column is additionally arranged on the basis of the traditional serpentine spring, and can synchronously deform when the serpentine spring deforms. When the support column produces deformation, the backing sheet moves downwards, and the shell fragment in the backing sheet outside is when keeping the vertical state of backing sheet, is propped open to the outside gradually along with moving down of backing sheet, supports the serpentine spring region outside the backing sheet to whole support column and serpentine spring's contact support stability has been improved. When the serpentine spring resets, under the combined action of shell fragment and first spring, serpentine spring can resume initial condition fast. The serpentine spring is in whole compressed and reset process, through the assistance and the protection of support column, can its produce the tired degree of spring by greatly reduced to prolong its life. The design of support piece edge breach is used for spacing the top of shell fragment. The rubber gasket of non-uniform thickness can improve its area of contact with serpentine spring when serpentine spring takes place to warp to improve the support effect of support column to serpentine spring. The second spring is used for improving the contact uniformity of the rubber gasket and the serpentine spring. The edge of the extension part is positioned in the notch, so that the direct friction between the elastic sheet and the serpentine spring can be reduced, and the noise and the part abrasion are reduced. In addition, the fixing structure of the serpentine spring is optimized, so that the stretching tension of the serpentine spring can be conveniently adjusted.
