Description

Technical Field

[0001] The utility model relates to the field of tools related to bed frame structures, in particular to a sofa base support frame. Background Art

[0002] The existing sofa spring base is generally surrounded by four frames, and then a number of serpentine springs are arranged longitudinally in the frame. In order to increase comfort, a structure such as a sponge pad is added above the serpentine spring. However, in the existing structure, since the sofa base is usually in direct contact with the ground, in humid areas, such as southern cities with more moisture or on the ground with poor water insulation effect, the sofa base is easily eroded by moisture, and the moisture will affect the elasticity of the serpentine spring, thereby affecting the service life of the sofa base. The moisture-proof performance is poor, which affects the user's experience. Therefore, there are many structures that use moisture-proof leather or other materials to make the sofa base shell. Although this structure has a certain moisture-proof effect, its manufacturing cost is high and it is not suitable for popularization. Utility Model Content

[0003] The utility model proposes a new sofa base support frame to solve one of the above-mentioned technical problems.

[0004] In view of this, the utility model proposes a new sofa base support frame, including a base frame, in which a palm pad layer, an elastic mesh layer, a woven belt layer, a tension spring layer, a support steel ring and multiple groups of supporting strip plates are arranged in sequence from top to bottom in the installation cavity of the base frame.

[0005] In the above technical scheme, a palm pad layer is first arranged at the bottom of the base frame. Since the palm pad layer has a low manufacturing cost and good water absorption and moisture-proof properties, it can effectively prevent water vapor from eroding the tension spring layer in the support frame through the underground, and can also effectively ensure the elasticity of the sofa; in addition, the elastic mesh layer and the woven belt layer can effectively improve the elasticity of the sofa frame, and the supporting steel ring and the supporting strip plate can effectively increase the stable supporting force of the supporting frame, so that the stability, balance, elasticity and moisture-proof of the base frame can be effectively improved, and the manufacturing cost is low, the overall structure is simple and reasonable, and it can also effectively improve the user experience.

[0006] Furthermore, vertical support springs are arranged at intervals at the bottom of the supporting strip plate, one end of the vertical support spring is arranged on the tension spring layer, and the other end of the vertical support spring is arranged at the bottom of the supporting strip plate.

[0007] In the above technical solution, the vertical support spring can provide elastic buffering force. When specifically configured, the annular diameter at the bottom is larger than the annular diameter at the top, which can provide buffering force when the user sits on the sofa.

[0008] Furthermore, the palm mat layer is made of woven palm grass, and four sides of the palm mat layer are fixed on the base frame.

[0009] Furthermore, the elastic mesh layer is made of a thin plastic pad, and four sides of the elastic mesh layer are fixed on the base frame.

[0010] Furthermore, the braided belt layer is made of a plurality of elastic belts that are woven in an interlaced manner, and both ends of each of the elastic belts are arranged on the base frame.

[0011] In the above technical solution, multiple elastic bands are interlaced and woven, which can provide elasticity while also providing stable and balanced support.

[0012] Furthermore, the tension spring layer is made of a plurality of serpentine springs arranged in an arranged manner.

[0013] Furthermore, the supporting steel ring is made of an annular steel bar, and the annular steel bar is fixed on the elastic mesh layer through a card.

[0014] Furthermore, mounting grooves are provided on the inner side walls at both ends of the base frame, and both ends of each serpentine spring are respectively engaged in the mounting grooves.

[0015] Furthermore, two ends of the plurality of supporting strip plates are mounted on two sides of the base frame by means of screws.

[0016] Compared with the prior art, the advantage of the utility model is that by arranging a palm pad layer, an elastic mesh layer, a woven belt layer, a tension spring layer, a supporting steel ring and multiple groups of supporting strip plates in sequence from top to bottom, the stability, balance, elasticity and moisture resistance of the base frame can be effectively improved, and the manufacturing cost is low, the overall structure is simple and reasonable, and it is easy to promote and mass produce.
