Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 and 3, a sofa spring frame comprises a support frame 1, wherein the support frame 1 comprises two longitudinal beams 11 parallel to each other and two cross beams 12 parallel to each other, and the longitudinal beams 11 and the adjacent cross beams 12 are connected end to form a rectangular structure; a plurality of supporting beams 3 are fixed between the two longitudinal beams 11, the supporting beams 3 are perpendicular to the longitudinal beams 11 and are parallel to the cross beam 12, and a plurality of supporting groups 5 are fixed on the supporting beams 3; a plurality of serpentine springs 4 are arranged between the two beams 12, two ends of each serpentine spring 4 are detachably connected with the two beams 12 through buckles 6, and the serpentine springs 4 are positioned at the tops of the support groups 5. The support frame 1 is the main structure part in the sofa, and when people used the sofa, the support frame 1 atress was frequent, and stress variation is obvious, if adopt traditional welding mode to connect crossbeam 12 and longeron 11, the welding point is in easily taking place fatigue fracture under the frequent stress variation condition, so crossbeam 12 and longeron 11 adopt integrated into one piece technique, have provided better structural strength for support frame 1. The supporting beam 3 is fixed between the two longitudinal beams 11 in a welding mode and is perpendicular to the longitudinal beams 11, and the supporting beam 3 is fixed in a welding mode, so that the production cost is saved. The number of the support beams 3 can be properly adjusted according to the size of the support frame 1, the larger the support frame 1 is, the more the number of the support beams 3 is, and the three support beams 3 are arranged in the embodiment. The number of the support groups 5 can be adjusted according to the length of the support beam 3, and the longer the length of the support beam 3 is, the more the number of the support groups 5 is, and three support groups 5 are provided on each support beam 3 in this embodiment. The serpentine spring 4 is arranged between the two beams 12, and the middle part of the serpentine spring 4 is above the support group 5, when a person sits on the sofa, the serpentine spring 4 is firstly pressed downwards and transmits the pressure to the top of the support group 5, and then the support group 5 gives different support forces to the serpentine spring 4 according to the magnitude of the pressed force.

As shown in fig. 5, the supporting set 5 includes a base 51, one end of the base 51 is fixed on the supporting beam 3, the other end of the base 51 is provided with a first slideway 54, a first spring 55 is fixed in the first slideway 54, the other end of the first spring 55 is fixed with a first sliding block 52, the first sliding block 52 slides in the first slideway 54, and the other end of the first sliding block 52 extends out of the first slideway 54; one end of the first slide block 52 extending out of the first slide way 54 is provided with a second slide way 56, a second spring 57 is fixed in the second slide way 56, the other end of the second spring 57 is fixed with a second slide block 53, the second slide block 53 slides in the second slide way 56, and the other end of the second slide block 53 extends out of the second slide way 56. The first spring 55 and the second spring 57 are springs with different elastic coefficients, in this embodiment, the first spring 55 is a spring with a large elastic coefficient, and the second spring 57 is a spring with a small relative elastic coefficient. When the top of the support group 5 is pressed by the serpentine spring 4, the second slider 53 is pressed. At this time, if the pressure is small, the second spring 57 is compressed by a large amount, and the first spring 55 is compressed by a small amount; at this time, if the pressure is high, the second spring 57 is fully compressed, and the first spring 55 can be continuously compressed after the second spring 57 is fully compressed. Because the support group 5 adopts a two-section spring structure, when a person with a large weight sits on the sofa, the first spring 55 is still in a normal elastic force range, and can provide enough support for the user; when a person with a small weight sits on the sofa, the second spring 57 can also generate corresponding compression, so that the problem of over-hardness of the two sofas is avoided while the support performance is ensured.

As shown in fig. 1, the anti-falling device is disposed at one end of the first slide block 52 in the first slide way 54 and at one end of the second slide block 53 in the second slide way 56. The first sliding block 52 and the second sliding block 53 are both cylindrical structures, the anti-falling-out device is a circular ring respectively sleeved at one end of the bottom of each cylindrical structure, the two circular rings are both provided with larger diameters than the matched cylindrical structures, and the first slide way 54 and the second slide way 56 are respectively matched with the sizes of the two circular rings.

As shown in fig. 2 and 4, a positioning groove 58 is provided at the top end of the first slider 52, a positioning rod 59 is fixed in the positioning groove 58, and the serpentine spring 4 is close to the positioning rod 59. In the installation process, the serpentine spring 4 can be fixed on the positioning rod 59 through a plastic binding belt, so that the positioning function is achieved, and the subsequent disassembly, assembly and maintenance are facilitated.

As shown in fig. 3, the buckle 6 includes an arc-shaped section and straight-line sections at two ends of the arc-shaped section, a through hole is formed on the straight-line sections, and the buckle 6 is bolted to the cross beam 12 through the through hole. In the installation, insert the arc section of buckle 6 with the one end of snake spring 4 in, then screw up the bolt on the 6 straightways of buckle, make buckle 6 compress tightly 4 both ends of snake spring on crossbeam 12, in follow-up maintenance process, change snake spring 4 and only need loosen the bolt and can pull down snake spring 4.

As shown in fig. 2 and 3, the longitudinal beam 11 has an arc-shaped structure with a concave central portion. The concave arc-shaped structure can make the user experience with heavy weight more comfortable, and prevent the user from sitting on the sofa and causing the thigh to be clamped on the frame due to the height reduction of the body.

As shown in fig. 1, the supporting frame 1 is provided with a plurality of mounting holes 7. The mounting holes 7 that are reserved can be used for mounting other components in the sofa.

As shown in FIG. 1, the serpentine spring 4 is of a composite structure, and the surface of the serpentine spring 4 is wrapped with an elastic flexible material. The composite structure can reduce the corrosion of the serpentine spring 4 in a humid use environment and avoid abnormal sound caused by rust in the working process.

As shown in fig. 1, the support beam 3 is perpendicular to the longitudinal beams 11 and parallel to the cross beam 12. The vertical arrangement of the support beams 3 provides a higher structural strength to the support frame 1.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
