Abstract
The utility model belongs to the field of sofa manufacture and in particular relates to a double zigzag spring assembly for a sofa seat frame. The double zigzag spring assembly for the sofa seat spring comprises a main zigzag spring group and reinforcing zigzag springs; the main zigzag spring group comprises at least two zigzag springs in the seat frame in parallel; part or all of the zigzag springs are provided with the reinforcing zigzag springs in a staggering manner, and thus a double zigzag spring structure in a gourd string type is formed. The sitting feel of a sofa is improved according to the technical scheme provided by the utility model; a cushion is not too soft, and thus the continuity of elastic force of the reinforced springs is effectively ensured; a rollover force to a side generated when an iron stand is opened can be reduced by reinforcing the side zigzag springs, and thus the sitting balance is kept.
Description
Technical field
The utility model belongs to sofa and manufactures field, is specifically related to a kind of two snake spring assemblies for the sofa seat frame.
Background technology
Sofa mainly comprises seat, handrail and backrest, the fabric that wherein seat comprises seat frame, is fixed on spring assembly in seat frame, is arranged on the inserts on spring assembly and is coated with part forms, and wherein the comfort of spring assembly and structure thereof and sofa is closely related.
As shown in Figure 1, prior art medi-spring assembly comprises the snake spring 11 of a plurality of parallel arrangements, snake spring 11 1 ends pass through on the fixing front Wooden Batten 12 of being present of snak link 14, snake spring 11 other ends are fixed present rear Wooden Batten 13 by snak link 14, between spring 11, by paper bag steel wire in seat 15, reinforce, described snake spring 11 is single snake spring structure, and phenomenon easily occurs to roll when keeping to the side the side seat.And single snake spring structure cushion, the seat sense is partially soft, and the fluctuating drop is large.
The utility model content
Technical problem to be solved in the utility model is single snake spring structure cushion, and while keeping to the side the side seat, easy generation inclination phenomenon and seat feel partially soft, and the fluctuating drop is large, in order to overcome above deficiency, provides a kind of two snake spring assemblies for the sofa seat frame.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: described two snake spring assemblies for the sofa seat frame comprise main snake spring group and reinforce the snake spring, described main snake spring group comprises at least two the snake springs of parallel arrangement in seat frame, wherein on part or all of snake spring, dislocation is provided with and reinforces the snake spring, is the two snake spring structures of cucurbit serial type.But snake spring structure hardness is stronger, the fluctuating drop is little for two snake spring structures.
Further, two snake springs that are positioned at avris in described main snake spring group are provided with the reinforcing spring, are two snake spring structures, can prevent from rolling when keeping to the side the side seat.
Further, described snake spring band angle, the bending angle of snake spring is connected with Wooden Batten after seat, and the seat frame rear portion is raised, has increased rear subsides power, and the seat sense is more comfortable.
Further, described reinforcing snake spring and snake spring are fixed by adding flat nail.
Further, described two snake spring assemblies for the sofa seat frame also comprise the paper bag steel wire, and described paper bag steel wire is arranged between the snake spring of main snake spring group, prevents from relatively rocking.
Further, described paper bag steel wire, snake spring and reinforcing snake spring intersection, the paper bag steel wire is fixedly connected with by adding flat nail with the snake spring, reinforces the snake spring and is not fixedly connected with the snake spring at this place.
The technical scheme that the utility model provides has promoted the sofa seat sense.Make cushion can be too soft, effectively guarantee to be reinforced the elastic force continuation of spring, the reinforcing of avris snake spring can be reduced in the power of the rollover to avris produced while opening brandreth, keep seat to balance.
The accompanying drawing explanation
Fig. 1 is the structural representation of sofa spring assembly in prior art;
Fig. 2 is the structural representation of a kind of specific embodiment of described in the utility model pair of snake spring assembly;
Fig. 3 is the A section enlarged drawing of Fig. 2.
Shown in figure:
11-snake spring, Wooden Batten before the 12-seat, Wooden Batten after the 13-seat, 14-snak link, 15-paper bag steel wire;
21-master snake spring group, 22-reinforces the snake spring, the 23-bending angle, 24-adds flat nail.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
As shown in Figure 2, two snake spring assemblies for the sofa seat frame described in the utility model comprise main snake spring group 21, reinforce snake spring 22 and paper bag steel wire 15, described main snake spring group 21 comprises at least two the snake springs 11 of parallel arrangement in seat frame, two side snake springs 11 that wherein are positioned at avris are provided with reinforces spring 22, be the two snake spring structures of cucurbit serial type, described paper bag steel wire 15 is arranged between the snake spring 11 of main snake spring group 21, prevents from relatively rocking.
Described snake spring 11 band angles, the bending angle 23 of snake spring 11 is connected with Wooden Batten after seat 13.
Described reinforcing snake spring 22 is fixing by adding flat nail 24 with snake spring 11.
As shown in Figure 3, described paper bag steel wire 15, snake spring 11 and reinforcing snake spring 22 intersections, paper bag steel wire 15 is fixedly connected with by adding flat nail 24 with snake spring 11, reinforces snake spring 22 and is not fixedly connected with snake spring 11 at this place.
It is to be noted, all the reinforcing spring can be set on all snake springs in main snake spring group, and can the reinforcing spring be set the part position on the snake spring, reinforcing spring can subsection setup on the snake spring, and above scheme all belongs to the scope that technical solutions of the utility model contain.
