Detailed description of the classification and composition of the internal structure of the fabric sofa

At present, fabric sofas on the market are roughly classified into these types in terms of structural technology:

1. Slab-wood structure - use cheap wood to make beams and erect supports, combined with multi-layer composite panels to form structural skeletons by nailing. The structure of the structure is low in cost, simple in fabrication, convenient in forming, and high in manufacturing efficiency, and is a widely used process structure. Disadvantages: The multi-layer composite sheet has high formaldehyde content, which is easy to cause pollution and a large amount of odor. The solidity is generally deformed by moisture and has a short service life. When choosing, pay attention to shaking the sofa to check the stability of the structure, open the bottom zipper and breathe deeply to smell if there is any smell, and then sit down and feel the impulse reaction.

2, solid wood structure - due to the shortage of wood resources, the hardwood used for furniture structure is more rare, coupled with the dry processing of hard wood requires high technical means, through the 榫卯 connection. Therefore, the fabric sofa with real solid wood structure is quite expensive, and it is necessary to ask about the variety of solid wood and the technical means of the factory. Such structural sofas are quite rare.

3, all-steel welded structure - ordinary standard square steel pipe is welded under standard test tools for anti-rust treatment. This kind of process is difficult to form, has long working hours and high technical requirements. Advantages: good structural stability, high strength, good environmental protection and long service life. At present, most European sofas adopt this structure, which is the future development direction of domestic fabric sofas.

Fabric sofa structure dissection:

1. The general sofa is composed of skeleton + sponge + fabric.

2. The skeleton is made of wood and solid wood.

3, the structure of the sofa seat frame by the frame - serpentine spring - elastic - base fabric - sponge - magic cloth finally to the cushion.

4, the structure of the cushion. The cushion is divided into a multi-layer sponge cushion, a sponge cushion, and a spring sponge cushion.

5, sponge, is the main part of the sofa, the key to the quality of the sofa is in the sponge. The quality of a sponge depends on its density. Generally speaking, no one in the sofa now uses a 60-density sponge (and many merchants will tell consumers how high and high the density of my sponge is. Even some say it is 60-density. Is there, sure? One sentence, no. It’s just a flicker.)

No matter what you say, look at the real thing, judge the quality of the sponge and the density, use a finger to gently press it to see its recovery speed, the density is good, it will recover in 3 seconds, the longer the recovery time, The density of the sponge is worse. The worse the density of the sponge, the shorter its life.

4 Stroke Outboard Motor

First, compact design, light weight, easy to carry, gear adopts forward, neutral design, no need to shift, gear is not easy to break.

Second, the height of the hanger can be adjusted freely from 40cm to 55cm, which can meet the needs of ships of different heights.

Third, superior startup performance, easy to start in both winter and summer.

Fourth, fuel saving; The 4-stroke air-cooled engine uses fuel-saving technology to make the gasoline burn thoroughly and convert every drop of gasoline into power, unlike the 2-stroke machine, which has part of the unburned gasoline and oil discharged into the water leading to waste and pollution.

Fifth, durable; The 4-stroke air-cooled engine adopts pressurized circulating oil circuit, so that the bearings and the parts that need lubrication can be lubricated directly. The large throttle runs continuously for more than 20 hours, the power does not attenuate, and the fuel consumption does not increase, and the machine has no abnormal.
