Pay attention to the "quality door". What is the mechanical performance of furniture?

Recently, the State Administration of Quality Supervision, Inspection and Quarantine issued the "2009 third batch of product quality national supervision and spot check quality announcement", so that "mechanical performance" such a "very technical content" professional vocabulary, has become the most concerned word in the furniture industry. According to the results of the announcement, among the 114 unqualified furniture products found in this spot check, 68 kinds of unqualified mechanical properties, accounting for more than half of the unqualified products, became the first "quality door" of the home industry in the beginning of 2010. "event. So what is the mechanical properties? How much does it affect the use of furniture? How should consumers check when choosing furniture? To this end, the reporter interviewed Li Bo, director of the Light Industry Center of the Sichuan Provincial Quality Supervision Institute. Li Bo told reporters that mechanical properties refer to the mechanical characteristics of furniture materials under various environments, subjected to various applied loads, such as compression, continuous loading, bending, torsion, durability, impact, etc., mechanical properties are not up to standard, Will affect the life of the furniture and the safety of use. The main object of this AQSIQ spot check is the wooden bedside table. The main detection method is to pull the drawer of the bedside table out 2/3, and after placing 30 kg of weight inside, the whole drawer can not be inclined. Li Bo believes that this test method tests the limit of the weight of the drawer, which is generally not encountered in normal household use. Therefore, the sampling results only indicate that the structural design of the bedside table is not perfect, not the product material. Therefore, consumption does not have to talk about tiger color change, and is too worried about the quality of furniture. When consumers choose furniture, they should consider the safety of the furniture and the actual conditions of use. From the point of view of safety, tall furniture such as large wardrobes, bookcases, etc. are more dangerous than low-sized furniture, so special attention should be paid to the choice; from the conditions of use, the weight of furniture such as wardrobes and bedside tables is neither It may be very large, and the built-in objects are not likely to be many, and the possibility of tipping is not great. When selecting, first of all, we should pay attention to whether the proportion of furniture is coordinated. Try not to choose furniture with too long, wide and high proportions. For example, some chairs are designed with a backrest that is too large and the base is too small. People sit on it as if it were moving. Large, easy to tip over; secondly, should pay attention to the furniture material, it is best to use solid wood, the thickness should match the function of use. In general, the regular manufacturers are basically qualified in material selection; finally, pay attention to the details of the design. For example, the design of the drawer slide is strong, the inclination of the backrest of the chair is reasonable, and the like.

The supporting tube stand is also called the branch pipe seat, saddle seat and saddle type pipe joint. It is mainly used for reinforcing pipe fittings of branch pipe connection, instead of using different diameter three - way, reinforcing plate and strengthening pipe section. It has the advantages of safety, reliability, lower cost, simple construction, improvement of medium channel, series standardization, convenient design and so on, especially in high pressure, high temperature, large diameter and thick wall pipe. It is widely used instead of the traditional branch connection method.

The main body is made of high quality forgings, and the material is the same as that of pipeline materials, such as carbon steel, alloy steel, stainless steel and so on. Both the pipe and the head are welded, and the joint of the branch pipe and other pipes, such as the short pipe, the plug and so on, the connection of the instrument and valve, has many types of welding, socket welding, thread and so on.
