Eccentric wheel in furniture and cabinet industry: also known as eccentric connection matrix, is the most commonly used panel furniture and cabinet production connectors accessories, she and connecting rods, embedded parts into a combination of three-in-one connectors, also known as disassembly connectors, because it can disassemble and assemble furniture at any time and anywhere, this connector is very large Convenient transportation of furniture, door-to-door installation, but also vigorously promote the overall furniture and cabinet industry production.
Working Principle: As the eccentric wheel bottom deviates from the center of the circle radian, when rotating the eccentric wheel, the connecting rod in the radian will be slowly close to the center of the eccentric wheel bottom along the radian, thus tightening the distance between the two plates, so that the connection is fastened, "eccentric connector" hence the name.
Classification
According to the shape of the internal clip can be divided into two kinds: one is a ball, with screw round head; the other is arc, with teeth, with screw square head.

Indicators: The most common is made of zinc alloy by die-casting, its common specifications are 15, is the general specifications of furniture panels, of course, some furniture drawers and other thin plates are used in 12, 10 specifications, and some large-scale public furniture, due to the thickness of the plate, the use of the important demand for height. Due to the lack of domestic furniture hardware standards, there is no general standard in the industry. In terms of the current furniture industry plate specifications, the size of 15 is the most common, the largest use.
A) according to its shape, it can be divided into two types: one is the cross slot eccentric wheel, the other is the cross plus six angle eccentric wheel. (Note: This kind of eccentric wheel can be installed with either cross screwdriver, one-word screwdriver or hexagonal wrench.)
B) according to the shape results, it can be divided into two types: one is an eccentric wheel with external teeth, the other is a toothless eccentric wheel. (Note: the characteristic of the eccentric wheel is that the three in one will be fastened after assembly and no retrogression will occur.

Molecular vacuum pump selection
Molecular vacuum pump molecular vacuum pump is the use of high-speed rotation of the rotor to transfer kinetic energy to gas molecules, so that the directional speed, which is compressed, was driven to the exhaust port after a vacuum pump for drawing off a molecular vacuum pump The gas molecules collide with the high-speed rotor to obtain the momentum and are driven to the outlet of the pump. In the actual product selection, we also need to do the necessary work, only the relevant data, the selection of a more clear understanding in order to filter out the best products. Molecular vacuum pump molecular vacuum pump, you need to note the following: 1, the working pressure of the vacuum pump molecular vacuum equipment should meet the ultimate vacuum and pressure requirements. 2, the correct choice of molecular vacuum pump working point. Each pump has a certain range of working pressure, 3, the molecular vacuum pump in its work pressure, should be able to drain away all the gas generated in the process of vacuum equipment. 4, the correct combination of molecular vacuum pump. Due to the vacuum pump selective suction, therefore, sometimes the choice of a pump can not meet the pumping requirements, the need for several pump combinations, complement each other to meet the pumping requirements. 5, vacuum equipment, oil pollution requirements. If the equipment is strictly required oil-free, should choose a variety of oil-free pumps, such as: water ring pump, molecular sieve adsorption pump, sputtering ion pump, cryogenic pump. 6, to understand the composition of the gas being drawn, the gas containing non-condensable vapor, whether the particles of dust, whether or not corrosive. 7, the molecular vacuum pump out of the oil vapor on the environment how the impact. If the environment does not allow contamination, you can choose oil-free vacuum pump, or the oil vapor to the outside. 8, the price of the vacuum pump, operation and maintenance costs. As China's economy continues to develop, it has a huge market for molecular vacuum pumps. At the same time, it also needs to face enormous challenges. How to make these products more adapted to our economic development and to understand the relevant data is the most fundamental jobs. Related staff can further study related topics, I believe these topics will have a great impact on the development and improvement of such products.
