Choosing a buffered hydraulic hinge

Hinge manufacturers teach you to choose the buffer hydraulic hinge

The buffer hydraulic hinge is designed to provide a hydraulic buffer hinge that utilizes the cushioning properties of the liquid and the cushioning effect. The new type includes a support, a door box, a buffer, a connecting block, a connecting rod and a torsion spring. One end of the buffer is hinged on the support; the center of the connecting block is hinged on the support, one side is hinged to the door box, and the other side is connected to the buffer. The piston rod is hinged; the connecting block, the connecting rod, the bearing and the door box form a four-bar linkage mechanism; the buffer comprises a piston rod, a casing and a piston, and the piston has a through hole and a hole, and the piston rod drives the piston to move When the liquid passes through the through hole, it can flow from one side to the other side, and then acts as a buffer.

　　With the addition of users, the number of producers is constantly increasing. Under the tide of the economy of the shopping malls, the shoddy is constantly appearing. Many customers have said that they will soon have no hydraulic function after they have used it. Several times the price of the buffer hydraulic hinge has been used in less than a few months and is no different from the ordinary hinge , how can it not be sad? Even the decoration user decided not to have this hinge in the future. This situation is a bit like the alloy hinges of a few years ago. The hinges made of scrap have been broken at the time of the screws, which made the loyal drag chain customers of many alloy hinges turn a blind eye to the alloy hinges and cast iron hinges. After the crack, the alloy hinge mall is shrinking. Therefore, we also say to the producers who produce buffer hydraulic hinges. Don't hurt the customer's heart for the momentary profit. In the age of information asymmetry, the customer can't distinguish the quality, the manufacturer has to take up. Responsibility for quality, in the end, will achieve a win-win situation between the mall and the profit.

　　Because the hydraulic pressure is good or bad, the seal of the piston is not good, so there is no way for the top chain customer to distinguish it in a short period of time. To choose a good quality buffer hydraulic hinge:

　　1. Appearance, products produced by mature manufacturers will pay more attention to the appearance. It will be better treated on the line and on the surface. Except for the general scratching, there is no deep scratch marks. This is The technical advantages of the strength of the manufacturers.

　　2, the speed of closing the door is even, carefully pay attention to whether the buffer hydraulic hinge is open and closed with a card feel, if you hear a strange sound, or the speed difference is too big, be careful that the hydraulic cylinder has a different choice.

　　3, anti-rust, salt spray test can be seen its anti-rust ability, after 48 hours in general, there are rare cases of rust.
