Why is the stainless steel door and window connecting rod also called stainless steel friction stay? To understand the reasons, we must first understand what is the connecting rod and the connecting rod system.
In fact, the two (four) connecting rods of stainless steel doors and windows are an application of many connecting rod systems. In order to better understand this system and structure, we use the automobile connecting rod system.
The automobile connecting rod group is composed of connecting rod body, connecting rod big end cap, connecting rod small end bushing, connecting rod big end bearing bush and connecting rod bolt (or screw). The connecting rod body is composed of three parts, and the part connected with the piston pin is called the connecting rod small end; The part connected with the crankshaft is called the big end of the connecting rod, and the rod connecting the small end and the big end is called the connecting rod body.
Through the introduction of automobile connecting rod, we can more intuitively understand the connecting rod system. In the machine age, as a theoretical tool of mechanical structure, the connecting rod system once became the hottest topic in the mathematical field. The so-called connecting rod system is a mechanical device formed by connecting some rigid small rods with rotating shafts at the end points. After fixing the position of some vertices, the other moving points can draw some interesting tracks; Then such a set of connecting rod system is the stainless steel friction stay or window brace used by most of our doors and windows today, which plays the role of connection, support, fixation and limit in doors and windows.
Therefore, it is not difficult for us to understand that the stainless steel friction stay is the second (fourth) connecting rod of stainless steel doors and windows often said in the industry.
