What is the principle of heavy duty latch pin?

The principle of industrial heavy duty spring pin is to use the elastic deformation and force of the spring to realize the connection and fixation of parts. Specifically,

When the pin is inserted into the hole, the spring is under pressure and the elastic deformation occurs. This pressure causes the spring to produce an outward force that creates friction between the pin and the hole wall, thus connecting and fixing it. The elastic force of the spring enables the heavy spring pin to withstand a certain load and vibration to maintain the stability of the connection.

The pin pin rod is equipped with a spring, through the action of the spring force, can make the pin automatically back to self-lock, to solve the original linear moving pin opening and closing difficulties, can not self-lock problem. When the external force acts on the pin, overcome the elastic force of the spring to pull out the pin rod from the jack; when the external force disappears, the spring returns to its original state and pushes the pin rod into the jack to realize connection and locking.
