Double locking structure of Japanese style air coupler

The double locking structure usually consists of two parts: one is the basic thread locking mechanism, and the other is an additional clip or mechanical locking device. This design greatly enhances the connection strength and sealing performance of the joint through the combined effect of two different locking methods.
Thread locking mechanism
Precision thread design: The thread design of Japanese style air couplers usually adopts high-precision processing technology to ensure that the parameters such as thread profile, pitch and tolerance meet strict standards. This design not only ensures the tightness of the connection, but also enables the thread to generate sufficient friction during the tightening process to prevent the joint from loosening.
Torque control: During the tightening process, tools such as torque wrenches are usually used to accurately control the tightening torque. This ensures that the thread is locked to the appropriate tightness, neither too tight to cause damage to the joint, nor too loose to cause leakage.
Clip or mechanical locking device
Clip locking: Some Japanese style air couplers have a clip locking device on the basis of thread locking. This device is usually located on the outside of the joint and can be quickly locked and unlocked by manual or tool operation. The design of the snap-on locking device is simple and effective, and can further increase the connection strength of the joint on the basis of thread locking.
Mechanical locking: In addition to snap-on locking, some Japanese air joints use mechanical locking devices, such as spring pins, ball rings, etc. These devices automatically lock when the joint is connected to prevent the joint from accidentally falling off due to external force.
Advantages of the double locking structure
Enhanced connection strength: The double locking structure greatly enhances the connection strength of the joint through the combined effect of two different locking methods. Even if one of the locking methods fails, the other method can still maintain a stable connection of the joint.
Improved sealing performance: The double locking structure also helps to improve the sealing performance of the joint. By ensuring a tight connection of the joint, the risk of gas leakage is reduced, thereby improving the safety and stability of the entire pneumatic system.
Adapt to harsh working conditions: The double locking structure of the Japanese air joint enables it to adapt to harsh working conditions such as high pressure, high vibration or impact. This design ensures that the joint can still maintain a stable connection and reliable sealing performance under these harsh conditions.
