คุณรู้ฟังก์ชั่นของส่วนประกอบจัดการกระเป๋าเดินทางหรือไม่? โดยเฉพาะ, luggage handles contain these core parts: an inner tube, an outer tube, a piston/connector, and a locking mechanism. These parts let users extend, retract, and pull the handle smoothly. So how do the different components work? Let’s learn about how luggage handle components function together.
Inner Tube
The inner tube is nested in the outer tube and is the telescopic body of the tie rod. Sliding adjusts the length of the telescopic handle. This is to adapt to the lifting and dragging posture of different users. At the same time, user-applied force travels through the inner tube. This moves the suitcase.
Outer Tube
As the main supporting frame of the telescopic handle, manufacturers usually fix it to the box. It provides a sliding track and force fulcrum for the inner tube. And the outer tube contains locking components such as marbles and springs. This protects them from external impact so that the locking components can work normally.
Piston & Linkage
Piston & Linkage mainly plays the role of power transmission and automatic rebound. It can convert the pressing action of the telescopic handle button into the radial displacement of the marble to achieve unlocking. At the same time, the spring preload device pushes the lever out automatically after pressing the button. ดังนั้น, the quality of the spring also plays a crucial role, which determines the reset and rebound of the spring.
Locking Mechanism
The locking mechanism of the suitcase pull handle mainly relies on the marble. The marble sits in the groove of the inner tube to achieve mechanical locking. And the “lock-unlock” state switches through radial movement.
In the locked state, the spring pushes the marble into the groove of the inner tube, and the tube wall squeezes the marble to generate static friction. In the unlocked state, just press the button to drive the suitcase handle to press the marble back and release it back to the inner tube after it is released from the groove.
Luggage Handle Components Function Sheet:
| Luggage Components | Synergy |
| Inner and outer tubes | Manufacturers compose the pull rod of one or more inner tubes and an outer tube, and the inner tube can slide and retract relative to the outer tube. |
| Piston or connector | A piston, a spring, or other connecting devices connect the inner tube and the outer tube to realize the telescopic function of the pull rod. |
| Locking mechanism | A button, a wrench, or a similar device can unlock or lock the pull rod to control its extension and retraction state. With this structure, users can extend and retract the pull rod as needed. And making it convenient for users to use it in different scenarios. |
