Product Description
The main difference between self-priming and non-self-priming of automobile trunk locking belt lies in its working principle and function:
1. Tailbox lock with self-suction: Tailbox lock with self-suction is usually equipped with a vacuum pump or a vacuum cylinder. The negative pressure generated by the vacuum pump or the vacuum cylinder enables the tailbox lock to automatically absorb and closely fit when it is closed, ensuring good sealing performance of the tailbox. This design can effectively prevent the tail box from accidentally opening due to vibration or bumps during driving, and improve driving safety.
2. Tail box lock without self-priming: The tail box lock without self-priming has no vacuum pump or vacuum cylinder, so it is necessary to close the tail box manually and lock the tail box with a lock. This design is relatively simple, but it needs manual operation by the user, and sometimes it may lead to the risk of accidental opening of the tail box because it is not closed in place or the lock is not firm.
Therefore, the tail box lock with self-priming has the functions of automatic adsorption and close fitting, which improves the sealing and safety of the tail box, but the cost is relatively high; The tailbox lock without self-priming is relatively simple to operate, but it needs manual operation by users, which has certain operational risks. Consumers can choose the appropriate trunk lock type according to their personal needs and budget. When buying or replacing the trunk lock, it is recommended to choose the formal channel to ensure the quality and safety of the product.
