A zipper lock is a common locking device typically found on luggage, utilizing metal zipper sliders as locking elements and a series of mechanisms for the locking function.They are commonly used for sealing various items such as luggage, bags, handbags, wallets, and more. Zipper locks are often used to protect the security of internal items while providing a convenient way to open and close sealed items. The design of this sealing device allows users to easily open and close the sealed items while maintaining the security and integrity of the contents.

If you are a product manufacturer, considerations on how to utilize zipper locks and the types of locks to use are taken into account during product design. However, in the past, some products did not come with built-in locks, such as luggage from 30 years ago. Users often had to purchase combination locks separately and attach them to the zipper heads to ensure the security of their assets.

There are several different types of zipper locks, primarily distinguished by their usage and functionality. Here are some common types:

1. Standard Zipper Lock: This is the most basic type of zipper lock, typically formed by two zipper chains interlocking with each other. They are commonly used for items such as luggage, backpacks, handbags, and provide basic opening and closing functionality.

2. Combination Zipper Lock: This type of zipper lock allows users to set a specific numerical code to unlock it. Users can set their personal code by rotating the number dial on the lock, ensuring that only those who know the code can open the zipper. This type of lock is often used for luggage and bags that require higher security.

3. Dual Core Zipper Lock: This type of zipper lock is designed with two independent locking mechanisms—one controlled by the user and the other by security personnel (e.g., airport security). This design provides a convenient way for security personnel to open the zipper when needed while protecting the security of the contents inside.

4. High-Security Zipper Lock: This type of zipper lock is designed with a more complex locking mechanism, often including reinforced metal or special materials to enhance durability. These locks are commonly used for items requiring high security, such as valuable luggage or confidential documents.

These are just some common types of zipper locks, and there are many other variations and innovative types based on different usage scenarios and requirements. Overall, as a multifunctional sealing device, zipper locks have become an indispensable part of our daily lives. Their wide range of applications and diverse functionalities make them an essential sealing solution across various industries, providing us with added convenience and security in our lives.
