The requirements for locks vary greatly depending on the usage environment and grade of items. Among them, U-shaped locks are also commonly used locks in daily life. So what are the types of U-shaped locks? Let's take a look together below.
1. According to the structure, there are two types of U-shaped locks: double open and single open. After the double opening U-shaped lock is opened, the lock beam and cover plate are separated, and the cover plate needs to be removed before opening; Except for the key that can be opened and closed, the other end of a single lock is a movable connection. Double lock is generally used for glass doors, while single lock is generally used for bicycles, motorcycles, etc.
2. According to the unlocking method, there are regular locks and password locks. Ordinary locks can be opened with a key, password locks can be opened according to the password you set, and password locks are mostly double unlocking.
3. According to packaging, there are two types of single lock beams: with or without packaging and with packaging. Locks without packaging on the lock beam have rough workmanship, with only a coating on the surface. Most of the locks with packaging on the lock beam are wrapped in high-quality rubber, which can prevent scratches and increase the service life of the lock.
4. According to the material classification of lock cylinders, there are copper lock cylinders, stainless steel lock cylinders, and plastic lock cylinders. Copper lock cores are the best and slightly more expensive, with ordinary ones mostly being iron lock cores and the worst being plastic lock cores.
5. According to the length of the U-shaped lock, it can be divided into adjustable and non adjustable. Adjustable locks are suitable for various environments, while non adjustable locks are more suitable for products such as bicycles and electric vehicles, which are relatively fixed.
