Spinning lock development status and outline

Today, with the development of security doors, do you know exactly what your locks are? Did you remember that once you used the safe lock, did you remember that there was a pinball lock that contributed to your privacy and property protection today? Let's take a look at the tumbler lock below.

Bullet Lock Overview Pin Tumbler Lock, also known as pin lock, bead lock, lock spring lock or pin lock, is one of the most common lock structures. The principle is to use multiple cylindrical parts of different heights (called lock springs, marbles or beads) to lock the lock cylinder. When the correct key is placed, the lock springs are pushed to the same height and the lock cylinder is released.

In 1848, American Yale-Linnas invented a pin lock with a cylindrical pin. At present, this kind of structure is commonly used in various kinds of locks in the world. There are new developments in the structure of modern marble locks, such as two-way, three-way, four-way marbles, and many structures such as mother marbles, as well as flat, double-faced, multi-faced, double-row, double-row, multi-row, multi-surface marble structures and composite marble structures. , thereby greatly improving the security of the lock, so that the number of locks from the original 2,500 kinds of "direction", "face" change to reach a million species.

Structure 1. Cylinder: A cylindrical copper cylinder that can be locked or opened while turning. The lock cylinder is divided into the inner lock cylinder and the outer lock cylinder, and the inner lock cylinder is where you insert the key.

2. Billiards: Copper marbles are divided into inner and outer marbles. They are cylinders of different lengths and are mounted in round holes in the inner and outer cylinders. A lock usually has 3--5 sets of marbles.

3. Spring: Installed in the round hole of the outer cylinder. Hold the marbles.

4. Locking tongue: The part that expands and contracts when unlocked. Cylindrical lock cylinder drives the lock when it rotates. The padlock is the locking nose.

5. Key: No need to introduce, there are different heights of sawtooth corresponding to different lengths of marbles.

Spinning lock development status The spin lock has been available for more than 150 years and is still widely used. It is a relatively common type of lock on the market. However, due to the extensive use of pinball lock technology, the drawbacks of pinball locks have become more and more obvious, mainly in the following three aspects:

1. The ends of the marbles are exposed and the working stroke is short. The marbles can be directly touched by foreign objects (wire hooks, etc.) and can easily be opened by technology.

2. Unless the lock key can enter the lock core, it is easy to cause the key to open each other and the key teeth to open each other. Their own keys can be locked into other people's houses, and some can even be unlocked by others.

3. The keys can be freely prepared. People with key can be found everywhere in the market.

In recent years, the development of new products in the lock manufacturing industry in China has improved both in terms of product technology and product quality. According to our investigation of new products developed in the lock industry in the past five years, many companies have developed many new products.
