Description

  The present invention relates to a structural improvement of a locking device for automobiles and motorcycles, and in particular, it does not automatically unlock even if it is hit, and a shield is provided at the front end, so that the internal arrangement can be seen or destroyed from the outside. Difficult, the lock pin type structure is adopted inside, there are multiple combinations of lock device locking and unlocking, no error gap due to wear even with long-term use, alignment at unlocking It relates to a locking device that can perform smoothly.

  Locking devices are widely used in daily life, and are used, for example, at the entrance of a house or a safe, and there are a dozen or so items locked in one household. A common locking device includes a lock head into which a lock bolt is inserted, and an elastic latch bolt is provided in the lock head to latch the inserted lock bolt. The latch is pressed by a plurality of lock pieces by a spring. If the position is limited by the engine to be aligned and the key is not aligned, the latch bolt cannot be pushed smoothly to unlock.

In addition, there are various types of locking devices with different shapes and functions depending on the application. For example, a locking device for a traffic tool such as an automobile, a motorcycle, etc. There are handle locks and shift locks, and even though these lock devices have different appearance modeling, the internal designs are all as described above, and thus have the following disadvantages in use.
1. The internal design depends on the locking by the lock piece, and if it is used for a long time, it will be worn out and an error gap will be generated, making it difficult to align at the time of unlocking, and it will not be possible to unlock smoothly at one time.
2. Most of the latch bolts depend on the pressure of the spring, and if the lock bolt is pulled outward and the lock head is struck, the latch bolt loses its effect and the lock device is unlocked, so that the prying prevention effect is low.
