Description

Bolt lock and key

Technical Field

The utility model relates to a lock, especially with the lock core of terminal surface relative rotation to the tool to lock of bolt mode meshing locking.

Background

The existing mechanical lock mainly comprises a pin tumbler lock and a blade lock with a key slot, because the key slot is difficult to process, the material of the lock core can only use brass with low strength, the existing pin tumbler lock core adopts a shaft core type lock core, which requires that the key slot and a key handle rod are required to be provided, the code positions of pin tumblers are arranged linearly, key teeth are also arranged linearly, the concave-convex angle of the key teeth is required to be less than about 45 degrees to be inserted into the lock core conveniently, so that the length of the grade difference between the longest pin tumbler and the shortest pin tumbler can not be much larger than the diameter of the pin tumbler, the number of pin tumblers and the number of pin tumbler grades are greatly limited, only the number of bits is usually one, and the number. The bolt of the common lock is in a direct insertion mode, so that most of destructive unlocking by thieves is realized by picking the bolt of the door, which proves that the bolt insertion mode which is commonly used at present is very weak.

There is no special lock for locking screws in the market, mainly because the screws are not large, but the traditional mechanical lock is not small, and is not suitable for locking screws. In addition, under the conditions of long-term high load and high vibration, the situation that screws are loosened occurs occasionally, and great potential safety hazards are brought to the safe operation of machine equipment. Based on these problems, there is a need for a bolt lock that can prevent theft and loosening.
