Description

Key bar structure

The invention relates to a key bar structure, in particular to a key bar structure which can increase the variability of the locking bead unlocking direction, thereby improving the difficulty of unlocking the thief and achieving an effective anti-theft.

According to the lock, the safety of personal life and property is very important. In order to prevent valuable items such as houses, cars and safes from being invaded by thieves, people will install various locks on houses, cars and safes.

There are many types of locks, including a steel ball lock, a combination lock, a rotary disc lock, etc., wherein a lock core structure is mainly provided with a key hole for the key to be inserted and rotated in the lock core, and at least one row is arranged in the axial direction of the lock core. The number of the bead holes is locked, and the locking bead holes are penetrated into the key hole, and the lock core casing is combined with the lock core casing, and at least one row of the locking bead holes are arranged in the axial direction of the lock core casing to match the lock The position of the number of the lock beads is correspondingly communicated, and the elastic member, the first lock bead and the second lock bead are sequentially accommodated in the lock bead hole of the lock core and the lock core casing. Thereby, in the usual time, the locking bead is pushed by the elastic member, and the first locking bead is just locked between the lock core and the lock core casing, so that the lock core cannot be rotated, so as to achieve the purpose of locking, when the key is inserted into the lock core In the keyhole, the password slot design corresponding to the arrangement of the lock beads is used to make the first lock bead fall to the key slot of the key, so that the first lock bead and the second lock bead are located at the intersection The lock core and the lock center are connected to each other to achieve the purpose of rotating the key to turn the lock and unlock.

However, the existing locks have been found in use. Due to the limited change of the existing lock code, only the position and number of the lock beads are changed. Therefore, the thief can easily use the unlocking tool to insert the lock key hole and then easily unlock. The user's property and other losses are caused. Therefore, if a key and a lock that are different from the existing password design can be developed, the complexity and variability of the password arrangement can be improved, and the difficulty of unlocking can be increased, so that the thief cannot easily unlock the lock. Anti-theft to protect personal life and property security purposes.

The reason is that the inventor has in view of the fact that the existing key and lock cipher design cannot break through the defects of the existing thief, and it is easy to be unlocked by the thief. It is supported by many years of manufacturing and design experience and knowledge in related fields. Thinking, research and development of the present invention.

The invention relates to a key bar structure, and the main purpose thereof is to provide a key bar structure capable of increasing the variability of the locking bead unlocking direction, thereby improving the difficulty of unlocking the thief and achieving an effective anti-theft.

In order to achieve the above-mentioned implementation, the present inventors have developed a key stem structure, which is mainly provided with a rod body, and at least one long slot type first tip hole is penetrated in a radial side of the rod body, and The rod body has at least one second tip hole on the other side of the rod, and the first tip hole and the second tip hole are correspondingly communicated with each other, and a jack is axially inserted at a center of one end portion of the rod body, and The jack is connected to the first tip hole and the second tip hole, and the first tip is disposed in each of the at least one first hole, and the second tip is disposed in each of the at least one second hole a plant tip, and a first trough-shaped first notch is recessed on one side of the first plant tip, and a second trough-shaped second notch is recessed on one side of the second plant tip, and the first plant tip is The first notch is engaged with the second notch of the second plant tip, and at least one of the insertion holes is arranged to insert the insertion hole into the insertion hole of the rod body, and the first plant tip is opposite The first gap is on the other side toward the transplanter, Corresponding to the transplanting, the one end of the plug is abutted against the side corresponding to the first shoot tip to fix the joint state of the first shoot tip and the second shoot tip.
