Description

The present invention relates to an 80,000 lock type lock, and more particularly to an 80,000 lock type lock having excellent dustproof and anti-theft effects.

80,000 locks are often used in devices such as vending machines, parking meters, game machines, and coin lockers because of their simple structure, small volume, low production cost, and high anti-theft properties. ..

However, in the conventional 80,000 locks, since the keyhole opening is not provided with a shielding member, all pushpins inside the lock cylinder are partially exposed from the keyhole opening (that is, all inside the lock cylinder). The conventional 80,000 locks have the following drawbacks because the pushpin can be easily seen from the outside through the opening of the keyhole).

First, since the conventional 80,000 locks are prone to moisture and dust, there is a risk that the components such as the push pin inside the lock cylinder may be rusted or clogged, making it impossible to lock and unlock.

Second, the conventional 80,000 locks are less likely to be picked than ordinary cylinder locks, but because the keyhole opening does not have a shielding structure and the lock cylinder push pin can be seen from the outside. If a person trying to unlock illegally takes time for picking work, he / she is more likely to be the victim of theft.

The present invention has been made in view of the drawbacks of the prior art, and has a dust-proof and anti-theft effect that has a lid member that shields the opening of the keyhole, prevents the intrusion of moisture and dust, and prevents unauthorized unlocking. The purpose is to provide an excellent 80,000 lock type lock.

In order to achieve the above object, the present invention is an 80,000 lock type lock having excellent dustproof and anti-theft effects, and includes a tubular lock, a lid member, and a mounting tool.

The first fitting portion is formed on the front side surface of the lid plate portion.
The mounting tool includes a second fitting portion formed in a shape and size that can be fitted to the first fitting portion of the corresponding lid member, and the fitting portion of the second fitting portion and the first fitting portion is fitted. It is characterized in that the mounting tool can rotate integrally with the lid member due to the coupling relationship.

As described above, the advantage of the present invention is that the lid member is installed in the lid plate portion via the male screw portion and screwed into the female screw hole formed inside the annular keyhole of the tubular lock. It is possible to prevent the intrusion of moisture and dust, and it is possible to prevent the components such as the push pin inside the lock cylinder from being rusted or clogged and becoming unable to be locked and unlocked. In addition, since the keyhole is shielded by the lid plate, it is difficult for a person who tries to unlock illegally to reach the keyhole even if he / she tries to pick illegally, so he / she may be the victim of theft. The sex is reduced and the anti-theft property is further improved. Further, since the lid member is attached or detached with the use of the attachment tool, the outer shape of the first fitting portion of the lid member as a pair and the second fitting portion of the attachment tool is special.
