BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a connection lock.

Description of the Prior Art

In the modern society, the living quality is improving, and people lead a quick and busy life, so people have great demand for getting information instantly. Portable 3C products like laptops play an important role in everyday life and workplace, but this type of 3C products may be easily stolen because they are valuable, light and portable. To prevent a laptop from being stolen, an anti-theft chain for a laptop is provided, one of two ends thereof is for being locked with an anti-theft hole of the laptop, the anti-theft chain entangles on a desk leg to prevent detachment. When a user wants to unlock the anti-theft chain, s/he needs to use a key to plug into a lock so as to pull a locking member out from the anti-theft hole. This type of anti-theft chain for a laptop is disclosed in TWM390584. However, when the user wants to use the anti-theft chain for a laptop, s/he has to entangle the anti-theft chain on the desk leg, and the entangling process is complex. In addition, the size of the conventional anti-theft chain is larger because of the key hole thereof, so it is inconvenient to store or carry the anti-theft chain around.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.

SUMMARY OF THE INVENTION

The major object of the present invention is to provide a connection lock, which can effectively prevent 3C products from being stolen, and the connection lock has a simple structure and is easy to operate.

To achieve the above and other objects, a connection lock is provided, including a shell body, a driving assembly, a lock device, an actuating member, a first elastic member and an engaging assembly. The driving assembly is disposed to the shell body and is movable to be in a first position or a second position, and the driving assembly further has a restricting portion. The lock device is disposed to the shell body, the lock device includes a lock member, the lock member is movable relative to the shell body to be in an unlocked position or a locked position, and the lock member has a tendency to move toward the locked position. The actuating member is slidably disposed in the shell body. The first elastic member is disposed in the shell body and abuts against one of the actuating member and the driving assembly to bias the driving assembly in a direction toward the first position. The engaging assembly is disposed in the shell body and is movable to be in a released position or an engaged position, and the engaging assembly is configured to be inserted into an anti-theft hole of an object. When the driving assembly is in the first position, the engaging assembly is in the released position and non-engageable against an edge of the anti-theft hole, the lock member is in the unlocked position and non-engageable against the restricting portion, and the driving assembly is freely movable toward the second position; when the driving assembly moves to the second position, the lock member moves to the locked position and is engaged with the restricting portion, the actuating member is driven by the driving assembly, the engaging assembly is actuated by the actuating member to move to the engaged position, and the engaging assembly is engaged with the edge of the anti-theft hole.

The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment(s) in accordance with the present invention.
