Description

Tubular lock with depressing latch

The present invention relates to a tubular lock, in particular to a tubular lock that can be used to lock a pivot mechanism and can be switched to open or close in an unlocked state with a pressable lock.

A lock is a device used to prevent important items from being stolen or to prevent specific places from being invaded at night. After continuous improvement since ancient times, various forms and locks with different functions have been developed, and the push-type tubular lock is one of them. For more common locks, generally speaking, push locks are mostly used for clamping mechanisms that move linearly, such as drawers, horizontal sliding doors or horizontal sliding windows, etc., to prevent the drawers or doors and windows from being opened arbitrarily.

Specifically, the push-type tubular lock in the prior art has a lock shaft. When the push lock is in the locked state, the lock shaft protrudes backwards out of the push lock, so that the rear end of the lock shaft is opposite to the lock shaft. The mechanism that can move linearly forms a catch; when the push lock is unlocked with a key, the lock spindle will protrude forward from the push lock, so that the rear end of the lock spindle retracts into the push lock and Release the lock. After that, the user can switch the push lock to the locked state by pressing the lock shaft from the front end of the push lock. That is to say, the push lock only needs a key when unlocking, but not when locking. It can save the action of searching for the key when locking, and can also avoid the problem of increasing the probability of losing the key due to repeatedly taking out the key.

However, as mentioned above, the above-mentioned push-type tubular lock that only needs to use a key when unlocking can only be used for a mechanism that clamps a linear movement, but cannot be used to lock a mechanism that will pivot, such as being mounted on a door frame through a hinge Or push-open doors or push-open windows on window frames. Furthermore, although the above-mentioned push-type tubular lock only needs to use the key when unlocking, it still needs to use the key every time the lock shaft is switched to the locked state, and there is no way to temporarily lock the locked state and the locked state in the unlocked state. Switch between unlocked states, so There are still inconveniences in its use, which need to be further improved.

In view of the aforementioned problems in the prior art, the purpose of the present invention is to provide a tubular lock capable of pressing the latch, which can be used to lock the pivot mechanism and can be switched to open or closed in an unlocked state.
