technical field

The utility model relates to the technical field of lock tongues, in particular to a safety tongue structure, further relates to a lock tongue mechanism including the safety tongue structure, and relates to a door including the lock tongue mechanism.

Background technique

The deadbolt is usually used in the field of door locks and is a commonly used structure for opening and closing doors.

There are mainly three kinds of deadbolts in the field of door locks, one is oblique deadbolt, one is square deadbolt, and the other is safety bolt. Among them, the oblique lock tongue is usually used in conjunction with the door handle. When the user presses the door handle, the oblique lock tongue will retract inward relative to the substrate, so that the door handle can be buckled after aligning with the gusset plate and then releasing the door handle. It may be convenient to retract the oblique latch inwardly. The other is the square lock tongue. The square lock tongue is usually used with the key. When the door is closed, the key is driven by the square lock tongue to push out and buckle the gusset plate, so as to further lock and withstand the impact of greater force. , to achieve effective anti-theft function. There is also a safety tongue, which is used for further locking and anti-theft.

The flip-up safety tongue is one of the safety tongues, which can be locked with the gusset plate without the need to push out the safety tongue through other rotations such as a rotating mechanism.

However, most of the flip safety tongue structures on the market are designed in the form of connecting rods, which are complex in structure and difficult to install, and the connecting rods are easily deformed during use, resulting in structural failure.

Therefore, how to solve the above technical problems is one of the research directions for those skilled in the art.
