Description

Improved door lock

【Technical field】

The utility model relates to a lock, in particular to an improved door lock.

【Background technique】

Locks are widely used in people's lives, and they can lock doors, windows and cabinets to achieve the purpose of anti-theft; and with the development of the times, locks have gradually developed a variety of implementation styles, and provide Different functional advantages.

Generally speaking, the door lock is installed on the side of the door panel, which has a bolt that can be controlled by a knob or key to protrude, and is fastened to a corresponding engaging part on the door frame or other fixed surface, so as to achieve Door locking. The deadbolt has an arc-shaped inlay hole, and the arc-shaped inset hole is used for the insertion rod of a brake mechanism to pass through. The brake mechanism can rotate relative to the housing of the door lock and is pushed by a single spring to obtain An elastic force is used to rotate, and the insert bar slides in the arc-shaped insert hole, so as to move the lock tongue to achieve relative protrusion of the lock tongue.

In actual use, when the deadbolt is not relative to the engaging part, it may protrude from the side of the door panel due to the inadvertent use of the knob or key, causing accidents such as bumps and scratches; and the aforementioned braking The design of the mechanism uses a single spring to push the top to assist the protrusion of the lock tongue, which often makes the braking mechanism under the influence of frictional resistance, and the insert rod slides to the middle of the arc-shaped insert hole of the lock tongue and cannot continue to move. No positively locked position has been reached. In this way, although the bolt can still protrude, once it is resisted by an external force, it will retract by itself, thus causing poor locking effect and reducing its anti-theft effect.

In addition, the door panels or their corresponding door frames currently on the market often do not have certain specifications, so the thickness of the sides varies. When the door lock is installed on the side of the door panel that is too thick or too thin, The protruding length of the lock tongue will not match, making it difficult to be smoothly locked in the engaging part, and it will take a long time for the construction personnel to forcefully apply force to deform the lock tongue or door panel to achieve adjustment, which not only causes great inconvenience, but also And may lead to poor construction quality.

【Content of utility model】

The purpose of this utility model is to provide an improved door lock, which has safety settings, which can prevent the lock bolt from protruding inadvertently and cause danger, and is provided with an elastic element to provide an extra elastic force to ensure the safety of the door lock.
