Recently, as the awareness of crime prevention and security has increased, demand for security devices and marketability have been greatly expanded. With the development of various products, the product maximizes the function and usability of digital door lock, which is generalized. Innovative design was suggested by developing more convenient and trendy products. In general, door locks are equipped with lever-shaped inner and outer handles, which are used to open the handle when rotating. In general, a door-lock having such a structure is disadvantageous in that it is difficult to perform a quick and intuitive operation because the direction in which the door is opened and the direction of the force applied to the handle are different in order to open the door. Therefore, it is a push-pull door lock which is designed to solve this problem more conveniently and simply, and when a force is applied to the inner or outer handle in the direction of opening the door, the door is opened with the lock being released. |
