Description
Technical Field
The utility model belongs to the technical field of locks, and particularly relates to a self-resetting interlock with an unlocking and retaining function.
Background
In the lockset industry, along with the progress of technology and the increasing demands of people for safety and convenience, the design and manufacture of locksets have also undergone remarkable development. However, although the existing locks make a long progress in terms of anti-picking and anti-drilling safety performance, a certain technical bottleneck still exists in terms of user experience, especially concerning the problem of "automatic lock-back" or "false unlock".
Traditional lockset generally adopts spring mechanism to drive spring bolt in order to realize the function of locking. This design has advantages in terms of simplifying the lock structure and reducing the manufacturing cost, but at the same time brings a significant problem, namely the "automatic lock-back" phenomenon. When a user tries to unlock the lock, if the restoring force of the spring cannot be completely overcome or the external force is suddenly lost in the unlocking process, the lock tongue can be quickly restored under the action of the spring, so that the lock appears to be unlocked, and the lock is still in a locked state, namely, the lock is in a so-called false unlocking state.
The phenomenon of false unlocking brings great inconvenience to users, and repeated attempts are needed to confirm whether the lockset is truly opened. In order to solve the above problems, some improved locks have been developed in the market, such as reducing the occurrence of "false unlocking" by adding an unlocking confirmation mechanism, optimizing the mechanical design of the spring, etc., but these solutions often have the drawbacks of complex structure, high manufacturing cost, easy damage, etc., and are difficult to be popularized and popularized comprehensively.
