Abstract
Description
Technical Field
[0001] The utility model relates to the field of deadbolt locks, in particular to a double-lock deadbolt lock. Background Art
[0002] A deadbolt lock is a common lock on the market. The deadbolt, a square or round metal part, can only be retracted or extended by twisting or squeezing. It cannot retract when extended or when subjected to force on its end. It is widely popular for its compact structure and excellent security. However, existing deadbolt locks are typically one-way mortise locks, meaning they only have a keyhole on the outside of the door and a safety knob inside. While this is convenient, someone inside can open the door simply by turning the knob without a key, making it less secure.
[0003] In the existing two-way keyless locks on the market, the inner and outer lock cylinders are usually integrated, which lacks structural rationality. If one of the inner and outer locks has a problem, both the inner and outer lock cylinders need to be replaced, which is costly and inconvenient to replace.
[0004] For this reason, need a kind of double lock deadbolt lock to solve this problem. Utility Model Content
