WIPO Patent Application WO/2019/114006
Kind Code:
A1
Abstract:
Disclosed is a lockset for quick escape, relating to the field of locksets, comprising a handle provided on an outer panel and a lock body (100) formed with a safety transmission structure (110) and a lock bolt transmission structure (120), wherein the safety transmission structure (110) comprises a first rotation device (10) and a safety latch (20) in transmission connection, and the lock bolt transmission structure (120) comprises a second rotation device (30) and a lock bolt (40) in a transmission connection; and the handle is fixedly mounted on the second rotation device (30), and the second rotation device (30) is in transmission connection with the first rotation device (10), so that the safety latch (20) and the lock bolt (40) are simultaneously retracted into the lock body (100) when the handle is rotated. The present invention solves the problem of the existing lockset needing to first open the safety latch and then press down the handle to open the lock bolt, resulting in a long unlocking time and delaying the time of rapid escape in an emergency situation.
