Lock capable of being quickly opened

Abstract

The invention provides a lock capable of being quickly opened. The lock comprises a double-blade thumbing wheel, a latch bolt, a latch bolt transmission mechanism, a deadbolt, a deadbolt transmissionmechanism and a lock shell. The double-blade thumbing wheel is rotationally connected into the lock shell. A first protruding thumbing bolt and a second protruding thumbing bolt are arranged on the outer edge of the double-blade thumbing wheel. The first thumbing bolt is suitable for rotating and thumbing the deadbolt transmission mechanism. The deadbolt transmission mechanism is in transmission connection with the deadbolt. The deadbolt transmission mechanism is used for converting the rotating movement of the first thumbing bolt into the linear movement of the deadbolt. The second thumbing bolt is suitable for rotating and thumbing the latch bolt transmission mechanism. The latch bolt transmission mechanism is in transmission connection with the latch bolt. The latch bolt transmission mechanism is used for converting the rotating movement of the second thumbing bolt into the linear movement of the latch bolt. When the first thumbing bolt is disengaged from the latch bolt transmissionmechanism, the second thumbing bolt starts to abut against the latch bolt transmission mechanism. The double-blade thumbing wheel does not need to do transition movement between driving the latch bolt and driving the deadbolt, that is, no interval-delay operation exists when the twice-locked lock is opened, and unlocking time is saved.

Description

technical field [0001] The invention relates to the field of locks, in particular to a fast unlocking lock. Background technique [0002] Existing door locks, including electric intelligent locksets, are generally equipped with two dead bolts, the oblique bolt and the square bolt. Among them, the oblique tongue is used as the first lock, and the square tongue is used as the second lock (often used for reverse locking) to jointly ensure the safety performance of the door lock. [0003] Regarding the method of driving the expansion and contraction of the oblique tongue and the square tongue, the commonly used structure is as follows: a circular dial is installed inside the lock, and the circular dial, the oblique tongue and the square tongue are respectively transmitted through different transmission mechanisms. . More specifically, the movement of the circular thumb wheel will drive the bolt to expand and contract through the transmission of the bolt transmission mechanism ...

AI Technical Summary

Problems solved by technology

[0005] The defect of this structure is: there is only one tongue on the circular dial, and after driving the tongue, the tongue needs to continue to rotate for a certain distance before it can reach the transmission mechanism of the square tongue and make the square tongue move.

Therefore, there is an interval delay in the whole set of action processes, which makes the speed of unlocking and locking relatively slow, and the efficiency is not high, which greatly affects the user experience

In addition, the single toggle tongue needs to toggle the two transmission mechanisms separately, which causes a large loss to it and limits the service life of the lock.
