Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
As illustrated, a kind of latch bolt trigger mechanism, including lock body 19, latch bolt supporting plate 41, check plate are provided with lock body 19
16th, guide finger is fixed with release board 43, release board back-moving spring 59, locking plate 18 and locking plate back-moving spring 58, lock body 19
22nd, guide pillar 217, latch bolt supporting plate 41 is set in the bottom of guide finger 22 and slides laterally cooperation with it, and check plate 16, which is set in, leads
Coordinate to the top of pin 22 and with its longitudinal sliding motion, release board 43 is riveted on the upper of latch bolt supporting plate 41 and can rotated about, latch bolt
It is provided with supporting plate 41 on spring carrier arm 411 and breach feature 412, lock body 19 and is provided with spring carrier arm 191, spring carrier arm 411
It is linked between spring carrier arm 191 on latch bolt back-moving spring 10, release board 43 and is provided with spring carrier arm 432 and head bending spy
431 are levied, one end of release board back-moving spring 59 is not at breach feature 412, and the other end of release board back-moving spring 59 is set in
On spring carrier arm 432, locking plate 18 is riveted on the bottom of check plate 16 and can rotated about, and locking plate 18 is located at release board 43
It is provided with spring carrier arm 181, sawtooth features 182 and arc notch feature 183, check plate 16 and sets on top, locking plate 18
There is spring hanging head 161, one end of locking plate back-moving spring 58 is not at spring hanging head 181, the other end of locking plate back-moving spring
Not on spring carrier arm 161, head bending feature 431 coordinates with the activity of sawtooth features 182, and arc notch feature 183 is resisted against
On guide pillar 217, sawtooth features 182 include multistage and set as plate engagement is released so as to trigger on the sawtooth of separation, check plate 16
Limited location is oriented to skewed slot 162, spacing to be oriented to guide part 1621 and limiting section 1622 that skewed slot 162 includes being connected, spacing guiding
