Description
Technical field
The invention is related to a kind of from trigger-type theftproof lock technical field, especially a kind of latch bolt fixed point trigger device.
Background technique
Existing currently on the market to spring back barb (or rebound is stepless) triggering from triggering theftproof lock, one for collision bead type, one is
Inclined tongue type springs back barb (or rebound is stepless) triggering, and two ways has the following disadvantages and risk.
1, no matter collision bead or inclined tongue type triggering, before there is knocking door case, by intentionally or accidentally triggering cause locking bolt and
Universe rod stretches out lock housing (locking), at this moment if continuing to close the door, causes the shock of locking bolt and doorframe, produces a thundering noise,
Even damage locking bolt and doorframe.
2, collision bead type triggers the theftproof lock of locking function certainly, harsher to the pitch requirements of crack between a door and its frame, past when crack between a door and its frame is larger
Past to cause that locking bolt locking is triggered, door can be pulled open directly, and there are safe antitheft risks.
Although 3, the theftproof lock of inclined tongue type rebound barb from triggering locking function requires meeting lower door gap, although
Latch bolt can lock, but can equally have the case where king bolt can not lock and exist.
Although 4, inclined tongue type springs back the stepless theftproof lock from triggering locking function and door gap requirement is greatly reduced, meeting
There are false triggering presence.
5, latch bolt not only has the function of triggering the locking of other locking bolts as from a critical component for triggering theftproof lock,
It is also equipped with basic lock point function, but the intensity of latch bolt currently on the market is most of all poor, latch bolt is small, latch bolt and internal
Intensity between supporting plate or connecting rod is insufficient, and material is poor, easily causes latch bolt stuck in frame hole, leads to not open the door.
Summary of the invention

(31) top and its spring coil center are set on the pin (29), a spring pin is not in the spring carrier arm
(283) on, another spring pin not on the spring carrier arm (313), the trigger board (31) is in the trigger board
Under the action of reset spring (30), the round end (312) then resists the end of the square bar (132) always and slides with it
Cooperate, be provided with pilot hole (061), pilot hole (062), groove (063) and driver slot (064) on the locking plate (06),
The pilot hole (061) of the locking plate (06) is set on the guide post (462) and is slidably matched with it, the guiding
Described in hole (062) is set on the guide post (461) and is slidably matched with it, the driver slot (064) is then set in
It is slidably matched on pin (214) and with it, pin (351) is provided on the synthetic position limiting plate (34), under unlocking condition
The pin (351) is stuck in the groove (063) on the locking plate (06), in the above-described state the pin
(351) it is separated with the groove (063), the latch bolt (26), the latch bolt bracket (27) are all made of stainless steel one
Change precision casting technology molding, improves anti-impact force and service life.
The course of work of the invention is as follows: as at closing time, latch bolt 26 collides doorframe stress, and compression and back is locked to the right under Fig. 2 state
During in shell 44, triggering tongue 13 is moved synchronously with latch bolt 26, and trigger board 31 and trigger board supporting plate 28 do not occur relatively at this time
Rotation, i.e., pin 214 is constant relative to the position of shoulder pivot pin 49, so that the locking plate 06 to link with pin 214 also remains stationary,
As long as i.e. latch bolt 26 does not misplace with triggering tongue 13, pin 351 would not be detached from groove 063, after door-closing in-place, trigger tongue
13 are blocked by the corresponding metal plate of doorframe, and latch bolt 26 is stretched out under the action of latch bolt reset spring 07 in the corresponding aperture of insertion doorframe,
At this point, the limiting slot 273 of latch bolt bracket 27 drives trigger board supporting plate 28 to rotate counterclockwise around shoulder pivot pin 49, and trigger tongue 13 not
Dynamic, this causes the position of the round end 312 of trigger board 31 in the horizontal direction constant, and pin 29 drags trigger board 31 around round end 312
Center rotate counterclockwise, moved downward so that pin 214 drags locking plate 06, and then groove 063 is separated with pin 351,
Reach the condition of triggering locking.
Under Fig. 1 state, when with hand-drive pulling axis being unlocked, the drive surface 275 on latch bolt bracket 27 is by thrust, entirely
Latch bolt bracket assembly moves right, and limiting slot 273 then drives trigger board supporting plate 28 to rotate counterclockwise around shoulder pivot pin 49, due to touching
The collective effect that tongue 13 is stopped by 30 tension of trigger board reset spring and doorframe metal plate at this time is sent out, thus it is still motionless, namely touching
It is constant to send out the position of the round end 312 of plate 31 in the horizontal direction, pin 29 drags trigger board 31 and does up time around the center of round end 312
Needle rotation, then pin 214 pushes locking plate 06 to move right, and so simultaneously, pin 351 is with synthetic position limiting plate 34 corresponding outer
Extreme position is moved upward under power effect, and then groove 063 blocks pin 351 again, i.e. synthetic position limiting plate 34 is locked up, such as
Fig. 3 is shown in hand unlocking ultimate position;Then it pushes or pulls on enabling, unclamp handle, latch bolt bracket 27 is made in latch bolt reset spring 07
With lower stretching lock body, finally it is restored to such as the position Fig. 2.
The above, only specific embodiments of the present invention, not make limitation in any form to the present invention, for
For those skilled in the art, under the premise of not departing from technical solution of the present invention, make it is several it is simple modification,
Replacement, modification, each fall within protection scope of the present invention.
