When running into burst dangerous situation or natural disaster, need energency-unlocking, and a period of time can not find remote-control key or dead battery or motor breaks down, it is accomplished by manually unblanking, general push rod 5 is integrally fixed on latch frame or tooth bar, making motor reversal by lower push-rod, wear and tear electric motor speed reducer gear, and the bolt mechanism of manual clutch can solve this problem.
Emergent operation principle of manually unblanking
Operating position graph of a relation referring to the structure chart of Fig. 1 to Fig. 5 and Fig. 6 a-6c, the operation manually unblanked is as follows: under bolt lock closed state (as shown in Figure 6 a), finger push to the right push rod 5 make manual unlocking frame 4 along slide move right compression the first spring, inside manual unlocking frame 4, the wedge shape shoulder 17 of (the first side surface) inwardly promotes the middle shoulder 15 in the middle part of elastic on-of pin assembly to compress the second spring 16, and elastic on-of pin assembly 14 retraction is exited described lock slots 11 and unlocked described transmission clutch block 8.First spring-compressed to a certain extent after, manual unlocking frame 4 starts to promote latch frame 1 to move right, and is arranged on transmission clutch block on latch frame 1 and installs axle 12 and move right.Meanwhile, tooth bar 2 remains stationary as, and the trundle 18 being inserted in transmission draw-in groove 10 remains stationary as, thus transmission clutch block 8 deflects.After transmission clutch block 8 deflects an angle, trundle 18 departs from from transmission draw-in groove 10, thus realizing latch frame 1 and tooth bar 2 motion separation.Latch frame 1 moves to limit on the right-right-hand limit position and realizes unblanking, and limit on the left position (such as Fig. 6 b) stayed by tooth bar 2.
Smart electronics keeper, after carrying out manual emergency and unblanking, is typically in keeper and recovers also to pass through driven by motor latch frame locking latch after normal electrical controls.Accordingly, it would be desirable to made transmission clutch block keep deflexion attitude before tooth bar 2 moves to limit on the right-right-hand limit position, in order to after tooth bar 2 moves right, trundle 18 can enter transmission draw-in groove 10 smoothly, makes transmission clutch block 8 recover the connection between tooth bar 2.
When transmission clutch block 8 just deflects, the end of elastic on-of pin assembly 14 is contracted in the Part I of transverse holes 7 under the effect of lozenges, end is corresponding to the region between lock slots 11 and the described angle limit groove 27 of transmission clutch block 8, and described angle alignment pin 28 moves towards weakened region from the bottom-right ' locked ' zone of transverse holes of angle locating slot 29 relative to manual unlocking frame.
After transmission clutch block 8 deflection puts in place, the end of elastic on-of pin assembly 14 is corresponding to described angle limit groove 27, and angle alignment pin 28 moves into Part III from weakened region.Along with latch frame 1 motion puts in place, release manual unlocking push rod 5, manual unlocking frame 4 exists relative to latch frame 1 movement tendency to the left under the rebound effect of the first spring 6, the end of elastic on-of pin assembly 14 is in effect long a small distance of end micro stretching of lozenges, This move occurs in a short period of time, therefore, the end of elastic on-of pin assembly 14 snaps in angle limit groove 27 just.Thus, the coordinating of the end of elastic on-of pin assembly 14 and angle limit groove 27, transmission clutch block 8 coordinating and the supported at three point (as shown in Figure 7b) cooperatively formed along straight line of Part III of angle alignment pin 28 and transverse holes of axle 12 and axis hole 9 is installed.In the absence of external forces, transmission clutch block 8 keeps this deflection angle, and its active force is possible to prevent to turn round owing to lock body shakes transmission clutch block 8.Now, transmission clutch block, latch frame and manual unlocking frame rest on right limit position.
When motor resume work band carry-over bar move right time, the trundle 18 of tooth bar enters the transmission draw-in groove 10 towards upper left side opening, and promote transmission clutch block 8 deflection to reset, owing to trundle 18 passes to the moment that transmission clutch block is certain under driven by motor, therefore the second shank end of elastic on-of pin departs from from angle limit groove 27.Along with the deflection of transmission clutch block 8 resets, the opening of transmission draw-in groove 10 returns to the surface of transmission clutch block 8, and angle alignment pin 28 enters weakened region.Owing to there is ' locked ' zone on the right side of weakened region, stop is lost on the right side of angle alignment pin 28, at this moment, manual unlocking frame 4 is moved to the left a segment distance relative to transmission clutch block 8 and latch frame 1 under the compressing of the first spring, angle alignment pin 28 enters ' locked ' zone, and elastic on-of pin assembly protrudes the second surface of manual unlocking frame 4 under the effect of lozenges and stretches into the lock slots 11 on the right side of transmission clutch block 8 simultaneously.So far, locking is recovered between tooth bar 2 and latch frame 1.Now, transmission clutch block, manual unlocking frame, latch frame and tooth bar are fixed, and are in right limit position together.
