The direction bending of door machine beam 1 is tilted or tilted to the direction bending away from door machine beam 1, this can be train door according to stopping sliding door by
Filled in outside car at car door mouth or in-car is filled at car door mouth and determined.Directive wheel 8 has been respectively articulated with two train door connecting plates 2,
Directive wheel 8 is stretched into the train door guide rail 7 relative with 2 positions of train door connecting plate where it, and directive wheel 8 is in train door guide rail 7
Interior slip, train door enter line slip completely along the restriction range of train door guide rail 7, realize that the plug of train door is pull-type and play on or off
Close.
As shown in figure 1, two train door connecting plates 2 are located at the side of door machine beam 1, the opposite side centre position of door machine beam 1
Provided with locking mechanism.As shown in FIG. 3 to 7, locking mechanism includes：Two latch hooks 9, the locking swing rod among two latch hooks 9
10th, respectively two lock pins 11 positioned at two both sides of latch hook 9, pull the sliding electromagnet 12 of the rotation of locking swing rod 10, be enclosed on and push away
Draw the back-moving spring 13 on electromagnet 12.Two latch hooks 9 and locking swing rod 10 are installed on a bearing 14, and the bearing 14 is fixed
On door machine beam 1, the middle part of latch hook 9 is hinged on the side of bearing 14, and the bottom centre of locking swing rod 10 is also articulated to bearing
On 14 side, the bottom both ends of locking swing rod 10 are provided with two dead bolts 15, and two dead bolts 15 are convex towards two latch hooks 9 respectively
Go out.End face on latch hook 9 close to locking swing rod 10 is arc surface 16, is provided with latch hook 9 close to the other end of lock pin 11
Lockhole 17, the bottom both ends of latch hook swing rod 10 are provided with two cancave cambered surfaces 18 coordinated with the radian of arc surface 16, the arc surface of latch hook
16 are bonded when lock pin 11 is not slipped into lockhole 17 and are connected on cancave cambered surface 18, and now the opening of lockhole 17 is inclined towards lock pin 11
Tiltedly, in order to which the motion of lock pin 11 slips into, arc surface 16 is close to cancave cambered surface 18 and rotated when latch hook 9 rotates, and ensures during rotating
Locking swing rod 10 will not be swung.One-level re-entrant angle 19 is additionally provided with the arc surface 16 of latch hook 9, the one-level re-entrant angle 19 can be with latch hook
9 rotation and the clamping of dead bolt 15.One end of sliding electromagnet 12 be provided with can electrically controlled telescoping push-pull shaft 20, push-pull shaft 20 is logical
The top for crossing a connecting rod and locking swing rod 10 is articulated and connected, and the stretching motion of push-pull shaft 20 can control the rotation shape of latch hook swing rod 10
State, the rotation status of two latch hooks 9 is locked, to realize that two latch hooks 9 are locked or unlocking motion to two lock pins 11.
Preferably, as shown in Fig. 5,7, the side of latch hook 9 is additionally provided with the spacing recess of connection one-level re-entrant angle 19, on bearing 14
Provided with two shift fingers 21 being located at respectively in the spacing recess of two latch hooks 9, when lock pin 11 slides in or out lockhole 17, lock
Hook 9 is located exactly at the both ends in spacing recess by promotion rotation to extreme position, now shift finger 21.Shift finger 21 can play limit
The effect of the slewing area of lockmaking hook 9, make the locking of train door or unblock more stable reliable.In order that latch hook 9 is kept after rotation
Correct position, latch hook 9 are provided with moving magnet 22, and the side of bearing 14 is provided with two and repelled each other with the peer of moving magnet 22
Fixed magnet 23, for two fixed magnets 23 respectively on the rotational trajectory of two moving magnets 22, moving magnet 22 can be with
Latch hook 9 rotation to the corresponding aligned in position of fixed magnet 23.A depth is additionally provided with the arc surface 16 of latch hook 9 and is less than one-level
The two level re-entrant angle 24 of re-entrant angle 19, latch hook 9 is promoted to rotate when lock pin 11 is slipped into lockhole 17, dead bolt 15 is sliding after two level re-entrant angle 24
Enter in one-level re-entrant angle 19, the purpose of design of two re-entrant angles is there are two states when locking locking swing rod 10, can be achieved secondary
It locking, when special circumstances occur and causing locking to fail, can still ensure that train door can not be opened by secondary locking, ensure passenger
Safety.When dead bolt 15 slips into one-level re-entrant angle 19 or two level re-entrant angle 24, two Impact directions of dead bolt 15 of locking swing rod 10 all exist
On same straight line, and the straight line passes through the pivot of locking swing rod 10, does not produce moment of torsion during locking, largely avoids shaking
The dynamic danger for causing to break off relations.
More excellent, as shown in Fig. 3,6, lock pin 11 is arranged on a belt clamp 25, and being fixed on sliding block by belt clamp 25 pacifies
Fill on seat 3, sliding block mounting seat 3 is connected on timing belt 4 by belt clamp 25, and two sliding block mounting seats 3 are connected to synchronization
With 4 not on homonymy, move toward one another or opposite motion are carried out in order to synchronous.Belt clamp 25 is provided with the bar shaped laterally set
Hole, the end of lock pin 11 are locked in the bar hole by nut and pad, and lock pin 11 can adjust lateral attitude along bar hole, with
Control the tightness of the plug drawing amount after train door closing and train door closing.
The automatic blocking process of locking mechanism is as follows, as shown in fig. 6, when train door is not turned off, sliding electromagnet 12 is in
Off-position, because bottom both ends of two latch hooks 9 respectively with locking swing rod 10 in unlocking condition abut, shift finger 21 limits
The rotation in the direction of latch hook 9 one, fixed magnet 23 limit the rotation of the other direction of latch hook 9, and now locking swing rod 10 tilts in stable
State, the position of push-pull shaft 20 of sliding electromagnet is identical with position during energization adhesive, and back-moving spring 13 is compressed, timing belt
During the move toward one another of transmission component band movable slider mounting seat 3, train door progressively closes off, two lock pins 11 to central motion extremely
Slip into the lockhole 17 of two latch hooks, two lock pins 11 are further continued for, to central motion, promoting two latch hooks 9 to rotate, when locking is put
When two dead bolts 15 on bar 10 cross one-level re-entrant angle 19, the reset of card under the rebound effect of back-moving spring 13 of locking swing rod 10
Firmly one-level re-entrant angle 19, latch hook 9 are blocked by dead bolt 15 and can not reversely rotated, as shown in figure 3, now the opening of lockhole 17 turns to court
On, lock pin 11 can not transverse shifting abjection lockhole 17, so as to realize the locking of train door.
The automatic unlocking process of locking mechanism is as follows, as shown in figure 3, when train door needs to open, sliding electromagnet
Push-pull shaft 20, which is powered, to be shunk, and pulls locking swing rod 10 to rotate, and back-moving spring 13 is compressed, and now the dead bolt 17 of locking swing rod 10 is de-
From one-level re-entrant angle 19 and two level re-entrant angle 24, the constraint to latch hook 9 is discharged, toothed belt transmission component band movable slider mounting seat 3 is carried out
Opposite motion, promote two latch hooks 9 to rotate to the both ends of the opening difference propylaeum machine beam 1 of two lockholes 17 and tilt, sliding block installation
Seat 3 continues to move, and lock pin 11 departs from lockhole 17, and train door is gradually opened, and latch hook 9 departs from the rotational restraint scope of locking swing rod 10
Afterwards, sliding electromagnet push-pull shaft 20 power-off release, as shown in fig. 6, now due to locking swing rod 10 bottom both ends respectively with
