Aforesaid a kind of many lock pins of security door device, wherein said α angle are 90 °＜α＜180 °.
Aforesaid a kind of many lock pins of security door device, wherein said secondary dead bolt down also is a sheet material, its upper end is connected with rear jaw by bearing pin, its upper end also has a U type groove, the guide finger that is fixed on the lock body just slides in this U type groove, has a chute in its underpart, and sliding in this chute is provided with the guide finger that is fixed on the lock body, be connected with a lower link in its lower ends downward by bearing pin, the bottom of lower link is to having down lock pin.
Advantage of the present utility model is to adopt the interpolation type lockset, and by the improvement to lockset, secondary dead bolt realizes that with following secondary dead bolt horizontal and vertical lock pin enters doorframe in the increase, to reach the purpose that strengthens pick-proof.Have compact conformation, hidden, strengthen the characteristics of pick-proof performance, prevent the mistake lock, multi-faceted pick-proof and anti-theft.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model user mode schematic diagram.
As shown in Figure 1, the utility model includes interpolation type lockset and lock body 16 thereof, lock core 17, sincere hand 18, main dead bolt 7, between the preceding intermediate plate of lock body 16 and rear jaw, be provided with on one secondary dead bolt 5 and secondary dead bolt 10 down, the upper end of last secondary lock 5 is connected with a upper connecting rod 2, its upper end is for inserting the last lock pin 1 in the upper door frame, and the lower end of following secondary lock 10 is connected with a lower link 14 can insert the interior lock pin 15 down of lower door frame.Going up secondary dead bolt 5 is the sheet material that upper and lower two parts axis becomes angle α, and its angle α is 90 °＜α＜180 °.Upper end at an upper portion thereof upwards is connected with a upper connecting rod 2 by connecting pin 3, the upper end of upper connecting rod 2 upwards is provided with lock pin 1, top at last secondary dead bolt 5 has a limit sliding chutes 19 along axis direction, slide in this limit sliding chutes 19 and be provided with the guide finger 4 that is fixed on the lock body 16, bottom at last secondary dead bolt 5 also has a chute 20 along axis direction, and the bearing pin 6 that is fixed on the main dead bolt 7 preceding intermediate plates is formed a kinematic pair with this chute 20.Secondary dead bolt 10 also is a sheet material down, its upper end is connected with rear jaw by bearing pin 9, its upper end also has a U type groove, the guide finger 8 that is fixed on the lock body 16 just slides in this U type groove, have a chute 21 in its underpart, be fixed on the just motion in this chute 21 of guide finger 12 on the lock body 16, be connected with a lower link 14 in its lower ends downward by bearing pin 13, the bottom of lower link is to being provided with down lock pin 15.
During the utility model work, as shown in Figure 1, 2, when locking a door, rotate sincere hand 18 earlier, upper and lower secondary dead bolt 5,10 stretches out, driving upper and lower lock pin 1,15 through upper and lower pull bar 2,14 moves, enter in the doorframe jack, use one week of key turns then, stretch out main dead bolt, at this moment, upper and lower secondary dead bolt 5,10 and windproof oblique tongue 11 all are lockable.It is that key is inserted lock core 17 that its concrete mistake becomes, rotate a week by the shown position clockwise direction, main dead bolt 7 is moved to the left, enter the doorframe left vertical beam, and the bearing pin 6 that is fixed on the main dead bolt 7 preceding intermediate plates is formed a kinematic pair with the chute 20 (oblique lower-left) of last secondary dead bolt 5, upward secondary dead bolt 5 is fixed on the constraint of the guide finger 4 on the lock body 16, moving to left of bearing pin 6, change into and go up moving up of secondary dead bolt 5, by the upper connecting rod 2 that is connected with last secondary dead bolt 5 by connecting pin 3, make lock pin 1 enter the doorframe top rail, and the bearing pin 9 that is fixed on main dead bolt 7 rear jaws is formed a kinematic pair with the chute 21 (oblique top) of following secondary dead bolt 10, down secondary dead bolt 10 is fixed on the axis of guide 8 on the lock body 16 and 12 constraint, moving to left of bearing pin 9 moves down secondary dead bolt 10, by the lower link 14 that is connected with following secondary dead bolt 10 by connecting pin 13, make down lock pin 15 enter the doorframe lower transverse beam, finish door lock and close program.At this moment, be in the windproof dead bolt 11 of the state of stretching out, hindered, can not make retraction movement (sincere hand 18 clockwise directions can not rotate) because of following secondary dead bolt 10 is in the lower position.At this moment, windproof oblique tongue 11 has also played the effect of pick-proof fulcrum.
When opening the door, key inserts lock core 17, counterclockwise rotates a week by shown position, promptly oppositely circle with key earlier, main dead bolt 7 is return, then the sincere hand 18 of backward rotation, upper and lower secondary dead bolt 5,10 drives upper and lower pull bar 2,14, and upper and lower lock pin 1,15 resets.Be rotated further sincere hand 18, windproof oblique tongue 11 withdrawals, door is opened.The locking states of door is removed in the opposite motion when all doing with original locking of main dead bolt 7, secondary dead bolt 5 and 10.Clockwise direction rotates sincere hand 18, windproof oblique tongue 11 withdrawals, and door can be opened.
Close behind the door in the inlet chamber, move sincere hand anti-rotation inserted sheet 22, can under the state of not locking a door, because of sincere hand 18 can not rotate, reach the purpose that to open the door, in order to avoid the stranger arbitrarily swarms into to main dead bolt 7 moving directions.
After locking a door night, stretch out direction to main dead bolt 7 and move sincere hand anti-rotation inserted sheet 22, the outdoor use key can only be opened main dead bolt 7, and upper and lower secondary dead bolt 5,10 remains locking state, thereby increases the sense of security.
Fig. 1,2 is depicted as three lock pin mechanisms, if increase by a changement between upper and lower pull bar and upper and lower lock pin, can realize more lock pin.
