Description

Anti-pry safety door

The utility model relates to a kind of door, particularly a kind of Anti-pry safety door.

Existing entering house door and security door generally are two fan doors, and the inlet chamber domestic demand is made troubles to the user with two locks on two key operated two fan doors, also have on the market entering house door and security door are integrated, but structure complexity, manufacturing cost is higher.

The purpose of this utility model is: a kind of technical scheme of Anti-pry safety door is provided, and this anti-prying goalkeeper's entering house door and security door are integrated, as long as with opening different locks with different keys, structure is simpler, low cost of manufacture, and switch is convenient, and is safe and reliable.

The technical solution of the utility model is: Anti-pry safety door, comprise door leaf and doorframe, door leaf one side and doorframe flexibly connect with hinge, on another side of door leaf safety lock is housed, with on the doorframe of safety lock corresponding position snap close is housed, in one side of doorframe dress snap close the latch interlinked mechanism is housed, latch corresponding pin hole on doorframe that the dead bolt push pedal that the latch interlinked mechanism promotes to connect with trace by dead bolt drives on the trace inserts in the pin hole corresponding on the door leaf, to strengthen the performance of anti-prying.

The latch interlinked mechanism has two traces up and down, the lower end of last trace upper end and following trace is connected with latch respectively, porose respectively being sleeved on the pitman pin in last trace lower end and following trace upper end, and can on pitman pin, be free to slide, also be set with spring on the pitman pin, the effect of spring is to open when lock, when dead bolt does not act on the dead bolt push pedal that is connected with trace, spring tension resets trace, simultaneously the latch on the trace withdraws from the corresponding pin hole from the door leaf, door is promptly opened, pitman pin is fixed in the latch interlinked mechanism shell, the centre position of two traces flexibly connects with a part respectively up and down, can rotate around tie point, and a part is connected with latch interlinked mechanism shell, latch interlinked mechanism shell is connected with doorframe, be connected with the dead bolt push pedal on the trace, the dead bolt push pedal places in the dead bolt push pedal chute on the doorframe, stretches in the snap close simultaneously.

Be fixed with pin at door leaf respectively above or below hinge that doorframe is connected, on the doorframe of upper and lower, and on the door leaf of pin corresponding position the pinhole that is complementary with pin arranged, door leaf is shut, pin inserts in the pinhole, increase the anti-prying performance, door leaf is opened, and pin withdraws from from pinhole.

Last trace upper end and following trace lower end are fixedly connected with 1 or 2,3 latches respectively, simultaneously on the doorframe with door leaf on opposite position the pin hole that is complementary is also arranged.Pitman pin also can directly be fixed in the doorframe, and a part also can directly be fixed in the doorframe.The radial section of doorframe be "

" shape.

Major advantage of the present utility model is: general entering house door and security door are combined into Yishanmen, as long as with opening different locks with different keys, just in the energy inlet chamber, promote interlinked mechanism by dead bolt and drive latch, door is opened, structure is simpler, manufacturing cost is lower, and switch is convenient, and is safe and reliable.

Embodiment 1:

Accompanying drawing 1 provides an embodiment of Anti-pry safety door, Anti-pry safety door comprises door leaf 1 and doorframe 2, door leaf one side and doorframe flexibly connect with hinge 3, on another side of door leaf safety lock 4 is housed, with on the doorframe 2 of safety lock corresponding position snap close 5 is housed, in one side of doorframe dress snap close latch interlinked mechanism 6 is housed, latch 9 corresponding pin hole on doorframe 2 that the dead bolt push pedal 8 that latch interlinked mechanism 6 promotes to connect with trace 10 by dead bolt 7 (see figure 2)s drives on the trace inserts in the pin hole corresponding on the door leaf 1.

Latch interlinked mechanism 6 (is seen Fig. 3, Fig. 4) two traces are up and down arranged, the lower end of last trace 10 upper ends and following trace 11 is connected with latch 9 respectively, porose respectively being sleeved on the pitman pin 13 in upper end of the lower end of last trace 10 and following trace 11, and can on pitman pin, be free to slide, also be set with spring 14 on the pitman pin, pitman pin is fixed in the latch interlinked mechanism shell 15, the centre position of two traces is porose respectively up and down is enclosed within on the part 16, can rotate around a part, propping up part 16 is connected with latch interlinked mechanism shell 15, latch interlinked mechanism shell 15 is connected with doorframe 2, dead bolt push pedal 8 is connected with trace, dead bolt push pedal 8 places in the dead bolt push pedal chute on the doorframe 2, can freely-movable in chute, stretch into simultaneously in the snap close 5.

Embodiment 2:

With the difference of embodiment 1 be: above or below hinge 3 that doorframe 2 is connected, on the doorframe of upper and lower, be fixed with pin 12 (see figure 1)s respectively at door leaf 1, with on the door leaf of pin 12 corresponding positions the pinhole that is complementary with pin is arranged, at closing time, pin can insert pinhole, strengthens the anti-prying performance.
