Description

Prevent forcing open the door from connecting from card

The utility model relates to a kind of oneself card that connects certainly that is used for usefulness such as door and window, safety cabinet, official document cabinet to be prevented forcing open the door.

The door of Xiao Shouing, safety cabinet all are to connect the doorframe strength paper with loose-leaf in the market, can only lock outside, and dead bolt just blocks very short some, has multiple insecure factor, just can pry open with an iron rod, and is obviously dangerous during use.

The purpose of this utility model just provides a kind of pick-proof prevents pounding, and safe in utilization connecting certainly from card prevented forcing open the door.

Solution of the present utility model is such: by doorframe 1, door leaf 9, loose-leaf hinge and lock are formed, 1 liang of vertical edges of doorframe leaves hollow projection 10,9 liang of flaps of door leaf leave recess, projection 10 on recess and the doorframe 1 adapts, one side of doorframe 1 connects into the loose-leaf hinge with rotor 3 with doorframe 1 and door leaf 9, another side is equipped with the pin 4 that moves down respectively up, pin 4 can insert recessed 10 interior internal lock 5 of using of hollow of doorframe 1 respectively and lock, after taking above-mentioned measure, the intensity of loose-leaf hinge strengthens greatly, and owing to be to adopt internal lock locking, the person of forcing open the door can only stretch into a hand and prizes internal lock from little, very difficulty is opened internal lock, thereby the utility model safety is firm.

The utility model has the advantages that pick-proof is anti-pounds, and safety firmly.

Accompanying drawing is the utility model embodiment.

The structural representation that accompanying drawing 1 is the utility model direction is seen in the room.

Accompanying drawing 2 is structural representations of opening behind the internal lock snap close b.

The utility model is made up of doorframe 1, door leaf 9, leaf hinge and lock, 1 liang on doorframe Vertical edges leaves hollow projection 10, and 9 liang of vertical edges of door leaf leave recess, recess and doorframe 1 On projection 10 adapt, one side of doorframe 1 connects into doorframe 1 and door leaf 9 with rotor 3 Leaf hinge, another side are equipped with respectively towards the pin 4 that moves up and down, and pin 4 can be distinguished The hollow projection 10 that inserts doorframe 1 is interior with internal lock 5 lockings.

In the present embodiment, doorframe 1 upper protruding block 10 all adopts steel pipe system with the recess that door leaf 9 stays Become, insert garden steel rotor 3 in the hinged place, thereby two 2 is welded and consists of leaf hinge from the hole. Be hinged with internal lock snap close 6 at door leaf 1, after internal lock snap close 6 rotates internal lock 5 lockings, both sides Withstand in the hollow projection 10 that bottom pin 4 inserts it into doorframe 1, thereby door and frame are joined As a whole, have groove on the projection of door leaf 9, upper bottom pin 4 inserts in the projection pin The shank of the key of son 4 is exposed at the projection place, and b withstands pin handle by the internal lock snap close.

When adopting the utility model to lock a door outside, unblank earlier 8, wicket 7 is opened, stretch Hand enters to strain door, pushes the position locking up and down son 4, rotates internal lock snap close 6 and is anchored on the doorframe On the lock, withstand up and down lock 4, with safety internal lock 5 lockings, again wicket 7 usefulness lock 8 locks Tightly, door lock just pins, and when opening the door, unblanks earlier 8, and handle stretches into opens internal lock 5, rotates Internal lock snap close 6, transfering to up and down, lock 4 just can open the door.

Adopt the utility model can make the door lock of various doors, window, insurance frame etc.

When adopting the utility model, doorframe 1 is to adopt angle steel or section bar to make, and projection is welded on the doorframe 1 with steel pipe, and the both sides up and down of door leaf 9 can be made with steel pipe, and also available angle steel or section bar are made, and the steel plate of burn-oning again just constitutes door leaf.
