Description
Technical field
The utility model relates to a kind of structure, relates in particular to a kind of structure of security door.
Background technology
Existing security door improves on the door leaf at theftproof lock, theftproof lock place and doorframe mostly, but the rare improvement of door-hinge one side that is connected with hinge at doorframe and door leaf.The slit at door-hinge place became the weak link of security door when security door cut out, and was pried open by the people easily, thereby had influenced the anti-theft effect of security door.
Summary of the invention
At the above-mentioned defective of prior art, the utility model provides a kind of security door, adopts the technical solution of the utility model, can effectively prevent from from the slit of door-hinge one side door to be pried open.
Security door of the present utility model comprises doorframe, door leaf and hinge, is provided with the door-hinge anti-picking device in doorframe, the door leaf junction of described hinge one side, comprises pick-proof limit projection and the safety groove that cooperates with it.
The cross section of pick-proof limit projection and the safety groove that cooperates with it can be square, also can be trapezoidal or other shape.
When security door cuts out,,, also can't open security door even hinge is destroyed because the safety groove of pick-proof limit projection and cooperation with it cooperatively interacts.
Described pick-proof limit projection can be arranged on the doorframe, and safety groove then is located on the door leaf.
For the ease of making, it is synthetic that described pick-proof limit projection and doorframe, safety groove and door leaf are respectively one.
Also described pick-proof limit projection can be located on the door leaf, and safety groove is located on the doorframe.
For the ease of making, it is synthetic that described pick-proof limit projection and door leaf, safety groove and doorframe are respectively one.
The utility model compared with prior art owing to be provided with the door-hinge anti-picking device, security door pick-proof performance improves greatly, even door-hinge is destroyed, security door also can't be opened, and security door simple in structure, be easy to make.
Description of drawings
Fig. 1 is the front view of security door of the present utility model;
Fig. 2 is the perspective view of A-A section among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing a preferred embodiment of the present utility model is elaborated.
As shown in Figure 1, 2, the security door of this preferred embodiment also is provided with the door-hinge anti-picking device in doorframe, the door leaf junction of door-hinge one side except that comprising doorframe 1, door leaf 2 and hinge 3.This door-hinge anti-picking device comprises pick-proof limit projection 4 and the safety groove 5 that cooperates with it.They are connected with the axle sleeve of door-hinge respectively.
Pick-proof limit projection 4 is located on doorframe 1 side in this specific embodiment, and safety groove 5 is located on door leaf 2 sides.Pick-proof limit projection 4 and doorframe 1, safety groove 5 and door leaf 2 are respectively processed by block plate distortion.The cross section of pick-proof limit projection 4 and the safety groove 5 that cooperates with it is trapezoidal.After security door cut out, pick-proof limit projection 4 and safety groove 5 cooperated, even hinge 3 is destroyed, also security door can't be opened.
Described pick-proof limit projection 4, safety groove 5 also can independently be made pick-proof sheet and safety groove, they are installed on door leaf 2 or the doorframe 1 respectively then.
The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present invention; Be all equivalents of being done according to claim scope of the present utility model, be the utility model claim scope and cover.
