Abstract
The utility model relates to a theft-proof door which comprises a door frame (1), a door leaf (2), and a pair of a first prizing-proof board (4) and a second prizing-proof board (5) which are respectively arranged at the opening sides of the door leaf and the door frame. When the door leaf is closed, the first prizing-proof board (4) is positioned between the second prizing-proof board (5) and the side wall of the door frame (1). The first prizing-proof board (4) and the second prizing-proof board (5) are respectively provided with lock tongue holes (6, 7) through which a lock tongue (3) can travel. The door frame (1) and the door leaf (2) are arranged with steps at the closing sides. The prizing-proof boards (4, 5) are respectively arranged on the outer side surfaces of the steps of the door leaf and the door frame in mutual parallel. The utility model adopts an interlocking device between the door leaf and the door frame. When the door is prized, the door leaf and the door frame are tighter as being prized more, the lock tongue can not escape from the door frame, and the theft-proof performance is good. The theft-proof door structure is simple, and has low cost.
Description
Technical field
The utility model relates to a kind of security door.
Background technology
Security door is of a great variety now, and traditional security door all adopts local lock power effect, by the support of door body doorframe is carried out lock control with the function that the tongue formula is advanced to stretch.Yet,, can make dead bolt deviate from doorframe and lose antitheft effect in case door lock lock district is destroyed.And the anti-theft device more complicated of existing security door employing, the cost height.
Summary of the invention
At the shortcoming of existing security door, the technical problems to be solved in the utility model provides a kind of simple in structure, security door that security performance is high.
In order to solve the problems of the technologies described above, the technical scheme that the utility model is taked is: a kind of security door, comprise doorframe, door leaf and anti-picking device, described anti-picking device is a pair of first anti-skid plate that is parallel to each other and the second anti-skid plate that is separately positioned on door leaf and doorframe open side; Described door leaf is under closure state, and the first anti-skid plate is between the doorframe sidewall and the second anti-skid plate.
Establishing dead bolt hole respectively on the described first anti-skid plate and the second anti-skid plate passes for dead bolt.
The beneficial effect that the utility model has compared to existing technology is: the utility model adopts the interlock between door leaf and the doorframe, and when forcing open the door, door leaf and doorframe only can be prized tighter and tighter, and dead bolt can not deviate from doorframe, and theftproof performance is better; And this kind security door is simple in structure, and cost is low.
Description of drawings

Fig. 2 is the schematic cross-sectional view of the utility model when opening the door.
Fig. 3 is the generalized section of the of the present utility model first anti-skid plate.
The specific embodiment
Now be described with reference to the accompanying drawings the specific embodiment of the present utility model.
Fig. 1 is the schematic cross-sectional view of the utility model when closing.The utility model comprises doorframe 1, door leaf 2 and anti-picking device.Door leaf 2 can be along A to Unscrew.Anti-picking device comprises a pair of anti-skid plate 4,5 that is separately positioned on door leaf and doorframe open side, and the two is preferably and is parallel to each other, and can establish dead bolt hole 6,7 on it respectively and dead bolt 3 be passed stretch in the doorframe door lock is dead.The first anti-skid plate 4 is located on the door leaf 2, and the two can connect by securing members such as screws; The second anti-skid plate 5 is located on the doorframe 1, and the two also can connect by securing members such as screws.When door was closed, the first anti-skid plate 4 was between doorframe 1 sidewall and the second anti-skid plate 5.When forcing open the door, when door leaf 2 past directions away from doorframe 1 were prized, the first anti-skid plate 4 was blocked by the second anti-skid plate 5, and more firmly prizes, and prevents that the resistance of 5 pairs of anti-skid plates 4 of skid plate is big more, and door leaf is not easy to break away from doorframe more.
Also can be between above-mentioned anti-skid plate and door leaf and the doorframe by welding or other fixed form;
Fig. 2 is the schematic cross-sectional view of the utility model when opening the door.Because the first anti-skid plate 4 and the second anti-skid plate 5 are parallel to each other opening on the direction of door, can not interfere mutually, thereby door leaf are free to rotate.
