Description
Technical field
The utility model is related to a kind of antitheft door, especially a kind of antitheft door based on radio frequency identification.
Background technology
Antitheft is always people's the problem of paying close attention in daily life, in order to avoid burglary, existing most of families at present
Front yard all selects installation antitheft door, and anti-theft effect is improved by increasing the complexity of key and the compactedness of door-plate, still,
With the raising of anti-theft technique, the pilferage technology of burglar is also being correspondingly improved, common anti-theft technique can not play compared with
Good anti-theft effect, especially after thief opens door and enters room, without corresponding warning device, even more allow burglar without
Feared, it is handy.Therefore, in conclusion existing current antitheft door lacks burglar alarm, anti-theft effect is poor.
Utility model content
The purpose of the utility model is to provide a kind of antitheft doors based on radio frequency identification.The utility model has antitheft
The good feature of effect；In addition, also having warning device simple in structure, the characteristics of reasonable design.
The technical solution of the utility model：A kind of antitheft door based on radio frequency identification, includes doorframe, and doorframe is interior through hinge
It is connected with door-plate, the inside for being located at the doorframe of hinge side is equipped with trigger switch, and trigger switch is connected with frequency read/write, radio frequency
Reader is connected with alarm lamp and buzzer, and the key coordinated with antitheft door is internally provided with radio electronic label；The triggering
Switch includes the inverted U-shaped frame inside doorframe, and symmetrical 2 stationary contacts are equipped with close to the side of hinge in inverted U-shaped frame,
In stationary contact connect power supply, the side of another connection frequency read/write, stationary contact is equipped with movable contact, is passed through between movable contact
Metal bridge connects, and compression spring is equipped between the side of metal bridge and the inside of inverted U-shaped frame, and the other side is equipped with kinematic link, and transmission connects
One end of bar is pierced by the medial surface of doorframe.
Antitheft door above-mentioned based on radio frequency identification, one end of the kinematic link are stretched out after being pierced by the medial surface of doorframe
0.5-1cm。
The beneficial effects of the utility model：
1, the utility model in the inside of doorframe by being arranged trigger switch, and frequency read/write is connected to trigger switch
On, radio electronic label is being set on the key, and trigger switch is opened after opening door, and frequency read/write works and identifies electronics
Label, sends out alarm when not recognizing electronic tag, and burglar not only needs accurately to open door lock when opening the door, and also wants
With corresponding electronic tag, difficulty is very large, thus substantially increases antitheft effect.
2, the utility model connects movable contact, and touch dynamic by the way that kinematic link is arranged on the inside of doorframe by metal bridge
Stationary contact is arranged in point side, the characteristics of the separation inside enabling and at closing time door-plate and doorframe is reasonably utilized and contacts, if
Trigger switch is counted, reasonable design is simple in structure；And it can accurately react, connect with the action of enabling
The power supply of frequency read/write, induction is very sensitive, further improves anti-theft effect.

Specific implementation mode
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model
The foundation of limitation.
The embodiments of the present invention：
A kind of antitheft door based on radio frequency identification includes doorframe 1, is connected through hinge 2 in doorframe 1 as illustrated in the accompanying drawings from 1 to 3
There is door-plate 3, the inside for being located at the doorframe 1 of 2 side of hinge is equipped with trigger switch 4, and trigger switch 4 is connected with frequency read/write 5, penetrates
Frequency reader 5 is connected with alarm lamp 7 and buzzer 6, and the key 8 coordinated with antitheft door is internally provided with radio electronic label 9；Institute
It includes the inverted U-shaped frame 41 inside doorframe 1 to state trigger switch 4, is equipped with close to the side of hinge 2 in inverted U-shaped frame 41 symmetrical
2 stationary contacts 42, one of stationary contact 42 connect power supply, another connection frequency read/write 5, the side of stationary contact 42 is set
There is movable contact 43, connects through metal bridge 44 between movable contact 43, be equipped between the side of metal bridge 44 and the inside of inverted U-shaped frame 41
Compression spring 45, the other side are equipped with kinematic link 46, and one end of kinematic link 46 is pierced by the medial surface of doorframe 1.
0.5-1cm is stretched out in one end of the kinematic link 46 after being pierced by the medial surface of doorframe 1.
Operation principle：When door-plate 3 is closed, the surrounding of door-plate 3 is contacted with the medial surface of doorframe 1, and kinematic link 46 is squeezed
Enter the inside of doorframe 1, metal bridge 44 is jacked up upwards, and movable contact 43 and stationary contact 42 is made to detach, and the power supply of frequency read/write 5 is disconnected
