Description

Anti-theft door with lock lamp and alarm

The utility model relates to a kind of building unit, particularly a kind of security door.

At present, security door has wooden door outsourcing iron sheet from the structure of door, form by the steel plate square tube, form by steel plate and angle steel or channel-section steel, steel plate is also arranged through bent into shape repeatedly, doorframe have single seam, double stopper arranged, but these doors are made because of metal material, loud when knocking at the door, influence the work and the rest of other resident family, when in the man of resident family nobody the time can worry again to be prized, particularly when the night fell, light is special dark between the building residence, and safe-guard door lock is many, can open the door to the user like this and bring inconvenience.Chinese patent CN2094612U provides a kind of FBM type multi-function door, it is made up of doorframe, door leaf, door lock, peephole, doorbell and alarm, but this door is wanted the whole door body swing, trigger switch, spring vibration just can be reported to the police, and door is gone up no light, the inconvenience of opening the door, this door all can trigger warning when the open and close door, and warning circuit is also complicated.

At above-mentioned situation, the purpose of this utility model is to provide a kind of door body structure reasonable, opens the door conveniently the safety anti-theft door that reliable alarm integrates sound, light, reports to the police.

The utility model is realized as follows: it is by peephole, doorbell, door lock being housed on the door leaf of installing on doorframe, the doorframe, the door leaf, lock-protector being housed on door lock, door lock light is housed on the lock-protector, alarm is housed on the door leaf, at the upper and lower angle of door the alarm control circuit of being made up of two microswitches is housed and forms.The control circuit of alarm is continuous the forming of microswitch that has normally-open normally-close transfer contact respectively by two, constant close contact in constant open contact in the transfer contact of one of them microswitch and another microswitch transfer contact joins, and the constant open contact in the constant close contact in the transfer contact and another microswitch transfer contact joins, and is serially connected in the IC of alarm then ₁And form between the power supply.

Operating principle is as follows: during the lock-protector of dress, just connected the door lock light switch outside opening door lock, the lock lamp is bright and illuminate lockhole, opens security door so that insert key, after door is opened, closes lock-protector, cuts off LED power source, and door lock light goes out; The control circuit of the one-tenth of the alarm that two microswitches being installed by the upper and lower angle of door are formed " with or " interlock switch form, when door when normally opening or closing door leaf, " with or " in " with or " interlock switch connected, alarm is not worked, have only when unnormal unlocking, promptly above door leaf prized or following door leaf when being prized to 1～2 millimeter, OR-gate in " with or " interlock switch is connected, with the power connection of alarm, start alarm, send police whistle sound.

The advantage of the utility model institute tool is: 1, except that the door leaf inner panel, all adopt metal material to make, its doorframe adopts quality steel plate through bent into shape repeatedly, door leaf is stretched by quality steel plate and forms, and inner employing of door leaf organized reinforcing ribs more, has higher strength and stiffness, handsome in appearance, good manufacturability.2, door lock adopts comprehensive anti-drilling door lock, and is safe and reliable.3, the door leaf periphery has flange, can shelves wind, can press the slit between retaining door leaf and doorframe after closing fully, and door leaf edge overlaps fully with the doorframe recess, instrument can't insert, again because of the door leaf inner edge through repeatedly bending " recessed " type, door-plate penetrates " recessed " type groove by the door leaf lower edge not to be had rivet again and fixes, elegant in appearance, increases the integrated beauty of door, and safe and reliable, theftproof performance is good.4, the utility model integrates sound, light, reports to the police, door lock light on the door lock opens the door conveniently, someone can ring a doorbell, when door is prized 1～2 millimeter, microswitch on the door angle starts alarm and sends police whistle sound, and this sound can reach more than 20 meter far away, and it is reliable to report to the police, the component of sound, light, alarm is few, and is cheap.

Further specify the utility model below in conjunction with drawings and Examples.
