Figure two is the enlarged drawing of door contact and switch.

Figure three is the rear elevation of door and doorframe.

Figure four is the longitudinal sectional view of door and doorframe.

Figure five is the enlarged drawing of lock body.

Figure six is the structural representation of lock body.

Figure seven is steel body doorframe figure.

Figure eight is a steel body doorframe longitudinal section.

Figure nine is the alarm wiring diagram.

With reference to figure one, figure two, on the contact surface top of door 1 and doorframe 2 feeler lever 5 is housed, the next door is provided with the constant close contact K switch ₃, feeler lever 5 dresses at one end have in the box 7 of lid, by spring 6 controls, close 1 o'clock to the doorstep, and feeler lever 5 is retracted in the box 7, answers back to K switch simultaneously ₃Make its disconnection, opened door at 1 o'clock, feeler lever 5 stretches out outside the box 7 K under spring 6 effects ₃Auto-closing, box 7 and K switch ₃Be fixed on the door 1 with clip 8,9.

See figure three to figure six, on the axis hole of the slow-witted dead bolt gear 16 of lock body 18 cam 15 is housed, cam 15 is the oblate cylinder cambered surface of pruning, its other constant open contact K switch that is provided with ₁, when inserting tapered end 3 rotational lock core gears 17, then to stir slow-witted dead bolt gear 16 and make slow-witted dead bolt 14 stretch out lock body 18 outer (promptly locking the door 1) with key, cam 15 just withstands K switch simultaneously ₁Make the constant open contact closure, with K ₁And K ₃Be connected in the loop of alarm 10 in charged source, screw in and but opened door 1, K so in the lock bodies 18 as long as key useless will be stayed dead bolt 14 like this ₁, K ₃Will and report to the police with alarm 10 formation loops.Concrete alarm circuit is seen figure nine.

If the square bar hole 12 of mounting knob 4 is arranged on lock body 18, can on square bar hole 12, load onto cam 11, cam 11 is the oblate cylinder cambered surface of pruning, its other constant open contact K switch that is provided with ₂, K switch ₂With K switch ₃The two ends parallel connection, when locking the door, K ₃Disconnect K ₁Closure if there is people's rotating handles 4 to attempt to rotate livelock tongue 13, then makes cam 11 answer back to K ₂Make its connection, thereby connect alarm 10 loops and report to the police.

Locked door 1 when preventing that owner is in and people's swing handle 4 is arranged and report to the police, hand switch K has been housed on door 1 ₄, K ₄Be connected in the loop of alarm 10.

In order to strengthen the fastness of door 1 and door 2, the frame form of door 1 usefulness figure three can be made, doorframe 2 usefulness steel plates are made by the form of figure seven, figure eight.
