Abstract

The utility model discloses an electric theft-proof door with an electronic alarm and a mechanical cipher. Four lock pins on a door frame are inserted into a lock inside a door and are locked, and a key on a mechanical cipher device is used for controlling an electric motor to drive a gear and a connecting rod to unlock the lock. The key is connected with the circuit of an alarm, a mechanical handle is connected with a driving rod, and a safety power source is connected with the electric motor, the alarm, an interphone, and an indicating light via contacts. The utility model has the functions of cipher control, electronic alarming, and theft protection. The key structure of the cipher is simple, the product has anti-shifting and anti-prizing functions, and the cost is low.

Description

Electronic warning machinery password Electric door against thieves

The utility model belongs to a kind of mechanical cipher Electric door against thieves.

Known security door is generally used metal material, and the door inner structure adopts kinematic link, mechanical lock to realize locking in 4 o'clock to 8 o'clock, and mechanical lock is more than two, the drive mechanism complexity, and price is higher.

The purpose of this utility model is to provide a kind of electronic warning machinery password Electric door against thieves, to improve security door insurance function, simplified structure, reduction price.

The electronic warning machinery password Electric door against thieves that the utility model provides, characteristics are that four lock pins insert the locking of door inner lock buckle on the doorframe, and by opening lock pin by key control drive of motor gear, tooth bar, connecting rod, latch on the mechanical cipher device, key circuit and alarm link, latch and contact, position link, the machinery handle links with drive link, and safety power supply connects motor, alarm, intercom, indicator lamp, mechanical cipher device by the contact.Wherein, described mechanical cipher device contains digital button contact, check mark plate, permanent magnetism contact, guide rod contact, counter-rotating contact; Described motor is work drive motor and standby motor, is fixed on the fulcrum both sides, by spring and change-over switch location; Described connecting rod upper right side is established automatic outage push rod, and the lower-left end is equipped with the verbal cue device.

The utility model opens the door does not need key, and according to the password key electric open-door, password key pushes the wrong alarm equipment alarm, has increased the function of security door, also has intercom to converse simultaneously, and password key is simple in structure, obviously reduces cost and reduces price.

Fig. 1 the utility model front view.

Fig. 2 Figure 1A-A sectional view.

Fig. 3 door removes bonnet internal construction schematic perspective view.

Further describe structure of the present utility model below in conjunction with accompanying drawing.

Consult Fig. 1, Fig. 2, lock pin 11 on the doorframe 1 inserts the snap close latch positioning and locking of door 2, there are weather strip and doorframe sternly to close sealing in the door, intercom 4 can be realized an inside and outside intercommunication, numeral in the mechanical cipher device 3 shows mouthful one group of password of 9 demonstration digitized representations, move positioning button 8 and can adjust the demonstration numeral, mix up the demonstration numeral, press pairing password key 5 to make permanent magnetism contact 20 closures, motor 28 is just changeing, travelling gear 31, tooth bar 32 is stirred drive link 33 and is moved to left and open the lock pin (see figure 3), and doorframe upper spring 37 flicks door, and guide rod 18 moves to left under spring 19 effects, guide rod contact 21 breaks away from, and contact 24 makes an outage.At closing time, doorframe extruding guide rod 18 moves to right, and contact 21, pressure point 22 make contact 23 closures, and motor counter-rotating driving rack is stirred the drive link locking of closing the door that moves to right, after putting in place, verbal cue device 35 disconnects, as not shutting, send signal, push rod 25 jack-up contacts 21 make contact 24 disconnect system cut-off simultaneously.Machinery handle 15 can move drawing on 14, and the other end is associated on the drive link 33, is pulled outwardly the machinery handle, but moves the hand switch door lock on handle.Two same motor, one is standby, if any accident, is 180 ° of dead springs 29 with special key twisting conversion button 10 outdoors, contact 36 closures, standby machine operation is opened the door.

If press the button number wrong, the push rod contact on the button can not make the permanent magnetism closing of contact by the hole, but directly presses mobile electroplax 17, and power supply 36 and alarm 38 UNICOMs send audible alarm.Wherein power supply 36 is identical with the power of battery compartment 7, and it is bright to open crypto control unit 3 rear indicator lights 6.

Claims
