Description
The utility model relates to door, particularly a kind of Electric door against thieves.
Existing security door generally all is installed on the outer body of wall of original timber, forms two sects, and pretty troublesome during people's open and close, inconvenience takes up room again, and this door not only uses inconvenient, but also unreliable, theftproof performance is poor, and the burglar is easy to door is pried open.
The purpose of this utility model is in order to solve the deficiency that the above-mentioned background technology exists, and it is convenient to propose a kind of switch door, and theftproof performance is good, not spacial again Electric door against thieves.
At the foregoing invention purpose, the utility model adopts following technical scheme: a kind of Electric door against thieves, form by doorframe and Door and its lock, chute is arranged in doorframe, door is arranged in the chute of doorframe, its special character is: on the top of doorframe tooth bar 4 is housed, on door, the driven wheel 5 that is meshed with tooth bar 4 is housed with tooth bar 4 corresponding sections, this driven wheel is driven by deceleration device by the motor that is positioned on the door, motor be positioned at Men Nei and control the travel switch K1 of motor positive and inverse and position door lock and the contact switch K3 that is controlled by dead bolt and the normally open push button switch K3K4 of two parallel connections connect, described two button switch K 3K4 lay respectively on Men Nei and the body of wall outdoors.
Doorframe 1 of the present utility model is the double-deck doorframe that adopts special deformed channel steel, angle steel combination, door 2 is made of steel plate, square steel and PLASTIC LAMINATED, doorframe 1 is installed in the body of wall, therefore the open and close of door is by motor-driven,, it is simple to operation, open the door and do not occupy the space, the theftproof performance spy is good, and is aesthetic in appearance, also can use during power failure, can replace two traditional road doors fully.
Below in conjunction with the accompanying drawing illustrated embodiment, describe the utility model in detail.
Fig. 1 is the overall structure schematic diagram of this security door.
Fig. 2 is motor driver and travel switch schematic diagram.
Fig. 3 is A among Fig. 2-A sectional view.
Fig. 4 is a circuit diagram.
Fig. 5 is the structural representation of door lock.

The utility model mainly is made up of doorframe 1, door 2 and door lock 3, wherein, doorframe 1 is the double-deck doorframe that adopts deformed channel steel, angle steel to form, there is a root post its centre with the doorframe dimidiation, wherein half is embedded in the middle of the body of wall, chute is arranged in doorframe, and door 2 places this chute, and can move by left and right sides shuttle in chute.See Fig. 1.
The tooth bar 4 that is arranged in doorframe 1 is meshed with the driven wheel 5 of door 2.See Fig. 2.
Described travel switch K1 is made up of lance 9, a contact 10 and two contacts 12, and lance 9 is positioned at the chute of shop front boss 11, and can horizontally slip in chute.Its two can contact with the end face on the adjacent both sides of doorframe respectively, and lance 9 is hinged with contact 10, and contact 10 is between two contacts 12.See Fig. 2 and Fig. 3.
Described two button switch K 3K4 that often open lay respectively at Men Nei and showy outdoors place.Not expression in the drawings.
Described contact switch K2 is positioned at door lock 3.Door lock 3 is made up of clamp 13, dead bolt 14, cross bar 15, control lever 16, thumb wheel 17, alignment pin 18 and lock core 19, wherein, clamp 13 is positioned on doorframe 1 column on one side, dead bolt 14 be arranged in the door 2 on clamp 13 corresponding lockholes, dead bolt 14 connects firmly mutually with a cross bar 15, spring 21 and spring 22 that dead bolt is upwards driven are housed on dead bolt 14 and cross bar 15, spring 21 is to push away spring, spring 22 is extension springs, one of control lever 16 links to each other with cross bar 15, contact switch K2 is positioned on the control lever 16, controls its break-make by control lever.The side of control lever 16 has the position of tooth to be meshed with profile of tooth thumb wheel 17, and alignment pin 18 can be under the driving of spring 23 in the pin-and-hole in the laterally inserted control lever 16, and the motion of this alignment pin 18 is by lock core 19 controls.When unblanking,, drive the pin-and-hole that alignment pin 18 breaks away from control lever 16 with key rotation lock core 19, at this moment, control lever 16, dead bolt 14, cross bar 15 move upward under the effect of spring 21 and spring 22, make dead bolt 14 leave clamp 13, the state that unlocks, door just can be opened.The controlled bar 16 of contact switch K2 is pushed down simultaneously, is in closure state.When shutting, trackwheel 7, make control lever 16, dead bolt 14 and cross bar 15 move downward, when dead bolt 14 snaps in the clamp 13, in the pin-and-hole of alignment pin 18 automatic insertion control lever 16 sides under the driving of spring 23, promptly be in the lock state, simultaneously, control lever leaves contact switch K2, contact switch K2 automatic disconnection.
