Abstract

The utility model relates to an electric control automatic door lock which is mainly composed of a movable lock shell, a fixed lock shell, a bolt, a handle, a slide plate, a lock head, a spring, an electromagnet assembly, a controller and other parts. Primarily, the slide plate which can move right and left in the movable lock shell is fixed with the bolt and is held still by a lever top plate behind controlled by the electromagnet; the lever top plate can be clamped by a claw of a shifting sheet driven by the lock head or a shifting sheet driven by a turn knob on the movable lock shell. The on-off of a power supply of the electromagnet is controlled by a remote controller or a cipher. The utility model has dual theft protection for open insurance, overcomes the defect that the existing electronic door lock can be opened by a key or the remote controller (or the cipher) under the condition of available electricity, and can be automatically locked with convenient operation.

Description

Automatically controlled automatic door lock

The utility model relates to a kind of electric control door lock.

Existing machinery door lock, electronic lock exist the anti-dissatisfactory shortcoming of pirate of the open performance, often have the pirate of the open lockset larceny case of registering one's residence to take place.

The purpose of this utility model is to provide a kind of door lock that adopts Electromagnetic Control locking dead bolt, has higher anti-pirate of the open safety.

The technical solution of the utility model is: the left end of sliding panel fixedly the dead bolt sliding panel be coupled to moving lock housing with extension spring, tongue is bumped in left end installation at bottom lining plate, left upper end hinge connection lever baffle plate, the lever baffle plate is coupled to bottom lining plate by stage clip, the right-hand member of bottom lining plate is installed electromagnet, upper right side hinge connection lever top board 1, lower right hinge connection lever top board II, between lever top board I and the electromagnet spring is housed, the right-hand member of lever top board II is equipped with permanent magnet, and be coupled to electromagnet with spring, and the unlatching shift fork is housed on the square shaft of catch, the middle upper part of moving lock housing is equipped with knob, fixing plectrum on the knob, on the back shroud of moving lock housing, install and open axle, hinge connection plectrum in the middle of the unlatching axle, left end is fixed a cam, open axle and be coupled to tapered end, the microswitch that links with controller is housed on the back shroud by flat axle.

The utility model has the advantages that having double anti-theft opens insurance, use mechanical type tapered end and electronic romote-controller (or password) simultaneously, having overcome existing electronic lock is having under the electric situation with key or all openable shortcoming of remote controller (or password).The utility model can be controlled with the supporting realization of security system central authorities.

Below with reference to accompanying drawing the utility model is described in further detail.

With reference to Fig. 1,2,3 a square tongue of left end solid welding [2] and two round tongues [4] at sliding panel [7], sliding panel [7] is coupled to the left end of moving lock housing [8] with extension spring [3], the U type gathering sill at sliding panel [7] right-hand member middle part cooperates with the spiral shell axle [11] on being fixed in bottom lining plate [18], tongue [5] is bumped in left end installation at bottom lining plate [18], left upper end hinge connection lever baffle plate [10], lever baffle plate [10] is coupled to bottom lining plate [18] with stage clip [6], the right-hand member of bottom lining plate [18] is installed electromagnet [17], upper right side hinge connection lever top board [13], lower right hinge connection thick stick Du top board [14], between the B end of lever top board [13] and electromagnet [17] spring [16] is housed, the right-hand member of lever top board [14] is equipped with permanent magnet [15], and is coupled to the C end of electromagnet [17] with spring [36].The coil two of electromagnet [17] is terminated at controller, the unlatching shift fork [9] that can stir sliding panel [7] is housed on the square shaft of catch [19], the middle upper part of moving lock housing [8] is equipped with knob [23], knob [23] is gone up fixedly plectrum [24], be shaped on two claws [32] on the plectrum [24], [33], on the middle upper part of the back shroud [21] of moving lock housing [8] and knob [23] coaxial position, install and open spool [27], open the middle hinge connection plectrum [26] of axle [27], left end stationary cam [25], unlatching axle [27] is coupled to tapered end [28] back shroud [21] by flat axle [34] and is fixed in spiral shell axle [11] by screw [22], microswitch [31] is loaded on the back shroud [21], be positioned at right-hand (as Fig. 3) of opening axle [27], and link with controller.

When door lock is in the normal locking states of Fig. 1, having under the electric situation, use a teleswitch outdoors (or password) makes the coil electricity of electromagnet [17], and electromagnet [17] attracts lever top board [13] to break away from sliding panel [7], rotates handle [29] and just door can be opened; When utilizing key [30] when opening the door, can only stir plectrum [26] with key [30] counter clockwise direction rotating cam [25] 360 degree, at plectrum [26] shifting lever top board [13] before, cam [25] touches microswitch [31] earlier, make the coil reversal connection energising of electromagnet [17] by controller, changed the polarity of electromagnet [17], attract the permanent magnet [15] on the lever top board [14], lever top board [14] is rotated counterclockwise withstand sliding panel [7], even pushing lever top board [13], plectrum [26] breaks away from sliding panel [7], swing handle [29] can not make lock open, and is therefore having under the electric situation, must open the door with remote controller (or password).Under no electric situation, counterclockwise stir plectrum [26] and cam [25] with key [30], revolve three-sixth turn, the claw of plectrum [26] pushes lever top board [13] makes it break away from sliding panel [7], and just available handle [29] opens the door.Available knob [23] counterclockwise rotates 90 degree in the door, makes plectrum [24] back down lever top board [13] or with remote controller (or password), makes lever top board [13] disengaging sliding panel [7], and just available handle [20] opens the door.Rotate handle [20] or [29] when opening the door, opening shift fork [9] makes sliding panel [7] drive circle tongue [4], square tongue [2], enter moving lock housing [8], then bump tongue [5] and under the effect of stage clip [6], eject moving lock housing [8], stage clip [6] makes lever baffle plate [10] block sliding panel [7] simultaneously, reach pre-lock state, as long as shut the door after you, lock shell [1] bumps and bumps tongue [5] promotion lever baffle plate [10] disengaging sliding panel [7], sliding panel [7] moves to left under the effect of extension spring [3], make round tongue [4], square tongue [2], enter lock shell [1], make door be in locking states.

Open axle [27] when rotating with the key clockwise direction, when making plectrum [26] push down lever top board [13] (as shown in Figure 3), (or password) indoor knob [23] even use a teleswitch, can not make lever top board [13] break away from sliding panel [7], lock is opened, in this case, have double insurance function and Men Nei and can not open function.Have only from using common use of key [30] and remote controller (or password) could open door lock outdoors.Turn 90 degrees when clockwise direction revolves knob [23], make plectrum [24] block lever top board [13], then outdoors with all opening with remote controller in key and remote controller (or password) or the door.When counterclockwise knob [23] is revolved and turn 90 degrees, make plectrum [24] back down lever top board [13], then door be in open, with off status, only need to rotate handle [20] or [29] and just can open the door.
