Description
The utility model relates to a kind of burglar alarm cipher door lock.
At present, family expenses door lock commonly used generally is made of parts such as lockhole, lock core and latches, by key operated.Because key is lost easily, is stolen or prepare, duplicates, as long as anyone obtains the key that cooperates with this door lock, just can open the door and enter the room, and the frame for movement of this door lock core is comparatively simple, the robber utilizes simple tool to pry open or to destroy, therefore this door lock security performance is not high, and the user must carry key, inconvenience simultaneously.At above-mentioned shortcoming, the someone has designed multiple cipher door lock now, but the complex structure that these cipher door locks have, the group/cording quantity that has is few, and theftproof performance is bad, and practicality is not high.
The purpose of this utility model be design a kind of need not be key operated, combination type family expenses burglar-proof alarm door lock that security performance is high.
For this purpose, the utility model adopts following design scheme: combination type family expenses burglar-proof alarm door lock, by multilayer password rotating disk, lock core, the tapered end and the alarm that are provided with movable latch are formed, and lock core comprises lock core body, be located at rotatable the turn-taking that is connected with the password rotating disk in the lock core body, be located at the rotating shaft in the lock core body, rotating shaft one end is positioned at the password rotating disk and is made as handle outward, and the other end is connected with tapered end stirs movable latch.Be provided with a wedge-shaped slot in the middle of the rotating shaft, spacer pin one end is located in the wedge-shaped slot, and the other end peaks on the lock core body wall by the bullet end, turn-takes to be provided with breach, and alignment pin is provided with the double wedge that breach cooperates; Turn-taking is provided with armature contact, is provided with corresponding with it fixed contact in the lock core body; An input of alarm is connected with fixed contact with armature contact, another input.
This door lock adopts the password rotating disk to drive and turn-takes, by the spacer pin control rotating shaft, and the switching of control tapered end.The group/cording quantity of password rotating disk can reach hundreds thousand of kinds, and door lock is not provided with lockhole, and security performance is fine.Do not knowing as the stranger to stir the password rotating disk under the situation of password, just can trigger alarm and produce alarm signal.This door latch structure is reasonable, and is easy to use, practical.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1, be the user mode figure of the utility model combination type family expenses burglar-proof alarm door lock.
Fig. 2, be the parts explosion of door lock shown in Figure 1.
Fig. 3, be the structure sectional view (blocking) of door lock shown in Figure 1.
Fig. 4, be another sectional view of structure (opening) of door lock shown in Figure 1.
Fig. 5, be the rotating shaft of door lock shown in Figure 1 and the structural representation of spacer pin.
As shown in Figure 1 and Figure 2, combination type family expenses burglar-proof alarm door lock comprises 4 password rotating disks 1, and password rotating disk 1 is arranged at outside the door leaf by fastener 2.Every rotating disk front is provided with the 0-9 numerical ciphers, is provided with alphabetical password between numerical ciphers, and 4 password rotating disks can form hundreds thousand of combinations.The back side of password rotating disk 1 is provided with a circle groove 27, is provided with aperture 20 in the position corresponding with the front password.
Lock core is arranged at and comprises lock core body 3 in the door leaf, lock core body 3 is the cylindrical shape of front opening, its inside is provided with 4 layers of coaxial circles tubular holder 4, turn-take for 4 and 5 be sheathed on the tongue of holder 4 23, rotatable by groove 22,5 front ends of turn-taking are provided with a protruding pin 21, and 5 front end sleeves of turn-taking are located in the groove 27 at the password rotating disk back side, and protruding pin 21 is inserted in the aperture 20 of password rotating disk 1, like this, 4 password rotating disks can drive the connected rotation of turn-taking respectively.The rear end of turn-taking is equipped with breach 6.Rotating shaft 7 is located in the axis of lock core body 3 in the heart, and its front end stretches out from the fluting of fastener 2 and forms handle 8, and tapered end 9 inside of being located at behind the door leaf are stretched in rear end 10, and rotating shaft 7 can be stirred the latch 26 in the tapered end, thereby reaches the purpose of open and close door.The stage casing of rotating shaft 7 is provided with a wedge-shaped slot 25, offer hole 11 on the holder 4, installing spacer pin 12 in the hole, the lower end of spacer pin 12 is wedge shape, cooperate with wedge-shaped slot 25, spacing pin is provided with 4 row's double wedges 13, and double wedge 13 shapes cooperate with above-mentioned breach 6, and the upper end of spacing pin is located on the inner tube wall of lock core body by spring 24 tops.
As shown in Figure 3, every rear end of 5 of turn-taking is coated with and is covered with a circle insulation wear-resistant material layer 14 as enamel etc., be provided with on the wear-resistant material layer 14 and 15,4 fixed contacts 16 of armature contact of 5 conductings of turn-taking are fixed in the lock core body in insulation, separately with turn-take on insulating layer 14 contact.In 4 fixed contacts 16 one is connected with a pin of alarm 18 by lead 17, and another pin of alarm 18 and the lock core metalwork of this door lock company lead.
The user desires to unblank, only need to stir password rotating disk 1 by the password of setting, password rotating disk 1 drives 5 rotations of turn-taking, breach 6 is aimed at the tooth 13 of spacing pin 12, forward spur handle 8 with hand this moment, and spacer pin 12 is deviate from from the wedge-shaped slot 25 of rotating shaft 7, and rotating shaft 7 is free to rotate, turn handle 8 and just can push latch 26 aside, make a unlatching.If do not know that the people of password arbitrarily stirs password rotating disk 1, because misalignment password, therefore breach 6 can't be aimed at tooth 13, handle 8 can not rotate, can't open the door, and stir in the process, connect when 5 rotations of turn-taking make armature contact 15 and fixed contact 16 at it, just can trigger alarm 18 and produce alarm signal, remind the owner in house or the security authority of residential block.
The user sets or change the door lock password can adopt following steps: after stirring password rotating disk 1 aligning password, 45 ° of draw-out handle rotations, unclamp hold-down screw 19, unload fastener 2 and handle 8, make the password rotating disk 1 and 5 disengagings of turn-taking, reorientate aperture 20 and protruding pin 21, then promptly reset new password in the assembling.
