Abstract
The utility model relates to a cipher lock for an anti-theft door, and the utility model comprises a dial and an inner body, wherein, the dial is connected with the inner body by an inner body shaft. The inner body is composed of a locking plate, a driving disc, a bolt and a connecting rod, wherein, the driving disc and the locking plate are sheathed with the inner body shaft. The driving disc is provided with a notch, the bolt and the connecting rod are mutually hinged, and a spring is arranged between the bolt and the connecting rod. A bent is arranged at the end of the connecting rod; a stopper is arranged on the outside surface of the driving disc. A locating piece with a bar hole is arranged on the outside of the connecting rod, and the connecting rod is provided with a convex head positioned in the bar hole. The cipher lock for the anti-theft door has the advantages of easy operation, good safety performance and long service life.
Description
The invention relates to the coded lock that uses on a kind of security door.
Coded lock, particularly mechanical code lock generally are to be used for strongbox or safety cabinet.Though the situation of lock that accesses to your password is also arranged on the security door, or is the coded lock of electronic type, or be the combination of coded lock and pellet shot from a slingshot safety lock.The advantage of electronic type coded lock is to use conveniently, security performance is good, and shortcoming is to use the life-span not long, and needs often to change battery.Coded lock and cylinder lock are combined, and anti-theft effect is pretty good, and as the manual coded lock security door that Chinese patent 89201373.7 provides, it is that pellet shot from a slingshot safety lock and coded lock are installed on door, realizes locking a door by the slide mechanism that is installed between them.During use, open coded lock with password earlier, open the pellet shot from a slingshot safety lock again, twist outdoor handle at last slide mechanism is horizontally slipped, finish the function of opening the door or locking a door.Obviously, the practical operation of this security door extremely bothers, and has influenced its practical value.
The purpose of the invention provides a kind of easy to operate, mechanical type anti-theft door cipher lock that security performance is good.
This anti-theft door cipher lock comprises dial and endosome, is connected by interior axon between dial and the endosome.Locking plate, rotating plate, dead bolt and connecting rod are arranged in the endosome, and on the axon, rotating plate was provided with recess in rotating plate and locking plate were socketed in, dead bolt and connecting rod are hinged, and spring is set between them, and the end of connecting rod is provided with elbow, and this elbow can enter in the recess on the rotating plate.The rotating plate lateral surface of this anti-theft door cipher lock is provided with the retaining head, and the arranged outside spacer of connecting rod has bar hole on the spacer, the plush copper that is arranged in this bar hole is arranged on the connecting rod.
The concrete structure of the invention is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the structural representation of this anti-theft door cipher lock.
Fig. 2 is the schematic appearance of this anti-theft door cipher lock.
Below in conjunction with accompanying drawing this anti-theft door cipher lock is elaborated.
As shown in Figure 1, the structure of this anti-theft door cipher lock is the improvement of doing on the architecture basics of general insurance cabinet coded lock.Mainly comprise parts such as locking plate 3, rotating plate 5, dead bolt 4, connecting rod 6 and spring 7 in its endosome shell.Rotating plate 5 and locking plate 3 are socketed on the interior axon 12.Three of locking plate 3 general selections make the password of opening coded lock have three groups.The edge of locking plate 3 fluted 31.When the groove 31 in three locking plates 3 was in a certain location simultaneously, the lateral pin 63 on the connecting rod 6 can enter in the groove 31.Rotating plate 5 is provided with recess 51, and the end of connecting rod 6 is provided with elbow 61.After the lateral pin on the connecting rod 6 63 enters in the groove 31 of locking plate 3, rotate rotating plate 5 again, the elbow 61 of connecting rod 6 ends is entered in the recess 51 on the rotating plate 5.Like this, rotating plate 5 can drivening rods 6 and the dead bolt 4 hinged with connecting rod 6, and coded lock is opened.
As shown in Figure 2, interior axon 12 outer ends of this anti-theft door cipher lock are connected with dial 1.So rotary dial, the purpose that just can realize opening the door body.Above-mentioned this process, similar with common safety cabinet coded lock.In order to make people also can pin a body in the room and to upset the locking plate position, interior axon 12 the inners of the invention are connected with a turning wheel 9.By rotating turning wheel 9, just can achieve the above object.
The crucial part of the invention is to be implemented in the room and can directly open this coded lock by password.When just requiring lateral pin 63 at connecting rod 6 not enter in the groove 31 of locking plate 3, dead bolt 4 also can move.This is irrealizable for common safety cabinet coded lock.For this reason, the invention is the arranged outside spacer 8 at connecting rod 6, and bar hole 81 is arranged on the spacer 8, and plush copper 62 is arranged on the correspondence position of connecting rod 6.This plush copper 62 is positioned at bar hole 81 all the time.Spacer 8 has been arranged, the position of connecting rod 6 is restricted, can not be stuck.Like this, people just can directly open this coded lock in the room.The lateral surface of rotating plate 5 is provided with retaining 52, rotates rotating plate 5, and this retaining 52 can drive spacer 8, and dead bolt 4 is stretched out, so this retaining 52 has been the effects of locking a door.
In the present embodiment, between dead bolt 4 and the endosome 2 toggle mechanism is set.Toggle mechanism comprises a rotary poke rod 10 and the cam 11 that is fixed on the poke rod 10.Because spacer 8 has been arranged, by rotating poke rod 10, the cam 11 drive spacers 8 on the poke rod 10 are moved, just can realize that the people opens the operation of this coded lock in the room.
Compared with prior art, this anti-theft door cipher lock is simple in structure, and is easy to operate; Because this Anti-theft door cipher lock is the improvement of doing on the Safet puzzle lock basis, so the anti-theft security performance is good Good, long service life.
