Abstract
The utility model relates to an integrated key cylinder of the night clock and relates to the key cylinder and the key related with the night lockset, in particular an integrated key cylinder and key with better safety function. The utility model has at least two key cylinders with the billiards hole and the lead hole for the key. The key cylinder is translated in the billiards positioning device though the billiards and the positioning device. The key rack has a former opening tooth, a back opening tooth and an interfering tooth. The lock is opened as follows: Whirl the first key cylinder to the second key cylinder with the former opening tooth, and whirl the second key cylinder with the key to open the door. The utility model uses the traditional and common technique to realize the multilevel key cylinder opening device, and achieve the safer target with complex lock opening process.
Description
Affiliated technical field: the utility model relates to the pin tumbler lock of huge numbers of families' safety and lock core and the key relevant with cylinder lock set, specifically is meant better combined cylinder of spring lock of a kind of security performance and key.
Technical background: at present the safe spring lock of widely used various types of shape is in the lock core of each lock one group of single-stage lock core only to be installed, and inserts the lock core rotary locking cylinder with key and realizes unblanking.
Summary of the invention: the utility model provides a kind of combined cylinder of spring lock to solve the technical scheme that its technical problem takes to be: at the lock core of design and installation more than 2 or 2 in the combined lock core.Lock core is cylindrical, is provided with pellet shot from a slingshot hole and the guide groove or the guide hole that can insert key above, utilizes the positioning function of pellet shot from a slingshot and pellet shot from a slingshot positioning body that angle of the mutual dislocation of each lock core is contained in the pellet shot from a slingshot positioning body.Realize the multistage lock core unlocking mechanism of combined lock core.The beneficial effects of the utility model be technology tradition, technology general, similar be two sealed one, realize that multistage lock core unlocking mechanism reaches safer order ground with the complicated process of unblanking.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further,
Figure: be the novel simplified structure diagram of this reality.
Among the figure, 1. the 2nd grade of lock core, 2. the 1st grade of lock core, 3. pellet shot from a slingshot positioning body, 4. key.
Specific embodiment:
In the drawings, 1. the 1st grade of lock core (2), second level lock core (1) is packed in the lock core locating hole that pellet shot from a slingshot positioning body (3) is provided with in order, pellet shot from a slingshot, spring are installed in the pellet shot from a slingshot hole of pellet shot from a slingshot positioning body (3), utilize the positioning function of pellet shot from a slingshot and pellet shot from a slingshot positioning body that two-stage lock core (1, the 2) angle that misplaces mutually is installed in the pellet shot from a slingshot positioning body (3), the outside of pellet shot from a slingshot positioning body (3) becomes combined lock cylinder assembly by containing shell parcel (contain among the shell figure and omit).The tooth bar of (Z1-Z2-Z4) of key (4) is called A row tooth bar, (Z1) the tooth section is identical with the number of teeth of (Z4) tooth section, tooth pitch is identical, profile of tooth is identical, act on the 1st grade and the 2nd grade of lock core, (Z2) the tooth section is an interfering tooth and (Z1) tooth section acts on the 2nd grade of lock core, (Z3) to belong to together be interfering tooth to the tooth of tooth section, is (Z1) tooth section and (Z2) summation of tooth hop count, acts on the lock core of the second level, (Z0) be zero number of teeth, generally do not exceed two row in the A level tooth bar design of key.When A row tooth bar (Z1) the tooth section of key is inserted the 1st grade of lock core and rotated the relative angle of 2 grades of lock cores of first order lock core to the when unblanking, continue a key and insert the 2nd grade of lock core and rotate the two-stage lock core simultaneously with key and could realize unblanking.
Claims (2)
1, its key of having the lock core more than 2 or 2 and being complementary of a kind of combined cylinder of spring lock with it, its feature: be that angle of mutual dislocation is installed in the pellet shot from a slingshot positioning body between lock core (1), the lock core (2), spring and pellet shot from a slingshot are contained in the pellet shot from a slingshot positioning body and the pellet shot from a slingshot hole associated on the lock core.
2, combined cylinder of spring lock according to claim 1, its feature: the A row tooth bar of key (4) is provided with (Z1), (Z2), (Z4) tooth section, wherein (Z1) tooth section is identical with the number of teeth, tooth pitch, the flute profile of (Z4) tooth section, (Z3) number of teeth of tooth section is (Z1) tooth section and (Z2) number of teeth sum of tooth section, and tooth bar can be designed as 1 row-4 row as required.
