Description
1, technical field:
The utility model relates to a kind of tapered end, relates in particular to a kind of primary and secondary pearl conversion locking cam.
2, background technology:
At present, the key that tapered end disposed on the market is all the same, when user's house finishing or when new door lock is installed,, therefore not enough by security performance easily by people's copy key, tapered end does not have dust-proof mechanism on the market in addition, because tapered end is engineering goods, when too much dust enters tapered end, causes tapered end not open, so influence the function of use of tapered end, shorten its application life.
3, summary of the invention:
The purpose of this utility model provides a kind of primary and secondary pearl conversion locking cam, and it makes the more perfect function of tapered end in the increase basis conversion spoon mechanism and the dust cap mechanism of original tapered end.
The utility model is achieved by the following technical solution: it comprises tapered end, lock core, driver blade, key, be installed in the inside, hoodle hole last sub-pearl, go up female pearl, sub-pearl and time female pearl down, be provided with conversion spoon mechanism in the inside, hoodle hole, be provided with dust cap mechanism in the front of lock core, the inside of tapered end, wherein this conversion spoon mechanism comprises steel ball, this steel ball is installed in sub-pearl and down between the sub-pearl, is being positioned at same cross section, is having the steel ball hole in a certain position on the surface of lock core with steel ball; This dust cap mechanism comprise base, on roll bar, roll bar, spring and ball down, the front of base has keyhole, on the back of keyhole, base, have chute, each is communicated with a ball hole in the both sides of chute, ball hole is equipped with ball, on roll bar and roll down bar and be installed in inside the chute, ball and on roll bar and under roll spring be installed between the bar, base is installed in the front of lock core.
The utility model compared with prior art has following advantage: 1, adopt dust cap mechanism, dust is not easy to enter tapered end, has improved the working environment of tapered end, reduces the fault of tapered end, prolongs the life-span of tapered end; 2, adopt conversion spoon mechanism, increase security of products, make product meet user's requirement more, a lock often has several keys, wherein key be when using for the first time just effectively, can not open tapered end more later on, other several keys then can be opened; So user's finishing or replacing are just felt more relieved, are made things convenient for.
4, description of drawings:
Below in conjunction with accompanying drawing the utility model is done detailed explanation:
Fig. 1 is a structure master map of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the B-B sectional view of Fig. 1.
5, the specific embodiment:
As Fig. 1, Fig. 2, shown in Figure 3, the utility model comprises tapered end (1), lock core (2), driver blade (3), key (4), be installed in the last sub-pearl (5) of the inside, hoodle hole (19), go up female pearl (6), sub-pearl (7) and female pearl (8) down down, be provided with conversion spoon mechanism in hoodle hole (19) the inside, front in lock core (2), the inside of tapered end (1) is provided with dust cap mechanism, wherein this conversion spoon mechanism comprises steel ball (9), this steel ball (9) is installed between sub-pearl (5) and the following sub-pearl (7), is being positioned at same cross section with steel ball (9), a certain position on the surface of lock core (2) has steel ball hole (10); This dust cap mechanism comprises base (11), on roll bar (12), under roll bar (13), spring (14) and ball (15), the front of base (11) has keyhole (16), back in keyhole (16), have chute (17) on the base (11), each is communicated with a ball hole (18) in the both sides of chute (17), ball hole (18) is equipped with ball (15), on roll bar (12) and under roll bar (13) and be installed in chute (17) the inside, ball (15) and on roll bar (12) and under roll spring (14) be installed between the bar (13), base (11) is installed in the front of lock core (2).
The main effect of conversion spoon mechanism is: make product meet user's requirement more, a lock often has several keys, wherein key be when using for the first time just effectively, can not open tapered end more later on, and in addition several keys to use for the first time be not have effectively, competence exertion effect after above-mentioned nonrecoverable key is opened tapered end, like this purpose of She Zhiing be when the user after finishing is during new house, for fear of being taken the key configure by others.Its operating principle is as follows: when opening tapered end for the first time, make the steel ball (9) of one of them the inside, hoodle hole enter the inside, steel ball hole (10), the differential of this hoodle hole changed, the hoodle of the height of the tartar on the therefore original key (4) and the inside, this hoodle hole does not just match, and causes and can not open.
And the time, roll bar (12) in the dust cap mechanism, roll bar (13) down and block keyhole (16), when inserting key (4), return will on roll bar (12), roll bar (13) down and squeeze and open, when extracting key (4) out, roll bar (12), roll bar (13) down and block keyhole (16) making under the effect of spring (14).
