Abstract
The utility model provides a theftproof elastic ball lock. The utility model is characterized in that a lock core sleeve of which the thickness is 0.3 mm less than that of an elastic ball is additionally arranged between a lock shell and a lock core of the existing elastic ball lock; one elastic ball on a top ball of the rest of elastic ball groups is changed into a spherical elastic ball except a main open elastic ball group, the thicknesses of a second and a third plat balls of the main open elastic ball group are 0.3 mm less than that of the lock core sleeve, and the diameter of the third plat ball is 0.1 mm less than that of an elastic ball in the same group; the back end of the lock core sleeve is provided with an arc notch, and a raised head is correspondingly arranged on the lock core. The lock is used, and the condition that a universal key is used for unlocking in a ball picking method can be effectively avoided. The utility model has the advantages of simple structure and convenient use.
Description
The utility model belongs to the lock class, particularly a kind of antitheft cylinder lock with balls tapered end of using MASTERKRY to unblank of preventing.
In prior art, the structure of the tapered end of cylinder lock with balls mainly is made up of lock housing (1), lock core (2), sword iron (3), flat pearl (4), the decorative pearl on top of an official cap (5), decorative pearl on top of an official cap spring (6) and positioning bead (7) as shown in Figure 1.Because its hoodle is a truncated, and between the hoodle hole certain free gap must be arranged, this structure is easy to use MASTERKRY that lock is opened.When using MASTERKRY to unblank, earlier live lock core port with a little hook, and pull towards the direction of unblanking, be positioned at the compressing (as shown in Figure 2) that unlatching face flat pearl (4) up and down will be subjected to lock housing (1) and lock core (2) this moment, in several groups of hoodles, must there be one group hoodle to be pressed the most tightly, the unlocking person front end is that the MASTERKRY that colludes shape is inserted in the lock core (2), can find one group of the tightest hoodle with sensation, should organize hoodle then rises, as long as flat pearl (4) is crossed unlatching face and enters lock housing (1) when interior, the urgent situation of this group just obtains discharging, lock core (2) naturally again deflection a bit.At this moment, this group flat pearl (4) of being chosen up can not drop in the hoodle hole of lock core (2) again.Subsequently, in several groups of hoodle groups of remainder, will inevitably produce one group again and be in the most urgent state, as aforementioned activities, again the flat pearl (4) of this group is chosen in the lock housing (1), choose like this one group by one group, just on the flat pearl (4) of each group can being chosen in the lock housing (1), make lock housing (2) not be subjected to flat pearl (4) restriction, lock can be opened.Existing problems are not resolved so far yet hereto, and stolen phenomenon is happened occasionally.
The purpose of this utility model is to provide a kind of easy manufacturing, and is easy to use, can prevent the antitheft cylinder lock with balls tapered end that uses MASTERKRY to unblank.
Above-mentioned task realizes by this way: as shown in Figure 3, this tapered end is identical with prior art, include lock housing (1), lock core (2), sword iron (3), flat pearl (4), the decorative pearl on top of an official cap (5), decorative pearl on top of an official cap spring (6) and positioning bead (7), but done such improvement;
A, set up a lock core cover (8) between lock housing (1) and lock core (2), its thickness wants little 0.3 millimeter at least than hoodle hole (13) diameter, and positioning bead (7) is arranged on the unlatching face between lock housing (1) and the lock core cover (8);
B, establish 1～2 group of master and open hoodle group (14), this group is made up of the decorative pearl on top of an official cap (5) and the 3 flat pearls of joint (4), the diameter of the 3rd flat pearl of joint (4) than extremely when young 0.1 millimeter of other hoodle diameter on the same group, second, third thickness that saves flat pearl (4) than extremely when young 0.3 millimeter in lock core cover (8).
C, remaining hoodle group are three joint hoodles, and a hoodle above the decorative pearl on top of an official cap (5) is a pearl shape hoodle (9);
D, have the breach (10) that a radian is not more than 90 ° in the rear end of lock core cover (8), on the fixed cap (11) that links with lock core (2), be provided with a plush copper (12) corresponding to the breach center.
Fig. 1 is existing cylinder lock with balls tapered end internal structure cross-sectional schematic.
Fig. 2 is lock core inner hoodle view that suffers oppression when being reversed.
Fig. 3 is the in-built isometric cutaway view of the utility model.
Fig. 4 is along the sectional view of A-A line among Fig. 3.
The utility model can prevent that the principle of using MASTERKRY to unblank from being such: as aforementioned, when using MASTERKRY to choose main unlatching hoodle group (14) earlier, when flat pearl (4) is pushed up to lock core cover (8), pull under the twisting resistance effect that lock core (2) produced colluding for a short time, all the other spherical hoodles (9) of several groups are easy to be pressed in the lock core cover (8).At this moment, lock core cover (8) then is subjected to positioning bead (7) with lock housing (1), spherical hoodle (9) and main flat pearl (4) of opening the hoodle group are limited, lock core cover (8) can not rotate, lock core (2) is then rotatable, owing to be subjected to the restriction of lock core cover (8) breach (10) and plush copper (12), lock core (2) can only left-right rotation 45 °, form vacation and open state, lock can not be opened.If during with MASTERKRY elder generation toe lift shape hoodle group, even spherical hoodle (9) is chosen in the lock core cover (8), in case unclamp MASTERKRY, spherical hoodle (9) must fall, and the flat pearl at its top still can be pinned lock housing (1) and lock core cover (8).In addition, because the diameter of second the flat pearl (4) in the main unlatching hoodle group is smaller, still be in active state.The flat pearl at its top will lock housing (1) and lock core cover (8) pinning.Have only and use the key that matches, make the peaceful pearl of spherical hoodle (9) (4) flush in unlatching face and lock could be opened.In sum, when using MASTERKRY to unblank, no matter choose that group hoodle earlier, all lock can not be opened, thereby can overcome the defective of prior art effectively.In addition, the utility model is compared with existing ball cylinder, and structure is also uncomplicated, make easily, and also easy to use.
The utility model is suitable for making door lock and takes out cabinet lock etc.
When implementing the utility model, desirable 3.6 millimeters of hoodle hole (13) diameter, spherical hoodle (9) diameter are 3.5 millimeters, and lock core cover (8) thickness is 3 millimeters, and the 3rd joint flat pearl (4) diameter is 3.4 millimeters, and second, third thickness that saves flat pearl is 2.5 millimeters.
