Implement cylinder lock capable of preventing tool from being opened provided by the invention, because the structure uniqueness, the course of work is different from the traditional design of domestic and international mechanical lock, has the special performance of desirable secret key amount and reliable and stable precautionary technology unlatching.Can effectively refuse any type of instrument especially and enter key channel and illegally open, thereby can improve the anti-theft security performance of tapered end and lockset greatly.
In conjunction with the accompanying drawings and embodiments, further specify characteristics of the present invention and advantage, in the accompanying drawing:
Fig. 1 is the structural representation of cylinder lock capable of preventing tool from being opened of the present invention.
As shown in Figure 1, lock head structure of the present invention mainly is made up of lock housing 1, lock core 2, a plurality of pellet shot from a slingshot (51-53), steel ball 4, spring 6 combinations etc.Between lock housing 1 and lock core 2, be formed with a plurality of passages or groove (3), these passages (groove) are divided into internal channel and general passage.The passage 31 that internal channel refers to the most inboard (from the key upstream end farthest), the rest channels in the internal channel outside is general passage, and four general passage 32-35 are arranged among Fig. 1.Lock core 2 external diameters can be 14.5 millimeters, than routine only go out 1.5 millimeters greatly, guarantee the compatibility that it is enough.The radial thickness that is close to the base portion 23 of one with lock core 2 is 5.5 millimeters, and conventional having only below 4 millimeters or 4 millimeters, therefore improved the mechanical strength of tapered end, and optional the longest constant pellet shot from a slingshot group passage of conduct in can each the general passage in tapered end, in pack into 3 millimeters sizes steel ball 4 and 7.5 millimeters high middle joint pellet shot from a slingshot 51, this pellet shot from a slingshot is as the highest pellet shot from a slingshot of tapered end, the minimum tooth position of corresponding key, and this design has constituted architecture basics of the present invention.
The lock core keyhole divides spoon tooth and the basic two parts of spoon, and spoon tooth hole is 5 millimeters, and apart from being 0.5 millimeter, it is differential up to 11 magnitudes by standard level; The spoon datum hole is 4 millimeters, is provided with side's spoon grooved rail of a super center line in a side of spoon datum hole, the safety of shielding pellet shot from a slingshot group, and tool using can not enter any instrument when opening from here.
In the tapered end of embodiments of the invention, having established 5 groups of pellets shot from a slingshot altogether sets up separately and does in the passage, wherein one group is constant long marble (5 millimeters specifications of depth of threat), and can shift one's position in first, second, third and fourth group, and its effect is to stop that the standard opener enters lockhole and carries out open operation.So-called conventional tool is meant that the camber of opener can place all pellets shot from a slingshot the unlatching tangent plane respectively with length and do not interact in open operation.Because the restriction of constant long marble and lockhole activity point of view, therefore, the instrument that can enter lockhole does not all rise to whole pellets shot from a slingshot the unlatching tangent plane, makes it can not reach purpose of opening.
In the tapered end of embodiments of the invention, the spacing of every group of pellet shot from a slingshot is 5 millimeters (external product adopts 4 to 4.5 millimeters usually), key tooth flower adopts the angle of 60-70 degree scope, preferably 65 spend angles (being generally an angle of 90 degrees), can reach the theory design that the highest and minimum tartar are arranged with the tartar that guarantees 5 millimeters height of pellet shot from a slingshot group arranged side by side, make theoretical secret key amount identical with actual secret key amount.
In the tapered end of embodiments of the invention, as shown in the figure, every group of pellet shot from a slingshot established upper, middle and lower three joints, wherein, following joint pellet shot from a slingshot is a steel ball 4, the principle of utilizing steel ball to roll, make the highest key tooth flower at 60-70 ° of angle, best 65 ° of angles, can on the level amount of 5 millimeters height, pass in and out lockhole freely.Control pellet shot from a slingshot joint (middle joint pellet shot from a slingshot 52, on save pellet shot from a slingshot 53) has two kinds of naked body and abnormity, can use wherein any or both combination.The abnormity pellet shot from a slingshot is only done complementary strick precaution and is used, the naked body pellet shot from a slingshot then can guarantee this tapered end with the reasonability of key routing motion, can increase the application life of lockset like this, and open smooth and easy, use with the passing of time and failsafe, thereby further guarantee the feasible and integrality of technical solution of the present invention.
The secret key amount of tapered end of the present invention is higher, owing to adopt steel ball rolling principle, and on the standard level distance basis of (0.5 millimeter), the an amount of progression that increases, and suitably having drawn back the pellet shot from a slingshot spacing and the small spoon tooth angle that contracts, every group of pellet shot from a slingshot adopts three joint (section) structures, and be identical with practice spoon amount to guarantee theoretical spoon amount.On the other hand, the ad hoc one group of constant long marble of tapered end of the present invention to refuse the lockhole that enters of illegal opener, has guaranteed that further each lock all can reach the purpose of the unlatching of taking precautions against the technical instrument of intrusive mood.
