Description
Technical field
The utility model relates to anti-theft lock device, particularly the spacing anti-theft lock of a kind of pellet for mechanical anti-theft lock.
Background technology
At present, various locksets in people's daily life, such as door lock, padlock etc., usual employing be traditional cylinder lock core type lockset, the movement of pellet in marble hole is utilized to lock lockset, but the burglarproof function of lockset of this structure is poor, can be opened easily when running into the unlocking tools such as thief use master key, the principle of unblanking of master key is that the length of each key bit of corresponding lock core marble is made the degree of depth identical with internal cylinder marble hole, master key is injected in keyhole, instigateeing up and down just all can eject in outer lock core marble hole by pellet in internal cylinder marble hole, rotation master key and rotatable internal cylinder are unblanked.Therefore, existing traditional cylinder type lockset theftproof performance is very weak, and crisis is to the property safety of people.
Summary of the invention
The purpose of this utility model is to provide the spacing anti-theft lock of a kind of pellet, and the anti-theft feature solving traditional lock cylinder lockset is weak, easily by problem that master key is pried open.It can effectively prevent from adopting master key to unblank, and structure is simple, and theftproof performance is strong.
The technical solution of the utility model is: the spacing anti-theft lock of a kind of pellet, comprise outer lock core and internal cylinder, compression spring is assembled with in multiple outer lock core marble hole and internal cylinder marble hole, locking pellet and interior pellet, its technical essential is: the shape of at least one outer lock core marble hole is stairstepping duct, stairstepping duct segmentum laterale is aperture, medial segment is macropore, step is formed between aperture and macropore, locking pellet is arranged in macropore, locking billiards diameter is greater than the hole diameter in stairstepping duct, the large hole depth in stairstepping duct is less than locking pellet and interior spring length sum, the opposite side inside corresponding with outer lock core marble hole of outer lock core is provided with outer lock core pellet installing hole.
The spacing anti-theft lock of described pellet is in-line or cross.
The outer lock core marble hole shape of the adjacent phase of described cross lock core is described stairstepping duct.
Described shape is the rearmost position that the outer lock core marble hole in stairstepping duct is arranged on lockhole axis.
The good effect that the utility model has is: little with exit orifice owing to adopting, the outer lock core marble hole in the stairstepping duct that endoporus is large, when running into use master key and prizing lockset, when locking pellet slides into stepped locations laterally, this step can limit the outwards movement of locking pellet, namely to locking pellet outwards movement carry out spacing, and be less than locking pellet and interior spring length sum due to the large hole depth in stairstepping duct, when locking pellet and withstanding on outer lock core marble hole step place, interior pellet is also locked pellet simultaneously and blocks, therefore the body of interior pellet can not all enter in outer lock core marble hole, part body is still had to stay in internal cylinder marble hole, play the effect of locking internal cylinder, prevent lockset from being pried open by master key, improve the theftproof performance of lockset, the opposite side inside corresponding with outer lock core marble hole of outer lock core is provided with outer lock core pellet installing hole, locking pellet can be inserted in installing hole when assembling locking pellet, through being inserted in the macropore of outer lock core marble hole after installing hole, its structure is simple, with low cost, be easy to manufacture and assembling.

In figure, sequence number illustrates: pellet, 7 installing holes, 8 outer lock core marble holes, 9 internal cylinder marble holes, 10 apertures, 11 macropores, 12 keyholes, 13 master keys in 1 internal cylinder, 2 outer lock cores, 3 compression springs, 4 steps, 5 locking pellets, 6.
Detailed description of the invention
Concrete structure of the present utility model is described in detail according to Fig. 1 ~ 5.As illustrated in fig. 1 and 2, the spacing anti-theft lock of a kind of pellet, comprise outer lock core 2 and internal cylinder 1, outer lock core 2 is provided with multiple outer lock core marble hole 8, internal cylinder 1 is provided with multiple internal cylinder marble hole 9, outer lock core marble hole 8 is communicated with corresponding internal cylinder marble hole 9, in lock core marble hole 8 and internal cylinder marble hole 9, ecto-entad is assembled with compression spring 3, locking pellet 5 and interior pellet 6 outside, locking pellet 5 is for the rotation in lock-out state limit internal cylinder, internal cylinder marble hole 9 is inserted in the inner of locking pellet 5, namely be in the lock state, interior pellet 6 also referred to as pins pellet, for key bit corresponding matching, wherein, multiple outer lock core marble hole 8 has multiple or at least one shape to be stairstepping duct, stairstepping duct segmentum laterale is straight tube shape aperture 10, medial segment is straight tube shape macropore 11, step 4 is formed between aperture 10 and macropore 11, locking pellet 5 is arranged in macropore 11, locking billiards diameter is greater than aperture 10 diameter in stairstepping duct, the fixed end of compression spring 3 is arranged in aperture 10, the free end of compression spring can stretch into promotion locking pellet in macropore and move in macropore, macropore 11 degree of depth in stairstepping duct is less than locking pellet 5 and interior pellet 6 length sum, when locking pellet 5 and withstanding on outer lock core marble hole step 4 place, interior pellet 6 is also locked pellet simultaneously and blocks, and the body of interior pellet 6 all can not to enter in outer lock core marble hole 8, part body is still had to stay in internal cylinder marble hole 9, the opposite side external lock core corresponding with outer lock core marble hole of outer lock core is provided with outer lock core pellet installing hole 7, locking pellet 5 can be inserted in installing hole 7 when assembling locking pellet, through being inserted in the macropore of outer lock core marble hole after installing hole, by installing hole shutoff after assembling completes.This installing hole also can be communicated with internal cylinder marble hole by straight-cylindrical outer lock core marble hole and to form, can stacking pressure spring, locking pellet and interior pellet simultaneously, plays locking action.This lock core can be used on various lockset.
As shown in Figure 3, further, the spacing anti-theft lock of pellet can be arranged to in-line, the spacing anti-theft lock of in-line pellet arranges outer lock core marble hole 8 and internal cylinder marble hole 9 in the symmetrical both sides of keyhole 12, form in-line, as shown in Figure 4, the spacing anti-theft lock of pellet can be arranged to cross, the spacing anti-theft lock of cross pellet is symmetrical arranged outer lock core marble hole 8 and internal cylinder marble hole 9 at keyhole 12 in criss-cross four phase places, form cross, stairstepping duct described in adopting at least one outer lock core marble hole shape of the adjacent phase of cross lock core.
As illustrated in fig. 1 and 2, further, the outer lock core marble hole in described stairstepping duct is arranged on the rearmost position of multiple outer lock core marble holes of lockhole axially-aligned.
The course of work: as shown in Figure 5, when using master key 13 to prize lockset, interior pellet 6 in internal cylinder marble hole is pressed towards to be had in stairstepping duct outer lock core marble hole 8, locking pellet 5 compression pressure spring 3 under the promotion of interior pellet, slide into stepped locations laterally, this step 4 can limit the outwards movement of locking pellet, namely to locking pellet outwards movement carry out spacing, and be less than locking pellet and interior spring length sum due to the large hole depth in stairstepping duct, when locking pellet and withstanding on outer lock core marble hole step place, interior pellet is also locked pellet simultaneously and blocks, therefore the body of interior pellet can not all enter in outer lock core marble hole, part body is still had to stay in internal cylinder marble hole, play the effect of locking internal cylinder, prevent lockset from being pried open by master key, improve the theftproof performance of lockset.
