Detailed description of the invention
Fig. 1 to Fig. 4 illustrates a kind of embodiment of the present utility model, comprise lock housing 1, lock gall 2, some the first pellets 3, the first marble spring 4, the radial direction of described lock housing 1 and lock gall 2 is provided with the first marble hole 5, lock gall 2 axial directions are provided with keyhole 21, and described the first pellet 3 comprises on first pearl 31, first time pearl 32.On described the first marble spring 4, first, pearl 31 and first time pearl 32 are arranged in the first marble hole 5 successively.The first marble hole 5 comprise pearl 31 on the first time hole of bead 52 and accommodating first of pearl 31 on accommodating first time pearl 32 and first first on the hole of bead 51.First time the hole of bead 52 is opened in lock gall 2, and the hole of bead 51 is opened in lock housing 1 on first.One end of the first marble spring 4 is resisted against on first on pearl 31, and the other end is resisted against the first marble hole bottom of lock housing, i.e. bottom, the hole of bead 511 on first.In the time of blocking, described the first marble spring 4 is all outstanding key hole walls 211 of first time pearl 32 in the time of reset mode, described lock core also comprises at least one second pellet 6, the second marble spring 7, the radial direction of described lock housing and lock gall is provided with the second marble hole 8, described the second pellet comprises on second pearl 61, second time pearl 62, and pearl 61 on described second, second time pearl 62 and the second marble spring 7 are arranged in the second marble hole 8 successively.One end of the second marble spring 7 is resisted against on second on pearl 61, and the other end is resisted against the second marble hole bottom of lock housing, i.e. bottom, the hole of bead 811 on second.The difference of described the second pellet and the first pellet is, when the second marble spring is during in reset mode, and second time pearl, the 62 retraction key hole walls 211 of the second pellet, the second pellet is a kind of retraction type pellet.
In order further to improve theftproof performance, referring to Fig. 3, second time pearl of described the second pellet is hollow bead 621.This hollow bead 621 has hollow hole 622, and the aperture of this hollow hole 622 is less than the diameter of second time pearl.The pellet of this structure, if when choosing, dial with tiny instrument, because it is hollow, instrument cannot find origin of force, therefore cannot promote this hollow bead, so just makes theftproof performance better.Even if this instrument can be soundd out hollow bead ring top 623, because ring top 623 areas are little, be difficult to use power, also easily slip in hollow hole, therefore substantially cannot promote hollow bead.Therefore, this hollow bead has improved theftproof greatly.
In order to make theftproof better, on second time pearl 62 of described the second pellet and second, the overall outline in the cross section of pearl 61 is T shape.Further improve be described the second pellet second time pearl cross section outline for T shape, the cross section outline of pearl is rectangle on second.On second time pearl and second, the global sections outline of pearl is that the benefit of T shape is: in the time of locking, pearl enters in lock gall on second, it is large that this T shape structure ensures that pearl on second snaps in contact area in lock gall, increase pearl anti-twisting property on second, strengthened destructive difficulty of unblanking.Certainly, the cross section outline of second time pearl can also be L shaped, trapezoidal etc., can reach identical effect.
In order further to improve theftproof, described lock core is along the axial front of central axis and be equipped with the first pellet, the first marble spring and the first marble hole and the second pellet, the second marble spring and the second marble hole perpendicular to positive direction.
Fig. 5 illustrates the situation of this retraction type pellet for Double-lock-core door lock.As can be seen from Figure 5, in interior lock gall 2B, do not insert key, now, first time pearl 32 of the first pellet be the retraction key hole wall 211 of second time pearl 62 of outstanding key hole wall 211, the second pellets all.In outer lock gall 2A, insert key 100, now, the pit matching with the first pellet in key promotes the first pellet and moves to lock housing direction, until pearl 31 departs from lock housing on first, the elastic protrusion matching with the second pellet in key promotes the second pellet and moves to lock housing direction, until pearl 61 departs from lock housing on second, rotate key, can unblank.
Lock housing 1 shown in Fig. 5 is made up of outer lock shell 11, the first lock gall cover 12 and the second lock gall cover 13, and the first lock gall cover 12, the second lock gall cover 13, outer lock shell 11 are set with successively from inside to outside and are affixed, and the first marble hole 5 is opened in the first lock gall cover 12 and lock gall 2.One end of the first marble spring 4 is resisted against on first on pearl 31, and the other end is resisted against on the second lock gall cover 13.The same with the first pellet situation, the second marble hole 8 is opened in the first lock gall cover 12 and lock gall 2, and one end of the second marble spring 7 is resisted against on second on pearl on 61, and the other end is resisted against the second lock gall and puts on 13.The more convenient replacing pellet of lock core or the marble spring of this structure.
Because lock core of the present utility model has the pellet of special retraction type, therefore the key matching with it is also had any different with traditional key.See Fig. 6 and Fig. 7, described key 100 comprises key main body, key main body comprises grip part 110 and the portion 120 of unblanking, described in the portion 120 of unblanking have the pit 121 matching with the first pellet, the elastic protrusion 122 that also has the second pellet of at least one and aforesaid lock core to match.There is a through hole 123 in the described portion 120 of unblanking, and this through hole 123 is for settling described elastic protrusion 122.Described elastic protrusion 122 comprises the back-moving spring 125 between two hoodles 124 and two hoodles.In order to make hoodle 124 be easy to install and do not deviate from from through hole 123, a hoodle periphery therein arranges a sleeve 126, arranges and stops step 127 at another hoodle place.While installation like this, from aperture, hoodle 124 and back-moving spring 125 are put in large one end, then overlap upper bush 126.Elastic protrusion can be also a hoodle and a back-moving spring.
If second time pearl of the second pellet in lock core is hollow bead, the diameter of the elastic protrusion in key should be between hollow hole aperture and the diameter of second time pearl.In the time that elastic protrusion compresses this hollow bead, elastic protrusion is just pressed on hollow bead ring top 623, moves thereby promote hollow bead.
In order further to increase unlocking difficulty, described elastic protrusion is arranged on the front of key or/and on the side vertical with front.The horizontal plane and the vertical plane that are key can arrange elastic protrusion.
Retraction type pellet in the utility model can be for any lock cylinder.
