The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
As depicted in figs. 1 and 2, described lock is blade lock, and blade lock comprises lock housing 1 and lock core 2, and lock core 2 is located in lock housing 1, and the upper end of lock housing 1 is stretched out in the upper end of lock core 2, establishes keyhole 22 on lock core.Be provided with the sequin storage tank 21 that radially extends in lock core, described sequin storage tank is the blade storage tank, and described blade storage tank is groove, is convenient to install vane group; In blade storage tank 21, sequin is installed, described sequin is vane group, described vane group comprises the first blade 31 and the second blade 32, be formed with the patchhole 33 corresponding with the keyhole position between the first blade 31 and the second blade 32, be provided with return unit 4 between the first blade and the second blade, described return unit is back-moving spring, have the first clamping groove on the first blade 31, have the second clamping groove on the second blade 32, the first clamping groove and the second clamping groove can be V-type, square or spherical.Have the lockpin hole 23 that is communicated with the blade storage tank radially on lock core 2, lock pin 5 is installed in lockpin hole 23, one end of lock pin 5 is the shape that coordinates with the first clamping groove and the second clamping groove, be V-type as the first clamping groove and the second clamping groove, an end of lock pin 5 is also V-type, and the first clamping groove and the second clamping groove are square, and an end of lock pin 5 is also square, be provided with bellmouth 11 on the inside of lock housing 1, the other end of lock pin is the pyramidal structure that coordinates with bellmouth 11.Last group vane group in the key direction of insertion is positioned at patchhole and is provided with engineering pearl 6, certainly, the engineering pearl also can be arranged on inserting in the hole of other vane group, and engineering pearl 6 is provided with draw-in groove 61, in the end on one group of vane group, the face that contacts with vane group is the inclined-plane in the draw-in groove holding.
In the utility model, finishing key 100 is shorter than house-owner key 101, and its short part reaches as dodging the position, and is certain, and the finishing key can be also that the end becomes L-type, as long as do not touch the engineering pearl after fitting up the key insertion.
As depicted in figs. 1 and 2, before finishing key 100 inserts, 6 holdings of engineering pearl are in the patchhole of vane group of a group bottom, at this moment, the first blade of lock pin and one group of vane group bottom and the first clamping groove of the second blade and the second clamping groove position are corresponding, and the first blade of other vane group and the first clamping groove of the second blade and the second clamping groove position are not corresponding with lock pin; To fit up key 100 after key insertion hole inserts, finishing key 100 do not touch the engineering pearl, at this moment, under the effect of finishing key 100, can make the first clamping groove of the first blade of other vane group and the second blade and the second clamping groove position corresponding with lock pin, then rotary locking cylinder, because the other end of lock pin is taper, under the squeezing action of lock core, an end of lock pin is placed to the first clamping groove and the second clamping groove, realizes the unlatching of lock.
As shown in Figure 3 and Figure 4, when house-owner's key 101 is inserted in the process of patchhole 33 through keyhole 22, the front end of house-owner's key 101 can resist engineering pearl 6, in continuing insertion process, the draw-in groove 61 of engineering pearl 6 can slip away that vane group moves downward until the upper surface of engineering pearl 6 lower than the soffit of one group of vane group bottom, at this moment, the engineering pearl can't reset.After house-owner's key inserted, the first blade of vane group and the first clamping groove of the second blade and the second clamping groove position were corresponding with lock pin, and an end of lock pin is placed to the first clamping groove and the second clamping groove, the unlatching that realization is locked.
As shown in Figure 5 and Figure 6, after again inserting the finishing key, because finishing key 100 is failed to being equipped with before the vane group effect of engineering pearl, the vane group that is equipped with the engineering pearl before can't making it is subjected to displacement, and this moment, engineering pearl 6 can't reset again under the effect of keeping out of vane group, causes the first clamping groove of the first blade of vane group bottom and the second blade and the second clamping groove position not corresponding with lock pin, can't open blade lock.
Said structure, by the engineering pearl, be located at stopper slot on the engineering pearl and limit spring and can realize that house-owner's key inserts after, the purpose that the finishing key can't be opened blade lock, therefore, with respect to prior art, security performance is improved, and implements restricted few.
The embedding of lock pin 5 and resetting structure can also be arranged to following structure: the first blade is provided with the first clamping groove near a side of lock pin, and the second blade is provided with the second clamping groove near a side of lock pin; The taper that one end of lock pin is and the first clamping groove, the second clamping groove match; Be provided with the hoodle containing hole on the inwall of lock housing, be provided with hoodle in the hoodle containing hole, be provided with spring between hoodle and lock housing.
In the utility model, the engineering pearl is a pearl, and it is sphere, and is as less demanding to the displacement accuracy of engineering pearl in realizing the purpose of this utility model, thereby can reduce the cost of making.Described sequin comprises pearl and blade.
For realizing the purpose of this utility model, described sequin can also be pearl, and namely the pearl lock construction with traditional is identical, and difference is to be provided with engineering pearl, stopper slot and limit spring.Certainly, can also be arranged to the blade of monolithic, be about to above-mentioned vane group and be modified into single blade, and realize resetting to single blade by spring is set between blade and lock core.
