The specific embodiment
The structure of lock gall and corresponding courage cover should be noted in reference to the accompanying drawings take the peach offered as a birthday present mortice lock as embodiment describes in detail replaceable core of the present invention, and design of the present invention also goes for the lock of other type.
Fig. 3 is lock gall and corresponding courage cover and the decomposition diagram that changes accordingly the courage spoon in the replaceable core of the present invention.Lock gall 2 is fixedly mounted in the courage cover 9, and they are called lock core together with relevant annex.For the peach offered as a birthday present mortice lock, above-mentioned lock gall 2 and courage cover 9 are basically cylindrical.Described lock gall 2 inserts in the hole of courage cover 9, is connected with courage cover 9.The top edge of meson 1 is projected into outside the external surface of courage cover 9, so that described lock gall and courage cover are fixed on lock body or the installation site such as objects such as doors.Must be to cooperatively interact when lock gall and courage are enclosed within work, lock gall only can rotate in the courage trepanning, and the combination of lock gall and courage cover is called " lock core ", when changing lock gall, is in fact that lock gall and courage cover are together taken off, and therefore is called " replaceable core "; But be exclusively used in the key of changing lock core and still be called traditionally " changing the courage spoon ".
According to the present invention, described meson can be positioned at projection position or dial upper/lower positions, on projection position, the top edge of described meson is projected into outside the external surface of described courage cover, described lock gall and courage cover can be fixed on its installation site, and on dialling upper/lower positions the time, the top edge of described meson flushes with the external surface of described courage cover or is lower, can not be used for fixing described courage to overlap and lock gall; Described lock gall and courage put and are respectively equipped with a plurality of locks hole of bead that comprises each lock pearl such as Guan Zhu, leader pearl and lower pearl for installation, have in the described lock gall for the keyhole that inserts key.The size in the pipe hole of bead in the described courage cover is greater than the diameter of described Guan Zhu, so that when insertion is changed the courage spoon and described Guan Zhu is headed in the described pipe hole of bead, the rotation of changing the courage spoon can drive described lock gall and rotate an angle in the courage cover, in order to described meson is moved to group upper/lower positions from projection position; And, no matter be that described meson is all covered by the lock gall parts around the keyhole, can not see from described keyhole at projection position or at group upper/lower positions.
As shown in Figure 4, described meson 1 is tool annular shape jaggy, is called the open-type meson, and comprises that is colluded a shape thing A, and after being installed to meson in the lock gall, described breach and described position of colluding the shape thing are lower than described keyhole.
A back-moving spring 5 can also be installed in the lock gall 2, it can lock gall and courage cover be installed to its installation site such as objects such as doors on after make described meson be returned to position outside the external surface that its top edge is projected into described courage cover, thereby described lock gall and courage cover are fixed on the described installation site.For example, it can be used for making the position that is returned to projection by the meson 1 under dialling.Comprise respectively a plurality of locks hole of bead in lock gall 2 and the courage cover 9, be used for inserting various lock pearls, comprising: pipe pearl 6, leader pearl 7 and lower pearl 8 etc., the diverse location of these lock pearls and the combination of length can be for concrete shape and the structures of spoon tooth of unblanking of setting lock gall.Also comprise two cover plates 10 on the courage cover 9, be used for above-mentioned lock pearl is enclosed in the courage cover.Other parts in the lock such as latch hook or toggle mechanism etc. do not show, because the present invention does not change these parts.Also comprise in the lock gall 2 for the keyhole that inserts key.
Fig. 4 is the stereogram of meson 1 of the present invention.Fig. 4 is compared and can find with Fig. 1 b, and the meson of prior art is the annular of sealing, and meson of the present invention 1 is annular jaggy, comprises that in its indentation, there is colluded a shape thing A.In addition, on being installed to lock gall 2 after, meson of the prior art be by the long spoon point that changes the courage spoon directly to pressing down, thereby it is concordant with the external surface of courage cover that meson is moved to, to take out lock gall and courage cover; And the perforate in the meson of the present invention is larger, after on being installed to lock gall 2, can do not changed the courage spoon directly depresses, but need to change courage spoon 3 and the certain angle of lock gall 2 rotations, for example 15-50 °, especially 25 °, just can above-mentionedly collude shape thing A and with under 1 group in the meson by what stir meson, the top edge of meson is moved to concordant with the external surface of courage cover/lock gall, thereby can take out lock gall and courage cover.Above-mentioned rotational angle can only be used for changing lock gall 2, and lock can not be opened.
After taking out lock gall and courage cover, new lock gall 2 and courage cover 9 can be installed, then will change courage spoon 3 and turn to the normal position, above-mentioned back-moving spring 5 in the new lock gall can automatically return to meson the position that exceeds lock gall surface or courage cover surface, and new courage cover 9 is fixed in the installation site of waiting on the object.
Fig. 5 is for the comparison diagram that changes courage spoon and standard spoon according to lock gall of the present invention.The described courage spoon that changes comprises handle portion, spoon tooth part and spoon nose part.Spoon tooth in the described spoon tooth part of changing the courage spoon lacks than spoon tooth of the standard spoon that is used for described lock gall is unblanked.And, the depth as shallow of corresponding spoon tooth in the described depth ratio standard spoon that changes corresponding with the pipe pearl of lock gall spoon tooth in the courage spoon.As shown in Figure 5, change courage spoon 3 longer than standard spoon 4; Change the spoon tooth that only has a part on the courage spoon 3, for example only have a row, and on the standard spoon by two row spoon teeth, and it is different from the standard spoon to change the degree of depth of spoon tooth on the courage spoon.In addition, change courage spoon 3 the spoon nose part also can from standard spoon 4 the spoon nose part different.
According to the present invention, after will changing courage spoon 3 and inserting in the lock galls 2, change the position that the courage spoon can exceed pipe pearl 6 jack-up to the lock gall surface, make the pipe pearl 6 can only be movable in courage overlaps 2 the pipe hole of bead, as shown in Figure 9, hold and the lock gall flush on the lower pearl in other hole of bead.The size in the described pipe hole of bead can be the 2 times or more large of described pipe pearl diameter.For example, the described pipe hole of bead can be the strip hole, and other hole of bead is columniform, therefore, changes courage spoon 3 and can only rotate less angle in lock gall 2, for example can only rotate counterclockwise approximately 15-50 °, especially 25 °, can not clockwise rotate, defining lock gall by another mechanism in the lock when being locked in lock-out state because of this again can not rotate counterclockwise, therefore when blocking, do not rotate lock gall with changing the courage spoon, just can not change lock core yet; Namely change lock core and must be under the state when lock is opened and carry out.Cut short or be revised as the same with the standard spoon long even will change the spoon nose part of courage spoon 3, can not unblank.
From above-mentioned lock gall of the present invention 2 and the structure of changing courage spoon 3 as can be known, if the strip object inserts in the lock gall arbitrarily, the lower pearl 8 that is used for lock gall 2 is different in size, then this strip object can cause the height of described lower pearl 8 in lock gall 2 uneven, this strip object lock gall rotated, so can not be opened lock.
Fig. 6-Fig. 9 shows that will change courage spoon 3 inserts after the lock gall 2, changes the interactional situation of courage spoon 3 and meson 1, and wherein lock gall 2 is arranged in courage cover 9, and courage cover 9 is partly cut to show open its internal construction.
Fig. 6 has shown that will change courage spoon 3 is inserted into situation in the lock gall, and wherein lock gall is in courage cover 9, and the spoon point that changes courage spoon 9 extends to the position of meson 1 always, contacts with the A of the shape section of colluding of meson 1.Fig. 6 is compared with Fig. 2 and can find out, the meson of meson of the present invention and prior art is except shape is different, the courage spoon that changes of the present invention flatly inserts lock gall and vertical with the vertical edge of meson, and the courage spoon that changes of prior art inserts lock gall and parallel with the vertical edge of meson vertically; In addition, the meson of prior art is case type, the position of its perforate faces keyhole, when the top edge of meson is projected into outside the external surface of lock gall, the lower limb of the perforate of this meson can see from lockhole, and this mode has determined that it necessarily can be depressed and can change courage by strip object arbitrarily.Therefore and meson of the present invention is the both sides that the breach breach type and described is positioned at keyhole, can't see any part of meson from keyhole, thereby the strip object can not insert keyhole and touch meson of the present invention it is depressed arbitrarily.
As shown in Figure 7, the spoon point that needs to change the courage spoon rotates the position of an angle under just meson can being pushed, to change courage.Fig. 8 be with Fig. 7 in the enlarged drawing of meson place part, a spoon nose part that wherein changes courage spoon 3 extends to colluding on the shape thing of meson 1, can for example rotate 25 ° and described meson is pushed upper/lower positions by changing the courage spoon.
In addition, can find out from top description, of the present invention changing only has row's spoon tooth on the courage spoon, can not unblank so change the courage spoon, and can only change courage.Shown among Fig. 9 change the courage spoon in inserting lock gall after, change the spoon tooth of courage spoon and will manage because the degree of depth is more shallow during pearl jack-up overlaps the pipe hole of bead 6 in 9 to courage, make Guan Zhu exceed a little the surface of lock gall.Because the pipe hole of bead in the courage cover 9 is the strip hole, the pipe pearl can be in the pipe hole of bead mobile certain scope, for example with the center of lock gall section as the center of circle, the angle that can rotate lock gall is in about 15 °-50 ° scope, preferably can move 25 °, thereby can change courage.
According to the present invention, need to use have a correct spoon tooth change the courage spoon, and need to rotate certain angle and just meson can be dialled down, thereby can change courage.Therefore, can utilize " needing to rotate certain angle " this operation to verify the correctness of spoon tooth, if inaccurate spoon tooth, lock gall can not rotate, and also just can not dial lower meson and change courage.And the lock of previously described prior art does not need to verify whether the spoon tooth that changes the courage spoon is correct, and it changes the courage spoon and basically can realize with any strip object.
And for lock gall of the present invention, because the surface configuration of strip object is hardly may be just consistent with spoon thread form shape that changes the courage spoon arbitrarily, so the strip object can not rotate lock gall after in the insertion lock gall arbitrarily, also just can not change courage.Therefore, use the lockset of lock gall of the present invention that higher safety is arranged.
Figure 10 a is installed in schematic diagram when upper with lock gall (with the courage cover), and Figure 10 b is the enlarged drawing of lock mounting portion among Figure 10 a.Shown in Figure 10 a and 10b, after being installed on the door, described meson 1 is projected on the external surface of described courage cover 9, and described courage cover 9 and lock gall 2 wherein are fixed on the door.
If will insert in the lock gall with the corresponding standard spoon of lock gall or common spoon, as shown in Figure 5, because the standard spoon is shorter, its spoon tip part can not extend to the position of described meson, this standard spoon can drive described lock gall and rotate to unblank or lock arbitrarily, and can not make any movement of meson production.
According to the present invention only have a row spoon tooth on the courage spoon owing to changing, so one change the courage spoon can be corresponding from a plurality of different standard spoon and lock galls, that is to say, one is changed the courage spoon and can be used for changing a plurality of different lock galls.
Although above-described embodiment is introduced the solution of the present invention with the lock gall of peach offered as a birthday present mortice lock, also can use lock gall of the present invention in the lockset of other type and change the courage spoon.
In sum, lock gall of the present invention and change accordingly the courage spoon and both can make and change the easy and simple to handle of courage can strengthen again the safety of lock gall, has significant progress with respect to lock gall and the lockset of prior art.
Abovely introduced principle of the present invention and structure with preferred embodiment, it is descriptive that foregoing is regarded as merely, and nonrestrictive.The instruction of those skilled in the art in can be to specifications to the present invention carry out various improvement and/revise, these improvement and/or revise all should be included in the scope of claims of the present invention.
