Description

The multi-functional cabinet lock

Technical field

The utility model relates to one group of multi-functional cabinet lock, belongs to the lock field.

Technical background

Present lock of the prior art is mostly for opening different locks with different keys, can not drive other lock again, and can not dismantle trivial core voluntarily. this shortcoming of opening different locks with different keys is: for the people that often will drive many locks, must be with at any time many keys on one's body, this is very inconvenient; Stolen or the key loss when lockset is in addition opened cabinet and need be changed whole lockset, and so not only replacing is more time-consuming, bothersome, and also uneconomical.

Summary of the invention

The purpose of this utility model is to design a kind of one group of multi-functional cabinet lock lock being made of n, every lock in this group can both be joined A, B, three kinds of keys of C, A, B, three kinds of keys of C have routine function down: 1, A kind key can only be driven corresponding in a group lock, 2, B kind key can be driven any lock in the group, and 3, C kind key can give dismounting like a cork the lock core of any lock in the group or install.Very convenient for the people of many locks of needs pipe like this, needn't be with numerous keys, even key is stolen or loss, it is also very convenient to change lock core.

The purpose of this utility model is achieved in that the special lock core that placement is complementary in one group of lock housing endoporus, and lock core is provided with the tongue piece of under key effect regracting or ejection; This group lock core is when inserting A, B, three kinds of keys of C, but withdrawal of the tongue piece on the control lock core or ejection, make that the tongue piece on each lock core reaches in the group: when 1, A kind key inserts lock core, can only the control group in a corresponding lock the withdrawal of lock core upper tongue or eject, do not hold tongue piece uncontrolled in the lock.When 2, B kind key inserted lock core, the withdrawal of lock core upper tongue or the ejection of all locks did not hold tongue piece uncontrolled in the energy control group in the lock.When 3, C kind key inserted lock core, tongue piece withdrawal or ejection in the energy control group on the lock core of all locks comprised the not end tongue piece in the lock.So just reach A kind key and can only drive lock in the group, B kind key can be driven whole group lock in group, and C kind key can be given the purpose of dismounting or installation the lock core of putting in order the group lock in group.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail:

By Fig. 1-3 as seen, this multifunctional lock is made of lock housing 10 and the lock core 20 and the keys 30 that are installed in the lock housing 10, and the wall of lock housing 10 is provided with axial notch 11 and radial groove 12, and the endoporus 13 and the lock core 20 of lock housing 10 match; Lock core 20 is provided with the groove 23 of a plurality of placement tongue pieces 40, and tongue piece 40 is installed in the groove 23 of the lock core 20 of being furnished with the spring (not shown), does not wherein hold tongue piece 401 position alignment radial grooves 12, does not hold tongue piece 401 ascending, descendings among groove 12; The front end face 22 of lock core 20 is provided with the keyhole 21 that inserts key 30, and key 30 inserts in the lock core 20, and the tooth portion 31 of key 30 matches with bottom, the hole of tongue piece 40, and takes this to drive strike plate 40 ascending, descending in groove 24.

As seen from Figure 4, endoporus 41 shapes of tongue piece 40 bottom can be divided into 412 2 parts in the end, a left side 411 and the right end; For the end 411, a left side, the right end 412, can a kind of key bit of corresponding separately pairing portion 31, the endoporus 41 of tongue piece 40 just can match the tooth portion 31 of two kinds of keys like this.When making lock core 20 with this tongue piece 40, as long as it is unified the direction at the left end 411 of all tongue pieces 40 in the lock core and the right end 412, the left and right right unanimity of installing of returning is returned on a left side,, just there are left and right two tooth roads at the end in its lock core keyhole 21, can match two kinds of different key 30A (see figure 5)s and 30B (see figure 6) respectively; There is a difference in the tooth portion 31 of these two kinds of keys on the back of tooth 32, a first from left is right on the back of tooth 32 of key 30 is provided with.Utilize these characteristics, at one group of N tongue piece 40 of packing on the lock core 20 of lock, make the left end 411 and the right end 412 in the tongue piece hole 41 of these locks in keyhole 21, form left and right two tooth roads, one of the die cavity in these two tooth roads is made the non-unified end, the 31A of tooth portion of pairing A kind key, another makes the unified end, the 31B of tooth portion of pairing B kind key, and this group is locked in and just reaches following purpose in the use like this.

When A kind key inserts lock core 20 fully, when at the bottom of tongue piece 40 holes of A kind key bit portion 31 and lock core 20 inside 411 or 412 when not being harmonious, can not control the tongue piece 40 withdrawal (see figure 7)s of lock core 20, lock core 20 can not rotate, and lock is not opened.When A kind key inserts lock core fully, when 40 ends of tongue piece hole of A kind key bit portion 31 and lock core inside, match, the tongue piece 40 withdrawal (see figure 8)s on the lock core 20, at this moment rotational lock core 20 just can be opened lock.

When B kind key inserts lock core 20 fully, because one of the left end 411 at the bottom of tongue piece 40 holes that N only locks in B kind key bit portion 31 and the group or the right end 412 pairing, tongue piece 40 in the group on all lock cores 20 (do not contain and the do not hold tongue piece) (see figure 9) of can both withdrawing, rotational lock core 20 just can be opened each lock in the group, and B kind key can be driven all locks in group like this.

C kind Key structure is to increase the tooth portion 30C (see figure 10) of a retaining with pairing at the bottom of not holding tongue piece 411 holes in the end of B kind key, when C kind key inserts lock core 20 fully, can or eject 40 withdrawals of the tongue piece on all lock cores 20 in the group, comprise the not end tongue piece (seeing Figure 11) in the lock.All tongue piece 40 withdrawals on lock core 20, lock housing 10 and the lock core 20 that is installed in the lock housing 10 just can installation or removal.
