CN2455873Y - Urgent unlocking device for electronic lock - Google Patents

Abstract

The utility model relates to an urgent unlocking device for electronic locks. A key is a barrel-shaped body 1 with a handle. The barrel-shaped body 1 is provided with a falcate groove hole 2. A lock core is an annular-hole groove column body 3. An annular-hole groove is fixed with a spacing ring 4 and a transverse shaft 5. The transverse shaft 5 is matched with the falcate groove hole 2 of the key, and is penetrated through the annular-hole groove column body 3. The annular-hole groove column body 3 is connected with a core shaft 6 which is arranged in the spacing ring 4. The back end of the core shaft 6 is fixed with a clamp ring 7. A spring 8 is arranged between the clamp ring 7 and the spacing ring 4. The exterior of the spacing ring 4 is sheathed with a swing rod 9. The swing rod 9 and the clamp ring 7 are provided with matched shift grooves. The utility model has the advantages of special purpose, difficult imitation, and difficult rust, and is suitable for outdoor use.

Description

The electronic lock emergent unlocking device

The utility model belongs to field of lockset, especially relates to the electronic lock emergent unlocking device.

Cross-connecting box is used electronic lock always, because the electronic lock circuit element inevitably certain fault can take place, this just can not guarantee that unlock circuit effectively unblanks, must a kind of mechanical reliable unlocking apparatus of employing.By the unlocking apparatus of investigation on the existing market, find that on the market the machinery key of unblanking is easy to copy, and for the electronic lock that uses out of doors, the keyhole easy-to-rust stops up, cause the later stage comparatively difficulty of unblanking, be not easy to management and safeguard.

The purpose of this utility model is to provide a kind of electronic lock emergent unlocking device, has specificity, is difficult for copying, and is difficult for corrosion, is fit to outdoor use.

The purpose of this utility model realizes by following technical proposals:

The electronic lock emergent unlocking device, its key has falcate slotted eye (2) for the cylindrical body (1) of band handle on the cylindrical body (1); Lock core is ring aperture groove cylinder (3), be fixed with spacing collar (4) and transverse axis (5) in the ring aperture groove, transverse axis (5) matches with on the key falcate slotted eye (2), and pass ring aperture groove cylinder (3), ring aperture groove cylinder (3) mandrel (6) interior with being contained in spacing collar (4) links to each other, stretch out outside the spacing collar (4) rear end of mandrel (6), the rearward end of mandrel (6) is fixed with snap ring (7), between snap ring (7) and the spacing collar (4) spring (8) is housed, spacing collar (4) is outer to be with a fork (9), and fork (9) has the allocating slot that matches with snap ring (7).

During use, cylindrical body (1) is on the key aimed at the ring aperture groove cylinder of locking (3), make falcate slotted eye (2) on the key be inserted in transverse axis (5), key, after making on the key falcate slotted eye (2) tangle transverse axis (5), outwards spur transverse axis (5), driving ring aperture groove cylinder (3) and mandrel (6) outwards moves, make snap ring (7) overcome the resistance of spring (8) and block fork (9), key is rotated fork (9) together again, backs down the banking stop in the electronic lock, thereby make lock pin under the effect of interlinked mechanism, withdraw from lockhole, reach the purpose of unblanking.

The utlity model has specificity, be difficult for imitatedly, adopt special material, can corrosion, solved the problem of outwork inclement condition very easily.

Be described in further detail the utility model below in conjunction with accompanying drawing.

Fig. 1 is the schematic diagram of the utility model embodiment.

Fig. 2 is the view of the A-A direction of Fig. 1.

Among Fig. 1, Fig. 2,1 is the simple shape body of key, and 2 is the falcate slotted eye, and 3 is the ring aperture groove cylinder, and 4 is spacing collar, and 5 is transverse axis, and 6 is mandrel, and 7 is snap ring, and 8 is spring, and 9 is fork, and 10 are the lock shell.

Fig. 1, electronic lock emergent unlocking device shown in Figure 2, its key for band cylindrical body 1, have falcate slotted eye 2 on the cylindrical body 1; Lock core is a ring aperture groove cylinder 3, be fixed with spacing collar 4 and transverse axis 5 in the ring aperture groove, transverse axis 5 matches with on the key falcate slotted eye 2, and pass ring aperture groove cylinder 3, and ring aperture groove cylinder 3 links to each other with mandrel 6 in being contained in spacing collar 4, and stretch out outside the spacing collar 4 rear end of mandrel 6, the rearward end of mandrel 6 is fixed with snap ring 7, between snap ring 7 and the spacing collar 4 spring 8 is housed, is with a fork 9 outside the spacing collar 4, fork 9 has the allocating slot that matches with snap ring 7.
