Abstract
The utility model provides a key-cipher double-safety anti-theft padlock. The utility model is improved and additionally provided with a cipher safety device on the basis of a common padlock which is composed of a lock stem, a lock core, a lock tongue, a spring, a lock body and a key. When the metal pin on a cipher wheel is arranged in the cross slot of the lock stem, the padlock still can not be opened even if the user is provided with the key. The utility model is suitable for being used in the family, the shop and the storehouse.
Description
The utility model relates to a kind of improved padlock.
Existing padlock mainly contains lock stalk, lock core, lock body, dead bolt, spring and key to be formed, and it mainly is to open and insure by the spring of dead bolt.Its shortcoming is to surpass under the stressing conditions of latch bolt spring pressure, and it is opened with regard to taking off tongue easily, so safety factor is not high.
At above-mentioned shortcoming, the utility model proposes a kind of theft proof padlock with key and password double insurance device.
The utility model is finished in the following way: on the lock stalk of the location of existing padlock, increase several cipher wheel; One fixing metallic pin is arranged on the cipher wheel, on the lock stalk, open several (horizontal stripes) with the parallel translot of cipher wheel with one with the vertical straight trough of translot.When cipher wheel was pulled out the password that sets, the metallic pin on each cipher wheel just entered in the straight trough of lock stalk, and this moment just can be by key operated.And when position that cipher wheel is not being set.(as long as the position that wherein has a cipher wheel not setting) is because the metallic pin on the cipher wheel has blocked the pin stalk, even therefore have key can not open padlock.In addition, when theft proof padlock is being subjected to surpassing under the latch bolt spring pressure, the metallic pin on (if position that this moment, cipher wheel did not set) cipher wheel can bear impressed pressure and move after can not making latch bolt spring and open padlock; When impressed pressure exceeded the pressure that the metallic pin on the cipher wheel can bear, metallic pin can be embedded in the translot of lock stalk, and padlock can not opened by force, has so just reached the increase safety factor, antitheft purpose.
As a conversion example of the present utility model, as required, lock stalk translot can be one to five, and the cipher wheel corresponding with it also can be one to five.
The utility model is easy to use, and safety factor increases greatly, is particularly suitable for family, shop, warehouse and easy stolen place and uses.
Embodiment: (is example with three cipher wheel)
Fig. 1 is the longitudinal sectional drawing of key cipher dual-safety anti-theft padlock;
Fig. 2 is the sectional drawing of cipher wheel.
Wherein 1: key; 2: lock body; 3: the lock core spring; 4: lock core marble; 5: lock core; 6: dead bolt; 7,8,9: cipher wheel; 10: the lock stalk; 11: latch bolt spring; 12: straight trough; 13,15,17: translot; 14,16,18: metallic pin; 19: the fixed limit latch; 20: lock stalk spring; 21: the Fixed latches stopper slot.
Count under the situation at the password of setting, the metallic pin 14,16,18 on the cipher wheel 7,8,9 just enters in the straight trough 12, makes it to be in the same line.Metallic pin 14,16,18 on the cipher wheel 7,8,9 can be done the rotation arbitrarily of 360 degree in the translot 13,15,17 of lock stalk 10.Open by key 1, make latch bolt spring 11 indentation backward, thereupon 6 while of dead bolt setback; At this moment, lock stalk spring 20 be not subjected under any pressure, and with the unlatching plane that lock stalk 10 ejects lock body 2, the fixed limit latch 19 that at this moment is set in the straight trough 12 just in time springs into Fixed latches stopper slot (21), and can carry out the rotation of 360 degree, just can open this dual-safety anti-theft lock.
If metallic pin 14,16,18 is (as long as any one in the metallic pin 14,16,18 be not in straight trough 12) not in straight trough 12, even there is key 1 to rotarily open, latch bolt spring 11 indentation backward, dead bolt 6 is the while setback thereupon, because the safety effect of metallic pin 14,16,18, can not make lock stalk spring 20 will lock stalk 10 and eject lock body 2, so just reach the purpose of Cipher safety.
