Abstract

The utility model provides a keyless spring ball lock. Compared with the previous spring lock, the utility model has the advantage that the keyless spring ball lock can be unlocked with no use of a key. The utility model adopts mechanical means. Over three pieces of digital code wheels are added on an ordinary spring lock. The inner ring of the digital code wheel is provided with a plurality of V-shaped grooves. According to the arrangement combination, each set of upper and lower balls of the lock can be controlled to contact on the interface between a lock core and a core sleeve. The lock is unlocked through rotating the lock core and driving a lock-opening mechanism.

Description

Keyless spring ball lock

The utility model is a kind of mechanical cylinder lock.

Lock is a protective device necessary in family, office, the industrial and mining enterprises, and cylinder lock is a kind of simple in structure, reliable operation wherein, the lock that purposes is the widest, but weak point is could open with key.People are often worried for wearing a big string key, and are anxious for losing key.

The purpose of this utility model is, makes a kind of cylinder lock that can open without key at the problems referred to above.

The utility model is a kind of improvement to cylinder lock, adopt every group of pellet shot from a slingshot of the direct control lock of method of machinery, promptly use several V-type teeth groove on 3 above digital wheel inner rings, press the position of every group of upper and lower pellet shot from a slingshot of permutation and combination control lock, every group of upper and lower pellet shot from a slingshot all contacted with the core retainer plate interface at lock core, can directly rotate or promote lock core, drive the mechanism that undoes the lock, lock is opened.

Fig. 1 is a front view of the present utility model, and Fig. 2 is the left view of Fig. 1, and Fig. 3 is the digital wheel part drawing.

Now further specify structure of the present utility model in conjunction with Fig. 1,2,3.

The utility model is made up of lock core (with handles) 1, core retainer plate 2, spring 3, time pellet shot from a slingshot 4, last pellet shot from a slingshot 5, digital wheel 6, pad 7, stop screw 8, back-up ring 9, nut 10, brace 11.Core retainer plate 2 usefulness nuts 10 are fastening with door.Illustrated among Fig. 1 pellet shot from a slingshot 5 on 4 groups, digital wheel 6 have been housed on the core retainer plate 2; Have a pad 7 to be separated by in the middle of each digital wheel 6, back-up ring 9 is used for fixing digital wheel and pad, and digital wheel 6 can rotate on core retainer plate, and lock core 1 is contained in the core retainer plate 2, and stop screw 8 can turn an angle lock core 1 in core retainer plate 2, but can not move axially.4 rows pellet shot from a slingshot 4 and spring 3 down are housed in the lock core 1, and upper and lower pellet shot from a slingshot, spring, digital wheel are corresponding one by one in a plane, and spring makes upper and lower pellet shot from a slingshot and digital wheel inner ring remain contact.Brace 11 connects lock core 1 with the mechanism that undoes the lock (can utilize the mechanism that undoes the lock of existing door lock or drawer-lock, not omit among the figure and draw), be the position that undoes the lock among the figure.

Fig. 3 is digital wheel 6 part drawings, the inner ring that there is shown at every digital wheel 6 has the V-type teeth groove that 12 degree of depth do not wait, wherein have only the V-type groove b that undoes the lock to have the effect of undoing the lock, have one and half V-type locating slot a to count starting point as digital wheel in addition, all the other V-type grooves are digital groove.When the degree of depth of groove of undoing the lock should guarantee that pellet shot from a slingshot falls into teeth groove, upper and lower pellet shot from a

slingshot

5,4 contacts at the interface of lock core 1 with core retainer plate 2, the degree of depth of all the other V-type grooves must be greater than or less than the degree of depth of (can not the equal) groove that undoes the lock, the degree of depth of all V-type grooves (comprising locating slot) should guarantee that pellet shot from a slingshot 5 is unlikely to eject core retainer plate 2, and following pellet shot from a slingshot 4 does not break away from lock core 1.

The open method of lock is as follows:

Rotate digital wheel 6, when last pellet shot from a slingshot 5 falls into locating slot a, digital wheel 6 is blocked, this moment backward rotation digital wheel 6 and begin counting, last pellet shot from a slingshot whenever falls into a V-type groove (can hear the sound, hand can be felt) be a number, when last pellet shot from a slingshot 5 falls into the groove b that undoes the lock, no longer rotate digital wheel 6.Rotate every group of digital wheel, make that pellet shot from a slingshot 5 all falls into the groove b that undoes the lock on every group, promptly every group of upper and lower pellet shot from a

slingshot

5,4 all contacts at the interface of lock core 1 with core retainer plate 2, and this moment is the rotational lock core handle directly, drive the mechanism that undoes the lock by brace 11, lock is opened, as long as there is a digital wheel 6 to turn over the position that undoes the lock, last pellet shot from a slingshot 5 promptly snaps in lock core 1, or pellet shot from a slingshot 4 snaps in core retainer plate 2 down, lock core promptly is stuck, and can not rotate, and lock can't be opened.

Fig. 4 is the another kind of form of Fig. 1, and basic structure is identical with Fig. 1, has just removed the handle on Fig. 1 lock core, has a helicla flute 15 on lock core 1, pinning 12, and there is stage clip 13 the lock core end.As previously mentioned,, promote lock core 1,,, drive the mechanism that undoes the lock, lock is opened by brace 11 because the effect of helicla flute 15 makes lock core simultaneously move one side and rotates when all digital wheels all are in when undoing the lock the position.

Fig. 5,6 is used for the structure chart of padlock for the digital wheel controlling organization.

The advantage of this lock is, directly control the unlatching of every group of pellet and the lock of lock with mechanical means (digital wheel), saved key, simple in structure, reliable operation, good looking appearance, good confidentiality, if have the digital groove of 11 V-types in the every digital wheel, a lock then has 14641 kinds of aligning methods with 4 by permutation and combination, is not easy to decode, and digital groove is in inside, the outside be can't see, in case digital being penetrated, as long as come loose nut 10, take off core retainer plate, the position that exchanges several digital wheels 6 is convertible number.

This locking fabrication technique is simple, can utilize the mechanism that undoes the lock of existing door lock or drawer-lock, changes pellet and partly gets final product.
