Description

A kind of push-button puzzle lock

The utility model relates to lockset, and especially a kind of push-button puzzle lock mainly is applicable to lock bicycle, motorcycle, tricycle, door and cabinet.

Existing coded lock mostly is the digital coded lock of roller type, has removed the worry that the user carried, lost key, but its mechanism is complicated, not variable sign indicating number, and easy break-down can't use under no light.

In view of there are the problems referred to above in prior art, the purpose of this utility model provides a kind of push-button puzzle lock, and it is not only simple in structure, become sign indicating number easily, failsafe has been removed the worry that the user carried, lost key, and under no light, can unblank to lock with feel, practicality is good.

The utility model push-button puzzle lock, its ingredient comprise that locking bar that a lock body, that ten same cryptographic keies and location amortisseur bar, anti-sawing blade and latch arm hole be housed has a lock pin through hole that ten hole center to center distance equal above-mentioned key lock pin center to center distance and two ends are connected the lock cable of lock body and locking bar respectively.

Have ten onesize cryptographic keies that vertical through hole is installed in this lock body, this hole and cryptographic key are for being slidingly matched.

Cryptographic key is in this lock body

Shape is made of key body, lock pin and locking bar space.

Ten cryptographic key lock pin center to center distance equal ten lock pin through hole center to center distance on the above-mentioned locking bar in this lock body.Lock pin and its hole are for being slidingly matched.

In this lock body inside, lean on the position at the cryptographic key back side that horizontal amortisseur bar construction opening hole is arranged, the amortisseur bar at the local back side of squeeze pin key is arranged in the hole, can not free displacement to guarantee cryptographic key.

Respectively have horizontal anti-sawing blade construction opening hole at the inner upper and lower sides of this lock body position, but Kong Zhongyou free rolling anti-sawing blade, to strengthen anti-saw effect.

Ten cryptographic keies in this lock body are placed on the enable possition, behind the insertion locking bar, change 1-10 key upper-lower position arbitrarily, lock can be locked.Change password bond number is many more, and confidentiality is good more, when unblanking, the cryptographic key that has changed upper-lower position is reset to the enable possition, can extract locking bar out, and locked object is in non-lock state.When this lock does not use, locking bar is inserted lockhole for well, in case key comes off.

The utility model push-button puzzle lock has aforesaid advantage owing to adopted above-mentioned design scheme: simple in structure, durable, easy break-down not, become sign indicating number easily, and under the situation of not having light, can use, also provide a kind of lockset for the blind person.

Below with reference to accompanying drawings the utility model structure is described further.

Fig. 1 is the utility model push-button puzzle lock structural scheme of mechanism and specification digest accompanying drawing.

Fig. 2 is an A-A cross-sectional view among Fig. 1.

Fig. 3 is lock body 10 a mold pressings symmetry part structural representation among Fig. 1 and Fig. 2.

Fig. 4 is locking bar 16 structural representations among Fig. 1, Fig. 2.

Fig. 5 is cryptographic key 12 structures and a mounted in pairs position view thereof among Fig. 1, Fig. 2.

With reference to Fig. 1 and Fig. 2, the utility model push-button puzzle lock ingredient comprises that locking bar 16 that a lock body that is made of two moldings (Fig. 3) that ten same cryptographic keies 12 and location amortisseur bar 18, anti-sawing blade 15 and latch arm hole 21 arranged 10, one have a lock pin through hole 17 that ten hole center to center distance equal above-mentioned cryptographic key lock pin 23 (Fig. 5) center to center distance and two ends are connected the lock cable 22 of above-mentioned lock body coupling part 13 (Fig. 3) and locking bar 16 rear ends respectively as can be known.

The installation vertical through hole 0-9 of the coded lock 12 that the hole center to center distance that has ten onesize branch two rows to arrange on the lock body 10 equates.The size in this hole is slidingly matched to push wherein with cryptographic key 12 and is as the criterion.

Cryptographic key 12 is Shape constitutes (Fig. 5) by key body, lock pin 23, locking bar 16 space S.In order to make it durable, wherein be pressed with metal reinforcing (Fig. 5 does not represent).

Ten cryptographic keies 12 in the lock body 10, after locking bar 16 inserted latch arm hole 21, the user can press corresponding cryptographic key 12 according to required password combination number just can obtain one group of password combination locking object.

Because any one of ten cryptographic keies 12 all can be installed square vertical through hole 0-9 from lock body 10 positive and negative cryptographic keies and pack into and put in place, its lock pin 23 can enter all that lock pin through hole 17 is lock-out state on locking bar 16 positive and negative, so the password combination number of the utility model coded lock is 2 ¹⁰

At lock body 10 inner positions near cryptographic key 12 back sides, there are horizontal amortisseur bar 18 construction opening holes 19 at the promptly local position that sees through through hole 0-9 inwall, amortisseur bar 18 is arranged in this hole, so, amortisseur bar 18 in the hole is squeeze pin key 12 back sides effectively, making it can not free displacement, is in correct locking and unlock state with security code key 12.

Latch arm hole 21 is the transverse holes of vertically through cryptographic key 12 square vertical through hole 0-9 mid portion being installed.When ten cryptographic keies 12 all are in off working state, promptly during reset mode, the B face of each cryptographic key 12 flushes in latch arm hole 21 bottom surfaces, forms unobstructed latch arm hole, and locking bar 16 can insert and put in place.

12 minutes two rows of button cryptographic key in the lock body 10 symmetric arrays.It installs among the square vertical through hole 0-9 its A in the face of the A face is packed in pairs, and latch arm hole 21 width are the relative mounting distance of paired cryptographic key 12A face, and it highly is the height h of cryptographic key 12B face to lock pin 23 front ends.Its length is longer than above-mentioned 10 through hole 0-9 length slightly.

Locking bar 16 thickness, height and length put in place with the insertion latch arm hole 21 that is slidingly matched and are as the criterion.After locking bar 16 insertion latch arm hole 21 put in place, ten lock pin through hole 17 centers overlap with lock pin 23 centers of cryptographic key 12 on it, and at this moment, lock pin 23 just can insert lockpin hole 17, as shown in Figure 1 and Figure 2, the lock pin 23 of the 8th, the 9th cryptographic key 12 inserts on the locking bars 16 in the 8th, the 9th the lock pin through hole 17.This shows that lock pin 23 center to center distance that cryptographic key 12 is installed the cryptographic key 12 among the square vertical through hole 0-9 in the lock body 10 equal the center to center distance of the lock pin through hole 17 above the locking bar 16.

At lock body 10 inner upper and lower sides anti-sawing blade 15 construction opening holes 14 are arranged respectively, anti-sawing blade 15 is housed in the hole.

In order to make safety in the utility model use, reliable, anti-saw, pick-proof, the stiffener 11 that has ten cryptographic keies installation square through holes and five rivet holes 20 is arranged in the last attaching of lock body 10 positive and negatives.

Button cryptographic key 12 lengths are

25mm (length), its lock pin 23 sizes (mm) are 3 * 2 * 1.5, the locking bar space S is 4 * 4 * 4 (mm).

The utility model lock body 10 is that the riveted joint of two mold pressings symmetry part constitutes for one.

Lock body 10 is pasted with protective jacket with lock cable 22, not expression on the figure.

The utility model lock materials and the equal specific (special) requirements of technology are suitable for producing in batches.
