Description

Ball puzzle lock

The utility model relates to a kind of improved coded lock, is used for the antitheft of door, window and motorcycle etc.

Existing coded lock has varied, provides very big help to people aspect antitheft.But,, influenced it and applied owing to exist such-and-such problem.Contrast by analysis, aspect such as major defect shows complex structure, makes difficulty, uses operation inconvenience, and theftproof performance is not good enough, and major part all is furnished with private key, and key also needs meticulous keeping, increases trouble to the user.

It is a kind of simple in structure that the purpose of this utility model is to provide, and makes easily, use easy to operate, the Ball puzzle lock that theftproof performance is good.

Ball puzzle lock described in the utility model, lock body and locking bar are arranged, latch arm hole is arranged on the lock body, the one tubulose password seat corresponding with latch arm hole arranged on its lock body, be with the password circle on the password seat, have on the inwall of password circle one with password seat ball hole in the corresponding circular arc pit of ball, password seat ball hole base diameter is less than ball diameter, locking bar is provided with the circumferential arc groove corresponding with the password circle.

Locking bar passes that latch arm hole is inserted in the locking bar jack of password seat on the lock body, the rotational password circle is avoided the pit on the password circle, the ball in the password seat ball hole by squeeze seal in ball hole, and protruding reveal to the locking bar jack of password seat with locking bar on circumferential arc groove fasten, lockset is pinned; On the contrary, the rotational password circle, when making the ball in the corresponding password seat of the pit ball hole on the password circle, ball can be under the extraction effect of locking bar, in the pit of rollback to the password circle, removes the fastening of ball and locking bar groove, thereby lockset is opened.Simple in structure, make easily, need not key, use easy to operately, theftproof performance is good, and the number of increase password circle can increase antitheft grade.Ordinary circumstance, password circle number is advisable with 2-6, and password circle number is too many, and the password figure place increases, and operates loaded down with trivial detailsly, also easily password is forgotten about.

The password seat is fixed on the lock body by fixing pin, and the dowel fixes place of password seat is designed to a circumferential slot, has guaranteed that locking bar and password seat can both at random rotate, and brings convenience for using operation.

Below in conjunction with the embodiment accompanying drawing the utility model is further described.

Fig. 1, the structural representation of the utility model one embodiment under lock-out state.

Fig. 2, password holder structure schematic diagram.

Fig. 3, password coil structures schematic diagram.

Fig. 4, Structure of lock rod schematic diagram.

Among the figure: 1 lock body, 2 locking bars, 3 fixing pins, 4 balls, 5 password circles, 6 password seats, 7 pin circumferential slots, 8 ball holes, 9 locking bar jacks, 10 circular arc pits, 11 arc grooves.

As shown in the figure, Ball puzzle lock described in the utility model, lock body 1 and locking bar 2 are arranged, latch arm hole is arranged on the lock body, the one tubulose password seat 6 corresponding with latch arm hole arranged on the lock body 1, be with three password circles 5 on the password seat 6, have on the inwall of password circle 5 one with password seat ball hole 8 in the corresponding circular arc pit 10 of ball, three ball holes on the password seat are in upwards dislocation layout of password seat week, the base diameter of password seat ball hole 8 is less than ball diameter, and locking bar 2 is provided with the circumferential arc groove 11 corresponding with the password circle.

Rotate each password circle, make the pit correspondence ball in the password seat ball hole separately on the password circle, ball can be under the extraction effect of locking bar, in the pit of rollback to the password circle, remove the fastening of ball and locking bar groove, this moment, lockset was in open mode, locking bar passed latch arm hole is inserted in the locking bar jack of password seat on the lock body, the rotational password circle is random number respectively, make ball avoid pit on the password circle, then ball by squeeze seal in ball hole, and protruding reveal to the locking bar jack of password seat with locking bar on circumferential arc groove fasten, lockset is pinned; On the contrary, the rotational password circle when making each ball in the corresponding password seat ball hole of pit difference on the password circle, is removed the fastening of all balls and locking bar groove, lockset could be opened.If setting code is divulged a secret, then can unclamp fixing pin 3, transposing password circle resets password, and safe and reliable, theftproof performance is strong.Dowel fixes circumferential slot on the password seat makes password seat axial restraint, and locking bar and password seat can both at random rotate, and brings convenience for using operation.

From this, the utility model is simple in structure, and is scientific and reasonable, makes easily, need not key, uses easy to operately, and roll structure forms the circular arc contact, and action is excessively slick and sly, avoids feel to decode, and theftproof performance is good, and is easy to utilize.
