Abstract

The utility model discloses a bicycle code lock which relates to a lock. The code lock overcomes all defects of a traditional lock and is a perfect combination of digit and machinery. The code lock mainly consists of a lock body, a number-matching wheel, a core-pulling wheel, a lock core, a blot and a spring. The most important thing is that the number-matching wheel and the core pulling are same in external features but different in internal structure. The lock core is provided with the bolt and the spring inside. The novel and unique structure of the code lock makes the unlocking and locking convenient and quick and also doubles the confidentiality. If the unlocking way does not be mastered, the lock can not be unlocked even the code is known by others. The purposes of the lock can be widened by matching different lock frames such as steel wires and chains. The code lock is especially applicable to the used outside; and the code lock is water-proof and corrosion-proof and cannot be damaged naturally or artificially because of losing key, thereby definitely prolonging the service life of the code lock.

Description

The bicycle coded lock

Technical field

What this utility model related to is a kind of lockset.

Background technology

Known various lockset all is with key operated mode mostly.Especially in the open the lockset of Shi Yonging all has a fatal shortcoming, fears rainwater.Because of part is tiny, compact conformation, very easily corrosion, thus cause nature to damage.In a single day key is lost, and causes artificial destruction sometimes again, therefore causes the application life of lockset extremely low.Traditional check mark formula lockset in disorderly dialling fast, promptly has to make lock bridge eject the possibility of (opening) automatically sometimes, and security performance is too poor.And when locking, must check the number earlier, lock bridge could be inserted then, very trouble.

Summary of the invention

This utility model has overcome the various shortcomings of conventional lock, and a kind of rainwater of not being afraid of is provided, and is not afraid of and loses key, the conveniently combination type lockset of high security of locking and unblank all.Be particularly suitable for being used on the bicycle.Part drawing is seen Fig. 1, Fig. 2, and Fig. 3, schematic diagram is seen Fig. 4.This lockset is an example with four rolling (check the number wheel and group core wheel are referred to as roller), and using method is very simple, needs only wherein three (oneself is known) check mark wheel aligning numbers when unblanking, and rotates one again and sets aside the core wheel, locks and just opens.Need only when locking lock bridge is inserted in the hole.

Lockset principle and structure: three check the number wheel and one group of core wheels are arranged in four rolling, can't differentiate, when rotating, really can feel out though the four rolling profile is the same.Because of rotatable 360 degree of the wheel of checking the number, and the side of group core wheel has the inclined-plane 14 of protrusion can not rotate 360 degree.For the rotation radian that makes four rolling is the same, feel is the same.So side with circle in three wheels of checking the number.Increased a protruding tongue 13, protruding tongue 13 can be stuck on the shoulder of lock core 15 when rotating a nearly circle place, and not only external form is the same for four rolling like this, has rotated radian and feel too, and then has played secret effect.

When unblanking, though need only participate in check mark by three wheels of checking the number, the probability that stranger's test is unblanked still is four numbers, and promptly 10 4 powers are 10000 times.Suppose that the stranger knows wherein there is one for dialling the core wheel, but also uncertain when specifically which being, then every pair once number, also must rotate one one by one and set aside the core wheel, four wheels positive and negative each once then need rotate 8 times, therefore total test probability of unblanking is that 10 4 powers multiply by (1+8)=90000 time.Once calculate by per second, then needed the continuous test that did not stop in a second 25 hours, if 5 rollers (having only 4 wheels of checking the number actually), its test probability of unblanking is that 10 5 powers multiply by (1+10) and equal 110,000 times.So high safe coefficient is enough to allow the people beat a retreat in the face of difficulties, even have only three rollers, its probability also is that 10 3 powers multiply by (1+6)=7000 time.If the stranger has locked just that can't be opened forever not knowing wherein have under the situation of dialling the core wheel.

Added a dead bolt 9 and spring 7 in the endoporus of lock core 8 again, the active force of spring 7 acts on 9 two members of lock core 8 dead bolts simultaneously, and makes the active force of dead bolt 9 be close to draw-in groove on the lock bridge 5 all the time.This novel particular structure, though guaranteed the wheel of checking the number by accidental situation of aiming under, any knock vibrations and can not make dead bolt 9 break away from lock bridges 5, strengthened safety undoubtedly again.When locking, the inclined-plane of lock bridge 5 ends can make dead bolt 9 traversing, and after rebounding, dead bolt 9 just is stuck in the draw-in groove on the lock bridge 5.This process lock core 8 does not move, so need not aim at the trouble that number could insert lock bridge earlier.Must be just can open lock by the mobile drive dead bolt 9 of lock core 8 when unblanking, this also be the distinctive feature of this lock.

The beneficial features of this lock:

1, increases unique method for unlocking, had high security performance.

2, lock and unblank simply, convenient, quick.

3, be not afraid of rainwater, be not afraid of corrosion, malfunctioning phenomenon can not occur.

4, can the number of the wheel of checking the number be set arbitrarily according to security classification.

5, can be equipped with different lock bridges, as steel wire, chain, the shaft-like lock bridge and the u-beam of various length etc.

Description of drawings:

Fig. 1, Fig. 2, Fig. 3 are part drawing; Fig. 4 is a schematic diagram.

Among the figure 1, the wheel 2 of checking the number, dial core wheel 3, alignment pin 4, Luo silk hole 5, lock bridge 6, idle hole 7, spring 8, lock core 9, dead bolt 10, pilot hole 11, lock body 12, pin-and-hole 13, protruding tongue 14, inclined-plane 15, convex shoulder.

The specific embodiment

At first three 1 and one on wheels of checking the number are dialled core wheel 2 (because of the special construction of dialling the core wheel can only be arranged in second arbitrarily, the 3rd, on the 4th the position), place the square hole of lock body 11, again dead bolt 9 and spring 7 are assemblied in the endoporus of lock core 8, together insert then from pilot hole 10, just three check mark wheels and one group of core wheel are positioned on the lock body 11, with alignment pin 3 with the lock core fastening, lock core is not ejected, can make lock core only laterally move (can not rotate) again, last shutoff pilot hole 10 fixes on this locking on the bicycle by Luo silk hole 4 with an installation steel disc.When unlocked, lock bridge 5 can be inserted in the idle hole 6.

Claims (1)

1, a kind of bicycle coded lock, by the wheel (1) of checking the number, dial core wheel (2), lock core (8), dead bolt (9), spring (7), lock body compositions such as (11), interior circle one side of taking turns (1) that it is characterized in that checking the number has pin-and-hole (12), interior circle opposite side has protruding tongue (13), a side of dialling core wheel (2) has the inclined-plane (14) of protrusion, and the cylindrical of lock core (8) has convex shoulder (15), is equipped with spring (7) and dead bolt (9) in the interior circular hole.
