Abstract

The invention relates to a fuzzy coded lock. The lock comprises a lock body and an arched lock beam, wherein a dial and a positioning point are arranged on the front surface of the lock body. The lock is characterized in that: three code wheels are arranged in the lock body and arranged on a loop bar of the dial; and a groove is formed on periphery of each code wheel. A groove is also formed on a beam head of the arched lock beam; an ejector rod is arranged in the lock body between the lock beam head and the code wheels; one end of the ejector rod leans against the top end of the lock beam head while the other end is hinged with a rotary shaft; and a hollow vertical bar is fixedly connected to the middle of the ejector. A ball is arranged at the top in the vertical bar; a T-shaped latch is positioned over the vertical bar; the left and right ends of the T-shaped latch respectively correspond to the groove on the lock beam head when the lock is locked and the grooves on the three code wheels when the lock is unlocked; a push rod exposed on the lock body is arranged on the upper part of the T-shaped latch; a sliding groove is formed at the bottom of the T-shaped latch; the spherical ball is positioned in the sliding groove; and a return spring is sleeved on the T-shaped latch. The fuzzy coded lock is safe and convenient and has high secrecy.

Description

Fuzzy coded lock

Technical field

The invention belongs to lock technology field, be specifically related to a kind of fuzzy coded lock.

Background technology

At present, along with The development in society and economy, the trend that lockset has unprecedented development to rise.The household decoration increases, and product tendencies such as door lock, hand holding lock, theftproof lock and hinge, door-inhale are better, and products such as chain lock, Pad lock for motorcycle and dish lock are liked by the customer also quite, sell considerable.But also there is certain problem in lockset, and these problems have also caused the attention of some lockset enterprises, constantly the lockset industry are carried out industrial upgrading, improve constantly product quality and safety, reliability.China is a bikedom, and the motorcycle of the cities of secondary grade, electric motor car use also comparatively extensive, and people lock bigger padlock antitheft through regular meeting on wheel; The glass door of StoreFront, pull gate, rolling-gate etc. also often use padlock, and therefore, the use of padlock is comparatively extensive; Sales volume is also higher; But at present big padlock still is the key unlocking type mostly, and this padlock is pried open easily, and safety is relatively poor.

Summary of the invention

The purpose of this invention is to provide that a kind of security performance is good from being difficult to distinguish true password in appearance, the padlock of the fuzzy password of employing easy to use.

The present invention realizes above-mentioned purpose through following technical scheme: this fuzzy coded lock, comprise lock body and arc lock bridge, and be provided with dial and anchor point in the front of lock body; Be characterized in: in lock body, be provided with three cipher wheel, cipher wheel is installed on the loop bar of dial, and the circumference of each cipher wheel is provided with a groove; One end and the rotating shaft of arc lock bridge are hinged, and the other end is the lock bridge head that can insert in the lock body lockhole, and the lock bridge head is provided with groove; Be provided with a push rod in the lock body between lock bridge head and cipher wheel, an end of push rod and the top of lock bridge head offset, and the other end and rotating shaft are hinged, the centre hollow montant that is connected; Ball is equipped with at top in the montant, is provided with spring jack-up ball under the ball in the montant; A T shape is inserted door bolt and is positioned on the montant; Its left end and the right-hand member groove on the lock bridge head when being in locking respectively are corresponding with the groove on three cipher wheel that are in when unblanking; Its top is provided with a push rod that exposes above the lock body, and its bottom is provided with chute, the left end of chute be one with the supporting spherical groove of the ball at montant top; The right-hand member of chute is one section straight shape groove, and spherical ball is positioned at chute; Be with back-moving spring slotting the latching of T shape.

For at night or the dark ground of light can conveniently use, on described dial, scribble phosphor powder.

The present invention has changed the digital cipher lock of traditional sense; Nil mark on dial; Disguise with height; And the safe ready more of unblanking has effectively prevented the phenomenon that the conventional digital password is revealed easily, can be widely used in bicycle, motorcycle, electric motor car, glass door, pull gate, rolling-gate etc.

Description of drawings

Fig. 1 is a structural representation of the present invention.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail.

Referring to Fig. 1, it comprises lock body 1 and arc lock bridge 2, is provided with dial 3 and anchor point 4 in the front of lock body 1, and anchor point 4 is used for locating the scale of dial 3.Visible by figure, overlappingly in the inside of lock body 1 be provided with three cipher wheel, be respectively cipher wheel 5, cipher wheel 6, cipher wheel 7.Three cipher wheel are installed on the loop bar 8 of dial 3, and the circumference of each cipher wheel is provided with a groove 9.The right-hand member of arc lock bridge 2 and rotating shaft 10 are hinged, and left end is the lock bridge head 12 that can insert in the lockhole 11 of lock body 1, and lock bridge head 12 is provided with groove 13.Be provided with a push rod 14 in the lock body 1 between lock bridge head 12 and cipher wheel; The top of the left end of push rod 14 and lock bridge head 12 offsets; Right-hand member and rotating shaft 15 are hinged, the centre hollow montant 16 that is connected, and a ball 17 is equipped with at the tops in the montant 16; Be provided with spring jack-up ball 17 under the ball 17 in the montant 16, make ball 17 ability flexible motion.A T shape is inserted door bolt 18 and is positioned on the montant 16; Its top is provided with a push rod 19 that exposes above the lock body 1; Its bottom is provided with chute 20; The left end of chute 20 be one with the supporting spherical groove of the spherical ball at montant 16 tops 17, the right-hand member of chute 20 is one section straight shape groove, spherical ball 17 is positioned at chute 20.Be with back-moving spring 21 slotting the latching of T shape.

Operating principle of the present invention is: at first, by changeing dial 3 zeroings clockwise, when the pellet shot from a slingshot on the cipher wheel 5 22 forwarded contact point to, zeroing finished, the counting beginning.Because the groove 9 on each cipher wheel is corresponding with certain number of dial 3, so dial 3 has the number of unblanking of three settings.When first number of the groove of cipher wheel 5 and dial 3 was identical, expression cipher wheel 5 was opened, when second number of the groove of cipher wheel 6 and dial is identical; Expression cipher wheel 6 is opened, when the 3rd number of the groove of cipher wheel 7 and dial is identical, representes that cipher wheel 7 is opened; At this moment, the groove of three cipher wheel is in the position of its left side self-consistentency, stirs push rod 19 to the right; Back-moving spring 21 is compressed, and the right-hand member of inserting door bolt 18 injects in the groove of three cipher wheel, and spherical ball 17 has slided in the dark slightly spherical groove of chute 20 left ends of slotting door bolt 18 bottoms this moment; Spherical ball 17 will be inserted door bolt 18 and withstood in the groove of three cipher wheel, and the left end of slotting door bolt 18 breaks away from the groove 13 on the lock bridge head 12, so can lock bridge 2 upwards be mentioned; Break away from lockhole 11, therefore, lock is opened.When locking; Lock bridge 2 is injected lockhole 11 downwards, and lock bridge head 12 is depressed push rod 14, and push rod 14 heads into spherical ball 17 in the straight shape groove of chute 20 right-hand members; The right-hand member of inserting door bolt 18 breaks away from the groove of three cipher wheel; The left end of inserting door bolt 18 inserts in the groove 13 on the lock bridge head 12, and back-moving spring 21 discharges, and lock is lockable.

For at night or the dark ground of light can conveniently use, on described dial 3, scribble phosphor powder.
