Abstract

A pin tumbler lock comprises a lock head, a curved groove lock cylinder, a pin, a driver, a pin spring, a sealing door, a brake bar, a vane, a vane spring and a curved groove key. Pin holes and vane holes in the lock cylinder are respectively formed in two sides of a key groove in the axis section direction of the lock cylinder. According to the pin tumbler lock, the pin and the vane are respectively installed on two sides of the key groove of the lock cylinder, the pin and the blade nearly have no interference with each other, and usable design space is large. As the usable design space is large, the pin holes are designed to be large in number, so that the number of secret teeth is greatly enlarged, the secret degree is greatly improved, and technique unlocking difficulty is enhanced.

Description

Cylinder lock

[technical field]

The utility model relates to lockset, exactly relates to a kind of cylinder lock.

[background technology]

In traditional cylinder lock, adopt T-shaped stereoscopic marble and with the homonymy of the round end pellet design key grooved on lock core.Because the direction of T-shaped stereoscopic marble and round end pellet is orthogonal, design in the same side of lock core key grooved, can only between across placement.The design of T-shaped stereoscopic marble like this has taken the space on the lock core, makes the usage quantity of T-shaped stereoscopic marble limited, and T-shaped cube pellet can only adopt the copper section bar to make, stereoscopic-state is complicated, and not only technique is cumbersome, and abrasion resistance is poor, differential few, close tooth number greatly reduces.

[utility model content]

In view of this, for addressing the above problem, the purpose of this utility model aims to provide the high cylinder lock of a kind of confidentiality.

A kind of cylinder lock comprises tapered end, curved groove lock core, round end pellet, tack pellet, marble spring, seals up a door, brake bar, blade, leaf spring and curved groove key.Round end marble hole on the described lock core and vane hole are separately positioned on the both sides of key grooved in the shaft section direction of described lock core.

Preferably, described blade is the L-type blade.

Preferably, described blade comprises three kinds of L-type blades different from groove location corresponding to described brake bar.

Cylinder lock of the present utility model designs respectively the both sides of key grooved on lock core with round end pellet and blade, does not almost respectively interfere with each other each other, and therefore available design space is just much older.Available design space is large, and the number of the marble hole of design is just many, and therefore close tooth number is just added greatly, and is a lot of thereby secrecy improves, and strengthened the technical opening difficulty.

[description of drawings]

Fig. 1 is the schematic diagram of preferred embodiment new marble lock of the present utility model.

Fig. 2 A, 2B, 2C are three kinds of schematic diagrames of the curved groove lock core among Fig. 1.

Fig. 3 A, 3B, 3C are respectively the schematic diagram of three kinds of states of the L-type blade shown in Fig. 1.

[specific embodiment]

In order to understand better the utility model, be described in detail below with reference to instantiation and the accompanying drawing embodiment to utility model.

For overcoming the defective of existing cylinder lock, the utility model provides a kind of novel cylinder lock, as shown in fig. 1, comprising: tapered end 1, curved groove lock core 2, round end pellet 3, tack pellet 4, marble spring 5, seal up a door 6, brake bar 7, L-type blade 8, leaf spring 9 and curved groove key 10.

Please in conjunction with consulting Fig. 1, tapered end 1 is the shell of cylinder lock.Curved groove lock core 2 is cylinder, and the above is designed with key grooved 22, marble hole 24 and vane hole 26(and sees also in detail Fig. 2).When key insertion lock core 2, flute profile is with pellet, when blade is corresponding, and brake bar 7 just can fall into the breaker slot of lock core 2, and key 10 just can rotate in the cylindrical hole of tapered end 1 with movable lock core 2, realizes the transmission of moment, realizes the open function of lock.

Please in conjunction with consulting Fig. 2, curved groove lock core 2 is separately positioned on round end marble hole 24 and vane hole 26 both sides (with the angle shown in Fig. 2 B, from the shaft section of curved groove lock core 2) of key grooved 22.Because round end pellet 3 is mutually vertical with the installation direction of blade, round end marble hole 24 and vane hole 26 separately are arranged on the heteropleural of key grooved 22, they almost respectively do not interfere with each other, so available design space is just much older.Available design space is large, and the number of the marble hole of design is just many, and therefore close tooth number is just added greatly, and is a lot of thereby secrecy improves, and strengthened the technical opening difficulty.

Please in conjunction with consulting Fig. 3, be respectively the structural representation of three kinds of blades that the utility model adopts shown in the figure.L-

type blade

8a, 8b, 8c adopt simple L-type shape plane structure, and the position of the groove of the corresponding brake bar 7 of three

blade

8a, 8b, 8c one side is different, also just represents differential difference.These three blades are carried out 8a, 8b, 8c combination, and drawn tartar secret number increases greatly.

In sum, cylinder of spring lock of the present utility model adopts round end pellet and the design that blade independently separates, and the progression of pellet is increased, and close tooth number increases, and has strengthened the technical opening difficulty.In addition, cylinder lock of the present utility model can change traditional four into six L-type plane blades by T-shaped three-dimensional copper marble, and shape and the manufacture craft of L-type blade are simple, can make of stainless steel, and abrasion resistance and anti-technical opening performance reason further improve.

The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
