Technical field

The utility model relates to a kind of lock gall block construction of being furnished with unsteady pearl key sheet.

Background technology

Pearl formula lock gall unit generally comprises the core groove and is placed in the interior pellet shot from a slingshot functional part of lock core body in the market, it is designed to when the key sheet pushes lock core body core groove, groove depth permanent position with key sheet surface, cooperate promotion pellet shot from a slingshot and pearl just to move with the inner spring of each row pellet shot from a slingshot functional part, working in coordination reaches parastate, and conducting is for unblanking.But its structure is familiar with by most of people, and especially some offenders have grasped the knack of illegally unblanking mostly, have brought the factors of instability to society.

Summary of the invention

The purpose of this utility model provides a kind of lock gall block construction of being furnished with unsteady pearl key sheet, has the lockset of this kind lock gall unit, the difficulty in the time of can increasing undesired reason and unblank.

For achieving the above object, the utility model is taked following design scheme: this lock gall block construction of being furnished with unsteady pearl key sheet, constitute by key sheet, pearl formula lock gall unit, pearl formula lock gall unit includes the core groove and is placed in the interior pellet shot from a slingshot functional part of lock core body, described key sheet appropriate position is provided with the pearl that floats, and is being provided with spring groove on the lock core body below its unsteady pearl position, key sheet insertion back.

The utility model has the advantages that: practical, the reliability height.

The specific embodiment

As shown in Figure 1 and Figure 2, the utility model is furnished with the lock gall block construction of unsteady pearl key sheet, is made of key sheet 1 and pearl formula lock gall unit, and pearl formula lock gall unit includes the core groove and is placed in the interior pellet shot from a slingshot functional part 2 of lock core body.Improvement of the present utility model is: (101 places, groove position) are provided with the pearl 102 (referring to Fig. 2, Fig. 3) that floats in key sheet appropriate position, are provided with spring groove 3 on the lock core body below the key sheet inserts its unsteady pearl position, back.

Operating principle of the present utility model is: at 101 places, key sheet groove position, increase the moving decorative pearl on top of an official cap 102 of an agglomerate tabling, in the key sheet pushes the core groove, except groove is worked in coordination, more need this agglomerate tabling pearl 102 to be pushed into the A1 position in the A2 position automatically, make the spring 3 in the lock gall rise the position, snap into and promote floating pearl 102 when floating pearl voluntarily up, key sheet groove position 101 is given in transmission continuously again, and reaching becomes a parastate, forms breakdown action.The state diagram that shown in Figure 4 is when non-unsteady pearl key sheet inserts lock core body, the pearl key that floats inserts lock gall and then forms stuck action.
