Abstract
The utility model discloses a three-safety lock cylinder, which comprises a lock cylinder shell, wherein at least two password holes for mounting password beads are formed on a side of the lock cylinder shell; the diameter of at least one of the password holes is different from the diameters of other password holes; and a transverse I-shaped groove for mounting a push rod is formed on the other side of the lock cylinder shell. The three-safety lock cylinder has the advantages of increasing the difficulty of cracking the lock cylinder or duplicating a key, and improving the using safety.
Description
Technical field
The utility model belongs to a kind of lock core, particularly is a kind of three safe lock cylinders.
Technical background
Key and lock core are used very extensive in daily life, and its kind is also a lot.The normally used key of people all is to rise and fall with spacing, height between the tooth and realize the pairing to different lock cores through changing on the key key bit shape and tooth; But in a single day this key is lost or is stolen by other people; Just duplicated by the people easily; Cause article lost in the family, safety is lower.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of three safe lock cylinders are provided.
For achieving the above object, a kind of three safe lock cylinders that the utility model provided comprise lock core shell, and an end of said lock core shell is provided with the draw-in groove that is used for fixing lock core, also are provided with the lockhole that is used to insert key on the side of the opposite side of lock core shell.
In addition; One side of said lockhole is provided with at least two code holes that are used to install the password pearl, and the diameter of the diameter of at least one code hole and other code holes is different in the said code hole, is provided with one in the said code hole and prevents that the password pearl from falling into the step of lockhole; Simultaneously; The opposite side of said lockhole is provided with one " worker " font groove, and an end of said " worker " font groove is provided with two through holes that are used to install push rod, is provided with first return spring and second return spring in the groove of said through hole opposite side.
When key is inserted lockhole, the password groove of key one side will be installed in the password pearl jack-up in the code hole, and concordant with the external surface of lock core shell, simultaneously; The key bit of key opposite side promotes cutting somebody's hair on the push rod and moves axially, and the return spring compression is identical with the shape of groove until the shape of push rod; This moment, push rod was concordant with the external surface of lock core shell, and door is opened, when extracting key; The password pearl that is installed in the lock core one side code hole partly falls into lockhole, and the password pearl that is installed in simultaneously in the lock tube partly falls in the code hole, part fall into password pearl in the code hole stopped lock core in lock tube axially with move radially; Therefore door is locked, and simultaneously, the push rod that is installed in the lock core opposite side is under the effect that return spring resets; On lock core shell, form convexity, organize the axial of lock core and move radially, in addition; Because the diameter of one of them code hole is different with the diameter of other code holes, for cracking of lock core increased one deck difficulty, thereby reaches the purpose of retrocession.
According to a kind of optimal way of the utility model, the push rod of installing on said first through hole and second through hole becomes " worker " font or " T " font structure, and is provided with at the push rod front end and cuts somebody's hair.
The remarkable result of the utility model is: increased the difficulty that lock core is cracked or key is replicated, improved the safety of using.
Description of drawings
Fig. 1 is the front view of the utility model;
Fig. 2 is the rear elevation of the utility model;
Fig. 3 is the lateral view of the utility model.
In the accompanying drawing, 1 is lock core shell, and 2 is draw-in groove, and 3 is code hole, and 4 is lockhole, and 5 is first return spring, and 6 is second return spring, and 7 is first through hole, and 8 is second through hole.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further described.
Like Fig. 1,2, shown in 3, a kind of three safe lock cylinders comprise lock core shell 1, and an end of said lock core shell 1 is provided with the draw-in groove 2 that is used for fixing lock core, also are provided with the lockhole 4 that is used to insert key on the side of the opposite side of lock core shell 1.
Wherein, One side of said lockhole 4 is provided with at least two code holes 3 that are used to install the password pearl; Be provided with one in the said code hole 3 and prevent that the password pearl from falling into the step of lockhole 4, simultaneously, the opposite side of said lockhole 4 is provided with one " worker " font groove; One end of said " worker " font groove is provided with two first through hole 7 and second through holes 8 that are used to install push rod, is provided with first return spring 5 and second return spring 6 in the groove of said through hole 7 and through hole 8 opposite sides.
During use, key is inserted lockhole, the password groove of key one side will be installed in the password pearl jack-up in the code hole 3, and concordant with the external surface of lock core shell 1; Simultaneously, the key bit of key opposite side promotes cutting somebody's hair on the push rod and moves axially, and the return spring compression is identical with the shape of groove until the shape of push rod; This moment, push rod was concordant with the external surface of lock core shell, and door is opened, when extracting key; The password pearl that is installed in the lock core one side code hole partly falls into lockhole 4, and the password pearl that is installed in simultaneously in the lock tube partly falls in the code hole 3, part fall into password pearls in the code hole 3 stopped lock core in lock tube axially with move radially; Therefore door is locked, and simultaneously, the push rod that is installed in the lock core opposite side is under the effect that return spring resets; On lock core shell 1, form convexity, organize the axial of lock core and move radially, in addition; Because the diameter of one of them code hole is different with the diameter of other code holes, for cracking of lock core increased one deck difficulty, thereby reaches the purpose of retrocession.
Certainly; The utility model also can have other various embodiments; Under the situation that does not deviate from the utility model spirit and essence thereof; Those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
