Abstract
The utility model discloses a hidden marble-bead lock core, which comprises a lock-core shell and a rotating shaft, wherein at least one circular-arc-shaped hole is arranged in one surface of the lock-core shell, and the circular-arc-shaped hole is communicated with a hollow part in the middle of the lock-core shell; and meanwhile, a password hole for installing a password bead is arranged in each circular-arc-shaped hole, and a step for preventing the password bead from falling off is arranged in the password hole. The hidden marble-bead lock core has the remarkable effects that the difficult problem that a lock core and a key are easily cracked is solved, and meanwhile, the hidden marble-bead lock core has the advantages of simple structure, simple production process, convenience in mass production and strong practicability.
Description
Technical field
The utility model belongs to a kind of lock core, particularly is a kind of recessive pellet shot from a slingshot bead lock core.
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 recessive pellet shot from a slingshot bead lock core is provided, and it is mainly used in and solves the difficult problem that lock core and key are prone to be cracked, and simultaneously, it is simple in structure, and production technology is simple, is convenient to mass production, and is practical.
For achieving the above object, a kind of recessive pellet shot from a slingshot bead lock core of the utility model comprises lock core shell and axis of rotation; Said lock core shell is a hollow-core construction, is used to install axis of rotation, and lock core shell one end is provided with the draw-in groove that is used for fixing lock core; One side end face of said axis of rotation is provided with lockhole, and said lockhole is communicated with axis of rotation, and the lockhole periphery on the said axis of rotation opposite side end face is provided with screw thread; Said screw thread is used to connect packing ring and screw, is used to control the axially-movable of axis of rotation, wherein; The one side of said lock core shell is provided with at least one arc-shaped hole, and said arc-shaped hole is communicated with the middle hollow parts of lock core shell, simultaneously; Said each arc-shaped hole is provided with a code hole that is used to install the password pearl, is provided with a step that prevents that the password pearl from dropping in the said code hole.
According to a kind of recessive pellet shot from a slingshot bead lock core that the utility model provides, adopt a kind of key that has the comb tooth shape to match use with it, when opening the door, key is inserted lockhole and screw key; In rotation, key will be installed in the interior password pearl of code hole and the outer jointing jacket jack-up that makes progress, when key Rotate 180 °; Password pearl in the code hole is concordant with lock core shell, and door is opened, when taking out key; The reverse rotation key, when Rotate 180 °, key is released lock core along lockhole.
The remarkable result of the utility model is: solved the difficult problem that lock core and key are prone to be cracked, simultaneously, it is simple in structure, and production technology is simple, is convenient to mass production, and is practical.
Description of drawings
Fig. 1 is the structural representation of the utility model lock core shell 1;
Fig. 2 is the structural representation of the utility model axis of rotation 4;
Fig. 3 is the lateral view of the utility model axis of rotation 4.
In the accompanying drawing, 1 is lock core shell, and 2 is draw-in groove, and 3 is arc-shaped hole, and 3a is a code hole, and 4 is axis of rotation, and 5 is screw thread, and 6 is lockhole.
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 recessive pellet shot from a slingshot bead lock core comprises lock core shell 1 and axis of rotation 4; Said lock core shell 1 is a hollow-core construction, is used to install axis of rotation 4, and lock core shell 1 one ends are provided with the draw-in groove 2 that is used for fixing lock core; One side end face of said axis of rotation 4 is provided with lockhole 6, and said lockhole 6 is communicated with axis of rotation 4, and the lockhole periphery on the said axis of rotation 4 opposite side end faces is provided with screw thread 5; Said screw thread 5 is used to connect packing ring and screw, is used to control the axially-movable of axis of rotation 4, wherein; The one side of said lock core shell 1 is provided with at least one arc-shaped hole 3, and said arc-shaped hole 3 is communicated with lock core shell 1 middle hollow parts, simultaneously; Said each arc-shaped hole 3 is provided with a code hole 3a who is used to install the password pearl, is provided with a step that prevents that the password pearl from dropping in the said code hole 3a.
During use, lock core is fixed on the outer jointing jacket corresponding with lock core cipher hole 3a that has an endoporus, and puts into the password pearl in the hole within it; When opening the door, a kind of key that has the comb tooth shape is inserted lockhole 6 and screw key, in rotation; Key will be installed in password pearl in code hole 3a and the outer jointing jacket jack-up that makes progress, and when key Rotate 180 °, the password pearl in the code hole is concordant with lock core shell; Door is opened, when taking out key, and the reverse rotation key; When Rotate 180 °, key is released lock core along lockhole.
In technique scheme, because the password integument is hidden in the code hole, improved the difficulty that lock core is cracked and key is replicated, improved the safety of using, simultaneously, simultaneously, it is simple in structure, is convenient to produce in batches, and is practical.
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.
