Description
Technical field
The utility model relates to field of lockset, is the snakelike tapered end of a kind of blade specifically.
Background technology
The snakelike tapered end of existing blade generally has two kinds of structures, a kind of is to comprise the tapered end body, lock core, blade, on lock core, be provided with blade groove, blade is inserted in the blade groove, be provided with the alveolus structure of interworking between blade and the key, on facing the wall and meditating, the lumen side of tapered end body is provided with the draw-in groove that matches with blade, when extracting key out, the two ends of blade are concordant with the face of cylinder of lock core, can relatively rotate between tapered end body and the lock core, this kind lock has overcome the shortcoming of ball cylinder lock, but has adopted the two ends structure concordant with the face of cylinder of lock core of inserting the key rear blade, with dialling rod the alveolus structure on the blade is stirred to the draw-in groove direction of tapered end body, when blade pushes up draw-in groove, just can measure the permanent position of the alveolus structure on the blade, and, outwards move and dial rod because draw-in groove is a linear pattern, the waveform of the alveolus structure on the blade just can draw, be the waveform of key, be easy to key is duplicated, the security performance variation.The structure and the aforementioned structure of the snakelike tapered end of another kind of blade are basic identical, just blade groove is a groove, be placed with the blade that is in contact with one another in the groove, its blade of the tapered end of this structure is easy to install, blade quantity is many, and size of key still still can't prevent to draw the waveform of key by dialling rod than advantages such as height, key is duplicated, so security performance can't effectively be guaranteed.
Summary of the invention
The purpose of this utility model provides a kind of preventing and draws the waveform of key by dialling rod, and key is duplicated, and effectively improves security performance and the snakelike tapered end of blade simple in structure.
Further purpose is promptly to have high key amount, can effectively improve security performance again.
Further purpose is to have increased improper difficulty of stirring blade, and blade movement is more steady when unblanking.
The purpose of this utility model is achieved through the following technical solutions.
The snakelike tapered end of a kind of blade, comprise tapered end body, lock core, blade, be provided with blade groove on lock core, blade is inserted in the blade groove, is provided with the alveolus structure of interworking between blade and the key, on facing the wall and meditating, the lumen side of tapered end body is provided with the draw-in groove that matches with blade, lock core is installed on the tapered end body, inserts the rotatable lock core of key in the lock core, and it is characterized in that: described blade is provided with positive stop lug boss, be provided with on lock core and stop screens, positive stop lug boss can be installed on and stop in the screens.
Described positive stop lug boss is two positive stop lug boss.
Be provided with the bar shaped jump ring between described blade and the lock core.
Described positive stop lug boss is two positive stop lug boss, and lock core is provided with the jump ring groove and its notch faces toward the space bit that forms between two positive stop lug boss, and the bar shaped jump ring is stuck between the space bit of jump ring groove and the formation of two positive stop lug boss.
Alveolus structure on the described blade is a boss.
Alveolus structure on the described blade is open slot or back-shaped groove.
Described blade groove is a groove.
Described blade groove is provided with two groups or more.
Blade in described each group groove is arranged in contact
Only be provided with a blade in described each group groove.
Be provided with the controllable blade displacement in the described tapered end body and increase the spring that key enters the blade groove fluency.
The utility model compared with prior art has the following advantages.
The utility model is because blade is provided with positive stop lug boss, on lock core, be provided with and stop screens, positive stop lug boss can be installed on and stop in the screens, when insert to dial rod the alveolus structure on the blade when the draw-in groove direction of tapered end body is stirred, positive stop lug boss is stuck in and stops in the screens, forms straight line, can't measure the waveform of key, key is duplicated, therefore can effectively improve its security performance.
Again since blade groove be groove and be provided with two groups or more, the blade of each group in groove arrange in contact or each group groove in only be provided with a blade, increased size of key like this, can further improve the security performance of lockset.
Increase the spring that key enters the blade groove fluency owing to be provided with the controllable blade displacement in the tapered end body, so increased improper difficulty of stirring blade, blade movement is more steady when unblanking, and it is smooth more to unblank.

The specific embodiment
Below in conjunction with accompanying drawing the snakelike tapered end of the utility model blade is described in further detail.
Extremely shown in Figure 9 as Fig. 1, the snakelike tapered end of blade described in the utility model, comprise tapered end body 1, lock core 4, blade 3, be provided with blade groove on lock core 4, blade 3 is inserted in the blade groove, and blade groove can be a groove 9, be provided with one group or two groups or more, blade 3 is arranged in each group groove in contact, certainly, also a blade can only be set in each group groove.Be provided with the alveolus structure of interworking between blade 3 and the key 5, on facing the wall and meditating, the lumen side of tapered end body 1 is provided with the draw-in groove 2 that matches with blade 3, lock core 4 is installed on the tapered end body 1, insert the key 5 rotatable lock cores in the lock core 4, on blade 3, be provided with positive stop lug boss 6, on lock core 4, be provided with and stop that screens 7, positive stop lug boss 6 can be installed on and stop in the screens 7.
