Abstract
The utility model relates to a key, whose body is a cylindrical body (1). The utility model is characterized in that an insertable toothlike guide groove (2) parallel to the round center of the cylindrical body of the key is formed at the edge of the cylindrical body (1); a toothlike guide angle opening (3) is formed at the opening end of the toothlike guide groove and favorable for insertion; anda positioning distance is reserved at the section away from the opening (3), an unlocking hole (4) is formed according to the largest tooth like angle, a plurality of secret key tooth shapes (5) with different shapes are arrayed downwards at a certain number, and the secret key tooth shapes are indexed at a certain angle. The key enables the repetitive rate of a secret key of a lockset to be lowest, so that the safety performance of the lockset is good.
Description
Technical field
The utility model relates to a kind of key.
Background technology
The key of lockset use at present mainly adopts flat-shaped breach shape, counterbore shape; It is owing to be subjected to lockset size restriction, and the key thread form of key energy layout itself is very limited, causes the repetitive rate of key of lockset very high, lockset safety performance is poor.
Summary of the invention
Technical problem to be solved in the utility model is: at the problems referred to above, provide a kind of a kind of key that repetitive rate is very low, lockset safety performance is good of key of lockset.
Technical solution of the present utility model: a kind of key, key body is characterized in that as cylinder 1 inserted a thread form gathering sill 2 that is parallel to the key cylinder body center of circle is arranged on cylinder 1 edge, the openend of thread form gathering sill has a thread form guiding angle opening 3, the convenient insertion; Leave orientation distance leaving mouthfuls 3 one sections, a unlocking port 4 according to maximum thread form angle is arranged then, down successively by a plurality of difform key thread forms 5 of certain numerical value array, key thread form 5 is according to certain angle-differentiated.The calibration of angle can be 15 °-90 °, and key thread form 5 calibration quantity can be 2-20, and key thread form 5 can be for also can be counterclockwise clockwise.Key thread form 5 is arranged according to certain array of values, and number of the arrangement is 2-15.
The utility model makes that the repetitive rate of key of lockset is very low, lockset safety performance is good.
