Description
Technical field:
The utility model relates to field of lockset, the special-purpose tapered end that relates in particular to a kind of special-section key and match with it.
Background technology:
At present, the lockset on the market of a great variety, structure is different, and what wherein use in people's life is cylinder lock the most widely.The tapered end of cylinder lock of the prior art mostly is made up of lock body, lock core and pellet shot from a slingshot assembly, and lock core is provided with keyhole.Its operating principle is, when inserting with the corresponding key of this tapered end, the key flank of tooth and each pellet shot from a slingshot are corresponding one by one, makes the height of each pellet shot from a slingshot all be in the contact surface place of lock body and lock core, and rotational lock core can be unblanked again.Mostly be plate shaped, cross and semilune etc. greatly with regard to the profile of the main body of the key of common cylinder lock, defective such as easy imitation, quality of fit are low, mutual opening rate height that it in use exists.And this tapered end is difficult to the person of avoiding theft and utilizes corresponding instrument such as Unlocking gun, steel disc, screwdriver etc. to insert keyhole, stirs even destroy the pellet shot from a slingshot in the lock core, will lock unlatching by force, and its theftproof performance is relatively poor.And the lock core of cylinder lock of the prior art and key generally adopt machine tooling, and its workload is big, and production efficiency is low.
The utility model content:
The technical problems to be solved in the utility model is, a kind of fitness height, mutual opening rate is low, theftproof performance is good special-section key and tapered end are provided.
For solving above-mentioned technical problem, the utility model special-section key and tapered end, described special-section key comprises main body and afterbody, and described main body comprises first surface, second surface, first side and second side, and described main body is provided with the key bit that distributes along the principal length direction; Described tapered end comprises shell, lock body, be provided with the lock core of keyhole and the pellet shot from a slingshot assembly that is complementary with key bit on the main body of special-section key, the cross section of the main body of described special-section key is a waveform, this cross section is made up of three arc wave bands, and first side of described main body is provided with first key bit, and the arc top of the first surface of described main body is provided with second key bit; The shape that the cross section of keyhole is complementary for the shape with the body cross-section of above-mentioned special-section key on the described lock core; Described pellet shot from a slingshot assembly is two row.
After adopting said structure, the utlity model has following advantage:
The cross section of the main body of special-section key is set to waveform, this corrugated cross section is made up of three arc wave bands, and in first side of main body, first surface and second surface are respectively equipped with first key bit, second key bit, because being the asymmetric distribution of irregular structure and key bit, the overall profile of main body make this special-section key be difficult to copy, and the shape that the cross section of keyhole also just is complementary for the shape with the body cross-section of above-mentioned special-section key on the lock core, this just makes this special-section key and keyhole have very high fitness, and the person that can effectively not avoid theft utilizes the tool technique unlatching, its theftproof performance height, easy to use.Pellet shot from a slingshot assembly in the tapered end has two row, and arranging rationally of pellet shot from a slingshot also makes special-section key have bigger size of key, and like this, the theftproof performance of tapered end increases substantially, and the mutual opening rate of special-section key reduces significantly.Special-section key of the present utility model in addition and lock core adopt the processing method of mould molding (i.e. cast), and be easy to process, and guaranteed the required precision of structure.
As improvement, at the bottom of two arcs on the first surface of the main body of described special-section key with second surface on arc at the bottom of on same straight line.Like this, can guarantee that the main body of special-section key has reliable intensity, and make straight thin slice can not insert in the keyhole, the theftproof performance of tapered end is better.
Improve as another kind, described every row pellet shot from a slingshot assembly is made up of seven groups of pellet shot from a slingshot groups, and described every group of pellet shot from a slingshot group is made up of a spring, a locking pellet shot from a slingshot and a movable pellet shot from a slingshot respectively.Because every row pellet shot from a slingshot assembly is made up of seven groups of pellet shot from a slingshot groups, can guarantee that special-section key has enough size of keys, the mutual opening rate of special-section key is lower.
