Description
Technical field
The utility model relates to lockset, particularly a kind of double special-shaped cylinder lock and the key that is complementary with it.
Background technology
Lock is common anti-theft tool.Cylinder lock is simple in structure with it, practical and be widely used.The structure of cylinder lock is roughly the same, and one group of cylinder-shaped marble namely is housed in the pellet shot from a slingshot hole of lock core, has the tartar of respective depth on the key.The mode of unblanking is also roughly the same, and namely the height difference by key tooth flower moves up and down corresponding pellet shot from a slingshot, makes the height of each lock core marble be in interface place on lock housing and the lock core, and screw key drives lock core then, reaches the purpose of unblanking.This class is latched in the moving tooth passage, and under the situation of not bumping the son of moving, foreign matter can enter keyhole the inner easily, probes into various unlocking tools by the moving tooth passage, carries out skilled unlocking.This kind structure has been wasted the effective travel of pellet shot from a slingshot simultaneously, makes the close quantitative change of lockset key little, is opened by the locksmith easily, and safety is relatively poor.
The utility model content
The purpose of this utility model provides a kind of double special-shaped cylinder lock and the key that is complementary with it.
According to an aspect of the present utility model, double special-shaped cylinder lock is provided, comprising:
Lock housing is provided with lock core hole, and lock core hole is provided with two first lockpin holes;
Lock core, be installed in the lock core hole, lock core be axially arranged with keyhole with two with two second lockpin holes that first lockpin hole is corresponding, lock core is provided with along the pellet shot from a slingshot hole group that lock core radially arranges, pellet shot from a slingshot hole group comprises the first pellet shot from a slingshot hole and the second pellet shot from a slingshot hole, the first pellet shot from a slingshot hole and the second pellet shot from a slingshot hole are located at the keyhole both sides respectively and are communicated with keyhole respectively, and two second lockpin holes are communicated with the first pellet shot from a slingshot hole and the second pellet shot from a slingshot hole respectively;
Pellet shot from a slingshot is located in the first pellet shot from a slingshot hole and the second pellet shot from a slingshot hole, and pellet shot from a slingshot has lock pin groove and protuberance, and the lock pin groove is located at second lockpin hole, one side of pellet shot from a slingshot, and protuberance is located at keyhole one side of pellet shot from a slingshot and is stretched in the keyhole;
Lock pin is located in second lockpin hole, and lock pin one side has cambered surface, and opposite side shape and lock pin groove are complementary.
Adopt the double special-shaped cylinder lock of above technical scheme, after the key that is complementary inserted keyhole, the teeth groove of key and tartar acted on the protuberance of the pellet shot from a slingshot in the first pellet shot from a slingshot hole and the second pellet shot from a slingshot hole respectively.Pellet shot from a slingshot in the first pellet shot from a slingshot hole and the second pellet shot from a slingshot hole is along with the insertion of key is moved.After key inserts fully, the lock pin groove of the pellet shot from a slingshot in the first pellet shot from a slingshot hole is overlapped and be in same straight line, the lock pin groove of the pellet shot from a slingshot in the second pellet shot from a slingshot hole also is in same straight line simultaneously, this moment is rotational lock core a little, lock pin enters corresponding pellet shot from a slingshot hole and matches with the lock pin groove under the effect of lock housing, this moment, lock core can rotate, and lockset is opened.When the key that is complementary is extracted from keyhole, pellet shot from a slingshot in the first pellet shot from a slingshot hole and the second pellet shot from a slingshot hole is dialled unrest by the teeth groove of key and tartar, thereby the lock pin groove staggers mutually and lock pin is released the lock pin groove, lock pin is stuck between second lockpin hole and first lockpin hole, this moment, lock core can't rotate the lockset locking.
Because the lock core of above-mentioned lockset is provided with two row's pellet shot from a slingshot and two lock pins, has increased the key key density greatly, be difficult for being opened high safety by the locksmith.And lock pin is hidden in the lock core, is not easy to touch from the outside and by outside destroy.Two lock pin mutual restriction, only when the both entered corresponding lock pin groove, lock core could rotate, and lockset could be opened.Owing to can't accurately judge unlatching or the lock-out state whether two lock pins are in, if do not use the key that matches, will be difficult to because of having no way of doing it open, thereby effectively contain with improper mode technical unlocking lockset.
In some embodiments, the first pellet shot from a slingshot hole is equipped with first marble spring.The first marble spring two ends are connected with pellet shot from a slingshot in being installed on this first pellet shot from a slingshot hole with the first pellet shot from a slingshot hole respectively.Thus, when the key that is complementary was extracted from keyhole, the pellet shot from a slingshot in the first pellet shot from a slingshot hole can reset rapidly under the effect of spring.
In some embodiments, the second pellet shot from a slingshot hole is equipped with second marble spring, and the second marble spring two ends are connected with pellet shot from a slingshot in being installed on this second pellet shot from a slingshot hole with the second pellet shot from a slingshot hole respectively.Thus, the pellet shot from a slingshot that is installed in this second pellet shot from a slingshot hole can move at the tartar of the effect lower edge of spring key.
In some embodiments, first lockpin hole is equipped with lock pin pellet shot from a slingshot and lock pin spring, and the lock pin pellet shot from a slingshot contacts mutually with lock pin, and the lock pin spring two ends are connected with lock pin with first lockpin hole respectively.Thus, when the key that is complementary inserted fully, lock pin can enter corresponding pellet shot from a slingshot hole and match with the lock pin groove under the effect of lock pin pellet shot from a slingshot and lock pin spring.
According to an aspect of the present utility model, the key that provides a kind of and double special-shaped cylinder lock to be complementary comprises key main body and the shank of the key.The key main body is provided with teeth groove and tartar, and the protuberance of the pellet shot from a slingshot in teeth groove and the first pellet shot from a slingshot hole matches, and the protuberance of the pellet shot from a slingshot in tartar and the second pellet shot from a slingshot hole matches.
