Abstract
The invention discloses a lockset. The lockset comprises a lock shell, a lock bar and a lock cylinder, wherein the lock shell is provided with the lock bar hole and the lock cylinder hole; the lock bar hole is communicated with the lock cylinder hole; the lock bar is arranged inside the lock bar hole and can move along the lock bar hole; the lock bar is provided with a lock pin groove; the lock cylinder is arranged inside the lock cylinder hole and is provided with a lock pin hole, a key hole and a billiard hole group; billiard groups are arranged inside the billiard hole group; and the billiard groups comprise first billiards, second billiards, third billiards and billiard springs which prop against the first billiards. When the lockset is unlocked, a key does not need to be turned, and as no dialing tooth channel is equipped, the purpose that the lock is technically unlocked by inserting a foreign body into the key hole under the condition that the billiards are not touched can not be achieved; and moreover the lock cylinder of the lockset is provided with the billiard groups including the first billiards, the second billiards and the third billiards, so that the key density quantity of the lock is increased, the lock is not easy to unlock, and therefore the security of the lockset is enhanced.
Description
Technical field
The present invention relates to lockset.
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 marble hole of lock core, has on the key the tartar of respective depth.The mode of unblanking is also roughly the same, and namely the height difference by key tooth flower moves up and down corresponding pellet, makes the height of each lock core marble be in interface place on lock housing and the lock core, and then screw key band movable lock core reaches the purpose of unblanking.This class is latched in the moving tooth passage, and in 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 simultaneously, and the lockset key density is diminished, and is opened by the locksmith easily, and safety is relatively poor.
Summary of the invention
According to an aspect of the present invention, provide a kind of lockset, having comprised:
Lock housing, lock housing are provided with latch arm hole and lock core hole, and latch arm hole and lock core hole are connected;
Locking bar is located in the latch arm hole and also can be moved along latch arm hole, and locking bar is provided with the lock pin groove;
Lock core, be located in the lock core hole, lock core is provided with lockpin hole, keyhole and at least one group of marble hole group, lock pin and lock pin spring are housed in the lockpin hole, the shape on lock pin top matches with the lock pin groove, the lock pin spring two ends are connected with the lockpin hole inwall with lock pin respectively, the marble hole group comprises the first marble hole, the second marble hole and the 3rd marble hole, the first marble hole and the 3rd marble hole are located at respectively the lockpin hole both sides and are communicated with lockpin hole respectively, the 3rd marble hole also is communicated with keyhole, the second marble hole is located on the lock pin, the first marble hole, the second marble hole and the 3rd marble hole be corresponding and successively connection one by one, the pellet group is housed in the marble hole group, the pellet group comprises the first pellet, the second pellet, the 3rd pellet and the marble spring that contacts the first pellet, the first pellet and marble spring are located in the first marble hole, the marble spring two ends are connected with the inwall of the first pellet with the first marble hole respectively, the second pellet is located in the second marble hole, the 3rd pellet is located in the 3rd marble hole, and the length of the second pellet is identical with the length of the second marble hole.
Adopt the lockset of above technical scheme when normal the unlatching, the key that will be complementary inserts keyhole.Along with going deep into of key, the 3rd pellet is mobile in the 3rd marble hole under the effect of on the key teeth.Simultaneously, the second pellet that contacts with the 3rd pellet and with the first pellet that the second pellet contacts to overcome respectively the elastic force of marble spring mobile in the second marble hole and the first marble hole.When key arrived accurately the position, the second pellet two ends were concordant with the lock pin surface, and the first pellet is with in the second pellet just in time enters corresponding the first marble hole and the second marble hole, and lock pin can be normally mobile in lockpin hole.Pull out locking bar this moment, lock pin overcomes lock pin spring under the effect of lock pin groove elastic force moves to lockpin hole is inner, and locking bar can move outside latch arm hole thus, thereby lockset is opened.Lockset is when locking, key with coupling inserts accurately position first, this moment, lock pin can move freely in lockpin hole, then locking bar was moved in latch arm hole, under the effect of lock pin spring, the lock pin top enters in the lock pin groove, extract at last key, the first pellet is mobile in the second marble hole under the effect of marble spring, enters to contact the second pellet behind the second marble hole and enter in the 3rd marble hole, lock pin is stuck, can't move in lockpin hole.Pull out locking bar this moment, because lock pin is in the lock pin groove, locking bar can't move, thus the lockset locking.
Because above-mentioned lockset key when opening does not need to rotate, and does not have the moving tooth passage, so can't in the situation of not bumping the son of moving, foreign matter be inserted keyhole the inner carry out skilled unlocking by the moving tooth passage.And the lock core of above-mentioned lockset is provided with the pellet group that comprises the first pellet, the second pellet and the 3rd pellet, makes the close quantitative change of lockset key large, is not easy to be unlocked, and has strengthened thus the safety of lockset.
In some embodiments, the second pellet two ends are the plane.The first pellet is the plane with the end that the second pellet contacts mutually, and the 3rd pellet also is the plane with the end that the second pellet contacts mutually.Thus, the pellet group of having avoided comprising the first pellet, the second pellet and the 3rd pellet is not when key mates, because lockpin hole inwall pressed home causes lockset to be opened by force.
In some embodiments, locking bar comprises locking bar main body and Handheld Division.But the locking bar main body is connected by disrupted configuration with the Handheld Division.Under larger External Force Acting, but the disrupted configuration fracture, locking bar main body and portion of the handle from.Can avoid thus locking bar is applied larger pulling force, destroy by force the pellet group and lock pin is pressed into lockpin hole causes lockset to be opened by violence.
In some embodiments, the locking bar main body is connected by demountable structure with the Handheld Division.Thus, the Handheld Division can be carried as key, only has key lockset can't be opened.
In some embodiments, lock core is provided with two rows or the above marble hole group of two rows, all is provided with in pellet group or the part marble hole group in the marble hole group and is provided with the pellet group.Thus, can greatly increase the key key density of lockset, strengthen the safety of lockset.
In some embodiments, be equipped with the pellet group in whole described marble hole groups.
