Description
Technical field
The utility model relates to a kind of lockset, relates in particular to a kind of plug-type locksets such as door, car that are applicable to.
Background technology
When people go out,, usually use to prevent that its lockset that moves from locking, prevent to be removed article, so lockset is a requisite safety protective tools in people's daily life by other people for the large piece article that is not easy to carry.The lock core that general lockset can be changed by shape and form with the snap close shell that the lock core changes shape adapts, use cylinder lock widely at present, in its snap close shell side wall spring and pellet shot from a slingshot are installed, pellet shot from a slingshot in the snap close shell side wall is corresponding with the pellet shot from a slingshot hole in the lock core, the pellet shot from a slingshot that adapts with key shape in the pellet shot from a slingshot hole of lock core, lock core is after inserting key, key can make the pellet shot from a slingshot in the lock core move along the pellet shot from a slingshot hole, corresponding relation based on the pellet shot from a slingshot length in key shape and the lock core, at this time the interior pellet shot from a slingshot of lock core all ejects the pellet shot from a slingshot in the snap close shell side wall pellet shot from a slingshot hole of lock core, contract to bead place, snap close shell side wall pellet shot from a slingshot hole, at this time, pellet shot from a slingshot in the snap close shell no longer blocks the rotation of lock core, lock can be opened.And for emerging plug-type lockset, because lock core is not to rotate, but in the snap close shell, pull out fully, so, if take the pellet shot from a slingshot as the lock core of rotary type, the pellet shot from a slingshot in the snap close shell will drop out snap close shell pellet shot from a slingshot hole owing to pulling out of lock core, can't continue to use, so, must solve lock core and pull out the problem that the back pellet shot from a slingshot can drop out.
The utility model content
(1) technical problem that will solve
Technical problem to be solved in the utility model provides a kind of snap close that can be applied to plug-type lockset, and lockset still can be kept perfectly when lock core was all pulled out, and can continue after in lock core is pressed into the snap close shell to use.
(2) technical scheme
In order to solve this technical problem, the utility model is taked following scheme:
A kind of snap close, comprise the snap close shell and be installed on the interior movable locker of snap close shell side wall, described movable locker comprises the card cap, compression spring and supporting seat, described snap close shell side wall has installing hole, described installing hole to the snap close inner opening less than the opening outside the snap close shell, described card cap is positioned at installing hole to snap close shell inner opening place, card cap nose shape and installing hole adapt to the shape of snap close shell inner opening, card cap afterbody is bigger than head, be stuck in the installing hole, described supporting seat is positioned at installing hole opening part outside the snap close shell, and described compression spring one end is installed on the supporting seat, and the compression spring other end withstands in the card cap afterbody.This snap close shell can be used in combination with plug-type lock core, the problem that drops of pellet shot from a slingshot in the time of lock core can not occurring and pull out.
Wherein, at least one side of described card cap head is the inclined-plane, is the dead bolt shape, and described card cap head is trapezoidal cap shape or cone cap shape.Such shape will be blocked crown in the snap close shell side wall when being convenient to lock core and slipping into, and avoid the card cap to stop slipping into of lock core.
Wherein, described snap close shell external surface is whole cylindrical or prismatic.
(3) beneficial effect
