Abstract
The utility model discloses a blade marble which comprises a body, wherein the end part of the body is provided with a lug which is matched with a return spring; the inner side of the lug is provided with a positioning pin used for fixing the return spring, and the lug which is matched with the return spring is provided with the positioning pin; the return spring is firstly sleeved on a fixing pin to fix when the blade marble is assembled, and then the return spring and the blade marble are assembled on a lock core so as to improve the assembly efficiency; the return spring is always fixed on a blade, and the return spring and the blade marble can not stagger in a using process; and the situation that the blade marble lapses and can not open a lock because the return spring is damaged can be avoided, and the reliability of the lock is improved.
Description
Technical field
The utility model belongs to lockset, particularly a kind of blade marble.
Background technology
The employed outer tooth blade marble of existing blade spring lock head is as shown in Figure 1; Comprise body 1, be provided with projection 3, when blade marble is assemblied on the lock core in the end of body 1; Its return spring 2 is contained in the spring eye, and the projection 3 of blade marble is pushed down return spring 2.Because the spring eye bore on the lock core is less; Spring is difficult for installing when assembling; Projection 3 because of blade marble can stretch out lock core (stretching into lock shell lock lock core) repeatedly in use; Make to misplace repeatedly between spring and the blade marble and the lockhole of emerging, cause spring easy deformation and damage, cause the malfunctioning and lock of not opening of blade.
The utility model content
The purpose of the utility model just provides a kind of convenient for assembly, can prevent that spring from damaging, and improves the blade marble of lock reliability.
Realize that the technical scheme that the utility model purpose adopts is: blade marble comprises body, and the end of body is provided with the projection that cooperates with return spring, is provided with the location nail that is used for fixing return spring in said projection inboard.
Said location nail is taper.
The utility model since with projection that return spring cooperates on be provided with the location nail, first return spring is enclosed within on the staple fixed during assembling, and then is contained on the lock core with blade marble, can improve efficiency of assembling.Because return spring is fixed on the blade all the time, the situation that dislocation takes place for return spring and blade marble in use can not occur again, can avoid return spring to be damaged and cause the phenomenon that blade marble lost efficacy and lock is not opened to take place, improve the reliability of lock.
