Abstract

The composite pellet consists of pellet sleeve, pellet core and spring, and the pellet core can slide inside the pellet sleeve. When some axial force is applied to the pellet, the pellet core extends partially beyond the pellet sleeve to enclose the interval between the pellet and the outside edge of lock core. The composite pellet, when matched with available cylindrical pellet, raised pellet and I-shaped pellet, can protect snap lock from being opened by "unlocking gun". It may be widely used in various snap locks.

Description

A kind of composite pellet of used for spring lock

The present invention relates to the composite pellet of a kind of parts of lock, particularly a kind of used for spring lock.

Pellet shot from a slingshot is the core component of cylinder lock, is exactly in fact operation to pellet shot from a slingshot to the open operation of cylinder lock.Cylinder lock is by lock body, lock core, and is made up of many pellet shot from a slingshot groups that lock core marble, lock spring, lock core marble hole, lock marble hole and marble spring are constituted.The pellet shot from a slingshot group can be one group, also can be many groups, but operating principle all is identical, and promptly in off position the time, lock spring embeds in the lock core marble hole under the effect of marble spring, and lock core can not freely be rotated; When the unlatching lock, key inserts lock core, and key bit jack-up lock core marble ejects the lock core outward flange to the lock spring that embeds lock core marble hole just by lock core marble, and the turn key just can drive the lock core rotation again, and lock is opened.The pellet shot from a slingshot (comprising lock core marble and lock spring) of cylinder lock use at present mainly is a cylinder-shaped marble, taper pellet shot from a slingshot, convex pellet shot from a slingshot, I-shaped pellet shot from a slingshot.Use the cylinder lock of cylinder-shaped marble, present various improvement can only prevent that all a kind of master key of multiple tooth likeness in form comb formula from opening it, also can't prevent effectively its unlatching for the master key of monodentate class.Use the cylinder lock of convex pellet shot from a slingshot and I-shaped pellet shot from a slingshot, can prevent multiple tooth effectively and unlatching monodentate class master key.But the so-called Universal opener lock tool that has newly occurred a kind of being referred to as " Unlocking gun " at present.Use the cylinder lock of cylinder-shaped marble very easily to be opened by this " Unlocking gun ".Use the cylinder lock of convex pellet shot from a slingshot and I-shaped pellet shot from a slingshot,, can't thoroughly prevent the unlatching of " Unlocking gun " though the unlatching difficulty is bigger when opening with " Unlocking gun ".

Order of the present invention and being: a kind of composite pellet of used for spring lock is provided, and as lock spring and existing cylinder-shaped marble, it is right that convex pellet shot from a slingshot or I-shaped pellet shot from a slingshot are made into pellet shot from a slingshot by this composite pellet, and the cylinder lock that is constituted can prevent the unlatching of " Unlocking gun ".

For achieving the above object, the invention provides a kind of composite pellet of used for spring lock, it comprises: marble sleeve, pellet shot from a slingshot core and pellet shot from a slingshot core bullet Huang, described pellet shot from a slingshot core can slide in described marble sleeve, and under the spring force effect of described pellet shot from a slingshot core spring, the pellet shot from a slingshot core can partly stretch out marble sleeve, the shape of described pellet shot from a slingshot core can be a T shape or cylindrical, also can be spill in concave shape or the evagination.The spring force of described pellet shot from a slingshot core spring is less than the yellow power of the bullet of marble spring in the cylinder lock of being packed into, under with this bitting normal condition, open when having the cylinder lock that composite pellet constituted of a kind of used for spring lock of the present invention, the pellet shot from a slingshot core is arranged in marble sleeve, composite pellet just in time is positioned at the interface place of lock core and lock body towards the end face of lock body direction, and twisting lock core marble lock is unlocked.

When opening the cylinder lock of the composite pellet that a kind of used for spring lock of the present invention is housed with " Unlocking gun ", lock core is applied a torsion, make the dislocation of lock marble hole and lock core marble hole, again to pellet shot from a slingshot to along pellet shot from a slingshot to axially applying a vibration force, under the conduction of power, lock spring the gap occurs towards the end face and the lock core outward flange of lock core, at this moment, the pellet shot from a slingshot core that is contained in the composite pellet of a kind of used for spring lock of the present invention in the lock core stretches out marble sleeve in the effect lower part of inertia and pellet shot from a slingshot core spring and enters lock marble hole, seal the gap between lock core outward flange and lock spring end face, made cylinder lock not open.

Compared with the prior art: the present invention is owing to adopted a kind of pellet shot from a slingshot core to slide in marble sleeve, running into along pellet shot from a slingshot during to axial vibration force, the pellet shot from a slingshot core can partly stretch out the composite pellet of marble sleeve, makes to use the attempt of " Unlocking gun " unlocking spring lock not realize.Use the present invention can be under the situation that not change existing billiards lock structure, a pellet shot from a slingshot that only needs to change respective numbers get final product, has simple in structurely, is convenient to production, and safe and reliable characteristics can be widely used in the various cylinder locks.

Below in conjunction with accompanying drawing two specific embodiment of the present invention are described in further detail.
