The combination of novel preventing tool unlocking spring lock of the present invention and key has kept the structure of traditional mechanical lock substantially, and simple and reliable, easy to install, cost of production and technology do not have significant difference.

The specific embodiment is further described principle and enforcement below in conjunction with accompanying drawing:

One, the combination of preventing tool unlocking spring lock and key is characterized in that: 1, lock core keyhole is designed to

Shape; (Fig. 1) 2, increase by one group of anti-pellet shot from a slingshot of dialling, in lock core first row's pellet shot from a slingshot group the place ahead (Fig. 2,4) its diameter greater than the pellet shot from a slingshot of other group with

The base of type keyhole equates or greater than the base, the anti-precision of dialling between pellet shot from a slingshot and aperture is higher than other pellet shot from a slingshot group.Anti-pellet shot from a slingshot (Fig. 2, the 6) length down of dialling: the upper end flushes with the lock core marble aperture, and the lower end extremely

Type lock core keyhole bottom.3, novel key style.(Fig. 3, Fig. 4, Fig. 5) key design front portion is " ⊥ " type, and middle facade is established tartar, and the rear portion is Type, postmedian are provided with one and dial the strip open-work that the billiards diameter same lateral runs through key body with anti-.After key (Fig. 2,3) inserted lock core, the anti-pellet shot from a slingshot of dialling still can be fallen the lock core bottom, just in time coincide with open-work, and at this moment the same with the common spring lock, lock can be opened.Insert in the lock core hole if any objects such as unlocking tools, pellet shot from a slingshot (Fig. 2,6) will be lifted under anti-the dialling, and following pellet shot from a slingshot upper end enters in lock body (Fig. 2, the 1) hole, and this moment, lock was by locked.In fact anti-what dial that pellet shot from a slingshot plays a part is gate: the anti-pellet shot from a slingshot of dialling falls lock and can open, and the anti-pellet shot from a slingshot of dialling lifts lock and is closed.

For preventing to take to lift earlier the anti-pellet shot from a slingshot of dialling, stir the method for unlocking of other pellet shot from a slingshot again, the anti-precision of dialling between pellet shot from a slingshot and aperture is higher than other pellet shot from a slingshot group during design, when lock core (Fig. 2,2) is reversed, the anti-pellet shot from a slingshot of dialling contacts with hole wall earlier, after being lifted, other pellet shot from a slingshot also do not produce the frictional force between pellet shot from a slingshot and the hole wall, thereby fixing pellet shot from a slingshot.Further strengthen theftproof performance if desired, can be designed to two-section to anti-group pellet shot from a slingshot group of lock core and common spring group, be connected with two pins between the two-section, pin intensity is lower than common spring group pellet shot from a slingshot, and the anti-pellet shot from a slingshot group part of dialling should adopt the high-strength material manufacturing, when sled or brill lock core, pin will rupture, and has only the anti-one section lock core of pellet shot from a slingshot group of dialling to rotate thereupon, thereby reaches anti-pirate of the open purpose.

Two, in the lock core marble aperture arc groove and slide block are set, establish the pellet shot from a slingshot hole in the middle of (Fig. 6, Fig. 7, Fig. 8), groove (Fig. 2, the 9) degree of depth equals about the about 3mm of slide block thickness, groove is longer than slide block, make slide block can be in groove move left and right, shell hole center line with groove and slide block is the boundary, and an end one side that is designed to groove and slide block is than long two the pellet shot from a slingshot hole shapes of opposite side.Suppose that object inserts lock core and do not lift the anti-pellet shot from a slingshot of dialling, can stir other pellet shot from a slingshot again, fiddled with in the lifting process at other group pellet shot from a slingshot, when the pellet shot from a slingshot upper end flushes with the groove aperture instantly, because of last pellet shot from a slingshot (Fig. 2,5) lower end also in slider bore, under the twisting force of unblanking, lock core has a rotation, and lock is by locked.

Technical requirement on design: 1, unblank by force for prevention, pellet shot from a slingshot is also suitable under anti-the dialling makes with high rigidity rigidity material.2, the pellet shot from a slingshot lower end is designed to wedge type under anti-the dialling, and is beneficial to key and inserts and extract.The both sides, middle part are provided with a pair of alignment pin, and an alignment pin slideway is respectively opened before and after the place in anti-group of pellet shot from a slingshot hole of (Fig. 2,7) lock core, and (Fig. 2,8) prevents to dial pellet shot from a slingshot rotation down.3, lock core keyhole is advisable below being positioned at lock core kernel of section line, can increase pellet shot from a slingshot length down like this, not only can enlarge the secret key amount, also can take precautions against with chewing gum and so on material and unblank.4, in lock core under the no key situation, the common upper end design of pellet shot from a slingshot down guarantees that down pellet shot from a slingshot is lifted in the process upper port and must passes through the groove aperture in the groove aperture.4, because of slide block is shorter than groove, for preventing that when the key unlocking lock core rotates the common pellet shot from a slingshot of going up falls in the groove, and groove is become with slider designs

Type, when lock core rotated like this, last pellet shot from a slingshot can move past groove smoothly along slide block and groove inner edge.Can or all design on other pellet shot from a slingshot group except that anti-group pellet shot from a slingshot group groove and Slipper in addition.5, after preceding " ⊥ "

Open the key shape design of open-work in the middle of the type postmedian, after the postmedian perforate, the both sides oblique arm plays important interconnect function.Anterior " ⊥ " type purpose of design is to stop unlocking tool to insert from oblique arm hole, lock core both sides to stir pellet shot from a slingshot.The facade tartar also can be designed to double, increases the secret key amount.Key also can be designed to self-consistentency Shape, key open-work and the anti-pellet shot from a slingshot group of dialling also can design on any pellet shot from a slingshot group except that last row's pellet shot from a slingshot group, and can organize setting more.

Anti-group pellet shot from a slingshot group and key and groove, slide block two parts content are an integral body among the present invention, also can practice respectively.
