Search within the title, abstract, claims, or full patent document: You can restrict your search to a specific field using field names.
Use TI= to search in the title, AB= for the abstract, CL= for the claims, or TAC= for all three. For example, TI=(safety belt).
Search by Cooperative Patent Classifications (CPCs): These are commonly used to represent ideas in place of keywords, and can also be entered in a search term box. If you're searching forseat belts, you could also search for B60R22/00 to retrieve documents that mention safety belts or body harnesses. CPC=B60R22 will match documents with exactly this CPC, CPC=B60R22/low matches documents with this CPC or a child classification of this CPC.

Keywords and boolean syntax (USPTO or EPO format): seat belt searches these two words, or their plurals and close synonyms. "seat belt" searches this exact phrase, in order. -seat -belt searches for documents not containing either word.
For searches using boolean logic, the default operator is AND with left associativity. Note: this means safety OR seat belt is searched as (safety OR seat) AND belt. Each word automatically includes plurals and close synonyms. Adjacent words that are implicitly ANDed together, such as (safety belt), are treated as a phrase when generating synonyms.

Chemistry searches match terms (trade names, IUPAC names, etc. extracted from the entire document, and processed from .MOL files.)
Substructure (use SSS=) and similarity (use ~) searches are limited to one per search at the top-level AND condition. Exact searches can be used multiple times throughout the search query.
Searching by SMILES or InChi key requires no special syntax. To search by SMARTS, use SMARTS=.
To search for multiple molecules, select "Batch" in the "Type" menu. Enter multiple molecules separated by whitespace or by comma.

Technical field the present invention relates to a kind of mechanical lock master
Mechanical lockset in the background technology world today, substantially be to adopt the rotating structural principle pattern of cylinder, and be latest model, state-of-the-art product, do not break away from the constraint of this structural principle pattern yet,, so just inevitably there is the drawback on this structural principle, the i.e. operability of divulging a secret property and unlocking tool in the not real breakthrough on structural principle.Thereby the key that has caused present lockset to match, only just can open with these lock unlocking tools and the skill of unblanking accordingly, after these defects of lockset are utilized by thief, just caused the current ubiquitous phenomenon of unblanking to commit a crime to occur.
Summary of the invention the invention provides a kind of lock core of brand new principle, the crime of unblanking of the technical means of resisting robber (being that instrument is unblanked) that can not only 100%; The phenomenon of unblanking mutually that can also effectively stop key occurs.With this lock core, coordinate, can make traffic lock, rolling screen door lock, common door lock, Safet puzzle lock, all kinds of locksets such as Automotive lock.
The present invention forms diamond type lock core by lock core cavity, dead bolt, side cover plate, front shroud, and dead bolt is under the effect of lower end spring, and dead bolt head stretches out from upper end, after pressurized, can sink.Protecgulum strip front lock head, dead bolt moves back and forth between lock core cavity and side cover plate.Dead bolt plane has middle hypomere to have wide cut shallow grooves, as key socket.The marble hole that has or not regular distribution in groove, with marble hole in lock core cavity distribute identical, communicate, plane is joined, there is a shallow grooves in a narrow margin at wide cut groove center, has 4 to 5 of through holes in groove, and key is wide cut, plane, plain edge, sheet metal, there are upright double wedge 2 to 3 teeth side by side key surface center, be in line,, there are logical 2 to 3 of the counterbores of wearing between double wedge and two.The through hole (counterbore is marble hole) that has or not regular distribution in the plane on double wedge both sides, with the marble hole Distribution Pattern of lock core, about half is identical to communicate, and remaining marble hole of lock core is aligned on the dry wall of keyhole.When key inserts lock core, double wedge on the key just in time withstands on the lock hole in shallow grooves in a narrow margin, and locking pellet is backed down to enable possition.
The pellet of this lock core marble hole of operating principle dress, plays two kinds of effects, a kind ofly plays contraposition confirmation effect; The another kind of locking action that rises, identical with key hole communicate play contraposition confirmation effect.When key inserts after lock core, each hole is on the key confirmed to communicate with the contraposition on lock core, keeps the pellet original position motionless (being opening) in these holes, confirms that this key is for this lock core spouse; The locking pellet of this lock core is all under the occupy-place of the dry wall of this keyhole is passed, by lock-out state (being that pellet is between lock core cavity and dead bolt), be displaced to the state of opening an account, (be that pellet is returned to separately, in lock core cavity and dead bolt, make the two form section) realize the unlatching of this lock core; Transfer to after key, the contraposition of this lock core confirms that pellet, according in opening, locks pellet and by opening, is returned to lock-out state, completes the locking of this lock core.

The specific embodiment:
In the embodiment in figure 1, lock core cavity (1) is that a side is opening, and upper end has dead bolt (4) to stretch out hole (2), and the right upper and lower has side cover plate fixing screw hole (3).
In the example of Fig. 2, be lock core cavity (1) top view, it is placed in the middle that dead bolt stretches out hole (2), is rectangle, and there is side cover plate fixing screw hole (3) on right side.
In the embodiments of figure 3, dead bolt (4) upper end is semi-circular, and there is wide cut shallow grooves (6) middle hypomere side, on wide cut shallow grooves (6) baseplane, has again recessed shallow grooves in a narrow margin (7).
In the embodiment of Fig. 4, dead bolt (4) is head shield type, in figure, can find out that wide cut shallow grooves (6) is laterally distributed, occupied the very big area of dead bolt (4), there is shallow grooves (7) in a narrow margin centre, be level trend, in groove, there is lineal layout hole, in the plane of wide cut shallow grooves (6) both sides, what have or not wherein beat+word of regular distribution hole (being marble hole) symbol can not find their position for lock hole (19) on key (2), all the other are that contraposition confirms its hole number of hole (20), equal, identical with key with pore size distribution position, communicate.
In the embodiment planting at Fig. 5, lock core cavity (1), dead bolt (4), side cover plate (11) cooperation figure, the one side of dead bolt (4) plane is joined with lock core cavity (1) inner side plane, under the effect of lower end spring (9), lock tongue (5) stretches out in hole (2) and stretches out from dead bolt, the reeded one side of dead bolt (4), by side cover plate (11) plane, joined, make wide cut shallow grooves (6) form key socket, this lock core basic forming, can coordinate with U-shape lock.
In the embodiment of Fig. 6.Be the front shroud (16) of this lock core, be rectangle.One side of the tapered end of its column type (17), exceeds the width of front shroud (16), and there is the tapered end key socket (18) of vertical-type strip at tapered end (17) center.This lock core is loaded onto after this front shroud (16), just can make rolling screen door lock, common door lock, and safe lock.
In the example of Fig. 7, this lock core key (14), this key (14) is wide cut, plane, light face, thin slice, there is the linearity sector of suitable key trend at its center, on this straight line, has lattice distribution between through hole and double wedge, double wedge is 2 to 3, key (14) plane has disorder distribution counterbore, and (counterbore does not draw) its hole count and Distribution Pattern equate with lock core registration holes (20), identical, come round.
In the embodiment of Fig. 8, be the lateral view of this key, its key double wedge (21) stands on key (16) plane, forms with it right angle, and there is lattice distribution between through hole between double wedge and two.Cry key cathetus hole (15), this key (12) inserts after key socket (10), its key double wedge (21) top just in time with lock core in a narrow margin the lock hole (19) in shallow grooves aim at.
