Specific implementation mode

The utility model embodiment is described further below in conjunction with the accompanying drawings.

As shown in Figures 1 to 6, a kind of tapered end, including lock housing 1, middle lock core 2 and internal cylinder 3, the internal cylinder 3 are placed in middle lock In core 2, middle lock core 2 is placed in lock housing 1, and the center of the internal cylinder 3 is equipped with lockhole 4, the lock housing 1, middle lock core 2 and interior It is equipped with hollow structure 5 inside lock core 3, and is equipped with through-hole 6, the hollow knot between hollow structure 5 and the inner surface of its ontology Structure 5 is built-in with drier 7, and drier 7 is absorbed by through-hole 6 there are the humid air in lock core, makes to be to keep dry inside lock core Dry, specifically, the drier absorbs the humid air between lock housing 1 and middle lock core 2 by the through-hole 6 in lock housing 1, does Drying prescription 7 can be passed through by the humid air in the absorption of the through-hole 6 on middle lock core 2 between lock core 2 and internal cylinder 3, drier 7 Through-hole 6 in internal cylinder 3 absorbs existing humid air in lockhole 4, it is preferable that lime drying can be selected in drier 7.The lock 1 end of shell is equipped with capping 8, and folding protective cover 9 is equipped at 8 centers of the capping, and the protective cover 9 is made of left and right two parts, And left and right two parts are magnetic, and attract each other, and remote spring controlled structure, the structure are substituted with the principle that magnetism attracts each other Advantages of simple is designed, efficiency of assembling is high, reduces production cost.The lock core 3 is equipped with sensing device, sensing device connection alarm Device, it is preferable that alarm connects time-delay relay, and the sensing device is induction coil or RF transmitter, is passed through When induction coil perceives key or is inserted into lockhole 4 similar to the thing of key, it is connected to alarm in relay setting time, reports Alert device alarm, for example setting time is 5 seconds, the thing of key or similar key is inserted into lockhole 4, is reported at once in 5 seconds to extract It is alert, it is just alarmed before thief can not yet open lockset, it is safe, while user oneself can also be reminded to have used Complete key is extracted in time.

The protective cover 9 is coaxial arrangement with lockhole 4, and key body 11 will can enter lockhole 4, key by protective cover 9 Spoon ontology 11 is extracted, and protective cover 9 is momentarily turned off by magneticaction, clean in effective guarantee lockhole 4.

The capping 8 is equipped with the space groove 10 slided for protective cover 9, and protective cover 8 is during keying all in space Sliding in slot 10.

9 or so two parts of the protective cover relative at, and two parts contact with each other place outer surface be equipped with globoidal structure 91, The setting of globoidal structure 91 is easy for key body 11 and finds lockhole 4 accurately and be inserted into.

The lock housing 1 is equipped with marble hole 111 and built-in spring 22 and little spring 23, the middle lock core 2 and internal cylinder 3 On be respectively equipped with one group of marble hole 111, pellet 24 is equipped in marble hole 111, the edge of the lockhole 4 is provided with elongated slot 41, and Identical as lockhole 4, elongated slot 41 is matched with the pellet 24 on middle lock core 2, the marble hole on the middle lock core 2 and internal cylinder 3 111, it is interconnected when unlocking, 111 hole count of marble hole is than the marble hole 111 and lock housing on middle lock core 2 in the internal cylinder 3 111 hole count of marble hole on 1 is 1 few.

A kind of key includes key piece ontology 11, and the front end of the ontology 11 is equipped with blind hole 14, and the tail end of ontology 11 is equipped with Hole 13, and hole 13 is communicated with blind hole 14, and magnetic isolation plate 12 is equipped in the blind hole 14,12 entirety of the magnetic isolation plate is built entirely within blind In hole 14, the key body 11 can be inserted into the built-in magnetic isolation plate 12 in the part in lockhole 4, by an iron wire or other minor diameters Club object, the magnetic isolation plate 12 that through hole 13 is opposite in blind hole 14 apply outside power, you can take out magnetic isolation plate 12, structure letter It is single, it is practical, replace 12 convenience of magnetic isolation plate.

A front surface and a side surface of the key body 11 is equipped with tartar, front tartar and the bullet in internal cylinder 3 of the ontology 111 photograph of sub-aperture coordinates, and the side tartar of key body 11 is matched with the marble hole 111 on middle lock core 2, with key body 11 The larger and one side with tartar of area is front tartar, and adjacent with front tartar and one side equipped with tartar is side tartar.

When unlocking, key body 11 is inserted into lockhole 4, pellet 24 and the 11 front tartar phase of key body of internal cylinder 3 After cooperation, under the action of 11 inner spring 22 of marble hole of lock housing 1, internal cylinder is pushed by the pellet 24 of lock housing 1 and middle lock core 2 3 pellet 24 when the end of the pellet 24 of internal cylinder 3 being made all to be overlapped with foreign aid's week arc surface of internal cylinder 3, rotates internal cylinder 3, so that the pellet 24 on middle lock core 2 is all matched with 11 side tartar of key body by elongated slot 41, the pellet on middle lock core 2 24 end faces are also all overlapped with the excircle arc surface of middle lock core 2, since the pellet 24 of middle lock core 2 is stuck in the elongated slot of internal cylinder 3 In 41, it is rotated further internal cylinder 3, you can lock core 2 rotates in drive, and achievees the purpose that unlocking.

The utility model effectively improves existing lockhole 4 and is easy that dust or sundries enter and lock core moisture-sensitive is got rusty and influenced Advantages of simple is arranged in the problem of use, the tapered end and Key structure, dust and sundries can be effectively prevent to enter lockhole 4, simultaneously Also it effectively prevents lock core internal wetted from getting rusty, extends the service life of lockset, magnetic isolation plate built in key is prevented in opening process Only damaged due to the friction with protective plate, it is highly practical；There is induction warning device simultaneously, safety box can be not yet turned in thief When, find that tapered end is invaded by people, is alarmed in time, to prevent Safe lock stolen, security performance is high, easy to spread.

Every technical staff's notice：Although the utility model is described according to above-mentioned specific implementation mode, this The invention thought of utility model is not limited to that utility model, any repacking with inventive concept will all be included in this specially In sharp scope of patent protection.
