Description
[technical field]
What the present invention relates to is a kind of lock, particularly be a kind of cylindrical type anti-theft lock.
[background technology]
At present, lockset is various in style on the market, and structure is different, performance is various, has a kind of and the most approaching theftproof lock of the present invention, also includes lock housing, lock core, the edge of lock core has lockhole, this lockhole is flat, is provided with lock cylinder aperture on lock core, and these lock cylinder aperture are communicated with into the chip lock cylinder aperture fully with lockhole, in described chip lock cylinder aperture, be provided with the locking plate that is complementary with it, the periphery circular arc of the two ends of locking plate and described lock core is complementary, and rotates with convenient, is provided with lead on described locking plate.The theftproof lock of this structure, its theftproof performance still is reasonable, but full communicating chip lock cylinder aperture is set on lock core, and its technology bothers very much, because its complicated technology, production efficiency reduces when just causing making this lock core.And the lockhole of its tabular must adopt flat key, and this flat key also will be offered gathering sill on key piece, make the key piece attenuation, causes key piece to damage easily.
[summary of the invention]
Problem in view of lock in the prior art exists the object of the present invention is to provide the more rational cylindrical type anti-theft lock of a kind of modern design and theftproof performance.For achieving the above object, the present invention takes following scheme to finish: a kind of cylindrical type anti-theft lock, include lock housing, lock core and locking plate, described lock-shell lining is provided with first groove vertically, described lock core is provided with cylindrical lockhole along the axle core, described locking plate is provided with lead, what it is characterized in that described lock core radially is provided with plural at least second groove along circumference, in described second groove, have the through hole that communicates with lockhole, described locking plate for the lock core circumference be complementary circular-arc, and place second groove of lock core, lead on the described locking plate passes the through hole in lock core second groove, on described locking plate, be provided with the 3rd groove, be provided with the 4th groove vertically in described lock core periphery, the degree of depth of the 4th groove is shallower than lock core second groove, and the 3rd groove on the 4th groove and the locking plate is complementary, be provided with spring on the flange between described two second grooves and in lock core the 4th groove vertically, in lock core the 4th groove vertically, be provided with lateral pin, the described lateral pin and first groove are complementary, and the side that lateral pin matches with first groove is circular-arc.
Vertically the 4th groove is symmetrical arranged with lock core shaft's core on the lock core.
With the key that above-mentioned cylindrical type anti-theft lock matches, it is characterized in that key body is cylindrical, and the strand gathering sill directly is set on columniform key body.
Among the present invention, circumference at lock core radially is provided with second groove, and at the 4th more shallow groove of the axial setting of lock core, such setting can not destroy the whole firmly performance of lock core, can be owing to beaing the destruction that causes lock core, and the setting of lateral pin in the setting of the 3rd groove on its locking plate, the four-axial groove, a kind of brand-new antitheft thinking all is provided, and its key body adopts cylindrical, has improved the fastness of key more, make its theftproof performance better, longer service life.The outside of its lateral pin is a circular arc, makes lock core more convenient when unblanking, and vertically the 4th groove is symmetrical arranged with lock core shaft's core on the lock core, has improved theftproof performance of the present invention more.
[description of drawings]
Further describe relevant embodiment of the present invention below more in conjunction with the accompanying drawings.
Fig. 1 is STRUCTURE DECOMPOSITION figure of the present invention;
Fig. 2 is the detailed structure view of lock core of the present invention;
Fig. 3 is provided with the structural representation of spring for lock core of the present invention;
Fig. 4 is the structural representation of key of the present invention.
[specific embodiment]
As shown in Figures 1 to 4, this cylindrical type anti-theft lock, include lock housing 1, lock core 5 and locking plate 3, described lock housing 1 inwall is provided with two first grooves 2 vertically symmetrically, described lock core 5 is provided with cylindrical lockhole 10 along the axle core, described locking plate 3 is provided with lead 14, described lock core 5 radially be provided with four second grooves 7 along circumference, in described second groove 7, have the through hole 8 that communicates with lockhole 10, described locking plate 3 for lock core 5 circumference be complementary circular-arc, and place second groove 7 of lock core 5, lead 14 on the described locking plate 3 passes the through hole 8 in lock core 5 second grooves 7, and lead 14 can move in this through hole 8, on described locking plate 3, be provided with the 3rd groove 4, be provided with the 4th groove 9 vertically in described lock core 5 peripheries, the degree of depth of the 4th groove 9 is shallower than lock core second groove 7, and the 3rd groove 4 on the 4th groove 9 and the locking plate 3 is complementary, be provided with spring 11 on the flange 15 between described two second grooves 7 and in lock core 5 the 4th groove 9 vertically, also promptly on the flange 15 between two second grooves 7, the position of lock core 5 axial the 4th groove 9 processes is provided with spring 11, in lock core 5 the 4th groove 9 vertically, be provided with lateral pin 6, the outside of described lateral pin 6 is circular-arc, make it when unblanking, rotational lock core 5 can make lateral pin 6 break away from first groove 2 in the lock housing 1 like a cork.Vertically the 4th groove 9 is symmetrical arranged with 5 cores of lock core on the lock core 5, and the 4th groove 9 is corresponding with two first grooves 2 of lock housing 1 inwall, makes the theftproof performance of this lock better.
With the key that above-mentioned cylindrical type anti-theft lock matches, its key body 12 is cylindrical, and on columniform key body 12 strand gathering sill 13 is set directly.The structure of this key can increase the firm performance of key, can make key impose the power of unblanking more like a cork again when unblanking.
When unblanking, insert key of the present invention, because the lead 14 on the locking plate 3 passes the through hole 8 in lock core 5 second grooves 7, when so key inserts, under the forced guiding effect of strand gathering sill 13, leads 14 all on the locking plate 3 all match with key gathering sill 13, the 3rd groove 4 on the locking plate 3 all is in a straight line, simultaneously, the 3rd groove 4 on the locking plate 3 is on same the center line with axial the 4th groove 9 on the lock core 5, at this moment, rotational lock core 5, lateral pin 6 can break away from first grooves 2 in the lock housings 1 and fall into locking plate the 3rd groove 4 and lock core shaft in the 4th groove 9, and rotational lock core 5 again, lock core 5 is rotated in lock housing 1, and reach the purpose of unblanking.When locking, backward rotation lock core 5 is when the lateral pin on the lock core 56 forwards the position of lock housing 1 inwall first groove 2 to, because the effect of spring 11, lateral pin 6 is pushed up in lock housing first groove 2, lateral pin 6 is between lock core 5 and the lock housing 1, pulls out key again, under the forced guiding of key gathering sill 13, the 3rd groove 4 on the locking plate 3 will be no longer point-blank, like this, just lock core 5 is blocked, reach the purpose of locking.
