Abstract

An invisible marble anti-theft lock comprises a lock case, a key, a lock cylinder, a clamping bead, a marble hole and the like and is characterized in that the key consists of a key handle provided with two strong magnets, a cylindrical key shaft and a scraping slice fixed at the end part of the shaft and arranged in parallel with the shaft; the scraping slice is provided with a plurality of convex-concave grooves; the lock cylinder consists of an inner lock cylinder and a lock cylinder sleeve; the inner lock cylinder is arranged in the lock cylinder sleeve; the belly of the inner lock cylinder is provided with a key hole, the outer wall of the inner lock cylinder is provided with a circular groove, the length of the circular groove is adaptive to the length of the scraping slice and the periphery of the circular groove takes a 350-degree angle; and when the scraping slice rotates at 350 degrees through the circular groove, the convex-concave grooves on the scraping slice props up the marble in the inner lock cylinder and consequently props up the marble in the lock case. At the time, the lock cylinder is completely separated from the lock case, therefore, the lock cylinder can be then rotated. The anti-theft lock is simple in structure and low in cost, improves the anti-theft performance of locks and is suitable for being installed and used in large-scale warehouses and anti-theft doors and windows.

Description

The pellet shot from a slingshot hidden anti-theft lock

Technical field

The utility model relates to the lock field, particularly a kind of theftproof lock of pellet shot from a slingshot stealth.

Background technology

At present, known lockset anti-theft feature is lower, and its reason is exactly that the pellet shot from a slingshot that is provided with in the lock core is exposed in the lockhole, and the lawless person can assemble key according to its exposed situation and open lockset easily, thereby still there is the lower deficiency of anti-theft feature in present lockset.

Summary of the invention

In order to overcome above-mentioned deficiency, the utility model provides a kind of theftproof lock of pellet shot from a slingshot stealth, it is that a lock core cover is set outside inner key cylinder, and rotate the pellet shot from a slingshot that could will be hidden in the lock core cover behind 350 degree by special key and back down, the magnetic block that also will rely on the shank of the key two ends to be provided with simultaneously adsorbs two card pearls that are provided with between lock core cover and lock housing, after making the lock core cover and lock housing being separated, rotational lock core could be opened by a lock again, otherwise can't open.

The utility model solves technical scheme that its technical problem adopts: a kind of pellet shot from a slingshot hidden anti-theft lock, it comprises lock housing, key, lock core, card pearl etc., it is characterized in that: described key is by the shank of the key that is provided with two magnetic blocks and columniform key axle and be fixed in this shaft end and form with the scraping blade that this be arranged in parallel, described scraping blade is provided with some emboss pits, described lock core is made up of inner key cylinder and lock core cover, inner key cylinder is located in the lock core cover, the inner key cylinder belly is provided with keyhole, its outer wall is provided with cannelure, the length of described cannelure and the length of scraping blade adapt to, the circumference of described cannelure is 350 degree angles, described lock core cover sidewall is provided with some pellets shot from a slingshot hole, the emboss pit that is provided with on this pellet shot from a slingshot hole and the scraping blade adapts to, scraping blade is the center with the key axle, 350 degree turn clockwise in cannelure, can touch the pellet shot from a slingshot that adapts, described lock housing is enclosed within the outside of lock core cover, inwall one side of lock housing also is provided with some pellets shot from a slingshot hole, the pellet shot from a slingshot hole that described this pellet shot from a slingshot hole and lock core put adapts, two pellets shot from a slingshot are housed in each pellet shot from a slingshot hole, one in the lock core cover, one in lock housing, a spring respectively is housed in the pellet shot from a slingshot hole of lock housing, when lock is not opened, the part of every pellet shot from a slingshot in the lock housing is sprung in the lock core cover by spring, at this moment lock core just is stuck, when scraping blade is spent by cannelure rotation 350, pellet shot from a slingshot in the emboss pit jack-up inner key cylinder on the scraping blade, from and the jack-up lock housing in pellet shot from a slingshot, at this moment lock core separates fully with lock housing, get final product rotational lock core, described card pearl is located in the lock core cover and the positive card hole of bead that is provided with of lock housing, the magnetic block that is provided with on position of card pearl and the shank of the key adapts to, in the card hole of bead in the lock housing the more weak magnetite of magnetic is housed, when lock is not opened, the part of card pearl is inhaled in the lock housing card hole of bead, at this moment lock core just is stuck, when scraping blade just in time backs down pellet shot from a slingshot, magnetic block on the shank of the key will block pearl and all suck in the card hole of bead of lock core cover, at this moment lock core separates fully with lock housing, card pearl and pellet shot from a slingshot play the effect of double insurance, must open simultaneously just and can unblank.

The beneficial effects of the utility model are: simple in structure, with low cost, improved the lockset theftproof performance, and suitable bulk storage plant and security door, window are installed and used.

The specific embodiment

In example, lock housing 1 is enclosed within the outside of lock core cover 2, inwall one side of lock housing 1 is provided with some pellets shot from a slingshot hole 6, described this pellet shot from a slingshot hole 6 adapts with the pellet shot from a slingshot hole 6 that lock core overlaps on 2, two pellets shot from a slingshot 16 are housed in each pellet shot from a slingshot hole 6, one in 2 li in lock core cover, one 1 li of lock housing, a spring 15 respectively is housed in the pellet shot from a slingshot hole 6 of lock housing 1, when lock is not opened, the part of every the pellet shot from a slingshot 16 in the lock housing 1 is sprung in the lock core cover 2 by spring 15, at this moment lock core just is stuck, when scraping blade 8 is spent by cannelure 10 rotations 350, the pellet shot from a slingshot 16 that emboss pit 11 jack-up inner key cylinders on the scraping blade 8 are 3 li, from and jack-up lock housing 1 in pellet shot from a slingshot 16, at this moment lock core separates fully with lock housing 1, get final product rotational lock core, described card pearl 13 is located in the lock core cover 2 and the lock housing 1 positive card hole of bead 5 that is provided with, the magnetic block 7 that is provided with on position of card pearl 13 and the shank of the key adapts to, in the card hole of bead 5 in the lock housing 1 the more weak magnetite of magnetic 14 is housed, when lock is not opened, the part of card pearl 13 is inhaled in the lock housing 1 card hole of bead 5, at this moment lock core just is stuck, when scraping blade 8 backs down pellet shot from a slingshot 16, magnetic block 7 on the shank of the key will block pearl 13 and all suck in the card hole of bead 5 of lock core cover 2, and at this moment lock core separates fully with lock housing 1, and then lock is opened.
