Description

A kind of L shaped cylinder anti-theft lock end

The utility model relates to a kind of L shaped cylinder anti-theft lock end.Mainly be that prior art has been done improvement.

Selling the comparatively advanced lockset that uses in the market is four prismatics locks, the design feature of this lock is that the pellet shot from a slingshot that is provided with in lock core is 90 degree, key is a cross shape, though this lock has increased the tooth of lock core marble and key, improved size of key, utilized the decorative pearl on top of an official cap will seal pearl just to head in the lock housing, lock is opened but remain on the structure, therefore anti-foreign matter is opened ability, only taking a lot of work during the foreign matter breakdown more.

The purpose of this utility model provides the new structure principle theft prevention lock of a kind of manufacturing simple in structure, easy, anti-foreign matter unlatching.

The utility model is realized by following scheme.To being set, a row L shaped pellet shot from a slingshot hole and arranges the cylindrical billiard hole along depth in the lock body, and corresponding respectively L shaped pellet shot from a slingshot and the cylindrical billiard of being equipped with; In the lock core along depth to two row's cylindrical billiard holes are set, the L shaped pellet shot from a slingshot hole in a row and the lock body is to logical, the cylindrical billiard hole in another row and the lock body all is equipped with cylindrical billiard to logical in this two round.And L shaped pellet shot from a slingshot hole between the cylindrical billiard in the logical cylindrical billiard hole and the L shaped pellet shot from a slingshot centre pellet shot from a slingshot is housed, one of middle pellet shot from a slingshot is in lock core, the other end contacts with L shaped pellet shot from a slingshot in lock body.After inserting " one " font two sides teeth key in the key in lock body, tooth of key contacts with L shaped pellet shot from a slingshot and forces L shaped pellet shot from a slingshot to move away from the lock core outward direction, abdicating the space of whole middle pellet shot from a slingshot comes, cylindrical billiard in the lock core is because of spring action ejects lock core with middle pellet shot from a slingshot, and pellet shot from a slingshot just all enters lock body in the middle of allowing.Meanwhile, key another side tooth pushes up another row's cylindrical billiard to open-part, firmly presses handle, and lock core is moved to depth, by the gear mechanism in the rack drives lock assembly that links to each other with lock core, dead bolt is retracted in the assembly case, and lock is promptly opened.

Among the figure: (1) lock body, (2) lock core, (3) L shaped pellet shot from a slingshot, pellet shot from a slingshot in the middle of (4), (5) cylindrical billiard, (8), (9) cylindrical billiard spring, (10) cylindrical billiard envelope), (11), (12) lock core cylindrical billiard hole, (13) L shaped pellet shot from a slingshot hole, (14) lock body cylindrical billiard hole, (15) key, (16) key balance tenon, (17) key, (18) L shaped pellet shot from a slingshot envelope, (19) handle, (20) lock core balance tenon, (21) lock core compensating groove, (22) bayonet lock, (23) tooth bar.

Referring to Fig. 1, Fig. 8, be provided with L shaped pellet shot from a slingshot hole (13) and cylindrical billiard hole (14) in the lock body (1), corresponding respectively L shaped pellet shot from a slingshot (3) and the cylindrical billiard (7) of being equipped with, cylindrical billiard hole (14) lining of cylindrical billiard (7) in lock core (2) is packed lock body (1) into; The marble spring (6) that matches with L shaped pellet shot from a slingshot hole is housed in the bending place of L shaped pellet shot from a slingshot (3) and seals (8) and be enclosed in the lock body (1) by pellet shot from a slingshot.Lock core (2) is provided with two row cylindrical billiard holes (11), (12), cylindrical billiard and marble spring (8), (9) all is housed in it, and is sealed by pellet shot from a slingshot envelope (10).Cylindrical billiard hole (11), (12) respectively with lock body (1) in L shaped pellet shot from a slingshot hole (3) and cylindrical billiard hole (7) to logical, in the through hole that lock core cylindrical billiard hole (11) and the L shaped pellet shot from a slingshot of lock body hole (13) are linked to be cylindrical billiard (5) and middle pellet shot from a slingshot (4) are housed, (4) one of middle pellets shot from a slingshot contact with cylindrical billiard (5), one contacts with L shaped pellet shot from a slingshot (3), one in lock core, one in lock body.Referring to Fig. 2, Fig. 6, Fig. 7, after key (17) inserts key (15), key bit forces L shaped pellet shot from a slingshot (3) outwards to move away from lock core, in lock body, abdicate the space for middle pellet shot from a slingshot (4), middle pellet shot from a slingshot (4) enters lock body because spring (8) effect is ejected lock core by cylindrical billiard (5), pellet shot from a slingshot (4) overlaps with the breakdown position with the contact surface of cylindrical billiard (5) in the middle of this moment, meanwhile, cylindrical billiard (7) is also pushed up to open-part by key, firmly pressing handle (19) makes lock core (2) move to depth, because of lock core (2) is connected with tooth bar (23), drive the interior gear mechanism of lock assembly by tooth bar (23), by the tooth bar on the gear mechanism drive dead bolt, dead bolt is retracted in the assembly case again, locks promptly opened.

Referring to Fig. 3, when cylindrical billiard (7) is pushed up to open-part by foreign matter, L shaped pellet shot from a slingshot (3) is also pushed up to the enable possition of drafting, but in the middle of pellet shot from a slingshot (4) because the effect of external force is stuck in open-part by the waist, still lock can not be opened.
