Description

Lock plate type core new construction

The utility model relates to a kind of lock of the cylinder lock that has board-like tumbler, particularly a kind of single arrangement.

The lock plate type lock core structure that tradition is common, as Fig. 1,2, the single file of its vertical core body A axis warp-wise wears most sheet slotted eye A1, all insert a lock board B in each sheet slotted eye A1, and outwards eject by a spring B 1, make the latch piece B2 of each lock board B spring B 1 side, dislocation is gone into lock barrel sleeve C correspondence and is dug the latch hole C1 that establishes, and side also is connected with another latch piece B3 in addition.Each is locked board B center and wears a slotted hole B4, inwardly extend a pointed unlock chip B5 at the slotted hole B4 of latch piece B3 side lateral margin, make the unlock chip B5 that respectively locks board B make different height, to change the different key D that unblanks, on core body A axis, be provided with a pancake keyhole E, respectively establish a sliver E2 on the two vertical wall E1 of keyhole E, correctly insert and aim at the unlock chip B5 that respectively locks board B with the guiding key D recessed D1 that respectively unblanks, unlock chip B5 with the identical respective heights of different depth, make the latch piece B2 that respectively locks board B shift out lock barrel sleeve latch hole C1 fully and in the retraction core body A, can open locked object spare by revolving plug body A interlock lock bolt.Tradition lock plate type lockset just relies on single file respectively to lock the unlock chip B5 of board, change the unlatching of lockset with differing heights, and the opening or lock motion of unlock chip B5 or latch piece B, all on same actuating wire, thereby, be easy to be stretched into interior pressure of keyhole E and dial, to feel the high and low position of each lock board B unlock chip B5 by burglar's tool using (as steel wire or steel disc), just can pry open lockset soon, so that lose the function of this lockset.For this reason, the dealer improves the core of the staggered breech lock that proposes a kind of lock plate type lockset, as Fig. 3, wears the sheet slotted eye F1 of predetermined number in vertical its radial axis of core body F, each adjacent sheet slotted eye F1 is to be staggered, to its objective is the locking maintainability that improves lockset.The more above-mentioned traditional locks of this structure is arranged equidistantly side by side, and structure is not subject to burglar's unlatching, but the lock board is only to be staggered altogether, can only prolong sled and steal uncaging time, though mainly being the lock board, it is not arranged on the same action axis of keyhole, but still be staggered on the keyhole inner vertical shaft line, the burglar still can utilize two tools stir one by one the lock board be concordant state, can reach the purpose of unblanking, thus the forfeiture anti-theft feature.

The purpose of this utility model is to improve a kind of lock plate type core new construction, and it can make the lock board open with instrument for the burglar, reaches complete anti-theft feature.

Utility model is achieved in that vertical its radial axis of core body wears the sheet slotted eye of predetermined number, and each adjacent sheet slotted eye is with equidistant arrangement, digs in its side that parallels to the axis and establishes a microscler breech lock slotted eye, digs on axis and establishes a convex keyhole; Lock barrel sleeve fit and limit are held the rotatable core body in ground, and its inner hole surface is respectively dug the microscler breech lock slotted eye rotation open and close two fixed point orientation of core body and established locator card door bolt groove; The lock board of predetermined number, its V-shaped body in bottom, dig and establish a groove at the center upper portion place, set a spring in the groove, a latch hole is established in the side, is being unlocking condition just corresponding to the microscler breech lock slotted eye of core body horizontal axis, and the lock board is sliding respectively to be put in lock core sliced trench hole; Rectangular latch lever one side of card door bolt is provided with several equidistantly and corresponding to the clamping bolt column of lock board side latch hole, and two ends respectively are provided with a spring, to be embedded in the microscler breech lock slotted eye of core body horizontal axis, rectangular latch lever opposite side is horizontal v-shaped object, and the locator card that holds on lock barrel sleeve endoporus hole wall is fastened with a bolt or latch in the groove; The corresponding core body of key convex keyhole is convex shape, and is provided with shrinkage pool to celebrating respectively to lock the position of board bottom chevron shaped body and highly dig;

The lock board of the utility model mat predetermined number is inserted arrangement with the sheet slotted eye of equidistantly vertical core body axis predetermined number, form its side card door bolt or unlatching core body and sleeve state that be hidden in the card door bolt that parallels to the axis, thereby, the lock board can't be opened with instrument for the burglar, can reach anti-theft feature fully, and its structural member simplifies, assembles fast and convenient, can reduce cost.
