Description
Technical field
The utility model relates to a kind of lockset, relates in particular to a kind of lock.
Background technology
Now the lockset of Shi Yonging comprises lock core and the stator that is provided with keyhole, and its utilizes the pellet shot from a slingshot be positioned at stator and the pellet shot from a slingshot of core to cooperate, the rotation of realization core or do not rotate.Because pellet shot from a slingshot along the axial straight line of core, adopts one to dial bar, stirs pellet shot from a slingshot up and down with the feel straight line, to realize easily unblanking, theftproof is relatively poor.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of rational in infrastructure, anti-good anti-theft lock end and the key thereof of performance of dialling.
The utility model is to realize like this, a kind of anti-theft lock end comprises lock core and the stator that is provided with keyhole, pellet shot from a slingshot and spring are contained in the pellet shot from a slingshot hole of lock core and stator, radially be provided with the protection badge at lock core with wide vertical direction of keyhole, the height of described protection badge equals lock core thickness and key thickness sum, on the protection badge pressure pearl is arranged, press the top of pearl that spring is arranged, protection badge and pressure pearl can radially move up and down along lock core; At the other end of keyhole, radially be provided with the insurance card pearl at lock core perpendicular to the wide face of keyhole, the height of insurance card pearl equals the wall thickness of lock core, and the insurance card pearl is provided with insurance and presses pearl, and insurance presses pearl to be provided with spring; Be provided with at stator and be parallel to axial gathering sill, on the movable bayonet lock projection is arranged, be equipped with spring between movable bayonet lock projection and gathering sill, it is the narrow down wide inclined-plane of that movable bayonet lock is positioned at the end face of pressing the pearl top, movable bayonet lock is under the effect of promotion of pressing pearl and spring, movable bayonet lock can be along translation in the gathering sill, and stator cover is sealed pellet shot from a slingshot in the stator, spring and movable bayonet lock.
The centre of the utility model key is provided with the shutter hole clipping; the width of described shutter hole clipping slightly is wider than the protection badge; the length of shutter hole clipping is more than 2.5 times of shutter card thickness; the described card pearl indenture that is provided with on the key; card pearl indenture and insurance card pearl is suitable, is equipped with the hoodle indenture at the periphery and the positive and negative of key.
The utility model is provided with the protection badge; when dialling bar insertion keyhole; withstood the protection badge; the protection badge presses pearl that movable bayonet lock is pushed away to the right between lock core and stator body, is pressed in insurance and presses on the pearl; dial bar and dial motionless insurance card pearl; insurance presses pearl between lock core and stator body, dials bar like this and can not open tapered end of the present utility model at all, has realized antitheft effect.
Description of drawings
Fig. 1 is the structural representation of the utility model tapered end;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the B-B sectional view of Fig. 1;
Fig. 4 is Key structure figure of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments explanation the utility model.
As Fig. 1, shown in Figure 2, a kind of anti-theft lock end comprises the lock core 1 that is provided with a rectangle keyhole, stator body 2, stator cover 3, pellet shot from a slingshot and pellet shot from a slingshot spring (identical) in the pellet shot from a slingshot hole of lock core and stator with common cylinder lock, radially be provided with protection badge 7 at lock core 1 with 6 wide vertical direction of keyhole, the height of described protection badge 7 equals lock core 1 thickness and adds keyhole 6 thickness sums, on the protection badge 7 pearl 8 of pressure is arranged, press the top of pearl 8 that spring 9 is arranged, protection badge 7 and pressure pearl 8 can move up and down along wide vertical direction of lock core 1 keyhole, the other end at keyhole 6, be provided with insurance card pearl 10 in wide vertical direction of lock core keyhole, insurance card pearl 10 is provided with insurance and presses pearl 11, insurance presses pearl 11 to be provided with spring 12, insurance card pearl 10, insurance presses pearl 11 to move up and down along wide vertical direction of lock core 1 keyhole; As shown in Figure 3, be provided with gathering sill 13 on stator, movable bayonet lock 14 has a projection, and movable bayonet lock 14 projectioies and 13 of gathering sills are equipped with spring 15; It is the narrow down wide inclined-plane of that movable bayonet lock is positioned at the end face of pressing pearl 8 tops, movable bayonet lock (14) is under the effect of promotion of pressing pearl 8 and spring 15, movable bayonet lock is pressing the end face above the pearl 8 to be wide inclined-plane narrow down, movable bayonet lock 14 can be along gathering sill 13 translations under promotion of pressing pearl 8 and spring 15 effects.Stator cover is sealed stator inner spring, pellet shot from a slingshot, movable bayonet lock.
