Abstract
A shaped cylinder for cylinder lock features that it has a step to form a smaller-diameter head at external end and the length of said smaller-diameter head is greater than the distance between the inner hole of lock casing and lock core but less than that of moving key to inner hole of bolt. When the cock is illegally unlocked, the smaller-diameter head is jammed, preventing the illegal unlocking.
Description
Technical field
The present invention relates to a kind of antitheft sylinder field, particularly a kind of used for spring lock abnormity pellet shot from a slingshot.
Background technology
Existing special-shaped pellet shot from a slingshot, because structural problem, be difficult to prevent technical opening, main cause is that the diameter of special-shaped pellet shot from a slingshot is identical with other billiards diameter, when running into technical opening, because diameter is identical, so lock inboard aperture and lock apertura lateralis relative position have no change substantially, so can being resembled, special-shaped pellet shot from a slingshot is pulled out the locking bolt endoporus the common spring, a pellet shot from a slingshot that had both just stayed at last is special-shaped pellet shot from a slingshot, also be easy to be pulled out the locking bolt endoporus, form the technology release.
Summary of the invention
The present invention is realized by following scheme:
The same with common cylinder lock, constitute by core, lock tube, marble pressuring spring etc., but special-shaped pellet shot from a slingshot is made into the pellet shot from a slingshot of many diameters, the special-shaped pellet shot from a slingshot head of pellet shot from a slingshot end in the inner part, its diameter is less than the diameter of common spring.The diameter of other parts is less than the diameter of special-shaped pellet shot from a slingshot head.Like this when cylinder lock runs into the technology release, because the diameter of special-shaped pellet shot from a slingshot is less than common spring, the abnormity pellet shot from a slingshot can not be pulled out the locking bolt endoporus during beginning, have only after outside pellet shot from a slingshot all is pulled out the locking bolt endoporus, the abnormity pellet shot from a slingshot just can be choked, but what choke is the special-shaped pellet shot from a slingshot post part of special-shaped pellet shot from a slingshot, because its diameter is smaller, so can the center displacement put into effect between apertura lateralis and lock endoporus, the special-shaped pellet shot from a slingshot head of adding close inboard pellet shot from a slingshot is bigger than special-shaped pellet shot from a slingshot post, forms projection, just in time special-shaped pellet shot from a slingshot head is stuck in the interior along on the platform of apertura lateralis, so this lock can not opened at last.
Description of drawings
Fig. 1 is the schematic diagram of the present invention abnormity pellet shot from a slingshot when not being unlocked in the cross lock;
Fig. 2 is the schematic diagram of the present invention abnormity pellet shot from a slingshot when running into the technology release in the cross lock.
1 special-shaped pellet shot from a slingshot head, 2 special-shaped pellet shot from a slingshot posts, 3 lock tubes, 4 lock cores, 5 inboard pellets shot from a slingshot, 6 outside pellets shot from a slingshot, 7 stage clips, 8 apertura lateralises, 9 locking bolt endoporus, 10 lock core holes, 11 special-shaped pellets shot from a slingshot among the figure.
The specific embodiment
Now the invention will be further described with reference to the accompanying drawings.
As shown in Figure 1, key inserts the lock core normal release from lock core hole 10.Special-shaped pellet shot from a slingshot 11 of the present invention mainly is made up of two parts; Abnormity pellet shot from a slingshot head 1 and special-shaped pellet shot from a slingshot post 2 constitute.The diameter of abnormity pellet shot from a slingshot head 1 is more smaller than common spring diameter, as long as guarantee when common spring is choked by apertura lateralis 8 and locking bolt endoporus 9 during in the technology release, special-shaped pellet shot from a slingshot 11 can be in lockhole free activity just passable.The diameter of abnormity pellet shot from a slingshot post 2 is less than the diameter of special-shaped pellet shot from a slingshot head 1, just makes special-shaped pellet shot from a slingshot 11 at the platform that do not bring out near inboard pellet shot from a slingshot 5.The length of abnormity pellet shot from a slingshot head 1 will guarantee bigger than the gap of lock tube 3 endoporus and lock core 4, and it is little to enter the length of locking bolt endoporus 9 when not inserting key than special-shaped pellet shot from a slingshot 11.Since special-shaped pellet shot from a slingshot 11 in lock some, when normally unblanking, common spring can guarantee that apertura lateralis 8 and locking bolt endoporus 9 are concentric, special-shaped pellet shot from a slingshot 11 can not influence normally unblanks.
As shown in Figure 2, because the diameter of special-shaped pellet shot from a slingshot 11 is littler than common spring, thus when running into the technology release, can not choked, can be up and down in lockhole, after outside pellet shot from a slingshot 6 is extruded locking bolt endoporus 9, abnormity pellet shot from a slingshot post 2 is choked by locking bolt endoporus 9 and apertura lateralis 8, because special-shaped pellet shot from a slingshot post 2 diameters are less, locking bolt endoporus 9 can shift out platform by centre bit with apertura lateralis 8, in this case, the appearance of apertura lateralis 8 can stop special-shaped pellet shot from a slingshot head 1 to enter apertura lateralis 8, and therefore, this lock can be by technical opening.
The special-shaped pellet shot from a slingshot 11 that the present invention relates to is applicable to all cylinder locks (as a letter lock, cross lock etc.).
