Abstract
The utility model discloses a cylinder lock head with high security, which is a locking head component in a spring lock. The cylinder lock head with high security is characterized in that a ladder shape cylinder core bar is firmly fixed in a lock core hole, which makes a cylindrical key insert in the void. Multiple rows of snap head strings are arranged on the cylinder wall of a lock core. Corresponding string recesses with different depths are arranged on a cylindrical key. Each row is range in radial shape along the axial line of the lock core. The utility model raises the confidentiality of the locking head, and makes key copying difficulty. The utility model has the advantages of simple fabrication, easy accuracy guaranteeing and the good interchange ability of component parts.
Description
The utility model belongs to the tapered end parts in a kind of cylinder lock.
Ball lock head parts used in everyday generally adopt the single-row billiard structure, and this lock is because simple in structure, thereby with low cost.Make the tooth of key spend finite capacity but its critical defect is a single-row billiard, the shape of key is similar in addition, so its confidentiality extreme difference is easy to be made tapered end lose effectiveness by imitated.
CN90226236.X discloses a kind of " arranging cylinder lock " more, its lock core endoporus and key adopt just polygon prism-shaped and many row's pellets shot from a slingshot are arranged, two isometric close the door pellet shot from a slingshot and several pellets shot from a slingshot of partly closing the door are arranged in the lock tube pipe simultaneously, therefore the confidentiality of lock is strengthened greatly, and key also is difficult for by imitated.But this structure makes the processing technology of tapered end and key complicated, and is very high to the element precision requirement, the interchangeability extreme difference during the part assembling, thereby be difficult to implement.
The purpose of this utility model overcomes the deficiency of above-mentioned prior art for society provides a kind of, simple ball lock head is processed and assembled to the confidentiality height.
The reliable following technical proposals of this purpose reaches:
Identical with CN90226236.X, it comprises the key of lock tube pipe, lock core, locking bar, cover tubular and is contained in one in the lock core arranges above pellet shot from a slingshot, and wherein lock core places among the core hole of lock tube pipe; Core bar places among the core hole of lock core and is fixed together; The key of cover tubular can insert among the space between core bar and lock core, and be shaped on the key with lock core in the corresponding pellet shot from a slingshot recess of pellet shot from a slingshot.
Both are at different places: lock core is the cylindrical sleeve tubular, is shaped on the above pellet shot from a slingshot hole of a row on it, and each arranges the pellet shot from a slingshot hole serves as that axle is radial arrangement with the lock core axis; The head of packing in each pellet shot from a slingshot hole is hemispheric pellet shot from a slingshot; Key is the cylindrical sleeve tubular, and its external diameter is identical with the core hole internal diameter of lock core; Core bar is the ladder cylinder, and one section wherein thick external diameter is identical with the core hole internal diameter of lock core, and one section thin external diameter is identical with the internal diameter in key core hole.
This tapered end has following advantage:
1, because the structure of many row's pellets shot from a slingshot improves the confidentiality of lock greatly;
2, because key is cylindric, and be shaped on the different pellet shot from a slingshot recess of many row's depths, make imitated person be difficult to achieve one's goal;
3, because major part is cylinder or cylindric, thereby make processing technology simple, precision guarantees that easily part assembling interchangeability is good, so this tapered end is implemented easily and applied, becomes the regeneration product of common spring tapered end.
Below by accompanying drawing and most preferred embodiment the technical program is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the lock core structure schematic diagram.
Fig. 3 is the core bar structure schematic diagram.
Fig. 4 is the lateral view of Fig. 3.
Among the figure: key (1); Key main body (11); Lock tube pipe (2); Tapered end encloses (21) again; Pellet shot from a slingshot sprue (31); Marble spring (32); Tack pellet shot from a slingshot (33); Hemispherical head pellet shot from a slingshot (34); Lock core (4); Pellet shot from a slingshot hole (41); Pin-and-hole (42); Circlip groove (43); Core bar (5); Pin-and-hole (51); Crank-guide way (52); Locking back-up ring (6); Lock core connecting rod (7); Pin (8).
Referring to Fig. 1~Fig. 4.Lock core (4) is the cylindrical sleeve tubular, is shaped on 4 row pellet shot from a slingshot holes (41) on its barrel altogether, and this four rows pellet shot from a slingshot hole is the axial symmetry radial arrangement with its axle center.Core bar (5) is the ladder cylinder, and its one section thick external diameter equals the core hole internal diameter of lock core (4), and its one section thin external diameter equals the core hole internal diameter of key main body (11).After in the core hole of core bar (5) insertion lock core (4), insert pin-and-hole (42), (51) with pin (8), so, core bar and lock core are connected as a single entity.Then, the hemispherical head pellet shot from a slingshot (34) of in the pellet shot from a slingshot hole (41) of lock core, packing into.The hemispherical head pellet shot from a slingshot is an oblate cylinder, and its head has a hemispherical, and its size is advisable can insert just in the upward made pellet shot from a slingshot recess of key main body (11).Shoot the period of the day from 11 p.m. to 1 a.m, should be undertaken by on the key nest number (tooth number) and angular coding requirement.Then lock core and core bar are packed into together in the core hole of lock tube pipe (2).By respective coding in the pellet shot from a slingshot hole of lock tube pipe, pack into tack pellet shot from a slingshot (33) and marble spring (32), use pellet shot from a slingshot sprue (31) to shut the pellet shot from a slingshot hole at last again.After inserting lock core connecting rod in the core bar groove (52), snap in the circlip groove (43) of lock core, lock core connecting rod and lock core can be linked up with locking back-up ring (6).At this moment the cylindrical sleeve shape space that the key that matches (1) can insert between core bar and the lock core is opened or is closed.Key (1) comprises a key main body (1) and key handle.Main body (1) is a cylindrical sleeve, is shaped on four row's pellet shot from a slingshot recesses on its barrel, and recess deep mixed is equivalent to the tartar of normal key, and its tooth number is corresponding with lock core marble with angular coding.
The external surface of core bar (5) and hemispherical head pellet shot from a slingshot (34) is carried out nitrogenize or other cure process will make the tapered end life-span prolong greatly, and can make sled dial difficulty more.
