Abstract
The utility model relates to a locking head, belonging to the core part of locks, aiming at solving the problems of blade-shaped night locks such as complicated structure, difficult production and bad result of preventing technological unlocking. The external circle of the locking shaft 2 with a central hole has sidesteps. A locking blade slot 15 is arranged at a section of the external circle. An unlocking hole 14 is positioned on one side of the locking blade 4 and can do axial movement in the locking blade slot 15. The tail-cuff 7 is fixedly sleeved at one end of the locking shaft 2 and is used to fix the position of the poking strip 8. The end face of the lock ring 5 has a locking hole 18. The lock ring is sleeved on the external circle of the locking shaft 2. The locking head sleeve 11 is sleeved on the external circle of the lock ring 5 and is connected with the locking head cover 1. The utility model has the advantages of compact structure, simple processing and more difficult unlocking technology, which is mainly used for various mechanical locks.
Description
Technical field
The utility model relates to a kind of tapered end, especially can prevent technology unlocking.
Background technology
At present, the pellet shot from a slingshot class tapered end that generally uses can both in a few minutes, even be opened in a few second with the method for technology unlocking under keyless situation in the market.A kind of tool of exchanging work of drawing that the master key principle unblanks that uses is arranged, on a forked scale copper or steel wire, have can bi-directional movable the elasticity hook.This instrument can be opened multiple on the market at present cylinder lock effectively.General cylinder lock only needs with two steel wires, one sub two laybacks of lock core, give a revolving force, lock core is turned an angle, another root is drawn in the spoon groove, make the pellet shot from a slingshot retaining on the edge of tapered end lock hole, use the principle of master key, can unblank.
I in 200520050923.4 patents, whole tapered end processed complex, particularly tapered end seat difficult processing, tapered end processing cost height; Though, but still can draw by a side plane that has only unlocking port and dial in the difficulty of design jut in the both sides of locking plate with the increase technology unlocking, reach the purpose of technology unlocking, the effect of anti-technology unlocking is not satisfactory.
The purpose of this utility model provides a kind of tapered end.
The technical scheme that its technical problem that solves the utility model adopts is: lock shaft (2) cylindrical of band centre bore has step, one section cylindrical is provided with locking plate groove (15), locking plate (4) one sides have unlocking port (14) and can move axially in locking plate groove (15), tail cover (7) suit is fixed on an end and the fixing position of dialling bar (8) of lock shaft (2), the end face of lock ring (5) has last fore shaft (18), lock ring (5) is sleeved on lock shaft (2) cylindrical, and tapered end cover (11) is sleeved on lock ring (5) cylindrical and links to each other with tapered end cover (1).
Lock ring (5) is flanged pull and stretch cylindrical shell, and its bottom has interior circle, the circumference of interior circle that last fore shaft (18) is arranged.
There is the anti-moving tooth (9) of drawing of saw shape the adjacent both sides of unlocking port (14) of locking plate (4), and the adjacent both sides of last fore shaft (18) have stepped anti-drawing to dial step (10).
The beneficial effects of the utility model are, simplify the tapered end cover structure, and its lock ring and tail cover can adopt impact forming method to process, and lock ring has locking and be the dual-use function of locking plate location, compact conformation and processing simply.Especially the design of the adjacent both sides of the unlocking port of locking plate has the anti-moving tooth of drawing of saw shape, the adjacent both sides design of last fore shaft have stepped anti-draw dial step after, make the technical application person of unblanking be difficult to judge real unlocking port or go up the fore shaft position, prevent that the technology unlocking performance is more superior.

Among the figure: 1. tapered end cover, 2. lock shaft, 3. lean at the center, 4. locking plate, 5. lock ring, 6. spring, 7. tail cover, 8. group bar, the 9. anti-moving tooth of drawing, 10. anti-drawing dialled step, 11. lock tubes, 14. unlocking port, 15. locking plate grooves, fore shaft on 18..
The specific embodiment
By Fig. 1 to Figure 10 as can be known, tapered end cover 1 is a sheet, and keyhole is arranged, and lock shaft 2 has centre bore, and is cylindric and a step is arranged, and can insert central post 3.
A side has unlocking port 14 on the locking plate 4, and there is the anti-moving tooth 9 of drawing of saw shape locked groove 14 adjacent both sides.Locking plate 4 is contained in the locking plate groove 15 of lock shaft 2, and the other end of lock shaft 2 has spring eye, built-in spring 6, and locking plate 4 can move axially under the active force of spring.Tail overlaps 7 suits and is fixed on the right-hand member and the fixing bar 8 of dialling of lock shaft 2, promptly dials the cylindrical void of dialling that bar 8 passes tail cover 7.Tail cover 7 also entangles spring and group bar 8 simultaneously.Lock ring 5 is flanged pull and stretch cylindrical shell, and its bottom has interior circle, the circumference of interior circle that last fore shaft 18 is arranged.
When not inserting key, locking plate 4 is stuck in the last fore shaft 18 of lock ring 5 and can not rotates; After inserting key, the spoon bar promotes to have the locking plate 4 of unlocking port 14, makes the end face of the unlocking port 14 aligning lock rings 5 of locking plate 4, and screw key makes lock shaft 2 rotations, thereby reaches the purpose of locking and unblanking.
When the used instrument of technology unlocking was pushed fore shaft and last fore shaft aside at hook, its adjacent both sides had all that the saw shape is anti-draws moving tooth or stepped anti-drawing dialled step, make the technical application person of unblanking can't judge real unlocking port or go up the fore shaft position, reach the purpose of anti-technology unlocking.
