Abstract
The utility model relates to a marble lock and arranges a rotating barrel between a lock core and a lock head. The rotating barrel, the lock core and the lock head are connected into integration through a pin. One side originally provided with a row of marble holes of the outer wall of the lock head is newly provided with a row of marble holes with the same distance being parallel with the original row of marble holes. Marbles and springs are arranged in the marble holes. The front end of the new row of marble holes has one less hole than the original row of marble holes. A reset spring is arranged between the back end surfaces corresponding to the rotating barrel of the bottom part of the central hole of the lock head. The back end surface of the lock core pushes on the inner step of the through hole of the back end of the rotating barrel.
Description
The utility model relates to a kind of cylinder lock.
Existing cylinder lock all has only single pellet shot from a slingshot system, as long as key is identical in the profile of tooth at place, pellet shot from a slingshot hole, just lock can be opened, and this just the phenomenon that a key can be driven many locks occurs inevitably, and theftproof performance is poor, is opened easily.
The purpose of this utility model is exactly in order to address the above problem, and provides a kind of theftproof performance good two pellet shot from a slingshot system safety lock.
Technical solution of the present utility model:
A kind of pair of pellet shot from a slingshot system safety lock, it includes tapered end 1, lock core 2 and dead bolt 3, it is characterized in that outside lock core 2, being with turning barrel 4, it is between lock core 2 and tapered end 1, and the position in turning barrel 4 corresponding lock cores 2 one row's pellet shot from a slingshot holes also has the pellet shot from a slingshot hole, and be placed with pellet shot from a slingshot, turning barrel 4, tapered end 1, lock core 2 is connected as a single entity by pin 5, side in the original row's pellet shot from a slingshot hole 6 of tapered end 1 outer wall is newly opened a pellet shot from a slingshot hole 7 that row is parallel with it and spacing is identical with it in addition, tapered end two row's pellet shot from a slingshot holes 6, be equipped with pellet shot from a slingshot and spring in 7, and newly open the front end in row's pellet shot from a slingshot hole 7 and lack one than original row's pellet shot from a slingshot hole 6, between the rear end face of corresponding turning barrel 4 at the bottom of tapered end 1 centre bore, be provided with back-moving spring 8, it is in pressured state all the time, and the rear end face of lock core 2 is against on the interior step of turning barrel 4 rear end through holes.
The utility model adopts two cover pellet shot from a slingshot systems, has maximally utilised the profile of tooth of a key, more can make key have uniqueness, prevents that effectively the robber from unblanking with instigateeing pin or master key, and theftproof performance improves greatly.
Fig. 1 is the cross-sectional view that the utility model is in readiness;
Fig. 2 is the cross-sectional view that the utility model is in opening;
Fig. 3 is the utility model turning barrel structural representation;
Fig. 4 is the A-A sectional drawing of Fig. 3;

Fig. 6 is the B-B sectional drawing of Fig. 5;
Fig. 7 is a lock head structure sectional drawing of the present utility model;
Fig. 8 is the lateral view of Fig. 7.
When the utility model uses such as Fig. 1, when key 9 inserts, at first making pellet shot from a slingshot hole and tapered end 1 on lock core 2 and the turning barrel 4 thereof newly open row's pellet shot from a slingshot hole 7 aligns, this is newly opened pellet shot from a slingshot hole 7 and preferably misplace on the outer round surface of lock body 1 with former row's pellet shot from a slingshot holes 6 and 90 spend, and the distance of a d of they each corresponding pellet shot from a slingshot hole phase mutual deviations, as Fig. 7,8, lack one owing to newly open the front end in row's pellet shot from a slingshot hole 7, can not be when this just makes key 9 be inserted into this place with the pellet shot from a slingshot a in lock core 2 and turning barrel 4 front ends

3Mutually tapered end 1 and turning barrel 4 are blocked and become one, make lock core 2 the same with common lock core operating principle simultaneously, lock core 2 can rotate arbitrarily in turning barrel 4, and to finish the effect unblanked, as Fig. 2, theftproof performance increases greatly.
This product is far better with regard to the also more common cylinder lock of its theftproof performance (nondestructive theftproof), this product is the design of tapered end, so can be widely used in various other locks, as: padlock, safe-guard door lock, bicycle lock, motor vehicle lock, soft lock etc.
