Abstract

The utility model discloses a precession type cylinder lock with double sleeves, belonging to the field of construction, which comprises an inner and an outer lock cores A and B, a lock stator C, a moving block D, a rotating plate E, a key F, a restoring spring (29), (30), etc. An inclined wedge body (27) on the moving block D and an inclined wedge (18) on the outer lock core B are mutually acted, and an entering guideway slot (23) is arranged on a hoodle in the inner lock core A, so unlock can be achieved. In addition, to the whole locking head, because the key F is converted into double sleeves namely the variation of the F is turned over myriad times, the relative repeatability of the whole locking head is decreased. The utility model has the advantages of safety and convenient operation. The utility model can be used for anti-theft devices such as institutions, enterprises, doors for civil use, etc.

Description

Double-sleeve lock

The utility model belongs to building field.

At present, people's lock used in everyday mostly is traditional single lock core structure greatly, its lock core has only 5 hoodle mechanisms, because inevitable fabrication error, make lock core just rotatable when key does not also insert, just can replace key like this as with two iron wires etc., one hoodle be provoked, one as the arm of force rotation can unblank.

The purpose of this utility model is to be to design the two sleeve locks of a kind of a kind of screw type safe and reliable, rational in infrastructure, easy to use.

The purpose of this utility model is achieved in that

The two sleeve locks of a kind of screw type, it comprises back-moving spring (29), (30), jump ring (36), it also includes,

Outer lock core B, be that to have small round bar (16) and thickness on that have a lockhole (34) and hoodle hole (33) cylinder be 1 projection (17), have round shrinkage pool (14) on the projection (17), (15) and fan type breach, wherein one side is wedge body (18);

Internal cylinder A, one has cylinder (22), (20), and square column (21), the lock core body of groove (19) has lockhole (35) and 5 hoodle holes (24) and guide-track groove (23) in the lock core body;

Tapered end stator C, one has the cylinder of circular hole, and circular hole half one has groove (13), and the degree of depth is 1/3 of internal cylinder B upper protruding block (a 17) thickness;

Movable block D, one nahlock with fan-shaped wedge body (27), interior opening square hole (25), the size of square hole (25) is corresponding with square column (21), and wedge body (27) one sides have groove (26), wedge body (27) thickness is 1/2, and is corresponding with the wedge dignity body (18) of outer lock core B;

Swivel plate E, on have circular hole (28) and bottom surface shrinkage pool (32) and the plug-in unit that is connected dead bolt (31);

Key F, on two keys (a.b) are arranged, link to each other by hinge (10), the width of bloom mouthful (9) of key (a.b) is projection among the outer lock core B (a 17) thickness 11/2, key (a.b) has two keep to the side (11), (12), two limits at interval 1/21.

Below in conjunction with drawings and Examples the utility model is further specified,

Fig. 1 is the utility model structural representation

A is an internal cylinder among the figure, and B is an outer lock core, and C is the tapered end stator, and D is a movable block, and E is a swivel plate, and 28 is circular hole, and 29,30 is back-moving spring, and 31 for connecting the plug-in unit of dead bolt, and 32 is shrinkage pool.

Fig. 2 is the utility model elevation

1,2,3,5,6 hoodles among the figure, 4,7 is spring, and F is a key, and 23 is guide-track groove.

Fig. 3 is the schematic diagram of key F in the utility model

A.b is two keys among the figure, and 8 is tooth, and 9 are the mouth of blooming, and 10 is hinge, and 11,12 for keeping to the side,

Fig. 4 is the schematic diagram of tapered end stator C in the utility model

13 is groove among the figure,

Fig. 5 is the schematic diagram of outer lock core B in the utility model

14,15 are the circle shrinkage pool among the figure, and 16 is round bar, and 17 is projection, and 18 is the wedge body, and 33 is the hoodle hole, and 34 is lockhole,

Fig. 6 is the schematic diagram of internal cylinder A in the utility model

19 is groove among the figure, and 20,22 is cylinder, and 21 is square column, and 23 is guide-track groove, and 24 is the hoodle hole, and 35 is lockhole,

Fig. 7 is the schematic diagram of movable block D in the utility model

25 is square hole among the figure, and 26 is groove, and 27 is the wedge body.

During use, the a.b of key F is entered lock core respectively, the lockhole of A.B (35), (34), tooth on the a.b (8), (9) difference jack-up hoodle (1), (5), hoodle 1～6 is all on board, at this moment, keeping to the side on the key F (11) withstood on the outer lock core B, outer lock core B is pushed into 1/21, keep to the side (12) push up the locking sub-C on, internal cylinder A because the propelling of outer lock core B and the wedge body (18) on the external lock B and movable block D go up that wedge body (27) interacts and internal cylinder A upward the effect of hoodle hole (24) and hoodle (2) enter guide-track groove (23) and quilt to anticlockwise, simultaneously because the effect of outer lock core B projection (17) and groove (13), make round bar (16) on the outer lock core B enter circular hole (28) on the swivel plate E, make projection (17) the release lock stator C upper groove (13) on the outer lock core B, hoodle (2) is misplaced, also because when A changes, round bar (16) is done concentric with circular hole (28) then is not had influence, round bar (20), (16) respectively in circular hole (28), back-moving spring (29), (30) be compressed, key F hinge 10 act as a plane, outer lock core A in can driving, B rotates simultaneously, driven rotary plate E, thus reach the purpose of unblanking.

The two sleeves of screw type are locked in when unblanking, must make outer lock core B advance 1/21 earlier, and then drive internal cylinder A to anticlockwise, and the not hoodle (2) only that stops that lock core B advances, (3), (6), and also have the effect and the projection (17) of wedge body (27) on the movable block D and the wedge body (18) on the outer lock core B upper protruding block (17) and lock the effect of sub-C upper groove (13), make outer lock core B that a bit left-right rotation can not be arranged easily, even eliminated wedge body (27), (18) effect, be that A changes earlier, but, hoodle (2) among the internal cylinder A make hoodle (3) not in place owing to can't dropping on the edge, outside of going up that has reached A in the guide-track groove (23), it is the external surface of B and stoped the propelling of outer lock core B, same hoodle (6) does not put in place yet and can make hoodle (5) not in place yet, outer lock core B can't advance, so be difficult to open.
