With reference to the accompanying drawings, stator body of label 1 expression, this stator body is made of the parallelepiped with a cylindrical center hole 2 in an illustrated embodiment.

Stator body 1 columniform rotor block 4 round axis 3 rotatably supports.Clearly, the shape of stator 1 and rotor 4 and layout can be to be different from any kind that illustrates by way of example purely in the accompanying drawings.Certain above-mentioned mode that is applicable to that also rotor 4 by stator 1 rotatably support.In addition, purely by way of example, accompanying drawing relates to such a case, and wherein, columniform rotor block 4 has side of a surperficial 1a who rests in stator 1 and by four lining 5 rotatably supports, these four linings 5 are installed on four connecting rods 6 free to rotately, and these four connecting rods 6 pass the through hole 7 of stator body 1 and be screwed onto on two

end plates

8,9 in their end, therefore,

end plate

8,9 is screwed onto on the stator 1 rigidly.The shape of the stator here and connecting rod 6 and

end plate

8,9 still provide in the mode of giving an example purely, because any other shape of stator and rotor and layout also are feasible.

Four rotating linings 5 contact with the cylindrical surface 4a of rotor 4, are therefore supporting rotor and are rotating with respect to stator 1 around axis 3.In addition, shown in example in, cylindrical rotor body 4 has that six central axial lines 3 around rotor 4 distribute and the cylindrical shape through hole 10 that separates of equal angles each other.Through hole 10 receivabilities be rigidly connected to one the dish 12 on and with cantilevered fashion from its corresponding bar 11 that stretches out.This dish 12 lean against stator 1 with the opposed end face of end face 1a on, and bar 11 passes the medium pore 2 of stator and be received within the hole 10 of rotor 4, so rotor 4, dish 12 and bar 11 form an independent rotor unit that is rotatably mounted around axis 3 with respect to stator.

Label

13,14,15,16 four guard plates of head that show one group of guard plate (other guard plate in Fig. 3 as seen), these guard plates are arranged in the plane perpendicular to the pivot center 3 of rotor 4, and are being supported by rotor unit, can be with respect to axis 3 along three direction X-X, Y-Y, Z-Z (Fig. 4) radially slides.More precisely, this

group guard plate

13,14,15,16 (certainly, this device can have these plates of any number) is arranged in the bar 11 in the hole 2 of stator 1.As Fig. 2, shown in 4, each

guard plate

13,14,15,16 has two side S, and these two side S are slidably along three direction X, and Y, one of Z are guided between opposed two pairs of bars 11.In addition, each above-mentioned plate has a preceding lock part, this lock part shown in example in constitute by two tooth T, it is suitable for being meshed with the groove 17 of the coupling that forms on the cylinderical surface in the hole 2 of stator 1, rotates with respect to stator so that prevent the rotor unit that is loaded with guard plate 13-16.In addition, in its front, each guard plate has a breach R, and it is suitable for being meshed with a respective rods 11, so that limiting plate is along radially outer terminal location.In opposite end, each guard plate has a breach V, and it is suitable for matching with a corresponding bar 11, so that an opposed terminal location of limiting plate, at this moment, the groove 17 of locking teeth T and stator breaks away from engagement, therefore, in this position, plate can make rotor 4 freely rotate in stator.At last, each guard plate 13-16 has a medium pore, and this medium pore has two opposed type bodies 19, this type body 19 be used for matching with two opposed type bodies 20 that activate key 21 (being also shown in Fig. 1).The live part of key 21 has three pairs of opposed airfoil-shaped portions 20 of separating of equal angles each other, they are used for matching with each guard plate 13-16 respectively, when inserting this lock with the key of box lunch regulation, the type body of key can make each guard plate return to the groove 17 out-of-gear positions of T of tooth at that time shown in Figure 4 and stator, so that rotor can freely rotate along with key 21.The live part of key 21 is received in the medium pore with respective cross section 22 of rotor block 4 and in the hole that also has respective cross section 23 of dish 12.In addition,

end plate

8 and 9 has

medium pore

24 and 25, and this medium pore has corresponding cross section, makes key to insert the rotor from a side and opposite side.When the live part of key inserts in the medium pore 22 of rotor, a tube reducing bar portion 26 that does not hinder rotor freely to rotate with respect to stator of key will be arranged in the

medium pore

24 and 25 of end plate.Key 21 also is provided with stopping element 27, and it is suitable for matching with the front of end plate 8, so that limit the suitable axial location of key in lock.

When key inserts rotor 4, if it be have a reservation shape and lock when being key for its regulation that designs, guard plate 13-16 will return to they and the out-of-gear position of stator, so can make the rotation of key pass to rotor.

As mentioned above, rotor certainly is connected with the driven member such as hitching post of house door or safe door by any mechanical transfer device, so as with described door locked in fastening position.

When key is withdrawn from from lock, guard plate no longer is retained on their resting position, thereby can freely return, each turns back to the position with the locked rotor of stator, in case rotor is correspondingly directed, when for example attempting to make rotor rotation after the key of non-regulation inserts in the lock, guard plate can turn back to this position by gravity.

As mentioned above, the shape of rotor and stator can be any being different from purely with any kind shown in the mode of example; Certainly this also is applicable to guard plate, and the mode that the number of guard plate, guard plate are being supported slidably by rotor and these plates are along its number radially and layout that is slidingly installed.

Clearly, though principle of the present invention can remain unchanged, without departing from the scope of the invention, the details of its structure and embodiment can with respect to describe by way of example purely and show very big variation arranged.
