Fig. 3 view is similar to Fig. 2, is presented at rotor axial and inserts before the stator, and back-moving spring is located in the axial end portion of rotor;
Fig. 4 to Fig. 9 represents successively, and three elements shown in Fig. 2 and Fig. 3 are in the assembling process of determining and the relevant position when the use of lock.
Can see that from Fig. 1 and Fig. 2 the main composition of the lock 10-that the present invention relates to partly is a stator that is the cylindrical sleeves shape 14, a rotor 12 and a back-moving spring 16.
The main composition of rotor 12 partly is a cylinder 24, and cylinder 24 axially inserts chamber 14 and rotates in its sleeve.
The cylinder 24 of rotor 12 has a head 26, be used for injecting the key (not shown) specially, the displacement of key control sheet metal group 28, sheet metal group 28 is contained in the line of rabbet joint 30 and the line of rabbet joint 32 by volume, the line of rabbet joint 30 is on rotor 12, and the line of rabbet joint 32 is on the annular post jamb of stator 14.
The radial end face 34 of rotor 12 1 ends will be accommodated in the inside of stator 14, and its central prolongation is circular center pillar 36, and the axis of center pillar 36 is on axis X-X that rotor 12 relative stator 14 are rotated.
This center pillar is used for admitting the main body 38 of back-moving spring 16, and back-moving spring 16 is coil springs.
From Fig. 1 and Fig. 2 as seen, the main composition of projection 42 partly is a projection body 44, and projection body 44 is with respect to the external cylindrical surface of the cylinder 24 of rotor 12 radial disbalance outwardly, and it axially stretches out from end sagittal plane 34.
When locating on center pillar 36, as shown in Figure 3, the setting of back-moving spring 16 is the drive side 50A and the 50B of the main body 44 that the radially elbow 40A of its end, 40B flexibly clamp drive lugs 42.
As can be seen from Fig. 3, rotor 12 and back-moving spring 16 are fitted together the formation composite member, and this composite member also comprises sheet metal 28, and composite member can be along the axis of orientation of arrow I among Fig. 3 in the cylindrical hole 18 that inserts stator 14.
For this reason, and in order to allow axially to insert elbow 40A, the 40B of drive lugs 42 and spring 16, individual axial groove 52 is arranged on the inwall of cylindrical hole 18, its inlet is positioned at the openend 20 in hole 18 and leads to radially bottom surface 22, end.
Especially can see that axial groove 52 leads to annular road junction 54 from Fig. 2, the latter forms on the cylindrical wall 56 of sleeve 14.
Extend on semicircle at annular road junction 54, and two block face 58A and 58B limit its two ends.
Two end face 58A and 58B also limit the angle stroke of rotor 12 with respect to stator 14, because the intervention of back-moving spring 16 respective end portions elbows, drive side 50A contacts with 58B with the end face 58A at annular road junction 54 in turn with 50B.
Especially can see from Fig. 2 that road junction 54 limits the annular radial edge of stators 14 cylindrical wall ends, it is divided into two position 60A and 60B, axially staggers mutually, and is separated by retaining 62.
Retaining 62 centre position from end ring edge 60A, 60B are that the intermediate angle position at road junction 54 is axially outstanding.
