Since the cam 13 is sleeved on the rotating rod 10 and can rotate along with the rotating rod 10, when the cam 13 rotates, the locking piece 14 can slide relative to the cam 13 along the outer circumferential surface of the cam 13, so that the locking piece 14 cannot interfere with the normal rotation of the rotating rod 10. When the turning lever 10 is rotated by a preset angle, the concave portion 131 is just aligned with the locking piece 14, at this time, the locking piece 14 can drop into the concave portion 131, so that the locking piece 14 completely exits the limiting hole 170, at this time, the locking piece 14 releases the lock between the lock cylinder 12 and the lock cylinder housing 17. The scheme realizes the locking between the lock cylinder 12 and the lock cylinder shell 17 by using a simple structure, the locking mechanism 100 and the rotating rod 10 form linkage, the locking between the lock cylinder 12 and the lock cylinder shell 17 can be released only on the premise that the rotating rod 10 is unlocked, the safety is good, and the practical application is convenient.
The shape of the lock member 14 is not particularly limited as long as the requirement that the normal rotation of the cam 13 is not affected in shape and the movement can be satisfied in size is satisfied. Preferably, the locking piece 14 is spherical, and rolling friction is formed between the spherical locking piece 14 and the cam 13, so that friction force between the locking piece 14 and the cam 13 can be very small, and normal movement of the lock cylinder 1 is prevented from being influenced by excessive friction. Of course, the locking member 14 may have other shapes such as a column shape.
The cam 13 and the rotating rod 10 are linked, and the linkage can be realized by directly fixedly connecting the cam 13 to the rotating rod 10, or can be realized by connecting the cam 13 and the rotating rod 10 by using a connecting piece such as a bolt. In the preferred embodiment provided in this example, the rotary rod 10 comprises a first rod section 106 and a second rod section 107, wherein the blade 11 is sleeved on the first rod section 106, and the cam 13 is sleeved on the second rod section 107, so that a larger distance is reserved between the cam 13 and the blade 11, and mutual interference between the cam 13 and the blade 11 is prevented. The second pole segment 107 is non-circular in cross-section, such as polygonal, elliptical, etc. Correspondingly, the cam 13 is provided with a second mounting hole 133, the shape of the second mounting hole 133 being adapted to the second pole segment 107, so that the cam 13 can be slipped over the second pole segment 107. The fit between the non-circular structures can very conveniently realize the function of circumferentially fixing the cam 13 and the second rod section 107, and the scheme only needs to sleeve the cam 13 on the second rod section 107 during production, and other process steps are not needed, so that the production is very convenient.
Since the lock cylinder 12 and the cylinder housing 17 can only be unlocked if the recess 131 is aligned with the locking element 14, means for providing a limit for the cam 13 in the circumferential direction are also provided. Specifically, referring to fig. 8, the vane 11 is provided with a positioning post 1131 extending toward the cam 13, and in the case of having a plurality of vanes 11, one vane 11 closest to the cam 13 may be selected to be provided with the positioning post 1131, for example, the present embodiment selects the third vane 113 to be provided with the positioning post 1131. Correspondingly, a positioning lug 132 is arranged on the outer peripheral surface of the cam 13, and when the cam 13 rotates to the concave part 131 to align with the locking piece 14, the positioning lug 132 just abuts against the positioning column 1131, so that the cam 13 cannot continue rotating in the circumferential direction, and the concave part 131 is ensured to accurately align with the locking piece 14, so that the locking piece 14 can fall into the concave part 131.
The lock core 1 also comprises a reset mechanism for driving the components to reset. Specifically, the reset mechanism comprises a first reset mechanism and a second reset mechanism, wherein the first reset mechanism is used for driving the rotating rod 10 to reset, and the cam 13 is associated when the rotating rod 10 resets. The second reset mechanism is used for driving the blade 11 to reset. The lock cylinder 12 is provided with a first installation groove 121 for installing a first reset mechanism and a second installation groove 122 for installing a second reset mechanism, respectively, and a third installation groove 123 is provided between the first installation groove 121 and the second installation groove 122 to block the first installation groove 121 and the second installation groove 122.

The reset disc 16 has a third mounting hole 163, the shape of the third mounting hole 163 being adapted to the second pole segment 107, so that the cooperation between the reset disc 16 and the second pole segment 107 can be achieved by using the method of cooperation of the cam 13 with the second pole segment 107 in the above-described solution. One end of the reset torsion spring 161 is connected with the inner wall of the lock container 12, the other end of the reset torsion spring 161 is connected with the reset disc 16, and a torsion spring mounting groove 162 is further arranged on the reset disc 16 to be stably connected with the reset torsion spring 161. When the external force drives the rotating rod 10 to rotate, the rotating rod 10 drives the reset torsion spring 161 to twist, so that the reset torsion spring 161 can drive the reset disc 16 to rotate and reset after the external force is relieved, and then the rotating rod 10 is driven to rotate and reset. The scheme is easy to realize, and the lock cylinder 1 can be automatically reset when the external force is removed, so that the using method of the lock cylinder 1 is simplified. The second reset mechanism preferably comprises a reset spring 19, one end of the reset spring 19 is fixedly connected with the lock cylinder 12, the other end of the reset spring 19 is connected with one of the blades 11, and the blades 11 are driven to move along the circumferential direction of the rotating rod 10 through the elasticity of the reset spring 19 so as to reset to the locking position.
The resetting mechanism has the advantages of simplicity and easiness in use.
