the working principle is as follows: the gear 1 rotates under the driving of the output force of the driving motor 51, a contact force is applied to the second meshing part 22 through the first meshing part 12, the rotary driving part 2 rotates around a rotating shaft of the rotary cylinder 21 according to a preset direction, the rotary driving part 2 is far away from the gear 1 in a translational motion along the rotating shaft of the rotary cylinder 21, when the second salient point 32 is meshed with and fixed to the first salient point 31, the second meshing part 22 is far away from the first meshing part 12 in a translational motion and is static, the separation of the rotary driving part 2 and the gear 1 can be prevented, the gear 1 and the rotary driving part 2 are enabled to keep synchronous rotation, the protruding block 24 on the tray 23 is embedded into the groove, the output part 4 is driven to rotate, the gear 1, the rotary driving part 2 and the output part 4 are enabled to realize synchronous rotation, the locking ruler is driven to rotate according to the preset direction through the movement of the driving rod 41. To the mode that exerts torsion through the actuating lever both ends and drive, because the actuating lever is connected with the lock chi, consequently, can drive the motion of lock chi when the actuating lever rotates, no longer describe herein.
under the action of external torque force, the knob rotates to drive the driving rod 41 to rotate, and then the output piece 4 is driven to rotate, so that the lock ruler rotates according to the preset direction to drive the lock tongue to move, the lock tongue locks or unlocks an object to be locked, and the dual purposes of machinery and electricity are realized.
The clutch and transmission structure, lock and the product that this embodiment disclosed, rotatory driving medium includes: the cylinder is rotated, and the gear is provided with a through hole in a penetrating way. A first occluding part is arranged on the inner side of the through hole, a second occluding part is arranged on the outer side of one end of the rotating cylinder, and the first occluding part is abutted against the second occluding part after the rotating cylinder penetrates into the through hole; or the circumferential driving wall is arranged on the annular through hole, the first occlusion part is arranged on the outer side of the circumferential driving wall, the second occlusion part is arranged on the inner side of one end of the rotating cylinder, and after the circumferential driving wall is sleeved on the rotating cylinder, the first occlusion part is abutted against the second occlusion part. That is, penetrate the through-hole or cover through the rotator cover through-hole circumference actuating wall through the rotator, make first interlock spare contradict with the second interlock spare to, the gear can be spacing in circumference when exerting the contact force for the second interlock spare through first interlock spare, then, has reduced the probability that the driving medium takes place the dislocation, has reduced transmission error promptly, has improved the transmission precision.
For the clutch, one end of the output piece is detachably connected with the tray; one end of the output piece is subjected to torsion force and then drives an external object arranged on the output piece to move, or the other end of the output piece is used for receiving external driving torsion force so as to drive the external object arranged on the output piece to move. It is achieved that the external object can be driven to move by one end or the other end of the output member. That is, double-ended driving of the clutch is achieved. And, because the transmission structure axial is spacing, reduced the probability that the driving medium takes place the dislocation, then, improved the stable transmission of clutch.
it should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
