Detailed Description
As shown in fig. 1 to 7, the clutch device of the lock body comprises a clutch base 1 and a rotor 3.
The clutch seat 1 is provided with a clutch pin 5 which can be inserted into or withdrawn from the rotor 3, when the clutch pin 5 is inserted into the rotor 3, the rotor 3 can synchronously rotate along with the clutch seat 1, when the clutch pin 5 is withdrawn from the rotor 3, the rotor 3 can relatively rotate with the clutch seat 1, specifically, the rotor 3 is provided with a clamping hole 31, the lock body is provided with a pushing mechanism 7, a spring 6 is arranged between the clutch pin 5 and the clutch seat 1, and the clutch pin 5 is withdrawn from the rotor 3 and retracted into the clutch seat 1 under the action of the spring 6; under the urging of the urging mechanism 7, the clutch pin 5 is inserted into the card hole 31 against the action of the spring 6.
The pushing mechanism 7 comprises a motor 71 which is fixedly arranged in the lock body, the motor 71 is connected with a push plate 72 through a speed reducing mechanism, the push plate 72 is an arc-shaped plate with a central shaft coaxial with a rotating central shaft of the clutch base 1, and the push plate 72 moves up and down along the axial direction of the clutch pin 5 under the action of the motor 71.
When the lock is used, the handle is connected with the rotor 3 through square steel, the lock body is provided with the lock bolt 8, the clutch base 1 is sleeved with the clutch stirring piece 81 which is in matched linkage with the lock bolt 8, and the clutch base 1 rotates to drive the clutch stirring piece 81 to rotate together to lock or unlock the lock bolt 8. When the lock is locked, the rotor 3 can rotate relative to the clutch seat 1, the rotor 3 and the clutch seat 1 are in a free state, namely the handle and the lock body are in a free state and can only idle, and therefore the anti-theft function is achieved. When the lock needs to be unlocked, after the lock body is unlocked by sending an electronic command in a mode of inserting a key into the lock cylinder or pressing a fingerprint and the like, the pushing mechanism 7 pushes the clutch pin 5 to overcome the action of the spring 6 and insert the clutch pin into the clamping hole 31, and the handle is linked with the lock bolt 8 through square steel, the rotor 3, the clutch seat 1 and the clutch toggle piece 81, so that unlocking is realized.
Under the structure, if an electronic command is sent out in a mode of inserting a key into a lock cylinder or pressing a fingerprint and the like, the lock body cannot be locked, so that in the embodiment, the rotor 3 is provided with the clamping groove 32, the clamping pin 11 is arranged on the clutch seat 1, the elastic element 12 is arranged between the clutch seat 1 and the clamping pin 11, and the clamping pin 11 is clamped in the clamping groove 32 under the action of the elastic element 12 in a normal state; when the rotor 3 rotates along the counterclockwise direction around the central shaft, the clutch base 1 and the rotor 3 rotate synchronously, as shown in figure 5; when rotor 3 is rotated clockwise about its central axis, bayonet 11 is moved away from bayonet 32 against the action of resilient member 12, and rotor 3 is rotated relative to clutch plate 1, as shown in figure 6.
