Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 to 3, an anti-theft knob switch device provided in an embodiment of the present invention may be used in an intelligent lock, and includes a fixing base 120 connected to a lock body 910, and a manual control component 200 connected to or separated from an unlocking rotation shaft 920 of the lock body 910, wherein the lock body 910 may be installed inside a door, the manual control component 200 is installed on the fixing base 120, and a reset member is disposed between the fixing base 120 and the manual control component 200

Specifically, the manual control component 200 can rotate circumferentially and slide axially relative to the fixing base 120. The reset element is an elastic element for axially resetting the manual control element 200, or the reset element may also be a magnetic element (for example, one ends with the same polarity are arranged close to each other, for example, the manual control element 200 is reset by the principle of like polarity repulsion). Manual control part 200 is in separate with unblock pivot 920 under the elastic force effect of elastic component, when pressing manual control part 200 back, manual control part 200 can be connected with the unblock pivot 920 of tool to lock body to can drive the unblock pivot through rotating manual control part 200 and rotate, realize the switch lock, fail safe nature is good.

Specifically, as shown in fig. 1 to 5, the manual control component 200 includes a manual control knob 110 for pressing and rotating and a clutch component 200, the manual control knob 110 is connected to one end of the clutch component 200, and the other end of the clutch component 200 is disposed in the fixing base 120 and is provided with a connecting structure for connecting or separating with the unlocking rotation shaft 920. The user cannot directly rotate the manual control knob 110 to actuate the unlocking rotation shaft 920 (as shown in fig. 7), but needs to first axially move (e.g., press) the manual control knob 110 and the clutch member 200 to connect the clutch member 200 and the unlocking rotation shaft 920 (as shown in fig. 8), and then can rotate the manual control knob 110 away from the initial position to actuate the unlocking rotation shaft 920. Under the locking state, a lawless person can be prevented from directly poking the manual control knob 110 to unlock by extending a tool into the door from the outside of the door through the door gap, and the safety and reliability are improved. When the manual control knob 110 is in the locked state or the unlocked state, the clutch member 200 and the manual control knob 110 are automatically reset under the action of the elastic member, that is, the clutch member 200 is separated from the unlocking rotation shaft 920 (as shown in fig. 7), and cannot be unlocked by directly rotating the manual control knob 110.

Specifically, as shown in fig. 1 to 5, the connecting structure may be a sleeve portion 210, the sleeve portion 210 has an inner hole for receiving an end of the unlocking rotation shaft 920, a cross section of the unlocking rotation shaft 920 may be non-circular (e.g., D-shaped, rectangular, etc.), and a shape of the inner hole of the sleeve portion 210 may match a shape of the end of the unlocking rotation shaft 920. The clutch member 200 axially slides toward the unlocking rotation shaft 920, and the inner hole of the sleeve portion 210 can be fitted to the end of the unlocking rotation shaft 920.
