Detailed Description

The present invention will be further described with reference to the following examples.

Examples

A door handle clutch device as shown in fig. 1-5, mainly used for taking the handle that the fingerprint control unblanked to use, be equipped with fingerprint identification module 1 on the handle, clutch device includes the rotation piece 3 with the linkage of square shaft 2, locate in the handle and produce the separation and reunion piece 4 of separation and reunion with rotation piece 3, locate in the handle drive separation and reunion piece 4 and rotate the motor 5 that piece 3 produced the separation and reunion, motor 5 is connected with control panel 6 electricity, fingerprint identification module 1 and control panel 6 are prior art, do not explain here in detail, but separation and reunion piece 4 is located in the handle of straight reciprocating motion in this embodiment, be equipped with linkage cooperation structure between separation and reunion piece 4 and rotation piece 3, when separation and reunion piece 4 moved to cooperate with rotation piece 3, square shaft 2 and handle produce the linkage and unblank. In this embodiment, the linkage and engagement structure includes a detent 31 on the rotating member 3, a detent protrusion 41 on the clutch member 4 for inserting into the detent 31 on the rotating member 3, and the clutch member 4 is linked with the rotating member 3 after the detent protrusion 41 is inserted into the detent 31.

In order to realize the linear motion of the clutch member 4, in the embodiment, the output end of the motor 5 is provided with a screw rod 51, and the corresponding clutch member 4 is provided with an internal thread which is in threaded fit with the screw rod 51. Still include mount pad 7, mount pad 7 is fixed in the handle, installs battery 8 in the mount pad, is equipped with the mouth 61 that charges for the battery charges on the control panel that corresponds, is equipped with power supply connector male hole groove on hand corresponding position, and the protruding 41 sliding fit of card of separation and reunion piece 4 is equipped with the gliding spout 71 of the protruding 41 of card that supplies separation and reunion piece 4 on mount pad 7 on the mount pad 7. The screw rod 51 is driven to rotate by the motor 5, the clutch 4 is in threaded connection with the screw rod 51, and the clutch 4 is in sliding fit with the mounting seat 7, so that the clutch 4 is pushed to slide along the sliding groove 71 on the mounting seat 7 when the motor 5 drives the screw rod 51 to rotate, the handle can be linked with the square shaft 2 when the clutch 4 slides to the clamping position 31 of the rotating part 3, and the unlocking purpose can be realized by rotating the handle.

In this embodiment, the two clamping slots 31 are mirror images, so that the two clamping slots can be installed in two directions during installation.

The foregoing shows and describes the basic principles, essential features, and advantages of the invention.
