Detailed Description

The technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments described herein without the need for inventive work, are within the scope of the present invention.

In the embodiment of the utility model, as shown in the attached figures 1-2, the knob clutch structure comprises a twisting disc 1, a lock disc 2, a clamping frame 3, a clamping column 4, a clamping spring 5 and a clamping base 6. The bottom surface of the twisting disc 1 is uniformly provided with 10 twisting disc surface grooves 11 around the central hole of the twisting disc 1. The lock disc 2 comprises a lock disc shaft 21 and a lock disc surface 22, the lock disc shaft 21 is a round shaft, 6 groups of positioning bulges are arranged on the convex surface of the lock disc 2, and the lock disc surface 22 is provided with a clamping through hole 23 which is perpendicular to the lock disc surface 22. The positioning protrusion can be inserted into the torsion disc surface through hole 11 in a state that the lock disc surface 22 is attached to the torsion disc 1 surface.

2 group block base 6 pass through the fix with screw respectively the inside bottom surface of drain pan, every block base 6 evenly be provided with 3 spring screens 32 along the collinear respectively, 5 one end of block spring fix spring screens 32 on, the other end connect 4 bottom surfaces of block post. The upper part of the clamping column 4 can be sleeved with the clamping through hole 23 to limit the rotation of the lock disc 2. The two sides of the clamping frame 3 are respectively provided with a positioning strip, the positioning strips are respectively provided with 3 positioning column holes, and the clamping column 4 and the clamping spring 5 are sleeved in the positioning column holes. The clamping and stopping frame 3 is also provided with a clutch button 31 sleeved in the button hole of the bottom shell, and the clutch button 31 is fixedly connected with the positioning strips at the two sides through a cross beam. The knob clutch structure of the coded lock comprises a clutch button 31, a stop frame 3 ascends, and a stop spring 5 pushes a stop column 4 to be inserted into a stop through hole 23. The knob is twisted, 6 positioning bulges and the disc-twisting surface groove 11 are dislocated because the relative sliding force is smaller than the clamping force, so that the lock disc 2 does not rotate together with the knob.

When the clutch button 31 is pressed, the blocking frame 3 rises, and the blocking spring 5 pushes the blocking column 4 to be inserted into the blocking through hole 23. The knob is twisted, 6 positioning bulges and the disc-twisting surface groove 11 are dislocated because the relative sliding force is smaller than the clamping force, so that the lock disc 2 does not rotate together with the knob. At this time, the knob is rotated, the knob and the torsion disc 1 rotate together, but the lock disc 2 is in an unlocking state and does not rotate along with the knob any more, and after the knob stops rotating, the reset push rod and the clutch button 31 are loosened. The unlocking push rod is elastically reset by a spring, and the reset push rod resets under the action of the restoring force of a return spring to release the clamping state of the linkage sheet. After the clutch button 31 is released, the stop spring 5 rebounds and resets the stop frame 3, and the stop frame 3 drives the stop column 4 to be drawn away from the stop through hole 23. The 6 positioning bulges and the twisting disc surface groove 11 are in an inserted state and are larger than resistance force, and the twisting disc 1 and the lock disc 2 can be in rotary linkage again.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.
