Locating plate 4 be provided with 6 positioning hole, positioning hole be used for cup jointing the wrench disk 2, 4 bottom surfaces of locating plate be provided with the slip recess, 4 one end of locating plate be provided with the reset hole about the spout that resets that corresponds.

The unlocking push rod 5 is connected with the middle shell 12 in an elastic clamping mode through the assembling square groove, one end of the assembling square groove is exposed out of the middle shell 12, and the two spring shafts of the unlocking push rod 5 are elastically clamped with an inner side baffle at the bottom of the middle shell 12 and used for resetting. And 3 unlocking bulges are arranged on two sides of the unlocking push rod 5. And a reset barrier strip is arranged at the top of the unlocking push rod 5. Linkage piece 6 set up unblock push rod 5 both sides, the outside limit of two linkage pieces 6 is provided with 3 angle respectively protrudingly, angle protruding when the unblock state with the laminating of

angle groove

33, 6 vertical direction upper portions of linkage piece be provided with the linkage recess, 3 the linkage recess with password update module cooperation, 6 medial surfaces of linkage piece be provided with 3 inboard archs, inboard protruding with the protruding cooperation locking of unblock push rod 5. The inner side of the linkage sheet 6 is also provided with opposite spring positioning columns, and a pushing spring is arranged between the pair of opposite spring positioning columns and used for pushing the two linkage sheets 6 to move back and forth so as to combine the angle protrusion with the angle groove 33.

The unlocking module comprises a positioning plate 4, an unlocking push rod 5 and a linkage plate 6. The adjusting unit comprises a reset push rod 7, one end of the top of the reset push rod 7 is provided with a sliding bulge protruding out of the panel 11 and sleeved in the reset hole in a sliding mode, crosspieces are arranged on two sides of the reset push rod 7, and the crosspieces in the 3 groups are in sliding fit with the linkage grooves. The center of the reset push rod 7 is provided with a sliding square hole which is sleeved on the reset barrier strip at the top of the unlocking push rod 5.

The clutch unit includes a locking frame 8, a locking post 82, a locking spring 83 and a locking base 9. 2 group the stop base 9 respectively through the fix with screw bottom the inside bottom surface of drain pan 13, every stop base 9 respectively along same straight line evenly be provided with 3 spring screens, stop spring 83 one end fix the spring screens on, the other end connect stop post 82 bottom surface. The upper part of the clamping column 82 can be sleeved with the clamping through hole 35 to limit the rotation of the lock disc 3. The two sides of the clamping frame 8 are respectively provided with a positioning strip, the positioning strips are respectively provided with 3 positioning column holes, and the clamping column 82 and the clamping spring 83 are sleeved in the positioning column holes. The clamping frame 8 is also provided with a clutch button 81 sleeved in the button hole of the bottom shell 13, and the clutch button 81 is fixedly connected with the positioning strips at the two sides through a cross beam.

In the locked state: the lock dish 3 pass through the reference column with the torsion dish 2 on 22 through-holes peg graft and produce the swivelling joint and move, two sets of linkage piece 6 because the protruding not with the angular groove 33 laminating of outside angle, can only with the lock dish 32 circumference side slide tangent. At the moment, the linkage pieces 6 are in a minimum interval state, and the inner side protrusions and the unlocking protrusions are clamped and locked, so that the unlocking push rod 5 cannot move. The reset stop strip limits the reset square hole, so that the reset push rod 7 cannot slide. The stop column 82 is not aligned with the stop through hole 35, and the clutch button 81 cannot be pressed.

An unlocking state: through twisting knob to unblock password registration, through the transmission shaft drive the twist disk 2 with the coaxial rotation of lock disk 3, lock disk 3 rotate when the correct unblock password position the promotion spring promote 6 back of the body motion of linkage piece, the protruding joint of angle advance angle groove 33, as whole 6 the protruding laminating of angle groove 33 after, 2 group linkage piece 6 between be in the biggest state of interval, this moment inboard protruding with the protruding separation of unblock, unblock push rod 5 can promote the completion unblock.

The password replacing function is realized in the following mode: under the lock body is in the unblock state, promote the slip arch, reset push rod 7 slide, 7 crossbeams butt both sides of reset push rod linkage piece 6 for linkage piece 6 joint lock dish 3 all the time. Simultaneously, the clutch button 81 is pressed, the blocking frame 8 rises, and the blocking spring 83 pushes the blocking column 82 to be inserted into the blocking through hole 35. The knob is twisted, and 6 positioning bulges and the disc-twisting surface groove are dislocated because the relative sliding force is smaller than the clamping force, so that the lock disc 3 does not rotate together with the knob any more.

At this time, the knob is rotated, the knob and the torsion disc 2 rotate together, but the lock disc 3 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 7 and the clutch button 81 are loosened. The unlocking push rod 5 is elastically reset by a spring, the reset push rod 7 is reset under the action of the restoring force of the restoring spring, and the clamping state of the linkage sheet 6 is released. After the clutch button 81 is released, the stop spring 83 rebounds and resets the stop frame 8, and the stop frame 8 drives the stop post 82 to be drawn away from the stop through hole 35.

6 the location protruding with the twist disk face recess grafting state this moment be greater than the resistance, twist disk 2 with lock dish 3 can rotatory linkage again, the knob registration this moment be the new password of lock body after the modification.

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.
