[0045] The lock core 3 includes a lock core rod 31. One end of the lock core rod 31 passes through the lock core box 23 and is connected to an unlocking plate 35 via a connecting plate 34. The unlocking plate 35 abuts against the limit device. A sliding groove is provided on the lock core rod 31. The lock core rod 31 is wrapped with a password component 4.

[0046] The lock core rod 31 is slidably connected to the lock core box 23, and the unlocking plate 35 abuts against the panel 28 on one side of the principle limiting device.

[0047] The unlocking plate 35 has the same height as the wedge plate 15 . A trapezoidal groove 36 is provided on the unlocking plate 35 facing the wedge plate 15 . The head of the wedge plate 15 is inserted into the trapezoidal groove 36 and abuts against the right inclined surface of the trapezoidal groove 36 .

[0048] The panel 28 cooperates with the limiting device to clamp the unlocking plate 35, thereby limiting the rotation and movement of the lock cylinder 3.

[0049] When the panel 28 rotates downward, the wedge plate 15 squeezes the trapezoidal groove 36 to move the lock core rod 31 to the right. At the same time, the lock core rod 31 and the lock core box 23 rotate downward, and the lock plate 21 is disengaged from the flip cover 12 to achieve unlocking.

[0050] The slide groove includes an unlocking groove 32, which is located on the top surface of the lock core rod 31 and is arranged axially along the lock core rod 31. Three annular grooves 33 are evenly arranged in the middle of the unlocking groove 32.

[0052] A slot 47 is provided inside the digital dial 46, the slot 47 opening facing left, and a clamping protrusion 43 is provided on the surface of the gear sleeve 41, which fits into the slot 47. The slot 47 can limit the clamping protrusion 43 from moving rightward, thereby limiting the gear sleeve 41 from moving rightward.

[0053] The digital dial 46 is inserted into the limiting groove 26 and can rotate along its own axis in the limiting groove 26 .

[0054] Ten grooves 48 are evenly arranged axially on the outer side surface of the number dial 46. The ten grooves 48 divide the outer side surface of the number dial 46 into ten equal areas for engraving the ten numbers 0-9.

[0055] The head of the card plate 27 is inserted into the groove 48. When the digital dial 46 rotates, the card plate 27 slides along the outer side of the digital dial 46, providing a certain resistance each time it slides through the groove 48, ensuring that the rotation angle is the same each time.

[0056] When the digital dial 46 rotates, the gear sleeve 41 can be driven to rotate via the engaging protrusion 43 .

[0057] The limiting block 42 is located in the annular groove 33 , and the width of the limiting block 42 is the same as that of the unlocking groove 32 .

[0058] The gear sleeve 41 can rotate around the axis of the lock core rod 31, causing the limit blocks 42 to slide along the annular groove 33. When all the limit blocks 42 are aligned with the unlocking groove 32, the lock core rod 31 can move left and right. When any limit block 42 is not aligned with the unlocking groove 32, the lock core rod 31 cannot move.

[0059] When the operator of this embodiment uses this device, he rotates the digital dial 46 to drive the gear sleeve 41 to rotate, so that the limit blocks 42 slide along the annular groove 33, and all the limit blocks 42 are controlled to align with the unlocking groove 32, so that the lock core rod 31 can move left and right.

[0060] Press the lower half of the panel 28 inward, driving the panel 28 to rotate downward and inward, thereby driving the lock body 2 and the lock core 3 to rotate downward and inward, and the wedge plate 15 squeezes the trapezoidal groove 36 to make the lock core rod 31 move to the right. At the same time, the lock core rod 31 and the lock core box 23 rotate downward, and the lock plate 21 disengages from the flip cover 12 to achieve unlocking.

[0061] Example 2:

[0062] A spring 45 is provided in the outermost gear sleeve 41 , and an insert plate 44 is provided on the outer end face of the outermost gear sleeve 41 . The outer top of the insert plate 44 is an inclined surface, and the outer top of the insert plate 44 abuts against the bottom side of the extrusion plate 17 .

[0063] When the operator of this embodiment uses the device, he rotates the digital dial 46 to drive the gear sleeve 41 to rotate, so that the limit blocks 42 slide along the annular groove 33, and all the limit blocks 42 are controlled to be aligned with the unlocking groove 32.

[0064] Lifting the panel 28 upwards can drive the lock core box 23, the lock core 3 and the password assembly 4 to move upwards.

[0065] At this time, the inserting plate 44 is squeezed by the squeezing plate 17 and moves to the left, thereby driving all the gear sleeves 41 to slide to the left, thereby disengaging the engaging protrusion 43 from the groove 48.

[0066] At this moment, the number dial 46 can rotate independently without affecting the gear sleeve 41. The password can be changed by rotating the number dial 46.

[0067] Changing your password regularly can improve security.
