Description

Technical Field

[0001] The present invention relates to the technical field of locks, and in particular to a push-button mechanical password lock cylinder and a lock thereof. Background Technology

[0002] Key-press password lock cylinders are widely used in daily life and are generally divided into electronic key-press password lock cylinders and mechanical key-press password lock cylinders. Both types of locks require pressing the correct key and then turning the door handle to unlock.

[0003] In the related art, commonly used mechanical key combination locks usually have several groups of keys and a door handle on the lock. The keys are linked to the lock core, and the door handle is also linked to the lock core. When the keys are pressed in the wrong order, the lock core is in a locked state and cannot operate. Therefore, the door handle cannot drive the lock core to operate and the door lock cannot be opened. The lock can only be opened by pressing the keys in the correct order.

[0004] However, when this type of lock is in use, the door handle and the lock core are in a linked state. If the button pressing sequence is wrong, turning the door handle will not unlock the door, but the torque applied to the door handle will still be transmitted to the lock core, causing the linkage structure of the door handle and the lock core to be easily worn, deformed, bent, etc., causing the lock core to be damaged, and the problem of being unable to unlock the door after long-term use is easy to occur. SUMMARY OF THE INVENTION

[0044] In this embodiment, if Figure 7 As shown in FIG. 1 , the reset assembly 15 includes a reset push rod 33, a reset spring 34 is provided at the left end of the reset push rod 33, and a positioning spring 32 is provided on the surface of the reset push rod 33. When the external force pushing the reset push rod 33 disappears, the reset spring 34 pushes the reset push rod 33 to reset.

[0045] In this embodiment, if Figure 8 As shown in FIG. 1 , the unlocking push rod assembly 18 includes an unlocking push rod 35 , a surface of which is provided with an unlocking push rod button shaft 36 , and a right end of the unlocking push rod 35 is provided with an unlocking push rod assembly spring 37 .​​​​​

[0046] In this embodiment, as Figure 9 shown, the code-changing component 21 includes a code-changing positioning plate 38, a code-changing component key shaft 39 is installed on the side of the code-changing positioning plate 38, and a code-changing component spring 40 is provided on the surface of the code-changing positioning plate 38.

[0048] The present invention also provides a lock, and the lock includes the above-mentioned push-button mechanical lock core.

[0049] In this embodiment, as Figure 5 shown, a lock further includes a panel assembly 6, the lock core housing 2 is installed inside the panel assembly 6, a handle connecting member 85 is installed inside the panel assembly 6, a square tube moving member 84 is installed inside the handle connecting member 85, an unlocking reset member 81 is sleeved on the surface of the handle connecting member 85, a partition pin 82 passing through the unlocking reset member 81 is provided on the surface of the unlocking reset member 81, and an unlocking spring 83 is sleeved on the surface of the partition pin 82, and a pushing member 80 is provided on the surface of the unlocking reset member 81.

[0050] Specifically, when in use:

[0051] Coding and code confirmation of the lock, Figure 1It is in the initialization state. Press the key shaft 39 of the code-changing component forcefully. There is an inclined push linkage mechanism between the key shaft 39 of the code-changing component and the code-changing positioning plate 38. The key shaft 39 of the code-changing component moves downward, and the code-changing positioning plate 38 moves forward. Since the convex strip on the code-changing positioning plate 38 is inserted into the square hole of the coding part 42, the coding part 42 will move forward together with the code-changing positioning plate 38, separating the coding key shaft 41 from the coding part 42. Press the coding key shaft 41. Because the coding key shaft 41 has a clamping position, it forms a buckle with the positioning spring piece 32 of the reset component 15. At this time, release the key shaft 39 of the code-changing component. The code-changing component spring 40 of the code-changing component 21 rebounds to make the code-changing positioning plate 38 and the coding part 42 return to their original positions. Because of the straight-tooth structure between the key shaft 39 of the code-changing component and the coding part 42, the positions of the key shaft 39 of the code-changing component and the coding part 42 are changed, thus achieving the effect of setting the password. At this time, press down or lift the door handle. The unlocking and resetting part 81 of the panel component 6 contacts the reset push rod 33, pushing the reset component 15 to move forward. The positioning spring piece 32 on the reset component 15 moves along. At this time, the key shaft 39 of the code-changing component buckled with the positioning spring piece 32 moves upward together with the coding part 42 under the action of the coding component spring 43, limited by the lock core cover plate 1, thus achieving code confirmation.

[0052] Password reset initialization of the lock. Press the coding key shaft 41. Because the coding key shaft 41 has a clamping position, it forms a buckle with the positioning spring piece 32 of the reset component 15, making the coding part 42 in the password setting state return to the initialization position. While pressing the key shaft 39 of the code-changing component forcefully, press down or lift the door handle. The unlocking and resetting part 81 of the panel component 6 contacts the reset push rod 33, pushing the reset component 15 to move forward. The positioning spring piece 32 on the reset component 15 moves along. At this time, the coding key shaft 41 returns to the position in the initialization state under the combined action of the first reset spring group 17 and the coding component spring 43. Release the key shaft 39 of the code-changing component. At this time, the lock core returns to the initialization state as Figure 1 shown.

[0053] After the lock core is coded and the code is confirmed, when there is no password set, the coding part 42 and the unlocking push rod 35 are in a clearance state, while when there is a password set, the coding part 42 and the unlocking push rod 35 are in an inserted state. If the password input is incorrect, the unlocking push rod component 18 cannot move, and the unlocking push rod key shaft 36 cannot be pressed. At this time, the partition pin 82 is not inserted into the square tube moving part 84, and the door handle head is in an idle rotation state.

[0054] After the password is entered correctly, there is an inclined push linkage mechanism between the unlocking push rod 35 and the unlocking push rod button shaft 36. When the unlocking push rod button shaft 36 is pressed, the unlocking push rod 35 moves to contact the partition pin 82 and displace together. There is a tooth buckle on the unlocking push rod button shaft 36, and when the unlocking push rod button shaft 36 is pressed down, it engages with the positioning spring piece 32. At this time, the partition pin 82 is inserted into the square tube moving part 84, and the square tube moving part 84 is fixed to the handle. When the handle is pressed down, the square tube moving part 84 drives the square rod to rotate, thus achieving unlocking. During the pressing down process, the unlocking reset part 81 of the panel assembly 6 contacts the reset push rod 33, pushing the reset assembly 15 to move forward. The positioning spring piece 32 on the reset assembly 15 moves along with it. At this time, the unlocking push rod button shaft 36 that engages with the positioning spring piece 32 is reset under the action of the first reset spring group 17, and the coding assembly 28 also returns to the state where no password is entered.

[0055] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
