[0045] Example 1

[0046] like Figure 1 、 Figure 2 and Figure 3 As shown, this embodiment provides a lock core structure, including a lock core 100, a lock tongue 300, and a lock tongue spring 500 connected to the lock tongue 300;

[0047] The rear end of the lock core 100 is provided with a boss 101, and the lock tongue 300 is provided with a first groove 301 that matches the boss 101. One side of the boss 101 contacts the side wall of the first groove 301, and there is a gap between the other side of the boss 101 and the side wall of the first groove 301.

[0048] The lock tongue 300 is unlocked by force, and after the force applied to the lock tongue 300 by the lock core 100 disappears, the compressed lock tongue spring 500 elastically resets and drives the first groove 301 to act on the boss 101. The boss 101 rotates along the first groove 301, causing the lock core 100 to rotate to the initial locking state, and the lock tongue 300 returns to the initial locking state.

[0049] Specifically, applying a rotational force to the boss 101 can drive the lock tongue 300 to move toward the interior of the lock core structure, compress the lock tongue spring 500, and achieve unlocking; when the rotational force applied to the boss 101 is removed, the lock tongue 300 moves toward the outside of the lock core structure under the action of the restoring force of the lock tongue spring 500, and returns to the initial locked state.

[0050] The present invention provides a lock core structure in which one side of the boss 101 contacts the side wall of the first groove 301, and a gap is formed between the other side of the boss 101 and the side wall of the first groove 301. The boss 101 can drive the lock tongue 300 to retract and compress the lock tongue spring 500. When the boss 101 is released, the lock tongue spring 500 provides a restoring force, returning the boss 101 and the lock tongue 300 to a locked state. After the key is inserted to unlock the lock, the lock tongue cooperates with the lock core and can automatically rotate and accurately return to the initial position when the key is released. At this time, the mechanical key can be removed. This solves the technical problem in the prior art that the lock tongue cannot automatically pop out after the lock core is unlocked, and the mechanical key cannot return to the initial position and be smoothly removed.

[0051] Example 2

[0052] like Figure 1 、 Figure 2 and Figure 3 As shown, this embodiment provides a lock core structure, including a lock core 100, a lock tongue 300, and a lock tongue spring 500 connected to the lock tongue 300;

[0053] The rear end of the lock core 100 is provided with a boss 101, and the lock tongue 300 is provided with a first groove 301 that matches the boss 101. One side of the boss 101 contacts the side wall of the first groove 301, and there is a gap between the other side of the boss 101 and the side wall of the first groove 301.

[0054] The lock tongue 300 is unlocked by force, and after the force applied to the lock tongue 300 by the lock core 100 disappears, the compressed lock tongue spring 500 elastically resets and drives the first groove 301 to act on the boss 101. The boss 101 rotates along the first groove 301, causing the lock core 100 to rotate to the initial locking state, and the lock tongue 300 returns to the initial locking state.

[0055] Specifically, applying a rotational force to the boss 101 can drive the lock tongue 300 to move toward the interior of the lock core structure, compress the lock tongue spring 500, and achieve unlocking; when the rotational force applied to the boss 101 is removed, the lock tongue 300 moves toward the outside of the lock core structure under the action of the restoring force of the lock tongue spring 500, and returns to the initial locked state.

[0056] The present invention provides a lock core structure in which one side of the boss 101 contacts the side wall of the first groove 301, and a gap is formed between the other side of the boss 101 and the side wall of the first groove 301. The boss 101 can drive the lock tongue 300 to retract and compress the lock tongue spring 500. When the boss 101 is released, the lock tongue spring 500 provides a restoring force, returning the boss 101 and the lock tongue 300 to a locked state. After the key is inserted to unlock the lock, the lock tongue cooperates with the lock core and can automatically rotate and accurately return to the initial position when the key is released. At this time, the mechanical key can be removed. This solves the technical problem in the prior art that the lock tongue cannot automatically pop out after the lock core is unlocked, and the mechanical key cannot return to the initial position and be smoothly removed.

[0057] The difference between this embodiment and the first embodiment is that:

[0058] When the lock tongue 300 is in the unlocked state, the first side wall of the boss 101 contacts the second side wall of the first groove; when the lock tongue 300 is in the locked state, the third side wall of the boss 101 contacts the fourth side wall of the first groove 301.

[0059] Specifically, the shape of the first side wall matches the shape of the second side wall.

[0060] Specifically, there is a rounded corner and / or a bevel between the first side wall and the third side wall. Such a design makes the boss 101 rotate more smoothly.

[0061] like Figure 4 and Figure 5As shown, it also includes a lock sleeve 200, and a first cavity is provided inside the lock sleeve 200 to accommodate the lock core 100, the lock tongue 300 and the lock tongue spring 500. A telescopic opening 201 for the lock tongue 300 to pass through is opened on one side of the lock sleeve 200, one end of the lock tongue spring 500 is connected to the inner wall of the lock sleeve 200 on the opposite side of the telescopic opening 201, and the other end of the lock tongue spring 500 is against the lock tongue 300.

[0062] Alternatively, a lock tongue spring positioning block 203 is provided on the inner wall of the lock sleeve 200 on the opposite side of the telescopic opening 201 , one end of the lock tongue spring 500 is connected to the lock tongue spring positioning block 203 , and the other end of the lock tongue spring 500 is against the lock tongue 300 .

[0063] Specifically, the locking tongue spring positioning block 203 is a shaft, and the locking tongue spring 500 is sleeved on the outside of the shaft, so that the extension and contraction directions of the locking tongue springs are in the same direction.

[0064] Example 3

[0065] like Figure 1 、 Figure 2 and Figure 3 As shown, this embodiment provides a lock core structure, including a lock core 100, a lock tongue 300, and a lock tongue spring 500 connected to the lock tongue 300;

[0066] The rear end of the lock core 100 is provided with a boss 101, and the lock tongue 300 is provided with a first groove 301 that matches the boss 101. One side of the boss 101 contacts the side wall of the first groove 301, and there is a gap between the other side of the boss 101 and the side wall of the first groove 301.

[0067] The lock tongue 300 is unlocked by force, and after the force applied to the lock tongue 300 by the lock core 100 disappears, the compressed lock tongue spring 500 elastically resets and drives the first groove 301 to act on the boss 101. The boss 101 rotates along the first groove 301, causing the lock core 100 to rotate to the initial locking state, and the lock tongue 300 returns to the initial locking state.

[0068] Specifically, applying a rotational force to the boss 101 can drive the lock tongue 300 to move toward the interior of the lock core structure, compress the lock tongue spring 500, and achieve unlocking; when the rotational force applied to the boss 101 is removed, the lock tongue 300 moves toward the outside of the lock core structure under the action of the restoring force of the lock tongue spring 500, and returns to the initial locked state.

[0069] The present invention provides a lock core structure in which one side of the boss 101 contacts the side wall of the first groove 301, and a gap is formed between the other side of the boss 101 and the side wall of the first groove 301. The boss 101 can drive the lock tongue 300 to retract and compress the lock tongue spring 500. When the boss 101 is released, the lock tongue spring 500 provides a restoring force, returning the boss 101 and the lock tongue 300 to a locked state. After the key is inserted to unlock the lock, the lock tongue cooperates with the lock core and can automatically rotate and accurately return to the initial position when the key is released. At this time, the mechanical key can be removed. This solves the technical problem in the prior art that the lock tongue cannot automatically pop out after the lock core is unlocked, and the mechanical key cannot return to the initial position and be smoothly removed.

[0070] This embodiment differs from the above embodiments in that:

[0071] The first groove 301 is provided on a side of the lock tongue 300 facing the lock core 100 , and a second groove 302 for accommodating the lock tongue spring 500 is provided on a side of the lock tongue 300 facing away from the lock core 100 .

[0072] One side of the second groove 302 is open, one end of the lock tongue spring 500 is connected to the second groove 302 , and the other end of the lock tongue spring 500 is connected to the lock sleeve 200 .

[0073] More specifically, Figure 8 and Figure 9 As shown, the second groove 302 includes an open end and a closed end, and the open end is arranged toward the lock sleeve 200. The end of the lock tongue spring 500 can pass through the open end and abut against the closed end, thereby realizing compression of the lock tongue 300 on the lock tongue spring 500; after releasing the mechanical key, the lock tongue spring 500 can apply a restoring force to the closed end to realize restoration to the initial state.

[0074] Example 4

[0075] like Figure 1 、 Figure 2 and Figure 3 As shown, this embodiment provides a lock core structure, including a lock core 100, a lock tongue 300, and a lock tongue spring 500 connected to the lock tongue 300;

[0076] The rear end of the lock core 100 is provided with a boss 101, and the lock tongue 300 is provided with a first groove 301 that matches the boss 101. One side of the boss 101 contacts the side wall of the first groove 301, and there is a gap between the other side of the boss 101 and the side wall of the first groove 301.

[0077] The lock tongue 300 is unlocked by force, and after the force applied to the lock tongue 300 by the lock core 100 disappears, the compressed lock tongue spring 500 elastically resets and drives the first groove 301 to act on the boss 101. The boss 101 rotates along the first groove 301, causing the lock core 100 to rotate to the initial locking state, and the lock tongue 300 returns to the initial locking state.

[0078] Specifically, applying a rotational force to the boss 101 can drive the lock tongue 300 to move toward the interior of the lock core structure, compress the lock tongue spring 500, and achieve unlocking; when the rotational force applied to the boss 101 is removed, the lock tongue 300 moves toward the outside of the lock core structure under the action of the restoring force of the lock tongue spring 500, and returns to the initial locked state.

[0079] The present invention provides a lock core structure in which one side of the boss 101 contacts the side wall of the first groove 301, and a gap is formed between the other side of the boss 101 and the side wall of the first groove 301.
