Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0028] The embodiments of the present utility model will be described in detail below with reference to the drawings. Embodiment 1:

[0029] As Figures 1-5 shown, an automatically locking mechanical lock includes a lock body 1 and a button box 4. The lock body 1 is installed on the door panel, and the button box 4 is installed on the door frame. One end of the button box 4 is provided with a plurality of buttonholes 9. A locking tongue rod 14 is slidably connected inside the lock body 1. A second spring 15 is fixedly connected between the locking tongue rod 14 and one end of the lock body 1. One end of the locking tongue rod 14 is rotatably connected to an inclined tongue assembly. A leaf spring 19 and a contact 20 are fixedly connected inside the buttonhole 9. One end of the contact 20 is electrically connected to a warning light 5, and the warning light 5 is fixedly connected to the button box 4 at one end.

[0030] The inclined tongue assembly includes a small inclined tongue 17, a copper column 18, and a third spring 21. One end of the small inclined tongue 17 is rotatably connected to the locking tongue rod 14. One end of the copper column 18 is fixedly connected to the small inclined tongue 17. Both ends of the third spring 21 are respectively fixedly connected to the small inclined tongue 17 and the locking tongue rod 14.

[0031] When in use, rotate the door panel to dock the lock body 1 onto the buckle box 4. At this time, when one end of the lock tongue rod 14 contacts the buckle box 4 with its arc-shaped surface, it will contract inward. Then, after aligning with the buckle hole 9, it will pop out under the action of the second spring 15. The other end of the lock tongue rod 14 is flat, so it cannot be opened in the reverse direction to achieve self-locking.

[0032] After the lock tongue rod 14 is inserted into the buckle hole 9, the inclined tongue assembly will unfold. The small inclined tongue 17 pops out under the action of the third spring 21, inserts the copper column 18 at one end between the two leaf springs 19, and squeezes the leaf springs 19 apart. At this time, the leaf springs 19, the copper column 18, and the contact 20 are in mutual contact to connect the circuit of the warning light 5. The warning light 5 is preferably a red light, which can prompt the user that the lock is normally locked. When the warning light 5 does not light up after locking the door, it indicates that the device has a malfunction, and the lock tongue rod 14 and the inclined tongue assembly have not moved to the normal position and have not been locked correctly.

[0033] In this embodiment, a buzzer 6 is fixedly connected to one end of the buckle box 4, and a trigger switch 22 is slidably connected to one side of the buckle box 4. A fourth spring 23 is fixedly connected between the trigger switch 22 and one end of the buckle box 4; when the lock body 1 fits against one end of the buckle box 4, it will squeeze the trigger switch 22, causing the trigger switch 22 to move inward to connect the buzzer 6 circuit. At this time, if the warning light 5 does not light up normally, the buzzer 6 is activated to warn the user.

[0034] In this embodiment, a battery 2 and a photovoltaic panel 3 are fixedly connected to one side of the buckle box 4. One end of the battery 2 is electrically connected to the warning light 5 and the buzzer 6. When the device is installed outdoors, the battery 2 can be charged by the photovoltaic panel 3 to energize the warning light 5 and the buzzer 6.

[0035] In this embodiment, a keyhole 8 is fixedly connected to one side of the lock body 1, and a lock post 10 is drivingly connected to one end of the keyhole 8. The keyhole 8 can insert a key to rotate the lock post 10, and the lock post 10 is inserted into the buckle hole 9 to fix the device and prevent it from being opened quickly.

[0036] In this embodiment, a cover plate 7 is fixedly connected to one end of the lock body 1, and a lever 16 is slidably connected to one end of the cover plate 7. One end of the lever 16 is fixedly connected to the lock tongue rod 14. Pulling the lever 16 to one side can pull the lock tongue rod 14 out of the buckle hole 9 to achieve quick unlocking.

[0037] In this embodiment: When in use, rotate the door panel to dock the lock body 1 onto the buckle box 4. At this time, when one end of the lock tongue rod 14 contacts the buckle box 4 with its arc-shaped surface, it will contract inward. Then, after aligning with the buckle hole 9, it will pop out under the action of the second spring 15. The other end of the lock tongue rod 14 is flat, so it cannot be opened in the reverse direction to achieve self-locking.

[0038] After the locking tongue rod 14 is inserted into the keyhole 9, the inclined tongue assembly will unfold, and the small inclined tongue 17 will pop out under the action of the third spring 21. One end of the copper column 18 is inserted between the two leaf springs 19, squeezing the leaf springs 19 apart. At this time, the leaf springs 19, the copper column 18, and the contact 20 are in mutual contact, closing the circuit of the warning light 5. The warning light 5 is preferably a red light, which can prompt the user that the lock is normally locked. When the warning light 5 does not light up after the door is locked, it indicates that the device has a malfunction, and the locking tongue rod 14 and the inclined tongue assembly have not moved to the normal position and have not been correctly locked.

[0039] When the lock body 1 fits against one end of the buckle box 4, it will squeeze and trigger the switch 22, causing the trigger switch 22 to move inward to close the buzzer 6 circuit. At this time, if the warning light 5 does not light up normally, the buzzer 6 will be activated to warn the user.

[0040] When the device is installed outdoors, the photovoltaic panel 3 can charge the battery 2 to energize the warning light 5 and the buzzer 6.

[0041] The keyhole 8 can insert a key to rotate the lock cylinder 10. The lock cylinder 10 is inserted into the keyhole 9 to fix the device and prevent it from being quickly opened. Pulling the lever 16 to one side can pull the locking tongue rod 14 out of the keyhole 9 to achieve quick unlocking. Embodiment 2:
