It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0026] As Figures 1 to 5 shown, this embodiment provides a locking structure for a magnetic lock tongue, which includes a housing 1, a lock tongue assembly 2, an unlocking lever 3, a locking member 4 and a lock core cam 5. A through first through hole 101 is provided on the housing 1. The lock core cam 5 is located in the first through hole 101. The locking member 4 is located on one side of the lock core cam 5. A convex portion 51 is provided on the lock core cam 5. A notch portion 401 that cooperates with the convex portion 51 is provided on the locking member 4. The convex portion 51 is embedded in the notch portion 401. By rotating the lock core cam 5, the locking member 4 is pushed to move up and down. The lock tongue assembly 2 and the unlocking lever 3 are hinged inside the housing 1. A first boss 41 is provided at the lower end of the locking member 4. When the locking member 4 moves upward, the unlocking lever 3 is pushed to rotate by the first boss 41. The unlocking lever 3 pushes the lock tongue assembly 2 to rotate so that the lock tongue assembly 2 retracts into the housing 1. A second boss 21 is provided at the lower end position of the lock tongue assembly 2. An extension portion 42 is provided on the locking member 4 in the direction of the lock tongue assembly 2. A third boss 43 is provided at the end of the extension portion 42. The second boss 21 and the third boss 43 are arranged opposite to each other and can abut against each other to limit the rotation of the lock tongue assembly 2. By rotating the lock core cam 5 to drive the locking member 4 to move up and down, the third boss 43 of the locking member 4 abuts against the second boss 21 of the lock tongue assembly 2, so that after the door is closed, the lock tongue assembly 2 will not pop out and remains in the housing 1, avoiding children from accidentally closing the door and locking it, and reducing potential safety hazards.

[0027] As an optional embodiment, a first card slot 402 is provided on the locking member 4. A first spring 44 is provided in the first card slot 402. The first spring 44 is a compression spring. A first retaining piece 102 is provided on the housing 1. The first retaining piece 102 serves as the force receiving point of the first spring 44 at the top. One end of the first spring 44 abuts against the first retaining piece 102 inside the housing 1, and the other end of the first spring 44 abuts against the locking member 4.

[0028] As an alternative embodiment, at least two guiding blocks 45 are provided on the locking member 4, and sliding grooves 103 corresponding to the guiding blocks 45 are provided on the outer shell 1. The guiding blocks 45 of the locking member 4 are arranged in the sliding grooves 103 to move up and down, so that the locking member 4 can move within a preset range in the outer shell 1.

[0029] As Figure 6 shown, a concave hole 410 is provided on the first boss 41, a ball component 46 is arranged in the concave hole 410, a positioning hole 105 corresponding to the ball component 46 is provided on the outer shell 1, the ball component 46 is snapped into the positioning hole 105, the ball component 46 includes a ball 461 and a second spring 462, the second spring 462 is located at the bottom of the concave hole 410. When the locking member 4 is pushed to the bottommost position, the ball component 46 is snapped into the positioning hole 105, so that the locking member 4 is kept in a state where the third boss 43 abuts against the second boss 21, thus preventing displacement.

[0030] As an alternative embodiment, a hinge post 22 is provided at the middle position of the locking tongue assembly 2. The locking tongue assembly 2 is hingedly connected to the outer shell 1 through the hinge post 22. The unlocking lever 3 pushes the lower part of the locking tongue assembly 2, causing the locking tongue assembly 2 to rotate clockwise, achieving the effect of opening the door with a key.

[0031] As an alternative embodiment, inwardly protruding limiting arcs 11 are provided at both sides inside the outer shell 1. The limiting arcs 11 are located at the front and rear sides of the locking tongue assembly 2. The limiting arcs 11 can reduce the friction area, enabling the locking tongue assembly 2 to protrude more precisely from the outer shell 1 and preventing jamming and inability to protrude.

[0032] As an alternative embodiment, a magnet is provided inside the locking tongue assembly 2, a second retaining piece 104 is provided at a position on one side of the outer shell 1 inside the locking tongue assembly 2, and a rubber pad 23 is provided at the rear side of the locking tongue assembly 2. When the locking tongue assembly 2 enters the outer shell 1, the rubber pad 23 touches the second retaining piece 104. The second retaining piece 104 is used to block the rotation of the locking tongue assembly 2. A rubber pad 23 is provided at the rear side of the locking tongue assembly 2. When the locking tongue assembly 2 enters the outer shell 1, the rubber pad 23 touches the second retaining piece 104. The rubber pad 23 can achieve a noise reduction effect.

[0033] As Figure 7 shown, when the magnetic lock is in a non-door-closed state and the locking tongue assembly 2 is inside the outer shell 1, when the lock core pick 5 is rotated counterclockwise to push the locking member 4 to the bottommost position, the second boss 21 is at the leftmost position, causing the third boss 43 of the locking member 4 to move downward to the right side of the second boss 21. In this way, the third boss 43 abuts against the second boss 21, preventing the locking tongue assembly 2 from rotating and achieving the locking state of the locking tongue assembly 2, where it cannot rotate.

[0034] The above embodiments are the preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited thereto. Any other changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model are equivalent replacement methods and are all included in the protection scope of the present utility model.
