AI Technical Summary
The existing storage box lock body structure has a large volume due to the large space occupied by the lever structure between the motor and the anti-lock tongue, which limits the scope of application.
A spring-driven lock tongue reset structure is adopted, and the lever between the motor and the anti-lock tongue is eliminated. The motor drives the eccentric wheel to push the lever, and the spring reset mechanism of the lock tongue and lock hook is combined to achieve a snap-on connection between the lock tongue and lock hook.
The lock body structure is simplified and miniaturized, the occupied space is reduced, and the compactness of the lock body is improved.

Abstract
Description
Technical Field
[0001] The utility model relates to a lock body structure of a storage box, belonging to the technical field of locks. Background Art
[0002] Currently, people are increasingly demanding storage boxes due to their daily needs. However, in the fast-paced modern world, many users need to frequently access certain items, such as stationery, cosmetics, and tools. To protect safety and privacy, most storage boxes are equipped with locks. Currently, electronic locks that can be opened via a motor and a lock hook typically have a lever between the motor and the anti-lock tongue to move the anti-lock tongue. This lever requires a large installation space within the lock body, and the motor, lever, and anti-lock tongue are arranged relatively loosely within the lock body. This results in a larger electronic lock body, limiting its widespread application.
[0003] Therefore, how to provide a lock body structure of a storage box with a simple structure and no need for a reverse lock tongue is the research purpose of the present utility model. Utility Model Content
[0004] In view of the deficiencies of the above-mentioned technology, the present invention provides a lock body structure for a storage box, in which the lock tongue is reset by a spring, and there is no need to set a lever structure between the motor and the anti-lock tongue, making the lock body structure simpler and more compact.
[0005] In order to solve the existing technical problems, the technical solution adopted by the utility model is:
[0006] A lock body structure of a storage box, characterized in that it comprises a base plate, a motor, a lever, a lock tongue and a lock hook, wherein a lock slot is provided on the base plate, the lever is movably arranged on the base plate by a pin, the motor is fixedly arranged on one side of the base plate and pushes the lever to move by an eccentric wheel, the lock tongue is rotatably arranged on the base plate by a pin, a lock tongue spring for toggling the lock tongue to reset is provided between the lock tongue and the base plate, the lock hook is rotatably provided on the base plate by a pin and is arranged across the lock slot, a lock hook spring is provided between the lock hook and the base plate for toggling the lock hook to open, and when locked, one end of the lock tongue is connected to the lock hook buckle, and the other end is provided on one side of the lever.
[0007] Furthermore, a first limiting column and a second limiting column are provided on the bottom plate. The first limiting column is provided on a side of the lock tongue close to the shift rod, and the second limiting column is provided on the bottom side of the lock hook.
[0008] Furthermore, the lock tongue spring is sleeved on the pin of the lock tongue, one end of the lock tongue is snap-connected to the end of the lock tongue close to the lock hook, and the other end is pressed against the first limiting column.
[0009] Furthermore, the lock hook spring is sleeved on the pin of the lock hook, one end of the lock hook is snap-connected to the end of the lock hook close to the outer side of the lock slot, and the other end is pressed against the second limiting column.
[0010] Furthermore, the lock hook includes a first transverse hook and a second transverse hook that are integrally arranged. The first transverse hook and the second transverse hook are arranged in an F shape on the lock hook, and the second transverse hook is buckled with the lock tongue.
[0011] The beneficial effect of the utility model is that the lock tongue is reset by the spring, and there is no need to set a lever structure between the motor and the counter lock tongue, so that the lock body structure is simpler and more compact. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make those skilled in the art better understand the technical solution of the present invention, Figure 1-4 Further analysis of this utility model is made.
[0018] like Figure 1-4 As shown, a lock body structure of a storage box is characterized in that it includes a base plate 1, a motor 2, a driving rod 3, a locking tongue 4 and a locking hook 5. A locking slot 6 is provided on the base plate 1, the driving rod 3 is movably provided on the base plate 1 through a pin, the motor 2 is fixedly provided on one side of the base plate 1, and pushes the driving rod 3 to move through an eccentric wheel, the locking tongue 4 is rotatably provided on the base plate 1 through a pin, a locking tongue spring 7 for toggling the locking tongue 4 to reset is provided between the locking tongue 4 and the base plate 1, the locking hook 5 is rotatably provided on the base plate 1 through a pin, and is arranged across the locking slot 6, a locking hook spring 8 for toggling the locking hook 5 to open is provided between the locking hook 5 and the base plate 1, when locked, one end of the locking tongue 4 is snap-connected with the locking hook 5, and the other end is provided on one side of the driving rod 3.
[0019] In this embodiment, preferably, a first limiting column 9 and a second limiting column 10 are further provided on the base plate 1 , the first limiting column 9 is provided on the side of the lock tongue 4 close to the lever 3 , and the second limiting column 10 is provided on the bottom side of the lock hook 5 .
[0020] In this embodiment, preferably, the lock tongue spring 7 is sleeved on the pin of the lock tongue 4 , one end of which is snap-connected with the end of the lock tongue 4 close to the lock hook 5 , and the other end is pressed against the first limiting column 9 .
[0021] In this embodiment, preferably, the lock hook spring 8 is sleeved on the pin of the lock hook 5 , with one end being snap-connected to the end of the lock hook 5 close to the outer side of the lock slot 6 , and the other end being pressed against the second limiting column 10 .
[0022] In this embodiment, preferably, the lock hook 5 includes an integrally arranged first transverse hook 501 and a second transverse hook 502 , wherein the first transverse hook 501 and the second transverse hook 502 are arranged in an F shape on the lock hook 5 , and the second transverse hook 502 is snap-connected with the lock tongue 4 .
[0023] When the utility model is used: when unlocking, the motor 2 drives the eccentric wheel to rotate, driving the shift lever 3 to move, and the shift lever 3 pushes the lock tongue 4 to rotate, so that the lock tongue 4 is separated from the snap connection of the lock hook 5. The lock hook 5 is opened upward under the action of the lock hook spring 8, so that the lock catch on the box lid can be withdrawn from the lock groove 6, thereby opening the box lid of the storage box; when locking, the lock catch on the box lid is pressed and inserted into the lock groove 6, and the lock catch pushes the second horizontal hook 502 of the lock hook 5 to rotate downward, so that the first horizontal hook 501 of the lock hook 5 is locked to the lock catch, so that the lock catch cannot be withdrawn from the lock groove 6. At the same time, the motor 2 drives the shift lever 3 to reset, and the lock tongue 4 is reset under the action of the lock tongue spring 7, snap-connected with the second horizontal hook 502 of the lock hook 5, and locked. The utility model resets the lock tongue 4 by the spring, and does not need to set a shift lever structure between the motor and the anti-lock tongue, making the lock body structure simpler and more compact.
