Description

Technical Field

[0001] The utility model relates to the technical field of magnetic pencil cases, in particular to a magnetic pencil case. Background Art

[0002] Magnetic pencil cases typically utilize the attractive force of magnetic strips or magnets to open and close. When designing a magnetic pencil case, the strips or magnets can be placed on the lid and the case itself. When the lid is closed, the strips or magnets attract each other, ensuring the pencil case is tightly sealed. To open the pencil case, applying a certain amount of force overcomes the magnetic force, allowing the case to open.

[0003] Most existing magnetic pencil cases adopt a single-layer design in terms of space utilization, which may lead to insufficient space and fail to meet the needs of most users. Secondly, when fixing the internal pens, most of them use plastic pen caps, which is not easy to fix pens of uneven thickness. Therefore, a magnetic pencil case is proposed.

[0004] A magnetic pencil case disclosed in announcement number CN218832174U comprises a hinged box body and a lid, the lid being provided with a lock catch, the box body being provided with a lock tongue, the box body being further provided with a push-pull electromagnet, and a control assembly being electrically connected to the push-pull electromagnet; a push spring and a shaft sleeve being sleeved on the telescopic shaft of the push-pull electromagnet, the shaft sleeve being provided with a slot, the lock tongue being provided with a plug plate that is inserted into the slot, and the push-pull electromagnet being able to drive the lock tongue to lock and release the lock catch. The utility model uses a push-pull electromagnet to drive the lock tongue to move, thereby locking and releasing the lock catch, and its response is more sensitive and reliable than that of the prior art.

[0005] Although the above patent achieves the goal of driving the lock tongue to move by a push-pull electromagnet to lock and release the lock, and its response is more sensitive and reliable than the existing technology; however, the device relies on the internal inherent space for storage, the storage space is limited, and there are many types of stationery, which are mixed together and placed inside the pencil case, making it inconvenient to find.

[0006] Therefore, it is necessary to invent a magnetic pencil case to solve the above problems. Utility Model Content
