Description

Technical Field

[0001] This invention belongs to the field of classroom equipment technology, specifically a unified storage and management rack for classroom mobile phones. Background Technology

[0002] With the rapid development of mobile internet technology, smartphones have become an indispensable tool in people's daily lives and studies. However, in classroom teaching scenarios, students carrying mobile phones has brought about a series of problems that urgently need to be solved. At present, most schools adopt the method of teachers verbally reminding students to keep their phones safe, but this management model has obvious defects. When students put their phones in desk drawers, backpacks, or other places, they are easily distracted by ringtones, vibrations, or message notifications, which can disrupt classroom order. Some students even secretly use their phones in class for entertainment, social activities, and other non-learning activities, which seriously affects learning efficiency and teaching quality.

[0003] Publication number CN216534480U discloses a mobile phone electronic device storage device for classroom student management, including a storage rack with several retractable storage boxes inside. The inner wall of each retractable storage box is connected to an anti-static cotton cloth layer, and a buffer plate is installed inside each retractable storage box. A buffer slider and a locking rod are connected to the lower part of the buffer plate and to one side of the outer wall of the retractable storage box. An adjustable storage rack is installed on one side of the storage rack, with several adjustable storage slots inside. A locking plate is connected to the upper end of the adjustable storage rack. The buffer plate, which provides elastic cushioning, can buffer the phone from sliding down as needed, preventing damage. The locking rod can be combined with a locking telescopic rod to achieve a locking purpose, thus enabling the device to be used.

[0004] However, the device cannot allow several students to access their phones simultaneously. With limited break time, students want to quickly access their phones to reply to messages, which limits the access efficiency of the storage device. Therefore, it is necessary to enable students to quickly access their phones through the device, and to group students' phones by marking them, allowing high-achieving group members to place their phones in better locations.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figures 1 to 12 As shown, this invention provides a unified mobile phone storage and management rack for classrooms, including a support leg 1, a support frame 2 fixed to the top of the support leg 1, a storage cylinder 3 rotatably connected to the outside of the support frame 2, a storage box 4 slidably connected inside the storage cylinder 3, a locking mechanism 5 installed inside the storage box 4, a storage mechanism 6 installed inside the storage box 4, a magnetic block 7 fixed to the outside of the storage box 4, two sets of gripping grooves 8 on the outside of the storage box 4, the gripping grooves 8 being symmetrically distributed about the central axis of the storage box 4, a slot 9 on the top of the storage box 4, an observation window 10 on the outside of the storage box 4, five sets of storage cylinders 3 arranged at equal intervals about the central axis of the support frame 2, and ten sets of storage boxes 4 arranged in a circular array about the central axis of the storage cylinders 3.

[0037] The above scheme employs a slot 9 that allows students to insert their name tags into storage boxes 4 and observe them through viewing windows 10 to identify their own phone's storage box 4. Storage cylinders 3 are color-coded from bottom to top, with colors ranging from bronze to silver to gold to purple to red, corresponding to Bronze, Silver, Gold, Diamond, and King ranks in a game. Students are divided into groups of ten, ensuring that the average score within each group is not too disparate, thus preventing large differences in average scores between groups. Members of each group can only place their phones according to their respective ranks, and members in the red zone are periodically rewarded. Because the average scores of each group are not too different, each group has a chance to reach the red zone. The entire device is placed next to the podium, allowing students to clearly observe their positions, thereby improving the learning enthusiasm of the students in the class.

[0038] like Figures 1 to 6 As shown, the locking mechanism 5 includes a first limiting block 501, a first return spring 502, and a pressing block 503. The first limiting block 501 is movably connected to the inside of the storage box 4. The first return spring 502 is fixed to the bottom end of the first limiting block 501. The pressing block 503 is movably connected to the inside of the storage cylinder 3. A second return spring 504 is sleeved on the outside of the pressing block 503. The outer wall of the first limiting block 501 is in contact with the inner wall of the storage box 4. The first limiting block 501 and the storage box 4 are slidably connected. The first return spring 502 is provided with... Two sets of first return springs 502 are symmetrically distributed about the central axis of the first limiting block 501. The first return springs 502 are used to squeeze the first limiting block 501 and keep it moving upward. The squeezing block 503 and the storage cylinder 3 are slidably connected. There are ten sets of squeezing blocks 503 and second return springs 504. The squeezing blocks 503 and second return springs 504 are arranged in a ring array about the central axis of the storage cylinder 3. The second return springs 504 are used to squeeze the squeezing blocks 503 and keep it moving upward.

[0039] Using the above solution: When it is necessary to remove the storage box 4 to store or retrieve the mobile phone, press the second reset spring 504, which will cause the second reset spring 504 to press the first limiting block 501 downward, thereby causing the first limiting block 501 to disengage from the locking connection with the storage tube 3. At this time, the student puts his / her finger into the gripping groove 8 to pull out the storage box 4. The pulling force is greater than the magnetic force used by the magnet 7 for positioning, so that the storage box 4 can be taken out, and then the mobile phone can be stored or retrieved.

[0040] like Figures 1 to 11As shown, the storage mechanism 6 includes a mobile phone storage compartment 601, a storage slot 602, and rubber granules 603. The mobile phone storage compartment 601 is movably connected to the inside of the storage box 4. The storage slot 602 is opened at the top of the mobile phone storage compartment 601. The rubber granules 603 are fixed inside the mobile phone storage compartment 601. A pull rod 604 is fixed at one end of the mobile phone storage compartment 601. An extension block 605 is fixed to the outside of the mobile phone storage compartment 601. The outer wall of the mobile phone storage compartment 601 is attached to the inner wall of the storage box 4. The mobile phone storage compartment 601 and the storage box 4 are slidably connected. Several sets of rubber granules 603 are provided. The rubber granules 603 are arranged at equal intervals about the central axis of the storage box 4. Two sets of extension blocks 605 are provided. The extension blocks 605 are symmetrically distributed about the central axis of the mobile phone storage compartment 601.

[0041] like Figures 1 to 11 As shown, a third return spring 606 is fixed to the outside of the extension block 605. The outer wall of the extension block 605 is attached to the inner wall of the storage box 4. The extension block 605 and the storage box 4 are slidably connected. Two sets of third return springs 606 are provided. The third return springs 606 are symmetrically distributed about the central axis of the extension block 605. The third return springs 606 are used to squeeze the extension block 605 and keep it moving outward. A support base 607 is fixed to the outside of the extension block 605. Two sets of support bases 607 are provided. The support bases 607 are symmetrically distributed about the central axis of the extension block 605. The diameter of the first limiting plate 609 is smaller than the diameter of the second limiting plate 610. The inner wall of the second limiting plate 610 is attached to the outer wall of the first connecting rod 608. The second limiting plate 610 and the first limiting plate 609 are slidably connected.

[0042] like Figures 1 to 11 As shown, a first connecting rod 608 is fixed to the outside of the support base 607, a first limiting plate 609 is fixed to the outside of the first connecting rod 608, and a second limiting plate 610 is sleeved on the outside of the first connecting rod 608. A limiting seat 611 is fixed inside the mobile phone storage compartment 601. A second connecting rod 612 is movably connected inside the limiting seat 611. A fourth return spring 613 is sleeved on the outside of the second connecting rod 612. A second limiting block 614 is fixed to the outside of the second connecting rod 612. There are two sets of second connecting rods 612. The second connecting rods 612 are symmetrically distributed about the central axis of the limiting seat 611. The outer wall of the second connecting rod 612 is attached to the inner wall of the limiting seat 611. The second connecting rod 612 and the limiting seat 611 are slidably connected. The fourth return spring 613 is used to squeeze the second connecting rod 612 and the second limiting block 614 and keep them moving inward. One end of the second limiting block 614 has an inclined surface.

[0043] Using the above scheme: After the student removes their corresponding storage box 4 from the storage cylinder 3, the pull rod 604 pulls the entire mobile phone storage compartment 601 outward, causing the second limiting plate 610 to move towards the second limiting block 614. This causes the second limiting plate 610 to press against the second limiting block 614, causing the second limiting block 614 to retract inward. After the second limiting plate 610 passes, the fourth return spring 613 resets the second limiting block 614 using its restoring force, and the second limiting block 614 lifts the second limiting plate 610, making the second limiting plate 610 and the first limiting plate 609 fit together. At this time, the restoring force of the third return spring 606 pulls the extension block 605 away from the connection limit of the limiting seat 611, causing the extension block 605 and the mobile phone storage compartment 601 to move towards the third return spring 609. The return spring 606 moves in the direction of return, exposing the storage slot 602. Students can then place their phones into the storage slot 602. The rubber granules 603 provide cushioning protection for the phones. After the phones are placed in, the phone storage compartment 601 is pulled again by the lever 604, causing the first limiting plate 609 to move towards the limiting seat 611. This causes the first limiting plate 609 to press against the second limiting block 614, which retracts inward. After the first limiting plate 609 passes, the fourth return spring 613 resets the second limiting block 614 using its restoring force. This limits the first limiting plate 609 and the extension block 605. The tension of the third return spring 606 ensures the stability of the limiting, thus completing the phone storage.

[0044] The working principle and usage of this invention are as follows: Students insert their name tags into the storage box 4 via slot 9 and observe through the viewing window 10 to determine which storage box 4 belongs to their phone. The storage cylinders 3 are color-coded from bottom to top, with colors ranging from bronze to silver to gold to purple to red, corresponding to the bronze, silver, gold, diamond, and king ranks in a game. Students are divided into groups of ten, ensuring that the average score within each group is not too disparate, thus preventing large differences in average scores between different groups. Members in the corresponding group can only place their phones according to their respective ranks. Members in the red zone are periodically rewarded. Because the average scores of each group are not too different, each group has a chance to reach the red zone. The device is placed next to the podium, allowing students to clearly observe their positions, thereby improving the learning enthusiasm of the students in the class.

[0045] Next, when it is necessary to take out the storage box 4 to store or retrieve the mobile phone, press the second reset spring 504, so that the second reset spring 504 presses the first limit block 501 downward, thereby causing the first limit block 501 to disengage from the locking connection with the storage tube 3. At this time, the student puts his finger into the gripping groove 8 to pull out the storage box 4. When the pulling force is greater than the magnetic force used by the magnetic block 7 for positioning, the storage box 4 can be taken out, and then the mobile phone can be stored or retrieved.

[0046] Finally, after the student removes their corresponding storage box 4 from the storage cylinder 3, the phone storage compartment 601 is pulled outward by the lever 604. This causes the second limiting plate 610 to move towards the second limiting block 614, resulting in the second limiting plate 610 pressing against the second limiting block 614. The second limiting block 614 then retracts inward. After the second limiting plate 610 passes, the fourth return spring 613 resets the second limiting block 614 using its restoring force. The second limiting block 614 then lifts the second limiting plate 610, causing it to fit against the first limiting plate 609. At this point, the restoring force of the third return spring 606 pulls the extension block 605 away from the connection limit of the limiting seat 611, causing the extension block 605 and the phone storage compartment 601 to move towards the third return spring. The return direction of 606 moves, exposing the storage slot 602. Students can then place their phones into the storage slot 602. The rubber granules 603 provide cushioning protection for the phones. After the phones are placed in, the phone storage compartment 601 is pulled again by the lever 604, causing the first limiting plate 609 to move towards the limiting seat 611. This causes the first limiting plate 609 to press against the second limiting block 614, which retracts inward. After the first limiting plate 609 passes, the fourth return spring 613 resets the second limiting block 614 using its restoring force. Thus, the second limiting block 614 limits the first limiting plate 609, thereby limiting the extension block 605. The tension of the third return spring 606 ensures the stability of the limiting, completing the phone storage.
