Description

Technical Field

[0001] This utility model relates to a rotating storage device for teaching supplies. Background Technology

[0002] With the overall improvement of living standards and teaching standards, junior and senior high school students have a large number of textbooks and various learning supplies and tools. In order to facilitate storage, not occupy too much desk space, reduce the amount of things students carry, and lighten the burden on students, and to make it convenient for students to access or store these items at any time, many schools have purchased storage cabinets for storing learning supplies and tools in corners of classrooms or outside classrooms. Currently, most of these are ordinary wooden or metal cabinets, which are assembled into strips and stacked, occupying a lot of corridor length, affecting passage, and often causing accidental collisions, resulting in injuries to teachers and students, and causing unnecessary medical accidents and disputes. Utility Model Content

[0003] The purpose of this invention is to provide a convenient teaching supplies storage device that occupies a short length and can be placed in various locations (such as corners, the side of a podium, or the corner of a pillar).

[0004] To achieve the above objectives, this utility model provides a rotating storage device for teaching supplies, including a base and a central column;

[0005] The base is composed of multiple concentric sector-shaped parts, the central ends of which are fitted onto a concentric ring;

[0006] The top of the base is provided with a multi-layer storage cabinet group, which is composed of multiple single cabinets with the same cross-section as the concentric sector component, and the central end of each single cabinet is fitted onto a concentric cylinder.

[0007] The upper and lower cabinets, which are stacked together, slide relative to each other through multiple ball bearings installed on the bottom surface of the upper cabinet or the top surface of the lower cabinet.

[0008] The bottom surface of the lowest single cabinet is equipped with a supporting ball bearing that slides relative to the top surface of the concentric sector component.

[0009] The concentric ring and concentric cylinder are connected to the first bearing and the second bearing fixed on the central column by a plurality of first and second connecting rods that are evenly distributed around the circumference.

[0010] The beneficial effects of this utility model are: the whole is cylindrical, occupying a small length, and can be flexibly placed in corners, corners, column corners and other places where it does not usually occupy too much effective passage area, which can significantly reduce or reduce the impact on other people and the occurrence of accidental collisions, thus improving the safety of use; multiple cabinets are stacked one on top of the other, and each individual cabinet can rotate within a set range, effectively increasing the number of cabinets per unit area and expanding the usable space.

[0011] The present invention will be further described in detail below with reference to the accompanying drawings. Attached Figure Description

[0018] To further illustrate the technical means and effects of this utility model in achieving its intended purpose, the following detailed description of the specific implementation methods, structural features, and effects of this utility model is provided in conjunction with the accompanying drawings and embodiments.

[0019] To overcome the problems described in the background art, which involve using wooden or metal cabinets, assembling them into long, stacked sections, and occupying long corridors (inevitably narrowing these corridors and hindering passage; therefore, the length of the occupied corridor should be minimized to ensure the width of the corridor is not obstructed), thus affecting normal passage, especially during busy breaks between classes, which further impedes the passage of teachers and students, frequently leading to accidental collisions, injuries, and unnecessary medical accidents and disputes, this embodiment provides a... Figure 1 The illustrated teaching supplies storage device is small in size and can be placed in various locations (such as corners, the side of a podium, or the corner of a pillar), making it convenient to use. This rotating storage device includes a base 1 and a central column 2; wherein the base 1 consists of multiple... Figure 2The concentric sector-shaped components 3 shown are assembled, with their central ends fitted onto a concentric ring 4. The concentric ring 4 is connected to a first bearing 14 fixed on a central column 2 via multiple circumferentially distributed first connecting rods 12. With the aid of the first bearing 14 and the concentric ring 4, the concentric sector-shaped components 3 can rotate circumferentially around the central column 2, allowing the cabinet to rotate in place for easy access to books and teaching aids. Specifically, the supporting structure includes a multi-layer storage cabinet group 5 mounted on the top of the base 1, consisting of multiple... Figure 3 The single cabinet 6 shown has a cross-section consistent with the concentric sector 3. The central end of each single cabinet 6 is fitted onto a concentric cylinder 7. The concentric cylinder 7 is connected to a second bearing 15 fixed on the central column 2 by a plurality of circumferentially evenly distributed second connecting rods 13. The upper single cabinet 8 and the lower single cabinet 9 stacked together slide relative to each other through a plurality of ball bearings 10 installed on the bottom surface of the upper single cabinet 8 or the top surface of the lower single cabinet 9. The bottom single cabinet (such as...) Figure 1 The lower cabinet 9 shown is... Figure 1 The bottom single cabinet shown has a supporting ball bearing 12 installed on its bottom surface, which slides relative to the top surface of the concentric sector component 3. Through the above rotatable components such as the first bearing 14, the second bearing 15, the ball bearing 10, and the supporting ball bearing 12, the concentric sector component 3 and the single cabinet 6 can rotate around the central column 2, thus realizing the rotation of the cabinet. This allows the individual bookshelves to be found by rotating the cabinet in place, making it convenient to take out and put in books.

[0020] As can be seen from the above structural description, the storage device provided in this embodiment is cylindrical with multiple layers of cabinets stacked on top of each other, and each layer can rotate circumferentially, occupying little space. In particular, it can be placed in spaces that are rarely used, such as corners, column corners, and bends, greatly reducing the length of effective passageways occupied. More importantly, the whole is cylindrical and can rotate. In the event of an accidental collision, there are no sharp edges that can cause injury. Furthermore, the force can be dissipated by rotation, reducing or weakening the impact force on the human body, thus achieving effective protection for the human body.

[0021] To improve overall stability, a support disc 16 is installed at the bottom of the central column 2 in this embodiment. At least two rings of balls 17, evenly arranged circumferentially around the top of the support disc 16, are installed to match the ball grooves (not shown, but common grooves that can accommodate the balls and allow them to rotate within them) on the bottom surface of the concentric sector 3. The support disc 16 can be filled with cement to increase counterweight and improve stability.

[0022] Finally, to improve overall balance, this embodiment connects adjacent concentric sector-shaped components 3 and adjacent single cabinets 6 via magnetic buckle straps on the sides. These magnetic buckle straps consist of a woven strap 19 with one end fixed to the concentric sector-shaped component 3 or single cabinet 6 and the other end fixed to a magnet 18. This connects adjacent single cabinets, improving overall stability. In use, the magnetic buckle can be manually opened.

[0023] Finally, it should be noted that, to ensure the safety of the load-bearing cabinets, this embodiment has a [feature / equipment] installed on the top surface of the lower cabinet 9 or the bottom surface of the upper cabinet 8. Figure 4 The ball bearing retainer 20 shown is used to limit the relative sliding boundary between the upper cabinet 8 and the lower cabinet 9, ensuring that the upper cabinet 8 and the lower cabinet 9 are always stacked and supported together. The specific setting position can be adjusted according to the design parameters. The ball bearing retainer 20 can be set on the center line or at one-third of the arc position, depending on the proportion of the upper cabinet that is allowed to be suspended and the support force and structural stability provided by the lower cabinet and other supporting structures.

[0024] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention; however, it should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention; all such deductions or substitutions should be considered to fall within the protection scope of the present invention.

[0025] It should be noted that, to ensure the safety of the load-bearing cabinet, this embodiment has a [feature / equipment] installed on the top surface of the lower cabinet 9 or the bottom surface of the upper cabinet 8. Figure 4 The ball bearing retainer 20 shown is used to limit the relative sliding boundary between the upper cabinet 8 and the lower cabinet 9, ensuring that the upper cabinet 8 and the lower cabinet 9 are always stacked and supported together. The specific setting position can be adjusted according to the design parameters. The ball bearing retainer 20 can be set on the center line or at one-third of the arc position, depending on the proportion of the upper cabinet that is allowed to be suspended and the support force and structural stability provided by the lower cabinet and other supporting structures.
