Technical Field
[0001] This application relates to the field of office supplies and stationery storage technology, and in particular to a rotating pen holder. Background Technology
[0002] Pen holders are common stationery storage tools used in daily office and study settings. Traditional pen holders are mostly fixed in structure, which makes them inconvenient to take out and put away. To improve the flexibility of pen holders, related technologies have designed them with a rotatable structure, allowing the main body of the holder to be rotatably connected to the base. However, due to the limitations of the rotating mechanical structure, current rotating pen holders have limited functionality, poor adaptability to different scenarios, and cannot meet the needs of users.
[0003] The above content is only used to assist in understanding the technical solution of the utility model and does not represent an admission that the above content is prior art. Utility Model Content
[0004] In view of the above problems, this utility model proposes a rotary pen holder, which aims to solve the technical problem of the single function of rotary pen holders.
[0005] To achieve the above objectives, the rotary pen holder proposed in this utility model includes a main body, a base, and a wire winding module;
[0006] The main body of the cylinder is rotatably connected to the base, and a wire hole is provided on the wall of the main body of the cylinder;
[0007] The wire winding module is installed inside the main body of the drum. The wire winding module includes a winding mechanism and a data cable. The data cable has a winding section and a connector that are connected to each other. The winding section is wound around the winding mechanism. The connector can extend out of the main body of the drum through the wire hole and can rotate relative to the base with the main body of the drum. The winding mechanism is configured to lock the winding section in the pulled-out position and to unlock the winding section for automatic winding or to allow the winding section to be pulled out by external force.
[0008] In one embodiment, the base is provided with an insertion port, and the rotary pen holder further includes a charging connector correspondingly disposed at the insertion port, the charging connector being electrically connected to the data cable; the winding mechanism is rotatably disposed within the main body of the pen holder.
[0009] In one embodiment, the rotary pen holder further includes a mounting bracket, which is fixedly connected to the bottom of the main body of the holder, and the wire winding module is rotatably disposed in the middle of the mounting bracket; the mounting bracket has a storage groove corresponding to the wire hole, and the connecting plug is embedded and fixed in the storage groove.
[0010] In one embodiment, the mounting bracket is provided with a magnetic suction element on the bottom wall of the corresponding storage slot, and the connecting plug is magnetically fixed in the storage slot.
[0011] In one embodiment, the cylinder body extends longitudinally, and one of the mounting bracket and the base is provided with a rotatable flange extending laterally, while the other is provided with a rotatable groove for the rotatable flange to be rotatably inserted.
[0012] In one embodiment, the mounting frame includes a main frame and a chassis fixedly connected to the bottom of the main frame. The main frame is fixedly connected to the cylinder body. Both the main frame and the chassis have through holes in their middle portions for the connecting wires of the charging connector and the data cable to pass through. The main frame has a rotation space surrounding the through holes, and the cable winding module is rotatably disposed within the rotation space. The rotation groove is formed between the periphery of the chassis and the main frame.
[0013] In one embodiment, the cylinder body has an upward-opening storage cavity and an installation cavity isolated below the storage cavity, and the mounting frame and the wire winding module are both installed in the installation cavity.
[0014] In one embodiment, the cylindrical body has an inner wall and an outer wall surrounding the outer perimeter of the inner wall. The inner wall encloses the cavity to form the storage cavity. An air duct is formed between the outer wall and the inner wall. An air outlet communicating with the air duct is provided on the outer wall. An air inlet communicating with the air duct is provided on the base. A fan is provided in the air duct to guide airflow from the air inlet into the air duct and out through the air outlet.
[0015] In one embodiment, the bottom surface of the base is provided with a fixing structure for fixing to the placement surface, and the fixing structure includes at least one of a suction cup, an adhesive part, and a magnetic part.
[0016] In one embodiment, the fixing structure includes a mounting ring, a plug portion fixedly disposed on the top surface of the mounting ring, and an adhesive portion fixedly disposed on the bottom surface of the mounting ring. The plug portion is inserted into the bottom of the base, and the adhesive portion protrudes from the bottom surface of the base.
[0017] This utility model relates to a rotating pen holder. The main body of the holder is rotatably connected to a base. A cable winding module is installed inside the main body, and a cable passage hole is provided on the wall of the main body, allowing the connector of the data cable to extend out of the main body. Compared to traditional pen holders that only have a single storage function, this application achieves the organic integration of stationery storage and device charging functions by integrating a cable winding module into the main body, which can rotate relative to the base. It also creates a synergistic effect between the data cable storage and the pen holder's rotation function. The winding mechanism ensures that the cable length can be adjusted as needed and automatically resets, allowing the data cable to adjust its position synchronously with the pen holder's rotation. The rotation of the pen holder provides a mechanical carrier for cable direction adjustment, and the coordinated design of the cable passage hole and winding mechanism eliminates the risk of cable tangling during rotation, while maintaining a tidy desktop space.

[0042] In existing technologies, pen holders, as stationery storage tools, generally suffer from limited functionality. While traditional rotary pen holders allow for convenient access to stationery by rotating the main body, they cannot meet the charging needs of electronic devices in modern office settings. Users need to carry additional charging cables, resulting in cluttered desktop space.
[0043] Based on this, the present invention proposes a rotating pen holder.
[0044] In this embodiment of the utility model, please refer to Figures 1 to 7The rotary pen holder includes a main body 100, a base 200, and a wire winding module 300. The main body 100 is rotatably connected to the base 200, and a wire hole 110 is provided on the wall of the main body 100. The wire winding module 300 is installed inside the main body 100 and includes a winding mechanism 310 and a data cable 320. The data cable 320 has a winding section 321 and a connector 322 that are connected to each other. The winding section 321 is wound around the winding mechanism 310, and the connector 322 can extend out of the main body 100 through the wire hole 110 and can rotate with the main body 100 relative to the base 200. The winding mechanism 310 is configured to lock the winding section 321 in the pulled-out position and to unlock the winding section 321 for automatic winding or to be pulled out by external force.
[0045] In this embodiment, the shape of the cylindrical body 100 can be varied. For example, the cylindrical body 100 can be roughly cylindrical, square, polygonal, or irregularly shaped. The specific shape of the cylindrical body 100 can be selected and designed according to actual needs, and no specific limitation is made here. The material of the cylindrical body 100 can be selected according to actual needs. For example, the cylindrical body 100 can be made of plastic, wood, metal, etc., and no specific limitation is made here. The cross-sectional shape of the base 200 can be the same as or different from the cross-sectional shape of the cylindrical body 100. Generally, in order to reduce the space occupied and maintain overall consistency, the cross-sectional shape of the base 200 can be approximately the same as the cross-sectional shape of the cylindrical body 100. The base 200 is used to provide a rotation support for the cylindrical body 100, so the height of the base 200 should be much smaller than the height of the cylindrical body 100 to avoid affecting the depth of the storage cavity 120 of the cylindrical body 100.
[0046] The cable winding module 300 includes a winding mechanism 310 and a data cable 320. The data cable 320 consists of a winding section 321 wound on the winding mechanism 310 and a connector 322 extending out of the main body 100. One end of the winding section 321 is fixedly connected to the winding mechanism 310, and the other end is connected to the connector 322. The winding section 321 is wound into a coil, and its length is selected according to actual needs. It is understood that the connector 322 can be a single connector, meaning the data cable 320 can be a single-plug data cable 320, or it can be two or more connectors, making the data cable 320 a multi-connector data cable 320. The connector 322 can be a Type-C or Lightning standard interface for electrical connection to external electronic devices.
[0047] The winding mechanism 310 has automatic winding and pull-out locking functions. Specifically, the winding mechanism 310 has a locked state and an unlocked state. In the unlocked state, the winding mechanism 310 releases the winding section 321, allowing the data cable 320 to be pulled out to the required length and automatically winding. In the locked state, the winding mechanism 310 locks the data cable 320, keeping it in the pulled-out position and preventing it from retracting. The structure for implementing the locked and unlocked states of the winding mechanism 310 can be varied. For example, the winding mechanism 310 can include a spring assembly and a ratchet locking device. The spring provides automatic winding force, and the ratchet mechanism locks the length when the data cable 320 is pulled out. The specific structure of the winding mechanism 310 can refer to existing designs and is not specifically limited here.
[0048] The cylinder body 100 and the base 200 form a rotatable connection structure. The rotatable connection structure between the cylinder body 100 and the base 200 can be achieved by an axial rotation mechanism or a longitudinal rotation mechanism. For example, a bearing assembly, a turntable connection structure, or a rotating ring and rotating groove matching structure can be used. Here, there is no specific limitation on the rotatable connection method between the cylinder body 100 and the base 200. It is only necessary to enable the cylinder body 100 to rotate relative to the base 200 around its center line.
[0049] By installing the cable winding module 300 inside the tube body 100 and providing a cable passage hole 110 on the tube wall of the tube body 100, the connector 322 of the data cable 320 can extend out of the tube body 100 through the cable passage hole 110. In this way, the connector 322 can rotate synchronously with the tube body 100. Compared with the method of setting both the cable winding module 300 and the cable passage hole 110 on the base 200, the position of the connector 322 of the data cable 320 can be adjusted synchronously with the rotation of the tube body 100. Users can use the connector 322 from all 360 degrees, which greatly improves the ease of use of the rotary pen holder with the data cable 320.
[0050] To shorten the cable length, the cable guide hole 110 should be positioned on the drum wall near the base 200. Optionally, the cable winding module 300 is positioned inside the drum body 100 corresponding to the cable guide hole 110, and the winding center of the winding section 321 is aligned with the rotation center of the drum body 100 to ensure that the data cable 320 does not become kinked during rotation. Specifically, when the user needs to charge, the connector 322 is pulled out from the cable guide hole 110 to the desired length, and the winding mechanism 310 automatically fixes the position of the data cable 320. The rotation of the drum body 100 causes the connector 322 to rotate synchronously, allowing the connector 322 to be adjusted 360 degrees. After use, the locking mechanism is released, and the winding mechanism 310 automatically retracts the data cable 320, returning the connector 322 to its storage position.
[0051] This utility model relates to a rotating pen holder. The main body 100 is rotatably connected to the base 200. A cable winding module 300 is installed inside the main body 100, and a cable passage hole 110 is provided on the wall of the main body 100, allowing the connector 322 of the data cable 320 to extend out of the main body 100 through the cable passage hole 110. Compared to traditional pen holders with only a single storage function, this application integrates the cable winding module 300 on the rotating main body 100 relative to the base 200, achieving an organic integration of stationery storage and device charging functions, expanding the functionality and usage scenarios of the rotating pen holder. Furthermore, the storage of the data cable 320 and the rotation function of the pen holder create a synergistic effect. The winding mechanism 310 ensures that the cable length is adjusted as needed and automatically resets, allowing the data cable 320 to adjust its position synchronously with the rotation of the pen holder. The rotation of the pen holder provides a mechanical carrier for cable direction adjustment, and the cooperative design of the cable passage hole 110 and the winding mechanism 310 eliminates the risk of cable tangling during rotation and maintains a clean desktop space.
[0052] In one embodiment, such as Figure 2 , Figure 3 and Figure 10 As shown, the base 200 is provided with an insertion port 210, and the rotating pen holder also includes a charging connector 400 correspondingly provided at the insertion port 210. The charging connector 400 is electrically connected to the data cable 320; the winding mechanism 310 is rotatably provided inside the body 100 of the pen holder.
[0053] In this embodiment, the socket 210 is used for inserting the charging connector 400. The charging connector 400 refers to the power supply interface fixed at the socket 210, which can be implemented using a USB-C or Lightning standard interface for power cord connection. It is understood that since the charging connector 400 needs to be electrically connected to a power source, users prefer to keep its position fixed during use to avoid pulling on the power cord. However, since the connector 322 of the data cable 320 needs to be electrically connected to an external electronic device, its position often needs to be changed during use; therefore, users prefer to be able to flexibly adjust the position of the connector 322. Therefore, by placing the charging connector 400 on the base 200 and the connector 322 of the data cable 320 on the main body 100, the main body 100 can simultaneously and flexibly adjust the position of the connector 322 of the data cable 320 relative to the base 200, while effectively preventing the charging connector 400 from moving. Thus, multi-directional adjustment of the data cable 320 is achieved without additional pulling on the power cord.
[0054] Specifically, the charging connector 400 forms an electrical connection path with the data cable 320 via a wire. When the power cable is electrically connected to the charging connector 400, the charging connector 400 can transmit electrical energy to the connector plug 322 of the data cable 320, thereby powering external devices electrically connected to the connector plug 322. By rotatably accommodating the winding mechanism 310 within the drum body 100, the drum body 100 rotates relative to the winding mechanism 310 rather than synchronously, thus preventing the electrical connection wires of the charging connector 400 and the data cable 320 from twisting or tangling and affecting the rotation of the drum body 100. Since the winding mechanism 310 can automatically wind up and be pulled out by external force, when the main body 100 rotates, the main body 100 will drive the connector 322 to rotate synchronously. The winding mechanism 310 automatically retracts or releases the winding section 321. The rotatable wire winding module 300 makes the winding and unwinding action of the data cable 320 linked with the rotation of the main body 100, avoiding cable interference or tangling, and making the electrical connection between the charging connector 400 and the data cable 320 more stable, thereby ensuring the stability of the charging function.
[0055] In one embodiment, please refer to Figure 1 , Figure 3 , Figure 4 , Figure 7 , Figure 14 The rotating pen holder also includes a mounting bracket 500, which is fixedly connected to the bottom of the main body 100. The wire winding module 300 is rotatably disposed in the middle of the mounting bracket 500. The mounting bracket 500 is provided with a storage groove 510 corresponding to the wire hole 110, and the connecting plug 322 is embedded and fixed in the storage groove 510.
[0056] In this embodiment, the mounting bracket 500 refers to a structure that provides rotational support for the wire winding module 300. Its function is to provide a stable mounting base for the wire winding module 300 and simultaneously achieve mechanical linkage between the drum body 100 and the wire winding module 300. The mounting bracket 500 can be made of metal or plastic. There are many ways to fix the mounting bracket 500 to the drum body 100. For example, the mounting bracket 500 can be connected to the bottom of the drum body 100 by screws or clips. The mounting bracket 500 can be hidden inside the drum body 100 or partially or completely exposed at the bottom of the drum body 100. To ensure overall appearance consistency, the mounting bracket 500 can optionally be hidden inside the drum body 100.
[0057] The receiving groove 510 is a recessed structure for accommodating the connector 322. Specifically, it can be a U-shaped or rectangular groove, with its opening aligned with the wire hole 110. The receiving groove 510 secures the connector 322 in a preset position, preventing it from protruding beyond the main body 100. The connector 322 can be fitted into the receiving groove 510 by matching its outer contour with the shape of the outer contour. The connector 322 is fixedly connected to the receiving groove 510 by constraint, preventing it from accidentally detaching. For example, a protrusion can be provided on the side wall of the connector to engage with the receiving groove 510, or the connector can be magnetically secured within the receiving groove 510. Understandably, the side wall of the storage slot 510 has a through hole for the cable of the data cable 320 to pass through. The through hole should be adapted to the cable or slightly larger than the cable, and the size of the through hole should be smaller than the size of the connector 322 in order to limit the connector 322 and prevent the connector 322 from retracting into the cylinder body 100 when the winding mechanism 310 winds the data cable 320.
[0058] Specifically, after the mounting bracket 500 is fixed to the bottom of the drum body 100, the wire winding module 300 is installed in its central rotation space 542. When the drum body 100 and the mounting bracket 500 rotate relative to the base 200, they also rotate synchronously relative to the winding mechanism 310. The drum body 100 drives the connector 322 to rotate synchronously to extend and retract the cable, and the wire winding module 300 maintains a balance between tension during winding and unwinding. When the connector 322 is not in use, it is retracted into the storage groove 510. The side wall of the storage groove 510 forms a wrapping limit on the connector 322 to prevent the cable from sagging or the connector 322 from being damaged by collision. When the connector needs to be removed, the user can pull it out by applying force outward along the storage groove 510. At this time, the wire winding module 300 automatically releases the winding section 321. When the connector returns to its original position, the storage groove 510 guides the connector to accurately reset, and the wire winding module 300 completes automatic winding.
[0059] Traditional rotary pen holders lack a dedicated storage structure, with the connector 322 typically hanging on the outside of the holder body 100, making it susceptible to damage from impacts or tangled wires. This solution addresses this by using a mounting bracket 500 with a storage slot 510 for the connector 322, resolving the issue of the connector 322 becoming scattered when not in use due to the lack of a fixing structure 600. Simultaneously, the storage slot 510 protects the connector interface from external impacts. The linkage design between the wire retraction / detraction process and the rotation of the holder body 100 further simplifies user operation, achieving a unified system of quick access to the connector 322 and automatic wire management.
[0060] Furthermore, such as Figure 3 , Figure 4 and Figure 11As shown, the mounting bracket 500 is provided with a magnetic component 520 on the bottom wall of the storage slot 510, and the connecting plug 322 is magnetically fixed in the storage slot 510.
[0061] The magnetic component 520 is a part that generates magnetic attraction, which can be implemented using a permanent magnet. Its function is to magnetically attract the connector 322, ensuring that the connector remains fixed within the storage slot 510. The magnetic component 520 can be embedded in the bottom wall of the storage slot 510, or the mounting bracket 500 can be located on the back of the bottom wall of the storage slot 510, as long as the connector 322 and the magnetic component 520 are in full contact to form a stable attraction.
[0062] Specifically, when the connector 322 is placed in the storage slot 510, the magnetic force generated by the magnetic component 520 allows the connector 322 to automatically align and adhere to the slot during storage, thus securing it within the slot 510. Since the magnetic component 520 is hidden inside the bottom wall, the storage slot 510 maintains its original spatial structure, avoiding interference with the storage of the connector 322. When it is necessary to remove the connector 322, only a pulling force sufficient to overcome the magnetic attraction is required to release it; the operation eliminates the need for complex mechanical unlocking actions, simplifying the placement and removal of the connector 322.
[0063] If the connector 322 is fixed in the storage slot 510 by mechanical snap-fit or friction engagement, repeated insertion and removal can easily cause wear on the snap-fit or a decrease in friction, leading to loosening or even detachment of the connector 322. This solution replaces the mechanical structure with magnetic fixation, avoiding wear caused by physical contact. At the same time, the magnetic force can remain stable over a long period of time, improving the reliability and service life of the connector 322.
[0064] In one embodiment, please refer to Figure 3-6 , Figure 12 As shown, the cylinder body 100 extends longitudinally, and one of the mounting bracket 500 and the base 200 is provided with a rotating flange 220 extending laterally, and the other is provided with a rotating groove 530 for the rotating flange 220 to be rotatably inserted.
[0065] In this embodiment, the longitudinally extending cylindrical body 100 refers to the cylindrical body 100 whose axial direction is parallel to the direction of gravity. Specifically, it can be implemented using a cylindrical or polygonal prism-shaped cylindrical body 100 structure, forming a stable main support structure through longitudinal extension. The rotating flange 220 refers to a ring-shaped structure extending laterally. The rotating groove 530 refers to a groove structure matching the shape of the rotating flange 220, specifically implemented using an annular groove or a segmented arc-shaped groove. The groove wall of the rotating groove 530 circumferentially wraps around the rotating flange 220, forming an axial limiting constraint.
[0066] Specifically, the lateral extension design of the rotating flange 220 and the rotating groove 530 causes the contact surface of the two to extend radially along the cylinder body 100, forming surface contact rather than point or line contact during rotation. When the cylinder body 100 is rotated by an external force, the sliding trajectory of the rotating flange 220 in the rotating groove 530 is restricted by the groove wall, preventing axial displacement and eliminating the shaking phenomenon caused by the gap when the cylinder body 100 rotates.
[0067] This design utilizes a laterally extending rotating flange 220 and rotating groove 530 structure to expand the contact surface to a planar contact between the two sides of the rotating flange 220 and the groove wall. This effectively disperses lateral loads during rotation, while the axial enclosure of the rotating flange 220 by the groove wall restricts displacement freedom, resulting in a more precise rotation trajectory. This application enhances the mechanical stability of the rotating pen holder's rotating structure, eliminates wobbling caused by gaps during rotation, improves the smoothness and positioning accuracy of rotational operation, keeps the pen holder stable during rotation, and avoids functional failures due to structural looseness.
[0068] Furthermore, please refer to the following: Figure 7 and Figure 13 The mounting frame 500 includes a main frame 540 and a chassis 550 fixedly connected to the bottom of the main frame 540. The main frame 540 is fixedly connected to the main body 100. Both the main frame 540 and the chassis 550 have through holes 541 in the middle for the connecting wires of the charging connector 400 and the data cable 320 to pass through. The main frame 540 has a rotation space 542 surrounding the through hole 541. The cable winding module 300 is rotatably disposed in the rotation space 542. A rotation groove 530 is formed between the periphery of the chassis 550 and the main frame 540.
[0069] The main frame 540 refers to the rigid frame structure used to fix the main body 100 of the support cylinder. It can be made by injection molding or metal stamping. Its function is to provide basic support and stability for the mounting bracket 500. The chassis 550 refers to the annular plate-shaped structure connected to the bottom of the main frame 540. It can be integrally molded with the same material as the main frame 540 or assembled separately. Its function is to cooperate with the main frame 540 to form a rotating groove 530 to accommodate the rotating flange 220 on the base 200. The cable hole 541 refers to the hollow channel that passes through the middle of the main frame 540 and the chassis 550. It can be made by circular or elliptical hole structure. Its function is to provide a through path for the connecting wires of the charging connector 400 and the data cable 320 to avoid bending or tangling.
[0070] The rotation space 542 refers to the annular cavity area surrounding the wire passage hole 541 inside the main frame 540. Specifically, it can be achieved by providing an annular boss or groove on the inner side of the main frame 540. Its function is to provide an independent rotation area for the wire winding module 300 to avoid mechanical interference with the mounting frame 500, and to provide positioning for the rotation of the winding mechanism 310. The rotation groove 530 formed by the periphery of the chassis 550 and the main frame 540, together with the rotating flange 220 of the base 200, constitutes a rotating pair. The radial displacement of the rotating flange 220 is limited by the annular groove, thereby maintaining axial stability when the drum body 100 rotates.
[0071] In one embodiment, such as Figure 3 , Figure 5 , Figure 7 and Figure 8 As shown, the main body 100 has an upward-opening storage cavity 120 and an installation cavity 130 isolated below the storage cavity 120. The mounting bracket 500 and the wire winding module 300 are both installed in the installation cavity 130.
[0072] In this embodiment, the storage cavity 120 refers to the upward-facing space formed on the upper part of the tube body 100, used to store stationery, with the opening direction facilitating direct access for the user. The mounting cavity 130 refers to an independent space located below and physically isolated from the storage cavity 120, used to accommodate the wire winding module 300 and the mounting bracket 500. Specifically, it can be achieved by setting a horizontal partition inside the tube body 100 to achieve upper and lower layering.
[0073] Specifically, the upward-facing opening of the storage cavity 120 conforms to users' habit of storing stationery vertically, without changing traditional usage methods. The mounting cavity 130 uses an isolation structure to confine the cable winding module 300 to the bottom area, preventing the data cable 320 winding module 300 from occupying stationery storage space. The mounting bracket 500 and the cable winding module 300 are centrally arranged within the mounting cavity 130, separating the functional modules from the storage area through a vertical layering method. This ensures the stable operation of the cable winding mechanism 310 while maintaining the complete volume of the storage cavity 120. This vertically isolated spatial layout allows the rotary pen holder to add a charging function without increasing the overall size or compressing the original storage capacity, optimizing the internal space utilization of the main body 100 and avoiding structural bulkiness due to functional expansion.
[0074] In another embodiment, please refer to Figure 14The cylinder body 100 has an inner wall 140 and an outer wall 150 surrounding the outer perimeter of the inner wall 140. The inner wall 140 encloses and forms a storage cavity 120. An air duct 160 is formed between the outer wall 150 and the inner wall 140. An air outlet 151 communicating with the air duct 160 is provided on the outer wall 150. An air inlet 230 communicating with the air duct 160 is provided on the base 200. A fan is provided in the air duct 160 to guide airflow from the air inlet 230 into the air duct 160 and blow it out from the air outlet 151.
[0075] In this embodiment, a double-layer cylindrical wall structure formed by injection molding can be used to form the inner wall 140 and the outer wall 150. The inner wall 140 refers to the longitudinally extending cylindrical structure inside the main body 100, which provides a closed space for the storage cavity 120 to accommodate stationery, while isolating it from the outer wall 150. The outer wall 150 refers to the cylindrical structure surrounding the inner wall 140, which can be implemented as an annular shell coaxially arranged with the inner wall 140. Its function is to define the annular path of the air duct 160 together with the inner wall 140, preventing airflow from interfering with the internal components of the mounting cavity 130. The air duct 160 refers to the annular cavity between the inner wall 140 and the outer wall 150. Specifically, the width of the air duct 160 can be formed by adjusting the distance between the two walls. The function of the air duct 160 is to provide a continuous flow space for airflow from the air inlet 230 to the air outlet 151. The air outlet 151 refers to the hole opened on the side wall of the outer wall 150. Specifically, it can be implemented by evenly distributed circular or strip-shaped openings or openings with grilles. Its function is to guide the airflow in the air duct 160 to the external environment of the pen holder. The air inlet 230 refers to the through hole opened on the surface of the base 200. The number of air inlets 230 can be set to one or multiple. Its function is to provide an external air inlet for the air duct 160.
[0076] The fan refers to a centrifugal or axial flow air supply device installed within the air duct 160. Specifically, it can be implemented using a micro DC motor driving the fan blades. Its function is to accelerate the air circulation speed within the air duct 160 through forced convection. In practice, a control main board is also installed inside the cylinder body 100. The control main board is electrically connected to the fan and the connector 322, and power is supplied to the connector 322 via an external power source, thereby powering the fan. Alternatively, a battery electrically connected to the control main board can be installed inside the cylinder body 100, which can also power the fan. This solution integrates a fan into the pen holder, giving it both a fan and airflow function. It achieves an organic integration of stationery storage, device charging, and fan functionality, expanding the functionality and usage scenarios of the rotating pen holder. It effectively reduces the space occupied by desktop tools, making the desktop space more tidy.
[0077] Specifically, the double-layer cylindrical body 100 structure formed by the inner wall 140 and the outer wall 150 physically isolates the housing cavity 120 from the air duct 160. When the fan starts, external air enters the air duct 160 through the air inlet 230 of the base 200, and carries away the heat generated by the electronic components in the mounting cavity 130 as it flows along the annular path. Finally, it is discharged through the air outlet 151 of the outer wall 150, thus achieving indirect heat dissipation for the components inside the mounting cavity 130.
[0078] Compared with existing technologies, traditional rotary pen holders only achieve rotation through mechanical structures, without integrating any active heat dissipation devices or fan functionality. This solution, while maintaining the rotatable nature of the pen holder body 100, innovatively embeds the air duct 160 into the pen holder body 100 through a double-wall structure, thus integrating fan functionality into the pen holder without the need for additional external heat dissipation components.
[0079] Furthermore, the air outlet 151 is located at the end of the outer wall 150 away from the base 200. A grille or guide plate is provided at the air outlet 151 to guide the airflow, making the fan's airflow more concentrated and gentle. Even further, multiple air inlets 230 are provided, spaced circumferentially around the base 200. This effectively increases the air intake area and improves air intake efficiency. In some embodiments, an air intake grille is provided at the bottom port of the cylinder body 100 to prevent external debris from entering the air duct 160 and affecting the fan operation.
[0080] In one embodiment, such as Figure 2 As shown, the bottom surface of the base 200 is provided with a fixing structure 600 for fixing to the placement surface. The fixing structure 600 includes at least one of a suction cup, an adhesive part 630, and a magnetic part.
[0081] The placement surface can be any surface where the pen holder needs to be placed, such as a tabletop, desktop, or floor. The suction cup is a component that achieves fixation through negative pressure adsorption; it can be made of silicone or rubber, and its edge forms a sealed space when in contact with the placement surface to generate adsorption force. The adhesive part 630 refers to the structure that uses adhesive materials to achieve fixation; it can be double-sided tape, a reusable adhesive layer, or a pressure-sensitive adhesive layer covering the bottom surface of the base 200. The magnetic part is a component that achieves fixation through magnetic attraction; it can be a permanent magnet or a magnet embedded in the bottom surface of the base 200, suitable for metal placement surfaces. By setting up the fixing structure 600 to fix the base 200 to the placement surface, the overall wobbling of the pen holder caused by displacement of the base 200 or rotation of the main body 100 can be prevented.
[0082] Specifically, when the main body 100 of the pen holder rotates, the fixing structure 600 between the base 200 and the placement surface maintains connection stability through different mechanisms. For example, on a smooth tabletop or glass surface, the suction cup is pressed to expel internal air, creating negative pressure adsorption; on a wooden or plastic surface, the adhesive part 630 directly adheres using an adhesive material; on a metal tabletop or stand, the magnetic part uses magnetic force for adsorption. The fixing structure 600 can be fixedly installed on the base 200 or detachably installed on the base 200.
[0083] Optionally, the fixing structure 600 is detachably mounted on the base 200. Traditional fixing methods typically use a single suction cup or magnetic structure, which is difficult to adapt to both smooth glass and rough wooden surfaces simultaneously. By making the fixing structure 600 detachable, different fixing methods for the pen holder can be achieved by replacing the fixing structure 600. In this way, the fixing structure 600 can be configured individually or in combination, and different fixing structures 600 can be selected according to the usage scenario. This achieves stable fixation of the rotating pen holder on tabletops of different materials such as glass, wood, and metal, thereby improving the product's flexibility of use and environmental adaptability.
[0084] In one embodiment, please refer to Figure 10 The fixing structure 600 includes a mounting ring 610, a plug-in portion 620 fixedly disposed on the top surface of the mounting ring 610, and an adhesive portion 630 fixedly disposed on the bottom surface of the mounting ring 610. The plug-in portion 620 is plugged into the bottom of the base 200, and the adhesive portion 630 protrudes from the bottom surface of the base 200.
[0085] The mounting ring 610 is an annular base that supports the insertion part 620 and the adhesive part 630, and can be injection molded from plastic or metal. As a supporting carrier, the mounting ring 610 ensures that the adhesive part 630 is evenly stressed. The insertion part 620 is a protruding structure that connects to the bottom of the base 200, and can be in the form of a protruding post or pin, used to mechanically fix the mounting ring 610 to the base 200. The number of insertion parts 620 can be designed according to actual needs. To improve connection stability, at least two insertion parts 620 are typically provided, and these at least two insertion parts 620 are evenly arranged around the circumference of the mounting ring 610. The adhesive part 630 is an adhesive material layer attached to the bottom surface of the mounting ring 610, and can be silicone or pressure-sensitive adhesive. Its protrusion from the bottom surface of the base 200 ensures contact with the placement surface.
[0086] Specifically, the insertion part 620 on the top surface of the mounting ring 610 is inserted into the pre-set slot at the bottom of the base 200, forming a rigid connection through insertion and locking; the adhesive part 630 on the bottom surface of the mounting ring 610 extends downward and beyond the bottom surface of the base 200. When the base 200 is placed on the table, the adhesive part 630 is deformed under pressure to conform to the concave and convex shapes of different material surfaces, while increasing the adhesion area to improve the fixing strength.
[0087] Traditional rotating pen holders typically rely on the weight of the base 200 or simple anti-slip pads for fixation, which can easily lead to displacement due to insufficient friction during rotation. In this design, the base 200 is fixed to the placement surface via an adhesive part 630, and the fixing structure 600 is inserted into the base 200. The combination of the insertion part 620 and the adhesive part 630 ensures reliable fixation between the base 200 and the mounting ring 610 through mechanical connection, while the self-adaptive deformation capability of the protruding adhesive part 630 allows compatibility with various surface materials, solving the problems of insufficient adhesion and poor adaptability in traditional solutions. While maintaining a stable connection between the base 200 and the placement surface, no additional user adjustments to the fixing method are required. Furthermore, by allowing the fixing structure 600 to be inserted into the base 200, the user can pull out the entire pen holder body 100 and base 200 for movement when needed, making it more flexible and convenient. In addition, the fixing structure 600 can be flexibly selected according to the material of the placement surface, avoiding the shortcomings of insufficient adaptability of a single fixing method, and simplifying the installation and disassembly process.
