Description

Technical Field

[0001] This application relates to the field of stationery, and in particular to a rotating pen. Background Technology

[0002] As a basic writing tool, the core function of a pen is to meet the user's writing needs. However, with increasing market competition and diversified consumer demands, especially among the main consumer group represented by students, their needs for pens have gone beyond basic writing fluency. They now demand more from products that are fun, interactive, and personalized. Consequently, many pen designs that enhance the user experience have emerged in the market.

[0003] Current rotary pens have a rotating part located in the pen barrel, connected to internal components via a screw-like engagement structure. When the trigger assembly is pressed, the rotating part rotates forward; when the trigger assembly is reset, the rotating part rotates in the reverse direction. Another design uses a ratchet and pawl mechanism at the junction of the rotating part and the pen barrel. When the trigger assembly is pressed, the ratchet and pawl mechanism drives the rotating part to rotate forward; when the trigger assembly is reset, the ratchet and pawl mechanism continues to rotate forward until the rotational kinetic energy is dissipated by the frictional resistance between the ratchet and pawl, at which point the rotation stops.

[0004] Both of the aforementioned rotary pens have limitations in their rotating component designs. Rotary pens with reversible rotating components cannot achieve instantaneous acceleration due to the limited stroke of the single press trigger component. Rotary pens with ratchet and pawl structures suffer from continuous energy loss due to frictional resistance between the ratchet and pawl, preventing high-speed rotation even with multiple presses. Therefore, the maximum rotational speed of existing rotating components is relatively low. When high-speed rotation is required to create more impressive effects with fluorescent suspension or light-emitting components, neither of these two rotary pen designs can meet the requirements. Summary of the Invention

[0005] In order to achieve a more dazzling effect by enabling high-speed rotation of rotating parts, this application provides a rotating pen.

[0006] This application provides a rotary pen, which adopts the following technical solution: A rotary pen includes a pen barrel, a press-triggered component, and a rotating component. The pen refill is located inside the pen barrel; The press trigger assembly is used to control the extension / retraction of the pen refill and the pen barrel. The press trigger assembly includes a ratchet seat connected to the upper end of the pen refill, a pawl seat located above the ratchet seat and cooperating with the ratchet seat, a press member and a connecting rod connected above the pawl seat, and a spring located between the lower end of the pen refill and the pen barrel. The outer side of the connecting rod is formed with a spiral protrusion. The rotating component is driven to rotate at high speed by the pressing trigger component. The rotating component includes a rotating seat sleeved on the upper end of the pen barrel, a rotating disk installed above the rotating seat, a rotating transmission component located on the inner side above the rotating disk, and a cover located on the outer side above the rotating disk. The rotating disk has a lower annular tooth formed on it, the rotating transmission component has a spiral through hole adapted to the spiral protrusion, and the lower side of the rotating transmission component has an upper annular tooth formed on it. When the pressing component is pressed down, the upper and lower ring teeth of the rotary transmission component abut against each other, and apply a lateral rotational force to the rotating disk when the rotary transmission component rotates; when the pressing component springs back upward, the rotary transmission component moves up to abut against the cover and rotates back to its original position, at which point the upper and lower ring teeth separate.

[0007] By adopting the above technical solution, when the pressing component is pressed down, the connecting rod drives the rotary transmission component downward, causing the upper and lower annular teeth to abut. During continued pressing, the spiral protrusion on the outer side of the connecting rod drives the rotary transmission component to rotate. Due to the engagement of the upper and lower annular teeth, the rotating disk rotates accordingly. When the pressing component is released, the pressing component and the connecting rod retract under the action of the spring. At this time, the rotary transmission component is driven to move upward synchronously, the upper and lower annular teeth separate, and the rotary transmission component moves upward to abut against the cover and rotates back to its original position. During this process, there is no significant friction between the rotary transmission component and the rotating disk, resulting in minimal energy loss. Therefore, by repeating the above process, high-speed rotation of the rotating disk can be achieved.

[0008] Preferably, at least three balls are embedded in a ring around the upper end face of the rotating seat, and the rotating transmission component includes a transmission sleeve and an upper end plate formed on the upper end of the transmission sleeve. The spiral through hole is located on the upper end plate, and at least three balls are embedded in a ring around the outer side of the spiral through hole on the upper end plate.

[0009] By adopting the above technical solution, the ball bearings set on the upper end face of the rotating seat ensure that there is no sliding friction between the rotating seat and the rotating disk when the rotating disk rotates at high speed. Instead, the rolling friction between the ball bearings and the rotating seat greatly reduces the frictional resistance, enabling the rotating disk to achieve high-speed rotation.

[0010] Preferably, both the lower and upper annular teeth include an inclined surface and a vertical surface, and the inclined and vertical surfaces of both are in contact with each other. When the pressing member presses down and the rotating transmission member is rotated, the vertical surface of the upper annular tooth and the vertical surface of the lower annular tooth abut against each other to apply force. When the pressing member stops pressing down, the inclined surface of the lower annular tooth abuts against the inclined surface of the upper annular tooth to apply force, causing the rotating transmission member to move upward until the lower annular tooth separates from the upper annular tooth.

[0011] By adopting the above technical solution, when the pressing component stops pressing down, the inclined surface of the lower annular tooth abuts against the inclined surface of the upper annular tooth, applying force to move the rotary transmission component upward until the lower annular tooth separates from the upper annular tooth. Even if the speed at which the spring drives the pressing component and connecting rod to return slows down, the lower and upper annular teeth can still quickly complete the separation, reducing frictional loss.

[0012] Preferably, the rotating disk includes a rotating sleeve fitted from top to bottom on a rotating seat. The outer side of the lower end of the rotating sleeve is formed with a butterfly-shaped transparent wheel. The transparent wheel has an annular receiving cavity formed inside. Vertical push plates are provided at intervals on the inner side wall of the receiving cavity near the center. Fluorescent suspension is provided inside the receiving cavity.

[0013] By adopting the above technical solution, when the rotating disk rotates, the fluorescent suspension also rotates under the drive of the push plate inside the rotating disk, and the rotation speed between the fluorescent suspension in the containment cavity and the rotating disk is different, forming a dreamy double-spinning luminous UFO shape.

[0014] Preferably, the rotating disk includes a rotating sleeve fitted onto a rotating seat from top to bottom. The outer side of the lower end of the rotating sleeve is formed with a butterfly-shaped transparent wheel. The transparent wheel has an annular receiving cavity formed inside. Vertical push plates are arranged at intervals in the receiving cavity. A strong magnet is fixed to the upper end of the ratchet seat. At least three sets of light-emitting components are arranged in the receiving cavity of the rotating disk. Each set of light-emitting components includes a coil and an LED bead. The LED bead is electrically connected to both ends of the coil.

[0015] By adopting the above technical solution, when the rotating part rotates at high speed during continuous pressing, the coil cuts the electromagnetic field of the strong magnet to generate current, which makes the LED light shine, forming a luminous UFO shape.

[0016] Preferably, the magnetic poles of the strong magnet are oriented left and right, the coil is spirally arranged between two push plates in the receiving cavity, and the two ends of the coil abut against the push plates. The receiving cavity has an LED bead groove formed on the side facing out of the rotating disk, and the LED bead is located in the LED bead groove.

[0017] By adopting the above technical solution, the push plate abuts against both ends of the coil, so that the coil can rotate synchronously with the rotating disk better, and the LED beads are set in the lamp bead slot so that the luminous effect can be more clearly seen through the rotating disk.

[0018] Preferably, the cover includes a shell sleeve and a shell end plate located at the upper end of the shell sleeve. The center of the shell end plate is formed with a through hole for the connecting rod to pass through. When the cover is snapped and fixed to the rotating disk, the distance between the shell end plate and the lower annular tooth is greater than the height of the rotating transmission component.

[0019] Preferably, the upper end face of the pawl seat is formed with an octagonal pawl engagement hole, the connecting rod is octagonal prism-shaped and the lower end is formed with a lower engagement block that slopes upwards and away from the center of the pressing member, the lower end of the connecting rod is formed with a lower deformation clearance hole that runs from front to back through the connecting rod, the small end of the lower engagement block is smaller than the pawl engagement hole and the large end is larger than the pawl engagement hole; the upper end of the connecting rod is formed with an upper engagement block that slopes downwards and away from the center of the connecting rod, the upper end of the connecting rod is formed with an upper deformation clearance hole that runs from front to back through the connecting rod, the lower side of the pressing member is formed with a pressing groove, and the bottom surface of the pressing groove is formed with an octagonal pressing engagement hole that mates with the upper engagement block.

[0020] By adopting the above technical solution, the connecting rod is connected to the pressing part and the pawl seat, and the three will not rotate relative to each other. When the pressing part is pressed, it can convert the external force into the kinetic energy of the rotating disk as much as possible.

[0021] Preferably, there are two spiral protrusions, which are distributed in a 180-degree rotation around the center of the connecting rod. The upper end face of the two spiral protrusions abuts against the inner side wall of the pressing groove of the pressing member, and the lower end face of the spiral protrusions abuts against the upper end face of the pawl seat.

[0022] By adopting the above technical solution, the structure in which the spiral protrusion abuts against the inner wall of the pressing groove and the upper end face of the pawl seat makes the positions of the connecting rod, the pressing part, and the pawl seat completely fixed relative to each other.

[0023] Preferably, the upper side of the ratchet seat and the lower side of the pawl seat are formed with matching ratchet teeth, a limiting break is formed between the ratchet teeth of the pawl seat, a limiting groove is formed on the side of the ratchet seat, the rotating seat is inserted and fixed to the pen barrel, and a limiting protrusion is formed on the inner side wall of the rotating seat in the up-down direction for cooperating with the limiting break and the limiting groove.

[0024] By adopting the above technical solution, when the pressing component is pressed once, the ratchet seat rotates to a state where the limiting protrusion is not aligned with the limiting groove, thus holding the pen refill in the extended pen barrel position and preventing it from retracting. When the pressing component is pressed again, the ratchet seat rotates to a state where the limiting protrusion is aligned with the limiting groove, allowing the pen refill to retract into the pen barrel.

[0025] In summary, this application includes at least one of the following beneficial technical effects: When the pressing component is pressed down, the connecting rod drives the rotary transmission component downward, causing the upper and lower annular teeth to engage. As the pressing continues, the spiral protrusion on the outer side of the connecting rod drives the rotary transmission component to rotate. The engagement of the upper and lower annular teeth causes the rotating disk to rotate accordingly. When the pressing component is released, the pressing component and connecting rod retract under the action of the spring. At this time, the rotary transmission component is driven to move upward synchronously, the upper and lower annular teeth separate, and the rotary transmission component moves upward to a position abutting against the cover and then rotates back to its original position. During this process, there is minimal friction between the rotary transmission component and the rotating disk, resulting in minimal energy loss. Therefore, by repeating the above process, high-speed rotation of the rotating disk can be achieved.

[0026] The ball bearings on the upper surface of the rotating base prevent sliding friction between the rotating base and the rotating disk when the rotating disk rotates at high speed. Instead, the rolling friction between the ball bearings and the rotating base significantly reduces frictional resistance, enabling the rotating disk to rotate at high speed.

[0027] When the pressing element stops pressing down, the inclined surface of the lower ring tooth abuts against the inclined surface of the upper ring tooth, applying force to move the rotating transmission element upward until the lower ring tooth separates from the upper ring tooth. Even if the speed at which the spring drives the pressing element and connecting rod to return slows down, the lower and upper ring teeth can still quickly complete the separation, reducing frictional loss.

[0030] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0031] This application discloses a rotating pen. The terms "up", "down", "left" and "right" used in the embodiments are schematic representations of relative directions and are not limitations on the positional relationship. Example

[0032] like Figure 1 and Figure 2 As shown, the rotary pen includes a pen barrel 1, a pen core 2 located inside the pen barrel 1, a press trigger assembly 3 for controlling the extension / retraction of the pen core 2 into the pen barrel 1, and a rotary assembly 4 driven by the press trigger assembly 3 to rotate at high speed.

[0033] like Figures 2 to 4As shown, the press-triggered assembly 3 includes a ratchet seat 5 connected to the upper end of the pen refill 2, a pawl seat 6 located above the ratchet seat 5 and cooperating with it, a pressing member 7 connected above the pawl seat 6, a connecting rod 8, and a spring 9 located between the lower end of the pen refill 2 and the pen barrel 1. The upper side of the ratchet seat 5 and the lower side of the pawl seat 6 are formed with mating ratchet teeth. A limiting break 10 is formed between the ratchet teeth of the pawl seat 6, and a limiting groove 11 is formed on the side of the ratchet seat 5. When pressed by the pressing member 7, the ratchet seat 5 is rotated relative to the ratchet seat, causing a change in the mating position of the ratchet seat 5 and the pawl seat 6, thereby controlling whether the pen refill 2 extends out of the pen barrel 1. The upper surface of the pawl seat 6 is formed with an octagonal pawl engagement hole 12. The connecting rod 8 is octagonal in shape and has a lower engagement block 13 at its lower end that slopes upwards and away from the center of the pressing member 7. The lower end of the connecting rod 8 has a lower deformation clearance hole 14 that passes through the connecting rod 8 from front to back. The smaller end of the lower engagement block 13 is smaller than the pawl engagement hole 12, and the larger end is larger than the pawl engagement hole 12. The lower engagement block 13 passes through the pawl engagement hole 12, thus connecting the connecting rod 8 and the pawl seat 6. The upper end of the connecting rod 8 has an upper engagement block 15 that slopes downwards and away from the center of the connecting rod 8. The upper end of the connecting rod 8 also has an upper deformation clearance hole 16 that passes through the connecting rod 8 from front to back. The lower side of the pressing component 7 has a pressing groove 17, and the bottom surface of the pressing groove 17 has an octagonal pressing engagement hole 44 that mates with the upper engagement block 15, thereby connecting the connecting rod 8 to the pressing component 7. The outer side of the connecting rod 8 has two right-handed spiral protrusions 18, which are identical in shape and size and rotate 180 degrees around the center of the connecting rod 8. The upper surfaces of the two spiral protrusions 18 abut against the inner wall of the pressing groove 17 of the pressing component 7, and the lower surfaces of the spiral protrusions 18 abut against the upper surface of the pawl seat 6. Therefore, the relative positions of the pawl seat 6, the connecting component, and the pressing component 7 are all fixed.

[0034] like Figure 5 and Figure 6 As shown, the rotating assembly 4 includes a rotating seat 19 sleeved on the upper end of the pen barrel 1, a rotating disk 20 mounted above the rotating seat 19, a rotating transmission component 21 located on the inner side above the rotating disk 20, and a cover 22 located on the outer side above the rotating disk 20. The rotating seat 19 is inserted and fixed to the pen barrel 1, and the inner sidewall of the rotating seat 19 is formed with a limiting protrusion 23 in the vertical direction. The limiting protrusion 23 cooperates with the limiting break 10 to prevent the ratchet seat 6 from rotating. When the pressing member 7 is pressed once, the ratchet seat 5 rotates to a state where the limiting protrusion 23 is not aligned with the limiting groove 11, and abuts against the ratchet seat 5 to keep the pen refill 2 in the extended state of the pen barrel 1 and prevent it from retracting. When the pressing member 7 is pressed again, the ratchet seat 5 rotates to a state where the limiting protrusion 23 is aligned with the limiting groove 11, and the pen refill 2 can retract into the pen barrel 1. At least three ball bearings 24 are embedded in a ring around the upper end surface of the rotating seat 19.

[0035] like Figure 5 and Figure 6 As shown, the rotating disk 20 includes a rotating sleeve 25 fitted onto a rotating base 19 from top to bottom. A butterfly-shaped transparent wheel 26 is formed on the outer side of the lower end of the rotating sleeve 25. An annular receiving cavity 27 is formed inside the transparent wheel 26. Vertical push plates 28 are spaced at intervals on the inner wall of the receiving cavity 27 near its center, with a distance between the push plates 28 and the inner wall of the receiving cavity 27 away from its center. From a top-down view, the push plates 28 are tilted counterclockwise away from the center of the rotating sleeve. A fluorescent suspension is disposed within the receiving cavity 27. An abutment ring 29 is formed inwardly at the upper end of the rotating sleeve 25, and the lower surface of the abutment ring 29 abuts against the ball bearing 24. A lower locking portion 30 extends upward from the outer ring of the upper surface of the abutment ring 29. The inner ring of the upper surface of the abutment platform 29 is formed with a ring of lower annular teeth 31, and in the cross-sectional view along the center line of the abutment platform, each lower annular tooth 31 includes an inclined surface and a vertical surface, with the inclined surface sloping upward from left to right.

[0036] like Figure 5 and Figure 6 As shown, the rotary transmission component 21 includes a transmission sleeve 32 and an upper end plate 33 formed on the upper end of the transmission sleeve 32. The lower end face of the transmission sleeve 32 is formed with upper annular teeth 34 that mate with the lower annular teeth 31. In a cross-sectional view of the center line of the transmission sleeve 32, each upper annular tooth 34 includes an inclined surface and a vertical surface, with the inclined surface sloping downwards from right to left. The upper end plate 33 is formed with a spiral through hole 43 that matches the spiral protrusion 18, and at least three ball bearings 24 are embedded in a ring around the outer side of the spiral through hole 43 on the upper end plate 33.

[0037] like Figure 5 and Figure 6 As shown, the housing 22 includes a housing sleeve 35 and a housing end plate 36 located at the upper end of the housing sleeve 35. The housing end plate 36 has a through hole formed in its center for the connecting rod 8 to pass through. The lower end of the inner side of the housing sleeve 35 has a snap-fit ​​protrusion 37 formed, which cooperates with the lower snap-fit ​​part 30. When the housing 22 is snapped and fixed to the rotating disk 20, the distance between the housing end plate 36 and the lower annular tooth 31 is greater than the height of the rotating transmission member 21.

[0038] Specific usage process: When the pressing component 7 is pressed down, the connecting rod 8 drives the rotary transmission component 21 to move downward, causing the upper annular tooth 34 and the lower annular tooth 31 to abut. During the continued pressing down, the spiral protrusion 18 on the outside of the connecting rod 8 drives the rotary transmission component 21 to rotate. Due to the cooperation of the upper annular tooth 34 and the lower annular tooth 31, the rotating disk 20 rotates accordingly. Under the drive of the push plate 28 inside the rotating disk 20, the fluorescent suspension also rotates.

[0039] When the pressing element 7 is released, the pressing element 7 and the connecting rod 8 retract under the action of the spring 9. At this time, the rotary transmission element 21 is driven to move upward synchronously, and the upper ring tooth 34 and the lower ring tooth 31 separate until the ball 24 of the rotary transmission element 21 abuts against the shell end plate 36. At this time, the connecting rod 8 continues to rise, and the rotary transmission element 21 is driven to rotate in the opposite direction. During this process, the rotating disk 20 continues to rotate in the original direction.

[0040] By repeatedly pressing and releasing the pressing part 7, the rotating disk 20 can be continuously accelerated. Due to the different rotation speeds between the fluorescent suspension in the receiving cavity 27 and the rotating disk 20, a dreamy double-spinning luminous UFO shape is formed. Example

[0041] like Figure 7 and Figure 8 As shown, the only difference between this embodiment and Embodiment 1 is that a strong magnet 38 is fixed to the upper end of the ratchet seat 5, and the magnetic poles of the strong magnet 38 are oriented left and right. At least three sets of light-emitting components 39 are disposed within the receiving cavity 27 of the rotating disk 20. Each set of light-emitting components 39 includes a coil 40 and an LED bead 41. The coil 40 is spirally disposed between two push plates 28 within the receiving cavity 27, and both ends of the coil 40 abut against the push plates 28. An LED bead groove 42 is formed on the side of the receiving cavity 27 facing outwards from the rotating disk 20. The LED bead 41 is located within the LED bead groove 42, and the LED bead 41 is electrically connected to both ends of the coil 40.

[0042] When the rotating part rotates at high speed during continuous pressing, the coil 40 cuts the electromagnetic field of the strong magnet 38 to generate current, which makes the LED light shine, forming a luminous UFO shape.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
