Description

Technical Field

[0001] This utility model relates to the technical field of writing instruments, and in particular to a plucked pen. Background Technology

[0002] Traditional push-button pens typically rely on a button located at the top of the pen barrel. The user's thumb applies axial pressure, driving an internal ratchet and latch mechanism to extend and retract the pen tip. However, in situations involving movement, bumps (such as driving or walking), or hand inconvenience, users find it difficult to maintain a stable grip and accurately align and press the small button. Furthermore, when the pen is subjected to lateral impact or pressure (such as an accidental drop), the internal plastic latch is easily broken or the ratchet teeth are damaged, causing the entire push-button system to malfunction and resulting in insufficient product durability. Utility Model Content

[0003] To overcome the technical problem in existing technologies where the button at the top of the pen can only be pressed along the pen's axis, easily damaging the internal mechanism of the pen upon lateral impact or pressure, this utility model provides a toggle pen, including a pen barrel and a pen refill disposed within the inner cavity of the pen barrel, and further including: a driving member rotatably disposed at the top of the pen barrel; and a transmission member disposed between the driving member and the pen refill; the rotation axis of the driving member coincides with or is parallel to the axis of symmetry of the pen barrel, the driving member is connected to the transmission member, and the driving member has a first position and a second position relative to the transmission member; when the driving member is in the first position, it drives the transmission member to move towards the bottom of the pen barrel, and the pen refill extends from the bottom of the pen barrel; when the driving member is in the second position, it drives the transmission member to reset, and the pen retracts into the pen barrel.

[0004] Furthermore, the driving component includes a first guide structure and a first limiting structure, wherein the first limiting structure is located on both sides of the first guide structure; The transmission component includes a second limiting structure; The first guide structure of the drive member located in the second position is rotatable about the axis of the drive member itself; the first limiting structure of the drive member located in the first position is engaged with the second limiting structure.

[0005] Furthermore, the first guide structure has a receiving cavity, and the first guide structure includes a plurality of inclined steps connected in sequence, the inclined steps being disposed on the inner surface of the receiving cavity; the second limiting structure is located at the top of the transmission member, and at least a portion of the second limiting structure is accommodated in the receiving cavity at the second position; the second limiting structure is a protrusion, the protrusion including a top edge, the two side walls of the top edge being arc-shaped transitions, and the plurality of inclined steps being able to rotate relative to the top edge.

[0006] Furthermore, the first limiting structure is a slot, the slot including a guide slope, the guide slope being connected and transitioning to the slope step; The slot of the drive member located in the first position engages with the protrusion; the slot of the drive member located in the second position separates from the protrusion, and the protrusion slides along the guide ramp onto the ramp step.

[0007] Furthermore, the first guide structure is a spherical structure or a hemispherical structure.

[0008] Furthermore, it also includes a cap, which is connected to the pen barrel. The cap has a mounting cavity and an opening. The mounting cavity communicates with the inner cavity of the pen barrel, and the opening communicates with the mounting cavity. The opening extends axially along the top of the cap. The drive unit also includes an operating part. The end of the drive unit away from the operating part and the transmission member are both located in the mounting cavity. The operating part extends out of the opening and is used to operate the drive unit to move along the length direction of the opening.

[0009] Furthermore, the operating part has a cylindrical structure.

[0010] Furthermore, the end of the mounting cavity away from the opening is a square cavity, and the bottom of the transmission component is a square structure, with the bottom of the transmission component being adaptably slidably disposed in the square cavity.

[0011] Furthermore, it also includes a return spring, the inner cavity of the pen barrel has an annular stepped surface, the pen refill is axially movable and passes through the pen barrel, the return spring is sleeved on the tail end of the pen refill, the stepped surface is located at the bottom of the pen barrel, and the return spring is located between the pen refill and the stepped surface.

[0012] Beneficial effects: The beneficial effects of adopting the technical solution of this utility model are as follows: 1) The drive unit is connected to the pen refill through the transmission unit. The drive unit can rotate freely in any direction on the pen barrel, thereby driving the transmission unit to move and making the pen refill move. Users only need to rotate the drive unit with one hand to extend and retract the pen refill, completely avoiding the axial pressing operation required in traditional designs.

[0013] 2) The position of the pen tip can be precisely controlled by simply rotating the drive from the first position to the second position, or from the second position to the first position. This simple rotational movement completely eliminates the reliance on precise axial pressing and allows for easy operation even in bumpy environments or when holding the pen with one hand.

[0014] 3) The driving component acts directly on the transmission component, replacing the easily damaged plastic latches and ratchet structure inside the transmission pen, resulting in stronger overall integrity and significantly improved impact resistance and durability; it is ergonomic, allowing precise control of the pen tip position through simple rotation.

[0015] 4) The first guide structure of the driving component can rotate arbitrarily along its own axis. During the rotation, the first limiting structure located on both sides of the first guide structure can be circumferentially locked with the second limiting structure, realizing the rotational movement of the driving component between the first position and the second position. The force flow path is short and symmetrical, and the entire mechanism is subjected to balanced force, which can effectively counteract the torque generated by the force on one side, fundamentally eliminating the possibility of backlash and relative sliding in the transmission process.

[0016] 5) The guide ramp can smoothly guide the protrusion to the correct engagement position in the slot, which can buffer the impact of collision. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0021] Please refer to Figures 1 to 8 A swivel pen includes a pen barrel 1 and a pen refill 2 disposed within the inner cavity of the pen barrel 1. It further includes: a drive member 3 rotatably disposed at the top of the pen barrel 1; and a transmission member 4 disposed between the drive member 3 and the pen refill 2. The rotation axis of the drive member 3 coincides with or is parallel to the axis of symmetry of the pen barrel 1. The drive member 3 is connected to the transmission member 4. The drive member 3 has a first position and a second position relative to the transmission member 4. When the drive member 3 is in the first position, it drives the transmission member 4 to move towards the bottom of the pen barrel 1, and the pen refill 2 extends from the bottom of the pen barrel 1. When the drive member 3 is in the second position, it drives the transmission member 4 to reset, and the pen refill 2 retracts into the pen barrel 1.

[0022] In this technical solution, the pen refill 2 is set in the inner cavity of the pen barrel 1. The top of the pen barrel 1 is rotatably connected to the drive component 3, and the drive component 3 is connected to the pen refill 2 through the transmission component 4. The drive component 3 can rotate freely in any direction on the pen barrel 1, thereby driving the transmission component 4 to move, so that the pen refill moves. The user only needs to rotate the drive component 3 with one hand to extend and retract the pen refill 2, completely avoiding the axial pressing operation required in the traditional design.

[0023] When the drive component 3 rotates to the first position, it drives the transmission component 4 to move towards the bottom of the pen barrel 1, causing the pen tip 2 to extend from the bottom of the pen barrel 1. When the drive component 3 rotates to the second position, it drives the transmission component 4 to reset, causing the pen tip 2 to retract into the inner cavity of the pen barrel 1. By simply rotating the drive component 3 from the first position to the second position, or from the second position to the first position, this simple rotation can precisely control the position of the pen tip 2, completely eliminating the dependence on precise axial pressing, and allowing for easy operation even in bumpy environments or when holding the pen with one hand.

[0024] The drive component 3 acts directly on the transmission component 4, replacing the easily damaged plastic latches and ratchet structure inside the transmission pen. This results in a stronger overall structure and significantly improves the product's impact resistance and durability. It is also ergonomic, allowing for precise control of the pen tip position through simple rotation.

[0025] The driving component 3 includes a first guide structure 31 and a first limiting structure 32, with the first limiting structure 32 located on both sides of the first guide structure 31; the transmission component 4 includes a second limiting structure 41; the first guide structure 31 of the driving component 3 located in the second position is rotatable around the axis of the driving component 3 itself; the first limiting structure 32 of the driving component 3 located in the first position is engaged with the second limiting structure 41.

[0026] In this technical solution, the first guide structure 31 of the driving component 3 can rotate arbitrarily along its own axis. During the rotation, the first limiting structure 32 located on both sides of the first guide structure 31 can be circumferentially locked with the second limiting structure 41, realizing the rotational movement of the driving component 3 between the first position and the second position. The force flow path is short and symmetrical, and the entire mechanism is subjected to balanced force, which can effectively counteract the torque generated by the force on one side, fundamentally eliminating the possibility of backlash and relative sliding in the transmission process.

[0027] In the first position, the first limiting structure 32 and the second limiting structure 41 engage with each other, causing the pen tip 2 to extend from the bottom of the pen barrel 1; in the second position, the first limiting structure 32 and the second limiting structure 41 separate, causing the pen tip 2 to retract from the bottom of the pen barrel 1.

[0028] The specific assembly relationship between the first guide structure 31 and the transmission component 4 is determined by... Figure 2 , Figures 4 to 6As shown, the first guide structure 31 has a receiving cavity 311, and the first guide structure 31 includes a plurality of inclined steps 312 connected in sequence. The inclined steps 312 are disposed on the inner surface of the receiving cavity 311. The second limiting structure 41 is located at the top of the transmission member 4, and at least part of the second limiting structure 41 is accommodated in the receiving cavity 311 at the second position. The second limiting structure 41 is a protrusion, and the protrusion includes a top edge 411. The two side walls of the top edge 411 are arc-shaped transitions, and the plurality of inclined steps 312 can rotate relative to the top edge 411.

[0029] In this embodiment, the first guide structure 31 is preferably a spherical structure or a hemispherical structure. The first guide structure 31 has a receiving cavity 311 inside. Multiple inclined steps 312 connected in sequence are provided on the inner surface of the receiving cavity 311 in order to provide a rotational guide trajectory so that the driving member 3 can achieve flexible rotation at multiple angles.

[0030] In the assembled state, the second limiting structure 41 (protrusion) at the top of the transmission component 4 is housed in the receiving cavity 311. The arc-shaped surface on the top edge of the second limiting structure 41 (protrusion) and the rotational guide trajectory formed by the multiple inclined steps 312 achieve rotational engagement.

[0031] The first guide structure 31 of the drive member 3 in the first position rotates around the protrusion until the first limiting structure 32 can be engaged with the protrusion; and when the second limiting structure 32 separates from the protrusion, the inclined step 312 in the middle of the first guide structure 31 fits against the top edge 411 of the protrusion.

[0032] Specifically, the first limiting structure 32 is a slot, which includes a guide slope 321. The guide slope 321 transitions to the slope step 312 to form a gradually changing guide ramp. The slot of the driving member 3 at the first position engages with the protrusion. The slot of the driving member 3 at the second position separates from the protrusion, and the protrusion can slide along the guide slope 321 and coincide with the axis of the driving member 3.

[0033] When the driving member 3 is in the second position (i.e., the rotation position, where the pen core 2 can retract from the pen barrel 1), the top edge 411 of the protrusion of the second limiting structure 41 separates from the slot, and the protrusion contacts and slides relative to the inclined step 312 of the first guide structure 31 until the top edge 411 of the protrusion can fit against the inclined step 312 of the first guide structure 31 located in the middle.

[0034] When it is necessary to switch from the second position to the first position (i.e., the transmission position, where the pen tip 2 can extend from the pen barrel 1), the drive member 3 moves along its axial direction. During this process, the protrusion on the transmission member 4 first slides along the guide slope 321 of the first limiting structure 32 (slot). The guide slope 321 can smoothly guide the protrusion to the correct engagement position of the slot, which can buffer the impact of collision.

[0035] When the driving component 3 reaches the first position, the protrusion is fully engaged in the first limiting structure 32 (slot), and the structure is stable and reliable.

[0036] In order for the drive component 3 to rotate smoothly between the first and second positions, by Figure 8 As shown, it also includes a cap 5, which is connected to the pen barrel 1. Preferably, the cap 5 is threaded to the top of the pen barrel 1. The cap 5 has a mounting cavity 51 and an opening 52. The mounting cavity 51 communicates with the inner cavity of the pen barrel 1, and the opening 52 communicates with the mounting cavity 51. The opening 52 extends axially along the top of the cap 5. The driving member 3 also includes an operating part 33. The end of the driving member 3 away from the operating part 33 and the transmission member 4 are both located in the mounting cavity 51. The operating part 33 extends out from the opening 52 and is used to operate the driving member 3 to move along the length direction of the opening 52.

[0037] The cap 5 has an axially extending mounting cavity 51 inside, which is connected to the inner cavity of the pen barrel 1 to accommodate related components. The top center of the cap 5 has an opening 52, which is connected to the mounting cavity 51 and extends in a direction parallel to the axial direction of the cap 5. The upper end of the drive member 3 is an operating part 33. Preferably, the operating part 33 has a cylindrical structure for easy operation. The end of the drive member 3 away from the operating part 33 and the transmission member 4 are both housed in the mounting cavity 51 of the cap 5, while the operating part 33 extends outward from the opening 52 at the top of the cap 5. Its cross-sectional shape matches the opening 52 and it can slide in it. When the user applies an axial force to the operating part 33, the entire drive member 3 can be driven to move along the length direction of the opening 52, i.e., the axial direction of the cap 5. Then, the other end of the drive member 3 pushes the transmission member 4 in the mounting cavity 51 to move, transmitting power to the inside of the pen barrel 1.

[0038] The specific assembly relationship between transmission component 4 and cap 5 is determined by... Figure 2 , Figure 4 , Figure 5 and Figure 8 As shown, the end of the mounting cavity 51 away from the opening 52 is a square cavity, and the bottom of the transmission member 4 is a square structure. The bottom of the transmission member 4 is adapted to be slidably disposed in the square cavity, which restricts the transmission member 4 to slide only along the length direction of the mounting cavity 51, and the structure is stable.

[0039] It should be noted that, by Figure 2 and Figure 4 As shown, it also includes a return spring 6. The inner cavity of the pen barrel 1 has an annular stepped surface 11. The pen core 2 is axially movable and passes through the pen barrel 1. The return spring 6 is sleeved on the tail end of the pen core 2. The stepped surface 11 is located at the bottom of the pen barrel 1. The return spring 6 is located between the pen core 2 and the stepped surface 11. The pen core 2 has an annular limiting surface, and the end of the annular limiting surface facing the pen barrel is the tail end. This is an existing technical design and will not be described in detail here. The return spring 6 is located between the annular limiting surface and the stepped surface 11. When the driving member 3 rotates from the second position to the first position, the transmission member 4 drives the pen core 2 to move downward. The annular limiting surface compresses the return spring 6 until it abuts against the stepped surface 11, driving the pen core 2 to extend out of the pen barrel 1. When the driving member 3 rotates from the first position to the second position, the transmission member 4 moves upward, the pen core return spring 6 separates from the stepped surface 11, and the pen core 2 retracts into the pen barrel 1. The operation is simple and reliable.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
