Description
Technical Field
[0001] This utility model relates to a toy pen with a retractable and extendable lead. Background Technology
[0002] Many pens on the market now have movable parts that resemble toys. In some toy pens with retractable refills, the retraction of the refill can even be linked to the movement of the toy's movable parts. By controlling the retraction of the refill, the movable parts of the toy can be moved in tandem, making it highly playable and fun.
[0003] For the aforementioned pens, the pen barrel typically features an independent operating component for driving the extension and retraction of the pen refill. This component and the toy are linked via a transmission mechanism. These pens are usually click-type, and both the pen refill driving structure and the toy's transmission mechanism are generally quite complex, requiring high precision in manufacturing and assembly. Considering the pen's grip and aesthetics, the toy is usually located at the rear of the pen barrel, while the operating component is positioned on the side, resulting in a less streamlined and aesthetically pleasing overall shape and a less cohesive design. Furthermore, existing pens of this type typically require the hand to operate the toy's movable parts to generate movement; currently, there is no method to use the hand to operate the toy's movable parts to control the pen refill extension and retraction. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, this utility model provides a toy pen in which the extension and retraction of the pen tip can be linked by the movement of the movable part of the movable toy operated by hand.
[0005] This utility model relates to a toy pen with a telescopic retractable pen core, comprising a pen barrel, a pen core, and a movable toy. The pen core is movably disposed within the pen barrel, and the movable toy is disposed at the rear end of the pen barrel. The movable toy has a movable part, and the movable part of the movable toy and the pen core are connected and engaged by a transmission mechanism disposed within the pen barrel. The movable toy includes a housing disposed at the rear end of the pen barrel and a rotating body disposed rotatably within the housing cavity. The rotating body is the movable part of the toy. The front side of the housing includes a window for the user to contact the rotating body. The user contacts the rotating body through the window and uses the friction of the contact to operate the rotating body to rotate. The transmission mechanism includes a spring, a pen core support seat, and a rotating component. The pen core support seat abuts against the rear end of the pen core, providing support for the pen core when the pen is writing. The spring serves to abut between the front end of the pen refill and the pen barrel, driving the pen refill to return to its original position. It also drives the rear end of the pen refill to remain abutted against the front end of the pen refill support. The pen refill support and the pen barrel form a guiding fit that allows the pen refill support to move back and forth relative to the pen barrel but prevents it from rotating relative to the pen barrel. Specifically, the rotation of the pen refill support can be prevented by a guide groove on the side of the pen refill support and a guide rib on the inner wall of the pen barrel. The rotating component is rotatably disposed inside the pen barrel, connected to the rotating body and able to rotate synchronously. A guide slope is provided along the circumference of the rotating component, and a corresponding protrusion is provided on the pen refill support to guide the movement in accordance with the guide slope. A notch is provided at the front end of the guide slope of the rotating component for the protrusion to be inserted and positioned.
[0006] When the rotating body rotates, it drives the rotating component to rotate. When the protrusion is at the rear end of the guide slope, the pen lead is in the rear position, which corresponds to the retracted state. When the rotating component is driven to rotate, the protrusion can move forward along the guide slope, causing the pen lead support to move forward relative to the rotating component, and the pen lead to gradually extend forward. When the protrusion moves to the notch, it can form a positioning fit with it, and at the same time keep the pen lead in the extended state, so that it will not automatically retract when writing. When it is necessary to drive the pen lead to retract, a certain force is applied to the rotating body, causing the protrusion to disengage from the notch and fall back onto the guide slope. The elastic force of the spring can drive the rotating component to rotate on its own, so that the protrusion moves to the rear end of the guide slope. At this time, the rotating body will also rotate on its own.
[0007] Compared to traditional push-button toy pens, the pen refill drive structure of this application is simpler. The pen refill support and rotating component do not require complex gear structures, resulting in lower precision requirements for the fit between parts, higher durability, and greater reliability. Furthermore, the direct connection between the rotating component and the movable part of the toy allows for more direct force transmission, making it less susceptible to structural strength issues. More importantly, compared to existing toy pen operation methods, this invention allows direct operation of the movable part of the toy to drive the pen refill's extension and retraction, a novel approach.
[0008] Furthermore, the rotating body has at least two patterns distributed along its circumference. These two patterns, respectively, are displayed in conjunction with the window when the pen is in the lead-out and lead-retracting states, increasing the fun of the movable toy. Alternatively, more patterns can be configured; for example, corresponding patterns can be arranged in the intermediate state between the lead-out and lead-retracting states. These patterns will pass through the window during the rotation of the rotating body, creating a marquee effect. Furthermore, when the mating point between the rotating component and the pen lead support has more than one number of notches and guide ramps arranged circumferentially, a corresponding pattern is displayed at the window when the protrusion is at the rear end of each guide ramp and at the front notch.
[0009] Furthermore, the box is shaped like the head or full body of a doll (including the head), the window is located on the face of the doll's head, and the pattern is the doll's facial expression, which adds to the fun.
[0010] It should be noted that, in order to increase the friction when the rotating part comes into contact with the hand, the rotating body may have a rough surface, or a rubber layer may be covered on the surface of the rotating body or anti-slip textures may be set on the surface to increase the friction.
[0011] Furthermore, the front end of the housing includes a cylindrical insertion part, which is inserted into the pen barrel through the opening at the rear end of the pen barrel to connect the housing and the pen barrel. The rotating part is rotatably disposed in the inner hole of the cylindrical insertion part. Through the cooperation of the cylindrical insertion part and the pen refill support, the cylindrical insertion part and the pen barrel form a limiting fit that prevents relative rotation.
[0012] Furthermore, the rear end of the pen refill support includes a connecting post, the front end of the rotating component is provided with a connecting hole that mates with the connecting post, the protrusion is provided on the side of the connecting post, the inner side of the connecting hole of the rotating component has an annular convex step, the guide slope and the notch are both provided on the convex step, which facilitates the connection and mating of the pen refill support and the rotating component. In order to facilitate the protrusion to come out of the notch, the notch and the protrusion preferably have arc-shaped or inclined contact mating surfaces.
[0013] Furthermore, the front end of the rotating body includes a plug hole, and the rear end of the rotating component includes a plug post that engages with the plug hole for positioning. The plug post and the rotating body form a limiting fit that prevents relative rotation. The connection structure is simple, enabling the rotating body to drive the rotating component to rotate synchronously when it rotates.
[0014] Furthermore, the rotating body is a spherical structure, including relatively flat spherical structures at the front and rear ends. The rotating body includes a front cover, a rear cover, and a cavity formed by splicing the front and rear covers. This design can save materials, reduce the weight of the rotating body, and prevent the center of gravity of the pen from being too far back. A central column is integrally connected to the rear cover. The central column is located in the cavity. The insertion hole is set at the front end of the central column. The front cover has an opening at the corresponding front end of the central column to facilitate the insertion of the insertion column and the insertion hole.
[0015] Furthermore, a connecting shaft is provided at the rear end of the rear cover, which forms a rotatable plug-in fit with the top of the inner cavity of the box, thereby improving the rotatable connection effect between the rotating parts and the box.
[0016] The advantages of this utility model are: simple structure, convenient assembly, low requirements for precision matching between parts, more direct force transmission, better service life and reliability. In addition, the pen refill can be operated by the movable part of the movable toy, which is a novel way of use. Attached Figure Description

[0024] The structure of the toy pen with linked retractable pen tip in this embodiment of the utility model is as follows: Figure 1-7As shown, the device includes a pen barrel 1, a pen refill 2, and a movable toy 3. The pen refill 2 is movably disposed within the pen barrel 1, and the movable toy 3 is disposed at the rear end of the pen barrel 1. The movable toy 3 has a movable part (i.e., a rotating body 3232). The movable part of the movable toy 3 and the pen refill 2 are connected and engaged by a transmission mechanism disposed within the pen barrel 1. The movable toy 3 includes a housing 31 disposed at the rear end of the pen barrel 1 and a rotating body 32 rotatably disposed within the cavity of the housing 31. The rotating body 32 is the movable part of the movable toy 3. The front side of the housing 31 includes a window 311 for the user to contact the rotating body 32. The user contacts the rotating body 32 through the window 311 and uses the friction of the contact to rotate the rotating body 32. The transmission mechanism includes a spring 4, a pen refill support 5, and a rotating component 6. The pen refill support 5 abuts against the rear end of the pen refill 2, providing support for the pen refill 2 when the pen is writing. Spring 4 is abutted between the front end of pen refill 2 and pen barrel 1 and is used to drive pen refill 2 to move backward. It is also used to drive the rear end of pen refill 2 to keep it abutting against the front end of pen refill support 5. The pen refill support 5 and pen barrel 1 form a guide fit that only allows pen refill support 5 to move back and forth relative to pen barrel 1 and prohibits it from rotating relative to pen barrel 1. Specifically, the rotation of pen refill support 5 can be prohibited by the cooperation of guide groove 50 provided on the side of pen refill support 5 and guide rib provided on the inner side wall of pen barrel 1. The rotating part 6 is rotatably provided in pen barrel 1. The rotating part 6 is connected to the rotating body 32 and can rotate synchronously. A guide slope 611 is provided on the rotating part 6 along the circumferential direction. A protrusion 511 is provided on the pen refill support 5 to cooperate with the guide slope 611 to guide the movement. The rotating part 6 is provided with a notch 612 at the front end of the guide slope 611 for the protrusion 511 to be inserted and positioned.
[0025] When the rotating body 32 rotates, it can drive the rotating component 6 to rotate. When the protrusion 511 is located at the rear end of the guide slope 611, the pen lead 2 is in a rear position, which corresponds to the retracted state. When the rotating component 6 is driven to rotate, the protrusion 511 can move forward along the guide slope 611, causing the pen lead support 5 to move forward relative to the rotating component 6, and the pen lead 2 to gradually extend forward. When the protrusion 511 moves to the notch 612, it can form a positioning fit with it, and at the same time keep the pen lead 2 in the extended state, so that it will not automatically retract when writing. When it is necessary to drive the pen lead 2 to retract, a certain force is applied to the rotating body 32, so that the protrusion 511 is dislodged from the notch 612 and falls back onto the guide slope 611. The elastic force of the spring 4 can drive the rotating component 6 to rotate by itself, so that the protrusion 511 moves to the rear end of the guide slope 611 by itself. At this time, the rotating body 32 will also rotate by itself.
[0026] Compared to traditional push-button toy pens, the pen refill 2 driving structure of this application is simpler. The pen refill support 5 and the rotating component 6 do not require complex gear structures, resulting in lower precision requirements for the fit between components, higher durability, and greater reliability. Furthermore, the direct drive between the rotating component 6 and the movable part of the movable toy 3 ensures more direct force transmission and is less susceptible to structural strength issues. More importantly, compared to existing toy pen operation methods, this invention allows direct operation of the movable part of the movable toy 3 to drive the pen refill 2's extension and retraction, a novel operating method.
[0027] The rotating body 32 has at least two patterns (not shown in the figure) distributed circumferentially. The two patterns are displayed in conjunction with the window 311 when the pen is in the lead-out and lead-retracting states, increasing the fun of the movable toy 3. In addition, more patterns can be configured. For example, corresponding patterns can be configured in the intermediate state when switching between the lead-out and lead-retracting states. These patterns will pass through the window 311 during the rotation of the rotating body 32, creating a marquee effect. Alternatively, when the mating part of the rotating component 6 and the pen lead support 5 has more than one number of notches 612 and guide slopes 611 arranged circumferentially, a corresponding pattern is displayed at the window 311 when the protrusion 511 is at the rear end of each guide slope 611 and the front notch 612.
[0028] In this embodiment, there are four patterns. The corresponding rotating component 6 has four guide ramps 611 and two notches 612 arranged circumferentially. Each notch 612 has two opposing guide ramps 611 connected to its two circumferential sides. The rear ends of two adjacent circumferentially inclined guide ramps 611 are connected, meaning there are two "rear ends" and two "front ends" corresponding to the four patterns circumferentially. When the protrusion 511 is at the front end, it corresponds to the core-out state; when it is at the rear end, it corresponds to the core-retracting state. The two patterns displayed in the window can have the same pattern content when corresponding to the core-out or core-retracting state. Furthermore, this allows the rotating body to switch between core-out and core-retracting by rotating in a single direction, eliminating the need for reverse rotation and making operation more convenient.
[0029] like Figure 1 , 2 As shown in Figure 6, the box 31 is the head of the doll. In other embodiments, it can also be a full-body model (including the head). The window 311 is set at the face position of the doll's head, and the pattern is the doll's facial expression, which has better fun.
[0030] It should be noted that, in order to increase the friction when the rotating part 6 comes into contact with the hand, the rotating body 32 may have a rough surface, or a rubber layer may be covered on the surface of the rotating body 32 or anti-slip textures may be set on the surface to increase the friction.
[0031] The front end of the housing 31 includes a cylindrical insertion part 312. The cylindrical insertion part 312 is inserted into the pen barrel 1 through the opening at the rear end of the pen barrel 1, thereby connecting the housing 31 and the pen barrel 1. The rotating part 6 is rotatably disposed in the inner hole of the cylindrical insertion part 312. Through the cooperation of the cylindrical insertion part 312 and the pen refill support 5, the cylindrical insertion part 312 and the pen barrel 1 form a limiting fit that prevents relative rotation. Specifically, relative rotation can be prevented by the cooperation of the limiting rib on the cylindrical insertion part 312 and the limiting groove on the inner side wall of the pen barrel 1.
[0032] The rear end of the pen refill support 5 includes a connecting post 51, and the front end of the rotating component 6 is provided with a connecting hole 61 that mates with the connecting post 51. The protrusion 511 is provided on the side of the connecting post 51, and the inner side of the connecting hole 61 of the rotating component 6 has an annular raised step. The guide slope 611 and the notch 612 are both provided on the raised step (e.g., Figure 5 As shown), to facilitate the connection and engagement of the pen refill support 5 and the rotating component 6, and to facilitate the disengagement of the protrusion 511 from the recess 612, the recess 612 and the protrusion 511 preferably have arc-shaped or inclined contact surfaces. For example, in this embodiment, as shown... Figure 5 As shown, the notch 612 has an arcuate profile (including the connection with the guide ramp 611), such as Figure 4 As shown, the protrusion 511 is wedge-shaped.
[0033] The front end of the rotating body 32 includes a plug hole 321, and the rear end of the rotating component 6 includes a plug post 62 that is inserted and positioned in conjunction with the plug hole 321. The plug post 62 and the rotating body 32 form a limiting fit that prevents relative rotation. Relative rotation can also be prevented by the limiting rib on the plug post 62 and the limiting groove on the inner sidewall of the plug hole 321. The connection structure is simple, so that the rotating body 32 can drive the rotating component 6 to rotate synchronously when it rotates.
[0034] The rotating body 32 has a spherical structure, including relatively flat spherical structures at the front and rear ends. The rotating body 32 includes a front cover 322, a rear cover 323, and a cavity 320 formed by splicing the front cover 322 and the rear cover 323. This design facilitates processing, saves materials, reduces the weight of the rotating body 32, avoids the center of gravity of the pen being too far back, and improves the grip when writing. A central column 3231 is integrally connected to the rear cover 323. The central column 3231 is located in the cavity 320. The insertion hole 321 is located at the front end of the central column 3231. The front cover 322 has an opening 3221 at the front end of the corresponding central column 3231 to facilitate the insertion of the insertion post 62 and the insertion hole 321.
[0035] The rear end of the rear cover 323 is provided with a connecting shaft 3232, which forms a rotatable insertion fit with the top of the inner cavity of the housing 31, thereby improving the rotatable connection effect between the rotating part 6 and the housing 31.
[0036] The above embodiments are merely one preferred embodiment of the present utility model. Ordinary changes and substitutions made by those skilled in the art within the scope of the present utility model's technical solution are all included within the protection scope of the present utility model.
