Description

Technical Field

[0001] This invention relates to the technical field of stationery, specifically to a doll pen with a range-extending structure. Background Technology

[0002] Currently, a type of pen with movable toys is very popular among children and young people. Its typical feature is that various styles of dolls are set at the back of the pen, and the dolls are controlled to move by the operation buttons on the side of the pen barrel, thereby increasing the fun of using the pen.

[0003] For example, a press-type pen disclosed in Chinese utility model (CN202321494983.X). The device includes a pen barrel, a slider, and a refill. The pen barrel is made of opaque material. The slider is inserted into and slides along the axial direction of the pen barrel at its top. The refill slides along the axial direction of the pen barrel within its cavity. The slider is driven by a telescopic locking mechanism to extend and retract the refill relative to the pen barrel. A decorative element is detachably mounted on the top of the slider, and a transparent cover for accommodating the decorative element is detachably mounted on the top of the pen barrel. By pushing the slider downwards, the telescopic locking mechanism is activated, allowing the refill to extend and retract relative to the pen barrel. When the refill extends out of the pen barrel, the slider and decorative element move downwards as a whole, concealing the decorative element within the opaque pen barrel. When the refill retracts into the pen barrel, the refill and decorative element move upwards as a whole, concealing the decorative element within the transparent cover, making it visible to the user.

[0004] In the structure shown in the aforementioned patent, the decorative element is fixedly mounted on the sliding element, which in turn retracts and extends in conjunction with the pen refill via a telescopic locking mechanism. The decorative element and the pen refill move synchronously and have the same stroke. However, due to the limitation of the pen refill's stroke, the decorative element can only move within a small range. This results in certain limitations on the height of the decorative element if it is to be completely hidden inside the pen barrel. On the other hand, if the stroke of the pen refill is increased accordingly, it will cause other problems such as the pen refill extending too far, affecting writing; the pen refill swinging within the pen barrel and spring due to the excessive distance between it and the pen tip when retracted; and the increased stroke of the operating components affecting the feel of operation. Summary of the Invention

[0005] The present invention provides a toy pen with an extended range structure, wherein the toy has a longer range of motion when it extends and retracts relative to the pen barrel.

[0006] The present invention relates to a toy pen with an extended range structure, comprising a pen barrel, a pen core, a telescopic locking mechanism for driving the pen core to extend and retract, and a first spring. An operating component capable of moving along the front-rear direction of the pen barrel is located on the rear side of the pen barrel. One end of the operating component passes through the pen barrel and is driven to engage with the telescopic locking mechanism. A vertical groove is provided on the rear side of the pen barrel to engage with the operating component. An opening is provided at the rear of the pen barrel, through which a toy is telescopically mounted. The toy can be a small human or animal-shaped toy, or a decorative item. A rotating ring is provided inside the pen barrel. This rotating ring is linked to the operating component / telescopic locking mechanism and is driven to move along the front-rear direction of the pen barrel while simultaneously driving the pen core to extend and retract. A first transmission mechanism is provided on the outer side of the rotating ring and the inner side of the pen barrel. This first transmission mechanism enables the rotating ring to move relative to the front-rear direction of the pen barrel. The rotating ring has a transmission rod connected to its center. The rear end of the transmission rod is connected to a doll. A second transmission mechanism is located on the inner side of the rotating ring and the outer side of the transmission rod. This second transmission mechanism drives the transmission rod to move back and forth relative to the rotating ring when the rotating ring rotates. Thus, while the operating component controls the extension and retraction of the pen refill, it also drives the rotating ring to move back and forth along the pen barrel. Simultaneously, it drives the transmission rod connected to the rotating ring to move back and forth. The rotating ring also rotates as it moves back and forth along the pen barrel, and this rotation further drives the transmission rod to move back and forth relative to the rotating ring. This results in a longer stroke for the transmission rod than for the rotating ring, giving the doll connected to the rear end of the transmission rod a longer stroke relative to the pen refill's extension and retraction. This increases the doll's stroke, allowing it to be fully retracted into or fully extended from the pen barrel during pen refill extension and retraction. This structural design does not require changing the stroke of the pen refill in existing push-to-extract pens, ensuring both writing and refill efficiency. It also allows for a larger doll and improves the doll's retractable and retractable storage capabilities.

[0007] Furthermore, the telescopic locking mechanism includes a pressure rod at its rear end, with an extension integrally formed at the rear end. One end of the operating component, which passes through the pen barrel, is connected to the extension. The rotating ring is rotatably connected to the rear end of the extension. When the operating component is pressed, it can drive the pressure rod forward, cooperating with other components of the telescopic locking mechanism, such as locking components and guide rails, to push the pen tip forward along the pen barrel and lock it in the extended state. When the operating component is pressed again, the pen tip can be unlocked, and the first spring drives the pen tip and the pressure rod to move backward to reset. The pressure rod can also drive the rotating ring to move back and forth through the extension.

[0008] Furthermore, the extension is a cylindrical structure, and the end of the operating component that passes through the pen barrel includes an annular connecting part. The annular connecting part of the operating component is sleeved on the outside of the extension. The rotating ring is rotatably sleeved on the rear end of the extension. The front end of the transmission rod is movably inserted through the inner hole of the extension. The transmission rod is not easy to shake, which improves the connection effect of the operating component, the rotating ring and the transmission rod, making the structure more compact and reliable.

[0009] Furthermore, the front end of the transmission rod is provided with a limiting part, and the pressure rod includes an inner cavity that is connected to the inner hole of the extension. The limiting part is movably disposed in the inner cavity of the pressure rod, and a first annular stepped surface is provided in the inner cavity of the pressure rod. The first annular stepped surface can cooperate with the limiting part to prevent the pressure rod from coming out backward.

[0010] Furthermore, a second spring is sleeved on the transmission rod, and the second spring forms an abutting engagement with the rotating ring and the doll respectively. An anti-rotation limiting engagement is formed between the transmission rod and the pressure rod, or between the transmission rod and the pen barrel, so that the rotating ring will not drive the transmission rod to rotate together when it rotates, ensuring the transmission effect between the rotating ring and the transmission rod. The first transmission mechanism includes a first guide slope disposed on the outer side of the rotating ring and a first guide rib disposed on the inner side of the pen barrel and forming a sliding contact engagement with the first guide slope. The second transmission mechanism includes a second guide slope disposed on the inner side of the rotating ring and a second guide rib disposed on the outer side of the transmission rod and forming a sliding contact engagement with the second guide slope. The elastic force applied by the second spring to the rotating ring ensures reliable contact engagement between the first guide slope and the first guide rib, as well as between the second guide slope and the second guide rib, improving the transmission effect.

[0011] Furthermore, the doll is fixedly connected to the rear end of the transmission rod. The transmission rod, through the doll and pen barrel connected to its rear end, forms an anti-rotation limiting fit, which can prevent the transmission rod and pen barrel from rotating relative to each other, and ensure reliable transmission between the transmission rod and the rotating ring.

[0012] Furthermore, a second annular stepped surface is formed between the pressure rod and the extension. The front side of the annular connecting part forms a limiting fit with the second annular stepped surface to prevent the annular connecting part from moving forward relative to the pressure rod. The rear side of the annular connecting part forms a limiting fit with the rotating ring. Alternatively, a limiting rib is provided at the sleeve fit between the annular connecting part and the extension to prevent the annular connecting part from moving backward relative to the pressure rod, so that the annular connecting part can be sleeved and positioned on the pressure rod without generating relative displacement in the forward direction.

[0013] Furthermore, the inner hole of the rotating ring includes a front part and a rear part. The front part of the inner hole of the rotating ring has a larger diameter than the rear part. A third annular stepped surface is formed between the front part and the rear part of the inner hole of the rotating ring. The front part of the inner hole is sleeved with the rear end of the extension. The third annular stepped surface and the rear end of the extension form a limiting fit to prevent the rotating ring from moving forward relative to the pressure rod. At the same time, it can also limit the insertion depth of the extension relative to the rotating ring. A limiting rib is provided at the sleeve fit between the front part of the inner hole of the rotating ring and the extension to prevent the rotating ring from coming off the rear end of the extension. This allows the rotating ring to be sleeved and positioned on the extension without relative displacement in the forward direction, and allows the rotating ring to form a rotational fit with the extension.

[0014] Furthermore, the outer side of the annular connecting part and the inner side of the pen barrel are provided with an anti-rotation structure to prevent the annular connecting part from rotating relative to the pen barrel, which can improve the connection effect of the operating components and reduce shaking.

[0015] The beneficial effects of the present invention are as follows: The doll pen with the extended range structure of the present invention adopts a press-type core ejection structure. The doll at the rear end of the pen barrel can retract forward into the pen barrel or extend backward from the pen barrel as the core extends and retracts. Moreover, the doll has a longer range of motion relative to the extension and retraction of the core. While ensuring that the core has a reasonable extension and retraction range, the extension and retraction effect of the doll is improved, and the requirements for the height of the doll are reduced.

Detailed Implementation

[0017] An embodiment of the toy pen with a range-extending structure of the present invention, such as... Figure 1-11 As shown, the device includes a pen barrel 1 (also called a pen case). Inside the pen barrel 1 is a pen refill 2, a telescopic locking mechanism for driving the pen refill 2 to extend and retract, and a first spring 3. The first spring 3 is located between the front end of the pen refill 2 and the front end of the pen barrel 1, and is used to drive the pen refill 2 to move in the retracting direction. The telescopic locking mechanism abuts against the rear end of the pen refill 2, and is used to drive the pen refill 2 to move in the extending direction. An operating component 5, capable of moving along the front-back direction of the pen barrel 1, is located on the rear side of the pen barrel 1. The operating component 5 is operated in conjunction with the hand. One end of the operating component 5 passes through the pen barrel 1 and is driven by the telescopic locking mechanism. The rear end of the pen barrel 1 has an opening 10, at which a doll 6 is telescopically mounted. A rotating ring 7 is located inside the pen barrel 1. This rotating ring 7 is linked with the operating component 5 / telescopic locking mechanism and can be driven to move along the front-back direction of the pen barrel 1 while simultaneously driving the pen refill 2 to extend and retract. A first transmission mechanism is located on the outer side of the rotating ring 7 and the inner side of the pen barrel 1. Through the first transmission mechanism, the rotating ring 7... When the pen refill 1 moves back and forth, it causes the rotating ring 7 to rotate. A transmission rod 8 is connected to the center of the rotating ring 7. The rear end of the transmission rod 8 is connected to the doll 6. A second transmission mechanism is provided on the inner side of the rotating ring 7 and the outer side of the transmission rod 8. The second transmission mechanism can drive the transmission rod 8 to move back and forth relative to the rotating ring 7 when the rotating ring 7 rotates. Thus, while the operating component 5 controls the extension and retraction of the pen refill 2, it also drives the rotating ring 7 to move back and forth along the pen refill 1. At the same time, it can also drive the transmission rod 8 connected to the rotating ring 7 to move back and forth. The rotating ring 7 will also rotate when it moves back and forth along the pen refill 1. When the rotating ring 7 rotates, it will also drive the transmission rod 8 to move back and forth relative to the rotating ring 7. This makes the back and forth travel of the transmission rod 8 greater than that of the rotating ring 7. This gives the doll 6, which is connected to the rear end of the transmission rod 8, a longer travel distance relative to the extension and retraction travel of the pen refill 2. This allows the doll 6 to be completely retracted into the pen refill 1 or completely extended out of the pen refill 1 during the extension and retraction of the pen refill 2. This structural design does not require changing the movement stroke of the existing press-to-extract pen refill 2, ensuring the writing and storage effect of the refill, allowing the height of the doll 6 to be made larger, and improving the telescopic storage effect of the doll 6.

[0018] The structure and working principle of the telescopic locking mechanism are common in push-to-open pens and are mature existing technologies. Its specific structure and principle are as follows: The telescopic locking mechanism includes a pressure rod 41, a guide rail 42, and a locking member 43. The pressure rod 41 is driven forward by the operating component 5. The front end of the locking member 43 supports and cooperates with the pen refill 2. The guide rail 42 consists of multiple vertical ribs spaced circumferentially on the inner side of the pen barrel 1. The guide rail 42 is integrally formed on the pen barrel 1. The pressure rod 41 and guide rail 42, as well as the locking member 43 and guide rail 42, all form an anti-rotation cooperation, allowing the pressure rod 41 and locking member 43 to move only in the front-back direction of the pen barrel 1. When the pressure rod 41 moves forward, it pushes the locking member 43 forward, thereby pushing... When the pen tip 2 extends, the anti-rotation engagement between the locking member 43 and the guide rail 42 is released. The helical teeth at the contact point between the locking member 43 and the pressure rod 41 drive the locking member 43 to rotate. After the helical teeth of the locking member 43 rotate, the first spring 3 drives it to abut against the front end of the guide rail 42, thereby keeping the locking member 43 in the state where the pen tip 2 extends forward. When the pressure rod 41 moves forward again, it can push the locking member 43 forward, causing the locking member 43 to rotate again. When the first spring 3 drives the locking member 43 to move backward, the front end positions of the locking member 43 and the guide rail 42 change, and the abutment and limiting effect is no longer produced, allowing the locking member 43 to move backward a greater distance, so that the pen tip 2 can be retracted into the pen barrel 1.

[0019] The rear end of the pressure rod 41 is integrally formed with an extension 411. One end of the operating component 5, which is inserted into the pen barrel 1, is connected to the extension 411. The rotating ring 7 is rotatably connected to the rear end of the extension 411. When the operating component 5 is pressed, it can drive the pressure rod 41 to move forward. It can cooperate with other components of the telescopic locking mechanism to push the pen core 2 forward and lock it in the extended state. When the operating component 5 is pressed again, the pen core 2 can be unlocked. The first spring 3 drives the pen core 2 and the pressure rod 41 to move backward and reset. The pressure rod 41 can also drive the rotating ring 7 to move back and forth synchronously through the extension 411.

[0020] The extension 411 has a cylindrical structure. One end of the operating component 5, which passes through the pen barrel 1, includes an annular connecting part 51. The other end of the operating component 5, located outside the pen barrel 1, is the operating part. In this embodiment, the operating part is a spherical structure, which, in addition to being operable by hand, also prevents the pen from rolling on the table when it is placed on the table. In other embodiments, a pen clip structure can also be used. The annular connecting part 51 of the operating component 5 is sleeved on the outside of the extension 411. The rotating ring 7 is rotatably sleeved on the rear end of the extension 411. The front end of the transmission rod 8 is movably inserted through the inner hole of the extension 411. The transmission rod 8 is not easy to shake, which improves the connection effect of the operating component 5, the rotating ring 7, and the transmission rod 8, making the structure more compact and reliable.

[0021] The outer side of the annular connecting part 51 and the inner side of the pen barrel 1 are provided with an anti-rotation structure to prevent the annular connecting part 51 from rotating relative to the pen barrel 1, which can improve the connection effect of the operating component 5 and reduce shaking. Specifically, in this embodiment, the anti-rotation cooperation is achieved by the guide rib provided on the inner side of the pen barrel 1 and the guide groove on the outer side of the annular connecting part 51.

[0022] The transmission rod 8 has a limiting part 81 at its front end. The pressure rod 41 includes an inner cavity 410, which is connected to the inner hole of the extension part 411. The limiting part 81 is movably disposed in the inner cavity 410 of the pressure rod 41. The inner cavity 410 of the pressure rod 41 has a first annular stepped surface 41a. The first annular stepped surface 41a can cooperate with the limiting part 81 to prevent the pressure rod 41 from coming out of the inner cavity 410. During assembly, the transmission rod 8 can be inserted and installed by inserting it into the front opening of the pressure rod 41.

[0023] A second spring 9 is sleeved on the transmission rod 8. The second spring 9 forms an abutment fit with the rotating ring 7 and the doll 6 respectively. An anti-rotation limiting fit is formed between the transmission rod 8 and the pressure rod 41, or between the transmission rod 8 and the pen barrel 1, so that the rotating ring 7 will not drive the transmission rod 8 to rotate together when rotating, ensuring the transmission effect between the rotating ring 7 and the transmission rod 8. The first transmission mechanism includes a first guide slope 71 disposed on the outer side of the rotating ring 7 and a first guide rib 11 disposed on the inner side of the pen barrel 1 and forming a sliding contact fit with the first guide slope 71. The second transmission mechanism includes a second guide slope 72 disposed on the inner side of the rotating ring 7 and a second guide rib 82 disposed on the outer side of the transmission rod 8 and forming a sliding contact fit with the second guide slope 72. The elastic force applied by the spring 9 to the rotating ring 7 ensures reliable contact between the first guide slope 71 and the first guide rib 11, as well as the second guide slope 72 and the second guide rib 82. When the rotating ring 7 moves along the pen barrel 1 in the front-back direction, it can also drive the transmission rod 8 to move back and forth relative to the pen barrel 1. The sliding contact between the first guide slope 71 and the first guide rib 11 can also cause the rotating ring 7 to rotate. When the rotating ring 7 rotates, the cooperation between the second guide slope 72 and the second guide rib 82 causes the transmission rod 8 to move back and forth relative to the rotating ring 7, thereby making the back-and-forth movement stroke of the transmission rod 8 greater than the back-and-forth movement stroke of the rotating ring 7. The guide rib is provided with a slope to improve the sliding contact effect with the guide slope.

[0024] The doll 6 is inserted and fixed to the rear end of the transmission rod 8. The doll 6 and the transmission rod 8 cannot move relative to each other. The transmission rod 8 forms an anti-rotation limiting fit with the doll 6 and the pen barrel 1 connected to its rear end. Specifically, in this embodiment, the anti-rotation fit is achieved by the guide rib set on the inner side of the pen barrel 1 and the guide groove on the front side of the doll 6.

[0025] A second annular step surface 41b is formed between the pressure rod 41 and the extension 411. The front side of the annular connecting part 51 forms a limiting fit with the second annular step surface 41b to prevent the annular connecting part 51 from moving forward relative to the pressure rod 41. The rear side of the annular connecting part 51 forms a limiting fit with the rotating ring 7. Alternatively, a limiting rib (ring-shaped) is provided at the sleeve fit between the annular connecting part 51 and the extension 411 to prevent the annular connecting part 51 from moving backward relative to the pressure rod 41, so that the annular connecting part 51 can be sleeved and positioned on the pressure rod 41 without producing relative displacement in the forward direction.

[0026] The inner hole of the rotating ring 7 includes a front part and a rear part. The front part of the inner hole of the rotating ring 7 has a larger diameter than the rear part. A third annular step surface 7a is formed between the front part and the rear part of the inner hole of the rotating ring 7. The front part of the inner hole is sleeved with the rear end of the extension 411. The third annular step surface 7a and the rear end of the extension 411 form a limiting fit. A limiting rib (ring-shaped) is provided at the sleeve fit between the front part of the inner hole of the rotating ring 7 and the extension 411 to prevent the rotating ring 7 from coming off the rear end of the extension 411. This allows the rotating ring 7 to be sleeved and positioned on the extension 411 without relative displacement in the forward direction, and allows the rotating ring 7 to form a rotational fit with the extension 411.

[0027] In addition to the above-mentioned structure, a vertical groove 12 is provided on the rear side of the pen barrel 1. The front and rear ends of the vertical groove 12 correspond to the front and rear directions of the pen barrel 1. The operating component 5 can move along the front and rear directions of the vertical groove 12. Furthermore, the vertical groove 12 allows the annular connecting part 51 to be vertically inserted into the inner hole of the pen barrel 1 from the outside. After rotating in the inner hole of the pen barrel 1, the annular connecting part 51 cooperates with the extension part 411 for installation.

[0028] The above embodiments are merely one preferred embodiment of the present invention. Ordinary variations and substitutions made by those skilled in the art within the scope of the technical solution of the present invention are all included within the protection scope of the present invention.
