Abstract
Description
Technical Field
[0001] This utility model relates to a toy pen with movable wings. 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 be linked to the movement of the movable parts of the toy. By controlling the retraction of the refill, the movable parts of the toy can be moved in tandem, resulting in a highly playable and fun experience.
[0003] To achieve linkage between the pen retraction and the movable toy, a transmission mechanism is usually required between the control part (usually a push button or push button) used to control the retraction and extension of the pen retraction and the movable part of the movable toy. For some toys with wing shapes, such as birds, insects, and pterosaurs, it is necessary for their two wings to flap synchronously. This places certain requirements on the construction of the transmission mechanism, which usually requires a linkage to achieve transmission. Such transmission mechanisms usually take up a lot of space. In order to make it possible to be built into the pen barrel, the diameter of the pen barrel must be made larger. If only the rear end of the pen barrel is thickened, the pen will appear top-heavy and the appearance will not be very aesthetically pleasing. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, this utility model provides a toy pen with a movable wing structure. When the operating component controls the extension and retraction of the pen core, it can link the two wings of the movable toy to flap synchronously. Moreover, the structure is simple and compact, and the appearance is more beautiful.
[0005] This utility model relates to a toy pen with movable wings, comprising a pen barrel, a telescopic locking mechanism, a push button, a pen core, a spring, and a movable toy located at the rear end of the pen barrel. The spring rests between the front end of the pen core and the pen barrel. The push button is movably connected to the pen barrel along its front-to-back direction. The push button includes a connecting end located in the inner cavity of the pen barrel and an operating end located on the outside of the pen barrel. The connecting end of the push button is connected to the telescopic locking mechanism, which is connected to the rear end of the pen core. The push button, through the telescopic locking mechanism, links the extension and retraction of the pen core. The movable toy includes two movable wings, which are rotatably located at the rear end of the pen barrel. The rear end of the inner cavity of the pen barrel includes a transmission chamber. Each wing includes a swing arm movably located in the transmission chamber. A transmission component is also movably located in the pen barrel. The front end of the transmission component is connected to the telescopic locking mechanism or the push button. When the telescopic locking mechanism or the push button drives the extension and retraction of the pen core, it moves along the front-to-back direction of the pen barrel. The rear end of the transmission component is located in the transmission chamber and is driven by the swing arms of the two wings.
[0006] Furthermore, the swing arms of the two wings extend toward the sides of the transmission chamber respectively. The rear end of the transmission component includes a first pushing part and a second pushing part that form a pushing cooperation with the swing arms. The first pushing part is located behind the swing arms, and the second pushing part is located in front of the swing arms. When the transmission component moves back and forth, the first pushing part and the second pushing part push the swing arms to swing in two different directions respectively. The structure is relatively simple, and the swing arms can be inserted between the first pushing part and the second pushing part, making assembly relatively convenient.
[0007] Furthermore, the rotation axes of the two wings are coaxially arranged. The rear end of the transmission component has a connecting cavity. The rear end and both sides of the transmission component are provided with openings communicating with the connecting cavity. The openings on both sides of the transmission component are respectively arranged in the direction of the two sides of the transmission chamber. A gap is left between the inner walls on both sides of the transmission chamber and the two sides of the transmission component to allow the swing arm ends to move. The rear end opening of the transmission component allows the swing arms of the two wings to pass through and be arranged in the connecting cavity. The openings on both sides of the transmission component allow the ends of the swing arms of the two wings to pass through and be arranged in the gap between the inner walls on both sides of the transmission chamber and the two sides of the transmission component. The first and second pushing parts are both arranged in the transmission chamber. During assembly, the ends of the swing arms are sequentially installed through the rear end opening of the transmission component, the transmission chamber, and the side opening of the transmission component. The assembly structure is simple and easy to assemble. The gap between the inner walls on both sides of the transmission chamber and the two sides of the transmission component can increase the swing range of the swing arms and increase the flapping amplitude of the wings.
[0008] Furthermore, one of the wings is provided with a shaft support block, on which a connecting shaft for rotatable connection is provided, and the other wing is provided with a rotating sleeve at a corresponding position. The rotating sleeve and one end of the connecting shaft form a rotating sleeve engagement, which is compact and can easily connect the two wings coaxially together.
[0009] Furthermore, the rear end of the pen barrel is provided with an opening connected to the transmission chamber, and the wings are assembled at the opening. Two bearing seats are provided on the inner edges of both sides of the opening, protruding backward relative to the rear end of the pen barrel. The two bearing seats are respectively connected to the two ends of the connecting shaft in a plug-in rotational fit. The movable toy is shaped like an insect, such as a butterfly. The shaft support block, the rotating sleeve, and the two bearing seats together constitute the main body of the movable toy shaped like an insect. It is long and narrow, and serves as the head, thorax, and abdomen of the insect.
[0010] In other designs, the movable toy can be shaped like a bird or a pterosaur. Alternatively, the rear end of the pen can be designed as the main body of the movable toy.
[0011] Furthermore, the first pushing part is formed by the inner edge of the openings on both sides of the transmission component; the second pushing part is a convex wall located in the middle of the front side wall of the connecting cavity, the end of the convex wall has a wedge-shaped structure, and the lower part of the swing arm has an arc-shaped profile. When the transmission component moves backward, the convex wall, in cooperation with the force applied by the two swing arms, simultaneously pushes the two swing arms to swing.
[0012] Furthermore, a space is formed between the first and second pushing parts for the swing arm to swing between the first and second pushing parts, that is, there is a "free stroke" between the swing arm and the first and second pushing parts. This design can reduce the swing amplitude of the swing arm, which is beneficial to reducing the requirements for the internal space of the pen barrel and making the internal structure of the pen barrel more compact.
[0013] Furthermore, the telescopic locking mechanism includes a front tooth component, a rear tooth component, and a guide rail integrally formed on the inner side of the pen barrel. The front tooth component, the rear tooth component, and the guide rail form a connection that allows them to move back and forth relative to the pen barrel but prevents them from rotating relative to the pen barrel. The rear end of the pen refill abuts against the front tooth component. The rear end of the rear tooth component includes a connecting post. The front end of the transmission component includes a connecting groove that is inserted and fixed to the connecting post. The connecting end of the push button includes a sleeve ring. The sleeve ring is fitted onto the connecting post, and its front and rear ends abut against and limit the rear tooth component and the transmission component.
[0014] The telescopic locking mechanism, consisting of the front tooth component, the rear tooth component, and the guide rail, is very common in push-button pens. It can work with a spring to drive the pen tip to extend from the front end of the pen barrel and keep it in the extended state, or drive the pen tip to retract and return to the pen barrel. The rear tooth component and the transmission component are driven forward by the push button, and the rear tooth component, the push button, and the transmission component move backward under the push of the spring.
[0015] Furthermore, the pen barrel is provided with an elastic element for driving the rear tooth component, push button, or transmission component to move backward and reset. In the above-mentioned telescopic locking mechanism, when the pen tip is in the extended state, the spring pushes the front tooth component to abut against and hold it at the front end of the guide rail via the pen tip. At this time, since the force of the spring is not transmitted to the rear tooth component, push button, and transmission component, these components are in a state where they can move freely back and forth within the pen barrel. The elastic element can push these components, mainly the transmission component, to move backward and reset along the pen barrel, so that the transmission component can drive the wings to flap, which can increase the flapping amplitude of the wings after the pen switches from the retracted state to the extended state.
[0016] The beneficial effects of this utility model are: the toy pen of this utility model has a movable wing structure. When the pen core is extended or retracted by the operating component on the side of the pen barrel, it can be linked with the two wings of the movable toy to flap. The transmission structure between the wings and the operating component is simple and compact, and occupies less internal space at the rear end of the pen barrel. This makes the front and rear diameter of the pen relatively uniform, and thus the appearance is more beautiful. Attached Figure Description

[0026] The structure of the toy pen with movable wings in this embodiment of the utility model is as follows: Figure 1-9As shown, the device includes a pen barrel 1, a telescopic locking mechanism, a push button 2, a pen refill 3, a spring 6, and a movable toy located at the rear end of the pen barrel 1. The spring 6 abuts against the front end of the pen refill 3 and the pen barrel 1. The push button 2 and the pen barrel 1 are connected in a movable manner along the front-back direction of the pen barrel 1. The push button 2 includes a connecting end 21 located in the inner cavity of the pen barrel 1 and an operating end 22 located on the outside of the pen barrel 1. The connecting end 21 of the push button 2 is connected to the telescopic locking mechanism, which is connected to the rear end of the pen refill 3. The push button 2, through the telescopic locking mechanism, links the extension and retraction of the pen refill 3. The movable toy... The toy includes two movable wings 4, which are rotatably mounted at the rear end of the pen barrel 1. The rear end of the inner cavity of the pen barrel 1 includes a transmission chamber 10. Each of the two wings 4 includes a swing arm 41 movably mounted in the transmission chamber 10. A transmission component 5 is also movably mounted in the pen barrel 1. The front end of the transmission component 5 is connected to a telescopic locking mechanism or push button 2. When the telescopic locking mechanism or push button 2 drives the pen core 3 to move in the front-back direction of the pen barrel 1, the rear end of the transmission component 5 is located in the transmission chamber 10 and forms a driving cooperation with the swing arms 41 of the two wings 4.
[0027] The swing arms 41 of the two wings 4 extend obliquely toward the two sides of the transmission chamber 10. The rear end of the transmission component 5 includes a first pushing part 51 and a second pushing part 52 that are in a pushing engagement with the swing arms 41. The first pushing part 51 is located behind the swing arms 41, and the second pushing part 52 is located in front of the swing arms 41. When the transmission component 5 moves back and forth, the first pushing part 51 and the second pushing part 52 push the swing arms 41 to swing in two different directions respectively. The structure is relatively simple and compact. It is easy to assemble as long as the swing arms 41 are inserted between the first pushing part 51 and the second pushing part 52.
[0028] The rotation axes of the two wings 4 are coaxially arranged, resulting in a compact structure. The rear end of the transmission component 5 has a connecting cavity 50. Openings communicating with the connecting cavity 50 are provided at the rear end and on both sides of the transmission component 5. The openings 501 on both sides of the transmission component 5 correspond to the two sides of the transmission chamber 10. A gap is left between the inner walls of both sides of the transmission chamber 10 and the two sides of the transmission component 5 to allow the ends of the swing arms 41 to swing. The rear end opening 502 of the transmission component 5 allows the swing arms 41 of the two wings 4 to pass through and be arranged in the connecting cavity 50. The openings 501 on both sides of the transmission component 5 can... The ends of the swing arms 41 of the two wings 4 are respectively inserted into the gap between the inner walls of the transmission chamber 10 and the two sides of the transmission component 5. The first push part 51 and the second push part 52 are both arranged in the transmission chamber 10. During assembly, the ends of the swing arms 41 are sequentially inserted into the rear end opening 502 of the transmission component 5, the transmission chamber 10, and the side opening 501 of the transmission component 5. The assembly structure is simple and easy to assemble. The gap between the inner walls of the two sides of the transmission chamber 10 and the two sides of the transmission component 5 can increase the swing range of the swing arms 41 and increase the flapping amplitude of the wings 4.
[0029] One of the wings 4 is provided with a shaft support block 42, and a connecting shaft 43 for establishing a rotatable connection between the wings is provided on the shaft support block 42. The other wing 4 is provided with a rotating sleeve 44 at the corresponding position. The rotating sleeve 44 and one end of the connecting shaft 43 form a rotatable sleeve engagement. The structure is compact and can easily connect the two wings 4 coaxially together.
[0030] like Figure 6 , 8 As shown, the rear end of the pen barrel 1 is provided with an opening 11 that connects to the transmission chamber 10. The wings 4 are assembled at the opening 11. Two bearing seats 12 are provided on the inner edges of both sides of the opening 11, protruding rearward relative to the rear end face of the pen barrel 1. The two bearing seats 12 are respectively connected to the two ends of the connecting shaft 43 in a plug-in rotational fit. The movable toy is insect-shaped, for example, butterfly-shaped in this embodiment. The shaft support block 42, the rotating sleeve 44, and the two bearing seats 12 together constitute the main body of the insect-shaped movable toy, which is long and narrow, serving as the head, thorax, and abdomen of the insect, making the structure more compact.
[0031] In other embodiments, the movable toy as a whole can also be shaped like a bird or a pterosaur. In other embodiments, the rear end of the pen barrel 1 can also be shaped as the main body of the movable toy, that is, the rear end of the pen barrel 1 can be used as the main body of the movable toy.
[0032] refer to Figure 7The first pushing part 51 is formed by the inner edge of the two side openings 501 of the transmission component 5; the second pushing part 52 is a convex wall provided in the middle of the front side wall of the connecting cavity 50. The end of the convex wall has a wedge-shaped structure, and the lower part of the swing arm 41 has an arc-shaped profile. When the transmission component 5 moves backward, the convex wall pushes the two swing arms 41 to swing simultaneously by cooperating with the force applied by the two swing arms 41.
[0033] A space is formed between the first pushing part 51 and the second pushing part 52 for the swing arm 41 to swing between the first pushing part 51 and the second pushing part 52. That is, there is a "free stroke" between the swing arm and the first and second pushing parts. This design can reduce the swing amplitude of the swing arm 41, which is beneficial to reduce the requirements on the internal space of the rear end of the pen barrel 1 (i.e., the space of the transmission chamber 10) and make the internal structure of the pen barrel 1 more compact.
[0034] like Figure 2 , 3 As shown in Figures 6 and 7, the telescopic locking mechanism includes a front tooth component 71, a rear tooth component 72, and multiple guide rails (not shown in the figures) evenly distributed circumferentially on the inner wall of the pen barrel 1. The guide rails are integrally formed with the pen barrel 1. The front tooth component 71 and the rear tooth component 72 and the guide rails form a connection that allows them to move back and forth relative to the pen barrel 1 but prevents them from rotating relative to the pen barrel 1. The rear end of the pen refill 3 abuts against the front tooth component 71. The rear end of the rear tooth component 72 includes a connecting post. The front end of the transmission component 5 includes a connecting groove that is inserted and fixed to the connecting post. The connecting end 21 of the push button 2 includes a sleeve ring. The sleeve ring is fitted on the connecting post. Its front and rear ends abut against and limit the rear tooth component 72 and the transmission component 5. When the push button 2 is pushed alternately, it can drive the pen refill 3 to move forward and extend and remain in the extended state, and drive the pen refill 3 to move backward and retract into the pen barrel 1.
[0035] As a further improvement, in other embodiments, the pen barrel 1 is also provided with an elastic element for driving the rear tooth component 72, the push button 2 or the transmission component 5 to move backward. The elastic element is located at the rear end of the pen barrel. The elastic element can also be a spring structure. One end of the elastic element abuts against the inner side of the pen barrel 1, and the other end abuts against the rear tooth component 72, the push button 2 or the transmission component 5.
[0036] Its working principle is as follows: When the pen lead 3 is in the lead-out state, the spring 6 pushes the front tooth component 71 to abut against and hold it at the front end of the guide rail via the pen lead 3. At this time, since the force of the spring 6 is not transmitted to the rear tooth component 72, the push button 2 and the transmission component 5, these components are in a state of free movement back and forth in the pen barrel 1. The elastic element can push these components. The transmission component 5 moves backward along the pen barrel 1 to reset, so that the transmission component 5 can reset to the last position. During the backward reset process, it can also drive the wings to flap, which can increase the flapping amplitude of the wings when the pen switches from the lead-out state to the lead-retracted state, thus improving the flapping effect of the wings.
[0037] It should be noted that, in order to ensure reliable linkage between the transmission component 5 and the swing arm 41, the transmission component 5 and the pen barrel 1 form a limiting fit that prevents relative rotation.
[0038] The specific structure of the telescopic locking mechanism is known technology. Its working principle is as follows: the front tooth component 71 and the rear tooth component 72 cooperate with the guide rail inside the pen barrel 1 for guided movement (via guide grooves on the outer peripheral walls of the front tooth component 71 and the rear tooth component 72). When the push button 2 is pushed, the rear tooth component 72 pushes the front tooth component 71 forward. When the front tooth component 71 disengages from the guide rail, the helical teeth between the front tooth component 71 and the rear tooth component 72 drive the front tooth component 71 to rotate a certain angle, causing the guide groove of the front tooth component 71 to misalign with the guide rail. When the push button 2 is released, the front tooth component... 71 is limited by the front end of the guide rail, keeping the front tooth component 71 in a forward position, corresponding to the position where the pen refill is ejected. When the push button 2 is pushed again, the rear tooth component 72 pushes the front tooth component 71 forward and disengages from the guide rail. The helical tooth part pushes the front tooth component 71 to rotate a certain angle again, so that the guide groove of the front tooth component 71 is aligned with the guide rail. Under the push of the spring 6, the front tooth component 71 retracts back to the rear position, which corresponds to the refill state. During the pen refill ejection and refill process, the transmission component 5 can move back and forth in conjunction, thereby driving the wings 4 to produce a flapping action.
[0039] 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.
