Description

Technical Field

[0001] This invention relates to the field of pen technology, and in particular to a silent, press-operated pen. Background Technology

[0002] A push-button pen is easy to use and carry, as the lead extends or retracts into the barrel with a simple press, making it very popular. However, traditional push-button pens share a common characteristic: when pressed, the moving parts inside the pen collide, producing a "click-click" sound. This noise can be unpleasant in quiet environments. Summary of the Invention

[0003] The purpose of this invention is to provide a silent click pen to overcome the defect of traditional click pens that make noise when pressed.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a silent pressable pen, comprising: a pen barrel, a pen core installed in the pen barrel, and an elastic component elastically abutting against the pen core, wherein a pressable telescopic mechanism is installed between the pen barrel and the pen core, and the pressable telescopic mechanism cooperates with the elastic component when pressed to drive the pen core to move up and down in the pen barrel;

[0005] The press-and-retract mechanism includes a press core and a rotating wheel. The press core is slidably positioned within the pen barrel and has a guide rail connected end to end on its outer circumference. The top of the pen refill rests against the bottom of the press core. The rotating wheel is rotatably mounted on the press core and has a slider on its inner wall. The slider extends into the guide rail and can move unidirectionally along the guide rail when the press core is pressed.

[0006] The guide rail has a home position and a locking position. When the slider is in the home position, the pen tip is in a retracted state; when the slider is in the locking position, the pen tip is in a writing state.

[0007] As a further improvement of the present invention, the press core is recessed inward along the outer circumference to form a groove, and a stop block that is not connected to the inner wall of the groove is provided in the middle of the groove, thereby forming the guide track around the outer side of the stop block.

[0008] As a further improvement of the present invention, the guide rail also has an extended high point and a retracted high point, the extended high point and the retracted high point being located on both sides above the locking position, respectively.

[0009] When the presser applies pressure, the slider located in the original position can slide relative to the guide rail to the extended high point. After the pressure is released, under the elastic force of the elastic component, the presser moves upward, causing the slider to fall from the extended high point into the locking position.

[0010] When the presser applies pressure, it can cause the slider located in the locked position to slide relative to the guide rail to the retraction high point. After the pressing pressure is released, under the elastic force of the elastic component, the presser moves upward, causing the slider to return from the retraction high point to its original position.

[0011] As a further improvement of the present invention, the stop block has a first guide surface and a second guide surface, and the inner wall of the groove has a third guide surface, a fourth guide surface and a fifth guide surface;

[0012] The first guide surface is disposed opposite to the original position, the third guide surface is located above the end of the first guide surface, and the end of the third guide surface extends to the protruding high point. The first guide surface is used to guide the slider to the third guide surface, and the third guide surface is used to guide the slider to the protruding high point.

[0013] The second guide surface is disposed opposite to the protruding high point, and its end extends to the locking position. The second guide surface is used to guide the slider to the locking position.

[0014] The fourth guide surface is disposed opposite to the locking position, and its end extends to the retraction high point. The fourth guide surface is used to guide the slider to the retraction high point.

[0015] The fifth guide surface is positioned opposite to the retraction high point, and its end extends to the original position. The fifth guide surface is used to guide the slider to the original position.

[0016] As a further improvement of the present invention, two guide rails are provided, and the two guide rails are centrally symmetrically distributed on the outer peripheral surface of the press core; correspondingly, the rotating wheel is provided with two sliders.

[0017] As a further improvement of the present invention, the push-to-retract mechanism further includes a stop wheel, which is fixed inside the pen barrel and fitted on the outside of the press core. The stop wheel is provided with a stop plate, and the pen core pushes the press core upward and stops on the stop plate under the elastic force of the elastic component.

[0018] As a further improvement of the present invention, the upper end of the press core is provided with a pressing rod, the pressing rod passes through the stop wheel and protrudes from the top of the pen barrel; the pressing rod is provided with at least one limiting groove along the axial direction, and the stop wheel is provided with a protrusion along its inner wall, the protrusion slidingly engaging in the limiting groove.

[0019] As a further improvement of the present invention, the pen barrel is provided with an annular boss along the inner wall, and the rotating wheel is limited between the bottom of the annular boss and the stop wheel.

[0020] As a further improvement of the present invention, the press core is provided with a funnel-shaped track slide entrance at its lower end, and the track slide entrance is connected to the original position of the guide track.

[0021] As a further improvement of the present invention, the slider is rhomboid in shape.

[0022] The beneficial effects of this invention are as follows: This invention provides a silent press-action pen, in which a core and a rotating wheel are installed inside the pen barrel. A guide rail is provided on the outer circumferential surface of the core, and the rotating wheel is rotatably mounted on the core. A slider extending into the guide rail is provided on the rotating wheel. The slider can move along the guide rail to the locked position and the original position when the core is pressed, so as to realize the extension or retraction of the pen core into the pen barrel, thereby preventing noise due to collision and achieving a silent effect. At the same time, this structural design also has the advantages of simple structure, convenient assembly of various parts, low manufacturing cost, high product stability, and good user feel. Moreover, the press-action pen can be made finer. Attached Figure Description

Detailed Implementation

[0040] The preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0041] See Figures 1 to 13This invention provides a silent, clickable pen, comprising: a pen barrel 1, a pen refill 2, an elastic component 3, and a click-and-retract mechanism. The pen barrel 1 includes an upper pen shell and a lower pen shell. The upper pen shell is a hollow tube, and the upper end of the lower pen shell is threaded onto the upper pen shell, with a tapered head at its lower end. The pen refill 2 is installed in the inner cavity of the pen barrel 1, and the tip of the pen refill 2 is located within the tapered head of the lower pen shell. The elastic component 3 is a spring, fitted onto the tip of the pen refill 2. The diameter of the pen refill 2 decreases near the tip, forming a first stepped surface with the body of the pen refill 2. The upper end of the elastic component 3 elastically abuts against this stepped surface, and the lower end of the elastic component 3 elastically abuts against the inside of the tapered head of the lower pen shell. The click-and-retract mechanism is disposed between the pen barrel 1 and the pen refill 2. When pressed, the click-and-retract mechanism cooperates with the elastic component 3 to drive the pen refill 2 to move up and down within the pen barrel 1.

[0042] See Figures 2 to 4 The telescopic mechanism includes a presser 4, a rotating wheel 5, and a stop wheel 6. The presser 4 is slidably limited within the pen barrel 1, and the top of the pen refill 2 rests against the bottom of the presser 4. The rotating wheel 5 and the stop wheel 6 are both annular and are fitted onto the presser 4.

[0043] Among them, the pen barrel 1 is provided with an arc-shaped rib along the inner wall of the stop wheel 6, and the stop wheel 6 is provided with an arc-shaped groove along the outer wall. The stop wheel 6 is fixed to the pen barrel 1 by the arc-shaped groove and the arc-shaped rib in a tight fit.

[0044] The pen barrel 1 has an annular boss 101 along its inner wall, and the rotating wheel 5 is placed on the annular boss 101 and has a clearance fit with the inner circumferential wall of the pen barrel 1. In addition, the rotating wheel 5 is located below the stop wheel 6, and there is a certain gap between the top of the rotating wheel 5 and the bottom of the stop wheel 6, so as to limit the rotating wheel 5 between the annular boss 101 and the bottom of the stop wheel 6, without affecting the rotating motion of the rotating wheel 5.

[0045] See Figure 2 and Figure 7 An actuating rod 403 extends integrally upward from the center of the upper end face of the presser 4. The actuating rod 403 passes through the stop wheel 6 and protrudes from the top of the pen barrel 1 for easy pressing. The diameter of the actuating rod 403 is smaller than the diameter of the presser 4 body, thus forming a second stepped surface between the presser 4 body and the actuating rod 403. The upper end of the stop wheel 6 extends towards the center to form an annular stop 601. Under the elastic force of the elastic member 3, the pen lead 2 pushes the presser 4 upward, and stops and limits it on the bottom surface of the stop 601 through its second stepped surface.

[0046] See Figure 4 and Figure 7The push rod 403 has two symmetrical limiting grooves 4031 along the axial direction. The annular stop 601 has two protrusions 602 along its inner circumferential wall corresponding to the two limiting grooves 4031. The two protrusions 602 extend into the corresponding limiting grooves 4031. The press core 4 slides with the protrusions 602 through the limiting grooves 4031 to prevent the press core 4 from rotating. The press core 4 can only move vertically up and down.

[0047] See Figure 5 and Figure 6 The outer circumference of the press core 4 is provided with a guide rail 401 connected end to end along the vertical direction. The inner wall of the rotating wheel 5 is integrally formed with a slider 501, which extends into the guide rail 401. The slider 501 can move unidirectionally along the guide rail 401 when the press core 4 is pressed.

[0048] Specifically, the press core 4 is recessed inward along its outer periphery to form a groove, the contour shape of which satisfies the motion trajectory requirements of the slider 501; in addition, the press core 4 is provided with a stop block 402 in the middle of the groove that is not connected to the inner wall of the groove, thereby forming a guide track 401 around the outside of the stop block 402.

[0049] Furthermore, the guide rail 401 has a home position 4011, a locking position 4012, an extended high point position 4013, and a retracted high point position 4014. The home position 4011 is located at the bottom of the guide rail 401, the locking position 4012 is located on the stop block 402, and the extended high point position 4013 and the retracted high point position 4014 are located on the upper sides of the locking position 4012, respectively. When the slider 501 is in the home position 4011 (e.g....), Figure 8 As shown), the pen refill 2 is in the retracted state. When the presser 4 applies pressure, as the presser 4 moves the pen refill 2 downwards, the slider 501, located in its original position 4011, slides relative to the guide rail 401 (as shown). Figure 9 As shown), this will cause the rotating wheel 5 to rotate until the slider 501 reaches the extended high point 4013 (as shown). Figure 10 As shown), and during this process, the elastic component 3 is compressed to store energy; after the pressure is released, under the elastic force of the elastic component 3, the pen lead 2 pushes the press lead 4 upward, causing the slider 501 to fall from the extended high point 4013 into the locking position 4012 (as shown). Figure 11 As shown), the pen refill 2 is in writing mode. When the presser 4 applies pressure again, as the presser 4 moves the pen refill 2 downwards, the slider 501, located in the locking position 4012, slides relative to the guide rail 401, causing the rotating wheel 5 to rotate until the slider 501 reaches the retraction high point 4014 (as shown). Figure 12As shown), the elastic component 3 is compressed to store energy; after the pressure is released, under the elastic force of the elastic component 3, the pen lead 2 pushes the press lead 4 upward, causing the slider 501 to slide relative to the guide rail 401 (as shown). Figure 13 As shown), it returns from the high point 4014 to the original position 4011.

[0050] For further details, please refer to [link / reference]. Figure 5 The stop block 402 is shaped like a downward-pointing arrow. The stop block 402 has a first tip 4023 on the left, a second tip 4024 on the right, a third tip 4025 at the bottom, and a V-shaped groove between the first and second tips. The tip of this V-shaped groove is the location of the locking position 4012. The surface on the stop block 402 connecting the second tip 4024 and the third tip 4025 is the first guide surface 4021, and the surface connecting the second tip 4024 and the locking position 4012 is the second guide surface 4022. The inner wall of the groove of the snap-fit ​​4 has a third guide surface 4015, a fourth guide surface 4016, and a fifth guide surface 4017.

[0051] The following provides a detailed description of each guide surface.

[0052] by Figure 5 For reference, the first guide surface 4021 is located on the lower right side of the stop block 402 and is arranged at an upward inclination. The first end of the first guide surface 4021 is on the third tip 4025, and the last end of the first guide surface 4021 is on the second tip 4024, with the last end higher than the first end. It should be noted that the direction from the first end to the last end, as defined in this application, is consistent with the direction of movement of the slider 501 along the guide track 401 (counterclockwise), and the same applies below. The first guide surface 4021 is set opposite to the original position 4011, meaning that the original position 4011 can be vertically projected upward onto the first guide surface 4021. It should be emphasized that the vertical plane where the original position 4011 is located is offset to the right compared to the vertical plane where the third tip 4025 is located. When the presser 4 is pressed, during the initial downward movement of the presser 4, the rotating wheel 5 does not rotate because it slides vertically along the guide rail 401. To ensure that the slider 501 can smoothly slide from its original position 4011 to the first guide surface 4021, the original position 4011 needs to be offset to the right relative to the third tip 4025. When the slider 501 slides onto the first guide surface 4021 and continues to slide relative to it during the subsequent movement, the slider 501, pushed by the first guide surface 4021, causes the rotating wheel 5 to rotate.

[0053] The third guide surface 4015 is located above the end of the first guide surface 4021 (in other words, the second tip 4024), meaning that the end of the first guide surface 4021 can be projected vertically upwards onto the third guide surface 4015. The third guide surface 4015 is arranged at an upward inclination, with its end higher than its beginning end, and its end extending to the high point 4013. During the downward movement of the presser core 4, the first guide surface 4021 can guide the slider 501 to the third guide surface 4015, and then the third guide surface 4015 guides the slider 501 to the high point 4013.

[0054] The second guide surface 4022 is positioned opposite to the extended high point 4013 and is located below the extended high point 4013. The second guide surface 4022 is arranged at a downward inclination, with its first end on the second tip 4024 and its last end extending to the locking position 4012. The last end of the second guide surface 4022 is lower than its first end. It should be emphasized that the vertical plane where the extended high point 4013 is located is offset to the left relative to the vertical plane where the second tip 4024 is located. After the pressure is released, during the initial distance when the elastic component 3 drives the pen tip 2 to push the press tip 4 upward, the rotating wheel 5 will not rotate during this process because it slides relatively vertically along the guide rail 401. In order to ensure that the slider 501 can smoothly slide from the extended high point 4013 to the second guide surface 4022, the extended high point 4013 needs to be set to be offset to the left relative to the second tip 4024. When the slider 501 slides onto the second guide surface 4022 and continues to slide relative to it during the subsequent movement, it is guided by the second guide surface 4022 to the locking position 4012; during this sliding process, the slider 501 causes the rotating wheel 5 to rotate under the push of the second guide surface 4022.

[0055] The fourth guide surface 4016 is positioned opposite the locking position 4012 and is located above the locking position 4012. The fourth guide surface 4016 is arranged at an upward inclination, with its end higher than its beginning end, and its end extending to the retracted high point 4014. It should be emphasized that the vertical plane where the locking position 4012 is located is offset to the left relative to the vertical plane where the extended high point 4013 is located, and the locking position 4012 can be vertically projected onto the fourth guide surface 4016. When the presser 4 is pressed again, during the initial downward movement of the presser 4, the rotating wheel 5 will not rotate because it slides relatively vertically along the guide rail 401. In order to ensure that the slider 501 can smoothly slide from the locking position 4012 to the fourth guide surface 4016, the locking position 4012 needs to be set to be offset to the left relative to the extended high point 4013 to prevent the slider 501 from sliding back to the extended high point 4013. When the slider 501 slides onto the fourth guide surface 4016 and continues to slide relative to it during the subsequent movement, it is guided by the fourth guide surface 4016 to the retraction high point 4014. During this sliding process, the slider 501 is pushed by the fourth guide surface 4016, causing the rotating wheel 5 to rotate.

[0056] The fifth guide surface 4017 is positioned opposite the retraction high point 4014 and is located below the retraction high point 4014. In this embodiment, the fifth guide surface 4017 is composed of a first inclined surface and a second inclined surface that are connected to each other. Both the first and second inclined surfaces are arranged at a downward inclination, and the end of the second inclined surface extends to the original position 4011. It should be emphasized that the vertical surface where the retraction high point 4014 is located is offset to the left compared to the vertical surface where the first tip 4023 is located, and the retraction high point 4014 can be vertically projected downward onto the first inclined surface. When the pressure is released again, the elastic component 3 drives the pen tip 2 to push the presser 4 upward for an initial distance. During this process, the wheel 5 does not rotate because it slides relatively vertically along the guide rail 401. To ensure that the slider 501 can smoothly slide from the retraction high point 4014 to the first inclined plane, the retraction high point 4014 needs to be offset to the left relative to the first tip 4023 to prevent the first tip 4023 from obstructing the slider 501. When the slider 501 slides to the first inclined plane, it transitions from the first inclined plane to the second inclined plane, and finally, the second inclined plane guides the slider 501 back to its original position 4011. Alternatively, the fifth guide surface 4017 can also be a downwardly sloping curved surface, with its end extending to the original position 4011, achieving the same technical effect.

[0057] It should be noted that during the process of slider 501 sliding relative to each point to the corresponding guide surface within guide rail 401, although there will be collisions, the collisions are not enough to produce a sound. This is because the stroke of slider 501 from each point to the corresponding guide surface is very small, and each guide surface is an inclined plane. When slider 501 falls onto the corresponding guide surface, it will slide directly along the inclined plane. In addition, the speed at which the hand presses the button 4 is not very fast, and when the press is released, the hand cannot instantly release the button 4, thus achieving a silent effect.

[0058] Two guide rails 401 are provided, and the two guide rails 401 are centrally symmetrically distributed on the outer circumference of the press core 4. Correspondingly, the rotating wheel 5 is provided with two sliders 501, which extend into the two guide rails 401 one by one, which can improve the stability of the movement of each component.

[0059] Furthermore, the presser 4 has two track inlets 404 at its lower end corresponding to the two guide rails 401. The track inlets 404 are funnel-shaped, wider at the bottom and narrower at the top, and are connected one-to-one with the original positions 4011 of the guide rails 401. During assembly, the rotating wheel 5 is first placed inside the pen barrel 1, and then the presser 4 is directly inserted above the rotating wheel 5, so that the slider 501 on the rotating wheel 5 slides along the track inlets 404 to its original position 4011, making assembly very convenient.

[0060] See Figure 15 The slider 501 is rhomboid in shape, with chamfered corners at both its top and bottom. These two corners are on the same vertical plane. The slider 501 slides on the guide surfaces using these corners, resulting in a smaller contact area and smoother sliding. Furthermore, during the process of the pen refill 2 moving from the writing state to the retracted state, pressing the button 4 does not require the entire slider 501 to completely pass over the first tip 4023. Only after ensuring that the bottom corner of the slider 501 passes over the first tip 4023 is the button 4 released. As the elastic component 3 drives the pen refill 2 to push the button 4 upwards, the first tip 4023 contacts one of the inclined surfaces of the slider 501 (e.g., ...). Figure 14 As shown), the slider 501 is pushed to slide along the guide rail 401. Therefore, the use of a diamond-shaped slider 501 allows the guide rail 401 of the press core 4 to have a smaller rotation angle, thus making the press pen finer and also reducing the stroke of the pen core 2.

[0061] Therefore, the present invention provides a silent press-action pen. A press core 4 and a rotating wheel 5 are installed inside the pen barrel 1. A guide rail 401 is provided on the outer circumferential surface of the press core 4. The rotating wheel 5 is rotatably mounted on the press core 4, and a slider 501 extending into the guide rail 401 is provided on the rotating wheel 5. When the press core 4 is pressed, the slider 501 can move along the guide rail 401 to the locking position 4012 and the original position 4011, so as to realize the extension or retraction of the pen core 2 into the pen barrel 1, thereby preventing noise caused by collision and achieving a silent effect. At the same time, the structural design of this application also has the advantages of simple structure, convenient assembly of various parts, low manufacturing cost, high product stability and good user feel. Moreover, the press-action pen can be made finer.
