Description

Technical Field

[0001] This application relates to the field of stationery, and in particular to a multi-colored pencil. Background Technology

[0002] A pencil can typically only draw one color, and different pencils are needed to draw different colors. Currently, multi-colored pencils on the market have replaceable leads, allowing users to change the pencil color by replacing the leads. This method not only requires additional accessories but is also relatively cumbersome to change colors. Summary of the Invention

[0003] To facilitate convenient changes in lead color, this application provides a multi-colored pencil.

[0004] This application provides a multi-colored pencil, which adopts the following technical solution:

[0005] A multi-colored pencil includes a pencil shell, a trigger component for controlling the extension and retraction of the lead, and an adjustment component for adjusting the color of the extended pencil. The adjustment component includes an adjustment sleeve rotatably connected to the pencil shell, the adjustment sleeve having at least two lead-receiving cavities containing different colored pencil leads. The trigger component has a triggered state and a non-triggered state. When in the triggered state, the trigger component pushes the pencil lead out of the pencil shell; when in the non-triggered state, the pencil lead retracts into the adjustment sleeve.

[0006] By adopting the above technical solution, when writing the corresponding color, rotate the adjusting sleeve so that the pencil lead of the corresponding color is aligned with the pen outlet hole of the pen shell. Then, operate the trigger component to be in the triggered state. The trigger component pushes the pencil lead out of the pen shell. When not in use, the pencil lead can be put back into the adjusting component.

[0007] Preferably, the pencil lead is a permanent pencil lead.

[0008] By adopting the above technical solution, the pencil lead is set to be permanent so that the length of the pencil lead will not change. Therefore, the triggering component can push the pencil lead the same distance each time.

[0009] Preferably, the pen casing includes a pen tip, the pen tip contains a first magnet, and the end of the permanent pencil lead away from the pen tip is fixed with a second magnet, and the first magnet and the second magnet repel each other.

[0010] By employing the above technical solution, the repulsive force of the first and second magnets causes the permanent pencil lead to move towards the adjusting sleeve. Therefore, when the triggering component is in the untriggered state, the permanent pencil lead will be retracted into the adjusting sleeve.

[0011] Preferably, the adjusting sleeve is provided with at least three lead-receiving cavities, which are evenly distributed along the circumference of the adjusting sleeve. When the first magnet is located at a position equidistant from the two adjacent second magnets, the permanent pencil lead is directly opposite the pen outlet hole of the pencil case.

[0012] By adopting the above technical solution, at least three pencil receiving cavities are evenly distributed to accommodate the eternal pencil lead. This ensures that when the first magnet is located between two adjacent second magnets, even if the angle is slightly off, after the hand leaves the adjusting sleeve, the adjusting sleeve will only reach a balanced force position when the first magnet is located between two adjacent second magnets due to the repulsive magnetic force between the first magnet and the two adjacent second magnets. At this time, the eternal pencil lead is directly facing the pencil outlet hole.

[0013] Preferably, the pen casing includes a pen barrel, and a first annular upper positioning block is formed near the upper end of the pen barrel. The longitudinal section of the first upper positioning block is arc-shaped on the side facing the center of the pen barrel. An upper limit ring is formed below the first upper positioning block inside the pen barrel. The longitudinal section of the upper limit ring is rectangular. The triggering component includes a mounting shell, a pressing component, a force receiving component, a transmitting component, and a spring that applies a reset force located inside the mounting shell. A second upper positioning block is formed near the lower end of the outer side wall of the mounting shell. When the second upper positioning block and the first upper positioning block are engaged, the lower end face of the mounting shell abuts against the upper limit ring.

[0014] By adopting the above technical solution, the pressing component, the force-bearing component, and the transmission component are set inside the mounting shell. Then, the mounting shell is installed into the pen barrel, and the two are snapped together by the cooperation of the first upper positioning block and the second upper positioning block.

[0015] Preferably, a limiting boss is formed on the inner sidewall of the mounting shell near the upper end. At least two guide strips are evenly distributed along the length of the mounting shell below the limiting boss. The lower end face of the pressing member is formed with a pressing groove to accommodate the upper end of the force-bearing member. At least four pressing teeth are formed around the outer side of the lower end of the pressing member. The force-bearing member includes an upper part and a lower part. The outer diameter of the upper part of the force-bearing member is smaller than the inner diameter of the pressing groove, so that the upper part of the force-bearing member can be inserted into the pressing groove. The outer diameter of the lower part of the force-bearing member is adapted to the inner diameter of the pen barrel. Both the upper and lower parts of the force-bearing member are hollow and form a transmission platform inside that abuts against the upper end face of the transmission member. At least two guide grooves adapted to the guide strips are evenly distributed on the outer side of the force-bearing member. At least four inclined force-bearing surfaces are evenly distributed around the outer side of the upper end of the force-bearing member. The lowest point of the spaced inclined force-bearing surfaces is connected to the guide groove.

[0016] By employing the above technical solution, when the Perpetual Pencil Lead needs to extend from the exit hole, the pressing component is pushed downwards until the guide bar disengages from the guide groove and reaches the highest point of the adjacent inclined force-bearing surface. Because the tip of the pressing tooth engages with the inclined force-bearing surface, the force-bearing component rotates after the guide bar and guide groove are no longer constrained. After releasing the pressing component, under the force of the spring, the guide bar engages with the adjacent inclined force-bearing surface. Since the lowest point of this inclined force-bearing surface is not connected to the guide groove, the force-bearing component and the transmission component remain in a pressed state, at which point the Perpetual Pencil Lead extends from the exit hole. When it is necessary to retract the Perpetual Pencil Lead into the pencil case, the pressing component is pushed downwards until the guide bar reaches the highest point of the adjacent inclined force-bearing surface. At this point, the guide bar no longer engages with the force-bearing component, causing it to rotate. After the pressing part is released, under the action of the spring, the guide bar abuts against the adjacent inclined force-bearing surface. Since the lowest point of the inclined force-bearing surface is connected to the guide groove, the guide bar will eventually enter the guide groove. At this time, the pressing part, the force-bearing part, and the transmission part are completely reset, and the eternal pencil lead is put into the pencil case.

[0017] Preferably, the transmission component includes a first transmission rod inserted into the force-bearing component and abutting against the transmission platform surface. The lower end of the first transmission rod is integrally formed with a relay transmission block. The lower end surface of the relay transmission block is formed with a transmission groove for cooperating with a spring. The lower end surface of the relay transmission block near the side is formed with a downwardly extending second transmission rod, which is inserted into a clearance hole on the pen shell.

[0018] By adopting the above technical solution, a transmission groove is set on the lower end face of the relay transmission block to cooperate with the upper end of the positioning spring, and the second transmission rod is inserted into the clearance hole on the pen shell so that the transmission component itself will not rotate.

[0019] Preferably, the pen casing includes a pen barrel and an extension located at the lower end of the pen barrel. The extension includes a connecting part connected to the pen barrel, an extension rod located below the connecting part, and a pen tip connected below the extension rod. The connecting part includes a tubular outer connecting post, an inner connecting post, and a lower connecting piece connecting the lower ends of the outer connecting post and the inner connecting post. An upper sealing connecting piece is provided inside the inner connecting post.

[0020] By adopting the above technical solution, the extension part is connected to the pen barrel. The inner connecting post connects the extension rod and a closed connecting piece is set inside the inner connecting post to cooperate with the lower end of the positioning spring.

[0021] Preferably, the outer connecting post and the inner connecting post have openings on the same side, and side connecting pieces are formed on both sides of the opening to connect the outer connecting post and the inner connecting post. A side sealing connecting piece is formed on the opening side of the inner connecting post to close the inner connecting post. The upper end face of the side sealing connecting piece is flush with the upper end face of the side connecting piece. The upper surface of the upper sealing connecting piece is flush with the upper surface of the side sealing connecting piece. An avoidance hole is formed on the lower connecting piece at the position between the two side connecting pieces.

[0022] By adopting the above technical solution, openings are provided on one side of the outer connecting post and the inner connecting post, and they are connected by side connecting pieces and side sealing connecting pieces. An obstacle hole is positioned between the two side connecting pieces. This arrangement eliminates the need for excessive internal space for the second transmission rod to pass through, allowing for a smaller pen diameter for easier gripping. While the opening makes the inner connecting post structure less complete, the second transmission rod, passing through this opening, prevents the lower end of the spring from detaching from the inner connecting post.

[0023] Preferably, the lower end of the inner wall of the pen barrel is formed with a first annular groove, a second annular groove, and a third annular groove sequentially from bottom to top. The bottom diameter of the first annular groove is larger than that of the second annular groove, which is larger than that of the third annular groove. The first and second annular grooves are connected by a chamfer. A ring-shaped lower positioning block is provided between the second and third annular grooves. The longitudinal section of the lower positioning block is arc-shaped towards the center of the pen barrel, and the minimum diameter of the inner ring of the lower positioning block is smaller than the bottom diameter of the third annular groove. An annular lower extrusion block is formed on the inner wall of the pen barrel above the third annular groove. The longitudinal section of the lower extrusion block is arc-shaped towards the center of the pen barrel. The outer surface of the outer connecting post is formed with a first annular limiting protrusion and a second annular limiting protrusion sequentially from bottom to top. The outer diameter of the first annular limiting protrusion is equal to the bottom diameter of the second annular groove, and the outer diameter of the second annular limiting protrusion is equal to the bottom diameter of the third annular groove. The inner wall of the inner connecting post is formed with a first annular limiting protrusion and a second annular limiting protrusion sequentially from bottom to top. The secondary forming includes a fourth, fifth, and sixth annular groove. The bottom diameter of the fourth annular groove is larger than that of the fifth and sixth annular grooves. The fourth and fifth annular grooves are connected by a chamfer. An annular inner positioning block is provided between the fifth and sixth annular grooves. The longitudinal section of the inner positioning block is arc-shaped towards the center of the inner connecting column, and the inner diameter of the inner positioning block is smaller than the bottom diameter of the sixth annular groove. An annular inner extrusion block is formed on the inner wall of the inner connecting column above the sixth annular groove. The longitudinal section of the inner extrusion block is arc-shaped towards the center of the inner connecting column. The extension rod is tubular and divided into upper and lower parts. The outer diameter of the lower part of the extension rod is equal to the bottom diameter of the fifth annular groove, and the outer diameter of the upper part of the extension rod is equal to the inner diameter of the inner connecting column. A notch is formed on the side of the extension rod. A central annular limiting protrusion is formed on the outer side of the upper part of the extension rod. The outer diameter of the central annular limiting protrusion is equal to the bottom diameter of the sixth annular groove.

[0024] By adopting the above technical solution, the connecting part and the pen shell are installed and connected, and the extension rod is installed and connected to the connecting part.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. When you need to write the corresponding color, rotate the adjusting sleeve so that the pencil lead of the corresponding color is aligned with the pen outlet hole of the pen shell. Then, operate the trigger component to the triggered state. The trigger component pushes the pencil lead out of the pen shell. When you no longer need to use it, you can put the pencil lead back into the adjusting component.

[0027] 2. Set at least three pencil receiving cavities evenly distributed to accommodate the eternal pencil lead, so that when the first magnet is located between two adjacent second magnets, even if the angle is slightly off, after the hand leaves the adjusting sleeve, under the magnetic force of the repulsion between the first magnet and the two adjacent second magnets, the adjusting sleeve will only reach the balanced force position when the first magnet is located between the two adjacent second magnets, at which point the eternal pencil lead is directly opposite the pencil outlet hole.

[0028] 3. An opening is provided on one side of both the outer and inner connecting posts, and they are connected via side connecting pieces and side sealing connecting pieces. An clearance hole is positioned between the two side connecting pieces. This design eliminates the need for excessive internal space for the second transmission rod to pass through, allowing for a smaller pen diameter for easier gripping. While the opening makes the inner connecting post less complete, the second transmission rod passing through it prevents the lower end of the spring from detaching from the inner connecting post.

[0041] The following is combined with Figure 1-11 This application is described in further detail.

[0042] This application discloses a multi-colored pencil. The terms "up", "down", "left" and "right" used in the embodiments are used to describe the relative directions of the positional relationship, and are not restrictions on the positional relationship.

[0043] like Figure 1 As shown, the multi-colored pencil includes a pencil shell 1, a trigger component 2 located inside the pencil shell 1, and an adjustment component 3 for adjusting the pencil color.

[0044] like Figure 2-4As shown, the pen casing 1 includes a pen barrel 4 and an extension 5 located at the lower end of the pen barrel 4. The pen barrel 4 is a hollow tube, with its length along the vertical direction. A first upper positioning block 6 is formed near the upper end of the pen barrel 4, and the longitudinal section of the first upper positioning block 6 is arc-shaped towards the center of the pen barrel 4. An upper limit ring 7 is formed below the first upper positioning block 6 inside the pen barrel 4, and the longitudinal section of the upper limit ring 7 is rectangular. From bottom to top, the lower end of the inner wall of the pen barrel 4 is formed with a first annular groove 8, a second annular groove 9, and a third annular groove 10. The bottom diameter of the first annular groove 8 is larger than the bottom diameter of the second annular groove 9, which is also larger than the bottom diameter of the third annular groove 10. The first annular groove 8 and the second annular groove 9 are connected by a chamfer. A lower annular positioning block 11 is provided between the second annular groove 9 and the third annular groove 10. The longitudinal section of the lower positioning block 11 is arc-shaped towards the center of the pen barrel 4, and the minimum diameter of the inner ring of the lower positioning block 11 is smaller than the bottom diameter of the third annular groove 10. An annular lower extrusion block 12 is formed on the inner wall of the pen barrel 4 above the third annular groove 10. The longitudinal section of the lower extrusion block 12 is arc-shaped on the side facing the center of the pen barrel 4.

[0045] like Figure 5-6 As shown, the extension 5 includes a connecting portion 13 connected to the pen barrel 4, an extension rod 14 located below the connecting portion 13, and a pen tip 15 connected below the extension rod 14. The connecting portion 13 includes a tubular outer connecting post 16, an inner connecting post 17, and a lower connecting piece 18 connecting the lower ends of the outer connecting post 16 and the inner connecting post 17. The upper end of the inner connecting post 17 is higher than the upper end of the outer connecting post 16, and the outer connecting post 16 and the inner connecting post 17 are open on the same side, with side connecting pieces 19 forming on both sides of the opening to connect the outer connecting post 16 and the inner connecting post 17. A side sealing connecting piece 20 is formed on the open side of the inner connecting post 17 to close the inner connecting post 17. The upper end surface of the side sealing connecting piece 20 is flush with the upper end surface of the side sealing connecting piece 19. An upper sealing connecting piece 21 is formed between the upper end of the side sealing connecting piece 20 and the inner connecting post 17. The upper surface of the upper sealing connecting piece 21 is flush with the upper surface of the side sealing connecting piece 20. An clearance hole 22 is formed on the lower connecting piece 18 between the two side connecting pieces 19. The outer diameter of the outer connecting post 16 is larger than the inner diameter of the lower extrusion block 12 but smaller than the inner diameter of the pen barrel 4. From bottom to top, the outer surface of the outer connecting post 16 is formed with a first annular limiting protrusion 23 and a second annular limiting protrusion 24. The outer diameter of the first annular limiting protrusion 23 is equal to the bottom diameter of the second annular groove 9, and the outer diameter of the second annular limiting protrusion 24 is equal to the bottom diameter of the third annular groove 10.

[0046] like Figure 5-6As shown, the inner wall of the inner connecting column 17 is formed with a fourth annular groove 25, a fifth annular groove 26, and a sixth annular groove 27 sequentially from bottom to top. The bottom diameter of the fourth annular groove 25 is larger than that of the fifth annular groove 26, which is also larger than that of the sixth annular groove 27. The fourth annular groove 25 and the fifth annular groove 26 are connected by a chamfer. A ring-shaped inner positioning block 28 is provided between the fifth annular groove 26 and the sixth annular groove 27. The longitudinal section of the inner positioning block 28 is arc-shaped on the side facing the center of the inner connecting column 17, and the inner diameter of the inner positioning block 28 is smaller than the bottom diameter of the sixth annular groove 27. An annular inner extrusion block 29 is formed on the inner wall of the inner connecting column 17 above the sixth annular groove 27. The longitudinal section of the inner extrusion block 29 is arc-shaped on the side facing the center of the inner connecting column 17.

[0047] like Figure 5-6 As shown, the extension rod 14 is tubular and divided into upper and lower parts. The outer diameter of the lower part of the extension rod 14 is equal to the bottom diameter of the fifth annular groove 26, and the outer diameter of the upper part of the extension rod 14 is equal to the inner diameter of the inner connecting post 17. A notch is formed on the side of the extension rod 14. A central annular limiting protrusion 30 is formed on the outer side of the upper part of the extension rod 14, and the outer diameter of the central annular limiting protrusion 30 is equal to the bottom diameter of the sixth annular groove 27. A locking block 31 is formed on the inner wall of the extension rod 14 near the lower end, and a first magnet 32 ​​is embedded inside the extension rod 14 below the locking block 31. The pen tip 15 is located at the lower end of the extension rod 14 and is integrally formed with the extension rod 14. The pen tip 15's pen outlet is offset to the side and directly opposite the clearance hole 22.

[0048] like Figure 7-9 As shown, the trigger assembly 2 includes a mounting shell 33, a pressing member 34, a force-receiving member 35, a transmitting member 36, and a spring 37 located within the mounting shell 33. A second upper positioning block 38 is formed on the outer side wall of the mounting shell 33 near its lower end. When the second upper positioning block 38 engages with the first upper positioning block 6, the lower end face of the mounting shell 33 abuts against the upper limit ring 7. A limiting boss 39 is formed on the inner side wall of the mounting shell 33 near its upper end to prevent the pressing member 34, the force-receiving member 35, and the transmitting member 36 from dislodging from the mounting shell 33. Three guide strips 40 are evenly distributed along the length of the mounting shell 33 below the limiting boss 39 within the mounting shell 33. In the internal cross-sectional view of the mounting shell 33, the lower end face of the guide strips 40 slopes upwards from left to right. The lower end face of the pressing member 34 is formed with a pressing groove 41 to accommodate the upper end of the force-bearing member 35. Six pressing teeth 42 are formed around the outer side of the lower end of the pressing member 34. The lower end face of the pressing teeth 42 is inclined from both sides to the middle. The inclination angles of the two inclined surfaces at the lower end of the pressing teeth 42 are the same, and the tip formed by the intersection of the two inclined surfaces is biased towards the left side of the pressing teeth 42.

[0049] like Figure 7 and Figure 10As shown, the force-receiving component 35 includes an upper part and a lower part. The outer diameter of the upper part of the force-receiving component 35 is smaller than the inner diameter of the pressing groove 41, so that the upper part of the force-receiving component 35 can be inserted into the pressing groove 41. The outer diameter of the lower part of the force-receiving component 35 is adapted to the inner diameter of the pen barrel 4. Both the upper and lower parts of the force-receiving component 35 are hollow, and a transfer platform 43 is formed inside to abut against the upper end face of the transfer component 36. Three guide grooves 44 adapted to the guide strip 40 are evenly distributed on the outer surface of the force-receiving component 35. Six inclined force-receiving surfaces 45 are evenly distributed around the outer surface of the upper end of the force-receiving component 35, and each inclined force-receiving surface 45 is inclined downward from left to right. The lowest point of the spaced inclined force-receiving surfaces 45 is connected to the guide groove 44.

[0050] like Figure 10 As shown, the transmission component 36 includes a first transmission rod 46 inserted into the force-bearing component 35 and abutting against the transmission platform 43. A relay transmission block 47 is integrally formed at the lower end of the first transmission rod 46, and a transmission groove 48 is formed on the lower end surface of the relay transmission block 47. The upper end of the spring 37 is located within the transmission groove 48, and the lower end of the spring 37 abuts against the upper closed connecting piece 21 within the inner connecting post 17. A second transmission rod 49 extending downwards is formed near the side of the lower end surface of the relay transmission block 47, and the second transmission rod 49 is inserted into the clearance hole 22.

[0051] like Figure 11As shown, the adjustment assembly 3 includes a transparent adjustment sleeve 50 fitted onto the extension rod 14. The adjustment sleeve 50 is cylindrical with an outer diameter equal to that of the pen barrel 4. The upper end of the adjustment sleeve 50 abuts against the pen barrel 4, and the lower end of the adjustment sleeve 50 abuts against the pen tip 15. Four partition blocks 51 are evenly distributed on the inner side of the adjustment sleeve 50, and pen refill receiving cavities 52 are formed between adjacent partition blocks 51. The side of the partition block 51 facing the center of the adjustment sleeve 50 has an arc-shaped surface that abuts against the outer surface of the extension rod 14, so that the adjustment sleeve 50 and the extension rod 14 can only rotate relative to the extension rod 14. Each lead-receiving cavity 52 contains a permanent pencil lead 53 of a different color. The diameter of the permanent pencil lead 53 is larger than the diameter of the clearance hole 22. A second magnet 54 of the same diameter is fixed to the upper end of the permanent pencil lead 53. The magnetic poles of the first magnet 32 ​​and the second magnet 54 are the same on their opposite sides. Therefore, the magnetic force of the first magnet 32 ​​pushes the permanent pencil lead 53 upward. When the first magnet 32 ​​is located between two adjacent second magnets 54, one of the permanent pencil leads 53 is directly opposite the clearance hole 22 and the lead outlet hole. When the permanent pencil lead 53 passes through the lead outlet hole, the lower end of the second magnet 54 connected to the permanent pencil lead 53 is always higher than the upper end of the first magnet 32. A through hole is formed on the side of the permanent pencil lead 53 near the lower end. When the lower end of the permanent pencil lead 53 extends out of the lead outlet hole, the through hole also moves out of the lead outlet hole. The Eternal Pencil Lead 53 has an extremely long lifespan and minimal wear and tear during use. When you need to replace the lead with a different color to meet the needs of writing in more colors, simply insert a paperclip or a card ejector tool into the through hole and forcefully pull out the Eternal Pencil Lead to overcome the repulsive force of the magnet. Then, insert another color of Eternal Pencil Lead 53.

[0052] Specific usage process:

[0053] When adjusting the corresponding color of the permanent pencil lead 53, rotate the adjusting sleeve 50 to rotate the corresponding color of the permanent pencil lead 53 to the position directly facing the pencil hole. Even if the angle is slightly off at this time, after the hand leaves the adjusting sleeve 50, under the magnetic force of the repulsion between the first magnet 32 ​​and the two adjacent second magnets 54, the adjusting sleeve 50 will only reach the balanced force position when the first magnet 32 ​​is located in the middle of the two adjacent second magnets 54. At this time, the permanent pencil lead 53 is directly facing the pencil hole.

[0054] When the permanent pencil lead 53 needs to extend from the exit hole, the pressing member 34 is pressed downwards until the guide bar 40 disengages from the guide groove 44 and reaches the highest point of the adjacent inclined force-bearing surface 45. Since the tip of the pressing tooth 42 engages with the inclined force-bearing surface 45, the force-bearing member 35 will rotate after the guide bar 40 and guide groove 44 are no longer restricted. After releasing the pressing member 34, under the force of the spring 37, the guide bar 40 engages with the adjacent inclined force-bearing surface 45. Since the lowest point of the inclined force-bearing surface 45 is not connected to the guide groove 44, the force-bearing member 35 and the transmission member 36 remain in a pressed-down state. At this time, the permanent pencil lead 53 extends from the exit hole.

[0055] When it is necessary to retract the Perpetual Pencil Lead 53 into the Pen Case 1, press the pressing member 34 downwards until the guide bar 40 reaches the highest point of the adjacent inclined force-bearing surface 45. At this point, the guide bar 40 no longer abuts against the force-bearing member 35, and the force-bearing member 35 will rotate. After releasing the pressing member 34, under the force of the spring 37, the guide bar 40 engages with the adjacent inclined force-bearing surface 45. Since the lowest point of the inclined force-bearing surface 45 is connected to the guide groove 44, the guide bar 40 will eventually enter the guide groove 44. At this point, the pressing member 34, the force-bearing member 35, and the transmission member 36 are completely reset, and the Perpetual Pencil Lead 53 is retracted into the Pen Case 1.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
