Description
Technical Field
[0001] The utility model relates to the technical field of pens, and more specifically to a multi-purpose pen. Background Art
[0002] Fountain pen manufacturers will mark the size and type of the nib on the pen. Generally, those marked EF, F, M, B, and BB are standard nibs. Existing fountain pens generally use a single-sized nib. There are five common nib sizes, from thin to thick: EF = XF = Extra Fine, the nib width is about 0.24mm ~ 0.28mm, and the writing thickness is about 0.38mm-0.45mm; F = Fine, the nib width is about 0.28mm ~ 0.34mm, and the writing thickness is about: 0.5mm-0.65mm; M = Medium, the nib width is about, 0.34mm ~ 0.44mm, and the writing thickness is about 0.7mm-0.85mm; B = Broad, the nib width is about 0.44mm ~ 0.54mm, and the writing thickness is about 0.9mm; BB = Double Broad, the nib width is about 0.66mm ~ 0.86mm, and the writing thickness is about 1.2mm or more.
[0003] Some manufacturers have more specialized nibs, such as the EEF nib which is thinner than EF, the 3B (TripleBroad) nib which is thicker than BB, and the MF nib which is between F and M. Although the definition of nib size varies from brand to brand, for example, the M nib of the M brand may sound thicker or thinner than the M nib of the P brand, the width of the nib is mostly between 0.18mm and 0.86mm.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0038] like Figures 1 to 11 As shown, the embodiment of the utility model discloses a multi-purpose fountain pen, including a shell 10, a refill 20, a nib assembly 30 and an adjustment assembly 40. The shell 10 is a hollow cylindrical structure. The refill 20 includes a tongue 21. The tongue 21 is placed at the end of the refill 20. The nib assembly 30 is placed on the tongue 21. One end of the refill 20 is clamped in the shell 10 by a tight fit, and the end of the refill 20 protrudes out of the shell 10 to facilitate the writing operation of the nib assembly 30. Alternatively, the refill 20 can also be fixed in the shell 10 by a snap-fit method.
[0039] The nib assembly 30 includes a detachable first nib 31 and a second nib 32. The first nib 31 and the second nib 32 are combined to realize the writing function of the nib assembly 30. The adjustment assembly 40 is fixed on the shell 10 and connected to the nib assembly 30. The adjustment assembly 40 is used to adjust the distance between the tips of the first nib 31 and the second nib 32, thereby controlling the width of the handwriting of the nib assembly 30, thereby meeting the writing requirements corresponding to nibs of different thicknesses.
[0040] Specifically, the first nib 31 is a fixed nib, the second nib 32 is a movable nib, the adjustment component 40 is connected to the second nib 32, and the adjustment component 40 is used to drive the second nib 32 to move to adjust the tip distance between the first nib 31 and the second nib 32, thereby achieving control of the width of the handwriting of the nib component 30, thereby meeting the writing requirements corresponding to nibs of different thicknesses; in this embodiment, the first nib 31 is fixed on the pen core 20, and the second nib 32 is movably arranged on the pen core 20, thereby facilitating the adjustment operation of the tip distance between the first nib 31 and the second nib 32.
[0041] In one embodiment, the adjustment component 40 includes an adjustment ring 41 and a stopper 42, the stopper 42 is used to limit the adjustment ring 41 to prevent the adjustment ring 41 from rotating synchronously with the rotation of the shell 10, and then limit the movement direction of the adjustment ring 41 within the limit range controlled by the stopper 42, so that the movement direction of the adjustment ring 41 is toward the direction of the second pen tip 32; specifically, the stopper 42 is a circular ring structure, the adjustment ring 41 includes a circular ring portion 411 and an adjustment rod 412, a threaded portion is provided on the outer side of the circular ring portion 411, the circular ring portion 411 is threadedly connected to the inner side of the shell 10, the adjustment rod 412 extends from the circular ring portion 411, and an adjustment convex portion 413 is convexly provided at the end of the adjustment rod 412 toward the second pen tip 32, and the second pen tip 3 2 is provided with a slide groove 301, the adjusting protrusion 413 is stuck in the slide groove 301, and the slide groove 301 is set towards the end of the second pen tip 32, so as to provide a space for the adjusting protrusion 413 to move toward the end of the second pen tip 32, so as to avoid that the adjusting protrusion 413 moves downward and drives the second pen tip 32 to move downward synchronously, thereby affecting the use effect of the pen tip assembly 30; the limit plug 42 is stuck at the lower end opening of the shell 10, and the limit plug 42 and the shell 10 can be rotated with each other. A limit groove 421 is provided on the inner side of the limit plug 42, and the direction of the limit groove 421 is consistent with the direction of the adjusting rod 412. The adjusting rod 412 is placed in the limit groove 421, and the pen tip assembly 30 is arranged on the outside of the limit groove 421, and will not be affected by the limiting position of the limit groove 421.
[0042] The housing 10 is rotated to realize the relative movement between the housing 10 and the annular portion 411, so that the annular portion 411 moves toward the second pen tip 32. Specifically, when the housing 10 rotates, the annular portion 411 and the adjusting rod 412 also rotate together until the adjusting rod 412 is close to the side of the limiting groove 421 of the limiting plug 42. At this time, the adjusting rod 412 cannot deflect under the limiting action of the limiting groove 421, and can only move upward or downward relative to the housing 10. For example, when the housing 10 rotates clockwise and the housing 10 moves upward relative to the adjusting rod 412, since the pen core 20 is tightly connected to the housing 10, the pen core 20 also moves upward relative to the adjusting rod 412, and the pen core 20 is also rotating clockwise. The adjusting rod 412 will not rotate synchronously when the pen core 20 rotates clockwise. As the housing 10 continues to rotate, the second pen tip 32 will no longer rotate under the limiting action of the adjusting protrusion 413 of the adjusting rod 412. Since the first pen tip 31 rotates with the As the housing 10 continues to rotate, the first nib 31 moves in a direction away from the second nib 32, thereby increasing the distance between the tips of the first nib 31 and the second nib 32. Similarly, taking the counterclockwise rotation of the housing 10 and the downward movement of the housing 10 relative to the adjusting rod 412 as an example, since the refill 20 is tightly fitted with the housing 10, the refill 20 also moves downward relative to the adjusting rod 412, and the refill 20 is also rotating counterclockwise. The adjusting rod 412 will not rotate synchronously when the refill 20 rotates counterclockwise. As the housing 10 continues to rotate, the second nib 32 no longer rotates under the limiting action of the adjusting protrusion 413 of the adjusting rod 412. Since the first nib 31 continues to rotate with the housing 10, the first nib 31 moves in a direction close to the second nib 32, thereby decreasing the distance between the tips of the first nib 31 and the second nib 32, thereby controlling the width of the handwriting of the nib assembly 30, thereby meeting the writing requirements corresponding to nibs of different thicknesses.
[0043] Specifically, the direction of the slide groove 301, the direction of the adjustment rod 412 and the direction of the groove wall of the limiting groove 421 are consistent. When the shell 10 is rotated to realize the downward movement of the annular portion 411, since the adjustment rod 412 is limited by the limiting groove 421 of the limiting plug 42 and will not rotate, the shell 10 is in a continuous rotation state relative to the annular portion 411 and the adjustment rod 412. Since the pen core 20 is fixed in the shell 10, the adjustment protrusion 413 of the adjustment rod 412 is stuck in the slide groove 301 of the second pen tip 32, the second pen tip 32 stops rotating, and the first pen tip 31 continues to rotate with the shell 10, so that the first pen tip 31 and the second pen tip 32 are separated, thereby achieving the effect of increasing the tip distance between the second pen tip 32 and the first pen tip 31. This makes the handwriting of the pen tip assembly 30 wider; similarly, when the shell 10 is rotated to realize the upward movement of the annular portion 411, since the adjusting rod 412 is limited by the limiting groove 421 of the limiting plug 42 and will not rotate, the shell 10 is in a continuous rotation state relative to the annular portion 411 and the adjusting rod 412. Since the pen core 20 is fixed in the shell 10, the adjusting protrusion 413 of the adjusting rod 412 is stuck in the slide groove 301 of the second pen tip 32, the second pen tip 32 stops rotating, and the first pen tip 31 continues to rotate with the shell 10, so that the first pen tip 31 and the second pen tip 32 are close to each other, thereby achieving the effect of reducing the tip distance between the second pen tip 32 and the first pen tip 31, so that the handwriting written by the pen tip assembly 30 becomes narrower.
[0044] In this embodiment, the direction of the slide groove 301, the direction of the adjusting rod 412 and the direction of the groove wall of the limiting groove 421 are all consistent with the direction of the tip of the pen tip assembly 30, that is, the direction of the slide groove 301, the direction of the adjusting rod 412 and the direction of the groove wall of the limiting groove 421 are all set vertically downward; in other embodiments, the direction of the slide groove 301, the direction of the adjusting rod 412 and the direction of the groove wall of the limiting groove 421 can all be set obliquely, which shall be subject to the specific manufacturing requirements of the product and will not be elaborated here.
[0045] In one embodiment, a limiting groove 211 is provided on the pen tongue 21, and the width of the limiting groove 211 is greater than the width of the slide groove 301. The adjusting protrusion 413 passes through the slide groove 301 and is placed in the limiting groove 211. The limiting groove 211 is used to limit the lateral movement displacement of the adjusting protrusion 413 relative to the first pen tip 31, thereby ensuring that the rotation angle of the shell 10 is not too large to prevent the second pen tip 32 from falling off the pen tongue 21, thereby effectively ensuring the use effect of the product.
[0046] In one embodiment, the annular portion 411 is provided with a guide column 414 protruding inward, and a guide groove 22 is provided on the pen core 20. The guide column 414 is clamped in the guide groove 22. When the annular portion 411 and the shell 10 move relative to each other, the guide column 414 moves back and forth along the direction of the guide groove 22, further improving the fixing effect of the adjustment component 40, thereby improving the stability of the pen product structure.
[0047] In one embodiment, the first nib 31 includes a first nib portion 311 and a first card 312 bent and extended from the side of the first nib 31, the first card 312 is placed below the rear end surface of the tongue 21, and the first card 312 cooperates with the first nib portion 311 to cover one side of the tongue 21; the second nib 32 includes a second nib portion 321 and a second card 322 bent and extended from the side of the second nib 32, the slide groove 301 is opened on the second nib portion 321, the second card 322 is placed below the rear end surface of the tongue 21, and the second card 322 cooperates with the second nib portion 321 to cover the other side of the tongue 21, thereby achieving the effect of clamping the first nib 31 and the second nib 32 on the tongue 21.
[0048] Furthermore, a third card 313 is extended from the end of the first card 312 , and the tongue 21 is matched with the third card 313 to be provided with a first card slot 212 , and the third card 313 is placed in the first card slot 212 , so that the first nib 31 is firmly fixed on the tongue 21 .
[0049] In one embodiment, the first pen tip 31 also includes a fourth card 314 bent and extended from the first pen tip portion 311, the fourth card 314 is placed on one side of the pen tongue 21, a fifth card 315 is provided on the upper end of the fourth card 314, a second card slot 213 is provided on the upper end of the pen tongue 21 to match the fifth card 315, and the fifth card 315 is placed in the second card slot 213, thereby further ensuring the stability of the first pen tip 31 fixed on the pen tongue 21.
[0050] In one embodiment, the second nib 32 further includes a sixth card 323 bent and extended from the second nib portion 321, the sixth card 323 is placed on the other side of the tongue 21, a seventh card 324 is provided on the upper end of the sixth card 323, a third card slot 214 is provided on the upper end of the tongue 21 to match the seventh card 324, and the seventh card 324 is placed in the third card slot 214, thereby further ensuring the stability of the second nib 32 placed on the tongue 21; wherein the third card slot 214 is provided on the side of the tongue 21, thereby facilitating the displacement of the seventh card 324 in the third card slot 214, thereby ensuring the adjustment effect of the distance between the tips of the second nib 32 and the first nib 31.
[0051] In one embodiment, a vent hole 11 is provided at the upper end of the shell 10, and a sealing cover 50 is provided at the upper end of the shell 10 to match the vent hole 11. The sealing cover 50 is a cylindrical structure, and a sealing plug 51 is fixedly provided inside the sealing cover 50. The sealing plug 51 is clamped in the vent hole 11, thereby sealing the upper end of the shell 10 to prevent external air from entering the shell 10 through the upper end of the shell 10 and affecting the use effect of the ink in the pen core 20; in addition, if it is necessary to add ink to the pen core 20, it is only necessary to separate the sealing cover 50 from the upper end of the shell 10 and inject the external ink into the pen core 20 in the shell 10 to realize the ink adding operation, thereby enhancing the practicality of the utility model.
[0052] like Figure 12 to Figure 14 As shown, alternatively, the shell 10 includes an upper shell 101 and a lower shell 102, the annular portion 411 is threadedly connected to the inner side of the lower shell 102, the pen core 20 also includes a thick core portion 201 and a thin core portion 202 that are integrally connected, the pen tongue 21 is arranged at the end of the thin core portion 202, and a limiting ring portion 203 is arranged at the connection between the thick core portion 201 and the thin core portion 202, an elastic ring column 1021 is arranged at one end of the lower shell 102 facing the thick core portion 201, the thin core portion 202 is placed in the elastic ring column 1021, and the end of the elastic ring column 1021 is abutted against the limiting ring portion 203, and a limiting convex portion 1022 is convexly provided on one side of the elastic ring column 1021, and the outer diameter of the limiting convex portion 1022 is greater than the cross-sectional diameter of the thick core portion 201, a convex ring portion 1011 is arranged on the inner side of the upper shell 101, and the lower shell When the body 102 is docked with the upper shell 101, the limiting protrusion 1022 is set through the convex ring part 1011, so that the upper shell 101 and the lower shell 102 are perfectly docked and fixed, so that the thick core part 201 is firmly fixed in the upper shell 101, and the pen core 20 is firmly fixed in the shell 10; specifically, a pressing part (not shown) is provided at the upper end of the upper shell 101, and the thick core part 201 is placed in the hollow cavity of the upper shell 101. The lower end of the thick core part 201, i.e., the limiting ring part 203, is abutted against the elastic ring column 1021, and the upper end of the thick core part 201 is abutted against the pressing part, thereby completing the effect of firmly fixing the thick core part 201 in the upper shell 101, thereby preventing the pen core 20 from rotating in the shell 10 due to external force.
[0053] The lower shell 102 is rotated to realize the relative movement between the lower shell 102 and the annular portion 411, so that the annular portion 411 moves toward the second pen tip 32; specifically, when the lower shell 102 is rotated, the annular portion 411 and the adjustment rod 412 are also rotated together until the adjustment rod 412 is close to the side of the limiting groove 421 of the limiting plug 42. At this time, the adjustment rod 412 cannot deflect under the limiting action of the limiting groove 421, and can only move upward or downward relative to the lower shell 102; 02 clockwise rotation, the lower housing 102 moves upward relative to the adjusting rod 412 as an example, since the pen core 20 is tightly connected with the lower housing 102, the pen core 20 also moves upward relative to the adjusting rod 412, and the pen core 20 is also in clockwise rotation. The adjusting rod 412 will not rotate synchronously when the pen core 20 rotates clockwise. As the lower housing 102 continues to rotate, the second pen tip 32 will no longer rotate under the limiting effect of the adjusting protrusion 413 of the adjusting rod 412. Since the first pen tip 31 rotates with the lower housing 102, the pen core 20 moves upward relative to the adjusting rod 412. At the same time, the pen core 20 is also in clockwise rotation. 02 continues to rotate, so that the first pen tip 31 moves in a direction away from the second pen tip 32, thereby increasing the distance between the tips of the first pen tip 31 and the second pen tip 32; similarly, taking the counterclockwise rotation of the lower shell 102 and the downward movement of the lower shell 102 relative to the adjusting rod 412 as an example, since the pen core 20 is firmly fixed in the upper shell 101, the pen core 20 also moves downward relative to the adjusting rod 412, and at the same time, the pen core 20 is also in counterclockwise rotation when the lower shell 102 rotates synchronously, and the adjusting rod 412 is in the pen core 20 When rotating counterclockwise, it will not rotate synchronously. As the lower shell 102 continues to rotate, the second pen tip 32 will no longer rotate under the limiting action of the adjustment protrusion 413 of the adjustment rod 412. Since the first pen tip 31 continues to rotate with the lower shell 102, the first pen tip 31 moves in the direction close to the second pen tip 32, and the distance between the tips of the first pen tip 31 and the second pen tip 32 becomes smaller, thereby controlling the width of the handwriting of the pen tip assembly 30, thereby meeting the writing requirements corresponding to pen tips of different thicknesses.
[0054] When the utility model is used specifically, taking the structure of the integrated shell 10 as an example, the stopper 42 is placed in the opening of the lower end of the shell 10, which not only ensures the beauty of the product, but also ensures the limiting effect of the adjustment ring 41; in the initial state, the distance between the tips of the first nib 31 and the second nib 32 is the smallest. When the distance between the tips of the first nib 31 and the second nib 32 needs to be adjusted, the user pinches the stopper 42 with one hand and rotates the shell 10 clockwise with the other hand. Under the limiting effect of the limiting groove 421 of the stopper 42, the adjustment ring 41 and the adjustment rod 412 only move downward relative to the stopper 42 and no longer rotate; the adjustment protrusion 413 moves downward along the slide groove 301, due to The second nib 32 is limited by the adjustment protrusion 413, and the second pen core 20 no longer rotates relative to the limit plug 42, while the first nib 31 continues to rotate with the shell 10, so that the first nib 31 and the second nib 32 are separated from each other, thereby achieving the effect of increasing the tip distance between the second nib 32 and the first nib 31; similarly, when it is necessary to reduce the tip distance between the second nib 32 and the first nib 31, the user only needs to pinch the limit plug 42 with one hand and rotate the shell 10 in the opposite direction with the other hand to complete the operation of bringing the first nib 31 and the second nib 32 closer together, thereby controlling the width of the handwriting of the nib assembly 30, thereby meeting the writing requirements corresponding to nibs of different thicknesses.
[0055] In summary, the utility model provides a multi-purpose fountain pen which adjusts the distance between the tips of the first nib 31 and the second nib 32 of the nib assembly 30 by setting an adjustment component 40, thereby controlling the width of the handwriting of the nib assembly 30, thereby meeting the writing requirements corresponding to nibs of different thicknesses.
[0056] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
