Description

Technical Field

[0001] This utility model relates to the field of marker technology, and more specifically to a marker with switchable multi-color nibs. Background Technology

[0002] A marker is a pen that can write marks or markings on one or more materials such as paper, wood, metal, plastic, and enamel. Current markers are limited to a single color, which is inconvenient for daily use as it requires carrying different colored markers to mark different locations.

[0003] A multi-color marker with publication number CN220332323U in the prior art allows for switching between different colors by completely detaching the second pen tip from the inside of the protective cover and rotating the pen body to interchange the positions of the first and second pen tips. However, this utility model has the following problems: color switching is limited, only supporting two-color switching, which cannot meet the needs of multiple scenarios, and the marking method is limited to a single straight line. Therefore, this utility model proposes a marker with switchable multi-color pen tips. Utility Model Content

[0004] The purpose of this invention is to provide a marker with switchable multi-color tips, which can switch between multiple colors and has a variable marking method.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A marker pen with interchangeable multi-color tips includes a pen shell with two tips at its two ends, each with a lead outlet. A fixing plate is fixedly located in the center of the pen shell, and two through holes are symmetrically arranged on the fixing plate. A lead assembly passes through the through holes. The lead assembly includes an outer shell with a partition plate in the center, an inner core inserted into both ends of the outer shell, lead tips at both ends of the inner core, and end caps threaded to both ends of the outer shell. The lead assembly can be adjusted up and down by a transmission structure. The transmission structure includes an adjusting ring rotatably connected to the outside of the pen shell, an external gear located in the outer ring groove of the pen shell and fixedly connected to the inner side of the adjusting ring, and an internal gear rotatably connected to the fixing plate. The internal gear passes through a through groove and meshes with the external gear. The center of the internal gear is threadedly connected to the outer shell. A slider is provided at the lower end of the outer shell and slides in cooperation with a groove on the pen shell.

[0007] By adopting the above technical solution, this utility model has the following advantages:

[0008] The design of this invention, with its two lead outlets, two lead assemblies, and a transmission structure, allows the two lead assemblies to extend independently or synchronously from different outlets, enabling color switching or changes in marking methods. The transmission structure allows the rotation of an adjusting ring to drive the external gear to mesh with the internal gear, converting rotational motion into linear movement of the outer shell, thereby achieving the desired color switching.

[0009] Furthermore, the internal gear is engaged with the T-shaped ring plate on the fixed plate through the T-shaped ring groove, and the T-shaped ring plates have different heights, so that the internal gears are staggered.

[0010] By adopting the above technical solution, this utility model has the following advantages:

[0011] The T-shaped ring groove and T-shaped ring plate of this invention allow the internal gear to be confined to a fixed position while rotating freely.

[0012] Furthermore, the adjusting ring is rotatably connected to the L-shaped annular groove on the outside of the pen shell via an L-shaped annular plate.

[0013] By adopting the above technical solution, this utility model has the following advantages:

[0014] The L-shaped annular plate and L-shaped annular groove of this utility model ensure that the adjusting ring can only rotate along the pen shell, preventing it from shifting or falling off.

[0015] Furthermore, the pen casing is fitted with detachable pen caps at both ends.

[0016] By adopting the above technical solution, this utility model has the following advantages:

[0017] The pen cap of this invention serves to protect the pen tip.

[0018] Furthermore, the pen tip is fixed to the pen casing by a threaded connection.

[0019] By adopting the above technical solution, this utility model has the following advantages:

[0020] The threaded connection of the pen tip in this invention allows the pen refill assembly to be moved out of the pen casing for maintenance and replacement when the pen tip is unscrewed.

[0021] Furthermore, each of the inner cores is fixedly provided with a retaining ring on one side, and the retaining ring abuts against the inner side of the corresponding end cap.

[0022] By adopting the above technical solution, this utility model has the following advantages:

[0023] The retaining ring of this invention, when used in conjunction with the partition plate, can fix the inner core and effectively prevent the inner core from shaking. Attached Figure Description

[0030] like Figures 1 to 4 As shown in this specific embodiment, a marker pen with switchable multi-color tips includes a pen shell 1, with a pen tip 11 and a pen tip 9 at its two ends, and a lead outlet 101 at each corresponding position. A fixing plate 7 is fixedly provided in the center of the pen shell 1, and two through holes 701 are symmetrically provided on the fixing plate 7. The lead assembly passes through the through holes 701. The lead assembly includes a shell 3 with a partition plate 302 in the center, an inner core 4 inserted into both ends of the shell 3, a lead tip 402 at both ends of the inner core 4, and an end cap 301 threadedly connected to both ends of the shell 3. The lead assembly can be adjusted up and down through a transmission structure. The transmission structure includes an adjusting ring 5 rotatably connected to the outside of the pen shell 1, an external gear 14 fixedly connected to the inside of the adjusting ring 5 in the outer ring groove 6 of the pen shell 1, and an internal gear 8 rotatably connected to the fixing plate 7. The internal gear 8 passes through the through groove 601 and meshes with the external gear 14. The center of the internal gear 8 is threadedly connected to the shell 3. A slider 201 is provided at the lower end of the shell 3 and slides in cooperation with the sliding groove 2 provided on the pen shell 1.

[0031] Through the above configuration, the two lead outlets 101 at both ends, the two lead assemblies, and the transmission structure of this utility model enable the two lead assemblies to extend independently or synchronously from different lead outlets 101, thereby achieving color switching or changing the marking method. The transmission structure of this utility model allows the external gear 14 to mesh with the internal gear 8 by rotating the adjusting ring 5, converting the rotational motion into linear movement of the outer shell 3, thereby achieving the switching of the desired color.

[0032] like Figures 2 to 4 As shown, the internal gear 8 is engaged with the T-shaped ring plate 12 on the fixing plate 7 through the T-shaped ring groove 801, and the T-shaped ring plates 12 have different heights, so that the internal gears 8 are staggered; the adjusting ring 5 is rotatably connected to the L-shaped ring groove 13 on the outside of the pen shell 1 through the L-shaped ring plate 501; the two ends of the pen shell 1 are fitted with detachable pen caps 10; the pen tip 11 is fixed to the pen shell 1 by threaded connection; the inner core 4 is fixedly provided with retaining rings 401 on one side, and the retaining rings 401 abut against the inner side of the corresponding end cap 301.

[0033] Through the above settings, the T-shaped annular groove 801 and the T-shaped annular plate 12 of this utility model allow the internal gear 8 to be restricted to a fixed position and rotate freely; the L-shaped annular plate 501 and the L-shaped annular groove 13 of this utility model allow the adjusting ring 5 to rotate only along the pen shell 1, preventing it from shifting or falling off; the pen cap 10 of this utility model protects the pen tip 402; the threaded connection of the pen tip 11 of this utility model allows the pen tip assembly to be moved out of the pen shell 1 for maintenance and replacement when the pen tip 11 is unscrewed; the retaining ring 401 of this utility model, in conjunction with the partition plate 302, can fix the inner core 4, effectively preventing the inner core 4 from shaking.

[0034] Working principle: During manufacturing, color markings and rotation direction markings for different colors can be set on the adjusting ring 5. When in use, select the desired color according to the requirements, rotate the corresponding adjusting ring 5, drive the external gear 14 to rotate, thereby driving the internal gear 8 to rotate. The internal gear 8 drives the outer shell 3 to move along the slide groove 2 through the threaded connection. When the slider 201 abuts against the slide groove 2, the target pen tip 402 will extend from the corresponding tip outlet 101, and the corresponding color can be used for writing. When the two adjusting rings 5 ​​are rotated synchronously in the same direction, both outer shells 3 move at the same time, and the pen tips 402 on both sides of the same end move and extend at the same time, thus achieving double-line marking. By unscrewing the corresponding end cap 301, the inner core 4 can be replaced. By unscrewing the pen tip 11, the adjusting ring 5 can be rotated to completely remove the outer shell 3 from the pen shell 1 to replace it after damage.
