The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0031] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0032] like Figure 1-4 As shown, a marker pen convenient for ink filling comprises a pen holder 1, a cotton core 2 and a pen tip 3 detachably connected to one end of the pen holder 1, wherein the cotton core 2 is arranged in the pen holder 1, and a pen tip 4 is arranged at one end of the pen tip 3 away from the pen holder 1, and the cotton core 2 is connected to the pen tip 4;

[0033] One or two guide grooves 11 are provided at the connection between the inner side of the pen shaft 1 and the pen tip 3, and a first button hole 12 is provided at one end of the guide groove 11 away from the pen tip 3;

[0034] An extension section 31 is provided at one end of the pen tip 3 located in the pen barrel 1, and a pen tip button 32 matching with the first button hole 12 is provided on the extension section 31, and the pen tip button 32 is slidably connected with the guide groove 11;

[0035] The cotton core 2 and the extension section 31 are provided with ink injection ports (not shown in the figure) at positions corresponding to each other.

[0036] In this embodiment, when the nib 3 is connected to the pen barrel 1 , the nib button 32 is connected to the first button hole 12 . When the nib 3 is pulled out of the pen barrel 1 , the nib button 32 is located at the end of the guide groove 11 away from the first button hole 12 .

[0037] In this embodiment, the extending section 31 is provided so that the ink filling port of the cotton core 2 can extend out of the pen holder 1 after the pen tip 3 is pulled out.

[0038] like Figure 2 As shown, when the cotton core 2 needs to be filled with ink, an external force presses the first button hole 12 to disengage the nib button 32 from the first button hole 12. At the same time, the external force pulls out the nib 3 in the direction away from the pen barrel 1. During the process of pulling out the nib 3, the nib button 32 moves along the guide groove 11 in the direction away from the first button hole 12. When the nib button 32 is located at the end of the guide groove 11, the nib 3 is located as a whole on the outside of the pen barrel 1, and the ink filling port of the cotton core 2 is exposed to the outside of the pen barrel 1. Then, ink is filled into the cotton core 2 through the ink filling port. After completion, the nib 3 can be installed in the above manner.

[0039] Compared with the ink filling method of the prior art, the above structure adopts a structural design in which the pen tip button 32 cooperates with the button hole and the guide groove 11 to limit the pulling-out distance of the pen tip 3 and prevent the cotton core 2 from being pulled out as a whole and causing ink to flow out; in addition, after the pen tip 3 is pulled out, it is connected to the pen body 1 through the extension section 31, and during the ink filling process, there is no need to additionally take and place the pen tip 3 and worry about ink flowing out, making ink filling more convenient.

[0040] Further, such as Figure 1 , 2 As shown in FIG. 3 , the end of the guide groove 11 close to the pen tip 3 is provided with a second button hole 13 that cooperates with the pen tip button 32 .

[0041] In this embodiment, when the nib 3 is pulled out of the pen barrel 1, the nib button 32 is connected to the second button hole 13; after the nib 3 is pulled out, the nib button 32 is inserted into the second button hole 13 to fix the pulled out nib 3, thereby preventing the nib 3 from sliding relative to the pen barrel 1 during the ink filling process, thereby affecting the ink filling.

[0042] Further, such as Figure 1 , 2As shown in 3, it also includes a pen cap 5, which is detachably mounted on the pen mouth 3. A clamping assembly 6 of the pen mouth 3 is arranged on the pen cap 5. The clamping assembly 6 of the pen mouth 3 is used for clamping the pen mouth 3 when the pen cap 5 is pulled out, and the pen shaft 1 is pulled out together.

[0043] In this embodiment, when filling ink, the nib button 32 is pressed while pressing the clamping assembly 6, so that the nib 3 can be pulled out of the pen barrel 1 together with the pen cap 5, making it more convenient and labor-saving to pull out the nib 3.

[0044] Further, such as Figure 1 , 2 As shown in Figure 3, the clamping assembly 6 includes a pen cap button 61 arranged on the pen cap 5, one end of the pen cap button 61 is connected to the pen cap 5, and the other end is a free end. A card block 63 is arranged on the inner side of the free end, and a card slot 62 is arranged on the outer side of the pen mouth 3, and the card slot 62 and the card block 63 are arranged correspondingly.

[0045] In this embodiment, by pressing the free end of the cap button 61 to make the block 63 snap into the slot 62, and then pulling out the cap 5 with external force, the nib 3 can be pulled out of the pen body 1 together, which is convenient and labor-saving to operate.

[0046] Further, such as Figure 3 As shown, the slot 62 is a 360-degree annular groove with a rectangular or round-bottomed rectangular cross section.

[0047] In this embodiment, the card slot 62 adopts a 360-degree annular groove design, which increases the contact area with the card block 63, so that the position where the card block 63 is inserted into the card slot 62 is not affected by the rotation of the pen cap 5, and is more convenient to use.

[0048] Further, such as Figure 1 , 2 As shown in , 3 , the pen cap 5 completely covers the pen tip 4 arranged on the pen mouth 3 .

[0049] Furthermore, the first button hole 12 is a sealed button hole.

[0050] Furthermore, the second button hole 13 is a sealed button hole.

[0051] In this embodiment, the key hole is designed with a sealing structure to prevent the ink in the cotton core 2 from drying up.

[0052] Furthermore, the nib 3 and the pen barrel 1 are interference fit.

[0053] Furthermore, the pen tip 4 is a sintered pen tip.

[0054] In this embodiment, the sintered pen tip has a long service life and meets the requirements of a refillable marker pen.

[0055] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the scope of protection of the claims of the utility model patent.
