Description

Technical Field

[0001] The utility model relates to the field of stationery, in particular to a direct liquid drawing pen. Background Art

[0002] A direct liquid pen is a writing tool that uses water-based, oil-based or other liquid color pastes as ink. The pen is dipped in ink for writing, and the ink is evenly applied to the paper surface by the rolling of the ball bearing on the pen tip, thereby achieving writing. As an important drawing tool, the direct liquid drawing pen is deeply loved by users for its advantages such as smooth writing, bright colors and easy portability.

[0003] When adding ink to a direct liquid drawing pen, the user usually needs to open the cap at the end of the pen barrel and inject ink into the ink storage chamber inside the pen barrel.

[0004] Since the tail cap needs to be opened and closed repeatedly to add ink, the connection between the cap and the pen barrel is prone to wear after long-term use, causing the cap to loosen. During carrying or use, the loose cap is easy to fall off, causing ink leakage, which not only pollutes the environment, but also may damage the user's clothes or equipment. The tail cap of some direct liquid drawing pens is designed too tightly, and it takes a lot of effort to open or close the cap. Utility Model Content

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] Reference Figure 1-Figure 5 , a direct liquid drawing pen includes: a pen barrel 10, which provides a stable gripping basis to ensure stability during drawing; a groove 101, which is opened at one end of the pen barrel 10; an ink filling hole 102, which is opened at a side wall of the groove 101 and is used to store ink; a connecting part 30, which is arranged in the groove 101 and connected to the ink filling hole 102, and is used to control the opening and closing of the ink filling hole 102; a pen cover part 20, which is installed at the other end of the pen barrel 10 and is detachably connected to the pen barrel 10. When the pen cover part 20 is removed, it can interact with the connecting part 30 to control the connection state of the connecting part 30 in the ink filling hole 102 to realize the opening and closing of the ink filling hole 102. It is more labor-saving to use the pen cover part 20 to control the connecting part 30. The connecting part 30 is arranged in the groove 101 of the pen barrel 10 to prevent loosening and detachment due to accidental touch, thereby preventing ink from flowing out of the pen barrel 10.

[0043] Reference Figure 3-Figure 5 The pen barrel 10 includes: an end cap 103, which is installed at one end of the pen barrel 10; an inner cap 104, which is installed at one side of the end cap 103 and connected to the groove 101; the connecting part 30 includes: a rotating block 301, which is connected to the groove 101; a threaded head 302, which is installed at one side of the rotating block 301 and connected to the ink filling hole 102. The rotating block 301 allows the user to control the opening and closing of the ink filling hole 102 by rotating, which effectively prevents ink leakage. The threaded head 302 ensures the tightness of the connecting part 30. The tightness and reliability are improved, and ink leakage is further prevented; the docking groove 303 is opened on the other side of the rotating block 301; the pen cover part 20 includes: a connecting groove 201, opened at one end of the pen cover part 20; a connecting block 202, installed on the inner wall of the connecting groove 201; a docking block 203, installed on the connecting block 202, adapted to the docking groove 303, and the docking groove 303 provides an adapted space for the docking block 203 of the pen cover part 20, so that the pen cover part 20 can control the state of the connecting part 30 when it is removed.

[0044] Reference Figure 2 The diameter of the connecting groove 201 is larger than the diameter of the pen barrel 10 , and the pen cover 20 can be movably sleeved on one end of the pen barrel 10 .

[0045] Reference Figure 2 and Figure 5 The projection shape of the connecting block 202 is a hexagon, and the cross-sectional shape of the docking groove 303 is a hexagon.

[0046] Reference Figure 4 The inner wall of the ink filling hole 102 is formed with a thread groove, which is threadedly connected to the thread head 302.

[0047] Reference Figure 3 and Figure 4 The diameter of the connecting block 202 is smaller than the diameter of the groove 101 . When the pen cover portion 20 is sleeved on the pen barrel portion 10 , the connecting block 202 can be disposed in the groove 101 .

[0048] During use, the pen cover 20 is sleeved on one end of the pen barrel 10 to form a tight and detachable connection with the pen barrel 10. The rotating block 301 is located in the groove 101, and the threaded head 302 is tightly connected to the threaded groove on the inner wall of the ink filling hole 102. The ink filling hole 102 is in a closed state to prevent ink leakage. When drawing is needed, the user gently rotates and removes the pen cover 20. Since the diameter of the connecting groove 201 is larger than the diameter of the pen barrel 10, the pen cover 20 can be easily and movably sleeved on the pen barrel 10, which is convenient for removal. When adding ink, first open the end cover 103 and sleeve the pen cover 20 on On the pen barrel 10, the pen cap 20 is rotated. The pen cap 20 rotates on the pen barrel 10 and drives the rotating block 301 to rotate. The rotating block 301 drives the threaded head 302 to rotate, so that the threaded head 302 is separated from the threaded groove of the ink filling hole 102. The ink filling hole 102 is opened, and ink is added to the pen barrel 10 through the ink filling hole 102 until the ink reaches an appropriate storage amount. The rotating block 301 and the threaded head 302 are put into the groove 101 again, and the pen cap 20 is rotated in the opposite direction to make the threaded head 302 tightly connected with the threaded groove of the ink filling hole 102, and the ink filling hole 102 is closed to prevent ink leakage.

[0049] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0050] The opening and closing of the ink filling hole 102 is controlled by the interaction between the pen cap portion 20 and the connecting portion 30. The connecting portion 30 is arranged in the groove 101 of the pen shaft portion 10, which effectively prevents loosening due to external impact or accidental touch and ensures a tight connection between the pen shaft and the tail end cover 103.

[0051] The tight connection design between the rotating block 301 and the threaded head 302 further enhances the sealing performance of the ink filling hole 102, thereby preventing ink from leaking even in a bumpy or vibrating environment.

[0052] The user does not need to take the trouble to open or close the tail cover 103 , but can open and close the ink filling hole 102 by simply rotating the pen cover 20 , which makes the operation more convenient and improves the user experience.

[0053] The shapes of the connecting block 202 and the docking groove 303 are designed to be hexagonal, which increases the stability and firmness of the structure and makes the connection between the pen cover part 20 and the connecting part 30 more reliable.
