Description

Technical Field

[0001] This utility model relates to the field of watercolor pen technology, specifically a watercolor pen with an anti-loss pen cap. Background Technology

[0002] A watercolor pen consists of three parts: the barrel, the nib, and the ink cartridge. The barrel makes it easy to hold, the nib affects the drawing effect, and the cartridge stores the ink. Watercolor pens offer a rich variety of colors, are easy to clean, and are mainly used for children's painting, artistic creation, and educational learning. Their diverse nib designs and good ink flow make the painting effects more vivid.

[0003] Utility model patent CN215705302U discloses a watercolor pen, including a pen shell, a pen tip, and a pen cap. The pen cap includes a housing threadedly connected to the pen shell and a pen groove for accommodating the pen tip. The housing has an ink cavity, and the ink cavity has a sealing cap fitted onto the outer wall of the groove. A pressure plate is provided at the bottom of the groove, and a connecting rod is provided on the inner bottom wall of the sealing cap. The connecting rod passes through the bottom wall of the pen groove and connects to the pressure plate. The pressure plate and the bottom wall of the groove are connected by a spring. The side wall of the pen groove has an opening to the ink cavity. The inner wall of the ink cavity has a sliding groove and a sealing sleeve that can slide up and down along the sliding groove to open or close the sliding groove. The outer wall of the sealing sleeve fits against the inner wall of the sealing cap. The bottom of the sealing plate has a magnetic block and is connected to the inner wall of the ink cavity by a spring. A fixing block is provided at the upper end of the pen shell corresponding to the sealing plate. The upper end of the fixing block has a magnet that cooperates with the magnetic block. The pen cap is closed while ink is being added, reducing ink evaporation, making operation convenient, and eliminating the burden of cleaning.

[0004] While the aforementioned watercolor pens can add ink and protect the nib, their caps are designed like traditional watercolor pens, being separate units. This structure makes the caps easy to lose, and when the cap is lost, the nib is easily damaged due to lack of protection. It also soils the storage structure of the watercolor pens, causing many inconveniences in using them. Therefore, to address the above problems, a watercolor pen with an anti-loss cap is proposed. Utility Model Content

[0005] The technical problem this utility model aims to solve is to provide a watercolor pen with an anti-loss cap. This watercolor pen features a sliding cap that is slidably connected to the front of the pen body, presenting an integrated design. This effectively prevents the cap from being lost. When in use, the sliding cap, when slid to its frontmost position, completely covers the pen tip for protection. Simultaneously, its internal self-sealing pen tip protection mechanism automatically closes to protect the pen tip. When the sliding cap is slid to its rearmost position, the pen tip is fully exposed for easy use. Furthermore, during the sliding process, the self-sealing pen tip protection mechanism automatically opens under pressure, allowing the pen tip to be exposed. This solves the technical problem in comparative technologies where the cap and pen body are separate designs that can be disassembled and operate independently, leading to the easy loss of the cap.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0007] A watercolor pen with an anti-loss cap includes a main body containing a refill and a nib. The main body is composed of a rear and a front barrel. A sliding cap is fitted onto the front barrel, and when slid to its frontmost position, it completely covers the nib; when slid to its rearmost position, it fully exposes the nib. The sliding cap contains a self-sealing nib protection mechanism. When the cap is slid to its frontmost position, the mechanism closes to protect the nib; when slid backward, it opens to expose the nib. This watercolor pen features a sliding cap that is integrated into the front barrel, effectively preventing cap loss. In use, the sliding cap fully covers the nib for protection when slid to its frontmost position, and exposes the nib when slid to its rearmost position for easy use.

[0008] In one possible implementation, the self-sealing pen tip protection mechanism includes six sealing petals arranged in a circumferential array. When closed, adjacent sealing petals fit together to form a hexagonal pyramid-shaped protective shield structure. This structure ensures that, without external force, the sealing petals can close together to form a protective shield, thus protecting the pen tip.

[0009] In one possible implementation, the closing flap is made of an elastic material and includes a connecting piece and a triangular piece. The connecting piece is fixedly connected to the inner wall of the sliding pen cap, and a bending indentation is formed at the junction of the connecting piece and the triangular piece. Based on the above structure, when the triangular piece is squeezed, it will bend and rotate around the bending indentation as an axis and elastically deform, thereby making the closing flap open as a whole, so that the sliding of the pen cap will not be obstructed. When the sliding pen cap is reset, due to the loss of external force, the triangular piece will return to its original position to protect the pen tip.

[0010] In one possible implementation, the self-sealing pen tip protection mechanism further includes an auxiliary reset spring, one end of which is fixedly connected to the inner wall of the sliding pen cap, and the other end is fixedly connected to the triangular piece. The auxiliary reset spring can further enhance the automatic reset capability of the triangular piece through its own elasticity, ensuring that the triangular pieces can close together when restored.

[0011] In one possible implementation, the sliding pen cap includes a pen cap sleeve with an iron connecting hoop fixedly installed on the inner wall of its rear end. A limiting ring corresponding to the connecting hoop is provided at the pen tip position of the front pen barrel. The above structure can limit the stroke of the sliding pen cap through the snap-fit ​​action between the connecting hoop and the limiting ring. When the sliding pen cap moves the closing flap, the connecting piece does not contact the limiting ring. This structure can prevent the limiting ring from colliding with the connecting piece, thus preventing the triangular piece from being squeezed and deformed.

[0012] In one possible implementation, the front end of the rear pen barrel is provided with a first mounting groove, in which a first magnetic ring is embedded for adsorbing and fixing the connecting clamp. When the sliding pen cap is opened and the watercolor pen is used normally, the first magnetic ring can fix the position of the sliding pen cap by adsorbing the connecting clamp, so that it cannot slide easily, thus facilitating use.

[0013] In one possible implementation, a second mounting groove is provided at the position of the front pen barrel close to the limiting ring, in which a second magnetic ring is embedded for adsorbing and fixing the connecting clamp. When the sliding pen cap is closed, the second magnetic ring can fix the position of the sliding pen cap by adsorbing the connecting clamp, so that it cannot slide easily, ensuring that the sliding pen cap can continuously protect the pen tip.

[0014] In one possible implementation, when the sliding cap moves the closing flap backward, the pen tip of the front pen barrel comes into contact with the triangular piece. This structure can prevent the pen tip from directly contacting the triangular piece and wearing out when the sliding cap is slid.

[0015] In summary, this utility model has the following beneficial technical effects:

[0016] This watercolor pen features a sliding cap that is integrated into the front barrel, effectively preventing the cap from being lost. When the sliding cap is slid to the front, it completely covers the pen tip for protection, while when it is slid to the back, the pen tip is fully exposed for easy use.

[0017] In addition, the sliding pen cap is equipped with a self-sealing pen tip protection mechanism. When the sliding pen cap is slid to the front, the self-sealing pen tip protection mechanism closes to form a hexagonal pyramid-shaped protective shield structure, thereby protecting the pen tip. When the sliding pen cap slides backward, the self-sealing pen tip protection mechanism is squeezed and automatically opens, allowing the pen tip to be exposed, ensuring a smooth and unobstructed use process.

[0025] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0026] like Figure 1 - Figure 2As shown, this embodiment provides a watercolor pen with an anti-loss cap, including a pen body containing a refill and a pen tip. The pen body is composed of a rear pen body 1 and a front pen body 2. A sliding pen cap 3 is slidably fitted onto the front pen body 2. When slid to its foremost position, it completely covers the pen tip; when slid to its rearmost position, it completely exposes the pen tip. The sliding pen cap 3 contains a self-sealing pen tip protection mechanism 4. When the sliding pen cap 3 is slid to its foremost position, the self-sealing pen tip protection mechanism 4... The protective mechanism 4 closes to protect the pen tip. When the sliding cap 3 slides backward, the self-sealing pen tip protection mechanism 4 is squeezed open, allowing the pen tip to be exposed. The watercolor pen has a sliding cap 3, which is slidably connected to the front pen barrel 2, presenting an integrated design that can effectively prevent the cap from being lost. When in use, when the sliding cap 3 slides to the front end, it can completely cover the pen tip for protection, while when the sliding cap 3 slides to the back end, the pen tip can be fully exposed for easy use.

[0027] like Figure 3 - Figure 4 As shown, the self-sealing pen tip protection mechanism 4 includes six sealing petals 41 arranged in a circumferential array. When closed, adjacent sealing petals 41 fit together to form a hexagonal pyramid-shaped protective shield structure. This structure ensures that, without external force, the sealing petals 41 can close together to form a protective shield, protecting the pen tip. The sealing petals 41 are made of elastic material and include a connecting piece 411 and a triangular piece 412. The connecting piece 411 is fixedly connected to the inner wall of the sliding pen cap 3. A bending indentation 413 is provided at the junction of the connecting piece 411 and the triangular piece 412. Based on the above structure, when the triangular piece 412 is squeezed, it will bend and rotate around the bending indentation 413 and deform elastically, thereby making the sealing petals 41 open as a whole, so that the sliding of the sliding pen cap 3 will not be obstructed. When the sliding pen cap 3 is reset, due to the loss of external force, the triangular piece 412 will return to its original position to protect the pen tip.

[0028] In addition, the self-sealing pen tip protection mechanism 4 also includes an auxiliary reset spring 42, one end of which is fixedly connected to the inner wall of the sliding pen cap 3, and the other end is fixedly connected to the triangular piece 412. The auxiliary reset spring 42 can further enhance the automatic reset capability of the triangular piece 412 through its own elasticity, ensuring that the triangular pieces 412 can close together when they are restored. Figure 3 As shown.

[0029] like Figure 2As shown, the sliding pen cap 3 includes a pen cap sleeve 31, with an iron connecting hoop 32 fixedly installed on the inner wall of its rear end. A limiting ring 21 corresponding to the connecting hoop 32 is provided at the pen tip position of the front pen barrel 2. The above structure can limit the stroke of the sliding pen cap 3 through the snap-fit ​​action between the connecting hoop 32 and the limiting ring 21. When the sliding pen cap 3 moves the closing flap 41, the connecting piece 411 does not contact the limiting ring 21. This structure can prevent the limiting ring 21 from colliding with the connecting piece 411, thus preventing the triangular piece 412 from being squeezed and deformed.

[0030] To achieve positional fixation of the sliding pen cap 3 in both states, a first mounting groove 11 is provided at the front end of the rear pen barrel 1, in which a first magnetic ring 12 is embedded. This magnetic ring is used to attract and fix the connecting clamp 32. When the sliding pen cap 3 is open for normal use of the watercolor pen, the first magnetic ring 12 can fix the position of the sliding pen cap 3 by attracting the connecting clamp 32, preventing it from sliding easily and thus facilitating use. A second mounting groove 22 is provided near the limiting ring 21 of the front pen barrel 2, in which a second magnetic ring 23 is embedded. This magnetic ring is used to attract and fix the connecting clamp 32. When the sliding pen cap 3 is closed, the second magnetic ring 23 can fix the position of the sliding pen cap 3 by attracting the connecting clamp 32, preventing it from sliding easily and ensuring that the sliding pen cap 3 can continuously protect the pen tip. Figure 5 As shown.

[0031] To better protect the pen tip, when the sliding cap 3 moves the closing flap 41 backward, the pen tip of the front pen barrel 2 comes into contact with the triangular piece 412. This structure prevents the pen tip from directly contacting the triangular piece 412 and causing wear when the sliding cap 3 is slidable. Figure 2 As shown.

[0032] The working principle and usage process of this utility model:

[0033] This watercolor pen features a sliding cap 3, which is slidably connected to the front barrel 2, creating a seamless design that effectively prevents the cap from being lost. When the sliding cap 3 is slid to its foremost position, it completely covers the pen tip for protection. When slid to its rearmost position, the pen tip is fully exposed for easy use. Furthermore, the sliding cap 3 contains a self-sealing pen tip protection mechanism 4. When the cap is slid to its foremost position, the mechanism closes to form a hexagonal pyramid-shaped protective shield, further protecting the pen tip. When the cap slides backward, the mechanism automatically opens under pressure, exposing the pen tip and ensuring a smooth and unobstructed use.

[0034] The self-sealing pen tip protection mechanism 4 includes six sealing petals 41 arranged in a circumferential array. When closed, adjacent sealing petals 41 fit together to form a hexagonal pyramid-shaped protective shield structure. This structure ensures that, without external force, the sealing petals 41 can close together to form a protective shield, thus protecting the pen tip.

[0035] The closing flap 41 is made of elastic material and includes a connecting piece 411 and a triangular piece 412. The connecting piece 411 is fixedly connected to the inner wall of the sliding pen cap 3. A bending indentation 413 is provided at the junction of the connecting piece 411 and the triangular piece 412. Based on the above structure, when the triangular piece 412 is squeezed, it will bend and rotate around the bending indentation 413 as the axis and deform elastically, so that the closing flap 41 is in an open state, so that the sliding of the sliding pen cap 3 will not be obstructed. When the sliding pen cap 3 is reset, the triangular piece 412 will return to its original position to protect the pen tip due to the loss of external force.

[0036] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
