Description

Technical Field

[0001] This utility model relates to the field of watercolor pen technology, specifically to a folding double-ended watercolor pen. Background Technology

[0002] Watercolor pens are a type of drawing tool, commonly used by children. The nibs are usually made of carbon fiber and are typically sold in boxes of 12, 24, or 36 colors. The nibs are generally round, making it difficult to mix two colors together. They are generally suitable for children's drawings and can also be used as markers.

[0003] Existing watercolor pens typically feature a single-ended design, with the tip often made of carbon fiber. This results in fixed colors that are difficult to mix, and their functionality is relatively limited. To improve ease of use, double-ended watercolor pens have gradually appeared on the market, using different colored tips at both ends of the same pen barrel to expand color selection. However, existing double-ended watercolor pen designs still have significant drawbacks:

[0004] Firstly, the stability of the folding structure is insufficient. Although some double-ended pens have folding functions, their complex structure can lead to jamming or wear of parts during folding, and may cause loosening or even breakage after long-term use.

[0005] Secondly, the sealing performance is poor. The existing pen cap is not well-fitted to the pen body, and the limiting structure relies on simple buckles, which makes it easy to loosen when vibrated or dropped, resulting in ink leakage due to capillary action and contaminating the carrying environment.

[0006] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0007] In view of the problems in the related technologies, this utility model proposes a folding double-ended watercolor pen to overcome the above-mentioned technical problems existing in the existing related technologies.

[0008] Therefore, the specific technical solution adopted by this utility model is as follows:

[0009] A folding double-ended watercolor pen includes a first pen body and a second pen body. An adjustment component is provided between the first pen body and the second pen body. A protective component is provided at one end of the first pen body and the second pen body. The adjustment component includes a rotating groove, which is symmetrically opened at one end of the first pen body. A rotating protrusion is provided on one side of the rotating groove. A movable plate is movably connected to the rotating protrusion. An adjustment groove is opened on the movable plate.

[0010] Furthermore, to better ensure the adjustment effect, the rotating protrusion is slidably connected inside the adjustment groove, and one end of the movable plate is fixedly set at one end of the second pen body.

[0011] Furthermore, in order to better ensure the limiting effect, a snap-fit ​​plate is symmetrically arranged on one side of the first pen body, and a plurality of first limiting protrusions are provided on the snap-fit ​​plate. A first limiting groove is opened on one side of the second pen body, and the snap-fit ​​plate and the first limiting protrusions are adapted to the first limiting groove.

[0012] Furthermore, in order to better ensure the protective effect, the protective component includes a pen cap, which is disposed at one end of the first pen body and the second pen body, and the pen cap is adapted to the first pen body and the second pen body. The outer walls of the first pen body, the second pen body, and the pen cap are respectively symmetrically provided with a second limiting groove and a third limiting groove.

[0013] Furthermore, in order to better ensure the limiting effect, the inner walls of the second limiting groove and the third limiting groove are provided with a storage groove, and a limiting spring is provided inside the storage groove. One end of the limiting spring is provided with a second limiting protrusion.

[0014] Furthermore, in order to better ensure the limiting effect, a limiting plate is fixedly provided on one side of the pen cap, and the limiting plate is adapted to the second limiting groove and the third limiting groove respectively. Grooves are provided on both sides of the limiting plate, and the second limiting protrusion is adapted to the groove.

[0015] Furthermore, to better ensure the sealing effect, the protective component also includes multiple sealing rings, which are fixedly disposed on the inner wall of the pen cap. The first pen body and the second pen body are provided with sealing grooves, and the sealing rings are adapted to the sealing grooves.

[0016] The beneficial effects of this utility model are as follows: By adjusting the coordination of the rotating groove, rotating protrusion and movable plate in the component, as well as the matching design of the snap-fit ​​plate and the first limiting groove, the flexible folding and precise positioning of the double pen body are realized, which effectively avoids the problems of easy jamming, wear or loosening of the existing folding structure, and significantly improves the structural stability and service life. By setting the protective component and using the cooperation of the sealing ring and sealing groove to form a multiple sealing barrier, it can effectively prevent ink leakage caused by capillary action or external vibration, ensuring safe carrying and avoiding environmental pollution.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1:

[0030] like Figures 1-8As shown, a folding double-ended watercolor pen according to an embodiment of the present utility model includes a first pen body 1 and a second pen body 2. The first pen body 1 and the second pen body 2 are conventional structures (not shown in detail), usually consisting of a pen barrel, a pen tip, and a pen core. An adjustment component 3 is provided between the first pen body 1 and the second pen body 2, and a protective component 4 is provided at one end of the first pen body 1 and the second pen body 2.

[0031] The adjustment component 3 includes a rotating groove 301, which is symmetrically opened at one end of the first pen body 1. A rotating protrusion 302 is provided on one side of the rotating groove 301. A movable plate 303 is movably connected to the rotating protrusion 302. An adjustment groove 5 is opened on the movable plate 303. The rotating protrusion 302 is slidably connected inside the adjustment groove 5. One end of the movable plate 303 is fixedly set at one end of the second pen body 2. A snap-fit ​​plate 304 is symmetrically arranged on one side of the first pen body 1. A plurality of first limiting protrusions 305 are provided on the snap-fit ​​plate 304. A first limiting groove 306 is opened on one side of the second pen body 2. The snap-fit ​​plate 304 and the first limiting protrusions 305 are all adapted to the first limiting groove 306.

[0032] Example 2:

[0033] like Figures 1-8 As shown, according to an embodiment of the present invention, a folding double-ended watercolor pen includes a protective component 4 comprising a pen cap 401. The pen cap 401 is disposed at one end of the first pen body 1 and the second pen body 2, and is adapted to the first pen body 1 and the second pen body 2. The outer walls of the first pen body 1, the second pen body 2, and the pen cap 401 are symmetrically provided with a second limiting groove 402 and a third limiting groove 403, respectively. The inner walls of the second limiting groove 402 and the third limiting groove 403 are provided with a storage groove 6. A limiting spring 404 is disposed inside the storage groove 6, and one end of the limiting spring 404 is provided with a second limiting spring. The pen cap 401 has a protrusion 405 and a limiting plate 406 fixedly installed on one side. The limiting plate 406 is adapted to the second limiting groove 402 and the third limiting groove 403 respectively. The limiting plate 406 has grooves 7 on both sides, and the second limiting protrusion 405 is adapted to the grooves 7. The protective component 4 also includes multiple sealing rings 407. The sealing rings 407 are made of solvent-resistant rubber material (such as fluororubber). The sealing rings 407 are fixedly installed on the inner wall of the pen cap 401. The first pen body 1 and the second pen body 2 have sealing grooves 408, and the sealing rings 407 are adapted to the sealing grooves 408.

[0034] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0035] In summary, with the help of the above-mentioned technical solution of this utility model, when it is necessary to unfold the first pen body 1 and the second pen body 2, the operator holds the first pen body 1 and the second pen body 2 and applies force in opposite directions. At this time, the movable plate 303 slides outward along the rotating protrusion 302 through the adjustment groove 5. The rotating protrusion 302 generates a rotational displacement in the rotating groove 301, that is, a ninety-degree rotational movement. The first limiting protrusion 305 of the locking plate 304 is locked inside the first limiting groove 306, thereby completing the folding effect. This can better ensure that the grip length conforms to ergonomics and provide a comfortable writing experience.

[0036] When the pen cap 401 is fastened, the sealing ring 407 is compressed and undergoes radial deformation, tightly filling all assembly gaps between the first pen body 1, the second pen body 2 and the pen cap 401, forming an annular sealing barrier, effectively preventing ink leakage due to capillary action or gravity. When the limiting plate 406 is inserted into the second limiting groove 402 on the first pen body 1 and the second pen body 2, the limiting spring 404 in the receiving groove 6 pushes the second limiting protrusion 405 into the groove 7, generating a bidirectional elastic locking force. The preload of the limiting spring 404 ensures that the pen cap 401 remains closed under sudden external forces such as vibration and drops, preventing the seal from failing due to the pen cap 401 loosening.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
