Description
Technical Field
[0001] This utility model relates to the field of capacitive pens, and more specifically, to an adjustable capacitive pen. Background Technology
[0002] A capacitive stylus is a pen made of conductive materials that possesses conductive properties, used to interact with capacitive touchscreens for human-computer interaction. It's an auxiliary device that uses conductive materials to mimic the human body (usually a finger) for human-computer interaction. Existing capacitive styluses primarily use hard or soft tips. With a hard tip, the width of the line written is determined by the width of the tip itself and does not change. In some situations, such as drawing, when larger lines are needed, the common method is to increase the line width by drawing back and forth, which is usually tedious. While a soft tip can increase the contact area with the touchscreen and thus increase the line width by pressing, it's not easy to control the pressure when drawing with a soft tip, making it difficult to draw lines of consistent width.

[0004] The pen tube comprises a pen body and a baffle; the outer circumferential surface of the baffle is fixedly connected to a portion of the inner circumferential surface of the pen body; a connecting cavity is formed between one end face of the baffle and one end face of the pen body; a first threaded groove is provided on the inner circumferential surface of the pen body at the connecting cavity; the pen tip has a blind hole-like interior; the pen tip includes a connecting portion, a transition portion, and a contact portion; the contact portion is made of a soft material, and the transition portion is conical; its large-diameter end is fixedly connected to one end face of the connecting portion, and its small-diameter end is fixedly connected to the contact portion; a second threaded groove is provided on the outer circumferential surface of the connecting portion; the first threaded groove can be threadedly connected to the second threaded groove; one end of the push rod is detachably fixedly connected to the baffle, and the other end can abut against the inner surface of the contact portion.

[0022] This embodiment discloses an adjustable capacitive pen, such as Figure 1 , Figure 2 , Figure 3 As shown, it may include:
[0023] The pen tube 10, pen tip 20, and push rod 30 are provided. The pen tube 10 includes a tube body and a baffle 12. The outer peripheral surface of the baffle 12 is fixedly connected to a portion of the inner peripheral surface of the tube body. A connecting cavity 13 is formed between one end face of the baffle 12 and one end face of the tube body. A first threaded groove is provided on the inner peripheral surface of the tube body located at the connecting cavity 13. The pen tip 20 has a blind hole inside. The pen tip 20 includes a connecting part 21, a transition part 22, and a contact part 23. The contact part 23 is made of a soft material. The transition part 22 is conical. Its large-diameter end is fixedly connected to one end face of the connecting part 21, and its small-diameter end is fixedly connected to the contact part 23. A second threaded groove is provided on the outer peripheral surface of the connecting part 21. The first threaded groove can be threadedly connected to the second threaded groove. One end of the push rod 30 is detachably fixedly connected to the baffle 12, and the other end can abut against the inner surface of the contact part 23.
[0024] In this embodiment, the touch part 23 is made of a soft material. When it is necessary to adjust the width of the drawn line, simply twist the pen tube 10 or the pen tip 20 to change the pressure of the top rod 30 on the touch part 23, thereby changing the volume of the touch part 23 and increasing or decreasing the contact area between the touch part 23 and the touch screen. This allows lines of different sizes to be drawn, thus overcoming the problem that capacitive pens have difficulty drawing lines of the required width as needed.
[0025] In some embodiments, such as Figure 2 , Figure 3 As shown, the contact portion 23 is spherical; the top rod 30 includes a rod body portion 31 and a top contact portion 32; the diameter of the top contact portion 32 is larger than the diameter of the rod body portion; one end of the rod body portion 31 is detachably fixedly connected to the baffle 12, and the other end is fixedly connected to a portion of the outer surface of the top contact portion 32; another portion of the outer surface of the top contact portion 32 can abut against the inner surface of the contact portion 23.
[0026] In this embodiment, by setting the touch part 23 to be spherical and allowing a portion of the outer surface of the top contact part 32 to abut against the inner surface of the touch part 23, the distance between the two end faces can be changed by twisting the pen barrel or pen tip 20, thereby changing the pressure of the abutment part on the touch part 23, thus changing the deformation of the touch part 23 and the area of its outer surface, so that the touch part 23 can draw lines of different sizes on the touch screen.
[0027] In some embodiments, the soft material is conductive rubber.
[0028] In this embodiment, the soft material is preferably conductive rubber. However, those skilled in the art will know that, in some cases, any soft conductive material that can meet the application scenario of this utility model can be used to make the touch part 23 described in this utility model.
[0029] In some embodiments, such as Figure 2 , Figure 3 , Figure 4 As shown, a buckle 14 is fixedly connected to the end face of the baffle 12 near the pen tip 20; the buckle 14 is provided with a limiting groove 15 along its axial direction; the end of the rod part 31 away from the top contact part 32 can be inserted into the limiting groove 15; a sliding groove 16 and a locking groove 17 are provided on a portion of the peripheral wall of the buckle 14; the sliding groove 16 extends from the end face of the buckle 14 away from the baffle 12 along the axis of the buckle 14 toward the other end face of the buckle 14; the locking groove 17 passes through the central axis of the buckle 14 along the radial direction of a portion of the peripheral wall of the buckle 14. A portion of the peripheral wall of the buckle 14; the slot 17 is spaced apart from the end face of the buckle 14 away from the baffle 12; the slot 17 is connected to the slide groove 16; an elastic element 40 is provided in the limiting groove 15; the top rod 30 also includes a locking part 33; the locking part 33 is fixedly connected to a portion of the outer peripheral surface of the rod body 31; when the rod body 31 is inserted into the limiting groove 15, the rod body 31 can compress the elastic element 40, and the locking part 33 can slide in the slide groove 16, and the top rod 30 can be twisted to lock the locking part 33 into the slot 17.
[0030] In this embodiment, by setting a buckle 14 and providing an elastic element 40 inside the buckle 14, the elastic element 40 can apply a certain elastic force to the rod body, thereby enabling the top part 32 to be compressed by the contact part 23 when the pen tube 10 or pen tip 20 is twisted, so that the top part 32 will not break the contact part 23 while ensuring that the outer peripheral area of the contact part 23 is deformed by the top part 32.
[0031] In some embodiments, such as Figure 2 , Figure 3 As shown, the pen tip 20 also includes a limiting block 24; the limiting block 24 is provided with a limiting hole 25; the limiting hole 25 passes through both ends of the limiting block 24 along the central axis of the limiting block 24; the outer peripheral surface of the limiting block 24 is fixedly connected to a portion of the inner peripheral surface of the connecting part 21 or a portion of the inner peripheral surface of the transition part 22; the diameter of the limiting hole 25 is larger than the outer diameter of the top connecting part 32.
[0032] In this embodiment, by setting the limiting block 24 and the limiting hole 25, the limiting hole 25 can make the rod part move back and forth in its axial direction as much as possible, so as to ensure that the top part 32 and the inner surface of the contact part 23 have good contact.
[0033] In some embodiments, such as Figure 1 , Figure 3As shown, a plurality of anti-slip protrusions 26 are provided on a portion of the outer peripheral surface of the transition portion 22.
[0034] In this embodiment, by providing multiple anti-slip protrusions 26, the anti-slip protrusions 26 can help to twist the pen tube 10 and prevent slippage when twisting the pen tube 10.
[0035] In some embodiments, the anti-slip protrusions 26 are uniformly distributed along a portion of the outer peripheral surface of the transition portion 22.
[0036] In this embodiment, by uniformly setting the anti-slip protrusions 26, it is more conducive to increasing the friction between the hand and the pen tube 10 when twisting the pen tube 10.
[0037] In some embodiments, the anti-slip protrusion 26 is disposed on a portion of the outer peripheral surface of the transition portion 22 near the connecting portion 21.
[0038] In some embodiments, such as Figure 2 , Figure 3 As shown, the outer surface of the top joint 32 is spherical; the central axis of the rod body 31 passes through the center of the top joint 32.
[0039] In this embodiment, by setting the top contact portion 32 as a surface, the contact portion 23 can be expanded or reduced uniformly in its radial direction as much as possible, so that each part of the outer surface of the contact portion 23 can draw a line of the required width, thereby increasing the efficiency of drawing lines.
[0040] In the above embodiments, the pen tube 10, pen tip 20, and top rod 30 are all materials that are known to those skilled in the art and can be used in this utility model to enable the capacitive pen to work normally. Furthermore, the connection methods of each part are all connection methods that are known to those skilled in the art and can enable the capacitive pen to work normally, and will not be described in detail here.
[0041] The working principle of this utility model is as follows:
[0042] When it is necessary to draw lines of the required width, by twisting the pen tube 10 or the pen tip 20, the top contact part 32 of the top rod 30 moves away from or closer to the touch part 23, and the surface area of the outer peripheral surface of the touch part 23 changes, thereby changing the contact area between the touch part 23 and the touch screen, so as to draw lines of different widths. Furthermore, since the top contact part 32 is made of a hard material, it can also ensure the hardness of the touch part 23 when drawing with the capacitive pen, ensuring that the width of the drawn lines is always within a suitable range.
[0043] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the spirit and scope of this disclosure.
