For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.
[0037] Please refer to Figures 1 to 6The finger pen provided by the embodiment of the application is a finger pen with a soft tube core and a pen head, comprising a core, a pen body 1 and a pen head 2; a finger hole for inserting a finger is arranged on one side of the pen body 1, and the pen head 2 is detachably sleeved on the side of the pen body 1 away from the finger hole; a cavity is formed between the pen head 2 and the pen body 1, and the core is located in the cavity and is installed and limited on the pen head 2; the core comprises a core tube 3, a corner two-way head 4 and a pen nib 5, the core tube 3 is a soft tube, the corner two-way head 4 connects the core tube 3 and the pen nib 5, and a through hole 21 is arranged on the pen head 2 for the pen nib 5 to pass out, and the through hole 21 coincides with the center line of the finger hole.
[0038] The pen body 1 and the pen head 2 in the embodiment are both hard materials, wherein the pen head 2 can have a bullet head shape, the pen head 2 has a cavity inside, and after the pen body 1 is sleeved into the pen head 2, the cavity is formed between the pen body 1 and the pen head 2, and the pen body 1 and the pen head 2 are detachably connected, for example, they can be connected by clamping or bolting.
[0039] The pen body 1 is provided with a finger hole, which is used for inserting a finger for use, and therefore the slot type of the finger hole can be various shapes such as a cylindrical shape, an elliptical cylindrical shape, a curved surface shape or a conical shape, as long as the finger hole can drive the finger pen to move after the finger is inserted and does not affect normal writing work. In the example, the finger hole is designed as a cylindrical shape with a curved surface structure at one end.
[0040] It should be noted that the finger hole can be arranged as one or more cavities suitable for one or more fingers, and in the example, only a finger hole suitable for one finger is shown.
[0041] In order to improve the control accuracy of the finger pen, the pen nib 5 and the finger hole are preferably designed on the same axis, at this time the finger pen is equivalent to an extension of the finger, and the touch feeling, control accuracy and control flexibility of the finger can be obviously improved. The center line of the finger hole is the central axis of the circular finger hole, the axis of the pen nib 5 coincides with the center line of the finger hole, the pen nib 5 and the finger tip are on the same center, and therefore when writing by pressing ink, the force direction can be completely coincident with the ink pressing point, which will improve the control of the ink pressing force, and thus it is beneficial to more accurately control the thickness and twist of each stroke when writing, which will help to make the font more beautiful and attractive.
[0042] Since the core tube 3 is spirally coiled, and the pen nib 5 is located on the center line of the core tube 3, if the two are directly connected together, and the core tube 3 is a soft tube, the soft tube is prone to excessive deformation due to being squeezed near the connection part, and then ink leakage or poor ink discharge may occur.
[0043] To this end, the application adopts a soft refill tube 3 and limits the refill tube 3 on the inner wall of the pen head 2 in a spiral winding manner, and the corner two-way joint 4 matched on the refill can realize the large-angle deflection connection between the refill tube 3 and the pen point 5 in a small space, which will help to reduce the bending amplitude value of the bending part of the refill tube 3. The design scheme can not only simplify the production and manufacturing process, but also reduce the production cost of the whole pen.
[0044] Since the refill tube 3 is spirally wound and positioned on the inner wall of the pen head 2, the refill is sleeved on the pen body 1 synchronously with the pen head 2 during assembly. When the design scheme is adopted, the whole installation process of the refill is relatively troublesome, but after the pen head 2 and the pen body 1 are folded, the spiral soft tube will be forced to tightly adhere to the inner wall of the pen head 2 due to the outward tension of the spiral soft tube, so that the overall stability of the positioned refill is good. At the same time, since the pen body 1 is not much affected by the friction force between the spiral soft tube and the pen head 2, the pen head 2 and the pen body 1 can be easily separated.
[0045] According to some embodiments of the application, the corner two-way joint 4 includes a first connecting column 41 connected with the refill tube 3 and a second connecting column 42 connected with the pen point 5, and the axis of the first connecting column 41 and the second connecting column 42 has a corner angle, and the corner two-way joint 4 has an oil channel therein, which penetrates the first connecting column 41 and the second connecting column 42.
[0046] The corner angle between the axis of the first connecting column 41 and the second connecting column 42 is 45°-90°, which can realize the large-angle deflection connection between the refill tube 3 and the pen point 5 in a limited space, which will help to reduce the bending amplitude value of the bending part of the refill tube 3, and further help to avoid the phenomenon of broken section or poor ink flow during writing.
[0047] According to some embodiments of the application, the corner two-way joint 4 includes a soft tube clasp 43 used to fix the refill tube 3 sleeved on the first connecting column 41. By arranging the soft tube clasp 43, the lap joint position of the refill tube 3 and the first connecting column 41 can be reinforced, so as to prevent the ink from overflowing from the lap joint part due to excessive extrusion deformation of the soft tube during the process of removing the air bubbles in the ink by high-speed centrifugal refill. At the same time, the soft tube clasp 43 can also limit the deformation of the soft tube segment located in the soft tube clasp 43 when the refill tube 3 is bent, which improves the bendable amplitude value of the bending part of the refill tube 3 under the premise of ensuring no ink leakage.
[0048] According to some embodiments of the present application, the corner two-way head 4 is provided with a first abutting punch 44, which is coaxially arranged opposite the second connecting column 42. Since the pen nib 5 is mounted on the second connecting column 42, by arranging the first abutting punch 44 in a straight line direction corresponding to the pen nib 5, the pen nib 5 can abut against the front end of the pen body 1, thereby assisting the positioning of the corner two-way head 4, and facilitating the insertion of the pen nib 5 into the through hole 21 of the pen head 2.
[0049] According to some embodiments of the present application, the corner two-way head 4 is further provided with a second abutting punch 45, which is arranged at an end opposite to the first connecting column 41, and is coaxially arranged between the second abutting punch 45 and the first connecting column 41. The main purpose of the second abutting punch 45 is to serve as a mechanical needle receiving surface, assisting in the abutment of the corner two-way head 4 and the hose clasp 43, as well as the corner two-way head 4 and the refill tube 3, and also assisting in the positioning of the corner two-way head 4 on the pen body 1.
[0050] According to some embodiments of the present application, the inner wall of the pen head 2 is provided with a guide groove 81 and a spiral groove 82, the spiral groove 82 is arranged around, the refill tube 3 is limited in the spiral groove 82, the first end of the spiral groove 82 is through the guide groove 81, and the corner two-way head 4 is limited in the guide groove 81. When installing the refill, the refill can be first introduced from the guide groove 81, the corner two-way head 4 and the hose clasp 43 are put into the guide groove 81, the pen nib 5 is inserted into the through hole 21 of the pen head 2, then the corner two-way head 4 and the hose clasp 43 are rotated 20°-45° around the pen nib axis, the corner two-way head 4 and the hose clasp 43 are turned into the first groove 83 and the second groove 84, and the relative positioning of the movement of the corner two-way head 4 and the hose clasp 43 in the direction of the finger hole axis is completed, then the refill tube 3 is wound into the spiral groove 82, and the entire refill is positioned on the inner wall of the pen head 2, as shown in detail in Figure 5
[0051] In this embodiment, the outward tension of the spiral refill tube 3 will force it to tightly fit in the spiral groove 82 on the inner wall of the pen head 2, so even if the refill tube 3 is short, it can still be used, and therefore the length of the refill tube 3 in this scheme is not too high, and the length of the refill tube 3 can be adjusted in a relatively large range, which means that different sizes of finger pens can be adapted to the same type of refill. Because different people have different sizes of fingers, the length of the finger hole on the finger pen is different, so for different sizes of the same type of finger pen, the length of the corresponding refill tube 3 is also different. This design scheme can improve the universality of different lengths of refill tube 3.
[0052] The pen core tube 3 and the corner two-way head 4 are actually in a mutual positioning relationship. The pen core tube 3 and the corner two-way head 4 are fixedly connected together through the hose clasp 43. When the pen core tube 3 is wound on the inner wall of the pen head 2, due to the influence of the spiral tension, only positioning any one end of the pen core tube 3 can completely position the pen core tube 3 on the inner wall of the pen head 2, so that when the pen core tube 3 is wound, the positioning of the pen core tube 3 is completed, and at the same time, the circumferential positioning of the corner two-way head 4 and the hose clasp 43 in the axial direction of the winding hole is completed. In addition to the movement positioning in the axial direction of the winding hole, the omnidirectional positioning of the corner two-way head 4 and the hose clasp 43 is completed, and thus the positioning of the entire pen core on the inner wall of the pen head 2 is completed.
[0053] In this embodiment, the pen tip 5 is fixed on the second connecting column 42 on the corner two-way head 4. When the entire pen core is positioned on the inner wall of the pen head 2, the through hole 21 on the pen head 2 actually mainly assists in the coaxial positioning of the winding hole and the pen tip 5. The through hole 21 not only needs to be used to pass through the pen tip 5, but also needs to assist in positioning the entire pen core on the axial centerline of the winding hole. When the pen core tube 3 is wound, the omnidirectional positioning of the corner two-way head 4 and the hose clasp 43 is also completed, and once it is wound, it is difficult to change. Therefore, once the pen core tube 3 is wound, the axial centerline of the pen tip 5 is determined. Once the pen core tube 3 is wound, it is easy to cause the pen tip 5 to deviate from the axial centerline of the winding hole. Therefore, when the design scheme is actually implemented, the through hole 21 on the pen head 2 must be designed to be slightly deep, and the hole diameter value of the through hole 21 cannot be too large, and is preferably matched with the outer diameter value of the pen tip 5. Even if there is a slight error during winding, the pen tip 5 can still be constrained by the through hole 21 on the pen head 2, so that the pen tip 5 is still on the axial centerline of the winding hole.
[0054] The lead-in groove 81 for leading in the pen core not only has a lead-in function, but also can reduce the overall weight. The first groove 83 is mainly used to limit the position of the hose clasp 43, the second groove 84 is mainly used to limit the position of the second end of the corner two-way head 4 opposite to the hose clasp 43 (i.e. the second butt head 45), and the third groove 85 is mainly used to give space to the corner two-way head 4 and plays an auxiliary positioning role.
[0055] According to some embodiments of the present application, the depth of the spiral groove 82 is less than the radius of the refill tube 3. When the refill is installed into the inner wall of the pen tip 2, due to the spiral tension of the refill tube 3 outward, the hose will be forced to adhere to the inner wall of the pen tip 2, and only a little groove depth can guide the spiral track of the hose, so the depth of the spiral groove 82 on the inner wall of the pen tip 2 can be set shallow, so the shell thickness of the pen tip 2 can be slightly thinner, which not only reduces the weight, but also expands the inner diameter of the pen tip 2, which will facilitate the entire operation process when the refill is installed.
[0056] According to some embodiments of the present application, the cross section of the spiral groove 82 can be any one of square, circular, U-shaped. Preferably, the spiral groove 82 with a circular cross section is adopted.
[0057] According to some embodiments of the present application, a pen cap 6 for protecting the pen nib 5 is further included, and the pen cap 6 and the pen tip 2 are detachably connected. When the finger pen is not used, the pen cap 6 can be covered on the pen tip 2, thereby protecting the pen nib 5, and when writing is needed, the pen cap 6 can be removed.
[0058] According to some embodiments of the present application, a pen clip can be further provided on the outer wall of the pen cap 6, thereby facilitating the clamping of the finger pen on a book or clothes. Meanwhile, a hanging hole can be provided on the pen clip, thereby facilitating the hanging of the finger pen by a hanging rope.
[0059] According to some embodiments of the present application, a gas guide hole is provided on the pen tip 2, and the gas guide hole is in communication with the cavity for accommodating the refill. Since the cavity enclosed between the pen tip 2 and the pen body 1 is relatively closed, in order to facilitate the ink discharge of the refill, the gas guide hole for communicating the outside and the cavity can be provided, so as to maintain the pressure balance in the cavity, thereby ensuring the stability of the ink discharge at the pen nib 5 during writing. The specific position of the gas guide hole is not limited here.
[0060] According to some embodiments of the present application, a flexible finger sleeve 7 is provided in the finger hole. Since the pen body 1 is generally made of hard material, discomfort may occur during long-term use, and in order to improve the comfort during writing, the flexible finger sleeve 7 is specially provided. The flexible finger sleeve 7 not only improves the comfort, but also can adapt to the size of the fingers of different people with different thicknesses of the flexible finger sleeve 7. At the same time, the flexible finger sleeve 7 can also strengthen the adhesion between the finger pen and the finger, thereby preventing the finger pen from falling off the finger.
[0061] According to some embodiments of the present application, a flexible sleeve 7 is provided with a stretchable opening on the side wall thereof. When the flexible sleeve 7 is put into or taken out of the finger hole, the stretchable opening can facilitate the air to be discharged or sucked, thereby facilitating the installation or disassembly of the flexible sleeve 7. Meanwhile, the stretchable opening can also become an air passage connecting the inside and outside of the finger hole, which can effectively prevent the air from being stagnant in the finger hole and improve the comfort during writing.
[0062] According to some embodiments of the present application, an annular protrusion 11 is arranged on the outer wall of the pen body 1 in a circumferential direction, and a connecting thread is arranged on the inner wall of the pen head 2, which is matched with the annular protrusion 11, thereby realizing the detachable connection between the pen body 1 and the pen head 2.
[0063] The above detailed description is further used to explain the purpose, technical scheme and beneficial effects of the present application. It should be understood that the above description is only a specific embodiment of the present application and is not used to limit the protection scope of the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application should be included in the protection scope of the present application.
