Description
Technical Field
[0001] This utility model relates to the field of writing instruments, and in particular to a capacitive pen cap and a capacitive pen. Background Technology
[0002] The advent of capacitive pens has greatly improved the efficiency of using tablets and mobile phones. However, due to their small size, smooth surface, and mostly cylindrical shape, capacitive pens are prone to slipping or rolling away during use. Therefore, using a pen sleeve to cover the capacitive pen can greatly improve the problems of frequent breakage and uncomfortable grip during writing. However, existing capacitive pen sleeves have the following problems: either they cannot be used to charge the pen directly, requiring the sleeve to be removed for charging, which is cumbersome and increases the likelihood of losing the sleeve and breaking the pen; or the pen sleeve is fixed to the tablet and only serves as a substitute for a charging dock, failing to provide protection during writing and causing discomfort during grip; or the structure is too complex.
[0003] Therefore, it is necessary to provide a capacitive pen sleeve and a capacitive pen to solve the above-mentioned technical problems. Utility Model Content

[0032] like Figure 1 , Figure 2 , Figure 3 As shown, a capacitive pen sleeve 100 includes a pen barrel 110, a pen hook 120, and a pen cap sleeve 130. The pen barrel 110 includes a pen barrel tube 111 and a decorative panel 112. The pen barrel tube 111 includes a thin pen barrel tube 1112 and a thick pen barrel tube 1113. The outer surfaces of the thin pen barrel tube 1112 and the thick pen barrel tube 1113 are provided with a pen sleeve magnetic attraction part 1115 with a planar structure on the same plane, which is used for surface contact to charge the capacitive pen body 200. The thick pen barrel tube 1113 is used to assemble the pen cap sleeve 130. The pen barrel tube through hole 1116 on the pen sleeve magnetic attraction part 1115 on the thick pen barrel tube 1113 is provided with a pen barrel through hole 1116 that matches the size of the decorative panel 112. The thick pen barrel tube 1113 and the decorative panel 112 are detachably connected by a snap-fit. The decorative panel 112 is used to beautify and improve the appearance of the capacitive pen sleeve 100. The magnetic pen sleeve portion 1115 of the thin pen tube 1112 is also provided with a touch through hole 1118 for convenient touch control of the switch of the capacitive pen body 200 (not shown in the figure); the pen hook 120 is detachably connected to the pen tube 110 for retracting the pen head 210 of the capacitive pen body 200 into the pen tube 110; the pen cap sleeve 130 is sleeved on the outer layer of the pen cap (the pen cap and the capacitive pen body are integrated, not shown in the figure) at the other end of the capacitive pen body 200 away from the pen head 210, and is snapped into the cavity of the pen tube 110, serving to press and extend the capacitive pen body 200 out of the pen tube 110.
[0033] Specifically, such as Figure 8 , Figure 10 As shown, the end of the thin pen tube 1112 away from the thick pen tube 1113 is provided with a pen tip fixing part 1111. The diameter of the pen tip fixing part 1111 gradually decreases at one end, which is used to fix the pen head 210.
[0034] By simplifying the structure of the pen holder 110, and providing a planar magnetic pen sleeve 1115 and a touch through-hole 1118 on the outer surface of the pen holder 110, the pen sleeve 100 can be placed over the pen body 200. This not only protects the pen body 200 from damage, but also allows for charging of the pen body 200 with the pen sleeve 100 in place, achieving a barrier-free magnetic attraction and stress-free charging. Furthermore, it allows for zero-contact control of the pen body 200's on / off function, making it convenient to use. In addition, the pen sleeve 100 has a simple structure and low manufacturing cost.
[0035] like Figure 3 , Figure 6 , Figure 7 As shown, a pen hook mounting block 1119 is provided at one end of the thick pen barrel 1113 away from the pen head 210. The pen hook mounting block 1119 includes a pen hook mounting block body 11192, and a pen hook limiting groove 11191 is axially provided on the inner wall of the pen hook mounting block 1119. A first pen barrel through hole 11194 and a second pen barrel through hole 11195, which are connected to the pen hook limiting groove 11191, are radially provided at one end of the pen barrel 110 away from the pen head 210. A pen hook mounting part 11193 is provided at one end of the pen hook mounting block body 11192 away from the second pen barrel through hole 11195. The pen cap sleeve 130 includes a pen cap sleeve body 131, and the outer part of the pen cap sleeve 130... A pen cap mounting and limiting part 132, adapted to the pen hook limiting groove 11191, is axially provided on the surface. The pen cap mounting and limiting part 132 has a convex structure, is limited within the pen hook limiting groove 11191, and is slidably connected to it. A pen cap protrusion 134 is provided at one end of the pen cap mounting and limiting part 132 near the pen head 210. Pen cap gap through holes 133 are provided on three sides around the pen cap protrusion 134 to improve the elasticity of the pen cap protrusion 134, thereby improving the snap-fit effect between the pen cap 130 and the pen holder 110, and extending the service life of the pen cap 130. The pen cap 130 is snap-fitted to the pen holder 110 through the pen cap protrusion 134. Specifically, the pen cap protrusion 134 is snap-fitted to the first through hole 11194 and the second through hole 11195 of the pen holder.
[0036] like Figure 2 , Figure 3 , Figure 7 As shown, the pen holder 110 and the pen cap 130 are both provided with a limit structure at the same end in the same direction to prevent the capacitive pen body 200 from extending too far out of the pen holder 110 and being damaged.
[0037] Specifically, the magnetic suction part 1115 of the pen cap has a pen tube limiting groove 1114 at the end away from the thin pen tube 1112; the pen cap 130 has a pen cap opening groove 135 and a pen cap pressing limiting part 137 arranged axially in sequence. In use, when the end of the pen cap 130 near the pen cap pressing limiting part 137 is pressed, when the end face of the pen cap pressing limiting part 137 contacts the bottom of the groove 1114, the pen cap protrusion 134 is just locked into the second through hole 11195 of the pen tube, and at this time the pen head 210 is just close to contact the inner wall of the pen tip fixing part 1111, thereby protecting the capacitive pen body 200.
[0038] like Figure 7 As shown, a pen cap sleeve 130 has a pen cap sleeve through hole 136 at the end away from the pen body head 210. The pen cap sleeve through hole 136 helps to avoid the problem of difficulty in disassembling the pen body 200 due to negative pressure generated in the cavity between the pen cap (which is considered as a single piece, not shown in the figure) and the pen cap sleeve 130 after assembly. This facilitates the disassembly of the capacitive pen body 200.
[0039] like Figure 4 , Figure 5 As shown, the pen hook 120 includes a first pen hook pressing plate 121, and a second pen hook pressing plate 126 integrally formed therewith is disposed in the middle of the first pen hook pressing plate 121. The second pen hook pressing plate 126 has pressing plate gap through holes 124 on three sides around its perimeter, thereby ensuring that the second pen hook pressing plate 126 is elastic and can press the pen cap protrusion 134. The pen hook 120 has a first pen hook protrusion 122 and an elastic second pen hook protrusion 123 on the side near the pen barrel 110. The second pen hook protrusion 123 is disposed below the end of the second pen hook pressing plate 126 near the first pen hook protrusion 122. The distance between 122 and the second protrusion 123 of the pen hook is equal to the distance between the first through hole 11194 and the second through hole 11195 of the pen holder. The first protrusion 122 and the second protrusion 123 of the pen hook are used to retract the capacitive pen body 200 and disassemble the capacitive pen body 200, respectively. A pen hook frame 125 is provided at the end of the first pressing plate 121 of the pen hook away from the first protrusion 122 of the pen hook. A pen hook mounting blind hole 125a is provided in the center of the pen hook frame 125. In use, the pen hook 120 and the pen holder 110 are assembled together by fitting the pen hook frame 125 onto the pen hook mounting part 11193.
[0040] like Figure 8 , Figure 9 , Figure 10As shown, a capacitive pen includes a pen sleeve 100 and a spring 300. The pen body 200 includes a pen body 220 and a pen head 210. A planar pen body magnetic attraction part 230 is axially provided on the outer surface of the pen body 220. The pen body 200 is assembled in the pen sleeve 100 according to the pen body magnetic attraction part 230 and the pen sleeve magnetic attraction part 1115. The pen body magnetic attraction part 230 not only has a magnetic attraction with the pen sleeve magnetic attraction part 1115, but also has a D-shaped structure at the lateral interface with the pen sleeve 100, which has the function of limiting and preventing the pen body 200 from moving left and right. The spring 300 is assembled in the cavity of the pen sleeve 100, with one end abutting and connected to the spring limiting part 1117 of the coarse pen tube 1113 near the inner wall of the thin pen tube 1112, and the other end abutting and connected to one end face of the pen cap sleeve 130.
[0041] During assembly, the pen body 200 is inserted into the pen sleeve 100 from the end of the pen barrel limiting groove 1114, then the spring 300 is inserted, and then the pen cap sleeve 130 is put on the outer layer of the pen cap (which is integrated and not shown in the figure) and pressed, so that the pen cap sleeve protrusion 134 is snapped into the first through hole 11194 of the pen barrel; the pen hook 120 is installed together with the pen sleeve 100; when in use, the pen cap sleeve 130 is pressed, so that the pen cap sleeve protrusion 134 is snapped into the second through hole 11195 of the pen barrel, so that the pen head 210 extends out of the pen tip fixing part 1111 for use. After use, press the end of the first pressing plate 121 of the pen hook, so that the first protrusion 122 of the pen hook presses the protrusion 134 of the pen cap. Under the action of the spring 300, the pen head 210 retracts into the pen tip fixing part 1111, and the protrusion 134 of the pen cap is locked in place. To remove the capacitive pen body 200, press the second pressing plate 126 of the pen hook, so that the second protrusion 123 of the pen hook presses the protrusion 134 of the pen cap. Under the action of the spring 300, the pen cap can pop out of the thick pen tube 1113, and the capacitive pen body 200 can be removed.
