Description

Technical Field

[0001] This utility model relates to the field of stylus technology, and in particular to a magnetic stylus. Background Technology

[0002] A magnetic stylus is a pen-shaped device that combines magnetic and touch technologies, primarily used for precise operation and writing on touchscreens. A magnetic stylus typically consists of a sleeve, an electronic control component, a pen tip, and an internal magnet. The sleeve has an internal cavity for fixing the electronic control component, which includes a main control board and a battery electrically connected to the main control board. The pen tip is located at the front end of the sleeve and is used to contact the touchscreen. Most models have a charging dock protective cover that rotates to the rear end.

[0003] To maintain a clean appearance, current magnetic styluses generally do not have caps, and the caps are easily lost if not stored properly. Furthermore, magnetic styluses are prone to falling off when attached to a laptop, causing the pen tip to fall off and become damaged. Therefore, we propose a new type of magnetic stylus. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies and improve the structure of existing pen tips and caps, ensuring a simple appearance while preventing the caps from being lost when removed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A magnetic stylus includes a stylus body, which is composed of a pen tip and a pen barrel. The connection between the pen tip and the pen barrel is a columnar design and has an external thread. The pen barrel has a telescopic groove on the periphery of the columnar part facing the pen tip, and a connecting sleeve is slidably connected in the telescopic groove.

[0007] The outer thread of the external thread is connected to a pen cap, and the end face of the pen cap away from the connection end is provided with a metal snap-fit ​​block.

[0008] The pen barrel is threadedly connected to a charging protection cover at the end away from the pen tip, and the charging protection cover has a snap-fit ​​groove on the end face away from the connection end.

[0009] Furthermore, the cross-section of the pen tip and the connecting sleeve is V-shaped.

[0010] Furthermore, a spring is provided on the inner side of the connecting sleeve, and the two ends of the spring are respectively fixed to the connecting sleeve and the end of the telescopic groove away from the groove opening.

[0011] Furthermore, the depth of the telescopic groove is greater than the length of the connecting sleeve, so that the connecting sleeve can be completely housed within the telescopic groove by spring contraction.

[0012] Furthermore, the inner groove of the pen cap is convex in shape, and a protective pad for contacting the pen tip is fixed on the inner end face.

[0013] Furthermore, the slot and the metal locking block are compatible.

[0014] Furthermore, the slot is equipped with a magnetic block, which attracts the metal card block.

[0015] Furthermore, the length of the pen cap is greater than the length of the pen tip.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention features a telescopic groove on the periphery of the columnar part of the pen barrel facing the pen tip, and a connecting sleeve that slides within the telescopic groove. When the pen cap is installed, the connecting sleeve retracts into the telescopic groove. After the pen cap is removed, the metal clip at the end of the pen cap can be engaged with the connecting sleeve, thus storing the pen cap and avoiding the problem of loss after removal. The entire storage process is quick and convenient, does not affect the overall use of the pen, and maintains the pen's simple appearance. Attached Figure Description

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example

[0033] like Figure 1-7 As shown, this utility model provides a technical solution: a magnetic stylus, including a stylus body, the stylus body is composed of a pen tip 1 and a pen barrel 2, the connection between the pen tip 1 and the pen barrel 2 is a columnar design, the columnar part is provided with an external thread 11, the pen barrel 2 is provided with a telescopic groove 21 on the periphery of the columnar part facing the pen tip 1, the telescopic groove 21 is located on the periphery of the external thread 11, a connecting sleeve 22 is slidably connected in the telescopic groove 21, the depth of the telescopic groove 21 is greater than the length of the connecting sleeve 22, the connecting sleeve 22 can be completely built into the telescopic groove 21 by the spring 221 contracting;

[0034] The outer thread of the external thread 11 is connected to the pen cap 3. The end face of the pen cap 3 away from the connection end is provided with a metal snap block 31. The length of the pen cap 3 is greater than the length of the pen tip 1, which ensures that the pen cap 3 can completely cover the pen tip 1 and provide protection.

[0035] The pen barrel 2 is threadedly connected to a charging protection cover 4 at the end away from the pen tip 1. The charging protection cover 4 has a snap-fit ​​groove 41 on the end face away from the connection end. This groove is located on the end face of the charging protection cover 4 away from the connection end and is used to cooperate with the metal snap-fit ​​block 31 on the pen cover 3. In addition to protecting the charging interface, the charging protection cover 4 also achieves connection and fixation with the pen cover 3 through the snap-fit ​​groove 41 and the magnetic block 42. Example

[0036] like Figure 1-7 As shown, this embodiment refines the design of the stylus based on embodiment 1 to improve its practicality and user experience. The cross-section of the pen tip 1 and the connecting sleeve 22 is "V" shaped, which is a conventional pen tip shape.

[0037] A spring 221 is provided on the inner side of the connecting sleeve 22. The two ends of the spring 221 are fixed to the connecting sleeve 22 and the end of the telescopic groove 21 away from the groove opening, respectively. The design of the spring 221 enables the connecting sleeve 22 to expand and contract when subjected to force, thereby realizing a certain adjustment or protection function.

[0038] The inner groove of the pen cap 3 is convex, and a protective pad 32 for contacting the pen tip 1 is fixed on the inner end face. When the pen cap 3 is placed on the pen tip 1, the protective pad 32 inside will contact and protect the pen tip 1 to prevent the pen tip 1 from being damaged or worn. The material of the protective pad 32 is usually a soft and wear-resistant material, such as rubber, to ensure effective protection of the pen tip 1.

[0039] The slot 41 and the metal slot block 31 are compatible; the slot 41 is equipped with a magnetic block 42, which attracts the metal slot block 31. When the pen cap 3 is not in use or stored, the pen cap 3 can be attracted to the charging protection cover 4 by the magnetic block 42. The magnetic attraction enhances the stability of the pen cap 3 connection and makes it easy for the user to quickly remove the pen cap 3 when necessary.

[0040] The working process of this utility model is as follows: Align the open end of the pen cap 3 with the connecting sleeve 22 and press it down gently. Since the connecting sleeve 22 is provided with a spring 221 inside, and the two ends of the spring 221 are respectively fixed to the connecting sleeve 22 and the end of the telescopic groove 21 away from the groove, the connecting sleeve 22 will retract inward under the action of the spring 221. At this time, the pen cap 3 is threadedly connected to the pen barrel 2, so it will not be lost and will not affect the overall appearance of the stylus.

[0041] After unscrewing the pen cap 3, the pen tip 1 is exposed, and the spring 221 of the connecting sleeve 22 returns to its original position, forming a "V" shape with the pen tip 1. Then, the metal snap-fit ​​block 31 of the pen cap 3 is brought close to the snap-fit ​​groove 41 of the charging protection cover 4 and snapped in. Since the snap-fit ​​groove 41 is equipped with a magnetic block 42, the magnetic block 42 will generate an attraction force on the metal snap-fit ​​block 31, thereby firmly attaching the pen cap 3 to the charging protection cover 4. This method can prevent the pen cap 3 from being lost and make it convenient for users to quickly remove the pen cap 3 when needed.

[0042] In summary, the magnetic stylus provided by this utility model, through its unique design, achieves functions such as protection, adjustment, and quick connection of the pen tip, thereby improving the practicality and user experience of the stylus.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
