Description

Technical Field

[0001] This utility model belongs to the field of stylus technology, specifically relating to a retractable stylus. Background Technology

[0002] A stylus is an input device specifically designed for touchscreens or graphics tablets. Its main function is to simulate finger operation, while also providing more precise control and a variety of interactive experiences than fingers.

[0003] The working principle of a stylus is mainly based on the following three technologies: capacitive sensing technology (the principle is to simulate the conductivity of human fingers), electromagnetic induction technology (there is a coil inside, and an electromagnetic plate under the device screen emits an electromagnetic field. The stylus determines its position by sensing changes in the electromagnetic field), and active electrostatic technology (requires communication between the stylus and the device, which is achieved through Bluetooth or a dedicated protocol).

[0004] Currently, common styluses are not very portable due to their limited length.

[0005] A search revealed that a Chinese utility model patent with authorization announcement number CN222462030U discloses a "rotational telescopic structure and stylus", which includes a first body, a second body and a connecting component; in the retracted state, the second body is sleeved on the first body; the connecting component is connected to the first body and the second body respectively; wherein, when the first body rotates relative to the connecting component, the first body moves in a direction away from the connecting component.

[0006] While existing styluses, including those mentioned above, have telescopic features, their telescopic length is limited. Although multi-segment telescopic structures are used to address this limitation, they require individual adjustment, which is cumbersome and does not provide adequate safety protection for the stylus tip.

[0007] To address the aforementioned problems, this utility model proposes a retractable stylus. Utility Model Content

[0033] 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.

[0034] Please see Figures 1-5The present invention provides the following technical solution: a telescopic stylus, including a stylus body 1, and further including an outer tube 2 and a locking component.

[0035] Furthermore, by Figure 1 and Figure 2 As shown in this embodiment, the outer sleeve 2 is the same length as the stylus body 1, and the outer sleeve 2 is fitted onto the stylus body 1. Multiple positioning slots 11 are processed on the outer wall of the stylus body 1, which are evenly distributed along its length direction. The locking component cooperates with the positioning slots 11 to lock the stylus body 1 and the outer sleeve 2. With the above solution, when in use, the stylus body 1 integrates a touch chip and a battery (not shown in the figure), has a stylus tip at the front end, and a charging interface at the rear end.

[0036] Users hold the stylus body 1 and use the stylus tip to operate on the touch screen or graphics tablet.

[0037] When it is necessary to adjust the overall length of the stylus, first release the locking mechanism, then move the outer tube 2 along the axis of the stylus body 1. After the outer tube 2 is adjusted to the appropriate position, use the locking mechanism in conjunction with the positioning slot 11 to lock the stylus body 1 and the outer tube 2 to ensure the stability after adjustment.

[0038] The outer sleeve 2 of this utility model is designed to be the same length as the stylus body 1 and can slide freely along the axis of the stylus body 1. It is locked by the cooperation of the locking member and the positioning slot 11, which makes it convenient to adjust the length of the entire stylus, making it easy to use and carry. In addition, the outer sleeve 2 can cover the pen tip of the stylus body 1, providing safety protection for the pen tip and avoiding damage from accidental bumps, thereby improving the safety of the stylus body 1.

[0039] Preferably, by Figure 1 , Figure 2 and Figure 5 As shown, this embodiment also includes a protective cover 5, which has internal threads machined on the inner walls of both ends of the outer tube 2. The protective cover 5 is installed on the end of the outer tube 2 by thread engagement. With the above solution, when in use, the protective cover 5 is installed on the tail end of the outer tube 2 by thread engagement, which does not affect the operation on the touch screen or digital tablet by the stylus tip.

[0040] When not in use, adjust the position of the outer sleeve 2 so that it is completely aligned with the stylus body 1. Then, screw the protective cover 5 onto the head end of the outer sleeve 2 to further protect the stylus tip. (It is easy to understand that when not in use, installing the protective cover 5 at both ends of the outer sleeve 2 can also provide protection. However, when in use, the protective cover 5 unscrewed from the head end of the outer sleeve 2 should be properly placed to avoid loss.)

[0041] Preferably, by Figure 1 , Figure 2 and Figure 5 As shown in this embodiment, anti-slip texture 51 is processed on the outer wall of the protective cover 5. After adopting the above solution, the design of anti-slip texture 51 can significantly improve the friction between the user's fingers and the protective cover 5 during use, ensuring the reliability of rotating the protective cover 5.

[0042] Optionally, by Figures 1-3 As shown, in this embodiment, the locking component includes an unlock button 3 and a return spring 4. A positioning ring 21 is fixed on the outer wall of the outer sleeve 2. The unlock button 3 is pivotally mounted in the positioning ring 21, and a locking block 31 is fixed on the bottom surface of the unlock button 3. A through hole 22 is machined on the outer sleeve 2 for the locking block 31 to pass through. The protruding end of the locking block 31 is embedded in the positioning slot 11. The return spring 4 is fixed between the outer wall of the outer sleeve 2 and the unlock button 3. With the above solution, when it is necessary to adjust the position of the outer sleeve 2, the unlock button 3 is pressed. At this time, the return spring 4 retracts. Since the unlock button 3 is pivotally mounted in the positioning ring 21, the other end of the unlock button 3 drives the locking block 31 to move outward. When the locking block 31 is disengaged from the positioning slot 11, the outer sleeve 2 can move along the axial direction of the stylus body 1.

[0043] Once the outer tube 2 is adjusted to the appropriate position, release the unlock button 3. The reset spring 4 releases its elasticity to reset the unlock button 3. The locking block 31 is embedded in the positioning slots 11 at different positions to lock the stylus body 1 and the outer tube 2, ensuring stability after adjustment.

[0044] Preferably, by Figures 1-3 As shown in this embodiment, the through hole 22 is an oblong hole, and the length of the through hole 22 is 1.5 times the length of the locking block 31. With the above solution, when in use, the design of the through hole 22 can ensure that the locking block 31 can freely rotate in the through hole 22 when the unlock button 3 is flipped, avoiding the problem that the through hole 22 is stuck in the locking block 31 due to the small size, which would prevent the unlock button 3 from rotating.

[0045] Preferably, by Figures 1-3 As shown in this embodiment, a chamfer 311 is machined at the bottom of the locking block 31. With the above solution, the chamfer 311 has guiding and avoidance features when in use, ensuring that the locking block 31 can freely enter and exit the positioning slot 11 when the unlocking button 3 is flipped.

[0046] Preferably, by Figure 1 , Figure 2 and Figure 4As shown, this embodiment also includes: guide protrusions 23, two guide protrusions 23 are symmetrically fixed to the inner wall of the outer sleeve 2, and a guide groove 12 for the guide protrusions 23 to be embedded is processed on the outer wall of the stylus body 1. With the above solution, when the outer sleeve 2 is moved along the axial direction of the stylus body 1 during use, the outer sleeve 2 drives the guide protrusions 23 to move along the guide groove 12 to guide the outer sleeve 2, which further improves the stability of the outer sleeve 2 and can also effectively prevent the outer sleeve 2 from rotating relative to the stylus body 1.

[0047] Preferably, by Figure 1 , Figure 2 and Figure 4 As shown in this embodiment, the outer wall of the guide protrusion 23 abuts against the inner wall of the guide groove 12. With the above solution, the guide protrusion 23 and the guide groove 12 are fitted with a clearance fit during use, with a fit tolerance of <0.01mm. This ensures the stability of the fit and avoids the problem of large frictional resistance that makes it inconvenient to move the outer sleeve 2.

[0048] It should be noted that the stylus body 1 is a commercially available standard device with a built-in power switch. Those skilled in the art can make conventional selections according to their needs. Its working principle is common knowledge known to those skilled in the art and has been fully disclosed in the prior art, so it will not be elaborated on further in this article.

[0049] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0050] Components not described in detail in this article are existing technologies.

[0051] The working principle and usage process of this utility model: When in use, the stylus body 1 of this utility model integrates a touch chip and a battery, has a stylus tip at the front end, and a charging interface at the rear end.

[0052] Users can operate the touch screen or graphics tablet by holding the stylus body 1 and using the stylus tip.

[0053] When the overall length of the stylus needs to be adjusted, press the unlock button 3. At this time, the reset spring 4 retracts. Since the unlock button 3 is mounted in the positioning ring 21 by pivot rotation, the other end of the unlock button 3 drives the locking block 31 to move outward. When the locking block 31 is disengaged from the positioning slot 11, the outer sleeve 2 can move along the axis of the stylus body 1.

[0054] When the outer tube 2 is adjusted to the appropriate position, release the unlock button 3. The reset spring 4 releases its elasticity to reset the unlock button 3. The locking block 31 is embedded in the positioning slot 11 at different positions to lock the stylus body 1 and the outer tube 2, ensuring the stability after adjustment.

[0055] The outer sleeve 2 of this utility model is designed to be the same length as the stylus body 1 and can slide freely along the axis of the stylus body 1. It is locked by the cooperation of the locking member and the positioning slot 11, which makes it convenient to adjust the length of the entire stylus, making it easy to use and carry. In addition, the outer sleeve 2 can cover the pen tip of the stylus body 1, providing safety protection for the pen tip and avoiding damage from accidental bumps, thereby improving the safety of the stylus body 1.

[0056] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
