Description
Technical Field
[0001] The utility model relates to the technical field of capacitive pen protection devices, in particular to a capacitive pen protection cover. Background Art
[0002] Capacitive pen is a pen made of conductive material with conductive properties, used to touch the capacitive screen to complete the human-computer dialogue operation. Capacitive pen is an auxiliary device that uses conductive material to imitate the human body (usually fingers) to complete the human-computer dialogue. Tablet computers and other digital products are equipped with capacitive pens to facilitate users.
[0003] Since existing capacitive pens are generally slender and usually stored exposed, the pen body is easily bent or rubbed by external forces, resulting in reduced precision. At the same time, the tip of the capacitive pen is easily damaged by falling, collision and other factors, making it difficult to ensure its normal operation.
[0004] Therefore, a capacitive stylus protective cover is proposed to solve the above problems. Utility Model Content
[0005] The purpose of the utility model is to provide a capacitive pen protective cover in order to solve the above problems, thereby improving the problem that the existing capacitive pen has poor self-protection performance and is easily damaged by external factors.
[0006] The utility model achieves the above-mentioned purpose through the following technical scheme. The capacitive pen protective cover includes: a protective sleeve and an elastic telescopic structure. The elastic telescopic structure is installed inside the protective sleeve, and one end of the elastic telescopic structure penetrates to the outside of the protective sleeve.
[0007] Preferably, a positioning opening is provided on the surface of the protective sleeve, and the elastic telescopic structure comprises a fixing ring and an elastic pen clip, the fixing ring is fixedly connected to the inside of the protective sleeve, the fixing ring is arranged above the positioning opening, a sleeve is slidably connected to the inner side of the fixing ring, both top and bottom ends of the sleeve pass through to the outside of the fixing ring, a mounting cavity connected to the positioning opening is provided on the surface of the sleeve, a rubber spring in a compressed state is provided inside the mounting cavity, a positioning block slidably connected to the mounting cavity is provided at one end of the rubber spring, one end of the positioning block passes through the mounting cavity and is plugged into the positioning opening, a pressing sleeve is fixedly connected to the top end of the sleeve, a metal spring in a compressed state is provided between the pressing sleeve and the fixing ring, the elastic pen clip is fixedly connected to the surface of the protective sleeve, and a pressing block aligned with the positioning opening is fixedly connected to the surface of the elastic pen clip.
[0008] Preferably, a ring groove is formed at the bottom end of the pressing sleeve, and the top end of the metal spring contacts the ring groove, which can prevent the metal spring from being over-compressed, thereby ensuring that the metal spring is used within a reasonable pressure range.
[0009] Preferably, the local vertical cross-sectional shape of the positioning block extending to the outside of the installation cavity and the vertical cross-sectional shape of the pressing block are both matching right-angled trapezoids, and the inclined surfaces of the positioning block extending to the installation cavity and the pressing block are both facing downward, which can avoid the positioning block and the pressing block from interfering with the positioning port, thereby ensuring that the positioning block and the pressing block can normally enter and exit the positioning port.
[0010] Preferably, the charging hole on the surface of the protective sleeve has a vertical cross-sectional shape of a rectangle, which enables the capacitive pen to be charged and extended without disassembly, thereby improving the practicality of the capacitive pen protective sleeve.
[0011] Preferably, the inner wall corners of the charging hole are rounded, which can improve the safety factor for users and reduce the probability of the inner wall corners of the charging hole scratching the user.
[0012] Preferably, the top end of the socket is rotatably connected to a screw, and the bottom end of the screw passes through the inside of the socket, which can lock the capacitive pen more stably on the inner side of the protective sleeve. Even if the capacitor is fitted with the capacitive pen by the protective sleeve from a high place, the capacitive pen will not easily fall out of the socket, which not only reduces the probability of damage to the capacitive pen, but also reduces the probability of loss of the capacitive pen.
[0013] Preferably, the partial cross-sectional shape of the connection between the socket and the fixing ring is a rectangle, and the partial cross-sectional shape of the inner side of the fixing ring is a rectangle matching the socket, which can prevent the socket from rotating to ensure the normal operation of the entire elastic telescopic structure.
[0014] The beneficial effects of the utility model are:
[0015] 1. The design of a push-to-retract capacitive pen can completely hide the capacitive pen inside the protective sleeve when not in use, thereby reducing the probability of damage to the capacitive pen and effectively improving the protective performance of the capacitive pen, making it easier for users to store and carry. In addition, users only need to trigger the push sleeve and the elastic pen clip to remove and recycle the capacitive pen, which is simple and convenient to operate.
[0016] 2. Compared with the existing self-resetting capacitive pen protective cover that places a reset spring on the surface of the capacitive pen, this solution places a metal spring on the top of the capacitive pen, which not only avoids the capacitive pen being scratched by the metal spring, but also does not affect the normal wireless charging of the capacitive pen, thereby expanding the scope of application of the device;
[0017] 3. When the metal spring resets the capacitive pen, the charging hole is just connected to the wireless charging part of the capacitive pen. The user can magnetically attract the wireless charging part of the capacitive pen to the external wireless charging device, so that the capacitive pen can be charged without disassembly, thereby improving the practicality of the capacitive pen protective cover;
[0018] 4. The design of connecting the socket and the capacitive pen with screws can lock the capacitive pen more stably inside the protective sleeve. Even if the capacitor is fitted with the capacitive pen from a high place by the protective sleeve, the capacitive pen will not easily fall out of the socket, which not only reduces the probability of damage to the capacitive pen, but also reduces the probability of loss of the capacitive pen.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] When implementing: Figure 1-4 As shown, the capacitive pen protective cover comprises: a protective sleeve 1 and an elastic telescopic structure 2, wherein the elastic telescopic structure 2 is installed inside the protective sleeve 1, and one end of the elastic telescopic structure 2 penetrates to the outside of the protective sleeve 1.
[0026] like Figure 3 and Figure 4As shown, a positioning opening 11 is provided on the surface of the protective sleeve 1, and the elastic telescopic structure 2 includes a fixing ring 21 and an elastic pen clip 27. The fixing ring 21 is fixedly connected to the inside of the protective sleeve 1, and the fixing ring 21 is arranged above the positioning opening 11. A plug sleeve 22 is slidably connected to the inner side of the fixing ring 21, and both the top and bottom ends of the plug sleeve 22 penetrate to the outside of the fixing ring 21. A mounting cavity 221 connected to the positioning opening 11 is provided on the surface of the plug sleeve 22, and a rubber spring 23 in a compressed state is arranged inside the mounting cavity 221, and one end of the rubber spring 23 is provided with a plug sleeve 22 that is connected to the mounting cavity A positioning block 24 is slidably connected to the mounting cavity 221, one end of the positioning block 24 passes through the mounting cavity 221 and is plugged into the positioning port 11, a pressing sleeve 25 is fixedly connected to the top of the plug sleeve 22, a metal spring 26 in a compressed state is arranged between the pressing sleeve 25 and the fixing ring 21, an elastic pen clip 27 is fixedly connected to the surface of the protective sleeve 1, a pressing block 28 aligned with the positioning port 11 is fixedly connected to the surface of the elastic pen clip 27, and the design of fixing the elastic pen clip 27 to the surface of the protective sleeve 1 replaces the traditional nested connection method, making the elastic pen clip 27 more firm and more durable;
[0027] Compared with the existing capacitive pen protective cover with a reset function in which a reset spring is set on the surface of the capacitive pen, the design of setting the metal spring 26 for reset above the capacitive pen can not only avoid the probability of the metal spring 26 scratching the capacitive pen to ensure the integrity of the capacitive pen, but also will not hinder the normal wireless charging of the capacitive pen, thereby ensuring the normal operation of the capacitive pen.
[0028] like Figure 4As shown, the bottom end of the pressing sleeve 25 is provided with an annular groove 251, and the top end of the metal spring 26 is in contact with the annular groove 251; the local vertical cross-sectional shape of the positioning block 24 extending to the outside of the installation cavity 221 and the vertical cross-sectional shape of the pressing block 28 are both matching right-angle trapezoids, and the inclined surfaces of the positioning block 24 extending to the installation cavity 221 and the pressing block 28 are both facing downward; the surface charging hole 12 of the protective sleeve 1 has a rectangular vertical cross-sectional shape. When the metal spring 26 resets the capacitive pen, the charging hole 12 is just connected to the wireless charging part of the capacitive pen, and the user can magnetically attract the wireless charging part of the capacitive pen to the external wireless charging device, so that the capacitive pen can be charged and continued without disassembly, thereby The practicability of the protective cover for the capacitive pen is improved; the inner wall corners of the charging hole 12 are all rounded; the top of the socket 22 is rotatably connected with a screw 29, and the bottom end of the screw 29 penetrates into the inside of the socket 22; the design of connecting the socket 22 and the capacitive pen together with the screw 29 can lock the capacitive pen more stably on the inner side of the protective sleeve 1, even if the capacitor is fitted from a high place with the protective cover together with the capacitive pen, the capacitive pen will not easily fall out of the socket 22 at this time, which not only reduces the probability of damage to the capacitive pen, but also reduces the probability of loss of the capacitive pen; the partial cross-sectional shape of the socket 22 connected to the fixing ring 21 is a rectangle, and the partial cross-sectional shape of the inner side of the fixing ring 21 is a rectangle matching the socket 22.
[0029] When the utility model is used, the user first unscrews the pressing sleeve 25 from the insert sleeve 22 to expose the screw 29, and then inserts the end of the capacitive pen facing away from the pen tip into the insert sleeve 22, and makes the end of the capacitive pen facing away from the pen tip fit with the screw 29, and then rotates the screw 29 in the corresponding direction by a screwdriver, so that the screw 29 drills into the capacitive pen and the capacitive pen is spirally pulled into the insert sleeve 22 until the capacitive pen and the inner top wall of the insert sleeve 22 fit tightly, and finally the user screws the pressing sleeve 25 back to the surface of the insert sleeve 22, and the installation of the capacitive pen protective cover is completed at this time;
[0030] If the initial state of the capacitive pen is that the pen tip is outside the protective sleeve 1, when the user needs to store and protect the capacitive pen, the user only needs to press the elastic pen clip 27 in the direction of the protective sleeve 1, and the elastic pen clip 27 drives the pressing block 28 to penetrate into the positioning port 11 and squeeze the positioning block 24 in the positioning port 11 out of the positioning port 11. At this time, the metal spring 26 loses its obstruction, and the metal spring 26 quickly pushes back the pressing sleeve 25, and the pressing sleeve 25 drives the capacitive pen to move up quickly through the insertion sleeve 22 until the capacitive pen is completely moved into the protective sleeve 1. At this time, the protective sleeve 1 completely wraps the capacitive pen, which reduces the probability that the capacitive pen body is bent or the capacitive pen tip is damaged due to external forces such as collision and bending, effectively improves the safety factor of the capacitive pen when not in use, and has a relatively good improvement significance;
[0031] If the initial state of the capacitive pen is that the pen tip is inside the protective sleeve 1, when the user needs to use the capacitive pen, the user only needs to press down the pressing sleeve 25, and the pressing sleeve 25 moves the pen tip of the capacitive pen to the outside of the protective sleeve 1 through the plug sleeve 22. When the positioning block 24 is aligned with the positioning port 11, the rubber spring 23 quickly pushes the positioning block 24 into the positioning port 11, and firmly locks the plug sleeve 22 at this height. At this time, the user can use the capacitive pen stably.
[0032] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
