Technical Field
[0001] This utility model relates to the field of flat panel protective cases, and in particular to a flat panel protective case that is easy to adjust. Background Technology
[0002] With the widespread use of tablets, tablet cases have become an indispensable accessory. They not only protect tablets from bumps and damage but also integrate functions such as stands and pen holders to enhance usability. Among them, cases with capacitive pen storage structures are particularly popular because they prevent the pen from being lost or damaged. An adjustable tablet case is designed to better adapt to different usage needs through optimized structural design, especially in terms of flexible adjustment for capacitive pen storage and protection, meeting diverse usage scenarios. Most existing tablet cases with capacitive stylus storage structures consist of a fixed-size stylus slot inside the case or a flexible clip that matches a specific stylus model. The underlying technology utilizes the shape of the slot or the elastic clamping force of the clip to secure the stylus to the case, preventing it from falling out during transport or use. Some cases also include a simple pad inside the stylus slot to reduce friction between the stylus and the inner wall of the slot. However, the existing tablet protective cases have fixed capacitive pen storage structure dimensions, which can only accommodate capacitive pens of specific lengths. When using capacitive pens of different specifications, either the pen is too long to fit completely, resulting in exposed and easily damaged pen tips, or the pen is too short, leading to unstable fixation. Therefore, it is impossible to effectively protect the pen tips of various capacitive pens. To address this issue, an adjustable tablet protective case is proposed. Utility Model Content
[0003] To overcome the above shortcomings, this utility model provides an easily adjustable tablet protective case, aiming to improve the problem that the pen sleeve length of existing tablet protective cases is fixed and cannot be adapted to various specifications of capacitive pens, resulting in easy damage to the pen tip.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable tablet protective case includes a tablet computer with protective components on its left and right sides for providing protection. A support component is provided on one side of the protective component, a pen sleeve component is provided above the support component, and an adjustment component is provided on the side of the pen sleeve component for adjusting the position of the pen sleeve component, which is located inside the protective component. The protective assembly includes a rear protective shell and a front protective shell. One side of the back of the tablet computer is embedded inside the rear protective shell, and the frame of the rear protective shell is embedded inside the front protective shell to protect the front of the tablet computer. The adjustment assembly includes guide rails symmetrically distributed vertically. The side walls of the guide rails on both sides are fixedly connected to the upper part of the rear protective shell. The side walls of the guide rails on both sides are provided with multiple positioning holes, which are distributed in a linear array. A slider is slidably connected between the guide rails on both sides, and the side wall of the slider is fixedly connected to the outer wall of the pen sleeve assembly.
[0005] As a further description of the above technical solution: The slider has symmetrically distributed limiting balls on both sides inside. The outer wall of the front end of the limiting ball is slidably connected to the positioning hole. The side walls of the multiple limiting balls are fixedly connected to limiting plates. The limiting plates and the outer walls of the limiting balls are slidably connected to the slider.
[0006] As a further description of the above technical solution: A limiting spring is provided between the two limiting plates. The limiting spring is located inside the slider, and its two ends are fixedly connected to the side walls of the two limiting plates.
[0007] As a further description of the above technical solution: The pen sleeve assembly includes a pen tip sleeve, the sidewall of which is fixedly connected to the sidewall of the slider. Multiple anti-slip strips are fixedly connected to both the upper and lower sides of the pen tip sleeve, and the anti-slip strips are distributed in a linear array.
[0008] As a further description of the above technical solution: A fixing ring is provided on the side of the pen tip sleeve. The side wall of the fixing ring is fixedly connected to the outer wall of the rear protective housing. A capacitive pen is slidably connected to the fixing ring and the inner wall of the pen tip sleeve. The fixing ring is used to fix the position of the capacitive pen, and the pen tip sleeve is used to protect the pen tip of the capacitive pen.
[0009] As a further description of the above technical solution: The bracket assembly includes a rotating disk, which is rotatably connected to one side of the rear protective housing. A bracket ring is provided on one side of the rotating disk, and hand straps are fixedly connected to the side walls of both the rotating disk and the bracket ring.
[0010] As a further description of the above technical solution: The rotating disk and the support ring are provided with damping hinges at their bottom ends. The damping hinges are fixedly connected to the bottom of the rotating disk and the support ring at both ends. The damping hinges are used to connect the rotating disk and the support ring and allow the support ring to rotate.
[0011] This utility model has the following beneficial effects: In this invention, after using the capacitive pen, the user inserts it into the fixing ring, allowing the tip to enter the pen tip sleeve. The pen tip sleeve protects the pen tip. When inserting capacitive pens of different lengths, the user pinches the pen tip sleeve on both sides and pulls it, causing the bottom slider to slide along the guide rail and move it to the appropriate position. The spring then resets and pushes the limit plate to allow the ball to engage in the positioning hole, completing the adjustment of the pen tip sleeve position. This achieves the effect of compatible protection for capacitive pen tips of different lengths, solving the problem of traditional pen sleeves having a fixed length and being unable to adapt to various specifications of capacitive pens, which leads to easy damage to the pen tip. This improves the ease of use and equipment compatibility. Attached Figure Description

[0014] 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.
[0015] Reference Figure 1 - Figure 5An embodiment of this utility model is provided: an adjustable tablet protective case, including a tablet computer 5, protective components are provided on the left and right sides of the tablet computer 5, the protective components are used to protect the tablet computer 5, a support component is provided on one side of the protective component, a pen sleeve component is provided above the support component, an adjustment component is provided on the side of the pen sleeve component, the adjustment component is used to adjust the position of the pen sleeve component, and the pen sleeve component is located inside the protective component. The protective components are used to fully enclose the device to resist external impacts. They include a rear protective shell 1 and a front protective shell 4. The rear protective shell 1 is injection molded from TPU material. Its internal groove is embedded on one side of the back of the tablet computer 5 to support the device and protect the back. The front protective shell 4 is made of the same material and has a slot on the inner side of the frame. The frame of the rear protective shell 1 is embedded into the internal slot of the front protective shell 4 to form a closed structure to cover the front of the tablet computer 5 and protect the screen. The support assembly on one side of the protective component supports the equipment for multi-angle placement. It includes a rotating disk 2, made of ABS plastic, which is rotatably connected to the inside of the rear protective housing 1 via bearings, allowing for 360° rotation. A bracket ring 3 on one side of the rotating disk 2 is made of PP plastic and is semi-circular. Hand straps 8, made of nylon, are fixedly connected to the side walls of both the rotating disk 2 and the bracket ring 3, allowing the user to grip the device by inserting their hands during folding. Damping hinges 9 at the bottom of the rotating disk 2 and the bracket ring 3 use stainless steel shafts, with both ends fixed to the bottom of the rotating disk 2 and the bracket ring 3 by screws. These hinges provide damping force, allowing the bracket ring 3 to rotate and position freely within a 0-120° range. The pen sleeve assembly is used to store and protect the capacitive pen 7, including a pen tip sleeve 10. The pen tip sleeve 10 consists of a plastic outer shell and a silicone inner sleeve. The side wall is fixedly connected to the side wall of the slider 14 by injection molding. The interior is hollow and adapts to the shape of the pen tip. Multiple anti-slip strips 11 are integrally molded in a linear array on the upper and lower sides of the pen tip sleeve 10 to increase grip friction. The fixing ring 6 on the side of the pen tip sleeve 10 is injection molded from TPU material. The side wall is fixedly connected to the outer wall of the rear protective shell 1 by injection molding. The inner diameter is adapted to the capacitive pen 7. The fixing ring 6 and the inner wall of the pen tip sleeve 10 are slidably connected to the outer wall of the capacitive pen 7. The fixing ring 6 restricts the radial movement of the capacitive pen 7, and the pen tip sleeve 10 wraps around the pen tip to prevent collision damage. The adjustment component is used to change the position of the pen cap to adapt to capacitive pens 7 of different lengths. It includes symmetrically distributed guide rails 12, which are made of ABS plastic. The two side walls are fixedly connected to the upper part of the rear protective shell 1 by adhesive. Multiple positioning holes 13 arranged in a straight line on the side walls are used to cooperate with the positioning balls 17 for positioning. The slider 14 between the two guide rails 12 is made of PP plastic, and its outer wall slides with the inner wall of the guide rail 12. The left and right symmetrically distributed positioning balls 17 on both sides inside the slider 14 are made of nylon, and their front outer wall slides with the inner wall of the positioning hole 13 to achieve positioning. The side walls of the multiple positioning balls 17 are fixedly connected by adhesive to the limiting plate 16, which is made of ABS thin plate. The outer walls of the limiting plate 16 and the limiting balls 17 slide with the internal groove of the slider 14. The limiting spring 15 between the two limiting plates 16 is made of spring steel and is located inside the slider 14. Its two ends are welded and fixedly connected to the side walls of the two limiting plates 16 to provide continuous thrust to make the limiting balls 17 pop out. Specifically, when using this tablet case, the installation process is as follows: The user aligns the back of the tablet 5 with the inner groove of the rear protective case 1 and inserts it vertically, ensuring that the frame fits the groove. Then, the user aligns the frame of the front protective case 4 with the edge of the rear protective case 1 and pushes it horizontally so that the frame of the rear protective case 1 is fully inserted into the inner slot of the front protective case 4, completing the assembly. At this point, the tablet 5 is completely enclosed. When using the stand, the user moves the stand ring 3, which rotates outward around the damping hinge 9. At the same time, the rotating disk 2 can be rotated to adjust the direction until the stand ring 3 and the rear protective shell 1 form a suitable support angle. The damping force of the damping hinge 9 keeps the stand ring 3 at this angle. When the tablet computer 5 is placed on a flat surface, the stand ring 3 contacts the desktop to achieve support. When storing the capacitive pen 7, the user holds the capacitive pen 7 and inserts it horizontally into the fixing ring 6. Continuing to push, the tip of the capacitive pen 7 is inserted into the pen tip sleeve 10. The inner wall of the fixing ring 6 restricts the movement of the capacitive pen 7, and the pen tip sleeve 10 tightly wraps around the pen tip. When using capacitive pens 7 of different lengths, the position of the pen tip sleeve 10 is adjusted: the user pinches the anti-slip strips 11 on both sides of the pen tip sleeve 10 and pulls it left and right along the guide rail 12. The pen tip sleeve 10 causes the slider 14 to slide between the two guide rails 12. The limiting balls 17 on both sides inside the slider 14 are squeezed by the inner wall of the guide rail 12 and slide radially into the slider 14, causing the limiting plate 16 to move synchronously within the groove. Moving towards the center, the limiting plate 16 compresses the limiting spring 15, and the spring wire shortens axially to store elastic potential energy. When the slider 14 moves to the position that matches the length of the capacitive pen 7, the limiting ball 17 aligns with the corresponding positioning hole 13. The limiting spring 15 releases its elastic potential energy, pushing the limiting plate 16 to reset to both sides. The limiting plate 16 drives the limiting ball 17 to slide outward radially, and the front end is embedded in the positioning hole 13 to form a lock. The slider 14 and the pen tip sleeve 10 are fixed. At this time, after the capacitive pen 7 is inserted, the pen tip just completely enters the pen tip sleeve 10, realizing the adaptation and protection of capacitive pens 7 of different lengths. After the operation is completed, the pen tip sleeve 10 can be pulled in the opposite direction to adjust the position.
[0016] Working principle: When using this tablet case, the user inserts the tablet 5 into the rear protective shell 1, and then clips the frame of the front protective shell 4 into the rear protective shell 1, thus completing the assembly of the protective shell. The user can then rotate the rotating disk 2 as needed, and with the action of the damping hinge 9, the stand ring 3 can be freely unfolded, allowing the tablet 5 to be placed on a flat surface for use. After using the capacitive stylus 7, the user can insert the stylus 7 into the fixing ring 6, so that the tip of the stylus 7 is inserted into the stylus tip sleeve 10. The stylus tip sleeve 10 protects the stylus tip. Different lengths of stylus 7 can be inserted... The user can manually pinch the upper and lower sides of the pen tip sleeve 10 and pull the pen tip sleeve 10. The displacement of the pen tip sleeve 10 will cause the slider 14 at its bottom to slide between the guide rails 12. At the same time, the limiting balls 17 on both sides inside the slider 14 will be squeezed by the outer wall of the guide rails 12, which will cause the limiting plate 16 to retract into the slider 14 and compress the limiting spring 15. When it moves to the appropriate position, the limiting spring 15 will push the limiting plate 16 to reset, and then the limiting ball 17 will be inserted into the positioning hole 13 on the side wall of the guide rail 12. This completes the adjustment of the position of the pen tip sleeve 10 and achieves the effect of compatible protection of pen tips of different lengths of capacitive pens 7.
