[0002] In the prior art, a dental handpiece is a medical device commonly used in oral treatment. It is powered by compressed air to drive the wind wheel to rotate at high speed, thereby driving the dental needle to complete tasks such as drilling and grinding on the tooth. Currently, the dental treatment chairs on the market are mainly divided into top-mounted and bottom-mounted types, and the top-mounted dental treatment chairs and bottom-mounted dental treatment chairs use operating tables with different structures. After use, the top-mounted dental handpiece is placed in the instrument tray and positioned and supported using a special phone case pad.

[0003] In order to prevent cross infection, in principle, the use of dental handpieces is "one person, one machine, one use". However, due to cost issues, it is difficult to achieve "one person, one machine, one use" in practice. Therefore, when existing dental handpieces are cleaned and disinfected, the mobile phone case pad on the instrument hanger is generally removed and disinfected together. This requires that the mobile phone case pad can not only stably support the dental handpiece body, but also be easy to install and disassemble to cooperate with the cleaning and disinfection process of the dental handpiece. Summary of the invention

[0004] In order to solve the above problems, the utility model provides a mobile phone case pad which improves load-bearing stability, structural strength, cleaning convenience and adaptability.

[0006] To facilitate the taking action, the upper surface of the shell pad body is a first arc surface, which extends along the width direction of the shell pad body. The positioning groove is arranged on the first arc surface, and the inner wall surface of the positioning groove is a second arc surface, which extends along the length direction of the shell pad body.

[0007] In order to reduce potential risks during use, the edges of the positioning groove are rounded.

[0008] In order to enhance the structural strength of the shell pad, the truncated cone protrusion, the base and the shell pad body are integrally formed.

[0009] In order to provide multiple fixing options, a socket coaxial with the truncated cone protrusion is provided at one end of the truncated cone protrusion away from the base.

[0010] In order to optimize the buckling feel, the angle between the generatrix of the frustum protrusion and the horizontal plane is 45°-60°, and the height of the frustum protrusion is 9mm-13.5mm.

[0011] In order to ensure lightweight while ensuring structural strength, the shell pad body is a disk structure with an opening facing downward, and cross-arranged reinforcing ribs are provided in the disk structure. The reinforcing ribs are integrally formed with the shell pad body.

[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] Example 1.

[0022] like Figure 1-4 As shown, the mobile phone case pad described in this embodiment includes a case pad body 10, and a plurality of buckle pins 20 are provided on the lower surface of the case pad body 10, and the plurality of buckle pins 20 are arranged at intervals along the length and width directions of the case pad body 10, and each buckle pin 20 includes a conical protrusion 21 and a base 22, and the conical protrusion 21 is fixedly connected to the case pad body 10 through the base 22, and a stop groove 23 is formed at the connection position between the base 22 and the conical protrusion 21; a plurality of positioning grooves 30 are provided on the upper surface of the case pad body 10, and the plurality of positioning grooves 30 are arranged at intervals along the length direction of the case pad body 10.

[0023] When implementing it, Figure 4 As shown in (a), the shell pad body 10 of the mobile phone shell pad can be quickly and stably fastened with the corresponding structure on the instrument rack of the dental treatment chair through the buckle pins 20. Specifically: first, the conical protrusion 21 in each buckle pin 20 is used to push, and the corresponding buckle seat (not shown in the figure) on the instrument rack will be deformed under the pressure of the oblique side of the conical protrusion 21. When the back-stop groove 23 formed by the conical protrusion 21 and the base 22 is precisely matched with the buckle seat, the shell pad body 10 is stably fixed.

[0024] After the dental handpiece has been used or sterilized, medical staff can easily place it on the instrument hanger (not shown). At this time, the multiple positioning grooves 30 on the upper surface of the shell pad body play a key role. They ensure that the dental handpiece can be accurately placed, which is convenient for medical staff to quickly take out or replace it next time, so as to reduce unnecessary movement of the dental handpiece and effectively reduce the risk of cross infection.

[0025] In this embodiment, in order to optimize the buckling feel, the angle between the generatrix of the truncated cone protrusion 21 and the horizontal plane is 45°-60°, and the height of the truncated cone protrusion 21 is 9mm-13.5mm. In specific implementation, the angle between the generatrix of the truncated cone protrusion 21 and the horizontal plane is preferably 60°, and the height of the truncated cone protrusion 21 is preferably 13.5mm, that is, the inclined surface design of the truncated cone protrusion 21 provides a good guiding effect, making the buckling process smoother.

[0026] In some embodiments, Figure 1 and Figure 3 As shown, in order to facilitate the taking action, the upper surface of the shell pad body 10 is a first arc surface 40, and the first arc surface 40 extends along the width direction of the shell pad body 10. The positioning groove 30 is arranged on the first arc surface 40, and the inner wall surface of the positioning groove 30 is a second arc surface 31, and the second arc surface 31 extends along the length direction of the shell pad body 10.

[0027] With this structural design, the long sides of the shell pad body 10 are relatively thin, so that the mobile phone placed in the positioning groove 30 can be effectively supported by the shell pad body 10, and the thin edge design is also convenient for medical staff to perform the picking action. At the same time, the inner wall surface of the positioning groove 30 is designed as a second curved surface 31 to adapt to the shape of the dental mobile phone and provide a better fixing effect. In this embodiment, the first curved surface 40 and the second curved surface 31 can be a smooth arc surface, a parabola, or a curved surface formed by splicing multiple planes.

[0028] In some embodiments, Figure 1 As shown, in order to reduce potential risks during use, the edges of the positioning groove 30 are rounded. In this embodiment, the edges of the positioning groove 30 are rounded, and this design reduces the sharpness of the edges of the positioning groove 30, effectively preventing possible injuries to medical staff during the process of quickly taking or placing the dental handpiece, and further preventing the risk of infection caused by sharp edge cuts.

[0029] In some embodiments, in order to enhance the structural strength of the shell pad, the truncated cone protrusion 21, the base 22 and the shell pad body 10 are integrally formed. The integral forming reduces the risk of loosening or separation between the components (21, 22, 10) and improves the reliability of the product.

[0030] In some embodiments, in order to provide multiple fixing options, the end of the truncated cone protrusion 21 away from the base 22 is provided with a plug hole 211 coaxial with the truncated cone protrusion 21. Figure 4 As shown in (b), depending on the specifications of the supplier's instrument hanger, the installation can also be carried out by utilizing the interference fit between the boss on the buckle seat (not shown in the figure) and the socket 211, that is, the user can choose the most appropriate fixing method according to the actual situation, thereby improving the user experience.

[0031] In some embodiments, Figure 2 and Figure 3 As shown, in order to ensure the lightweight structure while ensuring the structural strength, the shell pad body 10 is a disk structure with the opening facing downward, and a cross-arranged reinforcing rib 50 is arranged inside the disk structure, and the reinforcing rib 50 is integrally formed with the shell pad body 10. With this structural design, the cross-arranged reinforcing rib 50 can effectively improve the structural strength and rigidity of the shell pad body 10, that is, the weight of the shell pad body 10 can be reduced without sacrificing the structural strength, meeting the lightweight design requirements.

[0032] In some embodiments, Figure 2As shown, a plurality of buckle pins 20 are arranged at intervals along the circumference of the shell pad body 10 at the edge of the lower surface of the shell pad body 10. With this structural design, compared with the arrangement at the center, the buckle pins 20 located at the edge of the shell pad body 10 allow medical staff to easily apply force at the edge of the shell pad body 10, thereby removing the buckle pins 20 more quickly and completely.

[0033] Further, such as Figure 1 As shown, notches 60 are provided on both sides of the shell pad body 10 in the length direction. The notches 60 can be used as gripping points for fingers, providing a starting point for disassembly when medical staff install or disassemble the shell pad body 10, thereby ensuring that subsequent disassembly is more convenient.

[0034] The mobile phone shell pad provided in this embodiment, through structural design, utilizes the anti-retraction groove formed by the conical protrusion and the base to ensure the stable positioning of the dental mobile phone when placed, avoiding the risk of displacement or falling off. At the same time, the structure optimizes the mechanical strength of the shell pad and maintains a compact design, making the product easier to disinfect and clean. In addition, the arc positioning groove has better compatibility, so that the shell pad can adapt to a variety of dental mobile phone models, enhancing the market application range of the product.
