Description

Technical Field

[0001] This application relates to the field of blood glucose meter technology, and more particularly to a faceplate structure and a blood glucose meter. Background Technology

[0002] A blood glucose meter is a medical device used to measure the concentration of glucose in the blood. It is mainly used for daily blood glucose monitoring by diabetic patients, but can also be used for blood glucose screening in healthy individuals.

[0003] The front of a blood glucose meter used in medical settings has a front cover, which is one of the main plastic parts that make up the main body of the device. The front cover, together with the middle support and bottom cover, forms the main body of the product used to store and protect internal components, tubing, and other parts.

[0004] In existing blood glucose meter structures, the front shell, middle support, and base are connected in pairs only by clips or screws. The connection structure is complex and repetitive, resulting in poor overall strength and stability of the device and a short product lifespan. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a face shell structure and a blood glucose meter, which aims to solve the problems of complex face shell connection structure and insufficient stability of existing blood glucose meters.

[0006] The technical solution adopted by this application to solve the technical problem is as follows: a shell structure, comprising: A front cover body, on which a backlight display hole and a button hole are formed, the button holes being spaced apart on one side of the backlight display hole; The first connecting post is symmetrically distributed on both sides of the backlight display hole, and the middle of each first connecting post is provided with a first through hole for screws to pass through. The second connecting post is symmetrically distributed on both sides of the key hole. The middle part of the second connecting post is provided with a second through hole penetrating the second connecting post. The top surface height of the second connecting post is greater than the top surface height of the first connecting post.

[0007] Furthermore, the faceplate body is also provided with several collapse fixing members, all of which are distributed on the same side of the button holes, and at least one of the collapse fixing members is provided between two adjacent button holes.

[0008] Furthermore, the cross-sectional profile of the collapse fixing member is circular or geometric.

[0009] Furthermore, the height of the top surface of the second connecting post is greater than or equal to the height of the shell body.

[0010] Furthermore, the button hole includes a switch hole and three function holes, the three function holes being arranged sequentially along the length of the faceplate body.

[0011] Furthermore, the face shell body is provided with at least four reinforcing ribs, which are arranged perpendicular to the face shell body and extend upward. The reinforcing ribs are connected to the outer wall of the second connecting column and are distributed at equal intervals.

[0012] Furthermore, the faceplate body is integrally formed.

[0013] Optionally, a downwardly recessed mounting groove is also formed on the faceplate body. The mounting groove is rectangular, and the backlight display hole is located in the mounting groove.

[0014] Optionally, several buckles are provided on the inner sidewall of the faceplate body.

[0015] Another technical solution adopted by this application to solve the technical problem is as follows: a blood glucose meter, including the shell structure as described above.

[0016] Compared with the prior art, the faceplate structure proposed in this application includes a faceplate body, a first connecting post, and a second connecting post. The faceplate body has a backlight display hole and button holes, with the button holes spaced apart on one side of the backlight display hole. The first connecting posts are symmetrically distributed on both sides of the backlight display hole, and each first connecting post has a first through hole in its center for a screw to pass through.

[0019] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0020] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0021] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0022] The outer casing of existing blood glucose meters is usually composed of three plastic parts: a base, a middle support, and a front cover. The inside of the blood glucose meter forms a space to accommodate components such as the endotracheal tube and circuit board. Two adjacent plastic parts are connected by screws or clips, which results in the corresponding internal connection structure occupying a lot of space inside the blood glucose meter. Furthermore, the device cannot be formed as a whole and has poor strength.

[0023] In this regard, such as Figure 1 and Figure 2As shown, this application proposes a faceplate structure, including a faceplate body 10, a first connecting post 20, and a second connecting post 30. The faceplate body 10 has a backlight display hole 11 and button holes. The button holes are spaced apart on one side of the backlight display hole 11. The first connecting posts 20 are symmetrically distributed on both sides of the backlight display hole 11, and each of the first connecting posts 20 has a first through hole 21 for a screw to pass through in its center. The second connecting posts 30 are symmetrically distributed on both sides of the button holes, and each of the second connecting posts 30 has a second through hole 31 penetrating through it in its center. The top surface height of the second connecting post 30 is greater than the top surface height of the first connecting post 20.

[0024] The faceplate body 10 is the plastic part of the blood glucose meter that directly faces the user. It is located on the top side of the blood glucose meter. The first connecting posts 20, which are of lower height, are located on both sides of the backlight display hole 11 and connect to the middle support of the blood glucose meter. The second connecting posts 30, which are of higher height, are located on both sides of the button hole and pass through the middle support to connect to the bottom shell screws, thereby realizing convenient fixation of the three main parts. Specifically, in this embodiment, the backlight display hole 11 on the faceplate body 10 is a rounded rectangle. The button hole is located below the backlight display hole 11. The button hole includes a circular switch hole 12 and three adjacently distributed function holes 13. The function holes 13 are arranged along the length of the faceplate body 10, and a corresponding button is provided below each hole.

[0025] To prevent the buttons from becoming loose after prolonged use, such as Figure 3 As shown, the faceplate body 10 is also provided with several collapsible fixing members 40. These collapsible fixing members 40 are all distributed on the same side of the key holes, with at least one collapsible fixing member 40 positioned between two adjacent key holes. During key assembly, the collapsible fixing members 40 are located between two keys or pass through pre-drilled holes on the keys. After the keys are assembled, the collapsible fixing members 40 are collapsed to fix the keys to the faceplate body 10, preventing the keys from loosening. Specifically, operators or automated equipment use a special tool to align with the collapsible fixing members 40. Under pressure, heat, or ultrasonic vibration, the collapsible fixing members 40 deform and soften, and under pressure, deform and spread outwards, forming a mushroom-shaped structure. The collapsed collapsible fixing members 40, like a lid, press against the back or edge of the keys, eliminating the gap between the keys and the faceplate, thus preventing the keys from loosening. In this embodiment, the cross-sectional profile of the collapsible fixing members 40 is circular or geometric.

[0026] In some embodiments, the top surface height of the second connecting post 30 is greater than or equal to the height of the shell body 10. This allows the second connecting post 30 to pass through the middle support and connect to the base.

[0027] In some embodiments, the faceplate body 10 is further provided with at least four reinforcing ribs 32. The reinforcing ribs 32 are arranged perpendicular to the faceplate body 10 and extend upward. The reinforcing ribs 32 are connected to the outer side wall of the second connecting column 30 and are evenly distributed. The reinforcing ribs 32 are used to support the taller second connecting column 30 and prevent the second connecting column 30 from collapsing or bending due to excessive height.

[0028] In some embodiments, the faceplate body 10 is integrally injection molded. After injection molding, the wall thickness of the faceplate body 10 is uniform, which reduces the production cost of the faceplate body 10 and enhances the structural strength of the faceplate body 10, thereby improving the overall impact resistance.

[0029] In some embodiments, a downwardly recessed mounting groove 14 is also formed on the faceplate body 10. The mounting groove 14 is rectangular, and the backlight display hole 11 is located in the mounting groove 14. The depth of the mounting groove 14 is 1.5mm. This design is not only aesthetically pleasing but also protects the display area from scratches. At the same time, it provides a stable mounting base for the backlight module, allowing the backlight module to be firmly set in the mounting groove 14 and reducing the vibration displacement of the display module.

[0030] In some embodiments, the inner wall of the faceplate body 10 is provided with several snap fasteners 15. The snap fasteners 15 are evenly distributed at the four corners of the faceplate body 10, so that the faceplate body 10 can also be connected to other components of the blood glucose meter through the snap fastener structure, further increasing the structural strength of the blood glucose meter.

[0031] like Figure 4 As shown in the figure, this application also proposes a blood glucose meter, including the shell structure described above. The shell structure includes a shell body, a first connecting post, and a second connecting post. A backlight display hole and a button hole are formed on the shell body. The button holes are spaced apart on one side of the backlight display hole. The first connecting posts are symmetrically distributed on both sides of the backlight display hole. Each of the first connecting posts has a first through hole in its center for a screw to pass through. The second connecting post has a second through hole in its center, and the top surface height of the second connecting post is greater than the top surface height of the first connecting post. When assembling the blood glucose meter, the first and second connecting posts of different heights extend to each layer of the blood glucose meter's components and are connected to them by screws, achieving a fixed connection between the multi-layered structure of the blood glucose meter, greatly improving the structural stability of the blood glucose meter and extending its service life.

[0032] It should be understood that the application of this application is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
