Description

Technical Field

[0001] This utility model relates to the field of fixed structure technology, specifically a button fixing structure. Background Technology

[0002] With the continuous development of electronic technology, portable terminals such as blood pressure monitors and forehead thermometers have become the most common portable terminals in people's daily lives. As technology advances, users have increasingly higher requirements for the aesthetics and cost of product appearance. Buttons are one of the important components on portable terminals and other electronic devices, and they are used to realize human-computer interaction between electronic devices and users.

[0003] Electronic products typically have buttons mounted on their casings. These buttons are usually attached to positioning posts and fixed to the casing using a heat-fusion method. This method of button mounting has many drawbacks: button assembly is inconvenient, assembly can produce defective products, faulty buttons require the entire casing to be scrapped, and gaps between the button and the positioning post can cause misalignment. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a button fixing structure, which is easy to install, improves efficiency, meets the requirements of more uniform appearance gap and fit, and is convenient to use.

[0005] This utility model achieves its purpose through the following technical solution: A button fixing structure, characterized by comprising: a button assembly including a button body, wherein the button body is fixedly connected to symmetrical elastic arms, and the symmetrical elastic arms are respectively provided with elastic arm holes; a bottom shell assembly including a bottom shell, wherein the bottom shell is provided with button holes, the button body matches the button holes, and the bottom shell is fixedly connected to a set of positioning posts, wherein the symmetrical elastic arm holes match the corresponding positioning posts; and an upper shell assembly including an upper shell, wherein the upper shell matches the bottom shell. When the button body is inserted into the button hole, the positioning posts are simultaneously inserted into the elastic arm holes, the elastic arm holes and positioning posts are interference-fitted, and a notch is made through the elastic arm hole to give the elastic arm notch elastic properties. The tight fit between the elastic arm hole and the positioning post precisely limits and fixes the button body, restricting the forward, backward, left and right movement of the button body, maintaining the stability of the button body installation, with a simple structure and convenient assembly and disassembly. As an optimization, the button body is fixedly connected to an indicator protrusion, and the bottom shell is fixedly connected to a limiting arc rod. During installation, the indicator protrusion and the limiting arc rod are installed opposite each other, facilitating the installation of the button body.

[0006] As an optimization, the bottom shell is fixedly connected to symmetrical L-shaped plates, and the upper shell is fixedly connected to symmetrical slots. The symmetrical L-shaped plates match the symmetrical slots. When installing the upper and bottom shells, the L-shaped plates are aligned with the slots and inserted. The L-shaped plates and slots fit tightly, ensuring a stable connection between the upper and bottom shells and further enhancing the stability of the entire button fixing structure. Simultaneously, this connection method facilitates easy assembly and disassembly. When maintenance or component replacement is required, the upper and bottom shells can be quickly separated, improving work efficiency.

[0007] As an optimization, the bottom shell is fixedly connected to a set of guide ramps, and the upper shell is provided with a set of guide ramps, with the guide ramps matching the guide ramps. During the installation of the upper shell and the bottom shell, the guide ramps slide smoothly into the guide ramps. This design not only provides precise guidance for the installation of the upper shell and the bottom shell, ensuring that they can be accurately connected, but also plays a certain buffering role during the installation process, avoiding damage to the structure due to excessive installation force.

[0008] As an optimization, the upper housing is fixedly connected to a set of positioning protrusions, and the bottom housing is provided with a set of positioning slots. The set of positioning protrusions matches the set of positioning slots. The tight fit between the positioning protrusions and the positioning slots effectively prevents relative displacement between the upper housing and the bottom housing during use, thereby improving the reliability and service life of the entire button fixing structure.

[0009] As an optimization, each of the positioning slots is located directly below the corresponding guide groove.

[0010] As an optimization, the bottom shell is fixedly connected to symmetrical threaded holes, and the upper shell is fixedly connected to symmetrical threaded posts, with the symmetrical threaded posts matching the symmetrical threaded holes. When assembling this button fixing structure, the symmetrical threaded posts and symmetrical threaded holes are aligned, and then a suitable threaded fastener, such as a screw, is passed through the threaded post and screwed into the threaded hole to achieve a stable connection between the upper shell and the bottom shell. This connection method is simple to operate and results in a robust structure, effectively ensuring the stability of the button fixing structure during use. It is not easily loosened or separated by external forces, further improving the reliability and durability of the entire structure.

[0011] Compared with related technologies, the button fixing structure provided by this utility model has the following beneficial effects: (1) The button body of this mechanism is precisely limited and fixed by the interference fit of the elastic arm hole and the positioning column, which reduces the complex process of hot melt fixture, makes the appearance gaps uniform and beautiful, reduces the risk of button jamming, and makes after-sales disassembly and assembly convenient.

[0012] (2) The design of the positioning protrusion and the positioning slot effectively prevents the relative displacement of the upper shell and the bottom shell during use. This not only improves the overall stability of the button fixing structure, but also significantly extends its service life. Attached Figure Description

[0016] Example 1: A button fixing structure includes: a button assembly 1, including a button body 11, wherein the button body 11 is fixedly connected to symmetrical elastic arms 12, and the symmetrical elastic arms 12 are respectively provided with elastic arm holes 13; a bottom shell assembly 2, including a bottom shell 21, wherein the bottom shell 21 is provided with button holes 24, the button body 11 matches the button holes 24, and the bottom shell 21 is fixedly connected to a set of positioning posts 23, wherein the symmetrical elastic arm holes 13 match the corresponding positioning posts 23; and an upper shell assembly 3, including an upper shell 31, wherein the upper shell 31 matches the bottom shell 21. When the button body 11 is inserted into the button hole 24, the positioning posts 23 are simultaneously inserted into the elastic arm holes 13. The elastic arm holes 13 and the positioning posts 23 are interference-fitted, and a notch is made in the elastic arm hole 13 to give the elastic arm notch elastic properties. The elastic arm holes 13 and the positioning posts 23 are tightly fitted, precisely limiting and fixing the button body 11, restricting the forward, backward, left, and right movement of the button body 11, maintaining the stability of the button body 11 installation. The structure is simple and easy to assemble and disassemble. The button body 11 is fixedly connected to the indicator protrusion 14, and the bottom shell 21 is fixedly connected to the limiting arc rod 25.
