[0002] A display screen is a tool that displays electronic documents onto a screen via specific transmission equipment. It is one of the output devices of computers and other equipment. Existing display screens typically consist of a back cover, a middle frame, and a screen. The middle frame is fixed to the back cover, while the screen is attached to the middle frame. During the manufacturing process, a layer of Mylar is often applied between the screen and the middle frame to improve the display screen's stability, sealing, and display effect.

[0003] In existing technologies, fixing the mid-frame to the rear shell is a relatively cumbersome process. This process requires the use of both a dispensing fixture and a thermoforming fixture. First, the dispensing fixture is used to evenly apply AB adhesive to the mating surfaces of the mid-frame and the rear shell; then, the dispensed mid-frame and rear shell must be quickly transferred to the thermoforming fixture for a one-minute thermoforming process. However, during the dispensing process, the dispensing fixture must operate continuously; otherwise, its nozzle will be damaged due to the hardening of the adhesive, thus affecting overall production efficiency. In addition, the operation of the thermoforming fixture is also relatively complex, increasing the difficulty of installation. Utility Model Content

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0027] This embodiment provides a quick-installation structure for the display screen frame, such as... Figures 1 to 8 As shown, the back shell 1 and the middle frame 2 are included. The back shell 1 includes a back plate 10. The four edges of the back plate 10 form side walls 11 vertically. A number of snap-fit ​​blocks 3, snap-fit ​​grooves 4 and guide grooves 5 are provided between the outer edge 20 of the middle frame 2 and the side wall 11. The snap-fit ​​grooves 4 and guide grooves 5 are arranged vertically on the outer edge 20 or side wall 11 of the middle frame 2 on the same side. The snap-fit ​​blocks 3 are arranged on the side wall 11 or outer edge 20 of the middle frame 2 on the other side and correspond to the snap-fit ​​grooves 4 and guide grooves 5. The snap-fit ​​blocks 3 abut against the guide grooves 5 and enter the snap-fit ​​grooves 4 by longitudinally pushing the guide grooves 5, so that the middle frame 2 is fixedly installed on the side wall 11 of the back shell 1.

[0028] In this embodiment, the middle frame 2 can be quickly and easily installed onto the back shell 1 using the snap-fit ​​block 3 in conjunction with the snap-fit ​​groove 4 and the guide groove 5. Users or manufacturers can complete the installation without additional tools or complex steps, effectively improving assembly efficiency. In actual production, the back shell 1 is generally made of metal, while the middle frame 2 is generally made of plastic. The back shell 1 is usually milled with several positioning holes for further fixing the middle frame 2 or for connecting external supports. Therefore, during the milling process, the snap-fit ​​block 3, snap-fit ​​groove 4, and guide groove 5 of this embodiment can be pre-milled along with the positioning holes or fixing structures, facilitating the subsequent fixed installation between the middle frame 2 and the back shell 1.

[0029] In this embodiment, the user presses the snap-fit ​​block 3 against the guide groove 5 and applies continuous pressure, which will press the snap-fit ​​groove 4 into the snap-fit ​​groove 4 through the guide groove 5. The structure is simple and easy to operate, and it can ensure a stable connection between the snap-fit ​​block 3 and the snap-fit ​​groove 4.

[0030] like Figure 2 and Figure 3 As shown, in this embodiment, the snap-fit ​​block 3 is disposed on the side wall 11, the snap-fit ​​groove 4 is disposed on the outer edge 20 of the middle frame 2 that matches the position of the snap-fit ​​block 3, and the guide groove 5 is disposed on the outer edge 20 of the middle frame 2, located below the snap-fit ​​groove 4. The guide groove 5 plays a role in initial positioning and guidance, enabling the middle frame 2 to be accurately aligned and inserted into the side wall 11 of the rear shell 1 during installation without the need for additional tools, making the installation process more convenient. The tight fit between the snap-fit ​​block 3 and the snap-fit ​​groove 4, as well as the guidance and support of the guide groove 5 for the snap-fit ​​block 3, jointly enhance the connection strength between the middle frame 2 and the rear shell 1. Of course, in other embodiments, the snap-fit ​​block 3 can also be disposed on the outer edge 20 of the middle frame 2, while the snap-fit ​​groove 4 and the guide groove 5 can be disposed on the side wall 11, and the user can also adjust the size according to the actual situation.

[0031] like Figure 3 and Figure 5 As shown, the snap-fit ​​block 3 is provided with a first inclined surface 30, and the guide groove 5 is provided with a corresponding second inclined surface 50. The first inclined surface 30 and the second inclined surface 50 cooperate with each other. In this embodiment, the first inclined surface 30 and the second inclined surface 50 allow the snap-fit ​​block 3 to slide along the ground when it abuts against the guide groove 5, which is beneficial for the snap-fit ​​block 3 to push the guide groove 5 into the snap-fit ​​groove 4.

[0032] like Figure 3 , Figure 5 and Figure 7 As shown, the first inclined surface 30 faces away from the side wall 11, while the second inclined surface 50 faces the side wall 11. In this embodiment, the first inclined surface 30 is disposed on the upper part of the snap-fit ​​block 3, and its orientation is away from the side wall 11. The second inclined surface 50 is disposed on the upper part of the guide groove 5, allowing the second inclined surface 50 to engage with the first inclined surface 30. Therefore, the second inclined surface 50 faces the side wall 11. In this embodiment, both the first inclined surface 30 and the second inclined surface 50 are flat inclined surfaces, which facilitates processing. In other embodiments, the first inclined surface 30 and the second inclined surface 50 can also be configured as curved surfaces, etc., according to actual needs.

[0033] like Figure 7 As shown, the inclination angles of the first inclined surface 30 and the second inclined surface 50 are both 45 degrees. In this embodiment, the consistency of the inclination angles of the first inclined surface 30 and the second inclined surface 50 helps to enhance the accuracy of guidance, and can better guide the snap-fit ​​block 3 to push against the guide groove 5 and enter the snap-fit ​​groove 4. In other embodiments, the inclination angles of the first inclined surface 30 and the second inclined surface 50 can also be adjusted.

[0034] like Figure 3 and Figure 7 As shown, the snap-fit ​​block 3 in this embodiment is elongated, which ensures a more stable connection between the snap-fit ​​block 3 and the snap-fit ​​groove 4. Since the snap-fit ​​block 3 has a first inclined surface 30 on its upper part, the cross-sectional shape of the snap-fit ​​block 3 is pentagonal. Correspondingly, the shape of the snap-fit ​​groove 4 is a cuboid that matches the shape of the snap-fit ​​block 3. The structure is simple and conducive to production and processing.

[0035] Furthermore, the snap-fit ​​blocks 3 are evenly distributed on the side wall 11, and the snap-fit ​​grooves 4 and guide grooves 5 are evenly distributed on the outer edge 20 of the middle frame 2. In this embodiment, the even distribution of the snap-fit ​​blocks 3, snap-fit ​​grooves 4, and guide grooves 5 ensures a stable connection between the middle frame 2 and the rear shell 1 at multiple points, which helps to optimize stress distribution and enhance the overall connection strength and stability.

[0036] Furthermore, this embodiment also includes several limiting blocks 6 and limiting grooves 7. The relative sliding between the middle frame 2 and the rear shell 1 is restricted by the limiting blocks 6 and the limiting grooves 7, which can further enhance the connection stability between the middle frame 2 and the rear shell 1 and ensure the product's service life and stability.

[0037] like Figure 3 As shown, in this embodiment, the limiting block 6 is disposed on the back plate 10, and the limiting groove 7 is formed on the inner edge 21 of the middle frame 2. The limiting block 6 and the limiting groove 7 can be pre-milled together with the snap-fit ​​block 3, snap-fit ​​groove 4 and guide groove 5, simplifying the installation process. Of course, in other embodiments, the position and size of the limiting block 6 and the limiting groove 7 can be adjusted.

[0038] Furthermore, in this embodiment, the limiting blocks 6 and limiting grooves 7 are evenly distributed, which can improve the stability of the overall structure of the middle frame 2 and the rear shell 1.

[0039] The usage process of this embodiment is as follows:

[0040] The snap-fit ​​groove 4 and guide groove 5 are provided on the outer edge 20 of the middle frame 2, with the guide groove 5 located below the snap-fit ​​groove 4. The snap-fit ​​block 3 is provided on the side wall 11, corresponding to the position of the snap-fit ​​groove 4. The user aligns the second inclined surface 50 of the guide groove 5 on the outer edge 20 of the middle frame 2 with the first inclined surface 30 of the snap-fit ​​block 3, and continues to apply pressure. The first inclined surface 30 of the snap-fit ​​block 3 pushes against the second inclined surface 50 of the guide groove 5, causing the snap-fit ​​block 3 to enter the snap-fit ​​groove 4 and complete the fixation. Figure 7 As shown, at this time, the limiting block 6 on the back panel 10 of the rear shell 1 is further limited in the limiting groove 7 of the inner edge 21 of the middle frame 2. By repeating the operation, the fixed installation of other positions on the middle frame 2 can be completed.

[0041] The directional terms used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0042] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
