[0033] Next, the embodiments of this specification are described in detail.

[0034] like Figures 1 to 3 As shown, the frame structure of the present application includes a first frame 1 and a second frame 2. The first frame 1 is snap-connected to the second frame 2 along the length direction of the second frame 2, and the end of the first frame 1 is connected to the end of the second frame 2. The first frame 1 includes a snap-fit ​​protrusion 12. The first frame 1 is snap-fitted to the second frame 2 through the snap-fit ​​protrusion 12. Such a configuration improves the convenience of connecting the first frame 1 with the second frame 2, thereby improving work efficiency and facilitating the transfer of the frame structure on site.

[0035] In one embodiment, the first frame 1 includes a frame body 11, a first folded edge 13 and a second folded edge 14. The engaging protrusions 12 are respectively arranged on the first folded edge 13 and the second folded edge 14. Preferably, the first folded edge 13 and the second folded edge 14 are respectively located on opposite sides of the frame body 11, and the first folded edge 13 and the second folded edge 14 are respectively attached to the second frame 2. Such an arrangement improves the convenience and stability of the engagement between the first frame 1 and the second frame 2 to prevent them from falling off.

[0036] Furthermore, the first folded edge 13 is extended from one side of the frame body 11 along the length direction of the second frame 2, and the second folded edge 14 is extended from the other side of the frame body 11 along the length direction of the second frame 2, and the first folded edge 13 and the second folded edge 14 have the same extension direction. This arrangement allows the first folded edge 13 and the second folded edge 14 to better clamp the second frame 2, thereby improving the stability of the engagement between the first frame 1 and the second frame 2.

[0037] Further integration Figures 4 to 6As shown, in one embodiment, in order to improve the manufacturing efficiency of the engaging protrusion 12 on the first frame 1, the engaging protrusion 12 is formed by being recessed from the outer surface of the first frame 1. Specifically, the engaging protrusion 12 includes a first protrusion 121 provided on the first folded edge 13 and a second protrusion 122 provided on the second folded edge 14. The recessed direction of the first protrusion 121 and the recessed direction of the second protrusion 122 are arranged opposite to each other. That is, the first protrusion 121 is recessed from the outer surface of the first folded edge 13 to the second folded edge 14 to form a protrusion that exceeds the inner surface of the first folded edge 13. The second protrusion 122 is recessed from the outer surface of the second folded edge 14 to the first folded edge 13 to form a protrusion that exceeds the inner surface of the second folded edge 14.

[0038] In one embodiment, the protruding height of the engaging protrusion 12 is not less than 5 mm and not more than 10 mm. Specifically, the height of the first protrusion 121 beyond the inner surface of the first folding edge 13 is not less than 5 mm and not more than 10 mm, and the height of the second protrusion 122 beyond the inner surface of the second folding edge 14 is not less than 5 mm and not more than 10 mm. Such a setting is to prevent the engaging protrusion 12 from having a poor engaging effect and easily falling off from the second frame 2 due to the protruding height of the engaging protrusion 12 being too small, that is, less than 5 mm. At the same time, it is also prevented that the engaging protrusion 12 is difficult to engage and is not easy to enter the engaging position on the second frame 2 due to the protruding height of the engaging protrusion 12 being too large, that is, greater than 10 mm, and the engaging protrusion 12 is not easy to withdraw from the second frame 2 when disassembling. The protruding height of the engaging protrusion 12 is preferably 7 mm to ensure the convenience of disassembling and assembling the first frame 1 and the second frame 2.

[0039] In one embodiment, the first frame 1 includes a mounting fold 15. The mounting fold 15 is extended from one side of the end of the frame body 11 along the length direction of the second frame 2, and has the same extension direction as the first fold 13 and the second fold 14. The mounting fold 15 is located between the first fold 13 and the second fold 14. In another embodiment, the mounting fold 15 and the second fold 14 are the same fold. Alternatively, the mounting fold 15 and the first fold 13 are located on opposite sides of the frame body 11, respectively, and the second fold 14 is located between the mounting fold 15 and the first fold 13.

[0040] Further integration Figures 7 to 9 As shown, in one embodiment, the end of the second frame 2 is located between the first folded edge 13 and the second folded edge 14, so that the first folded edge 13 and the second folded edge 14 clamp the second frame 2, thereby increasing the stability when the first frame 1 and the second frame 2 are engaged. The second frame 2 includes a snap-fit ​​groove 21. When the first frame 1 and the second frame 2 are engaged, the snap-fit ​​protrusion 12 is located in the snap-fit ​​groove 21.

[0041] To ensure that the engaging groove 21 can completely accommodate the engaging protrusion 12 and the stability of the engagement between the two, the recessed depth of the engaging groove 21 is greater than the protruding height of the engaging protrusion 12. At the same time, to prevent the engaging protrusion 12 and the engaging groove 21 from shifting or shaking due to the large gap between them, the gap between the engaging protrusion 12 and the engaging groove 21 is not greater than 0.5 mm to ensure the stability of the assembly of the two.

[0042] In one embodiment, the engaging groove 21 includes a first engaging groove 211 and a second engaging groove 212. Preferably, the first engaging groove 211 and the second engaging groove 212 are respectively arranged on opposite sides of the second frame 2 to facilitate the cooperation with the first protrusion 121 and the second protrusion 122. Specifically, when the first frame 1 cooperates with the second frame 2, the first protrusion 121 is located in the first engaging groove 211, and the second protrusion 122 is located in the second engaging groove 212.

[0043] In another embodiment, in order to ensure that the first frame 1 and the second frame 2 fit together during assembly, the position of the second engaging groove 212 is arranged to correspond to the position of the second protrusion 122 .

[0044] Further integration Fig.10 As shown, in one embodiment, the engaging groove 21 has a limiting plane 213 and a disassembly guide surface 214. The limiting plane 213 is arranged vertically, that is, arranged along the up and down direction of the second frame 2. The limiting plane 213 is connected to the disassembly guide surface 214, and the disassembly guide surface 214 is located above the limiting plane 213. When the engaging protrusion 12 is located in the engaging groove 21, the engaging protrusion 12 contacts the limiting plane 213 to prevent the engaging protrusion 12 from exiting the engaging groove 21. At the same time, when the engaging protrusion 12 is disassembled, the disassembly guide surface 214 provides a guiding direction for the engaging protrusion 12, which facilitates the easier disassembly of the engaging protrusion 12 and improves work efficiency.

[0045] The cross section of the engaging protrusion 12 is arc-shaped, and at least the two ends of the engaging groove 21 are also arc-shaped, so that when the first frame 1 and the second frame 2 are assembled, the engaging protrusion 12 and the engaging groove 21 fit each other. When the engaging protrusion 12 is located in the engaging groove 21, in the length direction of the second frame 2, the lateral side surface 123 of the engaging protrusion 12 contacts the limiting plane 213.

[0046] In one embodiment, the second frame 2 includes a guide surface 22. The guide surface 22 is used to guide the engaging protrusion 12, so that when the first frame 1 is assembled to the second frame 2, the engaging protrusion 12 is more easily engaged with the engaging groove 21. In the length direction of the second frame 2, the guide surface 22 is provided at the end of the second frame 2, and is closer to the frame body 11 than the engaging groove 21. The number of the guide surfaces 22 corresponds to the number of the engaging grooves 21, so as to facilitate the assembly and engagement of the first frame 1 and the second frame 2.

[0047] In the length direction of the second frame 2, the guide surface 22 and the disassembly guide surface 214 are arranged opposite to each other, so as to improve the disassembly and assembly efficiency of the first frame 1 on the second frame 2. The guide surface 22 is a guide arc surface, and the size of the guide surface 22 is not less than R3 and not greater than R5. Specifically, the radius of the guide surface 22 is not less than 3mm and not greater than 5mm. This arrangement is to prevent the guide surface 22 from having a poor guiding effect due to a radius that is too small, i.e., less than 3mm. At the same time, it is also to prevent the guide surface 22 from having a large guiding area due to a radius that is too large, i.e., greater than 5mm, which may conflict with other components.

[0048] The second frame 2 includes a mounting portion 23 . The mounting portion 23 is located at an end of the second frame 2 , and the mounting flange 15 is disposed at the mounting portion 23 .

[0049] In one embodiment, the first frame 1 is preferably made of metal, and the second frame 2 is preferably made of plastic. In addition, the first frame 1 can be fixed as a frame, and the second frame 2 can be used as a decorative strip to increase the aesthetics of the frame structure. The hardness of the snap-fitting protrusion 12 is greater than the hardness of the snap-fitting groove 21, so that the snap-fitting protrusion 12 can remain in its original state even after multiple disassembly, without wear and tear, and without failure, thereby increasing the service life of the snap-fitting protrusion 12.

[0050] In the frame structure of the present application, the length direction of the second frame 2 is the X direction, the length direction of the first frame 1 is the Y direction, and the up and down direction of the second frame 2 is the Z direction. Figure 1 .

[0051] The frame structure of the present application improves the convenience of the first frame 1 and the second frame 2 by cooperating with the engaging protrusion 12 and the engaging groove 21. And through the guiding effect of the guide surface 22, the engaging protrusion 12 is more easily slid into the engaging groove 21 from the end of the second frame 2, thereby improving the work efficiency and facilitating the on-site transfer of the frame structure. At the same time, since the hardness of the engaging protrusion 12 is greater than the hardness of the engaging groove 21, it is ensured that the engaging protrusion 12 will not be worn and will not fail after multiple disassemblies, thereby improving the service life of the engaging protrusion 12 and the stability of the first frame 1 and the second frame 2 when they are matched.

Although the present application has been disclosed as a preferred implementation mode as above, it is not used to limit the present application. Any technician familiar with this profession can make some changes or modify the technical contents disclosed above into equivalent implementation modes without departing from the scope of the technical solution of the present application. However, any simple modification, equivalent change and modification made to the above implementation modes based on the technical essence of the present application without departing from the content of the technical solution of the present application still fall within the scope of the technical solution of the present application.
