[0002] Today, plastic products are widely used, especially in the field of consumer electronics accessories, such as mobile phone cases and tablet cases. To enhance the appearance of these products, designers often incorporate unique, aesthetically pleasing, and personalized decorative elements into the casings, such as patterns of various shapes or colors. Currently, in terms of the fabric (artificial leather, genuine leather, cloth, soft metal film / sheet, soft plastic film / sheet, etc.) decoration of plastic casings, existing products generally consist of the fabric directly glued to the injection-molded casing. This leads to the following drawbacks in current technology:

[0003] Because it is glued, the reliability is not good. Especially under excessively high or low temperature conditions, it is easy to cause uneven surfaces, peeling, etc., and the edges of the decorative fabric are prone to curling up after bonding, which affects the removal of the decorative fabric and the firmness of the installation. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a one-piece molded high-strength plastic shell with the edges of the decorative shell pressed and hidden to avoid warping, and to facilitate installation and disassembly, so as to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a one-piece molded high-strength plastic shell, including a shell, a decorative shell, a pressure plate, and multiple reinforcing plates. The inner side of the shell is provided with a pressure groove, and a rectangular opening is provided at the center of the pressure groove. The decorative shell is placed in the rectangular opening, and the outer ring of the decorative shell is bent inward to form a flange. The flange is placed in the pressure groove, and the pressure plate is placed in the pressure groove and presses the flange tightly. The outer side of the pressure plate protrudes to form a pressing part, which is inserted into the decorative shell. The outer side of the decorative shell is flush with the outer surface of the shell. Multiple reinforcing plates are assembled inside the shell, and multiple connecting plates are installed between the reinforcing plates. One side of the reinforcing plate abuts against the inner side of the shell and the pressure plate.

[0006] As a preferred technical solution, multiple slots are provided on both sides of the inner surface of the housing, and both ends of the reinforcing plate are bent to form insertion parts, which are inserted into the slots.

[0007] As a preferred technical solution, the flange is provided with multiple positioning holes, and the inner wall surface of the pressure groove is provided with positioning grooves at the positioning holes. The outer surface of the pressure plate protrudes to form positioning parts at the positioning holes, and the positioning parts pass through the positioning holes and are inserted into the positioning grooves.

[0008] As a preferred technical solution, multiple fixing plates are installed on the inner side of the pressure plate. Each fixing plate protrudes to form a locking strip on its opposite surface. Each reinforcing plate on one side of the fixing plate is provided with a locking groove. One end of each locking strip is inserted into the locking groove and is locked and positioned with the locking groove. The cross-section of each locking strip is set in a hemispherical structure.

[0009] As a preferred technical solution, the reinforcing plate and the connecting plate are integrally molded, and both the reinforcing plate and the connecting plate are made of high-strength plastic material.

[0010] As a preferred technical solution, the inner side of the decorative shell is arranged to abut against the side of the extrusion part, and the outer side of the decorative shell is arranged to abut against the inner side of the rectangular opening.

[0011] The beneficial effects of this utility model are: the utility model has a simple structure.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a one-piece molded high-strength plastic shell, including a shell 1, a decorative shell 2, a pressure plate 3, and multiple reinforcing plates 4. The inner side of the shell 1 is provided with a pressure groove 10, and a rectangular opening 9 is provided at the center of the pressure groove 10. The decorative shell 2 is disposed in the rectangular opening 9. The outer ring of the decorative shell 2 is bent inward to form a flange 15, which is disposed in the pressure groove 10. The pressure plate 3 is disposed in the pressure groove 10 and presses the flange 15 tightly. A pressing part 14 is protruded from the outer side of the pressure plate 3 and is inserted into the decorative shell 2. The outer side of the decorative shell 2 is flush with the outer surface of the shell 1. Multiple reinforcing plates 4 are assembled inside the shell 1. Multiple connecting plates 5 are installed between the reinforcing plates 4. One side of the reinforcing plate 4 abuts against the inner side of the shell 1 and the pressure plate 3.

[0022] In this embodiment, multiple slots 12 are provided on both sides of the inner side of the housing 1, and both ends of the reinforcing plate 4 are bent to form insertion parts 8, which are inserted into the slots 12.

[0023] In this embodiment, the flange 15 is provided with multiple positioning holes, and the inner wall surface of the pressure groove 10 is provided with positioning grooves 11 at the positioning holes. The outer surface of the pressure plate 3 protrudes to form positioning parts 13 at the positioning holes. The positioning parts 13 pass through the positioning holes and are inserted into the positioning grooves 11. The flange can be positioned by the inserted positioning parts and positioning grooves, which avoids the outer side of the decorative shell from moving inward and increases the stability of the decorative shell after installation.

[0024] In this embodiment, multiple fixing plates 6 are installed on the inner side of the pressure plate 3. Each fixing plate 6 has a protruding strip 16 on its opposite surface. Each reinforcing plate 4 located on one side of the fixing plate 6 has a slot 7. One end of each strip 16 is inserted into the slot 7 and is engaged and positioned with the slot 7. The cross section of each strip 16 is hemispherical, so that the strip can be smoothly inserted into the slot.

[0025] In this embodiment, the reinforcing plate 4 and the connecting plate 5 are integrally formed, and both the reinforcing plate 4 and the connecting plate 5 are made of high-strength plastic material, which increases the firmness of the reinforcing plate and the connecting plate.

[0026] In this embodiment, the inner side of the decorative shell 2 abuts against the side of the extrusion part 14, and the outer side of the decorative shell 2 abuts against the inner side of the rectangular opening 9, so that the extrusion part can expand the interior of the decorative shell to ensure the flatness of the decorative shell after installation.

[0027] During installation, the decorative shell is inserted into the rectangular opening, while the flange on the decorative shell enters the pressure groove. As the decorative shell is installed, the pressure plate is placed into the pressure groove, and the pressing part is inserted into the interior of the decorative shell. The pressing part pushes the decorative shell outward until the outer surface of the decorative shell is flush with the outer surface of the housing, ensuring the flatness of the decorative shell after installation. The pressing part also holds the inner ring of the decorative shell in place, ensuring the stability of the decorative shell after installation. Furthermore, the pressing part also presses the outer side of the decorative shell against the inner side of the rectangular opening, ensuring the sealing between the pressing part and the rectangular opening. As the pressure plate enters the pressure groove, it presses the flange tightly. The positioning part on the pressure plate passes through the positioning port and inserts into the positioning groove, pressing and sealing the flange tightly, preventing the edge of the decorative shell from lifting.

[0028] With the above installation completed, the reinforcing plate can be inserted into the housing, and the inserts at both ends of the reinforcing plate can be inserted into the slots. As the reinforcing plate is inserted, the clips on the fixing plate can be inserted into the slots, so that the reinforcing plate can be connected with the pressure plate, which facilitates the synchronous installation and disassembly of the plate.

[0029] After the housing is assembled with another corresponding housing, the end faces of the two housings can abut together, and the end face of the other housing can abut against the insertion part, thereby automatically pressing the reinforcing plate onto the housing without the need for additional fixing structures, increasing the convenience of operation.

[0030] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
