Technical Field
[0001] This utility model relates to the field of plastic shell technology, and in particular to a conductive plastic shell with metal shielding paint. Background Technology
[0002] In the field of modern electronic equipment, conductive plastic shells with metallic shielding coatings are widely used in various electronic products. With the continuous development of technology, the requirements for electromagnetic shielding performance in electronic products are becoming increasingly stringent. As a key shielding material, the combination of metallic shielding coatings with conductive plastic shells and related technologies have become a research hotspot. In existing technologies for conductive plastic casings with metallic shielding coatings, traditional processes are typically used for production. For example, when applying metallic paint to the plastic casing, simple spraying equipment and manual operation are mainly relied upon to achieve the shielding function by uniformly applying the metallic paint to the surface of the plastic casing. The technical principle is based on the conductivity of metallic paint, utilizing the metallic paint to form a continuous conductive layer on the plastic surface, thereby shielding electromagnetic signals. In the traditional assembly process of conductive plastic shells with metal shielding paint, the positioning of each component becomes difficult, making it hard to ensure precise alignment between the metal shielding paint and the plastic shell. Positional deviations are prone to occur, thus affecting the shielding effect. To address this issue, a conductive plastic shell with metal shielding paint is proposed. Utility Model Content
[0003] To overcome the above shortcomings, this utility model provides a conductive plastic shell with metal shielding paint, which aims to improve the problem in the prior art where the positioning of each component during the assembly process becomes difficult, making it hard to ensure precise alignment between the metal shielding paint and the plastic shell, and causing positional deviations that affect the shielding effect.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A conductive plastic shell with metal shielding coating includes an upper cover with a limiting groove inside, a guide mechanism inside, and a locking mechanism inside. The guide mechanism includes a lower cover with a limiting groove inside. The side wall of the lower cover is slidably connected to the inside of the upper cover. A U-shaped buckle and a fixing post are fixedly connected inside the upper cover. A locking block is fixedly connected inside the lower cover. The side wall of the U-shaped buckle is slidably connected to the side wall of the locking block. A grooved post is fixedly connected inside the lower cover. The side wall of the fixing post is slidably connected inside the grooved post. A support frame is fixedly connected inside the lower cover. As a further description of the above technical solution: The locking mechanism includes a guide post, a handle is fixedly connected to the side wall of the guide post, and the side wall of the handle is rotatably connected to the side wall of the upper cover. As a further description of the above technical solution: A slip ring is fixedly connected to the outer wall of the guide post, and the outer wall of the handle is rotatably connected to the side wall of the slip ring; As a further description of the above technical solution: The upper cover is provided with a sliding column inside, the side wall of the sliding ring is slidably connected to the inside of the sliding column, and the side wall of the sliding column is slidably connected to the inside of the limiting groove. As a further description of the above technical solution: A fixing ring is fixedly connected inside the sliding column, and the outer wall of the guide column is slidably connected inside the fixing ring. The fixing ring is in contact with the lower cover. As a further description of the above technical solution: A load-bearing column is fixedly connected inside the guide column, and the load-bearing column is slidably connected inside the limiting groove. As a further description of the above technical solution: The side wall of the load-bearing column is slidably connected inside the limiting groove 2, and the side wall of the guide column is sleeved with a spring. As a further description of the above technical solution: One end of the spring is fixedly connected to the side wall of the slip ring, and the other end of the spring is fixedly connected to the side wall of the fixed ring.
[0005] This utility model has the following beneficial effects: 1. In this utility model, the fixed post moves downwards aligned with the grooved post until the grooved post engages with the fixed post, and at the same time the U-shaped buckle engages with the locking block.

[0009] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0010] Reference Figures 1-4 This utility model provides an embodiment of a metal shielding conductive plastic shell, including an upper cover 1. The upper cover 1 has a limiting groove 14 inside, a guide mechanism inside, and a locking mechanism inside. The guide mechanism includes a lower cover 4, which allows the lower cover 4 to slide smoothly inside the upper cover 1, achieving a tight fit. The lower cover 4 has a second limiting groove 15 inside, and its sidewall is slidably connected to the inside of the upper cover 1. A U-shaped buckle 2 is fixedly connected inside the upper cover 1, providing an elastic connection during assembly. A fixing post 3 is fixedly connected inside the upper cover 1, and a locking block 5 is fixedly connected inside the lower cover 4. The sidewall of the U-shaped buckle 2 is slidably connected to the sidewall of the locking block 5, thereby enhancing the connection stability between the upper cover 1 and the lower cover 4. A grooved post 6 is fixedly connected inside the lower cover 4, and the sidewall of the fixing post 3 is slidably connected inside the grooved post 6. A support frame 7 is fixedly connected inside the lower cover 4, enabling the lower cover 4 to better withstand external pressure and force during assembly.
[0011] When assembling the upper cover 1 and the lower cover 4, first align the fixing post 3 inside the upper cover 1 with the groove post 6 inside the lower cover 4 and move it downwards. This causes the U-shaped buckle 2 to be squeezed and deformed by the locking block 5 until the groove post 6 and the fixing post 3 are engaged. At the same time, the U-shaped buckle 2 and the locking block 5 are engaged, making the connection between the components tight and providing a fixing effect. This completes the assembly of the upper cover 1 and the lower cover 4. The upper cover 1 and the lower cover 4 are assembled stably and precisely, ensuring the tightness of the overall structure and ensuring the structural stability of the entire metal shielding conductive plastic shell.
[0012] Reference Figure 5 The locking mechanism includes a guide post 8, a handle 9 fixedly connected to the side wall of the guide post 8, and the outer wall of the handle 9 rotatably connected to the side wall of the upper cover 1. A slip ring 10 is fixedly connected to the outer wall of the guide post 8, and the outer wall of the handle 9 rotatably connected to the side wall of the slip ring 10. A sliding post 11 is provided inside the upper cover 1, and the side wall of the slip ring 10 is slidably connected to the inside of the sliding post 11. The side wall of the sliding post 11 is slidably connected to the inside of the limiting groove 14. Under the drive of the slip ring 10, it moves along the direction of the limiting groove 14, providing a guiding function for the fixing ring 12. The inside of the sliding post 11 is fixedly connected to... A fixed ring 12 is attached, and the outer wall of the guide post 8 is slidably connected inside the fixed ring 12. The fixed ring 12 fits against the lower cover 4. A load-bearing post 13 is fixedly connected inside the guide post 8. The load-bearing post 13 is slidably connected inside the limiting groove 14, and the side wall of the load-bearing post 13 is slidably connected inside the limiting groove 2 15, so as to realize the positioning and locking of the lower cover 4. A spring 16 is sleeved on the outer wall of the guide post 8. One end of the spring 16 is fixedly connected to the side wall of the slip ring 10, and the other end of the spring 16 is fixedly connected to the side wall of the fixed ring 12, which enhances the overall structural strength of the product.
[0013] When it is necessary to lock the upper cover 1 and the lower cover 4, first align the load-bearing column 13 with the limiting groove 14 and move it downwards. When the fixing ring 12 is in contact with the inside of the upper cover 1, move the handle 9 downwards so that the guide column 8 drives the load-bearing column 13 downwards. At this time, the spring 16 is compressed and deformed, so that the load-bearing column 13 can reach the predetermined position more smoothly during the movement. Then, turn the handle 9 to drive the load-bearing column 13 to rotate into the reserved groove inside the limiting groove 15. The spring 16 loses compression and generates a pulling force on the load-bearing column 13, so that the load-bearing column 13 is engaged with the limiting groove 15, completing the locking work between the upper cover 1 and the lower cover 4. This prevents the upper and lower covers 4 from separating due to external force during use and ensures the normal operation of the product.
[0014] Working principle: When it is necessary to assemble the upper cover 1 and the lower cover 4, first align the fixing post 3 inside the upper cover 1 with the groove post 6 inside the lower cover 4 and move it downwards, so that the U-shaped buckle 2 is squeezed by the locking block 5 and deformed until the groove post 6 and the fixing post 3 are engaged, and at the same time the U-shaped buckle 2 and the locking block 5 are engaged, thus completing the assembly work between the upper cover 1 and the lower cover 4.
[0015] When it is necessary to lock the upper cover 1 and the lower cover 4, first align the load-bearing column 13 with the limiting groove 14 and move it downward. When the fixing ring 12 is in contact with the inside of the upper cover 1, move the handle 9 downward so that the guide column 8 drives the load-bearing column 13 downward. At this time, the spring 16 is compressed and deformed. Then, turn the handle 9 to drive the load-bearing column 13 to rotate into the reserved groove inside the limiting groove 15. The spring 16 loses compression and generates a pulling force on the load-bearing column 13, so that the load-bearing column 13 is engaged with the limiting groove 15, thus completing the locking work between the upper cover 1 and the lower cover 4.
[0016] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
