While this traditional structure achieves a stable connection of the chassis, when replacing or maintaining internal components, users need to remove multiple screws and disassemble the corresponding panels. This process is not only time-consuming and labor-intensive, but also requires a high degree of precision, making it unsuitable for rapid assembly and disassembly.

[0004] Therefore, we proposed a pull-out chassis to solve the problems mentioned above. Utility Model Content

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.

[0025] Example 1: Please refer to Figures 1-3 A pull-out chassis includes a chassis 1, which includes an outer sheet metal plate 11 and an outer bottom plate 12 installed between the bottom ends of the outer sheet metal plate 11. An inner side plate 13 is installed between the inner sheet metal plate 11 and the outer bottom plate 12. An inner bottom plate 14 is installed between the bottom ends of the inner side plates 13. A front panel 18 and a rear panel 17 are respectively installed at the front end and the rear end of the inner side plates 13 and the inner bottom plate 14.

[0026] The front panel 18 is equipped with a display screen 2, a button 3 and a knob 4, and the rear of the front panel 18 and the periphery of the display screen 2 are equipped with LCD fixing studs 182.

[0027] Handles 111 are installed on both sides of the outer surface of the outer sheet metal plate 11, and external mounting holes 132 are opened on both sides of the outer surface of the inner side plate 13. The mounting position of the handles 111 is aligned with the external mounting holes 132.

[0028] A press-fit nut 15 is installed between the inner side plate 13 and the inner bottom plate 14. A press-fit stud 16 is embedded inside the inner bottom plate 14. A reinforcing rib 141 is installed at the top of the inner bottom plate 14 and inside the inner side plate 13, so that the inner bottom plate 14 can be used to support the components inside the chassis 1.

[0029] The inner side panel 13 has panel mounting holes 133 installed on both sides of its inner wall. The panel mounting holes 133 are located at the front and rear ends inside the inner side panel 13. The front heat dissipation hole 181 is connected and fixed to the panel mounting hole 133. The rear panel 17 is connected to the panel mounting hole 133 by a fixing hole 172. The positions of the panel mounting holes 133 that connect the rear panel 17 and the front heat dissipation hole 181 are different.

[0030] External mounting holes 132 are provided on both sides of the outer surface of the inner side plate 13, and side heat dissipation holes 112 are provided on both sides of the outer surface of the outer sheet metal plate 11. The side heat dissipation holes 112 are aligned with the corresponding side holes 131 to facilitate heat dissipation inside the chassis 1.

[0031] A network port 173 is installed at the rear end of the rear panel 17. An assembly foot 5 is installed between the bottom ends of the inner side panel 13 and the outer bottom panel 12. The assembly foot 5 is used to prevent the chassis 1 from slipping.

[0032] In this embodiment: the inner bottom plate 14 is provided with embedded press-fit studs 16 for fixing the printed circuit board (PCBA) and other necessary components. The inner side plate 13 is fixedly connected to the inner bottom plate 14 by press-fit nuts 15 to form an independent internal module. The bottom reinforcing rib 141 is designed to enhance the rigidity of the bottom plate so that it can withstand a large weight without deformation, while reducing the contact area with the outer sheet metal plate 11 to ensure that the inner module can be smoothly pulled out. The front panel 18 is embedded with LCD fixing studs 182 for fixing the liquid crystal display 2. After the buttons 3 and knobs 4 are assembled with the front panel 18, they are connected and fixed to the external mounting holes 132 of the inner module through the countersunk screw holes of the front panel 18. The inner module can be pushed in along the front of the outer sheet metal plate 11 to assemble the mesh port 173 and other components with the rear panel 17. Then, they are connected and fixed to the chassis 1 as a whole through the fixing holes 172. The feet 5 and handles 111 are installed to complete the overall assembly of the chassis 1.

[0033] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 2-4 The rear panel 17 has a corresponding hole 171 for the cooling fan at the rear end. The corresponding hole 171 for the cooling fan corresponds to the position of the cooling fan inside the chassis 1, which facilitates the cooling of the chassis 1.

[0034] The front panel 18 has a heat dissipation hole 181 on the front end and on one side of the display screen 2. The heat dissipation hole 181 is used to dissipate heat from the inside of the chassis 1.

[0035] In this embodiment: The chassis 1 adopts an independent base plate mounting structure to fix the printed circuit board (PCBA) and other necessary components required by the equipment. When replacing different models of equipment, only the corresponding base plate needs to be replaced without affecting the overall structure of the chassis 1. The inner base plate 14 is embedded with a press-fit nut 15 and a press-fit stud 16, which are used to fix and support the internal components and ensure that the surface of the base plate is flat and smooth, which facilitates the pull-out operation during assembly and disassembly. The inner side plate 13 forms a complete internal module of the chassis 1 with the press-fit stud 16 in the inner base plate 14 through a three-sided bending process. It is independent of the external structure. When maintenance is required, the internal module can be pulled out as a whole, which is simple and quick. The inner side plate 13 has corresponding side holes 131 on both sides to enhance the heat dissipation performance of the chassis 1.

[0036] Working principle: The pull-out structure is achieved by using a point-line contact method between the base plate and the outer sheet metal plate 11. Compared with the traditional flat base plate and outer sheet metal full contact design, it improves the overall rigidity of the base plate while reducing the contact area by 80%, which significantly reduces friction. The point-line structure is designed according to the assembly direction to ensure that the internal modules can be pulled out smoothly. When replacing or maintaining internal components, users can quickly disassemble the outer decorative sheet metal and then easily pull out the inner base plate 14.

[0037] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0038] Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
