[0030] In this embodiment: A U-shaped frame 165 is installed between the drawer housing 16 and the base plate 167. Fixing bolts 166 are used to install the U-shaped frame 165 between the lower end of the drawer housing 16 and the base plate 167. Components are installed at the bottom of the base plate 167. When transporting the drawer housing 16, the U-shaped frame 165 reinforces the lower end of the drawer housing 16 and the periphery of the base plate 167 to prevent the base plate 167 from falling off the bottom of the drawer housing 16 due to uneven load distribution. A connecting plate 13 is installed inside the T-shaped groove 111, with threaded holes B132 aligned with threaded holes A112. A pad 141 with an internally threaded tube 142 is aligned to the bottom of the outer housing 11. After the internal threaded tube 142 is aligned with the threaded hole A112, bolts A143 are used to connect the internal threaded tube 142, threaded hole A112, and threaded hole A112. Inside hole B132, the outer housing 11 and connecting plate 13 are fixed. The pull-out housing 16 containing the parts is pushed into the outer housing 11. As the pull-out housing 16 is pushed in, the threaded hole 162 is aligned with the outside of the L-shaped rubber plate 115. The threaded connection hole A116 is aligned with the threaded connection hole 162. The rear plate 15 is pushed into the rear end of the outer housing 11. The threaded connection hole B152 is aligned with the threaded connection hole A116. The threaded end of bolt B153 is threaded into the threaded connection hole B152, the threaded connection hole A116 and the threaded connection hole 162 to fix the pull-out housing 16, the rear plate 15 and the inner corner block 114 for easy assembly. Conversely, by rotating bolt B153 in the opposite direction, the pull-out housing 16 can be easily pulled out from between the outer housing 11 and the connecting plate 13 for maintenance of the parts inside the pull-out housing 16.

[0031] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 2-4 The front end of the pull-out housing 16 is equipped with a display screen 18 and a button 19. The pull-out housing 16 is installed inside the outer housing 11 and the connecting plate 13. The display screen 18 and the button 19 are still inside the outer housing 11.

[0032] Dustproof nets A12 are installed on both sides of the outer surface of the external housing 11, and side grooves 168 are opened on both sides of the outer surface of the pull-out housing 16. The side grooves 168 correspond to the positions of the dustproof nets A12, which facilitates the circulation of air inside the pull-out housing 16.

[0033] The rear end of the pull-out housing 16 has a heat dissipation hole 164. The interior of the external housing 11 has a cooling fan 113 installed at the rear end of the T-shaped bottom groove 111. The cooling fan 113 is used to extract the heat from the interior of the pull-out housing 16.

[0034] A dust filter B151 is installed in the middle of the rear plate 15. The dust filter B151 is positioned corresponding to the cooling fan 113 and blocks impurities in the air.

[0035] In this embodiment: A dust filter B151 is installed in the middle of the rear plate 15. After the dust filter B151 is aligned with the cooling fan 113, the chassis 1 operates normally, and the cooling fan 113 starts to operate, drawing heat from inside the chassis 16 through the heat dissipation holes 164. The cooling fan 113 draws out the heat generated by the operation of the internal components of the chassis 16 and discharges the heat through the dust filter B151. Outside air passes through the dust filter A12 and the side groove 168. The dust filter A12 filters the air flowing into the chassis 16, and the dust filter B151 filters the outside air, preventing the chassis 1 from being exposed to outside air when it is not in use. Dust from the outside flows into the interior of the pull-out housing 16, affecting the normal use of the internal components. After the chassis 1 is assembled, the display screen 18 and buttons 19 are still inside the external housing 11. This prevents the liquid from accidentally spilling onto the outer surface of the chassis 1 and flowing into the interior of the pull-out housing 16 through the gap between the display screen 18, buttons 19 and the pull-out housing 16, thus affecting the normal operation of the components. After rotating bolt B153 in the opposite direction, the rear plate 15 and the pull-out housing 16 can be pulled out from the interior of the external housing 11, allowing for normal cleaning and maintenance of the cooling fan 113.

[0036] Working principle: The U-shaped frame 165 is installed between the lower end of the drawer box 16 and the base plate 167 using fixing bolts 166. The components are installed at the bottom of the base plate 167. When the drawer box 16 is moved, the U-shaped frame 165 is used to reinforce the lower end of the drawer box 16 and the periphery of the base plate 167 to prevent the base plate 167 from falling off the bottom of the drawer box 16 due to different loads.

[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.
