The provided mounting plate 104 facilitates installation and disassembly, thereby facilitating the installation and replacement of components inside the computer housing 1. The provided sealing strip 105 makes the mounting plate 104 and the mounting groove 103 more sealed, improving the sealing performance of the device.

[0022] Specifically, as Figures 1-8 shown, two cavities 202 are formed inside the mounting plate 104. Two fixing plates 203 are respectively fixedly installed on the inner walls of the two cavities 202. Connecting grooves 204 are respectively formed on the sides of the two fixing plates 203. The inner wall of the connecting groove 204 is rotatably connected to a clamping strip 206 through a rotating shaft 205, and the side of the clamping strip 206 is slidably connected to the inner wall of the connecting groove 204.

[0023] In this embodiment: The clamping strip 206 is limited by the provided rotating shaft 205, and the connecting groove 204 limits the clamping strip 206, making it difficult for the clamping strip 206 to deviate.

[0024] Specifically, as Figures 1-8 shown, two clamping grooves 217 are respectively formed on the upper and lower inner walls of the mounting groove 103. The side of the clamping strip 206 is slidably connected to the inner wall of the clamping groove 217. A limiting post 207 is fixedly installed through the side of the clamping strip 206. An arc-shaped groove 208 is formed through the side of the fixing plate 203. The outer wall of the limiting post 207 is slidably connected to the inner wall of the arc-shaped groove 208.

[0025] In this embodiment: Through the provided clamping strip 206 and the clamping groove 217, the clamping strip 206 is inside the clamping groove 217, thereby fixing the mounting plate 104. The provided arc-shaped groove 208 and the limiting post 207 further limit the clamping strip 206, making the clamping strip 206 more stable.

Through grooves 214 are formed through the side surfaces at both ends of the moving strip 213. The inner walls of the two through grooves 214 are respectively slidably connected with the outer walls of the two cylinders 212.

[0029] In this embodiment: By providing the moving strip 213 and the through grooves 214, when the moving strip 213 moves, through the through grooves 214, the cylinders 212 and the fixing frames 211 are driven to move. The cylinders 212 slide on the inner walls of the through grooves 214, further driving the clamping strips 206 to rotate.

[0030] Specifically, as Figures 1-8 shown, a connecting plate 215 is fixedly installed on the bottom surface of the moving strip 213. The lower end of the connecting plate 215 slidably penetrates through the inner wall at the lower end of the cavity 202 and extends into the groove body 201. The bottom surface of the connecting plate 215 is fixedly connected with the top surface of the fixed block 216.

[0031] In this embodiment: By pulling the provided fixed block 216, the connecting plate 215 and the moving strip 213 are driven to move downward, further driving the clamping strip 206 to rotate out of the clamping groove 217, so that the mounting plate 104 can be conveniently disassembled.

[0032] The stabilizing mechanism 3 is arranged inside the mounting plate 104. The stabilizing mechanism 3 includes a stabilizing plate 303 located inside the mounting plate 104. An abutting groove 312 is formed on the top surface of the stabilizing plate 303. A limiting strip 304 is fixedly installed on the outer wall of the stabilizing plate 303. The stabilizing mechanism 3 is used for abutting and fixing the fixed block 216.

[0033] Specifically, as Figures 1-9 shown, a cavity 301 is formed on the inner wall of one side of the groove body 201. The side surface of the stabilizing plate 303 is slidably connected with the inner wall of the cavity 301 and the inner wall of the groove body 201. A limiting groove 302 is formed on the inner wall of the groove body 201. The inner wall of the limiting groove 302 is slidably connected with the side surface of the limiting strip 304.

[0034] In this embodiment: By providing the cavity 301, the stabilizing plate 303 can move. By providing the limiting groove 302 and the limiting strip 304, the stabilizing plate 303 is limited, making the movement of the stabilizing plate 303 more stable.

[0035] Specifically, as Figures 1-9As shown, a contact block 313 is fixedly installed on the inner wall of the contact groove 312. A stable groove 311 is formed on the bottom surface of the fixed block 216. The outer wall of the contact block 313 is slidably connected to the inner wall of the stable groove 311. The inner wall of the contact groove 312 is slidably connected to the side surface of the fixed block 216. Two moving grooves 305 are formed in the stabilizing plate 303 and the limiting strip 304. Buckles 306 are slidably installed on the inner walls of the two moving grooves 305 respectively. A clamping hole 307 is formed on one inner wall of the limiting groove 302. The two buckles 306 are clamped with the clamping hole 307.

[0036] In this embodiment: By providing the contact block 313, the contact groove 312 and the stable groove 311, the fixed block 216 is contact-limited, so that the fixed block 216 is not likely to move downward, ensuring that the card strip 206 is not easily loosened from the card slot 217. The provided buckles 306 and the clamping holes 307 are used to fix the stabilizing plate 303.

[0037] Specifically, as Figures 1-9 shown, control blocks 310 are fixedly installed on the side surfaces of the two buckles 306 respectively. Two sliding columns 308 are slidably installed on the top surfaces of the two buckles 306 respectively. Both ends of the plurality of sliding columns 308 are fixedly connected to the inner walls of both ends of the two moving grooves 305. Elastic members II 309 are slidably installed on the outer walls of the plurality of sliding columns 308. Both ends of the plurality of elastic members II 309 are fixedly connected to the inner walls of the two moving grooves 305 and the side surfaces of the two buckles 306 respectively.

[0038] In this embodiment: The sliding columns 308 are provided to limit the buckles 306, and the elastic members II 309 are provided to apply elastic forces to the two buckles 306.

[0039] Specifically, in this solution, when components inside the embedded rugged computer are damaged, press the control block 310 to drive two buckles 306 to move towards the middle and squeeze the second elastic member 309. The buckles 306 are disengaged from the card holes 307. Pull the control block 310 to drive the stabilizing plate 303 to move. The abutting grooves 312 and abutting blocks 313 on the stabilizing plate 303 move, and no longer limit and abut against the stabilizing grooves 311 and the fixing blocks 216. Pull the fixing block 216, and the fixing block 216 drives the connecting plate 215 and the moving bar 213 to move downward. The through groove 214 on the moving bar 213 drives the cylinder 212 and the fixing frame 211 to move. Due to the fixing of the clamping bar 206 by the rotating shaft 205 and the limiting of the clamping bar 206 by the arc-shaped groove 208 and the limiting post 207, the cylinder 212 moves on the inner wall of the through groove 214 and drives the clamping bar 206 to rotate. The clamping bar 206 rotates from the vertical state to the horizontal state. At this time, the clamping bar 206 moves out of the card slot 217, so that the mounting plate 104 can be conveniently and quickly disassembled without the need for specific tools, and the internal components will not be damaged, improving the maintenance efficiency and reducing the maintenance cost and time cost. After the maintenance is completed, pull the fixing block 216, install the mounting plate 104 in the mounting slot 103, loosen the fixing block 216, and under the elastic force of the first elastic member 210, the clamping bar 206 is clamped with the card slot 217 to fix the mounting plate 104. Push the stabilizing plate 303 to make the buckle 306 clamped with the card hole 307. At this time, the stabilizing plate 303 is fixed, and the abutting grooves 312 and abutting blocks 313 on the stabilizing plate 303 abut against and limit the fixing block 216 and the stabilizing grooves 311, making the fixing block 216 not easy to move, and further ensuring the stability of the clamping of the clamping bar 206 with the card slot 217.
