Although these solutions solve the three-proof problem, the assembly and maintenance of military three-proof notebook computers are more difficult. If the shell of the military three-proof notebook computer is disassembled for maintenance and inspection in special circumstances, the disassembly efficiency of the shell of the military three-proof notebook computer is greatly restricted. Therefore, there is still room for improvement. SUMMARY

[0008] By adopting the above technical scheme, the movable rod is driven to extend into the expansion hole to overcome the elastic force of the elastic member, so that the movable rod is separated from the fixed hole, and the computer body can be separated from the computer shell by being pulled out of the mounting groove; when the computer body is inserted into the mounting groove to make the expansion hole opposite to the fixed hole, the elastic member drives the movable rod to be clamped into the fixed hole, so that the computer body and the computer shell are fixed, the operation is simple, the work of disassembling or assembling the computer shell and the computer body by screwing is reduced, and the computer shell and the computer body are quickly disassembled and assembled.

[0016] By adopting the above technical scheme, the movable rod is rotated by the nut, the nut needs to be extended out of the fixed hole, and the nut is less likely to scratch the user and the computer body.

[0048] The implementation principle of the easy-to-maintain military three-proof notebook computer is:

[0049] When the computer body 1 and the computer shell 2 need to be disassembled, the screwdriver is first inserted into the polygonal slot 312, then the screwdriver drives the movable rod 31 to overcome the elastic force of the spring 33 and move towards the end chamber 12, and the limiting ring 32, the rotating ring 34 and the connecting hole 351 drive the limiting rod 35 to move towards the end chamber 12 until the movable rod 31 is disengaged from the fixed rod. Then the movable rod 31 is rotated and the rotation angle is less than 180°, at this time the limiting rod 35 limits the rotation of the spring 33 relative to the movable chamber 11, and the spring 33 rotates relative to the movable rod 31 through the rotating ring 34. Then repeat the above operation to drive the remaining movable rod 31 into the telescopic hole 13 and limit the movable rod 31 from extending out of the telescopic hole 13 by the limiting block 311, then the computer body 1 can be slid out of the mounting groove 21 to achieve the disassembly of the computer body 1 and the computer shell 2.

[0050] When the computer body 1 and the computer shell 2 need to be assembled, the computer body 1 is first inserted into the mounting groove 21 until the four telescopic holes 13 respectively face the four fixed holes 221. Then the screwdriver is inserted into the polygonal slot 312 and the movable rod 31 is rotated until the limiting block 311 faces the limiting slot 3111, and the limiting block 311 is automatically inserted into the limiting slot 3111 under the elastic force of the spring 33, and the movable rod 31 is driven to extend out of the telescopic hole 13 through the rotating ring 34 and the limiting ring 32 and then inserted into the fixed hole 221, and the limiting block 311 drives the closing strip 152 to press the side wall of the mounting groove 21 through the through hole 111. Then repeat the above operation to drive the remaining movable rod 31 to be inserted into the remaining fixed hole 221, and the rubber band 151, the closing strip 152 and the rubber strip 231 are in a compressed state, thereby sealing the storage groove 17.

[0051] By setting the computer body 1 to be inserted into the mounting groove 21 and fixed by the mounting structure 3, the closing strip 152, the rubber strip 231 and the rubber band 151, the computer body 1 and the computer shell 2 can be quickly disassembled, and the sealing performance of the storage groove 17 is improved, thereby protecting the components in the storage groove 17.

[0052] By setting the movable rod 31, the limiting ring 32, the spring 33, the rotating ring 34, the limiting rod 35, the fixed hole 221 and the telescopic hole 13, the movable rod 31 can be driven to extend into the telescopic hole 13 and rotated by using the screwdriver, thereby achieving the sliding connection of the computer body 1 and the computer shell 2. By rotating the movable rod 31 until the limiting block 311 faces the limiting slot 3111, the movable rod 31 can be driven to extend out of the telescopic hole 13 and be inserted into the fixed hole 221 under the driving of the spring 33, thereby achieving the fixation of the computer body 1 and the computer shell 2, which is simple to operate. At the same time, the rotating ring 34 and the limiting rod 35 limit the rotation of the spring 33, thereby reducing the damage of the spring 33 caused by rotation.

[0053] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
