block 24 to slide in the square groove 22, at the moment, along with the sliding of the trapezoidal block 24, the outer inclined plane of the trapezoidal block 24 can press the hinged moving assembly 25, the spring sleeve 93 of the moving assembly 25 is ejected out, the 255 in the round groove 254 at the bottom of the base block 253 is in contact with the ground, at the moment, the box body 1 can be moved through the rolling balls 255, the shock absorber 252 can be arranged to effectively perform shock absorption and buffering during moving, the arrangement of the reinforcing plate 26 can assist in supporting the lead screw 23, so as to improve the rotating stability of the lead screw 23, through the arrangement of the buffer component 3, when maintenance is needed, the pull ring 39 can be pulled, at the moment, the pull ring 39 drives the connecting rod 37 in the limit sleeve 35 to pull the bayonet pin 38, the bayonet pin 38 presses the limit spring 36 to shrink, the bayonet pin 38 is separated from the bayonet slot 42, at the moment, the box body 41 of the installation box 4 loses the limit, the box body can be detached from the transverse plate 32, and further equipment in the case can be maintained conveniently, through the arrangement of the buffer spring 31, the box body 41 of the installation box 4 can be subjected to shock absorption and buffering through the buffer spring 31, and the auxiliary roller 56 and the guide roller 34 are arranged and can be respectively matched with the screen 55 and the inner wall of the case body 1, so that force is guided to the buffer spring 31, the stability of shock absorption and buffering is further improved, the service life of equipment in the case is further prolonged, when short circuit occurs in the equipment and flames occur, at the moment, sensing signals of the temperature and humidity sensor 44 and the smoke sensor 46 are fed back to the DSP controller 43, the operation of the corresponding control drive fan 62 of DSP controller 43, the simultaneous control solenoid valve 64 is opened, the inside compression dry powder of solenoid valve 64 passes through injection pipe 65 blowout this moment, blow to every corner of quick-witted incasement portion through drive fan 62 scattering again, and then put out the flame effectively, prevent the emergence of extensive conflagration, further improvement the security of this incasement portion, set up manometer 63 simultaneously, can detect the pressure of compression dry powder incasement portion, thereby when compression dry powder incasement portion pressure is not enough, accessible signal transmitter 45 carries out remote alarm, and then guaranteed the normal operating of fire prevention mechanism 6, can conveniently open the door 10 that opens and shuts through setting up bridge type handrail 12.
