The working principle is as follows: when the box body structure for the communication equipment for installation and maintenance is used, firstly, the door body 7 is opened, the movable block 3 can slide on the first fixing plate 2 through the movable block 3, the connection effect of the pull rope 5 is matched, when the door body 7 is opened, the pull force effect of the pull rope 5 can drive the movable block 3 to slide on the first fixing plate 2 to one side close to the door body 7, on one hand, when the movable block 3 integrally moves outwards, the installation frame 10 can be driven to integrally move outwards, so that the device 21 can be conveniently taken and placed during installation and maintenance, meanwhile, through the toothed plate 20 fixedly arranged, when the installation frame 10 integrally moves outwards, due to the meshing transmission between the third gear 48 and the toothed plate 20, the worm 47 can be further driven to rotate, the worm wheel 46 can be further driven to rotate, due to the limit relation between the bulge 45 and the second installation strip 44, the sliding connection of the second installation strip 44 is matched, when the worm wheel 46 rotates, the second mounting bar 44 is driven to move, at this time, as shown in fig. 2, when the second mounting bar 44 moves, the movable plate 17 is further driven to move towards the side away from the device 21, and the second protrusion 50 slides inside the second groove 49, when the second mounting bar 44 moves initially, the second protrusion 50 moves at the horizontal section position of the second groove 49, at this time, the movable plate 17 is separated from one end of the third mounting bar 56, after the action of the movable plate 17 is lost, the third mounting bar 56 drives the third mounting bar 56 to separate towards both sides under the elastic force of the tension spring 57, at this time, the contact piece 53 is disconnected from the contact block 54, thereby avoiding the electric shock during maintenance, and then, when the movable plate 17 continues to move towards the side away from the device 21, at this time, the second protrusion 50 moves at the inclined section position of the second groove 49, due to the limiting effect of the first piston plate 40 and the second groove 49, the supporting plate 13 can be further driven to move downwards, at the moment, the device 21 moves downwards, the contact rod 51 is separated from the inside of the slot 52, at the moment, the device 21 can be fixed and released, and therefore maintenance or replacement of workers is greatly facilitated;
after the maintenance or replacement is completed, after the door body 7 is closed, the movable block 3 slides inwards on the first fixing plate 2 under the action of the elastic force of the spring 4, and in the inward movement process of the movable block 3, at this time, the toothed plate 20 and the third gear 48 are meshed for transmission, so that the worm 47 can be driven to rotate reversely, and further the worm wheel 46 is driven to rotate reversely, so as to realize the reset movement of the second mounting bar 44, at this time, as shown in fig. 1, when the second mounting bar 44 moves, the movable plate 17 can be further driven to move towards one side close to the device 21, and at the initial movement, the second bump 50 moves at the inclined section position of the second groove 49, due to the limiting action of the first piston plate 40 and the second groove 49, the support plate 13 can be further driven to move upwards, at this time, the device 21 is driven to move upwards, at this time, the contact rod 51 is inserted into the slot 52, and at this time, the fixed mounting of the device 21 can be completed, when the movable plate 17 continues to move to a side close to the device 21, the second protrusion 50 moves at the horizontal section of the second groove 49, and when the movable plate 17 collides with one end of the third mounting bar 56 and continues to move, due to the connection effect of the piston sleeve 55, the third mounting bar 56 can be further driven to move in the opposite direction and stretch the tension spring 57, and finally the contact piece 53 collides with the contact block 54, so that the circuit is connected, thereby further improving the working efficiency;
when the temperature inside the body 1 is too high, the electric telescopic rod 29 and the motor 25 can be driven to work, the electric telescopic rod 29 can further drive the contact block 54 to move left and right, when the tooth grooves 38 move left and right, on one hand, the connecting rod 27 can be further driven to move up and down due to the limiting function of the chute 37 and the first convex block 33, when the connecting rod 27 moves up and down, the first rack 23 can further move up and down, and the first mounting shaft 31 can be further driven to rotate back and forth due to the meshing transmission between the first rack 23 and the first gear 30, so that the first mounting bar 22 can swing up and down in an arc shape, meanwhile, the motor 25 can drive the heat dissipation fan 26 to work, so that the heat dissipation of the heat dissipation fan 26 in a swing type can be realized, the heat dissipation range is effectively improved, meanwhile, when the cross bar 32 moves left and right, the second mounting shaft 34 can further rotate back and forth due to the meshing transmission of the tooth grooves 38 and the second gear 39, since the first piston plate 40 is fixed to the inner wall of the piston sleeve 55, when the second mounting shaft 34 drives the second piston plate 41 to rotate back and forth in the piston sleeve 55, the change of the volume of the internal cavity of the piston sleeve 55 can be realized, and when the second piston plate 41 rotates clockwise, the volume of the cavity at the side of the air inlet pipe 43 and the air outlet pipe 42 is reduced, and the air flow can be discharged through the air outlet pipe 42 under the action of pressure by matching with the check valves arranged in the air outlet pipe 42 and the air inlet pipe 43, and is finally discharged from the spray head 15 through the installation tube 14, when the second piston plate 41 is rotated counterclockwise, the volume of the cavity on the side where the air inlet pipe 43 and the air outlet pipe 42 are located is increased to form negative pressure, thus, the external air flow can enter the cavity through the air inlet pipe 43, and the circulation can blow the periphery of the device 21, dust can be effectively prevented from adhering to the surface of the device 21, thereby further improving the heat dissipation efficiency.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
