When the outer protective shell 3 is installed, the installation plate 14 is firstly welded at a position to be installed, then the outer protective shell 3 is placed at the fixing device 15 at the lower end of the front side surface of the installation plate 14 to be clamped, then a rotating button matched with the special-shaped groove 2801 is inserted into the longitudinal bevel gear 28, the longitudinal bevel gear 28 is driven to rotate through the rotating button, so that the transverse bevel gear 27 in meshed connection with the outer protective shell drives the longitudinal screw rod 26 below the longitudinal bevel gear to rotate, the linear slider 25 in threaded connection with the outer side of the longitudinal screw rod 26 is driven to move downwards through the longitudinal screw rod 26, the fixing device 15 (close to the upper side) outside is driven to move downwards to enter the outer protective shell 3 to form a clamping structure again, the outer protective shell 3 is installed in a driven mode, and the rotating button is taken down after installation is completed, so that a lawless person cannot rotate the longitudinal bevel gear 28 without the rotating button.
The working principle is as follows: when the device is used, according to the structure shown in the figures 1-9, firstly, when the outer protective shell 3 is impacted externally, the strength of the outer protective shell 3 is improved by using the transverse reinforcing rods 13 and the longitudinal reinforcing ribs 12 in the outer protective shell, deformation is avoided, meanwhile, the swing controller main body 1 extrudes the heat dissipation plates 6 on the upper side and the lower side, so that the push rods 16 on the outer surfaces of the heat dissipation plates 6 rotate, the push rods 16 push the sliding sleeves 17 at the bottom ends of the push rods to compress the extrusion springs 18 while rotating, the elastic action of the extrusion springs 18 is utilized to play a role in shock absorption, the amplitude of swing is reduced, parts and circuits in the controller main body 1 are prevented from being damaged, and when lawless persons forcibly destroy the protective door 5 and the front baffle 4, the outer protective shell 3 detects the behavior, the power supply of the electromagnet 24 is immediately disconnected, at the moment, the electromagnet 24 loses magnetism and loses the adsorption effect on the metal block 23, thereby outwards promote movable rack 21 to the position with the meshing of theftproof gear 19 under reset spring 22's the impetus again, utilize movable rack 21 and fixed rack 20 to carry out the block jointly to theftproof gear 19, make controller main part 1 can't take out outer protective housing 3, buzzer 11 sends the alarm sound simultaneously, thereby reach the purpose of theftproof, can't take off outer protective housing 3 from mounting panel 14 under the condition that does not have specific rotation button simultaneously, this is exactly this the theory of operation of this withstand voltage type PLC controller with alarming function.
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.
