[0016] 1. By providing an assembling mechanism, the front cover is covered on the surface of the PLC controller body, so that the inner wall of the front cover is sleeved on the surface of the step to position and assemble the PLC controller body and the front cover.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. In addition, the terms "first", "second", "third", "upper, lower, left, right", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. At the same time, in the description of the present utility model, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0025] The structure of an assembled PLC controller provided by the present utility model is as Figure 1 and Figure 2 shown, including the PLC controller body 1. A front cover 102 is provided on one side of the PLC controller body 1. A control button 103 is installed on the surface of the PLC controller body 1. The model of the control button 103 can be selected from the LA series. The control button 103 penetrates through the front cover 102 and extends to the outside of the front cover 102. An interface 101 is installed on the surface of the PLC controller body 1.

[0026] Furthermore, as Figure 2 and Figure 4 shown, an assembly mechanism 2 is provided between the PLC controller body 1 and the front cover 102. The interior of the assembly mechanism 2 includes an assembly component 201 and a mounting ear 202. Mounting ears 202 are fixed at the corner positions on the surfaces of the PLC controller body 1 and the interface 101. The adjacent mounting ears 202 are closely attached to each other. An assembly component 201 is provided between the PLC controller body 1 and the front cover 102. The assembly component 201 is composed of an elastic block 2011, a bayonet 2012, and a step 2013. A step 2013 is provided at the edge position on one side of the PLC controller body 1. The step 2013 is inserted and matched with the front cover 102. Elastic blocks 2011 are installed on both sides of the step 2013. Bayonets 2012 are provided on the surfaces of both sides of the front cover 102. The bayonets 2012 are snap-fitted with the elastic blocks 2011.

[0027] During use, cover the front cover 102 onto the surface of the PLC controller body 1, so that the inner wall of the front cover 102 sleeves onto the surface of the step 2013 to position and assemble the PLC controller body 1 and the front cover 102. Then press the front cover 102 to make the bayonet 2012 squeeze the elastic block 2011, and continue to press to make the bayonet 2012 snap to the outside of the elastic block 2011. Under the engagement of the bayonet 2012 and the elastic block 2011, the PLC controller body 1 and the front cover 102 are quickly assembled. When the PLC controller needs to be installed, the PLC controller can be placed at the installation location. Then insert the screw into the installation ear 202 to fix the installation ear 202 and the installation location with the screw. At this time, the screw not only installs the PLC controller, but also fastens the PLC controller body 1 and the front cover 102, eliminating the need for a separate screw to fix the PLC controller body 1 and the front cover 102, thus realizing the function of facilitating the assembly of the PLC controller.

[0028] Further, as Figure 2 shown, efficient heat dissipation mechanisms 3 are provided on both sides of the PLC controller body 1. The efficient heat dissipation mechanism 3 is composed of heat dissipation fins 301 and a heat dissipation component 302. Heat dissipation fins 301 are fixed on both sides of the PLC controller body 1, and a heat dissipation component 302 is arranged on the surface of the heat dissipation fins 301. The interior of the heat dissipation component 302 includes an air outlet hole 3021, a heat dissipation fan 3022, and a duct 3023. A heat dissipation fan 3022 is installed on one side of the PLC controller body 1 through a support frame. The model of the heat dissipation fan 3022 can be selected from the Y series. The input end of the heat dissipation fan 3022 is electrically connected to the output end of the control button 103. The heat dissipation fan 3022 is located on one side of the heat dissipation fins 301. A duct 3023 is fixed to the outside of the PLC controller body 1. One end of the duct 3023 extends to one side of the heat dissipation fan 3022, and the other end of the duct 3023 is fixedly connected to the surface of the heat dissipation fins 301. Air outlet holes 3021 are provided at the other ends of the duct 3023.

[0029] During use, heat is generated when the PLC controller is working. At this time, the heat is dissipated through the heat dissipation fins 301. If the temperature of the PLC controller is relatively high, the control button 103 can be operated to control the heat dissipation fan 3022 to start, so that the heat dissipation fan 3022 performs air-cooling on one side of the heat dissipation fins 301 to accelerate the heat dissipation of the heat dissipation fins 301. At the same time, part of the cold air is guided to one side of the heat dissipation fins 301 on the other side through the duct 3023 and discharged through the air outlet hole 3021 to cool the heat dissipation fins 301 on the other side, thus realizing the efficient heat dissipation function of the PLC controller.

[0030] Further, as Figure 3As shown in the figure, a shielding mechanism 4 is provided on one side of the interface 101. Inside the shielding mechanism 4, there are a shielding component 401, a magnet 402, and an arc-shaped strip 403. The arc-shaped strip 403 is fixed on the surface of the PLC controller body 1. One end of the arc-shaped strip 403 is fixed with a magnet 402. The shielding component 401 is arranged on the surface of the PLC controller body 1. Inside the shielding component 401, there are a magnetic sheet 4011 and a baffle 4012. The baffle 4012 is rotatably connected to the surface of the PLC controller body 1. The baffle 4012 covers the surface of the interface 101. The baffle 4012 and the arc-shaped strip 403 are concentric. A magnetic sheet 4011 is inlaid on one side of the baffle 4012. The magnetic sheet 4011 and the magnet 402 are magnetically attracted to each other.

[0031] When in use, if it is necessary to connect to the interface 101, the baffle 4012 can be toggled to make the baffle 4012 rotate along the arc-shaped strip 403, so that the interface 101 is exposed to the air. Then, the connecting wire is inserted into the interface 101. After the interface 101 is used up, the connecting wire can be unplugged, and the baffle 4012 is reset under the action of gravity and fixed by the magnetic attraction between the magnetic sheet 4011 and the magnet 402, so that the baffle 4012 shields the interface 101 to prevent dust or water stains from entering, so as to realize the shielding function of the PLC controller for the interface 101.

[0032] Working principle: When in use, first cover the front cover 102 on the surface of the PLC controller body 1, so that the inner wall of the front cover 102 is sleeved on the surface of the step 2013 to position and assemble the PLC controller body 1 and the front cover 102. Then press the front cover 102 to make the bayonet 2012 squeeze the elastic latch 2011, and continue to press to make the bayonet 2012 snap to the outside of the elastic latch 2011. Under the engagement of the bayonet 2012 and the elastic latch 2011, the PLC controller body 1 and the front cover 102 are quickly assembled. When the PLC controller needs to be installed, the PLC controller can be placed at the installation location, and then the screw is inserted into the installation ear 202 to fix the installation ear 202 and the installation location. At this time, the screw not only installs the PLC controller, but also fastens the PLC controller body 1 and the front cover 102, and there is no need to separately fix the PLC controller body 1 and the front cover 102 with screws, so as to realize the function of the PLC controller being easy to assemble, thereby improving the convenience degree during the assembly of the PLC controller.

[0033] When it is necessary to connect to the interface 101, the baffle 4012 can be toggled to rotate the baffle 4012 along the arc-shaped strip 403, exposing the interface 101 to the air. Subsequently, the connecting wire is inserted into the interface 101. After the interface 101 is used up, the connecting wire can be unplugged, and the baffle 4012 is reset under the action of gravity and fixed by the magnetic attraction between the magnetic piece 4011 and the magnet 402, so that the baffle 4012 shields the interface 101 to prevent dust or water stains from entering, thereby realizing the shielding function of the PLC controller for the interface 101 and extending the service life of the PLC controller.

[0034] When the PLC controller works, heat will be generated. At this time, the heat is exported through the heat dissipation fins 301. If the temperature of the PLC controller is relatively high, the control button 103 can be operated to control the heat dissipation fan 3022 to turn on, so that the heat dissipation fan 3022 performs air-cooling on the heat dissipation fins 301 on one side, accelerating the heat dissipation of the heat dissipation fins 301. At the same time, part of the cold air is guided to the side of the heat dissipation fins 301 on the other side through the air duct 3023 and discharged through the air outlet holes 3021 to cool the heat dissipation fins 301 on the other side, so as to realize the efficient heat dissipation function of the PLC controller, thereby improving the heat dissipation effect when the PLC controller is used, and finally completing the use of the PLC controller.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
