A space for one end of the cover plate 7 to be inserted is formed between the stopper 64 and the baffle. That is to say, the baffle and the stopper 64 constitute the above-mentioned second plugging structure, refer to Figure 15 . After one end of the cover plate 7 is inserted upward between the stopper 64 and the baffle, through the interaction between the stopper 64 and the cover plate 7 and the interaction between the baffle and the cover plate 7, the cover plate 7 can be restricted from separating from the box body 1 along the thickness direction of the box body 1.

[0095] A fifth threaded hole 65 is provided at the lower edge position of the open end of the box body 1. A connection hole 30 corresponding to the fifth threaded hole 65 is provided on the cover plate 7. The fifth fastener 29 includes a screw or a bolt, and the cover plate 7 and the box body 1 can be firmly connected together by using the screw or the bolt, so as to realize the detachable connection between the cover plate 7 and the box body 1.

[0096] At least two connection holes 30 are provided. A fifth avoidance hole 31 is provided on one side of one of the connection holes 30 close to the second plugging structure. The fifth avoidance hole 31 is communicated with the connection hole 30. The size of the fifth avoidance hole 31 is larger than that of the connection hole 30, and the fifth avoidance hole 31 is located above the connection hole 30, refer to Figure 12 .

[0097] When it is necessary to remove the cover plate 7 from the box body 1, the fifth fastener 29 at the connection hole 30 without the fifth avoidance hole 31 can be removed, and the fifth fastener 29 at the connection hole 30 with the fifth avoidance hole 31 can be loosened but not removed. Then, a downward force is applied to the cover plate 7 to make the cover plate 7 slide downward relative to the box body 1, so that the cover plate 7 is disengaged from the second plugging structure. Then, the fifth fastener 29 is removed, and thus the cover plate 7 can be taken off. With such a setting, during the process of the cover plate 7 being disengaged from the second plugging structure, the problem of accidental slipping of the cover plate 7 can be effectively prevented, and accidental damage to the cover plate 7 can be avoided.

[0098] In the embodiment of the present invention, the electric control box body for an outdoor unit of an air conditioner further includes a cap 32. The cap 32 is arranged at the upper end of the box body 1, as Figure 1 and Figure 2 shown. The cap 32 is an integrally drawn part, and there is no seam on the side wall of the cap 32. Arranging the cap 32 at the upper end of the box body 1 can protect the upper end of the box body 1 to prevent rainwater and the like from entering the box body 1.

[0099] To reduce the weight of the box body 1, a hollow structure is arranged at the position where the upper end surface of the box body 1 coincides with the cap 32.

A clamping claw 72 is arranged on the fixing bracket 68, and the clamping claw 72 can be clamped with the clamping hole 63, so as to fix the radiator pipeline.

[0119] A fixing rubber block is coated on the outside of the radiator pipeline. When the clamping hole 63 on the U-shaped clamping piece 71 is clamped with the clamping claw 72 on the fixing bracket 68, the U-shaped clamping piece 71 contacts the rubber block, which can avoid the loss of the radiator pipeline and ensure the clamping force.

[0120] In the embodiment of the present invention, along the length direction of the box body 1, first bending parts 44 are respectively arranged at both ends of the cover plate 7. When the cover plate 7 closes the open end of the box body 1, both ends of the cover plate 7 are coated outside the box body 1.

[0121] Local protrusions 26 are designed at two corner positions of the cap 32 corresponding to the cover plate 7, as Figure 10 shown. The local protrusions 26 increase the space at the corner positions of the cap 32 to ensure that the first bending parts 44 on the cover plate 7 are inserted into the inside of the cap 32.

[0122] A curling structure 45 is arranged at one end of the cover plate 7 close to the cap 32, as Figure 15 shown, to improve the strength of the cover plate 7 and make it act with the stop piece 64 and the baffle.

[0123] A second bending part 46 is arranged at the end of the cover plate 7 far from the cap 32, as Figure 16 shown. The second bending part 46 is located outside the box body 1, and there is an included angle between the plane where the second bending part 46 is located and the height direction of the box body 1, and there is an included angle between the plane where the second bending part 46 is located and the thickness direction of the box body 1. That is to say, the second bending part 46 is inclined downward. When rainwater flows downward along the cover plate 7, the problem that rainwater enters the gap between the lower end of the cover plate 7 and the lower end of the box body 1 due to the infiltration effect can be avoided, and rainwater is prevented from entering the inside of the box body 1.

[0124] In a specific embodiment, the angle between the plane where the second bending portion 46 is located and the height direction of the box body 1 can be 55 degrees. That is to say, the angle between the plane where the second bending portion 46 is located and the thickness direction of the box body 1 is 35 degrees.

[0125] Flattened edges 33 are provided at the edges of both the first bending portion 44 and the second bending portion 46, which is beneficial to improving the structural strength of the cover plate 7 and preventing scratches to the operators and the wiring harness.
