[0021] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0022] Example 1

[0023] like Figure 1As shown, this embodiment provides a waterproof and sealed control box. The control box includes: a housing 1, a sealing gasket 2, and a control box cover 3; the housing 1 includes a bottom plate 4 and a side plate 5 arranged on the bottom plate 4, and a groove 6 is arranged at the upper end of the side plate 5; the sealing gasket 2 is arranged in the groove 6 at the top end of the side plate 5; and the control box cover 3 is arranged on the sealing gasket 2.

[0024] like Figure 2-3 As shown, in this embodiment, the sealing gasket 2 is a double T-shaped sealing gasket 7, which is assembled into the groove 6 by elastic compression of silicone rubber; the upper and lower sides of the double T-shaped sealing gasket 7 are respectively provided with waterproof grooves 8, and the left and right sides are provided with flat pads 9, which are placed between the top of the side plate 5 and the upper cover 3 of the control box. Specifically, the double T-shaped sealing gasket 7 is made of silicone rubber, and the structures on both sides and the middle can be compressed, elastically compressed and assembled in the groove 6, and fit completely with the inner wall of the groove 6, and the flat pads 9 fit with the smooth parts of the two ends of the groove 6; the structural design of the groove 6 can limit the double T-shaped sealing gasket 7, and the double T-shaped sealing gasket 7 will not move left and right, thereby achieving an efficient waterproof sealing effect, and the waterproof level can reach IP67 / IP69K.

[0025] like Figure 2-3 As shown, in this embodiment, a hole groove mounting plate 10 is provided on the outer side of the side plate 5, and a fastening screw 11 is provided at one end of the control box upper cover 3; the fastening screw 11 locks the control box upper cover 3 to the housing 1 through the hole groove mounting plate 10. Specifically, in the prior art, since the top of the side plate 5 of the housing 1 is smooth, when installing and fixing the control box upper cover 3, it is necessary to fine-process the sealing surface at the top of the side plate 5 and the sealing surface of the control box upper cover 3 to meet the sealing surface installation requirements, and when the control box upper cover 3 is tightened and fixed with the fastening screw 11, due to the elasticity of the sealing gasket 2, the situation of left and right movement may occur, and additional fixing is required, which increases the processing cost. The control box is fixed with a hole groove mounting plate 10 on the side of the side plate 5, which can realize that the control box upper cover 3 is fixed and tightened to the housing 1 by the fastening screw 11, and the sealing gasket 2 is installed in the groove 6, and the situation of left and right movement will not occur, and no additional sealing surface fine processing is required, which reduces the processing cost and improves the sealing and waterproof effect.

[0026] like Figure 4-5 As shown, in this embodiment, the sealing pad 2 also includes a waterproof sealing pad 12, and the waterproof sealing pad 12 is provided with waterproof grooves 13 on the upper and lower sides of the sealing pad 2.
