[0029] As attached Figure 1 The structure of the IP55 control box of the utility model is shown, which includes a panel assembly 1, a bottom box assembly 2 and screws 3 connecting the panel assembly 1 and the bottom box assembly 2. Figure 2 , Attachment Figure 3 As shown, the bottom box assembly 2 includes a box body 21, which has an opening 22. The edge surrounding the opening 22 is bent to form a flange 23 extending outward. In this embodiment, the flange 23 is outwardly expanded, and the angle between the flange 23 and the plane where the opening 22 is located is 45°. A connecting plate 24 connected to the box body 21 and extending outward is welded to the outside of the opening 22, and a plurality of connecting holes 241 are processed on the connecting plate 24. As shown in the attached figure, Figure 4 As shown, the panel assembly 1 includes a panel body, and the edge of the panel body is processed with mounting holes 11 corresponding to the connection holes 241. The screws 3 pass through the mounting holes 11 and enter the connection holes 241 to connect the panel assembly 1 and the bottom box assembly 2. Figure 5 As shown, the inner side of the panel body is coated with a jointless sealing ring 12 formed by spraying polyurethane foam. The polyurethane foam has the function of moisture-proof and waterproof, which can effectively isolate moisture from entering the interior of the control box, and avoid the elevator malfunction caused by water ingress into the control box. The convex edge 23 and the jointless sealing ring 12 form a seal, which effectively blocks the external water flow from entering the control box through the connection between the panel assembly 1 and the bottom box assembly 2, and avoids the problem that the elevator cannot operate normally due to water ingress. There are 10 connecting holes 241, which are distributed around the box body 21. The screws 3 are M4x16 countersunk screws. The panel assembly 1 and the bottom box assembly 2 are fixed and installed and tightened by 10 M4x16 countersunk screws, which enhances the sealing of the control box.

[0030] The panel body has a sound outlet 13, and a water flow baffle 4 is installed on the inner side of the panel body to isolate the external water flow from entering the sound outlet 13. The sound outlet 13 has two rows, upper and lower, as shown in the attached figure. Figure 6-8As shown, the water flow baffle 4 includes a stacked first baffle 41, a second baffle 42 and a third baffle 43. In this embodiment, the first baffle 41, the second baffle 42 and the third baffle 43 are all acrylic plates. Figure 9-11 As shown, the side of the first baffle plate 41 that is attached to the panel body has a vertical first waist-shaped countersunk hole 414 corresponding to the number of columns of the sound outlet holes 13, and the upper and lower ends of the first waist-shaped countersunk hole 414 are respectively processed with a first through hole 411 and a second through hole 412 that penetrates the first baffle plate 41, and a third through hole 413 is provided below the first waist-shaped countersunk hole 414, the second through hole 412 is connected to the sound outlet hole 13 above, and the third through hole 413 is connected to the sound outlet hole 13 below; the second baffle plate 42 is processed with a fourth through hole 421 that is connected to the first through hole 411, and a vertical second waist-shaped countersunk hole 424 is provided below the fourth through hole 421, and the upper and lower ends of the second waist-shaped countersunk hole 424 are respectively processed with a fifth through hole that penetrates the second baffle plate 42 The through hole 422 and the sixth through hole 423, the fifth through hole 422 is connected to the second through hole 412, and the sixth through hole 423 is connected to the third through hole 413; the third baffle plate 43 is processed with a seventh through hole 431 connected to the fourth through hole 421, and a vertical third waist-shaped countersunk hole 432 is processed below the seventh through hole 431, and the third waist-shaped countersunk hole 432 connects the fifth through hole 422 and the sixth through hole 423. The through holes and the waist-shaped countersunk holes form a number of channels in the water flow baffle plate 4, forming a sealed drainage sound system, and the sound can be emitted from the upper sound outlet hole 13 along the channel. If water flows in from the sound outlet hole 13, it will only flow out from the lower sound outlet hole 13 after flowing in the channel, and cannot enter the inside of the control box.

[0031] The panel assembly 1 includes a display window 14 and a button 15. A neutral silicone sealant is applied between the display window 14 and the panel body. The neutral silicone sealant is suitable for sealing the joints of various glass, metal, organic glass, etc. It has good moisture-proof and waterproof effects and can effectively prevent water outside the control box from entering the control box through the joint of the display window 14. A rubber ring is installed between the button 15 and the panel body to improve the waterproof performance of the control box.

[0032] The IP55 control box structure of the utility model has a convex edge 23 made of cold-rolled plate stretched out at the edge of the opening 22 of the box body 21 of the bottom box assembly 2, and a connecting plate 24 connected to the box body 21 is welded on the outside of the opening 22, which respectively cooperate with the jointless sealing ring 12 and the countersunk screw 3 on the panel assembly 1, and can block external water flow from entering the control box from the joint between the panel and the bottom box, thereby improving the sealing of the control box, and further effectively improving the waterproof performance of the control box. When the utility model is used for firefighter elevators, after firefighters carry fire-fighting equipment and a large number of water pipes into the car, the elevator will not be unable to operate normally due to water entering the control box, which will cause rescue interruption, and effectively assist firefighters to better carry out their work.
