Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof box safety, in particular to a double-layer rainproof door for an explosion-proof box. Background Art

[0002] An explosion-proof box is a safe container used to store flammable and explosive items or to be used in explosive environments. The explosion-proof box is designed with a special structure and materials that can effectively resist and isolate the impact of explosions and the spread of flames, protecting the safety of internal items and personnel. The protective door is an important component of the explosion-proof box and can be opened during operation to facilitate the inspection and maintenance of the equipment inside the box. It can also effectively prevent external fire sources from entering the explosion-proof box.

[0003] The existing explosion-proof box has only one layer of protective door to protect it, which makes it easy for the explosion-proof box to be soaked by rain on rainy days, causing the electrical equipment in the box to be soaked by rain, which may cause circuit short circuit and other faults, thereby increasing the risk of explosion. At the same time, since the explosion-proof box is difficult to clean and maintain, if the equipment fails and needs to be replaced or repaired, it also needs to be inspected and maintained by professionals, which greatly increases the cost. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing explosion-proof box has only one layer of protection door for protection, so that the explosion-proof box is easily soaked by rainwater on rainy days and has poor safety performance.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: a double-layer rainproof door of an explosion-proof box, comprising a connecting base, one side of the connecting base is fixedly connected to an explosion-proof electric box, a plurality of sleeves are fixedly connected to the bottom of the explosion-proof electric box, a protective box is sleeved on the outside of the explosion-proof electric box, the bottom of the protective box is fixedly connected to the explosion-proof electric box by a plurality of screws, and a plurality of the screws are threadedly connected to a plurality of sleeves respectively.

[0006] Through the above technical solution, the explosion-proof electrical box is protected by a double-layer rainproof door. The double-layer rainproof door can provide higher safety performance for the explosion-proof box. In dangerous situations such as explosions or fires, the double-layer structure can effectively isolate and slow down the spread of explosion energy and protect personnel from injury.

[0007] The utility model is further configured that the top of the protection box is rotatably connected to a rainproof door, and one side of the rainproof door is fixedly connected to a handle.

[0008] The utility model is further configured that a door panel is rotatably connected to the top of the explosion-proof electrical box, a protective door key hole is arranged on one side of the door panel, and an instrument is arranged above the door panel.

[0009] The utility model is further configured that a plurality of buttons are arranged below the instrument, and a plurality of signal lights are arranged above the instrument.

[0010] The utility model is further configured that a glass window is fixedly connected in the middle of the rainproof door, and the glass window faces the instrument and the signal light.

[0011] Through the above technical solution, users can observe signal lights and instruments without opening the rainproof door, which simplifies the operation steps, saves time and improves work efficiency.

[0012] The beneficial effects of the utility model are as follows:

[0013] The utility model provides a clamping sleeve at the bottom of the explosion-proof electric box, and uses screws to fix the protection box outside the explosion-proof electric box, so as to realize double-layer rainproof door protection for the explosion-proof electric box and the door panel, effectively preventing rain or other external environmental factors from entering the interior of the explosion-proof electric box, protecting the equipment, electrical appliances or other valuables in the box from damage, and the rainproof door effectively protects electrical appliances such as signal lights and buttons on the door panel of the explosion-proof electric box from water ingress or exposure to the sun, and at the same time, the user can directly observe the signal lights and instruments through the glass window on the rainproof door without opening or closing the rainproof door, so the operation is convenient and the practicability is high.
