Description

Technical Field

[0001] The utility model belongs to the technical field related to electrical appliances, and in particular relates to an outdoor electrical appliance cabinet. Background Art

[0002] The electrical cabinet is made of steel and is used to protect the normal operation of components. The manufacturing materials are generally divided into two types: hot-rolled steel plates and cold-rolled steel plates. Cold-rolled steel plates are softer than hot-rolled steel plates and are more suitable for the production of electrical cabinets. Electrical cabinets are generally not large in structure and are involved in various electricity-using industries. When it comes to the use of various electronic devices, most of them require the assistance of electrical cabinets. Various electronic devices are installed inside to control circuits, etc. For some electrical equipment in outdoor places, electrical cabinets need to be installed outdoors to help use them, but outdoor electrical cabinets still have the following disadvantages in actual use:

[0003] First of all, since outdoor electrical cabinets are installed outdoors, they need to withstand the influence of the outdoor environment. Usually, in order to meet the heat dissipation needs, a large number of vents are opened on the side walls of the electrical cabinet to achieve the heat dissipation needs. Cooling fans can also be installed appropriately to help dissipate heat and ensure the normal operation of the internal electronic devices. However, among the outdoor environmental factors, the most likely to affect electronic devices is rain. Once rain enters the interior of the electrical cabinet, it is easy to cause electronic devices to malfunction. However, the vents opened to meet the heat dissipation needs cannot be omitted, which leads to certain impacts;

[0004] Secondly, when installing an outdoor electrical cabinet, what is more important is the sealing performance of the cabinet door and the cabinet body. Once the sealing is insufficient, it is easy for rainwater to leak in, which will also affect the normal operation of electronic devices. Utility Model Content

[0005] The utility model aims to provide an outdoor electrical cabinet, which solves the problems that the ventilation holes for heat dissipation may cause external rainwater to enter the interior of the electrical cabinet, and the cabinet body and the cabinet door are not sealed enough, which may easily cause rainwater to leak into the electrical cabinet, by arranging a cabinet door, a cabinet body, a sealing ring 1, a sealing ring 2, and a side frame.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0015] The utility model has the following beneficial effects:

[0016] The utility model solves the problem that the vents for heat dissipation may cause external rainwater to enter the interior of the electrical cabinet by providing a cabinet body and a side frame. The side frame is provided on the side of the cabinet body, a vent one is provided on the upper part of the cabinet body side wall, and a vent two is provided on the lower part of the side frame. Air circulation is achieved through the distribution of the vent one and the vent two. However, precisely because the vent one is higher than the vent two, and the position of the vent one is covered by the side frame, even if it rains outside and rainwater directly impacts the cabinet body, it will be blocked by the side frame and will not enter the vent one, and will not enter the interior of the cabinet. Secondly, even if rainwater enters the side frame through the vent two, it will flow out from the outlet and will not accumulate in the side frame. While ensuring ventilation and heat dissipation, no external rainwater will enter.

[0017] The utility model solves the problem of insufficient sealing of the cabinet body and the cabinet door, which easily causes rainwater to leak into the electrical cabinet, by arranging a cabinet door, a cabinet body, a sealing ring 1 and a sealing ring 2. The sealing ring 1 is arranged on the front side of the cabinet body, and the sealing ring 2 is arranged on the cabinet door. When the cabinet door is closed, the sealing ring 1 is embedded in the groove through the convex strip and fits tightly with the sealing ring 2, so that the cabinet door and the cabinet body are sealed. The unique structure of the convex strip and the groove can change the traditional flat sealing ring fitting structure, so that the sealing effect is better. BRIEF DESCRIPTION OF THE DRAWINGS
