This application claims the priority to Chinese Patent Application No. 202320279009.5 titled “outdoor cabinet”, filed with the China National Intellectual Property Administration on Feb. 15, 2023, which is incorporated herein by reference in its entirety.
The present application relates to the technical field of outdoor cabinets, and in particular to an outdoor cabinet.
With the improvement of people's living standards, the requirements for outdoor cabinets also increase. Since outdoor cabinets are in an outdoor environment where rainfall, snowfall, and strong winds may occur at any time, the requirements of waterproof performance and corrosion resistance of outdoor cabinets are high. A sealing and waterproof structure of the conventional outdoor cabinet generally employs a self-clamping sealing strip, the sealing strip is clamped into a flange of a door frame, and after the door is closed and a door lock is clamped well, the sealing strip is compressed to seal the outdoor cabinet.
However, when the above structure is used to seal the outdoor cabinet, the requirements for machining technology are high. Specifically, the flange needs to be carefully polished during machining and manufacturing to ensure the roughness of the flange. However, the space at the inner side of the flange is limited, leading to difficulty in polishing. If the flange is not polished well, the sealing strip may not be tightly clamped in the flange, resulting in water backflow and water leakage from the inside of the sealing strip. In addition, a transition arc weldment that connects a vertical flange and a horizontal flange may be deformed by a force after being welding, so it is necessary to strictly control the welding process to ensure flatness and surface roughness of the weldment at the arc corners after welding; otherwise, a gap may exist between the flange and the sealing strip after the sealing strip is clamped, which leads to water leakage. Therefore, in order to meet the machining requirements, a large amount of manpower and material resources are required to handle the machining process, which greatly increases the processing and manufacturing costs.
The main purpose of the present application is to provide an outdoor cabinet to solve the problem that when a conventional waterproof structure is used for sealing the outdoor cabinet, a large amount of manpower and material resources are required to handle the machining process in order to meet the machining requirements, which results in high processing and manufacturing costs.
In order to achieve the above purpose, an outdoor cabinet is provided according to one aspect of the present application. The outdoor cabinet includes a cabinet body, a cabinet door being connected to the cabinet body, a flange structure being arranged on the cabinet body, and a sealing structure, where the sealing structure includes a groove, and the flange structure is clamped in the groove; a flange drainage gap is provided at the flange structure, and an auxiliary drainage gap is provided at the sealing structure, the flange drainage gap and the auxiliary drainage gap are arranged in positional correspondence with each other, and flange drainage gap and the auxiliary drainage gap are configured to discharge water entering the groove.
In an embodiment, the sealing structure further includes a groove, the groove includes a first side plate, a bottom plate, and a second side plate connected in sequence. The auxiliary drainage gap is provided at the first side plate, and the second side plate abuts against the flange structure for sealing.
In an embodiment, the number of flange drainage gaps is at least two, the at least two flange drainage gaps are provided at a bottom of the flange structure, where at least one of the flange drainage gaps is located at a first side of the flange structure, and at least another one of the flange drainage gaps is located at a second side of the flange structure.
In an embodiment, the flange drainage gap includes a first drainage gap and a second drainage gap, and the auxiliary drainage gap includes a third drainage gap and a fourth drainage gap. The first drainage gap and the third drainage gap are arranged in positional correspondence with each other, the second drainage gap and the fourth drainage gap are arranged in positional correspondence with each other, and the first drainage gap is located above the second drainage gap.
In an embodiment, the flange structure includes a transition arc structure, a vertical flange, and a horizontal flange.

In an embodiment, the groove includes an arc section, the arc section is located at a bottom of the sealing structure, and the arc section is configured to match the transition arc structure.
In an embodiment, an area of the auxiliary drainage gap is greater than an area of the flange drainage gap.
In an embodiment, the groove is a U-shaped groove, and a distance between the first side plate and the second side plate gradually decreases along a direction away from the bottom plate.

Moreover, water backflow and water leakage can be effectively avoided. Even if the flatness and the surface roughness of the flange structure do not meet the requirements, and there is a clearance between the sealing structure and the flange structure after the sealing structure is sleeved on the flange structure, the water entering the groove can still be discharged through the flange drainage gap and the auxiliary drainage gap. Therefore, the requirements for the flatness and the roughness of the flange structure can be effectively reduced, thereby reducing the processing and manufacturing costs.

It should be noted that, when there's no conflict, the embodiments and features thereof in the present application can be combined with one another. The present application is described in detail below with reference to the drawings and the embodiments.
The conventional outdoor cabinet employs a sealing strip to wrap a flange for sealing. In order to ensure the sealing effect of the outdoor cabinet, it is necessary to ensure the roughness of the inside and outside of the flange during processing and manufacturing. However, welding spot and welding slag may inevitably appear at the surface of the flange after welding, and at this time, it is necessary to carefully polish the surface of the flange to ensure the roughness of the surface of the flange. But the space at the inner side of the flange is limited, and the polishing is very difficult. If the flanging is not polished well, the sealing strip may not be tightly clamped in the flange, resulting in water backflow and water leakage from the inside of the sealing strip. In addition, a transitional arc weldment that connects a vertical flange and a horizontal flange is easy to be deformed by a force during welding, so it is necessary to strictly control the welding process to ensure flatness and surface roughness requirements of the arc weldment; otherwise, there is a clearance between the flange and the sealing strip after the sealing strip is clamped, leading to water leakage. In view of the above problems, the manufacturers have spent a lot of manpower and material resources to deal with the machining process, which greatly increases the processing and manufacturing costs.
With reference to
In the embodiment, the flange drainage gap 21 is provided at a bottom of the flange structure 20, and the sealing structure 30 is sleeved on the flange structure 20. The flange drainage gap 21 of the flange structure 20 positionally corresponds to the auxiliary drainage gap 32 of the sealing structure 30. In rainy days, under the continuous impact of rainwater, some of the rainwater may leak into the groove 31 of the sealing structure 30. The rainwater flows along the flange structure 20 to a bottom of the groove 31. After reaching the bottom, the rainwater can be discharged through the flange drainage gap 21 and auxiliary drainage gap 32. The outflow path of the rainwater is shown as a curve with an arrow in
In the above embodiment, the flange structure 20 is arranged on the cabinet body 10, and the sealing structure 30 is arranged on the cabinet door. It should be noted that alternatively, the flange structure 20 may be arranged on the cabinet door, while the sealing structure 30 being arranged on the cabinet body 10, in this case, when the cabinet door is closed, the flange structure 20 is clamped in the groove 31 to realize sealing of the outdoor cabinet.
In an embodiment of the present application, the sealing structure 30 is a sealing strip.
With reference to
In the embodiment, the first side plate 311 is fitted to a surface of the flange structure 20 close to the cabinet body 10, and the second side plate 312 is fitted to another surface of the flange structure 20 away from the cabinet body 10. The auxiliary drainage gap 32 is formed at the first side plate 311. The rainwater that leaks into the groove 31 flows along the flange structure 20 to the bottom of the groove 31, and after reaching the bottom, the rainwater passes through the flange drainage gap 21 and the auxiliary drainage gap 32 in sequence to be discharged. The second side plate 312 abuts against the flange structure 20 to realize the sealing of the outdoor cabinet.
As shown in
In the embodiment, the flange drainage gaps 21 are formed at the bottom of the flange structure 20. The first side of the flange structure 20 corresponds to a left side of the cabinet body 10, and the second side of the flange structure 20 corresponds to a right side of the cabinet body 10. At least one flange drainage gap 21 is formed on each of the first side and the second side of the flange structure 20, and a left end and a right end of the bottom of the flange structure 20 are each provided with the flange drainage gap 21. The auxiliary drainage gaps 32 are provided in one-to-one correspondence with the flange drainage gaps 21. In this way, corresponding positions of the sealing structure 30 are provided with the auxiliary drainage gaps 32, the water that leaks into the sealing structure 30 can be discharged through the flange drainage gaps 21 and the auxiliary drainage gaps 32 formed at the left end and the right end of the bottom of the cabinet body 10, thus the drainage is faster and the sealing effect is better.
As shown in
In the embodiment, the first drainage gap 211 is formed at the vertical flange 23, the second drainage gap 212 is formed at the horizontal flange 24, the first drainage gap 211 corresponds to the third drainage gap 321 positionally, the second drainage gap 212 corresponds to the fourth drainage gap 322 positionally, and the vertical flange 23 is connected to the horizontal flange 24 through the transition arc structure 22. Since the first drainage gap 211 is located above the second drainage gap 212, most of the water leaking into the sealing structure 30 from top to bottom first flows out through the first drainage gap 211 and the third drainage gap 321, a small amount of the water that cannot be discharged in time flows along the transition arc structure 22 to the horizontal flange 24, and then flows out through the second drainage gap 212 and the fourth drainage gap 322. With the above arrangement, even if the roughness of the flange structure 20 and the flatness and the roughness of the transition arc structure 22 do not meet the requirements, the water that leaks into the sealing structure 30 can be discharged in time, so that the sealing and waterproof effect of the outdoor cabinet can be ensured, and the manufacturability can be greatly improved.
With reference to
In the embodiment, the third drainage gap 321 may be formed at the first side plate 311, or may be formed at the second side plate 312, and the fourth drainage gap 322 may be formed at the first side plate 311, or may be formed at the second side plate 312. As the first side plate 311 is fitted to the surface of the flange structure 20 close to the cabinet body 10, and the second side plate 312 is fitted to the surface of the flange structure 20 away from the cabinet body 10, therefore, on the premise that the sealing effect is ensured, the third drainage gap 321 and the fourth drainage gap 322 are preferably formed at the first side plate 311, to prevent the influence on a front appearance of the sealing structure 30.
With reference to
In the embodiment, the groove 31 of the sealing structure 30 includes the arc section 314 and can match the transition arc structure 22. With the above arrangement, it can be ensured that the sealing structure 30 is sleeved on the flange structure 20 more closely, to ensure the sealing effect.
With reference to
With the above arrangement, the water that leaks into the interior of the sealing structure 30 can be discharged more easily.
With reference to
With the above arrangement, it can be ensured that after the sealing structure 30 is sleeved on the flange structure 20, the sealing structure 30 is not prone to fall off or play relative to the flange structure 20, and thus has better structural stability.
From the above description, it can be seen that the embodiments of the present application achieve the following technical effects: the flange structure and the sealing structure are provided, the flange structure is provided with the flange drainage gap, and the sealing structure is provided with the auxiliary drainage gap. The water that leaks into the groove first flows along the groove to the bottom of the flange structure, after reaching the bottom, the water can be discharged through the flange drainage gap and the auxiliary drainage gap, to ensure that no water enters the interior of the outdoor cabinet, and water backflow and water leakage can be effectively avoided. Even if the flatness and the surface roughness of the flange structure do not meet the requirements, and there is a clearance between the sealing structure and the flange structure after the sealing structure is sleeved on the flange structure, the water entering the groove can still be discharged through the flange drainage gap and the auxiliary drainage gap. Therefore, the requirements for the flatness and the roughness of the flange structure can be effectively reduced, and thus the processing and manufacturing costs can be reduced.
