Description

Technical Field

[0001] This utility model relates to cabinet frames, specifically to a waterproof structure for the top hanging ring of the cabinet frame. Background Technology

[0002] The cabinet frame is the basic supporting structure of the cabinet. Depending on the type of cabinet and application scenario, it comes in various forms, such as frame cabinets, panel frame structures, metal frame structures, and modular frames. For easy movement, lifting rings are generally installed at the top of the cabinet frame. The installation methods for existing cabinet frame lifting rings are generally as follows: 1. The lifting ring connecting column is welded to the frame, passing through the top steel plate of the cabinet and directly welded to the internal supporting channel steel or frame. The supporting channel steel is U-shaped and distributed at the cabinet panel joints to enhance the overall structural strength and prevent top plate deformation during hoisting; 2. The lifting rings are prefabricated with a steel frame. During cabinet production, lifting rings are welded to the top of the basic steel frame (such as No. 10 channel steel), forming a unified whole with the cabinet after installation.

[0003] None of the above-mentioned hanging ring methods can meet outdoor waterproofing requirements. If the hanging ring bolts are tightened too much, the top cover may deform, creating a puddle. If they are tightened too little, there is a risk of it falling off. Utility Model Content

[0004] This invention can effectively solve the above problems, allowing the lifting rings to be tightened without causing deformation of the top cover or the formation of water puddles; it can effectively reduce the risk of water leakage after various outdoor cabinets are hoisted.

[0005] To solve the above-mentioned technical problems, the present invention provides a technical solution for a waterproof structure at the top hanging ring:

[0006] The cabinet includes a cabinet frame and hanging rings; a top cover is connected to the top of the cabinet frame, and a bottom plate is connected to the bottom; a column is connected inside the cabinet frame, and a top cover with an upwardly protruding upper cap is sealed directly above the column; a waterproof welded nut is connected to the inner side of the upper end of the column; the lower end of the hanging ring passes through the upper cap and is threadedly connected to the waterproof welded nut; a water outlet channel is provided between the waterproof welded nut and the column; a water outlet pipe is connected to the bottom of the column; a water outlet fitting is fitted onto the water outlet pipe; one end of the water outlet fitting is fitted onto the water outlet pipe, and the other end passes through the bottom plate and is located outside the cabinet frame.

[0007] A silicone sealing ring connects the lifting ring to the upper cover.

[0008] A sheet metal gasket connects the silicone sealing ring and the lifting ring.

[0009] The inner side of the silicone sealing ring is connected to a limiting sheet metal to prevent the silicone sealing ring from failing due to overtightening of the lifting ring.

[0010] The lower part of the upper cover is connected to a lower baffle; the upper end of the column is fitted onto the outside of the lower baffle.

[0011] An installation port for easy installation of water outlet pipe fittings is provided at the bottom of the column.

[0012] The inner wall of the column is coated with a rust-proof paint layer.

[0013] The technical effects that this utility model can achieve are:

[0014] 1. The present invention has an upwardly protruding upper cover that is sealed and connected directly above the column of the top cover. Therefore, when tightening the lifting ring, only the upper end surface of the upper cover will be deformed, and it will not easily affect the top cover itself.

[0015] 2. If water leaks between the cover and the hanging ring, this utility model can divert the leaked water to the outlet pipe end through the column, and discharge it from the cabinet frame through the outlet pipe fitting. The cabinet frame is still not easy to get water inside.

[0016] 3. A silicone sealing ring is installed between the lifting ring and the upper cover to further enhance the sealing performance. Attached Figure Description

[0021] Figure 4 yes Figure 2 Enlarged view of part B. Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] See Figures 1 to 4 .

[0024] A waterproof structure for a top hanging ring includes a cabinet frame 1 and a hanging ring 2. A top cover 3 is connected to the top of the cabinet frame 1, and a bottom plate 4 is connected to the bottom. A column 5 is connected inside the cabinet frame 1. A top cover 6 with an upward protrusion is sealed above the column 5 of the top cover 3. A waterproof welding nut 7 is connected to the inner side of the upper end of the column 5. Specifically, the waterproof welding nut 7 is welded to the column 5. A lower baffle 31 is connected to the lower part of the middle of the upper cover 6, and the upper end of the column 5 is fitted outside the lower baffle 31. The lower end of the hanging ring 2 passes through the upper cover 6 and is threadedly connected to the waterproof welding nut 7. By setting the upper cover 6, the force is mainly borne by the upper end surface of the upper cover 6 during the tightening process of the hanging ring 2. Therefore, only the upper end surface of the upper cover 6 will be deformed, and it is not easy to affect the top cover 3 itself.

[0025] In the specific connection between the lifting ring 2 and the upper cover 6, a silicone sealing ring 21 is connected between the lifting ring 2 and the upper cover 6, and a sheet metal gasket 22 is connected between the silicone sealing ring 21 and the lifting ring 2. The silicone sealing ring 21 can effectively improve the sealing performance between the lifting ring 2 and the upper cover 6. A limiting sheet metal 23 is connected to the inner side of the silicone sealing ring 21 to prevent the silicone sealing ring 21 from failing due to over-tightening of the lifting ring 2.

[0026] A water outlet channel 8 is provided between the waterproof welding nut 7 and the column 5; a water outlet pipe end 9 is connected to the bottom of the column 5, and a water outlet fitting 10 is fitted on the water outlet pipe end 9; one end of the water outlet fitting 10 is fitted on the water outlet pipe end 9, and the other end passes through the base plate 4 and is located outside the cabinet frame 1; preferably, the water outlet fitting 10 is a rubber hose, and an installation port 32 is provided at the bottom of the column 5 for easy installation of the water outlet fitting 10, and the inner wall of the column 5 is coated with an anti-rust paint layer.

[0027] When the seal between the lifting ring 2 and the upper cover 6 still has a problem (i.e., there is still water leakage), water will flow in from between the lifting ring 2 and the upper cover 6, then fall into the column 5 along the lower edge 31, pass through the water outlet channel 8 and flow along the column 5 to the water outlet pipe end 9, and finally the leaked water is discharged out of the cabinet frame 1 through the water outlet fitting 10, so that water is still not easy to enter the cabinet frame 1; and the inner wall of the column 5 is coated with an anti-rust paint layer, which can effectively prevent the inner wall of the column 5 from rusting, and through the above-mentioned diversion method, it can effectively ensure that water is not easy to enter the cabinet frame 1.
