Description

Technical Field

[0001] This utility model relates to the field of electrical distribution box technology, and in particular to a waterproof cabinet door structure for an electrical distribution box. Background Technology

[0002] The distribution box employs a waterproof structure to prevent rainwater from entering and causing short circuits in the internal components. It typically uses a sealing gasket to seal the door and body of the box. This gasket is glued to the box interior, creating a seal when the door and gasket come into contact. However, over time, the gasket ages and needs replacement. Removing the gasket and cleaning the glue can be difficult due to the limited space inside the box, potentially leading to glue residue and compromising the sealing effect. Utility Model Content

[0003] The purpose of this utility model is to solve the shortcomings of the existing technology, such as limited space during operation leading to obstruction, difficulty in completely removing glue, easy glue residue, and thus affecting the sealing effect of the bonding, and proposes a waterproof cabinet door structure for electrical distribution boxes.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a waterproof cabinet door structure for a power distribution box, including a connecting frame, on which a sealing gasket is adhered. The sealing gasket has a rectangular frame structure and abuts against the box body and the box door. Multiple L-shaped blocks are fixedly connected to the box body, and the connecting frame abuts against the two inner walls of the L-shaped blocks. The L-shaped blocks are provided with an anti-displacement structure for the connecting frame.

[0006] Preferably, the box body is provided with drainage holes.

[0007] Preferably, the inner diameter of the upper end of the drain hole is larger than the inner diameter of the lower end.

[0008] Preferably, the anti-displacement structure includes a rotating shaft, which is rotatably connected to the L-shaped block via a bearing. An abutment block is fixedly connected to the rotating shaft, and the abutment block abuts against the connecting frame.

[0009] Preferably, the bearing is a thrust ball bearing.

[0010] Preferably, a support block is fixedly connected to the connecting frame, and the support block supports the abutment block.

[0011] Preferably, a magnet is fixedly connected to the support block, the magnet is opposite to the support block, and the support block is made of iron.

[0012] Preferably, the support block is provided with an anti-rust coating.

[0013] The waterproof cabinet door structure of the power distribution box proposed in this utility model has the following advantages: by removing the abutment frame from the box body, tearing off the sealing gasket on the abutment frame, cleaning up the residual glue, and reapplying glue to fix the new sealing gasket, the residual glue caused by the small operating space is avoided, which is conducive to the sealing effect of the sealing gasket.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1: Refer to Figure 1-5 A waterproof cabinet door structure for a power distribution box includes a connecting frame 3, with a sealing gasket 4 adhered to the connecting frame 3. The sealing gasket 4 has a rectangular frame structure and abuts against the cabinet body 1 and the cabinet door 2. Multiple L-shaped blocks 5 are fixedly connected to the cabinet body 1, and the connecting frame 3 abuts against the two inner walls of the L-shaped blocks 5. When the cabinet door 2 is closed, the cabinet door 2 abuts against the sealing gasket 4 to create a seal.

[0022] The L-shaped block 5 is equipped with an anti-displacement structure for the connecting frame 3. The anti-displacement structure includes a rotating shaft 9, which is rotatably connected to the L-shaped block 5 via a thrust ball bearing. An abutment block 6 is fixedly connected to the rotating shaft 9, and the abutment block 6 abuts against the connecting frame 3. By rotating the abutment block 6, the limiting fixation of the connecting frame 3 by the abutment block 6 will be released, thereby making it easy to remove the abutment frame 3 from the housing 1. The sealing gasket 4 on the abutment frame 3 can be peeled off, the residual glue can be cleaned, and new glue can be applied to fix the new sealing gasket 4. This avoids glue residue due to insufficient operating space and is beneficial to the bonding and sealing effect of the sealing gasket 4.

[0023] The housing 1 is provided with a drain hole 10, which facilitates the drainage of water flowing in from the gap between the housing 1 and the door 2. The inner diameter of the upper end of the drain hole 10 is larger than the inner diameter of the lower end, which helps to prevent dust from entering.

[0024] Example 2: Refer to Figure 5 As another preferred embodiment of the present invention, based on embodiment 1, a support block 7 is fixedly connected to the connecting frame 3. The support block 7 supports the abutment block 6 so as to support the abutment block 6 and ensure the abutment and limiting effect of the abutment block 6 on the connecting frame 3.

[0025] Example 3: Reference Figure 5 In another preferred embodiment of this utility model, based on embodiment 2, a magnet 8 is fixedly connected to the support block 7, with the magnet 8 facing the support block 7, which is made of iron. A rust-proof coating is provided on the support block 7, which is formed by the curing of rust-proof paint. The attraction between the magnet 8 and the support block 7 serves to limit the position of the abutment block 6, preventing the abutment block 6 from detaching from the connecting frame 3 during sealing.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
