During installation, the waterproof ring is usually placed at the opening of the power box, fitting tightly with the power box cover to form an effective waterproof barrier; the application range of the power box waterproof ring is very wide, including but not limited to various electronic equipment, communication equipment, medical equipment, security equipment, etc. In humid or rainy environments, the role of the power box waterproof ring is particularly important. It can ensure that the circuit boards and electronic components inside the power box can still work normally in harsh environments, thereby extending the service life and stability of the equipment;

[0003] Among them, the "waterproof sealing ring for high-voltage box" disclosed in the application number "CN202022917806.0" is also an increasingly mature technology. The waterproof sealing ring for the high-voltage box adopts bolt patches and side pads. The bolt patches increase the friction at the connection between the bolts and the high-voltage box to avoid the displacement or shaking of the rubber pad body during the connection and locking process of the bolts, thereby ensuring the waterproof effect of the high-voltage box during use. However, the waterproof ring still has the following defects: Since the waterproof ring is placed inside the battery box, it has a certain waterproof function, but in the above-mentioned public patent, when installing the waterproof ring, additional bolts are required to fix it, which makes the installation process of the waterproof ring cumbersome. In addition, over a long period of time, the rust of the bolts causes the waterproof ring to be insufficiently sealed, affecting the waterproof effect. Utility Model Content

In addition, over a long period of time, the bolts rust and cause insufficient sealing of the waterproof ring, thereby affecting the waterproof effect.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a waterproof ring structure for a power box, comprising a waterproof ring body, one side of the waterproof ring body is connected to a side adhesive ring, the outer wall of the waterproof ring body is connected to a side adhesive convex strip, and the outer corner of the side adhesive ring is connected to a limiting bent strip.

[0006] In order to improve the waterproof performance, as a preferred waterproof ring structure for a power box of the utility model, the waterproof ring body and the side ring are both made of rubber material, and the inner ring sizes of the waterproof ring body and the side ring are the same.

[0007] In order to facilitate proper installation, as a preferred waterproof ring structure for a power box of the utility model, both ends of the side-attached convex strip are arc-shaped structures, and the curvature of the limiting bend strip is adapted to the curvature of the bend angle of the side-attached ring.

[0008] In order to increase the friction force, as a preferred waterproof ring structure for a power box of the utility model, the back of the waterproof ring body is connected to an attachment pad, and the attachment pad is made of rubber.

[0009] In order to facilitate installation, as a preferred waterproof ring structure for a power box of the utility model, central adsorption grooves are opened on the upper and lower ends of the back side of the attachment pad, and side adsorption grooves are opened on both side ends of the back side of the attachment pad.

[0010] In order to ensure stable adsorption, as a preferred waterproof ring structure for a power box of the utility model, the cross-section of the central adsorption groove and the side adsorption groove is a T-shaped structure, and the larger opening is located on the surface of the attachment pad.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model places the attachment pad on the inner side of the battery box cover, and then when the battery box cover is closed, the side attachment ring contacts the inner side of the battery box, and at the same time, the side attachment convex strips on the surface of the side attachment ring are squeezed, so that the waterproof ring body and the side attachment ring are expanded, and then closely contact the inner side of the battery box. At the same time, the overall rubber structure improves the service life and waterproof efficiency of the waterproof ring; in addition, when the attachment pad is installed, the central adsorption groove and the side adsorption groove are used, so that the waterproof ring body is more stably attached to the inside of the battery box cover to avoid falling off.
