[0002] The existing grating screen is mainly composed of a light bar housing with a light bar installed and a power box with a power module installed. The profile is the integral structural part of the grating screen, which plays the role of overall support and accessory installation. The light bar housing and power box of the grating screen on the market are both provided with multiple openings, which are used for connecting wires to pass through. Since the grating screen will be used outdoors for some time, it is necessary to seal the openings. When sealing the openings, the prior art usually sets a waterproof rubber ring at the opening for waterproofing. During installation, the waterproof rubber ring needs to be aligned with the openings on the light bar housing and the power box at the same time, so that the waterproof rubber ring can play a corresponding waterproof role. However, since the waterproof rubber ring cannot be fixed, once the waterproof rubber ring is misaligned with the opening on the light bar housing or the power box, the waterproof rubber ring cannot play a waterproof role.
