[0018] As Figure 1 , Figure 2 , Figure 3 described, an arrow lamp housing with good waterproof effect includes a base 1 and an arrow lamp body 2. A sunk groove is formed on the upper side of the base 1, and the arrow lamp body 2 is located in the sunk groove. A housing 4 is inserted in the sunk groove. The inner side of the housing 4 contacts the outer side of the arrow lamp body 2. C-shaped grooves 101 are formed on both the left and right sides of the sunk groove. Sealing plates 5 are slidably and sealedly connected in the C-shaped grooves 101 through sliders, chutes and gaskets. Sealing gaskets 8 that are hermetically attached to the housing 4 are adhesively attached to the sides of the sealing plates 5. The upper and lower ends of the sealing plates 5 and the housing 4 are respectively provided with matching inclined surfaces. The opposite sides of the sealing plates 5 are connected with a plurality of elastic components located on the left and right sides of the base 1.

[0019] During use, the staff installs the arrow lamp body 2 in the sunk groove through bolts. At the same time, the power cord of the arrow lamp body 2 is hermetically passed through the base 1 and connected to an external power source. After the arrow lamp body 2 is installed, the staff inserts the housing 4 into the sunk groove from top to bottom. During the insertion of the housing 4, the inclined surface at the lower end of the housing 4 fits with the inclined surface at the upper end of the sealing plate 5. At the same time, the housing 4 pushes the sealing plate 5 to move into the C-shaped groove 101. When the housing 4 is completely inserted into the sunk groove, the sealing plate 5 is always in contact with the outer side of the housing 4 under the action of the elastic components, preventing external water from flowing into the arrow lamp body 2 through the gap between the housing 4 and the base 1, improving the waterproof effect of the arrow lamp housing and ensuring the normal use of the arrow lamp body 2.
