[0032] The utility model will be illustrated in further detail below in combination with specific embodiments.

[0033] In the description of the utility model, it is understood that the directions or positional relationships indicated by the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" and the like are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as limiting the utility model in that the indicated devices or elements must have a particular orientation, be constructed and operated in a particular orientation.

[0034] As shown in Figures 1-4 , Figure 8 , a waterproof emergency tubular fluorescent lamp cover 21 comprises: a cover body with a mounting hole 1 in which an optical lens 24 is detachably mounted, a sealing ring 2 is mounted between the optical lens 24 and the cover body, and a ring-shaped mounting groove 3 for the sealing ring 2 is formed in the cover body by upwardly and inwardly recessing the position corresponding to the mounting position of the sealing ring 2. As shown in Figure 7 , the mounting hole 1 of the cover body extends upwardly and inwardly to form a first ring 6-shaped step 4, and the edge of the ring of the first ring 6-shaped step 4 extends downwardly to form a ring-shaped first lower boss 5, and the first ring 6-shaped step 4 and the first lower boss 5 form the mounting groove 3.

[0035] As shown in Figure 5 , Figure 6 , Figure 8 , the optical lens 24 comprises a first ring 6, a conical ring 7, a second ring 8 and a lens part 9 connected in sequence; the inner ring surface of the first ring 6 and the inner ring surface of the conical ring 7 are on the same conical surface; the lens part 9 completely covers the ring opening of the second ring 8, and the lens part 9 comprises a lens connecting part and an arc-shaped lens 11; in this embodiment, the optical lens 24 is detachable, and the optical lens 24 has different models; the only difference between the optical lenses 24 of different models is the shape of the lens 11, and the remaining parts are the same; when selecting the model, the customer can select the model of the optical lens 24 according to the required light shape; the edge of the second ring 8 extends oppositely to form a pair of clamping ears 10; the distance between the outer edges of the pair of clamping ears 10 is greater than the diameter of the inner circle of the first lower boss 5; and the diameter of the outer circle of the first ring 6 matches the diameter of the lower hole opening of the mounting hole 1.

[0036] As shown in Figure 4As shown, the inner wall of the first lower boss 5 is concave outward and has a first arc-shaped groove 12 and a second arc-shaped groove 13 with the same shape as the clasp 10. The first arc-shaped groove 12 and the second arc-shaped groove 13 are used for a pair of clasps 10 to pass through along the axial direction of the optical lens 24. The first lower boss 5 forms a first retaining ring plate 14 located on the side of the first arc-shaped groove 12 by cutting an arc-shaped notch that communicates with the first arc-shaped groove 12. The first lower boss 5 forms a second retaining ring plate 15 located on the side of the second arc-shaped groove 13 by cutting an arc-shaped notch that communicates with the second arc-shaped groove 13. The first retaining ring plate 14 and the second retaining ring plate 15 can secure the optical lens 24 in the mounting hole 1. The first lower boss 5 is cut with an annular conical surface to avoid misalignment of the optical lens 24.

[0037] like Figure 1 As shown, a ring platform 16 extends upward from the circumferential edge of the cover body. The ring platform 16 continues to extend inward to form multiple equal-width retaining plates 18. Each retaining plate 18 extends downward to the same side as a baffle 19. The retaining plates 18 and baffles 19 together form a retaining plate 17. The bottom surfaces of the first ring 6 and the conical ring 7 are both provided with upward-facing insertion holes 20 that do not completely penetrate the first ring 6 and the conical ring 7 (e.g., ...). Figure 6 (As shown).

[0038] This utility model also provides an emergency light, including the aforementioned waterproof emergency downlight cover 21.

[0039] In this utility model, the process of installing the optical lens 24 on the faceplate 21 is as follows: The optical lens installation tool 23 (such as...) is used to install the optical lens 24 onto the faceplate 21. Figure 11 As shown, the optical lens 24 is inserted into the insertion hole 20 of the optical lens 24. The optical lens 24 is picked up with the optical lens mounting tool 23. The pair of clasps 10 of the optical lens 24 are aligned with the first arc groove 12 and the second arc groove 13 respectively. Then it is inserted into the mounting hole 1. When the first ring 6 of the optical lens 24 abuts against the first lower protrusion 5 of the faceplate 21, that is, when the optical lens 24 is inserted to the maximum depth in the mounting hole 1, the lens is rotated with the optical lens mounting tool 23 to secure the optical lens 24 to the first retaining ring plate 14 and the second retaining ring plate 15.

[0040] In this embodiment, the mounting groove 3 is concave upwards. After the optical lens 24 is installed on the faceplate 21, when pressurized water is sprayed onto the faceplate 21 (for water with no pressure or very low pressure, the sealing ring 2 can effectively block the water outside the faceplate 21), the water flow path is as follows under the seal of the sealing ring 2: Figure 9 As shown, for water to flow into the interior of the emergency downlight, it needs to pass over the inner surface 22 of the mounting groove 3. This means the mounting groove 3 also provides some obstruction for the water. In the prior art, the mounting groove 3 is located on the optical lens 24, and the water flow path is as follows... Figure 10The water under pressure is easy to flow into the inside of the emergency tube lamp; the design of the mounting groove 3 greatly improves the waterproof capability of the face cover 21.
