[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] See Figures 1 to 4 As shown, an intrinsically safe explosion-proof marker light includes a strip-shaped light body 1, end caps 2 fixed to both ends of the strip-shaped light body, a light body structure 3 fixed to the top surface of the strip-shaped light body, and a marker plate 4 provided on the bottom surface of the strip-shaped light body. An n-shaped slot 5 is provided on the bottom surface of the strip-shaped light body, and the top surface of the marker plate is inserted into the n-shaped slot and fixed with screws. In this embodiment, the strip-shaped light body is a plastic or metal structural component, and the marker plate is an integrally formed acrylic plate with marking patterns. These are all existing technologies, simply applied in a simplified manner.

[0027] In this embodiment, the lamp body structure includes a power supply box 31, a drive circuit board 32, an input power line 33, a strip light source board 34, a sealing structure 35, and a round cover 36. The power supply box can withstand explosion pressure without deformation or cracking. It is a plastic or metal structural component, which can improve explosion-proof performance. The drive circuit board, the input power line, and the strip light source board are all conventional structures in the prior art, and are simply applied, so they are not described in detail.

[0028] Explosion-proof means that an internal explosion is allowed, but the explosion can be prevented from spreading to the external environment through power supply boxes, etc., thus achieving the explosion-proof effect. Intrinsically safe means preventing the generation of sparks or thermal effects that could ignite the energy source.

[0029] The power supply box includes a drive cavity 6 with an open front, and a wiring hole 7 on its side wall. During manufacturing, the power supply box is fixed to the top surface of the strip lamp body. It can be fixed by screws or integrally formed. The drive circuit board is fixed inside the drive cavity, and the input power line is connected to the drive circuit board. A sealing structure is located between the input power line and the wiring hole. The strip light source plate is fixed to the top wall of the n-shaped slot, and the drive circuit board is connected to the strip light source plate. A circular cover is located at the opening of the drive cavity. The light from the strip light source plate is emitted outward through the marking plate. The circular cover can be disassembled, which is beneficial for the inspection and maintenance of the drive circuit board, while the sealing structure improves the sealing of the connection between the input power line and the power supply box.

[0030] In this embodiment, the sealing structure includes a sealing ring 351, a sealing gasket 352, and a wire clamping nut 353. During assembly, the input power cable passes through the wire clamping nut, and the sealing ring and sealing gasket seal between the wire clamping nut and the through hole. A waterproof ring 8 is also provided at the opening between the round cover and the drive cavity. This improves the overall sealing and waterproof performance of the power supply box. The round cover is threadedly connected to the opening of the drive cavity.

[0031] This utility model has positive effects: The structure of this utility model is reasonable. The power box is fixed on the top surface of the strip light body, and the drive power board, input power line, etc. are placed in the power box. The power box can withstand the explosion pressure without deformation or cracking, which can improve the explosion-proof performance of the entire structure. In addition, the drive circuit board and the strip light source board are set separately, which is conducive to improving the safety and reliability of wiring. Furthermore, it works with the sign plate to ensure the effectiveness of the sign and has strong applicability.

[0032] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0033] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
