DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example

[0026] See Figures 1 to 4 As shown, a snap-on explosion-proof street lamp structure includes a lamp body 1 and a cavity cover 2, wherein the lamp body is provided with a concave cavity 3 with a top surface and a side opening, and the side opening of the concave cavity is provided with an end cover 4, and the lower part of the symmetrical side wall of the concave cavity is provided with a C-shaped card groove 5, and a heat sink 6 is provided in the concave cavity, and the symmetrical edges of the heat sink are integrally formed with a convex strip 7; in this embodiment, the lamp body is a conventional structure of the prior art, which can be a plastic structure or an aluminum structure, and its convex strip cooperates with the C-shaped card groove, and the two are connected by plug-in connection during assembly, and its radiator is smaller than the length of the concave cavity, and the width between the two convex strips is the same as the width between the two C-shaped card grooves, so that assembly connection can be achieved, and the length of the convex strip is the same as the length of the C-shaped card groove, which will not cause the radiator to shift or shake during assembly, thereby ensuring the effectiveness of the position of the fitting with the light source board and improving the heat dissipation effectiveness.

[0027] During assembly, the convex strip enters from the end of the C-shaped slot and pushes the heat sink into the concave cavity. The end cap is inserted into the side opening of the concave cavity to position the heat sink, and the bottom surface of the heat sink is attached to the bottom wall of the concave cavity. In addition, a light source cavity 8 is provided in the middle of the bottom surface of the lamp body, in which a light source board 9, a lens body 10 and a positioning frame edge 11 are fixed. During assembly, the light source board is fixed in the light source cavity by screws, the lens body is attached to the bottom surface of the light source board and is clamped and positioned by the positioning frame edge, and the positioning frame edge is snapped into the light source cavity. The cavity cover is fixed to the top opening of the concave cavity by screws. The light source board is a high-power light source board, and the heat generated by it is transferred to the heat sink through the top wall of the light source cavity for dissipation.

[0028] The above structure reduces the use of screws, improves the convenience of assembly, and ensures the smoothness and reliability of assembly. It is also conducive to the disassembly, assembly, replacement and maintenance operations of various components. The light source cavity is separated from the concave cavity, which is conducive to improving the explosion-proof performance and has strong applicability.

[0029] In this embodiment, a heat conducting sheet 12 is embedded between the top wall of the light source cavity and the bottom wall of the concave cavity; the light source board is attached to the bottom surface of the heat conducting sheet, and the heat sink is attached to the top surface of the heat conducting sheet. The heat conducting sheet is mainly used for heat transfer from the light source board and is mainly made of aluminum.

[0030] In this embodiment, a mounting handle 13 is fixed to the side of the lamp body via screws. An insertion cavity 14 is provided at the side opening of the recessed cavity, with snap-fit ​​holes 15 provided on the side walls. An insert block 16 is fixed to the side of the end cap, with snap-fit ​​bumps 17 provided on the side walls. During assembly, the insert block is inserted into the insertion cavity, and the snap-fit ​​bumps engage the snap-fit ​​holes to secure it. This improves the convenience and effectiveness of end cap connection and reduces the need for screws.

[0031] Furthermore, a sealing gasket is provided at the connection between the positioning frame edge and the light source cavity. The top surface of the lamp body is provided with a driving cavity 18. A driving power supply is fixed in the driving cavity for supplying power to the light source board.

[0032] The present invention has positive effects: the structure of the present invention is reasonably arranged, and a C-shaped slot is arranged at the lower part of the symmetrical side wall of the concave cavity. The radiator is limited in the C-shaped slot by inserting the convex strip and then positioned by the end cover, which can improve the assembly convenience and stability of the radiator. At the same time, the light source cavity is separated from the concave cavity, and the radiator can be disassembled and assembled separately, and the light source board, lens body and positioning frame edge can also be disassembled and assembled separately. Moreover, since there is an isolation layer between the light source cavity and the concave cavity, the light source and the heat dissipation are physically separated. While ensuring the heat dissipation effectiveness of the radiator, the high temperature of the radiator can be avoided from igniting explosives, which is beneficial to improving the explosion-proof performance and heat dissipation performance. In addition, each component is also convenient for replacement or maintenance operations, and has strong applicability.

[0033] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components described in the specification can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.

[0034] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. However, obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
