[0038] The handle assembly 6 includes a handle 61 connected to the lamp tube assembly 1, and buckles 62 respectively disposed at both ends of the handle 61.

[0039] This utility model provides a portable explosion-proof searchlight, which achieves waterproofing by setting sealing rings between the components. It can be carried over the shoulder using a shoulder strap and buckle, making it convenient to carry. It can also be carried by hand.

[0040] Furthermore, as a preferred embodiment of this solution and not a limitation, the cover 41 is provided with a first mounting groove 411 for the first sealing ring 43 to be embedded in, and the faceplate assembly 4 further includes a first pressing ring 44 threadedly connected to the inner wall of the cover 41, the first pressing ring 44 pressing the lampshade 42 towards the first mounting groove 411. Waterproofing is achieved between the cover and the faceplate.

[0041] Furthermore, as a preferred embodiment of this solution and not a limitation, the lamp holder 31 is provided with a second mounting groove 311 for the second sealing ring 32 to be embedded in. The lamp head assembly 3 also includes a collar 33 sleeved on the lamp holder 31. When the cover 41 is threadedly connected to the lamp holder 31, the collar 33 presses against the cover 41 to limit the distance the lamp holder 31 can enter the cover 41, thereby maintaining a gap between the lamp holder 31 and the first pressing ring 44. This prevents the first pressing ring from pressing against the lamp cup, which would cause pressure on the lamp plate.

[0042] Furthermore, as a preferred embodiment of this solution and not a limitation, the lamp holder 31 is provided with heat dissipation fins 312 spaced apart along its axial direction on its outer periphery. This facilitates the transfer of heat to the heat dissipation fins through the heat sink.

[0043] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the light source assembly 5 includes a heat sink 51, a lamp plate 52 disposed on the heat sink 51, lamp beads 53 disposed on the lamp plate 52, and a lamp cup 54 disposed corresponding to the lamp beads 53.

[0044] Furthermore, as a preferred embodiment of this solution and not a limitation, the lamp holder assembly 3 further includes a first mounting platform 34 and a second mounting platform 35 disposed within the lamp holder 31, a second pressing ring 36 threadedly engaged with the lamp holder 31 to press the heat sink 51 against the first mounting platform 34, and a third pressing ring 37 threadedly engaged with the lamp holder 31 to press the lamp cup 54 against the second mounting platform 35. The installation method is simple.

[0045] Furthermore, as a preferred embodiment of this solution and not a limitation, the outer periphery of the cylinder 11 is provided with a third mounting groove 111 for the two third sealing rings 12 to be correspondingly embedded and spaced apart.

[0046] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the outer periphery of the cylinder 11 is provided with a fourth mounting groove 112 for the fourth sealing ring 22 to be embedded.

[0047] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the lamp tube assembly 1 includes a tube cover 13 disposed at the bottom opening of the tube body 11, and a fifth sealing ring 14 is provided between the bottom opening edge of the tube body 11 and the tube cover 13.

[0048] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the fifth sealing ring 14 has a square cross-section and simultaneously presses against the rear cover 21, the bottom of the cylinder 11, and the cylinder cover 13.

[0049] Furthermore, as a preferred embodiment of this solution and not a limitation, the rear cover is provided with a top pressing member 15, which presses against the cylinder cover.

[0050] Furthermore, as a preferred embodiment of this solution and not a limitation, the back cover 21 is hollowed out to create a hollow space 27 for installing the switch cap 23, indicator light 24, power display component 25, and charging port 26. The back cover is integrally formed of metal, hollowed out from a single piece of metal. The switch cap is inverted and pressed into the central circular hole of the back cover, and then secured with screws using machined hardware conforming to the inverted shape of the switch. Other holes protruding above the bottom surface are also hollowed out, allowing for the assembly of the indicator light and charging port, followed by sealing with AB glue. The power display component is encased in a transparent, injection-molded PC fire-retardant material, and then sealed with AB glue inside the back cover. This achieves complete sealing, reaching an IP66 / IP685m 1h protection rating. Typically, other back covers have a flat bottom surface, which is a key innovation.

[0051] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
