For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Figure 1 is a front view of the floodlight of this utility model; Figure 2 is a sectional view along line AA in Figure 1; Figure 3 is a front perspective view of the floodlight of this utility model; Figure 4 is a rear perspective view of the floodlight of this utility model; Figure 5 is an enlarged view of point B in Figure 4. Referring to Figures 1 to 5, a preferred embodiment is shown, illustrating a floodlight including a front cover 1, a rear cover 2, an explosion-proof glass 3, a light source 4, a bracket 5, pins 6, connecting seats 7, first toothed blocks 8, and second toothed blocks. The front cover 1 and the rear cover 2 are detachably connected, forming an installation chamber between them. The explosion-proof glass 3 is disposed inside the front cover 1, and the light source 4 is disposed inside the installation chamber, facing the explosion-proof glass 3. Two connecting seats 7 are provided on both sides of the rear cover 2. The two ends of the bracket 5 are connected to the connecting seats 7 via two pins 6. Several first toothed blocks 8 are provided on the side of the connecting seat 7 near the bracket 5, and several second toothed blocks are provided on the side of the bracket 5 near the connecting seat 7. The first toothed blocks 8 cooperate with the second toothed blocks. In this embodiment, a floodlight housing 9 is formed between the front cover 1 and the rear cover 2. As shown in Figure 5, the first toothed block 8 and the connecting seat 7 are integrally formed, and the connecting seat 7 is provided with a hole for installing the pin 6. The bracket 5 is connected to the connecting seat 7 through the pin 6, which facilitates relative rotation between the bracket 5 and the connecting seat 7. The relative fixation between the bracket 5 and the connecting seat 7 is facilitated by the mutual cooperation of the first toothed block 8 and the second toothed block. When the housing 9 is rotated, the first toothed block 8 and the second toothed block move relative to each other, so that the second toothed block enters between two adjacent first toothed blocks 8, thereby realizing the adjustment of the angle of the housing 9, and further realizing the adjustment of the illumination angle of the light source 4.

[0028] Among them, the explosion-proof glass 3 has high strength and can protect the light source 4 in the installation room. The front cover 1 and the rear cover 2 can be connected by bolts or clips to achieve disassembly between the two.

[0029] The bracket 5 is shaped like a "П" to facilitate connection with the back cover 2.

[0030] Furthermore, as a preferred embodiment, a plurality of first toothed blocks 8 are arranged in a ring, and a plurality of second toothed blocks are arranged in a ring. In this embodiment, both the first toothed blocks 8 and the second toothed blocks have a certain degree of elasticity. When the housing 9 is rotated, the second toothed blocks will squeeze the first toothed blocks 8, and the first toothed blocks 8 and the second toothed blocks will undergo a certain deformation, which facilitates the second toothed blocks to enter into the two adjacent first toothed blocks 8. When no force is applied to the housing 9, the two adjacent first toothed blocks 8 will clamp the second toothed blocks, so that the housing 9 and the bracket 5 are relatively fixed, thereby fixing the angle of the housing 9.

[0031] Furthermore, as a preferred embodiment, the light source 4 is connected to the back cover 2 via the connector 10. As shown in Figure 2, the light source 4 includes a circuit board and LED beads disposed on the circuit board, and the circuit board is connected to the back cover 2 via the connector 10 (bolt).

[0032] Furthermore, as a preferred embodiment, the explosion-proof glass 3 is disposed inside the front cover 1 and abuts against the rear cover 2, with a sealing ring 11 provided between the explosion-proof glass 3 and the front cover 1. Referring to Figure 2, a slot is provided on the side of the front cover 1 near the rear cover 2, and the explosion-proof glass 3 is disposed in the slot. A groove for cooperating with the explosion-proof glass 3 is also provided on the rear cover 2. The sealing ring 11 is located on the side of the explosion-proof glass 3 near the front cover 1 and is used to seal between the explosion-proof glass 3 and the front cover 1 to prevent water from entering the housing 9.

[0033] Furthermore, as a preferred embodiment, sealant 12 is filled between the explosion-proof glass 3 and the back cover 2. The sealant 12 achieves a sealed connection between the back cover 2 and the explosion-proof glass 3, preventing water from entering the light source 4 and thus protecting the light source 4.

[0034] Furthermore, as a preferred embodiment, the rear cover 2 is provided with a plurality of heat dissipation fins 13. The heat dissipation fins 13 are integrally connected to the rear cover 2, which can conduct heat out of the inside of the housing 9, achieve the effect of heat dissipation, prevent the internal temperature of the housing 9 from becoming too high, and protect the light source 4.

[0035] Furthermore, as a preferred embodiment, it also includes a junction box 14, which is provided on the rear cover 2. The junction box 14 contains terminal blocks 15, each with a wiring hole. An end cap 16 is provided on the junction box 14 and is detachably connected to it. Referring to Figure 4, the end cap 16 is bolted to the junction box 14. A battery can be housed inside the junction box 14. Wires pass through the terminal blocks 15 and connect to the circuit board of the light source 4 and the battery, facilitating power supply to the light source 4. The battery can also be connected to external AC power for charging.

[0036] In this embodiment, the bracket 5 is provided with several connection holes 17, which can be used with bolts or screws to connect and fix the bracket 5 to external structural components or the ground.

[0037] A power switch may be provided on the junction box 14 for electrical connection with the battery to control the battery to supply power to or cut off the power to the light source 4.

[0038] When in use, first connect and fix the bracket 5 to the external structural components or the ground. Then, by rotating the housing 9, the second tooth block moves between several first tooth blocks 8 and enters between the corresponding two first tooth blocks 8 to adjust the angle of the housing 9. Then, release the housing 9. With the cooperation of the first tooth block 8 and the second tooth block, the angle of the housing 9 is fixed. Then, the battery supplies power to the light source 4, and the light source 4 is turned on to provide illumination.

[0039] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
