[0026] Figure 1 is the front view of the floodlight in the present utility model; Figure 2 is Figure 1 the sectional view taken along the line A - A in Figure 3 is the front perspective view of the floodlight in the present utility model; Figure 4 is the rear perspective view of the floodlight in the present utility model; Figure 5 is Figure 4 the enlarged view at B in Figures 1 to 5 as shown, showing a preferred embodiment, showing a floodlight, including a front cover 1, a rear cover 2, an explosion - proof glass 3, a light source 4, a bracket 5, a pin shaft 6, a connection seat 7, a first tooth block 8 and a second tooth block. The front cover 1 and the rear cover 2 are detachably connected, and an installation chamber is formed between the front cover 1 and the rear cover 2. The explosion - proof glass 3 is arranged in the front cover 1, and the light source 4 is arranged in the installation chamber. The light source 4 faces the explosion - proof glass 3. Two connection seats 7 are arranged on both sides of the rear cover 2. Both ends of the bracket 5 are connected to the connection seats 7 through two pin shafts 6. A plurality of first tooth blocks 8 are arranged on the side of the connection seat 7 close to the bracket 5, and a plurality of second tooth blocks are arranged on the side of the bracket 5 close to the connection seat 7. The first tooth blocks 8 cooperate with the second tooth blocks. In this embodiment, a housing 9 of the floodlight is formed between the front cover 1 and the rear cover 2. See Figure 5As shown, the first tooth block 8 is integrally formed with the connecting seat 7, and the connecting seat 7 is provided with a hole for installing the pin shaft 6. The bracket 5 is connected to the connecting seat 7 through the pin shaft 6, facilitating the relative rotation between the bracket 5 and the connecting seat 7. And through the mutual cooperation between the first tooth block 8 and the second tooth block, the relative fixation between the bracket 5 and the connecting seat 7 is facilitated. When the housing 9 is rotated, the first tooth block 8 and the second tooth block move relative to each other, causing the second tooth block to enter between two adjacent first tooth blocks 8, thereby realizing the adjustment of the angle of the housing 9 and further realizing the adjustment of the irradiation angle of the light source 4.

[0027] 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 snap connections to achieve disassembly between the two.

[0028] Among them, the bracket 5 is integrally arranged in a "П" shape, facilitating connection with the rear cover 2.

[0029] Furthermore, as a preferred embodiment, several first tooth blocks 8 are annularly distributed, and several second tooth blocks are annularly distributed. The first tooth block 8 and the second tooth block in this embodiment both have a certain elasticity. When the housing 9 is rotated, the second tooth block will squeeze the first tooth block 8, and the first tooth block 8 and the second tooth block will produce a certain deformation, facilitating the second tooth block to enter between two adjacent first tooth blocks 8. When no force is applied to the housing 9, two adjacent first tooth blocks 8 will clamp the second tooth block, making the housing 9 and the bracket 5 relatively fixed and realizing the fixation of the angle of the housing 9.

[0030] Furthermore, as a preferred embodiment, the light source 4 is connected to the rear cover 2 through the connecting member 10. Among them, see Figure 2 As shown, the light source 4 includes a circuit board and LED lamp beads arranged on the circuit board. The circuit board is connected to the rear cover 2 through the connecting member 10 (bolt).

[0031] Furthermore, as a preferred embodiment, the explosion-proof glass 3 is arranged in the front cover 1 and abuts against the rear cover 2. A sealing ring 11 is provided between the explosion-proof glass 3 and the front cover 1. See Figure 2 As shown, a card slot is provided on one side of the front cover 1 close to the rear cover 2, and the explosion-proof glass 3 is arranged in the card slot. A slot cooperating with the explosion-proof glass 3 is also provided on the rear cover 2. Among them, the sealing ring 11 is located on the side of the explosion-proof glass 3 close to the front cover 1 for sealing between the explosion-proof glass 3 and the front cover 1 to prevent water from entering the housing 9.

[0032] Furthermore, as a preferred embodiment, a sealant 12 is filled between the explosion-proof glass 3 and the rear cover 2. The sealant 12 is used to achieve a sealed connection between the rear cover 2 and the explosion-proof glass 3, preventing water from entering the light source 4 and realizing the protection of the light source 4.

[0033] Further, as a preferred embodiment, a plurality of heat dissipation fins 13 are provided on the rear cover 2. Among them, the heat dissipation fins 13 are integrally connected to the rear cover 2, which can conduct the heat inside the housing 9 to achieve the effect of heat dissipation, avoid the temperature inside the housing 9 from being too high, and protect the light source 4.

[0034] Further, as a preferred embodiment, it further includes a junction box 14. The junction box 14 is provided on the rear cover 2. A terminal post 15 is provided inside the junction box 14, and a wiring hole is provided on the terminal post 15. Among them, an end cover 16 is provided on the junction box 14, and the end cover 16 is detachably connected to the junction box 14. Refer to Figure 4 As shown, the end cover 16 and the junction box 14 are connected by bolts. A battery can be provided inside the junction box 14. The wire passes through the terminal post 15 and connects the circuit board of the light source 4 and the battery, which is convenient for supplying power to the light source 4, and the battery can be connected to the external mains power for charging the battery.

[0035] In this embodiment, a plurality of connection holes 17 are provided on the bracket 5, which can cooperate with bolts or screws to connect and fix the bracket 5 to an external structural member or the ground.

[0036] Among them, a power switch can be provided on the junction box 14, which is electrically connected to the battery to control the battery to supply power to or cut off power from the light source 4.

[0037] During use, first connect and fix the bracket 5 to an external structural member or the ground, and then rotate the housing 9. At this time, the second tooth block moves between a plurality of 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. Under 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.

[0038] The above are only the preferred embodiments of the present invention, and do not limit the implementation manners and protection scope of the present invention. For those skilled in the art, it should be realized that all equivalent replacements and obvious changes made by using the description and illustrations of the present invention should be included in the protection scope of the present invention.
