[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figures 1 to 4 As shown, in this embodiment, an explosion-proof LED lamp includes an explosion-proof lamp body 1 and a mounting bracket 3. A plug 6 is provided at the rear end of the explosion-proof lamp body 1. The outer surface of the explosion-proof lamp body 1 is provided with a protective frame 2 and is fixedly connected to the protective frame 2. The protective frame 2 is suspended on the mounting bracket 3. The protective frame 2 is rotatably connected to the mounting bracket 3. The mounting bracket 3 is provided with an angle adjustment mechanism acting on the explosion-proof lamp body 1. The angle adjustment mechanism is composed of a fixed rod 9, a movable rod 11, a fixed plate 12, a spring 13 and a locking rod 14.

[0021] Among them, the mounting frame 3 is composed of a triangular plate 4 and a connecting rod 5. The two triangular plates 4 are symmetrically distributed on both sides of the explosion-proof lamp body 1. The two sides of the protective frame 2 are rotatably connected to the two triangular plates 4 through the rotating shaft 8. Three connecting rods 5 are fixedly connected between the two triangular plates 4, and the three connecting rods 5 are respectively distributed at the three corners of the triangular plate 4.

[0022] The triangular structure has good stability, which can ensure that the mounting frame 3 remains stable after being placed.

[0023] Among them, the fixed rod 9 is fixedly connected to the axial end of a rotating shaft 8 away from the explosion-proof lamp body 1, and a movable groove 10 is opened at the axial center position of the fixed rod 9. A movable rod 11 is slidably inserted in the movable groove 10, and the protruding end of the movable rod 11 is fixedly connected to a fixed plate 12. A spring 13 is fixedly connected between the fixed plate 12 and the rotating shaft 8. The spring 13 is wound around the outer surface of the fixed rod 9. Locking rods 14 are respectively fixedly connected on both sides of the fixed plate 12, and a handle 7 is fixedly connected to the side of the fixed plate 12 away from the movable rod 11.

[0024] A limiting plate 17 is fixedly connected to the side wall of the movable rod 11 , and a limiting groove 18 adapted to the limiting plate 17 is defined in the movable groove 10 .

[0025] The limiting plate 17 and the limiting groove 18 can ensure that the movable rod 11 cannot rotate in the movable groove 10.

[0026] The length of the locking rod 14 is greater than the length of the movable rod 11 .

[0027] With this arrangement, before the movable rod 11 touches the bottom in the movable groove 10 , the locking rod 14 will first press the triangular plate 4 .

[0028] Among them, the locking rod 14 is fixedly connected to the end close to the triangular plate 4 with a rubber pad 15, and the side wall of the triangular plate 4 is provided with a frosted layer 16, which is an annular structure and is located at an extension position of the movement trajectory of the rubber pad 15.

[0029] The friction between the locking rod 14 and the triangular plate 4 can be increased by providing the rubber pad 15 and the frosted layer 16 .

[0030] This utility model provides an explosion-proof LED lamp, the specific working principle is as follows:

[0031] When in use, the mounting bracket 3 is placed on the ground, and the explosion-proof lamp body 1 is powered on through the plug 6. When the illumination angle of the explosion-proof lamp body 1 needs to be adjusted, the handle 7 is held and pulled outward to separate the rubber pad 15 from the frosted layer 16 on the triangular plate 4. At this time, the spring 13 will be further stretched (when the handle 7 is not pulled, the spring 13 is also in a stretched state). Then, the handle 7 is turned to drive the movable rod 11 to rotate. Due to the presence of the limit plate 17 and the limit slot 18, the fixed rod 9 will rotate synchronously with the movable rod 11. Rotate, thereby driving the rotating shaft 8 to rotate, and the rotation of the rotating shaft 8 can control the rotation of the explosion-proof lamp body 1. When the explosion-proof lamp body 1 is adjusted to a suitable tilt angle, release the handle 7. Under the pull of the spring 13 to restore the deformation, the rubber pad 15 will press on the frosted layer 16 of the triangular plate 4, thereby fixing the movable rod 11, and then fixing the explosion-proof lamp body 1 in a suitable position. This structural design can quickly complete the angle adjustment of the explosion-proof lamp body 1, and can quickly fix the explosion-proof lamp body 1 after the angle adjustment is completed.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
