[0027] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] As Figures 1-5 shown, a floodlight that is convenient for folding includes a bracket mechanism 1. The bracket mechanism 1 includes a U-shaped frame 11. A lamp mechanism 2 is arranged inside the U-shaped frame 11. A protection plate 3 is arranged at the rear side of the bracket mechanism 1. Limiting mechanisms 4 are arranged at both ends of the top between the bracket mechanism 1 and the protection plate 3. Movable seats two 5 are arranged at both ends of the bottom between the bracket mechanism 1 and the protection plate 3. Both ends of the bracket mechanism 1 and the protection plate 3 are respectively rotationally connected through the movable seats two 5;

[0029] Through grooves 12 are respectively drilled at both ends of the U-shaped frame 11, and ball grooves 13 are drilled at the middle positions of the through grooves 12;

[0030] The lamp mechanism 2 includes a lamp board 21. Adjusting rods 22 are respectively fixed at both ends of the lamp board 21. Extrusion nuts 24 are sleeved on the outer walls of the ends of the adjusting rods 22 far away from the lamp board 21. External thread teeth 25 are arranged on the outer walls of the adjusting rods 22 at one end of the extrusion nuts 24. Slide balls 23 are fixed at the ends of the adjusting rods 22 far away from the external thread teeth 25;

[0031] The limiting mechanism 4 includes a movable seat one 41 and a T-shaped block 46. A perforated base block 42 is rotationally connected to the movable seat one 41. A spring rod 43 is embedded inside the perforated base block 42. An L-shaped block 44 is fixed at the telescopic end of the spring rod 43. A T-shaped groove 45 is drilled at the inner top of the L-shaped block 44.

[0032] Specifically, the adjusting rods 22 are respectively connected to the through grooves 12, and the sliding balls 23 are respectively inserted into the ball grooves 13, so that the light board 21 can rotate. At the same time, the adjusting rods 22 in the through grooves 12 and the sliding balls 23 in the ball grooves 13 are raised and lowered to adjust the illumination height of the light board 21.

[0033] Specifically, the adjusting rod 22 is threadedly connected to the extrusion nut 24 through the external screw teeth 25, and the extrusion nut 24 is in contact with the outer side of the U-shaped frame 11 and its outer side wall, so as to achieve the effect of limiting the angle of the current lamp panel 21.

[0034] Specifically, the two movable seats 41 are respectively fixed to one end of the top of the protective plate 3, and the T-shaped blocks 46 of the two limiting mechanisms 4 are respectively fixed to one end of the top of the bracket mechanism 1 close to the protective plate 3. The T-shaped blocks 46 are respectively inserted into the inside of the T-shaped slots 45, and the outer dimensions of the T-shaped blocks 46 match the inner dimensions of the T-shaped slots 45. When the light board 21 needs to be rotated and folded to adjust the illumination angle, the L-shaped block 44 drives the spring rod 43 to stretch by lifting, so that the fixed T-shaped block 46 can be moved out of the T-shaped slot 45. After the connection is disconnected, the protective plate 3 can be moved through the movable seat. The protective plate 3 and the light board 21 are rotated by adjusting the lever 22 and the sliding ball 23, so that the light board 21 can be rotated as required by the user. When the protective plate 3 and the light board 21 are both vertical, the L-shaped block 44 can be stretched again, and the T-shaped block 46 can be located below the T-shaped slot 45 by rotating the movable seat 41. After the L-shaped block 44 is released, the L-shaped block 44 can be inserted into the T-shaped slot 45 with the help of the pulling force of the spring rod 43, so that there is a limit between the U-shaped frame 11 and the protective plate 3, so that the protective plate 3 can stably protect the light board 21 when it is carried.

[0035] Specifically, the top of the protection plate 3 is flush with the top of the lamp board 21 , so that it can fully protect the lamp board 21 .

[0036] Working principle:

[0037] The light board 21 achieves a certain lifting effect by raising and lowering the adjustment rod 22 in the through groove 12 and the sliding ball 23 in the ball groove 13. It can be adjusted as needed and can be flipped for protection in the later stage. When the folding angle is appropriate, the rotation of the squeezing nut 24 can resist the outer wall of the U-shaped frame 11, thereby limiting the position of the U-shaped frame 11 when folded. After the light board 21 is flipped, the irradiation surface of the light board 21 faces the protective plate 3, and the squeezing nut 24 squeezes the outer wall of the U-shaped frame 11, so that the protection of the protective plate 3 to the light board 21 has better stability.

[0038] The circuits, electronic components and control modules involved are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by the utility model does not involve improvements to software and methods.

Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present utility model.
