[0055] In the description of the present invention, the terms "top", "center", "bottom", "up", "down", "horizontal", "vertical", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying the only implementation method.

[0056] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings:

[0057] like Figure 1 , Figure 2 As shown, the structure of the utility model includes two lamp head assemblies 1, a connecting assembly 2, a control box assembly 3, and a tripod 4. The two lamp head assemblies 1 have the function of lighting, the connecting assembly 2 has the function of connecting the two lamp head assemblies 1 and the control box assembly 3 and adjusting the azimuth angle of the lamp head assembly 1, the control box assembly 3 has the function of controlling the lighting effect of the two lamp head assemblies 1 and the power switch, and the tripod 4 has the function of supporting the entire work lamp.

[0058] The connection structure relationship of each component is as follows: the two lamp head components 1 are respectively connected to the lamp head connecting parts 21 in the connecting component 2, the lamp head frame component 25 of the connecting component 2 is connected to the tubular part of the upper half of the control box main body 31 in the control box component 3, and the main support rod 41 of the tripod bracket 4 is connected to the tubular part of the lower half of the control box main body 31 in the control box component 3.

[0059] like Figure 3 , Figure 4 , Figure 5 As shown, the structure of the connecting assembly 2 includes: a lamp holder frame 25, a lamp holder buckle 24, a lamp holder connecting piece 21, a rotating rod connecting piece 22, and a rotating rod limiting piece 23.

[0060] The upper half of the lamp holder connector 21 is triangular, with several screw holes for connecting with the lamp holder assembly 1, and the lower half is provided with two legs with holes for buckling with the rotating rod connector 22. When the lamp holder connector 21 is connected with the rotating rod connector 22, the lamp holder assembly 1 can be controlled to rotate about 180 degrees in the vertical direction.

[0061] The overall shape of the rotating rod connector 22 is Y-shaped, with two legs at the upper end for connecting with the lamp holder connector 21, and a cylinder with an annular groove at the lower end. The structure of the rotating rod connector 22 includes a rotating rod connector I 221 and a rotating rod connector II 222, and the purpose of this design is to facilitate the connection with the lamp holder connector 21 during assembly.

[0062] like Figure 6 As shown, the rotating rod limiting piece 23 is shaped like a semi-cylindrical shell, and a limiting strip 231 is provided on the top of one side of the shell wall. There is a circular tenon in the center of the shell wall, which is the circular tenon 232 of the limiting piece, and there is a semicircular protrusion at each end of the shell wall, which is the semicircular protrusion 233 of the limiting piece. When the two rotating rod limiting pieces 23 are fixedly connected to the rotating rod connecting piece 22, every two semicircular protrusions 233 of the limiting piece will combine to form a circular tenon, and the shape of this circular tenon is the same as the circular tenon 232 of the limiting piece in the center of the rotating limit piece shell wall, and every two of the semicircular ring-shaped limiting strips 231 will also combine to form a circular ring-shaped limiting strip.

[0063] like Figure 7 As shown, there is a circular groove in the center of the inner wall of the lamp holder buckle 24, which is the circular mortise 241 of the buckle inner wall, and there is a semicircular groove at each end of the inner wall, which is the semicircular groove 242 of the buckle inner wall. The circular mortise 241 of the buckle inner wall can be exactly fitted with the circular tenon 232 of the limiting plate.

[0064] like Figure 5 , Figure 8 As shown, the overall structure of the lamp holder frame 25 is T-shaped, and there is a circular groove at the center of the inner wall on both sides of the lamp holder frame 25, which is the circular mortise 251 of the inner wall of the lamp holder frame. The shape of the circular mortise 251 of the inner wall of the lamp holder frame is the same as the shape of the circular mortise 241 of the inner wall of the lamp holder buckle 24. There is a semicircular groove at both ends of the inner wall of the two sides of the lamp holder frame, which is the semicircular groove 252 of the inner wall of the lamp holder frame. When the lamp holder frame 25 is buckled with the lamp holder 24, the two semicircular grooves 252 of the inner wall of the lamp holder frame will combine with the semicircular grooves 242 of the inner wall of the buckle to form a circular mortise, and the shape of this circular mortise is also the same as the circular mortise 251 of the inner wall of the lamp holder frame on both sides of the lamp holder frame 25 and the circular mortise 241 of the inner wall of the upper end of the inner wall of the lamp holder buckle.

[0065] When assembling the entire connection assembly 2, the two rotating rod limit plates 23 are attached to the lower end of the rotating rod connector 22, so that each two semicircular protrusions are combined into a circular tenon. At this time, there are four circular tenons at the lower end of the rotating rod connector 22. Corresponding to the four circular tenons, when the lamp holder buckle 24 and the lamp holder frame 25 are combined, there are also four circular mortises in the inner wall of the cavity formed by the two. The combination of the rotating rod connector 22 and the rotating rod limit plate 23 is placed between the lamp holder frame 25 and the lamp holder buckle 24. After ensuring that the circular tenons can be correspondingly embedded in the circular tenons, the lamp holder buckle 24 and the lamp holder frame 25 are combined and connected. The mortise and tenon structure of the circular tenon and the circular tenon ensures the stability of the structure of the connection assembly 2.

[0066] When the rotating rod connecting member 22 is fixed between the lamp holder frame and the lamp holder buckle 24, it can realize nearly 360-degree rotation in the horizontal direction through the annular gap between the rotating rod limiting piece 23 and the rotating rod connecting member 22. The annular groove at the lower end of the rotating rod connecting member 22 is used to make the rotation more flexible and smooth. The buckle on the rotating rod connecting member 22 is clamped on the annular limiting strip composed of the semicircular limiting strips 231. The limiting strip limits the vertical position of the rotating rod connecting member 22, ensuring that the rotating rod connecting member 22 will not move in the vertical direction when rotating. There is a raised limiting block on the semicircular limiting strip 231 on the rotating rod limiting piece 23 on the side of the lamp holder frame 25, which is used to limit the rotation angle of the rotating rod connecting member 22, ensuring that the two working lamps of the lamp holder assembly 1 will not be exposed to each other when rotating, thereby causing damage to the lamp group.

[0067] The lower half of the lamp holder frame 25 is connected to the upper half of the control box body 31. The lower half of the lamp holder frame 25 also ensures that the entire part consisting of the two lamp holder assemblies 1 and the connecting assembly 2 can achieve horizontal 360-degree rotation.

[0068] The control box assembly 3 includes a control box body 31 and a battery part 32. The battery part 32 is located in the cavity of the main support rod 41 in the tripod 4 and is used to supply power to the control box body 31 and the two lamp head assemblies 1. The control box body 31 is used to control the switch of the power supply and the brightness of the lamp head assembly 1.

[0069] like Fig. 9As shown, the tripod 4 includes a main support rod 41, a height adjustment knob 42, a fixing knob 43, and a support leg 44. The support leg 44 is fixed to the main support rod 41 through a sliding connector 45. The cavity inside the main support rod 41 includes a height adjustment rod that can be extended and retracted up and down. The height adjustment knob 42 is located in the upper half of the main support rod 41. The height of the main support rod 41 can be adjusted by fixing the position of the height adjustment rod. The fixing knob 43 is located at the connection between the support rod of the main support rod 41 and the support leg 44. When the tripod 4 is unfolded, the branches of the support leg 44 are unfolded in a triangular shape, and the auxiliary flat iron of the support leg 44 is fully extended to stabilize the branches and the main support rod 41. At this time, tighten the fixing knob 43, and the position of the tripod 4 will be fixed. When storage and merging are required, the fixing knob 43 is loosened, and after each branch pipe of each supporting leg 44 and the auxiliary supporting flat iron are combined and stored, the fixing knob 43 is tightened, and the storage state of each supporting leg 44 will be fixed.

[0070] During operation, the two lamp holder assemblies 1 can freely adjust the direction and angle through the connecting assembly 2, that is, the horizontal direction of the two lamp holder assemblies 1 as a whole can be adjusted through the lamp holder frame 25, the vertical direction angle of each lamp holder of the lamp holder assembly 1 can be adjusted through the lamp holder connecting piece 21, and the horizontal direction angle of each lamp holder of the lamp holder assembly 1 can be adjusted through the rotating rod connecting piece 22.

[0071] When the work lamp is stored and carried, the height adjustment knob 42 is rotated at the same time to adjust the height of the main support rod 41 of the tripod 4 to the lowest, and the fixing knob 43 is rotated to keep the tripod 4 in the stored state, so that the overall volume of the tripod 4 is minimized. At this time, the volume of the entire work lamp is greatly reduced compared to the volume when it is unfolded and working, which makes it easier to carry the work lamp when it is not working.
