[0024] Optionally, the fixing plate has a connecting end opposite to the fixing end, and the connecting end is rotatably connected to the base, so that the fixing end can rotate around the connecting end and be hidden at the bottom of the base.

[0025] By adopting the above technical solution, when it is necessary to use a pin shaft or an expansion bolt to fix the base, the fixing plate is rotated, and then the fixed end of the fixing plate is rotated to the outside of the base, so as to facilitate the construction personnel to fix the base; and when the lighting device is stored, the fixing plate is rotated so that the fixed end is rotated to the bottom of the base, so that the fixing plate is hidden to the bottom of the base, thereby reducing the footprint of the lighting device, thereby facilitating the transportation of the lighting device.

[0045] Reference Figures 1 to 7 , discloses a lighting device for construction, which includes a base 1, a support rod 2 detachably connected to the base 1, and a lighting lamp 3 detachably connected to the top of the support rod 2. The base 1 has a receiving cavity inside, and a counterweight box 4 with an open top is provided in the receiving cavity. The side of the base 1 is provided with an opening connected to the receiving cavity, and the counterweight box 4 can be pulled out through the opening. The volume of the counterweight box 4 is larger than the volume of the lighting lamp, so that the lighting lamp 3 can be placed inside the counterweight box 4 through the opening.

[0046] When using the lighting device in the present application, first pull out the counterweight box 4 from the inside of the bottom through the opening, then take out the lighting lamp 3 from the counterweight box 4, and then install the lighting lamp 3 to the top of the support rod 2, and then connect the support rod 2 to the base 1 so that the base 1 supports the support rod 2. If the location of the lighting device is uneven, or in windy weather, counterweight blocks can be placed in the counterweight box 4 to increase the gravity of the base 1, thereby achieving the effect of increasing the stability of the lighting device.

[0047] It should be noted that not only counterweight blocks can be placed in the counterweight box 4 for counterweighting, but water can even be poured into the counterweight box 4 or sand and gravel can be placed in the counterweight box 4 for counterweighting.

[0048] At the same time, since the lighting device in the present application has a bottom and a support rod 2, the lighting lamp 3 is arranged on the top of the support rod 2. Therefore, when using the lighting device in the present application, there is no need to press the lighting onto a guardrail or other equipment with a certain height, so as to achieve the effect of facilitating the adjustment of the position of the lighting device.

[0049] In addition, when storing and transporting the lighting device, the lighting lamp 3 can be removed from the support rod 2, and then the lighting lamp 3 can be placed in the counterweight box 4 to store the lighting lamp 3, and then the support rod 2 can be removed from the base 1 to reduce the volume of the lighting device, thereby achieving the effect of facilitating the storage and transportation of the lighting device.

[0050] The present application does not impose any specific limitation on the structure of the lighting lamp 3 . It can be a rechargeable lamp or a lamp that requires a power cord, as long as it can provide lighting.

[0051] The present application does not make any specific limitation on the detachable connection method between the lighting lamp 3 and the support rod 2. Preferably, refer to Figure 1 and Figure 3 A connecting tube 31 that can be sleeved on the support rod 2 is provided at the bottom of the lighting lamp 3.

[0052] Specifically, when assembling the lighting lamp 3, it is only necessary to sleeve the connecting tube 31 at the bottom of the lighting lamp 3 onto the top of the support rod 2, so as to facilitate the installation of the lighting lamp 3 and also facilitate the disassembly of the lighting lamp 3.

[0053] The present application does not make any specific limitation on the detachable connection method between the connecting tube 31 and the support rod 2. Preferably, refer to Figure 1 and Figure 3 The connecting pipe 31 is provided with a locking member 311 that can be passed through the support rod 2.

[0054] Specifically, when installing the lighting lamp 3, the connecting tube 31 at the bottom of the lighting lamp 3 is first sleeved on the top of the support rod 2, and then the locking piece 311 is passed through the connecting tube 31 and the support rod 2 to increase the connection stability between the connecting tube 31 and the support rod 2, thereby increasing the stability of the lighting lamp 3 and greatly reducing the safety hazards of the lighting device.

[0055] The present application does not specifically limit the structure of the locking member 311. Preferably, the locking member 311 is a bolt pair to increase the connection stability between the connecting tube 31 and the support rod 2, thereby further increasing the connection stability between the lighting lamp 3 and the support rod 2. In other embodiments, the locking member 311 may also be a pin.

[0056] In other embodiments, the connecting pipe 31 may also be threadedly connected to the supporting rod 2 .

[0057] In other embodiments, the lighting lamp 3 may also be detachably connected to the support rod 2 via bolts.

[0058] This application does not make any specific limitation on the detachable connection method between the support rod 2 and the base 1. Preferably, refer to Figures 1 to 4 A fixing tube 11 is provided on the top of the base 1 and is sleeved on the outside of the support rod 2 . The support rod 2 is detachably connected to the fixing tube 11 .

[0059] Specifically, when installing the support rod 2, first align the support rod 2 with the fixed tube 11, and then lower the support rod 2 so that the support rod 2 passes through the fixed tube 11, thereby completing the installation of the support rod 2 and achieving the effect of facilitating the assembly and disassembly of the support rod 2.

[0060] Preferably, the support rod 2 is threadedly connected to the fixing tube 11 to reduce the difficulty of connecting the support rod 2 and the fixing tube 11 and increase the difficulty of disassembling and assembling the lighting device.

[0061] Further, refer to Figure 3 、 Figure 4 and Figure 5 The top of the base 1 has an avoidance gap, in which an elastic arm 12 is provided. The elastic arm 12 has a stop portion 121 protruding toward the inside of the base 1. After the support rod 2 is connected to the fixed tube 11, the support rod 2 acts on the elastic arm 12 so that the elastic arm 12 undergoes elastic deformation and the stop portion 121 can cooperate with the counterweight box 4 to stop.

[0062] It can be understood that the avoidance gap is set corresponding to the fixing tube 11, and the bottom of the support rod 2 is closed.

[0063] Specifically, when using the lighting device in the present application, the counterweight box 4 is first pulled out through the opening, and then the lighting lamp 3 is taken out and connected to the support rod 2, and then the counterweight block is placed in the counterweight box 4 and the counterweight box 4 is pushed back into the base 1, and then the support rod 2 is connected to the fixed tube 11. At this time, the support rod 2 acts on the elastic arm 12, and the elastic arm 12 undergoes elastic deformation, so that the stop portion 121 can cooperate with the counterweight box 4 stop to avoid the counterweight box 4 from being pulled out through the opening at this time, thereby avoiding the lighting device from tilting, so as to ensure the stability of the lighting device and greatly reduce the safety hazards of the lighting device.

[0064] After the support rod 2 is separated from the fixing tube 11, the elastic arm 12 recovers its deformation under the action of its own elasticity, so that the stop portion 121 cannot cooperate with the counterweight box 4, thereby ensuring that the counterweight box 4 can be pulled out through the opening.

[0065] The present application does not specifically limit the structure of the stopper 121. Preferably, the stopper 121 is a block structure provided on the elastic arm 12. In other embodiments, the stopper 121 can also be a protrusion or other structures that can achieve a stopping effect.

[0066] Further, refer to Figure 3 、 Figure 4 and Figure 5 The inner wall of the counterweight box 4 is provided with an extension piece 41 extending toward the inside of the counterweight box 4. The stop portion 121 can cooperate with the extension piece 41 to stop, thereby making the installation position of the fixed tube 11 close to the center of the base 1 to increase the balance of the lighting device, thereby further increasing the stability of the lighting device.

[0067] In other embodiments, the support rod 2 may also be detachably connected to the base 1 via bolts.

[0068] In a preferred embodiment, referring to Figure 2 and Figure 3 A clamping member 13 is provided on the side of the base 1. The clamping member 13 and the side wall of the base 1 together form a clamping space with a through opening at the top, and the support rod 2 can be placed in the clamping space.

[0069] Specifically, after separating the support rod 2 from the base 1, the support rod 2 can be placed into the clamping space through the through opening to store the support rod 2 on the side of the base 1, so as to facilitate the transportation of the lighting device. At the same time, storing the support rod 2 on the side of the base 1 can also avoid the loss of the support rod 2, so that the lighting device can be continued to be used next time.

[0070] Further, refer to Figure 2 and Figure 3The clamping member 13 is detachably connected to the base 1 and can be placed in the counterweight box 4 through the opening. After the support rod 2 is removed from the side of the base 1, the clamping member 13 can be removed from the side of the base 1 so that the clamping member 13 can be placed in the counterweight box 4 to avoid the situation where the clamping member 13 may cause danger to the construction workers, thereby improving the construction workers' usage experience.

[0071] The present application does not specifically limit the manner in which the clamping member 13 is detachably connected to the base 1. Preferably, a slide rail is provided on the side of the base 1, and the clamping member 13 is provided with a sliding portion slidably connected to the slide rail to achieve detachable connection between the clamping member 13 and the base 1. In other embodiments, the clamping member 13 is detachably connected to the side of the base 1 by bolts.

[0072] In a preferred embodiment, referring to Figure 5 and Figure 6 A fixing piece 14 is provided at the bottom of the base 1 . The fixing piece 14 has a fixing end located outside the base 1 , and a fixing hole 141 is provided at the fixing end.

[0073] Specifically, when using the lighting device in windy weather, a pin can be used to fix the base 1 so that the pin passes through the fixing hole 141 and penetrates below the ground to increase the stability of the lighting device. At the same time, expansion bolts can also be used to fix the lighting device to the hardened ground.

[0074] Further, refer to Figure 5 and Figure 6 The fixing piece 14 has a connecting end opposite to the fixed end, and the connecting end is rotatably connected to the base 1 so that the fixed end can rotate around the connecting end and be hidden at the bottom of the base 1.

[0075] It is understandable that the fixing plate 14 has a rotating shaft rotatably connected to the base 1 , and the rotating shaft is arranged perpendicular to the fixing plate 14 so that the fixing plate 14 can rotate within the plane where the fixing plate 14 is located.

[0076] When it is necessary to use a pin or expansion bolt to fix the base 1, the fixing plate 14 is rotated, and then the fixed end of the fixing plate 14 is rotated to the outside of the base 1, so as to facilitate the construction workers to fix the base 1; and when the lighting device is stored, the fixing plate 14 is rotated so that the fixed end is rotated to the bottom of the base 1, so that the fixing plate 14 is hidden to the bottom of the base 1, so as to reduce the footprint of the lighting device, thereby facilitating the transportation of the lighting device.

[0077] The present application does not make any specific limitation on the structure of the support rod 2. Preferably, refer to Figure 1 、 Figure 2 and Figure 7The support rod 2 includes a support section 21 and a plurality of telescopic sections 22 embedded in each other. The telescopic section 22 located on the outermost side is passed through the support section 21 so that the height of the lighting device can be adjusted, and a limit rod 221 and a spring 222 acting on the limit rod 221 are provided inside each telescopic section 22. The limit rod 221 is arranged perpendicular to the telescopic section 22, and the telescopic section 22 is provided with a through hole corresponding to the limit rod 221 for at least part of the limit rod 221 to extend through the through hole. The support section 21 and the telescopic section 22 located on the outside are both provided with locking holes 211 corresponding to the limit rod 221. The limit rod 221 can be extended into the locking hole 211 under the action of the spring 222 to increase the stability of the support rod 2.

[0078] Preferably, the outer end of the limiting rod 221 is spherical, so that the limiting rod 221 can be pressed into the interior of the telescopic section 22, thereby facilitating the compression of the support rod 2. The inner end of the limiting rod 221 is provided with a blocking piece, which can cooperate with the inner wall of the telescopic section 22 to restrain the limiting rod 221, preventing the limiting rod 221 from being dislodged through the through hole under the action of the spring 222.

[0079] Preferably, multiple groups of locking holes 211 corresponding to the limiting rods 221 are provided along the axial direction of the support rod 2, so that the support rod 2 can be adjusted to multiple sizes, thereby increasing the flexibility of the lighting device.

[0080] In other embodiments, the support rod 2 may also be a non-retractable rod-shaped structure.
