Technical Field

[0001] The utility model relates to the field of construction lighting, in particular to a portable construction lighting device. Background Art

[0002] When performing construction work, if the light is dim, it is necessary to use lighting equipment to provide light sources so that construction workers can work under sufficient light conditions and improve the safety of the work. Common portable construction lighting equipment is generally equipped with handles, hooks or brackets and other easy-to-carry components to facilitate the fixing and hanging of the lighting equipment. However, such lighting equipment is generally not convenient for construction workers to use by hand. Although there are handheld flashlights to choose from, lighting equipment such as flashlights are difficult to place when construction workers need to perform temporary work, and the light angle is not easy to adjust.

[0003] Therefore, a portable construction lighting device is now developed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings that existing devices are generally not convenient for construction workers to use by hand, flashlights and other lighting equipment are difficult to place when construction workers need to perform temporary work, and the light angle is difficult to adjust, the utility model provides a portable construction lighting device.

DETAILED DESCRIPTION

[0019] The present invention is further described below in conjunction with specific embodiments. It should also be noted that, unless otherwise clearly specified and limited, terms such as: setting, installing, connecting, and connecting should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] Example 1

[0021] A portable construction lighting device, such as Figure 1 and Figure 2 As shown, it includes a base 1, and handles 2 are rotatably connected to the front and rear sides of the base 1, and the handles 2 are provided with adaptation grooves. A rotating rod 3 is rotatably arranged on the right side of the base 1, and a first telescopic rod 4 is rotatably and slidably arranged on the rotating rod 3, and a second telescopic rod 5 is rotatably and slidably connected to the first telescopic rod 4, and a rotating block 7 is rotatably and slidably connected to the second telescopic rod 5. The upper ends of the rotating rod 3, the first telescopic rod 4 and the second telescopic rod 5 are all threadedly connected to adjusting rings 6, and the adjusting rings 6 are provided with power-assisting grooves. The rotating blocks 7 are rotatably connected to connecting blocks 71, and the connecting blocks 71 are connected to lighting lamps 8. A supporting mechanism 9 for improving supporting stability is provided on the base 1.

[0022] like Figure 1-Figure 3 As shown, the support mechanism 9 includes a guide groove frame 91, and the guide groove frame 91 is connected to the front and rear sides of the base 1. Two sliding blocks 92 are slidably connected to the guide groove frame 91, and the sliding blocks 92 are rotatably connected to the first connecting rod 93, and the second connecting rod 94 is rotatably connected between the inner sides of the first connecting rod 93.

[0023] It should be noted that, in the normal state, the handle 2 of the device can be flipped upwards, and then the construction workers directly hold the handle 2 to pick up the device as a whole. At this time, the device can be regarded as a large flashlight, which is convenient for construction workers to carry for lighting and provides a movable and convenient light source. When in specific use, it is only necessary to aim the lighting lamp 8 at the position where lighting is required. The above operation is based on the situation that the construction workers can hold it. When the construction workers cannot hold it and need to participate in the operation, they can pull the second connecting rod 94 outward, so that the first connecting rod 93 rotates and drives the sliding block 92 to slide along the guide groove frame 91. At this time, the sliding blocks 92 will be close to each other. At the same time, push the second connecting rod 94 outward to increase the area of ​​the bottom of the base 1, and then place the base 1 on the ground, then flip the rotating rod 3 upward 90 degrees to achieve a vertical state, and then rotate the adjusting ring 6 to unlock the first telescopic rod 4, the second telescopic rod 5 and the rotating block 7, and then pull the first telescopic rod 4, the second telescopic rod 5 and the rotating block 7 upward according to the required lighting height. After reaching the appropriate position, rotate the adjusting ring 6 in the opposite direction to lock it, and then rotate and adjust the position of the connecting block 71 so that the lighting lamp 8 can illuminate the construction site at a suitable angle, and the construction personnel can participate in the construction work without having to hold the device.

[0024] Example 2

[0025] On the basis of Example 1, Figure 1 , Figure 2 and Figure 4 As shown, it also includes a limiting mechanism 10, which includes a mounting frame 101. The mounting frame 101 is connected to the upper right rear side of the base 1, a rotating member 102 is rotatably arranged on the mounting frame 101, and the lower side of the rotating member 102 has an arc-shaped limiting frame, two torsion springs 104 are connected between the rotating member 102 and the mounting frame 101, a positioning pin 103 is connected to the upper right front side of the base 1, and the front of the rotating member 102 is clamped with the positioning pin 103.

[0026] It should be noted that when the device is in the unfolded state, the rotating rod 3 can be compressed and limited by the rotating member 102 to prevent the rotating rod 3 from accidentally flipping over and unfolding, thereby improving the stability during hand-held use. When the operation needs to be unfolded, the rotating member 102 is disengaged from the positioning pin 103, and then the rotating member 102 is flipped upward 90° so that the rotating rod 3 is no longer blocked. At this time, the rotating rod 3 is flipped upward and unfolded, so that the torsion spring 104 is deformed under the force, and then the rotating member 102 is released, so that the rotating member 102 is flipped and reset under the action of the torsion spring 104, and is engaged with the positioning pin 103 again. At this time, the right side of the rotating member 102 will block and limit the left side of the rotating rod 3 to prevent the rotating rod 3 from accidentally flipping downward, thereby improving the stability of the rotating rod 3 after unfolding.

[0027] Although the present disclosure has been shown and described with reference to specific exemplary embodiments of the present disclosure, it should be understood by those skilled in the art that various changes in form and details may be made to the present disclosure without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents.
