[0018] A protective device for work lights, such as Figure 1 , 2As shown in Figures 3 and 4, the enclosure includes a housing 1 with an opening on its top side. A movable plate 2 is slidably mounted inside the housing 1. A sliding groove is provided on the housing 1, and a slider is slidably fitted within the groove. The slider is fixedly mounted on the movable plate 2. A threaded hole 3 is provided on the movable plate 2, and a screw 4 is threadedly fitted into the threaded hole 3. The screw 4 is rotatably mounted in a pre-drilled hole on the housing 1 via a sealed bearing 5, and the screw 4 passes through the housing 1. The outer circumference of the screw 4 is fixedly connected to the inner circumference of the sealed bearing 5, and the outer circumference of the sealed bearing 5 is fixedly mounted on the pre-drilled hole in the housing 1. A work light 6 is fixedly mounted on the movable plate 2, with the illumination direction of the work light 6 facing to the left. A cover plate 7 is fixedly mounted on the top side of the work light 6, and the cover plate 7 abuts against the top side of the housing 1. A bracket is provided on one side of the housing 1. This utility model has a simple structure and ingenious design. When in use, the work light 6 extends out of the housing 1 for illumination, facilitating work. When not in use, the work light 6 is retracted into the housing 1, which protects it from damage by impacts. It is easy to operate, meets market demands, and is suitable for widespread adoption. To use this utility model, first place the bracket on the ground and rotate the screw 4. The screw 4 moves the moving plate 2 up and down, which in turn moves the work light 6 and the cover plate 7 up and down. When the moving plate 2 moves the work light 6 upwards and fully extends it out of the housing 1, the left side of the work light 6 can be used for illumination. When not in use, rotating the screw 4 retracts the work light 6 into the housing 1, with the cover plate 7 abutting against the housing 1. At this point, the housing 1 and cover plate 7 provide protection, preventing damage to the work light 6 from impacts. The sealing bearing 5 increases the airtightness of the housing 1, preventing rainwater from entering.
[0019] Specifically, as shown in the figure, the bracket in this embodiment includes a first fixing plate 20, a second fixing plate 21, a third fixing plate 22, and a fourth fixing plate 23. The bottom of the housing 1 is rotatably mounted on one side of the first fixing plate 20 via a damping hinge 24. The other side of the first fixing plate 20 is also rotatably mounted on one side of the second fixing plate 21 via a damping hinge 24. The other side of the second fixing plate 21 is also rotatably mounted on one side of the third fixing plate 22 via a damping hinge 24. The other side of the third fixing plate 22 is also rotatably mounted on one side of the fourth fixing plate 23 via a damping hinge 24. The first fixing plate 20, the second fixing plate 21, the third fixing plate 22, and the fourth fixing plate 23 can be folded up to surround the box 1 in the middle to form a second protection. The fourth fixing plate 23 is placed on the ground as a base, and the second fixing plate 21, the first fixing plate 20, and the box 1 are unfolded in sequence. At this time, the first fixing plate 20, the second fixing plate 21, the third fixing plate 22, and the fourth fixing plate 23 can be used as a support frame. The damping hinge 24 has a damping effect, which can suspend the corresponding fixing plate 20, the second fixing plate 21, the third fixing plate 22, and the box 1 in a certain position, making it easy to adjust the lighting direction and height of the work light 6.
[0020] Specifically, such as Figure 3 As shown, the damping hinge 24 in this embodiment includes two fixing blocks 30. Each fixing block 30 has a through slot 31, and each through slot 31 has a bevel gear groove 32. Bevel gears 33 are meshed with each bevel gear groove 32. One end of a spring telescopic shaft 34 is fixedly connected to the inner side of each bevel gear 33. The spring telescopic shafts 34 are rotatably mounted on the through slots 31. The other ends of the two spring telescopic shafts 34 are fixedly connected via a rotating shaft 35. The movable end of the spring telescopic shaft 34 is fixedly mounted on the inner side of the bevel gear 33, and the fixed end of the spring telescopic shaft 34 is fixedly mounted on the rotating shaft 35. The through slots 31, bevel gears 33, spring telescopic shafts 34, and rotating shaft 35 are coaxially arranged. The fixed end of the spring telescopic shaft 34 is rotatably mounted via a bearing. The outer periphery of the fixed end of the spring telescopic shaft 34 is fixedly connected to the inner periphery of the bearing, which is mounted on the through slot 31. The outer periphery of the bearing is fixedly mounted on the through slot 31. The rotating shaft 35 and the fixing block 30 are respectively fixedly mounted on the corresponding first fixing plate 20, second fixing plate 21, third fixing plate 22, fourth fixing plate 23 and housing 1. The fixing block 30 in each damping hinge 24 is respectively fixedly mounted on one side of the first fixing plate 20, one side of the second fixing plate 21, one side of the third fixing plate 22 and one side of the fourth fixing plate 23. The rotating shaft 35 in each damping hinge 24 is respectively fixedly mounted on the bottom of the corresponding housing 1, the other side of the first fixing plate 20, the other side of the second fixing plate 21 and the other side of the third fixing plate 22 through the connecting plate. When the corresponding first fixed plate 20, second fixed plate 21, third fixed plate 22, or housing 1 is rotated, the corresponding rotating shaft 35 is driven to rotate. The rotating shaft 35 drives the corresponding spring telescopic shaft 34 to rotate. The rotation of the spring telescopic shaft 34 drives the bevel gear 33 to rotate. Since the bevel gear 33 meshes with the bevel gear groove 32, the bevel gear 33 needs to move outward before it can rotate. When the rotating shaft 35 rotates, it drives the spring telescopic shaft 34 to extend, thereby driving the bevel gear 33 to move outward. When the rotating shaft 35 does not rotate, the spring telescopic shaft 34 can keep the bevel gear 33 meshing with the bevel gear groove 32, so that the corresponding first fixed plate 20, second fixed plate 21, third fixed plate 22, or housing 1 is suspended in a certain position for easy adjustment and use.
[0021] Furthermore, as shown in the figure, the fourth fixing plate 23 in this embodiment is hollow inside, and a water inlet (not shown in the figure) is provided on the fourth fixing plate 23. A sealing cap 40 is threaded onto the water inlet. Rotating to open the sealing cap 40 and adding water into the fourth fixing plate 23 through the water inlet can provide counterweight, increasing the stability of the fourth fixing plate 23 when it is used as a base on the ground.
[0022] Furthermore, as shown in the figure, a sealing ring 50 is provided between the top of the housing 1 and the cover plate 7 in this embodiment, and the sealing ring 50 is fixedly installed on the housing 1. The sealing ring 50 can increase the sealing performance between the housing 1 and the cover plate 7.
[0023] Furthermore, as shown in the figure, in this embodiment, the second fixing plate 21, the third fixing plate 22, and the fourth fixing plate 23 are respectively fixed with a stop 60. The stop 60 can respectively abut against one side of the corresponding first fixing plate 20, second fixing plate 21, and third fixing plate 22. When the first fixing plate 20, second fixing plate 21, third fixing plate 22, and fourth fixing plate 23 are folded around the box 1, the stop 60 on the fourth fixing plate 23 abuts against the third fixing plate 22, the stop 60 on the third fixing plate 22 abuts against the second fixing plate 21, and the stop 60 on the second fixing plate 21 abuts against the first fixing plate 20. The stop 60 can play a limiting role, preventing the corresponding first fixing plate 20, second fixing plate 21, and third fixing plate 22 from continuing to rotate.
[0024] Furthermore, as shown in the figure, a limiting block 70 is fixedly provided on the fourth fixing plate 23 in this embodiment. The limiting block 70 can abut against the bottom side of the box 1. When the limiting block 70 abuts against the box 1, it can provide support for the box 1, making it convenient to use.
[0025] Furthermore, as shown in the figure, a coaxial handwheel 80 is fixedly provided at one end of the screw 4 in this embodiment. Rotating the screw 4 by turning the handwheel 80 makes it more convenient and less strenuous.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
