DETAILED DESCRIPTION

[0015] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0016] A work light support frame, such as Figure 1 、 2 , 3, 4, 5, including a cylinder 1, the cylinder 1 includes three arc-shaped plates 2, the cylinder 1 is evenly divided into three arc-shaped plates 2, the arc-shaped plates 2 are respectively hingedly mounted on the connecting rods 3, one end of the connecting rod 3 is hinged on the same vertical tube 4, there are three connecting rods 3, one end of the connecting rod 3 is respectively rotatably mounted on the bottom of the vertical tube 4 through a hinge shaft, and the other end of the connecting rod 3 is respectively rotatably mounted on the arc-shaped plate 2 through a hinge shaft, and the outer periphery of the vertical tube 4 is fixed with several work lights 5. In this embodiment, the work lights 5 are provided with three and are evenly distributed around the circumference. The top of the vertical tube 4 is fixed with a cover plate 6, which contacts and cooperates with the curved plate 2. The bottom side of the curved plate 2 is fixed with a telescopic rod 7 through a connecting plate 9. One end of the telescopic rod 7 is fixedly mounted on the same base 8. The bottom side of the curved plate 2 is fixedly connected to the fixed end of the telescopic rod 7 through a connecting plate 9. The movable end of the telescopic rod 7 is fixedly mounted on the same base 8. The base 8, the cylinder 1, and the vertical tube 4 are coaxially arranged. The base 8 is provided with an adjustment mechanism for controlling the lifting of the vertical tube 4. The utility model has a simple structure and an ingenious design. When in use, the work lamp 5 can be extended out of the cylinder 1 for lighting. At the same time, the lighting height of the work lamp 5 can be adjusted through the adjustment mechanism. When not in use, the work lamp 5 can be stored in the cylinder 1. The cylinder 1 and the cover plate 6 can play a protective role to prevent the work lamp 5 from being damaged by impact from foreign objects. It can meet market demand and is suitable for promotion. When the work lamp 5 is in use, the base 8 and the telescopic rod 7 are placed on the ground, and the vertical tube 4 is controlled to move upward by the adjusting mechanism, and the vertical tube 4 drives the work lamp 5 and the cover plate 6 to move upward, and the connecting rod 3 rotates and drives the curved plate 2 to open outward, and the curved plate 2 drives the telescopic rod 7 to extend. When the connecting rod 3 turns to the horizontal, the vertical tube 4 continues to move upward to drive the curved plate 2 to retract inward, and the telescopic rod 7 is shortened. At this time, the height of the work lamp 5 can be controlled by the adjusting mechanism. When the curved plate 2 is retracted to form a complete cylinder 1, the work lamp 5 is raised to the highest point; when not in use, the vertical tube 4 is controlled by the adjusting mechanism to drive the work lamp 5 to be stored in the cylinder 1 until the cover plate 6 contacts the top side of the curved plate 2. At this time, the cylinder 1 and the cover plate 6 can play a protective role, preventing the work lamp 5 from being damaged by impact from foreign objects when it is put on hold, which is convenient for the storage of the work lamp 5.

[0017] Specifically, as shown in the figure, the adjustment mechanism of this embodiment includes a screw 20, which is rotatably mounted on the base 8. The bottom end of the screw 20 is rotatably mounted on the base 8 through a bearing. The outer periphery of the screw 20 is fixedly connected to the inner periphery of the bearing, and the outer periphery of the bearing is fixedly mounted on the base 8. The inner periphery of the bottom of the vertical tube 4 is provided with a thread, and the inner thread of the vertical tube 4 cooperates with the installation of an externally threaded tube 21. The tops of the vertical tube 4 and the externally threaded tube 21 are closed. The inner periphery of the bottom of the externally threaded tube 21 is also provided with a thread, and the inner thread of the externally threaded tube 21 cooperates with the installation of the screw 20. The externally threaded tube 21 is slidably mounted in the vertical tube 4, and the screw 20 is slidably mounted in the externally threaded tube 21. When the screw 20 is rotated in the forward direction, the screw 20 can drive the externally threaded tube 21 to move upward, and the externally threaded tube 21 can drive the vertical tube 4 to move upward. When the screw 20 is rotated in the reverse direction, the externally threaded tube 21 and the vertical tube 4 can be driven downward, thereby adjusting the height of the vertical tube 4 and the work light 5.

[0018] Specifically, as shown in the figure, the inner circumference of the vertical tube 4 in this embodiment is provided with a first annular groove 30, and the outer circumference of the top end of the externally threaded tube 21 is fixedly provided with a plurality of arc-shaped first sliders 31. The first sliders 31 are slidably mounted on the first annular groove 30. The inner circumference of the externally threaded tube 21 is provided with a second annular groove 32. The outer circumference of the top end of the screw 20 is fixedly provided with a plurality of arc-shaped second sliders 33. The second sliders 33 are slidably mounted on the second annular groove 32. When the externally threaded tube 21 moves upward to the top end of the screw 20, it cannot move upward any further. The bottom end of the second annular groove 32 limits the second sliders 33, preventing the screw 20 from sliding out of the externally threaded tube 21. At this time, the screw 20 drives the externally threaded tube 21 to rotate simultaneously, and the vertical tube 4 continues to move upward. When the vertical tube 4 moves to the top end of the externally threaded tube 21, it cannot move upward any further. The bottom end of the first annular groove 30 limits the first sliders 31, preventing the externally threaded tube 21 from sliding out of the vertical tube 4.

[0019] Furthermore, as shown in the figure, a coaxial hand wheel 40 is fixedly mounted on the outer periphery of the bottom of the screw rod 20 in this embodiment. Rotating the hand wheel 40 at the bottom makes it more convenient and labor-saving to rotate the screw rod 20.

[0020] Furthermore, as shown in the figure, a handle 50 is fixedly provided on the cover plate 6 of this embodiment. When the work light 5 is stored in the cylinder 1, the handle 50 makes it easier to lift the device and place it in a designated position.

[0021] Furthermore, as shown in the figure, a sealing gasket 61 is provided between the cover plate 6 and the curved plate 2 in this embodiment. The cover plate 6 has an annular groove 60 formed therein, and the sealing gasket 61 is installed in the annular groove 60. The sealing gasket 61 abuts and contacts the curved plate 2. The sealing gasket 61 can enhance the sealing between the cover plate 6 and the curved plate 2, thereby providing a rainproof effect.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
