An adjusting mechanism is provided on the outer sides of the first arc-shaped frame and the second arc-shaped frame, and the adjusting mechanism extends into the first arc-shaped frame and the second arc-shaped frame.

[0007] The adjusting mechanism includes two annular grooves. The cross-sections of the two annular grooves are spherical. A first sphere is embedded in each of the two annular grooves. The first spheres are all matched with the two annular grooves. A connecting rod is fixedly connected to the top of each first sphere. The top end of the connecting rod is fixedly connected to a frame body. A roller is embedded in the frame body. A rotating plate is fixedly sleeved on the outer side of the roller. Two second spheres are embedded in one side of the rotating plate. Mounting brackets are fixedly connected to the bottoms of the two second spheres. Lighting lamps are installed on one side of each of the two mounting brackets. A collar and a spring are sleeved on the outer side of the roller. The spring is located in front of the collar and is fixedly connected to the collar. The front end of the spring is fixedly connected to a sleeve. A square rod is fixedly connected to the front end of the roller. The sleeve is sleeved on the outer side of the square rod. A handle is fixedly connected to the front side of the sleeve. A plurality of card slots are formed on the front side of the frame body. The plurality of card slots are evenly distributed. A plug is fixedly connected to the rear side of the handle. The rear end of the plug extends into one of the card slots. An auxiliary component is provided on the outer side of the plug.

[0008] Furthermore, the auxiliary component includes two anti-slip rings, which are respectively fixedly connected to the inner sides of the first arc-shaped frame and the second arc-shaped frame.

[0009] Through the above technical solution, by setting two anti-slip rings, the friction between the two arc-shaped frames 1 and 2 and the hook can be strengthened, thereby making the fixing effect better.

[0010] Furthermore, the connection between the roller and the frame body is movably connected through a bearing, the connection between the collar and the frame body is movably connected through a bearing, and two square blocks are fixedly connected to the bottom of the frame body. The bottoms of the two square blocks are both in contact with the top of the arc-shaped frame 1.

[0011] Through the above technical solution, by setting two square blocks, the positioning of the frame body can be achieved, avoiding the change of the position of the frame body in the later stage.

[0012] Furthermore, the arc-shaped frame 1 and the arc-shaped frame 2 are rotationally connected through a mounting rod, and fixing blocks are fixedly connected to the outer sides of the arc-shaped frame 1 and the arc-shaped frame 2.

[0013] Furthermore, T-shaped grooves are provided on the outer sides of the two fixing blocks, and T-shaped blocks are embedded in the two T-shaped grooves.

[0014] Through the above technical solution, through the cooperation of the two fixing blocks, the two T-shaped grooves and the two T-shaped blocks, it is convenient for the staff to quickly install and fix the arc-shaped frame 1 and the arc-shaped frame 2 on the outside of the hook in the later stage.

[0015] Furthermore, the two T-shaped blocks respectively match the two T-shaped grooves, and handles are fixedly connected to the tops of the two T-shaped blocks.

[0016] Through the above technical solution, by setting the handles, it is convenient for the staff to draw out the two T-shaped blocks from the inside of the two fixing blocks in the later stage.

[0017] Furthermore, grooves are provided on both sides of the handle, and the two grooves are symmetrically arranged with the center line of the handle as the axis of symmetry.

[0018] Through the above technical solution, by providing the two grooves, it is convenient for the staff to take the handle in the later stage.

[0019] In summary, the present application includes the following beneficial technical effects:

[0020] By pulling the handle, after the plug pin is disengaged from the card slot, then rotating the handle, the rotating plate drives the two lighting lamps to be adjusted to the specified angle, and then the handle can be released. The spring rebounds to drive the plug pin to extend into the corresponding card slot again to complete the positioning of the frame body. Since the two lighting lamps are movably connected to the rotating plate through two spheres 2, the irradiation angles of the two lighting lamps can be quickly adjusted. Through the above structure, the problem that due to the lack of lighting function, the position of the hook is often darker, which causes the staff to be unable to efficiently and clearly master the position of the hook and the work of the staff will be greatly affected is solved.

[0031] Embodiment:

[0032] An embodiment of the present application discloses a lighting device for a truck crane. Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , including a first arc-shaped frame 1 and a second arc-shaped frame 2. An adjusting mechanism is provided on the outer sides of the first arc-shaped frame 1 and the second arc-shaped frame 2, and the adjusting mechanism extends to the inside of the first arc-shaped frame 1 and the second arc-shaped frame 2;

[0033] The adjusting mechanism includes two annular grooves. The cross-sections of the two annular grooves are spherical. A first sphere 3 is embedded in the two annular grooves. The first spheres 3 are all matched with the two annular grooves. A connecting rod 4 is fixedly connected to the top of the first sphere 3. The top of the connecting rod 4 is fixedly connected to a frame body 5. A roller 6 is embedded in the frame body 5. A rotating plate 7 is fixedly sleeved on the outer side of the roller 6. Two second spheres 8 are embedded in one side of the rotating plate 7. Mounting brackets 9 are fixedly connected to the bottoms of the two second spheres 8. Lighting lamps 10 are installed on one side of each of the two mounting brackets 9. A collar 11 and a spring 12 are sleeved on the outer side of the roller 6. The spring 12 is located in front of the collar 11 and fixedly connected to the collar 11. A sleeve 13 is fixedly connected to the front end of the spring 12. A square rod 14 is fixedly connected to the front end of the roller 6. The sleeve 13 is sleeved on the outer side of the square rod 14. A handle 15 is fixedly connected to the front side of the sleeve 13. A plurality of card slots are formed on the front side of the frame body 5, and the plurality of card slots are evenly distributed. A latch 16 is fixedly connected to the rear side of the handle 15, and the rear end of the latch 16 extends into one of the card slots;

[0034] Please refer to Figure 1 、 Figure 4 and Figure 5, an auxiliary component is provided outside the bolt 16. The auxiliary component includes two anti-slip rings 17. The two anti-slip rings 17 are respectively fixedly connected to the inner sides of the first arc-shaped frame 1 and the second arc-shaped frame 2. The connection between the roller 6 and the frame body 5 is movably connected through a bearing, and the connection between the collar 11 and the frame body 5 is movably connected through a bearing. Two square blocks 18 are fixedly connected to the bottom of the frame body 5. The bottoms of the two square blocks 18 are both in contact with the top of the first arc-shaped frame 1. By providing the two anti-slip rings 17, the friction between the two first arc-shaped frames 1 and the second arc-shaped frame 2 and the hook can be strengthened, so that the fixing effect can be better. At the same time, by providing the two square blocks 18, the frame body 5 can be positioned to prevent the position of the frame body 5 from changing later;

[0035] Please refer to Figure 1 , Figure 2 and Figure 3 , the first arc-shaped frame 1 and the second arc-shaped frame 2 are rotatably connected through a mounting rod 22. Fixed blocks 19 are fixedly connected to the outer sides of the first arc-shaped frame 1 and the second arc-shaped frame 2. T-shaped grooves are opened on the outer sides of the two fixed blocks 19. T-shaped blocks 20 are embedded in the two T-shaped grooves. Through the cooperation of the two fixed blocks 19, the two T-shaped grooves and the two T-shaped blocks 20, it is convenient for the staff to quickly install and fix the first arc-shaped frame 1 and the second arc-shaped frame 2 outside the hook later;

[0036] Please refer to Figure 3 , the two T-shaped blocks 20 respectively match the two T-shaped grooves. Handles 21 are fixedly connected to the tops of the two T-shaped blocks 20. Grooves are opened on both sides of the handle 21. The two grooves are symmetrically arranged with the midline of the handle 21 as the axis of symmetry. By providing the handle 21, it is convenient for the staff to draw out the two T-shaped blocks 20 from the two fixed blocks 19 later. At the same time, by opening the two grooves, it is convenient for the staff to take the handle 21 later.

[0037] The implementation principle of this embodiment is as follows: First, open the first arc-shaped frame 1 and the second arc-shaped frame 2 through the mounting rod 22, then sleuth the first arc-shaped frame 1 and the second arc-shaped frame 2 outside the hook, and lock them through the mutual cooperation of the two T-shaped blocks 20, the two T-shaped grooves and the handle 21. Because there are two anti-slip rings 17, the friction between the two first arc-shaped frames 1 and the second arc-shaped frame 2 and the hook can be strengthened, so that the fixing effect can be better;

[0038] Then, the frame 5 can be rotated by the sphere 1 with the midline of the arc-shaped frame 1 and the arc-shaped frame 2 as the axis. When the two lighting lamps 10 are rotated to the specified position, the handle 15 can be pulled, and then the bolt 16 will move accordingly. At this time, the spring 12 will be stressed and deformed, being in a stretched state. When the bolt 16 is disengaged from the card slot, the handle 15 can be rotated to adjust the position of the bolt 16. Since the square rod 14 matches the sleeve 13, the roller 6 can be driven to rotate through the sleeve 13. At this time, the roller 6 will drive the rotating plate 7 to rotate. When the two lighting lamps 10 are adjusted to the specified angle by the rotating plate 7, the handle 15 can be released, and the spring 12 rebounds to drive the bolt 16 to extend into the corresponding card slot again, completing the positioning of the frame 5. Since the two lighting lamps 10 are movably connected to the rotating plate 7 through two spheres 2, the irradiation angles of the two lighting lamps 10 can be quickly adjusted. Through the above structure, the problem that due to the lack of lighting function, the position of the lifting hook is mostly dark, which will cause the staff to be unable to efficiently and clearly master the position of the lifting hook, and the work of the staff will be greatly affected is solved.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
