[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] The present invention provides a stadium lamp with an adjustable irradiation angle, as shown in Figure 1 , Figure 2 and Figure 4 , which includes a lamp post 1. A mounting base 2 is fixedly connected to the bottom of the lamp post 1. The side surface of the lamp post 1 is sleeved with a first mounting shell 3 and a second mounting shell 4 respectively. One side of the first mounting shell 3 is attached to one side of the second mounting shell 4. A tooth disc 5 is fixedly connected to the side surface of the lamp post 1. A card slot 9 is provided on the side surface of the lamp post 1. A first rotating mechanism is arranged inside the second mounting shell 4, and a second rotating mechanism is arranged inside the first mounting shell 3.

[0024] The first rotating mechanism includes a first support plate 6. The first support plate 6 is fixedly connected to the inner wall of the second mounting shell 4. A first motor 7 is fixedly connected to the top of the first support plate 6. The output end of the first motor 7 extends to the bottom of the first support plate 6 and is fixedly connected with a gear 8. The gear 8 meshes with the tooth disc 5.

[0025] Snap rings 10 are fixedly connected to both the first mounting shell 3 and the second mounting shell 4. An auxiliary movement groove 11 is provided on the inner wall of the snap ring 10. A number of support rods are fixedly connected to the inner wall of the auxiliary movement groove 11. The side surface of each support rod is rotatably connected with a drum 12. The side surface of each drum 12 is attached to the inner wall of the card slot 9.

[0026] When the stadium light is in use, the first mounting shell 3 and the second mounting shell 4 need to be mounted on the lamp post 1. Then, the first motor 7 is connected to an external controller. When the first motor 7 is started through the external controller, the output end of the first motor 7 can drive the gear 8 to rotate. Since the gear 8 meshes with the toothed disc 5, and the toothed disc 5 is fixed on the lamp post 1, and the lamp post 1 is mounted on the ground through the mounting base 2, therefore, the first mounting shell 3, the second mounting shell 4 and the parts inside them can rotate around the lamp post 1 as the axis, thus realizing the adjustment of the irradiation angle of the stadium light. During the rotation of the first mounting shell 3 and the second mounting shell 4, the roller 12 will also rotate in a self-rotating manner on the side surface of the support rod to assist their rotation due to the influence of friction, effectively reducing the friction when the first mounting shell 3 and the second mounting shell 4 rotate, and improving the smoothness when the first mounting shell 3 and the second mounting shell 4 rotate.

[0027] Furthermore, in order to enable the connecting strip 20 to drive the lamp panel 22 to rotate, as Figure 1 , Figure 3 and Figure 5 shown, the second rotating mechanism includes a second support plate 13, the second support plate 13 is fixedly connected to the inner wall of the first mounting shell 3, a support block 15 is fixedly connected to the bottom of the second support plate 13, a rotating shaft 16 is rotatably connected to the support block 15, and a connecting strip 20 is fixedly connected to the side surface of the rotating shaft 16.

[0028] The second rotating mechanism further includes a bracket 19, the top of the bracket 19 is fixedly connected to the bottom of the second support plate 13, a worm 18 is rotatably connected inside the bracket 19, a second motor 14 is fixedly connected to the top of the second support plate 13, the output end of the second motor 14 penetrates through the second support plate 13 and is fixedly connected to the top end of the worm 18, a worm gear 17 is fixedly connected to the side surface of the rotating shaft 16, and the worm gear 17 meshes with the worm 18.

[0029] A through groove 21 is opened on one side of the first mounting shell 3 away from the second mounting shell 4, and one end of the connecting strip 20 away from the rotating shaft 16 extends to the outside of the first mounting shell 3 through the through groove 21 and is fixedly connected to a lamp panel 22.

[0030] A plurality of LED lamp beads are evenly distributed on the lamp panel 22 for providing illumination. When it is necessary to adjust the irradiation angle of the lamp panel 22, the second motor 14 can be started. The second motor 14 can drive the worm 18 to rotate. The setting of the bracket 19 provides guarantee for the stable rotation of the worm 18. Since the worm 18 meshes with the worm gear 17, when the worm 18 rotates, it can drive the worm gear 17 and the rotating shaft 16 fixedly connected thereto to rotate. When the rotating shaft 16 rotates, it can drive the connecting strip 20 and the lamp panel 22 to rotate around the rotating shaft 16 as the axis. The opening of the through groove 21 provides a rotating space for the connecting strip 20, thus realizing the adjustment of the irradiation angle of the lamp panel 22.

[0031] Furthermore, to facilitate the installation of the first mounting shell 3 and the second mounting shell 4 by the staff, as Figure 1 , Figure 2 and Figure 4 shown, connecting columns 24 are fixedly connected to both the top and bottom of the first mounting shell 3, and clamping plates 23 are rotatably connected to both the top and bottom of the second mounting shell 4. A bayonet 25 adapted to the connecting column 24 is formed on the clamping plate 23.

[0032] The same connecting plates are provided on both sides of the first mounting shell 3 and the second mounting shell 4, and fixing holes are provided on the connecting plates. When installing the first mounting shell 3 and the second mounting shell 4 on the lamp post 1, it is necessary to align the first mounting shell 3 and the second mounting shell 4 with each other, and then rotate the clamping plate 23 so that the bayonet 25 on the clamping plate 23 hooks the connecting column 24, so that the first mounting shell 3 and the second mounting shell 4 are connected together, facilitating the staff to subsequently use bolts to pass through the fixing holes on the connecting plates to reinforce the first mounting shell 3 and the second mounting shell 4.

[0033] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
