Detailed ways

As shown in Figure 1-5, an LED floodlight with convenient angle adjustment includes a LED floodlight body 1, and the left and right sides of the LED floodlight body 1 are respectively provided with a support plate 4, and the lower end of the support plate 4 Both are provided with a mounting plate 20 . The upper end of the support plate 4 is hingedly connected with the LED floodlight body 1 through the rotating shaft 21, and the arc bar 3 coaxial with the rotating shaft 21 is arranged between the two support plates 4, and the back of the LED flood light body 1 is connected with the arc bar 3 One end of each is connected by a connecting rod 2, a plurality of teeth are evenly distributed on the left end surface of the arc bar 3, a first connecting plate 7 is arranged between the two supporting plates 4, and the vertical rotating rod 6 passes through the first connecting plate 7. The slotted hole 9 on the connecting plate 7, the rotating rod 6 is connected with the slotted hole 9 on the first connecting plate 7 through a bearing. The upper end of the rotating rod 6 is provided with a gear 5 meshing with the teeth on the left end surface of the arc bar 3, the lower part of the rotating rod 6 is provided with a rotating handle 8, and the lower end of the rotating rod 6 is provided with an upper turntable 10, and the lower end surface of the upper turntable 10 A hemispherical bump 11 is arranged on the top, and a second connecting plate 22 is arranged below the first connecting plate 7. The lifting rod 15 coaxial with the rotating rod 6 passes through the hole on the second connecting plate 22, and the lifting rod 15 The upper end of the lower turntable 12 is provided with its coaxial center, and the upper end surface of the lower turntable 12 is circularly arranged with a plurality of arc-shaped grooves 13 corresponding to the bumps 11, and the hole wall of the second connecting plate 22 is provided with There is a vertical chute 16, the vertical slide bar 17 on the outer edge of the elevating rod 15 is slidably matched with the chute 16, and the elevating rod 15 between the lower turntable 12 and the second connecting plate 22 is sleeved with a spring 14.
