Technical Field
[0001] The utility model relates to the technical field of lamps, and in particular to a rotating structure for adjusting the angle of a lamp. Background Art

Whether it is the exterior lighting of large buildings, the embellishment of urban landscapes, or the lighting needs of stages and stadiums, floodlights can provide just the right lighting effect for these scenes with their high brightness and adjustable beam angles.
[0003] The structure of a floodlight usually includes components such as a light source, a reflector, a radiator, and a rotating mechanism. Among them, the light source is the core of the floodlight and is responsible for emitting light; the reflector is used to gather and direct the light to ensure that it can irradiate in a predetermined direction; the radiator is responsible for dissipating the heat generated by the light source to ensure the stable operation of the floodlight; and the rotating mechanism allows the user to adjust the irradiation angle of the floodlight as needed.
[0004] In addition, there are some problems in the use of the rotating mechanism:
[0005] First, when the rotating mechanism rotates frequently, its internal bearings, gears and other parts are prone to wear due to friction. This wear will reduce the accuracy and stability of the rotating mechanism and may also affect the overall service life of the floodlight. In addition, as the use time increases, the wear problem may gradually increase, resulting in a decrease in the lighting effect of the floodlight or even failure.
[0006] Secondly, in addition to the wear problem, the accuracy of the rotation angle is also an aspect that needs to be paid attention to in the rotation mechanism of the floodlight. Specifically, due to the influence of the manufacturing process, installation accuracy and the use environment, the rotation angle of the floodlight is sometimes difficult to achieve precise control, which may cause the irradiation direction of the floodlight to deviate from the actual needs, affecting the uniformity and consistency of the lighting effect. Especially in some scenes with high requirements for lighting effects, such as stage performances, sports competitions, etc., the problem of rotation angle accuracy may be more obvious.

[0025] The present invention is further described below in conjunction with the accompanying drawings and implementation modes:
[0026] It should be noted that a floodlight is a lamp with a long irradiation distance, which means that during the lighting process, a small angle rotation and adjustment of the floodlight at the light source will cause a large displacement of the target light source. This means that during the use of the floodlight, its rotation mechanism has a greater impact on the use of the floodlight. Combined with the existing defects mentioned in the background technology, this application proposes a rotating structure for adjusting the angle of the lamp.
[0027] See also Figure 1-4The utility model proposes a rotating structure for adjusting the angle of a lamp, including a lamp body 100 and a rotating mechanism 200, wherein the rotating mechanism 200 includes a coarse adjustment part 10 and a fine adjustment part 20, wherein the coarse adjustment part 10 includes a first bracket 11 connected to the lamp body 100, and a second bracket 12, wherein the first bracket 11 and the second bracket 12 are connected to a rotation axis and are used to coarsely adjust the angle of the irradiation direction of the lamp body 100; wherein the fine adjustment part 20 includes a first end 21 abutting against the first bracket 11 and connected to the lamp body 100, and a second end 22, wherein the first end 21 and the second end 22 are connected to a rotation axis and are meshingly engaged and abutted, and are used to finely adjust the irradiation direction of the lamp body 100.

It can be understood that the first end 21 is located on the inner side of the first bracket 11, and the first end 21 of the first bracket 11 is connected and fixed to the bottom of the lamp body 100 to form an integral structure. The second end 22 is externally connected to a fixing device, and combined with the second bracket 12 externally connected to a fixing device, the first bracket 11 is flipped and rotated relative to the second bracket 12, thereby driving the lamp body 100 to perform a coarse adjustment flip. In addition, after the coarse adjustment angle flip is completed, the first end 21 is flipped and rotated relative to the second end 22, thereby driving the lamp body 100 to perform a fine adjustment rotation, so that through the structural settings of the fine adjustment part 20 and the coarse adjustment part 10, the lamp body 100 is coarsely adjusted and finely adjusted in turn, thereby improving the rotation accuracy and stability of the lamp body 100.
[0029] For further information, see Figure 2-4The coarse adjustment member 10 also includes a bolt shaft 13. The first bracket 11 and the second bracket 12 are both provided with mutually adapted shaft holes 131. The bolt shaft 13 passes through the shaft holes 131 to clamp and fix the first bracket 11 and the second bracket 12.

The bolt shaft 13 is arranged through the shaft hole 131, so that the first bracket 11 and the second bracket 12 are clamped by the bolt shaft 13, thereby improving the stability of the abutting structure between the two.
[0031] For further information, see Figure 2-4 The coarse adjustment member 10 also includes a coarse adjustment bolt 14. The first bracket 11 is provided with a plurality of coarse adjustment holes 111. The second bracket 12 is provided with an adjustment auxiliary hole 121 adapted to the coarse adjustment hole 111. The coarse adjustment bolt 14 passes through the coarse adjustment hole 111 and the adjustment auxiliary hole 121 in sequence to clamp and fix the first bracket 11 and the second bracket 12. The coarse adjustment bolt 14 is used to clamp and fix the relative position of the first bracket 11 and the second bracket 12.
[0032] For further information, see Figure 2-3 , a plurality of the coarse adjustment holes 111 are arranged in an arc shape at equal intervals around the rotating shaft hole 131 , and a plurality of the coarse adjustment holes 111 are arranged around the axis of the rotating shaft hole 131 .
[0033] In this embodiment, the coarse adjustment part 10 includes two coarse adjustment bolts 14, which can also be bolts. Specifically, a plurality of coarse adjustment holes 111 are provided on the two wings of the first bracket 11 at equal intervals around the corresponding rotating shaft hole 131, and the plurality of coarse adjustment holes 111 are arranged in an arc shape with the coarse adjustment hole 111 as the center. In addition, the two wings of the second bracket 12 are provided with corresponding auxiliary adjustment holes 121. By flipping the first bracket 11, the first end 21 and the lamp body 100 and rotating them around the coarse bolt axis 13, the auxiliary adjustment hole 121 is made to correspond to any coarse adjustment hole 111 to obtain the desired flipping angle. Combined with the coarse adjustment bolt 14 passing through the coarse adjustment hole 111 and the auxiliary adjustment hole 121, the first bracket 11 and the second bracket 12 are clamped and fixed.
[0034] In some embodiments, see Figure 3 , some of the coarse adjustment holes 111 are arc-shaped grooves 112, and the arc-shaped grooves 112 are arranged around the axis of the rotating shaft hole 131.
[0035] In this embodiment, a plurality of coarse adjustment holes 111 are connected to form an arc groove 112, and the arc groove 112 is arranged around the axis of the rotating shaft hole 131, so that by loosening the coarse adjustment bolt 14, the lamp body 100 can be rotated by flipping the first bracket 11, and the structural setting of the arc groove 112 can select more rotation angles.

The first end 21 is provided with a fixing screw hole 211 that matches the fine-tuning hole 221. The fine-tuning screw 24 passes through the fine-tuning hole 221 and is threadedly installed in the fixing screw hole 211. The fine-tuning screw 24 is used to clamp the first end 21 and the second end 22.
[0038] In this embodiment, the fine-tuning screw 24 passes through the fine-tuning hole 221 and is threadedly installed in the fixing screw hole 211. Through the structural setting of the fine-tuning screw 24 combined with the fixing screw hole 211, the first end 21 and the second end 22 can be meshingly connected, so that the first end 21 is flipped relative to the bolt shaft 13 to perform a small rotation, thereby achieving fine-tuning of the illumination direction of the lamp body 100.
[0039] It should be explained that the diameters of the auxiliary adjustment hole 121 and the coarse adjustment hole 111 are both larger than the diameter of the coarse adjustment bolt 14, so that after coarse adjustment, the first end 21 can still be turned over and rotated around the bolt axis 13 for further fine adjustment.
