[0036] Examples, such as Figure 1-Figure 6As shown, a lamp angle adjustment and orientation structure includes a lamp holder 10 and a mounting bracket 20, with a rotating gear disc 30 fixedly connected on both sides of the lamp holder 10, and a threaded connection hole 31 and an indicating scale 32 are coaxially provided on the rotating gear disc 30; a non-rotating gear disc 40 capable of engaging with the rotating gear disc 30 is fixedly connected on the side of the mounting bracket 20 close to the lamp holder 10, and a pointer 41 matching with the indicating scale 32 is provided on the non-rotating gear disc 40 for indicating the projection direction of the lamp holder 10; a connecting through hole 21 matching with the threaded connection hole 31 is provided on the mounting bracket 20, and a fastening bolt 50 is provided in the connecting through hole 21, and the threaded end of the fastening bolt 50 is threadedly connected in the threaded connection hole 31, so that the rotating gear disc 30 and the non-rotating gear disc 40 are engaged with each other to prevent the lamp holder 10 and the mounting bracket 20 from rotating relative to each other.

[0037] In the present application, a follow-rotating gear plate 30 is fixedly connected to both sides of the lamp holder 10, and a non-rotating gear plate 40 is fixedly connected to the mounting bracket 20, and a fastening bolt 50 passed through the connecting through hole 21 of the mounting bracket 20 is threadedly connected to the follow-rotating gear plate 30 to achieve axial positioning and meshing connection between the follow-rotating gear plate 30 and the non-rotating gear plate 40, which can not only prevent the lamp holder 10 and the mounting bracket 20 from relative rotation and improve stability, but also after loosening the fastening bolt 50, the rotation angle of the lamp holder 10 relative to the mounting bracket 20 can be accurately adjusted through the relative rotation of the follow-rotating gear plate 30 and the non-rotating gear plate 40, thereby achieving accurate adjustment of the projection direction of the lamp holder 10.

[0038] In a specific embodiment, if Figure 3 As shown, the anti-rotation gear plate 40 and the mounting bracket 20 are detachably fixedly connected.

[0039] This arrangement is because: the anti-rotation gear plate 40 and the mounting bracket 20 are detachably fixedly connected, which not only facilitates the processing of the second teeth 43 on the anti-rotation gear plate 40, but also facilitates the replacement of the anti-rotation gear plate 40 on the mounting bracket 20, thereby improving the versatility of the mounting bracket 20.

[0040] Preferably, Figure 3 , Figure 5 and Figure 6 As shown, a plurality of threaded through holes 42 are distributed on the anti-rotation gear disk 40, and the plurality of threaded through holes 42 are evenly distributed around the axis of the anti-rotation gear disk 40; a countersunk hole 22 matching the threaded through hole 42 is provided on the mounting bracket 20, and a connecting screw 60 is provided in the countersunk hole 22, and the end of the connecting screw 60 is threadedly connected in the threaded through hole 42, and the end face of the connecting screw 60 is coplanar with the outer side face of the mounting bracket 20.

[0041] Specifically, Figure 5 and Figure 6As shown, four threaded through holes are formed on the anti-rotation gear disc 40, and the four threaded through holes 42 are evenly distributed around the axis of the anti-rotation gear disc 40; two countersunk holes 22 are formed on the mounting bracket 20, and the two countersunk holes 22 are symmetrically arranged on both sides of the connecting through hole 21.

[0042] It should be noted that a center hole 44 is coaxially provided on the anti-rotation gear plate 40 , and the center hole 44 is coaxial with the connecting through hole 21 on the mounting bracket 20 , and the radial dimension of the connecting through hole 21 is equal to the radial dimension of the center hole 44 .

[0043] More preferably, Figure 2 and Figure 3 As shown, an anti-loosening flat gasket 70 is provided between the nut end of the fastening bolt 50 and the mounting bracket 20. The anti-loosening flat gasket 70 is sleeved on the fastening bolt 50, and the radial dimension of the anti-loosening flat gasket 70 is larger than the spacing between the two countersunk holes 22, so that the anti-loosening flat gasket 70 can be pressed against the end face of the connecting screw 60 to prevent the connecting screw 60 from falling off.

[0044] More preferably, Figure 2 and Figure 3 As shown, a spring washer 80 is provided between the anti-loosening flat washer 70 and the nut end of the fastening bolt 50. The spring washer 80 is sleeved on the fastening bolt 50 and is used to apply axial elastic force to the fastening bolt 50 to improve the meshing effect of the rotating gear disc 30 and the anti-rotation gear disc 40.

[0045] In a specific embodiment, if Figure 1 and Figure 6 As shown, the mounting bracket 20 is a U-shaped bracket.

[0046] In a specific embodiment, if Figure 2 , Figure 5 and Figure 6 As shown, the follow-rotating gear plate 30 is integrally formed on both sides of the lamp holder 10 , and 72 first teeth 33 are evenly distributed circumferentially on the end face of the follow-rotating gear plate 30 away from the lamp holder 10 , and 72 second teeth 43 are evenly distributed circumferentially on the end face of the anti-rotating gear plate 40 .

[0047] The working process of adjusting the directional structure of this application is as follows:

[0048] In the present application, a follow-rotating gear disc 30 is installed on both sides of the lamp holder 10, and 72 serrated first teeth 33 are arranged in a circular array on the follow-rotating gear disc 30. A stop-rotation gear disc 40 is installed on the inner side of the mounting bracket 20, and 72 serrated second teeth 43 are arranged in a circular array on the stop-rotation gear disc 40 (the number of the first teeth 33 and the second teeth 43 is related to the angle interval that needs to be adjusted), and the interval between two adjacent first teeth 33 or second teeth 43 is 5 degrees.

[0049] There are four threaded through holes 42 evenly distributed on the circumference of the anti-rotation gear disc 40. The anti-rotation gear disc 40 is first fixed to the mounting bracket 20 by connecting screws 60, and then the mounting bracket 20 is fixed to the lamp holder 10 by fastening bolts 50, and the rotating gear disc 30 and the anti-rotation gear disc 40 are meshed with each other.

[0050] A pointer 41 is formed on the outer circumferential surface of the anti-rotation gear disc 40. The initial state of the lamp head 10 is that the light-emitting surface is horizontal and points to 0 degrees. The upward angle corresponds to the scale line of the rotating gear disc 30, realizing accurate positioning of the pointer 41.

[0051] Compared with the prior art, this application has at least the following beneficial technical effects:

[0052] 1) The up and down angles of the lamp can be accurately adjusted, and the structure is simple and easy to produce.

[0053] 2) The structure is simple, the parts are physically connected, there is no gap in the middle, and it can withstand greater locking force.

[0054] 3) The anti-rotation gears on both sides of the lamp holder are the same, which simplifies the specifications of parts, and the pointers on both sides of the lamp holder are symmetrically set to facilitate checking the adjustment angle of the lamp.

[0055] 4) The anti-loosening flat gasket can tighten the connecting screws between the anti-rotation gear plate and the mounting bracket to prevent them from falling off.

[0056] 5) The pointer accurately locates the light projection direction, and the 0 degree angle is in the vertical direction of the light-emitting surface, which is more beautiful.

[0057] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
