Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-3 , this embodiment provides a technical solution: a laser structure and a spotlight applying this structure, including a laser chamber 1 and a focal length adjustment mechanism 4;

[0022] Laser chamber 1: A laser generator 3 is arranged inside it. The input end of the laser generator 3 is electrically connected to the output end of an external controller.

The output end of the beam splitter 11 is electrically connected to the input end of the laser generator 3. The input end of the beam splitter 11 is electrically connected to the output end of an external controller;

[0023] Focus adjustment mechanism 4: It includes an adjustment cylinder 41, a limit ring 42, a sliding groove 43 and a locking block 46. The adjustment cylinder 41 is threadedly connected to the lower end of the laser chamber 1. The middle of the inner wall of the adjustment cylinder 41 is fixedly connected with the limit ring 42. The lower end of the inner wall of the adjustment cylinder 41 is provided with evenly distributed sliding grooves 43. The inside of the sliding grooves 43 are all slidably connected with locking blocks 46. A lens 5 is arranged between the four locking blocks 46 and the limit ring 42. The focus adjustment mechanism 4 further includes guide posts 44. The guide posts 44 are all fixedly connected to the inside of the sliding grooves 43. The inside of the locking blocks 46 are all provided with sliding openings. The outer surfaces of the guide posts 44 are all slidably connected to the inside of the laterally adjacent sliding openings. The lengths of the guide posts 44 are all less than the lengths of the sliding grooves 43. The focus adjustment mechanism 4 further includes springs 45. The springs 45 are all fixedly connected between the locking blocks 46 and the laterally adjacent sliding grooves 43. The springs 45 are all movably sleeved on the outer surfaces of the laterally adjacent guide posts 44. The ends of the locking blocks 46 away from the laser chamber 1 are all provided with arc surfaces. The upper end of the adjustment cylinder 41 is fixedly connected with evenly distributed support plates 7. The upper ends of the support plates 7 are all fixedly connected with the lower end of the indicating ring 8. The middle of the outer surface of the laser chamber 1 is provided with evenly distributed scale bars 9. The scale bars 9 are all installed in cooperation with the indicating ring 8. Select a lens 5 of the corresponding specification according to the beam divergence requirement, and then push the lens 5 into the inside of the adjustment cylinder 41 from bottom to top. When the lens 5 contacts the arc surfaces of the four locking blocks 46, the lens 5 pushes the four locking blocks 46 to move away from the center of the adjustment cylinder 41 in the corresponding laterally adjacent sliding grooves 43 under the guiding action of the corresponding guide posts 44. At the same time, the locking blocks 46 all elastically compress the laterally adjacent springs 45. When the upper surface of the lens 5 contacts the lower surface of the limit ring 42, the lens 5 ends the thrust on the locking blocks 46. The springs 45 all push the corresponding locking blocks 43 to reset. The locking blocks 46 cooperate with the limit ring 43 to work, realizing the clamping and fixing of the lens 5, and realizing the quick replacement and locking of the lens 5. Then, according to the focal length requirement of the lens 5, rotate the adjustment cylinder 41. The adjustment cylinder 41 moves downward under the action of the laser chamber 1. At the same time, according to the information provided by the cooperation of the indicating ring 8 and the scale bar 9, the position adjustment of the lens 5 is realized. When the lens 5 reaches the required position, stop rotating the adjustment cylinder 41, so that the lens 5 reaches the required focal length, realizing the quick adjustment of the beam divergence degree;

[0024] Among them: The upper end of the laser chamber 1 is threadedly connected with an installation chamber 2. The upper end of the installation chamber 2 is fixedly connected with a connecting ring 12. A hanging rope 13 is arranged inside the connecting ring 12.

[0025] The working principle of a laser structure provided by the present utility model and a spot lamp applying this structure is as follows: During operation, the operator selects a lens 5 of the corresponding specification according to the beam divergence requirement, and then pushes the lens 5 into the interior of the adjusting cylinder 41 from bottom to top. When the lens 5 contacts the arc surfaces of the four locking blocks 46, the lens 5 pushes the four locking blocks 46 to move away from the center of the adjusting cylinder 41 in the laterally adjacent sliding grooves 43 under the guiding action of the corresponding guiding columns 44. At the same time, the locking blocks 46 elastically compress the laterally adjacent springs 45. When the upper surface of the lens 5 contacts the lower surface of the limiting ring 42, the lens 5 ends the pushing force on the locking blocks 46, and the springs 45 push the corresponding locking blocks 43 to reset. The locking blocks 46 cooperate with the limiting ring 43 to work, realizing the clamping and fixing of the lens 5, and enabling the rapid replacement and locking of the lens 5. Then, according to the focal length requirement of the lens 5, the adjusting cylinder 41 is rotated. The adjusting cylinder 41 moves downward under the action of the laser chamber 1. At the same time, according to the information provided by the cooperation of the indicating ring 8 and the scale bar 9, the position adjustment of the lens 5 is realized. When the lens 5 reaches the required position, the rotation of the adjusting cylinder 41 is stopped, so that the lens 5 reaches the required focal length, realizing the rapid adjustment of the beam divergence degree, and thus meeting the beam projection requirement of the working environment. Then, the operator stably connects the mounting holes inside the mounting plate 14 with the threaded holes in the working area through bolts, thereby realizing the stable installation of the laser structure and the spot lamp applying this structure. After the installation is completed, the operator holds the laser structure and the spot lamp applying this structure through the hanging rope 13, and realizes the angle adjustment of the laser chamber 1 and the mounting chamber 2, thereby realizing the projection angle adjustment of the laser structure and the spot lamp applying this structure. When the laser chamber 1 reaches the required angle, the rotation of the mounting chamber 2 is stopped. Then, the laser generator 3 is operated through an external controller. The laser generator 3 emits a beam, which is dispersed by the lens 5 and projected onto a specified area. The operator can operate the beam distributor 11 through the external controller to adjust the characteristics such as the color and shape of the beam.

[0026] It should be noted that the methods for controlling the laser generator 3 and the beam distributor 11 by the external controller disclosed in the above embodiments are all commonly used methods in the prior art.

[0027] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
