[0028] As Figures 1-5 shown, a grating component that can form the character pattern of "Five Blessings" according to the present disclosure may include a substrate 1. A connecting block 11 is fixedly connected to the bottom end of the substrate 1, and a bottom plate 12 is fixedly connected to the bottom end of the connecting block 11;

[0029] On one side of the top end of the substrate 1, a fixed plate 13 is fixedly connected. A moving plate 2 is slidably connected to the top end of the substrate 1, and a laser emitter 3 is arranged on the side of the moving plate 2 away from the fixed plate 13;

[0030] A connecting plate 41 is slidably connected to the inner side of the bottom plate 12. A fixing block 4 is fixedly connected to the end of the connecting plate 41. A grating mounting bracket 7 is fixedly connected to the top of the fixing block 4. An insertion slot 73 is formed at the top of the grating mounting bracket 7. A diffractive optical grating 6 is arranged inside the insertion slot 73.

[0031] Therefore, by providing a laser emitter 3, the laser emitter 3 and the grating mounting bracket 7 are on the same horizontal line, so that the light from the laser emitter 3 can pass through the grating mounting bracket 7 and irradiate on the diffractive optical grating 6. The diffractive optical grating 6 is a double-sided structure. One of the structural surfaces is processed into a grating phase structure that can form an image of a one-dimensional five-point splitting light field after irradiation, and the other side is processed into a grating phase structure that can form an image of a blessing character light field after irradiation. The structural surfaces are all relief-type micro-topographies. Under the irradiation of the laser emitter 3, a complete diffractive light field of the five blessings arriving at the door pattern is formed in the front according to the imaging principle. The micro-topography structural surface of the diffractive optical grating 6 is a diffractive grating optical element based on Fraunhofer diffraction. By providing the laser emitter 3 and irradiating the diffractive optical grating 6, a complete diffractive light field of the five blessings arriving at the door pattern can be generated. The laser emitter 3 can be adjusted in the front and rear positions. At the same time, the grating mounting bracket 7 used to mount the diffractive optical grating 6 can also move back and forth, so as to change the irradiation distance between the laser emitter 3 and the diffractive optical grating 6, thereby effectively changing the size of the diffractive light field of the five blessings arriving at the door pattern generated by the laser emitter 3 irradiating the diffractive optical grating 6, effectively improving the use effect of the device. A power supply is arranged at the rear end of the laser emitter 3, which can directly supply power to the laser emitter 3;

[0032] As Figure 4 shown, in a preferred embodiment, through holes 72 are formed on both the left and right sides of the top of the grating mounting bracket 7. Second side ears 71 are fixedly connected to both the front and rear ends of the grating mounting bracket 7. First side ears 61 are fixedly connected to both the front and rear ends of the diffractive optical grating 6. The first side ears 61 and the second side ears 71 are arranged correspondingly.

[0033] Therefore, by providing the through holes 72, it is convenient for the light from the laser emitter 3 to be set to enter the diffractive optical grating 6 inside the grating mounting bracket 7 and irradiate out from the through hole 72 at the other end. By providing the first side ears 61 and the second side ears 71, through holes are arranged inside them, so that it is convenient to fix the first side ear 61 on the top of the second side ear 71 by using bolts, that is, effectively fixing the diffractive optical grating 6 in the insertion slot 73, and at the same time facilitating the replacement of the diffractive optical grating 6.

[0034] As Figure 5As shown in this disclosure, a slider 411 is fixedly connected to the bottom end of the connecting plate 41 relative to the other end of the fixed block 4. A slide plate 412 is fixedly connected to the bottom end of the slider 411. A fastening bolt 8 is provided on the inner side of the slide plate 412. A groove 122 is opened in the middle of the bottom end of the base plate 12. The slider 411 is slidably connected to the inner side of the groove 122.

[0035] Therefore, the slide plate 412 is set at the bottom end of the base plate 12. A groove 122 is opened in the middle of the bottom end of the base plate 12, so that the slider 411 slides in the groove 122. A threaded hole corresponding to the fastening bolt 8 is opened on the inner side of the slide plate 412 away from the middle, so that the fastening bolt 8 can rotate in the thread. When it is necessary to limit and fix the slide plate 412, the fastening bolt 8 can be tightened in the slide plate 412 and the bottom end of the base plate 12 can be pressed, thereby limiting the slide plate 412, that is, limiting the connecting plate 41 and the fixing block 4.

[0036] like Figure 3 As shown, in a preferred embodiment, a second mounting block 31 is fixedly connected to the bottom end of the laser emitter 3. The laser emitter 3 is fixedly connected to the side of the movable plate 2 through the second mounting block 31. A through groove 131 is provided in the middle of both the fixed plate 13 and the movable plate 2. The laser emitter 3 passes through the fixed plate 13 and the movable plate 2.

[0037] Therefore, by setting a second mounting block 31, a through hole is provided in the middle of the second mounting block 31, which is convenient to fix the second mounting block 31 to the side of the moving plate 2 with bolts, thus effectively installing and fixing the laser emitter 3. A through groove 131 is provided in the middle of both the fixed plate 13 and the moving plate 2, which is convenient to accurately irradiate the laser emitter 3.

[0038] like Figure 2 and Figure 3 As shown in this disclosure, a first groove 14 is provided at the top of the substrate 1, a stop block 15 is fixedly connected to one side of the first groove 14, a threaded post 5 is threadedly connected to the inner side of the stop block 15, the threaded post 5 is rotatably disposed inside the first groove 14, and a threaded block 21 is fixedly connected to the bottom of the movable plate 2, the threaded post 5 and the threaded block 21 are threadedly connected.

[0039] Therefore, by setting the first slide groove 14, the threaded block 21 can be slidably connected to the inner side of the first slide groove 14. The middle part of the stop block 15 is provided with a through hole corresponding to the threaded post 5, so that the threaded post 5 can be rotatably connected to the inner side of the stop block 15. The threaded post 5 is rotatably set in the first slide groove 14. The middle part of the threaded block 21 is provided with a threaded hole and is threadedly connected to the threaded post 5. Thus, rotating the fixed block 4 can drive the threaded block 21 to move inside the first slide groove 14. The laser emitter 3 is fixed to the moving plate 2, so that it can be used to drive the moving plate 2 to move. The threaded block 21 is provided on the outside of one end of the threaded post 5. The threaded post 5 and the threaded block 21 will be regularly cleaned and lubricated to reduce the impact of dust intrusion between the threaded post 5 and the threaded block 21.

[0040] In practical use, by setting the first mounting block 121, a through hole is opened in the middle of the first mounting block 121, so that the first mounting block 121 can be fixed on the bracket with bolts. The laser emitter 3 is inserted into the inner side of the moving plate 2 and the fixed plate 13 respectively. The second mounting block 31 is set and fixed to the side of the moving plate 2 with bolts.

[0041] Insert the diffraction optical grating 6 into the insertion slot 73, and use bolts to fix the first side ear 61 to the top of the second side ear 71;

[0042] Depending on the irradiation distance and the size of the image, the distance between the laser emitter 3 and the grating mounting bracket 7 is adjusted. Rotating the threaded column 5 can drive the threaded block 21 to move, thereby driving the moving plate 2 to move, and finally driving the laser emitter 3 to move, thus facilitating the adjustment of the laser emitter 3's position.

[0043] Move the sliding plate 412 to move the connecting plate 41, thereby moving the fixing block 4 and the grating mounting frame 7 fixed at the top of the fixing block 4. This makes it easier to move the grating mounting frame 7. After the position is determined, tighten the fastening bolt 8 to press the bottom end of the base plate 12 to fix the position of the connecting plate 41, the fixing block 4 and the grating mounting frame 7.

[0044] The laser emitter 3 is activated to illuminate the diffraction optical grating 6, forming a complete five-blessing pattern diffraction light field in front of it according to the imaging principle.

Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
