[0032] Although the present application can be readily implemented in various embodiments, only some of the specific embodiments are illustrated in the drawings and described in detail in the present specification, and it should be understood that the present specification should be considered as a demonstrative explanation of the principles of the present application, and is not intended to limit the present application to what is described herein.

[0033] Therefore, one feature indicated in the present specification will be used to explain one feature of one embodiment of the present application, and is not intended to imply that each embodiment of the present application must have the explained feature. In addition, it should be noted that the present specification describes many features. Although certain features can be combined together to show possible system designs, these features can also be used in other combinations which are not explicitly explained. Therefore, unless otherwise specified, the explained combinations are not intended to be limiting.

[0034] ​​​In the embodiments shown in the drawings, the indications of directions, such as up, down, left, right, front and back, are used to explain the structure and movement of various elements of the present application, which are not absolute but relative. When these elements are in the positions shown in the drawings, these descriptions are appropriate. If the positions of these elements change, the indications of directions also change accordingly.

[0035] Referring to Figure 1 to Figure 5 The simple grating tower structure provided by the embodiment of the present application mainly comprises a grating support 1, a grating 2 and an adjusting assembly 3. The grating support 1 comprises a first plate body 11, a second plate body 12, a first elastic member 13 and a second elastic member 14. The first plate body 11 and the second plate body 12 are arranged in a vertical direction. The first elastic member 13 and the second elastic member 14 are distributed in a first horizontal direction D1 and are connected between the first plate body 11 and the second plate body 12. The grating 2 is located above the grating support 1 and is connected with the second plate body 12. The adjusting assembly 3 is located between the first elastic member 13 and the second elastic member 14 and is close to the first elastic member 13 or close to the second elastic member 14. The adjusting assembly 3 comprises two adjusting members 31. The two adjusting members 31 are symmetrically distributed on both sides of the first elastic member 13 and the second elastic member 14 in a second horizontal direction D2. The second horizontal direction D2 is perpendicular to the first horizontal direction D1. The adjusting member 31 comprises an axially connected rod part 311 and a cap part 312. The rod part 311 penetrates through the second plate body 12 and is screwed with the first plate body 11. The cap part 312 is located above the second plate body 12 to block the second plate body 12 from being pulled out of the rod part 311 upwardly.

[0036] In the simple grating tower structure of the embodiment of the present application, an elastic support structure can be formed between the first plate body 11, the second plate body 12, the first elastic member 13 and the second elastic member 14, so that the second plate body 12 is kept horizontally stable in an initial state. Since the rod part 311 of the adjusting member 31 is screwed with the first plate body 11, rotating the adjusting member 31 can make the rod part 311 move along the side of the first plate body 11 into which the rod part 311 is screwed or out of which the rod part 311 is screwed. When the rod part 311 moves along the side of the first plate body 11 into which the rod part 311 is screwed, the cap part 312 presses the second plate body 12 downwardly, and the first elastic member 13 and the second elastic member 14 are compressed and deformed to accumulate elastic force. When the rod part 311 moves along the side of the first plate body 11 out of which the rod part 311 is screwed, the cap part 312 rises with the rod part 311, and the elastic force of the first elastic member 13 and the second elastic member 14 is used to drive the second plate body 12 to reset.

[0037] When only one of the adjustment members 31 is rotated, the compression deformation of the first elastic member 13 and the second elastic member 14 mainly occurs on the side close to the adjustment member 31 in the second horizontal direction D2, so that the second plate body 12 is tilted downward on the side where the adjustment member 31 is located in the second horizontal direction D2, thereby fine-tuning the inclination angle of the grating 2 on the second plate body 12 in the second horizontal direction D2. When both adjustment members 31 are rotated and the depths at which the rod portions 311 of the two adjustment members 31 are screwed into the first plate body 11 are the same, because the adjustment assembly 3 is close to the first elastic member 13 or the second elastic member 14, and the first elastic member 13 and the second elastic member 14 are spaced apart in the first horizontal direction D1, according to the specific arrangement, the deformation of the elastic member close to the adjustment assembly 3 is larger, so that the second plate body 12 can be tilted downward on the side where the elastic member is located in the first horizontal direction D1, thereby fine-tuning the inclination angle of the grating 2 on the second plate body 12 in the first horizontal direction D1. The first elastic member 13 and the second elastic member 14 can also ensure the stability of the second plate body 12 during adjustment, so that after the adjustment members 31 are rotated, the second plate body 12 and the grating 2 on the second plate body 12 can be kept at the adjusted inclination angle. In summary, the simple grating tower structure can fine-tune the inclination angle of the grating 2 in the first horizontal direction D1 and the second horizontal direction D2, thereby being applicable to scenarios that require multi-dimensional dynamic adjustment.

[0038] It should be noted that in specific use scenarios, the first horizontal direction D1 is the front-back direction, and the second horizontal direction D2 is the left-right direction.

[0039] It should be noted that when both adjustment members 31 are rotated and the depths at which the rod portions 311 of the two adjustment members 31 are screwed into the first plate body 11 are different, the fine-tuning of the inclination angle of the grating 2 in the second horizontal direction D2 can also be achieved, but compared with rotating a single adjustment member 31, the operation is more cumbersome and less stable.

[0040] In specific embodiments, the number of second plate bodies 12 is at least two, each second plate body 12 is arranged in sequence in the circumferential direction of the first plate body 11, the number of gratings 2 is the same as the number of second plate bodies 12, and each grating 2 corresponds to each second plate body 12 one-to-one. The plurality of gratings 2 can respectively process light rays incident from different directions, or process incident angle light rays of different waveband ranges, thereby expanding the functions of the simple grating tower structure.

[0041] In the present embodiment, the number of second plate bodies 12, first elastic members 13, second elastic members 14, adjustment assemblies 3 and gratings 2 is two, and the two second plate bodies 12 are arranged side by side in the first horizontal direction D1.

[0042] In a further embodiment, two second elastic members 14 are located within the interval of the two first elastic members 13 in the first horizontal direction D1, the adjusting assembly 3 is arranged close to the second elastic members 14, and the gratings 2 on the second plate body 12 are located on the side close to the first elastic members 13. Such arrangement is compact and reasonable, and can reduce the mutual interference of the gratings 2 on the two second plate bodies 12.

[0044] It should be noted that in the case that the grating support 1 on the grating base 4 is rotatable, the first horizontal direction D1 and the second horizontal direction D2 described in the above embodiments are not fixed directions, and are mainly used to indicate the positional relationship between the first elastic member 13, the second elastic member 14 and the two adjusting members 31 when the grating support 1 is in a certain direction.

The motor shaft of the rotary motor 53 passes through the clearance 511 and is connected with the input end of the speed reducer 52. The transition plate 51 is used to provide a stable connection basis for the rotary motor 53 and the speed reducer 52, so as to ensure that the motor shaft of the rotary motor 53 and the input end of the speed reducer 52 can be accurately aligned. The rotary motor 53 is used to provide a rotating force. After being reduced by the speed reducer 52, the rotary motor 53 and the speed reducer 52 can be cooperatively matched to reduce mechanical wear, prolong the service life of the grating 2 tower structure, and adapt to high-precision measurement requirements.
