[0003] According to a Chinese patent publication numbered CN208653493U, a large-caliber starlight simulator is disclosed. In the patent, the contact area between the positioning bolt and the support frame is increased by the support plate to prevent the support frame from being unable to adjust the tightness of the support frame during support, resulting in the support frame being unable to support the starlight simulation body. The positioning block is used to further increase the tightness of the support frame during rotation to prevent the support frame from being too loose or too tight, affecting the movement of the support frame. The limiting bolt is used to allow the positioning rod to rotate in different directions.

[0004] In actual use, although the above-mentioned existing structure realizes the rotation of different angles and height adjustment of the starlight simulator, it still has certain limitations in use, that is, the height adjustment of the starlight simulator is realized by cross-arranged support rods in this structure, but the adjustment range is small, and it is limited by the length of the support rods during use. When the length of the support rods increases, the overall support stability will be affected. At the same time, it is difficult to install starlight simulators of different sizes in this document, and the overall scope of application is small. Utility Model Content

[0026] In this embodiment, compared with the installation method in the prior art, the utility model can adjust the clamping stroke according to the size and shape of the star simulator body 5 to ensure the stability and adaptability of the installation; star simulator bodies 5 of different sizes can be flexibly clamped and installed by adjusting the clamping stroke of the clamping assembly 4, and star simulator bodies 5 of different sizes can be easily replaced in specific use, and it is also convenient to maintain and clean the star simulator body 5;

[0027] Furthermore, through the installation between the slider seat 33 and the clamping assembly 4, the clamping assembly 4 can be precisely adjusted in height, thereby realizing the height adjustment of the star simulator body 5; compared with the manual height adjustment method, the use of the height adjustment assembly 3 can save a lot of time and energy, making the height adjustment more convenient and efficient. At the same time, the height adjustment assembly 3 set up can also realize the large stroke height control of the star simulator body 5, so as to meet specific needs. The precise height control between the screw rod 32 and the slider seat 33 can improve the height accuracy and reliability of the star simulator body 5, and ensure that the star simulator body 5 can accurately simulate the position and movement of the target.

[0028] Specifically, refer to Figure 3-4 The clamping plates 45 are arranged in an arc shape, and the whole material is made of rubber. The clamping plates 45 are arranged in a circular shape as a whole, and anti-slip patterns are arranged on the inner wall surface.

[0029] In this embodiment, in actual use, when the clamping plate 45 is set to achieve the surrounding clamping of the star simulator body 5, the anti-slip texture arranged inside the clamping plate 45 can ensure the clamping stability of the star simulator body 5. At the same time, the clamping plate 45 is made of rubber as a whole, so that when the clamping plate 45 surrounds the star simulator body 5, it can avoid scratches or damage to the surface of the star simulator body 5. In addition, the rubber clamping plate 45 can also provide shockproof and vibration-proof functions, reducing the impact of external vibrations on the star simulator body 5.

[0030] Specifically, refer to Figure 3-4 A reciprocating reduction motor is installed in the motor seat 41 , and the output end of the reciprocating reduction motor passes through the positioning plate 42 and is connected to a transmission shaft 46 , and a rotating gear plate 47 is sleeved on the outside of the transmission shaft 46 .

[0031] In this embodiment, in actual use, the user can drive the reciprocating reduction motor located in the motor seat 41 to rotate, by connecting the reciprocating reduction motor to a power source and driving the transmission shaft 46 to rotate through the motor, so that the set transmission shaft 46 can drive the rotating gear plate 47 to rotate as a whole.

[0032] Specifically, refer to Figure 3-4 A plurality of rotary grooves 48 are formed around the center of the rotating gear disc 47 ; a rotary column 49 is integrally connected to the end of each support arm 44 , and the plurality of rotary columns 49 correspond to the rotary grooves 48 in sequence and slide in the rotary grooves 48 .

At this time, when the rotating toothed disc 47 rotates, the plurality of support arms 44 provided can move radially along the center of the transmission shaft 46; in a preferred embodiment, as Figure 3 As shown in, when the rotating toothed disc 47 rotates in a clockwise direction, the several clamping plates 45 that are set perform a circular expansion motion. At this time, the clamping plates 45 that are set are separated by a distance, and thus are adapted to the installation and positioning of a large-caliber star simulator body 5. Compared with the installation method in the prior art, the new type completes the installation of the star simulator body 5 by using clamping, and the overall installation is more convenient, and the disassembly and assembly are convenient, and the star simulator body 5 is easy to repair and disassemble; when the rotating toothed disc 47 rotates counterclockwise, the several clamping plates 45 that are set perform a circular contraction motion. At this time, the clamping plates 45 that are set can adapt to the installation of a smaller-sized star simulator body 5.

[0034] Specifically, refer to Figure 3-4 A matching gear 410 is rotatably provided on the side of the positioning plate 42 , and the matching gear 410 is meshed with the rotating gear plate 47 .

[0035] In this embodiment, during use, the matching gear 410 can better enable the positioning disk 42 to rotate stably, avoiding shaking and deviation of the positioning disk 42 during rotation, and at the same time, when the positioning disk 42 rotates, the plurality of rotating pillars 49 sliding on the positioning disk 42 can slide stably.

[0036] Specifically, refer to Figure 1-2The height adjustment assembly 3 also includes two side limit rods 34 arranged on the reciprocating motor 31, and the two side limit rods 34 are respectively arranged on one side of the screw rod 32. The two side limit rods 34 both penetrate the slider seat 33 and are slidably connected to the screw rod 32; a plurality of universal wheels 2 are also assembled on the base frame 1.

[0037] In this embodiment, when adjusting the height adjustment component 3, the user connects a power source to the reciprocating motor 31 so that the reciprocating motor 31 can drive the screw rod 32 to rotate. When the screw rod 32 rotates, it is laterally limited by two side limit rods 34, so that the slider seat 33 can move in a straight line within the stroke range of the screw rod 32. Through the installation between the slider seat 33 and the clamping component 4, the clamping component 4 can be precisely height-adjusted, thereby realizing the height adjustment of the star simulator body 5; further, in a preferred embodiment, a plurality of clamping components 4 arranged on the base frame 1 can enable the base frame 1 to move flexibly, thereby allowing the star simulator body 5 installed on the base frame 1 to move freely in the use space, thereby improving the scope of use and flexibility of the present application.

[0038] The dynamic adjustment mechanism for the star simulator of the utility model:

[0039] Step 1: In actual use, when the user needs to install the star simulator body 5, the user places the star simulator body 5 between several clamping plates 45, and then drives the reciprocating reduction motor located in the motor seat 41. At this time, the motor drives the transmission shaft 46 to rotate, so that the set transmission shaft 46 can drive the rotating gear plate 47 to rotate as a whole. When the rotating gear plate 47 rotates, it is limited by the sliding between the rotation groove 48 and the rotation column 49, and cooperates with the linear sliding limit of the support arm 44 by the slide groove 43. At this time, when the rotating gear plate 47 rotates, the several support arms 44 set can move radially along the center of the transmission shaft 46; Step 2: The user controls the radial movement of the clamping plates 45, and makes the several clamping plates 45 surround and clamp the star simulator body 5. At this time, the set star simulator body 5 can be clamped and assembled on the clamping component 4; Step 3: When the star simulator body 5 is assembled, the user can drive the height adjustment component 3 to operate. By connecting the reciprocating motor 31 to a power source, the reciprocating motor 31 can drive the screw rod 32 to rotate. When the screw rod 32 rotates, it is laterally limited by two side limit rods 34, so that the slider seat 33 can move in a straight line within the travel range of the screw rod 32. Through the installation between the slider seat 33 and the clamping component 4, the clamping component 4 can be precisely adjusted in height, thereby realizing the height adjustment of the star simulator body 5.
