[0035] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can imagine various embodiments of the present invention. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or limitation of the technical solution of the present invention. On the contrary, the purpose of providing these embodiments is to enable those skilled in the art to understand the present invention more thoroughly. The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the innovative concept of the present invention.

[0036] The present invention is conceived as a quick adjustment structure of a pointing system. By rationally designing the connection structure between the antenna and the center body, three-point quick adjustment of the antenna device is achieved. By designing an adjustment mechanism and adding a wedge-shaped gasket, two-axis quick adjustment of the laser TV is achieved. The adjustment mechanism of the telescope assembly is optimized to achieve two-axis quick adjustment of the telescope, thereby improving the testability of the equipment.

[0037] As an embodiment, a pointing system rapid adjustment structure, such as Figure 1 As shown, the antenna device 1 is arranged in front of the high-frequency box device 2, and the laser TV combination 3 is arranged on the side of the high-frequency box device 2. The antenna device 1 and the laser TV combination 3 can be quickly adjusted through the adjustment structure to meet the antenna pointing requirements.

[0038] like Figure 2 As shown, in a further embodiment, the antenna device 1 includes a feed source 1-1, a transition flange 1-2, a center body 1-3, an adjustment structure 1-4 and a parabolic antenna 1-5. The feed source 1-1 is connected to the center body 1-3 through the transition flange 1-2. The center body 1-3 is a central cylindrical body with three cantilever structures evenly distributed around it. The three cantilevers are respectively connected to the parabolic antenna 1-5 through the adjustment structure 1-4. Each adjustment structure 1-4 can adjust the distance between the center body 1-3 and the parabolic antenna 1-5.

[0039] like Figure 3As shown, in a further embodiment, the adjustment structure 1-4 includes an adjustment sleeve 1-4-1, an adjustment flange 1-4-2, an adjustment screw 1-4-3, a fixed flange 1-4-4 and a pressure block 1-4-5. The flange end face of the adjustment flange 1-4-2 is fixedly connected to the center body 1-3, and the other side of the flange end face is a sleeve-shaped structure, the outer surface of which is threadedly connected to the adjustment sleeve 1-4-1, and the inner surface is a light hole, and the adjustment screw 1-4-3 passes through the middle of the light hole. One end of the adjusting screw 1-4-3 is in the form of a hexagonal inner cavity guide hole, which cooperates with the fixing flange 1-4-4. The outer flange of the fixing flange 1-4-4 is fixedly connected to the central body 1-3. The middle hexagonal columnar guide pin cooperates with the hexagonal inner cavity guide hole of the adjusting screw 1-4-3, thereby limiting the circular rotation of the adjusting screw 1-4-3; the other end of the adjusting screw 1-4-3 is connected to the threaded hole of the mounting seat of the parabolic antenna 1-5. There is a boss on the mounting seat of the parabolic antenna 1-5, and the boss surface is in contact with the adjusting sleeve 1-4-1.

[0040] Furthermore, four clamping grooves are processed on one side of the cylinder of the adjustment sleeve 1-4-1, and a pair of clamping blocks 1-4-5 are installed on the outer periphery. When the clamping blocks 1-4-5 are tightened, the entire adjustment structure 1-4 can be clamped and fixed.

[0041] According to the test results of the parabolic antenna 1-5 and the feed source 1-1, when the position of the parabolic antenna 1-5 needs to be adjusted, first fix one adjustment structure 1-4, that is, tighten the corresponding pressure block 1-4-5, and then adjust the other two adjustment structures 1-4. The adjustment method is as follows: 1. When the distance between the parabolic antenna 1-5 and the center body 1-3 needs to be increased, loosen the pressure block 1-4-5 and loosen the adjustment sleeve 1-4-1. At this time, the adjustment sleeve 1-4-1 will push the boss surface of the parabolic antenna 1-5 mounting seat away from the center body 1-3. 3 Threaded connection, the hexagonal cavity of the adjustment screw 1-4-3 and the hexagonal columnar guide pin ligand of the fixing flange 1-4-4" make the center of the mounting seat of the parabolic antenna 1-5 not offset; 2 When it is necessary to reduce the distance between the parabolic antenna 1-5 and the center body 1-3, loosen the pressure block 1-4-5, tighten the adjustment sleeve 1-4-1, and the flange surface of the adjustment sleeve 1-4-1 will be close to the center body 1-3. Since the adjustment screw 1-4-3 is threadedly connected to the mounting seat of the parabolic antenna 1-5, the requirement of reducing the distance between the parabolic antenna 1-5 and the center body 1-3 can be achieved at this time. After the distance adjustment is completed, tighten the pressure block 1-4-5 to fix the entire adjustment structure 1-4.

[0042] It can be seen that this adjustment method only requires loosening the pressure block 1-4-5 and rotating the adjustment sleeve 1-4-1 to achieve the position adjustment of the parabolic antenna 1-5, and the method is simple and fast.

[0043] like Figure 4 As shown, in a further embodiment, the high-frequency box device 2 includes a high-frequency box shell 2-1, a pitch axis 12-2 and a pitch axis 22-3, one end of the pitch axis 12-2 and the pitch axis 22-3 are arranged on both sides of the high-frequency box shell 2-2, and the other end of the pitch axis 22-3 is installed with a laser TV combination 3, and the pitch rotation of the high-frequency box device 2 is achieved by applying power to the pitch axis 12-2 and the pitch axis 22-3.

[0044] like Figure 5 As shown, the laser TV assembly 3 includes a bracket 3-1, a wedge-shaped gasket 3-2, an adjustment mechanism 3-3, a flat gasket 3-4, a laser TV 3-5, a telescope assembly 3-6 and a screw 3-7. The bracket 3-1 is in an "L" shape as a whole. The laser TV 3-5, the flat gasket 3-4 and the wedge-shaped gasket 3-2 are arranged above the platform mounting surface of the bracket 3-1, the adjustment mechanism 3-3 is installed in the middle, and the telescope assembly 3-6 is installed below. The two sides of the bottom of the laser TV 3-5 are fixed to the bracket 3-1 through flat gaskets 3-4 and a pair of wedge-shaped gaskets 3-2 respectively, wherein the opening of the connecting part of the bracket 3-1 is a waist-shaped hole, and the flat gasket 3-4 and the pair of wedge-shaped gaskets 3-2 are slotted holes; the middle of the bottom of the laser TV 3-5 is connected to the bracket 3-1 through the adjustment mechanism 3-3.

[0045] like Figure 6 , Figure 7 As shown, the adjustment mechanism 3-3 is composed of a base 3-3-1, a bushing 3-3-2, a horizontal shaft 3-3-3, and a vertical shaft 3-3-4. The base 3-3-1 is fixed on the bracket 3-1, and a pair of bushings 3-3-2 are installed horizontally in the middle of the base 3-3-1. The bushing 3-3-2 is installed in cooperation with the horizontal shaft 3-3-3 cylinder. The horizontal shaft 3-3-3 has a cylindrical hole in the middle, which cooperates with the vertical shaft 3-3-4 cylinder and is fixed by a nut. The upper end surface of the vertical shaft 3-3-4 is fixed to the laser TV 3-5.

[0046] The adjustment method of laser TV 3-5 is as follows: 1. When the pitch angle of laser TV 3-5 needs to be adjusted, the thickness of the combination of a pair of wedge-shaped gaskets 3-2 can be increased or decreased by moving the wedge-shaped gasket 3-2 forward and backward. Since the position and thickness of the flat gasket 3-4 remain unchanged, the pitch angle adjustment of laser TV 3-5 can be achieved and adjusted. In this process, the bushing 3-3-2 in the adjustment mechanism 3-3 does not cooperate with the cylindrical surface of the horizontal axis 3-3-3, which will not cause the entire adjustment process to be stuck. 2. When the azimuth angle of laser TV 3-5 needs to be adjusted, first loosen the screws 3-7 at the flat gasket 3-4 and the wedge-shaped gasket 3-2, and then according to the azimuth test results, directly rotate the laser TV 3-5 slightly horizontally. When the azimuth angle requirements are met, tighten the screws 3-7 at the flat gasket 3-4 and the wedge-shaped gasket 3-2 to fix it. In this process, the horizontal axis 3-3-3 in the adjustment mechanism 3-3 cooperates with the vertical axis 3-3-4 cylinder to play a centering role.

[0047] It can be seen that this adjustment method only requires moving the wedge-shaped gasket 3-2 forward and backward to adjust the pitch angle of the laser TV 3-5, and only requires loosening the screws at the flat gasket 3-4 and the wedge-shaped gasket 3-2 and slightly rotating the laser TV 3-5 horizontally to adjust the azimuth angle of the laser TV 3-5. The method is simple and fast.

[0048] like Figure 8 As shown, the telescope assembly 3-6 consists of a telescope 3-6-1, a base plate 3-6-2, a base 3-6-3, a cushion block 3-6-4, an adjustment block 3-6-5, an azimuth pin screw 3-6-6, a pitch pin screw 3-6-7, an azimuth screw 3-6-8, a pitch screw 3-6-9, a bracket plate 3-6-10, and a pressure cover 3-6-11. The telescope 3-6-1 is fixedly mounted on the base plate 3-6-2 through two sets of bracket plates 3-6-10 and a pressure cover 3-6-11. The base plate 3-6-2 is positioned by a pitch pin screw 3-6-7 and fixed to the base 3-6-3 by four screws, wherein the base 3-6-3 is connected at a position with four waist-shaped holes. The base 3-6-3 is in an "L-shape", and the vertical surface of the "L-shape" is installed on the bottom plate 3-6-2. A pair of pitch screws 3-6-9 are installed on the bottom surface of the vertical surface through threaded holes. The pitch screws 3-6-9 are symmetrically installed and contact the adjustment block 3-6-5 installed on the bottom plate 3-6-2. When the pitch screws 3-6-9 are rotated, since the base 3-6-3 is fixedly installed on the bracket 3-1, the pitch screws 3-6-9 will drive the bottom plate 3-6-2 to rotate around the pitch pin screw 3-6-7, thereby realizing the pitch rotation of the telescope 3-6-1.

[0049] The upper end face of the "L-shaped" base 3-6-3 is positioned by the azimuth pin screw 3-6-6 and fixed to the bracket 3-1 by four screws, wherein the bracket 3-1 is fixed at four waist-shaped holes, and one side of the upper end face is equipped with a pair of azimuth screws 3-6-8 through threaded holes, and the azimuth screws 3-6-8 are symmetrically installed and contact the pad 3-6-4 installed on the bracket 3-1. When the azimuth screw 3-6-8 is rotated, since the pad 3-6-4 is fixed, the azimuth screw 3-6-8 will drive the base 3-6-3 to rotate around the azimuth pin screw 3-6-6, so as to realize the azimuth rotation of the telescope 3-6-1.

[0050] It can be seen that this adjustment method only requires rotating the pitch screw 3-6-9 and the azimuth screw 3-6-8 to adjust the azimuth pitch angle of the telescope assembly 3-1. The adjustment method is simple, convenient and fast.
