[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Reference Figures 1 to 4 As shown, the present invention provides a visual star guiding device for a solar science telescope, comprising

[0030] The fixing base 1 has a light-transmitting screen 18 fixedly connected to one end of the top, and the light-transmitting screen 18 is arranged vertically;

[0031] An adjustable reference device is movably arranged at the other end of the top of the fixing base 1, and the adjustable reference device is adjusted with the center of the light-transmitting screen 18 as a reference;

[0032] The clamping device is detachably connected to the fixing seat 1, and the clamping device and the fixing seat 1 are used to fix the telescope therebetween;

[0033] The elastic clamping device is arranged on the clamping device and is used to fix the telescope at the center of the clamping device so that the adjustable reference device is parallel to the axis of the telescope.

[0034] By combining the provided clamping device with the fixing seat 1, the two can be stably fixed on the telescope barrel, providing guiding assistance for the process of aiming the telescope at the sun. The provided elastic clamping device can adjust the size of the central space after the clamping device is combined with the fixing seat 1, so that the entire device can adapt to telescopes with different barrel sizes, thereby improving the versatility of the device. The provided adjustable reference device can adjust its own three-dimensional spatial position so that it can coincide with the central axis of the light-transmitting screen 18 to ensure the guiding assistance effect.

[0035] Furthermore, the interior of the fixed seat 1 is hollow, and a through hole 11 is opened on the top wall of the fixed seat 1. The adjustable reference device includes a first adjusting rod 12, and the outer side wall of the first adjusting rod 12 is provided with a thread. The first adjusting rod 12 is rotatably set inside the fixed seat 1, and one end of the first adjusting rod 12 located outside the fixed seat 1 is fixedly connected to two first ears 13. The outer side wall of the first adjusting rod 12 located inside the fixed seat 1 is threadedly connected to a slider 14, and the slider 14 is slidably set in the through hole 11. The top of the slider 14 is fixedly connected to an adjustable reference part, and the adjustable reference part is in sliding contact with the top of the fixed seat 1.

[0036] Furthermore, the adjustable reference part includes a fixed frame 15, which is fixedly connected to the top of the slider 14, and the fixed frame 15 is in sliding contact with the top of the fixed seat 1. Two position adjustment parts are arranged on the side wall of the fixed frame 15, and the two position adjustment parts are perpendicular to each other. A shading plate 27 is movably arranged in the center of the two position adjustment parts, and a sight 28 is arranged in the center of the shading plate 27.

[0037] The distance between the shading plate 27 and the light-transmitting screen 18 can be adjusted by setting the first adjusting rod 12. During adjustment, the first adjusting rod 12 is rotated forward or reversely to drive the slider 14 to move toward or away from the light-transmitting screen 18, thereby adjusting the distance between the shading plate 27 and the light-transmitting screen 18.

[0038] The shading plate 27 is made of white translucent material, and the surface is frosted, which can reduce mirror reflection and facilitate observation of the position of the bright spot in the front and rear directions.

[0039] Furthermore, the position adjustment portion includes a spiral driving portion and an elastic contact portion, and the spiral driving portion and the elastic contact portion are respectively disposed on two opposite side walls of the shading plate 27 in contact with each other.

[0040] Furthermore, the spiral drive unit includes a second adjusting rod 16, which is threadedly connected to the side wall of the fixed frame 15, and one end of the second adjusting rod 16 located outside the fixed frame 15 is fixedly connected to two second ears 17, and one end of the second adjusting rod 16 located inside the fixed frame 15 is fixedly connected to a first strip plate 29, and two first fixed seats 30 are respectively fixedly connected to the two ends of the side wall of the first strip plate 29 close to the shading plate 27, and a first rolling ball 31 is rotatably arranged between the two first fixed seats 30 located at the same end, and the first rolling ball 31 is rollingly arranged in a groove 32 opened on the side wall of the shading plate 27.

[0041] Furthermore, the elastic contact portion includes two third sleeves 33, and the two third sleeves 33 are fixedly arranged on the inner wall of the fixed frame 15 at intervals. A third slide rod 34 is slidably arranged inside the third sleeve 33, and the two third slide rods 34 are located at one end outside the third sleeve 33 and are commonly fixedly connected to a second strip plate 36. Two second fixed seats 37 are respectively fixedly connected to the two ends of the side wall of the second strip plate 36 close to the shading plate 27, and a second ball 38 is rotatably arranged between the two second fixed seats 37 located at the same end. The second ball 38 is rollingly arranged in a groove 32 opened on the side wall of the shading plate 27, and a third spring 35 is sleeved on the outer side of the third slide rod 34. The two ends of the third spring 35 are respectively fixedly connected to the third sleeve 33 and the second strip plate 36.

[0042] After the distance between the shading plate 27 and the light-transmitting screen 18 is adjusted to a suitable position, the horizontal position and the height position of the shading plate 27 in the vertical plane can be adjusted by the two second adjusting rods 16. The adjustment principle and process of the horizontal position and the height position are the same. Taking the adjustment of the height position as an example, the position of the first strip plate 29 in the height direction can be adjusted by rotating the second adjusting rod 16. When the first strip plate 29 descends in the height direction, the shading plate 27 is pressed downward, and at the same time, the shading plate 27 compresses the third spring 35 downward, so that the downward position of the shading plate 27 and the front sight 28 can be adjusted. When the second adjusting rod 16 is rotated in the opposite direction, the third spring 35 is restored. The light shielding plate 27 is lifted upward according to its own length, so that the upward position of the light shielding plate 27 and the front sight 28 can be adjusted. When the height position of the light shielding plate 27 is adjusted, the first rolling ball 31 and the second rolling ball 38 in the horizontal position can roll freely in the groove 32 of the vertical side wall of the light shielding plate 27, which can ensure the stable adjustment of the height direction of the light shielding plate 27 and will not change the position in the horizontal direction. The horizontal position and height position of the light shielding plate 27 can be adjusted at the same time or separately. Due to the existence of the first rolling ball 31, the second rolling ball 38 and the groove 32, there will be no interference in the process of simultaneous adjustment or separate adjustment.

[0043] Furthermore, the clamping device includes a center plate 23, and the two relatively long side walls of the center plate 23 are respectively rotatably connected to the V-shaped connecting rod 2, and the end of the V-shaped connecting rod 2 away from the center plate 23 is detachably connected to the side wall of the fixed seat 1, and the elastic clamping device includes a second elastic clamping part and two first elastic clamping parts, the second elastic clamping part is threadedly connected to the center plate 23, the first elastic clamping part corresponds one-to-one to the V-shaped connecting rod 2, and the first elastic clamping part is threadedly connected to the middle part of the V-shaped connecting rod 2.

[0044] As an embodiment that can be added to the present invention, two relatively long side walls of the center plate 23 are respectively fixedly connected to two second positioning blocks 24, and the two second positioning blocks 24 are arranged at intervals. One end of the V-shaped connecting rod 2 is fixedly connected to a second connecting block 25, and the second connecting block 25 is located between the two second positioning blocks 24 and the three rotate together and are penetrated by a second connecting shaft 26. The relative rotation of the V-shaped connecting rod 2 and the center plate 23 can be achieved by the arranged second positioning block 24, the second connecting block 25 and the second connecting shaft 26.

[0045] The other end of the V-shaped connecting rod 2 is fixedly connected to a first connecting block 21, and the side wall of the fixed seat 1 is fixedly connected to two first positioning blocks 20, the two first positioning blocks 20 are arranged at an interval, the first connecting block 21 is located between the two first positioning blocks 20 and the three are detachably penetrated by a first connecting shaft 22, and the detachable connection between the V-shaped connecting rod 2 and the fixed seat 1 can be achieved by setting the first positioning block 20, the first connecting block 21 and the first connecting shaft 22.

[0046] Furthermore, the first elastic clamping part includes a first sleeve 3, the outer wall of the first sleeve 3 is provided with a thread and is threadedly connected to the middle part of the V-shaped connecting rod 2, a first slide rod 4 is slidably arranged inside the first sleeve 3, one end of the first slide rod 4 located outside the first sleeve 3 is fixedly connected to the first top plate 6, a first spring 5 is sleeved on the outside of the first slide rod 4, and both ends of the first spring 5 are respectively fixedly connected to the end of the first sleeve 3 and the first top plate 6.

[0047] Another second elastic clamping portion is also arranged at the center of the bottom end of the fixing seat 1 .

[0048] Furthermore, the second elastic clamping part includes a second sleeve 7, the outer wall of the second sleeve 7 is provided with a thread and is threadedly connected to the center plate 23, a second slide rod 8 is slidably arranged inside the second sleeve 7, one end of the second slide rod 8 located outside the second sleeve 7 is fixedly connected to the second top plate 10, and a second spring 9 is sleeved on the outside of the second slide rod 8, and both ends of the second spring 9 are respectively fixedly connected to the end of the second sleeve 7 and the second top plate 10.

[0049] Furthermore, a center hole 19 is opened in the center of the light-transmitting screen 18 .

[0050] The surfaces of all parts of the guide device except the sunshade 27 are spray-painted black to prevent reflected light from causing damage to the eyes.

[0051] The working process of the present invention is as follows:

[0052] Before installing on the telescope, the fixing seat 1 and the V-shaped connecting rod 2 are separated. First, the fixing seat 1 and the center plate 23 are placed above and below the lens barrel respectively, so that the two second top plates 10 are both against the outside of the lens barrel. Then, the free ends of the two V-shaped connecting rods 2 are fixed to the two sides of the fixing seat 1 by the first connecting shaft 22 respectively. In this way, the initial fixation of the device on the telescope is completed. Then, the positions of the first sleeve 3 and the second sleeve 7 are adjusted according to the size of the lens barrel of the telescope. When the size of the lens barrel is small, the first sleeve 3 and the second sleeve 7 are screwed in the direction close to the lens barrel. The positions of the tube 3 and the second sleeve 7 make the first top plate 6 and the second top plate 10 both abut against the outside of the lens barrel and provide a certain clamping force. When the size of the lens barrel is large, the positions of the first sleeve 3 and the second sleeve 7 are spirally adjusted in the direction away from the lens barrel, so that the first top plate 6 and the second top plate 10 both abut against the outside of the lens barrel and provide a certain clamping force. After the device is completely fixed on the lens barrel, the relative positions of the shading plate 27 and the light-transmitting screen 18 are adjusted by the first adjusting rod 12 and the two second adjusting rods 16. After the adjustment, the telescope can be assisted to aim at the sun.
