[0035] As Figure 4 shown, in a further embodiment, at least one group of threaded holes 111 is provided on the side of the cylinder body 11. The adjustment assembly 14 includes at least one elastic member 142 and at least two adjustment screws 141. The elastic member 142 is installed between the inner wall of the cylinder body 11 and the outer wall of the hole seat 16. The elastic member 142 and the threaded holes 111 are arranged on the cylinder body 11 in a circumferential arrangement. The adjustment screws 141 are matched with the threaded holes 111. One end of the adjustment screw 141 passing through the threaded hole 111 abuts against the side of the hole seat 16, and the end of the adjustment screw 141 located outside the cylinder body 11 is used to adjust the position of the adjustment screw 141 inside the cylinder body 11.
[0036] Among them, through the cooperation between the elastic member 142 and the adjustment screws 141 and the threaded holes 111, the hole seat 16 can be installed inside the cylinder body 11. By rotating the adjustment screw 141, the position of the adjustment screw 141 inside the cylinder is changed, and then the position of the hole seat 16 is adjusted. To achieve more stable and accurate adjustment, a larger number of adjustment screws 141 and threaded holes 111 can be provided.
[0037] AsFigure 5 As shown, an installation groove 112 is provided on the inner wall of the cylinder body 11. One end of the elastic member 142 is installed in the installation groove 112, and the other end abuts against the outer wall of the hole seat 16. The elastic member 142 includes an elastic plate 1421 which is installed on the installation groove 112, and the top of the elastic plate 1421 abuts against the outer wall of the hole seat 16. The elastic member 142 also includes a spring 1422 which is installed in the installation groove 112, and the top of the spring 1422 abuts against the outer wall of the hole seat 16.
[0038] In an embodiment of the present utility model, the light guide plate 12 and the hole seat 16 inside the cylinder body 11 can also be fixedly installed, and the projection screen 15 can be set to be adjustable. An adjustment assembly 14 is provided at a position corresponding to the projection screen 15 on the cylinder body 11 to adjust the position of the projection screen; when using the sun finder, the position of the hole seat 16 relative to the cylinder body 11 is adjusted through the adjustment assembly 14, so that after the sunlight passes through the axial hole of the hole seat 16, the light spot can irradiate the center of the projection screen 15.
[0039] In a further embodiment, the sun finder further includes an installation assembly 13. The installation assembly 13 includes a fitting 131 and a fixing member 132. Among them, there are two fittings 131 which are symmetrically installed on the side surface of the cylinder body 11. An assembly groove 1311 is provided on the inner side of the fitting 131, and the assembly groove 1311 cooperates with the assembly block on the sun observation mirror 2; one end of the fixing member 132 is installed on one set of fittings 131, and the other end is installed on the other set of fittings 131.
[0040] The present utility model also provides a sun observation mirror, and the sun observation mirror 2 includes the above-mentioned sun finder.
[0041] When in use, first ensure that the center of the field of view of the sun observation mirror 2 coincides with the sun light source. By rotating the adjustment nut 141 on the adjustment assembly 14, the position of the axial hole of the hole seat 16 relative to the cylinder body 11 is adjusted, so that the sunlight can irradiate the center position of the projection screen 15 after passing through the light guide hole 121 and the axial hole in sequence. At this time, the optical axis of the sun finder 1 coincides with the optical axis of the sun observation mirror 2; when using the sun observation mirror 2 to observe the sun next time, the sun can be found through the sun finder 1. As long as the sun light source is in the center of the field of view of the sun finder 1, then the sun light source is also in the center of the field of view of the sun observation mirror 2; if in the sun finder 1, the hole seat 16 is fixedly installed and the projection screen 15 is adjustable, then by adjusting the adjustment assembly 14, the center position of the projection screen 15 is changed to ensure that the light spot of the sunlight entering the cylinder body 11 can irradiate on the center position of the projection screen 15, so as to ensure that the optical axis of the sun finder 1 coincides with the optical axis of the sun observation mirror 2.
[0042] In the solar target finder 1 and the solar observation mirror 2 of the present utility model, the relative position of the hole seat 16 with respect to the center of the projection screen 15 can be adjusted through the adjusting assembly 14. When the adjusting assembly 14 is adjusted so that the axial hole of the hole seat 16 is located at the center position of the projection screen 15, the optical axis of the solar target finder 1 is parallel to the optical axis of the solar light measuring mirror 2. Then, the solar target finder 2 can be used to find the position of the sun, and the solar light measuring mirror 2 can be used to observe the sun. Compared with the prior art, the present utility model is more flexible in use, has lower requirements for the production accuracy and assembly accuracy of the equipment, and thus reduces the production cost.
