[0024] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.
[0025] like Figure 1 As shown, as a dustproof optical adjustment frame of the utility model, it includes a bracket 1, a driving motor 11 is fixed on the bracket 1, an output end of the driving motor 11 is connected to a driving gear 12, and a connecting rod 22 is rotatably provided on the bracket 1. Figure 2 As shown, support plates 2 are fixed at both ends of the connecting rod 22, and driven gears 21 meshing with the driving gear 12 are fixed at the ends of the connecting rod 22. The driving motor 11 drives the driving gear 12 to rotate, thereby driving the driven gear 21 to rotate and then driving the support plate 2 to adjust the angle. The stability of the angle adjustment is improved by gear meshing, avoiding angle deviation caused by gravity and other factors.
[0026] A bidirectional motor 34 is provided in the middle of the support plate 2. Figure 3 As shown, both ends of the bidirectional motor 34 are transmission-connected with a threaded rod 35, and a threaded block 33 is threadedly arranged on the threaded rod 35. The two threaded blocks 33 are symmetrically arranged, and the ends of the two threaded blocks 33 are respectively fixed with a first clamping plate 31 and a second clamping plate 32. The first clamping plate 31 and the second clamping plate 32 are both slidably connected to the support plate 2. The bidirectional motor 34 drives the threaded rod 35 to rotate, thereby driving the two threaded blocks 33 to move in the opposite direction on the threaded rod 35. The movement of the threaded block 33 drives the first clamping plate 31 and the second clamping plate 32 to move, thereby driving the first clamping plate 31 and the second clamping plate 32 to move in the opposite direction through the driving mechanism composed of the bidirectional motor 34, the threaded rod 35 and the threaded block 33, and then the optical device is clamped through the limiting mechanism 3 composed of the driving mechanism, the first clamping plate 31 and the second clamping plate 32.
[0027] A limiting plate 4 is fixed to one end of the facing surfaces of the first clamping plate 31 and the second clamping plate 32. Figure 4 As shown, a plug plate 5 is fixed to the other end of the first clamping plate 31 facing the side of the second clamping plate 32. Figure 5As shown, a fixing plate 7 is fixed on one end of the second clamping plate 32 facing the side of the first clamping plate 31 corresponding to the plugging plate 5, and a groove for inserting the plugging plate 5 is provided on the fixing plate 7, a sponge plate 6 is fixed on one end of the plugging plate 5 close to the limiting plate 4, and the thickness of the plugging plate 5 is less than the thickness of the groove, the surface of the plugging plate 5 away from the limiting plate 4 is in contact with the groove, and the surface of the sponge plate 6 close to the limiting plate 4 is located on the same plane as the surface of the fixing plate 7 close to the limiting plate 4 under normal conditions;
[0028] One side of the optical device is limited by the limiting plate 4, and the other side of the optical device is limited by the plug plate 5 and the fixing plate 7, while the optical device is shielded to prevent dust from entering the optical device, thereby extending the service life of the optical device. At the same time, the sponge plate 6 is used to make the optical device contact with the sponge plate 6 and the fixing plate 7 at the same time, avoiding dust from entering due to the gap caused by the plugging of the plug plate 5 and the fixing plate 7, thereby improving the dust isolation effect and further ensuring the service life of the optical device.
[0029] like Figure 3 As shown, the first clamping plate 31 and the second clamping plate 32 are both configured as arc-shaped clamping plates, and the limiting plate 4 is completely located inside the first clamping plate 31 and the second clamping plate 32. Compared with the square clamping plate, the arc-shaped clamping plate can improve the clamping effect on the optical device through the arc-shaped portion of the arc-shaped clamping plate, thereby preventing the optical device from being displaced due to gravity. The limiting plate 4 is completely located inside the arc-shaped clamping plate to ensure that the limiting plate 4 will not affect the contact between the first clamping plate 31 and the second clamping plate 32, thereby ensuring that more optical devices can be clamped, thereby increasing the scope of application.
[0030] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
