[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 5 As shown, this utility model provides a quick-disassembly positioning structure for an optical path, including a dark chamber body 1. A cover plate 11 is rotatably provided on one side of the dark chamber body 1, and a handle 12 is fixedly provided on one side of the cover plate 11. The handle 12 can be used to easily open and close the cover plate 11, facilitating the operation and maintenance of the internal structure. A mounting block 2 is detachably provided inside the dark chamber body 1, and an aperture body 3 is detachably provided on one side of the mounting block 2. A retaining ring 31 is fixedly provided on one side of the aperture body 3. An annular groove 21 for cooperating with the retaining ring 31 is opened on one side of the mounting block 2. Matching grooves 26 for cooperating with the aperture body 3 are opened on both sides of the dark chamber body 1. The detachable mounting block 2 inside the dark chamber body 1 is used to support the aperture body 3. The aperture body 3 is initially installed and positioned by cooperating with the annular groove 21 opened on one side of the mounting block 2 through the retaining ring 31 fixed on one side.

[0018] Specifically, the lower inner wall of the darkroom body 1 is provided with a columnar pre-reserved groove 24, and the lower inner wall of the columnar pre-reserved groove 24 is provided with a pre-reserved block groove 25. The lower surface of the aperture body 3 is fixedly provided with an insertion post 22, and the lower end of the insertion post 22 is engaged in the columnar pre-reserved groove 24. The lower surface of the insertion post 22 is fixedly provided with a positioning horizontal block 23, and the positioning horizontal block 23 is engaged in the pre-reserved block groove 25. The insertion post 22 fixed on the lower surface of the aperture body 3 is engaged in the columnar pre-reserved groove 24 opened in the lower inner wall of the darkroom body 1, and the positioning horizontal block 23 fixed on the lower surface of the insertion post 22 is engaged in the pre-reserved block groove 25 in the lower inner wall of the columnar pre-reserved groove 24. Through the multiple positioning structure, the precise position of the aperture body 3 in the optical path is ensured. In addition, the mating grooves 26 opened on both sides of the darkroom body 1 are adapted to the aperture body 3, further assisting in the positioning and stability of the aperture body 3.

[0019] Furthermore, a rotating seat 13 is symmetrically fixed to the upper part of one side of the darkroom body 1 by bolts, and a connecting seat 14 is symmetrically fixed to one side of the cover plate 11. The connecting seat 14 is rotatably mounted on the corresponding rotating seat 13. The cover plate 11 is rotatably connected to the rotating seat 13 symmetrically fixed to the upper part of one side of the darkroom body 1 by bolts through the connecting seat 14 symmetrically fixed to one side.

[0020] Furthermore, the outer surface of the mounting block 2 is symmetrically provided with anti-slip grooves 27. The anti-slip grooves 27 symmetrically provided on the outer surface of the mounting block 2 make it easier for operators to apply force when installing or removing the mounting block 2, thus improving the ease of operation.

[0021] It is worth noting that several bolt mounting slots 5 are provided on both sides of the darkroom body 1. The bolt mounting slots 5 provided on both sides of the darkroom body 1 are used to fix the entire structure to the external equipment to ensure the stability of the whole structure during operation.

[0022] It is worth noting that the lower parts of both sides of the darkroom body 1 are detachably provided with side boxes 4. The outer surface of the side boxes 4 is threaded with three connecting bolts 42, and the inner end of the connecting bolts 42 is threaded through the darkroom body 1. The darkroom body 1 is provided with symmetrical positioning grooves 44 on both sides. The upper surface of the side boxes 4 is fixed with a retaining strip 43, and the retaining strip 43 is engaged in the corresponding positioning groove 44. The side boxes 4 at the lower parts of both sides of the darkroom body 1 are engaged in the positioning grooves 44 symmetrically opened on both sides of the darkroom body 1 by the retaining strip 43 fixed on the upper surface, and are then firmly connected by the three connecting bolts 42 with threads through the outer surface (the inner end of the bolts is threaded through the darkroom body 1). The side boxes 4 can be used to store auxiliary components or enhance the overall structural stability.

[0023] Working principle: The quick-disassembly positioning structure for the optical path uses the darkroom body 1 as the basic carrier. The cover plate 11 is rotatably connected to the upper part of the darkroom body 1 by a symmetrically fixed connecting seat 14 on one side and a symmetrically fixed rotating seat 13 on the upper part of one side of the darkroom body 1 (the rotating seat 13 is fixed to the darkroom body 1 by bolts). The cover plate 11 can be easily opened and closed with the help of the handle 12, which facilitates the operation and maintenance of the internal structure. The mounting block 2, which is detachably installed inside the darkroom body 1, is used to support the aperture body 3. The aperture body 3 is initially installed and positioned by engaging with the annular groove 21 on one side of the mounting block 2 through a retaining ring 31 fixed on one side. At the same time, the insertion post 22 fixed on the lower surface of the aperture body 3 is engaged in the columnar reserved groove 24 opened in the lower inner wall of the darkroom body 1, and the positioning horizontal block 23 fixed on the lower surface of the insertion post 22 is engaged in the reserved block groove 25 on the lower inner wall of the columnar reserved groove 24. Through the multiple positioning structure, the precise position of the aperture body 3 in the optical path is ensured. In addition, the mating grooves 26 opened on both sides of the darkroom body 1 are adapted to the aperture body 3, further assisting in the positioning and stability of the aperture body 3. The anti-slip grooves 27 symmetrically formed on the outer surface of the mounting block 2 facilitate the application of force by the operator when installing or removing the mounting block 2, improving operational convenience. The side boxes 4 at the lower sides of the anechoic chamber body 1 are secured in the symmetrically formed positioning grooves 44 on both sides of the anechoic chamber body 1 by clips 43 fixed to the upper surface, and then firmly connected by three connecting bolts 42 with threads penetrating the outer surface (the inner ends of the bolts penetrate the anechoic chamber body 1). The side boxes 4 can be used to store auxiliary components or enhance the overall structural stability. In addition, several bolt mounting grooves 5 on both sides of the anechoic chamber body 1 are used to fix the entire structure to external equipment, ensuring overall stability during operation.
