[0028] Example 1

[0029] See also Figure 1The embodiment of the utility model provides a detachable lens, a first lens barrel 100 and a fixed barrel 200; the fixed barrel 200 is sleeved on the outer surface of the first lens barrel 100. The first lens barrel 100, as a main structure, is used to install lenses, and a plurality of lens mounting grooves are provided inside thereof for installing different lenses, so that it can be adapted to a variety of photographic equipment. A combination of different focal lengths, apertures and lens types is selected for installation to achieve a variety of shooting effects. The fixed barrel 200 is provided on the outer surface of the first lens barrel 100, and can be installed through the fixed barrel 200 to fix the first lens barrel 100 for stable observation. The fixed barrel 200 is detachably provided on the first lens barrel 100 by a plurality of screws 111; the first lens barrel 100 is hollow inside and provided with a receiving space; the receiving space is provided with a plurality of lens mounting grooves.

[0030] See also Figure 2 The fixing barrel 200 is mounted on the upper end of the first lens barrel 100 by means of a plurality of detachable screws 111; a hollow space is reserved inside the first lens barrel 100, and a plurality of steps are provided in the space, which is sufficient to accommodate a plurality of lenses. The steps are provided to form a lens mounting groove, and the lens is installed through the lens mounting groove to ensure the stability and safety of the lens, and to make the structure of the entire lens barrel more compact and firm. The plurality of lens mounting grooves are not only a place to place the lens, but also a place to fix and adjust the lens, and their existence makes the installation and replacement of the lens simple and quick.

[0031] See also Figure 1 and Figure 4 The lens mounting groove includes a first mounting groove 120, a second mounting groove 130, a third mounting groove 140 and a fourth mounting groove 150; the first mounting groove 120, the second mounting groove 130, the third mounting groove 140 and the fourth mounting groove 150 are arranged from the observation end 190 to the direction of the light input end 180. The lens mounting groove inside the first lens barrel 100 is provided with at least four grooves. The first mounting groove 120 is used to install the basic observation lens, and extends inside it, and a plurality of lens mounting grooves are sequentially arranged, and a plurality of different lenses can be installed to achieve the adjustment of different focal lengths, apertures and lenses, and to achieve different effects of observation and shooting. By setting a plurality of lens mounting grooves, the lens can be easily replaced according to different shooting requirements and scenes to achieve the best shooting effect. The axis center lines of the first mounting groove 120, the second mounting groove 130, the third mounting groove 140, the fourth mounting groove 150, the fifth mounting groove 181 and the sixth mounting groove 182 are the same, that is, the coincidence of the optical axis can be guaranteed.

[0032] See also Figure 1The fourth installation groove 150 is a long groove; a lens auxiliary installation tube 160 and a lens stopper tube 170 are arranged in the fourth installation groove 150; a lens installation groove is arranged in the lens auxiliary installation tube 160; adjacent lenses are separated by the lens stopper tube 170. Such a layout not only allows adjacent lenses to be stably separated, but also allows them to maintain a proper distance from each other during the installation process, thus ensuring installation efficiency and quality.

[0033] Taking into account the installation requirements of lenses of different sizes, the fourth mounting groove 150 is designed as a through groove with a fixed diameter and a large length, so that lenses of various sizes can be accommodated. However, such a through groove alone is not enough to ensure the stability of the lens and the accuracy of installation. In order to solve this problem, a lens auxiliary mounting barrel 160 is introduced. The designed outer diameter of this barrel matches the fourth mounting groove 150, ensuring that it can be embedded in the groove perfectly. The internal structure of the lens auxiliary mounting barrel 160 includes a stepped lens mounting groove, so that lenses of different diameters can be adapted and fixed.

[0034] See also Figure 1 The two ends of the first lens barrel 100 are respectively a light-inlet end 180 and an observation end 190. The two ends of the first lens barrel 100 are respectively a light-inlet end 180 for light to enter and an observation end 190 for observation. The light-inlet end 180 is usually set to be relatively wide, so as to allow more light to enter the interior of the lens barrel and enhance the brightness of the field of view. The observation end 190 is relatively slender, so as to facilitate observation of the target from the lens barrel.

[0035] Preferably, a cover groove 112 is provided on the outer side of the first mounting groove 120; the light inlet end 180 of the first lens barrel 100 limits the installed lens through the front cover 113. The first mounting groove 120 is designed with a special cover groove 112 on the outside. The function of this structure is to install the front cover 113 so that it can fix and protect the internal lens assembly. The front cover 113 can also accurately position and limit the lens installed inside to ensure its stability and accuracy during operation. Not only improves the use efficiency of the equipment, but also extends the service life of the lens. Furthermore, the observation end 190 is also provided with a rear cover 114, and the rear cover 114 is used to limit the lens installed at the observation end 190.

[0036] See also Figure 1 The auxiliary mounting tube and the lens limiting tube 170 are arranged at intervals, and a lens mounting groove is formed between the auxiliary mounting tube and the lens limiting tube 170; the auxiliary mounting tube and the lens limiting tube 170 are tightly engaged and fixed to each other.

[0037] See also Figure 1Furthermore, a gap is left between the auxiliary mounting tube and the lens limiting tube 170 so as to set a travel lens mounting groove therebetween. In this way, the lens can move smoothly during the installation process to ensure smooth and accurate installation. At the same time, the auxiliary mounting tube and the lens limiting tube 170 need to be tightly engaged to ensure the stability between them and avoid displacement during the lens installation process. In addition, this tight engagement can also prevent accidental damage to the lens during the installation process. In order to achieve this goal, the auxiliary mounting tube and the lens limiting tube 170 are fixed after contacting each other to keep their relative positions unchanged. In this way, whether during the installation or use of the lens, the stability of the lens auxiliary mounting tube 160 and the lens limiting tube 170 can be ensured to improve the overall use effect.

[0038] See also Figure 1 , a fifth lens groove 181 and a sixth lens groove 182 are also provided inside the light inlet end 180. The internal structure of the light inlet end 180 is precise, and not only includes the basic lens structure, but also specially designed fifth lens groove 181 and sixth lens groove 182. These two lens grooves are specially provided to increase the complexity of the light path and improve the efficiency of light utilization. A lens is provided in the fifth lens groove 181, and the lens can reflect the light once before entering, thereby expanding the light sensing area. Similarly, a lens is also provided in the sixth lens groove 182, and its function is to further focus and adjust the light, ensuring that the light can be transmitted through the lens at the best angle, thereby improving the overall image quality and clarity. This design ensures that the light inlet end 180 not only ensures the efficient use of light, but also improves the performance and stability of the entire lens system.

[0039] See also Figure 2 and Figure 3 , the light-inlet end 180 is provided with a light-shielding tube 183; the light-shielding tube 183 is sleeved on the outer surface of the light-inlet end 180, and the light-shielding tube 183 is detachably mounted on the first lens barrel 100 by bolts 184. The light-shielding tube 183 is tightly sleeved on the outer surface of the light-inlet end 180, and can be detachably mounted on the first lens barrel 100 by bolts 184. Such a design allows the light-shielding tube 183 to be easily installed and removed, so as to effectively protect and shield the light-inlet end 180, while not affecting the function of the light-inlet end 180.

[0040] Preferably, a mounting plate 210 is provided on the fixed tube 200; and a mounting slot 220 is provided at one end of the fixed tube 200. A mounting plate 210 is designed on the fixed tube 200, and the mounting plate 210 can provide a plane for mounting or fixing other equipment or components. By setting the mounting plate 210, it can be adapted to a variety of photographic equipment and applied to shooting and observation in multiple fields.

[0041] See also Figure 3 The shading tube 183 is provided with shading sheets; the shading sheets are provided in four groups; each group of the shading sheets includes a vertical shading sheet 185 and an oblique shading sheet 186.

[0042] Each set of shading sheets is provided with shading sheets at different angles to provide the best shading effect in different situations. Each set of shading sheets is composed of two parts, one part is a vertical shading sheet 185, and the other part is an oblique shading sheet 186. This combined design enables the shading tube 183 to flexibly respond to various lighting conditions, effectively block unnecessary light, and ensure the user's observation and shooting experience.

[0043] Preferably, the vertical shading sheet 185 is arranged in parallel with the shading tube 183; the oblique shading sheet 186 and the vertical shading sheet 185 are arranged at a preset angle.

[0044] The vertical shading sheet 185 is arranged in parallel with the shading tube 183. This design can ensure that light enters in a vertical direction, thereby achieving the best shading effect. At the same time, the oblique shading sheet 186 is arranged at a preset angle with the vertical shading sheet 185, in order to ensure the shading effect while allowing a certain degree of light to pass through, thereby achieving the purpose of adjusting the light interference.

[0045] See also Figure 1 and Figure 2 The fixing cylinder 200 is provided with an adjusting cylinder 300, and the adjusting cylinder 300 is sleeved on one end of the fixing cylinder 200 where the mounting long hole 220 is provided. The mounting long hole 220 is processed at one end of the fixing cylinder 200, and the long hole has a long channel, allowing the adjusting cylinder 300 to rotate and move within a certain range on the fixing cylinder 200, thereby providing greater flexibility for installation or adjustment.
