[0032] 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.

[0033] Reference Figure 3 , Figure 4 and Figure 5 This utility model provides an embodiment of a fiber optic field lens mount lens positioning and mounting frame, including a mounting base 1. The mounting base 1 serves as the basic support structure of the entire frame, providing a support for the installation and fixation of other components. A mounting groove 3 is provided on the front side of the inner wall of the mounting base 1 to accommodate an elastic compensation ring 4, providing an installation position for the elastic compensation ring 4. The inner wall of the mounting groove 3 is provided with the elastic compensation ring 4, which is used to clamp the lens 5 and simultaneously uses its own elasticity to buffer the influence of external temperature changes and vibrations on the position of the lens 5. The inner wall of the elastic compensation ring 4 is slidably connected to the lens 5, which is the core optical component of the fiber optic field lens mount. Initial positioning is achieved through the slidable connection with the elastic compensation ring 4. Adjusting screws 6 are threadedly connected to all four sides of the outer wall of the mounting base 1. The adjacent ends of multiple adjusting screws 6 are connected to the elastic compensation ring 4. The compensation ring 4 is fitted to adjust the position of the elastic compensation ring 4, thereby achieving fine adjustment of the position of the lens 5. A sealing ring 7 is fixedly connected to the front side of the outer wall of the elastic compensation ring 4 to prevent dust and impurities from entering the interior of the mounting base 1 and affecting the optical performance of the lens 5. A fixing ring 8 is slidably connected to the inner wall of the sealing ring 7. The fixing ring 8 is used to further fix the clamping ring 9 and the lens 5 to ensure the stability of the entire structure. A clamping ring 9 is slidably connected to the rear side of the inner wall of the fixing ring 8. By squeezing the lens 5, the lens 5 is kept stable in the mounting base 1. The rear end of the clamping ring 9 is fitted with the lens 5 to achieve clamping and fixing of the lens 5 and prevent the lens 5 from shifting during use. An adjustment mechanism 2 is provided on the outer wall of the clamping ring 9. The adjustment mechanism 2 is used to adjust the extension length of the clamping ring 9 to squeeze lenses 5 of different thicknesses.

[0034] Specifically, the mounting base 1 serves as the basic support structure. Its inner wall has a mounting groove 3 on the front side to accommodate the elastic compensation ring 4. The inner wall of the elastic compensation ring 4 is slidably connected to the lens 5, clamping and fixing the lens 5. It utilizes its own elasticity to buffer the effects of external temperature changes and vibrations on the position of the lens 5. Adjusting screws 6 are threaded around the outer wall of the mounting base 1, with one end of each screw fitting against the elastic compensation ring 4. Rotating the adjusting screws 6 clamps the elastic compensation ring 4 and adjusts the position of the lens 5, achieving fine-tuning. A sealing ring 7 is fixed to the front side of the outer wall of the elastic compensation ring 4, and its inner wall is slidably connected to a fixing ring 8. The retaining ring 8 serves as a seal to prevent impurities from entering and affecting optical performance. The rear side of the inner wall of the retaining ring 8 is slidably connected to the clamping ring 9. The rear end of the clamping ring 9 is attached to the lens 5 for further fixing the lens 5. The adjustment mechanism 2 on the outer wall of the clamping ring 9 adjusts the extension length of the clamping ring 9 so that the clamping ring 9 can adjust the distance between the clamping ring 9 and the lens 5 according to the thickness of the lens 5, thereby achieving compression and fixing of lenses 5 of different thicknesses, ensuring the stability and adaptability of the lens 5 installation. The coordinated operation of all components effectively solves the problem of fixing the lens 5 in different environments and adapting to different lens 5 thicknesses.

[0035] Reference Figure 3 and Figure 6 The adjusting mechanism 2 includes multiple limiting blocks 201. The outer walls of the multiple limiting blocks 201 are fixedly connected to the front periphery of the outer wall of the clamping ring 9, so that the limiting blocks 201 and the clamping ring 9 form a whole and move together with the clamping ring 9. The inner wall of the fixed ring 8 is provided with multiple limiting grooves 202. The multiple limiting blocks 201 are slidably connected to the corresponding limiting grooves 202. The limiting grooves 202 cooperate with the limiting blocks 201 to provide guidance for the movement of the clamping ring 9. The inner wall of the fixed ring 8 The four sides are provided with reserved slots 203 to provide space for the installation and rotation of bolts 204. Bolts 204 are rotatably connected to the inner walls of multiple reserved slots 203. The bolts 204 adjust the position of the clamping ring 9 by rotating. Multiple sleeves 205 are fixedly connected to the front end of the outer wall of the clamping ring 9. Multiple bolts 204 are threadedly connected to the corresponding sleeves 205. The sleeves 205 cooperate with the bolts 204 to convert the rotation of the bolts 204 into the linear movement of the clamping ring 9.

[0036] Specifically, multiple limiting blocks 201 are fixed around the front side of the outer wall of the clamping ring 9 and are slidably connected to the limiting grooves 202 opened around the inner wall of the fixing ring 8, limiting the movement direction of the clamping ring 9 so that it can only move back and forth, ensuring that the adjustment process is stable and accurate in direction. The reserved grooves 203 around the inner wall of the fixing ring 8 provide rotation space for the bolt 204, in which the bolt 204 rotates. The sleeves 205 fixed around the front end of the outer wall of the clamping ring 9 are threadedly connected to the bolt 204. When the bolt 204 is rotated, due to the thread transmission principle, the rotation of the bolt 204 is converted into axial force. The sleeves 205 cannot rotate on their own because they are fixed to the clamping ring 9, and can only drive the clamping ring 9 to move back and forth along the direction limited by the limiting blocks 201 and the limiting grooves 202, thereby accurately adjusting the distance between the clamping ring 9 and the lens 5, realizing reliable compression and fixing of lenses 5 of different thicknesses, and ensuring the adaptability of the fiber optic field lens mount lens 5 positioning and installation frame to various types of lenses 5.

[0037] Reference Figure 1 , Figure 2 and Figure 4 The top of the mounting base 1 has grooves 10 around its four sides. The inner walls of the grooves 10 are threaded with protective sleeves 11 to protect the adjusting screws 6. The outer walls of the protective sleeves 11 are fixedly connected with multiple anti-slip strips 12 to facilitate tightening the protective sleeves 11. The front and rear sides of the outer wall of the mounting base 1 are fixedly connected with multiple anti-collision rings 13 and multiple anti-collision strips 14. The multiple anti-collision rings 13 are fixedly connected to the multiple anti-collision strips 14 to buffer side impacts and protect the internal structure. The rear left and right sides of the mounting base 1 are fixedly connected with T-shaped sliders 15. The surfaces of the two T-shaped sliders 15 are treated with anti-slip material to facilitate stable connection of the mounting base 1 with other components and prevent excessive sliding during installation.

[0038] Specifically, the grooves 10 around the top of the mounting base 1 are threadedly connected to the protective sleeve 11. The anti-slip strips 12 on the protective sleeve 11 facilitate the tightening of the protective sleeve 11. The protective sleeve 11 can protect the adjusting screw 6. The anti-collision ring 13 and anti-collision strip 14 on the outer wall of the mounting base 1 are connected to buffer side impacts and protect the internal structure. The T-shaped slider 15 at the rear end is treated with anti-slip to facilitate the stable connection of the mounting base 1 with other components and prevent excessive sliding during installation.

[0039] Reference Figure 1 , Figure 5 and Figure 7The inner walls of multiple pre-reserved slots 203 are slidably connected with plugs 16 to prevent bolts 204 from being damaged by external factors. The outer walls of multiple plugs 16 are fixedly connected with rings 17 to facilitate the removal and placement of plugs 16. The outer wall of the mounting base 1 is provided with a threaded groove 18. The outer wall of the threaded groove 18 is threadedly connected with a protective cover 19 to press the components inside the mounting base 1. The rear side of the outer wall of the protective cover 19 fits against the fixing ring 8. The cross-sections of the elastic compensation ring 4 and the sealing ring 7 are both oblique trapezoidal to facilitate the entry of components. The cross-sectional area of ​​the left end of the elastic compensation ring 4 and the sealing ring 7 is smaller than that of the right end, and they will gradually tighten during the insertion of components.

[0040] Specifically, the plug 16 in the reserved groove 203 prevents the bolt 204 from being damaged by the outside. The ring 17 facilitates the removal and placement of the plug 16. The protective cover 19 is used to tighten each component to prevent loosening between components. The cross-section of the elastic compensation ring 4 and the sealing ring 7 is a slanted trapezoid, smaller on the left and larger on the right. When the component is inserted, it gradually tightens, which is conducive to the entry of the component and ensures the sealing and stability of the installation.

[0041] Working Principle: During installation, the elastic compensation ring 4 is first inserted into the mounting groove 3 from the left side of the mounting base 1. This key component, the elastic compensation ring 4, due to its inherent elasticity, plays multiple roles when the lens 5 is subsequently placed in its central position. Firstly, it tightly clamps and fixes the lens 5, providing initial stable support. Secondly, when encountering external temperature changes, its elasticity can buffer the frame deformation stress caused by thermal expansion and contraction, preventing this stress from being directly transmitted to the lens 5, thereby reducing the positional displacement of the lens 5 due to temperature changes. Simultaneously, in a vibration environment, the elasticity of the elastic compensation ring 4 can also absorb vibration energy, reducing the impact of vibration on the position of the lens 5. The mounting base 1 has threads connecting all four sides. The adjusting screw 6 further enhances the control over the position of the lens 5. After the elastic compensation ring 4 is installed in place, the adjusting screw 6 is rotated so that its adjacent end fits against the elastic compensation ring 4 and is clamped. By precisely rotating the adjusting screw 6, pressure of different directions and degrees can be applied to the elastic compensation ring 4, thereby fine-tuning the position of the lens 5 and achieving high-precision position adjustment. Subsequently, the sealing ring 7 is placed on the left side of the inner wall of the mounting base 1, and the fixing ring 8 is slid until it fits tightly against the sealing ring 7. At this time, the clamping ring 9 on the rear side of the inner wall of the fixing ring 8 can fit against the lens 5 and further fix the lens 5. The sealing ring 7 not only plays a sealing role to prevent dust and other impurities from entering and affecting the optical performance, but also buffers external vibrations to a certain extent.

[0042] Furthermore, when it is necessary to fix lenses 5 of different thicknesses, the operator rotates multiple bolts 204. Due to the characteristics of threaded transmission, when the bolts 204 rotate, a force is generated along the thread axis. At this time, the sleeve 205, being fixed together with the clamping ring 9, cannot rotate on its own. It can only drive the clamping ring 9 to move along the front-back direction defined by the limiting block 201 and the limiting groove 202 under the force of the bolts 204. The operator can accurately adjust the position of the clamping ring 9 according to the actual thickness of the lens 5, so that it fits tightly with the lens 5, thereby providing appropriate and stable pressure for lenses 5 of different thicknesses and achieving reliable fixing of various types of lenses 5.
