[0002] The lens barrel is an important component of optical equipment. It is usually used to fix and protect optical lenses. It also plays the role of shading and reducing stray light. The design and manufacturing quality of the lens barrel directly affect the performance and stability of the optical equipment. The structure of the lens barrel usually includes the barrel body, end caps, fixing rings and other parts. The barrel body is the main load-bearing part, and the end caps and fixing rings are used to fix and seal the lenses. The working principle of the lens barrel is to fix the lenses in the correct position through precise mechanical structure to ensure that light can pass through the lenses accurately, thereby realizing the function of the optical equipment.

[0003] In practical applications, the same movement and housing structure may need to be replaced with lens barrels of different focal lengths or different optical parameters for actual observation. Most existing structural interfaces are cumbersome to operate when replacing lenses, which easily reduces the efficiency of lens replacement. To this end, we provide a locking structure that facilitates the replacement of lens barrels to solve the above problems. Utility Model Content

[0024] It includes a mirror body 1, a connecting ring 2 and a connecting block 5. Three groups of locking grooves 3 are provided on the outside of the connecting ring 2, and the locking grooves 3 are arc-shaped and opened on the outside of the connecting ring 2. A corrugated gasket 4 is provided at one end of the mirror body 1. The corrugated gasket 4 is a gasket with wavy concave and convex lines. The corrugated gasket 4 is located inside the connecting ring 2. A locking block 8 is provided inside the connecting block 5, and the locking block 8 can be inserted into the inside of the locking groove 3.

[0025] The connecting ring 2 is fixedly arranged at one end of the mirror body 1, and the positioning grooves 3 are symmetrically arranged in three groups in the shape of an arc on the outside of the connecting ring 2. The positioning grooves 3 are used to provide assembly positioning space for the positioning blocks 8 arranged on the inner side of the installation groove 10. The corrugated gasket 4 is a gasket with wavy concave and convex lines. The corrugated gasket 4 can be made of carbon spring steel or stainless steel. The corrugated gasket 4 can play the role of a wave transition boundary under pressure and can ensure sealing. The structure of the corrugated gasket 4 is a circular thin sheet with a regular wavy shape. Through its wavy design, the corrugated gasket 4 can provide elasticity and impact resistance when subjected to pressure, thereby preventing loosening and relieving impact. When a different lens barrel needs to be replaced, the connecting ring 2 is inserted into the outer side of the retaining ring 6, and the blocking block 8 inside the mounting groove 10 can be inserted into the inside of the blocking groove 3. The pressure generated by pressing the lens body 1 causes the corrugated gasket 4 to deform, and then the lens body 1 is rotated to cause the blocking block 8 to rotate to the arc groove inside the blocking groove 3. The corrugated gasket 4 rebounds to clamp the connecting block 5 and the connecting ring 2. The structure is relatively simple to operate, effectively improving the efficiency of lens replacement and saving replacement time.

Multiple groups of mounting holes 9 are located on one side of the mounting groove 10.

[0028] The mirror body 1 is the main part of the optical device. It contains key components of the optical system, such as objective lens, eyepiece, prism, etc. These components work together to enable light to pass correctly and form a clear image. The design and quality of the mirror body 1 directly affect the performance of the optical device, including resolution, contrast, color reproduction, etc. The mounting groove 10 is opened inside the connecting block 5. The mounting groove 10 provides installation space for the retaining ring 6 and the pressure plate 7. The retaining ring 6 is a mechanical part used to limit or prevent the movement of the pressure plate 7, ensure that the pressure plate 7 is in the correct position, and prevent the pressure plate 7 from exceeding its design range during movement, thereby avoiding damage or accidents, and ensuring the stability of the contact between the pressure plate 7 and the corrugated gasket 4. During the docking process between the connecting ring 2 and the connecting block 5, the pressure plate 7 inside the retaining ring 6 can contact the corrugated gasket 4. By pressing the mirror body 1, the pressure plate 7 can squeeze the corrugated gasket 4 to deform. The mounting hole 9 provides installation space for external positioning components, such as bolts and other components, which facilitates the positioning and installation of the connecting block 5.
