[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0025] As Figures 1-6 shown, it relates to an eight-fold variable magnification optical sight structure, including a lens barrel 1. One end of the lens barrel 1 is fixedly connected with an eyepiece 2. The outer wall of the eyepiece 2 is fixedly connected with a rubber eye shield 3. The outer wall of the lens barrel 1 is fixedly sleeved with a positioning ring 4. The outer wall of the lens barrel 1 is provided with an objective lens 5.

[0026] A docking ring 6 is fixedly sleeved on the outer wall of the objective lens 5. A rubber gasket can be added to the contact surface between the positioning ring 4 and the docking ring 6 to enhance waterproofness and sealing performance. Two T-shaped positioning posts 7 are fixedly connected to the outer wall of the positioning ring 4. Two arc-shaped grooves 18 are formed in the outer wall of the docking ring 6, and the inner walls of the two arc-shaped grooves 18 are respectively slidably connected to the outer walls of the two T-shaped positioning posts 7.

[0027] A clamping mechanism is provided on the outer wall of the docking ring 6. The clamping mechanism includes two cylinders 8. Two sliding grooves are formed in the outer wall of the docking ring 6, and the inner walls of the two sliding grooves are respectively slidably connected with arc-shaped sliding plates 10. The outer walls of the two arc-shaped sliding plates 10 are respectively fixedly connected to the outer walls of the two cylinders 8. Two circular holes are formed in the outer wall of the docking ring 6, and the inner walls of the two circular holes are respectively slidably connected to the outer walls of the two cylinders 8. When the outer walls of the two arc-shaped sliding plates 10 move leftward, the two cylinders 8 can be driven to slide out of the two jacks 11 respectively.

[0028] One end of each of the two cylinders 8 is fixedly connected with a spring 9. One end of the spring 9 is fixedly connected to the inner wall of the circular hole. The spring 9 supports the cylinder 8 and ensures that the cylinder 8 is subsequently located in the jack 11 through its elastic force. Two jacks 11 are formed in the outer wall of the positioning ring 4.

[0029] A shielding mechanism is provided on the outer wall of the objective lens 5. The shielding mechanism includes a round cover 13. Two silicone ropes 12 are fixedly connected to the outer wall of the docking ring 6. The two silicone ropes 12 have elastic properties. One end of each of the two silicone ropes 12 is fixedly connected to the outer wall of the round cover 13. A light extinction mesh sheet 14 is fixedly inlaid on the outer wall of the round cover 13. The light extinction mesh sheet 14 has certain holes, which will not block the field of view and at the same time reduce the reflection of the lens.

[0030] A T-shaped hole is formed in the outer wall of the round cover 13. A T-shaped damping rod 15 is rotatably connected to the inner wall of the T-shaped hole. The T-shaped damping rod 15 and the T-shaped hole are in interference fit and have friction, which is used as damping through the friction. A circular light shielding sheet 16 is fixedly connected to the outer wall of the T-shaped damping rod 15. A rotation assisting rod 17 is fixedly connected to the outer wall of the circular light shielding sheet 16. The rotation assisting rod 17 drives the circular light shielding sheet 16 to rotate. The outer wall of the circular light shielding sheet 16 is slidably connected to the outer wall of the round cover 13.

[0031] Working principle: When replacing the objective lens 5, hold the docking ring 6 and the lens barrel 1 with both hands respectively. One hand presses the outer walls of the two arc-shaped sliding pieces 10 and moves them to the left to drive the two cylinders 8 to move to the left along the two circular holes, so that the two cylinders 8 slide out of the two jacks 11 respectively. The other hand rotates the lens barrel 1 to drive the positioning ring 4 to rotate, so that the positioning ring 4 drives the two T-shaped positioning columns 7 to rotate. After the two T-shaped positioning columns 7 rotate to the first ends of the two arc-shaped grooves 18, pulling them outwards can separate the objective lens 5 from the lens barrel 1. The overall snap-fit method forms a whole, which is not easy to fall off and increases the connection strength between the lens barrel 1 and the objective lens 5; when installing the objective lens 5, after aligning the positioning ring 4 on the lens barrel 1 with the docking ring 6 on the objective lens 5, slide the two T-shaped positioning columns 7 into the two arc-shaped grooves 18 respectively, and slide them in along the circular opening positions at the first ends of the arc-shaped grooves 18. At this time, the two cylinders 8 contact the outer wall of the positioning ring 4 and move to the left under the extrusion force. Then rotate the positioning ring 4, and the two T-shaped positioning columns 7 rotate and slide into the second ends of the two arc-shaped grooves 18. At this time, the two T-shaped positioning columns 7 are clamped in the two arc-shaped grooves 18, and the objective lens 5 and the lens barrel 1 cannot move left and right. And after rotating a certain angle, the two cylinders 8 slide into the two jacks 11 respectively under the elastic force of the two springs 9, so that the objective lens 5 and the lens barrel 1 cannot rotate, completing the fixation; pull the round cover 13 to the left to stretch the two silica gel ropes 12 to the left, and the round cover 13 can be separated from one end of the objective lens 5. At the same time, rotating the circular light-shielding sheet 16 can protect the lens in the objective lens 5, and the extinction mesh sheet 14 reduces the reflection of the lens in the objective lens 5.
