[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figure 1-2The utility model provides a technical solution: an easily detachable eyepiece barrel structure of a sight, comprising: a lens body 1 and an eyepiece barrel 2, a connecting tube 7 is provided on one end of the eyepiece barrel 2 connected to the lens body 1, a connecting stud 3 is provided between the connecting tube 7 and the lens body 1, an inner lens barrel 8 is provided on one end of the lens body 1, and a dividing plate 10 is provided on the end of the inner lens barrel 8 facing the eyepiece barrel 2, a step barrel 6 is provided on the inner wall of one end of the eyepiece barrel 2 and between the inner lens barrel 8, a sealing ring 9 is provided between the step barrel 6 and the inner wall of the eyepiece barrel 2 at a position near the end, and a plurality of fastening screws 4 are provided between the step barrel 6 and the eyepiece barrel 2.

[0017] As a further improvement, the eyepiece tube 2 is connected to one end of the lens body 1 , and a plurality of grooves are evenly provided on the outer edge of the connecting tube 7 , and the outer edge of the connecting tube 7 protrudes from the eyepiece tube 2 .

[0018] As a further improvement, a portion of the connecting stud 3 is threadedly connected to the connecting tube 7, one end of the connecting stud 3 is in contact with the inner lens barrel 8, and the dividing plate 10 is threadedly connected to the inner lens barrel 8.

[0019] As a further improvement, a sealing ring 5 is provided between the outer edge of the eyepiece barrel 2 near the end and the connecting member 7, and the cross-section of the sealing ring 5 is a circular structure. The step barrel 6 is threadedly connected to the eyepiece barrel 2, and the step barrel 6 has a chamfer on the outer edge of the end facing the eyepiece barrel 2.

[0020] As a further improvement, grooves for cooperating with a sealing ring 9 are provided on both the step tube 6 and the eyepiece tube 2. The cross section of the sealing ring 9 is an elliptical structure, and the fastening screw 4 is threadedly connected to the eyepiece tube 2; one end is against the step tube 6.

[0021] During use: The utility model adds a step tube at the eyepiece tube, which increases the end face contact when it contacts and locks with the end face of the lens body, which helps to prevent loosening. Since there is always a gap in the threaded connection, the sight will be subjected to vibration when shooting with a hunting rifle. In order to eliminate the looseness caused by frequent vibration, a sealing ring is added to have a shock-absorbing effect. Frequent vibration use will cause the eyepiece tube to become loose along the screw thread. In order to avoid this hidden danger, three fastening screws 4 are added to the front end circle of the eyepiece tube 2 to lock it. This can prevent the screw production line between the eyepiece tube 2 and the lens body 1 from rotating and loosening.

[0022] The lens body-1, eyepiece barrel-2, connecting stud-3, fastening screw-4, sealing ring 2-5, step tube-6, connecting barrel-7, inner barrel-8, sealing ring 1-9, and reticle plate-10 of the present invention are all universal standard parts or parts known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. The problem solved by the present invention is that AB glue has strong adhesion and needs to be heated when disassembling the eyepiece barrel, which easily causes secondary contamination of the glass in the cavity and is more troublesome and laborious. The present invention combines the above components with each other and cooperates with the sealing ring 1-9 and the step tube 6 of the present invention to conveniently connect and disassemble the eyepiece barrel 2 to the lens body 1. There is no need to use AB glue for connection at the threaded connection. A step tube 6 is added to the eyepiece barrel 2. When it contacts and locks with the end face of the lens body 1, the end face contact is increased, which helps to prevent loosening. The sealing ring 1-9 can effectively reduce vibration during shooting and achieve a shock absorption effect.
