Description

Technical Field

[0001] The utility model relates to the technical field of sights, in particular to a side focusing structure of an optical sight. Background Art

[0002] The side focus of a scope refers to adjusting the windage compensation (or lead) by turning the side knob. The side focus function of a scope allows the user to adjust the height and left and right offset of the trajectory by turning the side knob to adapt to different shooting conditions and target distances. The side focus of a scope is usually on the left. The side focus knob of a scope is usually located on the left side of the precision adjustment, which makes it easier to adjust the parallax.

[0003] In the prior art, the focusing hand wheel is used to focus by rotating. However, since the focusing hand wheel is located on the left side of the lens barrel, it is easy to be accidentally touched when carrying or placing, resulting in the need for multiple focusing adjustments. Therefore, we propose an optical sight side focusing structure to solve the above problem. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Depend on Figure 1-Figure 4 As shown, it relates to a side focusing structure of an optical sight, including a connecting seat 1, two tube clamps 2 are fixedly connected to the top of the connecting seat 1, the same lens barrel 3 is placed inside the two tube clamps 2, the two tube clamps 2 fix the lens barrel 3 on the connecting seat 1, the outer walls of the tube clamps 2 and the connecting seat 1 are both installed with countersunk bolts, the outer wall of the lens barrel 3 is rotatably connected to a height adjustment hand wheel 4, the outer wall of the lens barrel 3 is rotatably connected to a direction adjustment hand wheel 5, one end of the lens barrel 3 is fixedly connected to an eyepiece 6, the outer wall of the eyepiece 6 is fixedly connected to a dustproof cover 7, the dustproof cover 7 protects the eyepiece 6, and the other end of the lens barrel 3 is fixedly connected to an objective lens 8.

[0023] The outer wall of the lens barrel 3 is rotatably connected with a focusing cylinder 9, and the outer wall of the focusing cylinder 9 is fixedly sleeved with a gasket 10 and a rubber ring 11, which are fixedly connected. The gasket 10 contacts the outer wall of the lens barrel 3, and there is a certain damping between the two.

[0024] A T-slot is provided on the outer wall of the focusing cylinder 9, and a T-column 12 is rotatably connected to the inner wall of the T-slot. The outer wall of the T-column 12 is coated with lubricating oil to reduce friction. A disc 13 is fixedly connected to one end of the T-column 12. The circular sleeve 14 and the circular sleeve 13 rotate in the T-slot through the T-column 12. The outer wall of the circular sleeve 13 is slidably connected to the outer wall of the focusing cylinder 9, and the outer wall of the focusing cylinder 9 is sleeved with a circular sleeve 14.

[0025] A focusing mechanism is provided on the outer wall of the circular sleeve 14, and the focusing mechanism includes two springs 15. One ends of the two springs 15 are fixedly connected to the outer wall of the disc 13, and the other ends of the two springs 15 are fixedly connected to the inner wall of the circular sleeve 14. The two springs 15 ensure that the circular sleeve 14 is away from the gasket 10 and the rubber ring 11. A focusing hand wheel 16 is fixedly provided on the outer wall of the circular sleeve 14. A plurality of triangular tooth blocks 17 are fixedly connected to the outer wall of the circular sleeve 14. The plurality of triangular tooth blocks 17 are arranged in a ring shape. After the plurality of triangular tooth blocks 17 are squeezed with the rubber ring 11, the damping is overcome and the focusing cylinder 9 is driven to rotate.

[0026] Working principle: When in use, the connecting seat 1 is installed on the gun connecting seat. When focusing, the focusing hand wheel 16 is pressed inward to drive the circular sleeve 14 to move inward. The circular sleeve 14 moves inward to compress the two springs 15. The circular sleeve 14 moves to move the multiple triangular tooth blocks 17 to contact the outer wall of the rubber ring 11, completing the extrusion and fixation between the focusing cylinder 9, so that after the focusing hand wheel 16 rotates, the rubber ring 11 and the gasket 10 are rotated, and the rotation of the gasket 10 drives the circular sleeve 14 to rotate, so as to achieve The focusing process is now present, and when focusing is not needed, the elastic force of the two springs 15 drives the round sleeve 14 and the focusing hand wheel 16 away from the rubber ring 11 and the gasket 10. When the focusing hand wheel 16 is accidentally touched and rotated, the round sleeve 14, the two springs 15 and the disc 13 rotate. Since the disc 13 is in a rotational connection relationship with the focusing cylinder 9 through the T-column 12, the focusing cylinder 9 cannot rotate. In addition, the focusing hand wheel 16 is designed to be enlarged to protect the focusing cylinder 9 from external influences, and at the same time, it is convenient for the round sleeve to bear force and focus.
