Description

Technical Field

[0001] The utility model relates to the technical field of variable magnification image relay groups of aiming sights, in particular to a variable magnification image relay group of an aiming sight. Background Art

[0002] For the currently used civilian firearm sights, the image relay group adopted therein uses the traditional classic method of variable magnification realized by the movement of two positive lens groups described in optical design textbooks. The difference is only in the number of lenses used in each lens group. In terms of form, they are both two positive lens groups. The first lens group on the object side moves to compensate for image plane drift, and the second lens group on the image side moves to achieve variable magnification. Such a variable magnification image relay system can provide a sufficient exit pupil distance for the entire optical system of the firearm sight, avoid the damage to the human eye caused by the recoil force during shooting, and also achieve good optical performance.

[0003] Chinese Patent with the patent announcement number CN201449214U discloses a variable magnification image relay group of a civilian firearm sight, which includes a variable magnification cylinder with a variable magnification curve groove and three lens groups arranged to move along the curve groove on the variable magnification cylinder. The variable magnification curve groove has 3 grooves, namely the first curve groove and the third curve groove on both sides and the second curve groove in the middle. The first lens group of the three lens groups is arranged in the first curve groove, and this lens group is a positive refractive index lens group. The second lens group is arranged in the second curve groove, and this lens group is a negative refractive index lens group. The third lens group is arranged in the third curve groove, and this lens group is a positive refractive index lens group. In the utility model, the variable magnification image relay group of the firearm sight adopts a "positive-negative-positive" three-lens group mobile variable magnification image relay group. The advantage of adopting such an optical form is that the variable magnification efficiency is greatly improved, so that a high variable magnification ratio can be obtained with a relatively small movement amount of these three lens groups.

[0004] The existing variable magnification adjustment is mostly manual adjustment, which is not convenient for fast follow-up variable magnification adjustment. To overcome these disadvantages, the utility model provides a variable magnification image relay group of an aiming sight. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the defects existing in the prior art and propose a variable magnification image relay group of an aiming sight.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: a variable magnification image relay group of an aiming sight, which includes a connecting housing. Both ends of the connecting housing are fixedly connected with connecting cylinders. A first movable cylinder is sleeved outside the connecting cylinder on one side. One end of the first movable cylinder is fixedly connected with an eyepiece. A second movable cylinder is sleeved outside the connecting cylinder on the other side. One end of the second movable cylinder is fixedly connected with an objective lens. Adjusting components are arranged on both sides of the connecting housing for driving the first movable cylinder and the second movable cylinder to move.

[0007] Furthermore, a first moving lens group is arranged inside the first movable cylinder, and a second moving lens group is arranged inside the second movable cylinder.

[0008] Furthermore, the adjusting assembly includes a biaxial motor fixedly connected to the connecting housing. Both sides of the output end of the biaxial motor are fixedly connected with screw rods, and the thread directions of the screw rods are opposite.

[0009] Furthermore, a plurality of limiting rods are fixedly connected to both sides of the connecting housing. One end of each screw rod and one end of each limiting rod are fixedly connected with a limiting block.

[0010] Furthermore, connecting seats are fixedly connected to both the first movable cylinder and the second movable cylinder. The connecting seats are in threaded connection with the corresponding screw rods and are slidably connected to the corresponding limiting rods.

[0011] Furthermore, a mounting seat is fixedly connected to the upper end of the connecting housing. Laser rangefinders are fixedly connected to both sides of the mounting seat, and baffles are fixedly connected to the upper ends of the connecting seats.

[0012] Furthermore, a controller is fixedly connected to one side of the connecting housing. Operation buttons are arranged on the controller, and a storage battery and a processor are arranged inside the controller.

[0013] Advantages of the present utility model:

[0014] When the present utility model is in use, for the variable magnification image transfer group of the telescopic sight, the distance between the first movable cylinder and the second movable cylinder can be adjusted through the arranged adjusting assembly, so that the distance between the first moving lens group and the second moving lens group can be adjusted.
