Description

Technical Field

[0001] This utility model relates to a dual-image adjustment structure for binoculars. Background Technology

[0002] Currently available binoculars have the following structure: Figure 1 As shown, binoculars typically include a left eyepiece assembly, a right eyepiece assembly, a left prism, a right prism, a left objective lens assembly, and a right objective lens assembly. The left eyepiece assembly, left prism, and left objective lens assembly are spaced apart along the left optical axis in the left binocular tube; the right eyepiece assembly, right prism, and right objective lens assembly are spaced apart along the right optical axis in the right binocular tube. If the left and right optical axes are not parallel, the images from the left and right binocular tubes will not coincide, resulting in double images. Therefore, binoculars need to be adjusted at the factory to ensure that the left and right optical axes are parallel.

[0003] Currently, the dual-image adjustment structure for binoculars can be referenced from the utility model patent with patent number CN202320151352, entitled: "Binoculars with Vertical Adjustment and Overall Moving Prism Assembly". Traditional dual-image adjustment structures are complex, cumbersome to assemble, and the adjustment surfaces are not on the same side, making adjustment inconvenient and affecting efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a dual-image adjustment structure for binoculars, which solves the technical problems of existing binocular dual-image adjustment structures, such as complex structure, troublesome assembly, adjustment surfaces not being on the same side, inconvenient adjustment, and reduced adjustment efficiency.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A binocular dual-image adjustment structure includes a left eyepiece assembly, a right eyepiece assembly, a left prism, a right prism, a left objective lens assembly, and a right objective lens assembly. Its characteristic is that it further includes a dual-image adjustment structure, which comprises a fixed plate, a dual-image adjustment linkage, several eccentric pillars, and several screws, wherein:

[0007] The left eyepiece assembly, left prism, and left objective lens assembly are spaced apart along the left optical axis L1; the right eyepiece assembly, right prism, and right objective lens assembly are spaced apart along the right optical axis L2.

[0008] The left and right prisms are mounted in a frame to form an integral prism assembly;

[0009] The fixing plate includes a base plate, a left end plate and a right end plate that are bent and erected at the front end and spaced apart from each other, a left connecting plate at the top of the left end plate and a right connecting plate at the top of the right end plate;

[0010] The left and right objective lens assemblies are mounted on the rear end of the base plate, the right eyepiece assembly is mounted on the right end plate, and the left eyepiece assembly is mounted on the left end plate.

[0011] The dual-image adjustment linkage includes a left adjustment rod, a right adjustment rod, and an intermediate connecting seat for connecting the left and right adjustment rods; the left adjustment rod is connected to the left connecting plate by several screws, the right adjustment rod is connected to the right connecting plate by several screws, and the intermediate connecting seat is connected to the middle of the top of the frame by several second screws.

[0012] The aforementioned eccentric columns include a bottom rotating shaft and a top disc, the rotating shaft being offset from the center of the disc, and the top surface of the disc being provided with an adjustment groove;

[0013] Both the left and right adjusting rods are provided with a first oblong hole extending in the X direction and a second oblong hole extending in the Y direction; an eccentric column is installed in both the first and second oblong holes, the disc at the top of the eccentric column is nested in the first or second oblong hole, and the rotating shaft at the bottom of the eccentric column is nested in the round hole on the left or right connecting plate.

[0014] By utilizing the asymmetry principle of the eccentric column, the left and / or right adjustment rods are offset by turning the eccentric column, which in turn pulls the left and right end plates to twist and deform, thereby deflecting the left and right eyepiece assemblies and making the left optical axis L1 and the right optical axis L2 parallel, thus achieving the purpose of adjusting the double image.

[0015] Preferably, the right adjusting rod is connected to the right connecting plate by three screws arranged in a straight line, and the left adjusting rod is connected to the left connecting plate by three screws arranged in a straight line.

[0016] Preferably, the first oblong hole is located between two adjacent screws, and the second oblong hole is also located between two adjacent screws, with a screw positioned between the first oblong hole and the second oblong hole.

[0017] Preferably, the bottom of the frame is attached to the base plate.

[0018] Preferably, the prism assembly has an anti-shake function and has an anti-shake mechanism installed inside.

[0019] Preferably, the intermediate connecting seat is connected to the top center of the frame by three second screws arranged in a triangular pattern.

[0020] Compared with the prior art, this utility model has the following advantages:

[0021] Effect 1: The dual-image adjustment structure includes a fixed plate, dual-image adjustment linkage, several eccentric columns and several screws. The structure is relatively simple and easy to assemble.

[0022] Effect 2: Utilizing the asymmetry principle of the eccentric column, by twisting the eccentric column, the left and / or right adjustment rods are displaced, which pulls and deforms the left and right end plates, thereby deflecting the left and right eyepiece assemblies and making the left optical axis L1 and right optical axis L2 parallel, achieving the purpose of adjusting the double image. With all adjustment surfaces on the same side, adjustment is more convenient and efficiency is improved.

[0023] Other advantages of this invention will be described in more detail in the Embodiments section. Attached Figure Description
