Two eyepieces are mounted on the front of the adjustment component. The adjustment component includes two hollow adjustment shafts and a connecting plate. The two hollow adjustment shafts are located on the left and right sides of the front of the binoculars base, respectively. In this utility model, the angles of the left and right prisms need to be adjusted simultaneously. Rotating the drive shaft clockwise or counterclockwise drives the corresponding two intermediate gears to rotate. The intermediate gears drive the corresponding large gears to rotate, ultimately rotating the hollow adjustment shafts and changing the angles of the two prisms. If only the right prism needs adjustment, first, reverse the adjustment screw to move the moving block forward. At this time, the moving plate and the components above it move forward together until the left intermediate gear disengages from the left large gear.

Description

Technical Field

[0001] This utility model relates to the field of binoculars technology, specifically a wide field-of-view binoculars with an adjustable prism module. Background Technology

[0002] Binoculars have the advantages of clear and bright imaging, large field of view, portability and low price, making them very suitable for astronomy enthusiasts to use for sky surveys and observation of planar celestial objects such as nebulae, star clusters and comets.

[0003] A search revealed patent number CN217332993U, entitled "A Binocular with an Adjustable Prism Module." The binoculars comprise two sets of telescope bodies, with a moving shaft at the center of each body. Above the moving shaft are two sets of eyepieces, each with an eyepiece at its front end. A prism sheet is located at the upper end of each telescope body, and an objective lens at the lower end. An adjustment shaft is located above the moving shaft, with a gear fixedly mounted at its rear end. An upper rack meshes with the upper part of the gear, and a lower rack meshes with the lower end of the gear. Two pairs of adjustment rods are located inside the telescope body, fixedly mounted at the lower ends of the upper and lower racks respectively. An adjustment handwheel is located above the eyepiece sets, with a handwheel ring fixedly mounted inside. The inner side of the handwheel ring has a groove. This invention provides a convenient and efficient adjustment function. However, research and analysis revealed that while it has an adjustment function, it also has the following drawbacks to some extent.

[0004] For example, the adjustment method is singular, allowing adjustment only to one side of the prism at a time. When both prisms need to be adjusted simultaneously, they must be adjusted separately, which can easily lead to errors between them and is detrimental to subsequent observation. To solve these technical problems, we have designed a wide-field binoculars with an adjustable prism module. Utility Model Content

[0005] The purpose of this invention is to provide a wide field-of-view binocular with an adjustable prism module, which has the advantages of multiple adjustment methods. It solves the problems of single adjustment method, only one side of the prism can be adjusted at a time, and when both prisms need to be adjusted at the same time, they need to be adjusted separately, which can easily lead to errors between the two and is not conducive to subsequent observation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wide-field binoculars with an adjustable prism module, comprising a binoculars base, wherein an adjustment component is installed on the bottom and front side of the binoculars base, and two eyepieces are installed on the front side of the adjustment component. The adjustment component includes two hollow adjustment shafts and a connecting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention offers multiple adjustment methods through the use of adjusting components. The angles of the left and right prisms need to be adjusted simultaneously. Rotating the drive shaft clockwise or counterclockwise drives the corresponding two intermediate gears to rotate, which in turn drive the corresponding large gear, ultimately rotating the hollow adjusting shaft and changing the angles of both prisms. If only the right prism needs adjustment, first, reverse the adjusting screw to move the moving block forward. The moving plate and its components above it move forward together until the left intermediate gear disengages from the left large gear. Then, rotating the drive shaft clockwise or counterclockwise completes the adjustment of the right prism. If only the left prism needs adjustment, first, rotate the adjusting screw clockwise to move the moving block backward. The moving plate and its components above it move backward together until the right intermediate gear disengages from the right large gear. Then, rotating the drive shaft clockwise or counterclockwise completes the adjustment of the left prism. Attached Figure Description

[0015] Please see Figures 1-4A wide-field binoculars with an adjustable prism module includes a binoculars base 1. An adjustment component 3 is installed on the bottom and front of the binoculars base 1. Two eyepieces 2 are installed on the front of the adjustment component 3. The adjustment component 3 includes two hollow adjustment shafts 31 and a connecting plate 311. The two hollow adjustment shafts 31 are located on the left and right sides of the front of the binoculars base 1, respectively. The rear side of the hollow adjustment shafts 31 extends into the interior of the binoculars base 1. A prism 32 is installed on the hollow adjustment shafts 31. A large gear 310 is connected to the front of the hollow adjustment shafts 31. A support ring 33 is connected to the center of the front side of the large gear 310. The rear side of the eyepieces 2 extends to the inner wall of the support ring 33 and the large gear 310 and is movably connected to the inner wall of the support ring 33 and the large gear 310 through bearings. The top of the connecting plate 311 is connected to the binoculars base 1.

[0016] A support plate 37 is connected to the bottom of the front side of the connecting plate 311. A moving groove 35 is opened through the top of the support plate 37. An adjusting screw 36 is movably connected to the rear side of the inner wall of the moving groove 35 through a bearing. The front side of the adjusting screw 36 extends through to the front side of the support plate 37.

[0017] A moving block 38 is threaded onto the outside of the adjusting screw 36 and on the inner wall of the moving groove 35. A moving plate 34 is connected to the top of the moving block 38. Vertical plates 314 are connected to the four corners of the top of the moving plate 34. A rotating shaft 316 is provided between the front and rear vertical plates 314. The bottom of the moving plate 34 is in sliding contact with the top of the bearing plate 37. A rotating hole is provided on the vertical plate 314 to cooperate with the rotating shaft 316. The inner wall of the rotating hole is movably connected to the rotating shaft 316 through a bearing.

[0018] An intermediate gear 315 is fixedly sleeved at the center of the outer side of the rotating shaft 316. A support plate 39 is connected between the two vertical plates 314 on the left and right sides. A drive shaft 312 is installed through the two support plates 39 on the front and rear sides. A drive gear 313 is fixedly sleeved at the center of the outer side of the drive shaft 312. The drive gear 313 meshes with the two intermediate gears 315. The intermediate gears 315 mesh with the large gear 310. The longitudinal thickness of the intermediate gears 315 is less than the longitudinal thickness of the large gear 310. The two intermediate gears 315 are on the same straight line.

[0019] The front and rear support plates 39 are provided with rotating holes that cooperate with the drive shaft 312. The inner wall of the rotating hole is movably connected to the drive shaft 312 through a bearing.

[0020] The two large gears 310 are staggered and have the same number of teeth and outer diameter. The outer diameter of the large gear 310 is larger than that of the intermediate gear 315, the outer diameter of the intermediate gear 315 is larger than that of the driving gear 313, the number of teeth of the large gear 310 is much greater than that of the intermediate gear 315, and the number of teeth of the intermediate gear 315 is much greater than that of the driving gear 313.

[0021] In use, if the angles of the left and right prisms 32 need to be adjusted simultaneously, rotate the drive shaft 312 clockwise or counterclockwise. The drive gear 313 will drive the corresponding two intermediate gears 315 to rotate, which in turn will drive the corresponding large gear 310 to rotate, ultimately rotating the hollow adjustment shaft 31. This simultaneously changes the angles of the two prisms 32. Once the desired angle is achieved, stop rotating the drive shaft 312. If only the right prism 32 needs adjustment, first, reverse the adjustment screw 36 to move the moving block 38 forward. At this time, the moving plate 34 and its upper components move forward together until the left intermediate gear 315 disengages from the left large gear 310. Then, rotate the drive shaft 312 clockwise or counterclockwise to adjust the right prism 32. If only the left prism 32 needs adjustment, first, rotate the adjustment screw 36 clockwise to move the moving block 38 backward. At this time, the moving plate 34 and its upper components move backward together until the right intermediate gear 315 disengages from the left large gear 310. When the large gear 310 on the right engages, rotating the drive shaft 312 clockwise or counterclockwise will adjust the left prism 32. It should be noted that when adjusting the left or right prism 32 separately, since the two intermediate gears 315 still rotate together, it does not affect the subsequent meshing between the intermediate gear 315 and the large gear 310 on the unadjusted side. Furthermore, as the number of teeth of the drive gear 313, intermediate gear 315 and large gear 310 gradually increases, the rapidly rotating drive shaft 312 will only drive the large gear 310 and the hollow adjustment shaft 31 to rotate slowly, resulting in high adjustment accuracy.

[0022] In summary, this wide-field binoculars with an adjustable prism module solves the problem of limited adjustment methods by using adjustment component 3. Previously, only one side of the prism could be adjusted at a time, and when both prisms needed to be adjusted simultaneously, they had to be adjusted separately, which could easily lead to errors and hinder subsequent observation.
