Description

Technical Field

[0001] This utility model relates to the field of telescope technology, and in particular to a mechanical transmission adjustment component for a telescope. Background Technology

[0002] The mechanical transmission adjustment mechanism of binoculars is the core component for achieving usability. It is mainly used to adjust the distance between the tubes, focal length, and parallax, ensuring clear images and user comfort when observing alone. It is a key functional module of binoculars.

[0003] The existing adjustment components mainly include a hinged central axis connecting the two lens barrels, a lens barrel rotation structure for interpupillary distance adjustment, a central synchronous focusing knob, and an eyepiece diopter adjustment ring. The distance is changed by rotating the lens barrel around the central axis, which can only meet the adaptation needs of a single person's interpupillary distance.

[0004] However, the existing components' tube spacing adjustment range is limited by the hinge axis's structural design, with the maximum spacing only covering single-person interpupillary distance adaptation, unable to be further expanded to meet the usage scenarios where two people each use one tube. This results in an excessively narrow tube spacing when two people use it simultaneously, leading to cramped and inconvenient observation postures, and even making it impossible to align both pupils simultaneously due to insufficient spacing, severely impacting the user experience and making it difficult to adapt to the needs of multiple people sharing the device, such as outdoor collaborative observation and teaching demonstrations. To address this, we propose a mechanical transmission adjustment component for telescopes. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mechanical transmission adjustment component for a telescope.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a mechanical transmission adjustment assembly for a telescope, comprising a first lens tube and a second lens tube, wherein a fixing block is fixedly installed on the side of the first lens tube, and adjusting arms are rotatably installed on both sides of the fixing block; a hinge seat is fixedly installed on the side of the second lens tube, and an extension rod is rotatably installed inside the hinge seat, and an adjustable assembly is provided at the end of the extension rod.

[0007] Preferably, a convex shaft extending from both sides of the fixing block is rotatably installed inside the fixing block, and the two ends of the fixing block are respectively fixed to the inner side of the two adjusting arms near one end. The inner side of the two adjusting arms near the other end is provided with a groove.

[0008] Preferably, the hinge seat has an opening groove on the side opposite to the second lens barrel, and a central shaft is fixedly connected between the inner walls of the two sides of the opening groove.

[0009] Preferably, one end of the extension rod is rotatably sleeved on the outer wall of the central shaft, and the other end of the extension rod is fixedly connected to a linkage shaft.

[0010] Preferably, the adjustable component includes a rotating rod and a steel ball. The rotating rod is rotatably sleeved at the end of the linkage shaft away from the extension rod. A spherical steel ball is fixedly connected to the end of the rotating rod, and the steel ball is movably connected between two grooves.

[0011] The beneficial effects of this utility model are: 1. When using this invention, the user holds the first and second lens tubes and adjusts the distance between them according to their pupillary distance requirements. During adjustment, the adjusting arms on both sides of the fixed block rotate flexibly around the convex axis, while the extension rod inside the hinge rotates around the central axis. This, combined with the sliding and rotation of the steel ball in the adjustable component within the groove of the adjusting arm, allows for smooth fine-tuning of the distance between the two lens tubes, adapting to a single person's standard pupillary distance range and ensuring clear binocular images and comfortable observation.

[0012] 2. When using this invention, if two people each need to use one telescope tube for observation, pulling the first and second telescope tubes in opposite directions to the sides will increase the distance between the two tubes. At this time, the adjusting arm rotates significantly around the convex axis, the steel ball slides synchronously in the groove and adjusts the angle, and the extension rod rotates around the central axis to a larger opening angle. Through the coordinated linkage of the three, the distance limitation of the central axis of the traditional hinge is overcome, allowing the distance between the two telescope tubes to be flexibly expanded according to the observation needs of two people, avoiding crowded postures, and ensuring that two people can simultaneously align their respective telescope tubes for observation.

[0013] 3. When using this utility model, if it is necessary to achieve bidirectional observation function with one tube observing the front and the other tube observing the rear, first pull the two tubes to rotate the extension and adjustment arms to a parallel state, then rotate the first or second tube forward or backward 180 degrees. During the rotation, the adjustment arm drives the steel ball to rotate synchronously. The steel ball rotates flexibly on the linkage shaft through the rotating rod, realizing the seamless switching of the tube rotation. Finally, the two tubes are arranged in opposite directions to meet the bidirectional observation needs in special scenarios. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1-4 As shown, a mechanical transmission adjustment assembly for a telescope is disclosed, comprising a first telescope tube 1 and a second telescope tube 2. A fixing block 10 is fixedly installed on the side of the first telescope tube 1, and adjusting arms 12 are rotatably installed on both sides of the fixing block 10. A hinge seat 3 is fixedly installed on the side of the second telescope tube 2, and an extension rod 6 is rotatably installed inside the hinge seat 3. An adjustable component is provided at the end of the extension rod 6.

[0019] The fixed block 10 is rotatably mounted with protruding shafts 11 extending from both sides of the fixed block 10. The two ends of the fixed block 10 are respectively fixed to the inner side of the two adjusting arms 12 near one end. The inner side of the two adjusting arms 12 near the other end is provided with grooves 13. When in use, hold the first lens tube 1 and the second lens tube 2 and adjust the distance between the two lens tubes according to your own pupillary distance requirements. During the adjustment process, the adjusting arms 12 on both sides of the fixed block 10 rotate flexibly around the protruding shafts 11. At the same time, the extension rod 6 in the hinge 3 rotates around the central axis 5 as the fulcrum. With the sliding and rotation of the steel ball 9 in the adjustable component in the groove 13 of the adjusting arm 12, the distance between the two lens tubes can be smoothly finely adjusted to adapt to the normal pupillary distance range of a single person, ensuring clear binocular images and comfortable observation.

[0020] The hinge 3 has an opening groove 4 on the side opposite to the second lens tube 2, and a central shaft 5 is fixed between the inner walls of the two sides of the opening groove 4.

[0021] One end of the extension rod 6 is rotatably sleeved on the outer wall of the central shaft 5, and the other end of the extension rod 6 is fixedly connected to the linkage shaft 7. If it is necessary to realize the bidirectional observation function of one tube observing the front and the other tube observing the rear, first pull the two tubes to rotate the extension rod 6 and the adjusting arm 12 to a parallel state, and then flip the first tube 1 or the second tube 2 forward or backward by 180 degrees. During the flipping process, the adjusting arm 12 drives the steel ball 9 to rotate synchronously. The steel ball 9 rotates flexibly on the linkage shaft 7 through the rotating rod 8, realizing the seamless switching of the tube rotation, and finally achieving the front and rear reverse arrangement of the two tubes to meet the bidirectional observation needs in special scenarios.

[0022] The adjustable assembly includes a rotating rod 8 and a steel ball 9. The rotating rod 8 is rotatably connected to the end of the linkage shaft 7 opposite to the end of the extension rod 6. The end of the rotating rod 8 is fixedly connected to a spherical steel ball 9, which is movably connected between two grooves 13. When two people need to use one telescope each, they can pull the first telescope 1 and the second telescope 2 in opposite directions to widen the distance between the two telescopes. At this time, the adjusting arm 12 rotates significantly around the convex shaft 11, and the steel ball 9 slides synchronously in the groove 13 and adjusts its angle. The extension rod 6 rotates around the central axis 5 to a larger opening angle. By allowing the distance between the two telescopes to be flexibly expanded according to the observation needs of two people, crowded postures are avoided, and it is ensured that two people can simultaneously align their respective telescopes for observation.

[0023] Working principle: When used by a single person; hold the first lens tube 1 and the second lens tube 2, and adjust the distance between the two lens tubes according to your own pupillary distance requirements. During the adjustment process, the adjustment arms 12 on both sides of the fixed block 10 rotate flexibly around the convex shaft 11. At the same time, the extension rod 6 in the hinge 3 rotates around the central axis 5 as the fulcrum. With the sliding and rotation of the steel ball 9 in the adjustable component in the groove 13 of the adjustment arm 12, the distance between the two lens tubes can be smoothly and finely adjusted to adapt to the normal pupillary distance range of a single person, ensuring clear binocular images and comfortable observation. When used by two people, if each person needs to use one microscope tube for observation, they can pull the first microscope tube 1 and the second microscope tube 2 in opposite directions to widen the distance between the two tubes. At this time, the adjusting arm 12 rotates significantly around the convex shaft 11, the steel ball 9 slides synchronously in the groove 13 and adjusts the angle, and the extension rod 6 rotates around the central axis 5 to a larger opening angle. Through the coordinated linkage of the three, the distance between the two microscope tubes can be flexibly expanded according to the observation needs of the two people, avoiding crowded postures and ensuring that the two people can simultaneously align their respective microscope tubes for observation. For bidirectional observation, if it is necessary to achieve the bidirectional observation function of one tube observing the front and the other tube observing the rear, first pull the two tubes to rotate the extension rod 6 and the adjusting arm 12 to a parallel state. Then, rotate the first tube 1 or the second tube 2 forward or backward by 180 degrees. During the rotation, the adjusting arm 12 drives the steel ball 9 to rotate synchronously. The steel ball 9 rotates flexibly on the linkage shaft 7 through the rotating rod 8, realizing the seamless switching of the tube rotation and achieving the arrangement of the two tubes in opposite directions to meet the bidirectional observation requirements in special scenarios.
