Description

Technical Field

[0001] This invention relates to the field of optical instrument technology, specifically to a large field-of-view Porro type independent focusing binoculars. Background Technology

[0002] The Porro prism structure uses two prisms at 90° to each other. This structure folds the light path, allowing the telescope to achieve a longer optical path in a shorter length. After light enters the telescope tube through the objective lens, it is reflected by the Porro prism, changing its propagation direction, and finally enters the eyepiece to form an upright image. Compared to roof prisms, Porro prisms have a relatively simple structure and lower cost, providing better optical performance at the same price point; however, they are usually larger and heavier.

[0003] Patent application CN03230307.6 discloses a binocular telescope with a digital camera, including a lens mount, a CMOS chip housed within the lens mount, and an objective lens coaxial with the CMOS chip. The objective lens is mounted in a lens barrel threaded into the lens mount, and a focusing dial is fixed to the lens barrel. In use, the distance between the objective lens and the CMOS chip is adjusted by moving the focusing dial to obtain a clear image.

[0004] However, this patent also has the following drawbacks: the independent focusing structure makes the internal layout of the telescope more complex, requiring more space to accommodate the focusing components, resulting in an increase in the size and weight of the telescope. This affects portability, and users will find it more strenuous in scenarios requiring long-term handheld observation or long-distance outdoor treks. For example, when used at mountain viewpoints, an excessively heavy telescope can become a burden. To address this issue, a large-field-of-view Porro type independent focusing binoculars is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a large field-of-view Porro type independent focusing binoculars to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a wide field-of-view Porro type independent focusing binoculars, including a telescope tube, a focusing device rotatably connected to the inner wall of the telescope tube, a lens ring fixedly connected to the right side of the telescope tube, an eyepiece fixedly connected to the left side of the telescope tube, a mounting block fixedly connected to the surface of the lens ring, protective covers rotatably connected to both sides of the inner wall of the mounting block via a rotating shaft, a telescopic mechanism provided on the surface of the telescope tube, a folding mechanism provided at the bottom of the telescope tube, and further comprising: The cleaning assembly includes a mounting plate slidably connected to the inner wall of a protective cover. A movable ring is rotatably connected to the inner wall of the mounting plate via a pivot. A telescopic plate is slidably connected to the top slot of the movable ring. Rotating frames are rotatably connected to both sides of the inner wall of the movable ring via pivots. A snap-fit ​​cavity is fixedly connected to the bottom of the movable ring. A connecting arm is fixedly connected to the inner wall of the rotating frame. A cleaning film is fixedly connected to the top of the connecting arm. The movable ring is used to rotate on the inner wall of the mounting plate, and the cleaning film on the surface of the connecting arm wipes away water droplets on the lens surface.

[0007] According to the above technical solution, the telescopic mechanism includes a telescopic plate, which is adsorbed and fixed to the surface of the telescope tube. A movable rod is fixedly connected to one side of the inner wall of the telescopic plate, and a connecting frame is fixedly connected to the surface of the telescopic plate. One end of the mounting tube extends and retracts from the surface of the movable rod to the inner wall of the telescopic plate.

[0008] The pulling assembly includes a mounting tube slidably connected to one end of a movable rod. A pulling plate is fixedly connected to the surface of the mounting tube. The pulling plate slides in contact with the inner wall of a telescopic plate. A pressing groove is formed on the surface of the pulling plate. A pulling rope is fixedly connected to the end of the mounting tube away from the movable rod. A covering frame is fixedly connected to the end of the pulling rope away from the mounting tube. The covering frame engages with the surface of a protective cover. By pulling the pressing groove, the pulling plate moves in the direction of the pulling rope.

[0009] According to the above technical solution, the mounting tube is slidably connected to the inner wall of the telescopic plate, and two telescopic plates are provided. The two telescopic plates are installed on both sides of the telescope tube. The two ends of the connecting frame are fixedly connected to the surface of the telescopic plate. The bottom of the covering frame is fixedly connected to one end of the mounting plate through the inner wall of the protective cover. By pulling the pulling plate, the pulling plate drives the mounting tube to slide and extend on the surface of the movable rod.

[0010] According to the above technical solution, the folding mechanism includes a storage plate, which is fixedly connected to the bottom of the telescope tube. The two sides of the storage plate are rotatably connected to a tension frame via a pivot. A connecting rod is fixedly connected to the end of the tension frame away from the storage plate. A placement plate is rotatably connected to the surface of the connecting rod. A pull bolt is fixedly connected to the surface of the tension frame. A locking post is slidably connected to the inner wall of the placement plate. A locking assembly is provided at the bottom of the placement plate. When the tension frame drives the placement plate to extend and retract outward to the required angle, the placement plate will come into contact with the slope.

[0011] The support assembly includes a storage tube fixedly connected to the inner wall of a storage plate, a telescopic column slidably connected to the inner wall of the storage tube, a support frame fixedly connected to the end of the telescopic column away from the storage tube, a receiving block fixedly connected to the bottom of the storage plate, lifting arms rotatably connected to both sides of the inner wall of the receiving block via pivots, one end of the lifting arm fixedly connected to the surface of the telescopic column, support feet rotatably connected to both sides of the inner wall of the lifting arm via pivots, and a pull ring fixedly connected to the surface of the telescopic column. The lifting arms support the telescopic column, preventing it from being pushed into the storage tube by pressure from the top telescope.

[0012] According to the above technical solution, the support frame has insertion holes at both ends, and the two ends of the support frame are inserted and fixed to one end of the locking post. The pressure generated by the telescope on the two ends of the support frame will cause the locking post to extend and retract towards the inner wall of the placement plate.

[0013] According to the above technical solution, the snap-fit ​​assembly includes a support block, which is fixedly connected to the bottom of the placement plate. An ejector tube is fixedly connected to the bottom of the inner wall of the support block. A shrink ring is fixedly connected to the end of the ejector tube away from the inner wall of the support block. A plug-in block is fixedly connected to the surface of the shrink ring. One end of the plug-in block is rotatably connected to both sides of the inner wall of the support block through a rotating shaft. When the shrink ring squeezes the support block, one end of the plug-in block will be subjected to force and gradually loosen from the snap-fit ​​groove on the inner wall of the support block.

[0014] According to the above technical solution, the ejector tube has compressibility, the shrink ring has stretchability, the surface of the plug block is fixedly connected with a hook block, and one end of the ejector tube extends and retracts outward to push the shrink ring.

[0015] According to the above technical solution, a snap-fit ​​block is fixedly connected to the surface of the rotating frame, and a snap-fit ​​groove is opened on the surface of the snap-fit ​​cavity. When the rotating frame drives the connecting arm to rotate vertically to the bottom by 90 degrees, the installation plate can be smoothly removed from the inner wall of the protective cover.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention features a folding mechanism that uses the bottom insertion hole of the support leg to connect and fix it to the locking block on the inner wall of the receiving block. This allows the telescopic column to be supported by the raised arm, preventing it from being pushed into the storage tube by the pressure from the top telescope and thus failing to support the telescope. With this mechanism, when users need to use the focusing telescope outdoors for extended periods, the telescope can be supported, and the observation angle of the telescope can be freely adjusted, preventing users from feeling tired from using the focusing telescope for a long time.

[0017] 2. By setting up a snap-fit ​​component, when the plug-in block is completely separated from the inner wall of the support block, the elasticity of the ejector tube itself will cause the plug-in block to pop outward. At this time, the hook on the surface of the plug-in block will insert into the soil, thereby quickly fixing the telescope inside the slope. By setting up this component, the telescope and the observation position can be quickly fixed to ensure the stability of the telescope during observation.

[0018] 3. By setting up a cleaning component, when the movable ring drives the connecting arm to rotate inside the lens ring, the cleaning film on the surface of the connecting arm will wipe away the water droplets on the lens surface. By setting up this component, water droplets inside the lens ring can be quickly removed without affecting the observation position of the telescope, and the cleaning efficiency of the lens inside the lens ring can be improved.

[0019] 4. By incorporating a pulling component, this invention allows the mounting plate to be easily removed from the inner wall of the protective cover when the rotating frame drives the connecting arm to rotate vertically to the bottom by 90 degrees. Finally, the protective cover is simply pushed so that one end rotates downwards on the inner wall of the mounting block. Once the protective cover reaches the surface of the lens ring, it is inserted and fixed to the surface of the lens ring. This component facilitates the cleaning of water droplets from the lens surface inside the lens ring without affecting the subsequent storage and use of the telescope. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0024] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0025] Example 1: See Figures 1-5This invention provides a technical solution: a wide-field-of-view Porro type independent focusing binoculars, including a telescope tube 1, a focusing device 2 rotatably connected to the inner wall of the telescope tube 1, a lens ring 3 fixedly connected to the right side of the telescope tube 1, an eyepiece 4 fixedly connected to the left side of the telescope tube 1, a mounting block 6 fixedly connected to the surface of the lens ring 3, protective covers 5 rotatably connected to both sides of the inner wall of the mounting block 6 via a rotating shaft, a telescopic mechanism 8 provided on the surface of the telescope tube 1, and a folding mechanism 7 provided at the bottom of the telescope tube 1, and further comprising: The telescopic mechanism 8 includes a telescopic plate 801, which is magnetically fixed to the surface of the telescope tube 1. Eight sets of neodymium iron boron permanent magnets 8011 are evenly distributed on the inner side of the telescopic plate 801, forming a magnetic attraction with the 304 stainless steel coating 101 on the surface of the telescope tube 1, with an attraction force ≥50N. A movable rod 802 is fixedly connected to one side of the inner wall of the telescopic plate 801, and a connecting frame 803 is fixedly connected to the surface of the telescopic plate 801. When the user uses the focusing telescope to observe the observation point for a long time, the lens surface inside the lens ring 3 of the telescope will be covered with a layer of water droplets due to the humid environment in the field.

[0026] The pulling assembly 804 includes a mounting tube 8042 slidably connected to one end of a movable rod 802. A pulling plate 8041 is fixedly connected to the surface of the mounting tube 8042. The pulling plate 8041 slides in contact with the inner wall of the telescopic plate 801. A pressing groove 8043 is formed on the surface of the pulling plate 8041. A pulling rope 8044 is fixedly connected to the end of the mounting tube 8042 away from the movable rod 802. A covering frame 8045 is fixedly connected to the end of the pulling rope 8044 away from the mounting tube 8042. The covering frame 8045 is engaged with the surface of the protective cover 5. The user simply inserts their middle finger into the push groove 8043 and pulls the push groove 8043, causing the pull plate 8041 to move towards the pull rope 8044. By pulling the pull plate 8041, the pull plate 8041 causes the mounting tube 8042 to slide and extend on the surface of the movable rod 802. At this time, one end of the mounting tube 8042 will slide on the inner wall of the telescopic plate 801 and push the pull rope 8044, so that one end of the pull rope 8044 is subjected to force and pushes the covering frame 8045.

[0027] The mounting tube 8042 is slidably connected to the inner wall of the telescopic plate 801. Two telescopic plates 801 are provided, and the two telescopic plates 801 are installed on both sides of the telescope tube 1. The two ends of the connecting frame 803 are fixedly connected to the surface of the telescopic plate 801. The bottom of the covering frame 8045 is fixedly connected to one end of the mounting plate 901 through the inner wall of the protective cover 5. When the covering frame 8045 pushes the protective cover 5, it will drive one end of the protective cover 5 to rotate downward on the inner wall of the mounting block 6. When the protective cover 5 rotates to the surface of the lens ring 3, the lens inside the lens ring 3 will squeeze the telescopic plate 902, causing the telescopic plate 902 to be stressed and extend into the movable ring 903, thereby activating the controller switch inside the movable ring 903. This will drive the movable ring 903 to rotate on the inner wall of the mounting plate 901. When the movable ring 903 drives the connecting arm 906 to rotate inside the lens ring 3, the cleaning film 907 on the surface of the connecting arm 906 will wipe away the water droplets on the surface of the lens.

[0028] The cleaning component 9 includes a mounting plate 901 that slides along the inner wall of the protective cover 5. A movable ring 903 is rotatably connected to the inner wall of the mounting plate 901 via a pivot. A telescopic plate 902 is slidably connected to the top slot of the movable ring 903. Rotating frames 905 are rotatably connected to both sides of the inner wall of the movable ring 903 via pivots. A snap-fit ​​cavity 904 is fixedly connected to the bottom of the movable ring 903. A connecting arm 906 is fixedly connected to the inner wall of the rotating frame 905. A cleaning membrane 907 is fixedly connected to the top of the connecting arm 906. The cleaning membrane 907 is made of antibacterial polyurethane sponge, 2mm thick, with a silica nano-coating impregnated on the surface to enhance water absorption. The cleaning membrane 907 is quickly connected to the connecting arm 906 via Velcro 9061, allowing for one-handed disassembly and replacement. The movable ring 903 is used to rotate on the inner wall of the mounting plate 901. When the pull plate 8041 is pulled towards the eyepiece 4, the telescopic disc 902 on the surface of the protective cover 5 will come into contact with the inner lens of the lens ring 3. The bottom of the telescopic disc 902 is equipped with a telescopic spring. When the surface of the telescopic disc 902 is no longer pressed, it will pop outward. At this time, the internal controller switch of the movable ring 903 will stop operating when it is no longer pressed. This allows for the rapid removal of water droplets from the inner lens of the lens ring 3 without affecting the observation position of the telescope, and improves the cleaning efficiency of the inner lens of the lens ring 3.

[0029] A snap-fit ​​block is fixedly connected to the surface of the rotating frame 905, and a snap-fit ​​groove is opened on the surface of the snap-fit ​​cavity 904. When the telescope needs to be placed after use, the lens ring 3 needs to be protected. First, pull the cover frame 8045 out of the surface of the protective cover 5. Then, by holding the push groove 8043 with your fingers, pull the pull plate 8041 towards the eyepiece 4. The mounting tube 8042 slides and extends on the surface of the movable rod 802. When one end of the mounting tube 8042 extends and retracts on the surface of the movable rod 802 to the inner wall of the telescopic plate 801, one end of the pull rope 8044 will pull the mounting plate 901. This will cause the mounting plate 901 to be pulled out from the through hole on the surface of the protective cover 5. The connecting arm 906 will rotate the rotating frame 905 to the bottom due to contact with the inner wall of the protective cover 5. At this time, the locking block on the surface of the rotating frame 905 will be disengaged from the inside of the locking cavity 904. After the rotating frame 905 drives the connecting arm 906 to rotate vertically to the bottom by 90 degrees, the mounting plate 901 can be easily removed from the inner wall of the protective cover 5. Finally, the protective cover 5 only needs to be pushed so that one end of the protective cover 5 rotates downward on the inner wall of the mounting block 6. After the protective cover 5 rotates to the surface of the lens ring 3, it is fixed by inserting the protective cover 5 into the surface of the lens ring 3. This facilitates the cleaning of water droplets on the surface of the lens inside the lens ring 3 without affecting the subsequent storage and use of the telescope.

[0030] Example 2: Based on Example 1, please refer to the following... Figures 6-7 The present invention provides a technical solution: the folding mechanism 7 includes a storage plate 701, which is fixedly connected to the bottom of the telescope tube 1. The two sides of the storage plate 701 are rotatably connected to a tension frame 702 via a pivot. A connecting rod 704 is fixedly connected to the end of the tension frame 702 away from the storage. A placement plate 703 is rotatably connected to the surface of the connecting rod 704. A pull bolt 705 is fixedly connected to the surface of the tension frame 702. A locking post 706 is slidably connected to the inner wall of the placement plate 703. A locking assembly 708 is provided at the bottom of the placement plate 703. When the user needs to use the focusing telescope for long-term observation outdoors, the complex internal structure of the focusing telescope may cause the user to feel strained. At this time, the user can pull the pull bolt 705 with their fingers to pull the tension frame 702 downward, so that the tension frame 702 drives the placement plate 703 to extend and retract from the inside of the storage plate 701 to the bottom. When the tension frame 702 drives the placement plate 703 to extend and retract outward to the required angle, the placement plate 703 will come into contact with the slope.

[0031] The support assembly 707 includes a storage tube 7071 fixedly connected to the inner wall of the storage plate 701. A telescopic column 7072 is slidably connected to the inner wall of the storage tube 7071. A support frame 7077 is fixedly connected to the end of the telescopic column 7072 away from the storage tube 7071. A receiving block 7073 is fixedly connected to the bottom of the storage plate 701. Lifting arms 7074 are rotatably connected to both sides of the inner wall of the receiving block 7073 via pivots. One end of the lifting arm 7074 is fixedly connected to the surface of the telescopic column 7072. Support feet 7075 are rotatably connected to both sides of the inner wall of the lifting arm 7074 via pivots. A pull ring 7076 is fixedly connected to the surface of the telescopic column 7072. The telescopic column 7072 can be moved from the storage plate 701 by pulling the pull ring 7076 with a finger. When the telescopic column 7072 extends from the inside of the storage tube 7071 to the top, it will cause the support frame 7077 at the top to come into contact with the top of the placement plate 703. The support frame 7077 is inserted and fixed to the surface of the snap-fit ​​column 706 through the insertion holes at both ends. At the same time, when the telescopic column 7072 extends to the top, the lifting arm 7074 on the surface of the telescopic column 7072 will move upward and disengage from the inside of the receiving block 7073. Then, the support foot 7075 is pulled out from the inner wall of the lifting arm 7074, so that one end of the support foot 7075 rotates outward to the bottom of the inner wall of the receiving block 7073. The support foot 7075 is inserted and fixed to the snap-fit ​​block on the inner wall of the receiving block 7073 through the insertion hole at the bottom of the support foot 7075.

[0032] The support frame 7077 has insertion holes at both ends. The two ends of the support frame 7077 are inserted and fixed to one end of the locking post 706. The telescopic post 7072 is supported by the lifting arm 7074 to prevent the telescopic post 7072 from being stretched into the storage tube 7071 due to pressure from the top telescope, thus failing to support the telescope. When the user needs to use the focusing telescope for observation for a long time outdoors, the telescope can be supported by this mechanism, and the observation angle of the telescope can be freely adjusted to avoid the user feeling tired when using the focusing telescope for a long time.

[0033] Example 3: Based on Example 2, please refer to the following... Figure 8 The present invention provides the following technical solution: The snap-fit ​​assembly 708 includes a base block 7081, which is fixedly connected to the bottom of the placement plate 703. An ejector tube 7082 is fixedly connected to the bottom inner wall of the base block 7081. The ejector tube 7082 is made of 304 stainless steel corrugated pipe with a wall thickness of 0.1mm, a compression stroke of 15mm, and is filled with silicone oil to achieve damping and reset. A contraction ring 7083 is fixedly connected to the end of the ejector tube 7082 away from the inner wall of the base block 7081. A plug-in block 7084 is fixedly connected to the surface of the contraction ring 7083. One end of the plug-in block 7084 is rotatably connected to both sides of the inner wall of the base block 7081 via a pivot. When both ends of the support frame 7077 are inserted and fixed to the surface of the snap-fit ​​post 706, the pressure generated by the telescope on both ends of the support frame 7077 will cause the snap-fit ​​post 706 to move inwards towards the inner wall of the placement plate 703. The wall extends and retracts. When the locking post 706 extends and retracts towards the inner wall of the placement plate 703, it pushes the ejection tube 7082. This causes one end of the ejection tube 7082 to extend and retract outward and push the contraction ring 7083. One end of the insertion block 7084 is inserted into the inner wall of the support block 7081. When the contraction ring 7083 squeezes the support block 7081, one end of the insertion block 7084 will be subjected to force and gradually loosen from the inner wall slot of the support block 7081.

[0034] The ejector tube 7082 has compressibility, the contraction ring 7083 has stretchability, and the surface of the insertion block 7084 is fixedly connected with hooks. When the insertion block 7084 is completely separated from the inner wall of the support block 7081, the ejector tube 7082 will cause the insertion block 7084 to pop outward due to its own elastic reset function. At this time, the hooks on the surface of the insertion block 7084 will insert into the soil, thereby quickly fixing the telescope inside the slope. This allows for quick fixation of the telescope to the observation position to ensure the stability of the telescope during observation.
