Description

Technical Field

[0001] This utility model relates to a connecting device, specifically a connecting device for a telescope barrel accessory, belonging to the field of telescope technology. Background Technology

[0002] A telescope is an optical instrument that uses lenses or mirrors and other optical components to observe distant objects. It works by using the refraction of light through a lens or the reflection of light by a concave mirror to make the light enter a small aperture and converge to form an image, which is then seen through a magnifying eyepiece. It is also known as a "telescope". In our daily lives, the most commonly used type is binoculars, which are made by connecting two tubes together with aluminum alloy fittings.

[0003] According to the patent disclosed in patent number CN115032783A, a multifunctional telescope and its usage method can effectively improve the quality and efficiency of power transmission line operation and maintenance inspections and enhance the level of power grid safety operation and maintenance. The device has a reasonable and compact structure and is easy to use, providing strong reference and guidance for the application of telescopes in the field of power transmission line operation and maintenance.

[0004] When using binoculars, the distance between the eyes varies among different people. To ensure that binoculars can be used by all, the connecting device for the binocular barrels is often rotatable. By rotating the two barrels, the distance between them is adjusted to match the user's eye distance. Since the aluminum alloy connecting device in this method positions the adjusted barrels based on the frictional resistance between the aluminum alloys, over time, the coefficient of friction between the aluminum alloys decreases, making it less effective at positioning the adjusted barrels and inconvenient for users. Therefore, we provide a binocular barrel connecting device to solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a connecting device for telescope tube accessories in order to solve the above-mentioned problems, thereby addressing the issue that the existing technology cannot better position the adjusted tube.

[0006] This utility model is achieved through the following technical solution: a connecting device for a telescope tube accessory, comprising an aluminum alloy box and an aluminum alloy block, wherein the outer surface of the aluminum alloy block is provided with equidistantly arranged limiting grooves, and the interior of the aluminum alloy box is provided with a positioning mechanism, the positioning mechanism comprising a sliding plate, wherein a limiting plate is fixedly connected to the side of the sliding plate near the aluminum alloy block, and two springs are fixedly connected to the side of the sliding plate away from the aluminum alloy block, both springs being fixedly connected to the inner wall of the aluminum alloy box, wherein a connecting rod is fixedly connected to the side of the sliding plate away from the aluminum alloy block, and a fixing cylinder is slidably connected to the outer surface of the connecting rod, the fixing cylinder being fixedly connected to the inner wall of the aluminum alloy box.

[0007] Furthermore, the sliding plate is slidably connected to the inner wall of the aluminum alloy box, the limiting plate is slidably connected to the aluminum alloy box and extends to the outside of the aluminum alloy box, the limiting plate is adapted to the limiting groove, and the aluminum alloy block can be limited by inserting the limiting plate into the limiting groove.

[0008] Furthermore, connecting blocks are fixedly connected to both sides of the sliding plate, and handles are fixedly connected to the ends of the two connecting blocks that are far apart from each other. By setting the handles, people can easily slide the connecting blocks, and the sliding plate can be driven to slide as the connecting blocks slide.

[0009] Furthermore, a fixed shaft is fixedly connected to the inner wall of the aluminum alloy box, and the aluminum alloy block is rotatably connected to the outer surface of the fixed shaft. By providing a rotatable connection between the aluminum alloy block and the fixed shaft, the aluminum alloy block can rotate.

[0010] Furthermore, the aluminum alloy box and the aluminum alloy block are both fixedly connected to the lens barrel body on their opposite sides, and the outer surfaces of the two lens barrel bodies are fixedly connected to the fixing rings. The rotational connection between the aluminum alloy block and the fixing shaft enables the two lens barrel bodies to rotate.

[0011] Furthermore, a protective cover 1 is hinged to the upper surface of each of the two lens barrel bodies, a protective cover 2 is hinged to the bottom surface of each of the two lens barrel bodies, and magnetic rings are fixedly connected to both the upper and lower ends of the lens barrel bodies. Both the protective cover 1 and the protective cover 2 are made of iron.

[0012] Furthermore, the aluminum alloy box is equipped with a hanging rope on the outside, with each end of the hanging rope being fixedly connected to two fixing rings. The hanging rope allows people to hang the device around their necks for easy carrying.

[0013] Compared with the prior art, the connecting device for a telescope tube accessory has the following advantages: 1. This utility model, through the cooperative arrangement of the aluminum alloy box, aluminum alloy block, limiting groove and positioning mechanism, enables people to no longer rely on the frictional resistance between aluminum alloys to position the adjusted lens barrel.

[0014] 2. This utility model, through the cooperative arrangement of protective cover one, protective cover two, and the lens barrel body, enables the device to protect the lens of the lens barrel body when not in use. During the non-use period, by rotating protective cover one and protective cover two, the protective cover one and protective cover two can be attracted to the lens barrel body under the action of the magnetic rings fixed at the upper and lower ends of the lens barrel body, thereby achieving protection of the upper and lower lenses of the lens barrel body and making it convenient for people to use.

Detailed Implementation

[0017] This embodiment provides a connecting device for a telescope barrel accessory.

[0018] Example 1: The device, through the coordinated arrangement of aluminum alloy box 1, aluminum alloy block 2, limiting groove 3 and positioning mechanism 4, enables people to position the adjusted lens barrel without relying on the frictional resistance between the aluminum alloys. This effectively avoids the situation where the adjustment of the lens barrel cannot be properly positioned due to the decrease in the coefficient of friction between the aluminum alloys during long-term use, making it more convenient for people to use.

[0019] See Figure 1 , Figure 3 and Figure 4 A connecting device for a telescope tube accessory includes an aluminum alloy box 1 and an aluminum alloy block 2. Both the aluminum alloy box 1 and the aluminum alloy block 2 are made of aluminum alloy. The outer surface of the aluminum alloy block 2 is provided with equidistant limiting grooves 3 arranged in a circular array.

[0020] Example 2: The aluminum alloy box 1 is equipped with a positioning mechanism 4. The positioning mechanism 4 includes a sliding plate 401. A limiting plate 402 is fixedly connected to the side of the sliding plate 401 near the aluminum alloy block 2. The limiting plate 402 is pentagonal in shape. Two springs 403 are fixedly connected to the side of the sliding plate 401 away from the aluminum alloy block 2. The springs 403 have a large elastic coefficient to ensure that the limiting plate 402 can be in close contact with the aluminum alloy block 2.

[0021] Both springs 403 are fixedly connected to the inner wall of the aluminum alloy box 1. A connecting rod 404 is fixedly connected to the side of the sliding plate 401 away from the aluminum alloy block 2. A fixed cylinder 405 is slidably connected to the outer surface of the connecting rod 404. The movement of the sliding plate 401 can drive the connecting rod 404 to move inward or outward from the fixed cylinder 405. The fixed cylinder 405 is fixedly connected to the inner wall of the aluminum alloy box 1.

[0022] The sliding plate 401 is slidably connected to the inner wall of the aluminum alloy box 1, and the limiting plate 402 is slidably connected to the aluminum alloy box 1 and extends to the outside of the aluminum alloy box 1. The limiting plate 402 is adapted to the limiting groove 3. By inserting the limiting plate 402 into the limiting groove 3, the aluminum alloy block 2 can be limited.

[0023] Connecting blocks 406 are fixedly connected to both sides of the sliding plate 401. Handles 407 are fixedly connected to the ends of the two connecting blocks 406 that are far apart from each other. By setting the handles 407, people can slide the connecting blocks 406 more conveniently. As the connecting blocks 406 slide, the sliding plate 401 can be driven to slide. The connecting blocks 406 extend to the outside of the aluminum alloy box 1 and are slidably connected to the aluminum alloy box 1.

[0024] Example 3: See Figure 1 and Figure 2 A fixed shaft 5 is fixedly connected to the inner wall of the aluminum alloy box 1, and an aluminum alloy block 2 is rotatably connected to the outer surface of the fixed shaft 5. The aluminum alloy block 2 can be rotated by the rotatable connection between the aluminum alloy block 2 and the fixed shaft 5. Lens tube bodies 6 are fixedly connected to the opposite sides of the aluminum alloy box 1 and the aluminum alloy block 2. Fixing rings 7 are fixedly connected to the outer surfaces of the two lens tube bodies 6. The rotatable connection between the aluminum alloy block 2 and the fixed shaft 5 allows the two lens tube bodies 6 to be rotated, thereby adjusting the distance between the two lens tube bodies 6 to a distance that is compatible with the distance between the user's eyes.

[0025] The upper surfaces of the two lens barrel bodies 6 are hinged with protective covers 1 8, and the bottom surfaces of the two lens barrel bodies 6 are hinged with protective covers 2 9. Magnet rings are fixedly connected to both the upper and lower ends of the lens barrel body 6. Both protective covers 1 8 and protective covers 2 9 are made of iron. Through the action of the magnet rings, protective covers 1 8 and protective covers 2 9 can be attracted to the upper and lower ends of the lens barrel body 6, thereby protecting the upper and lower lenses of the lens barrel body 6.

[0026] The aluminum alloy box 1 is equipped with a hanging rope 10 on the outside. The two ends of the hanging rope 10 are fixedly connected to two fixing rings 7 respectively. By setting the hanging rope 10, people can hang the device around their necks for easy carrying.

[0027] Working Principle: During the use of this device, when it is necessary to adjust the distance between the two lens barrel bodies 6, firstly, the connecting block 406 is slid along the handle 407. As the connecting block 406 slides, it drives the sliding plate 401 to slide, which in turn drives the limiting plate 402 to slide until the limiting plate 402 disengages from the limiting groove 3. At this point, the spring 403 is compressed. Then, the two lens barrel bodies 6 are rotated. As the lens barrel bodies 6 rotate, the aluminum alloy block 2 rotates, thereby rotating the limiting groove 3 at different positions. When the distance between the two lens barrel bodies 6 is adjusted to match the distance between the user's eyes, the two handles 407 are released. Under the action of the spring 403, the sliding plate 401 is reset, and the limiting plate 402 is inserted into the limiting groove 3. This achieves the positioning of the two lens barrel bodies 6 after adjustment, effectively avoiding the situation where the friction coefficient between the aluminum alloy decreases during long-term use, which would prevent proper positioning of the adjusted lens barrels. This makes it convenient for users. The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
