Description

Technical Field

[0001] This utility model relates to the field of telescope technology, and in particular to a portable binoculars. 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 create an image that is then seen through a magnifying eyepiece; it is also known as a telescope.

[0003] The first function of a telescope is to magnify the angular size of distant objects, allowing the human eye to see details with smaller angular distances. The second function of a telescope is to send a beam of light, collected by the objective lens and much wider than the diameter of the pupil (maximum 8 mm), into the human eye, enabling the observer to see faint objects that were previously invisible.

[0004] Existing telescopes have the following drawbacks in practical use:

[0005] However, existing telescopes cannot provide adequate protection when dropped or bumped during transport, which can easily damage the objective lens and eyepiece, causing unnecessary economic losses and shortening the telescope's lifespan. Utility Model Content

[0024] The following is in conjunction with the appendix Figures 1-4 The present invention will be further described below.

[0025] To address the problems existing in the background art, this application proposes the following technical solution: a portable binoculars.

[0026] The specific technical solution includes a telescope body 1, with a protective mechanism 4 on one side of the telescope body 1. The protective mechanism 4 includes an eyepiece cover 2, an objective lens cover 3, and a fixed shell 11. The fixed shell 11 is located on one side of the telescope body 1, and a cavity 12 is formed inside the fixed shell 11. A rotating shaft 17 is rotatably installed in the cavity 12. The rotating shaft 17 is rotatably installed between the inner walls of the cavity 12 via bearings. A gear 16 is fixedly installed around the rotating shaft 17. Connecting blocks 13 are fixedly installed on one side of both the eyepiece cover 2 and the objective lens cover 3. The two connecting blocks 13 are located on both sides of the fixed shell 11. A toothed plate 15 is fixedly installed on one side of each of the two connecting blocks 13. The toothed plate 15 is slidably installed on one side of the inner wall of the cavity 12. The toothed plate 15 is slidably connected to the inner wall of the cavity 12 via a slide rail and a slider. Both toothed plates 15 mesh with the gear 16. The two toothed plates 15 are located on both sides of the gear 16. A turbine 18 is fixedly installed on the 7th side, and a worm gear 19 is rotatably installed in the cavity 12. The worm gear 19 meshes with the turbine 18. An operating knob 20 is fixedly installed at one end of the worm gear 19. The operating knob 20 is located on one side of the fixed shell 11 and is tightly fitted to one side of the fixed shell 11. The tight fit between the operating knob 20 and one side of the fixed shell 11 creates friction between the operating knob 20 and the fixed shell 11, preventing the operating knob 20 from being accidentally turned. The telescope body 1 includes a shell 6, a tube 7, an eyepiece 8, and an objective lens 9. There are two tubes 7, two eyepieces 8, and two objective lenses 9. The two tubes 7 are fixedly installed on both sides of the shell 6. The eyepiece 8 is located at one end of the tube 7, and the objective lens 9 is located at the other end of the tube 7. The eyepiece 8 and the objective lens 9 correspond to each other. The eyepiece cover 2 is fitted around the two eyepieces 8, and the objective lens cover 3 is fitted around the two objective lenses 9.

[0027] Reference Figure 1 and Figure 4 As shown, a fixing plate 21 is fixedly installed on both sides of the fixing shell 11. A hanging rope 5 is provided between the two fixing plates 21. The hanging rope 5 is located around the fixing shell 11 and is close to the eyepiece cover 2. A plug-in post 23 is fixedly installed at both ends of the hanging rope 5. A plug-in slot 22 is provided on one side of the fixing plate 21. The plug-in post 23 is plugged into the plug-in slot 22. A threaded groove 25 is provided on the periphery of one end of the plug-in post 23. A threaded cylinder 24 is threadedly installed on one end of the plug-in post 23 through the threaded groove 25. The threaded cylinder 24 and the plug-in post 23 are located on both sides of the fixing plate 21. By unscrewing the threaded cylinder 24 and disengaging the plug-in post 23 from the plug-in slot 22, the hanging rope 5 can be removed, making it convenient for the user to replace or clean the hanging rope 5.

[0028] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0029] In use, when assembling the telescope body 1 with the eyepiece cover 2 and objective lens cover 3, the telescope body 1 is placed on one side of the fixed housing 11, with the eyepiece 8 and objective lens 9 of the telescope body 1 corresponding to the eyepiece cover 2 and objective lens cover 3, respectively. Then, by rotating the operating knob 20, the operating knob 20 drives the worm gear 19 to rotate. The rotation of the worm gear 19 drives the turbine 18 to rotate, which in turn drives the rotating shaft 17 to rotate. The rotation of the rotating shaft 17 drives the gear 16 to rotate, which in turn drives the two gear plates 15 to move towards each other. The movement of the two gear plates 15 towards each other drives the two connecting blocks 13 to move towards each other, thereby causing the two connecting blocks 13 to move towards the fixed housing 11. The movement of the fixed shell 11 can move the eyepiece cover 2 and the objective lens cover 3 toward the eyepiece 8 and the objective lens 9, so that the eyepiece cover 2 and the objective lens cover 3 are respectively fitted around the eyepiece 8 and the objective lens 9, thereby protecting the eyepiece 8 and the objective lens 9. The self-locking characteristics of the turbine 18 and the worm gear 19 can keep the eyepiece cover 2 and the objective lens cover 3 stable. Then, by putting the hanging rope 5 connected to the fixed shell 11 around the neck, the telescope body can be hung in front of the chest. When in use, by reversing the above steps, the telescope body 1 can be separated from the eyepiece cover 2 and the objective lens cover 3 for use. This allows the protective mechanism 4 to protect the telescope body 1 while also making it convenient for the user to store and carry the telescope body 1.
