Description

Technical Field

[0001] This utility model relates to the field of telescope technology, and in particular to a portable telescope. Background Technology

[0002] A telescope is an optical instrument that uses lenses, mirrors, and other optical components to observe distant objects. It works by refracting light through a lens or reflecting it with a concave mirror, causing it to converge into an image through a small aperture. This image is then magnified by an eyepiece and seen through the lens; it is also known as a "telescope." Telescopes are now extremely common instruments. However, existing telescopes are easily damaged by drops or impacts during transport, causing unnecessary economic losses and shortening their lifespan. Some telescopes now have dedicated protective structures, such as the portable binoculars described in CN202223610828.8, which use a protective ring 3 to protect the objective lens 2. During use, the protective ring 3 is screwed into the telescope or out of the objective lens 2 for protection. However, this structure is only suitable for telescopes with small objective lenses. For telescopes with larger objective tubes, if such a protective ring 3 is to be used, the telescope body would need to be larger, resulting in an oversized telescope that reduces its ease of use and portability; its practicality is poor. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a portable telescope to solve the problems in the background art.

[0004] To achieve the above objectives, the present invention mainly adopts the following technical solution:

[0008] Furthermore, the inner surface of the protective shell is provided with a raised strip, and the outer surface of the main body is provided with a corresponding groove, the raised strip being embedded in the groove.

[0009] Furthermore, a vertical limiting surface is provided on the outer surface of the main body, and the inner end face of the protective shell is arranged opposite to the limiting surface.

[0010] Furthermore, the protective cover includes a main body and a buffer sleeve disposed on the outside of the main body. The main body is made of plastic material, and the buffer sleeve is made of soft rubber material.

[0011] Furthermore, the buffer sleeve includes an inner side portion and an outer edge portion, the inner side portion being attached to the inner surface of the main body portion, and the outer edge portion being folded outward and sleeved on the outer surface of the main body portion.

[0012] Furthermore, a limiting groove is provided at the lower end of the inner surface of the main body, and a protruding ring is provided on the bottom inner surface of the inner side, the protruding ring being embedded in the limiting groove.

[0013] Furthermore, a protrusion is provided on the outer side of the top end of the main body, and the outer edge is fitted onto the main body below the protrusion.

[0014] Furthermore, the mounting plate is disposed inside the connecting part, and a rack extending in the front-rear direction is provided on the mounting plate, and the transmission gear of the adjusting member meshes with the rack; the rotating handle extends outside the connecting part, and an extension hole is provided at the bottom of the front end of the connecting part; the mounting plate is movably installed inside the connecting part and extends outside the connecting part; the front end of the moving plate extends to the outer side and is connected to the rear end of the protective shell.

[0015] In summary, this invention improves the safety and lifespan of the telescope by providing a retractable protective shell for the objective lens assembly and a protective cover for the eyepiece assembly, reducing the likelihood of collision damage or breakage, and enhancing the convenience of carrying and using it outdoors. Furthermore, the protective cover not only improves contact comfort but also ensures a closer fit to the eye socket, preventing large gaps in light transmission.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 5 As shown, this utility model provides a portable telescope, which includes two telescope tubes 10, a connecting part 20, two protective covers 30, two end caps 40, a protective shell 50, and a connecting strap 60. The connecting part 20 is connected to the two telescope tubes 10. The two protective covers 30 are installed on the rear ends of the two telescope tubes 10. The end caps 40 cover the front ends of the two telescope tubes 10. The protective shell 50 is disposed on the outer side of the front end of the telescope tubes 10. The connecting strap 60 is installed on the side of the two telescope tubes 10 for easy carrying by hand, hanging around the neck, or on the shoulder.

[0025] The microscope tube 10 includes a main body 11, an eyepiece assembly 12, and an objective lens assembly 13. The eyepiece assembly 12 is located at the rear end of the main body 11, and the objective lens assembly 13 is located at the front end of the main body 11. Lenses are provided on both the eyepiece assembly 12 and the objective lens assembly 13. An end cap 40 covers the front end face of the objective lens assembly 13, and a protective cover 30 is mounted on the eyepiece assembly 12. A protective shell 50 is mounted on the main body 11 and can move along the main body 11 to the outside of the objective lens assembly 13 to house the objective lens assembly 13 within the protective shell 50, thus providing a certain degree of protection for the objective lens assembly 13 and improving its service life. In this embodiment, the objective lens assembly 13 is arranged with a larger outer side and a smaller inner side, and its outer side has multiple spiral adjustment ring structures. Collisions or drops can easily damage the objective lens assembly 13 or prevent the spiral adjustment rings from rotating properly.

[0026] A mounting plate 21 is provided at the center of the bottom surface of the connecting part 20. The mounting plate 21 has an adjusting hole 22 extending in the front-rear direction, and adjusting teeth are provided on both opposite sides of the adjusting hole 22. The protective shell 50 is mounted on the mounting plate 21 via an adjusting component 70. The adjusting component 70 includes an adjusting handle 71, a transmission gear 72, and a connecting shaft (not shown). The connecting shaft connects to the transmission gear 72 and the adjusting handle 71. The transmission gear 72 meshes with the adjusting teeth on both sides of the adjusting hole 22. The connecting shaft passes through the protective shell 50, and the adjusting handle 71 is located on the outer surface of the protective shell 50. In use, by rotating the adjusting handle 71, the transmission gear 72 can move along the adjusting teeth of the adjusting hole 22, and the protective shell 50 will move back and forth accordingly. Furthermore, a protruding strip 51 is provided on the inner surface of the protective shell 50, and a corresponding groove (not shown) is provided on the outer surface of the main body 11, with the protruding strip 51 embedded in the groove. A limiting surface 111 is also provided on the outer surface of the main body 11. The limiting surface 111 is used to limit the protective shell 50 and make the appearance more aesthetically pleasing.

[0027] An infrared lamp 21 is provided at the front end of the connecting part 20, and a dial 22 is provided at the rear end. The protective cover 30 is mounted on the eyepiece assembly 12 and extends to the outer end. In this embodiment, the protective cover 30 is flared, with two protective covers 30 respectively located on the left and right sides of the infrared lamp 21, and the maximum vertical dimension of the protective cover 30 also extends beyond the outer side of the infrared lamp 21. Thus, the protective cover 30 can not only protect the eyepiece assembly 12, but also provide a certain degree of protection for the infrared lamp 21.

[0028] The protective cover 30 includes a main body 31 and a buffer sleeve 32 disposed on the outside of the main body 31. The main body 31 has the same shape as the protective cover 30 and is a thin sheet. Furthermore, the main body 31 is made of injection-molded plastic. The buffer sleeve 32 is made of soft rubber and includes an inner side 321 and an outer edge 322. The shape of the inner side 321 is consistent with the inner surface shape of the main body 31 and it fits against the inner surface of the main body 31. More specifically, a limiting groove 311 is provided at the lower end of the inner surface of the main body 31, and a protruding ring 3211 is provided on the bottom inner surface of the inner side 321. The protruding ring 3211 is embedded in the limiting groove 311, thereby making the installation of the buffer sleeve 32 more secure.

[0029] The outer edge 322 is folded outward and fitted onto the outer surface of the main body 31. A protrusion 312 is provided on the outer side of the top of the main body 31. The outer edge 322 is fitted onto the main body 31 below the protrusion 312. The protrusion 312 can provide a certain limiting effect on the outer edge 322, thereby further improving the stability of the cushioning sleeve installation. In this embodiment, the cushioning sleeve 32 is made of silicone. Furthermore, the cushioning sleeve 32 is made of soft silicone, which not only improves comfort when in contact with the eye area but also provides a better fit. In addition, the cushioning sleeve 32 can be replaced with thicker or thinner materials as needed to suit the needs of different users. New cushioning sleeves 32 can also be replaced depending on the user, improving hygiene.

[0030] The end cap 40 is integrally connected to the objective lens assembly 12 via a connecting strap 41. A magnetic clasp (not shown) is provided on the bottom front surface of the objective lens assembly 12, and a metal sheet is provided on the outer surface of the end cap 40. In use, the end cap 40 is opened and folded back so that the metal sheet on the outer surface is attracted to the magnetic clasp, thereby not only preventing the lens cap from being lost, but also preventing the lens cap from shaking and affecting the observation experience.

[0031] like Figure 6 As shown, this is a second embodiment of the driving device for the protective shell 50 of this utility model. A movable plate 21a is provided on the inner bottom side of the connecting part 20. A rack 22a extending in the front-rear direction is provided on the movable plate 21a. The adjusting member 70a has a basically the same structure, also including a rotating handle 71a, a transmission gear 72a, and a connecting shaft 73a. The transmission gear 72a meshes with the rack 22a. The rotating handle 71a extends outside the connecting part 20. An extension hole (not shown) is provided at the bottom of the front end of the connecting part 20. The movable plate 21a is movably installed inside the connecting part 20 (guide grooves are provided on both sides of the movable plate 21a inside the connecting part 20, and the movable plate 21a can move back and forth along the guide grooves). The movable plate 21a extends out of the connecting part 20a through the extension hole, and the front end of the movable plate 21a extending outwards is connected to the rear end of the protective shell 50. In use, rotating the rotating handle 71a causes the transmission gear 72a to push the moving plate 21a to move back and forth, thereby covering the protective housing 50 with the objective lens assembly 13 or exposing the objective lens assembly 13.

[0032] In summary, this utility model improves the safety and lifespan of the telescope by providing a retractable protective shell 50 to protect the objective lens assembly 13 and a protective cover 30 to protect the eyepiece assembly 12. It also reduces the likelihood of collision damage or breakage and enhances the convenience of carrying and using the telescope outdoors. Furthermore, the protective cover 30 not only improves contact comfort but also ensures a closer fit to the eye socket, preventing large light-transmitting gaps. This utility model is highly practical and has significant potential for widespread application.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
