Description

Technical Field

[0001] The utility model provides a replaceable front shell of a handheld telescope, and relates to the technical field of telescopes. Background Art

[0002] A telescope is an optical instrument that uses lenses, reflectors and other optical devices to observe distant objects. It can be divided into two types: handheld and desktop. Handheld telescopes can be connected to cameras and mobile phones when in use, making it convenient to take pictures behind the telescope.

[0003] The patent with the patent authorization announcement number CN217112882U discloses a single-hinge central axis focusing waterproof binoculars. The patent proposes to protect the operator's eyes by setting silicone pads and bumps to avoid prolonged use of the skin around the eyes and contact with the shell, which causes the eyes to be squeezed and uncomfortable, and effectively relieve eye fatigue. However, the binoculars provided by the patent still have shortcomings in actual use. The eyepiece of the binoculars can only be fine-tuned when focusing, and the shell cannot be removed to replace the eyepiece, so the scope of use is limited.

[0004] Therefore, it is necessary to provide a replaceable front shell of a handheld telescope, through the setting of a threaded barrel, the eyepiece barrel can be disassembled to replace the eyepiece. Utility Model Content

[0006] In order to achieve the above-mentioned purpose, the embodiment of the utility model provides the following technical solution: a replaceable handheld telescope front shell, including a front shell body, on which a plurality of first mounting holes for connecting to a middle shell are opened, and also including a threaded barrel, on which the front shell body is mounted a threaded barrel, and on which an internal thread is arranged.

[0007] In addition, it is particularly preferred that a plurality of fixing holes are provided on the threaded barrel, and the eyepiece barrel connected to the threaded barrel is fixed by rotating the adjusting screws in the fixing holes.

[0008] In addition, it is particularly preferred that a prism tube is further included, the prism tube is mounted on the front shell body, a prism insertion hole is opened on the prism tube, and the prism rotates in the prism insertion hole.

[0009] Furthermore, it is particularly preferred that the inner walls of the prism tube and the threaded tube are sprayed with metallic paint.

[0010] In addition, it is particularly preferred that it further includes a plug-in hole opened on the front shell body, and two second mounting holes are opened at the rear of the plug-in hole.

[0011] Furthermore, it is particularly preferred that a protective cover is provided on the prism tube.

[0012] Furthermore, it is particularly preferred that a sealing ring is embedded in the threaded barrel.

[0013] In addition, it is particularly preferred that a protective cover is installed on the front shell body.

[0014] Compared with the prior art, the telescope front shell provided by the embodiment of the utility model has the following advantages: 1. The eyepiece barrel is rotated along the thread of the threaded barrel for disassembly and assembly, and the adjusting screw on the fixing hole is rotated so that the adjusting screw clamps the eyepiece barrel in the threaded barrel, thereby achieving the effect of convenient replacement.

[0015] 2. By rotating the prism in the prism socket on the inner wall of the prism tube, the imaging can be adjusted and made upright, giving the user a better experience. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0022] Embodiment 1: A replaceable front shell of a handheld telescope, see Figure 1-Figure 3 As shown, it includes a front shell body 1, which is provided with three first mounting holes 4 for connecting to the middle shell, and also includes a threaded barrel 2. The lower part of the front shell body 1 is installed with the threaded barrel 2 by welding, and the threaded barrel 2 is provided with an internal thread. The threaded barrel 2 is circumferentially provided with three fixing holes 3, and the fixing holes 3 are provided with adjusting screws in the internal threads. The eyepiece barrel connected to the threaded barrel 2 is fixed by rotating the adjusting screws in the fixing holes 3.

[0023] When using the telescope, if the eyepiece magnification is not enough or the eyepiece is scratched and damaged, the eyepiece barrel can be disassembled and assembled by rotating it along the thread of the threaded barrel 2 to replace the eyepiece. After replacing the eyepiece, the adjusting screw on the fixing hole 3 can be rotated to move the adjusting screw radially along the fixing hole 3 toward the center of the threaded barrel 2, so that the adjusting screw clamps the eyepiece barrel in the threaded barrel 2, making it difficult for the eyepiece barrel to loosen and detach from the threaded barrel 2.

[0024] Example 2: Based on Example 1, refer to Figure 2 and Figure 3 As shown, it also includes a prism barrel 5. The prism barrel 5 is installed on the upper part of the front shell body 1 by welding. A prism socket 7 is opened on the inner wall of the prism barrel 5. The prism rotates in the prism socket 7. The inner walls of the prism barrel 5 and the threaded barrel 2 are sprayed with metallic paint to prevent rust inside the prism barrel 5 and the threaded barrel 2.

[0025] When using the telescope, the prism can be rotated in the prism insertion hole 7 on the inner wall of the prism tube 5 to adjust the image so that the image is upright, which provides the user with a better experience.

[0026] See also Figure 4 As shown, it also includes a data interface 8 opened on the front shell body 1, the data interface 8 is used to connect other devices and transmit observation data, and two second mounting holes 6 for installing metal connectors are opened at the rear of the data interface 8. A protective cover 9 is sleeved on the prism tube 5; a sealing ring 10 is embedded in the threaded tube 2; and a protective cover 11 is installed on the outer edge of the front shell body 1 by gluing.

[0027] When the telescope is not in use, the protective cover 9 is put on the prism tube 5 to protect the prism. The setting of the sealing ring 10 makes the connection between the eyepiece tube and the threaded tube 2 tighter, preventing water from penetrating into the telescope body through the gap between the eyepiece tube and the threaded tube 2, thereby improving the use environment. The protective cover 11 is used to cushion the impact on the front shell body 1 to prevent the front shell body 1 from being broken or damaged when it falls or is hit.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
