Description

Technical Field

[0001] This utility model relates to the field of astronomical telescope technology, and in particular to an astronomical telescope with an easy-to-change eyepiece. Background Technology

[0002] An astronomical telescope is an optical instrument used to observe celestial bodies. It collects and focuses celestial radiation (such as visible light and radio waves) to reveal the mysteries of the universe. Its core consists of an objective lens (or primary mirror) and an eyepiece: the objective lens gathers light from celestial bodies to form a real image, and the eyepiece magnifies it for observation. According to their working principle, they are classified into refractive (using lenses for refraction), reflective (relying on mirrors for reflection), and catadioptric (combining both). Modern telescopes are often equipped with CCD / CMOS detectors, spectrometers, and other equipment that can convert light signals into digital data. Radio telescopes receive radio waves through parabolic antennas. They are widely used for observing celestial bodies such as stars, galaxies, and planets. For example, the Hubble Telescope captures images of deep space, and FAST detects cosmic radio signals. They are key tools for humankind to explore the universe.

[0003] Currently, most astronomical telescopes use threaded assembly for their eyepieces. During assembly and disassembly, the eyepieces need to be screwed on, which can easily cause wear and tear and affect their lifespan. Therefore, an improvement in the assembly process is needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where eyepieces in most astronomical telescopes are assembled via threads, requiring twisting during assembly and disassembly, which easily causes eyepiece wear and affects the lifespan of the eyepieces. The invention proposes an astronomical telescope with an eyepiece that is easy to replace.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an astronomical telescope that facilitates eyepiece replacement, comprising an astronomical telescope body and an eyepiece body, wherein an adapter is installed at one end of the astronomical telescope body and the eyepiece body is located on one side of the adapter.

[0006] The adapter surface is provided with a quick-release structure, which includes a positioning seat fixedly connected to the adapter surface. One end of the eyepiece body is inserted into the positioning seat, and a retaining ring is fixedly connected to the eyepiece body. The outer diameter of the retaining ring is larger than the inner diameter of the positioning seat. A sliding sleeve is slidably connected to the eyepiece body, and a threaded cylinder is rotatably connected to the side of the sliding sleeve near the adapter. The threaded cylinder is threaded onto the positioning seat and pre-positioned by a locking block and a limiting groove. It is initially fixed by adsorption with the first and second magnetic rings. Then, the sliding sleeve and the threaded cylinder are controlled to push, pull, and tighten. Installing the eyepiece only requires three steps. When disassembling, the eyepiece can be pulled out by rotating the threaded cylinder in the opposite direction. No additional tools are required, which is suitable for quickly switching eyepieces with different focal lengths during observation. Compared with the traditional threaded connection method, this solution is more stable. During disassembly and installation, it is not necessary to rotate the eyepiece body, which effectively ensures that the eyepiece body is in a stable state.

[0007] Preferably, a first magnetic ring is mounted on the surface of the adapter, and a second magnetic ring is mounted on the side of the eyepiece body near the adapter. The second magnetic ring and the first magnetic ring are magnetically attracted to each other, and the first magnetic ring and the second magnetic ring provide an initial attraction force to effectively position the eyepiece body.

[0008] Preferably, a retaining ring is fixedly connected to a locking block on the side near the adapter. The locking block is fixedly connected to the surface of the eyepiece body. A limiting groove is formed on the inner wall of the positioning seat. One end of the locking block is inserted into the limiting groove. The retaining ring and the locking block effectively limit the depth of the eyepiece body inserted into the positioning seat, avoiding over-installation, reducing the probability of damage to the eyepiece body, and improving the service life of the eyepiece body.

[0009] Preferably, the edges of the card block near the adapter are rounded. The rounded edge design of the card block reduces the frictional resistance during insertion and removal, making the operation smoother.

[0010] Preferably, a sliding rod is fixedly connected to the side of the retaining ring away from the adapter, and a guide hole is provided on the surface of the sliding sleeve. The sliding rod slides against the inner wall of the guide hole, effectively limiting the displacement of the sliding sleeve.

[0011] Preferably, a stop block is fixedly connected to the end of the slide rod away from the slide sleeve, and a tension spring is fixedly connected to the side of the stop block near the retaining ring. The end of the tension spring away from the stop block is fixedly connected to the surface of the slide sleeve. When disassembling the eyepiece, the threaded cylinder is rotated in the opposite direction to unscrew it from the positioning seat. Under the action of the elastic restoring force of the tension spring, the slide sleeve and the threaded cylinder automatically return to their original positions.

[0012] Preferably, the surface of the threaded cylinder is fixedly connected with an anti-slip block, which increases the friction when the threaded cylinder is rotated, making it easier to operate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the eyepiece is pre-positioned by the locking block and the limiting groove, and initially fixed by the adsorption of the first magnetic ring and the second magnetic ring. Then, the sliding sleeve and the threaded cylinder are controlled to push, pull and tighten. The eyepiece can be installed in only three steps. When disassembling, the eyepiece can be pulled out by rotating the threaded cylinder in the opposite direction. No additional tools are required. It is suitable for quickly switching eyepieces with different focal lengths during observation. Compared with the traditional threaded connection method, this solution is more stable. During disassembly and installation, it is not necessary to rotate the eyepiece body, which effectively ensures that the eyepiece body is in a stable state.

[0015] 2. In this utility model, the retaining ring and the locking block effectively limit the depth of the eyepiece body inserted into the positioning seat, avoid over-installation, reduce the probability of damage to the eyepiece body, and improve the service life of the eyepiece body.

[0023] Please see Figures 1-5The present invention provides a technical solution: an astronomical telescope with easy eyepiece replacement, comprising an astronomical telescope body 1 and an eyepiece body 3, wherein an adapter 2 is installed at one end of the astronomical telescope body 1, and the eyepiece body 3 is located on one side of the adapter 2.

[0024] The surface of the adapter 2 is provided with a quick-release structure 4, which includes a positioning seat 49. The positioning seat 49 is fixedly connected to the surface of the adapter 2. One end of the eyepiece body 3 is inserted into the positioning seat 49. A retaining ring 47 is fixedly connected to the eyepiece body 3. The outer diameter of the retaining ring 47 is larger than the inner diameter of the positioning seat 49. A sliding sleeve 45 is slidably connected to the eyepiece body 3. A threaded cylinder 41 is rotatably connected to the side of the sliding sleeve 45 near the adapter 2. The threaded cylinder 41 is threaded onto the positioning seat 49 and is pre-positioned by the locking block 48 and the limiting groove 411. It is initially fixed by adsorption with the first magnetic ring 410 and the second magnetic ring 412. Then, the sliding sleeve 45 and the threaded cylinder 41 are controlled by pushing, pulling and tightening. The eyepiece can be installed in only three steps. When disassembling, the eyepiece can be pulled out by rotating the threaded cylinder 41 in the opposite direction. No additional tools are required. It is suitable for quickly switching eyepieces with different focal lengths during observation. Compared with the traditional threaded connection method, this solution is more stable. During disassembly and installation, it is not necessary to rotate the eyepiece body 3, which effectively ensures that the eyepiece body 3 is in a stable state.

[0025] Specifically, a first magnetic ring 410 is installed on the surface of the adapter, and a second magnetic ring 412 is installed on the side of the eyepiece body 3 near the adapter 2. The second magnetic ring 412 and the first magnetic ring 410 are magnetically attracted to each other. The first magnetic ring 410 and the second magnetic ring 412 provide initial attraction force, which effectively positions the eyepiece body 3.

[0026] In this embodiment: a retaining ring 47 is fixedly connected to a locking block 48 on the side near the adapter 2. The locking block 48 is fixedly connected to the surface of the eyepiece body 3. A limiting groove 411 is formed on the inner wall of the positioning seat 49. One end of the locking block 48 is inserted into the limiting groove 411. The retaining ring 47 and the locking block 48 effectively limit the depth of the eyepiece body 3 inserted into the positioning seat 49, avoid over-installation, reduce the probability of damage to the eyepiece body 3, and improve the service life of the eyepiece body 3.

[0027] Specifically, the edges of the card block 48 near the adapter 2 are rounded. The rounded edge design of the card block 48 reduces the frictional resistance when inserting and removing, making the operation smoother.

[0028] Specifically, a slide rod 43 is fixedly connected to the side of the retaining ring 47 away from the adapter 2, and a guide hole 413 is opened on the surface of the slide sleeve 45. The slide rod 43 slides against the inner wall of the guide hole 413, effectively limiting the displacement of the slide sleeve 45.

[0029] In this embodiment: a stop 46 is fixedly connected to the end of the slide rod 43 away from the slide sleeve 45, and a tension spring 44 is fixedly connected to the side of the stop 46 near the retaining ring 47. The end of the tension spring 44 away from the stop 46 is fixedly connected to the surface of the slide sleeve 45. When disassembling the eyepiece, the threaded cylinder 41 is rotated in the opposite direction and unscrewed from the positioning seat 49. Under the action of the elastic restoring force of the tension spring 44, the slide sleeve 45 and the threaded cylinder 41 automatically return to their original positions.

[0030] Specifically, the surface of the threaded cylinder 41 is fixedly connected with an anti-slip block 42, which increases the friction when rotating the threaded cylinder 41 and facilitates operation.

[0031] Working principle: When installing the eyepiece, first align one end of the eyepiece body 3 with the positioning seat 49, so that the locking block 48 on the retaining ring 47 is aligned with the limiting groove 411 on the inner wall of the positioning seat 49. Insert the eyepiece body 3 into the positioning seat 49, and the locking block 48 is embedded in the limiting groove 411, forming a preliminary positioning and restricting the circumferential rotation of the eyepiece body 3. At this time, the first magnetic ring 410 on the surface of the adapter 2 and the second magnetic ring 412 on one side of the eyepiece body 3 are magnetically attracted to each other, providing additional pre-tightening force to ensure the stability of the initial state of the eyepiece installation.

[0032] Next, the sliding sleeve 45 is pushed, and it slides along the sliding rod 43. The tension spring 44 is deformed by the force, which drives the threaded cylinder 41, which is rotatably connected to it, to move forward until the threaded cylinder 41 contacts the positioning seat 49. Then, the threaded cylinder 41 is rotated, and it is tightened onto the positioning seat 49 by means of the threaded engagement. During the tightening process of the threaded cylinder 41, the sliding sleeve 45 pushes the retaining ring 47, so that the eyepiece body 3 is tightly connected to the adapter 2, which further enhances the stability of the eyepiece installation. The anti-slip block 42 increases the friction when rotating the threaded cylinder 41, making it easier to operate.

[0033] When disassembling the eyepiece, rotate the threaded cylinder 41 in the opposite direction to unscrew it from the positioning seat 49. Under the elastic restoring force of the tension spring 44, the sliding sleeve 45 and the threaded cylinder 41 automatically return to their original position. Then, pull the eyepiece body 3 outward directly. The locking block 48 disengages from the limiting groove 411. At the same time, the magnetic attraction between the first magnetic ring 410 and the second magnetic ring 412 is released, and the eyepiece body 3 can be easily removed. The rounded corner design of the locking block 48 reduces the frictional resistance during insertion and removal, making the operation smoother.
