Description

Technical Field

[0001] This utility model relates to an optical magnification device, and more particularly to a high-resolution telescope with a quick-assembly and disassembly lens assembly. Background Technology

[0002] The forced anti-myopia reading zoom lens disclosed in Chinese Utility Model Patent Publication No. CN218099783U includes an adjustment mechanism standing upright on the ground, an eyepiece mounted on the top side of the adjustment mechanism and located above the desk, and an objective lens spaced opposite to the eyepiece. The adjustment mechanism has a support arm, a mounting bracket pivotally connected to the upper end of the support arm for mounting the eyepiece, and two connecting shafts pivotally mounted at opposite ends of the mounting bracket for mounting the objective lens. The objective lens and the eyepiece are rotatably connected to each other via the connecting shafts. When a user places a book on the desk, the contents of the book are reflected into the user's eyes through the optical reflection principle of the objective lens and the eyepiece.

[0003] While using the aforementioned telephoto lens to read allows for a greater reading distance and ensures a proper reading posture, the lack of a quick-release mechanism for the eyepiece and objective lens makes them difficult to separate from the adjustment mechanism. Furthermore, the weight of the adjustment mechanism makes the eyepiece and objective lens prone to breakage during packaging and transportation. Additionally, the telephoto lens can only be used on the ground, limiting its applicability. Utility Model Content

[0004] The purpose of this invention is to provide a high-angle telescope with quick-assembly and disassembly lens assemblies that is easy to package and transport.

[0005] This utility model discloses a high-resolution telephoto lens with a quick-release lens assembly, suitable for reflecting magnified images of objects to the user's eyes. The high-resolution telephoto lens with a quick-release lens assembly includes a support unit and a lens assembly unit.

[0006] The support unit includes an arm assembly and a movable seat disposed at one end of the arm assembly. The movable seat has two extension arms spaced apart in a left-right direction, each extension arm having a joint. The lens assembly unit is detachably disposed on the movable seat and includes a mounting base, an objective lens assembly, and an eyepiece assembly.

The objective lens assembly is disposed on the mounting arm and has an objective lens for facing the object. The eyepiece assembly is disposed on the fixed arm and is spaced apart from the objective lens assembly in a front-back direction. The eyepiece assembly has an eyepiece for viewing by the user.

[0007] The present invention provides a high-resolution telescope with quick-assembly and disassembly lens assemblies. Each of the extension arms has an arm body and a first magnetic chuck fixed to the arm body. Each first magnetic chuck is used to magnetically attract the corresponding mounting arm.

[0008] The present invention provides a high-resolution telescope with quick-assembly and disassembly lens assemblies, wherein each of the mounting arms has a second magnetic member for magnetically attaching to the corresponding first magnetic member.

[0009] The high-angle telescope of this invention has a quick-assembly and disassembly lens assembly, wherein the joint of each of the extension arms is a groove.

[0010] The present invention relates to a high-resolution telescope with a quick-assembly and disassembly lens assembly. The movable base includes a base body and a universal joint. The extension arm is formed on the base body. The universal joint rotatably connects the base body and the arm assembly and is used to drive the base body to rotate relative to the arm assembly about a horizontal axis, which extends along the front-back direction.

[0011] The present invention provides a high-exposure telescope with a quick-assembly and disassembly lens assembly. The universal joint has a first joint connecting the arm assembly and a second joint connecting the first joint and the base body. The second joint is rotatable relative to the first joint about the horizontal axis.

[0012] The present invention provides a high-exposure telescope with a quick-assembly and disassembly lens assembly. The base body also has a support arm that connects to the extension arm. The support arm has a crossbeam extending in the left-right direction and two pivot pieces extending from the crossbeam in the up-down direction. The pivot pieces are pivotally connected to the universal joint.

[0013] This utility model discloses a high-exposure telescope with a quick-assembly and disassembly lens assembly. The objective lens assembly can rotate relative to the mounting base about a rotation axis. The base body is pivotally connected to the second joint via a shaft. The second joint can rotate relative to the first joint between a first position and a second position about a horizontal axis. In the first position, the shaft is higher than the rotation axis in the vertical direction. In the second position, the shaft is lower than the rotation axis in the vertical direction.

[0014] The present invention relates to a high-angle telescope with a quick-release lens assembly. The eyepiece assembly includes a second lens mount for mounting the eyepiece, and the second lens mount has a locking portion that can be detachably engaged with the fixed arm.

[0015] The present invention provides a high-resolution telescope with a quick-assembly and disassembly lens assembly. The lens assembly unit further includes two shaft assemblies for connecting the mounting base and the objective lens assembly. The shaft assemblies are used to allow the objective lens assembly to be detached from the mounting base and to allow the objective lens assembly to rotate relative to the mounting base.

[0016] The beneficial effects of this utility model are as follows: the mounting arm of the mounting base can be detachably mounted at the joint of the extension arm, and the lens assembly unit can be quickly removed from the movable base, thus having the function of quick-release lens assembly. Therefore, the lens assembly unit and the support unit can be packaged separately to avoid damage to the objective lens and eyepiece of the lens assembly unit, which has the effect of convenient packaging and transportation. At the same time, it also has the advantage of being able to be replaced with another support, and is applicable to a wide range of scenarios. Attached Figure Description

[0029] Before this utility model is described in detail, it should be noted that in the following description, the terms "up," "down," "left," "right," "front," and "back" are not absolute positions and can be interchanged in appropriate circumstances.

[0030] See Figures 1 to 3 This utility model discloses an embodiment of a high-resolution telephoto lens with a quick-release lens assembly, suitable for reflecting a magnified image of an object 91 to the eye of a user 92. The high-resolution telephoto lens with the quick-release lens assembly includes a support unit 100 and a lens assembly unit 300. The object 91 may be, for example, a laptop, mobile phone, tablet, book, document, workpiece, or other items requiring magnified viewing.

[0031] The support unit 100 includes a base 11, multiple suction cups 12, an arm assembly 13, and a movable seat 2. The suction cups 12 are mounted along a vertical direction Z on the bottom side of the base 11 and are used to adhere to a surface (not shown). The surface may be a tabletop or the ground. In this embodiment, the arm assembly 13 is a multi-jointed movable arm, but it can also be a single-arm support or a fixed support.

[0032] See Figures 3 to 5 The movable seat 2 is disposed at the top of the arm assembly 13 and located behind the base 11 in a front-rear direction Y. The movable seat 2 has a universal joint 21 rotatably connected to the arm assembly 13 and a seat body 22 rotatably pivotally mounted on the universal joint 21.

[0033] The seat body 22 has a support arm 221 extending in the left-right direction X and connected to the universal joint 21, and two extension arms 222 spaced apart in the left-right direction X and extending rearward from the support arm 221. The left-right direction X, the front-back direction Y, and the up-down direction Z are substantially perpendicular to each other.

[0034] See Figures 4 to 6The support arm 221 has a crossbeam portion 225 extending in the left-right direction X, and two pivot pieces 226 extending from the crossbeam portion 225 in the up-down direction Z, that is, the pivot pieces 226 are eccentrically arranged. A shaft 227 passes through the pivot pieces 226. Each extension arm 222 has an arm body 223 integrally connected to the support arm 221, and a first magnetic suction member 224 fixed to the outer surface of the arm body 223. Each arm body 223 has a joint portion 220. In this embodiment, each joint portion 220 is a U-shaped groove.

[0035] See Figures 5 to 7 The universal joint 21 is rotatably mounted on the shaft 227 and pivotally connected to the pivot plate 226 and rotatably connected to the arm assembly 13. In this embodiment, the universal joint 21 has a first joint 211 connecting to the arm assembly 13 and a second joint 212 connected to the first joint 211 and pivotally connected to the pivot plate 226 of the base body 22. The first joint 211 is rotatable relative to the arm assembly 13 about a vertical axis L, which extends approximately along the vertical direction Z. The second joint 212 is rotatable relative to the first joint 211 about a horizontal axis C, which is perpendicular to the vertical axis L and extends approximately along the front-rear direction Y. The universal joint 21 drives the base body 22 to rotate relative to the arm assembly 13 about the horizontal axis C and / or the vertical axis L, and the base body 22 can pivot relative to the universal joint 21 about the shaft 227, thereby changing the angle and position of the lens assembly unit 300 in three-dimensional space. In some variations, the universal joint 21 may be replaced with other types of joints, such as, but not limited to, ball joints.

[0036] See Figure 4 , Figure 6 and Figure 8 The lens assembly unit 300 is detachably mounted on the movable base 2 and includes a mounting base 4, an objective lens assembly 5, and an eyepiece assembly 7.

[0037] The mounting base 4 is detachably mounted on the movable base 2 of the support unit 100, and includes two mounting arms 41 spaced apart from the extension arm 222 in the left-right direction X, a fixed arm 42 extending along the left-right direction X and connected to the mounting arms 41, and a connecting arm 43 opposite to the fixed arm 42 in the front-back direction Y and connected to the mounting arms 41. Each mounting arm 41 has an arm portion 411 for sliding into a corresponding engagement portion 220, and a second magnetic member 412 fixed to the inner side of the arm portion 411 for magnetically attracting a corresponding first magnetic member 224. The connecting arm 43 is generally U-shaped and connected to the mounting arm 41. The connecting arm 43 allows the user 92's forehead to approach or rest against it to define a suitable eye distance. Specifically, the arm portion 411 of the mounting arm 41, the fixed arm 42, and the connecting arm 43 are integrally formed. In some variations, either the mounting arm 41 or the extension arm 222 is made of a magnetic material, which eliminates the need for either the first magnetic chuck 224 or the second magnetic chuck 412.

[0038] By sliding the mounting arm 41 into the engagement portion 220 of the extension arm 222, and by magnetically attracting the second magnetic member 412 and the first magnetic member 224, the mounting arm 41 can be detachably engaged with and magnetically attracted to the extension arm 222. This allows the lens assembly unit 300 to be quickly installed on or removed from the support unit 100, providing a quick-release lens assembly. Therefore, the lens assembly unit 300 can be packaged separately from the support unit 100 to prevent damage and facilitate packaging and transportation. In some embodiments, for example, the engagement portion 220 of the mounting arm 41 or the extension arm 222 can be designed with a slightly tight-fitting taper, allowing them to be pressed together, thus achieving the quick-release lens assembly function without the need for magnetic attraction.

[0039] Furthermore, the design of the lens assembly unit 300 being detachable from the support unit 100 also has the advantage of being able to be replaced with another support (not shown), allowing the user 92 to change the support for different occasions, such as changing from a desktop support to a floor support.

[0040] See Figures 8 to 10 The objective lens group 5 is disposed on the mounting arm 41 and has a first lens mount 51, and a lens fixed to the first lens mount 51 for facing the object 91 (see Figure 2 The objective lens 52. The first lens mount 51 has a housing portion 511 for fixing the objective lens 52, and two pivot portions 512 spaced apart from the housing portion 511 in the left-right direction X.

[0041] In some embodiments, the lens assembly unit 300 further includes two shaft assemblies 6. The shaft assemblies 6 connect the mounting base 4 and the objective lens assembly 5. The shaft assemblies 6 respectively connect the pivot 512 and the mounting arm 41. Each shaft assembly 6 includes a connecting member 61 fixed to the corresponding pivot 512 and a mounting groove 413 located on the corresponding mounting arm 41 for the connecting member 61 to slide into. The shaft assembly 6 contains a rotating shaft (not shown) to allow the objective lens assembly 5 to be detached from the mounting base 4 and to rotate relative to the mounting base 4 about a rotation axis R passing through the pivot 512. Therefore, rotating the objective lens assembly 5 changes its angle relative to the object 91, and it has the advantage of stopping as it rotates. Since the objective lens assembly 5 can be detached from the mounting base 4, it can be replaced with another objective lens assembly 5 of different size or curvature to suit different usage scenarios, offering excellent applicability. In some embodiments, each of the coupling members 61 is a magnet and is magnetic, and the stability of the coupling can be improved by magnetically connecting each of the coupling members 61 to the corresponding mounting arm 41.

[0042] The eyepiece assembly 7 is disposed on the fixing arm 42 and spaced apart from the objective lens assembly 5 in the front-rear direction Y. The eyepiece assembly 7 has a second lens mount 71 that can be fixed to the fixing arm 42, and an eyepiece 72 fixed to the second lens mount 71 for viewing by the user 92. In some embodiments, the second lens mount 71 has a locking part 711 that is detachably engaged with the fixing arm 42 to facilitate removal and replacement with another eyepiece assembly 7 of a different size or curvature. In this embodiment, the locking part 711 is two spaced-apart hooks. It is understood that the eyepiece assembly 7 can also be directly fixed to the fixing arm 42.

[0043] When viewing the contents of the object 91 using this embodiment, first pull the arm assembly 13 and adjust the lens unit 300 to a suitable position and height, then move or rotate the lens unit 300 to a suitable angle. Next, the user 92's head approaches the mounting base 4, and their line of sight is aligned with the eyepiece 72. Through the optical reflection of the objective lens 52 and the eyepiece 72, the user 92 can see a magnified virtual image of the object 91 at a distance in the eyepiece 72, which is the magnified image of the object 91. This invention increases the imaging distance of the object 91 and magnifies the image, thereby increasing the viewing distance and relaxing the lens of the eye, preventing excessive strain and fatigue on the user 92's eye.

[0044] See Figure 5 , Figure 7 and Figure 11It should be further noted that the second joint 212 of the universal joint 21 can be in a first position relative to the first joint 211 with the horizontal axis C as the center (see... Figure 7 ), and a second position (see Figure 11 The movable seat 2 can rotate between the two sides, allowing it to flip up and down.

[0045] like Figure 7 As shown, when the second joint 212 is in the first position, the shaft 227 is higher than the rotation axis R in the vertical direction Z.

[0046] like Figure 11 As shown, when the second joint 212 is in the second position, the shaft 227 is lower than the rotation axis R in the vertical direction Z.

[0047] For example, such as Figure 12 As shown, when attending class, in addition to reading the object 91 (i.e., the book) placed on the table, it is also necessary to look at the blackboard at the front of the classroom through the gap between the connecting arm 43 and the eyepiece assembly 7. However, because the second joint 212 is in the first position (e.g., Figure 12 When the top of the support unit 100 is in the above figure, it will obstruct the view. Therefore, before class, the user 92 rotates the second joint 212 to the second position (as shown in the figure above). Figure 12 (See the figure below) By flipping the movable seat 2 up and down, the shaft 227 is lower than the rotation axis R in the vertical direction Z. In other words, the top of the support unit 100 is lower than the user's line of sight, which can prevent the top of the support unit 100 from blocking the line of sight. It has the function of seeing both near (reading mode) and far (class mode) at the same time. Therefore, this embodiment is highly practical.

[0048] like Figure 10 As shown, it should be noted that in order to keep the orientation of the objective lens group 5 and the eyepiece group 7 unchanged, the lens group unit 300 will be detached from the movable base 2 before the movable base 2 is flipped. After the movable base 2 is flipped, the lens group unit 300 can be put back into the movable base 2.

[0049] In summary, by means of the mounting arm 41 of the mounting base 4 being detachably mounted at the joint 220 of the extension arm 222, the lens assembly unit 300 can be removed from the movable base 2, and the lens assembly unit 300 and the support unit 100 can be packaged separately. This avoids damage to the objective lens 52 and the eyepiece 72, facilitating packaging and transportation. It also allows for easy transfer to another support, making it suitable for a wide range of applications. Therefore, this invention effectively achieves its intended purpose.

[0050] The above description is merely an embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Any simple equivalent changes and modifications made in accordance with the claims and description of the present utility model shall still fall within the scope of the present utility model.
