Description

Technical Field

[0001] This utility model relates to an optical magnification device, and in particular to a suction cup type high-speed zoom lens. 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] Although using the aforementioned telephoto lens to read can increase the reading distance and ensure a proper reading posture, the single-point support design of the telephoto lens, which uses a circular base, makes it prone to tipping over and less stable. Utility Model Content

[0021] See Figures 1 to 3 This utility model's suction cup type high-resolution zoom lens is suitable for optically magnifying the image of an object (not shown), such as, but not limited to, mobile phones, tablets, and books. The suction cup type high-resolution zoom lens includes a support unit 100 and a lens assembly unit 300.

[0022] The support unit 100 includes a base 11, at least three suction cups 12, an arm assembly 13, and a movable seat 2. The base 11 has three radially arranged support feet 111. The suction cups 12 are respectively fixed to the support feet 111. The suction cups 12 utilize the principle of three points forming a plane, which makes them relatively stable. In some variations, the number of suction cups 12 may be four or more.

[0023] See Figure 2 , Figure 4 and Figure 5 The suction cups 12 are offset from each other at an angle in a circumferential direction and are disposed on the bottom side of the support foot 111 along a vertical direction Z. The arm assembly 13 is disposed on the top side of the base 11 along the vertical direction Z. In this embodiment, the arm assembly 13 is a multi-segment cantilever with multiple movable arms 131, which can move or rotate in three-dimensional space. The movable seat 2 is rotatably positioned at the top of the arm assembly 13 and is driven by the arm assembly 13 to change its height and position. In some embodiments, the movable seat 2 has a universal joint 21 connected to the arm assembly 13 and a seat body 22 to which the universal joint 21 is rotatably connected.

[0024] In some embodiments, each suction cup 12 has a plate body 121 and an operating member 122 operably disposed on the plate body 121. Specifically, the operating member 122 is a pull handle and pivotally mounted on the plate body 121. When the operating member 122 is pressed down, a vacuum state is created between the plate body 121 and a tabletop 9, resulting in strong suction force, thus the support unit 100 can be stably fixed to the tabletop 9. When the operating member 122 is opened, the suction cup 12 can achieve equilibrium with external pressure, and can be easily detached from the tabletop 9.

[0025] In some embodiments, each suction cup 12 further has an adhesive 123 applied to the bottom surface of the plate body 121. The adhesive 123 can be squeezed and fill the gap between the plate body 121 and the tabletop 9 to increase the suction force of the suction cup 12 and further improve the stability of the support unit 100. The adhesive 123 is an existing material and will not be described in detail here.

[0026] See Figure 1 , Figure 2 and Figure 6 The lens assembly unit 300 is disposed on the movable base 2 and supported by the arm assembly 13. The lens assembly unit 300 includes a mounting base 4, an objective lens group 5, and an eyepiece group 7.

[0027] The mounting base 4 is disposed on the movable base 2 of the support unit 100.

[0028] The objective lens assembly 5 is disposed on the rear side of the mounting base 4 along a front-rear direction Y, and has a first lens mount 51 disposed on the mounting base 4, and an objective lens 52 fixed to the first lens mount 51. In this embodiment, the objective lens 52 is a convex mirror with free curvature. In some embodiments, the objective lens assembly 5 is rotatably pivotally mounted on the mounting base 4 to facilitate changing the angle of the objective lens 52.

[0029] The eyepiece group 7 and the objective lens group 5 are spaced apart in the front-rear direction Y and are disposed on the front side of the mounting base 4 along the front-rear direction Y. The eyepiece group 7 has a second lens mount 71 disposed on the mounting base 4 and an eyepiece 72 fixed to the second lens mount 71. In this embodiment, the eyepiece 72 is a concave mirror with free curvature.

[0030] In some embodiments, the base body 22 of the movable seat 2 is U-shaped, and the mounting base 4 of the lens assembly unit 300 has two mounting arms 41 spaced apart in a left-right direction X and capable of sliding into the base body 22, allowing the mounting base 4 to be detachably mounted on the base body 22. Therefore, the lens assembly unit 300 can be removed from the support unit 100 for convenient packaging and transportation. The left-right direction X, the front-back direction Y, and the up-down direction Z are perpendicular to each other.

[0031] In use, the suction cup 12 is attached to the tabletop 9, and the arm assembly 13 is pulled to adjust the lens unit 300 to a suitable position and height, and the lens unit 300 is moved or rotated to a suitable angle. Then, the user's head is brought close to the mounting base 4, and their line of sight is aligned with the eyepiece 72. The image of the object is first reflected by the objective lens 52 for magnification, and then reflected by the eyepiece 72 before entering the user's eye. Through the optical reflection of the objective lens 52 and the eyepiece 72, the imaging distance of the object can be increased and the image magnified, thereby increasing the viewing distance and avoiding excessive strain on the eyes. Simultaneously, the suction cup 12 is provided on the bottom side of the base 11. The suction force of the suction cup 12 improves the stability of the support unit 100, making the center of gravity more stable and less prone to tipping over, thus ensuring high safety during use. This embodiment also utilizes the adhesive 123 to fill the gap between its respective disc body 121 and the tabletop 9. Even if the tabletop 9 has unevenness, such as pits or undulations, each suction cup 12 can be firmly adhered to the tabletop 9 with strong adhesion. Therefore, the purpose of this utility model is indeed achieved.

[0032] 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.
