[0024] The present invention provides a device with lens flipping and pupil distance adjustment functions. It has the following beneficial effects:

[0025] 1. This device with lens flipping and lens pupil distance adjustment functions fixes the position of the device by setting a lifting mechanism. When adjusting the position of the lens according to the user's pupil distance, the user needs to hold the device, which makes it difficult to ensure that the device is in a horizontal state, resulting in large errors in measurement and adjustment. By setting a lifting mechanism, the traditional handheld bracket is changed to a movable fixed bracket, and an adjustable position suction cup is used to keep the base stable on the desktop to avoid the two lenses from having different heights due to tilting the device. By symmetrically setting two suction cups, the device position is stably fixed to avoid the device position offset during adjustment, thereby solving the above problem.

[0026] 2. This device, which features lens flipping and interpupillary distance adjustment, utilizes an adjustment mechanism to control the position of a movable rod, bringing the contactor into contact with the user's nose bridge. This allows the device to be positioned so that the alignment assembly is symmetrically positioned between the user's eyes, facilitating interpupillary distance adjustment. Furthermore, during interpupillary distance measurement, the contactor remains in contact with the user, centered within the device, preventing incorrect lens placement due to improper user positioning.

[0027] 3. This device, which has lens flipping and pupil distance adjustment functions, tests the user's pupil distance by providing an alignment component. The position of the mounting component is adjusted according to the pupil position to align the lens with the pupil. Magnetic blocks are evenly arranged in the slide groove, and the magnetic blocks are corresponding to the first alignment opening. The magnetic blocks engage and fix the magnetic sheet, thereby fixing the position of the mounting component to prevent the lens from being misaligned with the pupil. Furthermore, by providing a second alignment opening, the lens position can be checked and adjusted after installation. If the lens position is misaligned with the second alignment opening, the position of the slider is checked, and the slider is readjusted and fixed so that the corresponding magnetic block and magnetic sheet are attracted and fixed.

[0028] 4. The device with lens flipping and pupil distance adjustment functions is equipped with mounting components to place the lenses and stacked lenses separately. The rotating shaft is made of rubber material, and there is friction between the rotating shaft and the rotating frame. When the angle of the rotating frame is manually adjusted, the rotating frame can stay at different angles to complete the lens flipping work. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.

[0041] As Figures 1 - 10 shown, the present invention provides a technical solution: including a base 1, a gasket is installed at the bottom of the base 1;

[0042] a lifting mechanism 2, the lifting mechanism 2 is arranged above the base 1, the lifting mechanism 2 includes a first adjusting rod 205, a lifting rod 206 is installed at the top of the first adjusting rod 205, and a vertical plate 207 is installed at the top of the lifting rod 206;

[0043] an adjusting mechanism 3, the adjusting mechanism 3 is arranged outside the vertical plate 207, and the lifting rod 206 drives the vertical plate 207 and the adjusting mechanism 3 to move to different heights to adapt to the target position.

[0044] Before using the device, manually place the device on the desktop and make the device close to the user. Adjust the lifting mechanism 2 to fix the position of the device, and adjust the height of the adjusting mechanism 3. Then use the adjusting mechanism 3 to complete the pupil distance adjustment and flipping work of the lens.

[0045] The lifting mechanism 2 further includes:

[0046] a mounting plate 202, the mounting plate 202 is installed above the base 1 by screws, and a clamping seat 203 is installed at the top of the mounting plate 202;

[0047] a fixed cylinder 204, the fixed cylinder 204 is arranged inside the clamping seat 203, the fixed cylinder 204 is connected to the clamping seat 203 by a pin, and the first adjusting rod 205 is installed inside the fixed cylinder 204;

[0048] Before using the device, manually fix the position of the device, and then manually adjust the length of the first adjusting rod 205 so that the user's eyes are at the same height as the adjusting mechanism 3.

[0049] After measuring the pupil distance, open the lifting rod 206 to the first stroke and manually install the lens.

[0050] After the installation work is completed, open the lifting rod 206 to the second stroke and manually adjust or flip the lens.

[0051] The through slots 201 are opened inside the base 1. There are two through slots 201, which are symmetrically arranged. The through slots 201 are cylindrical in shape.

[0052] The fixing slots 208 are opened inside the base 1. Circular slots 209 are opened inside the fixing slots 208. There are two circular slots 209, which are symmetrically arranged.

[0053] The springs 210 are installed inside the circular slots 209. The top of the springs 210 is connected with a clamping block 211. A pull ring is arranged at the top of the clamping block 211. A connecting plate 212 is installed outside the clamping block 211. A suction cup 213 is installed at the bottom of the connecting plate 212. The clamping block 211 drives the connecting plate 212 and the suction cup 213 to move up and down.

[0054] Before using the device, manually place the device on the desktop so that the device is at a position close to the user at the edge of the table. Then manually press the pull ring. The pull ring, the clamping block 211 and the spring 210 move downward until the clamping block 211 is stuck into the circular slot 209. At the same time, the clamping block 211 drives the connecting plate 212 and the suction cup 213 to move downward. The suction cup 213 gradually contacts the desktop and is suction-fixed on the desktop, thereby fixing the position of the device.

[0055] When the device needs to be disassembled, manually pull the pull ring. The pull ring drives the clamping block 211 to gradually disengage from the circular slot 209. The spring 210 gradually returns to its original state. The suction cup 213 and the connecting plate 212 gradually return to their original positions. The suction cup 213 disengages from the desktop.

[0056] By setting the lifting mechanism 2, the position of the device is fixed. The traditional handheld bracket is changed to a movable fixed bracket. The suction cup 213 with adjustable position is used to make the base 1 stable on the desktop, avoiding the situation that the heights of the two lenses are different due to the inclination of the device. And by symmetrically arranging two suction cups 213, the situation of the device position deviation during the adjustment process is avoided.

[0057] The adjusting mechanism 3 includes:

[0058] The enclosing plate 301 is annular. The enclosing plate 301 is installed outside the vertical plate 207. A channel 305 is opened inside the vertical plate 207. A moving rod 302 is slidably connected inside the enclosing plate 301. The moving rod 302 is made of rubber. A contact 303 is installed outside the moving rod 302. A handle 304 is installed at one end of the moving rod 302 far from the contact 303.

[0059] Adjusting bent rod 306 is installed outside the enclosure panel 301. An alignment assembly 307 is arranged outside the adjusting bent rod 306, and an installation assembly 308 is arranged outside the alignment assembly 307. There are two adjusting bent rods 306, alignment assemblies 307 and installation assemblies 308 respectively.

[0060] Before using the device, by adjusting the first adjusting rod 205, the user's nose bridge is at the same height as the contact 303. Manually pull the handle 304 to adjust the position of the moving rod 302, so that the contact 303 outside the moving rod 302 contacts the position between the user's nose bridge, that is, in the middle of the user's eyes, so that the contact 303 is in the centered position between the user's two eyes.

[0061] Subsequently, adjust the alignment assembly 307 to measure the user's interpupillary distance.

[0062] By setting the adjusting mechanism 3, control the position of the moving rod 302 so that the contact 303 contacts the user's nose bridge, and then adjust the position of the device so that the alignment assembly 307 is symmetrically located in the middle of the user's eyes, which is convenient for the interpupillary distance adjustment work. And during the process of measuring the interpupillary distance, the contact 303 is always in contact with the user to prevent the position from changing due to the user's movement.

[0063] The alignment assembly 307 includes:

[0064] A cross plate 3071 is installed outside the adjusting bent rod 306. A first alignment opening 3072 is formed inside the cross plate 3071. There are multiple first alignment openings 3072 and they are evenly arranged. Magnets 3077 are installed outside the cross plate 3071. There are multiple magnets 3077 and they are evenly arranged;

[0065] An adapter plate 3073 is installed at the bottom of the cross plate 3071. A second alignment opening 3074 is formed inside the adapter plate 3073. There are multiple adapter plates 3073 and second alignment openings 3074 and they are evenly arranged. A groove 3075 is formed inside the adapter plate 3073. The first alignment opening 3072, the adapter plate 3073 and the second alignment opening 3074 are aligned in the vertical direction;

[0066] A chute 3076 is formed inside the cross plate 3071. A sliding block 3078 is slidably connected inside the chute 3076. The sliding block 3078 is connected to the installation assembly 308.

[0067] Before using the device, the lifting rod 206 is in the initial state. As the contact 303 contacts the middle position of the user's eyes, the tester is on the other side of the device and observes the user's pupil position through the first alignment opening 3072. Then, the sliding block 3078 is manually moved to the magnetic block 3077 corresponding to the first alignment opening 3072, thereby completing the pupil distance adjustment and the adjustment of the mounting assembly 308.

[0068] Manually install the lens in the mounting assembly 308. Then, activate the lift rod 206 to the first stroke, moving the device upward. Align the lens with the second alignment opening 3074 to check if the pupil distance is correct. Then, activate the lift rod 206 to the second stroke, moving the device upward. Adjust the mounting assembly 308 to position the lens in its original position. The lenses can then be stacked or flipped.

[0069] By setting the alignment component 307, the user's pupil distance is tested. The position of the installation component 308 is adjusted according to the pupil position so that the lens is aligned with the pupil. Magnetic blocks 3077 are evenly set at the slide groove 3076, and the magnetic blocks 3077 are set corresponding to the first alignment opening 3072. The magnetic blocks 3077 are attracted to fix the magnetic sheet 3081, thereby fixing the position of the installation component 308 to prevent the lens from being misaligned with the pupil position. And by setting the second alignment opening 3074, the position of the lens can be detected and adjusted after the lens is installed. If the lens position is misaligned with the second alignment opening 3074, the position of the sliding block 3078 is checked, and the sliding block 3078 is readjusted and fixed so that the corresponding magnetic block 3077 is attracted to fix the magnetic sheet 3081.

[0070] Installation component 308 includes:

[0071] A second adjustment rod 3082 is mounted on the outside of the sliding block 3078. An arc-shaped frame plate 3083 is mounted on the outside of the second adjustment rod 3082. The arc-shaped frame plate 3083 has a groove inside and is made of rubber. A third adjustment rod 3084 is mounted on the bottom of the arc-shaped frame plate 3083. A magnetic piece 3081 is mounted on the outside of the sliding block 3078. A lever is mounted on the top of the sliding block 3078.

[0072] A fixed shaft 3085 is connected to the outside of the third adjustment rod 3084. The outside of the fixed shaft 3085 is rotatably connected to the rotating frame 3086. The fixed shaft 3085 is made of rubber.

[0073] Arc-shaped frame 3087, arc-shaped frame 3087 is installed at the bottom of rotating frame 3086, the bottom of arc-shaped frame 3087 is installed with fourth adjusting rod 3088, the bottom of fourth adjusting rod 3088 is installed with L-shaped plate 3089, by manually adjusting the stroke of fourth adjusting rod 3088, the height of L-shaped plate 3089 can be controlled, the interior of L-shaped plate 3089 is provided with card slot, L-shaped plate 3089 is located close to horizontal plate 3071.

[0074] As the sliding block 3078 moves to the magnetic block 3077 , the magnetic piece 3081 on the outside of the sliding block 3078 is attracted and fixed to the magnetic block 3077 , thereby fixing the position of the mounting assembly 308 .

[0075] Manually adjust the stroke of the second adjustment rod 3082 to reserve space for the lens to flip over. Manually insert the lens into the arc frame 3087 from the bottom. Depending on the user's vision, the superimposed lens can be manually inserted into the card slot in the L-shaped plate 3089.

[0076] When the lens needs to be flipped, the arc frame 3087 is manually rotated, and the arc frame 3087 and the rotating frame 3086 begin to rotate outside the fixed shaft 3085, so that the lens can be flipped.

[0077] By setting up the mounting assembly 308, the lenses and the stacked lenses can be placed separately, and the rotating shaft is set to rubber material. There is friction between the rotating shaft and the rotating frame 3086. When the angle of the rotating frame 3086 is manually adjusted, the rotating frame 3086 can stay at different angles to complete the flipping of the lens.

[0078] like Figure 10 As shown, a gear toggle device is provided inside the glasses. As the pupil distance adjustment toggle wheel located above the glasses is turned, the two lenses begin to slide in the built-in grooves at the bottom of the glasses.

[0079] When the interpupillary distance of the lenses in the glasses needs to be adjusted, with the contact 303 touching the center of the user's eyes, the tester, standing on the other side of the device, observes the user's pupil position through the first alignment opening 3072 and records the position of the first alignment opening 3072. The lens in the built-in groove is then manually inserted into the slot in the L-shaped plate 3089. The sliding block 3078 is manually moved to the magnetic block 3077 corresponding to the first alignment opening 3072. The magnetic piece 3081 on the outside of the sliding block 3078 engages with the magnetic block 3077 and is fixed. Simultaneously, the gear shift mechanism inside the glasses begins to move, causing the lens and the sliding block 3078 to move synchronously, thereby adjusting the interpupillary distance of the two lenses.

[0080] Working Principle: Before using the device, manually place it on the table and bring it close to the user. Adjust the lifting mechanism 2 to fix the position of the device.

[0081] Before using the device, manually place the device on the desktop so that the device is at a position near the user at the edge of the table. Subsequently, manually press the pull ring, and the pull ring, the clamping block 211 and the spring 210 move downward until the clamping block 211 is clamped into the circular groove 209. At the same time, the clamping block 211 drives the connecting plate 212 and the suction cup 213 to move downward. The suction cup 213 gradually contacts the desktop and is suction-fixed on the desktop, thereby fixing the position of the device. Subsequently, manually adjust the length of the first adjusting rod 205 so that the heights of the user's eyes are level with the height of the adjusting mechanism 3.

[0082] Before using the device, by adjusting the first adjusting rod 205, the height of the user's nose bridge is equivalent to that of the contact head 303. Manually pull the handle 304, and then adjust the position of the moving rod 302 so that the contact head 303 outside the moving rod 302 contacts the user's nose bridge, so that the contact head 303 is in the center position between the user's two eyes.

[0083] Subsequently, adjust the alignment component 307 to measure the user's interpupillary distance. Before using the device, the lifting rod 206 is in the initial state. As the contact head 303 contacts the middle position between the user's two eyes, the tester is on the other side of the device. Observe the pupil position of the user through the first alignment port 3072. Subsequently, manually move the sliding block 3078 so that the sliding block 3078 moves to the magnet 3077 corresponding to the first alignment port 3072, thereby completing the adjustment of the interpupillary distance and the adjustment of the mounting component 308. As the sliding block 3078 moves to the magnet 3077, the magnetic sheet 3081 outside the sliding block 3078 is suction-fixed to the magnet 3077, thereby fixing the position of the mounting component 308.

[0084] Manually install the lens in the mounting component 308, and then turn on the lifting rod 206 to the first stroke. The position of the device moves upward, and the lens is aligned with the second alignment port 3074, and the interpupillary distance can be observed whether it is correct. Subsequently, turn on the lifting rod 206 to the second stroke. The position of the device moves upward, and adjust the mounting component 308 so that the lens is in its original position. At this time, the lens can be stacked or flipped.

[0085] Manually adjust the stroke of the second adjusting rod 3082 to reserve space for lens flipping. Manually insert the lens into the arc-shaped frame 3087 from the bottom. According to the user's vision condition, the stacked lens can be manually inserted into the card slot in the L-shaped plate 3089.

[0086] When the lens needs to be flipped, manually rotate the arc-shaped frame 3087, and the arc-shaped frame 3087 and the rotating frame 3086 start to rotate outside the fixed shaft 3085, and the lens flipping work can be carried out.
