Description

Technical Field

[0001] The present invention relates to the technical field of optometry trial glasses frames, and in particular to an intelligent anti-shaking, precise and stable optometry trial glasses frame. Background Art

[0002] For eye diseases such as hyperopia and myopia, the most common correction method is to wear glasses. Before choosing glasses, you must have an eye test. Eye test is one of the most basic, most commonly used, but most important tasks in fitting glasses.

[0003] Optometry mainly checks the deformation of the eyeball. Generally, two methods are used. One is to use instruments to check, which can preliminarily measure the deformation of the eyeball and get the patient's initial degree. The other is lens insertion refraction, that is, let the patient try on a trial frame with trial lenses inserted. By constantly changing the trial lenses and repeatedly trying them out, the degree of glasses suitable for the patient is determined. There are two round frames on the trial frame. In layman's terms, the trial frame is a glasses frame that can add or subtract lenses during the refraction process. The axis position is marked on the lens ring of the trial frame, which is needed for astigmatism refraction.

[0004] For example, a Chinese patent with publication number CN219048433U discloses an optometrist trial frame. An optometrist can insert a prescription lens into the curved frame, open the two legs and place them above the patient's ears. By moving the two circular frames, the two racks can drive the gears to rotate, so that the two circular frames move the same distance relative to the middle of the support rod. After the distance between the two circular frames is adjusted according to the patient's pupil distance, the bolt can be turned so that the rear end of the bolt contacts and presses against the rotating shaft, preventing the shaft from rotating.

[0005] Everyone's eye condition is different, and there may be various conditions such as myopia, hyperopia, astigmatism, etc. Therefore, during the optometry operation, in order to know the patient's eye condition more accurately, the optometrist needs to insert different combinations of inserts on the trial frame to find the most suitable vision correction plan for the patient. After the combination is completed, the optometrist often requires the patient to wear the combined trial frame, walk around and take a look, so that the patient can provide timely feedback if there is any discomfort, and then make adjustments.

[0006] When patients move, they are prone to some shaking, and the presence of multiple inserts greatly increases the overall weight of the trial frame, resulting in weaker support from the leg rest. As a result, the trial frame has poor stability on the patient's face, affecting the patient's feedback on the wearing results. In severe cases, the trial frame may be detached from the patient's face, causing damage to the inserts.

[0007] Therefore, there is a need for an intelligent anti-shake, precise and stable optometry trial glasses frame. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to overcome the defects of the existing technology. The present invention proposes an intelligent anti-shake, precise and stable optometry trial frame to solve the problem of poor stability of the trial frame during the wearing process of patients proposed in the above-mentioned existing technology.

[0009] In order to solve the above technical problems, the technical solution adopted by the present invention is: an intelligent anti-shake, precise and stable optometry trial glasses frame, including an adaptive mechanism, frames are provided on both sides of the adaptive mechanism, a squeezing mechanism is provided on the outside of the frame, temples are provided on the outside of the squeezing mechanism, and a sheet frame 1 and a sheet frame 2 are provided on one side of the frame, and an elastic arc sheet is fixedly installed on the outer wall of the sheet frame. When wearing the glasses, the patient first rotates the temples with both hands to open them, and the temples will force the squeezing mechanism to squeeze the gas inside the frame during the rotation process, so that the gas pushes the frame gradually away from the adaptive mechanism, and at the same time, the reset force of the adaptive mechanism is also gradually increasing. Then the patient puts the trial glasses on. After the entire frame is worn on the face, release your hands and rely on the reset potential energy of the adaptive mechanism to pull the frames gradually closer to each other until the temples form a clamp on the patient's face, and the gas in the frame will return part of the original path, and then the gas will push back the temples to make a certain rotation, thereby increasing the clamping force of the temples on the patient's face and improving the overall stability of the trial frame. In the subsequent insertion process, the elastic arc piece will force the lens to squeeze the gas inside the frame one and the frame two, so that the gas enters the adaptive mechanism and the temples at the same time, while increasing the stability between the frame and the patient's nose bridge, the wrapping of the patient's ears is increased, which can further enhance the stability of the trial frame during wearing.

[0010] Furthermore, the adaptive mechanism includes a cavity rod, the upper end of the cavity rod is fixedly mounted with a fixing plate, a groove is formed inside the frame, a piston cylinder is fixedly mounted on the outer wall of the frame, the piston cylinder is connected to the groove, a piston rod is slidably mounted on the inner side of the piston cylinder, and one end of the piston rod is fixedly connected to the fixing plate;

[0011] The squeezing mechanism includes a shell fixedly connected to the outer wall of the frame, a slide rail is symmetrically installed on the inner wall of the shell, a slide rod is slidably installed on the inner wall of the slide rail, an elastic telescopic rod is fixedly installed on the outer wall of the slide rod, and a positioning rod is fixedly installed on the end of the elastic telescopic rod away from the slide rod. Both ends of the positioning rod are rotatably connected to the inner wall of the shell, the positioning rod is fixedly connected to the temple, and a connecting piece is provided on the outer wall rotation sleeve of the slide rod. A piston rod 2 is fixedly installed on one side of the connecting piece, and a piston cylinder 2 is provided on the outer side sliding sleeve of the piston rod 2. One end of the piston cylinder 2 is fixedly connected to the outer wall of the frame, and the piston cylinder 2 is communicated with the groove 1. When the patient rotates the temple, the temple drives the positioning rod to rotate, and the positioning rod drives the slide rod to slide in the slide rail through the elastic telescopic rod. The reason why the slide rod can slide horizontally in the slide rail is that the position distance required for the slide rod to slide is compensated by the adaptive expansion and contraction of the elastic expansion rod, and the slide rod pushes the piston rod 2 gradually deeper into the piston cylinder 2 through the connecting piece during the sliding process, thereby squeezing the gas inside the piston cylinder 2, and the squeezed gas will enter the groove 1, and then enter the piston cylinder 1. As the gas inside the piston cylinder 1 increases, the piston rod 1 is pushed to gradually extend out from the inside of the piston cylinder 1. Since one end of the piston rod 1 is restricted by the fixed plate, the piston rod 1 pushes the frame as a whole away from the cavity rod, which greatly increases the distance between the two sets of temples, making it easier to adapt to the subsequent wearing of patients with different specifications.

[0012] Furthermore, a connecting rod is fixedly installed on the outer wall of the frame, and the connecting rod is slidably connected to the inner wall of the cavity rod. A spring 1 is fixedly installed on the end of the two groups of connecting rods that are close to each other. When the two groups of frames move away from each other, they will drive the two groups of connecting rods to pull the spring 1 in opposite directions, so that the spring 1 is gradually stretched and its reset force is gradually increased. After the patient wears the trial frame as a whole on the face, the force is gradually loosened. At this time, the connecting rod is pulled by the reset force of the spring 1, and the frames are brought closer to each other until the temples and the patient's face are clamped. At the same time, the two groups of piston cylinders 1 will also approach each other, so that the piston rod 1 penetrates into the piston cylinder 1, which causes the gas in the piston cylinder 1 to be squeezed, so that part of the gas returns to its original path, and then the gas pushes back the temples to rotate a certain amount, thereby increasing the clamping force of the temples on the patient's face and improving the overall stability of the trial frame.

[0013] Furthermore, a one-way valve 1 is fixedly installed on one side of the cavity rod, a sleeve is fixedly installed on the lower end of the cavity rod, and a driven rod is slidably installed on the inner wall of the sleeve, and a connecting rod is fixedly installed on the lower end of the driven rod, and a nose pad is fixedly installed on one side of the connecting rod, a one-way valve 2 is fixedly installed on the upper end of the sleeve, and a one-way valve 3 is fixedly installed on one side of the driven rod. In the process of the two sets of connecting rods moving away from each other, due to the expansion of the internal space of the cavity rod, the one-way valve 1 is prompted to be opened to replenish air into the space. When the spring 1 returns and pulls the two sets of connecting rods closer to each other, it will squeeze the front replenished air, prompting the one-way valve 2 to be opened, and then discharge the air into the sleeve and the driven rod, thereby pushing the driven rod to drive the connecting rod and the nose pad to move downward together until the nose pad contacts and presses against the patient's nose bridge, and the excess air will prompt the one-way valve 3 to be opened and discharged, thereby forming an adaptive clamping for the patient's face while completing the adaptive support of the nose pad for the patient's nose bridge, which is highly practical.

[0014] Furthermore, the structures of frame one and frame two are the same. Frame one includes multiple groups of clips fixedly connected to each other. A group of clips closest to the frame is fixedly connected to it. The outer wall of each group of clips is fixedly connected to the elastic arc piece. When the optometrist inserts the insert, the elastic arc piece will first deform. When the insert contacts the clip, the elastic arc piece returns to its initial position. At this time, the elastic arc piece and the clip together form a clamping fixation for the insert, thereby preventing the insert from shaking and detaching, thereby improving the accuracy of eye examination.

[0015] Furthermore, a second groove is provided inside the frame, and air pipes are slidably mounted on the inner sides of both ends of the connecting rod, and the air pipes are connected to the second groove. An elastic member is provided on the inner side of the clamping member, and a third groove is provided inside the clamping member. Through holes are provided on one side of the group of clamping members farthest from the frame and on both sides of the remaining multiple groups of clamping members, and the multiple through holes correspond to each other and are connected to the second groove.

[0016] The elastic member includes a spring 2 fixedly connected to the third surface of the groove, and a pressing piece is fixedly installed on one end of the spring 2 away from the third surface of the groove, and the pressing piece is slidably connected to the third surface of the groove;

[0017] The nose support comprises two groups of arc-shaped cavity rods fixedly connected and communicated with the connecting rod, an arc-shaped rod is slidably installed inside the arc-shaped cavity rod, and a rubber support plate is provided at one end of the arc-shaped rod. Whenever a piece of insert is inserted, the pressure plate will be pushed to squeeze the gas in slot three under the reset force of the elastic arc plate, so that the gas in slot three will enter the through hole, slot two, trachea, connecting rod in turn, and finally enter the arc-shaped cavity rod, thereby pushing the arc-shaped rod to drive the rubber support plate to increase the contact force on the patient's nose bridge. When the insert is replaced or removed, the gas is withdrawn under the reset force of spring two, which will reduce the contact force on the patient's nose bridge, so that the contact force between the rubber support plate and the patient's nose bridge can be synchronously matched with the number of inserts, so that the wearing comfort of the patient can be improved as much as possible while ensuring the effective support of the rubber support plate to the entire trial glasses frame.

[0018] Furthermore, a fixing ball is fixedly installed at one end of the arc-shaped rod, and the fixing ball is movably connected to one side of the rubber support plate, so that the rubber support plate can adaptively abut according to the shape of the patient's nose bridge, thereby fitting more closely. On the one hand, it can effectively improve the patient's comfort during wearing, and on the other hand, it can make the support stability of the nose pad better.

[0019] Furthermore, a telescopic plate is symmetrically installed on the outer wall of the trachea, which is fixedly connected to the surface of the second groove. A screw cap is threadedly installed on one side of the driven rod. Through the setting of the telescopic plate and the sliding connection between the trachea and the connecting rod, the internal gas can be kept constant regardless of whether it follows the driven rod for lifting and lowering movement or follows the frame for horizontal movement, thereby ensuring the effect. When the trial frame is used, the patient unscrews the screw cap, pushes the driven rod upward to discharge the internal gas, and then screws on the screw cap for easy use next time.

[0020] Furthermore, the temples include a leg one fixedly connected to the positioning rod, a spring three fixedly installed on the inner wall of the leg one, and a leg two fixedly installed on one end of the spring three. During the process of rotating the leg one, the patient can adjust the overall length of the temple by pulling the leg two to better suit himself.

[0021] Furthermore, a groove four is provided inside the frame, and the sheet frame two is connected to the groove four. A gas rod is fixedly installed on the outer wall of the frame, and the gas rod is connected to the groove four. A bent leg is slidably installed inside the leg two, and the bent leg is magnetically attracted to the leg two. The leg one will match the gas rod during the rotation process. Whenever a piece of insert is inserted, the resetting force of the elastic arc piece will prompt the gas to enter the groove four, the gas rod, the leg one in sequence from the sheet frame two, and finally enter the leg two, thereby pushing the bent leg to extend a distance from the leg two, so that it can fit the patient's ear more closely, so that the degree of fit between the bent leg and the patient's ear can be synchronously matched with the number of inserts, while trying to improve the patient's wearing comfort.

[0022] Compared with the prior art, the beneficial effects of the present invention include: when wearing, the patient first rotates the temples with both hands to open them, and the temples will force the squeezing mechanism to squeeze the gas inside the frame during the rotation process, so that the gas pushes the frame gradually away from the adaptive mechanism. At the same time, the reset force of the adaptive mechanism is also gradually increasing. Then the patient wears the trial frame as a whole on the face and releases his hands. Relying on the reset potential energy of the adaptive mechanism, the two sets of frames are pulled gradually closer to each other until the temples and the patient's face form a clamp, and the gas in the frame will return part of the original path, thereby causing the gas to push back the temples to rotate a certain amount, thereby increasing the clamping force of the temples on the patient's face and improving the overall stability of the trial frame. In the subsequent insertion process, the elastic arc plate will force the lens to squeeze the gas inside the lens frame one and the lens frame two, so that the gas enters the adaptive mechanism and the temples at the same time, while increasing the stability between the lens and the patient's nose bridge, increasing the wrapping of the patient's ears, and further enhancing the stability of the trial frame during wearing.

[0034] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.

[0035] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0036] According to one embodiment of the present invention, Figure 1-3The figure shows an intelligent anti-shake, precise and stable optometry trial frame, comprising an adaptive mechanism 1, frames 2 are provided on both sides of the adaptive mechanism 1, a squeezing mechanism 3 is provided on the outside of the frame 2, temples 4 are provided on the outside of the squeezing mechanism 3, a sheet frame 1 5 and a sheet frame 2 6 are provided on one side of the frame 2, and an elastic arc sheet 7 is fixedly installed on the outer wall of the sheet frame 1. When wearing the glasses, the patient first rotates the temples 4 with both hands to open them, and the temples 4 will force the squeezing mechanism 3 to squeeze the gas inside the frame 2 during the rotation process, so that the gas pushes the frame 2 gradually away from the adaptive mechanism 1, and at the same time, the reset force of the adaptive mechanism 1 is also gradually increasing. Then the patient wears the trial frame as a whole After the patient has put the glasses on, release your hands and rely on the reset potential energy of the adaptive mechanism 1 to pull the frames 2 gradually closer to each other until the temples 4 clamp the patient's face. The gas in the frame 2 will return to its original path, causing the gas to push the temples 4 back to rotate a certain amount, thereby increasing the clamping force of the temples 4 on the patient's face and improving the overall stability of the trial frame. In the subsequent insertion process, the elastic arc piece 7 will force the lens to squeeze the gas inside the frame 1 5 and the frame 2 6, causing the gas to enter the adaptive mechanism 1 and the temples 4 at the same time, increasing the stability between the frame and the patient's nose bridge and increasing the wrapping of the patient's ears, which can further enhance the stability of the trial frame during wearing.

[0037] According to one embodiment of the present invention, Figure 4 as well as Figure 6-8 As shown, the adaptive mechanism 1 includes a cavity rod 11, a fixing plate 115 is fixedly mounted on the upper end of the cavity rod 11, a groove 21 is formed inside the frame 2, a piston cylinder 27 is fixedly mounted on the outer wall of the frame 2, the piston cylinder 27 is connected to the groove 21, a piston rod 28 is slidably mounted on the inner side of the piston cylinder 27, and one end of the piston rod 28 is fixedly connected to the fixing plate 115;

[0038] The squeezing mechanism 3 includes a shell 31 fixedly connected to the outer wall of the frame 2, and a slide rail 311 is symmetrically installed on the inner wall of the shell 31. A slide rod 32 is slidably installed on the inner wall of the slide rail 311, and an elastic telescopic rod 33 is fixedly installed on the outer wall of the slide rod 32. A positioning rod 34 is fixedly installed on the end of the elastic telescopic rod 33 away from the slide rod 32. Both ends of the positioning rod 34 are rotatably connected to the inner wall of the shell 31, and the positioning rod 34 is fixedly connected to the temple 4. A connecting piece 35 is rotatably sleeved on the outer wall of the slide rod 32, and a piston rod 2 36 is fixedly installed on one side of the connecting piece 35. A piston cylinder 2 37 is slidably sleeved on the outer side of the piston rod 2 36. One end of the piston cylinder 2 37 is fixedly connected to the outer wall of the frame 2, and the piston cylinder 2 37 is communicated with the groove 1 21. When the patient rotates the temple 4, the temple 4 drives the positioning rod 34 to rotate, and the positioning rod 34 is driven by the elastic telescopic rod 33 The slide rod 32 slides in the slide rail 311. The slide rod 32 can slide horizontally in the slide rail 311 because the adaptive expansion and contraction of the elastic expansion rod 33 makes up for the position distance required for the slide rod 32 to slide. During the sliding process, the slide rod 32 pushes the piston rod 2 36 gradually into the piston cylinder 2 37 through the connecting piece 35, thereby squeezing the gas inside the piston cylinder 2 37. The squeezed gas will enter the groove 1 21 and then enter the piston cylinder 1 27. As the gas inside the piston cylinder 1 27 increases, the piston rod 1 28 is pushed to gradually extend from the inside of the piston cylinder 1 27. Since one end of the piston rod 1 28 is restricted by the fixed plate 115, the piston rod 1 28 pushes the frame 2 as a whole away from the cavity rod 11, so that the distance between the two sets of temples 4 is greatly increased, which is convenient for adapting to the subsequent wearing of patients with different specifications.

[0039] According to one embodiment of the present invention, Figure 3 As shown, a connecting rod 25 is fixedly installed on the outer wall of the frame 2, and the connecting rod 25 is slidably connected to the inner wall of the cavity rod 11. A spring 26 is fixedly installed at one end of the two groups of connecting rods 25 that are close to each other. When the two groups of frames 2 move away from each other, they will drive the two groups of connecting rods 25 to pull the spring 26 in opposite directions, so that the spring 26 is gradually stretched, and its reset force is gradually increased. After the patient wears the trial frame as a whole on the face, the force is gradually loosened. At this time, the connecting rod 25 is pulled by the reset force of the spring 26, and the frames 2 are brought closer to each other until the temple 4 and the patient's face are clamped. At the same time, the two groups of piston cylinders 27 will also approach each other, so that the piston rod 28 penetrates into the piston cylinder 27, which causes the gas in the piston cylinder 27 to be squeezed, thereby causing the gas to return to its original path, and then the gas pushes back the temple 4 to rotate a certain amount, thereby increasing the clamping force of the temple 4 on the patient's face and improving the overall stability of the trial frame.

[0040] According to one embodiment of the present invention, Figure 6-7As shown, a one-way valve 113 is fixedly installed on one side of the cavity rod 11, a sleeve 112 is fixedly installed on the lower end of the cavity rod 11, a driven rod 12 is slidably installed on the inner wall of the sleeve 112, a connecting rod 121 is fixedly installed on the lower end of the driven rod 12, a nose piece 124 is fixedly installed on one side of the connecting rod 121, a one-way valve 2 114 is fixedly installed on the upper end of the sleeve 112, and a one-way valve 3 125 is fixedly installed on one side of the driven rod 12. In the process of the two groups of connecting rods 25 moving away from each other, due to the expansion of the internal space of the cavity rod 11, the one-way valve 113 is opened, and the space is opened. Internal air replenishment, when the spring 1 26 is reset and pulls the two sets of connecting rods 25 closer to each other, it will squeeze the front air replenishment, prompting the one-way valve 2 114 to be opened, and then discharge the gas into the sleeve 112 and the driven rod 12, thereby pushing the driven rod 12 to drive the connecting rod 121 and the nose pad 124 to move downward together, until the nose pad 124 comes into contact with the patient's nose bridge and presses tightly, and the excess gas will prompt the one-way valve 3 125 to be opened and discharged, thereby forming an adaptive clamping of the patient's face while completing the adaptive support of the nose pad 124 on the patient's nose bridge, which is highly practical.

[0041] According to one embodiment of the present invention, Figure 1-3 as well as Figure 5 As shown, the structures of the lens rack 1 5 and the lens rack 2 6 are the same. The lens rack 1 5 includes multiple groups of clips 51 fixedly connected to each other. The group of clips 51 closest to the frame 2 is fixedly connected to it. The outer wall of each group of clips 51 is fixedly connected to the elastic arc piece 7. When the optometrist inserts the insert, the elastic arc piece 7 will first be deformed. When the insert contacts the clip 51, the elastic arc piece 7 returns to its initial position. At this time, the elastic arc piece 7 and the clip 51 together form a clamping fixation for the insert, thereby preventing the insert from shaking and detaching, thereby improving the accuracy of eye examination.

[0042] According to one embodiment of the present invention, Figure 4-7 As shown, a second groove 22 is provided inside the frame 2, and air pipes 122 are slidably mounted on the inner sides of both ends of the connecting rod 121. The air pipes 122 are connected to the second groove 22. An elastic member 52 is provided on the inner side of the clamping member 51. A third groove 511 is provided inside the clamping member 51. One side of the group of clamping members 51 farthest from the frame 2 and both sides of the remaining multiple groups of clamping members 51 are penetrated by through holes 512. The multiple through holes 512 correspond to each other one by one and are connected to the second groove 22.

[0043] The elastic member 52 includes a second spring 522 fixedly connected to the surface of the third groove 511. A pressing piece 521 is fixedly installed on one end of the second spring 522 away from the surface of the third groove 511. The pressing piece 521 is slidably connected to the surface of the third groove 511.

[0044] The nose support 124 includes two groups of arc-shaped cavity rods 1241 fixedly connected and communicated with the connecting rod 121. An arc-shaped rod 1242 is slidably installed inside the arc-shaped cavity rod 1241. A rubber support plate 1244 is provided at one end of the arc-shaped rod 1242. Whenever a piece of inserting is inserted, the resetting force of the elastic arc piece 7 pushes the pressing piece 521 to squeeze the gas in the groove 3 511, so that the gas in the groove 3 511 enters the through hole 512, the groove 22, the trachea 122, the connecting rod 121 in sequence, and finally enters the nose support 124. The spring 1242 is inserted into the arc-shaped cavity rod 1241, thereby pushing the arc-shaped rod 1242 to drive the rubber support plate 1244 to increase the contact force on the patient's nose bridge. When the insert is replaced or removed, the gas is withdrawn under the reset force of the spring 2 522, which will reduce the contact force on the patient's nose bridge, so that the contact force between the rubber support plate 1244 and the patient's nose bridge can be synchronously matched with the number of inserts, so as to maximize the wearing comfort of the patient while ensuring the effective support of the rubber support plate 1244 to the entire trial frame.

[0045] According to one embodiment of the present invention, Figure 7 As shown, a fixing ball 1243 is fixedly installed at one end of the arc rod 1242, and the fixing ball 1243 is movably connected to one side of the rubber support plate 1244, so that the rubber support plate 1244 can adaptively abut according to the shape of the patient's nose bridge, thereby fitting more closely. On the one hand, it can effectively improve the patient's comfort during wearing, and on the other hand, it can make the support stability of the nose support member 124 better.

[0046] According to one embodiment of the present invention, Figure 6-7 As shown, the outer wall of the trachea 122 is symmetrically installed with a telescopic plate 123, and the telescopic plate 123 is fixedly connected to the surface of the groove 22. A screw cap 116 is threadedly installed on one side of the driven rod 12. Through the setting of the telescopic plate 123 and the sliding connection between the trachea 122 and the connecting rod 121, the internal gas can be kept constant regardless of following the driven rod 12 for lifting and lowering movement or following the frame 2 for horizontal movement, thereby ensuring the effect. When the trial frame is used, the patient unscrews the screw cap 116, pushes the driven rod 12 upward to discharge the internal gas, and then screws on the screw cap 116 for the next use.

[0047] According to one embodiment of the present invention, Figure 9 As shown, the temple 4 includes a leg 1 41 fixedly connected to the positioning rod 34, a spring 3 43 is fixedly installed on the inner wall of the leg 1 41, and a leg 2 42 is fixedly installed on one end of the spring 3 43.
