[0042] Please refer to Figures 1-4 This embodiment provides a trial frame 100, which includes a frame 110, temples 130, two lens holders 150, and two rotating units 170.
[0043] The frame 110 is equipped with two lens rings 111, and the temples 130 are connected to the frame 110; the two lens holders 150 correspond to the two lens rings 111 respectively, and the two lens holders 150 correspond to the two rotating units 170 respectively. Each lens holder 150 is rotatably connected to the corresponding lens ring 111 through the corresponding rotating unit 170.
[0044] Please refer to Figures 1-4 The working principle of the audition frame 100 is as follows:
[0045] The trial frame 100 includes a frame 110, temples 130, two lens holders 150, and two rotating units 170. The frame 110 is equipped with two lens rings 111, and the temples 130 are connected to the frame 110. The two lens holders 150 correspond to the two lens rings 111 respectively, and the two lens holders 150 correspond to the two rotating units 170 respectively. Each lens holder 150 is rotatably connected to the corresponding lens ring 111 through the corresponding rotating unit 170. This trial frame 100 is used in trial kits. It has a simple structure and is easy to use. During the trial, it allows the operator to easily rotate and adjust the position of the lenses according to the needs, thereby improving the fit of the lens fitting process and increasing the efficiency of the trial.
[0046] It should be noted that during the lens fitting process, the above-described structural arrangement allows the lens frame 150 to rotate relative to the lens rim 111 via the corresponding rotating unit 170. The purpose of this is to adjust the lens mounting position. This arrangement allows for adjustments to the lenses according to the user's needs, with the specific adjustments performed as follows:
[0047] Axis adjustment: For customers with astigmatism, in addition to the prescription, the axis of the lens also needs to be adjusted. Rotating the lens can change the axis to adapt to the customer's astigmatism. Adaptability test: During the trial, customers can rotate the lens to experience the visual effects under different axes, which helps them better adapt to and choose the right lens for themselves.
[0048] Further, please refer to Figures 1-7 In this embodiment, as can be seen from the foregoing, the lens holder 150 is used to support the lens. Therefore, when configuring the lens holder 150, this embodiment makes each lens holder 150 include a first lens holder 151 and a second lens holder 152. The first lens holder 151 and the second lens holder 152 are both connected to the corresponding rotating unit 170, and the first lens holder 151 and the second lens holder 152 are distributed at intervals around the edge of the corresponding lens ring 111 to support the lens.
[0049] Furthermore, the first lens holder 151 is provided with at least one first lens support groove 153, and the second lens holder 152 is provided with at least one second lens support groove 154; wherein, each first lens support groove 153 corresponds to one second lens support groove 154, and each first lens support groove 153 and the corresponding second lens support groove 154 jointly support one or more lenses.
[0050] During the audition process, there may be situations where multiple lenses need to be assembled. Therefore, the lens holder 150 provided in this embodiment is designed to accommodate multiple lenses simultaneously. That is, multiple first lens support slots 153 and second lens support slots 154 are configured, and each first lens support slot 153 corresponds to one second lens support slot 154.
[0051] Further, please refer to Figures 1-8 In this embodiment, as can be seen from the above, each lens holder 150 is rotatably connected to the corresponding lens ring 111 through the corresponding rotating unit 170. Based on this, the two lens holders 150 can rotate independently. Therefore, the two rotating units 170 have the same structural configuration. The structural configuration of one of the rotating units 170 will be described below.
[0052] Specifically, the rotating unit 170 used in this embodiment includes a rotating disk 171, a limiting disk 172, and a limiting member 173;
[0053] The rotating disk 171 is rotatably connected to the lens ring 111, and the limiting disk 172 is connected to the rotating disk 171, and the limiting member 173 is connected to the lens ring 111; the lens holder 150 is connected to the rotating disk 171.
[0054] The limiting member 173 is used to abut against the limiting plate 172 to limit the rotation of the limiting plate 172 and the rotating plate 171 relative to the mirror ring 111.
[0055] Thus, through the above-described structural arrangement, the operator can operate the rotating disk 171 to overcome the rotational resistance of the limiting member 173, thereby causing the rotating disk 171 to rotate relative to the lens ring 111, thereby adjusting the position of the lens connected to the rotating disk 171. Moreover, during this process, the limiting member 173 restricts the rotation of the limiting disk 172 connected to the rotating disk 171, thereby keeping the position of the lens unchanged when the lens rotates to the appropriate position.
[0056] In this embodiment, when the rotating disk 171 is rotatably connected to the lens ring 111, an annular groove 112 is provided on the inner circumference of the lens ring 111, and a sliding part 174 is provided on the outer circumference of the rotating disk 171 to slide in conjunction with the annular groove 112. That is, the rotating disk 171 and the lens ring 111 are rotatably connected by the cooperation between the sliding part 174 and the annular groove 112.
[0057] There are various ways to configure the sliding part 174. For example, the sliding part 174 may include an annular protrusion disposed on the outer periphery of the rotating disk 171. Through the cooperation between the annular protrusion and the annular groove 112, the rotating disk 171 and the mirror ring 111 can be rotatably connected.
[0058] In addition, the sliding part 174 may include at least two sliding members. The outer periphery of the rotating disk 171 is provided with at least two mounting grooves. Each sliding member is installed in a corresponding mounting groove, and the sliding members are spaced apart. The purpose is to enable the rotating disk 171 and the mirror ring 111 to be rotatably connected through the cooperation of the sliding members and the annular groove 112.
[0059] When the limiting plate 172 is configured, its function is to abut against the limiting member 173, thereby limiting the rotation of the rotating plate 171 by restricting the rotation of the limiting plate 172 through the limiting member 173. It should be noted that when the rotating plate 171 is rotated, the operator can overcome the limiting effect of the limiting member 173 to make the rotating plate 171 rotate. When the rotating plate 171 is not subjected to external force, it can maintain its position unchanged under the limiting effect between the limiting member 173 and the limiting plate 172.
[0060] Based on this, multiple limiting teeth 175 can be arranged around the axis of the limiting disk 172 on its outer periphery, and the limiting member 173 engages with one of the limiting teeth 175.
[0061] It should be noted that multiple scale marks are arranged on the surface of the mirror ring 111. These scale marks are arranged in a ring around the periphery of the rotating disk 171, and the included angle between the centers of adjacent scale marks is 1°-5°. The purpose is to allow observation of the rotation angle through the scale ring when the rotating disk 171 is rotated. Based on this, when configuring the limiting disk 172, the interval between adjacent limiting teeth 175 on the limiting disk 172 can be 1°-5°. Thus, when the rotating disk 171 is rotated, if the limiting member 173 and the limiting teeth 175 rotate relative to each other by one tooth, the rotating disk 171 rotates by 1°-5°, thereby allowing its rotation angle to correspond with the external marks, so that the rotation angle can be statistically calculated during rotation. Based on this, in this embodiment, when configuring the limiting teeth 175 and the aforementioned marks, the method adopted is that two adjacent limiting teeth 175 and a single mark scale correspond to 2.5°.
[0062] Based on the above structural setup, please refer to Figures 1-9 When configuring the limiting component 173, this embodiment uses the limiting component 173, which includes a limiting seat 176, a limiting block 177, and a limiting spring 178.
[0063] The limiting seat 176 is connected to the mirror ring 111 and is provided with a limiting groove 181; the limiting block 177 is movably disposed in the limiting groove 181 along the radial direction of the limiting disk 172 and abuts against the limiting spring 178 located in the limiting groove 181.
[0064] The limiting spring 178 is used to make the limiting block 177 tend to move toward a position that engages with the limiting tooth 175.
[0065] Therefore, through the above-described structural arrangement, the limiting block 177 can move within the limiting groove 181, and under the action of the limiting spring 178, it can move towards the limiting disk 172, causing its end to engage with one of the limiting teeth 175, thereby limiting the rotation of the limiting disk 172. When the operator rotates the rotating disk 171, the limiting disk 172 can overcome the limiting effect of the limiting block 177 and thus rotate synchronously. It should be noted that the end of the limiting block 177 facing the limiting disk 172 is provided with a tip that engages with the limiting tooth 175.
[0066] Based on the aforementioned limiting seat 176 structure, the trial frame 100 is further equipped with two nose pads 190, each connected to one of the two lens rings 111, and each nose pad 190 is equipped with a third lens holder 191; the limiting seat 176 is equipped with a fourth lens holder 182; wherein, the third lens holder 191 of the nose pad 190 and the fourth lens holder 182 of the limiting seat 176 connected to the same lens ring 111 jointly support one or more lenses. Moreover, when the aforementioned nose pads 190 and limiting seat 176 are configured, they are located on different sides of the lens ring 111 from the lens holder 150. It should be noted that a support sleeve is detachably connected to the nose pad 190, which is used to support the user's nose.
[0067] Based on the above, please refer to Figures 1-9 The present invention also provides a trial lens kit, which includes multiple optometry lenses and the aforementioned trial lens frame 100; the trial lens frame 100 is used to insert one or more of the optometry lenses.
[0068] During use, appropriate lenses can be selectively inserted into the lens holder of the trial frame 100 according to the prescription, so that the user can wear them. During the trial eye exam, the position of the lenses can be adjusted by rotating the rotating disk 171, thereby improving the fit of the lens fitting process and increasing the efficiency of the trial.
[0069] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
