[0046] In summary, this trial frame 100 can adaptively adjust the position of the nose pad 140 to meet the usage needs of the user, improve the adaptability to the user, thereby improving the wearing comfort and improving the fitting experience.

[0047] Further, please refer to Figures 1-5 , in this embodiment, when configuring the spectacle frame 110, the spectacle frame 110 is configured with two lens rings, and the two lens holders 130 respectively correspond to the two lens rings; based on this, in order to facilitate the placement of the optometry lenses corresponding to the lens rings, therefore, each lens holder 130 includes a first lens support 131 and a second lens support 132. Both the first lens support 131 and the second lens support 132 are connected to the spectacle frame 110, and the first lens support 131 and the second lens support 132 are distributed on both sides of the spectacle frame 110. The first lens support 131 and the second lens support 132 are both arranged around the edge of the corresponding lens ring to support the lens; wherein, the first lens support 131 and the temple 120 are located on the same side of the spectacle frame 110, and the connecting frame 142 is connected to the first lens support 131. Thus, through the above structural arrangement, the connection mode of the two nose pads 140 to the first lens support 131 can be achieved, and further the installation steps can be simplified.

[0048] When configuring the first lens support 131, the first lens support 131 includes a first lens holder 1311, a second lens holder 1312 and a first connecting pin 1313; the first lens holder 1311 and the second lens holder 1312 are distributed on both sides of the corresponding lens ring, and the first lens holder 1311 and the second lens holder 1312 are connected to the spectacle frame 110 through the first connecting pin 1313, and the connecting frame 142 is connected to the first lens holder 1311 or the first connecting pin 1313 protruding from the first lens holder 1311. It should be noted that in this embodiment, when setting the connecting frame 142 and the first lens holder 1311, the connection mode of the connecting frame 142 to the first lens holder 1311 is adopted. On this basis, in order to simplify the installation steps, the connecting frame 142 and the first lens holder 1311 can also be integrally formed.

[0049] Further, please refer to Figures 1-7 , in this embodiment, on the basis of the above structure, the lens holder 130 further includes a rotating disk 133. The rotating disk 133 is rotatably connected to the spectacle frame 110, and the second lens support 132 is connected to the rotating disk 133. Through such a setting method, the purpose is to enable the lens placed on the second lens support 132 to rotate synchronously when the rotating disk 133 rotates relative to the spectacle frame 110, and further the installation position of the lens can be adjusted. Such a setting method aims to be able to adjust the lens according to the needs of the user. The specific adjustment functions are as follows:

[0050] Degree adjustment: The lenses on the trial frame usually have different degrees. By rotating the lenses, different degree lenses can be replaced to help the optometrist find the most suitable degree for the customer; Axis adjustment: For customers with astigmatism, in addition to the degree, the axis of the lens needs to be adjusted. Rotating the lens can change the axis to adapt to the customer's astigmatism; PD (Pupillary Distance) adjustment: Although the PD is usually measured during the eye examination, during the trial fitting process, the customer can fine-tune the PD by rotating the lens to ensure that the optical center of the lens is aligned with the pupil center; Vertex distance adjustment: Rotating the lens can fine-tune the distance between the lens and the eye to obtain the best visual effect; Adaptability test: By rotating the lens during the trial fitting process, the customer can experience the visual effects at different degrees and axes, helping them better adapt to and select the lenses suitable for themselves; Comfort test: Rotating the lens can also help the customer test the comfort of the frame 110 to ensure that the combination of the frame 110 and the lens is both beautiful and comfortable.

[0051] Further, please refer to Figures 1-12 , when configuring the second lens holder 132, the second lens holder 132 may include two lens holder bodies 1321 and two spring insert feet 1322; the two lens holder bodies 1321 are connected to the rotating disk 133 at intervals around the rotation axis of rotation; each lens holder body 1321 is provided with at least one lens groove for accommodating the lens; each spring insert foot 1322 is correspondingly connected to a lens holder body 1321 through a pressing plate 1323 and is used for clamping with the lens assembled in the corresponding lens holder body 1321. Such a setting method aims to replace the way of connecting the spring insert foot 1322 and the lens holder body 1321 with bolt connectors through the setting of the pressing plate 1323 to increase the installation stability of the spring insert foot 1322; in addition, by setting two spring insert feet 1322, the deformation amount of a single spring insert foot 1322 when the lens is inserted into the lens groove is reduced, so that the external force when inserting the lens is distributed to the two spring insert feet 1322, facilitating the reduction of the insertion difficulty of the lens and improving the loading stability of the lens.

[0052] Please refer to Figures 1-12, and when rotating the rotating disk 133, in order to control its rotation state, that is, to be able to rotate it and to keep its position unchanged after rotating to an appropriate position. Therefore, the lens holder 130 further includes a limit disk 134 and a limit snap spring 135. The limit disk 134 is connected to the rotating disk 133, and a plurality of limit teeth 136 are arranged around the outer circumference of the limit disk 134 along its axis. The limit snap spring 135 is connected to the lens frame 110 and is used to engage with one of the limit teeth 136 to limit the rotation of the rotating disk 133 relative to the lens frame 110. Through such a setting method, on the basis of the connection between the limit disk 134 and the rotating disk 133, the rotation of the rotating disk 133 relative to the lens frame 110 can be restricted by the engagement of the limit snap spring 135 with one of the limit teeth 136. When it is necessary to rotate the rotating disk 133, an external force is applied to the rotating disk 133 or the limit disk 134 to overcome the clamping force between the limit tooth 136 and the limit snap spring 135; and in the state where the external force disappears, the clamping force between the limit tooth 136 and the limit snap spring 135 can keep the installation of the rotating disk 133 unchanged.

[0053] It should also be noted that, please refer to Figure 8 and Figure 9 , a plurality of scale marks are arranged on the surface of the lens frame 110. The plurality of scale marks are arranged at intervals in a ring shape on the periphery of the lens ring, and the central angle between adjacent scale marks is 5°. Based on this, the interval between adjacent limit teeth 136 can be made the same as 5°. Thus, when the rotating disk 133 rotates, when it rotates one tooth at a time, the corresponding rotation angle is 5°, so that when the rotating disk 133 rotates, it can correspond to the scale marks on the outer periphery to facilitate measuring the rotation degree; and in this embodiment, the angular interval between adjacent scale marks and the angular interval between adjacent limit teeth 136 are both set to 5°. In other embodiments of the present invention, the angular interval between adjacent scale marks and the angular interval between adjacent limit teeth 136 can also be set to other degrees.

[0054] When installing the rotating disk 133, in order to facilitate its rotational connection with the lens frame 110, therefore, a plurality of roller grooves 137 are arranged on the outer circumference of the rotating disk 133, and a roller 138 is correspondingly assembled in each roller groove 137. The roller 138 is used for rolling contact with the lens frame 110. And when installing the rotating disk 133 and the limit disk 134, in order to position their installation positions, therefore, the rotating disk 133 is provided with a first limit platform 139, and the limit disk 134 is provided with a second limit platform 151. The first limit platform 139 and the limit platform respectively abut against the opposite sides of the lens frame 110.

[0055] For the convenience of installing the optometry lenses, therefore, at least one lens groove for accommodating the optometry lenses is provided in both the first lens holder 131 and the second lens holder 132; and such a setting method enables two optometry lenses to be placed simultaneously on the front side of the spectacle frame, while one optometry lens can be placed on the back side thereof. Based on the above content, please refer to Figures 1-12 , in this embodiment, to improve the stability of the user when wearing the trial frame 100, therefore, one end of each temple 120 away from the spectacle frame 110 is bent towards the direction of the other temple 120 to abut against the back of the wearer's head. That is, through such a setting method, while the temples 120 are hooked on the wearer's ears, the end of the temple 120 away from the spectacle frame 110 can also abut against the back of the wearer's head, thereby improving the stability. Moreover, on this basis, a plurality of anti-slip protrusions 152 are provided on one side of each temple 120 facing the other temple 120, so that the friction force can be increased through the plurality of anti-slip protrusions 152 to avoid slipping during the wearing process.

[0056] Based on the above content, please refer to Figures 1-12 , the present utility model also provides a trial lens kit, which includes a plurality of optometry lenses and the above-mentioned trial frame 100; the lens holder 130 is used for plugging one or more optometry lenses. During use, according to the optometry degree, the appropriate optometry lenses can be selectively placed in the lens grooves of the trial frame 100 for the user to wear. During the wearing process, the trial frame 100 is provided with an adjustable nose pad 140 to improve the wearing comfort, and through the setting of the temples 120, the situation of slipping can be avoided, the wearing stability can be improved, and thus the fitting experience can be improved.

[0057] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, various changes and modifications can be made to the present utility model.
