[0056] Please refer to Figure 1-Figure 9 , this embodiment provides a trial glasses frame 100, the trial glasses frame 100 includes a frame body 110, temples 120 and an adjustable nose pad 200;

[0057] The frame body 110 includes a lens frame 111 and a main frame 112. The lens frame 111 is connected to the main frame 112, and the lens frame 111 is used to install the trial lens; the temples 120 are connected to the lens frame 111 or the main frame 112;

[0058] The adjustable nose pad 200 includes a main body 210, a rotating member 220, a movable member 230, a nose pad 240, a first adjusting member 250 and a second adjusting member 260; the main body 210 is connected to the main frame 112; the rotating member 220 is rotatably connected to the main body 210, the movable member 230 is slidably connected to the rotating member 220, and the nose pad 240 is connected to the movable member 230; the first adjusting member 250 and the second adjusting member 260 are both movably connected to the main body 210; wherein the first adjusting member 250 is used to drive the movable member 230 to slide relative to the rotating member 220, and the second adjusting member 260 is used to drive the rotating member 220 to deflect relative to the main body 210.

[0059] Therefore, please refer to Figure 1-Figure 9 The working principle of the audition frame 100 is:

[0060] When the adjustable nose pad 200 is installed on the frame body 110, the main body 210 of the adjustable nose pad 200 is connected to the main frame 112. Then, before or after the trial eye lens is installed, the rotating member 220 can be rotated relative to the main body 210 by operating the first adjusting member 250, and the movable member 230 can be slid relative to the rotating member 220 by operating the second adjusting member 260, thereby changing the position of the nose pad 240 connected to the movable member 230 relative to the main frame 112; thereby, the position of the nose pad 240 can be adaptively adjusted to meet the wearing requirements of different users;

[0061] In summary, the trial eyeglass frame 100 using the adjustable nose pad 200 can adjust the nose pad 240 according to the needs of the user, so that the nose pad 240 can adapt to different users, thereby increasing the applicability of the nose pad 240 and improving the wearing experience.

[0062] It should be noted that in the above content, when the first adjusting member 250 is operated to make the movable member 230 slide relative to the rotating member 220, its function is to adjust the distance between the nose pad 240 and the main frame 112, that is, the height of the nose pad 240 is adjusted; and when the rotating member 220 is rotated relative to the main body 210 by operating the second adjusting member 260, its function is to make the rotating member 220 rotate relative to the main frame 112, that is, the angle of the nose pad 240 relative to the main frame 112 is adjusted; therefore, the height and angle of the nose pad 240 can be adjusted by operating the first adjusting member 250 and the second adjusting member 260 during wearing, so as to meet different wearing requirements.

[0063] For further information, please refer to Figure 1-Figure 12 In this embodiment, when configuring the main body 210, in order to facilitate the connection between the main body 210 and the main frame 112, and to install the rotating member 220 or the movable member 230, the main body 210 is provided with an active cavity 211. By setting the active cavity 211, a space for the rotating member 220 and the movable member 230 to move can be provided, and the aesthetics of the trial lens frame 100 can be improved;

[0064] Furthermore, when the rotating member 220 is rotatably connected to the main body 210, the present embodiment adopts that the opposite two side walls of the movable cavity 211 are provided with the first rotating connection part 212; the opposite two sides of the rotating member 220 are provided with the second rotating connection part 221; the first rotating connection part 212 and the second rotating connection part 221 are rotatably matched; wherein one of the first rotating connection part 212 and the second rotating connection part 221 is a rotating connection column, and the other is a rotating connection hole. Such a setting method aims to simplify the structure of the rotating member 220 and the main body 210 and facilitate assembly, and in other embodiments of the present utility model, other structures such as setting a rotating shaft can also be adopted.

[0065] Please refer to Figure 1-Figure 13 When configuring the movable member 230, in order to enable the movable member 230 to be slidably connected to the rotating member 220, a sliding connection hole 222 is opened in the rotating member 220; the movable member 230 and the sliding connection hole 222 are slidably matched, and along the extension direction of the sliding connection hole 222, the two ends of the movable member 230 are respectively connected to the first adjustment member 250 and the nose pad 240.

[0066] On this basis, it can be understood that in the process of operation, since the rotating member 220 is located in the active cavity 211, the rotation of the rotating member 220 can be limited by the abutment between the rotating member 220 and the inner wall of the active cavity 211, and the sliding of the movable member 230 can be limited to prevent it from sliding out of the above-mentioned sliding connection hole 222 during the adjustment process. Therefore, the movable member 230 is provided with a first limiting portion 231, and the sliding connection hole 222 is provided with a second limiting portion 223. The first limiting portion 231 is used to abut against the second limiting portion 223 to limit the movement of the movable member 230 along the extension direction of the sliding connection hole 222 toward the direction away from the first adjustment member 250; wherein, one of the first limiting portion 231 and the second limiting portion 223 is a limiting protrusion, and the other is a limiting groove. In this embodiment, the first limiting portion 231 is a limiting protrusion, and the second limiting portion 223 is a limiting groove;

[0067] It should be noted that, in this embodiment, along the extension direction of the sliding connection hole 222, the first limit portion 231 is disposed at one end of the movable member 230 adjacent to the first adjusting member 250, and the second limit portion 223 is located at one end of the movable connection hole away from the first adjusting member 250. Such a configuration can expand the sliding stroke of the movable member 230 under the driving action of the first adjusting member 250. At the same time, such a configuration can also guide the sliding of the movable member 230 relative to the sliding connection hole 222, thereby preventing the movable member 230 from rotating when the first adjusting member 250 rotates.

[0068] Based on the above content, it can be known that the sliding of the movable member 230 relative to the rotating member 220 and the rotation of the rotating member 220 relative to the main body 210 are respectively controlled by the first adjusting member 250 and the second adjusting member 260. Based on this, the main body 210 is provided with a mounting hole 213 and a threaded hole 214 connected to the movable cavity 211; the first adjusting member 250 is rotatably connected to the mounting hole 213, and one end of the first adjusting member 250 extending into the movable cavity 211 is threadedly connected to the movable member 230; the second adjusting member 260 is threadedly connected to the threaded hole 214, and one end of the second adjusting member 260 extending into the movable cavity 211 is abutted against the rotating member 220.

[0069] Therefore, when the first adjusting member 250 is rotated, since it is rotatably connected to the mounting hole 213, the movable member 230 can be made to slide relative to the rotating member 220 by rotating the first adjusting member 250, and the length of the second adjusting member 260 extending into the active cavity 211 can be adjusted by rotating the second adjusting member 260, thereby driving the rotating member 220 to deflect in the active cavity 211. In the above content, in order to avoid the second adjusting member 260 and the rotating member 220 from getting stuck when the second adjusting member 260 drives the rotating member 220 to deflect in the active cavity 211, the rotating member 220 is provided with a slide groove 224, which extends along the sliding direction of the movable member 230; the second adjusting member 260 is provided with a clamping portion 261, which is engaged with the slide groove 224; through such a setting, the clamping portion 261 can slide relative to the slide groove 224, so that when the rotating member 220 rotates in the active cavity 211, the clamping portion 261 can change its position in the slide groove 224, thereby avoiding the situation of getting stuck. It should be noted that the clamping portion 261 can be a spherical portion.

[0070] In addition, since the rotating member 220 rotates relative to the movable cavity 211 under the driving action of the second adjusting member 260, the movable member 230 connected to the rotating member 220 will move synchronously. Therefore, in order to avoid the failure or jamming of the threaded connection between the movable member 230 and the first adjusting member 250 after synchronous rotation with the rotating member 220, when configuring the first adjusting member 250, the first adjusting member 250 includes a rotating part 251, a connecting spring 252 and a threaded mating section 253, and the two ends of the connecting spring 252 are respectively connected to the rotating part 251 and the threaded mating section 253, and the threaded mating section 253 is threadedly connected to the movable member 230. By such a setting, the rotating part 251 and the threaded fitting section 253 can be flexibly connected by the connecting spring 252, and then after the rotating member 220 rotates, when the angle of the movable member 230 forms an angle with the rotation axis of the rotating part 251, the connecting spring 252 can maintain the function of connecting the rotating part 251 and the threaded fitting section 253. That is, through the structural setting of the connecting spring 252, while playing the role of connecting the rotating part 251 and the threaded fitting section 253, it can also adapt to the angle change of the rotating part 251 and the threaded fitting section 253, so that when they are at an angle, the rotating effect of the rotating part 251 is transmitted to the threaded fitting section 253, so that after the angle of the nose pad 240 is adjusted by the second adjusting member 260, the height adjustment effect of the first adjusting member 250 on the nose pad 240 can be maintained.

[0071] It should be noted that, from the above content, it can be seen that when the first adjusting member 250 is threadedly connected with the movable member 230, the above-mentioned threaded connection method of the threaded matching section 253 and the movable member 230 is adopted, and at the same time, the movable member 230 can be restricted from rotating by the cooperation of the limiting protrusion and the limiting groove, and then when the rotating part 251 is operated to rotate relative to the main body 210, the threaded matching section 253 can be driven to rotate through the connecting spring 252, so that under the cooperation of the limiting protrusion and the limiting groove, the movable member slides in the extension direction of the limiting groove relative to the limiting groove, thereby avoiding the movable member 230 from rotating during the rotation of the first adjusting member 250.

[0072] Please refer to Figure 1-Figure 13In the present embodiment, when the main body 210 is connected to the frame body 110, in order to simplify the connection steps, the main body 210 is also provided with an assembly connection hole 215 that passes through the main body 210, and the assembly connection hole 215 is used to connect with the frame body 110. In addition, the main body 210 is provided with a positioning hole 216 that is communicated with the movable cavity 211, and the positioning hole 216 is used to install a positioning pin that is positioned and connected with the frame body 110. It should be noted that in the present embodiment, the main body 210 is connected to the cross bar 113 of the main frame body 112. Based on this, the cross bar 113 can be passed through the assembly connection hole 215, and the positioning pin can be passed through the positioning hole 216 to connect with the cross bar 113, so that the connection between the main body 210 and the main frame body 112 can be quickly completed.

[0073] For further information, please refer to Figure 14-Figure 21 , and combined with Figure 1-Figure 13 In this embodiment, the lens frame 111 further includes a fixed inserting ring 131, a movable inserting ring 132 and a rotating assembly 140; wherein the movable inserting ring 132 is rotatably connected to the fixed inserting ring 131, and both the fixed inserting ring 131 and the movable inserting ring 132 are provided with a plate holder 133 for installing a trial lens; and when configuring the fixed inserting ring 131 and the movable inserting ring 132, a method is adopted in which the trial lenses installed in the fixed inserting ring 131 and the movable inserting ring 132 are distributed on two opposite sides of the lens frame 111, that is, when configuring the plate holder 133 of the fixed inserting ring 131 and the movable inserting ring 132, a method is adopted in which the plate holder 133 of the fixed inserting ring 131 and the movable inserting ring 132 are installed away from each other;

[0074] In addition, when the movable insert ring 132 is configured, its function is to drive the trial lens installed on the movable insert ring 132 to rotate according to the needs of use. Based on this, this embodiment is also provided with a rotating component 140, which is connected to the lens frame 111 and is used to drive the insert ring to rotate relative to the lens frame 111.

[0075] It should be noted that, in order to enable the movable insert ring 132 to be rotatably connected to the fixed insert ring 131 , the fixed insert ring 131 is provided with an annular groove 134 , the movable insert ring 132 is rotatably connected to the annular groove 134 , and the movable insert ring 132 is pressed by a pressing sheet 135 to prevent it from escaping from the annular groove 134 .

[0076] When configuring the rotating assembly 140, the rotating assembly 140 includes an operating rod 141, a driving tooth 142 and a limit member 143. Based on this, in order to facilitate the installation of the rotating assembly 140, the fixed plug ring 131 is provided with an operating cavity 136, and the movable plug ring 132 is provided with an annular rack 137 on the side facing the fixed plug ring 131, and the operating cavity 136 is provided with an opening opposite to the annular rack 137; wherein the operating cavity 136 is connected to the annular groove 134 through the opening.

[0077] Thus, the operating rod 141 can be rotatably connected to the operating cavity 136, and the driving tooth 142 can be connected to the portion of the operating rod 141 located in the operating cavity 136, and meshed with the annular rack 137 through the opening. With such an arrangement, the operating rod 141 can be rotated, and the driving tooth 142 can mesh with the annular rack 137, thereby driving the movable insert ring 132 to rotate relative to the fixed insert ring 131.

[0078] In addition, when the movable insert ring 132 is rotated to a suitable position, in order to lock its position, a limiting portion 144 is arranged on the outer periphery of the portion of the operating rod 141 located in the operating cavity 136, and the limiting member 143 is accommodated in the operating cavity 136; and the operating rod 141 can move relative to the operating cavity 136 along its axial direction, and is provided with a limiting portion 144 and abutting against the limiting member 143 to limit the rotational position of the operating rod 141 relative to the operating cavity 136, and the position of being disengaged from the abutment with the limiting member 143, that is, through such an arrangement, after the movable insert ring 132 is rotated to a suitable position by rotating the operating rod 141, the operating rod 141 can be pulled so that the limiting portion 144 on the operating rod 141 abuts against the limiting member 143, thereby limiting the rotation of the operating rod 141, and when it is necessary to rotate the operating rod 141, the operating rod 141 can be driven to move along its axial direction so that the limiting portion 144 and the limiting member 143 are disengaged from the abutment.

[0079] It should be noted that the limiter 143 has a certain deformation ability. When it abuts against the limiter 144, it can undergo elastic deformation and then engage with the limiter 144 to limit the rotation of the operating rod 141.
