[0031] Please refer to Figure 1-Figure 4 , this embodiment provides an adjustable temple 200, the adjustable temple 200 includes a temple frame 210, a connecting rod 220 and an ear support 230;
[0032] The temple frame 210 is used to be connected to the trial glasses frame; one end of the connecting rod 220 is movably connected to the temple frame 210 , and the other end of the connecting rod 220 is connected to the ear support 230 .
[0033] Please refer to Figure 1-Figure 4 The working principle of the adjustable temple 200 is:
[0034] The adjustable temple 200 includes a temple frame 210, a connecting rod 220 and an ear support 230; the temple frame 210 is used to connect to the trial glasses frame; one end of the connecting rod 220 is movably connected to the temple frame 210, and the other end of the connecting rod 220 is connected to the ear support 230. In particular, since the connecting rod 220 of the adjustable temple 200 is movably connected to the temple frame 210, during use, the angle of the adjustable temple 200 can be adjusted by the movement of the connecting rod 220 relative to the temple frame 210, so that the trial glasses frame using the adjustable temple 200 can adaptively adjust the angle of the temple according to the needs of use, thereby adjusting the wearing angle, thereby improving the fit, adaptability and comfort of wearing;
[0035] In summary, the adjustable temple 200 has a simple structure and is easy to use. It can meet the wearing needs of different scenarios or different users by adjusting the angle of the temple, thereby improving the wearing experience.
[0036] It should be noted that, in this embodiment, based on the above-mentioned adjustable temple 200, a trial frame is also disclosed, which includes a frame and at least one of the above-mentioned adjustable temples 200; and a temple frame 210 is connected to the frame. The trial frame adopts the above-mentioned adjustable temple 200 and thus has all the advantages of the adjustable temple 200, and when the adjustable temple 200 is used, one or two adjustable temples 200 can be configured.
[0037] It should also be noted that after the adjustable temple 200 is connected to the frame, the temple frame 210 is rotatably connected to the frame, so that the adjustable temple 200 can be folded onto the frame for easy storage of the trial frame.
[0038] For further information, please refer to Figure 1-Figure 4 In the present embodiment, when the connecting rod 220 is movably connected to the temple rod, the connecting rod 220 is rotatably connected to the temple frame 210, and the axis direction of its rotation can be at an angle to the axis direction of the rotation and folding of the temple frame 210, which is vertical in the present embodiment.
[0039] Specifically, in the present embodiment, when configuring the temple frame 210, the temple frame 210 is configured with an active cavity 211, and one end of the connecting rod 220 for connecting with the temple frame 210 is configured with a rotating connecting portion 221. Based on such a structural arrangement, the rotating connecting portion 221 can be rotatably arranged in the active cavity 211, and the outer peripheral surface of the rotating connecting portion 221 is configured with an external tooth group 222 around its rotation axis relative to the active cavity 211.
[0040] The adjustable temple 200 further includes a driving rod 240 rotatably connected to the temple frame 210, at least a portion of the driving rod 240 is accommodated in the active cavity 211, and an outer peripheral surface of the portion of the driving rod 240 located in the active cavity 211 is provided with a helical tooth group 241 meshing with the outer tooth group 222;
[0041] Therefore, through the above-mentioned structural setting, the driving rod 240 can be operated to rotate relative to the temple frame 210, thereby causing the outer tooth group 222 meshing with the bevel tooth group 241 to rotate, and then driving the connecting rod 220 to rotate relative to the temple frame 210, so that the angle of the ear pad 230 relative to the temple is changed. It should be noted that the aforementioned adjustment method can be adjusted when the adjustable temple 200 is in an unfolded state relative to the frame. Its function is to adjust the angle of the ear pad 230 relative to the frame, thereby adjusting the wearing angle to improve the wearing experience.
[0042] For easy operation, the adjustable temple 200 further includes an operating wheel 242, which is located outside the active cavity 211 and connected to the driving rod 240. In this arrangement, the connecting rod 220 can be driven to rotate relative to the temple frame 210 by twisting the operating wheel 242.
[0043] After the angle of the temple frame 210 is adjusted to a suitable position, in order to prevent the relative angle of the ear support 230 from changing during the wearing of the trial frame, please refer to Figure 1-Figure 4 The adjustable temple 200 further includes a stopper 260 , which is used to abut against the driving rod 240 to limit the rotation of the driving rod 240 .
[0044] When configuring the limit member 260, the present embodiment adopts that the limit member 260 is movably arranged in the movable cavity 211; the part of the driving rod 240 located in the movable cavity 211 is also provided with a plurality of limit grooves 243, and the plurality of limit grooves 243 are arranged around the axis of the driving rod 240, and the limit member 260 is used to abut against one of the limit grooves 243.
[0045] In addition, the limiting member 260 includes a limiting rod 261 and an elastic member 262 . The limiting rod 261 is connected to the elastic member 262 . The limiting rod 261 is used to abut against one of the limiting grooves 243 . The elastic member 262 is used to make the limiting rod 261 have a tendency to move toward the driving rod 240 .
[0046] Therefore, through the structural setting of the above-mentioned limit member 260, when the driving rod 240 is not subjected to the action of external force, the rotation of the driving rod 240 in the movable cavity 211 can be limited by the abutment between the limit rod 261 and the limit groove 243; and when adjusting the angle, the driving rod 240 can overcome the abutment resistance between the limit rod 261 and the limit groove 243 under the action of external force.
[0047] While configuring the limiter 260, in order to limit the movable travel of the limiter rod 261, in order to avoid the situation that the external force limiting the rotation of the drive rod 240 is too large during use, and the external force limiting the rotation of the drive rod 240 disappears, please refer to Figure 1-Figure 4 A movable groove 212 is arranged in the movable cavity 211, and a limit platform 263 cooperating with the movable groove 212 is arranged on the outer peripheral surface of the limit rod 261; along the movable direction of the limit member 260, the width of the movable groove 212 is greater than the width of the limit platform 263; thus, under the action of the aforementioned elastic member 262, the limit rod 261 can move toward the direction of the driving rod 240. At this time, the limit platform 263 is located in the movable groove 212, and when the driving rod 240 rotates under the action of external force, the limit rod 261 will move relative to the movable groove 212 in the direction of the elastic member 262 under the action of the external force of the driving rod 240.
[0048] Based on the above structure, please refer to Figure 1-Figure 4 When configuring the connecting rod 220, in order to enable it to adjust the length of the temple according to different needs, the connecting rod 220 includes a rod body 223 and a rod sleeve 224, and the rod body 223 and the rod sleeve 224 are slidably matched, so that the length of the connecting rod 220 can be adjusted by adjusting the length of the rod body 223 in the rod sleeve 224, thereby adjusting the length of the adjustable temple 200.
[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
