[0002] In the production process of sunglasses, fatigue tests are required on the temples. These tests require a sunglasses frame fatigue testing device. However, the clamping positions of existing fatigue testing devices are fixed. When fixing temples that are too large or too small, they may become loose, which limits their applicability. Moreover, most existing fatigue testing devices do not have heat dissipation functions.

The technical solution disclosed in this patent document is as follows: A fatigue resistance testing device for sunglasses frames, including a base, with a servo motor fixedly connected to the upper end of the base. This fatigue resistance testing device for sunglasses frames has the function of adjusting the position of the clamp, which can be used to fix temples of different sizes, thus having a wide range of applications. It also has a heat dissipation function, which can promptly expel the temperature inside the control box, protecting the electrical components inside the control box from high temperatures and extending the service life of the electrical components.

[0004] However, there are still cases where the spacing of the fixing clips cannot be adjusted, which leads to the problem of not being able to accommodate different sizes of frames. Utility Model Content

An adjustable rotating mechanism 2 is provided on the surface of the adjustment platform 1, and a clamping assembly 3 is provided on the surface of the adjustable rotating mechanism 2. The adjustable rotating mechanism 2 includes a rotating lifting unit and a transverse moving unit. The transverse moving unit is provided on the surface of the rotating lifting unit, and the rotating lifting unit includes a servo motor 21, a rotating groove rod 22, a lifting rod 23, and a first spring block 24. By setting the long bidirectional screw 12 and the movable seat 13, it is convenient to install the servo motor 21, and the long bidirectional screw 12 can be rotated according to the width of the frame, so that the movable seat 13 drives the clamping assembly 4 to move, thereby adapting to different specifications of frames and improving the range of tests.

[0028] Example 2

[0029] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the bottom surface of the servo motor 21 and the top surface of the moving seat 13 are fixedly connected; the rotating slot rod 22 passes through the top plate of the adjusting table body 11 and is rotatably connected to the output end of the servo motor 21; the lifting rod 23 is inserted and installed on the top of the rotating slot rod 22, and its surface is slidably connected to the inner wall of the rotating slot rod 22; one end of the spring of the first spring block 24 is fixedly connected to the inside of the lifting rod 23; the transverse unit includes a transverse rod 25 inserted and installed on the top of the lifting rod 23, and its surface... The surface of the horizontal moving rod 25 is slidably connected to the inner wall of the lifting rod 23. A second spring block 26 is fixedly installed on the surface of the horizontal moving rod 25. The first spring block 24 is slidably connected to the inner wall of the lifting rod 23 and the rotating groove rod 22, and two sets are provided. The surface of the second spring block 26 is slidably connected to the inner wall of the lifting rod 23. By setting the rotating groove rod 22 and the lifting rod 23, the height of the clamping assembly 3 can be adjusted to accommodate different heights of the eyeglass frame. The clamping position can also be adjusted according to the test requirements to achieve different test results. The spring block can be limited to improve stability.

[0030] Example 3

[0031] like Figure 1-5As shown, based on embodiments 1-2, this utility model provides a technical solution: Preferably, the clamping assembly 3 includes a connecting rod 31 fixedly installed on the top surface of the horizontal moving rod 25. A U-shaped frame 32 is fixedly installed at one end of the connecting rod 31.

Then, the frame is placed on the adjustment table 1. The height of the lifting rod 23 is adjusted by the first spring block 24 on the rotating groove rod 22, so that the temples enter between the clamping blocks 34 on the U-shaped frame 32. Then, the short bidirectional screw 33 can be rotated to adjust the clamping blocks 34 to clamp it. Finally, the servo motor 21 can be started to drive the rotation, so that the clamping assembly 33 can drive the temples to perform a circumferential movement, thereby performing a cyclic fatigue test. The amplitude of the circumferential movement can be adjusted by adjusting the position of the transverse rod 25 on the lifting rod 23 to change the test effect.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
