Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of glasses testing equipment and relates to a glasses temple folding testing device. Background Art
[0002] Frame glasses are a common daily necessity used for vision correction or as decoration. The temples of frame glasses need to be unfolded when worn and folded when taken off. That is, the temples of frame glasses need to be folded repeatedly during use. Therefore, before frame glasses are put on the market, fatigue tests need to be carried out on the hinges of the temples to prevent unqualified frame glasses from entering the market. At present, fatigue tests mainly rely on workers to manually fold the temples of the glasses. Manual folding and unfolding of the temples is required until the hinges are damaged, which is time-consuming and labor-intensive. Summary of the Invention
[0003] The purpose of the present invention is to solve the above problems in the existing technology and propose a folding test device for glasses. The technical problem to be solved by the present invention is how to improve the efficiency of fatigue testing of the hinges of the glasses.
[0004] The purpose of this utility model can be achieved through the following technical solutions:
[0005] A glasses temple folding test device includes a frame, characterized in that the frame is provided with a frame fixing seat and a temple clamping assembly, the frame fixing seat is provided with two parallel guide shafts, each guide shaft is sleeved with two vertically arranged frame clamps, the two frame clamps have a plurality of clamping grooves on the opposite surfaces, and the plurality of clamping grooves on the two frame clamps are arranged one by one opposite to each other, the temple clamping assemblies have two and are rotatably arranged on the frame, and the two temple clamping assemblies are respectively located above the two guide shafts.
[0006] The two frame clamps on each guide shaft of the glasses leg folding test device can respectively clamp and fix the two mirror rings of the test glasses frame. At the same time, the frame clamps can move along the length direction of the guide shaft, so that the two frame clamps on the same guide shaft can clamp the mirror rings of the test glasses frames of different sizes. The two temple clamping assemblies located above the two guide shafts can respectively clamp the two temples of the test glasses. During the test, the two temple clamping assemblies respectively drive the two temples of the test glasses to fold or unfold back and forth synchronously in opposite directions until the temple hinges are damaged. This makes the glasses leg folding test device capable of performing temple folding tests on glasses of different sizes. It has good versatility and is simple and convenient to use, thereby simulating manual repeated folding and unfolding of temples, thereby greatly improving the efficiency of temple hinge fatigue testing.
[0007] In the above-mentioned eyeglass temple folding test device, the thickness of the bottom of the frame clamp is greater than the thickness of the top, and the bottom of the frame clamp is sleeved on the guide shaft. A transversely arranged locking bolt is threadedly connected to the frame clamp, and the locking bolt can abut against the surface of the guide shaft. This allows the spacing between the two frame clamps on the same guide shaft to be adjusted, and after the adjustment is in place, the locking bolt is rotated so that the locking bolt abuts against the surface of the guide shaft, eliminating the moving gap between the frame clamp and the guide shaft, thereby locking the frame clamp on the guide shaft, allowing the two frame clamps on the same guide shaft to better clamp one of the lens rings of test glasses frames of different sizes, thereby making the eyeglass temple folding test device adaptable to glasses of different sizes and having good versatility.
[0008] In the aforementioned eyeglass temple folding test device, the temple clamping assembly includes a motor mounted on a frame, a fixed block mounted on the motor's output shaft, and a clamping claw mounted on the fixed block for clamping the temple. The motor drives the clamping claw on the fixed block to rotate, thereby better simulating the repeated manual folding and unfolding of the temple and improving the efficiency of the temple hinge fatigue test.
[0009] In the aforementioned eyeglass temple folding test device, the frame is provided with two positioning posts located outside the fixed block, the two positioning posts being located on the same circumference. A limiting post is provided on the fixed block, located between the two positioning posts and capable of abutting against each of the two positioning posts. The coordinated structure of the limiting post and the two positioning posts allows for more precise folding and unfolding angles of the tested glasses, preventing damage to the temple hinges due to over-folding or over-expansion, thereby improving the accuracy of temple hinge fatigue testing.
[0010] In the aforementioned eyeglass temple folding test device, the frame is provided with two arcuate grooves on the outer side of the fixing block. The two arcuate grooves are located on the same circumference, and the two positioning posts are respectively inserted into the two arcuate grooves. If the test glasses vary in size, the positioning posts can be inserted into different positions of the arcuate grooves, thereby better achieving the folding and unfolding of the test glasses' temples.
[0011] In the aforementioned eyeglass temple folding test device, the frame is further provided with angle scale lines, and the positioning block is provided with a pointer for pointing to the angle scale lines. This not only makes the folding and unfolding angles of the temples more intuitive, but also facilitates better adjustment of the positioning post when testing glasses of varying sizes.
[0012] Compared with the existing technology, the advantages of this glasses temple folding test device are: this glasses temple folding test device can perform temple folding tests on glasses of different sizes, has good versatility, and is simple and convenient to use, thereby greatly improving the efficiency of temple hinge fatigue testing.
