[0021] The utility model provides a hardness testing device for polarized lenses. When the hardness testing device is used to test the hardness of the polarized lenses, the polarized lenses are first placed on a workbench, and then the handle on the lifter is rotated to make the lifter drive the workbench, and the workbench drives the polarized lenses to be tested to move in the direction close to the pressure testing head. When the polarized lenses are behind the pressure testing head, the value on the pressure gauge will change. When personnel need to transfer the polarized lenses to the workbench with the help of a push plate, the adjustment ring is first rotated to drive the rubber pad to separate from the fixing seat, and then the connecting plate is rotated to rotate along the inner wall of the fixing seat, and the connecting plate drives the connecting plate. When the connecting plate and the workbench are kept flush with each other, the adjustment ring is rotated to drive the rubber pad to abut against the fixing seat, and then the testing lens is put on the workbench. The polarized lens to be tested is placed on the upper surface of the connecting plate so that one side of the polarized lens fits with the push plate, and then the pull ring is moved to drive the push plate so that the push plate moves the polarized lens on the connecting plate onto the workbench, and finally the pull ring is released. At this time, the spring can drive the push plate to move quickly in the direction away from the support seat, so that the push plate can return to its original position, thereby improving the convenience of using the push plate. Among them, the rubber pad can increase the friction force of the adjustment ring close to the fixed seat, so that the adjustment ring can be squeezed and connected firmly with the fixed seat with the help of the rubber pad. By setting the adjustment structure, personnel can easily transfer the polarized lens to be tested to the narrow space on the workbench, thereby improving the feeding speed of the polarized lens and improving the convenience of using the hardness testing device.

[0022] When the protective cover needs to be disassembled, the protective cover is moved away from the arc track to separate the iron sheet on the lower surface of the protective cover from the magnetic sheet inside the arc track. When the protective cover is separated from the arc track, the protective cover is disassembled. When the personnel finish cleaning the protective cover or the upper surface of the workbench, the protective cover is moved and placed into the arc track until the iron sheet and the magnetic sheet are adsorbed, and the installation of the protective cover is completed. When installing the protective cover, the positioning rod fixed on the protective cover can be inserted into the positioning plate first, so as to achieve the effect of quickly positioning the protective cover. Among them, by setting the protective cover as an acrylic cover, the personnel can see the pressure detection process of the polarized lens on the workbench through the protective cover, thereby improving the practicality of the protective cover. By setting an auxiliary structure, the protective cover can block most of the sides of the workbench, thereby minimizing the occurrence of fragments when the polarized lens is crushed, thereby improving the safety of the device. When the protective cover is worn or the workbench needs to be cleaned, the personnel can easily disassemble and replace the protective cover. BRIEF DESCRIPTION OF THE DRAWINGS

By providing the adjusting structure 3, personnel can conveniently transfer the polarized light lens to be detected to a narrow space on the workbench 7, improving the feeding speed of the polarized light lens and the usability of this hardness detection device. A spring 311 is sleeved on the arc surface of the limit rod 304. The two ends of the spring 311 are respectively fixedly connected to the limit rod 304 and the ear plate 305.

[0033] The working principle of a hardness detection device for polarized lenses provided by the present utility model is as follows: When it is necessary to use the hardness detection device to detect the hardness of a polarized lens, first place the polarized lens on the workbench 7, and then rotate the grip on the lifter 6 to make the lifter 6 drive the workbench 7, and the workbench 7 drives the polarized lens to be detected to move towards the pressure detection head 8. When the polarized lens contacts the pressure detection head 8, the value on the pressure gauge 5 will change. When personnel need to transfer the polarized lens to the workbench 7 with the help of the push plate 306, first rotate the adjusting ring 309 to drive the rubber pad 310 to separate from the fixed seat 301, and then rotate the connecting plate 302 to rotate along the inner wall of the fixed seat 301. The connecting plate 302 drives the connecting plate 303.

When the protective cover 44 is separated from the arc track 41, the protective cover 44 can be disassembled. When the personnel finish cleaning the protective cover 44 or the upper surface of the workbench 7, the protective cover 44 is moved and placed into the arc track 41 until the iron sheet 43 and the magnetic sheet 42 are adsorbed, and the installation of the protective cover 44 is completed. When installing the protective cover 44, the positioning rod 46 fixed on the protective cover 44 can be inserted into the positioning plate 45. , achieving the effect of being able to quickly position the protective cover 44, wherein, by setting the protective cover 44 as an acrylic cover, personnel can see the pressure detection process of the polarized lens on the workbench 7 through the protective cover 44, thereby improving the practicality of the protective cover 44, and by setting the auxiliary structure 4, the protective cover 44 can block most of the sides of the workbench 7, thereby trying to avoid the occurrence of fragments collapsing when the polarized lens is crushed, thereby improving the safety of the device, and when the protective cover 44 is worn or the workbench 7 needs to be cleaned, personnel can easily disassemble and replace the protective cover 44.
