[0015] Further preferably, base plates are fixedly mounted on both left and right sides of the support frame, and anchor bolts are threadedly connected to both front and rear sides of the tops of the two base plates.

[0016] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0017] 1. The utility model sets a lifting mechanism, and through the output of the first motor, the connecting shaft drives the drum to rotate. At this time, the rope is gradually shortened due to the winding of the drum, and the lifting ring is pulled upward to move. With the movement of the lifting ring, the box and the clamping mechanism synchronously drive the lens to move upward, and through the cooperation of the height measuring scale plate and the pointer, it is convenient to understand the height of the lens rise, which saves the operator from the step of moving the lens to a high place by himself, saves a certain amount of labor cost, and improves the convenience of testing. By setting the clamping mechanism, the active bevel gear rotates through the output of the second motor, and through the mutual cooperation with the driven bevel gear, the driven bevel gear drives the installation shaft and the special-shaped plate to rotate. With the movement of the special-shaped plate The connecting plate is turned over and pushed to move inwardly. At this time, the moving block drives the clamping plate to move inwardly synchronously and clamps the lens. When the lens rises to the height required for testing, the second motor drives the active bevel gear to rotate in the opposite direction. At this time, the driven bevel gear, the mounting shaft and the special-shaped plate rotate in the opposite direction synchronously. The connecting plate is turned over again due to the rotation of the special-shaped plate, and pushes the connecting block, the moving block and the clamping plate to move outwardly. At this time, the clamping plate releases the clamping work on the lens, allowing the lens to fall freely due to the influence of gravity, thereby realizing the testing of the lens, saving the step of manually holding the lens, reducing the waste of labor costs, improving the convenience of testing, and having simple operation steps for easy use.

[0018] Second, the utility model can limit the moving direction of the hanging ring by setting the moving plate and the displacement groove, so as to prevent the hanging ring from shaking back and forth and left and right when moving up and down, thereby affecting the testing work of the lens; by setting the limiting groove and the limiting plate, the movement of the connecting block can be limited, so as to prevent the connecting block from shifting in the moving direction due to the flipping of the connecting plate, thereby affecting the clamping work of the lens; by setting the moving groove, the movement of the moving block can be limited, so as to prevent the moving position of the moving block from shifting, resulting in the problem of being unable to clamp the lens; by setting the protective pad, the lens can be protected when the lens is clamped. Avoid excessive clamping force to avoid scratches on the lens surface, which will affect the judgment of the damaged part of the lens surface after the lens drop test. By setting the height measuring scale and pointer, it is convenient to understand the specific height of the lens rise, and convenient for the lens to be dropped at different heights. By setting the box body and concrete slab, the fallen lenses can be collected. At the same time, since the material and hardness of the concrete slab are basically the same as the ground, interference with the detection data can also be avoided. By setting the anchor bolts, the whole equipment can be stabilized to avoid the equipment from tipping over due to collision with external factors, resulting in damage to parts in the equipment.

[0032] A clamping mechanism 3 is provided on the rear side of the box body 5, and the clamping mechanism 3 includes a second motor 301, which is fixedly installed on the rear side of the box body 5, and the output end of the second motor 301 is fixedly connected to the active bevel gear 302 through a rotating shaft, and a mounting shaft 303 is connected to the middle of the bottom of the inner cavity of the box body 5, and a driven bevel gear 304 is fixedly installed on the top of the mounting shaft 303, and the rear side of the driven bevel gear 304 is meshed with the bottom of the active bevel gear 302, and a special-shaped plate 305 is fixedly installed on the middle end of the surface of the mounting shaft 303, and the front and rear sides of the top of the special-shaped plate 305 are movably connected with connecting plates 306, and the bottoms of the two connecting plates 306 are movably connected with connecting blocks 307, and the bottoms of the two connecting blocks 307 are movably connected with moving blocks 308, and the inner sides of the two moving blocks 308 are fixedly installed with clamping plates 309.

[0033] By setting up the lifting mechanism 2, through the output of the first motor 201, the connecting shaft 202 drives the roller 203 to rotate. At this time, the rope 204 is gradually shortened due to the winding of the roller 203, and the lifting ring 205 is pulled upward to move. With the movement of the lifting ring 205, the box 5 and the clamping mechanism 3 synchronously drive the lens to move upward, and through the cooperation of the height measuring scale plate 6 and the pointer 7, it is convenient to understand the height of the lens rising, which saves the operator from the step of moving the lens to a high place by himself, saves a certain amount of labor cost, and improves the convenience of testing.

[0036] By setting the moving plate 207 and the displacement groove 206, the moving direction of the hanging ring 205 can be limited to prevent the hanging ring 205 from shaking back and forth and left and right when moving up and down, thereby affecting the testing work of the lens. By setting the limiting groove 310 and the limiting plate 311, the movement of the connecting block 307 can be limited to prevent the connecting block 307 from being offset in the moving direction due to the flipping of the connecting plate 306, thereby affecting the clamping work of the lens. By setting the moving groove 312, the movement of the moving block 308 can be limited to prevent the moving position of the moving block 308 from being offset, resulting in the problem of being unable to clamp the lens. By setting the protective pad 313, when clamping the lens, , it has a protective effect on the lens, avoids excessive clamping force, leaves scratches on the lens surface, and affects the judgment of the damaged part of the lens surface after the lens drop resistance test. By setting the height measuring scale plate 6 and the pointer 7, it is convenient to understand the specific height of the lens rise, and it is convenient to perform drop resistance tests on the lens at different heights.

[0037] When the utility model is working: first, the active bevel gear 302 rotates through the output of the second motor 301, and through the mutual cooperation with the driven bevel gear 304, the driven bevel gear 304 drives the installation shaft 303 and the special-shaped plate 305 to rotate. With the rotation of the special-shaped plate 305, the connecting plate 306 turns over and pushes the connecting plate 306 to move inward. At this time, the moving block 308 drives the clamping plate 309 to move inward synchronously and clamps the lens. Then, the output end of the first motor 201 drives the connecting shaft 202 to rotate. At this time, the drum 203 rotates synchronously with the connecting shaft 202. The rope 204 is gradually shortened due to the winding of the drum 203, and the lifting ring 205 is pulled upward to move. The moving box 5 of the ring 205 and the clamping mechanism 3 synchronously drive the lens to move upward, and through the cooperation of the height measuring scale plate 6 and the pointer 7, it is convenient to understand the height of the lens rising. When the height to be tested is reached, the second motor 301 drives the active bevel gear 302 to rotate in the opposite direction. At this time, the driven bevel gear 304, the mounting shaft 303 and the special-shaped plate 305 synchronously rotate in the opposite direction. The connecting plate 306 is flipped again due to the rotation of the special-shaped plate 305, and pushes the connecting block 307, the moving block 308 and the clamping plate 309 to move outward. At this time, the clamping plate 309 releases the clamping work on the lens, and the lens falls freely due to the influence of its own gravity and falls on the top of the concrete slab 9, thereby completing the test of the drop resistance of the lens.
