[0026] In an embodiment of the present utility model, a staff member starts the detection head 6 through the control console 2, places the optical lens whose thickness is to be measured in the detection table 5, emits a laser through the detection head 6, and projects the laser through the lens into the workbench 3. The workbench 3 transmits the measured information to the control console 2, so that the control console 2 displays the measured thickness of the optical lens on the screen.

[0027] Figures 1 to 5As shown, a first sealing cover 14 is provided at the top of the console 2, a first spring 13 is connected to the top of the first sealing cover 14, a circular plate 12 is fixedly installed on the top of the first spring 13, a second spring 18 is connected to the top of the circular plate 12, a second sealing cover 19 is fixedly installed on the top of the second spring 18, a circular shell 7 is fixedly installed on one side of the workbench 3, a movable rod 8 is movably installed on the inner side of the circular shell 7, a support plate 9 is fixedly installed on the top of the movable rod 8, the circular shell 7 and the support plate 9 are connected by a torsion spring 10, and the torsion spring 10 is located on the outside of the movable rod 8, A circular ring 11 is fixedly installed on one side of the support plate 9, and the inner wall of the circular ring 11 is fixed to the circular plate 12. Two first limiting shells 15 are symmetrically fixedly installed on the top of the first sealing cover 14, and two second limiting shells 20 are symmetrically fixedly installed on both sides of the second sealing cover 19, and each second limiting shell 20 is located on the top of the first limiting shell 15 at the corresponding position. A threaded plate 16 is fixedly installed on the top of the first sealing cover 14, and a positioning bolt 17 is threadedly installed inside the threaded plate 16. A side plate 21 is fixedly installed on one side of the second sealing cover 19, and a circular hole is opened inside the side plate 21.

[0028] In the embodiment of the present invention, when the detection head 6 and the detection table 5 need to be placed, the staff rotates the support plate 9 180 degrees counterclockwise, so that the support plate 9 rotates around the movable rod 8 under the support of the torsion spring 10, so that the first sealing cover 14 moves to the top of the detection table 5, and the first sealing cover 14 can drive the first limiting shell 15 to move upward under the action of external force, and the second sealing cover 19 moves to the bottom of the detection head 6. The second sealing cover 19 can drive the second limiting shell 20 to move downward under the action of external force, and screw the positioning bolt 17 so that the positioning bolt 17 is fixed on the threaded plate 1. 6, and unscrew the positioning bolt 17 out of the circular hole of the side plate 21, so that the positioning bolt 17 no longer fixes the threaded plate 16 and the side plate 21, so that the first spring 13 uses its own elastic force to drive the first sealing cover 14 to move downward under the fixed support of the circular plate 12, and the second spring 18 uses its own elastic force to drive the second sealing cover 19 to move upward under the fixed support of the circular plate 12, so that the first sealing cover 14 wraps the detection table 5, and the second sealing cover 19 wraps the detection head 6, thereby preventing dust and impurities in the air from adhering to the detection table 5 and the detection head 6.

[0029] Figures 1 to 5As shown, a fastening bolt 22 is threadedly installed on the top of the support plate 9, and a sleeve 23 is movably installed on the outside of the fastening bolt 22, and the sleeve 23 is located at the top of the support plate 9, and a telescopic plate 24 is movably installed on the inside of the sleeve 23, and the bottom of the telescopic plate 24 is connected to a third spring 25, and the end of a support rod 26 is fixedly installed on the bottom of the third spring 25, and the third spring 25 is located on the outside of the support rod 26, and a suction cup 27 is fixedly installed on the bottom of the support rod 26, and a bracket 28 is fixedly installed on one side of the round shell 7, and a round cover 29 is fixedly installed on the top of the bracket 28, and the round cover 29 fits the bottom of the suction cup 27.

[0030] In the embodiment of the present utility model, the support rod 26 is pulled upward to drive the suction cup 27 to move away from the round cover 29, and the fastening bolt 22 is twisted so that the fastening bolt 22 moves upward under the threaded support of the outer sleeve 23, so that the fastening bolt 22 no longer cooperates with the support plate 9 to clamp and fix the outer sleeve 23. The outer sleeve 23 is rotated clockwise so that the outer sleeve 23 drives the suction cup 27 to rotate around the fastening bolt 22 through the support rod 26. At the same time, the telescopic plate 24 is moved out of the inner side of the outer sleeve 23, so that the suction cup 27 is moved to the top of the lens to be tested, and the support rod 26 is loosened, so that the third spring 25 uses its own elastic force to drive the suction cup 27 to press downward through the support rod 26, so that the suction cup 27 adsorbs the lens, and the lens is easily moved out of the testing table 5 through the suction cup 27, thereby providing convenience for the staff.

[0031] Working principle: while the staff moves the positioning bolt 17 upwards, presses the side plate 21 downwards, so that the positioning bolt 17 drives the first sealing cover 14 away from the detection table 5 through the threaded plate 16, and the side plate 21 drives the second sealing cover 19 to move away from the detection head 6. By screwing the positioning bolt 17 into the circular hole of the side plate 21, the first sealing cover 14 and the second sealing cover 19 are fixed, and the support plate 9 is loosened, so that the torsion spring 10 uses its own elastic force to drive the first sealing cover 14 and the second sealing cover 19 to reset, and starts the detection head 6 through the console 2, and places the optical lens to be measured in thickness in the detection table 5. The laser is emitted by the detection head 6, so that the laser passes through the lens and projects light into the workbench 3, and the workbench 3 transmits the measured information to the console 2, so that the console 2 displays the measured thickness of the optical lens on the screen, and drives the suction cup 27 to move away from the round cover 29 by pulling the support rod 26 upwards, and screws the fastening bolt 22, so that the fastening bolt 22 moves upward under the threaded support of the outer sleeve 23. The fastening bolt 22 no longer cooperates with the support plate 9 to clamp the outer sleeve 23. The outer sleeve 23 is rotated clockwise, so that the outer sleeve 23 drives the suction cup 27 to rotate around the fastening bolt 22 through the support rod 26. At the same time, the telescopic plate 24 is moved out of the inner side of the outer sleeve 23. At the same time, the telescopic plate 24 is pulled to move the suction cup 27 to the top of the lens to be tested. The support rod 26 is loosened, so that the third spring 25 uses its own elastic force to drive the suction cup 27 to press downward through the support rod 26, so that the suction cup 27 adsorbs the lens. The suction cup 27 facilitates the removal of the lens from the detection table 5. When the detection head 6 and the detection table 5 need to be placed, the staff rotates the support plate 9 180° counterclockwise so that the support plate 9 rotates around the movable rod 8, moves the first sealing cover 14 to the top of the detection table 5, and moves the second sealing cover 19 to the bottom of the detection head 6. Unscrew the positioning bolt 17 out of the circular hole of the side plate 21, so that the first sealing cover 14 wraps the detection table 5, and the second sealing cover 19 wraps the detection head 6.

[0032] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
