Description

The present invention deals with the field of protective articles, in particular protective eyewear for machining.

When a person performs machining, the processing equipment operates at high speed to cause cutting debris to interlock and eject at high speed, which easily damages the operator's eyes and cleans the conventional eyeglasses after cutting coolant has been attached to them. It is difficult to wipe, and if the conventional protective glasses are directly placed on the table surface, the lenses are easily damaged, so that protective glasses for machining are required to solve the above problems.

In the following, the applicant introduces the method of use in detail with reference to FIGS. 1 to 4 and the specific configuration of the above-mentioned protective glasses for machining of the present application:

The protective glasses are placed on the front side of the eyes and at the same time, the fixing block 28 is placed on the rear side of the head of the user, and at this time, the second motor 49 is started and rotated to interlock the worm 50 to rotate. This causes the worm wheel 51 to rotate in an interlocking manner, which in turn causes the second reel 25 to interlock and rotate, thereby winding the second drawstring 23 around the outer surface of the second reel 25. At this time, the second drawstring 23 fixes the protective glasses to the front side of the eyes, and at this time, the second motor 49 continuously rotates to interlock the second drawstring 23 and the first rack 34. To move downward, thereby interlocking the second rack 36 to move upward, thereby interlocking the slide block 42 to move upward, and thereby interlocking the first gear 45. When the lens is wiped and the lens is wiped, the first motor 43 is started and rotated, which causes the first gear 45 to rotate in an interlocking manner, which causes the third gear 46 to interlock. The screw thread rod 30 is interlocked and rotated, and the thread rod 30 is rotated to interlock and move the concave block 11, thereby interlocking the cleaning cloth 12. After the lens 13 has been wiped and the equipment has been used, the second motor 49 is started to rotate in the opposite direction, at which time the second drawstring 23 is loosened and the first rack 34 is It returns under the action of the returning device 33, which interlocks the slide block 42 to move downward, thereby interlocking the first gear 45 with the second gear 41, and at this time, The first motor 43 is started and rotated, and thereby the first reel 31 is interlocked and rotated, whereby the first pulling string 32 is released, and at this time, the two left and right eyeglass frames 10 are Under the action of the spring 19, the lenses 13 face each other and rotate and come into close contact with each other. At this time, the lens 13 is wrapped in the spectacle frame 10 to thereby protect the lens 13.

From the above detailed analysis, the protective spectacles of the present invention can be conveniently fixed to the head, and at the same time, the lens of the spectacles is equipped with a wiping device, which is convenient for wiping when the lens becomes oily and the equipment is It can be seen that it can be automatically folded when not in use, wrapping the lens and providing protection to the lens.
