So that the operator can connect (as shown in figures 1 to 6) and disconnect (as shown in figures 7 to 9) the grip portion 20 to the frame 30 by moving the frame 30 with respect to the grip portion 20 along the extension direction of the first direction X; the lens 40 can be assembled and disassembled by connecting and disassembling the lens frame 30 and the clamping part 20, the operation is convenient, and other tools are not needed, so that a common user can replace the lens 40 by himself.

Fig. 3, 4 and 7 to 9 schematically show one embodiment of the first and second mounting parts 21, 31. Specifically, as shown in fig. 3, 4 and 8, the first mounting portion 21 includes a first positioning post 211 and a first groove portion 212 integrally molded or machined on a surface of the clamping portion 20 facing the lens frame 30. As shown in fig. 3, 4, 7 and 9, the second mounting portion 31 includes a second positioning column 311 and a second groove portion 312 integrally molded or machined on a surface of the lens frame 30 facing the clamping portion 20; the length of the first groove 212 is arranged along the first direction X, and the second positioning column 311 extends along the direction penetrating through the first groove 212 and is arranged to be matched with the first groove 212 at the positions corresponding to the first position 101 and the second position; the first positioning column 211 is disposed to have an extending direction different from that of the second positioning column 311, and the second groove 312 is disposed to allow the first positioning column 211 to move therein when the first groove 212 moves in the extending direction of the first direction X. For example, the second positioning columns 311 are disposed on the upper and lower sides or the left and right sides of the frame 30, and the second groove 312 is disposed on the front side or the rear side of the frame 30; or the second groove 312 is provided on the upper side, lower side, left side or right side of the frame 30, and the second positioning post 311 is provided on the front side or rear side of the frame 30. When the lens frame 30 is located at the second position, the first positioning column 211 is not easy to be separated from the second groove 312, and the second positioning column 311 is not easy to be separated from the first groove 212, so that the clamping portion 20 is not easy to be separated from the lens frame 30, thereby ensuring that the lens 40 can be stably installed between the clamping portion 20 and the lens frame 30. In a preferred embodiment, the first groove 212 is a through groove, so that an operator can grasp the moving position of the second positioning column 311 in real time when moving the lens frame 30 relative to the clamping portion 20, so as to avoid that the lens 40 falls off from between the clamping portion 20 and the lens frame 30 because the operator is not ready after the clamping portion 20 is separated from the lens frame 30. As one example of the second groove 312, the length of the second groove 312 is greater than the length of the first positioning column 211, so that the first positioning column 211 can move in the second groove 312 along the length direction of the second groove 312, and the first positioning column 211 and the second groove 312 are configured such that, when the second positioning column 311 moves from the first position to the second position along the first direction X relative to the first groove 212, the first positioning column 211 can move relative to the second groove 312 along the length direction of the second groove 312 and simultaneously be embedded in the second groove 312, so that when the second positioning column 311 is located at the second position, the first positioning column 211 can be embedded in the second groove 312, so as to ensure that the clamping portion 20 does not fall off the lens frame 30. As an embodiment, the groove depth direction of the second groove 312 is perpendicular to the extending direction of the second positioning pillar 311. In a preferred embodiment, as shown in fig. 2 and 7 to 9, the lens frame 30 is provided with two sets of second positioning columns 311 and second groove parts 312 on the side surfaces where the second positioning columns 311 and the second groove parts 312 are provided, and the first positioning columns 211 and the first groove parts 212 are provided on the positions of the clamping part 20 corresponding to the second positioning columns 311 and the second groove parts 312. Preferably, two sets of second groove portions 312 are arranged along the length direction thereof to increase the stability of the second groove portions 312 in providing guidance to the first positioning posts 211.

In a preferred embodiment, the first groove 212 and the second positioning post 311 are configured to lock the lens frame 30 at the first position 101 and the second position 102, so as to avoid the problem of poor stability of the connection between the clamping portion 20 and the lens frame 30 caused by the lens frame 30 automatically moving from the first position 101 to the second position relative to the clamping portion 20 during the use of the protective glasses. Specifically, as shown in fig. 2 and 9, the first groove 212 and the second positioning column 311 are configured to lock the frame 30 at the first position 101 and the second position 102 by: the part of the clamping part 20 provided with the first groove part 212 or the second positioning column 311 is made of elastic material; the groove widths of the first groove portion 212 between the first position 101 and the second position 102 are set to fit the second positioning post 311, and the groove width of the first groove portion 212 between the first position 101 and the second position 102 is set to be smaller than the diameter of the second positioning post 311. For example, the elastic material may be SBS, SIS, SEBS, EPDM, POE, TPE, TPV, TPO, TPU, TPEE, PPE, or the like. When the lens frame 30 reciprocates between the first position 101 and the second position 102, the first groove 212 or the second positioning post 311 needs to be elastically deformed to a certain extent by overcoming a certain resistance. In view of the requirement that the frame 30 has sufficient strength and the efficiency of processing the frame 30, it is preferable that the clamping portion 20 be made of an elastic material.

In a preferred embodiment, referring to fig. 5 to 9, the quick-release structure of the safety glasses lens 40 further includes a third positioning column 32 integrally formed, machined or connected to the front side of the frame 30 and a positioning hole 41 integrally formed or machined on the lens 40 and adapted to the third positioning column 32.

For example, the antiskid unit 22 may be implemented as a dot-shaped or strip-shaped protrusion or a groove, and when the antiskid unit 22 is a strip-shaped protrusion, the length direction of the strip-shaped protrusion is different from the length direction of the first groove portion 212 in order to facilitate the force application by the operator. Therefore, when a user intends to push the clamping portion 20 relative to the frame 30 along the extending direction of the first direction X to connect or disconnect the clamping portion and the frame 30, the friction between the user and the surface of the clamping portion 20 can be increased by the anti-slip unit 22, so that the operator can push the clamping portion 20 relative to the frame 30. When two sets of the second positioning columns 311 are also provided, the two corresponding sets of the first groove portions 212 are respectively located at two sides of the anti-slip unit 22, so that when an operator applies force to the anti-slip unit to move the clamping portion 20 relative to the lens frame 30, reaction force of the two second positioning columns 311 to the first groove portions 212 can be uniformly applied to the clamping portion 20, and the clamping portion 20 can be ensured to stably move relative to the lens frame 30.

In a preferred embodiment, as shown with reference to fig. 3 to 6, the safety glasses further comprise a sealing ring 50, said sealing ring 50 being applied between the outer surface of said frame 30 and the inner surface of the lens 40, i.e. the inner surface of the lens 40 is applied against the outer surface of the frame 30 by means of the sealing ring 50. Generally, the sealing ring 50 is made of an elastic material, and the elastic material can be the materials listed above, and will not be described herein. This can avoid the problem that the lens 40 is broken or deformed due to the hard contact between the lens 40 and the rim 30 when the lens 40 is clamped by the clamping portion 20. Preferably, referring to fig. 7 and 9, the cross section of the third positioning pillar 32 is configured to be non-circular, and the length direction of the cross section of the third positioning pillar 32 is parallel to the contour of the sealing ring 50. Therefore, while the strength of the third positioning column 32 is ensured, the influence on the installation space of the sealing ring 50 caused by the overlarge diameter of the third positioning column 32 is avoided.

In a preferred embodiment, as shown in fig. 1, 2, 7-10, the safety eyewear further includes a nose piece 60, the nose piece 60 being removably attached to the frame 30 and clamping the lens 40 therebetween to further secure the stability of the lens 40 when mounted to the frame 30. Illustratively, the nose pad 60 may be made of the aforementioned resilient material. Thereby, the wearing comfort of the user can be increased by the nose pad 60.
