[0025] The present invention will be described in further detail below with reference to the accompanying drawings.

[0026] As shown in Figures 1-7, this embodiment discloses a pair of protective glasses, including a frame 1 and a pair of temples 2 hinged on the frame 1, each temple 2 has a protective cover 3, and the protective cover 3 is provided with two spaced-apart fasteners 4, a pair of the fasteners 4 each includes an elastically deformable connecting rod 41, and a pair of the connecting rods 41 are provided with mutually symmetrical conical heads 42 at the ends; when a pair of connecting rods 41 are inserted into the clamping holes 5, the pair of connecting rods 41 will be squeezed by the inner walls of the clamping holes and compressed and deformed, at this time, the conical heads 42 will abut against the inner walls of the clamping holes; and when the connecting rods 41 are fully inserted, the connecting rods 41 will elastically reset, at this time, the conical heads 42 will be engaged with the clamping holes, thereby realizing the connection between the protective cover 3 and the temple 2; wherein, a pair of spaced-apart fasteners allow the protective cover to be engaged with the temple, and there are more than two support points between the protective cover and the temple, thereby ensuring the stability of the connection and avoiding the problem of shaking after the connection.

[0027] In the prior art, the temples and the protective covers must be fixedly connected to prevent workers from disassembling them at will. Therefore, they are usually fixedly connected by rivets before leaving the factory. Therefore, when workers need to wear and install lenses, the protective covers will affect the installation of the workers. If the temples and the protective covers are simply fixed by a snap-on connection, although it is convenient for customers to disassemble and assemble, it is also convenient for workers to disassemble and assemble, which creates certain safety hazards.

[0028] In the present application, the temple 2 is provided with at least one latch hole 5 for engaging with a pair of fasteners 4; the latch holes 5 can be two or one elongated latch hole 5. If it is an elongated latch hole 5, a pair of fasteners 4 are symmetrically engaged with the two ends of one latch hole (that is, it can be regarded as two latch holes connected to each other in the middle, the structure is relatively simple, and therefore not shown in the accompanying drawings); the latch hole is provided with a protrusion 11, which makes the latch hole have a stepped structure with a small outside and a large inside; the fastener 4 is located in the latch hole 5, and its conical head 42 is engaged with the locking groove; while it is convenient for customers to engage the fastener with the latch hole, it also avoids the fastener from being exposed to the outside, preventing the staff from arbitrarily disassembling the protective cover.

[0029] In this embodiment, the protective cover 3 is provided with a limiting groove 6 that is adapted to the shape and size of the temple 2; through the limiting groove 6, the protective cover 3 can wrap the temple 2 to limit the upward and downward movement between the protective cover 3 and the temple 2; further improving the stability between the protective cover 3 and the temple.

[0030] In this embodiment, a through hole 7 is provided on the protective cover 3, and a positioning block 8 is formed on the temple 2 to be plugged into the through hole 7. The positioning block 8 is used to position the relative position between the card hole 5 and the fastener 4; the setting of the positioning block facilitates the alignment of the fastener and the card hole, and facilitates installation; at the same time, a logo can be set on the surface of the positioning block to make the glasses more beautiful and natural.

[0031] In this embodiment, the protective cover 3 is provided with an arc-shaped rib 9, and an arc-shaped groove that matches the shape and size of the edge of the frame 1 is formed between the rib 9 and the protective cover 3. The edge of the frame 1 is provided with a step surface 10 that matches the shape of the rib 9. When the protective cover 3 is assembled on the temple 2 and the temple 2 is at the maximum opening angle, the inner wall of the arc-shaped groove abuts against the step surface 10 of the edge of the frame 1, allowing the protective cover 3 to wrap the side of the frame 1. At this time, the end face of the rib 9 away from the temple 2 is flush with the end face of the frame 1 away from the temple 2;

[0032] The arc-shaped ribs on the protective cover can abut against the stepped surface of the edge of the frame, which reduces the gap between the protective cover and the frame, improves the protection ability of the protective cover, and makes the frame more beautiful.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention should be included in the scope of protection of the present invention.
