Technical Field

[0001] The utility model relates to the technical field of protective glasses, and particularly relates to a pair of protective glasses. Background Art

[0002] Protective glasses are an important part of personal protective equipment. According to their usage functions, they can be divided into ordinary protective glasses and special protective glasses. Protective glasses are a special type of glasses, which are designed to prevent radioactive, chemical, mechanical, and light damage of different wavelengths. There are many types of protective glasses, and different glasses are required for different occasions and different needs. Commonly, there are various types such as dust-proof glasses, impact-proof glasses, chemical-proof glasses, and light-radiation-proof glasses.

[0003] Chinese Patent with application publication number CN105527722A discloses a pair of protective glasses. The invention has a simple and reasonable structure, is economical and practical, and is convenient to use. Through the cooperative use of an elastic headband, the wearing is convenient and firm, and it is not easy to fall off. By arranging dense through holes on the rubber spectacle frame, the protective glasses have good air permeability, which is beneficial to the health of the eyes.

[0004] In order to solve the problems of insecure wearing and easy falling off in the above technical solution, the prior art adopts the method of cooperative use of an elastic headband for treatment, but there will still be a situation where the lens is inconvenient to disassemble, which further leads to the problem of difficult lens replacement. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a pair of protective glasses to solve the problems put forward in the above background art.

[0006] To solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A pair of protective glasses includes a lens mechanism. A spectacle frame mechanism is fixedly connected to the tail end of the lens mechanism, and an adjusting mechanism is fixedly connected to one side of the spectacle frame mechanism.

[0008] The lens mechanism includes a return spring. A clamping block is fixedly connected to the top end of the return spring. A dial is fixedly connected to the back of the clamping block. A lens is sleeved inside the clamping block.

[0009] A further improvement of the technical solution of the utility model lies in that: the spectacle frame mechanism includes a spectacle frame, which is fixedly connected to the tail end of the return spring. The spectacle frame is sleeved with the clamping block, the dial, and the lens. A soft pad is fixedly connected to the inner side of the spectacle frame, and an anti-slip pad is fixedly connected to the inner side of the soft pad. The soft pad can protect the wearer's nose bridge, and the anti-slip pad can increase the friction between the soft pad and the wearer's face, avoiding the protective glasses from falling off during wearing, thereby achieving the purpose of improving the practicability of the protective glasses.

[0010] A further improvement of the technical solution of the utility model is that a rubber pad is fixedly connected to the top of the glasses frame, and a connecting buckle 1 and a connecting buckle 2 are fixedly connected to the rear end of the glasses frame. The rubber pad fills the gap between the top of the glasses frame and the wearer's face to prevent harmful objects from falling from the gap, thereby achieving the purpose of improving the practicality of the protective glasses.

[0011] A further improvement of the technical solution of the utility model is that: the adjustment mechanism includes a buckle 1, the buckle 1 is buckled with a connecting buckle 1, the tail end of the buckle 1 is rotatably connected with a fixed buckle 1, and by pressing one side of the buckle 1, the buckle 1 can be connected to the connecting port 1, thereby achieving the purpose of easy installation and disassembly.

[0012] A further improvement of the technical solution of the utility model is that an adjustment rope is fixedly connected to the surface of the fixing buckle, an adjustment buckle is inserted into the surface of the adjustment rope, the tail end of the adjustment rope is fixedly connected to the middle part of the adjustment buckle, and the position of the adjustment buckle is adjusted, so that the folding degree of the adjustment rope can be adjusted, thereby achieving the effect of adjusting the circumference of the head of the protective glasses.

[0013] A further improvement of the technical solution of the utility model is that: a fixing buckle 2 is sleeved on the surface of the adjusting rope, a buckle 2 is rotatably connected to the front side of the fixing buckle 2, a U-shaped limit block is fixedly connected to the inside of the buckle 2, the U-shaped limit block is fixedly connected to the inner side of the buckle 1, and the side on which the buckles 1 and 2 can be pressed is located between the U-shaped limit blocks, thereby avoiding the problem of left and right shaking of the side on which the buckles 1 and 2 can be pressed, thereby achieving the purpose of improving the stability of the buckles 1 and 2.

[0014] A further improvement of the technical solution of the utility model is that the second buckle is clamped inside the connecting buckle one, the second fixing buckle is parallel to the connecting buckle one, and the fixing buckle one is parallel to the connecting buckle two, and the second buckle can connect the connecting buckle one and the fixing buckle two, thereby facilitating disassembly and installation.

[0015] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0016] 1. The utility model provides a pair of protective glasses. By pushing a paddle inside a glasses frame to both sides, a clamping block can be driven to move to both sides, thereby releasing the arc-shaped blocks on both sides of the lens from the grooves in the clamping block. The lens loses the supporting force on both sides and can fall out of the glasses frame. Then, a new lens is pushed to the inside of the glasses frame, so that the arc-shaped clamping blocks on both sides of the lens enter the inside of the clamping block, and the lens can be fixed inside the glasses frame, thereby solving the problem that it is difficult to replace the lens.

[0017] 2. The present utility model provides a pair of protective glasses. Fix the adjustment buckle with one hand and pull the adjustment rope on one side of the fixing buckle two with the other hand, thereby changing the position of the adjustment buckle on the adjustment rope. When the adjustment buckle is closer to the fixing buckle one, the folding degree of the adjustment rope is higher, so that the head circumference of the protective glasses is smaller. When the adjustment buckle is closer to the fixing buckle two, the head circumference is larger, which can be suitable for wearers with different head circumferences, thus achieving the purpose of expanding the applicable range.

[0023] The following further describes the present utility model in detail with reference to the embodiments:

[0024] Embodiment 1

[0025] As Figures 1-4 shown, the present utility model provides a pair of protective glasses, including a lens mechanism 1. The tail end of the lens mechanism 1 is fixedly connected to a frame mechanism 2. One side of the frame mechanism 2 is fixedly connected to an adjustment mechanism 3. The lens mechanism 1 includes a return spring 11. The top end of the return spring 11 is fixedly connected to a block 12. The back of the block 12 is fixedly connected to a paddle 13. A lens 14 is sleeved inside the block 12;

[0026] Specifically, when the lens 14 needs to be replaced, the paddle 13 inside the spectacle frame 21 is toggled to both sides, which can drive the clamping block 12 to move to both sides, thereby releasing the arc-shaped blocks on both sides of the lens 14 from the grooves in the clamping block 12. Then, the outer side of the lens 14 is faced towards the tabletop. Without the support force on both sides, the lens 14 will fall out of the spectacle frame 21. Then, the new lens 14 is pushed towards the inside of the spectacle frame 21, so that the arc-shaped clamping blocks on both sides of the lens 14 enter the inside of the clamping block 12, and the lens 14 can be fixed inside the spectacle frame 21.

[0027] Embodiment 2

[0028] As Figures 1-4 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the spectacle frame mechanism 2 includes a spectacle frame 21, and the spectacle frame 21 is fixedly connected to the tail end of the return spring 11. The spectacle frame 21 is sleeved with the clamping block 12, the paddle 13 and the lens 14. A soft pad 22 is fixedly connected to the inner side of the spectacle frame 21, and an anti-slip pad 23 is fixedly connected to the inner side of the soft pad 22. A rubber pad 24 is fixedly connected to the top end of the spectacle frame 21, and a connecting buckle one 25 and a connecting buckle two 26 are fixedly connected to the tail end of the spectacle frame 21;

[0029] Specifically, a soft pad 22 and an anti-slip pad 23 are provided at the joint between the spectacle frame 21 and the nose bridge, which can improve the fitting degree between the spectacle frame 21 and the nose bridge and the comfort of the wearer, thereby avoiding the situation of hurting the wearer's nose bridge due to long-term wearing. When wearing the protective glasses, the arc-shaped support plates on both sides of the spectacle frame 21 are placed on the ears to support the spectacle frame 21.

[0030] Embodiment 3

[0031] As Figures 1-4 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the adjusting mechanism 3 includes a buckle one 31, and the buckle one 31 is clamped with the connecting buckle one 25. The tail end of the buckle one 31 is rotatably connected to a fixing buckle one 32. A adjusting rope 33 is fixedly connected to the surface of the fixing buckle one 32. An adjusting buckle 37 is inserted through the surface of the adjusting rope 33. The tail end of the adjusting rope 33 is fixedly connected to the middle of the adjusting buckle 37. A fixing buckle two 34 is sleeved on the surface of the adjusting rope 33. A buckle two 35 is rotatably connected to the front side of the fixing buckle two 34. A U-shaped limiting block 36 is fixedly connected to the inside of the buckle two 35. The U-shaped limiting block 36 is fixedly connected to the inside of the buckle one 31. The buckle two 35 is clamped inside the connecting buckle one 25. The fixing buckle two 34 is parallel to the connecting buckle one 25, and the fixing buckle one 32 is parallel to the connecting buckle two 26;

[0032] Specifically, place the arc-shaped support plates on both sides of the spectacle frame 21 on the ears, and then the wearer adjusts the length of the adjustment rope 33 according to their own head circumference. When adjusting, fix the adjustment buckle 37 with one hand and pull the adjustment rope 33 on one side of the second fixed buckle 34 with the other hand, so as to change the position of the adjustment buckle 37 on the adjustment rope 33. When the adjustment buckle 37 is closer to the first fixed buckle 32, the folding degree of the adjustment rope 33 is higher, so that the head circumference of the protective glasses is smaller. When the adjustment buckle 37 is closer to the second fixed buckle 34, the head circumference is larger. Thus, adjusting the adjustment rope 33 can be suitable for wearers with different head circumferences, and accordingly avoid the situation that the protective glasses fall off when the wearer uses them.

[0033] Next, the working principle of the protective glasses will be specifically described.

[0034] As Figures 1-4 shown, place the arc-shaped support plates on both sides of the spectacle frame 21 on the ears, so that the anti-slip pads 23 are in contact with the bridge of the nose. Then the wearer adjusts the length of the adjustment rope 33 according to their own head circumference. When adjusting, fix the adjustment buckle 37 with one hand and pull the adjustment rope 33 on one side of the second fixed buckle 34 with the other hand, so as to change the position of the adjustment buckle 37 on the adjustment rope 33 to improve the fitting degree between the protective glasses and the wearer's face.

[0035] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements that do not depart from the spirit of the present invention are all within the protection scope of the present invention.
