[0002] As an important piece of personal protective equipment, goggles are widely used in industrial, medical, and sports fields, and their core function depends on the protective performance of the lenses. Traditional goggles typically use adhesive or clips to fix the lenses, which has obvious drawbacks: adhesive structures require breaking the original adhesive layer when replacing lenses, which is cumbersome and can easily damage the frame; while clip structures are easy to disassemble, the clips are prone to loosening after long-term use, resulting in the lenses not being securely fixed and affecting the protective effect. Publication number CN213047645U discloses a pair of goggles with easily replaceable lenses, including a frame and lenses. The frame has an annular groove, a positioning screw hole, a limiting protrusion, and a buckle. The buckle is equipped with a strap for easy wearing. The lenses fit into the annular groove, and the two side walls of the annular groove are made of rubber material, with the two sides engaging with the edge of the lens. The upper edge of the lens has a positioning hole that matches the positioning screw hole, and the lower edge has a U-shaped limiting groove that matches the limiting protrusion. The inner side of the lens is coated with an anti-fog film made of hydrophilic anti-fog coating. This device facilitates replacement with new lenses, which helps to increase the utilization rate of the frame. Because the two side walls of the annular groove are made of rubber material, the side walls of the annular groove are elastic, making it easy to unfold and further facilitating the removal and replacement of lenses. However, this patent still has the following problems in actual use: The aforementioned devices and traditional lens fixing methods often cause the fastening threads to directly bear shear force. To ensure tightness, disassembly and assembly are inconvenient, and repeated disassembly of bolts can easily cause excessive wear on the threads that bear the load, leading to lens loosening during use. Moreover, screw wear directly affects the product's lifespan.

[0003] A new type of goggles with easily replaceable lenses is proposed to address the problems mentioned above. Utility Model Content

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5 The present invention provides a technical solution: a pair of goggles with easy lens replacement, including a goggle frame 1, with lens straps 101 installed on both sides of the goggle frame 1, and a lens plate 102 installed inside the front of the goggle frame 1; an installation component 2 is provided between the lens plate 102 and the goggle frame 1, the installation component 2 including a stop ring 201 fixed to the inner wall of the goggle frame 1, a first rubber ring 202 fixedly connected to the side of the stop ring 201 near the lens plate 102, and several clearance grooves 203 are provided on both the stop ring 201 and the first rubber ring 202; a clamping ring 205 is attached to the side of the lens plate 102 away from the stop ring 201, and several positioning strips 207 are fixedly connected to the side of the clamping ring 205 near the lens plate 102, with trapezoidal grooves 208 provided on the positioning strips 207; and a second rubber ring 206 is fixedly connected to the side of the clamping ring 205 near the lens plate 102. Among them, the goggle frame 1 has several screws 209 on its external threaded connection, and one end of the screw 209 extending into the goggle frame 1 is fixedly connected to a conical post 210. When installing the lens plate 102, first place the lens plate 102 inside the goggle frame 1 and block it with the stop ring 201. At the same time, the first rubber ring 202 is attached. Then, the clamping ring 205 is inserted into the goggle frame 1, and the second rubber ring 206 is attached to the outside of the lens plate 102. Meanwhile, the positioning strip 207 is inserted into the goggle frame 1 through the cylindrical hole 204 and the clearance groove 203. Finally, rotate the screw 209 so that the conical column 210 is inserted along the inclined surface of the trapezoidal groove 208. With the inclined surface of the conical column 210, the positioning strip 207 pulls the clamping ring 205 to move slightly. Finally, the clamping ring 205 and the stop ring 201 can clamp the lens plate 102. Since the force direction of the screw 209 is perpendicular to the radial direction of the screw 209, the thread of the screw 209 is not easily damaged by force, avoiding the situation where the threaded hole inside the goggle frame 1 is stripped, which affects the service life of the screw 209. The positioning strip 207 passes through the cylindrical hole 204 and the clearance groove 203, and the conical column 210 is inserted into the trapezoidal groove 208. When the conical column 210 and the trapezoidal groove 208 are inserted, the inclined surfaces slide against each other to achieve auxiliary fastening. When they are in a straight fit, they are locked. The straight fit locking avoids the loosening of the screw 209 from directly affecting the stability of the fixation.

[0018] The top of the screw 209 fits into the goggle frame 1; the top of the screw 209 can be embedded into the outside of the goggle frame 1 to ensure the aesthetics of the outside of the goggle frame 1.

[0019] The number of positioning strips 207, cylindrical holes 204 and clearance grooves 203 are the same and they are evenly distributed; this ensures that the edge of the mirror plate 102 is evenly stressed, and avoids the mirror plate 102 from having a reduced service life due to uneven stress.

[0020] The positioning strip 207 is located inside the second rubber ring 206; the second rubber ring 206 and the first rubber ring 202 not only assist in fastening, but also achieve sealing, increasing the waterproof and rainproof function.

[0021] A strap fastening assembly 3 is provided between the goggle frame 1 and the goggle strap 101. The strap fastening assembly 3 includes a clamping block 301. The clamping block 301 is symmetrically and movably connected by bolts 302. The bolts 302 fit against the outer side of the goggle frame 1 and are threadedly fixed to the outer side of the goggle frame 1. The goggle strap 101 is fixedly connected to the outer side of the clamping block 301. By removing the bolts 302, the clamping block 301 and the goggle strap 101 can be disassembled, which assists in the replacement of the goggle strap 101.

[0022] Working principle: Before using these goggles with easily replaceable lenses, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 5 As shown, during installation, the lens plate 102 is first placed inside the goggle frame 1, with the lens plate 102 blocked by the stop ring 201, and one side of the lens plate 102 fitting against the first rubber ring 202. Next, the clamping ring 205 is inserted into the goggle frame 1, causing the second rubber ring 206 to fit against the outer side of the lens plate 102. At this point, the positioning strip 207 passes through the cylindrical hole 204 and the clearance groove 203 and is inserted into the goggle frame 1. Finally, rotate the screw 209. The cone 210, which is fixed at one end of the screw 209 inside the goggle frame 1, is inserted along the inclined surface of the trapezoidal groove 208 on the positioning strip 207. As the cone 210 goes deeper, it works with the inclined surface of the trapezoidal groove 208 to cause the positioning strip 207 to pull the clamping ring 205 to move slightly. Finally, the clamping ring 205 and the stop ring 201 clamp the lens plate 102, completing the installation of the lens plate 102.

[0023] When it is necessary to remove the lens strap 101, the clamp 301 and the lens strap 101 can be removed by removing the bolt 302, which helps to replace the lens strap 101.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
