Description

Technical Field

[0001] This application relates to the field of sunglasses technology, and more particularly to a pair of sunglasses equipped with replaceable lenses. Background Technology

[0002] Sunglasses, also known as sun protection glasses, are essential items used in daily life to block sunlight. They are widely used in various outdoor activities. Their core function is to prevent strong light from harming the eyes. In sunlight, the human eye mainly controls the amount of light by adjusting the size of the pupil. When the intensity of external light exceeds the eye's adjustment limit, it can not only cause eye fatigue but may also cause irreversible stimulation or damage to eye tissues such as the retina. Therefore, sunglasses are an essential piece of equipment in the summer when the sunlight is strong and in outdoor environments.

[0003] Currently, most sunglasses on the market consist of two parts: a frame and lenses. The lenses and frames are usually integrated into one piece using a fixed connection method. However, when the lenses are damaged due to accidental collisions or scratches, or when their light transmittance decreases or their surface wears down due to long-term use, users cannot replace the lenses themselves. They must go to a professional optician's shop, where staff will use special tools to disassemble and replace the lenses. This process not only consumes time and travel costs but also interrupts the user's normal use of the sunglasses, causing great inconvenience to daily travel and outdoor activities, and failing to meet users' basic demand for convenient maintenance of sunglasses. Utility Model Content

[0004] In view of the above-mentioned problems existing in the prior art, the main objective of this application is to provide sunglasses equipped with replaceable lenses.

[0005] The technical solution of this application is as follows: a pair of sunglasses equipped with replaceable lenses includes a frame, a support frame fixedly connected to the middle of the frame, a lens body engaged inside the frame, a fixing seat fixedly connected to both ends of one side of the support frame, the lens body abutting against the inner ring, a rotating shaft provided inside the fixing seat, a snap-fit ​​component fixedly connected to the middle of the rotating shaft, and torsion springs sleeved on both sides of the outer periphery of the rotating shaft and located on both sides of the snap-fit ​​component, the rotating shaft being rotatably mounted inside the fixing seat by the torsion springs.

[0006] In a preferred embodiment, four elastic buckles are fixedly connected to the outside of the frame, and each elastic buckle abuts against the edge of the lens body.

[0007] In a preferred embodiment, the inner wall of the frame is fixedly connected to two inner rings, and the lens body abuts against the corresponding inner ring.

[0008] In a preferred embodiment, a rubber pad is fixedly connected to the side of the snap-fit ​​member near the lens body, and the rubber pad is in contact with the lens body.

[0009] In a preferred embodiment, both sides of the frame are fixedly connected to fasteners, and the ends of the fasteners away from the frame are hinged to a temple, with an armrest fitted at the end of the temple.

[0010] In a preferred embodiment, lifting members are fixedly connected to both sides of the snap-fit ​​component, and two nose pads are fixedly installed on the inner wall of the frame.

[0011] Compared with the prior art, the advantages and positive effects of this application are as follows:

[0012] 1. In this application, under normal conditions, the elastic force of the torsion spring can drive the snap-fit ​​to tightly press against the lens body. When replacing, simply pull the lifting parts on both sides of the snap-fit ​​to drive the rotating shaft to compress the torsion spring and detach it from the lens body. The above structure allows users to complete the disassembly of the lens body and the installation of the new lens body in a short time, completely eliminating the dependence on professional stores, saving time and transportation costs, and avoiding the problem of the lens body being unusable due to waiting for replacement, significantly improving the convenience of maintenance.

[0013] 2. In this application, the elastic buckle has deformable characteristics. Users can release the restriction on the lens body by simply pressing it manually without the need for tools. The rubber pad increases the friction with the lens body, further improving the fixing effect, and also prevents the buckle from directly contacting the lens body and causing wear.

[0019] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0020] Reference Figure 1-4 A type of sunglasses equipped with replaceable lenses includes a frame 1, a support frame 2 fixedly connected to the middle of the frame 1, a lens body 3 snapped into the inside of the frame 1, and a fixing seat 7 fixedly connected to both ends of one side of the support frame 2. The lens body 3 abuts against the inner ring 12. A rotating shaft 8 is provided inside the fixing seat 7, and a snap-fit ​​piece 10 is fixedly connected to the middle of the rotating shaft 8. Torsion springs 9 are sleeved on both sides of the outer periphery of the rotating shaft 8 and located on both sides of the snap-fit ​​piece 10. The rotating shaft 8 is rotatably installed inside the fixing seat 7 through the torsion springs 9. Under normal conditions, the elastic force of the torsion springs 9 can drive the snap-fit ​​piece 10 to tightly abut against the lens body 3. When replacing, simply pull the lifting pieces on both sides of the snap-fit ​​piece 10 to drive the rotating shaft 8 to compress the torsion springs 9 and detach it from the lens body 3. The above structure allows users to complete the disassembly of the lens body 3 and the installation of the new lens body 3 in a short time, completely eliminating the dependence on professional stores, saving time and transportation costs, and avoiding the problem of the lens body 3 becoming unusable due to waiting for replacement, significantly improving the convenience of maintenance.

[0021] Specifically, four elastic buckles 5 are fixedly connected to the outer side of the frame 1. The elastic buckles 5 all abut against the edge of the lens body 3. The four elastic buckles 5 fixed to the outer side of the frame 1 directly abut against the edge of the lens body 3. The elastic buckles 5 have deformable characteristics. The user can release the restriction on the lens body 3 by manually pressing without the need for tools. Two inner rings 12 are fixedly connected to the inner wall of the frame 1. The inner rings 12 can form circumferential support for the lens body 3 and limit the lateral displacement of the lens body 3. The lens body 3 abuts against the corresponding inner ring 12. A rubber pad 11 is fixedly connected to the side of the snap fastener 10 near the lens body 3. The rubber pad 11 can increase the friction with the lens body 3, further improve the fixing effect, and avoid the snap fastener 10 directly contacting the lens body 3 and causing wear.

[0022] Specifically, both sides of the frame 1 are fixedly connected to fasteners 4, and the ends of the fasteners 4 away from the frame 1 are hinged to the temples 13, which can flexibly adjust the opening angle according to the user's head size to adapt to different head shapes. The tail end of the temples 13 is fitted with an arm rest 14. Both sides of the snap fasteners 10 are fixedly connected to lifting parts. Two nose pads 6 are fixedly installed on the inner wall of the frame 1, which can conform to the curve of the user's nose bridge, distribute the weight pressure of the frame 1 and the lens body 3, and avoid pressure marks on the nose bridge.

[0023] Working principle: First, under normal conditions, the elastic force of the torsion spring 9 can drive the locking piece 10 to tightly press against the lens body 3, and the four elastic buckles 5 fixed on the outside of the frame 1 directly contact the edge of the lens body 3, which can ensure the stability of the lens body 3 during the user's movement. When replacing, simply pull the lifting pieces on both sides of the locking piece 10 and manually press to release the restriction on the lens body 3, which can drive the rotating shaft 8 to compress the torsion spring 9 and detach it from the lens body 3. The above structure allows users to complete the disassembly of the lens body 3 and the installation of the new lens body 3 in a short time, completely eliminating the dependence on professional stores, saving time and transportation costs, and avoiding the problem of the lens body 3 being unusable due to waiting for replacement.
