[0019] 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.
[0020] Example: Please see Figure 1 - Figure 6 The eyeglasses with a replaceable lens structure in this embodiment include an eyeglass frame 1 and an external lens 2 placed outside the eyeglass frame 1. An adjustment mechanism is provided between the eyeglass frame 1 and the external lens 2. The adjustment mechanism includes positioning component 3 and support component 3; Positioning component 3 includes a connecting rod 301, an identification block 305, and a limiting head 302; The support components include a plug slot 402 and a limiting slot 403; The limiting head 302 is inserted into the limiting groove 403, and the connecting rod 301 passes through the insertion groove 402; A spring 5 is provided between the external lens 2 and the eyeglass frame 1, and the spring 5 is fixedly set on the outer surface of the eyeglass frame 1; First, the eyeglass frame 1 is in the shape of normal eyeglasses. The external lens 2 is made in proportion to the shape of the eyeglass frame 1. The external lens 2 can be made according to the user's actual needs to meet requirements such as blue light protection and anti-glare. When installing the external lens 2, place it on the outside of the eyeglass frame 1, then push the external lens 2 to one side of the eyeglass frame 1 to compress the spring 5, causing the spring 5 to retract. Then, insert the positioning component 3 into the external lens 2, and insert the connecting rod 301, the limiting head 302 into the insertion groove 402. After inserting the limiting head 302 into the limiting groove 403, rotate the marker block 305 to move it from a vertical state to a horizontal state, so that the limiting groove 403 and the limiting head 302 form a limiting effect. With the spring 5 resetting, push the external lens 2 outward. Thus, under the connection and limitation of the positioning component 3 and the pushing of the spring 5, the external lens 2 is forcibly positioned, which not only ensures the stability of the connection between the eyeglass frame 1 and the external lens 2, but also improves the strength of the connection between the eyeglass frame 1 and the external lens 2, effectively preventing it from falling off during use.
[0021] Please see Figure 5 The outer arc surface of the external mirror 2 has several arc grooves 201 through it. The number of connecting rods 301 and spring pieces 5 is the same, and a part of the outer side of the spring piece 5 passes through the arc grooves 201. First, the spring piece 5 itself is in a certain arc shape, and the length of the arc groove 201 is less than the length of the spring piece 5. This causes the spring piece 5 to move a certain distance into the arc groove 201 when the phase moves. Under the limitation of the length and arc of the spring piece 5 itself, the spring piece 5 and the arc groove 201 are in a limited state, so that it can push the outside of the external mirror 2 and ensure the strength of the limitation of the external mirror 2.
[0022] Please see Figure 5 and Figure 8 The insertion groove 402 is formed on the outer surface of the eyeglass frame 1, and the limiting groove 403 is formed inside the insertion groove 402, and the inside of the limiting groove 403 is a groove of the same specification as the insertion groove 402. By limiting the vertical dimensions of the limiting groove 403 itself, and by setting the dimensions of the limiting head 302 itself to be slightly smaller than those of the limiting groove 403, and by supporting the groove connected within the limiting groove 403, the limiting head 302, when inserted, first moves into the insertion groove 402 and inserts into the limiting groove 403, and then gradually moves into the groove on one side of the limiting groove 403. Thus, when the limiting head 302 is rotated, the limiting head 302 and the limiting groove 403 form a cross-shaped structure. At this time, the limiting head 302 is located inside the limiting groove 403, and the limiting head 302 is limited and moved under the limitation of the dimensions of the limiting groove 403 itself.
[0023] Please see Figure 4 and Figure 5 The external mirror 2 has a guide groove 401 in the middle, and the guide groove 401 passes through the connecting rod 301; The positioning component 3 also includes an auxiliary block 303, a connecting block 304, an marking block 305, a positioning head 306, and a pressing plate 307; The two ends of the connecting rod 301 are fixedly connected to the limiting head 302 and the auxiliary block 303 respectively. The auxiliary block 303 is inserted into the connecting block 304, the marking block 305 is inserted into the connecting block 304, and the pressing plate 307 is inserted into the marking block 305. The positioning head 306 is fixedly installed on the inner side of the pressing plate 307. The positioning head 306 passes through the connecting block 304 and is inserted into the auxiliary block 303. Among them, the auxiliary block 303, the connecting rod 301, and the limiting head 302 are integrated into one piece. The positioning head 306 is simultaneously inserted into the marking block 305, the connecting block 304, and the auxiliary block 303. The marking block 305 is embedded inside the connecting block 304, and the pressing plate 307 is embedded inside the marking block 305. Thus, by pressing the pressing plate 307, the positioning head 306 is simultaneously inserted into the connecting block 304 and the auxiliary block 303, forming the effect of using the marking block 305, the connecting block 304, and the auxiliary block 303 as a whole. Based on the support of multiple limiting rings on the arc-shaped outer side of the positioning head 306, and the limiting rings can be made of materials with certain deformation and friction, such as rubber and soft plastic, when the positioning head 306 is inserted with the auxiliary block 303 and the connecting block 304, the outer limiting ring of the positioning head 306 is compressed and deformed, thus forming a positioning effect. Holes slightly smaller than the outer coil size of the positioning head 306 are made on the connecting block 304 and the auxiliary block 303 to ensure the accuracy of the positioning head 306 when it is inserted and positioned.
[0024] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
