DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Referring to Figures 1 to 6 As shown, to achieve the above object, the present invention provides the following technical solution: A pair of sunglasses facilitating lens replacement, including a lens frame 1, temple arms 2 and a lens assembly 3. Connecting parts 11 are symmetrically arranged on the lens frame 1. Mounting blocks 4 are rotatably connected at the connecting parts 11. Two sets of mounting grooves 41 for mounting the lens assembly 3 are symmetrically arranged on the mounting blocks 4. When one mounting groove 41 is in the position to be installed, the other mounting groove 41 is in the using position. An assembly groove 42 communicating with the mounting groove 41 is arranged on the mounting block 4. A fixing rod 5, a linkage rod 51, a linkage spring 52 and a linkage member 53 are arranged in the assembly groove 42. The linkage rod 51 is horizontally slidably connected in the assembly groove 42 through the linkage spring 52. The fixing rod 5 is vertically slidably connected in the assembly groove 42 and is linked with the linkage rod 51 through the linkage member 53. The lens assembly 3 is provided with a fixing hole for inserting the fixing rod 5. A rotation limiting hole 43 and a linkage hole 44 are arranged on one side of the mounting block 4. The rotation limiting hole 43 is communicated with the mounting groove 41. The linkage hole 44 is communicated with the assembly groove 42. A control plate 12 and a driving spring 13 are arranged on the connecting part 11. A rotation limiting head 121 and a linkage head 122 are arranged on the control plate 12. The driving spring 13 is used to push the rotation limiting head 121 and the linkage head 122 towards the mounting groove 41.

[0023] The disassembly and assembly process of the lens assembly 3 includes the following steps: S1, Insert the lens assembly 3 into the mounting groove 41 in the position to be installed, and the rotation limiting head 121 releases the limiting effect on the mounting block 4. S2, Rotate the mounting block 4 so that the lens assembly 3 in the position to be installed and the lens assembly 3 in the using position are interchanged. S3, Remove the lens assembly 3 in the position to be installed after the interchange, and the rotation limiting head 121 is inserted into the mounting groove 41 under the action of the driving spring 13.

[0024] Step S1 specifically includes: S11, The lens assembly 3 is inserted into the mounting groove 41, and the rotation limiting head 121 is pushed from the position of the mounting groove 41 to the position of the rotation limiting hole 43. S12, The linkage head 122 moves away from the linkage rod 51 along with the rotation limiting head 121. In S13, the linkage rod 51 moves towards the direction close to the linkage head 122 under the action of the linkage spring 52, and the fixed rod 5 is slightly inserted into the fixing hole through the linkage member 53.

[0025] Step S2 specifically includes: In S21, the mounting block 4 is rotated to misalign the rotation-limiting hole 43 with the rotation-limiting head 121, and the control board 12 further moves backward. In S22, the linkage head 122 further moves away from the linkage rod 51 along with the rotation-limiting head 121. In S23, the linkage rod 51 moves towards the direction close to the linkage head 122 under the action of the linkage spring 52, and the fixed rod 5 is inserted into the fixing hole through the linkage member 53.

[0026] Embodiment 1: Taking the attached Figure 1 to the attached Figure 4 as an example, the design of the present invention has the following effects: Effect 1: When the lens assembly 3 to be installed is not installed at the position to be installed, the mounting block 4 cannot rotate, thus ensuring the convenience of using the lens assembly 3 at the using position. Effect 2: When the lens assembly 3 to be installed is installed at the position to be installed, the lens assembly 3 can push the control board 12 to move through the rotation-limiting head 121, so that the fixed rod 5 is slightly inserted into the fixing hole. At this time, both the lens assembly 3 and the mounting block 4 are in a slightly fixed state, and not only can the lens assembly 3 be inserted and removed, but also the mounting block 4 can be rotated. And since the two mounting grooves 41 are in symmetric positions, after the lens assembly 3 is installed in the mounting groove 41 at the position to be installed, the effect of the lens assembly 3 can be tried by flipping the sunglasses.

[0027] Effect 3: When the mounting block 4 is rotated, the control board 12 can be further pushed to move through the rotation-limiting head 121, so that the fixed rod 5 is further inserted into the fixing hole to completely fix the lens assembly 3 and prevent the insertion and removal of the lens assembly 3.

[0028] In summary, the trial fitting, replacement, disassembly and assembly of the lens assembly 3 can be achieved conveniently and quickly.

[0029] It should be noted that: the spring coefficient of the driving spring 13 should be greater than that of the linkage spring 52.

[0030] The present invention is further configured as: the linkage member 53 includes a coaxial active gear and a passive gear, the linkage rod 51 is provided with a first tooth structure meshing with the active gear, and the fixed rod 5 is provided with a second tooth structure meshing with the passive gear.

[0031] The design of this structure, such as Figure 5As shown in the simplified diagram of the linkage member 53, the lower part is the driving gear and the linkage rod 51, and the upper part is the driven gear and the fixed rod 5. When the linkage rod 51 moves under the action of the linkage spring 52, the driving gear can be rotated through the first tooth structure. Since the driving gear and the driven gear are coaxially arranged, when the driving gear rotates, the driven gear rotates accordingly, and the fixed rod 5 is moved through the second tooth structure.

[0032] It should be noted that the moving distances of the linkage rod 51 and the fixed rod 5 can be changed by designing the sizes of the driving gear and the driven gear.

[0033] The present invention is further configured such that arc-shaped guiding surfaces are provided at the ends of the limiting rotating head 121, the linkage head 122, and the fixed rod 5. The design of this structure can facilitate the insertion and removal installation of the lens assembly 3 and the rotation of the mounting block 4.

[0034] The present invention is further configured such that the linkage rod 51 includes a main body portion 511 and a rod portion 512. The diameter length dimension of the main body portion 511 is greater than the diameter length dimension of the linkage hole 44, and the diameter length dimension of the rod portion 512 is less than the diameter length dimension of the linkage hole 44.

[0035] As shown in the design of this structure, Figure 4 since the diameter length dimension of the rod portion 512 is less than the diameter length dimension of the linkage hole 44, when the linkage head 122 moves out of the linkage hole 44, the rod portion 512 can be inserted into the linkage hole 44, so that the linkage rod 51 is further displaced.

[0036] The present invention is further configured such that a flexible sealing strip 6 is detachably installed in the installation groove 41. The design of this structure can, when the lens assembly 3 does not need to be replaced, block the upper part of the installation groove 41 through the flexible sealing strip 6, thereby improving the appearance of the spectacle frame 1 and also preventing impurities from falling into the installation groove 41.

[0037] The present invention is further configured such that the temple 2 includes a first connection section 21 and a second connection section 22. One end of the first connection section 21 is connected to the spectacle frame 1, and the other end is rotatably connected to the second connection section 22. As shown in Figure 1 and Figure 2 When the rear half section of the temple 2 is rotatably connected, the spectacle can be simply worn by rotating the rear half section to test the effect of the lens assembly 3 at the position to be installed.

[0038] The present invention is further configured such that the temple 2 further includes a hinge portion 23. The hinge portion 23 is connected to one side of the connection portion 11. A limited rotation groove 24 is provided on the side of the hinge portion 23 facing the spectacle frame 1. A limited movement head 123 is provided on the control board 12, and a limited movement hole for the limited movement head 123 to extend out is provided on the spectacle frame 1.

[0039] As shown inFigure 6 As shown in the figure, as the second embodiment of the present application, a limited rotation head 121 and a limited movement head 123 are respectively arranged at both ends of the control board 12. When the limited rotation hole 43 is aligned with the limited movement head 123, and the lens assembly 3 is inserted into the installation groove 41 at the to-be-installed position, the control board 12 moves from the installation block 4 towards the hinge portion 23. At this time, the limited movement head 123 can pass through the limited movement hole and be inserted into the limited rotation groove 24, thereby restricting the rotation of the temple 2 and ensuring that the lens assembly 3 does not interfere with the temple 2 during the rotation of the installation block 4.

[0040] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
