DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-7 This application is described in further detail.

[0029] The present application provides a modular and easy-to-assemble eyeglass frame, such as Figure 1 and Figure 2 As shown, it includes a frame 1, a connecting component 2 and temples 3. The frame 1 includes a brow bridge 12 and a mirror bridge 11 integrally formed on both sides of the brow bridge 12; the two mirror bridges 11 on both sides of the brow bridge 12 are symmetrically arranged, and the bottom wall of each mirror bridge 11 is provided with a mounting groove 111, and the shape of the mounting groove 111 is adapted to the lens 9. In addition, the mirror bridge 11 is a semi-frame structure with an opening on one side. This design not only reduces the weight of the glasses, but also makes the lens 9 easier to install and remove. A nose pad 8 is provided on the side of the mirror bridge 11 close to the brow bridge 12, and two nose pads 8 are symmetrically arranged. The nose pad 8 includes a connecting rod 81 and a protective pad 82 connected to one end of the connecting rod 81, and one end of the connecting rod 81 is fixed to the mirror bridge 11, and the protective pad 82 is specifically made of silicone to improve wearing comfort.

[0030] like Figure 2As shown, the connection component 2 is a key part of the eyeglass frame, which connects the lens 9 and the bridge 11 to ensure the overall stability. The connection component 2 includes a bearing column 21 and a fixed connecting piece 22. The fixed connecting piece 22 is used to be fixedly connected to the lens 9. In this embodiment, the fixed connecting piece 22 is integrally formed on the top of the lens 9, and the material of the fixed connecting piece 22 is the same as that of the lens 9. A connecting hole 221 is provided on the fixed connecting piece 22. When installing the lens 9, the fixed connecting piece 22 needs to be inserted into the installation groove 111, and the groove width of the installation groove 111 is greater than the thickness of the fixed connecting piece 22.

[0031] like Figure 2 As shown, one end of the bearing column 21 passes through the inner wall of the mounting groove 111 from the outside of the mirror bridge 11 and is slidably connected to the mounting groove 111, and the other end is located outside the mirror bridge 11 and is fixed with a pull plate 24. The bearing column 21 is specifically configured to be cylindrical, and the diameter of the bearing column 21 is smaller than the aperture of the connecting hole 221, which can reduce the difficulty of assembly. After inserting the connecting piece into the mounting groove 111, slide the bearing column 21 so that the bearing column 21 is passed through the connecting hole 221, and the fixed connecting piece 22 can be hung on the bearing column 21, thereby realizing the connection of the lens 9 on the mirror bridge 11. When it is necessary to install or remove the lens 9, it is only necessary to pull the pull plate 24 to overcome the elastic force of the force-applying member 25, and the bearing column 21 can be pulled out from the mounting groove 111, which is simple and quick to operate. When the glasses are in an extreme temperature environment, the lens 9 will be deformed; the lens 9 is mounted on the frame 1 by hanging by a fixed connecting piece 22. After the lens 9 is deformed and enlarged, it is not easy for the lens 9 to directly contact the frame 1, and it is not easy for the lens 9 to be squeezed by the frame 1 and damaged.

[0032] like Figure 2 As shown, a force member 25 is connected between the pull plate 24 and the outer wall of the mirror bridge 11. The force member 25 can be a spring or other elastic element, which is used to drive the pull plate 24 to move in the direction close to the mirror bridge 11. In this embodiment, the force member 25 is specifically configured as a force spring, and the force spring is sleeved outside the bearing column 21. When the fixed connecting piece 22 needs to be installed in the installation groove 111, the pull plate 24 is pulled to drive the bearing column 21 to move in the direction of sliding out of the installation groove 111, so that a space for accommodating the fixed connecting piece 22 is formed in the installation groove 111. At this time, the force spring is extended. The fixed connecting piece 22 can be inserted into the accommodating groove 41. Then, the pull plate 24 is released, and the force spring shrinks to its original length, driving the bearing column 21 to restore its original state, so that the bearing column 21 is inserted into the connecting hole 221.

[0033] like Figure 3 and Figure 4As shown, the connection assembly 2 also includes an elastic clamping member 23, which is fixed in the mounting groove 111. The elastic clamping member 23 is specifically configured as a clamping block with a clamping groove 231, and the clamping block is made of elastic material. When the fixed connecting piece 22 is located in the mounting groove 111, the side of the fixed connecting piece 22 is clamped into the clamping groove 231 to ensure the stability of the fixed connecting piece 22 in the mounting groove 111, and prevent the lens 9 from loosening or falling off during use. In this embodiment, two elastic clamping members 23 are fixed in one mounting groove 111 at intervals.

[0034] like Figure 2 and Figure 3 As shown, in order to enhance the protective performance of the glasses, an anti-drop strip 4 can be provided at the opening of the bridge 11. A receiving groove 41 for the lens 9 to be clamped is provided on the side of the anti-drop strip 4 close to the bridge 11. One end of the anti-drop strip 4 is hinged to the end of the bridge 11 away from the brow bridge 12, and the other end of the anti-drop strip 4 is detachably connected to the end of the bridge 11 close to the brow bridge 12. Figure 3 and Figure 5 As shown, an elastic snap block 42 is fixed to the end of the anti-fall strip 4 away from its own rotating end, and one end of the elastic snap block 42 gradually shrinks in the direction away from the anti-fall strip 4. In this embodiment, the snap block is specifically configured to be a frustum. A snap groove 112 is provided at one end of the bridge 11 close to the brow bridge 12. By snapping the snap block into the snap groove 112, the detachable connection of the anti-fall strip 4 on the brow bridge 12 can be achieved. The anti-fall strip 4 is made of elastic material, which can play a buffering role when the glasses are impacted and protect the lens 9 from damage.

[0035] like Figure 1 and Figure 6As shown, both sides of the frame 1 are provided with temples 3, and the temples 3 are connected to the bridge 11 in a detachable manner. This design allows the temples 3 to be replaced as needed, further meeting the personalized needs of consumers. The end of the bridge 11 away from the brow bridge 12 is fixed to the connecting seat 5, and one end of the temple 3 is provided with a connecting shaft 311. A bearing groove 51 is provided on the side wall of the connecting seat 5, and a switch member 6 is movably provided on the connecting seat 5. The switch member 6 is used to open or close the opening of the bearing groove 51, so as to control the connection state of the temple 3 and the frame 1. The temple 3 can be easily installed and removed, and the stability of the connection is ensured. Specifically, the switch member 6 may include a switch arc plate 61, and a yielding port 611 is provided on one side of the switch arc plate 61. An adjustment groove 52 for the switch arc plate 61 to rotate is provided on the inner side wall of the bearing groove 51. An operating rod 62 is fixed to one end of the switch arc plate 61, and a sliding hole 53 is provided on the top wall of the connecting seat 5, and one end of the operating rod 62 is slidably provided in the sliding hole 53. An operating head 621 is fixed to one end of the operating rod 62 away from the switch arc plate 61. The operating head 621 is located outside the connecting seat 5, and the bottom wall of the operating head 621 can abut against the side wall of the connecting seat 5 with the sliding hole 53. By rotating the operating rod 62, the opening 611 can be aligned or misaligned with the opening of the bearing groove 51, thereby realizing the opening or closing of the bearing groove 51. In other embodiments, in order to improve the sliding stability of the switch arc plate 61 in the adjustment groove 52, a guide rib is fixed on the outer wall of the switch arc plate 61, and an arc-shaped guide groove is opened on the inner wall of the adjustment groove 52, so that the guide rib slides in the guide groove.

[0036] like Figure 7As shown, the temple 3 includes a cross beam portion 31 and an ear hook portion 32 that are connected to each other. A storage groove 312 is provided on the outer side wall of the cross beam portion 31 close to the frame 1, and a lanyard 7 is clamped in the storage groove 312; one end of the lanyard 7 is hinged to the inner side wall of the storage groove 312, and the other end is detachably connected to the end of the ear hook portion 32 away from the cross beam portion 31. A locking member 71 may be provided at one end of the lanyard 7, and the locking member 71 includes a through rod 711 and a limiting spring piece 712 fixed to one end of the through rod 711. The spacing between the limiting spring piece 712 and the through rod 711 gradually increases toward the end close to the lanyard 7. In this embodiment, the limiting spring piece 712 is specifically configured as a dome shell structure, and a plurality of limiting spring pieces 712 are spaced apart along the length direction of the through rod 711. When the locking member 7 is located in the receiving slot 312, the limiting spring piece 712 is snapped into the receiving slot 312 to achieve stable installation of the lanyard 7 in the receiving slot 312. The ear hook portion 32 is provided with a locking hole 321 for the penetration rod 711 to pass through. When it is necessary to connect one end of the lanyard 7 to the ear hook portion 32, the penetration rod 711 is passed through the locking hole 321, and the limiting spring piece 712 on the penetration rod 711 passes through the locking hole 321 together with the penetration rod 711; the limiting spring piece 712 is used to pass through the locking hole 321 and abut against the outer wall of the ear hook portion 32, thereby achieving a detachable connection between one end of the ear hook and the ear hook portion 32. During use, the lanyard 7 can work together with the ear hook portion 32 to surround the user's ears; so that the glasses can be worn firmly on the user's head and are not easy to fall off.

[0037] In general, the modular and easy-to-assemble glasses frame of the present application realizes the independent replacement and adjustment of each component of the glasses through a clever structural design, meeting the consumer's demand for personalized glasses. At the same time, the elastic clamping member 23 is used to clamp and fix the connecting piece 22, and the anti-fall strip 4 is provided to ensure the safety and reliability of the glasses. In addition, by optimizing the design of components such as the switch member 6 and the hanging strap 7, the usability and wearing comfort of the glasses are further improved.

[0038] The implementation principle of a modular easy-to-assemble eyeglass frame 11 of the embodiment of the present application is as follows: when the pull plate 24 is pulled to drive the bearing column 21 to move in the direction of sliding out of the installation groove 111, a space for accommodating the fixed connecting piece 22 is formed in the installation groove 111, and then the fixed connecting piece 22 is inserted into the accommodating groove 41; when the fixed connecting piece 22 is inserted into the accommodating groove 41, the fixed connecting piece 22 needs to be aligned with the clamping groove 231 of the clamping block, so that after the fixed connecting piece 22 is inserted into the accommodating groove 41, the clamping block clamps the fixed connecting piece 22. Then, the pull plate 24 is released, and the bearing column 21 is restored to its original position under the action of the force spring and penetrated into the connecting hole 221. The anti-fall strip 4 is rotated to make one side of the lens 9 clamped into the accommodating groove 41 of the anti-fall strip 4, and then the buckle block is clamped into the clamping groove 112 to achieve the connection of the anti-fall strip 4 on the brow bridge 12. The operating lever 62 is rotated to align the clearance opening 611 with the opening of the bearing slot 51, and the opening of the bearing slot 51 is in an open state, and the connecting shaft 311 can be clamped into the bearing slot 51 along the opening of the bearing slot 51; after the operating lever 62 is rotated to misalign the clearance opening 611 with the opening of the bearing slot 51, the opening of the bearing slot 51 is in a closed state, and the inner side wall of the switch arc plate 61 can be abutted against the side wall of the connecting shaft 311, thereby achieving the purpose of locking the connecting shaft 311 and completing the stable connection of the temple 3 on the frame 1.
