[0029] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be exchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally a category, and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in a "or" relationship.

[0030] The following description, in conjunction with the accompanying drawings, details a replaceable temple elastic hinge provided in this application through specific embodiments and application scenarios.

[0031] Example 1:

[0032] like Figures 1 to 3 As shown, this application embodiment provides a replaceable temple elastic hinge, including an outer frame 1, an outer temple 2 and a hinge 3; the hinge 3 includes a post 31 and a connecting block 32, the post 31 is fixedly installed on the outer frame 1, one end of the connecting block 32 is hinged to the post 31, and the other end is installed on the outer temple 2 through a detachable structure 4.

[0033] Furthermore, the detachable structure 4 includes an elastic block 41, a plug-in block 42, a sliding groove 43, and a plug-in slot 44. The elastic block 41 is fixedly installed at the end of the connecting block 32 away from the post head 31. The bottom end of the elastic block 41 is provided with a plug-in block 42. The front end of the outer temple 2 is provided with a sliding groove 43 along its length direction. The sliding groove 43 is provided with a plug-in slot 44 corresponding to the plug-in block 42. The elastic block 41 can slide into the sliding groove 43 and push the plug-in block 42 into the plug-in slot 44.

[0034] Furthermore, the elastic block 41 includes an inverted U-shaped block 411 and an L-shaped block 412 with openings facing the connecting block 32. The starting end of the inverted U-shaped block 411 is fixedly connected to the connecting block 32, and the ending end is fixedly connected to the L-shaped block 412. The plug-in block 42 is fixedly installed at the bottom end of the L-shaped block 412.

[0035] In this embodiment of the application, due to the above-described structure, when the temple 2 needs to be disassembled, the insertion block 42 can be lifted by tweezers, causing the insertion block 42 to detach from the insertion groove 44, and the C-shaped block 411 and L-shaped block 412 to be squeezed, causing them to deform. At this time, the temple 2 can be pulled out by pulling it out. When installing the temple 2, the C-shaped block 411 and L-shaped block 412 are squeezed and inserted into the sliding groove 43 until the insertion block 42 slides to the insertion groove 44. The C-shaped block 411 and L-shaped block 412 elastically recover, pushing the insertion block 42 into the insertion groove 44, locking the position, and completing the installation.

[0036] Example 2:

[0037] like Figure 2 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the pile head 31 has several grooves 311 staggered on both sides.

[0038] Furthermore, the pile head 31 is made of an elastic material.

[0039] In this embodiment of the application, due to the above-mentioned structure, a plurality of grooves 311 are provided alternately on both sides of the pile head 31. By setting the plurality of grooves 311, the elasticity of the pile head 31 can be improved, giving it better elastic displacement space, thereby better reducing the pressure on the user and making it suitable for users with different face shapes.

[0040] The pile head 31 is made of TR90 material, which is a high-molecular material with shape memory and super toughness. It can effectively resist the risk of bending or breaking and maintain the integrity and stability of the structure.

[0041] Example 3:

[0042] like Figures 4 to 6 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the outer frame 1 is provided with a connected mounting groove 51 and an adjustment groove 52. A cover plate 53 is slidably installed in the mounting groove 51. A locking plate 54 is provided at the bottom of the cover plate 53. A locking block 55 is provided on one side of the locking plate 54. A locking fastener 56 is floatingly installed in the adjustment groove 52. The locking fastener 56 is used to fix the locking block 55 in the current position or to unlock the locking block 55.

[0043] Furthermore, the locking device 56 includes a pressing block 561, a locking block 562, and an unlocking groove 563. The top end of the locking block 55 abuts against the bottom end of the locking block 562. The locking block 562 has an unlocking groove 563 that slides with the locking block 55 on the side facing the locking block 55. One end of the locking block 562 extends out of the outer frame 1 and is fixedly connected to the pressing block 561. By pressing the pressing block 561, the locking block 55 and the unlocking groove 563 can be aligned.

[0044] Furthermore, a pop-out block 57 is floatingly installed in the mounting slot 51, with the top of the pop-out block 57 abutting against the bottom of the snap-fit ​​block 55.

[0045] In this embodiment of the application, due to the above-described structure, when replacing the lens, by pressing the corresponding pair of pressing blocks 561, the pressing blocks 561 will push the locking block 562 to slide along the slide groove 43 and squeeze the corresponding spring until the locking blocks 55 on both sides are aligned with the corresponding unlocking grooves 563. The pop-out block 57 will push the cover plate 53 to slide upward and lock into the unlocking groove 563. At this time, the cover plate 53 can be pulled out, so that the lens can be taken out from the top of the frame 1. After inserting the new lens into the frame 1, the cover plate 53 is reinserted. The cover plate 53 slides downward, and the locking block 55 will push the pop-out block 57 to slide downward until the locking block 55 and the pop-out block 57 are both disengaged from the unlocking groove 563. Under the action of the corresponding spring, the locking block 562 and the pressing block 561 are reset, and the locking block 562 abuts against the top of the locking block 55 again, so that the cover plate 53 is engaged with the frame 1, thereby realizing the replacement of the lens.
