[0030] Please refer to Figures 1 to 4 In an embodiment, a multi-stage hinge structure 100 comprises a head 1, an insert 2, a temple assembly 3 and an elastic clamping group 4. Wherein, the front end of the insert 2 is rotatably connected with the head 1 through a screw 5, and the end of the insert 2 is provided with an insertion end 21. The front end of the temple assembly 3 is hollow, and the top is provided with an opening. The elastic clamping group 4 is rotatably arranged in the hollow end of the temple assembly 3, and the front end of the elastic clamping group 4 is provided with a clamping head 45 corresponding to the insertion end 21.

[0031] In the above multi-stage hinge structure 100, one end of the insert 2 is rotatably connected with the head 1 to form a hinge, and the other end of the insert 2 is detachably inserted with the temple assembly 3. Specifically, the end of the insert 2 is provided with an insertion end 21, and the end of the temple assembly 3 is rotatably provided with an elastic clamping group 4. When the insertion end 21 is inserted into the end of the temple assembly 3, it will abut the elastic clamping group 4, so that the elastic clamping group 4 is rotated to lift the clamping head 45. When the clamping head 45 is in position corresponding to the insertion end 21, the clamping head 45 moves downward under the action of elastic restoring force and is clamped and positioned with the insertion end 21, realizing the modular installation of the temple assembly 3. When the hinge between the insert 2 and the head 1 fails, only need to press the elastic clamping group 4 downward, so that the clamping head 45 is separated from the insertion end 21, and the temple assembly 3 can be disassembled. Only the insert 2 needs to be replaced, which greatly saves the maintenance cost. In addition, different styles of temple assemblies 3 can be quickly and conveniently replaced according to user needs.

[0032] Please refer to Figure 1 and Figure 2 In an embodiment, the insert 2 is extended with a plate body 22, and the screw 5 is arranged through the plate body 22 and the end of the head 1, so that the insert 2 can rotate around the head 1.

[0033] In an embodiment, the plug-in end 21 comprises a tooth groove structure 23 extending vertically upward from the plug-in 2, for cooperating with the clamping head 45 of the elastic clamping group 4. The plug-in 2 further comprises a vertical extension sealing plate 24 and a horizontal extension base plate 25, and the tooth groove structure 23 is formed on the base plate 25 and is spaced apart from the sealing plate 24. When the plug-in 2 is inserted into the elastic clamping group 4, the sealing plate 24 can be positioned in abutment with the port of the elastic clamping group 4. Preferably, the tooth groove structure 23 comprises at least two horizontally spaced tooth bars 231, and when the clamping head 45 of the elastic clamping group 4 is clamped and slid between the two tooth bars 231, it is the first plug-in position. When the clamping head 45 of the elastic clamping group 4 continues to slide and clamp between the tooth bar 231 and the inner wall of the end of the temple assembly 3, it is the second plug-in position. It can be understood that the utility model is not limited to two positions, and a plurality of tooth bars 231 can be provided to form a plurality of positions for plug-in to meet different plug-in length requirements.

[0034] In an embodiment of the temple assembly 3, the temple assembly 3 comprises a plug-in housing 31, an extension body 32 and a temple 33. The plug-in housing 31 is hollow inside and open at the top and front end, for accommodating the elastic clamping group 4, the extension body 32 is arranged at the end of the plug-in housing 31 away from the plug-in 2, and the temple 33 can be sleeved and fixed on the extension body 32. The plug-in housing 31 and the extension body 32 can be integrally formed, and in addition, the extension body 32 can be made of metal.

[0035] Please refer to Figure 1 , Figure 2 and Figure 4 , the elastic clamping group 4 comprises a movable clamping plate 41, an elastic member 42 and a latch 43. The movable clamping plate 41 is provided with a flange 44 extending vertically downward in the middle, and the flange 44 and the inner wall of the plug-in housing 31 are penetrated by the latch 43, so that the movable clamping plate 41 can rotate up and down in the plug-in housing 31. The front end of the movable clamping plate 41 is provided with a clamping head 45 extending vertically downward, which is used for clamping and positioning with the tooth groove structure 23 on the plug-in 2. The rear end of the movable clamping plate 41 is provided with a protruding flange 46 extending vertically downward, and the elastic member 42 can be a spring and is sleeved on the flange 46 and abuts against the inner wall of the plug-in housing 31.

[0036] In the initial state, the rear end of the movable clamping plate 41 is raised and exposed from the top opening of the plug-in housing 31 under the elastic force of the elastic member 42.

[0037] In actual assembly, when the plug-in end 21 of the plug-in part 2 is inserted into the plug-in shell 31 of the temple assembly 3, the rear end of the movable clamping plate 41 can be pressed downward, and at the same time, the plug-in end 21 pushes the movable clamping plate 41 to drive the clamping head 45 to rotate upward, and the elastic member 42 is compressed. When the plug-in end 21 continues to be inserted and the clamping head 45 is opposite to the tooth groove structure 23, under the elastic restoring force of the elastic member 42, the clamping head 45 is inserted between the two racks 231, and the movable clamping plate 41 reaches a balanced state, achieving the effect of stable installation. When disassembly is needed, the rear end of the movable clamping plate 41 can be pressed downward to separate the clamping head 45 from the tooth groove structure 23, and then the plug-in part 2 can be pulled out.

[0038] It should be noted that the groove formed between every two racks 231 is one gear, and as the plug-in part 2 is gradually pushed in, multi-gear plug-in positioning between the plug-in part 2 and the temple assembly 3 can be achieved, and the last gear is the groove formed between the rack 231 and the inner wall of the front end of the plug-in shell 31.

[0039] The structure not only enables quick disassembly and assembly between the plug-in part 2 and the temple assembly 3, but also improves the stability and service life of the structure through the tooth groove clamping mode, and is particularly suitable for eyewear products that need to replace temples or modular design.
