Description

Technical Field

[0001] The present application belongs to the field of hinge technology, and specifically relates to a spring hinge for glasses. Background Art

[0002] Glasses are vision correction devices, typically consisting of lenses and frames, used to improve vision problems such as myopia, hyperopia, and presbyopia. Beyond their vision correction capabilities, modern glasses offer fashion, personalization, and eye protection, making them an indispensable accessory in many people's daily lives.

[0003] Spring hinges for glasses are typically used to rotatably connect glasses legs to glasses frames. This allows the legs to be rotated and folded into the frames when the glasses are not in use, making it easier to store and carry the glasses. When the glasses are worn, the legs can be elastically opened outward, making it easier to wear the glasses comfortably.

[0004] However, after the temples are rotated multiple times, the friction at the rotation point will be reduced, causing the connection between the temples to loosen, reducing the convenience of use. Utility Model Content

[0009] By adopting the above technical solution, the plug-in rod can limit and fix the abutment plate to avoid abutting the connecting screw before the friction force is reduced, causing excessive friction and making it inconvenient to rotate between the brackets.

[0010] In a preferred embodiment, an upper magnetic block is installed at one end of the plug rod, and a lower magnetic block corresponding to the upper magnetic block is installed inside the limiting slot.

[0011] By adopting the above technical solution, the stability of the plug-in rod inserted into the limiting slot is improved through the mutual magnetic attraction between the upper magnetic block and the lower magnetic block.

[0012] In a preferred embodiment, one end of the connecting block is provided with a pushing slope corresponding to the plug-in rod.

[0013] By adopting the above technical solution, the reset spring can be squeezed by the insertion movement of the insertion rod on the push ramp surface, so as to pull the abutment plate back into the interior of the movable bracket.

[0014] In a preferred embodiment, a slope is provided on one side of the movable bracket.

[0015] By adopting the above technical solution, the rotation between the fixing bracket and the plug-in block is not affected, thereby improving convenience.

[0016] In a preferred embodiment, a groove corresponding to the bolt is opened on one side of the threaded through hole, a magnetic block 1 is installed on one side surface of the bolt, and a magnetic block 2 corresponding to the magnetic block 1 is installed on one side surface of the groove.

[0017] By adopting the above technical solution, the stability of the connection between the bolt and the threaded through hole is improved through the magnetic attraction between the first magnetic block and the second magnetic block.

[0018] In a preferred embodiment, a non-slip pad is bonded to one side surface of the abutment plate.

[0019] By adopting the above technical solution, the friction between the abutment plate and the connecting screw is improved, and the stability of the connection between the brackets is maintained.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0021] In this application, when the friction of the connecting screw is reduced, the plug-in rod can be pulled out to release the restriction on the connecting block. Under the elastic force of the reset spring, the abutment plate abuts against the connecting screw, increasing the friction of the connection, maintaining its normal use, and reducing maintenance costs.

A limiting slot 19 corresponding to the plug-in rod 13 is provided on the surface of the connecting block 16. One end of the plug-in rod 13 is inserted into the limiting slot 19, so that the plug-in rod 13 can limit and fix the abutment plate 6 to avoid abutting the connecting screw 11 before the friction force is reduced, causing excessive friction, which makes it inconvenient to rotate between the brackets.

[0030] Reference Figure 2-3 An upper magnetic block 18 is installed at one end of the plug-in rod 13, and a lower magnetic block 20 corresponding to the upper magnetic block 18 is installed inside the limiting slot 19. The mutual magnetic attraction between the upper magnetic block 18 and the lower magnetic block 20 improves the stability of the plug-in rod 13 inserted into the limiting slot 19.

[0031] Reference Figure 2 One end of the connecting block 16 is provided with a pushing slope 15 corresponding to the plug-in rod 13. By plugging and moving the plug-in rod 13 on the surface of the pushing slope 15, the return spring 14 can be squeezed to pull the abutment plate 6 back into the interior of the movable bracket 9.

[0032] Reference Figure 1 A slope 8 is provided on one side of the movable bracket 9 so that the rotation between the fixed bracket 1 and the plug-in block 5 is not affected, thereby improving convenience.

[0033] Reference Figure 4 A groove 4 corresponding to the bolt 12 is provided on one side of the threaded through hole 3, a magnetic block 21 is installed on one side surface of the bolt 12, and a magnetic block 2 22 corresponding to the magnetic block 1 21 is installed on one side surface of the groove 4. The magnetic attraction between the magnetic block 1 21 and the magnetic block 2 22 improves the stability of the connection between the bolt 12 and the threaded through hole 3.

[0034] Reference Figure 2 A non-slip pad is bonded to one side surface of the abutment plate 6 to increase the friction between the abutment plate 6 and the connecting screw 11 and maintain the stability of the connection between the brackets.

[0035] The implementation principle of the embodiment of the eyeglass spring hinge of the present application is as follows:

[0036] After a long period of rotation, the friction of the connecting screw 11 decreases, and the connecting rod 13 is pulled out from the inside of the socket 7. Under the elastic force of the return spring 14, the abutment plate 6 is pushed to squeeze the connecting screw 11. In this way, the friction between the connecting screw 11 and the through hole 10 is increased to maintain its normal use. In addition, during installation, the connecting rod 13 is inserted into the inside of the socket 7. The plug-in movement of the connecting rod 13 on the surface of the pushing ramp 15 can squeeze the reset spring 14 and pull the abutment plate 6 back to the inside of the movable bracket 9, thereby limiting the abutment plate 6, making it convenient for the connecting screw 11 to be inserted into the inside of the through hole 10 for installation.
