[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Such as Figures 1-9As shown, the utility model discloses a spectacles hinge that is easy to disassemble and assemble, including a base 1 and a connecting piece 2, wherein the base 1 is provided with a screw hole 321 that is threadedly matched with the connecting piece 2, and the front side of the temple 6 is inserted into the base 1, and then the connecting piece 2 is installed, at this time, the connecting piece 2 will be inserted into the front side of the temple 6 and the bottom will be threadedly matched with the screw hole 321 of the base 1, so that the temple 6 can be rotated compared to the hinge, and the bottom of the base 1 is detachably installed with a matching seat 3 by means of buckles, bolts, etc., and the matching seat 3 includes a matching section 32 provided with a screw hole 321 and a matching section 32 located at the matching The fixing section 31 below the engaging section 32 is in the shape of a hexagonal prism. 1. Since the screw hole 321 is located on the engaging section 32, and the engaging seat 3 is detachably connected to the base 1, when the screw hole 321 is worn over time, the engaging seat 3 can be removed and replaced with a new engaging seat 3 to complete the engagement between the connector 2 and the screw hole 321; 2. Since the fixing section 31 is in the shape of a polygonal prism, after the engaging seat 3 is installed into the base 1, the engaging seat 3 cannot rotate relative to the base 1, so that the engaging seat 3 can be stably located in the base 1.

[0032] The width of the fixed section 31 is greater than the width of the matching section 32. The fixed section 31 is provided with a plurality of positioning blocks 4 at intervals upward. The base 1 is provided with a matching groove 11 in the circumferential direction of the matching section 32 and a positioning block 12 is provided below the matching groove 11. Each positioning block 4 includes an insertion section 41 for inserting the positioning block 12 and a limiting section 42 located above the positioning block 12. The positioning block 12 is provided with a positioning groove 121 for each insertion section 41 to pass through. When the matching seat 3 is installed in the base 1 to After that, the limiting sections 42 of each positioning plug 4 located above the fixed section 31 need to be forcibly deformed and pass over the positioning block 12 upward so that each limiting section 42 can be stably located above the positioning block 12 without the action of external force, so that the matching seat 3 can be stably located on the base 1. When the matching seat 3 needs to be removed from the base 1, it is necessary to first rotate the connecting piece 2 to separate it from the screw hole 321, and then reach in from the top of the base 1 to pry each limiting piece so that it is forced to separate downward from the positioning block 12, thereby realizing the separation of the base 1 and the matching seat 3.

[0033] Preferably, the width of each positioning groove 121 is greater than the width of the corresponding insertion section 41 and smaller than the width of the corresponding limiting section 42. Since the width of each positioning groove 121 is greater than the corresponding insertion section 41, each insertion section 41 can enter and be placed in the positioning groove 121 more smoothly, and the positioning groove that is greater than the insertion section 41 and smaller than the width of the limiting section 42 allows the limiting section 42 to more smoothly pass over the corresponding positioning groove 121 and then be located above the positioning stop block 12.

[0034] Among them, each of the limiting sections 42 includes an extension portion 421, a connecting portion 422 and a conflicting portion 423. Each of the extending portions 421 extends in the vertical direction and is fixedly installed on the corresponding insertion section 41 by means of integral molding, bonding, etc. Each of the conflicting portions 423 is parallel to the corresponding extending portion 421, and one end of each of the connecting portions 422 is fixed to the corresponding extending portion 421 and the other end is fixed to the corresponding conflicting portion 423. Each of the connecting portions 422 is inclined from the inside to the outside from top to bottom, and each of the conflicting portions 423 is against the positioning block 12. 1. Since each of the conflicting portions 423 is parallel to the corresponding extending portion 421 and the length directions of both extend up and down, each of the limiting sections 42 needs to forcibly cross the corresponding positioning groove 12 1. At this time, each abutment portion 423 can drive the corresponding connecting section toward the extending portion 421, so that the abutment portion 423 and the connecting portion 422 can both enter the corresponding positioning groove 121 and move upward. After the abutment portion 423 and the connecting portion 422 pass through the corresponding positioning groove 121, the abutment portion 423 loses the effect of external force and can resist the positioning block 12, so that the matching seat 3 can be stably located in the base 1; 2. Since each connecting portion 422 is inclined from top to bottom, when each limiting segment 42 is aligned with the corresponding positioning groove 121, the first thing that is contacted is the narrowest part of the width of each limiting segment 42, so that each limiting segment 42 can be squeezed more smoothly and forced to cross the corresponding positioning groove 121 upward.

[0035] In addition, the base 1 also includes a socket 13 located above the mating seat 3, and the connecting piece 2 includes a working section 21 in which the socket 13 is inserted. The working section 21 is provided with a hexagonal contact groove 211, and the contact groove 211 is designed to be precisely matched with a hexagonal wrench. This design can ensure a close contact surface between the tool and the bolt, reducing the risk of slipping during the tightening process.

[0036] Among them, it also includes a dust cover 5 located above the working section 21, the upper end surface of the dust cover 5 is flush with the upper end surface of the base 1, and the dust cover 5 is detachably connected to the base 1 by bolts and the like. 1. The dust cover 5 can cover and prevent dust from the connector 2 and the mating seat 3 located in the base 1, so that it is difficult for external dust to pass through the dust cover 5 and fall into the base 1; 2. Since the dust cover 5 is detachably connected to the base 1, if it is necessary to remove the connector 2 from the base 1 or to remove the mating seat 3 by taking out the connector 2 and then extending into the base 1, it is necessary to remove the dust cover 5 from the base 1. Therefore, the setting of the dust cover 5 prevents irrelevant personnel from touching and removing the connector 2 and the mating seat 3.

[0037] Preferably, a plurality of lower magnets 51 are protrudingly provided at the bottom of the dust-proof cover plate 5, and upper magnets 14 are provided on the base 1 corresponding to the respective lower magnets 51. Since the lower magnets 51 of the dust-proof cover plate 5 will be attracted to the upper magnets 14 on the base 1, after the dust-proof cover plate 5 is installed on the base 1, the dust-proof cover plate 5 can be stably located on the base 1 without external force. When it needs to be removed, only an upward acting force needs to be provided to separate the lower magnets 51 on the dust-proof cover plate 5 from the upper magnets 14 on the base 1, and then the dust-proof cover plate 5 can be removed.

[0038] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
