Specifically, the open slot 201 of the second connecting member 200 can accommodate the first gear 400 and the second gear 300, the first gear 400 and the second gear 300 can rotate relative to the second connecting member 200, the second gear 300 is fixed at the outer side of the first connecting member 100, when the first connecting member 100 and the second connecting member 200 need to be overlapped, the first connecting member 100 is pressed with force, at the moment, the second gear 300 rotates along with the first connecting member 100 to further drive the first gear 400 to rotate, and thus, the overlapping of the first connecting member 100 and the second connecting member 200 is realized; when the first connecting piece 100 and the second connecting piece 200 need to be opened, the first connecting piece 100 is pulled reversely, and at this time, the second gear 300 rotates reversely along with the first connecting piece 100, so as to drive the first gear 400 to rotate reversely, thereby realizing the opening of the first connecting piece 100 and the second connecting piece 200.
In a specific embodiment, the gear hinge assembly further includes two locking screws 600, through holes 401 are disposed between the first gear 400 and the second gear 300, and the locking screws 600 sequentially pass through the through holes 202 of one side of the open slot 201 and the through holes 401 of the first gear 400 or the second gear 300 and then are locked to the through holes 202 of the other side of the open slot 201. In this scheme, the positions of the first gear 400 and the second gear 300 can be respectively limited by the two locking screws 600, so that the first gear 400 and the second gear 300 cannot be displaced, and the stability and reliability of the connection structure are improved.

In a side-by-side arrangement, the flap 501 may also snap onto the second connector 200. For example, the second connecting member 200 has a limiting groove on each side, and the above-mentioned folded edge 501 is directly inserted into the limiting groove. The limiting groove can be replaced by a limiting hole, the corresponding folded edge 501 can be a limiting column, and the limiting column can extend into the limiting hole and is in limiting fit with the limiting hole.
Considering that the end of the second connector 200 is provided with the through hole 202, which brings about a problem of low mechanical strength, the end of the second connector 200 is also set to be arc-shaped in the scheme, so that the visual effect can be improved while the mechanical strength is increased.
When the spacer 500 is installed, one side of the spacer 500 with the folded edge 501 is inserted into the through hole 401 of the first gear 400 or the second gear 300, then the first gear 400 and the second gear 300 which are engaged with each other are accommodated in the open groove 201, and finally the locking screw 600 is sequentially inserted through the through hole 202 of one side of the second connecting member 200 and the through hole 202 of the first gear 400 or the second gear 300 and then locked in the through hole 202 of the other side of the second connecting member 200.
In a specific embodiment, the through hole 202 of the second connector 200 includes a first hole section 221 near the outer wall of the second connector 200, and a second hole section 222 near the inner wall of the second connector 200 and communicating with the first hole section 221, wherein the first hole section 221 has a larger hole diameter than the second hole section 222. Through the through hole 202 of the above structure, the locking screw 600 can be completely accommodated in the second connecting member 200, and the visual effect is improved. Specifically, the nut of the locking screw 600 is received in the first hole section 221 of the through hole 202 on one side of the second connector 200, and the screw of the locking screw 600 is received in the second hole section 222, the through hole 202 of the first gear 400 or the second gear 300, and the through hole 202 on the other side of the second connector 200. In a preferred embodiment, the through hole 202 of one side of the second connector 200 includes a first hole section 221 and a second hole section 222, and the hole diameter of the through hole 202 of the other side of the second connector 200 is equal. Further, the nut of the locking screw 600 is provided with a straight groove, a cross-shaped groove, or a polygonal groove to facilitate locking.
Further, a welding portion 300 radially extends from an outer side of the second gear 300, and an end of the first connector 100 is welded to the welding portion 300. Specifically, the welding portion 300 has a planar welding surface, and the end of the first connector 100 is directly welded to the welding surface. Preferably, the first connector 100 is welded to the welding surface at a wider side, so that the welding area is large, and the reliability of welding can be improved. The welding surface is disposed at an angle to the tooth surface of the first gear 400 or the second gear 300.
Further, the number of teeth of the first gear 400 is 6-18, the number of teeth of the second gear 300 is 6-18, the radius of the first gear 400 is 1.2mm-4mm, and the radius of the second gear 300 is 1.2mm-4 mm. The gear radius of the first gear 400 and the second gear 300 is less than 1.2mm, and the number of teeth is less than 6, which can cause the unsmooth opening and closing of the first gear 400 and the second gear 300; when the number of teeth of the first gear 400 and the second gear 300 is greater than 18, the gears are too small and easily deformed. The gear radius of the first gear 400 and the second gear 300 is more than 4mm, and the number of teeth is less than 6, which causes the first gear 400 and the second gear 300 to be unsmooth to open and close and have rough appearance; and when the number of teeth of the first gear 400 and the second gear 300 is greater than 18 and the radius of the gear is greater than 4mm, the humanization of the glasses structure is lost, and the glasses hinge structure is not suitable for the glasses hinge structure. The number of teeth of the first gear 400 and the second gear 300 may be 6, 10, 14, or 18, and the specific number of the teeth may be set according to design requirements. Considering that the outer side of the second gear 300 is formed with the welded portion, the number of teeth of the second gear 300 is smaller than that of the first gear 400 in practical use. The gear radius of the first gear 400 and the second gear 300 may be 1.2mm, 1.9mm, 2.6mm, 3.3mm, and 4mm, and specifically, the gear radius may be set according to design requirements.
