Description

Technical Field

[0001] The utility model relates to the technical field of glasses, in particular to a hinge structure used between a temple and a frame. Background Art

[0002] Glasses are made up of lenses and frames, used to improve vision, protect the eyes, or for decorative purposes. The frame and temples are typically connected by a hinge, allowing for relative rotation. The hinge typically consists of two hinged parts: one fixed to the frame and the other to the temple. The heads of the two hinged parts overlap, and a screw passes through them, acting as a hinge axis, connecting them to each other, allowing the temples to rotate.

[0003] The existing frames and temples are connected by the above-mentioned hinges. This hinged fixing method lacks elasticity when the temples are opened. If people with large heads are encountered, or if the temples are occasionally pulled, or if the hinges are subjected to external forces, the hinges are very likely to become loose or even damaged. The temples at the hinges may also flip outward excessively, causing loosening and deformation. Utility Model Content

[0004] The utility model aims to provide a hinge structure between a temple and a frame, which has a simple structure, a hinge with damping properties, and prevents the problem of excessive deformation.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: a hinge structure for use between temples and frames, comprising a fixed head and a rotating part, the rotating part is rotatably hinged to the fixed head, one end of the fixed head is a positioning part, a limiting spring is provided on the outside of the positioning part, a symmetrical support arm is provided on one side of the rotating part, a circle of limiting grooves is provided on the inner side wall of the support arm, the positioning part is hinged between the support arms, and the limiting spring rotates movably in the limiting groove.

[0006] Preferably, the cross section of the positioning portion is arc-shaped, a positioning hole is provided on the side surface of the positioning portion, and an embedding hole is provided on the front surface of the positioning portion.

The other end of the limit spring is provided with protrusions on both sides, and the protrusions are rotatable in the limit slot. The embedded hole provides a more secure installation, preventing the limit spring from moving or detaching. The protrusions on the limit spring are used to limit the swing angle of the rotating member.

[0009] Preferably, a connecting hole is provided at the center of the support arm, the positioning hole on the positioning portion corresponds to the connecting hole, and positioning shafts are provided in the positioning hole and the connecting hole to facilitate disassembly and fixation.

[0010] Preferably, threads are provided inside the connecting hole and the positioning hole, and the positioning shaft is threadedly connected to the connecting hole and the positioning hole respectively.

[0011] Preferably: the positioning shaft adopts a screw.

[0013] Preferably, the other side surface of the rotating member is provided with a raised surface, and a mounting hole is provided through the raised surface. The design of the raised surface increases the thickness of the rotating member and improves the firmness of the connection.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0027] A hinged structure for connecting temples to frames, comprising a fixed head 1 and a rotating member 2. The rotating member 2 is rotatably hinged to the fixed head 1. One end of the fixed head 1 is a positioning portion 3, with a limiting spring 4 disposed on the outside of the positioning portion 3. The positioning portion 3 has an arc-shaped cross-section and a positioning hole 31 is provided on the side of the positioning portion 3. The limiting spring 4 is a C-shaped structure, and its shape matches that of the positioning portion 3, so that they fit together. A symmetrical support arm 5 is provided on one side of the rotating member 2. The inner wall of the support arm 5 is provided with a circle of limiting grooves 51. The positioning portion 3 is hinged between the support arms 5, and the limiting spring 4 rotates freely within the limiting groove 51.

[0028] By means of the limiting spring piece 4 arranged on the outside of the positioning part 3, the width of the temple can be made wider, which can improve the tightness of the connection between the positioning part 3 and the support arm 5 of the rotating part 2. A circle of limiting grooves 51 is provided on the inner wall of the support arm 5. The rotating part 2 can be rotated in the limiting groove 51 through the protruding block 41 of the limiting spring piece 4, and can be rotated at least 90 degrees. The protruding block 41 on the limiting spring piece 4 is used to limit the swing angle of the rotating part 2, which plays a limiting role to prevent the temple from excessive flipping and deformation. At the same time, the design of the limiting spring piece 4 increases the elasticity of the hinge, and the rotating part 2 can be slightly adjusted inward and outward elastically, so that the temple can be slightly adjusted.

[0029] In this embodiment, the front face of the positioning portion 3 is provided with an embedding hole 6, into which one end of the limiting spring piece 4 is mounted, with the limiting spring piece 4 entirely surrounding the outside of the positioning portion 3. The other end of the limiting spring piece 4 is provided with protrusions 41 on both sides, which movably rotate within the limiting groove 51. The embedding hole 6 provides a more secure installation, preventing the limiting spring piece 4 from moving or detaching. Furthermore, the protrusions 41 on the limiting spring piece 4 are used to limit the swing angle of the rotating member 2.

[0030] In this embodiment, a connecting hole 7 is provided in the center of the support arm 5, and the positioning hole 31 on the positioning part 3 corresponds to the connecting hole 7. The connecting hole 7 and the positioning hole 31 are provided with threads inside, and the positioning shaft is threadedly connected to the connecting hole 7 and the positioning hole 31 respectively. The positioning shaft adopts screws for easy disassembly and fixation.

[0031] In this embodiment, the rotating member 2 and the support arm 5 are integrally formed, forming an L-shaped structure. A raised surface 21 is provided on the other side of the rotating member 2, through which the mounting hole 8 is formed. The raised surface 21 increases the thickness of the rotating member 2 and enhances the connection strength. The raised surface 21 is triangular or polygonal in shape, enhancing the logo design.
