Description
Technical Field
[0001] The utility model relates to the technical field of glasses, in particular to a hinged structure of temples. Background Art
[0002] As a widely used vision correction tool and fashion accessory, the hinged structure between the temples and frames of glasses is crucial. This structure not only needs to ensure that the temples can open and close smoothly to meet wearing and storage requirements, but also must provide a stable connection to prevent the temples from accidentally loosening or shaking during use, affecting wearing comfort and the life of the glasses.
[0003] The existing technology usually uses hot-melt connection to connect the glasses legs to the hinge structure. This process easily causes the plastic material to melt and overflow, resulting in burrs. In addition, hot-melt connection is an irreversible process. Once the components are damaged or the glasses legs are manually bent outward, the glasses legs will be separated from the hinge structure and cannot be firmly installed again, causing the entire pair of glasses to be scrapped. In addition, the glasses legs and the hinge structure connected by hot-melt connection cannot adjust the extension length of the glasses legs, and the adaptability is low. Utility Model Content
[0004] The purpose of the present invention is to overcome the defects of the prior art, and to provide a hinged structure for the temples of the glasses, which solves the problem that the temples of the glasses and the hinged structure are easily separated after being manually bent.
[0005] The technical solution of the utility model is as follows: a temple hinge structure, comprising a glasses frame and glasses temples, wherein the glasses frame and the glasses temples are movably connected by a connecting structure, wherein the connecting structure comprises a hinge seat and a slingshot shell fixedly arranged with the glasses temples, wherein a hinge column is arranged inside the slingshot shell, wherein the glasses frame and the hinge column are movably connected via the hinge seat, an interference portion is provided on the outer surface of the slingshot shell, and a spring for resetting the slingshot shell is provided inside the slingshot shell;
[0006] The temple is provided with a cavity for inserting the slingshot shell, and the temple cavity is sleeved on the outside of the slingshot shell and fixed by an interference fit;
[0007] A rotation limiting structure is formed between the hinge seat and the end surface of the slingshot shell close to the glasses frame.
[0008] By adopting the above technical solution, the slingshot shell and the hinged column and spring provided therein are used as the connecting structure. After the slingshot shell is axially installed into the eyeglass leg cavity, the interference portion is squeezed and deformed, slides into the eyeglass leg cavity and is stuck inside the cavity, thereby achieving the installation, adjustment and fixation of the eyeglass leg and the connecting structure.
[0009] By arranging a spring for resetting in the slingshot shell, when the glasses legs are bent outward and slide, the glasses legs and the slingshot shell together drive the hinge column to squeeze the spring. At this time, the spring deformation generates a reset elastic force, which can reduce the probability of the slingshot shell sliding outward, and reduce the stress on the connection between the glasses frame and the hinge seat, and reduce the probability of fracture and deformation. In addition, the rotation limit structure between the hinge seat and the slingshot shell can realize the opening and closing of the glasses legs, meeting people's wearing and placement needs.
[0010] The present invention is further configured as follows: the inner side of the interference portion is integrally connected to the surface of the slingshot shell, and the outer side extends obliquely in a direction to prevent the slingshot shell from separating from the glasses leg, and the interference portion is in clamping contact with the inner wall of the glasses leg cavity.
[0011] With the above further arrangement, the outer side of the interference portion extends obliquely outward, and the direction is limited to prevent the slingshot shell from separating from the glasses leg, so that the glasses leg and the slingshot shell are more stable after installation and are not easy to fall off, and its oblique direction does not affect the installation.
[0012] The present invention is further configured as follows: the hinge seat includes a fixed end fixed to the glasses frame; the glasses frame is provided with a mounting groove, and the fixed end extends into the mounting groove for fixed connection.
[0013] By adopting the above-mentioned further arrangement, the hinge seat is inserted into the mounting groove through the movable end and then fixedly connected, so as to achieve a close fit between the hinge seat and the mounting groove, thereby avoiding burrs or overflow caused by the hot-melt connection between the hinge seat and the eyeglass frame in the original process, thereby ensuring the quality of the product.
[0014] The present invention is further configured as follows: the hinge seat further includes a movable end, one end of the hinge column extends out of the slingshot housing and is hinged to the movable end, and the spring is sleeved on the outer wall of the hinge column inside the slingshot housing.
[0015] By further adopting the above arrangement, the hinge column is hinged to the hinge seat instead of the slingshot shell and the hinge seat, so that when the hinge column with the spring is displaced from the slingshot shell, it can squeeze the spring to generate elastic force and then reset.
[0016] The present invention is further configured as follows: a pressing portion is sleeved on the outer wall of the hinge column, the pressing portion is clamped and fixed to the inner wall of the slingshot shell, the pressing portion slides relative to the hinge column, one end of the spring presses against the pressing portion, and the other end of the spring is fixed relative to the hinge column.
[0017] With the above-mentioned further arrangement, the pressing portion is clamped on the inner wall of the slingshot shell, and the pressing portion is sleeved on the outside of the hinge column. Therefore, when the slingshot shell is subjected to force, the pressing portion is driven to move, and the pressing portion presses the spring to move on the hinge column, thereby realizing the extrusion deformation of the spring, causing it to generate a restoring elastic force, offsetting the external force that causes the slingshot shell and the hinge column to slide relative to each other, and reducing the possibility of the slingshot shell sliding off the hinge column.
[0018] The present invention is further configured as follows: the rotation limiting structure includes a limiting portion protruding outward from the bottom end surface of the slingshot shell and a limiting groove corresponding to the limiting portion and opened on the top end surface of the movable end; a circular arc chamfer is formed between the side of the limiting groove and the top end surface of the movable end to prevent the limiting portion from rotating.
[0019] By adopting the above-mentioned further arrangement, the limiting part and the limiting groove are arranged so that after the glasses leg is rotated, the bottom surface of the limiting part can contact the bottom surface of the limiting groove to achieve opening limit. When the glasses leg is rotated and closed, the side wall of the limiting part contacts the top end surface of the movable end to limit the position, preventing the glasses leg from rotating excessively, thereby achieving rotation limit in two directions of the glasses leg.
[0020] The present invention is further configured as follows: the installation groove is an oblique groove, the inner wall of which is tightly fitted with the fixed end of the hinge seat, and the oblique groove is in a T-shaped structure as a whole.
[0021] With the above-mentioned further arrangement, the design of the inclined groove enables the installation groove to be tightly fitted after insertion, and suppresses the movement between the hinge seat and the eyeglass frame. The inclined groove is further designed as a T-shaped structure, which can increase the contact area between the hinge seat and the installation groove and enhance the stability of the fixed fit.
[0022] The present invention is further configured such that a bolt assembly is passed through the fixed end of the hinged seat and the mounting groove for fixing.
[0023] With the above arrangement further taken forward, a threaded connection is formed by an assembly of a bolt and a nut or a bolt and a thread provided on the hinge seat, thereby achieving fixation of the hinge seat and the eyeglass frame.
[0024] The present invention is further provided with the following configuration: the material of the glasses frame and the glasses legs is plastic.
[0025] With the above-mentioned further configuration, the plastic material is soft in texture, lightweight, elastic, can automatically recover after deformation, and can be injection molded, which is lower in cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that technical personnel in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.
[0035] like Figure 1-4 As shown, a temple hinge structure includes a glasses frame 1 and a glasses leg 2, wherein the glasses frame 1 and the glasses leg 2 are movably connected by a connecting structure, and the connecting structure includes a slingshot shell 8 fixed to the glasses leg 2 and a hinge seat 4 for hingedly connecting the slingshot shell 8 and the glasses frame 1.
[0036] The outer surface of the slingshot shell 8 is protruding with an interference portion 9, and the eyeglass leg 2 is provided with a cavity for inserting the slingshot shell 8. The cavity of the eyeglass leg 2 is sleeved on the outside of the slingshot shell 8 and fixed by the interference portion 9. The interference portion 9 serves as an elastic snap structure, the inner side of which is integrally connected to the surface of the slingshot shell 8, and the outer side extends obliquely in the direction of preventing the slingshot shell 8 from separating from the eyeglass leg 2. The interference portion 9 is in clamping contact with the inner wall of the cavity of the eyeglass leg 2, and the outer side of the interference portion extends obliquely outward, and the direction is limited to the direction of preventing the slingshot shell 8 from separating from the eyeglass leg 2, so that the eyeglass leg and the slingshot shell are more stable after installation, thereby achieving the effect of low assembly force and high tensile strength, making the eyeglass leg 2 and the slingshot shell 8 easy to install, disassemble and adjust, more stable during installation and not easy to fall out, and its oblique direction does not affect the installation.
[0037] It should be noted that the slingshot shell 8 can be a rectangular column structure or a cylindrical structure, and the interference portion 9 can be an annular structure surrounding the outer wall of the slingshot shell 8, or can be a plurality of block structures symmetrically distributed around the axis center of the slingshot shell 8.
[0038] A hinge column 6 is provided inside the slingshot shell 8, and the two can move relative to each other. One end of the hinge column 6 extends out of the slingshot shell 8, and a spring 7 is provided on the outer sleeve of the hinge column 6 in the internal cavity of the slingshot shell 8. By arranging the hinge column 6 and the spring 7 in the slingshot shell 8, when the glasses leg 2 is forced to bend outward, the hinge column 6 can be driven to squeeze the spring 7, so that it generates elastic force as a reaction force to balance the outward pulling force, thereby achieving reset.
[0039] Furthermore, a pressing portion 10 is sleeved on the outer wall of the hinge column 6. The pressing portion 10 is a circular ring structure, and its outer surface is clamped and fixed to the inner wall of the slingshot shell 8. The inner surface of the pressing portion 10 slides relative to the hinge column 6. One end of the spring 7 rests on the pressing portion 10, and the other end of the spring 7 is fixed to the hinge column 6, preferably fixedly connected to the top of the hinge column 6. Since the pressing portion 10 is clamped and fixed to the inner wall of the slingshot shell 8, and the pressing portion 10 is sleeved on the outside of the hinge column 6, it can slide along the axial direction of the hinge column 6. Therefore, after the slingshot shell 8 is subjected to force, the pressing portion 10 is driven to move, and the pressing portion 10 presses the spring 7 to move on the hinge column 6, thereby realizing the extrusion deformation of the spring 7, causing it to generate a reset elastic force, offsetting the force that causes the slingshot shell 8 and the hinge column 6 to slide relative to each other, and reducing the possibility of the slingshot shell 8 slipping out on the hinge column 6.
[0040] The hinge seat 4 includes a fixed end 41 fixed to the eyeglass frame 1 and a movable end 42 hinged to the hinge column 6. A mounting groove 3 is provided on the eyeglass frame 1. The fixed end 41 is inserted into the mounting groove 3 and fixedly connected by a bolt assembly 5. Furthermore, the mounting groove 3 is an oblique groove, and its inner wall is tightly fitted with the fixed end 41 of the hinge seat 4, so that the mounting groove 3 can be tightly fitted after insertion, and the movement of the hinge seat and the eyeglass frame is suppressed. Furthermore, the mounting groove 3 can be an oblique groove with a T-shaped structure, which can increase the contact area between the hinge seat and the mounting groove 3 and make the fixed fit more stable.
[0041] It should be noted that the bolt assembly can be a bolt and a nut, or a bolt and a thread provided on the hinge seat 4, which can form a threaded connection, thereby achieving the fixation of the hinge seat 4 and the eyeglass frame 1.
[0042] A rotation limiting structure is formed between the movable end 42 of the hinge seat 4 and the end face of the slingshot shell 8 close to the eyeglass frame 1; the rotation limiting structure includes a limiting portion 81 protruding outward from the bottom end face of the slingshot shell 8 and a limiting groove 43 corresponding to the limiting portion 81 and opened on the top end face of the movable end 42, and a circular arc chamfer is formed between the side of the limiting groove 43 and the top end face of the movable end 42 to avoid the rotation of the limiting portion 81; through the arrangement of the limiting portion 81 and the limiting groove 43, after the eyeglass leg 2 is rotated, the bottom face of the limiting portion 81 can contact the bottom face of the limiting groove 43 to realize the opening limit, and when the eyeglass leg 2 is rotated and closed, the side wall of the limiting portion 81 contacts the top end face of the movable end 42 to prevent the eyeglass leg from rotating excessively, thereby realizing the rotation limit of the eyeglass leg in two directions.
[0043] Specifically, the slingshot shell 8 is axially inserted into the cavity of the eyeglass leg 2. At this time, the elastic interference portion 9 with an inclined structure is squeezed and deformed, slides into the cavity of the eyeglass leg 2, and is stuck inside the cavity, thereby achieving the effect of quick installation and adjustment of the eyeglass leg 2.
[0044] The hinge seat 4 is inserted into the mounting groove 3 through the movable end 42 and is fixedly connected, so that the hinge seat 4 and the mounting groove 3 are tightly matched, which can avoid burrs or overflow caused by the hot-melt connection between the hinge seat 4 and the eyeglass frame 1 in the original process, thereby ensuring the quality of the product. In addition, the rotation limiting structure between the movable end 42 and the slingshot shell 8 can realize the opening and closing of the eyeglass legs, meeting people's wearing and placement needs.
[0045] The material of the glasses frame 1 and the glasses legs 2 is plastic. The plastic material is soft, light, elastic, can automatically recover after deformation, and can be injection molded, which is lower in cost.
