Description

Technical Field

[0001] This utility model belongs to the field of eyeglasses processing technology, specifically relating to a connection structure between the temple and the frame. Background Technology

[0002] Eyeglasses generally consist of temples, frames, and lenses. The frame has a nose pad in the middle, and the edges of the frame are connected to the temples via posts. A rotatable connection structure, usually a hinge, is provided at the connection between the posts and the temples.

[0003] Traditional eyeglasses (e.g., publication number: CN 222365147 U) have foldable hinge mechanisms on the temples. These hinge mechanisms only have one-way limiting, that is, the limiting when the temples open outwards. When wearing them, the glasses need to fit the head and face. The opposing force of the inward clamping force on the face from the temples helps to keep the glasses stable. However, wearing them for a long time can easily cause pressure and fatigue on the face, affecting the user's comfort and stability. Further improvements are necessary. Utility Model Content

[0004] The purpose of this invention is to provide a connection structure between the temple and the frame to solve the problem of eyeglasses causing fatigue and affecting the comfort and stability of the user.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A temple and frame connection structure for connecting the temple and frame includes a double hinge head integrally disposed at the end of the temple head and a hinge pin integrally disposed at the end of the temple. The rotation axis of the double hinge head and the hinge pin is configured as a stud screwed into and threadedly connected to the double hinge head. A limiting notch is formed at the end of the temple head, and a connecting shell is fixedly installed on the limiting notch. Limiting blocks are symmetrically installed in the connecting shell through a connecting rod assembly. A hinge pin limiting section is integrally disposed at the end of the temple, and auxiliary limiting sections extend to the upper and lower sides of the hinge pin limiting section. A guide groove is formed in the limiting notch, and a stop block connected to the connecting rod assembly is slidably connected in the guide groove. When the temple is opened, the end of the hinge pin limiting section abuts against the stop block, and the connecting rod assembly drives the limiting block to move to the upper and lower sides of the connecting shell, so that the limiting block engages with the auxiliary limiting section.

[0007] In this application, when a user wears glasses, there is pressure on the temples of the glasses from the face, keeping the temples clamped on both sides of the head. At this time, the temples of the glasses are in the open state. The end of the hinge pin limiting section presses against the abutment block. The limiting block engages with the auxiliary limiting section, which can prevent the temples from folding or improve the stability of the temples in the open state. It also assists in the outward pressure of the face, thereby reducing the external support force of the face on the temples, relieving facial fatigue, and improving the comfort and stability of wearing glasses. It is highly practical.

[0008] Furthermore, the auxiliary limiting section is a corrugated section, and the outer side of the limiting block is a recessed section that cooperates with the auxiliary limiting section.

[0009] The corrugated section can provide a limiting groove or notch, and can also be distinguished from conventional bars, thus improving the aesthetics of the temples.

[0010] Furthermore, the linkage assembly includes a connecting rod, an adjusting rod, and a push rod. One end of the connecting rod is connected to the limiting block, and the other end of the connecting rod is connected to the connecting shell. One end of the push rod is connected to the abutment block, and the other end of the push rod is set as a free end. The adjusting rod is connected between the connecting rod and the push rod.

[0011] Furthermore, a spring is fitted onto the free end of the push rod, and the spring is disposed within the guide groove; a limiting protrusion is provided at the end of the guide groove near the temple. The spring can provide an extension force, causing the push rod and the stop block to tend to move towards the hinge pin limiting section.

[0012] Furthermore, the upper and lower edges of the limiting notch are provided with locking protrusions for limiting the outer side of the auxiliary limiting segment.

[0013] Furthermore, a rubber sleeve is provided at the end of the auxiliary limiting section.

[0014] The utility model adopting the above technical solution has the following advantages:

[0015] In this application, when the user opens and wears the temples, the end of the hinge pin limiting section approaches and presses against the abutment block, causing the abutment block to move towards the post head within the guide groove. The abutment block, through the connecting rod assembly, drives the two limiting blocks to move to the upper and lower sides of the connecting shell respectively, so that the limiting blocks engage with the corresponding surfaces of the synchronously moving auxiliary limiting sections. In this way, this engagement method can prevent the temples from folding, which is equivalent to applying a pulling force to the temples. At the same time, after the user wears the glasses, there is a compression of the temples by the face or head. Keeping the temples clamped on both sides of the head, the engagement of the limiting blocks with the auxiliary limiting sections and the clamping of the temples can prevent the temples from folding, improve the stability of the temples in the open state, help reduce the external support force of the face on the temples, relieve facial fatigue, improve wearing comfort and stability, and has high practicality.

Detailed Implementation

[0028] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. Furthermore, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0029] like Figures 1-9 As shown in the figure, a temple and frame connection structure 300 of this utility model is used to connect the stud 200 of the frame and the temple 100. The connection structure 300 includes a double hinge head 201 integrally disposed at the end of the stud head 200 and a hinge pin integrally disposed at the end of the temple 100. The stud head 200 is generally welded to the end of the frame. The rotation axis of the double hinge head 201 and the hinge pin is set as a stud 202 that is screwed into the double hinge head 201 and threadedly connected to the double hinge head 201. A limiting notch 203 is provided at the end of the stud head 200, and the limiting notch 203 is welded to it. A connecting shell 301 is fixedly installed, and limit blocks 302 are symmetrically installed inside the connecting shell 301 via a connecting rod assembly; a hinge pin limiting section 102 is integrally provided at the end of the temple 100, and an anti-slip sleeve 101 is fitted on the free end of the temple 100. The anti-slip sleeve 101 is made of transparent silicone; auxiliary limiting sections 103 are provided on the upper and lower sides of the hinge pin limiting section 102; the temple 100, the hinge pin limiting section 102, and the auxiliary limiting section 103 are integrally formed, made of the same material, have the same hardness, are not easily deformed under normal conditions, and will return to their original shape even if deformed. A guide groove 204 is provided within the limiting notch 203, and a stop block 305 connected to the connecting rod assembly is slidably connected within the guide groove 204. When the temple 100 is opened, under the rotational relationship of the double hinge head 201 and the hinge pin, the temple 100 can be opened from the folded state. The end of the hinge pin limiting section 102 presses against the stop block 305, and the connecting rod assembly drives the limiting block 302 to move up and down to both sides of the connecting shell 301, so that the limiting block 302 engages with the auxiliary limiting section 103. The auxiliary limiting section 103 is a corrugated section, and the outer side of the limiting block 302 is a recessed section that cooperates with the auxiliary limiting section 103. It can be understood that when the temple 100 is in the folded state, the limiting block 302 is retracted into the connecting shell 301 and is not visible, while the stop block 305 extends out of the connecting shell 301; the overall appearance is relatively simple and beautiful.

[0030] In this embodiment, after the user wears the glasses, the pressure of the face on the temples 100 causes the end of the hinge pin limiting section 102 to always press against the abutment block 305, keeping the temples 100 clamped on both sides of the head. At this time, the glasses are in the open state. The end of the hinge pin limiting section 102 pressing against the abutment block 305 causes the limiting block 302 to engage with the auxiliary limiting section 103, which can prevent the temples 100 from folding, improve the stability of the temples 100 in the open state, reduce the outward pressure required by the face, thereby reducing the external support force of the face on the temples 100, relieving facial fatigue, and improving wearing comfort and stability, making it highly practical. The corrugated section design can provide a groove or notch to engage with the end of the limiting block 302, as well as an outward convex surface to engage with the recessed section; it can also be distinguished from conventional rods, improving the appearance of the temples 100, thereby improving the overall aesthetics of the glasses.

[0031] In this embodiment, the linkage assembly includes a connecting rod 303, an adjusting rod 304, and a push rod 306. One end of the connecting rod 303 is connected to the limiting block 302, specifically, it can be hinged by a pin hole connection. The other end of the connecting rod 303 is rotatably connected to a positioning post on the inner surface of the connecting shell 301. One end of the push rod 306 is connected to the abutment block 305, and the other end of the push rod 306 is set as a free end. A spring 308 is sleeved on the free end of the push rod 306, and the spring 308 is set in the guide groove. Inside 204; a limiting protrusion is provided at one end of the guide groove 204 near the temple 100, which can prevent the abutment 305 from falling out of the guide groove 204; the adjusting rod 304 is connected between the connecting rod 303 and the push rod 306. Specifically, a connecting shaft is provided in the middle section of the connecting rod 303, and a connecting hole is opened on the push rod, into which a hinge shaft 307 is inserted; one end of the adjusting rod 304 is hinged to the connecting shaft, and the other end of the adjusting rod 304 is hinged to the hinge shaft 307.

[0032] The spring 308 can provide an extension force, causing the push rod 306 and the stop block 305 to tend to move toward the hinge pin limiting section 102; the guide groove 204 restricts the movement direction of the push rod 306 and the stop block 305, and the limiting protrusion restricts the maximum stroke of the stop block 305.

[0033] In fact, in this embodiment, a telescopic spring can also be used instead of the adjusting rod 304 to improve the flexibility of the limiting block 302.

[0034] In this embodiment, the upper and lower edges of the limiting notch 203 are provided with locking protrusions to limit the outer side of the auxiliary limiting segment 103. Thus, the combination of the locking protrusions and the limiting block 302 improves the limiting stability of the auxiliary limiting segment 103, thereby improving the clamping stability of the temple 100. Furthermore, when the user applies a certain external force, the limiting block 302 can release the limiting of the auxiliary limiting segment 103 without affecting the folding of the temple 100.

[0035] In fact, a rubber sleeve is provided at the end of the auxiliary limiting section 103; the rubber sleeve can abut against the side wall of the limiting notch 203 to provide a certain buffering force; in addition, the rubber sleeve can be set as a glow-in-the-dark sleeve to increase the personalized customization of the glasses.

[0036] This embodiment provides a temple and frame connection structure. When a user wears glasses, their face or head exerts pressure on the temple 100. The temple 100 is kept clamped on both sides of the head. The engagement of the limiting block 302 and the auxiliary limiting segment 103 assists in clamping the temple 100, preventing it from folding, improving its stability in the open state, reducing the external force exerted by the face on the temple 100, alleviating facial fatigue, and improving wearing comfort and stability. It is highly practical.

[0037] The foregoing has provided a detailed description of a temple and frame connection structure for eyeglasses provided by this utility model. The specific embodiments described are merely for the purpose of helping to understand the method and core concept of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
