Description

Technical Field

[0001] This utility model relates to the field of eyeglass temple flipping, and in particular to a hinged spring temple device. Background Technology

[0002] As a common tool for vision correction or sun protection, eyeglasses typically require hinges to connect the temples to the frame for opening, wearing, and folding. Traditional eyeglass hinges are mostly simple hinge or snap-on types, requiring manual operation for opening and folding the temples, lacking automatic assistance functions, and thus offering insufficient convenience.

[0003] To improve the user experience, some hinge structures with springs have emerged on the market, designed to enable automatic opening of the temples or provide a certain degree of damping. However, existing spring-loaded hinge structures are often quite complex, with numerous components, leading to cumbersome assembly processes, high production costs, and a tendency to loosen or fail after prolonged use due to spring fatigue or component wear, affecting the reliability and durability of the structure. Furthermore, existing hinge designs often lack an effective automatic reset mechanism after the temples are excessively opened in the opposite direction, potentially causing accidental damage to the temples or discomfort when wearing them. Summary of the Invention

[0004] The purpose of this invention is to provide a hinged spring temple device with a clever and simple structure that can promptly limit the movement when the temple is folded back, thus making it suitable for different users. It has good adjustability and applicability, and is efficient and convenient.

[0005] The technical solution to achieve the purpose of this utility model is as follows: This utility model has a frame and temples disposed on both sides of the frame; a rotating assembly is provided between each temple and the frame for automatically folding when the temple is stored or resetting when the temple is opened and folded back. The rotating assembly includes a first mounting groove disposed on the frame, a mounting seat fixedly installed in the first mounting groove, a second mounting groove disposed in the temple, and a rotating seat rotatably disposed in the second mounting groove. The rotating seat is provided with at least one limiting slide rod, and a limiting plate is provided at one end of the limiting slide rod away from the rotating seat. The mounting seat is provided with a mounting boss integrally formed with the mounting seat. The first mounting groove is provided with a mounting recess, and the mounting recess is provided with a limiting plate that corresponds to and allows the limiting slide rod to slide. The mounting boss has a limiting groove corresponding to the limiting slide rod. The bottom of the limiting groove has a connecting through hole coaxial with the limiting groove. The diameter of the connecting through hole is smaller than the diameter of the limiting groove but greater than or equal to the diameter of the limiting slide rod. The limiting slide rod passes through the connecting through hole and extends into the corresponding limiting slide hole, and then slides with the mounting base. A return spring is sleeved on the limiting slide rod. The two ends of the return spring act on the bottom of the limiting plate and the limiting groove, respectively. When the temples are folded and stored, they are automatically folded through the rotational connection with the rotating base, the sliding connection between the limiting slide rod and the mounting base, and the continuous force of the return spring. When the temples are folded backward, they are reset through the pressure of the temples against the mounting base, the sliding connection between the limiting slide rod and the mounting base, and the continuous force of the return spring.

[0006] Furthermore, the second mounting groove is provided with a waist-shaped side mounting groove on its side wall. Each side mounting groove is equipped with a waist-shaped positioning block. Each waist-shaped positioning block is provided with a rotating shaft integrally formed with the waist-shaped positioning block. The rotating seat is provided with rotating holes corresponding to the rotating shaft on both sides. Each temple is rotatably connected to the rotating seat through the cooperation of the rotating shaft and the rotating hole.

[0007] Furthermore, each side mounting groove is provided with a positioning recess, and each waist-shaped positioning block has a positioning protrusion at one end away from the rotating shaft. Each waist-shaped positioning block is positioned and installed in the side mounting groove by the insertion and cooperation of the positioning protrusion and the positioning recess.

[0008] Furthermore, the second mounting groove is provided with a limiting part integrally formed with the temple, and the limiting part is provided with a limiting inclined surface. When the rotating seat is folded back, the folding angle is limited by pressing against the limiting inclined surface.

[0009] Furthermore, the second mounting groove is provided with a side opening, a side mounting plate is provided on the side opening, and a side groove is provided on the side opening. The side mounting groove and the side groove are connected. The side mounting plate is provided with a mounting step corresponding to the side groove. The mounting step is provided with a pressing arc surface that can press the waist-shaped positioning block into the side mounting groove. The side mounting plate is installed and connected to the side opening of the temple through the insertion and cooperation of each mounting step and the side groove. The waist-shaped positioning block is fixedly installed in the side mounting groove by pressing the side of the waist-shaped positioning block with the pressing arc surface.

[0010] Furthermore, the second mounting groove is provided with a corresponding locking groove, and each mounting step is provided with a plastic locking plate corresponding to each locking groove. The side mounting plate is detachably fixed to the temple of the mirror through the insertion and cooperation between the mounting step and the side groove, and the insertion and cooperation between each plastic locking plate and the locking groove.

[0011] This utility model has positive effects: (1) By setting a rotating component between each temple and frame, each temple automatically folds when folded and stored by rotating connection with the rotating seat, sliding connection between the limiting slide rod and the mounting seat, and continuous force of the return spring. When each temple is folded back, it is reset by pressing against the mounting seat, sliding connection between the limiting slide rod and the mounting seat, and continuous force of the return spring. By combining the sliding cooperation between the limiting slide rod and the mounting seat, and the rotation cooperation between the temple and the rotating seat, and utilizing the continuous elasticity of the return spring, the two technical problems of automatic folding when storing the temple and automatic reset when the temple is accidentally folded back after being opened are solved at the same time. When the temple is folded and stored, the self-locking force provided by the return spring causes the temple to automatically close when it is rotated to a certain angle. Similarly, when the temple is folded back, the clamping force provided by the return spring can be used for various head circumferences of different users and is more secure to wear. The structure is ingenious, convenient and practical.

[0012] (2) By setting up a waist-shaped positioning block, the cooperation between the rotating shaft and the rotating hole on the waist-shaped positioning block realizes a reliable and easy-to-assemble rotating connection between the temple and the rotating seat. The structure of the waist-shaped positioning block makes it easy to install and fix in the second mounting groove, providing a foundation for the stable operation of the entire rotating pair, which is stable and practical.

[0013] (3) By setting a positioning recess and a positioning protrusion, this utility model increases the insertion and cooperation between the positioning protrusion and the positioning recess, ensuring that the waist-shaped positioning block is accurately positioned during installation and preventing it from rotating or shifting during use, thereby enhancing the stability and durability of the rotating connection point.

[0014] (4) By setting a limiting part with a limiting slope, this utility model provides a physical mechanical stop for the folding action of the temple, preventing the temple from being damaged by excessive folding and thus playing a protective role and limiting the safe range of motion.

[0015] (5) By setting a pressing arc surface on the installation step, the installation step and the side groove are connected to achieve preliminary positioning and fixation. The pressing arc surface directly applies pressure to the waist-shaped positioning block, which firmly locks it in the side installation groove, eliminating the need for additional screws or glue, simplifying the assembly process, and ensuring that the internal parts do not loosen.

[0016] (6) By setting a plastic locking plate on the installation step, the present invention can hear or feel the locking feedback during assembly, which facilitates assembly quality inspection; on the other hand, when it is necessary to repair or replace internal parts, it can be disassembled relatively easily without damage, which improves the maintainability of the product.
