Description

Technical Field

[0001] This utility model belongs to the field of eyeglasses technology and relates to eyeglasses with rotatable temples. Background Technology

[0002] Eyeglasses are simple optical devices made to correct vision or protect the eyes. They consist of lenses and frames. There are four main types of eyeglasses for vision correction: nearsightedness glasses, farsightedness glasses, reading glasses, and astigmatism glasses. Other types include safety goggles, sunglasses, swimming goggles, etc., providing various forms of eye protection. The temples of eyeglasses are hinged to the frame, allowing them to fold for easy storage. As described in Chinese Patent No. 201621481600.5, a pair of glasses with rotatable temples has the following structure: it includes temples, a frame, and lenses, and a connector between the temples and the frame. The connector includes a pivot, one end of which is rotatably connected to the temple along an axis perpendicular to the pivot, and the other end of which is rotatably connected to the frame along the pivot axis. A U-shaped temple folding groove is provided at the end of the temple connected to the frame, and a temple limiting plate is slidably disposed within the temple folding groove to control the rotation angle of the temple. The temple limiting plate abuts against the connector, restricting the temple from continuing to rotate outward, maintaining tension between the two temples, clamping the head, and maintaining stability. In the above structure, the angle of rotation between the temples and the frame is limited, which cannot well adapt to the user's face shape, resulting in discomfort. Furthermore, when the user has a large face, the temples need to be forcibly pried open during the process of putting on the glasses, which can easily lead to breakage. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing eyeglasses with temples that can be rotated and positioned with a large temple rotation angle.

[0004] The objective of this utility model can be achieved through the following technical solution: a pair of eyeglasses with rotatable temples, comprising a frame and first temples located on both sides of the frame. Each end of the frame is provided with a connecting protrusion. The connecting protrusion includes a first positioning plane, a second positioning plane, a compression arc surface, and a compression angle located between the first positioning plane and the second positioning plane. The end of each first temple is hinged to the connecting protrusion. A spring groove is formed at the end of each first temple. A spring and a pressure block are provided in the spring groove. One end of the pressure block contacts the connecting protrusion, and the other end of the pressure block is movably located within the spring groove. Both ends of the spring contact the bottom of the spring groove and the pressure block, respectively.

[0005] In the aforementioned eyeglasses with rotatable temples, the spring is in an extended state when the pressure block contacts the first positioning plane or the second positioning plane; the spring is compressed when the pressure block contacts the compression angle or the compression arc surface.

[0006] The aforementioned eyeglasses with rotatable temples also include a second temple, the end of which is hinged to the end of the first temple.

[0007] In the aforementioned eyeglasses with rotatable temples, the frame includes two frames and a connector located between the two frames, with both ends of the connector hinged to the two frames respectively.

[0008] In the above-mentioned eyeglasses with rotatable temples, two mounting protrusions are formed at the end of the first temple, and a connecting protrusion is located between the two mounting protrusions. A pin is used to hinge the mounting protrusion and the connecting protrusion.

[0009] Compared to existing technologies, this rotatable temple positioning glasses feature a compression arc surface that allows the first temple to continue rotating outward from its open state. The rotation angle of the first temple is close to the frame, and a large rotation angle facilitates the outward expansion of the first temple during wear, preventing breakage. Simultaneously, a first positioning plane positions the first temple in its open state. When the first temple loses its outward rotation force, the spring releases, causing the first temple to close towards the open state, ensuring it fits snugly against the wearer's face and guaranteeing a stable and reliable fit. A second positioning plane positions the first temple in its retracted state, preventing accidental opening. When the glasses need to be stored and taken out, the second temple is folded together with the first temple, then the first temple is folded relative to the frame, and finally the two frames are folded together, placing the two sets of folded temples between the two frames. This significantly reduces the size of the glasses when stored, making them easy to carry. Attached Figure Description

[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] like Figure 1-5 As shown, this rotatable eyeglass temple includes a frame 1 and first temples 2 located on both sides of the frame 1. Both ends of the frame 1 are provided with connecting protrusions 11, each including a first positioning plane 12, a second positioning plane 13, a compression arc surface 14, and a compression angle 15 located between the first positioning plane 12 and the second positioning plane 13. The ends of the first temples 2 are hinged to the connecting protrusions 11. A spring groove 21 is formed at the end of the first temple 2, containing a spring 3 and a pressure block 4. One end of the pressure block 4 contacts the connecting protrusion 11, and the other end of the pressure block 4 is movably located within the spring groove 21. Both ends of the spring 3 contact the bottom of the spring groove 21 and the pressure block 4, respectively. When the pressure block 4 contacts the first positioning plane 12 or the second positioning plane 13, the spring 3 is in an extended state; when the pressure block 4 contacts the compression angle 15 or the compression arc surface 14, the spring 3 is compressed.

[0018] When the first temple 2 rotates until the end face of the pressure block 4 contacts the first positioning plane 12, the spring 3 is in an extended state, and the first temple 2 is positioned in the open state. When the first temple 2 rotates until the end face of the pressure block 4 contacts the second positioning plane 13, the spring 3 is in an extended state, and the first temple 2 is positioned in the retracted state. When the first temple 2 rotates between the open and retracted states, the compression angle 15 on the connecting protrusion 11 compresses the pressure block 4, and the spring 3 is compressed. When the first temple 2 continues to rotate outward relative to the open state, the compression arc surface 14 compresses the pressure block 4, and the spring 3 is compressed. When the first temple 2 loses the power to continue rotating outward, the spring 3 releases its elasticity, causing the first temple 2 to move closer to the open state, ensuring that the first temple 2 can fit against the wearer's face and ensuring that the glasses are worn stably and reliably.

[0019] The above technical solution also includes a second temple 6, the end of which is hinged to the end of the first temple 2. The frame 1 includes two frame bodies 16 and a connector 17 located between the two frame bodies 16, with both ends of the connector 17 hinged to the two frame bodies 16 respectively. When the glasses need to be stored and carried out, the second temple 6 is folded together with the first temple 2, then the first temple 2 is folded relative to the frame 1, and finally the two frame bodies 16 are folded relative to each other, so that the two sets of folded temples are located between the two frame bodies 16. At this time, the volume of the stored glasses is greatly reduced, making it convenient to carry out.

[0020] In the above technical solution: two mounting protrusions 22 are formed at the end of the first temple 2, the connecting protrusion 11 is located between the two mounting protrusions 22, and the pin is used to hinge the mounting protrusions 22 and the connecting protrusion 11.

[0021] This pair of glasses with rotatable temples utilizes a compression arc surface 14 to allow the first temple 2 to continue rotating outward from its open state. The rotation angle of the first temple 2 is close to 180 degrees, which facilitates the outward opening of the first temple 2 during wear and prevents it from breaking. Simultaneously, a first positioning plane 12 positions the first temple 2 in its open state. When the first temple 2 loses its outward rotation force, the spring 3 releases its elasticity, causing the first temple 2 to close towards the open state, ensuring it fits snugly against the wearer's face and guaranteeing a stable and reliable fit. A second positioning plane 13 positions the first temple 2 in its retracted state, preventing accidental opening when retracted. When the glasses need to be retracted and taken out, the second temple 6 is folded together with the first temple 2, then the first temple 2 is folded relative to the frame 1, and finally the two frame bodies 16 are folded together, placing the two sets of folded temples between the two frame bodies 16. This significantly reduces the size of the glasses when retracted, making them easier to carry.
