Description

Technical Field

[0001] This utility model relates to the field of eyewear technology, and in particular to a pair of sunglasses with temple protection. Background Technology

[0002] Sunglasses, also known as sun protection glasses, are used to shield the eyes from the sun. When exposed to sunlight, people typically adjust the size of their pupils to regulate the amount of light entering the eye. When the light intensity exceeds the eye's ability to adjust, it can cause damage. Sunglasses can block uncomfortable glare and protect the eyes from harmful ultraviolet rays.

[0003] When wearing sunglasses, if you temporarily enter a dimly lit indoor place, most wearers tend to hang the sunglasses on their forehead or take them off and hang them in their chest pocket. This leaves the sunglasses unprotected. The most vulnerable part of sunglasses is the hinge connection. If an unexpected external force causes the temples to bend in the opposite direction of folding, the temples can easily break or the hinges can be damaged. This needs to be improved. Utility Model Content

[0004] To address the shortcomings of the aforementioned technologies, this utility model provides sunglasses with temple protection, comprising a frame, a lens assembly, and a pair of temples. The pair of temples are hinged to both ends of the frame. The lens assembly is housed within the frame. Each hinge connection between the temples and the frame is equipped with a reverse-folding protection mechanism. This mechanism includes a buffer support column, a compression spring, and a buffer mounting cylinder. The buffer mounting cylinder is fitted onto the end of the temple. The end of the buffer mounting cylinder has a sliding through hole that matches the buffer support column and has a diameter smaller than the inner wall of the buffer mounting cylinder. One end of the buffer support column is fixed with a sliding stop that matches the inner wall of the buffer mounting cylinder. The sliding stop is located within the buffer mounting cylinder, and the buffer support column is located within the sliding through hole. The compression spring is located within the buffer mounting cylinder, with both ends contacting the sliding stop and the temple, respectively.

[0005] By adopting the above technical solution, a reverse folding protection mechanism is set at the hinge connection between a pair of temples and the frame, including a buffer support column, a compression spring, and a buffer mounting cylinder. The buffer support column is set inside the buffer mounting cylinder and is elastically limited by the compression spring. When the temple is normally opened, one end of the buffer support column will contact the end hinge of the frame, so that the temple stands upright at a normal vertical angle. When the temple is accidentally pried open by an external force, the buffer support column will retract into the buffer mounting cylinder, so that the temple can temporarily unfold outward at a small angle. At the same time, the temple will provide a reset reaction force under the elastic force of the compression spring, so that the temple will immediately return to its original position, avoiding accidental damage to the temple body or the hinge.

[0006] Further features of this invention: The hinge includes a fixed end and a movable end that are rotatably connected. The fixed end is fixedly connected to the frame. The movable end is fixedly provided with a mounting sleeve that matches the buffer mounting sleeve. Both the movable end and the buffer mounting sleeve have mounting through holes. The pair of temples have threaded holes that match the mounting through holes at positions corresponding to the mounting through holes. Connecting screws are provided in the mounting through holes and the threaded holes.

[0007] By adopting the above technical solution, since the hinge includes a fixed end and a movable end that are rotatably connected, the fixed end is fixedly connected to the frame, and the movable end is fixedly provided with a mounting sleeve that matches the buffer mounting sleeve, both the movable end and the buffer mounting sleeve have mounting through holes, and the pair of temples have threaded holes that match the mounting through holes at positions corresponding to the mounting through holes, and connecting screws are provided in the mounting through holes and threaded holes, which can facilitate the disassembly and assembly of the anti-folding protection mechanism.

[0008] A further feature of this invention is that a top contact block is fixedly provided at the end of the buffer support column.

[0009] By adopting the above technical solution, since a top contact block is fixedly provided at the end of the buffer support column, the contact area can be increased by allowing the top contact block to contact the fixed end, so that the temple can stand up more vertically when it is opened.

[0010] A further feature of this invention is that a magnet is embedded in the fixed end at a position corresponding to the top contact block, and the top contact block is made of magnetic material.

[0011] By adopting the above technical solution, since a magnet is embedded at the position corresponding to the top connecting block on the fixed end, and the top connecting block is made of magnetic material, the stability can be improved by the magnet attracting the top connecting block after the temple is opened, thus preventing the temple from rotating randomly and reducing the probability of the temple bending in the opposite direction.

Detailed Implementation

[0018] like Figure 1-5 As shown, a pair of sunglasses with temple protection includes a frame 1, a lens assembly 2, and a pair of temples 3. The pair of temples are connected to both ends of the frame via hinges. The lens assembly is disposed within the frame. Each hinge connection between the pair of temples and the frame is provided with a reverse folding protection mechanism 4. The reverse folding protection mechanism includes a buffer support column 5, a compression spring 6, and a buffer mounting cylinder 7. The buffer mounting cylinder is sleeved on the end of the temple. The end of the buffer mounting cylinder has a sliding through hole 8 that matches the buffer support column and has a diameter smaller than the inner wall of the buffer mounting cylinder. One end of the buffer support column is fixedly provided with a sliding stop 9 that matches the inner wall of the buffer mounting cylinder. The sliding stop is disposed within the buffer mounting cylinder, the buffer support column is disposed within the sliding through hole, and the compression spring is disposed within the buffer mounting cylinder with its two ends contacting the sliding stop and the temple, respectively.

[0019] A reverse folding protection mechanism is installed at the hinge connection between a pair of temples and the frame, including a buffer support column, a compression spring, and a buffer mounting cylinder. The buffer support column is placed inside the buffer mounting cylinder and is elastically limited by the compression spring. When the temple is normally opened, one end of the buffer support column will contact the end hinge of the frame, so that the temple stands upright at a normal vertical angle. When the temple is accidentally pried open by an external force, the buffer support column will retract into the buffer mounting cylinder, allowing the temple to temporarily unfold outward at a small angle. At the same time, the temple will provide a restoring reaction force under the elastic force of the compression spring, so that the temple will immediately return to its original position, avoiding accidental damage to the temple body or the hinge.

[0020] The hinge includes a fixed end 10 and a movable end 11 that are rotatably connected. The fixed end is fixedly connected to the frame. The movable end is fixedly provided with a mounting sleeve 12 that matches the buffer mounting sleeve. Both the movable end and the buffer mounting sleeve have mounting through holes 13. The pair of temples have threaded holes 14 that match the mounting through holes at positions corresponding to the mounting through holes. The mounting through holes and threaded holes are provided with connecting screws 15.

[0021] Since the hinge includes a fixed end and a movable end that are rotatably connected, the fixed end is fixedly connected to the frame, and the movable end is fixedly provided with a mounting sleeve that matches the buffer mounting sleeve, both the movable end and the buffer mounting sleeve have mounting through holes, and the pair of temples have threaded holes that match the mounting through holes at positions corresponding to the mounting through holes, and connecting screws are provided in the mounting through holes and threaded holes, which can facilitate the disassembly and assembly of the anti-folding protection mechanism.

[0022] A top contact block 16 is fixedly provided at the end of the buffer support column.

[0023] Since a top contact block is fixedly provided at the end of the buffer support column, the contact area can be increased by allowing the top contact block to contact the fixed end, so that the temple can stand up more vertically when it is opened.

[0024] A magnet 17 is embedded in the fixed end at a position corresponding to the top contact block, and the top contact block is made of magnetic material.

[0025] Because a magnet is embedded at the position corresponding to the top connecting block on the fixed end, and the top connecting block is made of magnetic material, the stability can be improved by the magnet attracting the top connecting block after the temple is opened, thus preventing the temple from rotating randomly and reducing the probability of the temple bending in the opposite direction.
