Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, and in particular to an eyeglass temple with a large outward flare angle. Background Technology

[0002] Traditional eyeglasses typically have temples connected to the frame via hinges, which limit their range of motion. They can generally only fold inwards about 90 degrees. In actual use, eyeglasses are easily subjected to accidental pressure, such as being pressed down while sleeping or accidentally sitting on them. In these situations, the temples cannot swing outwards, causing stress to concentrate at the hinges. This can easily lead to the temples or hinges breaking or being damaged. At the same time, the outward angle of traditional temples is fixed, making them unsuitable for users with different head shapes. Utility Model Content

[0003] The present invention aims to solve the existing technical problem by providing a pair of eyeglass temples with a large outward flare angle. These temples can not only fold inward normally, but also swing outward at a large angle, thereby swinging to relieve force when accidentally pressed, effectively preventing breakage or damage.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: This utility model discloses a pair of eyeglass temples with a large outward flare angle, including a temple body and a temple flap located at the left end of the temple body. The temple flap has a head flap on its left side. Symmetrical baffles are provided on both the front and rear sides of the left end of the temple flap. A rotating head is located in the middle of the right end face of the head flap, positioned between the front and rear baffles. The rotating head is hinged to the front and rear baffles via a hinge structure. A right limiting plane is present on the right end face of the rotating head. An upper limiting plane is present on the upper surface of the rotating head. A lower limiting plane is present on the lower surface of the rotating head. The right end of the limiting plane is connected to the upper end of the right limiting plane by an upper arc surface; the right end of the lower limiting plane is connected to the lower end of the right limiting plane by a lower arc surface; the arc of the upper arc surface is greater than the arc of the lower arc surface; a telescopic hole is provided at the center of the left end face of the temple; a matching pressure shaft is provided in the left end opening of the telescopic hole, and the left end of the pressure shaft extends to the left to the outside of the telescopic hole and presses against the right limiting plane; a spring is provided between the right end face of the pressure shaft and the bottom of the telescopic hole; there is a rotational distance between the right limiting plane and the left end face of the temple.

[0005] A groove is provided in the middle of the right limiting plane; the width of the groove opening on the right side is smaller than the diameter of the pressure shaft.

[0006] The hinge structure includes a hinge hole on the rotating head; the front baffle is provided with a screw hole coaxial with the hinge hole, and the rear baffle is provided with a countersunk hole coaxial with the hinge hole; a hinge screw passes forward through the countersunk hole and the hinge hole in sequence and is screwed into the screw hole.

[0007] A locking hole is provided at the center of the right end face of the pressure shaft, and the left end of the spring is locked in the locking hole.

[0008] The left inner wall of the telescopic hole is provided with an annular limiting step, which is located on the right side of the pressure shaft; the diameter of the pressure shaft is larger than the inner diameter of the limiting step.

[0009] This utility model has the following beneficial effects: Compared with the prior art, the eyeglass temples with a large outward opening angle using the structure of this utility model can simultaneously swing upward and downward by about 90 degrees through the cooperation of the right limiting plane, the upper limiting plane, the lower limiting plane, the pressure shaft, and the spring. When the eyeglasses are actually in use, once subjected to external force, the temples can fold inward by about 90 degrees or open outward by about 90 degrees. When the temples open outward by about 90 degrees, the temples are almost on the same plane as the frame, allowing the temples to obtain a large outward opening angle. This allows them to swing and relieve force when accidentally pressed, effectively avoiding stress concentration that could lead to breakage of the temples or hinges. Attached Figure Description

Detailed Implementation

[0011] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Please see Figures 1 to 3This utility model provides a pair of eyeglass temples with a large outward flare angle, including a temple body 1 and a temple panel 2 located at the left end of the temple body 1. The temple panel 2 has a head panel 3 on its left side. Symmetrical baffles 4 are provided on the front and rear sides of the left end of the temple panel 2. A rotating head 5 is located between the front and rear baffles 4 at the center of the right end of the head panel 3. The rotating head 5 is hinged to the front and rear baffles 4 through a hinge structure. A right limiting plane 6 is provided on the right end of the rotating head 5. An upper limiting plane 7 is provided on the upper surface of the rotating head 5. A lower limiting plane 8 is provided on the lower surface of the rotating head 5. The upper limiting plane 7 is right... The upper end of the right limiting plane 6 is connected to the lower end of the right limiting plane 8 by an upper arc surface 9; the lower end of the right limiting plane 8 is connected to the lower end of the right limiting plane 6 by a lower arc surface 10; the arc of the upper arc surface 9 is greater than the arc of the lower arc surface 10; a telescopic hole 11 is provided at the center of the left end face of the temple 2; a matching pressure shaft 12 is provided in the left end opening of the telescopic hole 11, and the left end of the pressure shaft 12 extends to the left to the outside of the telescopic hole 11 and presses against the right limiting plane 6; a spring 13 is provided between the right end face of the pressure shaft 12 and the bottom of the telescopic hole 11; there is a rotational distance 14 between the right limiting plane 6 and the left end face of the temple 2.

[0012] A groove 15 is provided in the middle of the right limiting plane 6; the width of the groove opening on the right side of the groove 15 is smaller than the diameter of the pressure shaft 12.

[0013] The hinge structure includes a hinge hole 16 on the rotating head 5; the front baffle 4 is provided with a screw hole 17 coaxial with the hinge hole 16, and the rear baffle 4 is provided with a countersunk hole 18 coaxial with the hinge hole 16; a hinge screw 19 passes forward through the countersunk hole 18 and the hinge hole 16 in sequence and is screwed into the screw hole 17.

[0014] The pressure shaft 12 has a locking hole 20 at the center of its right end face, and the left end of the spring 13 is locked in the locking hole 20.

[0015] The left inner wall of the telescopic hole 11 is provided with an annular limiting step 21, which is located on the right side of the pressure shaft 12; the diameter of the pressure shaft 12 is larger than the inner diameter of the limiting step 21.

[0016] The method of using this utility model is as follows: Spring 13 can apply pressure through the pressure axis rotating head 5, so that the left end of pressure axis 12 is pressed tightly against the right limit plane of rotating head 5. At this time, the temple 2 cannot swing up and down at will, and the state is stable, which is suitable for normal wearing.

[0017] When the temple is subjected to an upward external force, the temple 2 rotates upward. At this time, the left end of the pressure shaft that was originally pressing against the right limit plane 6 will slide to the upper limit plane 7 through the upper arc surface 9. During this sliding process, the pressure shaft 12 will compress the spring 13, providing space and buffer for the temple to swing upward, so that the temple can swing upward about 90 degrees.

[0018] When the temple is subjected to a downward external force, the temple page 2 rotates downward. At this time, the left end of the pressure shaft 12, which was originally pressing against the right limit plane 6, will slide through the lower arc surface 10 to the lower limit plane 8. During this sliding process, the pressure shaft 12 will also compress the spring, providing space and buffer for the temple to swing downward, so that the temple can swing downward by about 90 degrees.

[0019] In summary, this invention, through the cooperation of the right limiting plane 6, the upper limiting plane 7, the lower limiting plane 8, the pressure shaft 12, and the spring 13, enables the temples to swing upwards and downwards by approximately 90 degrees simultaneously. When the glasses are actually in use, once subjected to external force, the temples can fold inwards by approximately 90 degrees or open outwards by approximately 90 degrees. When the temples open outwards by approximately 90 degrees, the temples are almost on the same plane as the frame, allowing the temples to obtain a large outward opening angle. This enables them to swing and relieve force when accidentally pressed, effectively preventing stress concentration that could lead to temple or hinge breakage.

[0020] A groove 15 is provided in the middle of the right limiting plane 6. The width of the groove opening on the right side of the groove 15 is smaller than the diameter of the pressure shaft 12. The presence of the groove 15 can effectively reduce the actual contact area between the right limiting plane 6 and the left end face of the pressure shaft 12, thereby reducing the actual friction area between the two and further ensuring the smoothness of the rotating head 5 when it rotates.

[0021] The hinge structure includes a hinge hole 16 on the rotating head 5, a screw hole 17 coaxial with the hinge hole on the front baffle 4, and a countersunk hole 18 coaxial with the hinge hole 16 on the rear baffle 4. A hinge screw 19 passes forward through the countersunk hole 18 and the hinge hole 16 in sequence and is screwed into the screw hole 17. This hinge method can not only ensure the stability during hinge, but also facilitate the disassembly of various components.

[0022] A locking hole 20 is provided at the center of the right end face of the pressure shaft 12. The left end of the spring 13 is locked in the locking hole 20. This structure can effectively ensure the stability of the left end of the spring 13, thereby ensuring the stability of the spring 13 when it is pressed on the rotating head 5 by the pressure shaft 12. At the same time, it can reduce the amplitude of the swing of the head 3 caused by the gap between the pressure shaft 12 and the telescopic hole 11.

[0023] The left inner wall of the telescopic hole 11 is provided with a ring-shaped limiting step 21. The limiting step 21 is located on the right side of the pressure shaft 12. The diameter of the pressure shaft 12 is larger than the inner diameter of the limiting step 21. The existence of the limiting step 21 can effectively limit the stroke of the pressure shaft 12 when it retracts inward into the telescopic hole 11, thereby avoiding the situation where the spring 13 is frequently compressed to the limit, which would shorten the life of the spring 13.

[0024] The curvature of the upper arc surface 9 is greater than that of the lower arc surface 10. This structural design, in conjunction with the spring 13, allows the temples to swing upwards, that is, to open outwards, and then quickly return to their original position. At the same time, it allows the temples to swing downwards, that is, to fold inwards, and then stably remain in the folded state.
