Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, specifically to an eyeglasses structure with adjustable temples. Background Technology

[0002] The existing eyeglasses have a fixed shape. Since the temples are molded in one piece, people tend to adapt to the shape of the temples rather than the temples adapting to the contours of the face. This is especially true when the temples are placed on the ears, which can cause ear discomfort with prolonged wear.

[0003] Specifically, this manifests in two ways: first, the length of the temples cannot be adjusted, making it unsuitable for the differences in the distance from the bridge of the nose to the ears; and second, the different curvatures of each person's ears.

[0004] Therefore, it is necessary to improve the structure of the temples so that they can be extended and retracted in the length direction and the angle of the ear loops can be adjusted. Utility Model Content

[0005] To address the shortcomings of the aforementioned technologies, this invention provides an adjustable temple eyeglass structure.

[0006] A further feature of this utility model: an adjustable temple eyeglass structure, including a frame, temples, a drive slider, a spring, and a limiting member. The temples are divided into a hinge section and an ear loop section. One end of the hinge section is connected to the frame hinge, and the other end has a sliding hole along the length direction. The sliding hole has a limiting groove along the radial direction. The drive slider is adapted to the contour of the sliding hole, and its outer peripheral surface has a limiting protrusion that is adapted to and engages with the limiting groove. The drive slider has a first threaded hole at its center.

[0007] The lug section includes a lug part and a slide rod part. The end of the slide rod part is provided with an external thread and is threadedly engaged with the first threaded hole. The limiting member is sleeved on the slide rod part and is detachably engaged with the sliding hole opening for axial fixation. The spring is sleeved on the slide rod part and compressed between the limiting member and the drive slider.

[0008] A further feature of this invention is that a recessed hole is coaxially provided at the opening of the sliding hole, the recessed hole has an internal thread, the limiting member has an external thread adapted to the recessed hole, and the center of the limiting member has a through hole with a diameter larger than that of the sliding rod and smaller than that of the spring.

[0009] A further feature of this invention is that a recessed hole is coaxially provided at the opening of the sliding hole, and the limiting member is a rubber part that engages with the recessed hole. The center of the limiting member has a through hole with a diameter larger than that of the sliding rod and smaller than that of the spring.

[0010] A further feature of this invention is that the driving slider is disc-shaped with a cross-shaped limiting protrusion on its outer circumference, and the cross-sectional shape and size of the sliding hole and the limiting groove are adapted to the cross-sectional shape and size of the driving slider.

[0011] A further feature of this invention is that the temple also includes a separate arc-shaped segment, which is hinged to the lug end.

[0012] A further feature of this invention is that the surface of the ear loop is covered with a silicone pad layer.

[0013] The beneficial effects of this utility model are as follows: First, when the user needs to adjust the length of the temples, there is no need to do so manually. When wearing the glasses, the ear loops move axially within the sliding holes via the sliding rod, automatically adapting to the user's facial contours. The axial movement of the sliding rod drives the drive slider to compress the spring. The spring's restoring force drives the ear loops to always move closer to the frame, thereby tightening the ear loops and maintaining optimal wearing comfort while preventing them from becoming too loose and falling off.

[0014] At the same time, the curved segments are hinged together, allowing them to bend and move along the ear contour to fit each person's ear contour.

[0015] II. The structural design of the drive slider, spring, limiting component, and slide rod facilitates assembly. The drive slider, spring, limiting component, and slide rod are connected sequentially. After insertion into the sliding hole, the limiting component closes the opening of the sliding hole to complete the assembly. This is simple and convenient, allowing users to easily replace the lug sections with different colors, patterns, curvatures, and lengths according to their needs. Attached Figure Description

[0021] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figure 1-3 As shown,

[0022] An adjustable temple 2 eyeglass structure includes a frame 1, temple 2, drive slider 3, spring 4, and limiting member 5. The temple 2 is divided into a hinge section 21 and an ear loop section 22. One end of the hinge section 21 is hinged to the frame 1, and the other end has a sliding hole 23 along the length direction. The sliding hole 23 has a limiting groove 24 along the radial direction. The drive slider 3 is adapted to the contour of the sliding hole 23, and its outer peripheral surface is provided with a limiting protrusion 31 that is adapted to and engages with the limiting groove 24. The center of the drive slider 3 is provided with a first threaded hole 32.

[0023] The lug section 22 includes a lug portion 221 and a slide rod portion 222. The end of the slide rod portion 222 is provided with an external thread 223 and is threadedly engaged with the first threaded hole 32. The limiting member 5 is sleeved on the slide rod portion 222 and is detachably engaged with the opening of the sliding hole 23 for axial fixation. The spring 4 is sleeved on the slide rod portion 222 and compressed between the limiting member 5 and the driving slider 3.

[0024] A recessed hole 25 is coaxially provided at the opening of the sliding hole 23. The recessed hole 25 is provided with an internal thread. The limiting member 5 is provided with an external thread that matches the recessed hole 25. The center of the limiting member 5 is provided with a through hole with a diameter larger than that of the sliding rod part 222 and smaller than that of the spring 4.

[0025] A recessed hole 25 is coaxially provided at the opening of the sliding hole 23. The limiting member 5 is a rubber part that engages with the recessed hole 25. The center of the limiting member 5 is provided with a through hole with a diameter larger than that of the sliding rod part 222 and smaller than that of the spring 4.

[0026] The drive slider 3 is disc-shaped, with a cross-shaped limiting protrusion 31 on its outer circumference. The cross-sectional shape and size of the sliding hole 23 and the limiting groove 24 are adapted to the cross-sectional shape and size of the drive slider 3.

[0027] The temple also includes a separate arc-shaped section 26, which is hinged to the ear loop end.

[0028] A further feature of this invention is that the surface of the ear loop 221 is covered with a silicone pad layer.

[0029] The beneficial effects of this utility model are as follows: First, when the user needs to adjust the length of the temple 2, there is no need to do so manually. When wearing the glasses, the ear loop 221 moves axially within the sliding hole 23 via the sliding rod 222, automatically adapting to the user's facial contour length. The axial movement of the sliding rod 222 drives the drive slider 3 to compress the spring 4. The force of the spring 4 restoring its deformation drives the ear loop 221 to always move towards the frame 1, thereby tightening the ear loop 221, maintaining optimal wearing comfort while preventing the ear loop 221 from becoming too loose and falling off.

[0030] Meanwhile, the curved segments 26 are hinged together, allowing them to bend and move along the ear contour to fit each person's ear contour.

[0031] II. The structural design of the drive slider 3, spring 4, limiting member 5, and slide rod 222 facilitates assembly. The drive slider 3, spring 4, limiting member 5, and slide rod 222 are connected sequentially. After inserting into the sliding hole 23, the limiting member 5 closes the opening of the sliding hole 23 to complete the assembly. This is simple and convenient, allowing users to easily replace the hanging ear section 22 with different colors, patterns, curvatures, and lengths according to their needs.
