Description

Technical Field

[0001] This utility model relates to the field of eyeglass frame technology, specifically to an adjustable eyeglass frame. Background Technology

[0002] Eyeglass frames are the core support structure of eyeglasses, typically made of metal, plastic, or composite materials. Their primary function is to secure the lenses and maintain a stable fit on the face. They consist of several key components: the lens rims for holding the lenses; the bridge connecting the two rims to maintain lens spacing; the nose pads supporting the nose and distributing pressure; and the temples extending behind the ears to fix the glasses in position. Eyeglass frames not only affect wearing comfort (through adjustments to the nose pad angle and temple curvature) but also determine the aesthetic style of the glasses (such as shape, color, and material design), serving as the fundamental carrier of both functionality and aesthetics.

[0003] However, existing eyeglass frames are not easily adjustable in length, which can lead to discomfort such as pinching the head or causing pain behind the ears due to excessively short temples, while also preventing the glasses from slipping and wobbling due to excessive looseness. Therefore, those skilled in the art have provided an adjustable eyeglass frame to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable eyeglass frame to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adjustable eyeglass frame includes an eyeglass frame body, with connecting hinges on both sides of the eyeglass frame body. The eyeglass frame body is rotatably connected to a temple body via the connecting hinges. A length adjustment mechanism is fixed on one side of the temple body. A connecting temple is connected to the outside of the length adjustment mechanism. A connecting mechanism is provided on the outside of the length adjustment mechanism.

[0007] The length adjustment mechanism includes a fixed sleeve, a length adjustment bracket extending into the fixed sleeve is movably inserted into one side of the fixed sleeve, a handle pad is fixed to the outside of the length adjustment bracket, a limit threaded rod is installed on the outside of the length adjustment bracket, a limit plate is fixed to one end of the limit threaded rod, an anti-slip pad is movably sleeved on the outside of the limit threaded rod, and a positioning threaded sleeve is threadedly connected to the outside of the limit threaded rod.

[0008] As a further embodiment of this utility model: the connecting mechanism includes a first mounting block, a long semi-threaded rod fixed to the outer side of the first mounting block, a limit block fixed to one end of the long semi-threaded rod, a second mounting block installed on the outer side of the fixing sleeve, a short semi-threaded rod fixed to the outer side of the second mounting block, and a metal nut threadedly connected to the outer sides of the short semi-threaded rod and the long semi-threaded rod.

[0009] As a further improvement of this utility model: the first mounting block and the main body of the temple are fixedly connected, and the outer side of the metal nut is knurled.

[0010] As a further improvement of this utility model: the corresponding surfaces of the first mounting block and the second mounting block are fitted together, and the radius of the long semi-threaded rod and the radius of the short semi-threaded rod are equal.

[0011] As a further embodiment of this utility model: the fixing sleeve and the temple body are fixedly connected, and the length adjustment bracket and the connecting temple are fixedly connected.

[0012] As a further improvement of this utility model, a limiting groove is provided inside the fixed sleeve, and the size of the limiting groove is adapted to the size of the length adjustment bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This device is equipped with a length adjustment mechanism, which facilitates the fixing of the fixing sleeve and the length adjustment frame, so as to make the temple length easy to adjust and lock. This avoids the pain of pinching the head or behind the ears caused by the temples being too short, and also avoids the problem of the glasses slipping and shaking due to being too loose. In addition, some people's head or ear positions may be slightly asymmetrical. The ability to independently adjust the length of the temples on both sides helps to keep the glasses horizontal and balanced, improving the fit, comfort and stability of the glasses, and meeting the needs of different users.

[0015] 2.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 In this embodiment of the utility model, an adjustable eyeglass frame includes an eyeglass frame body 1. The eyeglass frame body 1 is characterized in that connecting hinges 2 are provided on both sides of the eyeglass frame body 1. The eyeglass frame body 1 is rotatably connected to a temple body 3 through the connecting hinges 2. A length adjustment mechanism 4 is fixed on one side of the temple body 3. A connecting temple 5 is connected to the outside of the length adjustment mechanism 4. A connecting mechanism 6 is provided on the outside of the length adjustment mechanism 4.

[0023] The length adjustment mechanism 4 includes a fixed sleeve 41. A length adjustment bracket 42 extending into the fixed sleeve 41 is movably inserted into one side of the fixed sleeve 41. A handle pad 43 is fixed to the outside of the length adjustment bracket 42. A limiting threaded rod 44 is installed on the outside of the length adjustment bracket 42. A limiting plate 45 is fixed to one end of the limiting threaded rod 44. An anti-slip pad 46 is movably sleeved on the outside of the limiting threaded rod 44. A positioning threaded sleeve 47 is threadedly connected to the outside of the limiting threaded rod 44. The fixed sleeve 41 is fixedly connected to the temple body 3, and the length adjustment bracket 42 is fixedly connected to the connecting temple 5. A limiting through groove is opened inside the fixed sleeve 41. The size of the limiting through groove is adapted to the size of the length adjustment bracket 42. When adjusting the wearing length of the connecting temple 5, the anti-slip pad 46 can be rotated to move the corresponding surface of the anti-slip pad 46 away from the positioning thread. The sleeve 47 can release the pressure of the anti-slip pad 46 on the positioning threaded sleeve 47, and at the same time release the lock between the fixing sleeve 41 and the length adjustment bracket 42. The user pulls the handle pad 43 to make one end of the length adjustment bracket 42 slide inside the fixing sleeve 41. At this time, the length adjustment bracket 42 moves the connecting temple 5 at the same time, which can adjust the length of the length adjustment bracket 42 extending out of the fixing sleeve 41 and adjust the position of the connecting temple 5, thus achieving the purpose of adjustable temple length. After the length adjustment bracket 42 is adjusted to the appropriate position, the anti-slip pad 46 is rotated clockwise again to make the corresponding surface of the anti-slip pad 46 tightly adhere to the positioning threaded sleeve 47, which conveniently completes the fixation between the fixing sleeve 41 and the length adjustment bracket 42, achieving the purpose of easy adjustment and locking of temple length, and avoiding head clamping or ear pain caused by temples that are too short.

[0024] In one embodiment of this utility model, the connecting mechanism 6 includes a first mounting block 61, a long semi-threaded rod 62 fixed to the outside of the first mounting block 61, a limit block 63 fixed to one end of the long semi-threaded rod 62, a second mounting block 64 mounted on the outside of the fixing sleeve 41, a short semi-threaded rod 65 fixed to the outside of the second mounting block 64, and a metal nut 66 threadedly connected to the outside of the short semi-threaded rod 65 and the long semi-threaded rod 62. The first mounting block 61 and the temple body 3 are fixedly connected. The outside of the metal nut 66 is knurled. The corresponding surfaces of the first mounting block 61 and the second mounting block 64 are in contact. The radius of the long semi-threaded rod 62 and the radius of the short semi-threaded rod 65 are equal.

[0025] The working principle of this utility model is as follows: This device is equipped with a length adjustment mechanism 4. When adjusting the wearing length of the connecting temple 5, the anti-slip pad 46 can be rotated to move the corresponding surface of the anti-slip pad 46 away from the positioning threaded sleeve 47, thereby releasing the pressure of the anti-slip pad 46 on the positioning threaded sleeve 47 and simultaneously releasing the lock between the fixing sleeve 41 and the length adjustment bracket 42. The user pulls the handle pad 43 to move one end of the length adjustment bracket 42 within the fixing sleeve 41. At this time, the length adjustment bracket 42 moves the connecting temple 5 simultaneously, allowing adjustment of the length of the length adjustment bracket 42 extending out of the fixing sleeve 41 and adjusting the position of the connecting temple 5, thus achieving the purpose of adjustable temple length. After the length adjustment bracket 42 is adjusted to the appropriate position, the anti-slip pad 46 is rotated clockwise again to make the corresponding surface of the anti-slip pad 46 tightly adhere to the positioning threaded sleeve 47, conveniently completing the fixation between the fixing sleeve 41 and the length adjustment bracket 42. This achieves the purpose of easy adjustment and locking of temple length, avoiding the problem of temples being too short. This design avoids head pinching or ear pain, and prevents glasses from slipping and wobbling due to excessive looseness. It also addresses the issue of slightly asymmetrical head or ear positions in some individuals, allowing for independent adjustment of the temple lengths to maintain horizontal balance. This enhances the fit, comfort, and stability of the glasses, meeting the needs of different users. The connecting mechanism 6, when the temple body 3 and the fixing sleeve 41 are fixedly connected, aligns the corresponding surfaces of the first mounting block 61 on the outer side of the temple body 3 with the second mounting block 64. At this time, the corresponding surfaces of the long semi-threaded rod 62 on the outer side of the first mounting block 61 and the short semi-threaded rod 65 on the outer side of the second mounting block 64 are aligned. A metal nut 66 is then used to thread the short semi-threaded rod 65 and the long semi-threaded rod 62, easily securing the long semi-threaded rod 62 and the short semi-threaded rod 65. This ensures a stable connection between the first mounting block 61 and the second mounting block 64, reinforcing the connection between the temple body 3 and the fixing sleeve 41 and improving the stability of the device.

[0026] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
