Description

Technical Field

[0001] This utility model relates to the field of eyeglass accessories technology, specifically to an adjustable ear hook anti-slip temple. Background Technology

[0002] In daily life, the anti-slip design of glasses is crucial, especially for outdoor enthusiasts. Choosing suitable anti-slip glasses accessories, such as non-slip straps and silicone ear hooks, can effectively prevent glasses from slipping off.

[0003] When in use, the anti-slip straps, due to their own elasticity, pull the nose pads tightly against the bridge of the nose, causing discomfort. Additionally, the way they wrap around the back of the head is not aesthetically pleasing. The silicone ear hooks, fitted at the end of the temples, can shift and move depending on the temple's thickness. During exercise, oily sweat secreted from the bridge of the nose can cause the nose pads to slip off, resulting in the silicone ear hooks failing to hold the lenses properly, affecting lens focusing. Furthermore, neither of these methods allows for adaptive adjustment of the temple length, leading to pillow compression of the longer temple ends when lying flat or on one's side, hindering normal daily use of the glasses and making them impractical. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable ear hook anti-slip temple for glasses in order to solve the above problems, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This utility model provides an adjustable ear hook anti-slip temple, including a temple, an ear hook connecting part, and an ear hook. The ear hook connecting part is integrally formed at the tail end of the temple. A groove is formed on the bottom surface of the ear hook connecting part. A connecting plate that matches the groove is fixedly connected to the front end of the ear hook. A bolt connecting part is provided on the side wall of the ear hook connecting part for connecting the ear hook and allowing it to rotate in the groove.

[0010] Preferably, both the movable groove and the locking block are square in design and fit with a clearance. A herringbone-shaped protrusion is fixedly connected to the end face of the locking block, and the herringbone-shaped protrusion engages with the gap between several protruding teeth.

[0011] Preferably, the elastic structure includes a sliding hole formed in the bottom of the movable groove, and a sliding rod that slides into the sliding hole is fixedly connected to the end face of the locking block. A spring is connected between the end of the sliding rod and the bottom of the sliding hole.

[0012] Preferably, both the slide rod and the slide hole are hexagonal in design, and a connecting rope is connected between the inner bottom of the slide rod and the slide hole.

[0013] Preferably, the plug-in assembly includes a plug hole on the upper surface of the ear hook connection portion, a movable plug plate is inserted into the plug hole, the lower end of the plug hole is integrally formed with a storage groove, and the lower end of the storage groove is connected to the movable groove.

[0015] Preferably, both the ear hook connector and the bottom side of the ear hook are made of non-slip silicone material.

[0016] The beneficial effects are:

[0017] By pressing down the ear hook, during rotation, the protruding teeth at the end of the connecting plate squeeze the herringbone-shaped protrusion and the locking block, causing them to elastically retract into the movable groove. According to the elasticity of the spring, the herringbone-shaped protrusion is locked into the next position of the protruding teeth. Then, pressing down the movable insert plate causes the n-shaped block to lock into the movable groove, locking the ear hook so that it cannot rotate. The bendable and adjustable ear hook achieves the effect of fixing the glasses to the ears during exercise. At the same time, the downward bending angle of the ear hook can be adjusted according to different ear-eye distances to improve the fit. The adjustment of the ear hook also avoids the situation of the temples behind the ears protruding too much when lying down or leaning, which would cause the glasses to top or press against the glasses, thus improving wearing comfort and practicality.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] See Figures 1-4 As shown, this utility model provides an adjustable ear hook anti-slip temple, including a temple 1, an ear hook connecting part 2, and an ear hook 3. The ear hook connecting part 2 is integrally formed on the tail end of the temple 1. A groove 7 is provided on the bottom surface of the ear hook connecting part 2. A connecting plate 8 that is adapted to the groove 7 is fixedly connected to the front end of the ear hook 3. A bolt connecting part 4 is provided on the side wall of the ear hook connecting part 2 for connecting the ear hook 3 and making it rotate in the groove 7. An elastic snap-fit ​​part 5 is provided at the inner bottom of the groove 7 for fixing the rotation angle of the connecting plate 8.

[0027] Reference Figure 2 As shown, the bolt connector 4 includes bolt holes 401 that pass through both sides of the groove 7. Bolts 402 are threaded into the bolt holes 401. The front end of the connecting plate 8 has a through hole 403 that fits with the bolt 402. By placing the connecting plate 8 inside the groove 7 and then inserting the bolt 402 into both the through hole 403 and the bolt hole 401 and rotating it, the connection between the connecting plate 8 and the ear hook 3 can be completed, allowing the ear hook 3 to rotate around the bolt 402 as an axis.

[0028] Specifically, the bolt 402 has a smooth shaft section in the middle, and the smooth shaft section is sleeved in the through hole 403. By designing the smooth shaft section, the connecting plate 8 can avoid wear with the thread when it rotates.

[0029] Reference Figure 4 As shown, the elastic snap-fit ​​component 5 includes a movable groove 501 formed in the bottom of the groove 7. A snap-fit ​​block 502 is slidably connected in the movable groove 501. Several protrusions 504 that engage with the snap-fit ​​block 502 are fixedly connected to the end of the connecting plate 8. A spring structure is provided at the bottom of the movable groove 501 to drive the snap-fit ​​block 502 to move towards the protrusions 504. A plug-in component 6 is provided above the movable groove 501 to restrict the snap-fit ​​block 502 from moving into the movable groove 501. Both the movable groove 501 and the snap-fit ​​block 502 are square and have a clearance fit. A herringbone-shaped protrusion 503 is fixedly connected to the end face of the snap-fit ​​block 502. The herringbone-shaped protrusion 503 engages with the gap between the protrusions 504 and the spring structure includes a sliding hole 505 formed in the bottom of the movable groove 501. A slide rod 506 is fixedly connected to the end face of 502 and slidably inserted into the slide hole 505. A spring 507 is connected between the end of the slide rod 506 and the inner bottom of the slide hole 505. When the ear hook 3 is pressed down, during the rotation, the protruding teeth 504 at the end of the connecting plate 8 press the herringbone protrusion 503 and the locking block 502 back into the movable groove 501, and at the same time push the spring 507 to elastically contract. When it rotates to the gap between the two protruding teeth 504, the herringbone protrusion 503 is locked into the next position according to the elastic bending of the spring 507, so as to realize the adjustment of the pressing angle of the ear hook 3 and achieve a good anti-dropping effect. The design of the herringbone protrusion 503 allows the protruding teeth 504 to contact the slope of the herringbone protrusion 503 when rotating with the connecting plate 8, so as to avoid jamming.

[0030] Specifically, both the slide rod 506 and the sliding hole 505 are hexagonal in design. A connecting rope 508 connects the inner bottom of the slide rod 506 and the sliding hole 505. The hexagonal design makes the locking block 502 more stable when it moves back and forth in elastic engagement, while preventing the herringbone protrusion 503 from deflecting or wobbling. This ensures that the herringbone protrusion 503 and several protruding teeth 504 are stably engaged. The connecting rope 508 can prevent the slide rod 506 and the locking block 502 from slipping out, thus ensuring the integrity and stability of the structure.

[0031] As an optional implementation, the plug-in assembly 6 includes a plug hole 601 formed on the upper surface of the ear hook connecting part 2. A movable plug plate 602 is inserted into the plug hole 601. The lower end of the plug hole 601 is integrally formed with a storage groove 603, and the lower end of the storage groove 603 communicates with the movable groove 501. The lower end of the movable plug plate 602 is fixedly connected to an n-shaped block 604 for reciprocating movement in the storage groove 603 and the movable groove 501. The upper end of the movable plug plate 602 is fixedly connected to a push-pull auxiliary plate 605. The width of the central recess of the n-shaped block 604 is greater than the diameter of the slide rod 506, and the thickness of the n-shaped block 604 is adapted to the retraction displacement distance of the locking block 502. A connecting plate is fixedly connected to the upper side wall of the movable plug plate 602. The rubber pad on the inner wall of the socket 601 abuts against the friction. By pressing down the movable insert plate 602, it slides in the socket 601 until the n-shaped block 604 is inserted into the movable slot 501. At this time, the n-shaped block 604 abuts against the retractable space of the locking block 502, realizing the locking effect of the locking block 502, thereby locking the ear hook 3 so that it cannot rotate. At the same time, the movable insert plate 602 can be lifted by pushing and pulling the auxiliary plate 605, which drives the n-shaped block 604 to move up into the storage slot 603. At this time, the movement of the locking block 502 will be unrestricted, and the ear hook 3 can rotate freely. The rubber pad at the upper end of the movable insert plate 602 can rub against its inner wall after it is fully inserted into the socket 601, providing a locking effect based on friction for the insertion of the movable insert plate 602.

[0032] Specifically, the bottom sides of the ear hook connection part 2 and the ear hook 3 are made of anti-slip silicone material, which makes the temple 1 more slip-resistant and comfortable to wear.

[0033] The working principle of this utility model:

[0034] In use, the ear hook 3 is pressed down, causing it to rotate downwards on the bolt 402 through the through hole 403. During the rotation, the protrusions 504 at the end of the connecting plate 8 press the herringbone protrusion 503 and the locking block 502 back into the movable groove 501, while simultaneously pushing the spring 507 to elastically contract. When it rotates to the gap between the two protrusions 504, the herringbone protrusion 503 is locked into the next position according to the elasticity of the spring 507, thereby adjusting the downward pressing angle of the ear hook 3. Then, the movable insert plate 602 is pressed down to slide in the insert hole 601 until the n-shaped block 604 is locked into the movable groove 501. At this time, the n-shaped block 604 abuts against the contraction and movement space of the locking block 502, thereby achieving the locking effect of the locking block 502 and locking the ear hook 3 so that it cannot rotate.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
