Description

Technical Field

[0001] This utility model belongs to the field of eyeglasses technology, specifically relating to a light refraction structure for movable eyeglasses. Background Technology

[0002] In today's society, the division of labor is becoming increasingly specialized, and many jobs require operators to maintain a specific posture for a long time. Among them, working with one's head down for long periods of time is extremely common in many professions, with dentists being a typical example. During dental treatment, dentists need to focus on the fine structures and lesions inside the patient's mouth for a long time. Whether it is performing a dental examination, filling a cavity, or performing complex root canal treatment or orthodontic procedures, dentists need to keep their heads down and their eyes fixed on the inside of the patient's mouth. This working posture causes the dentist's cervical spine to be in an excessively forward-flexed state for a long time.

[0003] However, when dentists work with their heads down for extended periods, the physiological curvature of the cervical spine changes. The original forward curve gradually straightens or even reverses, significantly increasing the pressure on the intervertebral discs. Over time, this can easily lead to disc degeneration and herniation, compressing surrounding nerves and blood vessels, thus causing cervical spondylosis. In addition to cervical spine problems, prolonged work with the head down also puts a great burden on the shoulders. In this posture, the shoulder muscles need to continuously contract to maintain the position of the head and the balance of the body. The trapezius, levator scapulae, and other muscles in the shoulder are in a state of tension for a long time without sufficient rest and relaxation. Over time, this leads to muscle fatigue and spasms, which in turn cause shoulder strain. Shoulder strain can cause shoulder pain and limited mobility, seriously affecting the dentist's work efficiency and quality of life. Utility Model Content

[0004] The purpose of this invention is to provide a movable eyeglass light refraction structure to solve the problems of cervical spondylosis and shoulder strain caused by prolonged head-down work.

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

[0006] A movable eyeglass light refraction structure, comprising:

[0007] A frame, wherein a lens is disposed inside the frame, and temples are hinged to both sides of the frame;

[0008] A refractive structure is provided on one side of the mirror frame. The refractive structure includes a prism movably mounted on one side of the mirror frame for refracting light. A telescopic rod is movably mounted on one side of the mirror frame. The telescopic rod has internal damping. One end of the telescopic rod is connected to the prism. A gear is mounted on the outside of the telescopic rod. A rack is movably mounted on one side of the gear and meshes with the gear.

[0009] Preferably, a telescopic rod is movably installed on the side of the mirror frame near the prism, a support plate is fixedly installed on the top of the prism, and the end of the telescopic rod away from the mirror frame is fixedly connected to the support plate.

[0010] Preferably, a gear is fixedly installed on the outside of the telescopic rod near the side of the mirror frame, a rotating shaft is movably installed on the side of the mirror frame near the gear, a rack is fixedly installed on the outside of the rotating shaft, and the rack meshes with the gear.

[0011] Preferably, two inclined plates are fixedly installed on the side of the frame near the rack, the two inclined plates are symmetrically arranged on both sides of the rack, and each of the two inclined plates is connected to the rack by a spring.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) This utility model adds a refractive structure to ordinary glasses, so that the operator can work without looking down. This fundamentally changes the traditional way of working with the head down. For dentists and other people who work with their heads down for a long time, this means that their cervical spine and shoulders no longer bear long-term pressure and burden. The cervical spine can maintain its normal physiological curvature, reducing the risk of cervical disc degeneration and herniation, thus effectively preventing the occurrence of cervical spondylosis. At the same time, the shoulder muscles are also fully relaxed and rested, avoiding muscle fatigue and spasm, and reducing the incidence of shoulder strain.

[0014] (2) This utility model can quickly switch between working and non-working states, which greatly improves the flexibility of use. When working, the operator only needs to flip the prism downward to obtain the lower field of vision and focus on the work. When it is necessary to pick up items, communicate with patients, or perform other non-working operations, the operator only needs to flip the prism upward, and the prism will not block the ordinary lens. The operator can restore normal vision without being disturbed. This quick switching function allows the operator to adjust the state of the glasses at any time according to different work scenarios and needs, which improves work efficiency and convenience.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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] Example 1:

[0023] Please see Figure 1 - Figure 5 As shown, a movable eyeglass light refraction structure includes:

[0024] The frame 1 has a lens 11 inside and temples 12 are hinged to both sides of the frame 1.

[0025] A refractive structure 2 is disposed on one side of the mirror frame 1. The refractive structure 2 includes a prism 21 movably mounted on one side of the mirror frame 1. The prism 21 is used to refract light. A telescopic rod 22 is movably mounted on one side of the mirror frame 1. The telescopic rod 22 is equipped with damping. One end of the telescopic rod 22 is connected to the prism 21. A gear 24 is mounted on the outside of the telescopic rod 22. A rack 26 is movably mounted on one side of the gear 24. The rack 26 meshes with the gear 24.

[0026] Specifically, a telescopic rod 22 is movably installed on the side of the frame 1 near the prism 21. A support plate 23 is fixedly installed on the top of the prism 21. The end of the telescopic rod 22 away from the frame 1 is fixedly connected to the support plate 23. A gear 24 is fixedly installed on the outside of the telescopic rod 22 near the frame 1. A rotating shaft 25 is movably installed on the side of the frame 1 near the gear 24. A rack 26 is fixedly installed on the outside of the rotating shaft 25. The rack 26 meshes with the gear 24. Two inclined plates 27 are fixedly installed on the side of the frame 1 near the rack 26. The two inclined plates 27 are symmetrically arranged on both sides of the rack 26. A spring 28 connects both inclined plates 27 to the rack 26.

[0027] As shown above, the prism 21 is located on the outside of the frame 1. When light passes through the normal lens 11, it enters the prism 21 and is refracted by the prism 21, allowing the operator to see the field of view directly below. As a common optical element, the prism 21 has unique light refraction characteristics. A light-shielding cover (not shown in the figure) is provided above the prism 21 to prevent light from the top from affecting the refraction effect. The telescopic rod 22 can change the distance between the prism 21 and the lens 11 to achieve focusing, meeting the visual needs of different operators and different work scenarios. Because the telescopic rod 22 is movably connected, it can also rotate the prism 21 upwards, i.e., rotate along the axis of the telescopic rod 22. During operation, the prism 21 is set parallel to the lens 11, i.e., in a downward-flipped state. The telescopic rod 22 allows the operator to obtain a downward field of view. When it is necessary to retrieve items or communicate normally with the patient, the prism 21 can be flipped upward to prevent it from blocking the lens 11 and ensure normal vision. During the rotation of the telescopic rod 22, the gear 24 will rotate synchronously. The rotation of the gear 24 will push the rack 26 to swing to one side. After the rotation stops, the spring 28 will push the rack 26 back to its original position. The rack 26 will still be locked on one side of the gear 24. Due to the cooperation of the gear 24 and the rack 26, the telescopic rod 22 needs to be rotated with a little force from the fingers. At the same time, the rack 26 being locked on one side of the gear 24 also provides a limiting effect for the gear 24, so that the prism 21 can remain in a suspended state and prevent the prism 21 from flipping downward on its own, ensuring the stability and reliability of the prism 21 when switching between different states.

[0028] When using the device, first wear the frame 1 on your face normally. When the operator needs to work with their head down, first flip the prism 21 downwards until the prism 21 is parallel to the lens 11. At this time, light passes through the lens 11 and enters the interior of the prism 21. After being refracted by the prism 21, the operator can see the field of view directly below through the prism 21, thus working in a level gaze state. If it is necessary to adjust the clarity of the field of view, the prism 21 can be pushed to extend or retract the telescopic rod 22, changing the distance between the prism 21 and the lens 11 to achieve focusing. When the operator needs to pick up items or communicate normally with the patient, flip the prism 21 upwards so that the prism 21 is no longer blocking the lens 11, and the operator can restore normal vision, making it convenient to perform other operations.
