Description

Technical Field

[0001] This application relates to the technical field of medical devices, and particularly to an anti-shake composite multi-purpose glasses fixing clip. Background Art

[0002] Glasses, as a common vision correction tool, are widely used in clinical practice. For patients with refractive errors such as myopia, hyperopia, and astigmatism, wearing glasses with appropriate degrees can significantly improve vision and enhance the quality of life.

[0003] In the medical field, especially during delicate operations such as ophthalmic examinations or cardiac surgeries, medical staff usually need to wear glasses to obtain a clear field of vision. At the same time, in order to provide sufficient illumination, they also need to wear a medical headlamp. However, there is a problem of inconsistent illumination and vision between the existing head-mounted headlamps and glasses during surgeries. This inconsistency will increase the difficulty of surgical operations and may even affect the accuracy of surgeries and the safety of patients. Utility Model Content

[0004] In order to improve the consistency between the illumination direction of the headlamp and vision, this application provides an anti-shake composite multi-purpose glasses fixing clip.

[0005] This application provides an anti-shake composite multi-purpose glasses fixing clip, adopting the following technical solutions:

[0006] An anti-shake composite multi-purpose glasses fixing clip includes a fixing clip body. The fixing clip body has a glasses clamping part and a headlamp connecting part. The glasses clamping part includes a positioning rod and a movable rod. The positioning rod and the movable rod are respectively arranged on both sides of the fixing clip body. The positioning rod and the movable rod extend downward, and a clamping space for clamping glasses is formed between the positioning rod and the movable rod.

[0007] By adopting the above technical solutions, the glasses clamping part realizes the clamping of the fixing clip and the glasses; the headlamp connecting part realizes the convenient connection of the headlamp or other auxiliary devices, so that the headlamp can be fixed on the glasses, avoiding the problem of inconsistent illumination area and visual area when wearing the headlamp alone; the glasses clamping part is composed of a positioning rod and a movable rod, and the two cooperate to form a clamping space, ensuring the stability of the glasses during wearing, reducing visual blurring caused by shaking or vibration, and enhancing the user experience.

[0008] Optionally, the movable rod is rotatably arranged on both sides of the fixing clip body. The glasses clamping part further includes an elastic member for driving the movable rod to always rotate towards the direction close to the positioning rod, and a driving member for driving the movable rod to rotate away from the positioning rod.

[0009] By adopting the above technical solution, the elastic member ensures that the movable rod always rotates towards the positioning rod direction without external force, maintaining the clamping force; while the driving member facilitates the rotation of the movable rod to remove or clamp the fixing clip.

[0010] Optionally, the movable rod includes a first rod arranged along the horizontal direction, a third rod arranged along the vertical direction, and a second rod connected between the first rod and the third rod. The first rod is rotatably arranged on the fixing clip body. The second rod is inclined, and a clamping portion for clamping the upper edge of the spectacle frame is formed at the connection between the second rod and the third rod.

[0011] By adopting the above technical solution, the clamping portion formed at the connection between the first rod and the second rod effectively fixes the upper edge of the spectacle frame, preventing the glasses from slipping during wearing.

[0012] Optionally, the third rod has an arc-shaped abutting surface protruding towards the spectacle lens direction.

[0013] By adopting the above technical solution, the design of the arc-shaped abutting surface on the third rod not only avoids damage or deformation of the lens caused by single-point contact, but also the protruding arc surface design can facilitate the third rod to abut tightly against the lens, ensuring the clamping effect.

[0014] Optionally, the driving member is a holding piece. Two connecting grooves are formed by the lower end of the holding piece extending downward. The two first rods respectively pass through the two connecting grooves and are fixedly connected to the holding piece.

[0015] By adopting the above technical solution, the user can drive the movable rod to rotate by driving the holding piece to rotate, making the use of the fixing clip more convenient.

[0016] Optionally, the elastic member is a torsion spring sleeved on the side wall of the first rod. The fixed end of the torsion spring abuts against the fixing clip body, and the movable end of the torsion spring abuts against the side wall of the holding piece. When the holding piece rotates towards the direction of the movable end of the torsion spring, the third rod moves away from the spectacle lens direction. When the third rod abuts against the spectacle lens, the movable end of the torsion spring has an elastic force to drive the holding piece to rotate in the direction away from the movable end.

[0017] By adopting the above technical solution, the application of the torsion spring as an elastic member provides a stable source of clamping force for the fixing clip. When the holding piece is operated, the elastic force of the torsion spring will automatically adjust according to the rotation direction of the holding piece, ensuring that the movable rod can quickly respond and reach the required clamping state. This automatic adjustment mechanism improves the intelligent level of the fixing clip.

[0018] Optionally, connecting rods are respectively provided on two sides of the two positioning rods facing away from each other, and a clamping column is provided on the end of the connecting rod facing the side of the clamping space, and when the glasses are clamped in the clamping space, the clamping column abuts against the glasses lens.

[0019] By adopting the above technical solution, a connecting rod and a clamping column are arranged on the positioning rod, which further enhances the stability of the glasses clamping. The abutment between the clamping column and the glasses lens, and the clamping between the lens and the frame, effectively prevent the glasses from falling off under external factors such as intense exercise or strong wind, and improve the safety performance of the fixing clip.

[0020] Optionally, the positioning rod and the clamping column are made of polymer materials, and the holding piece and the movable rod are made of metal materials.

[0021] By adopting the above technical solution, the positioning rod and clamping column made of polymer material have good toughness and wear resistance, and can maintain a stable clamping effect for a long time; while the holding piece and movable rod made of metal material provide sufficient strength and hardness, ensuring the durability and reliability of the fixing clamp.

[0022] Optionally, the headlamp connection portion includes a connection block, the connection block is located on a side of the fixing clamp body away from the movable rod, and the connection block is provided with a threaded hole for connecting the headlamp.

[0023] By adopting the above technical solution, the threaded holes on the connecting block provide a reliable interface for the connection of the headlight, so that the user can install different types of headlights on the fixing clamp as needed to meet different usage scenarios and needs, and it can also facilitate the connection of other auxiliary equipment.

[0024] In summary, the present application includes at least one of the following beneficial effects:

[0025] 1. The glasses are clamped by the positioning rod and the movable rod, and the headlamp is firmly connected through the headlamp connection part to ensure the consistency of lighting and vision, thereby improving the accuracy and efficiency of surgical operations;

[0026] 2. Through the structural design of positioning rods, movable rods and clamping columns, the glasses are firmly clamped, which effectively prevents the glasses from shaking and falling off during wearing and improves the wearing stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following further describes the present application in conjunction with the attached Figures 1-3 drawings for a more detailed explanation.

[0032] An embodiment of the present application discloses an anti-shake composite multi-purpose glasses fixing clip. Referring to Figure 1 and Figure 2 , the glasses fixing clip includes a fixed clip body 1. Among them, the fixed clip body 1 mainly consists of two parts: a glasses clamping part and a headlamp connecting part; among them, the fixed clip body 1 is mainly in a rectangular block structure. The glasses clamping part mainly includes a positioning rod 2 and a movable rod 3. The positioning rod 2 and the movable rod 3 are respectively arranged on both sides of the fixed clip body 1 and extend downward to form a clamping space 4 for clamping the glasses. When in use, the fixed clip body 1 is clamped between the glasses through the positioning rod 2 and the movable rod 3, and the two positioning rods 2 and the two movable rods 3 are respectively located on both sides of the two lenses, so as to position the fixed clip. Then, the headlamp is fixed on the fixed clip body 1 through the headlamp connecting part; it is convenient to fix the headlamp, avoiding the trouble of wearing an additional headlamp. At the same time, the headlamp is directly fixed on the fixed clip body 1, making the illumination position of the headlamp consistent with the vision and improving the vision clarity of the wearer.

[0033] Referring to Figure 1 and Figure 2 , in this embodiment, further, in order to increase the fixing effect between the glasses clamping part and the glasses, the movable rod 3 is rotatably arranged on the fixed clip body 1. At the same time, the glasses clamping part also includes an elastic member 5 and a driving member 6. The function of the elastic member 5 is to always drive the movable rod 3 to rotate towards the direction close to the positioning rod 2, so as to ensure that the glasses are firmly clamped in the clamping space 4; and the driving member 6 is used to drive the movable rod 3 to rotate away from the positioning rod 2 when needed, so as to easily remove the fixed clip or clamp the fixed clip on the glasses.

[0034] Referring to Figure 2 and Figure 3In this embodiment, the movable rod 3 includes a first rod 31 arranged in the horizontal direction, a third rod 33 arranged in the vertical direction, and a second rod 32 connecting the first rod 31 and the third rod 33. The first rod 31 is a cylindrical straight rod. A support is provided on the upper surface of the fixing clamp body 1 protruding upward. The first rod 31 passes through the support along the length direction of the fixing clamp body 1 and is rotatably connected with the support. At the same time, the two first rods 31 can be connected to each other. The second rod 32 is arranged at an angle, and a bent clamping portion is formed at the connection with the third rod 33. When the fixing clamp is fixed on the glasses, it can clamp the upper edge of the glasses frame, further enhancing the stability of the clamping. Further optionally, the middle part of the third rod 33 body is bent toward the direction of the glasses lens to form an arc end, so as to have an arc-shaped abutting surface protruding toward the direction of the glasses lens. This abutting surface can make the third rod 33 press against the glasses lens, thereby ensuring the stability of the clamping and preventing the headlight set on the fixing clamp from shaking during use.

[0035] Reference Figure 2 and Figure 3 In this embodiment, the driving member 6 is configured as a gripping piece 61, and the elastic member 5 is configured as a torsion spring 51; specifically, the torsion spring 51 is sleeved on the first rod 31, the fixed end of the torsion spring 51 abuts or is fixed on the fixing clamp body 1, and the movable end abuts on the side wall of the gripping piece 61, which is used to provide elastic force for the gripping piece 61; the lower end of the gripping piece 61 extends downward and winds to form two connecting grooves, the first rod 31 passes through the two connecting grooves, and the side walls of the connecting grooves and the side walls of the first rod 31 abut against each other, so that the first rod 31 is fixedly connected to the gripping piece 61, so that when the gripping piece 61 rotates, the two first rods 31 can be driven to rotate simultaneously; the movable end of the torsion spring 51 abuts against one end of the gripping piece 61 close to the positioning rod 2. In order to facilitate the application of force to the gripping piece 61, the upper end of the gripping piece 61 is preferably bent toward the movable end of the torsion spring 51 to form a force application surface that is convenient for applying force downward.

[0036] When the holding piece 61 is driven to rotate toward the positioning rod 2, that is, toward the side where the movable end of the torsion spring 51 is located, the transmission of the connecting block 8 and the first rod 31 can drive the third rod 33 on the movable rod 3 to move in the direction away from the lens, thereby increasing the distance between the positioning rod 2 and the movable rod 3, which is convenient for fixing or removing the fixing clamp; when the holding piece 61 is released, under the elastic force of the torsion spring 51, the movable rod 3 can be driven to rotate in the opposite direction, that is, the third rod 33 is rotated in the direction close to the lens of the glasses and pressed against the side wall of the lens, so that the fixing clamp can be fixed on the glasses, and at this time, the movable end of the torsion spring 51 still has the elastic force to drive the holding piece 61 to rotate in the direction away from the movable end, that is, it can continuously provide the elastic force of the third rod 33 to press against the side wall of the lens, thereby ensuring that the glasses are firmly clamped in the clamping space 4, further preventing the headlamp set on the fixing clamp from shaking during use.

[0037] ReferenceFigure 1 and Figure 2 The two positioning rods 2 extend in front of the two lenses of the glasses respectively, and the two positioning rods 2 and the two movable rods 3 are arranged opposite to each other in the front and back directions, and can cooperate with the movable rods 3 to clamp on the two lenses respectively to ensure the fixing effect. In an optional embodiment, in order to further increase the stability, arc-shaped connecting rods 7 are respectively fixed on the two sides of the two positioning rods 2 facing away from each other. The connecting rods 7 are preferably integrally formed with the positioning rods 2. A clamping column 71 is fixed at the end of the connecting rod 7. The clamping column 71 is located on the side of the positioning rod 2 facing the clamping space 4, and the end face of the clamping column 71 is preferably rounded to avoid scratching the glasses by the clamping column 71. When the fixing clip is fixed on the glasses, the clamping column 71 is located at the lens position, so that through the cooperation between the clamping column 71 and the spectacle frame, the upward movement of the clamping column 71 relative to the spectacle frame can be restricted, and the stability of the fixing clip fixed on the glasses is increased.

[0038] In this embodiment, the positioning rods 2, the connecting rods 7 and the clamping columns 71 are preferably made of a lightweight and elastic polymer material. This material can not only effectively reduce the weight of the whole fixing clip, but also generate a certain deformation when subjected to external force, so as to better adapt to and protect the glasses; while the movable rods 3 and the holding pieces 61 are made of metal materials to provide sufficient strength and wear resistance to ensure the long-term use stability of the fixing clip.

[0039] Referring to Figure 1 and Figure 2 In this embodiment, the headlamp connecting portion includes a connecting block 8. The connecting block 8 is located on the side of the fixing clip body 1 away from the movable rod 3, and preferably, the connecting block 8 can be integrally formed with the fixing clip body 1; a threaded hole 81 for connecting the headlamp is opened on the side of the connecting block 8 away from the movable rod 3. The threaded hole 81 is preferably opened at the center position of the connecting block 8. When the fixing clip is clamped on the glasses, the fixing clip body 1 is preferably located at the center position of the glasses, so that the headlamp can be connected to the center position of the fixing clip, and the irradiation range of the headlamp can have better consistency with the vision. In other embodiments, the threaded hole 81 can also be used to cooperate with the installation of other auxiliary devices.

[0040] The implementation principle of a kind of anti-shake composite multi-purpose glasses fixing clip according to the embodiment of the present application is as follows: during use, first fix the headlamp on the connecting block 8 by means of threaded connection; then press the holding piece 61 to drive the movable rod 3 to rotate in a direction away from the positioning rod 2, and then clamp the glasses in the clamping space 4, and release the holding piece 61. The movable rod 3 rotates under the action of the torsion spring 51 to clamp the glasses; thus, the headlamp can be fixed on the glasses through the fixing clip.

[0041] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
