Description

Technical Field

[0001] This application relates to the technical field of medical optical fibers, and in particular to medical optical fiber connectors. Background Technology

[0002] Optical fiber, short for optical waveguide fiber, is a type of fiber made of glass or plastic that serves as a means of light transmission. Its transmission principle is "total internal reflection of light." In the modern communications industry, optical fiber is widely used due to its low signal loss and high transmission efficiency. In addition, optical fiber is also widely used in other fields, such as laser therapy in the medical field, laser therapy for pets, and laser therapy for beauty. When using optical fiber, it is often necessary to connect the optical fiber to optical equipment through an optical fiber connector.

[0003] Although there are various types of medical fiber optic connectors available today, certain problems still exist. For example, while current fiber optic connectors can connect optical fibers to optical equipment, they need to be removed when not in use or when the optical equipment connected to the fiber needs to be replaced. At this time, the optical fiber on the connector will be exposed to the external environment, making it easy for the exposed fiber to accumulate dust in the air, which will affect the transmission performance of the fiber. Although some fiber optic connectors are equipped with protective structures such as dust caps, the dust caps need to be manually inserted and removed. During the insertion and removal process, the exposed fiber may also be damaged due to accidental contact, resulting in unnecessary economic losses. Utility Model Content

[0004] To address the problem that exposed optical fibers on current fiber optic connectors cannot be effectively protected, this application provides a medical fiber optic connector.

[0005] The medical fiber optic connector provided in this application adopts the following technical solution:

[0006] Medical fiber optic connectors, including:

[0007] An optical fiber outer tube, wherein an optical fiber bundle is disposed inside the optical fiber outer tube, and a portion of the optical fiber bundle is exposed at one end of the optical fiber outer tube;

[0008] An optical fiber protection mechanism is used to protect the optical fiber bundle. The optical fiber protection mechanism is slidably connected to the outer tube of the optical fiber. The optical fiber protection mechanism includes a protective sleeve, an isolation plate, a linkage toothed disc, and a rack. The protective sleeve is slidably sleeved on the outside of the outer tube of the optical fiber and is located at one end of the outer tube that exposes the optical fiber bundle. The isolation plate is rotatably connected inside the protective sleeve at one end away from the outer tube of the optical fiber. The linkage toothed disc is disposed on the isolation plate at the connection end with the protective sleeve. The rack is fixed on the outer tube of the optical fiber at one end near the protective sleeve and is located inside the protective sleeve. The linkage toothed disc and the rack mesh.

[0009] A limiting and locking mechanism is used to limit and lock the protective sleeve on the outer tube of the optical fiber, and the limiting and locking mechanism is disposed at one end of the protective sleeve.

[0010] By adopting the above technical solution and utilizing the optical fiber protection mechanism, one end of the protective sleeve is isolated from the external environment through the isolation plate, thereby achieving the protection effect of the optical fiber bundle and preventing the optical fiber bundle from being exposed to the external environment. At the same time, through the setting of the linkage toothed disc, toothed rack and other structures, the linkage toothed disc can engage with the toothed rack during the sliding of the protective sleeve on the outer tube of the optical fiber, thereby driving the isolation plate to rotate and avoiding direct contact with the optical fiber bundle, which could lead to damage to the optical fiber bundle.

[0011] By utilizing the limit locking mechanism, after the protective sleeve slides to the appropriate position on the outer tube of the optical fiber, the limit locking mechanism can connect and lock with the protective sleeve, thereby achieving the effect of limiting and locking the position of the protective sleeve. This facilitates the docking between the optical fiber bundle and medical optical equipment, and is simple, efficient and practical.

[0012] Optionally, the protective sleeve has a spherical cavity inside, and the isolation plate has an arc-shaped structure, with one side of the isolation plate abutting against the rack.

[0013] By adopting the above technical solution, the spherical cavity allows the arc-shaped isolation plate to slide inside the protective sleeve.

[0014] Optionally, the limiting and locking mechanism includes a limiting seat, a transmission plate, and a clamping plate. The limiting seat is fixed to the protective sleeve at one end away from the isolation plate, and the limiting seat is slidably sleeved on the outer tube of the optical fiber. An installation cavity is provided inside the limiting seat. The transmission plate is rotatably connected to the installation cavity of the limiting seat. The clamping plate is slidably engaged in the installation cavity of the limiting seat, and one end of the clamping plate is slidably connected to the transmission plate. The end of the clamping plate away from the transmission plate abuts against the outer wall of the outer tube of the optical fiber.

[0015] By adopting the above technical solution, the clamp is used to abut against the outer tube of the optical fiber, thereby locking the protective sleeve onto the outer tube of the optical fiber and preventing it from slipping.

[0016] Optionally, a pressing plate is slidably connected inside the limiting seat, the pressing plate is located outside the limiting seat, and the end of the transmission plate away from the clamping plate is slidably engaged with the pressing plate.

[0017] By adopting the above technical solution, the setting of the pressing plate enables the staff to quickly drive the transmission plate in linkage, and then quickly adjust the position of the clamping plate through the transmission plate.

[0018] Optionally, the inner wall of the mounting cavity of the limiting seat is provided with a reset member, one end of which abuts against the clamping plate.

[0019] By adopting the above technical solution, the elastic force of the reset component pushes the clamping plate, enabling the clamping plate to be quickly reset while also firmly abutting against the outer tube of the optical fiber.

[0020] Optionally, the integrated structure composed of the transmission plate, clamping plate and pressing plate is provided in multiple sets at equal intervals within the mounting cavity of the limiting seat.

[0021] By adopting the above technical solution, multiple clamps are used to firmly lock the limiting seat and the outer tube of the optical fiber.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] By utilizing the fiber optic protection mechanism, one end of the protective sleeve is isolated from the external environment via an isolation plate, thus protecting the fiber optic bundle and preventing it from being exposed. Simultaneously, the linkage gear plate and rack structure allow the protective sleeve to slide on the fiber optic outer tube, engaging with the rack to rotate the isolation plate and prevent direct contact with the fiber optic bundle, thus avoiding damage. Finally, a limiting and locking mechanism engages with the protective sleeve after it slides to the appropriate position, ensuring proper positioning and facilitating the connection between the fiber optic bundle and medical optical equipment. This design is simple, efficient, and practical. Attached Figure Description

[0033] Reference Figure 1 and Figure 2 The medical fiber optic connector includes an outer fiber optic tube 1, a fiber optic bundle 2, a fiber optic protection mechanism 3, and a limiting and locking mechanism 4. The fiber optic bundle 2 is housed inside the outer fiber optic tube 1, with a portion of the bundle 2 exposed at one end. The fiber optic protection mechanism 3, used to protect the fiber optic bundle 2, is slidably connected to the outer fiber optic tube 1. The limiting and locking mechanism 4 is located at one end of the protective sleeve 31. The fiber optic protection mechanism 3 isolates the fiber optic bundle 2 from the external environment, thus protecting it from exposure. Simultaneously, the internal linkage structure of the fiber optic protection mechanism 3 allows it to move synchronously along the outer fiber optic tube 1, preventing direct contact with the fiber optic bundle 2 and potential damage. The limiting and locking mechanism 4 effectively locks the position of the fiber optic protection mechanism 3, facilitating the connection between the fiber optic bundle 2 and medical optical equipment. This design is simple, efficient, and practical.

[0034] Reference Figure 3Specifically, in this embodiment of the application, the fiber optic protection mechanism 3 includes a protective sleeve 31, an isolation plate 32, a linkage toothed disc 33, and a rack 34. The protective sleeve 31 is slidably sleeved on the outside of the fiber optic outer tube 1 and is located at one end of the exposed fiber bundle 2 on the fiber optic outer tube 1. The isolation plate 32 is rotatably connected to the end of the protective sleeve 31 away from the fiber optic outer tube 1. The linkage toothed disc 33 is disposed on the connection end of the isolation plate 32 with the protective sleeve 31. The rack 34 is fixed on the end of the fiber optic outer tube 1 near the protective sleeve 31 and is located inside the protective sleeve 31. The linkage toothed disc 33 and the rack 34 mesh.

[0035] In this embodiment of the application, the protective sleeve 31 has a spherical cavity inside, and the isolation plate 32 has an arc-shaped structure. One side of the isolation plate 32 abuts against the rack 34, and the spherical cavity allows the arc-shaped isolation plate 32 to slide inside the protective sleeve 31.

[0036] Reference Figure 4 Specifically, in this embodiment, the limiting locking mechanism 4 includes a limiting seat 41, a transmission plate 42, a clamping plate 43, a pressing plate 44, and a reset member 45. By using the limiting locking mechanism 4, after the protective sleeve 31 slides to an appropriate position on the optical fiber outer tube 1, the limiting locking mechanism 4 can connect and lock with the protective sleeve 31, thereby achieving the limiting locking effect on the position of the protective sleeve 31, which facilitates the docking between the optical fiber bundle 2 and medical optical equipment. It is simple, efficient, and practical.

[0037] In this embodiment, the limiting seat 41 is fixed on the protective sleeve 31 at the end away from the isolation plate 32, and the limiting seat 41 is slidably sleeved on the optical fiber outer tube 1. An installation cavity is provided inside the limiting seat 41. The transmission plate 42 is rotatably connected in the installation cavity of the limiting seat 41. The clamping plate 43 is slidably engaged in the installation cavity of the limiting seat 41, and one end of the clamping plate 43 is slidably connected to the transmission plate 42. The end of the clamping plate 43 away from the transmission plate 42 abuts against the outer wall of the optical fiber outer tube 1. A pressing plate 44 is slidably connected inside the limiting seat 41. The pressing plate 44 is partially located outside the limiting seat 41, and the end of the transmission plate 42 away from the clamping plate 43 is slidably engaged with the pressing plate 44. A reset member 45 is provided on the inner wall of the installation cavity of the limiting seat 41, and one end of the reset member 45 abuts against the clamping plate 43.

[0038] In this embodiment, the overall structure composed of the transmission plate 42, the clamping plate 43 and the pressing plate 44 is provided in multiple sets at equal intervals in the mounting cavity of the limiting seat 41, and the limiting seat 41 and the optical fiber outer tube 1 can be firmly locked by the multiple clamping plates 43.

[0039] The implementation principle of the medical fiber optic connector in this application embodiment is as follows: When it is necessary to connect the fiber optic bundle 2 to the medical optical equipment, first push the pressing plate 44 to drive the transmission plate 42 to move together. The transmission plate 42 drives the clamping plate 43 to slide, so that one end of the clamping plate 43 is separated from the fiber optic outer tube 1. At this time, the sliding protective sleeve 31 and the limiting seat 41 are integrated. While sliding, the linkage gear 33 meshes with the rack 34. At this time, the isolation plate 32 rotates inside the isolation plate 32, and the fiber optic bundle 2 is exposed. Then, the pressing plate 44 is released, and the clamping plate 43 abuts against the fiber optic outer tube 1 under the elastic force of the reset member 45, thereby locking the position of the protective sleeve 31.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
