Description

Technical Field

[0001] This utility model relates to the field of biophotonics technology, and in particular to a protective quick-connect device for image transmission fiber bundles. Background Technology

[0002] Image-transmitting optical fibers are widely used in biophotonics due to their flexibility. The method of use involves positioning the incident surface of the image-transmitting fiber at the correct position and angle, allowing the laser beam to be directly incident onto the fiber's incident surface for coupling. During coupling, the fiber's geometric position and angle relative to the optical axis significantly affect the beam transmission quality and efficiency; even slight deviations can lead to a substantial increase in transmission loss or an uneven beam pattern.

[0003] Defects and shortcomings of existing technology:

[0004] Existing fiber optic alignment devices typically use various adjustable optical supports and clamps to fix the fiber optic cable, and then determine whether the fiber optic cable is aligned by observing the position of the laser beam projected onto the optical surface of the fiber optic cable by rotating a fine-tuning screw. This method is inefficient, the equipment is usually in an open state, and cannot effectively protect against laser damage. Furthermore, the device is bulky and inconvenient to carry and transport. Therefore, it is necessary to design a small-sized, quick-connect protective device for image transmission fiber optic bundles that facilitates rapid fiber optic alignment and protection. Utility Model Content

[0005] In order to overcome the shortcomings of existing fiber optic alignment devices, such as low alignment efficiency, open operation, inability to effectively protect against lasers, large size, and inconvenience in carrying and transporting, one of the objectives of this utility model is to provide a protective quick-connect device for image transmission fiber bundles.

[0006] One of the objectives of this utility model is achieved through the following technical solution: a protective quick-connect device for image transmission fiber bundles, comprising a hollow female end, a locking mechanism, and a sliding mechanism: the locking mechanism is disposed on one side of the hollow female end, the sliding mechanism is slidably connected to the inner wall of the hollow female end, the locking mechanism includes a ball bearing and an elastic wing, the sliding mechanism includes a sliding sleeve, the upper surface of the sliding sleeve is symmetrically provided with a first groove, the inner wall of the first groove is slidably connected with a sliding rod, one side of the sliding mechanism is movably connected with a spring, a fixed sleeve is installed on the inner wall of the hollow female end near the sliding mechanism, the outer surface of the fixed sleeve is symmetrically provided with a second groove; the sliding rod is slidably connected to the second groove, one end of the spring is fixedly connected to the inner wall of one side of the fixed sleeve, the inner wall of the hollow female end is installed with a male fiber end, one end of the male fiber end is a conical surface, and the outer surface of the male fiber end is symmetrically provided with limiting planes. The sliding mechanism facilitates quick fiber optic connection and opening for use, and also allows for laser protection when not in use. Meanwhile, the locking mechanism can adjust the stability of the male fiber optic end installed in the hollow female end, effectively improving the accuracy and efficiency of fiber optic connection.

[0007] According to the aforementioned protective quick-connect device for image transmission fiber bundles, the hollow female end has symmetrically formed through holes on the inner wall of the side near the male end of the fiber. A ball bearing is movably connected to the inner wall of the through hole, and an elastic wing is mounted on the outer surface of the hollow female end, with the elastic wing and the ball bearing being movably connected. This facilitates adjustment of the ball bearing's locking force.

[0008] According to the protective quick-connect device for image transmission fiber bundles, the hollow female end, the locking mechanism, and the sliding mechanism are detachable and assembleable, facilitating maintenance and replacement of damaged components.

[0009] According to the aforementioned protective quick-connect device for image transmission fiber bundles, the size of the sliding sleeve is adapted to the size of the hollow female end and the inner wall of the fixed sleeve. This facilitates the sliding sleeve sliding within the inner walls of the fixed sleeve and the hollow female end, enabling opening and closing actions.

[0010] According to the aforementioned protective quick-connect device for image transmission fiber bundles, the inner wall of the sliding sleeve is provided with an abutment surface, the size of which is adapted to the size of the conical surface. This facilitates the movement of the sliding sleeve by the male end of the optical fiber.

[0011] According to the aforementioned protective quick-connect device for image transmission fiber bundles, the outer surface of the fixing sleeve near the hollow female end has a first threaded groove, and the inner wall of the hollow female end near the first threaded groove has a second threaded groove. The fixing sleeve and the hollow female end are connected through the first threaded groove and the second threaded groove. This facilitates the assembly and use of the fixing sleeve and the hollow female end together.

[0012] According to the aforementioned protective quick-connect device for image transmission fiber bundles, a protective shell is screwed onto the outer surface of the hollow female end near the sliding mechanism. A mounting rod is symmetrically arranged on the side of the fixing sleeve near the protective shell, the mounting rod penetrating one side of the protective shell, and the protective shell is mounted on the outer surface of the fixing sleeve via the mounting rod. This facilitates the protection of the sliding mechanism.

[0013] According to the protective quick-connect device for image transmission fiber bundles, a limiting block is fixedly connected to one inner wall of the protective shell, and the limiting block is disposed above the sliding mechanism. This facilitates the limiting and protection of the sliding rod's position, preventing the sliding rod from sliding out or falling off.

[0014] The above-mentioned solution has the following beneficial effects:

[0015] 1. Through the setting of locking mechanism, sliding mechanism, spring, optical fiber male end and hollow female end, the optical fiber male end pushes the sliding sleeve to make the two sliding rods move in opposite directions to realize the door opening action. When the optical fiber male end is moved out, the spring resets the position of the sliding sleeve and makes the two sliding rods move towards each other, thereby realizing the protective door closing action. At the same time, the locking mechanism adjusts the stability of the optical fiber male end installed in the hollow female end, which facilitates rapid coupling of optical fibers and facilitates laser protection when not in use, thereby effectively improving the accuracy and efficiency of optical fiber splicing.

[0016] 2. With the locking mechanism, sliding mechanism, fixed sleeve and hollow female end, the locking mechanism, sliding mechanism, fixed sleeve and hollow female end are detachable and assembleable. The assembly form allows for individual replacement and repair when a component is damaged, thereby reducing the maintenance cost of the device and improving maintenance efficiency. In addition, the device is small in size and easy to carry and transport.

On the outer surface of the hollow female end 1, the elastic wing 22 is movably connected to the ball 21. The hollow female end 1, the locking mechanism 2, and the sliding mechanism 3 are detachable assembly structures. The size of the sliding sleeve 31 is adapted to the size of the inner wall of the hollow female end 1 and the fixed sleeve 5. The inner wall of the sliding sleeve 31 is provided with an abutment surface 10, the size of which is adapted to the size of the conical surface. The outer surface of the fixed sleeve 5 near the hollow female end 1 is provided with a threaded groove 11, and the inner wall of the hollow female end 1 near the threaded groove 11 is provided with a threaded groove 11. The device has a second threaded groove 12. The fixed sleeve 5 and the hollow female end 1 are connected by the first threaded groove 11 and the second threaded groove 12. A protective shell 13 is screwed on the outer surface of the hollow female end 1 near the sliding mechanism 3.

[0028] Working principle: After initial debugging, a mechanical reference hole is established for the laser output optical axis. This allows the fiber to be quickly aligned with the beam by direct insertion into this device when coupling is required. For rapid fiber coupling, the tapered end of the male fiber 7 is inserted into the hollow female end 1, and the two limiting planes 8 contact the ball bearing 21. The tapered surface of the male fiber 7 abuts against the contact surface 10 of the sliding sleeve 31, pushing the sliding sleeve 31 to move within the hollow female end 1 and the fixed sleeve 5. Simultaneously, the movement of the sliding sleeve 31 drives the two sliding rods 33 to move in opposite directions within the inner walls of the first and second sliding grooves 32 and 6, thus moving the two sliding rods 33 to the sides to achieve the opening action. Afterwards, the elastic wing 22 adjusts the contact between the ball bearing 21 and the limiting plane. The locking force of the contact plane 8 ensures that the male end 7 of the optical fiber is securely installed inside the hollow female end 1, facilitating rapid coupling of the optical fiber to the aligned beam. When coupling is not required, the locking force of the ball bearing 21 is adjusted by the elastic wing 22 to release the male end 7 of the optical fiber, allowing it to be removed from the hollow female end 1. At this time, the sliding mechanism 3 automatically resets via the spring 4, and the two sliding rods 33 move towards each other to make contact, thereby achieving the closing protection action. This solves the problem that the device cannot effectively perform laser protection when not in use. It is easy to use, facilitates rapid coupling and disassembly of optical fibers for precise docking and protection, effectively improves docking efficiency, and the device is small in size, easy to carry, and convenient for transportation.
