Description

Technical Field

[0001] The present application relates to the technical field of lasers, and in particular to a portable optical fiber winding reel. Background Art

[0002] Before laser products are shipped or undergo quality inspection, their optical fibers need to be coiled and fixed to facilitate packaging or inspection.

[0003] Traditional fiber optic winding is done manually. After winding N circles, the end of the wire is passed through the circle to keep it relatively fixed in a loop. However, due to the different sizes and strengths of human hands, it is easy to break the fiber optic cable, and the circles are also of different sizes. Or the winding is done by a jig, such as the winding drum used for daily needlework. However, when using it, the optical fiber is tightly attached to the outer wall of the winding drum, which makes it inconvenient to thread and remove the wire after winding the circle, making it inconvenient to use. Summary of the invention

[0004] In order to facilitate optical fiber winding, the present application provides a convenient optical fiber winding reel.

[0005] The present application provides a portable optical fiber winding reel adopting the following technical solution: A portable optical fiber winding reel comprises a base, a reel body is arranged on the base, the side wall of the reel body is in an arc shape, at least one threading groove concave in the radial direction of the reel body is opened on the side wall of the reel body, and a mounting plate for mounting a laser is detachably connected to the top of the reel body.

[0006] By adopting the above technical solution, the operator installs the laser on the mounting plate, holds the end of the optical fiber and winds the optical fiber around the side wall of the disc, and finally passes the end of the optical fiber through the threading groove, removes the laser from the mounting plate, and then removes the mounting plate from the disc, and then the wound optical fiber connected to the laser can be taken out from the disc. In this way, it is convenient to wind the optical fiber, and it is also convenient to remove the optical fiber and the mold after winding, which is convenient to use.

[0007] Preferably, a limiting groove penetrating the mounting plate is formed at one end of the mounting plate, and an opening of the limiting groove is communicated with an end portion of the mounting plate.

[0008] By adopting the above technical solution, the optical fiber passes through the limiting groove and then is wound on the disc body. The limiting groove limits and guides the optical fiber to ensure the winding effect.

[0009] Preferably, the mounting plate is provided with at least one strip-shaped mounting groove, the direction of the mounting groove is consistent with the direction of the limiting groove, and a plurality of mounting posts corresponding to the mounting grooves are fixed on the top of the disk body, the mounting posts are passed through the mounting grooves, and when the mounting posts are located at the end of the mounting groove close to the limiting groove, the end of the mounting plate with the limiting groove is retracted above the disk body; when the mounting posts are located at the end of the mounting groove away from the limiting groove, the end of the mounting plate with the limiting groove extends out of the disk body from above the disk body.

[0010] By adopting the above technical solution, the mounting plate is connected to the disc body through the mounting column, and the mounting plate is easy to disassemble and assemble. When the mounting plate is mounted on the disc body, the end thereof extends out from the disc body, and the optical fiber passes through the limiting groove and is wound downward on the disc body. When winding, the mounting plate extending out of the disc body can limit and block the optical fiber to prevent the optical fiber from loosening from the disc body. After winding is completed, the mounting plate can be removed from the disc body by sliding, which is convenient to use.

[0011] Preferably, the base is provided with an annular track, the track is arranged concentrically with the disk body, the track diameter is larger than the disk body diameter, a winding rod is slidably connected to the track, and the winding rod is provided with a clamping hole for clamping the end of the optical fiber.

[0012] By adopting the above technical solution, the end of the optical fiber passes through the clamping hole, the winding rod slides along the track, and drives the optical fiber to be wound. The winding rod drives the optical fiber to be wound by itself, which is faster and more convenient to use.

[0013] Preferably, the winding rod includes a lower rod and an upper rod, the lower end of the lower rod is slidably connected in the track, the upper rod is slidably connected in the upper end of the lower rod, the clamping hole is opened on the upper rod, when the upper rod is located at the top, the axis of the clamping hole is not lower than the upper surface of the mounting plate, when the upper rod is located at the bottom, the axis of the clamping hole is located below the upper surface of the disk body.

[0014] By adopting the above technical solution, when the winding rod is in the initial state, the winding rod is opposite to the mounting plate, and the upper rod is located at the top, the clamping hole is opposite to the optical fiber, and the operator passes the optical fiber through the clamping hole. Press the upper rod downward so that the clamping hole is located below the mounting plate and opposite to the side wall of the disk body, the winding rod moves along the track, and the optical fiber is wound on the side wall of the disk body, ensuring the winding effect of the optical fiber.

[0015] Preferably, a plurality of ratchets are vertically arranged at the lower end of the upper rod, and the ratchets include a limiting plane and a sliding inclined plane, and the sliding inclined plane is located below the limiting plane. A rotating rod is rotatably connected to the lower rod, and a pawl matching with the ratchets is fixed on the rotating rod. A limiting torsion spring is provided between the rotating rod and the lower rod, and when the limiting torsion spring is in a natural state, the pawl contacts the limiting plane. A reset spring is provided between the upper rod and the lower rod, and when the reset spring is in a natural state, the upper rod is located at the top.

[0016] By adopting the above technical solution, the ratchet and the pawl cooperate to limit the movement direction of the upper rod, and the operator can press the upper rod downward, and the upper rod cannot rise by itself due to the cooperation of the ratchet and the pawl, thereby preventing the upper rod from rising to the highest position by itself during the process of winding the optical fiber and affecting the winding effect of the optical fiber.

[0017] Preferably, the end of the rotating rod away from the pawl passes through the lower rod and is fixed with a lever located in the track, and a trigger rod is fixed in the track. The position of the track facing the end of the mounting plate away from the laser is the starting point, and the direction of the trigger rod toward the starting point is consistent with the movement direction of the winding rod. When the trigger rod contacts the lever, the trigger rod drives the pawl to rotate in the direction away from the upper rod.

[0018] By adopting the above technical solution, when the upper rod is at the bottom, it starts to move along the track from the starting point to wind the optical fiber. When the winding rod moves one circle and returns to the starting point again, the trigger rod will contact the lever, and the winding rod continues to move. The trigger rod contacts the lever, and when the lever passes the trigger rod, the lever rotates under the pressure of the trigger rod, thereby driving the rotating rod and the pawl to rotate, so that the pawl is disengaged from the ratchet. At this time, the upper rod is lifted upward under the action of the reset spring, and when the lever passes the trigger rod, the rotating rod and the pawl are reset under the action of the limit torsion spring to contact and cooperate with the ratchet again, and the ratchet is limited, and the upper rod is limited again and cannot continue to move up. That is, when the upper rod completes a circle of optical fiber and passes the starting point again, it will move up a distance under the action of the trigger rod. When the upper rod continues to drive the optical fiber to wind the next circle, the winding position of the optical fiber will be higher than the position of the optical fiber in the previous circle, so that the optical fiber is spirally wound on the side wall of the disk as a whole, preventing all the optical fibers from being stacked in one place and affecting the winding effect.

[0019] Preferably, a limiting rod is fixed on the lower rod, and the limiting rod is located on a side of the pawl close to the upper rod. When the limiting torsion spring is in a natural state, the pawl contacts the limiting rod.

[0020] By adopting the above technical solution, the limiting rod limits the pawl, thereby ensuring the limiting effect of the pawl on the ratchet teeth.

[0021] Preferably, an elastic clamping sleeve is provided in the clamping hole, a conical hole is opened in the center of the clamping sleeve, the end with the larger aperture of the conical hole faces the disk body, the diameter of the end with the larger aperture of the conical hole is larger than the diameter of the optical fiber, and the diameter of the end with the smaller aperture is smaller than the diameter of the optical fiber.

[0022] By adopting the above technical solution, the clamping sleeve clamps and fixes the optical fiber, and the optical fiber is directly plugged into the clamping sleeve, which is convenient to use.

[0023] Preferably, a motor is provided on the winding rod, and a roller rolling in a track is connected to the output shaft of the motor. A trigger switch is provided in the lower rod, and the trigger switch is electrically connected to the motor. When the upper rod is at the bottom, the trigger switch contacts the upper rod.

[0024] By adopting the above technical solution, when the winding rod is in the initial state, it is located at the mounting plate, and the upper rod is located at the top. After the optical fiber is installed on the upper rod, the operator presses the upper rod downward until the upper rod is at the bottom, the trigger switch contacts the upper rod, and the motor is activated. At this time, the motor can be started, and the winding rod moves along the track to wind the optical fiber. If the upper rod is not pressed to the bottom, the trigger switch cannot be triggered, the motor cannot be started, and the winding rod cannot move. The trigger switch serves as a protective measure to ensure that the upper rod is at the bottom before winding can be performed, thereby ensuring the overall winding effect.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: Through the setting of the threading grooves on the mounting plate and the side wall of the tray, the operator can conveniently wind the optical fiber on the side wall of the tray, and can pass the end of the optical fiber through the threading groove, which is convenient for pulling out the wire end when it is used again later, and also convenient for winding the optical fiber and separating it from the tray, which is easy to use; Through the setting of the winding rod, the optical fiber can be automatically wound, saving the operator the inconvenience of manual winding; By setting the upper rod and the lower rod, when the winding rod drives the optical fiber for winding, the optical fiber can be spirally wound on the side wall of the disk body, thereby preventing the optical fiber from stacking and ensuring the winding effect of the optical fiber.

[0028] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0029] Embodiment 1

[0030] The present application embodiment discloses a portable optical fiber winding reel, referring to Figure 1 , including a base 1, a disc body 2 and a mounting plate 3. The disc body 2 is fixed on the base 1, the base 1 has a diameter larger than the disc body 2, the mounting plate 3 is detachably connected to the upper surface of the disc body 2, and the laser is mounted on the mounting plate 3.

[0031] Reference Figure 1 , the side wall of the disk body 2 is in an arc shape, and the optical fiber is wound on the side wall of the disk body 2. At least one threading groove 21 is provided on both sides of the side wall of the disk body 2, and is concave in the radial direction of the disk body 2. In this embodiment, two threading grooves 21 are provided. That is, the side wall of the disk body 2 is divided into four parts, two threading grooves 21 that are concave inwardly, and two side walls that are protruding outwardly in an arc shape, and the connection is an arc transition to protect the optical fiber. When the optical fiber is wound on the outer wall of the disk body 2, the optical fiber collides with the arc-shaped side wall, and a gap is left between the optical fiber and the threading groove 21. When the optical fiber is wound, the end of the light is passed through the threading groove 21, so that it is convenient to find the thread end when it is used later.

[0032] Reference Figure 1 A plurality of upwardly protruding mounting posts 22 are fixed on the upper surface of the disk body 2, and the mounting posts 22 are arranged along the radial direction of the disk body 2. A plurality of mounting grooves 32 corresponding to the mounting posts 22 are provided on the mounting plate 3, and the mounting grooves 32 are arranged in strips and the direction of the mounting grooves 32 is consistent with the arrangement direction of the mounting posts 22. The mounting plate 3 is slidably connected to the disk body 2 through the mounting posts 22.

[0033] Reference Figure 1, a limiting groove 31 penetrating the mounting plate 3 is provided at one end of the mounting plate 3, the opening of the limiting groove 31 is connected to the end of the mounting plate 3, and the edge of the limiting groove 31 is rounded to protect the optical fiber. The limiting groove 31 is arranged in a strip shape, and the direction of the limiting groove 31 is consistent with the direction of the mounting groove 32. When the mounting column 22 is located at the end of the mounting groove 32 close to the limiting groove 31, the end of the mounting plate 3 provided with the limiting groove 31 is retracted above the disk body 2. When the mounting column 22 is located at the end of the mounting groove 32 away from the limiting groove 31, the end of the mounting plate 3 provided with the limiting groove 31 extends from the top of the disk body 2 to the disk body 2.

[0034] The implementation principle of a portable optical fiber winding reel in an embodiment of the present application is as follows: the mounting plate 3 mounting column 22 is on the reel body 2, and the mounting column 22 is located at the end of the mounting slot 32 close to the limiting slot 31. At this time, the opening portion of the limiting slot 31 extends out of the reel body 2. The laser is mounted on the mounting plate 3 by means of bolts or the like, and the optical fiber passes through the limiting slot 31 and is wound downward on the side wall of the reel body 2. The portion of the mounting plate 3 extending out of the reel body 2 blocks and limits the optical fiber to prevent the optical fiber from escaping from the top of the reel body 2 during the winding process. After the winding is completed, pass the end of the optical fiber through the threading slot 21. Remove the laser from the mounting plate 3, remove the mounting plate 3 from the reel body 2, and then remove the wound optical fiber from the reel body 2.

[0035] Embodiment 2

[0036] The difference between the second embodiment and the first embodiment is that the structure of the base 1 is different: Figure 2 The base 1 is provided with an annular track 11 which is concentric with the disc body 2, and the diameter of the track 11 is larger than the diameter of the disc body 2. A winding rod 4 is movably connected in the track 11, and the winding rod 4 clamps the optical fiber so as to drive the optical fiber to be automatically wound.

[0037] Reference Figure 2 and Figure 3 The winding rod 4 includes an upper rod 41 and a lower rod 42. The lower rod 42 is hollow, and the upper rod 41 is vertically slidably connected to the lower rod 42. A horizontally arranged clamping hole 411 is provided at the upper end of the upper rod 41. An elastic clamping sleeve 412 is installed in the clamping hole 411. A conical hole is provided in the center of the clamping sleeve 412. The end with a larger aperture of the conical hole faces the disk body 2. The diameter of the end with a larger aperture of the conical hole is larger than the diameter of the optical fiber, and the diameter of the end with a smaller aperture is smaller than the diameter of the optical fiber. The optical fiber passes through the clamping sleeve 412 from the end with a larger aperture of the conical hole and passes out from the other end. The clamping sleeve 412 clamps the optical fiber. The upper rod 41 drives the optical fiber to be wound. After the winding is completed, the optical fiber can be pulled out of the clamping sleeve 412, which is convenient to use.

[0038] Reference Figures 2 to 4When the upper rod 41 is at the top, the axis of the clamping hole 411 is not lower than the upper surface of the mounting plate 3. When the upper rod 41 is at the bottom, the axis of the clamping hole 411 is located below the upper surface of the disk body 2 and faces the side wall of the disk body 2. When the winding rod 4 is in the initial position, the winding rod 4 is directly opposite to the limit groove 31, and the upper rod 41 is at the top. At this time, the end of the optical fiber is inserted into the clamping sleeve 412, and the upper rod 41 is pressed to the bottom, and the end of the optical fiber is aligned with the side wall of the disk body 2. At this time, the winding rod 4 starts to move along the track 11, and the upper rod 41 drives the optical fiber to be wound.

[0039] Reference Figures 2 to 4 A plurality of ratchets 43 distributed in vertical strips are fixed at the lower end of the upper rod 41. The ratchets 43 include a limiting plane 431 and a sliding inclined surface 432. The sliding inclined surface 432 is located below the limiting plane 431. A rotating rod 44 that penetrates the inner cavity and outer wall of the lower rod 42 is rotatably connected to the lower rod 42. A ratchet 45 that matches the ratchet 43 is fixed to the end of the rotating rod 44 located in the inner cavity of the lower rod 42. A limiting torsion spring 46 is provided between the rotating rod 44 and the lower rod 42. When the limiting torsion spring 46 is in a natural state, the ratchet 45 contacts the limiting plane 431. When the upper rod 41 slides downward, the ratchet 43 moves downward, the sliding inclined surface 432 contacts the upper end of the ratchet 45, and squeezes the ratchet 45 to rotate downward until the ratchet 45 passes over the ratchet 43 and contacts the limiting plane 431 of the ratchet 43.

[0040] Reference Figures 2 to 4 A limiting rod 49 is fixed on the lower rod 42, and the limiting rod 49 is located on the side of the pawl 45 close to the upper rod 41. When the limiting torsion spring 46 is in a natural state, the pawl 45 contacts the limiting rod 49. The limiting rod 49 limits the rotation direction of the pawl 45. When the pawl 45 contacts the limiting plane 431, the upper rod 41 moves upward, and the limiting plane 431 applies an upward driving force to the pawl 45, while the pawl 45 is limited by the limiting rod 49 and cannot rotate, thereby limiting the upper rod 41 from moving upward.

[0041] Reference Figures 2 to 5 , a lever 48 located in the track 11 is fixed to the end of the rotating rod 44 located on the outer wall of the lower rod 42. The position where the track 11 is opposite to the limit groove 31 is the starting point. The winding rod 4 clamps the optical fiber at the starting point and moves in one direction along the track 11 to start winding. A trigger rod 111 is fixed in the track 11. There are two arc tracks, one long and one short, between the trigger rod 111 and the starting point. The direction of the trigger rod 111 toward the starting point along the shorter arc track is consistent with the movement direction of the winding rod 4, and the length of the shorter arc track is much shorter than the longer arc track. When the trigger rod 111 contacts the lever 48, the trigger rod 111 drives the pawl 45 to rotate in the direction away from the limit rod 49. A reset spring 47 is provided between the upper rod 41 and the lower rod 42. When the reset spring 47 is in a natural state, the upper rod 41 is located at the top.

[0042] Reference Figures 2 to 5 When the upper rod 41 drives the optical fiber to be wound, due to the action of the ratchet 43 and the pawl 45, the upper rod 41 cannot move upward by the return spring 47, thereby preventing the upper rod 41 from sliding by itself during the winding process, thereby affecting the winding effect of the optical fiber. The optical fiber is usually wound more than once and needs to be wound multiple times. If the optical fiber is wound at the same position, the optical fiber is easy to be staggered and knotted, affecting subsequent use.

[0043] Reference Figures 2 to 5 , the winding rod 4 starts from the starting point to wind the optical fiber along a longer arc track until it moves to the trigger rod 111. The lever 48 will contact the trigger rod 111. As the winding rod 4 continues to move, the trigger rod 111 contacts the lever 48. The lever 48 will rotate under the action of the trigger rod 111. The lever 48 drives the pawl 45 to flip downward and disengage from the ratchet 43 through the rotating rod 44. At this time, the upper rod 41 will rise under the action of the reset spring 47. After the lever 48 passes over the trigger rod 111, the rotating rod 44 rotates upward under the action of the limit torsion spring 46 to reset. The pawl 45 cooperates with the ratchet 43 again, and the upper rod 41 is again restricted from rising. During the period when the pawl 45 separates from the ratchet 43 and resets, the upper rod 41 rises a distance slightly greater than the diameter of the optical fiber.

[0044] Reference Figures 2 to 5 Each time the upper rod 41 winds the optical fiber around one circle and then goes around the next circle, it will move up a certain distance under the action of the trigger rod 111. When the upper rod 41 continues to drive the optical fiber to wind the next circle, the winding position of the optical fiber will be higher than the position of the optical fiber in the previous circle, so that the optical fiber is spirally wound on the side wall of the disk body 2 as a whole, preventing all the optical fibers from being stacked in one place and affecting the winding effect.

[0045] Reference Figure 2 and Figure 3 A motor 5 is installed at the lower end of the lower rod 42, and a roller 6 rolling in the track 11 is connected to the output shaft of the motor 5. A trigger switch 421 is provided in the lower rod 42, and the trigger switch 421 is electrically connected to the motor 5. When the upper rod 41 is at the bottom, the trigger switch 421 contacts the upper rod 41.

[0046] Reference Figure 2 and Figure 3After the optical fiber is installed on the upper rod 41, the operator presses the upper rod 41 downward until the upper rod 41 is at the bottom, the trigger switch 421 contacts the upper rod 41, and the motor 5 is activated. At this time, the motor 5 can be started, and the winding rod 4 moves along the track 11 to wind the optical fiber. If the upper rod 41 is not pressed to the bottom, the trigger switch 421 cannot be triggered, the motor 5 cannot be started, and the winding rod 4 cannot move. The trigger switch 421 serves as a protective measure to ensure that the upper rod 41 is at the bottom before winding, thereby ensuring the overall winding effect.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
