Description

Technical Field

[0001] This application relates to the technical field of trays, and in particular to a folding fiber optic cleaver tray. Background Technology

[0002] In the field of fiber optic communication construction and maintenance, the fiber optic cleaver, as one of the core tools, is often used in conjunction with a fiber optic fusion splicer. During operation, the cleaver usually needs to be temporarily placed in a stable position for easy switching by the operator. However, existing technologies generally lack dedicated and portable support devices, leading to the following problems: I. Installation and Portability Issues: Traditional pallets often use fixed structures or simple brackets, making them difficult to install quickly onto the side walls of equipment enclosures. They are also bulky, lack folding capabilities, and take up significant space when carried, impacting construction and relocation efficiency. Especially in confined working environments, the heavy pallets are ill-suited to the equipment layout requirements.

[0003] II. Stability Defects: Existing tray fixing methods mostly rely on screws or simple clips, which are prone to loosening or even falling off due to vibration or accidental contact, posing a risk of the cutting blade slipping and threatening operational safety. Although some designs use hinged structures, they lack reliable locking mechanisms, making them prone to wobbling after unfolding and affecting operational accuracy.

[0004] To address the aforementioned issues, there is an urgent need for a fiber optic cleaver tray that offers both rapid installation and stable support. Summary of the Invention

[0005] To facilitate stable support of the fiber optic cleaver and improve the ease of use of the fiber optic cleaver, this application provides a foldable fiber optic cleaver tray.

[0006] This application provides a foldable fiber optic cleaver tray, which adopts the following technical solution: A foldable fiber optic cleaver tray includes a connecting piece that is detachably connected to a housing. One end of the connecting piece is provided with a short buckle and a long buckle, the long buckle and the short buckle forming a hook space, the hook space being fastened to the edge of the housing. The connecting piece is provided with a locking component for connecting and fixing to the housing. The other end of the connecting piece is provided with a support tray, and the connecting piece is provided with a hinge mechanism for hinged and fixed to the support tray.

[0007] By adopting the above technical solution, when using a fiber optic cleaver in conjunction with a fiber optic fusion splicer, the tray needs to be installed on one side of the enclosure. First, the connecting piece is hung on the edge of the enclosure through the hook space, and then the connecting piece is locked in place by the locking component. Next, the tray is swung open so that the tray and the connecting piece are perpendicular to each other. Then, the tray is locked by the hinge mechanism. Finally, the fiber optic cleaver is placed on the tray for use with the fiber optic fusion splicer. The tray supports the fiber optic cleaver, which improves the convenience of using the fiber optic cleaver.

[0008] Optionally, the locking assembly includes a buckle and a lever. One end of the connecting piece has a groove, and one end of the buckle is fixedly connected to the groove wall. The side wall of the housing has a slot, and the buckle is inserted into the slot. The lever is disposed on the top surface of the other end of the buckle, and the side wall of the lever has a locking platform, which engages with the slot.

[0009] By adopting the above technical solution, when it is necessary to fix the connecting piece, while hooking the edge of the box in the hook space, the buckle is first fastened into the slot, and then the lever is used to drive the locking platform to be hooked into the slot. At this time, the connecting piece is fixed to the side wall of the box. Similarly, when it is necessary to release the connecting piece, the lever is driven to move away from the box. The lever drives the locking platform to disengage from the slot, and then the buckle is released from the slot and the hook space is released from the edge of the box in sequence, which helps to improve the convenience of the connecting piece's assembly and disassembly.

[0010] Optionally, the hinge mechanism includes a hinge shaft, a hinge groove is provided at the other end of the connecting piece, a hinge ear is provided on one side of the support tray, the hinge ear is rotatably disposed in the hinge groove, the hinge shaft passes through the other end of the connecting piece and the hinge ear in sequence, the hinge ear is slidably sleeved on the hinge shaft, and the connecting piece is provided with a fixing component for fixing the support tray.

[0011] By adopting the above technical solution, when the pallet needs to be unfolded and used, the pallet is first swung away from the connecting piece. The pallet then drives the hinge ear to rotate around the hinge axis. When the pallet and the connecting piece are perpendicular to each other, the pallet is finally fixed by the fixing component, which helps to improve the convenience of unfolding and fixing the pallet.

[0012] Optionally, the fixing component includes a spring, a fixing block is provided at the inner corner of the hinge groove, a fixing groove is provided on the side wall of the hinge ear, the fixing block is inserted into the fixing groove, the spring is sleeved on the hinge shaft, one end of the spring abuts against the groove wall of the hinge groove, and the other end of the spring abuts against the inner wall of the hinge ear.

[0013] By adopting the above technical solution, when the support tray and the connecting piece are folded together, the fixing block and the fixing groove are misaligned, and the hinge ear compresses the spring. When the support tray is unfolded and perpendicular to the connecting piece, the fixing block aligns with the fixing groove, and the spring releases its elastic force. The spring drives the hinge ear to move towards the fixing block, and the fixing block is inserted into the fixing groove. Under the pressing action of the spring and the limiting action of the fixing block, the support tray and the connecting piece are perpendicular to each other, and the support tray and the connecting piece are fixed to each other, which helps to improve the stability of the support tray fixed to one side of the connecting piece.

[0014] Optionally, the outer wall of the connecting piece is provided with a transmission seat, a material bag is extended from the outer side of the connecting piece, and skeleton rods are provided at both ends of the material bag. The transmission seat is provided with a swing mechanism for driving the skeleton rods to extend and swing.

[0015] By adopting the above technical solution, the material bag is loaded with the cut waste and tools. Under the action of the swing mechanism, when the support tray is unfolded, the support tray drives the material bag to unfold. Similarly, when the support tray is closed, the support tray drives the material bag to close, which helps to improve the convenience of using the material bag.

[0016] Optionally, the swing mechanism includes a telescopic rod and a swing arm. One end of the telescopic rod is hinged to the inner bottom end of the transmission seat. The skeleton rod is fixedly mounted on the side wall of the telescopic rod. A first gear is rotatably mounted on the inner top end of the transmission seat. One end of the swing arm is fixedly connected to the side wall of the first gear. The other end of the swing arm is hinged to the other end of the telescopic rod. The transmission seat is provided with a transmission component for driving the first gear to rotate.

[0017] By adopting the above technical solution, when the transmission component drives the first gear to rotate, the first gear drives the swing arm to swing outward, which in turn drives the telescopic rod to extend and swing outward simultaneously. The telescopic rod then drives the frame rod to swing outward, and the frame rod then unfolds the material bag. Similarly, when the first gear drives the swing arm to swing inward, the swing arm drives the telescopic rod to shorten and swing inward simultaneously. The telescopic rod then drives the frame rod to swing inward, and the frame rod then closes the material bag, thereby improving the stability of the opening and closing of the material bag.

[0018] Optionally, the transmission assembly includes a second gear and an arc tooth. The arc tooth is disposed on the outer wall of the hinge ear, and the second gear is rotatably disposed in the transmission seat. The first gear and the second gear mesh with each other, and the second gear meshes with the arc tooth.

[0019] By adopting the above technical solution, when the pallet is unfolded, the pallet drives the arc tooth to rotate through the hinge lug, the arc tooth drives the second gear to rotate, the second gear drives the first gear to rotate, the first gear drives the swing arm to swing, the swing arm drives the telescopic rod to swing, and the telescopic rod drives the material bag to unfold through the skeleton rod, which helps to improve the stability of the pallet driving the material bag to unfold or close synchronously.

[0020] Optionally, a relief groove is provided at the other end of the connecting piece, and the arc tooth is inserted into the relief groove.

[0021] By adopting the above technical solution, the clearance groove ensures that the arc teeth have enough space to rotate, ultimately improving the stability of the material bag when it opens or closes.

[0022] Optionally, the bottom surface of the tray is provided with a receiving groove, and the material bag and the transmission seat are both received in the receiving groove.

[0023] By adopting the above technical solution, when the pallet is unlocked and folded, the material bag and the transmission seat are both housed in the receiving slot, which helps to improve the pallet's ability to be fully folded, reduce space occupation, and improve carrying convenience.

[0024] In summary, this application includes the following beneficial technical effects: When using a fiber optic cleaver with a fiber optic fusion splicer, the tray needs to be installed on one side of the enclosure. First, the connecting piece is hung on the edge of the enclosure using the hook space, and then the connecting piece is secured using the locking assembly. Next, the tray is swung open so that the tray and the connecting piece are perpendicular to each other. Then, the tray is locked using the hinge mechanism. Finally, the fiber optic cleaver is placed on the tray for use with the fiber optic fusion splicer. The tray supports the fiber optic cleaver, which improves the ease of use of the cleaver.

[0027] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0028] See Figures 1-3 A foldable fiber optic cleaver tray includes a connecting piece 2 detachably connected to a housing 1. The housing 1 houses a fiber optic fusion splicer and is also covered by a cover 3. The connecting piece 2 has an L-shaped cross-section. One end of the connecting piece 2 has a short buckle 4 and a long buckle 5 integrally formed, which combine to form a U-shaped structure. The short buckle 4 and long buckle 5 enclose a hooking space 6, through which the connecting piece 2 is hooked to the edge of the housing 1. The connecting piece 2 is equipped with a locking assembly for fixing the connecting piece 2 to the side wall of the housing 1. The other end of the connecting piece 2 is equipped with a support tray 7 for supporting the fiber optic cleaver, allowing the fiber optic cleaver to be positioned close to the fiber optic fusion splicer. The connecting piece 2 is equipped with a hinge mechanism for hinged and fixed the support tray 7.

[0029] The core purpose of a fiber optic fusion splicer is to achieve high-precision fiber splicing. Before splicing, a fiber optic cleaver is used to cut thin, hair-like quartz glass fibers, ensuring a smooth and flat end. Therefore, when using the fiber optic cleaver with the fusion splicer, a tray needs to be installed on one side of the housing 1. First, the connecting piece 2 is hung on the edge of the housing 1 via the hook space 6, and then secured by the locking assembly. Next, the support tray 7 is swung open, making it perpendicular to the connecting piece 2. The support tray 7 is then locked by the hinge mechanism. Finally, the fiber optic cleaver is placed on the support tray 7 for use with the fusion splicer. The support tray 7 supports the fiber optic cleaver, thus improving its ease of use.

[0030] For details, see Figure 1 and Figure 3The locking assembly includes a buckle 8 and a lever 9. One end of the connecting piece 2 has a groove 10. The buckle 8 has a Z-shaped cross-section, and one end of the buckle 8 is fixedly connected to the inner wall of the groove 10. A slot 11 is formed on the side wall of the housing 1 corresponding to the position of the buckle 8, and the buckle 8 is inserted into the slot 11. The lever 9 is fixedly connected to the top surface of the other end of the buckle 8. A locking platform 12 is integrally formed on the side wall of the lever 9, and the locking platform 12 is engaged in the slot 11.

[0031] It is worth noting that both the buckle 8 and the lever 9 are flexible and can deform within a certain range.

[0032] When the connecting piece 2 needs to be installed on the side wall of the housing 1, first hook the hook space 6 onto the edge of the housing 1, and at the same time hook it, fasten the buckle 8 into the slot 11. Then, use the lever 9 to drive the locking platform 12 into the slot 11. At this time, the connecting piece 2 is fixed to the side wall of the housing 1. Similarly, when the connecting piece 2 needs to be removed, first drive the lever 9 away from the housing 1. The lever 9 drives the locking platform 12 to swing away from the housing 1, and the locking platform 12 disengages from the slot 11. Then, sequentially disengage the buckle 8 from the slot 11 and the hook space 6 from the edge of the housing 1 to complete the removal of the connecting piece 2.

[0033] For details, see Figure 4 The hinge mechanism includes a hinge shaft 13, and a hinge groove 14 is provided at the other end of the connecting piece 2. A hinge ear 15 is fixedly connected to one side of the support tray 7 at the position corresponding to the hinge groove 14. The hinge ear 15 is rotatably installed in the hinge groove 14. The hinge shaft 13 passes through the other end of the connecting piece 2 and the hinge ear 15 in sequence, and the hinge ear 15 is slidably sleeved on the side wall of the hinge shaft 13.

[0034] In addition, to facilitate the vertical fixation of the support tray 7 to the connecting piece 2, the connecting piece 2 is also equipped with a fixing component, which includes a spring 16. A fixing block 17 is fixedly connected to the inner corner of the hinge groove 14, and a fixing groove 18 is opened on the side wall of the hinge ear 15, with the fixing block 17 inserted into the fixing groove 18. The spring 16 is sleeved on the hinge seat, with one end of the spring 16 abutting against the groove wall of the hinge groove 14 and the other end of the spring 16 abutting against the inner wall of the hinge ear 15.

[0035] In its initial state, the pallet 7 is folded together with the connecting piece 2 via the hinge shaft 13 for easy carrying. When the pallet 7 needs to be unfolded and used, it is first swung away from the connecting piece 2. The pallet 7 causes the hinge ear 15 to rotate around the hinge shaft 13. When the fixing block 17 aligns with the fixing groove 18, the spring 16 releases its elastic force, causing the hinge ear 15 to move closer to the fixing block 17. At this time, the fixing block 17 is inserted into the fixing groove 18. Under the pressing action of the spring 16 and the limiting action of the fixing block 17, the pallet 7 and the connecting piece 2 are perpendicular to each other, and the pallet 7 is fixed to one side of the connecting piece 2. Similarly, when it is necessary to reset the folded support tray 7, first move the support tray 7 away from the fixing block 17. The support tray 7 drives the hinge ear 15 to move away from the fixing block 17. At this time, the fixing block 17 is disengaged from the fixing groove 18, and the hinge ear 15 compresses the spring 16. The spring 16 is elastically deformed. Then swing the support tray 7 towards the connecting piece 2 until the support tray 7 and the connecting piece 2 are completely folded.

[0036] See Figures 5-7 To facilitate the collection of cutting waste and tools, a transmission seat 19 is fixedly connected to the outer wall of the connecting piece 2. A material bag 20 is attached to the outer side of the connecting piece 2, and the material bag 20 is extensible. Frame rods 21 are fixedly installed at both ends of the material bag 20.

[0037] To facilitate the extension and swinging of the frame rod 21, a swinging mechanism is installed on the transmission base 19. This mechanism includes a telescopic rod 22 and a swing arm 23. The telescopic rod 22 has a fixed end and a telescopic end. The transmission base 19 has a U-shaped cross-section. The fixed end of the telescopic rod 22 is hinged to the inner bottom end of the transmission base 19, and the frame rod 21 is fixedly connected to the outer wall of the fixed portion of the telescopic rod 22. A first gear 24 is rotatably mounted on the inner top wall of the transmission base 19. One end of the swing arm 23 is fixedly connected to the first gear 24, and the other end of the swing arm 23 is hinged to the telescopic end of the telescopic rod 22.

[0038] Meanwhile, the transmission base 19 is also equipped with a transmission assembly, which includes a second gear 25 and an arc tooth 26. The arc tooth 26 is a partial gear and is fixedly connected to the outer wall of the hinge ear 15. The second gear 25 is rotatably mounted in the transmission base 19 and is located between the first gear 24 and the arc tooth 26. The first gear 24 and the second gear 25 mesh with each other, and the second gear 25 meshes with the arc tooth 26.

[0039] When the tray 7 unfolds away from the connecting piece 2, the tray 7 drives the hinge ear 15 to rotate, which in turn drives the arc tooth 26 to rotate. The arc tooth 26 drives the second gear 25 to rotate, which in turn drives the first gear 24 to rotate. The first gear 24 drives the swing rod 23 to swing outward, which in turn causes the telescopic rod 22 to extend and swing outward simultaneously. The telescopic rod 22 then drives the frame rod 21 to swing outward, which in turn unfolds the material bag 20. It is worth mentioning that the arc tooth 26 always remains engaged with the second gear 25. When the tray 7 returns to its original position and folds, the arc tooth 26 drives the second gear 25 to return to its original position and rotate. The second gear 25 drives the first gear 24 to return to its original position and rotate. The first gear 24 drives the swing rod 23 to swing inward, which in turn causes the telescopic rod 22 to shorten and swing inward simultaneously. The telescopic rod 22 then drives the frame rod 21 to swing inward, which in turn closes the material bag 20, thus achieving the joint unfolding and folding of the tray 7 and the material bag 20.

[0040] It should be noted that, see Figure 4 The other end of the connecting piece 2 is provided with a relief groove 27, and the arc tooth 26 is inserted into the relief groove 27.

[0041] The clearance groove 27 ensures that the arc tooth 26 has enough space to rotate, ultimately improving the stability of the material bag 20 when it opens or closes.

[0042] See Figure 6 To ensure that the pallet 7 can be fully folded, a receiving groove 28 is provided on the bottom surface of the pallet 7, and the material bag 20 and the transmission seat 19 are all received in the receiving groove 28.

[0043] When the tray 7 is unlocked and folded, the material bag 20 and the transmission seat 19 are both housed in the receiving slot 28, which helps to improve the ability of the tray 7 to be fully folded, reduce space occupation, and improve carrying convenience.

[0044] The working principle of a foldable fiber optic cleaver tray: The core purpose of a fiber optic fusion splicer is to achieve high-precision splicing of optical fibers. Before splicing the optical fibers, a fiber optic cleaver is used to cut a quartz glass optical fiber as thin as a hair to ensure that the cut end of the optical fiber is flat and smooth.

[0045] Therefore, when using a fiber optic cleaver in conjunction with a fiber optic fusion splicer, the tray needs to be installed on one side of the housing 1. At this time, the hook space 6 is first hooked onto the edge of the housing 1, and at the same time, the buckle 8 is fastened into the card slot 11. Then, the card platform 12 is driven to be fastened into the card slot 11 by the lever 9. At this time, the connecting piece 2 is fixed to the side wall of the housing 1.

[0046] When the support tray 7 needs to be unfolded and used, it is first swung away from the connecting piece 2. The support tray 7 causes the hinge ear 15 to rotate around the hinge shaft 13. When the fixing block 17 is aligned with the fixing groove 18, the spring 16 releases its elastic force and moves the hinge ear 15 closer to the fixing block 17. At this time, the fixing block 17 is inserted into the fixing groove 18. Under the pressing action of the spring 16 and the limiting action of the fixing block 17, the support tray 7 and the connecting piece 2 are perpendicular to each other, and the support tray 7 is fixed to one side of the connecting piece 2.

[0047] It is worth noting that when the support tray 7 unfolds away from the connecting piece 2, the support tray 7 drives the hinge ear 15 to rotate, the hinge ear 15 drives the arc tooth 26 to rotate, the arc tooth 26 drives the second gear 25 to rotate, the second gear 25 drives the first gear 24 to rotate, and the first gear 24 drives the swing rod 23 to swing outward. The swing rod 23 then drives the telescopic rod 22 to extend and swing outward simultaneously. The telescopic rod 22 then drives the frame rod 21 to swing outward, and the frame rod 21 then unfolds the material bag 20. At this time, cutting waste or tools can be loaded into the material bag 20.

[0048] In summary, the fiber optic cleaver is placed on the support tray 7 for use with the fiber optic fusion splicer. The support tray 7 supports the fiber optic cleaver, thereby improving the ease of use of the fiber optic cleaver.

[0049] 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.
