Description

Technical Field

[0001] The utility model belongs to the technical field of optical cable auxiliary splicing equipment, in particular to a foldable optical cable splicing box and a splicing table. Background Art

[0002] Optical cable splicing is the whole process of connecting the end of one optical cable to the beginning of the next optical cable to form a continuous optical cable line. As most optical cable splicing sites are outdoors, if there is a lot of wind and sand, it is easy to cause a lot of sand on the surface of the stripped optical fiber and inside the fusion splicer, resulting in large optical cable losses, which may cause the optical cable to need to be re-spliced, so it is impossible to ensure that the splicing operation is completed with high quality within the specified time.

[0003] The Chinese patent with the announcement number CN215953921U discloses a cold-proof and dust-proof optical cable splicing box. The sealed structural design effectively isolates the external dust and cold air, avoiding secondary operations caused by dust on the optical fiber surface and the inside of the fusion splicer during the splicing process.

[0004] In view of the above technical solution, the applicant believes that since there is an operating space for connecting optical cables in the splicing box, the volume of the operating space is fixed, which will occupy a larger position when the splicing box is moved or stored, resulting in low space utilization. Therefore, it is necessary to propose a foldable optical cable splicing box and splicing table to solve the above problems. Summary of the invention

[0005] In order to solve the above technical problems, the utility model provides a foldable optical cable splicing box and a splicing table to solve the problem in the prior art that the volume of the operating space in the splicing box is fixed, which will occupy a large position during the movement or storage of the splicing box, resulting in low space utilization.

[0006] In a first aspect, the present application provides a foldable optical cable auxiliary splicing box, comprising:

[0007] The frame includes a pair of first plates and a pair of second plates, wherein the first plates are staggered and connected to form a frame structure; the second plates include an axle and two third plates connected to the axle, and the third plates can rotate around the axle; the two second plates are folded or unfolded due to the axle moving toward the inside or outside of the frame, and the two first plates are folded or unfolded due to the folding or unfolding of the second plates as they move closer to or farther away from each other;

[0008] A cover plate, foldably connected to the top of the frame;

[0009] A connecting piece is connected to the shaft rod, and is used to be installed on the connection table when the two third plates of the second plate body form a preset angle.

[0010] Furthermore, a heater is installed inside the frame.

[0011] Furthermore, a lighting lamp is installed inside the frame.

[0012] Furthermore, the frame is provided with an operation hole for the arm to extend into the frame and an optical fiber hole for the optical cable to pass through the frame.

[0013] Furthermore, the connecting member is a rod structure, the connecting member is rotatably connected in the shaft, the upper and lower ends of the connecting member extend to the top and bottom of the shaft respectively, and the end of the connecting member located below the shaft has a thread.

[0014] Furthermore, the preset angle is 180 degrees.

[0015] Furthermore, the cover plate includes a pair of slide rails, and a fourth plate body is slidably connected between the pair of slide rails. The fourth plate body can seal the top of the frame body when it slides to a preset position.

[0016] Furthermore, the fourth plate body is an acrylic plate.

[0017] Furthermore, a sealing ring and a blocking curtain are respectively provided in the optical fiber hole and the operation hole.

[0018] An optical cable auxiliary splicing table is used in conjunction with the foldable optical cable auxiliary splicing box of the first aspect. The top of the splicing table is provided with screw holes, and the splicing box is installed on the splicing table because a connector is connected inside the screw holes.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] 1. Since the frame and the cover can be folded, the problem of the fixed volume of the operating space in the junction box is effectively solved, thereby reducing the volume of the junction box and improving space utilization, so that the junction box can be carried or stored, and the folding operation is simple and convenient.

[0021] 2. Since the connector is installed on the splicing table when the two third plates of the second plate form an angle of 180 degrees, not only can the splicing box be installed on the splicing table, but also the shape of the splicing box can be fixed. At this time, the frame is a four-frame structure with the largest internal space, which is beneficial for operators to perform optical cable splicing. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The present application aims to propose a foldable optical cable splicing box that can effectively isolate external dust and cold air while being convenient to fold and store.

[0034] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0035] Embodiment 1:

[0036] As attached Figure 1 To Attachment Figure 6As shown: The utility model provides a foldable optical cable auxiliary connection box, including a frame body 2, a cover plate 3 and a connector 4.

[0037] A heater 25 and a lighting lamp 26 are installed inside the frame 2. The heater 25 can be installed in the middle of the rear wall of the frame 2. The number of lighting lamps 26 can be set to two. The power plug voltage frequency of the heater 25 and the lighting lamp 26 is preferably 220v, 50-60HZ.

[0038] The frame 2 includes a pair of first plates 21 and a pair of second plates 22 . The first plates 21 and the second plates 22 are staggered and connected to form a frame structure.

[0039] In this embodiment, the first plate 21 and the second plate 22 can be connected by a hinge, the heights of all the first plate 21 and the second plate 22 are equal, and the length of the top of a single second plate 22 is less than half the length of the top of the first plate 21.

[0040] The second plate body 22 includes an axis rod 222 and two third plate bodies 221 connected to the axis rod 222, and the third plate bodies 221 can rotate around the axis rod 222; the two second plate bodies 22 are folded or unfolded due to the movement of the axis rod 222 toward the inside or outside of the frame body 2, and the two first plate bodies 21 are folded or unfolded as the second plate bodies 22 are folded or unfolded and move closer to or away from each other, thereby reducing the operating space inside the frame body 2, thereby reducing the volume of the junction box for carrying or storage.

[0041] In this embodiment, one end of the third plate 221 can be directly sleeved on the outer surface of the shaft 222. The two third plates 221 of a single second plate 22 can rotate around the shaft 222 to form a variable angle. When the two shafts 222 move toward the inside or outside of the frame 2, the corresponding angle decreases or increases within the range of 0-180 degrees, and the folding range of the single second plate 22 increases as the angle decreases. The two first plates 21 will be folded or unfolded accordingly due to the folding or unfolding of the second plate 22.

[0042] The frame 2 is provided with an operation hole 23 for the arm to extend into the frame 2 and an optical fiber hole 24 for the optical cable to pass through the frame 2, and a sealing ring 231 and a blocking curtain 241 are respectively provided in the optical fiber hole 24 and the operation hole 23. After the frame 2 is unfolded, the optical cable enters the frame 2 from the optical fiber hole 24, and the operator's arm extends into the frame 2 from the sealing ring 231 of the operation hole 23 to perform the splicing operation. The sealing ring 231 and the blocking curtain 241 can both play the role of filling the gap, thereby ensuring the sealing performance of the splicing box.

[0043] The cover plate 3 can be folded and connected to the top of the frame 2. Specifically, the cover plate 3 may include a pair of slide rails 31, and a fourth plate 32 is slidably connected between the pair of slide rails 31. The fourth plate 32 can be slid to a preset position to seal the top of the frame 2. A sealing strip can be provided on the top of the frame 2 so that the cover plate 3 can fill the gap between the frame 2 and the cover plate 3 when it is turned over to be attached to the upper surface of the frame 2, thereby achieving a good sealing effect. Among them, the fourth plate 32 is preferably a transparent acrylic plate, so that the operator can better observe the internal situation of the frame 2.

[0044] The connector 4 is connected to the shaft 222, and is used to be installed on the splicing table 1 when the two third plates 221 of the second plate 22 form a preset angle. After the connector 4 is installed on the splicing table 1, the second plate 22 can no longer be adjusted, and the shape of the frame 2 is fixed. The preset angle is 180 degrees, and the frame 2 is a four-frame structure at this time, with the largest internal space, which is conducive to the operator to perform the splicing of the optical cable operation.

[0045] Specifically, the connecting member 4 is a rod body structure, and the connecting member 4 is rotatably connected in the shaft 222. The upper and lower ends of the connecting member 4 extend to the top and bottom of the shaft 222 respectively. The end of the connecting member 4 located below the shaft 222 has a thread, and the connecting member 4 can be installed on the connection table 1 by means of a threaded connection.

[0048] The top of the splicing table 1 is provided with a screw hole 11, and the screw hole 11 is connected inside thereof so that the splicing box is installed on the splicing table 1. The splicing box is stably and firmly installed on the splicing table 1, and the assembly operation of the splicing box and the splicing table 1 is also simple and convenient.

[0049] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
