Description

Technical Field

[0001] The invention relates to the technical field of optical cable terminal boxes, and in particular to an outdoor optical cable terminal box equipped with a protective structure. Background Art

[0002] In today's digital age, the stable operation of communication networks is crucial. As a key node device in optical fiber communication networks, outdoor optical cable terminal boxes are widely used in various outdoor scenarios, and undertake the important tasks of connecting, distributing and protecting optical cables. However, the outdoor environment is complex and changeable, and faces many severe challenges, especially the threat from various unexpected impacts.

[0003] With the continuous development of urban construction and transportation infrastructure, the number of vehicles on the road is increasing, and the driving speed is also increasing. Outdoor optical cable terminal boxes are often installed in areas along traffic routes such as roadsides, bridges, and tunnels, and are inevitably exposed to the risk of vehicle collisions. Once hit by a vehicle, the terminal box with a traditional structure is difficult to withstand the huge impact force, which is very likely to cause the shell to break, the internal optical fiber fusion parts to break, and the connection parts to loosen or be damaged, which will cause communication interruption, bringing serious impacts to people's lives, work, and the normal operation of society.

[0004] Existing outdoor optical cable terminal boxes often lack protection against such impacts. Although the outer shells of most terminal boxes have a certain strength, they still cannot effectively protect the key internal components when subjected to high-intensity impacts such as vehicle collisions. In order to reduce costs, some terminal boxes use materials with low strength and hardness, or do not fully consider impact resistance in the design, which makes them very easy to be damaged when subjected to accidental impacts. Some terminal boxes with preliminary impact resistance designs may only provide a certain degree of protection against a certain type of impact, and cannot fully cope with a variety of impact scenarios of different types and intensities.

[0005] Therefore, it is necessary to design an outdoor optical cable terminal box equipped with a protective structure to solve the above technical problems. Summary of the invention

DETAILED DESCRIPTION

[0039] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] Embodiment: An outdoor optical cable terminal box equipped with a protective structure, such as Figure 1-Figure 19 As shown, it includes a bottom plate 1, a connecting rail 2, a rocker arm 3, a connecting ring 4, a back plate 5, a box body 6, an anti-collision beam 101, a protection frame 7, a side plate 8, a protection door 9, a protection plate 10, a front buffer assembly and a side protection assembly. Two connecting rails 2 are installed on the rear side of the bottom plate 1 by bolts. The connecting rails 2 are fixedly connected to the building by expansion bolts. The upper part of the front side of the bottom plate 1 is rotatably connected to the rocker arm 3, and the lower part of the rocker arm 3 is fixedly connected to the connecting ring 4. The front side of the connecting ring 4 is fixedly connected to the back plate 5 by bolts. The front side of the back plate 5 is fixed by bolts. A box body 6 is connected, and a plurality of anti-collision beams 101 are fixedly connected to the four side surfaces of the box body 6. A protection frame 7 is slidably connected to the front side of the box body 6. The left and right sides of the protection frame 7 are fixedly connected to side panels 8 by bolts. Both side panels 8 are slidably connected to the box body 6. A protection door 9 is rotatably connected to the front side of the protection frame 7. A protection plate 10 is fixedly connected to the middle of the front side of the protection door 9. The protection plate 10 is made of plastic material. A front buffer component for buffering the front impact force is provided between the box body 6 and the protection frame 7, and a side protection component for protecting the side is provided on the side of the box body 6.

[0041] like Figure 7-10As shown, the front buffer assembly includes a sleeve 1101, a telescopic rod 1102, a return spring 1103 and a connecting block 1104. Three longitudinally arranged sleeves 1101 are fixedly connected on both sides of the box body 6 by bolts. The inside of each sleeve 1101 is slidably connected with a telescopic rod 1102. A return spring 1103 is fixedly connected between each telescopic rod 1102 and the sleeve 1101. Each telescopic rod 1102 is in sealed contact with the sleeve 1101, and there is a large friction force. A connecting block 1104 is welded on the front side of each telescopic rod 1102, and the three connecting blocks 1104 on the same side are fixedly connected to the side plate 8 on the same side by bolts.

[0042] like Figure 11-Figure 15 As shown, the side protection assembly includes a mounting frame 1201, a storage airbag 1202, a connecting pipe 1203, a three-way pipe 1204, an air delivery pipe 1205, a protection airbag 1206 and a connecting pipe 2 1207. The upper front part of the back plate 5 is fixedly connected to the mounting frame 1201 by bolts, and the storage airbag 1202 is fixedly connected inside the mounting frame 1201. A large amount of compressed gas is stored inside the storage airbag 1202. The bottom of the storage airbag 1202 is fixedly connected to the storage airbag 1202. It is also connected with a connecting pipe 1203, the bottom of the connecting pipe 1203 is connected with a three-way pipe 1204, the left and right openings of the three-way pipe 1204 are fixedly connected and connected with an air supply pipe 1205, the front and rear sides of the outer side of the box body 6 are fixedly connected with protective airbags 1206, the other ends of the two air supply pipes 1205 are fixedly connected and connected with the rear protective airbag 1206, and the front and rear protective airbags 1206 are fixedly connected and connected with a connecting pipe 2 1207.

[0043] like Fig.12 , Fig.13 , Fig.14 and Fig.16 As shown, it also includes a block 1301, a connecting rod 1302, a return spring 1303 and a block 1304. The block 1301 is slidably connected inside the three-way pipe 1204, and a connecting rod 1302 is welded to the front side of the block 1301. The other end of the connecting rod 1302 is located behind the protective door 9. A return spring 1303 is fixedly connected between the block 1301 and the connecting ring 4. The return spring 1303 is sleeved on the outside of the block 1301. A block 1304 is fixedly installed in the middle of the front side of the base plate 1. The rear side of the block 1301 abuts against the front side of the block 1304. The block 1304 is made of elastic plastic material, and long holes 1305 are opened on both sides of the front side of the base plate 1.

[0044] When the terminal box needs to be installed in areas along traffic routes such as roadsides, bridges and tunnels, the connecting rails 2 can be first fixedly installed on the building wall by expansion bolts, and then the base plate 1 can be fixedly installed between the two connecting rails 2 by fixing bolts. In this way, the terminal box can be fixedly installed, and then the protective door 9 can be opened, and then the optical cable can be fixedly installed inside the box body 6, and then the protective door 9 can be closed and locked. In this way, the important tasks of connecting, distributing and protecting the optical cable can be achieved.

[0045] If the side of the installed terminal box is hit by a vehicle on the roadside, and the vehicle hits the side of the box body 6, the box body 6 will drive the back plate 5, the connecting ring 4 and the rocker arm 3 to swing on the bottom plate 1, and the anti-collision beam 101 will provide a stronger supporting force for the box body 6 when the box body 6 is hit. Initially, the return spring 1303 is in a compressed state. When the back plate 5 swings on the bottom plate 1, the back plate 5 will drive the mounting frame 1201, the storage airbag 1202, the connecting pipe 1203 and the three-way pipe 1204 to swing synchronously. When the three-way pipe 1204 swings, it will drive the block 1301 to swing. When the block 1301 swings, it will break away from the abutment state with the block 1304, and then the block 1301 Under the reset action of the return spring 1303, it will slide backward into the long strip hole 1305, so that the block 1301 will open the three openings of the three-way pipe 1204, and the large amount of compressed gas stored in the storage airbag 1202 will be transported to the two air pipes 1205 through the three-way pipe 1204, and then the protective airbag 1206 on the rear side will be inflated, and the protective airbag 1206 on the front side will be inflated under the action of the connecting pipe 1207. After the two protective airbags 1206 are inflated, the side of the box body 6 can be fully protected to prevent the impact force of the vehicle from entering the interior of the box body 6, reduce the impact on the optical cable inside the box body 6, and improve the protection effect of the box body 6.

[0046] If the front side of the installed terminal box is hit by a vehicle on the roadside, the vehicle hits the front side of the protective frame 7, and the protective frame 7 is hit and the side plate 8 moves backward along the box body 6, so that the side plate 8 will drive the telescopic rod 1102 to slide inside the sleeve 1101. At this time, multiple return springs 1103 are compressed at the same time, and the telescopic rod 1102 and the sleeve 1101 are in sealed contact, and there is a large friction force, which greatly offsets the impact force on the protective frame 7 and protects the box body 6 and the optical cable inside the protective frame 7. If the protective frame 7 and the protective door 9 are hit hard and slide backward a long distance When moving, since the block 1304 is made of elastic plastic material, the protective door 9 will squeeze the connecting rod 1302 to slide backward, so that the connecting rod 1302 drives the block 1301 to slide backward synchronously, so that the block 1301 will also open the three openings of the three-way pipe 1204, and then the effect is consistent with that when the side of the terminal box is hit by a vehicle as described above, the storage airbag 1202 will inflate the protective airbag 1206 through the three-way pipe 1204, so that when the front side of the terminal box is hit hard, the side of the terminal box will also be protected synchronously, thereby achieving an all-round protection effect on the terminal box.

[0047] like Fig.17 As shown, it also includes a mounting seat 1401, a protective frame 1402 and a clamping block 1404. The mounting seats 1401 are fixedly installed on both sides of the upper front side of the base plate 1 by means of bolts. The protective frame 1402 is rotatably connected between the two mounting seats 1401. The protective frame 1402 protects the box body 6 and the protective frame 7. A plurality of through holes 1403 for the protective frame 1402 to pass through are opened on both sides of the front side of the base plate 1. After the protective frame 1402 passes through the through holes 1403, it rests on the building. Clamping blocks 1404 are fixedly installed on both sides of the upper front side of the base plate 1. The clamping blocks 1404 are located above the mounting seats 1401 on the same side. The clamping blocks 1404 are made of plastic material. The protective frame 1402 rotates upward to be clamped on the clamping blocks 1404.

[0048] When the terminal box needs to be installed, the protective frame 1402 can be first rotated upward along the mounting seat 1401, and the protective frame 1402 can be stuck on the two blocks 1404, and then the terminal box can be installed and the optical cable can be connected to the inside of the box body 6. After the optical cable is connected and the protective door 9 is locked, the protective frame 1402 can be rotated downward to make the protective frame 1402 disengage from the block 1404, and then the protective frame 1402 is passed through the through hole 1403 and pressed against the building connected to the connecting slide rail 2, so that the protective frame 1402 can surround the box body 6 and the protective frame 7, thereby improving the safety of the optical cable.

[0049] like Figure 17-Figure 19As shown, it also includes an airbag 1501, a push switch 1502 and a push rod 1503. The airbag 1501 is fixedly installed inside the protective door 9, and the push switch 1502 is fixedly installed at the front center of the airbag 1501. The push switch 1502 controls the opening of the airbag 1501. The pressing rod 1503 is fixedly connected to the middle of the protective frame 1402. When the protective frame 1402 protects the box body 6 and the protective frame 7, the pressing rod 1503 is located directly in front of the push switch 1502.

[0050] When the protective frame 1402 surrounds the box body 6 and the protective frame 7 to protect the optical cable, the protective frame 1402 will drive the pressing rod 1503 to press against the front side of the protective plate 10. If the front side of the protective frame 7 is hit by a vehicle, the protective frame 1402 provides a first layer of protection. If the protective frame 1402 is deformed by the impact, the pressing rod 1503 will move backward to squeeze the protective plate 10. The protective plate 10 is made of plastic material and is easily cracked by impact. After the pressing rod 1503 breaks the protective plate 10, it will press the pressing switch 1502. The pressing switch 1502 will control the airbag 1501 to open, so that the airbag 1501 is quickly inflated. In this way, under the protection of the inflated airbag 1501, a second layer of protection can be provided for the optical cable inside the box body 6, thereby further improving the safety of the optical cable.

[0051] like Figure 1 As shown, a protective plate 16 is also included. The upper front part of the base plate 1 is fixedly connected with the protective plate 16 by means of bolts. The protective plate 16 is located directly above the box body 6 and the protective frame 7. The protective plate 16 can provide top protection for the box body 6 and the protective frame 7 to prevent the terminal box from being damaged by falling rocks when it is installed on the edge of a mountain.

[0052] like Figure 1 As shown, it also includes an anti-collision rubber strip 17. The edges of the front side of the protection frame 7 are all pasted with the anti-collision rubber strip 17, so as to improve the impact resistance of the protection frame 7 and enhance the safety of the terminal box.

[0053] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
