Description

Technical Field

[0001] This invention relates to the field of optical cable splice box technology, specifically to an anti-seismic bracket for an optical cable splice box and its usage method. Background Technology

[0002] As an indispensable basic device in optical fiber communication networks, fiber optic splice closures play an important role in protecting fiber optic splices and distributing optical signals. Among them, cap-type fiber optic splice closures are widely used in outdoor communication networks due to their compact structure, good sealing performance, and convenient operation. They are usually installed in manholes or handholes, or directly erected on utility poles or towers. In actual application environments, especially in earthquake-prone areas or in situations with other severe vibration and impact risks, the seismic performance of fiber optic splice closures is crucial.

[0003] Chinese Patent Application No. 202022784071.9 discloses an arc-shaped fixing bracket for communication optical cable splice boxes, including a base plate frame. At least one connecting component is provided on the base plate frame. The connecting component includes a connector and two vertical arc-shaped supports symmetrically arranged and fixed to the connector. The tops of the two vertical arc-shaped supports are detachably connected, and the connector is connected to the upper side of the base plate frame. However, during use, vibration of the splice box can cause tension between the incoming / outgoing lines and the main body of the splice box, affecting the stability of the internal optical fiber splice points.

[0004] In addition, the destructive force of disasters such as earthquakes is not unidirectional. The complex multidimensional impacts they generate pose a serious threat to the junction boxes fixed on the brackets. In the existing technology, the brackets used to fix the cap-type optical cable junction boxes are mostly rigid structures or only provide simple vertical and horizontal buffers, which are difficult to resist impacts from multiple angles, making the junction boxes easy to be damaged in the multidimensional impact environment. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide an anti-vibration bracket for optical cable junction boxes and its usage method. When the junction box body is subjected to impact vibration, it prevents the incoming and outgoing lines from being pulled between the junction box and the junction box, and can effectively resist impact vibration from multiple angles, ensuring the reliability and stability of the junction box in complex environments. It can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an anti-vibration bracket for an optical cable junction box, comprising a buffer assembly, a side impact-resistant assembly on the side of the buffer assembly, a front impact-resistant assembly on the side of the side impact-resistant assembly, and a cable bundle assembly at the bottom of the buffer assembly;

[0007] The buffer assembly includes a fixed base, fixed plates on both sides of the fixed base, a guide rod slidingly passing through the side of the fixed plate, a slide seat at both ends of the guide rod, a guide post slidingly passing through the middle of the slide seat, and an end seat at both ends of the guide post.

[0008] The side impact-resistant component includes an arc-shaped rod, with a movable seat slidably sleeved in the middle of the arc-shaped rod, and side elastic plates are provided between the movable seat and the end seats on both sides.

[0009] Both sides of the side elastic sheet are provided with pressure plates, and the side of the pressure plates abuts against the side expansion bladder.

[0010] Preferably, both ends of the guide rod are fitted with transverse springs, which are located between the fixed plate and the slide block;

[0011] Vertical springs are fitted on both sides of the guide post, and the vertical springs are located between the end seat and the slide.

[0012] Preferably, two arc-shaped rods are provided vertically, and the arc-shaped rods are located between the end seats on both horizontal sides;

[0013] The side telescopic bladder is equipped with a side air tube, and the side telescopic bladder is mounted on the side of the fixed base via a side frame.

[0014] Preferably, the front impact-resistant assembly includes a slide rail disposed between the upper and lower movable seats. A limiting rod is vertically provided inside the slide rail. Guide seats are movably sleeved on both sides of the limiting rod. Support arms are hinged on the upper and lower guide seats. The two support arms are arranged in a ">" shape. A front elastic plate is provided between the upper and lower guide seats.

[0015] Preferably, both ends of the two support arms are hinged with clamps, each clamp having a built-in connector box. A front telescopic bladder is provided between the upper and lower clamps via a connecting plate. The front telescopic bladder is provided with a front air tube, and the end of the front telescopic bladder abuts against the side of the front elastic sheet.

[0016] Preferably, the wire harness assembly includes a ring seat, which is mounted on the bottom of the fixing seat via a base frame. The ring seat corresponds to the clamp position, and a hose clamp is provided inside the ring seat.

[0017] Preferably, the hose clamp is provided with sliding rods on both sides and the front side, and the side of the ring seat is provided with a movable groove corresponding to the sliding rod. A mounting seat is slidably connected inside the movable groove, and a return spring is provided between the two sides of the mounting seat and the two sides of the movable groove, respectively.

[0018] Preferably, a cylindrical seat is provided through the side of the mounting base, the cylindrical seat is movably sleeved on the slide rod, a connecting spring is provided between the inner end face of the cylindrical seat and the slide rod, an air nozzle is provided at the outer end of the cylindrical seat, the air nozzles located on both sides of the ring seat are cross-connected with the side air pipes on both sides, and the air nozzle located on the front side of the ring seat is connected with the front air pipe.

[0019] This invention also discloses a method for using an anti-seismic bracket for an optical cable junction box, comprising the following steps:

[0020] S1. Install the fixing seat in the buffer assembly into the preset position through the fixing slots on both sides, tighten the clamps on the upper and lower sides of the optical cable junction box, pass the inlet and outlet lines of the junction box through the clamps, and use tools to gradually tighten the clamps to fix the inlet and outlet lines.

[0021] S2. When the junction box is subjected to a horizontal impact, the impact force is transmitted to the slide through the front anti-impact component and the side anti-impact component. The slide moves along the guide rod in the impact direction and compresses the transverse spring on the corresponding side. The transverse spring absorbs the impact energy through elastic deformation, thus achieving horizontal buffering.

[0022] S3. When the junction box is subjected to a vertical impact, the impact force is transmitted to the guide post through the front anti-impact component and the side anti-impact component. The guide post moves vertically along the slide and compresses the vertical spring on the corresponding side. The vertical spring absorbs the impact energy through elastic deformation, thus achieving vertical buffering.

[0023] S4. When the junction box is subjected to a frontal oblique impact, the front anti-impact component drives the movable seat to slide along the arc-shaped rod, squeezing the corresponding side elastic sheet. The side elastic sheet deforms and absorbs energy. At the same time, the side elastic sheet squeezes the side telescopic bladder through the pressure plate, and the side telescopic bladder deforms to achieve secondary buffering.

[0024] S5. When the junction box is impacted from the front, the clamp presses the support arm, which drives the guide seat to close along the limit rod, squeezing the front elastic plate. The front elastic plate deforms and absorbs energy. At the same time, the front elastic plate squeezes the front telescopic bladder, and the deformation of the front telescopic bladder achieves secondary buffering.

[0025] S6. When the side and front telescopic bladders are compressed to generate airflow, the airflow enters the corresponding nozzle, flows into the cylinder seat, pushes the slide rod to extend, and drives the hose clamp to move in the direction of the junction box, so that the inlet and outlet lines are moved synchronously. After the impact disappears, the reset spring pushes the mounting seat to reset, and drives the hose clamp back to the initial position.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. When the junction box is subjected to a horizontal impact, the impact force drives the slide to slide along the guide rod, compressing the transverse spring and absorbing the horizontal impact energy. When subjected to a vertical impact, the guide post slides along the slide, compressing the vertical spring to achieve vertical buffering. When subjected to a forward oblique impact, the movable seat slides along the arc-shaped rod, squeezing the side elastic plate to produce elastic deformation and resist the oblique impact. When subjected to a direct frontal impact, the support arm moves to drive the guide seat to close, squeezing the front elastic plate to deform and absorb the frontal impact energy. This multi-dimensional impact-resistant design significantly improves the stability and reliability of the junction box in complex vibration environments.

[0028] 2. This invention introduces a two-stage buffering mechanism. When the side elastic sheet undergoes significant deformation due to an oblique impact, the pressure plate compresses the side telescopic bladder, utilizing the elastic deformation of the side telescopic bladder to provide additional buffering. When the front elastic sheet undergoes significant deformation due to a frontal impact, the front telescopic bladder is directly compressed, absorbing more impact energy through the deformation of the front telescopic bladder. This two-stage buffering structure effectively prevents the elastic sheet from exceeding its deformation limit under severe impact, ensuring the long-lasting protection and buffering effect of the support under high-intensity vibration.

[0029] 3. When the junction box is impacted, the side or front telescopic bladder of this invention compresses to generate airflow. The airflow enters the air nozzle on the ring seat through the side or front air pipe, pushing the slide rod inside the cylinder seat to extend and driving the hose clamp to move in the direction of the junction box's movement. This causes the inlet and outlet cables to move synchronously with the junction box, avoiding tension and pulling on the internal connection points of the inlet and outlet cables due to the junction box moving alone, thus ensuring the stability of the inlet and outlet cable connection points.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1

[0038] Please see Figure 1-5 This embodiment provides a shock-resistant bracket for an optical cable junction box, including a buffer assembly 1. The buffer assembly 1 is used to enable the junction box to resist impact vibrations in the vertical and horizontal directions. The buffer assembly 1 includes a fixed base 101, with fixed plates 102 on both sides of the fixed base 101. A guide rod 103 slides through the side of the fixed plate 102. Both ends of the guide rod 103 are provided with slide seats 104. Both ends of the guide rod 103 are fitted with transverse springs 105, which are located between the fixed plate 102 and the slide seats 104. A guide post 106 slides through the middle of the slide seat 104. Both ends of the guide post 106 are provided with end seats 107. Both sides of the guide post 106 are fitted with vertical springs 108, which are located between the end seats 107 and the slide seats 104.

[0039] Specifically, the fixing base 101 is used for overall installation and fixing. Fixing grooves for fixing are opened on both sides of the fixing base 101. When the connector box is subjected to horizontal impact vibration on one side, the front anti-impact component 3 and the side anti-impact component 2 drive the slide 104 to move horizontally to one side. The horizontal spring 105 on one side is compressed and buffers the connector box. When the connector box is subjected to vertical impact vibration, the front anti-impact component 3 and the side anti-impact component 2 drive the guide post 106 to slide along the slide 104. The vertical spring 108 on one side is compressed and buffers the connector box in the vertical direction.

[0040] The side of the buffer assembly 1 is provided with a side impact-resistant assembly 2. The side impact-resistant assembly 2 is used to enable the junction box to resist impact vibration from the front tilt direction. The side impact-resistant assembly 2 includes an arc-shaped rod 201. Two arc-shaped rods 201 are provided vertically. The arc-shaped rods 201 are located between the end seats 107 on both horizontal sides. A movable seat 202 is slidably sleeved in the middle of the arc-shaped rod 201. A side elastic piece 203 is provided between the movable seat 202 and the end seats 107 on both sides.

[0041] Specifically, in the initial state, the movable seat 202 is located in the middle of the arc-shaped rod 201. When the connector box is subjected to an oblique impact vibration from the front, the connector box drives the movable seat 202 to slide along the arc direction of the arc-shaped rod 201 through the front anti-impact component 3, so that the side elastic plate 203 on one side is squeezed and produces an outward bulging elastic deformation, thereby enabling the connector box to resist the impact vibration from the front side.

[0042] The side of the side impact-resistant component 2 is provided with a front impact-resistant component 3. The front impact-resistant component 3 is used to enable the junction box to resist impact vibration from the front. The front impact-resistant component 3 includes a slide rail 301, which is located between the upper and lower movable seats 202. The slide rail 301 is vertically provided with a limiting rod 302 inside. Guide seats 303 are movably sleeved on both sides of the limiting rod 302. Support arms 304 are hinged on the upper and lower guide seats 303. The two support arms 304 are arranged in a ">" shape. A front elastic plate 305 is provided between the upper and lower guide seats 303. The ends of the two support arms 304 are hinged with clamps 4. The junction box is built into the clamps 4.

[0043] Specifically, both the side elastic plate 203 and the front elastic plate 305 are arc-shaped structures. The clamps 4 on the upper and lower sides are used to fasten the joint box to the upper and lower sides. When the joint box is subjected to impact vibration from the front, the joint box compresses the support arms 304 on both sides through the clamps 4, which increases the opening of the support arms 304 on both sides. At the same time, the opening of the end of the support arms 304 on both sides near the slide rail 301 decreases. The guide seats 303 on the upper and lower sides move in opposite directions and close together. The front elastic plate 305 generates an elastic deformation that bulges forward, thereby enabling the joint box to resist impact vibration from the front.

[0044] The bottom of the buffer assembly 1 is provided with a cable harness assembly 5. The cable harness assembly 5 is used to fix the inlet and outlet cables of the junction box. The cable harness assembly 5 includes a ring seat 502. The ring seat 502 is located at the bottom of the fixed seat 101 through the base frame 501. The ring seat 502 corresponds to the position of the clamp 4. The inside of the ring seat 502 is provided with a hose clamp 503.

[0045] Specifically, by passing the incoming and outgoing lines of the junction box through the hose clamp 503 and gradually tightening the hose clamp 503 using the toolbox, the incoming and outgoing lines of the junction box are fixed to prevent external forces such as wind from causing the incoming and outgoing lines to swing back and forth, thus affecting the stability of the connection point.

[0046] In use, the overall installation and fixation of the optical cable junction box anti-seismic bracket is based on the fixing seat 101 in the buffer assembly 1. The fixing seat 101 has fixing grooves on both sides. The bracket can be installed in a preset position on the utility pole, iron tower, or manhole or handhole through the fixing grooves. The clamps 4 on the upper and lower sides of the front impact-resistant assembly 3 are used to fasten the junction box to the upper and lower sides. The initial assembly of the junction box and the bracket is completed by the locking operation of the clamps 4, ensuring the reliability of the connection between the junction box and the bracket. In the cable bundle assembly 5, after the junction box is installed, the inlet and outlet wires of the junction box are passed through the hose clamp 503 inside the ring seat 502. Then, the hose clamp 503 is gradually tightened with tools. The clamping force of the hose clamp 503 reliably fixes the inlet and outlet wires of the junction box, avoiding the inlet and outlet wires from swinging back and forth due to external forces such as wind, thereby ensuring the stability of the connection between the inlet and outlet wires and the junction box and preventing the connection from loosening due to swinging.

[0047] When the junction box is subjected to horizontal impact vibration on one side, the impact force is transmitted to the slide 104 of the buffer assembly 1 through the front anti-impact component 3 and the side anti-impact component 2. This causes the slide 104 to move in the direction of impact along the guide rod 103 that slides through the side of the fixed plate 102. At this time, the transverse spring 105 located between the fixed plate 102 and the side slide 104 is compressed. The transverse spring 105 uses its own elastic deformation to generate a reverse buffer force, which offsets part of the horizontal impact energy, thereby resisting the horizontal impact vibration of the junction box. When the junction box is subjected to vertical impact vibration, the impact force is also transmitted to the guide post 106 through the front anti-impact component 3 and the side anti-impact component 2. This causes the guide post 106 to move vertically along the sliding hole in the middle of the slide 104. The vertical spring 108 located on the corresponding side between the end seat 107 and the slide 104 is compressed. The vertical spring 108 forms a vertical buffer with the help of elastic restoring force, further absorbing the vertical impact energy and preventing the junction box from being damaged by vertical impact.

[0048] When the junction box is subjected to an oblique impact vibration from the front, the junction box, through the front anti-impact component 3, drives the movable seat 202 in the side anti-impact component 2 to slide along the arc trajectory of the arc-shaped rod 201. During the sliding process, the movable seat 202 will compress the side elastic plate 203 on the corresponding side, causing the side elastic plate 203 to produce an outward convex elastic deformation. During the deformation process, the side elastic plate 203 absorbs the energy generated by the oblique impact from the front, thereby effectively buffering the oblique impact vibration from the front of the junction box. When the junction box is subjected to an impact vibration from directly in front, the junction box applies pressure to the support arms 304 on both sides through the fastened clamps 4. At the same time, the openings of the two arms 304 near the slide rail 301 decrease, which in turn drives the guide seats 303 on both sides to move in opposite directions and close along the limiting rods 302 vertically set inside the slide rail 301. The closing action of the guide seats 303 will squeeze the front elastic plate 305 located between the two, causing the front elastic plate 305 to produce an elastic deformation that bulges forward. The front elastic plate 305 absorbs the energy generated by the impact from the front through its own elastic deformation, thus resisting the impact vibration from the front of the junction box. Ultimately, this ensures the structural stability of the junction box under impact vibration environments in different directions, as well as the reliable connection of the internal optical fiber fusion splice.

[0049] However, when the junction box is subjected to significant impact vibration from directly in front or at an angle to the front, the front elastic plate 305 and the side elastic plate 203 may exceed their resistance limits when resisting the significant impact vibration through their own elastic deformation, making it difficult to cope with the significant impact vibration. Therefore, the following improvements are made:

[0050] Both sides of the side elastic sheet 203 are provided with pressure plate 204. The side of the pressure plate 204 abuts against the side telescopic bladder 206. The side telescopic bladder 206 is provided on the side of the fixed seat 101 through the side frame 205.

[0051] Specifically, when the side elastic plate 203 undergoes elastic deformation to buffer the impact vibration from the front of the junction box, the outward protrusion of the side elastic plate 203 will squeeze the side telescopic bladder 206 through the pressure plate 204.

[0052] A front telescopic bladder 307 is provided between the upper and lower clamps 4 via a connecting plate 306, and the end of the front telescopic bladder 307 abuts against the side of the front elastic sheet 305.

[0053] Specifically, when the front elastic plate 305 undergoes elastic deformation that bulges forward to buffer the impact vibration from the front of the junction box, it will compress the front telescopic bladder 307. Both the side telescopic bladder 206 and the front telescopic bladder 307 are made of elastic material.

[0054] In use, when the front elastic plate 305 undergoes elastic deformation due to impact and vibration of the junction box, it will compress the front telescopic bladder 307, causing the front telescopic bladder 307 to undergo elastic deformation. This elastic deformation of the front telescopic bladder 307 will achieve secondary buffering. When the side elastic plate 203 on one side undergoes elastic deformation due to impact and vibration of the junction box, it will compress the corresponding side telescopic bladder 206, causing the side telescopic bladder 206 to undergo elastic deformation. This elastic deformation of the side telescopic bladder 206 will achieve secondary buffering.

[0055] Example 2

[0056] In addition, when the junction box is subjected to impact and vibration, it will shift, while the incoming and outgoing cables are in a fixed and taut state. Therefore, the incoming and outgoing cables will pull on the wiring points inside the junction box, causing the wiring to loosen. Therefore, the following improvements are made:

[0057] The side retractable bladder 206 is equipped with a side trachea 207.

[0058] Specifically, the airflow generated after the side ventilator 206 is compressed is discharged through the side ventilator 207 and enters the air nozzle 510 on the side away from the side ventilator 207.

[0059] An anterior trachea 308 is provided on the anterior retractable bladder 307.

[0060] Specifically, the airflow generated by the compression of the front retractable bladder 307 enters the air nozzle 510 located at the front through the front trachea 308.

[0061] The hose clamp 503 is provided with slide rods 504 on both sides and the front side. The side of the ring seat 502 is provided with a movable groove 505 at the position corresponding to the slide rod 504. The movable groove 505 is slidably connected to the mounting seat 506. The two sides of the mounting seat 506 are respectively provided with return springs 507 between them and the two sides of the movable groove 505.

[0062] A cylindrical seat 508 is provided through the side of the mounting base 506. The cylindrical seat 508 is movably sleeved on the slide rod 504. A connecting spring 509 is provided between the inner end face of the cylindrical seat 508 and the slide rod 504. An air nozzle 510 is provided at the outer end of the cylindrical seat 508. The air nozzles 510 located on both sides of the ring seat 502 are cross-connected with the side air pipes 207 on both sides. The air nozzle 510 located on the front side of the ring seat 502 is connected to the front air pipe 308.

[0063] Specifically, in the initial state, the mounting base 506 is located in the middle of the movable groove 505. The airflow passes through the front air pipe 308 or the side air pipe 207 and enters the cylinder seat 508 through the air nozzle 510, thereby driving the slide rod 504 to extend, which in turn pushes the hose clamp 503 to move, thereby driving the inlet and outlet lines to move towards the side of the connector box, avoiding the connector box moving alone and pulling the inlet and outlet lines, which would cause the inlet and outlet line connection to loosen. At the same time, the hose clamp 503 drives the slide rod 504, cylinder seat 508 and mounting base 506 on other sides to slide along the movable groove 505.

[0064] When in use, when the junction box is subjected to impact vibration from the front or from the front at an angle, the front anti-impact component 3 and the side anti-impact component 2 will drive the front telescopic bladder 307 and the side telescopic bladder 206 to undergo elastic deformation, generating airflow.

[0065] When the junction box is subjected to an impact vibration from directly in front, the front elastic plate 305 undergoes an elastic deformation that bulges forward, squeezing the front telescopic bladder 307 and compressing it. The airflow generated by the compression of the front telescopic bladder 307 is discharged through the front air pipe 308 and enters the air nozzle 510 located on the front side of the ring seat 502.

[0066] When the junction box is subjected to an impact vibration from the front at an angle, the side elastic plate 203 on one side undergoes an outward elastic deformation, which compresses the corresponding side telescopic bladder 206 through the pressure plate 204, causing the side telescopic bladder 206 to compress. The airflow generated by the compression of the side telescopic bladder 206 is discharged through the side air pipe 207 and crosses into the air nozzle 510 located on the ring seat 502. That is, when the junction box is subjected to an impact vibration from the left front, the airflow enters the left air nozzle 510, and when it is subjected to an impact vibration from the right front, the airflow enters the right air nozzle 510.

[0067] After the airflow enters the nozzle 510, it flows into the cylinder seat 508 and pushes the slide rod 504 to extend outward. The extension of the slide rod 504 further pushes the hose clamp 503 to move in the direction of the junction box. The hose clamp 503 drives the inlet and outlet wires to move together with the junction box, thereby preventing the inlet and outlet wires from being in a taut state due to the displacement of the junction box, preventing the inlet and outlet wires from pulling on the wiring points inside the junction box, and ensuring the stability of the wiring.

[0068] At the same time, the movement of the hose clamp 503 causes the slide rod 504, the cylinder seat 508 and the mounting seat 506 on the other side to slide along the movable groove 505, compressing the return spring 507 on the corresponding side. When the impact vibration disappears, the elastic restoring force of the return spring 507 pushes the mounting seat 506 to reset, thereby causing the hose clamp 503 to return to the initial position.

[0069] Example 3

[0070] This embodiment also provides a method for using an anti-seismic bracket for an optical cable junction box, including the following steps:

[0071] S1. Install the fixing seat 101 in the buffer assembly 1 into the preset position through the fixing slots on both sides, and fasten the clamps 4 on the upper and lower sides of the optical cable junction box to complete the assembly and fixing of the junction box and the bracket. Pass the inlet and outlet lines of the junction box through the hose clamp 503, and use tools to gradually tighten the hose clamp 503 to fix the inlet and outlet lines.

[0072] S2. When the junction box is subjected to a horizontal impact, the impact force is transmitted to the slide 104 through the front anti-impact component 3 and the side anti-impact component 2. The slide 104 moves along the guide rod 103 in the impact direction and compresses the transverse spring 105 on the corresponding side. The transverse spring 105 absorbs the impact energy through elastic deformation to achieve horizontal buffering.

[0073] S3. When the junction box is subjected to a vertical impact, the impact force is transmitted to the guide post 106 through the front anti-impact component 3 and the side anti-impact component 2. The guide post 106 moves vertically along the slide 104 and compresses the vertical spring 108 on the corresponding side. The vertical spring 108 absorbs the impact energy through elastic deformation, thereby achieving vertical buffering.

[0074] S4. When the junction box is subjected to a frontal oblique impact, the front anti-impact component 3 drives the movable seat 202 to slide along the arc rod 201, squeezing the corresponding side elastic sheet 203. The side elastic sheet 203 deforms to absorb energy. When the impact is large, the side elastic sheet 203 squeezes the side telescopic bladder 206 through the pressure plate 204. The side telescopic bladder 206 deforms to achieve secondary buffering.

[0075] S5. When the junction box is impacted from the front, the clamp 4 presses the support arm 304, which drives the guide seat 303 to close along the limit rod 302, squeezing the front elastic plate 305. The front elastic plate 305 deforms to absorb energy. When the impact is large, the front elastic plate 305 squeezes the front telescopic bladder 307, and the front telescopic bladder 307 deforms to achieve secondary buffering.

[0076] S6.
