Description

Technical Field

[0001] The invention relates to the technical field of communication optical cable joint boxes, in particular to an extrusion device for sealing an optical cable joint box and an optical cable joint box. Background Art

[0002] In recent years, with the rapid development of the communications industry, the optimization and upgrading of communications equipment such as optical cable splice boxes have also become increasingly rapid. Optical cable splice boxes are splice protection devices that provide optical, sealing and mechanical strength continuity between adjacent optical cables. Due to the diversity of optical cable splice boxes in various usage scenarios (such as underground, pipeline, overhead, and wall-mounted), the quality of their sealing performance (preventing the infiltration of moisture and other contaminants) is particularly important in communication networks.

[0003] The sealing principle of mechanical optical cable junction boxes in the industry is basically the same, which is divided into two parts: an elastic component and an extrusion structure. The elastic component is squeezed by the extrusion structure to deform after being compressed, thereby filling the gap between the optical cable and the box body to achieve the sealing performance of the optical cable and the box body. The simplest commonly used extrusion method is to directly compress the cable with a clamp and screws, and then cover the box and fix it with screws. However, the existing extrusion device cable is only tight at the clamp connection at both ends, but there is still a large space between the cable and the junction box between the clamps at both ends, which is easy to get water in. After long-term use, as long as one end of the clamp is loose, it will cause water seepage inside the junction box. This extrusion method has poor protection, the cable is easy to loosen, and only the end of the outlet line is simply squeezed for protection, and the waterproof effect and fixation effect are poor. Summary of the invention

[0004] In order to solve the problems that the existing squeezing device has poor squeezing protection effect and relatively single function, the present invention provides a squeezing device for sealing an optical cable joint box and an optical cable joint box.

[0005] The present invention provides an extrusion device for sealing an optical cable joint box and an optical cable joint box adopting the following technical solutions:

[0006] An extrusion device for sealing an optical cable joint box and an optical cable joint box, comprising:

[0007] An extrusion assembly, wherein the extrusion assembly is embedded in the optical cable junction box, and the extrusion assembly comprises a double-layer storage box and a rotating rod, wherein one end of the rotating rod is coaxially rotatably connected to the inner wall of the double-layer storage box, and the outer wall of the rotating rod is coaxially fixedly connected with a rotating ring and a driving gear, wherein the rotating ring and the driving gear are distributed on both sides of the inner and outer sides of the double-layer storage box, and the outer side of the driving gear is meshedly connected with a plurality of driven gears rotatably connected to the inner wall of the double-layer storage box;

[0008] A squeezing mechanism, the squeezing mechanism is arranged on the inner side of the driven gear, the squeezing mechanism includes a fixing frame, the fixing frame is fixedly connected to the inner wall of one layer of the double-layer storage box, and an inner shaft is rotatably connected to the fixing frame, one end of the inner shaft is coaxially fixedly connected to the driving gear, a ball head universal joint is fixedly connected between adjacent inner shafts, a tooth plate meshing with the driving gear is slidably connected to the fixing frame, and one end of the tooth plate close to the inner side of the fixing frame is detachably connected to a clamping plate;

[0009] Inner ring gears, the inner ring gears are fixedly connected to the inner wall of the driven gear;

[0010] An auxiliary gear, the auxiliary gear is rotatably connected to the inner wall of the double-layer storage box, and the auxiliary gear is meshed with the inner ring gear, the auxiliary gear is arranged between the inner ring gear and the fixed frame, and a connecting rod is connected between the auxiliary gear and the other end of one of the tooth plates;

[0011] The water absorbing mechanism is arranged on another layer of the double-layer storage box, and the top end of the clamping plate extends to a layer of the double-layer storage box accommodating the water absorbing mechanism and is transmission-connected with the water absorbing mechanism.

[0012] By adopting the above technical scheme, the problems of poor extrusion protection effect and relatively single function of the existing extrusion device are solved by the extrusion mechanism. Specifically, the cable is directly passed through the double-layer storage box, and the rotating rod is rotated to drive the driving gear of the extrusion mechanism to rotate. Through the meshing transmission between the driving gear and the driven gear, each driven gear is driven to rotate synchronously, so that the inner ring gear rotates synchronously, and the meshing transmission between the inner ring gear and the auxiliary gear drives the auxiliary gear to rotate. The auxiliary gear drives the connecting rod to reciprocate, so that a tooth plate in the extrusion mechanism is driven to move through the movement of the connecting rod, and the meshing transmission between the tooth plate and the driving gear makes the inner shaft rotate. The ball head universal joint ensures that each inner shaft and the driving gear rotate synchronously, and then ensures that each tooth plate moves synchronously. The cable can be clamped by the clamping plate. During the clamping process, the clamping plate drives the water absorption mechanism to unfold, completes the covering and waterproofing of the blank area, and improves the waterproof effect of the extrusion device. It can not only ensure the extrusion and fixing effect of the cable, but also improve the waterproof effect.

[0013] Optionally, the water absorption mechanism includes a center rod, both ends of the center rod are rotatably connected to the inner wall of another layer of the double-layer storage box, a storage roller is coaxially rotatably connected to the outer side of the center rod, and absorbent cotton cloth is rolled up and stored on the outside of the storage roller. One end of the absorbent cotton cloth is fixedly connected to a locking hook, and the locking hook is connected to the splint bolt. A reset spring is arranged between the outer wall of the storage roller and the inner wall of another layer of the double-layer storage box, and the reset spring is sleeved on the outer side of the center rod.

[0014] By adopting the above technical solution, the absorbent cotton cloth is moved and unfolded by the movement of the splint and the locking hook to cover the blank area between the cable and the optical cable junction box after the cable is compressed, thereby effectively reducing the harm caused by rainwater penetration and ensuring the safety of the structure inside the optical cable junction box. The return spring is used to facilitate the rotation of the storage roller to recycle the absorbent cotton cloth.

[0015] Optionally, the width of the absorbent cotton cloth is greater than the width of the splint, and the heights of adjacent locking hooks are different.

[0016] By adopting the above technical solution, by setting the width of the absorbent cotton cloth and the height of the locking hook, adjacent absorbent cotton cloths are staggered, thereby providing protection without dead angles on the plane and improving the waterproof effect.

[0017] Optionally, the double-layer storage box is provided with an inlet hole and an outlet hole, and a movable filling component is arranged on the top side of the outlet hole, the movable filling component includes an arc-shaped rotating block and flexible filling cotton, a connecting rod is transmission-connected between the arc-shaped rotating block and the rotating ring, the flexible filling cotton is elastic, and the flexible filling cotton is fixedly connected to the inner wall of the arc-shaped rotating block.

[0018] By adopting the above technical solution, the connecting rod is driven to rotate by the rotation of the rotating rod, and the connecting rod drives the arc-shaped rotating block to rotate synchronously, so that the flexible filling cotton stored in the optical cable junction box is released. After the flexible filling cotton loses the extrusion resistance, it expands and fills the outside of the cable, which can not only squeeze the cable, but also improve the waterproof effect, avoid rainwater penetration, and improve safety.

[0019] Optionally, the outer wall of the rotating rod is fixedly connected to a limiting ring, and a positioning hole is formed on the limiting ring.

[0020] By adopting the above technical solution, the limiting ring can limit the rotating rod after the rotating rod completes the rotation, preventing the rotating rod from rotating at will, thereby ensuring the stability of the cable compression.

[0021] Optionally, the height of the clamping plate is higher than the height of the fixing frame, and the clamping plate is slidably connected to the inner wall of the double-layer storage box.

[0022] By adopting the above technical solution and setting the movement mode of the clamping plate height, the clamping plate can stably stretch out the absorbent cotton cloth.

[0023] Optionally, the outer wall of the arc-shaped rotating block is integrally and fixedly connected with a protruding block extending to the outside of the outlet pipe.

[0024] By adopting the above technical solution, the position of the arc-shaped rotating block can be limited by the protruding block to prevent it from rotating randomly and separating from the outlet tube.

[0025] The present invention also provides an optical cable splice box, which comprises:

[0026] A base, wherein a double-layer storage box is embedded in the base, the base is provided with an inlet pipe and a plurality of outlet pipes, the outlet pipe is provided with a cavity, the arc-shaped rotating block is rotatably connected to the inner wall of the cavity, the base is a folding structure, and a lock buckle is provided on the outer wall of the base;

The optical cable storage plate is convenient for cable routing and storage, and through the setting of a multi-position card board, multiple optical cable storage plates can be installed to increase the storage capacity of cables.

[0029] Optionally, the optical cable storage plate is movably connected with an inner cover plate on a side away from the receiving plate, and a wire bundle frame is detachably connected to the outer side of the column.

[0030] By adopting the above technical solution, the optical cable storage board can be protected by the inner cover plate to prevent debris from entering the optical cable storage board at will. The cable outlet can be restricted by the cable bundle frame to avoid cable entanglement and facilitate management.

[0031] Optionally, the opening heights of adjacent installation grooves are different, and at least two sealing rubber rings are provided on the inner wall of the outlet pipe, and the two sealing rubber rings are distributed on both sides of the arc-shaped rotating block along the axial direction of the outlet pipe.

[0032] By adopting the above technical solution and setting the installation groove, a height difference is left between adjacent optical cable storage plates, thereby facilitating the disassembly and assembly of the optical cable storage plates, and improving the waterproof effect of the outlet pipe through the sealing rubber ring.

[0033] In summary, the present invention includes at least one of the following beneficial technical effects:

[0034] The problems of poor extrusion protection effect and relatively single function of the existing extrusion device are solved by the extrusion mechanism. Specifically, the cable is directly passed through the double-layer storage box, and the rotating rod is rotated to drive the driving gear of the extrusion mechanism to rotate. Through the meshing transmission between the driving gear and the driven gear, each driven gear is driven to rotate synchronously, so that the inner ring gear rotates synchronously, and the meshing transmission between the inner ring gear and the auxiliary gear drives the auxiliary gear to rotate. The auxiliary gear drives the connecting rod to reciprocate, so that a tooth plate in the extrusion mechanism is driven to move through the movement of the connecting rod, and the inner shaft rod is rotated through the meshing transmission between the tooth plate and the driving gear. The ball head universal joint ensures that each inner shaft rod and the driving gear rotate synchronously, and then ensures that each tooth plate moves synchronously. The cable can be clamped by the clamping plate. During the clamping process, the clamping plate drives the water absorption mechanism to unfold, completes the covering and waterproofing of the blank area, and improves the waterproof effect of the extrusion device, which can not only ensure the extrusion and fixing effect of the cable, but also improve the waterproof effect.

[0035] The folded base is fixed by a lock, and the storage plate is convenient for storing excess and long cables. The optical cable storage plate is convenient for routing and storing cables, and multiple optical cable storage plates can be installed through the setting of a multi-position card plate to increase the storage capacity of cables.

[0036] Through the combination of the extrusion assembly and the base, the cable outlets are multi-extruded and waterproofed, which greatly improves the stability of the cable outlets and the waterproofness of the connector cable box, meeting people's usage needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] Reference Figure 1-Figure 8 , an extrusion device for sealing an optical cable splice box, comprising:

[0051] The extrusion assembly 3 is embedded in the optical cable joint box, and the extrusion assembly 3 is combined with the optical cable joint box. The extrusion assembly 3 includes a double-layer storage box 31 and a rotating rod 32. The double-layer storage box 31 is provided to facilitate partitioning of different structures, so that each structure can be linked and not interfere with each other. One end of the rotating rod 32 is coaxially connected to the inner wall of the double-layer storage box 31, and the outer wall of the rotating rod 32 is coaxially fixedly connected with a rotating ring 33 and a driving gear 34. The rotating ring 33 and the driving gear 34 are distributed on both sides of the inner and outer sides of the double-layer storage box 31. Specifically, the rotating ring 33 is arranged on the outer side of the double-layer storage box 31, and the driving gear 34 is arranged inside the double-layer storage box 31 to protect the transmission from being interfered with and stuck by debris. The outer side of the driving gear 34 is meshedly connected with a plurality of driven gears 35 that are rotatably connected to the inner wall of the double-layer storage box 31. The driving gear 34 is driven to rotate by the rotating rod 32 to complete the driving control, and the driving gear 34 and the inner cores of each driven gear 35 complete the transmission;

[0052] The squeezing mechanism 36 is arranged on the inner side of the driven gear 35. The squeezing mechanism 36 includes a fixing frame 361. The fixing frame 361 is fixedly connected to the inner wall of one layer of the double-layer storage box 31. The fixing frame 361 supports other parts of the squeezing mechanism 36. The fixing frame 361 is rotatably connected to an inner shaft rod 362. One end of the inner shaft rod 362 is coaxially fixedly connected to a driving gear 365. A ball head universal joint 363 is fixedly connected between adjacent inner shaft rods 362. A tooth plate 364 meshing with the driving gear 365 is slidably connected to the fixing frame 361. One end of the tooth plate 364 close to the inner side of the fixing frame 361 is detachably connected to a clamping plate 366. The linear motion of the tooth plate 364 is completed through the meshing of the driving gear 365 and the tooth plate 364, so that the cable is compressed to ensure the stability of the cable.

[0053] Inner ring gear 37, the inner ring gear 37 is fixedly connected to the inner wall of the driven gear 35, and the inner ring gear 37 drives the auxiliary gear 38 to move in conjunction with the driven gear 35;

[0054] Auxiliary gear 38, the auxiliary gear 38 is rotatably connected to the inner wall of the double-layer storage box 31, and the auxiliary gear 38 is meshed with the inner ring gear 37, the auxiliary gear 38 is arranged between the inner ring gear 37 and the fixed frame 361, and a connecting rod 39 is connected between the auxiliary gear 38 and the other end of one of the tooth plates 364;

[0055] The water absorption mechanism 4 is arranged on another layer of the double-layer storage box 31 , and the top end of the clamping plate 366 extends to a layer of the double-layer storage box 31 accommodating the water absorption mechanism 4 and is transmission-connected to the water absorption mechanism 4 .

[0056] Specifically, when in use, first pass the cable through the double-layer storage box 31, rotate the rotating rod 32 to drive the driving gear 34 of the extrusion mechanism 36 to rotate, and through the meshing transmission between the driving gear 34 and the driven gear 35, drive each driven gear 35 to rotate synchronously, so that the inner ring gear 37 rotates synchronously, and through the meshing transmission between the inner ring gear 37 and the auxiliary gear 38, drive the auxiliary gear 38 to rotate, and the auxiliary gear 38 drives the connecting rod 39 to reciprocate, so that the movement of the connecting rod 39 drives a tooth plate 364 in the extrusion mechanism 36 to move, and through the tooth plate 364 and the driving gear 365, the tooth plate 364 and the driving gear 365 are moved. The meshing transmission causes the inner shaft rod 362 to rotate. The rotation of one inner shaft rod 362 drives the other inner shaft rod 362 to rotate through the ball head universal joint 363, thereby ensuring that each inner shaft rod 362 and the driving gear 365 rotate synchronously, and then ensuring that each tooth plate 364 moves synchronously. The tooth plate 364 drives the clamping plate 366 to move, and the cable can be clamped by the clamping plate 366. During the clamping process, the clamping plate 366 drives the water absorption mechanism 4 to unfold, completes the waterproof coverage of the blank area, and improves the waterproof effect of the extrusion device, which can not only ensure the extrusion and fixing effect of the cable, but also improve the waterproof effect.

[0057] Reference Figure 7 In the embodiment of the present invention, the water absorption mechanism 4 includes a central rod 41, and both ends of the central rod 41 are rotatably connected to the inner wall of another layer of the double-layer storage box 31. A storage roller 42 is coaxially rotatably connected to the outer side of the central rod 41. The storage roller 42 rolls up and stores absorbent cotton cloth 44. One end of the absorbent cotton cloth 44 is fixedly connected to a locking hook 45. The locking hook 45 is bolted to the splint 366. A reset spring 43 is arranged between the outer wall of the storage roller 42 and the inner wall of another layer of the double-layer storage box 31. The reset spring 43 facilitates the recovery of the absorbent cotton cloth 44. The reset spring 43 is sleeved on the outer side of the central rod 41. The width of the absorbent cotton cloth 44 is greater than the width of the splint 366, and the heights of adjacent locking hooks 45 are different.

[0058] Specifically, the process in which the splint 366 drives the water-absorbing mechanism 4 to unfold is that the movement of the splint 366 drives the locking hook 45 to move synchronously, and the locking hook 45 pulls the absorbent cotton cloth 44 to unfold. It should be noted that the heights of adjacent locking hooks 45 are different. Therefore, when the absorbent cotton cloth 44 is unfolded, the heights of adjacent absorbent cotton cloths 44 are different, and the heights are staggered. In order to cooperate with the different height settings of the locking hooks 45, the center heights of adjacent storage rollers 42 are also different, so that the gap between the two absorbent cotton cloths 44 is filled with the other absorbent cotton cloth 44, thereby ensuring a good waterproof effect.

[0059] Reference Figure 1 and Figure 4In the embodiment of the present invention, a wire inlet hole and a wire outlet hole are provided on the double-layer storage box 31, and a movable filling component is provided on the top side of the wire outlet hole. The movable filling component includes an arc-shaped rotating block 331 and a flexible filling cotton 333. A connecting rod 332 is transmission-connected between the arc-shaped rotating block 331 and the rotating ring 33. The flexible filling cotton 333 is elastic, and the flexible filling cotton 333 is fixedly connected to the inner wall of the arc-shaped rotating block 331. The outer wall of the arc-shaped rotating block 331 is integrally fixedly connected with a protruding block extending to the outside of the wire outlet tube 11 to prevent the arc-shaped rotating block 331 from detaching from the wire outlet tube 11.

[0060] Specifically, the flexible filling cotton 333 is normally stored in the inner cavity of the outlet tube 11. After the cable is passed through, it is tightened with a clamp. The rotating rod 32 drives the rotating ring 33 to rotate, and the rotating ring 33 drives the connecting rod 332 to rotate synchronously, thereby driving the arc-shaped rotating block 331 to rotate, and the flexible filling cotton 333 stored in the inner cavity of the outlet tube 11 is released. After losing the restraint, the flexible filling cotton 333 expands and fills the surrounding area of ​​the cable, effectively squeezing and fixing the cable, and can also perform preliminary waterproofing on this section to improve the sealing effect.

[0061] Reference Figure 4 In the embodiment of the present invention, the outer wall of the rotating rod 32 is fixedly connected to the limit ring 321, and a positioning hole is opened on the limit ring 321. After the position of the rotating rod 32 is determined, a screw is passed through the positioning hole to limit the limit ring 321, thereby preventing the rotating rod 32 from rotating.

[0062] Reference Figure 7 In the embodiment of the present invention, the height of the splint 366 is higher than the height of the fixing frame 361 , and the splint 366 is slidably connected to the inner wall of the double-layer storage box 31 to ensure that the stretching of the absorbent cotton cloth 44 is normal and that the movement of the splint 366 does not hinder the movement of the absorbent cotton cloth 44 .

[0066] Specifically, first pass the cables through the inlet pipe 12 and the outlet pipe 11, and then pass the cables through each optical cable storage plate 27. Then insert the box body 2 between the semicircular and central parts of the base 1, and then fix it with the lock buckle 13. It should be noted that the number of optical cable storage plates 27 is selectively installed according to the actual amount of cables, and the connecting block 22 and the multi-position card plate 23 are installed with screws to ensure the stability of the installation of the optical cable storage plate 27.

After the cables are installed, the inner cover plate 25 is connected, and the outgoing cables are constrained by the wire harness frame 26 to ensure that the amount of cables in each outlet tube 11 is close, but it does not cause excessive congestion of the outlet cables.
