DETAILED DESCRIPTION

[0032] Example 1: Please refer to the attached Figure 1-8 A network communication cable joint protection device comprises a protection tube 1, an insulating sleeve 2 is arranged inside the protection tube 1, the insulating sleeve 2 is used to wrap around the outside of the cable to protect the cable joint, both ends of the insulating sleeve 2 are provided with a card slot 3, both ends of the protection tube 1 are rotatably connected with a stripping mechanism 5, and a fixing mechanism 4 is arranged outside the protection tube 1. When the cable is jointed, the end of the cable is placed into the stripping mechanism 5 and the outer skin of the cable is cut by the stripping mechanism 5, and the two stripped cables are inserted into the insulating sleeve 2, and the ends of the two cables are jointed, and then the cables are tightly fixed in the insulating sleeve 2 by the fixing mechanism 4, so as to realize the protection operation of the joints at the ends of the two cables.

[0033] In this embodiment, the insulating sleeve 2 is fixedly installed inside the protective tube 1 by means of a clip-on connection, which is convenient for assembly and installation.

[0034] The fixing mechanism 4 includes two groups of fitting grooves opened on the outer surface of the protective tube 1 and near its two ends, each group of fitting grooves includes three annular rotating fitting grooves 403 arranged at intervals, and a rotating clamping plate 408 is rotatably installed in each rotating fitting groove 403. An adjusting component for driving the rotating clamping plate 408 to swing is provided on the outside of the protective tube 1, and a clamping and fixing arc rod 410 is fixedly connected to one end of the rotating clamping plate 408 away from the adjusting component, and the clamping and fixing arc rod 410 is adapted to the slot 3 on the insulating sleeve 2.

[0035] Two threaded sections 401 are provided on the outer surface of the protection tube 1 symmetrically. Two limiting sliding grooves 402 are provided at the position of each threaded section 401 on the protection tube 1 symmetrically.

[0036] The adjustment assembly includes an internal threaded rotating sleeve 404 threadedly connected at the position of each threaded segment 401 , and a sliding mounting ring 405 is rotatably connected to the side of the internal threaded rotating sleeve 404 close to the corresponding stripping mechanism 5 , and the sliding mounting ring 405 is sleeved on the outside of the protective tube 1 .

[0037] Two limit sliding blocks 411 are fixedly connected to the inner surface of the sliding mounting ring 405 , and the limit sliding blocks 411 are slidably connected to the corresponding limit sliding grooves 402 .

[0038] With such a design, the cooperation between the limiting sliding block 411 and the limiting sliding groove 402 can limit the circumferential position of the sliding mounting ring 405 on the protective tube 1, so that the sliding mounting ring 405 cannot rotate circumferentially, and the sliding mounting ring 405 can be slidably installed on the protective tube 1, which is convenient for assembly and installation, and the cooperation between the limiting sliding block 411 and the limiting sliding groove 402 can guide the movement of the sliding mounting ring 405, thereby improving the stability of the sliding mounting ring 405 during movement.

[0039] The sliding mounting ring 405 is rotatably connected to the internal thread rotating sleeve 404. The internal thread rotating sleeve 404 can be moved by the cooperation of the threaded section 401 during the rotation. At this time, the internal thread rotating sleeve 404 can drive the sliding mounting ring 405 to move axially on the protective tube 1, and the cooperation of the limiting sliding block 411 and the limiting sliding groove 402 is used to guide the movement of the sliding mounting ring 405, so that the sliding mounting ring 405 is more stable when moving, thereby improving the use effect.

[0040] Three mounting seats 406 are fixedly mounted on one side of the sliding mounting ring 405 away from the internal thread rotating sleeve 404 . The three mounting seats 406 are arranged at positions corresponding to the positions of the three rotating clamping plates 408 . Push connecting plates 407 are hingedly connected to the three mounting seats 406 .

[0041] One end of the pushing connecting plate 407 away from the sliding mounting ring 405 is hinged to one end of the corresponding rotating clamping plate 408 away from the clamping fixed arc rod 410 .

[0042] The exterior of the protection tube 1 is fixedly connected to both sides of the rotation fitting groove 403 with fixed blocks 409 , and the middle of the rotation clamping plate 408 is fixedly connected to both sides with hinge shafts, which are rotationally connected to the fixed blocks 409 .

[0043] In this embodiment, the outer surface of the internal thread rotating sleeve 404 is provided with anti-skid patterns, and the anti-skid patterns can increase the friction force of the outer surface of the internal thread rotating sleeve 404 .

[0044] In this embodiment, a protective sleeve is provided on the outer sleeve of the clamping and fixing arc rod 410 , and the protective sleeve can protect the insulating sleeve 2 from being damaged when the clamping and fixing arc rod 410 squeezes the slot 3 on the insulating sleeve 2 .

[0045] With such a design, when two cables need to be connected during use, first insert the connection of the two cables into the inner middle section of the insulating sleeve 2, and make the connection of the two cables tightly connected. At this time, rotate the internal threaded rotating sleeve 404. Since the internal threaded rotating sleeve 404 is threadedly connected to the threaded section 401 on the protective tube 1, after twisting the internal threaded rotating sleeve 404, the internal threaded rotating sleeve 404 can be moved outside the protective tube 1 toward the two ends of the protective tube 1. At this time, the internal threaded rotating sleeve 404 pushes the sliding mounting ring 405 to move toward the two ends of the protective tube 1.

[0046] During the movement, the sliding mounting ring 405 pushes the connecting plate 407 to move toward the direction close to the stripping mechanism 5. Since the rotating clamping plate 408 is rotatably connected to the protective tube 1, the connecting plate 407 is pushed to push the rotating clamping plate 408 to swing along the rotating connection between the hinge axis and the fixed block 409, thereby driving the clamping and fixing arc rod 410 to swing toward the inside of the protective tube 1. At this time, the clamping and fixing arc rod 410 is clamped in the card slot 3, and the two ends of the insulating sleeve 2 are squeezed toward the middle of the protective tube 1, and then the two ends of the insulating sleeve 2 can be tightly pressed against the outer surface of the cable, so that the cable can be fixed, and the cable joint processing is convenient. At the same time, the insulating sleeve 2 is used to wrap the cable joint to protect the cable joint, and the insulating sleeve 2 can also be protected by the protective tube 1 to improve the use effect.

[0047] The peeling mechanism 5 includes two installation sleeves 501 . A rotation limit ring 502 is fixedly connected to one side of the installation sleeve 501 close to the protection tube 1 . The installation sleeve 501 is rotatably installed at both ends of the protection tube 1 through the rotation limit ring 502 .

[0048] The rotation limit ring 502 is provided with an annular groove, and annular protrusions are integrally connected to the inner surfaces of both ends of the protection tube 1. After the rotation limit ring 502 is installed inside the two ends of the protection tube 1, the annular protrusions cooperate with the annular grooves to realize the rotation installation of the installation sleeve 501 at the two end positions of the protection tube 1.

[0049] The installation sleeve 501 is provided with two symmetrically arranged installation slots 511 , and the skinning knife components are rotatably installed in the installation slots 511 .

[0050] The peeling knife assembly includes a rotatable mounting shell 504, which is rotatably mounted in the mounting groove 511. The rotatable mounting shell 504 is provided with a mounting groove 505 inside. The mounting groove 505 is slidably connected to a sliding limit block 506 inside. The sliding limit block 506 is fixedly connected to a peeling cutting knife 508 on one side close to the protective tube 1.

[0051] The side of the peeling and cutting knife 508 away from the sliding limit block 506 penetrates the corresponding side wall of the rotating mounting shell 504, and the peeling and cutting knife 508 and the rotating mounting shell 504 are slidably connected.

[0052] In this embodiment, hinged connecting shafts are fixedly installed on both side surfaces of the rotating mounting shell 504, and hinged countersunk holes are respectively opened on the inner surfaces of both sides of the mounting groove 511. The hinged connecting shafts on the rotating mounting shell 504 are rotatably connected in the corresponding hinged countersunk holes, so that the rotating mounting shell 504 can be rotatably installed in the mounting groove 511, which is convenient for assembly and installation.

[0053] In this embodiment, a blade is provided on a side of the stripping and cutting knife 508 away from the sliding limit block 506 , and the blade is used to cut the outer sheath of the cable.

[0054] A return spring 507 is arranged inside the mounting groove 505, and the return spring 507 is sleeved on the peeling cutting knife 508. One end of the return spring 507 is fixedly connected to the inner wall of the mounting groove 505, and the other end of the return spring 507 is fixedly connected to the sliding limit block 506; the return spring 507 can drive the sliding limit block 506 to reset.

[0055] The sliding limit block 506 is fixedly connected to a push rod 509 on one side away from the peeling cutting knife 508. The other end of the push rod 509 passes through the corresponding side wall of the rotating mounting shell 504 and is fixedly connected to a round handle 510. The push rod 509 and the rotating mounting shell 504 are slidably connected.

[0056] In this embodiment, the outer cover of the round handle 510 is provided with a rubber cover.

[0057] A knife inserting groove 503 is respectively formed on one side wall of the installation through groove 511 close to the protection tube 1 , and the end of the peeling and cutting knife 508 away from the sliding limit block 506 is slidably arranged inside the knife inserting groove 503 .

[0058] With such a design, the stripping mechanism 5 can be used to strip the ends of the cables. First, the joints of the two cables are placed into the interior of the protective tube 1 through the mounting sleeve 501. At this time, the round handle 510 is pulled toward the side away from the protective tube 1, thereby driving the push rod 509 and the sliding limit block 506 to move outward, thereby driving the stripping cutting knife 508 to move out of the knife slot 503. At this time, the rotating mounting shell 504 is rotated toward the direction close to the protective tube 1.

[0059] When the rotating mounting shell 504 is rotated away from the round handle 510 to be perpendicular to the cable, the round handle 510 is pressed downward to drive the pressing rod 509 to move downward, and then the pressing rod 509 can drive the sliding limit block 506 to move toward the side close to the cable, so that the stripping and cutting knife 508 moves toward the side close to the cable. At the same time, the sliding limit block 506 is used to compress the reset spring 507.

[0060] After the stripping cutter 508 is inserted into the outer sheath of the cable on the side away from the round handle 510, the installation sleeve 501 is rotated, and the installation sleeve 501 rotates to drive the stripping cutter 508 to rotate around the cable, so that the outer sheath of the cable can be stripped off, and then the cable is pulled out in the direction away from the protective tube 1, and the outer sheath of the cable is stripped off using the stripping cutter 508 to block it, which is convenient for use.

[0061] In this embodiment, the insulating sleeve 2 is made of an elastic insulating material, preferably a rubber material.

[0062] Working principle: When protecting the cable joints, first put the two cable joints into the protection tube 1 through the installation sleeve 501. At this time, pull the round handle 510 to the side away from the protection tube 1. The round handle 510 drives the pressing rod 509 and the sliding limit block 506 to move outward, thereby driving the stripping cutting knife 508 to move out of the knife slot 503. At this time, rotate the rotating installation shell 504 in the direction close to the protection tube 1.

[0063] When the rotating mounting shell 504 is rotated away from the round handle 510 to be perpendicular to the cable, the round handle 510 is pressed downward to drive the pressing rod 509 to move downward, and the pressing rod 509 drives the sliding limit block 506 and the stripping cutting knife 508 to move toward the direction close to the cable. At the same time, the sliding limit block 506 is used to compress the reset spring 507.

[0064] When the stripping cutter 508 is inserted into the outer sheath of the cable on the side away from the round handle 510, the installation sleeve 501 is rotated. The rotation of the installation sleeve 501 drives the stripping cutter 508 to rotate around the cable, and then the outer sheath of the cable can be stripped off. At this time, the cable is pulled out in the direction away from the protective tube 1, and the outer sheath of the cable is peeled off by using the obstruction of the stripping cutter 508.

[0065] The removed outer skin is then taken out from the protective tube 1, and the peeling knife assembly is reset. At this time, the round handle 510 is pulled to the side away from the protective tube 1, and the round handle 510 drives the peeling cutting knife 508 to move through the pressing rod 509 and the sliding limit block 506, so that the peeling cutting knife 508 is retracted into the installation groove 505. At this time, the sliding limit block 506 pulls the reset spring 507 to extend.

[0066] Then the rotatable mounting shell 504 is rotated to rotate the peeling cutting knife 508 to the position of the knife slot 503, and then the round handle 510 is loosened. At this time, the sliding limit block 506 is pulled to move under the reset force of the reset spring 507, thereby inserting the peeling cutting knife 508 into the knife slot 503, completing the reset work of the peeling knife assembly.

[0067] When connecting two cables, first insert the connection of the two cables into the inner middle section of the insulating sleeve 2, and make the connection of the two cables tightly connected. At this time, rotate the internal threaded rotating sleeve 404. Since the internal threaded rotating sleeve 404 and the threaded section 401 on the protective tube 1 are threadedly connected, the internal threaded rotating sleeve 404 can be moved outside the protective tube 1 toward the two ends of the protective tube 1 after twisting the internal threaded rotating sleeve 404. At this time, the internal threaded rotating sleeve 404 pushes the sliding mounting ring 405 to move toward the two ends of the protective tube 1.

[0068] During the movement, the sliding mounting ring 405 pushes the connecting plate 407 to move toward the direction close to the stripping mechanism 5. Since the rotating clamping plate 408 is rotatably connected to the protective tube 1, the connecting plate 407 is pushed to push the rotating clamping plate 408 to swing along the rotating connection between the hinge axis and the fixed block 409, thereby driving the clamping and fixing arc rod 410 to swing toward the inside of the protective tube 1. At this time, the clamping and fixing arc rod 410 is clamped in the card slot 3, and the two ends of the insulating sleeve 2 are squeezed toward the middle of the protective tube 1, thereby making the two ends of the insulating sleeve 2 tightly pressed against the outer surface of the cable, so that the cable can be fixed, and the cable joint processing is convenient. At the same time, the insulating sleeve 2 is used to wrap the cable joint to protect the cable joint, and the insulating sleeve 2 can also be protected by the protective tube 1 to improve the use effect.

[0069] Example 2: Please refer to the attached Fig. 9 A network communication cable connector protection device can also be used Fig. 9 In the structure shown, the outer surface of the protection tube 1 has no threaded section 401 , but only two groups of sliding grooves. The two groups of sliding grooves are symmetrically arranged, and each group of sliding grooves includes two symmetrically arranged limiting sliding grooves 402 .

[0070] The adjustment component includes two sliding mounting rings 405 sleeved on the outer surface of the protective tube 1, and two limiting sliding blocks 411 are fixedly connected to the inner surface of the sliding mounting rings 405, and the limiting sliding blocks 411 are respectively slidably connected to the corresponding limiting sliding grooves 402; the sliding mounting rings 405 are slidably installed on the protective tube 1 through the cooperation between the limiting sliding blocks 411 and the limiting sliding grooves 402.

[0071] Three mounting seats 406 are fixedly installed on one side of the two sliding mounting rings 405 close to the peeling mechanism 5, and push connecting plates 407 are hinged on the mounting seats 406. The end of the push connecting plate 407 away from the sliding mounting ring 405 is hinged to the end of the corresponding rotating clamping plate 408 away from the clamping fixed arc rod 410.

[0072] In this second embodiment, the overall structure of the rotating engagement groove 403, the rotating clamping plate 408, the fixing block 409, the clamping and fixing arc rod 410, the insulating sleeve 2 and the stripping mechanism 5 is the same as that of the first embodiment described above.

[0073] A plurality of threaded sleeves 6 are movably arranged at the middle position of the two sliding mounting rings 405. The plurality of threaded sleeves 6 are arranged in a ring shape and at intervals along the outer surface of the protective tube 1. Two internal threaded sections with opposite thread rotation directions are provided in the threaded sleeve 6. The two internal threaded sections in the threaded sleeve 6 are respectively threadedly connected with top threaded rods 601. The ends of the two top threaded rods 601 that are away from each other are fixedly connected to the corresponding sliding mounting rings 405.

[0074] With this design, when the threaded sleeve 6 is turned, the threaded sleeve 6 drives the two top-connected threaded rods 601 to move away from or towards each other through the cooperation of the threads, which is convenient for use. When the two top-connected threaded rods 601 move away from each other, the two top-connected threaded rods 601 are used to synchronously push the two sliding mounting rings 405 to move away from each other, which is convenient for use.

[0075] In this embodiment, there are two threaded sleeves 6 , and the two threaded sleeves 6 are symmetrically arranged.

[0076] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
