Description

Technical Field

[0001] The utility model relates to the technical field of cable protection devices, in particular to a cable protection device which is easy to install. Background Art

[0002] Cables are an important part of power transmission. Their external protective sheaths can protect the wire cores. In the actual wiring process of cables, it is often necessary to connect two independent cables together to meet long-distance power transmission. After the two cables are connected, the exposed wire cores at the connection need to be fixed and covered to ensure that the two cables can be stably connected as one, and the wire core connection is waterproofed.

[0003] In actual operation, the existing protection of cable connection points usually involves wrapping the exposed cores of two cables together, tightening them with pliers, and then covering the connection of the cores with insulating tape. This not only ensures the waterproof effect of the core connection, but also allows the two independent cables to be firmly connected together.

[0004] However, during the long-term use of the cable after it is connected, since the cable itself has a certain weight, when the cores of the two sections of the cable are wound and fixed, the tension generated by the cable's own weight will pull the core connection point, which may easily cause the cable joint to become loose. Therefore, the present application proposes a cable protection device that is easy to install and can reinforce the cable joint. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that cable joints in the background technology are prone to loose connections, and to propose a cable protection device that can reinforce the cable joints and is easy to install.

[0027] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0028] Example

[0029] like Figures 1-4 When the cable is inserted into the cable barrel 1, the clamping block 6 is pressed against the inner side of the cable barrel 1, and then the cable is clamped and fixed by the multiple clamping blocks 6, ensuring that the cable end can be firmly installed in the cable barrel 1; an external threaded portion 11 is provided on the outer wall of the cable barrel 1 away from the end of the cable protection barrel 2, and an adjusting sleeve 8 is threadedly installed on the external threaded portion 11. The adjusting sleeve 8 is rotated toward the side of the cable protection barrel 2, and then the adjusting sleeve 8 squeezes the clamping block 6, which is convenient for adjusting the position of the clamping block 6 and can fix it, thereby improving the convenience of the cable clamping and fixing operation.

[0030] Furthermore, a covering block 61 is fixedly installed on the top of the clamping block 6, and the covering block 61 is provided with an extrusion slope 611 at one end close to the adjusting sleeve 8, and a covering surface 612 at one end close to the wiring protection tube 2. In the process of the adjusting sleeve 8 moving toward the side of the clamping block 6, the adjusting sleeve 8 first contacts the extrusion slope 611. As the adjusting sleeve 8 continues to move laterally, the clamping block 6 can be pushed toward the inside of the wire fixing barrel 1. When the covering surface 612 is completely covered by the adjusting sleeve 8, the clamping block 6 can be prevented from moving toward the outside of the wire fixing barrel 1, which can not only stably clamp the cable inside the wire fixing barrel 1, but also facilitate operation.

[0031] Secondly, grooves 13 are carved on the two opposite inner side walls of the assembly opening 12, and sliders 62 are fixedly installed on the two outer walls away from the clamping block 6. The sliders 62 are embedded in the matching grooves 13 and slidably connected thereto, ensuring that the clamping block 6 can be stably slid and installed inside the assembly opening 12; after the clamping block 6 is installed inside the assembly opening 12, the limit plate 14 is fixed in the groove 13, and then the slider 62 is limited to prevent the clamping block 6 from falling off from the assembly opening 12; a plurality of rubber studs 63 are fixedly installed on one end of the clamping block 6, and the rubber studs 63 are in close contact with the outer wall of the cable inserted into the wire barrel 1. While ensuring that the cable is firmly clamped, the probability of squeezing and damaging the outer sheath of the cable can be reduced.

[0032] Furthermore, a connecting slot 4 is bored at one end of the wiring protection tube 2, and a locking bolt 7 is threadedly installed on the tube wall of the wiring protection tube 2, one end of the locking bolt 7 is inserted into the inside of the connecting slot 4, and a connecting plug plate 3 is fixedly installed at one end of the above-mentioned wiring protection tube 2 and at a position opposite to the connecting slot 4, and a threaded hole structure is bored on the connecting plug plate 3; when the two protective devices need to be fixed together, the connecting plug plate 3 fixedly installed on one of the wiring protection tubes 2 is inserted into the connecting slot 4 set on the other wiring protection tube 2, and then the connecting plug plate 3 is locked and fixed by the locking bolt 7 to ensure that the two protective devices can be firmly connected as one.

[0033] Secondly, a rubber sealing ring 5 is movably sleeved on the outer wall of the wire barrel 1. When the adjusting sleeve 8 is rotated toward the side of the wiring protection barrel 2, the rubber sealing ring 5 is clamped and fixed between the adjusting sleeve 8 and the wiring protection barrel 2, which can seal the gap at the joint between the two, preventing water from seeping into the gap and entering the interior of the protective device from the assembly port 12, thereby effectively improving its waterproof performance.

[0034] In this embodiment, first, one end of the cable is passed through the wire fixing barrel 1, and it is ensured that the exposed wire core is located in the wiring protection barrel 2, and then the two independent cables are wired, the exposed wire cores at the ends of the two cables are twisted together, and covered with insulating tape for protection to improve the safety of the wire core connection; when the wire cores of the two cables are connected, the wiring protection barrels 2 on the two protective devices are docked together, and at this time the connecting plug board 3 is inserted into the connecting slot 4 to prevent the two wiring protection barrels 2 from rotating with each other, and then the locking bolt 7 is used to lock and fix the connecting plug board 3, so that the two wiring protection barrels 2 can be tightly connected as one, ensuring that the two protective devices can be firmly connected together. At this time, the wire core connection is located in the protective cover structure composed of the two wiring protection barrels 2, which can improve the protection effect of the wire core connection.

[0035] When the two wiring protection barrels 2 are fixed, the adjusting sleeve 8 threadedly installed on the outer wall of the wire fixing barrel 1 is rotated toward the side of the wiring protection barrel 2. In the process of moving the adjusting sleeve 8 toward the side of the wiring protection barrel 2, the pressing block 61 can be squeezed, allowing the pressing block 61 to completely enter the adjusting sleeve 8. At this time, the clamping block 6 is also squeezed and moves inside the wire fixing barrel 1. When the rubber column head 63 is in close contact with the outside of the cable inside the wire fixing barrel 1, the cable can be clamped and fixed, ensuring that the end of the cable close to the wire core can be firmly connected to the wire fixing barrel 1 as a whole; when the two sections of cable are put into use, the tension generated by the weight of the cable itself is affected by gravity and is shared by the wire fixing barrel 1, and the two independently arranged wiring protection barrels 2 have been reinforced so that the two protective devices are always connected together, thereby preventing the tension generated by the weight of the cable itself from pulling on the wire core connection, effectively preventing the cable joint from loosening.

[0036] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
