Description

Technical Field

[0001] The utility model relates to the technical field of protection tubes, in particular to a cable protection tube. Background Art

[0002] Cable protection tubes are mainly installed at cable intersections to prevent power line disconnection and short circuit accidents, thereby achieving the purpose of protecting cables. However, most current protection tubes have a simple structure, usually using only plastic pipes to be sleeved on the required cable intersections. Subsequent disassembly is difficult, and the waterproof effect is also average. In view of this, it is necessary to improve the current protection tubes to solve the above problems.

[0003] The above information disclosed in this Background section is only for understanding the background of the present inventive concept and therefore it may contain information that does not constitute prior art. Utility Model Content

[0004] The purpose of the present utility model is to provide a cable protection tube to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A cable protection tube comprises two protection tube bodies and two inner sleeves, wherein flange portions are provided on opposite sides of the two protection tube bodies, and the flange portions of the two opposing protection tube bodies are detachably connected by bolts and nuts;

[0007] A heat shrink tubing is provided on the outside of the protective tube body;

[0008] An inner sleeve is embedded in the interior of the protective tube body, and the inner sleeve includes a sleeve portion and an annular portion. An embedded step portion is provided on one side of the protective tube body close to the heat shrink tube, and the annular portion of the inner sleeve is embedded in the embedded step portion.

[0009] In addition, a preferred structure is that the outer wall of the protective tube body is provided with a frosted portion, and the frosted portion of the protective tube body and the inner wall of the heat shrinkable tube are tightly fitted to each other.

[0010] In addition, a preferred structure is that the protective tube body and the flange portion are an integrally formed structure, and the protective tube body and the flange portion are made of fiberglass reinforced plastic.

[0011] In addition, a preferred structure is that the inner sleeve is made of PVC material, and the thickness of the sleeve is 1mm-3mm.

[0012] In addition, a preferred structure is that the inner wall of the annular portion of the inner sleeve is provided with an arc-shaped chamfer.

[0013] The beneficial effects of the utility model are:

[0014] In the utility model, by using a bolt and nut connection method between the flange parts on the opposite sides of the two protective tube bodies, the protective tube can be easily disassembled and assembled, which is convenient for cable wiring. A heat shrink sleeve is also provided on one side of the protective tube body. When subsequently subjected to hot air and high-temperature operation, the heat shrink sleeve can be tightly wrapped around the cable, thereby improving the moisture-proof and dust-proof effects. By providing an inner sleeve of PVC material in the protective tube body, not only the insulation effect is improved, but also a certain waterproof effect is achieved, thereby better improving the scope of application of the cable protective tube.

[0022] Reference Figure 1-3 A cable protection tube comprises two protection tube bodies 1 and two inner sleeves 6. The two protection tube bodies 1 are provided with flange portions 11 on opposite sides thereof, and the flange portions 11 of the two opposite protection tube bodies 1 are detachably connected by bolts 51 and nuts 52.

[0023] With this design, the flanges 11 are first arranged on opposite sides of the two protective tube bodies 1 and are detachably connected by bolts 51 and nuts 52 that screw together. This makes it easy for the operator to assemble and disassemble the protective tube bodies 1 and also facilitates the cable routing operation.

[0024] In other embodiments, the protective tube body 1 and the flange portion 11 are an integrally formed structure, and the protective tube body 1 and the flange portion 11 are made of fiberglass reinforced plastics;

[0025] This design firstly designs the protective tube body 1 and the flange portion 11 as an integrally formed structure, which can be easily processed in batches. At the same time, the protective tube body 1 and the flange portion 11 are designed to be made of glass fiber reinforced plastics, which has the advantages of being lightweight, high-strength, heat-resistant, corrosion-resistant, and having good insulation properties, thus better meeting the manufacturing requirements of protective tubes for cable use.

[0026] A heat shrink tubing 3 is provided on the outside of the protective tube body 1;

[0027] In other embodiments, the outer wall of the protective tube body 1 is provided with a frosted portion 2, and the frosted portion 2 of the protective tube body 1 and the inner wall of the heat shrinkable tube 3 are closely fitted to each other;

[0028] With this design, the frosted portion 2 is first placed outside the protective tube body 1, and then the inner wall of the heat shrink tube 3 is fitted with the frosted portion 2 of the protective tube body 1. After subsequent hot air and high-temperature operation, the heat shrink tube 3 can be tightly wrapped around the cable, improving moisture and dust resistance.

[0029] An inner sleeve 6 is embedded in the protective tube body 1 , and the inner sleeve 6 includes a sleeve portion 61 and an annular portion 62 . An embedded step portion 4 is provided on one side of the protective tube body 1 close to the heat shrinkable tube 3 , and the annular portion 62 of the inner sleeve 6 is embedded in the embedded step portion 4 .

[0030] In other embodiments, the inner sleeve 6 is made of PVC, and the thickness of the sleeve 6 is 1 mm to 3 mm. The inner wall of the annular portion 62 of the inner sleeve 6 is provided with an arc-shaped chamfer.

[0031] With this design, firstly, an inner sleeve 6 made of PVC material is arranged inside the protective tube body 1, which not only improves the insulation effect but also has a certain waterproof effect;

[0032] Furthermore, an arc-shaped chamfer is provided on the inner wall of the annular portion 62 of the inner sleeve 6, which can prevent the right angle from scratching the cable when the cable is threaded and wired;

[0033] In this embodiment, by using a bolt and nut connection method between the flange parts on the opposite sides of the two protective tube bodies, the protective tube can be easily disassembled and assembled, which is convenient for cable wiring. A heat shrink tubing is also provided on one side of the protective tube body. After subsequent hot air and high-temperature operation, the heat shrink tubing can be tightly wrapped around the cable, thereby improving the moisture-proof and dust-proof effects. By providing an inner tubing made of PVC material in the protective tube body, not only the insulation effect is improved, but also a certain waterproof effect is achieved, thereby better improving the scope of application of the cable protective tube.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
