Description

Technical Field

[0001] The utility model relates to the technical field of cable sleeve protection, in particular to a cable with a protective tube with adjustable diameter. Background Art

[0002] A cable protection tube refers to a metal protection tube with a certain mechanical strength that is laid on the outer layer of the cable to prevent the cable from being damaged. Currently, the most common cable protection tube is just a simple metal tube.

[0003] According to the Chinese patent application number: CN202220627889.6, a cable protection tube with an elastic protective structure is disclosed, comprising two symmetrical half-tube bodies, each of which is provided with an elastic protective mechanism; the cable protection tube with an elastic protective structure is provided with an elastic protective mechanism: when the external extrusion force acts on the force-bearing plate, the spring can be compressed, and under the compression of the spring, the extrusion force on the semi-ring body and the semi-tube body can be reduced, thereby protecting the semi-tube body, avoiding deformation of the semi-tube body, etc., and also protecting the cable; the cable protection tube with an elastic protective structure is provided with a fixing plate and a stop block, etc.: that is, when the cable passes between the two half-tube bodies, the cable is clamped and fixed by the two stops, thereby fixing the cable, avoiding friction between the cable and the half-tube body, and protecting the cable.

[0004] At present, a cable protection tube with an elastic protection structure still has some shortcomings. For example, when the protection tube protects cables of different diameters, the internal stopper cannot be adjusted to a suitable size, and the applicability is small. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a cable with a protective tube with adjustable diameter, which solves the problem that when the protective tube protects cables of different diameters, the internal stopper cannot be adjusted to a suitable size and has low applicability.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A cable with a protective tube with an adjustable diameter comprises: a protective tube, wherein two fixing plates are arranged inside the protective tube, and the inner circular wall surface of the fixing plates is provided with a protective layer; an adjusting component, wherein the inner circular wall surface of the protective tube is provided with an adjusting component for adjusting the fixing plates, and the adjusting component comprises a plurality of mounting holes, wherein the plurality of mounting holes are all opened on the outer circular wall surface of the protective tube, a telescopic cylinder is fixedly installed inside the mounting holes, a spring is arranged inside the telescopic cylinder, a telescopic rod is provided on a movable sleeve inside the telescopic cylinder, a limit block is arranged inside the telescopic cylinder, and the telescopic rod is fixedly connected to the limit block.

[0008] By adopting the above technical solution and setting an adjustment component, when in use, the fixing plate fixes the cable to prevent the cable from falling off easily. When inserting, the staff first presses the fixing plate inside the protective tube. At this time, the spring is in a compressed state, and then the cable is inserted into the protective tube. After loosening the fixing plate, the spring drives the telescopic rod to pop out, thereby driving the fixing plate to fix, so that the protective tube can fix cables of different diameters, thereby improving the applicability of the protective tube.

[0009] Preferably, two mounting blocks are fixedly mounted on the inner circular wall of the protection tube, a mounting groove is provided on one side of the mounting block, a through opening is provided on one side of the fixing plate, and a plurality of rollers are rotatably mounted inside the mounting groove.

[0010] By adopting the above technical solution and setting rollers, when the cable needs to pass through the protective tube, the staff first presses and expands the internal fixing plate to allow the mounting block to pass through the fixing plate through the through-hole, and the staff then pulls and tugs the cable in the protective tube from the other end of the protective tube. The roller on the inner wall of the protective tube contacts the cable to prevent friction between the cable and the inner wall of the protective tube, which may cause damage to the cable sheath.

[0011] Preferably, a plurality of pressure-resistant balls are provided on the outer circumferential wall surface of the protection tube.

[0012] By adopting the above technical solution and arranging the anti-pressure balls, when the protective tube is subjected to external force, the anti-pressure balls can buffer the force, thereby improving the pressure resistance of the protective tube and preventing the protective tube from being easily damaged after being subjected to pressure.

[0013] Preferably, a waterproof layer is provided on the outside of the protection tube.

[0014] By adopting the above technical solution and providing a waterproof layer, when the protective pipe is pre-buried underground, groundwater is prevented from penetrating into the interior of the protective pipe and causing damage to the cable.

[0015] Preferably, a wear-resistant layer is provided outside the waterproof layer.

[0016] By adopting the above technical solution and providing a wear-resistant layer, the wear-resistant layer can protect the protective tube, thereby reducing damage to the internal structure under the protective tube, thereby increasing the service life of the protective tube.

[0017] Preferably, pull blocks are fixedly mounted on both sides of the fixing plate.

[0018] By adopting the above technical solution and providing a pull block, when the cable passes through the protective tube, the staff can use the pull block to pull the fixed plate inside the protective tube to expand it, which is convenient for the staff to use.

[0019] In summary, the utility model mainly has the following beneficial effects:

[0020] By setting an adjustment component, when in use, the fixing plate fixes the cable to prevent the cable from falling off easily. When inserting, the staff first presses the fixing plate inside the protective tube. At this time, the spring is in a compressed state, and then the cable is inserted into the protective tube. After loosening the fixing plate, the spring drives the telescopic rod to pop out, thereby driving the fixing plate to fix it, so that the protective tube can fix cables of different diameters, thereby improving the applicability of the protective tube.

[0021] By setting up rollers, when the cable needs to pass through the protective tube, the staff first presses and expands the internal fixing plate to allow the mounting block to pass through the fixing plate through the through-hole. The staff then pulls and tugs the cable in the protective tube from the other end of the protective tube. The rollers on the inner wall of the protective tube contact the cable to prevent friction between the cable and the inner wall of the protective tube, which would cause damage to the cable sheath.
