Description

Technical Field

[0001] The utility model relates to the technical field of cable protection, in particular to a communication cable protection tube with a length adjustment function. Background Art

[0002] The cable protection tube is a metal protection tube with a certain mechanical strength and is laid on the outer layer of the cable to prevent the cable from being damaged. It is mainly installed in the area where the communication cable and the power line intersect to prevent the power line from being broken and causing a short circuit accident, thereby protecting the cable, switch, movement board and other equipment from being burned:

[0003] For example, the publication number is CN111509637A, which is a PVC communication optical fiber cable protective sleeve that is easy to install. It relates to the technical field of protective sleeves. In order to solve the problem of slippage, it specifically includes a sleeve body and a sealing joint used in conjunction with the sleeve body. The two sealing joints are symmetrically used in conjunction with the two end faces of the sleeve body. The inner wall of the sleeve body close to the two end faces is provided with a clamping assembly. The sealing joint includes a cable sheath, a transition sleeve, a sleeve bushing, and an inner sealing surface and an outer sealing surface provided on its outer wall. The present invention is provided with a clamping assembly. When the cable is inserted, the two clamping blocks can be separated from each other by pulling two pull wires. After the cable is inserted, the pull wires are subsequently released. At this time, under the tension of the spring, the hinges of the first hinge rod and the second hinge rod are close to each other, so that the two clamping blocks are close to each other until the cable is firmly clamped, which can effectively prevent the sleeve body from slipping.

[0004] In the actual use of the cable protection tubes in the above documents, the inner wall of the tube body is mostly unable to make close contact with the outer side of the cable. At the same time, when the cable protection tube is subjected to external impact, the buffering and protection effect of the cable inside is poor.

[0005] The cable protection tubes in the above documents are mostly of fixed length, but the cables have different lengths during use. The cable protection tubes of fixed length cannot fully protect cables of different lengths, and have certain limitations.

[0006] Therefore, we propose a communication cable protection tube with length adjustment function to solve the above-mentioned problems. Utility Model Content

[0007] The purpose of the utility model is to provide a communication cable protection tube with a length adjustment function to solve the problem that the cable protection tube proposed in the above background technology has poor buffering protection effect on the inner cable when subjected to external impact and the cable protection tube of fixed length cannot fully protect cables of different lengths.

[0008] To achieve the above object, the utility model provides the following technical solution: a communication cable protection tube with a length adjustment function, comprising a tube body, wherein a movable groove is provided inside the tube body, and the tube body is nested and connected to the outside of the communication cable, and a magnetic strip ring is nested and connected to the outside of the tube body;

[0009] An upper docking block, wherein the upper docking block is fixedly connected to the upper side of the pipe body, and a lower docking block is fixedly connected to the lower side of the pipe body, and a clamping mechanism is provided between the lower docking block and the upper docking block for stably docking the pipe body;

[0010] A limit rod is fixedly connected to the inside of the movable groove, and a movable block is nested and connected to the outside of the limit rod, and an iron block is fixedly connected to the inside of the movable block. A clamping mechanism for buffering and protecting the communication cable is also provided between the outside of the limit rod and the inner wall of the tube body.

[0011] Furthermore, the engaging mechanism comprises a card slot, which is arranged inside the upper docking block, and a card block is fixedly connected to the outer side of the lower docking block.

[0012] Furthermore, the upper docking blocks and the lower docking blocks are each provided with four groups in a circular array about the center point of the tube body, and the clamping blocks can be nested and connected inside the clamping slots.

[0013] Furthermore, the clamping mechanism includes a buffer spring, which is fixedly connected to the outer side of the movable block, and the other end of the buffer spring is fixedly connected to a connecting plate, and the inner side of the connecting plate is fixedly connected to an elastic sheet, and the elastic sheet is nested and connected to the peripheral side of the movable block, and the outer side of the connecting plate is fixedly connected to a clamping plate, and the clamping plate is nested and connected inside the tube body.

[0014] Furthermore, the movable block forms a sliding structure with the limit rod through magnetic adsorption of the iron block and the magnetic strip ring, the connecting plate forms a sliding structure through a buffer spring, and the inner side of the clamping plate is designed to be arc-shaped.

[0015] Furthermore, a flexible airbag is fixedly connected to the inner wall of the tube body, an air supply sleeve is fixedly connected to the inner side of the movable groove, a push rod is nested inside the air supply sleeve, a docking tube is passed through and connected between the air supply sleeve and the flexible airbag, and a rotating rod is hinged between the push rod and the connecting plate.

[0016] Furthermore, the push rod forms a sliding structure with the air supply sleeve through the rotating rod, the flexible airbag is connected with the air supply sleeve through the docking tube, and the air supply sleeve has two groups symmetrically arranged up and down about the center point of the limiting rod.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The user aligns the upper docking block and the lower docking block of the two tubes, and rotates the two tubes so that the clamping block rotates and docks into the inside of the clamping slot. At this time, the two tubes can be spliced. The user can choose the number of tubes to be spliced ​​according to the length of the cable, so as to protect the cable;

[0019] 2. The shorter tubes are butt-jointed and assembled so that the length of the tubes can be changed according to different cables, thereby fully protecting the cables;

[0020] 3. After the cable is connected to the inside of the tube body, the magnetic strip ring can be set on the outside of the tube body. At this time, the iron block is magnetically adsorbed by the magnetic strip ring, which can drive the movable block to move outward, so that the elastic sheet is elastically deformed and does not engage with the movable block. At this time, the buffer spring will push the connecting plate to move outward, and drive the clamping plate to move outward through the connecting plate, so that the clamping plate clamps the cable to prevent the cable from loosening;

[0021] 4. When the clamping plate clamps the cable, the buffer spring is in a contracted state. When an impact force occurs on the outside of the tube body, the buffer spring will buffer the impact force and further protect the cable inside;

[0022] 5. When the connecting plate moves under the push of the buffer spring, it will synchronously drive the two sides of the rotating rod to rotate, and push the push rod to slide inside the air supply sleeve through the rotating rod. While the push rod moves, it will supply air to the inside of the flexible airbag through the docking tube, thereby expanding the flexible airbag. The expanded flexible airbag is connected to the cable, which can further provide flexible protection for the cable. BRIEF DESCRIPTION OF THE DRAWINGS
