Description

Technical Field

[0001] The present invention belongs to the technical field of cable protection pipes, and specifically refers to a snap - on cable protection pipe that is convenient for installation. Background Art

[0002] A cable protection pipe refers to a metal protection pipe with a certain mechanical strength that is laid on the outer layer of a cable to prevent the cable from being damaged. Cable protection pipes are mainly installed in sections where communication cables cross power lines to prevent power line breakage from causing short - circuit accidents, causing communication cables and wire ropes to be electrified, so as to protect the cable, switch, circuit board, and even the whole machine from being burned out, and also play a certain role in isolating the magnetic field interference of power lines. The current cable protection pipes have a simple structure. During laying, the pipes are generally connected by welding first, and then a square support sleeve is sleeved on the pipes to achieve support. And the support pieces on multiple pipes are connected by pins similar to the mortise - and - tenon structure, enabling multiple pipes to be neatly stacked.

[0003] However, in the prior art, the installation of cable protection pipes is difficult. Especially for laid cables, the integral round pipe needs to be inserted from the end of the cable. If the cable is fixed or has a long length, it is difficult to carry out the pipe - threading construction. And traditional round pipes need to be pre - bent or use elbow fittings, which is time - consuming and may damage the cable.

[0004] The main reason for the inconvenient installation of cable protection pipes is the defect of the traditional connection method. For threaded connection, special tools are required, and it is time - consuming to tighten. When they are not aligned, readjustment is needed. For welded connection, professional welders are required, there is a fire risk in on - site construction, it cannot be disassembled after installation, and the labor cost is high. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that the installation operation of traditional cable protection pipes is relatively inconvenient, increasing the trouble of manual operation, and in case of local damage, the whole needs to be replaced, resulting in a relatively high cost.

[0006] The technical solution adopted by the present invention is as follows:

[0007] A snap - on cable protection pipe that is convenient for installation proposed by the present invention includes a first semi - circular sleeve and a second semi - circular sleeve. The inner wall curvature radii of the two are the same. After combination, they form a complete circular lumen with an inner diameter matching the target cable. The second semi - circular sleeve is arranged above the first semi - circular sleeve. The two sides of the first semi - circular sleeve are fixedly connected with first connecting plates, and positioning rods are fixedly connected to the upper parts of the first connecting plates. The two sides of the second semi - circular sleeve are fixedly connected with second connecting plates that are movably inserted on the positioning rods, and a snap - connection unit is also included.

[0008] Further, the clamping unit includes a clamping seat disposed outside the first connecting plate. A slot is formed in the upper part of the clamping seat, and a limiting groove communicating with the slot is formed in the side wall of the clamping seat. A limiting frame is movably inserted into the slot, a clamping groove is formed in the limiting frame, and an arc-shaped limiting block is inserted into the limiting groove and the clamping groove.

[0009] Further, a U-shaped frame is fixedly connected to the outside of the clamping seat. A movable rod fixedly connected to the arc-shaped limiting block is movably inserted into the U-shaped frame, and a spring is sleeved on the movable rod.

[0010] Further, an L-shaped connecting frame fixedly connected to the clamping seat is installed at the lower part of the first connecting plate through bolts, and an assembly plate integrally formed with the limiting frame is installed at the upper part of the second connecting plate through bolts.

[0011] Further, a first connecting piece is fixedly connected to one end of the first semi-cylindrical sleeve and the second semi-cylindrical sleeve, and a second connecting piece is fixedly connected to the other end of the first semi-cylindrical sleeve and the second semi-cylindrical sleeve.

[0012] Further, a combined groove is formed in the first connecting piece, and a combined convex block matched with the combined groove is fixedly connected to the second connecting piece.

[0013] The beneficial effects achieved by the present invention with the above structure are as follows:

[0014] 1. Installation convenience, no need to thread wires: directly wrap the cable and then snap it together, eliminating the traditional pipe threading step. In areas with dense pipelines or curved sections, it can be installed in segments without overall pipe threading. The snap-on type improves the installation efficiency.

[0015] 2. The split-type sleeve can be replaced locally, only disassembling the damaged section without pulling out the entire cable; and it can be reused: the detachable structure allows the sleeve to be reused. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] As Figure 1 , Figure 2 shown, a snap-connect type cable protection pipe proposed by the present invention for easy installation includes a first semi-circular sleeve 1 and a second semi-circular sleeve 11. The inner wall curvature radii of both are the same. After combination, a complete circular lumen is formed, and the inner diameter matches the target cable. A radial sealing component is continuously distributed along the sleeve docking seam to prevent liquid or dust from invading the lumen. After directly wrapping the cable, it is buckled, saving the traditional pipe-passing step. The second semi-circular sleeve 11 is arranged above the first semi-circular sleeve 1. The two sides of the first semi-circular sleeve 1 are fixedly connected with a first connecting plate 13. The upper part of the first connecting plate 13 is fixedly connected with a positioning rod 14. The two sides of the second semi-circular sleeve 11 are fixedly connected with a second connecting plate 15 that is movably inserted on the positioning rod 14. It also includes a clamping unit.
