[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figures 1 to 6 As shown, the present invention provides an electrical engineering cable protection device, including a connecting piece 1. The connecting piece 1 is provided with a buckling card slot 1.3, a buckling card projection 1.4 and a plurality of connecting blocks 1.5. The connecting blocks 1.5 are provided with threaded holes. The two connecting pieces 1 are clamped through the buckling card slot 1.3 and the buckling card projection 1.4. At the same time, the connecting blocks 1.5 on the two connecting pieces 1 are connected by threads. Both ends of the connecting piece 1 are provided with connecting grooves 1.2. A plurality of movable grooves 1.6 are arranged on the outer wall circumference of the connecting piece 1 near the connecting grooves 1.2. A spring 2 is arranged in the connecting groove 1.2. One end of the spring 2 abuts against the inner wall of the connecting groove 1.2, and the other end abuts against one end of the movable tube 3. A plurality of clamping blocks 3.1 are arranged on the movable tube 3. The clamping blocks 3.1 can move in the movable grooves 1.6 to realize the connection between the connecting piece 1 and the movable tube 3. The movable tube 3 is a corrugated tube, which is a cylindrical thin-walled corrugated shell with a plurality of transverse corrugations, and can realize the rotation of the movable tube 3, making the rotation effect better. The spring 2 is used to push the movable tube 3, so that the clamping blocks 3.1 on the movable tube 3 are stuck in the movable grooves 1.6. The movable groove 1.6 is an n-shaped structure, and the lengths of the two sides are different. The long-side groove can enable the clamping blocks 3.1 to enter the movable groove 1.6, and the short-side groove can cooperate with the spring 2 to make the clamping blocks 3.1 stuck in the movable groove 1.6.

[0024] In this embodiment, a plurality of buckles 1.1 are arranged on the inner wall circumference of the connecting piece 1. The buckles 1.1 can fix the cables. At the same time, the buckles 1.1 can classify and separate cables of different types and specifications, which can reduce the interference and damage between the cables, facilitate cable inspection, and improve the maintenance efficiency and service life of the cables.

[0025] In this embodiment, a plurality of annular holes are provided on the connecting member 1 between the fastening card slots 1.3 and the fastening card protrusions 1.4. When rainwater enters the connecting member 1 along the fastening gap between the connecting members 1, the annular holes can guide the rainwater in the higher gap to the lower gap at the other end, preventing a large amount of rainwater from entering the connecting member 1.

[0026] Working principle: When in use, the cable is fixed on the buckle 1.1 of the connecting member 1, and the two connecting members 1 are fastened and simultaneously threadedly connected through the threaded holes on the connecting block 1.5 to realize the fixation of the two connecting members 1. The spring 2 is placed in the connecting groove 1.2, and at the same time, the clamping block 3.1 on the movable tube 3 is inserted into the connecting groove 1.2 along the movable groove 1.6, and is clamped in the short side groove of the movable groove 1.6 under the action of the spring 2. The movable tube 3 is a corrugated tube that can rotate freely, making the overall protection device more movable.
