Description

Technical Field

[0001] The utility model relates to the field of protective sleeves, in particular to a porous flexible protective sleeve. Background Art

[0002] Cable protection tubes are protective tubes with a certain mechanical strength that are laid on the outer layer of cables to prevent them from being damaged. Cable protection tubes are mainly installed in areas where communication cables and power lines intersect to prevent short circuit accidents caused by power line disconnection, which would cause communication cables and steel wire ropes to be electrified, so as to protect cables, switches, movement boards, and even the entire machine from being burned out, and also play a certain role in isolating the magnetic field interference of power lines.

[0003] Most existing cable protection sleeves can only be used for one cable and cannot be used for multiple cables. If three cables are directly placed in the existing cable protection sleeve, the cable will not fit tightly and will be twisted, and the force after bundling will be difficult to balance and stabilize. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a porous flexible protective sleeve.

[0005] The technical solution of this utility model is as follows:

[0006] A porous flexible protective sleeve comprises two semi-circular tubes which are detachably mounted and which form a hollow protective tube body when combined. The inner wall of the semi-circular tube is provided with two arc-shaped grooves, and a convex portion is formed between the two arc-shaped grooves. The convex portion is combined with the inner wall to limit the internal cables.

[0007] One end of the semicircular tube body is a large joint, and the other end is a small joint. When multiple protective tube bodies are connected, the large joint of the front section can be sleeved on the small joint of the rear section.

[0008] The outer surfaces of the two semicircular tubes are provided with binding grooves, and the two semicircular tubes can be bound together by a binding belt.

[0009] One of the semicircular tubes is provided with convex strips and concave grooves on both sides, and the other semicircular tube is provided with concave grooves and convex strips at corresponding positions on both sides. The convex strips of the two semicircular tubes are embedded in the concave grooves for easy positioning.

[0010] An annular protrusion is provided on the inner wall of the large joint, and an annular groove is provided on the corresponding position of the outer wall of the small joint. After splicing, the annular protrusion is inserted into the annular groove to achieve fixed positioning and maintain the stability and reliability of the connection. A bundling groove is also provided on the outside of the large joint, and the force is applied by bundling with a bundling belt to make the convex and concave connection at the joint secure.

[0011] Technical effects and advantages of the utility model:

[0012] It can protect multiple cables at the same time, making them fit tightly against the inner wall of the protective casing at the same time. After external bundling, the force is balanced and stable, which can disperse the impact force and protect the normal operation of the cables in all directions. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Embodiment 1

[0018] like Figure 1-Figure 4 A porous flexible protective sleeve shown includes two semicircular tubes 11, which are detachably installed and are combined to form a hollow protective tube body 1; the inner wall of the semicircular tube is provided with two arc-shaped grooves 12, and a protrusion 13 is formed between the two arc-shaped grooves; the protrusion combined with the inner wall can limit the internal cables.

[0019] Furthermore, one end of the semicircular tube body is a large joint 2, and the other end is a small joint 3. When multiple protective tube bodies are connected, the large joint of the previous section can be put on the small joint of the next section.

[0020] Furthermore, a binding groove 14 is provided on the outer surface of the two semi-circular tubes, and the two semi-circular tubes can be bound together by a binding tie.

[0021] Furthermore, one of the semicircular tubes is provided with a convex strip 15 and a concave groove 16 on both sides, and the other semicircular tube is provided with a concave groove and a convex strip at corresponding positions on both sides, and the convex strips of the two semicircular tubes are embedded in the concave grooves for easy positioning.

[0022] Embodiment 2

[0023] During construction, the three cables 4 are brought close together, and then two semicircular tubes are sleeved outside the three cables, and then the two semicircular tubes are tied together with a binding belt.

[0024] When lengthening is required, the large joint of the next section is sleeved on the small joint of the previous section, and then the two semicircular tubes of the next section are tied together with a cable tie.

[0025] Furthermore, an annular protrusion 21 is provided on the inner wall of the large joint 2, and an annular groove 31 is opened at a corresponding position on the outer wall of the small joint 3.
