Description

Technical Field

[0001] This utility model relates to the field of cable protection sleeve technology, specifically to a cable protection sleeve with good anti-detachment effect. Background Technology

[0002] Cable protection sleeves are conduits used to protect cables from external environmental influences, preventing damage caused by friction or corrosion, ensuring safe operation of cables in various environments, and extending cable lifespan. Existing cable protection sleeves are typically secured to the junction box joint with nuts. However, due to insufficient strength, these sleeves often break or loosen at the nut connection. Furthermore, the inner diameter of the cable protection sleeve is larger than the outer diameter of the cable, and there is no fixed connection between the sleeve and the cable. Therefore, the cable protection sleeve can easily detach from the cable, rendering it ineffective in protecting it.

[0003] Therefore, we have designed a cable protection sleeve with good anti-drop effect. Utility Model Content

[0004] The purpose of this utility model is to provide a cable protection sleeve with good anti-drop effect to address the shortcomings of the existing technology and solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable protection sleeve with good anti-drop effect, comprising a sleeve body, wherein an annular groove is provided at fixed intervals on the inner side of the sleeve body, and a silicone block is embedded in each annular groove. A circular through hole is provided in the middle of the silicone block. A steel wire rope is provided on the inner side of each annular groove. One end of the steel wire rope is connected to a small steel wire loop, and the other end of the steel wire rope passes through the middle of the small steel wire loop and the silicone block. The other end of the steel wire rope is connected to a large steel wire loop. The steel wire rope, the small steel wire loop and the large steel wire loop are wrapped with a layer of silicone. Multiple spherical protrusions are distributed at equal intervals on the silicone layer outside the steel wire rope.

[0006] Preferably, the overall outer diameter of the wire rope and the silicone layer is equal to the diameter of the circular through hole on the silicone block.

[0007] Preferably, the overall inner diameter of the small steel wire ring and the silicone layer is larger than the diameter of the spherical protrusion.

[0008] Preferably, the overall outer diameter of the small steel wire ring and the silicone layer is smaller than the width of the annular groove.

[0009] Preferably, the upper and lower edges of the circular through-hole on the silicone block are chamfered.

[0010] Compared with the prior art, this utility model provides a cable protection sleeve with good anti-drop effect, which has the following beneficial effects:

[0011] Compared to traditional cable protection sleeves, this cable protection sleeve with superior anti-detachment effect features a steel wire rope inside its main body. One end of the steel wire rope is connected to a small steel wire loop, and the other end passes through the small steel wire loop and emerges from a circular through-hole in the silicone block on the main body of the sleeve, forming a rope loop. When the cable passes through the rope loop, pulling the steel wire rope tightens the loop and tightly holds the cable, thus preventing the protection sleeve from falling off during use. Furthermore, the steel wire rope is wrapped with a silicone layer, which increases the friction between the rope loop and the cable surface, further preventing the protection sleeve from falling off.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 In this embodiment: a cable protection sleeve with good anti-drop effect includes a sleeve body 1. An annular groove 2 is provided on the inner side of the sleeve body 1 at fixed intervals. A silicone block 3 is embedded in each annular groove 2. The silicone block 3 and the annular groove 2 are sealed. A circular through hole is provided in the middle of the silicone block 3. The upper and lower edges of the circular through hole on the silicone block 3 are chamfered.

[0019] A steel wire rope 4 is provided on the inner side of each annular groove 2. One end of the steel wire rope 4 is connected to a small steel wire loop 5, and the other end of the steel wire rope 4 passes through the middle of the small steel wire loop 5 and the silicone block 3. The other end of the steel wire rope 4 is also connected to a large steel wire loop 6. After the other end of the steel wire rope 4 passes through the small steel wire loop 5, a rope loop can be formed. Pulling the other end of the steel wire rope 4 outward can tighten the rope loop. The tightened rope loop can tightly hug the outside of the cable passing through the sleeve body 1, so that the sleeve body 1 is fixed to the cable, thereby preventing the sleeve body 1 from falling off the cable. The purpose of setting the large steel wire loop 6 is to make it convenient for the user to pull the steel wire rope 4.

[0020] The steel wire rope 4, small steel wire loop 5, and large steel wire loop 6 are all wrapped with a silicone layer 7. The silicone layer 7 on the outside of the steel wire rope 4 has multiple equally spaced spherical protrusions 8. The overall outer diameter of the steel wire rope 4 and the silicone layer 7 is equal to the diameter of the circular through hole on the silicone block 3. The inner wall of the circular through hole on the silicone block 3 can fit tightly against the silicone layer 7 on the outside of the steel wire rope 4, preventing external dust or moisture from entering the interior of the sleeve body 1. The overall inner diameter of the small steel wire loop 5 and the silicone layer 7 is larger than the diameter of the spherical protrusions 8, and the overall outer diameter of the small steel wire loop 5 and the silicone layer 7 is smaller than the width of the annular groove 2. Before the loop formed by the wire rope 4 is tightened, the entire wire rope 4 is located inside the annular groove 2. At this time, the cable will not be obstructed by the wire rope 4 when passing through the sleeve body 1. When the wire rope 4 is pulled outward, the spherical protrusion 8 on the outside of the wire rope 4 can pass through the circular through hole of the silicone block 3 through the deformation of the silicone block 3. After the loop formed by the wire rope 4 is tightened and tightly hugs the cable, the cooperation between the spherical protrusion 8 on the outside of the wire rope 4 and the silicone block 3 can prevent the wire rope 4 from retracting. At the same time, the silicone layer 7 on the outside of the wire rope will be tightly attached to the outside of the cable. The friction of the silicone is large, which can further prevent the sleeve body 1 from falling off the cable.

[0021] The working principle and usage process of this utility model are as follows: When using this cable protection sleeve with good anti-drop effect, after the cable passes through the middle of the sleeve body 1, the steel wire loop 6 is pulled outward with force, so that the rope loop formed by the steel wire rope 4 is tightened and tightly hugs the outside of the cable. At this time, the rope loop fixes the sleeve body 1 and the cable together. Even if the connection between the protective sleeve and the nut breaks or loosens, the sleeve body 1 will not fall off the cable, thus improving the protection capability of the cable. When the cable is to be pulled out of the sleeve body 1, the pulled-out steel wire rope 4 is first forcefully inserted back into the circular through hole on the silicone block 3 to expand the rope loop, and then the cable is pulled out from the sleeve body 1.

[0022] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
