[0018] like Figure 1-3As shown, a flexible cable protective cover comprises a protective shell 1, which is a rectangular cavity with two ends open, and further comprises an airbag sleeve 2, a support component 3 and a buffer limit component 4. The support component 3 is arranged on the inner wall of the protective shell 1, and the support components 3 are arranged symmetrically in a cross shape. The airbag sleeve 2 is movably connected between the two symmetrical support components 3 and is located at the center of the protective shell 1. The buffer limit component 4 is arranged at the inner wall corner of the protective shell 1 and is connected to the airbag sleeve 2. There is a friction rubber pad 5, and the cable is inserted into the airbag sleeve 2. In order to facilitate the insertion of the cable, the friction rubber pad 5 is arranged in a spiral shape. The protective shell 1 is rotated to make the cable gradually screw into the airbag sleeve 2. The friction rubber pad 5 is made of rubber material, which increases the friction with the cable and flexibly supports the cable and the airbag sleeve 2. The support component 3 limits the outer side of the airbag sleeve 2 on the inner wall of the protective shell 1, and further fixes and limits the airbag sleeve 2 through the buffer limit component 4, and flexibly supports and protects the outer side of the airbag sleeve 2.

[0019] like Figure 1 and Figure 2 As shown, in order to limit the movement of the airbag sleeve 2 and keep it at the center inside the protective shell 1, the support assembly 3 includes a connecting plate 6 and a limiting plate 7. One end of the connecting plate 6 is fixedly connected to the middle of the inner wall of the protective shell 1, and the limiting plate 7 is fixedly connected to the other end of the connecting plate 6. The limiting plate 7 is arranged in an arc shape, and the limiting plate 7 is fixedly connected to the inner wall of the protective shell 1 through the connecting plate 6. The two symmetrical protective plates fit the outer wall of the airbag sleeve 2 to support its outside, so that the airbag sleeve 2 is limited to the center inside the protective shell 1.

[0020] like Figure 2 and 3As shown, in order to increase the pressure resistance and impact resistance of the cable and realize the external force dispersion of the cable, the tube wall of the airbag sleeve 2 is set in a cavity, and the inner wall of the limiting plate 7 is in friction contact with the outer wall of the airbag sleeve 2 through two symmetrical limiting plates. The buffer limiting component 4 includes an airbag column 8 and a connecting pipe 9. The airbag column 8 is fixedly connected to the edge corner of the inner wall of the protective shell 1. One end of the connecting pipe 9 is fixedly connected to the outer wall of the connecting pipe 9 and is connected to the inside of the airbag column 8. The other end of the connecting pipe 9 is fixedly connected to the outer side wall of the airbag sleeve 2 and is connected to the cavity of the inner wall of the airbag sleeve 2. The airbag sleeve 2 is limited. The end face of the airbag column 8 is set in an isosceles right triangle. The two oblique sides of the adjacent right angles of the airbag column 8 are in contact with the protective shell 1. The inner walls of adjacent right-angled sides are fixedly fitted, and the connecting tubes 9 are arranged at uniform intervals along the length direction of the protective shell 1. A rubber valve 10 is provided in the connecting tube 9. The airbag column 8 is connected to the cavity of the inner wall of the airbag sleeve 2 through the connecting tube 9. At the same time, the airbag column 8 supports the protective shell 1 outside the airbag sleeve 2. When the protective shell 1 is subjected to pressure or impact force, the air in each airbag column 8 or a single airbag column 8 enters the cavity of the airbag sleeve 2 through the connecting tube 9. The air between the airbag column 8 and the airbag sleeve 2 circulates with each other to achieve the dispersion of pressure or impact force, and the rubber valve 10 increases the pressure of the circulating air in the connecting tube 9 to improve the supporting force of the airbag column 8 and the airbag sleeve 2.

[0021] During specific use, the operator inserts the cable into the airbag sleeve 2, and the protective shell can be rotated when threading. The protective shell 1 can be made of nylon material, which has strong wear resistance, so that the cable is gradually sheathed on the outer wall of the cable through the spiral friction pad 5;

[0022] During use, when the protective shell 1 is subjected to pressure or impact, the airbag columns 8 at the corners of the protective shell 1 support it, causing the airbag columns 8 to deform. The internal gas enters the airbag sleeve 2 through the connecting tube 9, or flows into other airbag columns 8, thereby increasing the supporting force of other airbag columns 8. By dispersing the flowing air and the reaction force, the buffer is increased to protect the internal cables.

[0023] At the same time, the support component 3 presses the outer wall of the airbag sleeve 2 between adjacent airbag columns 8, limits the diameter of the airbag sleeve 2 after expansion, and maintains a certain pressure on each airbag column 8. Through the rubber valve 10 inside the connecting tube 9, there is a certain resistance when the air inside the airbag column 8 and the air inside the airbag sleeve 2 flow between each other, thereby achieving pressure and impact protection for the cables inside the airbag sleeve 2.

[0024] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents. In short, if those skilled in the art are inspired by the present invention and, without departing from the purpose of the present invention, design structures and embodiments similar to the technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
