[0029] 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.

[0030] As Figures 1-4 shown, this embodiment provides a technical solution: a bend-resistant new energy cable, including a protective outer sleeve 1, both ends of the protective outer sleeve 1 are slidably installed with stabilizing sleeves 11, and both ends of the two stabilizing sleeves 11 away from each other are slidably installed with bend-resistant sleeves 12; inside the bend-resistant sleeve 12, there are equidistantly distributed protective inner sleeves 13 installed, and inside each of the multiple protective inner sleeves 13, there is a cable conductor 14 installed, and the protective inner sleeves 13 are all distributed in an annular structure; on the outer side of the protective outer sleeve 1 and between the two stabilizing sleeves 11, there are sealing and limiting mechanisms 2 installed; the sealing and limiting mechanisms 2 each include a first compression sleeve 21 and a shielding sleeve 22, on the outer side of the protective outer sleeve 1, there are two symmetrically distributed first compression sleeves 21 installed, on one side of each first compression sleeve 21, there is a shielding sleeve 22 installed, and on the side of the shielding sleeve 22 away from the first compression sleeve 21, there is an insulating sleeve 23 installed. The first compression sleeve 21, the shielding sleeve 22, and the insulating sleeve 23 are all located on the outer side of the protective outer sleeve 1. By setting the protective outer sleeve 1, the stabilizing sleeves 11, the bend-resistant sleeves 12, and the second compression sleeve 3 to be used in cooperation, the technical problem that the cable is easily bent when taken out and stored frequently during use is solved. By setting the sealing and limiting mechanism 2, when in use, it is installed on the outer side of the protective outer sleeve 1 in the order of the first compression sleeve 21, the sealing inner pad 24, the shielding sleeve 22, the protective inner pad 25, and the first anti-slip strip 26, solving the technical problem of poor sealing connection effect during the overall use, extending the overall service life of the equipment, and reducing potential safety hazards at the same time.

[0031] Furthermore, as Figures 2-3 shown: on the outer side of the insulating sleeve 23, there are equidistantly distributed first anti-slip strips 26 fixedly connected, between the insulating sleeve 23 and the shielding sleeve 22, there are protective inner pads 25 installed, and between the first compression sleeve 21 and the shielding sleeve 22, there are sealing inner pads 24 installed. By installing the sealing inner pads 24 and the protective inner pads 25 inside the sealing and limiting mechanism 2, the sealing and stable effect during the overall installation of the sealing and limiting mechanism 2 is improved, thereby improving the overall use resistance of the protective outer sleeve 1.

[0032] In the above solutions, there is also a problem that when in use, it is often taken out and stored, which is extremely likely to cause the cable to be bent, resulting in the need for frequent replacement. For example, Figure 4 As shown: In this solution, a filling cushion layer 111 is installed on the inner wall of the stabilizing sleeve 11, and an elastic cushion layer 121 is installed on the inner wall of the bending-resistant sleeve 12. By installing the filling cushion layer 111 inside the stabilizing sleeve 11 and the elastic cushion layer 121 inside the bending-resistant sleeve 12, the bending resistance effect during overall use is improved. When deformed by impact, it can return to normal. The material of the filling cushion layer 111 is polyurethane high-resilience sponge, and the material of the elastic cushion layer 121 is gel. By installing the filling cushion layer 111 inside the stabilizing sleeve 11 and the elastic cushion layer 121 inside the bending-resistant sleeve 12, the bending resistance effect during overall use is improved. When deformed by impact, it can return to normal.

[0033] In the above solutions, there is also a problem of poor sealing connection effect during overall use, resulting in easy contamination by external water stains, dust particles, and posing a safety hazard. For example, Figure 1 、 Figure 2 and 4 As shown, in this solution, a braided sealing sleeve 15 is installed between multiple protective inner sleeves 13 and inside the bending-resistant sleeve 12. A reinforcing rib 16 is installed inside the braided sealing sleeve 15. The braided sealing sleeve 15 is used for separating and installing inside the protective outer sleeve 1. Aligning the reinforcing rib 16 and installing it inside the braided sealing sleeve 15 improves the overall use stability during use. A second compressive sleeve 3 is installed outside the protective outer sleeve 1 and between two sealing and limiting mechanisms 2. The installation quantity of the second compressive sleeve 3 can be increased or decreased according to use. At the same time, the distance between two adjacent second compressive sleeves 3 is adjustable. Equally spaced second anti-slip strips 31 are installed on the outside of the second compressive sleeve 3. The second anti-slip strips 31 are used to reduce the situation of accidental dropping due to excessive slipperiness during manual handling, and play a protective role to a certain extent.

[0034] Working principle:

[0035] For example Figures 1-4 As shown:

[0036] By installing a sealing inner pad 24 and a protective inner pad 25 inside the sealing and limiting mechanism 2, the sealing and stable effect during the overall installation of the sealing and limiting mechanism 2 is improved, thereby improving the use resistance of the overall protective outer sleeve 1;

[0037] The material of the filling cushion layer 111 is polyurethane high-resilience sponge, and the material of the elastic cushion layer 121 is gel. By installing the filling cushion layer 111 inside the stabilizing sleeve 11 and the elastic cushion layer 121 inside the bending-resistant sleeve 12, the bending resistance effect during overall use is improved. When deformed by impact, it can return to normal;

[0038] Reinforcing ribs 16 are installed inside the braided seal sleeve 15. The braided seal sleeve 15 is used for partitioning and installing the inside of the protective outer sleeve 1. Aligning the reinforcing ribs 16 and installing them inside the braided seal sleeve 15 improves the overall stability during use;

[0039] The installation quantity of the second compression sleeve 3 can be increased or decreased according to the use. At the same time, the distance between two adjacent second compression sleeves 3 is adjustable. Second anti-slip strips 31 are installed on the outer side of the second compression sleeve 3. The second anti-slip strips 31 are used to reduce the situation of accidental dropping caused by excessive slipperiness during manual handling, and play a protective role to a certain extent;

[0040] By using the protective outer sleeve 1, the stabilizing sleeve 11, the bend-resistant sleeve 12 and the second compression sleeve 3 in cooperation, the technical problem that the cable is easily bent when taken out and stored frequently during use is solved;

[0041] By providing the sealing limit mechanism 2, when in use, it is installed on the outer side of the protective outer sleeve 1 in the order of the first compression sleeve 21, the sealing inner pad 24, the shielding sleeve 22, the protective inner pad 25 and the first anti-slip strip 26, solving the technical problem of poor sealing connection effect during overall use, extending the overall service life of the equipment, and reducing potential safety hazards at the same time.
