Technical Field
[0001] The utility model relates to the technical field of high-strength pressure-resistant cables, in particular to a high-strength pressure-resistant cable with a protection tube. Background Art
[0002] Cables are usually rope-like cables made of several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and often twisted around a center. The entire outside is covered with a highly insulating covering layer. The cable has the characteristics of internal power supply and external insulation.
[0003] High-strength pressure-resistant cable refers to a cable with a high material quality that can resist and offset external pressure very well. It can protect the internal conductor or battery core from breaking or damage due to external pressure. The outermost layer of the high-strength pressure-resistant cable is an insulating rubber sheath, which is used to prevent the cable from leaking electricity.
[0004] However, in the prior art, the insulating sheath of the high-strength voltage-resistant cable is directly exposed to the external environment, and when it is hit or punctured by external sharp objects, the insulating layer and the internal structure of the high-strength voltage-resistant cable may be damaged. Utility Model Content

[0006] In order to solve the above technical problems, the technical solution of the utility model is:
[0007] A high-strength pressure-resistant cable with a protective tube comprises a cable body, the outer side of the cable body is sheathed with a protective tube, the protective tube comprises a first end splicing tube, an intermediate connecting tube and a second end splicing tube, the intermediate connecting tube has multiple parts and is located between the first end splicing tube and the second end splicing tube, the ends of the first end splicing tube, the intermediate connecting tube and the second end splicing tube are affixed and sealed by hot melt adhesive.
[0008] Preferably, the first end splicing tube, the middle connecting tube and the second end splicing tube all include an outer tube body, an inner tube body is inserted into the inner side of the outer tube body, the axes of the outer tube body and the inner tube body coincide, and the outer tube body and the inner tube body are made of rubber.
[0009] Preferably, a buffering and pressure-resistant inner tube is installed between the outer tube body and the inner tube body, a plurality of U-shaped protrusions are provided on the inner and outer sides of the buffering and pressure-resistant inner tube, and the buffering and pressure-resistant inner tube is made of rubber.
[0010] Preferably, sealing end pieces are detachably mounted on both ends of the outer tube body, and the sealing end pieces are bonded to the outer tube body by means of a sealant.
[0011] Preferably, a plurality of docking blocks distributed in a circular array around the axis of the outer tube are fixed to the inner side of the ends of the outer tube, and a connecting rod is clamped between the two docking blocks between the ends of two adjacent outer tubes.
[0012] Compared with the prior art, the utility model has the following advantages:
[0013] 1. Use the first end splicing tube, the middle connecting tube, and the second end splicing tube to form a protective tube and put it on the outside of the cable body to protect the cable body to prevent the insulation layer of the cable body from being pierced by sharp points. At the same time, the first end splicing tube, the middle connecting tube, and the second end splicing tube are all composed of an outer tube body, an inner tube body, and a buffer pressure-resistant inner tube. The buffer pressure-resistant inner tube supports the outer tube body and the inner tube body, so that there is enough space between the outer tube body and the inner tube body to resist and weaken the external pressure, thereby increasing the pressure resistance of the cable body.

[0019] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0020] like Figure 1As shown, a protective tube 2 is sleeved on the outer side of the cable body 1, and the protective tube 2 includes a first end splicing tube 3, an intermediate connecting tube 4 and a second end splicing tube 5. The intermediate connecting tube 4 has multiple splicing tubes and is located between the first end splicing tube 3 and the second end splicing tube 5. The ends of the first end splicing tube 3, the intermediate connecting tube 4 and the second end splicing tube 5 are adhered and sealed by hot melt adhesive. The protective tube 2 composed of the first end splicing tube 3, the intermediate connecting tube 4 and the second end splicing tube 5 is used to protect the outer side of the cable body 1 to prevent the insulation layer of the cable body 1 from being pierced by sharp objects.
[0021] As the preferred technical solution of this embodiment, Figures 2 to 4 As shown, the first end splicing tube 3, the middle connecting tube 4, and the second end splicing tube 5 all include an outer tube body 6, an inner tube body 7 is inserted into the inner side of the outer tube body 6, the axes of the outer tube body 6 and the inner tube body 7 coincide, and the outer tube body 6 and the inner tube body 7 are made of rubber, and a buffering pressure-resistant inner tube 8 is installed between the outer tube body 6 and the inner tube body 7, and a plurality of U-shaped protrusions are provided on the inner and outer sides of the buffering pressure-resistant inner tube 8, and the buffering pressure-resistant inner tube 8 is made of rubber. The buffering pressure-resistant inner tube 8 is used to support from the inside of the outer tube body 6 and the inner tube body 7, so as to increase the distance between the outer tube body 6 and the inner tube body 7, and improve the overall elastic buffering force of the first end splicing tube 3, the middle connecting tube 4, and the second end splicing tube 5.
[0022] Both ends of the outer tube body 6 are detachably mounted with sealing end pieces 9, which are bonded to the outer tube body 6 by sealant, and the outer tube body 6 is used to seal the end of the outer tube body 6 to ensure the sealing of the end of the protective tube 2 after assembly.
[0023] A plurality of docking blocks 11 distributed in a circular array around the axis are fixed to the inner side of the ends of the outer tube body 6, and a connecting rod 10 is clamped between the two docking blocks 11 between the ends of two adjacent outer tube bodies 6. The end of the connecting rod 10 is clamped between the docking block 11 and the outer tube body 6 to connect and fix the two adjacent outer tube bodies 6, thereby increasing the connection strength after the first end splicing tube 3, the middle connecting tube 4, and the second end splicing tube 5 are docked.
[0024] Working principle: First, apply adhesive to the inner walls of the outer tube body 6 and the inner tube body 7, then put the buffer pressure-resistant inner tube 8 on the outside of the inner tube body 7 and press it tightly, then insert the inner tube body 7 and the buffer pressure-resistant inner tube 8 into the outer tube body 6, and complete the assembly of the first end splicing tube 3, the middle connecting tube 4 and the second end splicing tube 5. After the first end splicing tube 3, the middle connecting tube 4 and the second end splicing tube 5 are assembled, use the first end splicing tube 3, the middle connecting tube 4 and the second end splicing tube 5 to assemble to form a protective tube 2. At this time, plug one end of the cable body 1 into a docking block 11 of an outer tube body 6. On the inside, dock the other outer tube body 6 with the outer tube body 6 of the installation docking block 11, so that the other end of the connecting rod 10 is inserted into the inner side of the docking block 11 at the end of the other outer tube body 6, and then use hot melt adhesive to seal and bond the ends of the two adjacent outer tube bodies 6. After the first end splicing tube 3, the middle connecting tube 4, and the second end splicing tube 5 form a protective tube 2, use the sealing end piece 9 to seal the end of the protective tube 2, and finally insert the cable body 1 into the protective tube 2.
