[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 The utility model provides a technical solution: a detachable MPP tube, comprising a cable protection tube 1 and a corrugated protective hose 2, wherein two cable protection tubes 1 are provided and respectively assembled at the two ends of the corrugated protective hose 2, and a limiting frame 3 is installed on the periphery of one end of the two cable protection tubes 1, and a plurality of metal shaped hoses 4 are connected between the two limiting frames 3, and a first connecting disk 6 and a second connecting disk 7 are respectively installed on the ends of the two cable protection tubes 1 away from the corrugated protective tube 2; a plurality of connecting jacks 8 distributed in a circular array are provided on the first connecting disk 6, and a plurality of interlocking teeth 9 distributed at equal distances are fixedly connected to the inner walls of the plurality of connecting jacks 8 close to the center of the cable protection tube 1, and a plurality of connecting plugs 11 are installed on the outer side of the second connecting disk 7, and the plurality of connecting plugs 11 correspond to the plurality of connecting jacks 8 one by one, and the inner sides of the plurality of connecting plugs 11 are provided with interlocking tooth grooves 12 adapted to the interlocking teeth 9.

[0022] Based on the above-mentioned structural setting, the detachable MPP tube is composed of a cable protection tube 1 and a corrugated protective hose 2, wherein both ends of the corrugated protective hose 2 are connected to the ports of the cable protection tube 1, and the cable protection tube 1 is a pipe using modified polypropylene as the main raw material, and the corrugated protective hose 2 has certain shrinkage, bending and twisting deformation characteristics. During use, the cable protection tube 1 and the corrugated protective hose 2 can effectively achieve the protection function. Specifically, during use, by inserting the connecting plug 11 into the interior of the connecting hole 8, the interlocking teeth 9 and the interlocking tooth grooves 12 engage with each other during the insertion process, thereby expanding the contact surface and increasing the tightness between the connecting plug 11 and the connecting hole 8. When disassembly is required, the connecting plug 11 is pulled out from the interior of the connecting hole 8 to achieve disassembly. During the connection process of the cable protection tube 1, the corrugated protective hose 2 is contracted. , bending and twisting deformation processing, the position and angle of the first connecting plate 6 can be changed during use to facilitate connection and use. During the adjustment process of the corrugated protective hose 2, the metal shaping hose 4 between the limiting frames 3 is used to limit the adjusted corrugated protective hose 2 to avoid the automatic deformation of the corrugated protective hose 2 after the adjustment deformation. The detachable MPP tube is installed with a connecting plug 11 and inserted into the connecting jack 8. A snap-on method is used to achieve rapid assembly and disassembly. No welding or hot-melt equipment is required, which reduces the difficulty and cost of installation. The corrugated protective hose 2 can shrink, bend and twist, and the first connecting plate 6 can be adjusted according to actual use conditions to facilitate rapid docking. The metal shaping hose 4 between the limiting frames 3 is used to limit the adjusted corrugated protective hose 2 to increase the strength between the device structures.

[0023] Furthermore, a boss 10 is installed around the front end of the first connection plate 6 on the periphery of the connection socket 8, and a barb buckle 13 adapted to the boss 10 is connected to the front end of the connection plug 11. The barb buckle 13 is made of elastic material and can be slightly bent and deformed during the process of force extrusion. After the connection plug 11 is inserted into the connection socket 8, the barb buckle 13 is driven by the connection plug 11 to extend from the inside of the connection socket 8 and is clamped on the boss 10. After clamping, the barb buckle 13 hooks the boss 10 to prevent the connection plug 11 from falling off from the inside of the connection socket 8, thereby achieving a reinforcement effect. When it needs to be removed, the barb buckle 13 is squeezed and deformed to separate the barb buckle 13 from the boss 10 to achieve disassembly.

[0024] Furthermore, a special-shaped through hole is provided inside the limit frame 3, and a limit slot 5 matching the special-shaped through hole is provided outside the cable protection tube 1. The minimum radius between the inner wall and the axis of the special-shaped through hole is larger than the radius of the wiring hole inside the cable protection tube 1, and smaller than the outer radius of the cable protection tube 1. When the limit frame 3 is clamped inside the limit slot 5, it can effectively prevent the limit frame 3 from rotating outside the cable protection tube 1 during use, making the structure more stable.

[0025] Furthermore, a bevel notch 15 is provided at the end of the connecting jack 8 away from the cable protection tube 1. The minimum diameter of the bevel notch 15 is the same as the diameter of the connecting jack 8. When in use, the bevel notch 15 can be used to provide auxiliary guidance before the connecting plug 11 is inserted into the connecting jack 8, so that the user can quickly connect and improve work efficiency.

[0026] Furthermore, the cable protection tube 1 and the corrugated protective hose 2 are provided with wiring holes, and the first connection plate 6 and the second connection plate 7 are provided with a plurality of bolt holes 14 around the cable protection tube 1 as the axis. The diameter of the wiring hole is the same as the diameter of the first connection plate 6 and the second connection plate 7. After the first connection plate 6 and the second connection plate 7 are connected by bolts passing through the bolt holes 14 on the first connection plate 6 and the second connection plate 7, the first connection plate 6 and the second connection plate 7 can be connected, so that the connection between the cable protection tubes 1 is more stable.
