[0010] Preferably, the orifices at both ends of the installation pipe are threaded structures, and the threaded sleeve is adapted to the threaded cavities provided at the orifices at both ends of the installation pipe. The threaded sleeve is detachably threadedly connected to the installation pipe.

[0011] Preferably, the limiting block is an L-shaped structure. The engaging block provided at the port of the limiting block is adapted to the positioning cavity provided in the arc-shaped groove and the limiting groove, and is fitted and slidably connected.

[0012] Preferably, a heat-resistant pipe is further provided inside the installation pipe. The size of the heat-resistant pipe is the same as the inner diameter of the installation pipe, and the heat-resistant pipe is fitted into the installation pipe.

The connection component 200 includes a threaded sleeve 201. One end of the threaded sleeve 201 is further provided with a combination component 300. The combination component 300 includes a connection sleeve 301. A threaded ring 302 is arranged in the inner cavity of the connection sleeve 301. And a limiting groove 305 is also arranged on the connection sleeve 301. The connection sleeve 301 is also provided with a matching clamping sleeve 306. Limiting blocks 303 are arranged on both the connection sleeve 301 and the clamping sleeve 306. A clamping block 304 is arranged at the end of the limiting block 303. An arc-shaped groove 307 is also arranged on the clamping sleeve 306. A threaded ring 302 is also arranged in the clamping sleeve 306. The installation pipe 100 is rotationally combined and connected through the connection sleeve 301 and the clamping sleeve 306. During actual use, the staff sleeved the threaded sleeve 201 on the orifices at both ends of the installation pipe 100, and then threadedly connected the connection sleeve 301 with the threaded sleeve 201 at one end of the installation pipe 100. Similarly, the clamping sleeve 306 is installed at the end of the installation pipe 100. At this time, by aligning the clamping sleeve 306 with the connection sleeve 301 to make them tightly abut, and then rotating the clamping sleeve 306 until the clamping block 304 arranged in the limiting block 303 rotates and clamps into the cavity formed by the limiting groove 305 arranged on the connection sleeve 301 and the arc-shaped groove 307 arranged on the clamping sleeve 306, so as to realize the fixation of the connection sleeve 301 and the clamping sleeve 306. Through the fixation of the two, the combined installation of two groups of installation pipes 100 is further realized.

[0027] By the cooperative use of a plurality of parts in the connection component 200 and the combination component 300 provided, the rapid combination of a plurality of installation pipes 100 can be realized. During actual use, the combination and fixation of the installation pipes 100 can be realized by rotating the connection sleeve 301 and the clamping sleeve 306. Compared with the flange connection that requires aligning a plurality of bolt holes and tightening bolts one by one, the method using the connection sleeve 301 and the clamping sleeve 306 is usually designed for quick clamping, which simplifies the installation steps and greatly reduces the installation time.

[0028] Second Embodiment:

[0029] As Figures 3-4 shown, a sealing ring 309 is further arranged at the orifice of the clamping sleeve 306. The sealing ring 309 is fitted into the groove arranged on the clamping sleeve 306. During actual use, by aligning the clamping sleeve 306 with the connection sleeve 301 to make them tightly abut, and then rotating the clamping sleeve 306, when the two are connected, the tight abutment of the two is realized through the sealing ring 309 arranged on the clamping sleeve 306.

[0030] By using the engaging sleeve 306 and the sealing ring 309 in combination, the sealing performance inside the installation pipe 100 can be ensured. During long-term use, some dust may accumulate inside the vehicle, and the conductive particles contained in the dust may damage the insulation layer of the wire harness, thereby reducing its insulation performance and increasing the risk of short circuits. By ensuring a tight seal at the connection, this can be prevented from occurring.

[0031] Third Embodiment:

[0032] As Figures 1-2 shown, the two ends of the installation pipe 100 have a threaded structure, and the threaded sleeve 201 is adapted to the threaded cavities provided at the two ends of the installation pipe 100. The threaded sleeve 201 is detachably threadedly connected to the installation pipe 100. Since the two ends of the installation pipe 100 have a threaded structure, during actual installation, align the threaded sleeve 201 with the two ends of the installation pipe 100, and by rotating the threaded sleeve 201, the threaded sleeve 201 can be sleeved on the installation pipe 100.

[0033] By providing a threaded structure at the two ends of the installation pipe 100, the detachable installation of the threaded sleeve 201 can be achieved. Through the detachable installation of the threaded sleeve 201, the installation and disassembly of the combined component 300 can be further realized. By removing the threaded sleeve 201, the assembly and disassembly of the pipeline system become simple, facilitating daily maintenance and repair work.

[0034] Fourth Embodiment:

[0035] As Figures 2-3 shown, the limiting block 303 has an L-shaped structure. The engaging block 304 provided at the port of the limiting block 303 is adapted to the positioning cavity formed by the arc-shaped groove 307 and the limiting groove 305 provided, and is in an embedded and sliding connection. During actual use, by rotating the engaging sleeve 306 until the engaging block 304 provided in the limiting block 303 rotates and engages into the positioning cavity formed by the limiting groove 305 provided in the connecting sleeve 301 and the arc-shaped groove 307 provided in the engaging sleeve 306, the fixation of the connecting sleeve 301 and the engaging sleeve 306 can be achieved. Through the fixation of the two, the combined installation of the two installation pipes 100 can be further realized.

[0036] Through the design of the limiting block 303 and the engaging block 304, additional stability and strength are provided during rotation. When the engaging block 304 rotates into the limiting groove 305 of the connecting sleeve 301, it provides the ability to resist torsion and tension for the entire connection.

A moisture-proof pipe 500 is further provided inside the installation pipe 100. The moisture-proof pipe 500 is fitted into the inner circle of the heat-resistant pipe 400. During actual use, by providing the heat-resistant pipe 400 and the moisture-proof pipe 500 inside the installation pipe 100, the burning speed of the wire harness can be slowed down in case of a fire. At the same time, the moisture-proof pipe 500 can prevent water vapor from entering the wire harness, reduce short circuits or corrosion caused by moisture, and reduce the occurrence probability of electrical faults, thereby improving the safety of the vehicle.

[0039] Working principle: During actual use, the staff sleeved the threaded sleeve 201 at both ends of the installation pipe 100, and then threadedly connected the connecting sleeve 301 to the threaded sleeve 201 at one end of the installation pipe 100. Similarly, the clamping sleeve 306 was installed at the end of the installation pipe 100. At this time, by aligning the clamping sleeve 306 with the connecting sleeve 301 to make them tightly abut, and then rotating the clamping sleeve 306 until the clamping block 304 provided in the limiting block 303 of the two rotated and clamped into the cavity formed by the limiting groove 305 provided in the connecting sleeve 301 and the arc-shaped groove 307 provided in the clamping sleeve 306, the fixing of the connecting sleeve 301 and the clamping sleeve 306 was realized. Through the fixing of the two, the combined installation of the two installation pipes 100 was further realized.
