Detailed Description

The utility model will now be further described with reference to the accompanying drawings.

Example one

As shown in fig. 1 to 7, an easily installable corrugated pipe includes an inner corrugated pipe 2 and an outer corrugated pipe 1.

An inner opening 23 is formed in the inner corrugated pipe 2, the inner opening 23 is arranged along the axis and is communicated with the inside of the inner corrugated pipe 2, and the width of the inner opening 23 is not larger than the radius of the inner corrugated pipe 2; typically, the width of the inner opening 23 is less than the diameter of the wire, preventing the wire from sliding out of the inner bellows 2.

An outer opening 12 is formed in the outer corrugated pipe 1, the outer opening 12 is arranged along the axis and is communicated with the interior of the outer corrugated pipe 1, the width of the outer opening 12 is larger than that of the inner opening 23, and the width of the outer opening 12 is smaller than the radius of the outer corrugated pipe 1; the outer opening 12 is conveniently inserted into the inner corrugated pipe 2, the opening of the inner corrugated pipe 2 is small to prevent the lead from falling off, and the lead and the inner corrugated pipe 2 are conveniently pressed into the outer corrugated pipe 1 together through the outer opening 12.

The inner corrugated pipe 2 is sleeved in the outer corrugated pipe 1, and an outer convex ring 21 of the inner corrugated pipe 2 is clamped in an inner groove 11 of the outer corrugated pipe 1; the convex ring 21 and the inner groove 11 can prevent the corrugated pipe from axially moving, and stability and reliability are improved.

In some embodiments, the inner opening 23 and the outer opening 12 may also be arranged along a spiral.

When the lead is overhauled, the inner corrugated pipe 2 is pulled, so that the inner corrugated pipe 2 is pulled out from the outer opening 12 of the outer corrugated pipe 1, and then the lead is pulled out from the inner opening 23 of the inner corrugated pipe 2; when the maintenance is finished, the conducting wire is inserted into the inner corrugated pipe 2 again through the inner opening 23, and then the inner corrugated pipe 2 is inserted into the outer corrugated pipe 1 through the outer opening 12, so that the maintenance is very convenient.

When the wire is sleeved, after the wire is connected, the inner corrugated pipe 2 and the outer corrugated pipe 1 are cut according to the length, the inner corrugated pipe 2 is inserted into the wire through the inner opening 23, then the inner corrugated pipe 2 is inserted into the outer corrugated pipe 1 through the outer opening 12, and the installation is very convenient.

Normally, it is necessary to offset the inner opening 23 from the outer opening 12 to prevent the lead wires from slipping out of the outer bellows 1 through the outer opening 12 and the inner opening 23 when the inner opening 23 and the outer opening 12 are on the same side, which would cause the bellows to be out of service. Meanwhile, the inner opening 23 and the outer opening 12 are arranged in a staggered mode, so that water or dust can be prevented from entering the inner corrugated pipe 2, and a lead is protected.

Example two

On the basis of the first embodiment, the inner corrugated tube 2 is provided with the positioning protrusion 22, the positioning protrusion 22 is arranged on the outer convex ring 21 of the inner corrugated tube 2, and the positioning protrusion 22 is inserted into the outer opening 12. The positioning protrusion 22 can prevent the inner corrugated pipe 2 from rotating, so that the inner opening 23 is always staggered with the outer opening 12, and the assembly and positioning are convenient.

In some embodiments, the inner opening 23 is opposite to the positioning protrusion 22, i.e. the inner opening 23 is offset from the outer opening 12 by an angle of 180 °, and the distance between the inner opening 23 and the outer opening 12 is the largest, and the wire can be conveniently pulled out.

EXAMPLE III

On the basis of any one of the above embodiments, the inner corrugated pipe 2 and the outer corrugated pipe 1 are both reducing pipes. The reducing pipe is convenient to install, and particularly, the corrugated pipe is convenient to fix at the joint of the reducing pipe and the equipment through different diameters.

The technical principle of the present invention is described above in connection with specific embodiments. The description is made for the purpose of illustrating the principles of the utility model and should not be construed in any way as limiting the scope of the utility model. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without inventive step, which shall fall within the scope of the appended claims.
