the number of the nuts 1 is two, the two nuts 1 are respectively installed at two ends of the pipe body assembly 3, the nuts 1 correspond to the pipe body assembly 3 one by one, and the nuts 1 can freely rotate relative to the pipe body assembly 3; the seal ring 2 is disposed inside the nut 1.

Thus, the spring 34 is arranged in the hose body 33 to support the pipe wall of the hose body 33, and when the hose body 33 is bent during installation, the pipe wall of the hose body 33 can keep a passage under the supporting effect of the spring 34, so that the problem that the conventional hose is crushed due to bending in the installation and use process can be well solved, the inside of the hose body 33 can be kept smooth, and liquid/gas in the hose body 33 cannot be blocked. The core 32 can position both ends of the spring 34, so that the spring 34 can be fixed inside the hose body 33, and the spring 34 has better flexibility and can be bent freely along with the hose body 33; the steel sleeve 31 may be fixed to the end of the hose body 33 in cooperation with the core 32. The nut 1 is used for being connected with other parts, and the sealing ring 2 can enable the hose to be more tightly connected with other parts, so that leakage is prevented.

Preferably, a snap ring 321 is disposed on an outer wall of the core body 32, one end of the nut 1 is an open structure, the other end of the nut 1 is provided with a central hole 11, one end of the core body 32 passes through the central hole 11 and is inserted into an end portion of the hose body 33, and the snap ring 321 clamps the nut 1 to the end portion of the hose body 33; the side wall of the steel sleeve 31 is provided with an exhaust hole 311.

The overall structure of the structure is simpler and more compact, when assembling, the steel sleeve 31 is sleeved on the end part of the hose main body 33, then the core body 32 penetrates through the nut 1 and is inserted into the end part of the hose main body 33, finally the steel sleeve 31 is compressed through external equipment, so that the steel sleeve 31 deforms and dents, in the process of compressing the steel sleeve 31, air between the steel sleeve 31 and the hose main body 33 can be exhausted through the exhaust hole 311, the core body 32 is fixed on the end part of the hose main body 33, the core body 32 limits the nut 1 on the end part of the hose main body 33 through the snap ring 321, and the nut 1 can rotate relative to the core body 32 and the hose main body 33.

Preferably, one end of the core 32 is provided with a connecting section 322, and the end of the spring 34 is sleeved on the outer wall of the connecting section 322.

This arrangement positions the spring 34, prevents the spring 34 from sliding back and forth within the hose body 33, and secures the spring 34 within the hose body 33.

Preferably, one end of the nut 1 is an open structure, and the other end is provided with a central hole 11; the inner wall of one end of the steel sleeve 31 is tightly pressed on the outer wall of the end part of the hose main body 33, the middle part of the steel sleeve 31 is provided with a corrugated section 312, the other end of the steel sleeve 31 is provided with a convex ring 313, and the convex ring 313 limits the nut 1 on the steel sleeve 31.

Set up ripple section 312 on steel bushing 31 and can make two sections of hose all have better buckling deformation ability, its compliance is better, not only makes the hose can conveniently adjust its crooked angle and crooked direction when the installation like this to make the work progress simpler, ripple section 312 is difficult for appearing the condition of flattening moreover, thereby can avoid the inside water/gas of hose main part 33 well and blocked the problem.

Preferably, the other end of the core 32 is provided with a groove 323, the pipe body assembly 3 further includes a sealing ring 35, the sealing ring 35 is disposed in the groove 323, and an outer wall of the sealing ring 35 abuts against an inner wall of the steel sleeve 31.

This arrangement seals the gap between the core 32 and the steel sleeve 31, effectively preventing the liquid/gas in the hose from leaking out of the gap between the core 32 and the steel sleeve 31. The groove 323 can limit the sealing ring 35, and prevent the sealing ring 35 from sliding back and forth along the axial direction of the core body 32, thereby preventing the sealing ring 35 from being separated from the core body 32.

Preferably, the inner wall of the sealing ring 2 is provided with an annular groove 21 matched with the convex ring 313, and the convex ring 313 is clamped in the annular groove 21 to fix the sealing ring 2.
