DETAILED DESCRIPTION

[0022] The utility model will be further described below in combination with examples.

[0025] External pipeline is screwed into the threaded sleeve 9 in the inboard of two connecting pipes 2 respectively, it will extrude soft pad 11 and extrusion assembly 12 to the outboard, so that extrusion spring sheet 1202 is deformed, and rebound is generated, and soft pad 11 is pushed to clamp pipe, ensure the airtightness of connecting pipe 2.

[0026] As the pipeline gradually penetrates, it will extrude the soft pad 11 inward, and this extrusion process is further transmitted to the built-in extrusion assembly 12. The extrusion spring 1202 can deform laterally when subjected to external force due to its high elastic material and structural design. This deformation is not only an effective response to external force, but also a process of storing energy in the extrusion spring 1202. They will generate strong rebound force, which will extrude the pipeline through the soft pad 11 in the opposite direction. This reverse extrusion force ensures that the soft pad 11 and the pipeline are tightly attached, not only enhancing the stability of the connection, but also greatly improving the sealing performance between the pipeline and the connecting pipe 2.

[0027] Please refer to Figures 1-4 , the oil pipe body 1 includes an outer tube 3 on the outside, the inner side of the outer tube 3 is fixedly connected with the shockproof layer 4, the shockproof layer 4 includes the outer connection layer 401 on the inside and the outside, the inside of the two outer connection layers 401 is fixedly connected with a plurality of shockproof strips 402, the inside of the shockproof layer 4 is fixedly connected with the anti-stretching layer 5, the anti-stretching layer 5 includes the connection layer 501 on the inside and the outside, the inside of the two connection layers 501 is fixedly connected with a plurality of anti-stretching strips 502, the inside of the anti-stretching layer 5 is fixedly connected with the inner tube 6, the two sides of the outer tube 3 are fixedly connected with the extension pipe 8, the outer connection layer 401 on the outside is fixedly connected with the inside of the outer tube 3, the inner connection layer 401 on the inside is fixedly connected with the connection layer 501 on the outside, the connection layer 501 on the inside is fixedly connected with the outside of the inner tube 6, the shockproof strips 402 are annularly distributed in the inside of the two outer connection layers 401, which are transversely twisted, the anti-stretching strips 502 are annularly distributed in the inside of the two connection layers 501, which are longitudinally twisted, the inside of the inner tube 6 is coated with the anticorrosive coating 7, and the diameter of the inside of the extension pipe 8 is consistent with the diameter of the inside of the anticorrosive coating 7.

[0028] When the pipeline body 1 transports fluid, the shockproof strips 402 can absorb and disperse energy when external vibration extrusion occurs, thereby effectively reducing the influence on the pipeline body 1, and the anti-stretching strips 502 can resist stretching deformation when external stretching occurs, thereby maintaining the stability and shape integrity of the pipeline body 1.

[0029] The anti-shock strip 402 can be deformed laterally when being pressed due to its unique lateral twist shape and elastic material selection, which not only provides the necessary space for the pressing, but more importantly, absorbs the kinetic energy generated by the pressing like a spring, effectively buffering the external impact force, thereby protecting the structural integrity of the oil pipe body 1. The deformed anti-shock strip 402 also has a rebound effect, which not only helps to restore the device to its original state, but also can offset the subsequent pressing effect to some extent, ensuring the stability of the device during the pressing process. The anti-stretching strip 502 is designed in a longitudinal twist shape and can be deformed during stretching, but this deformation is not simply elongation, but is accompanied by rearrangement of the internal structure of the material and energy storage. This energy storage process enables the anti-stretching strip 502 to generate strong rebound force before being stretched to the limit, thereby avoiding the risk of breakage due to excessive stretching. This design not only improves the tensile strength of the device, but also ensures its stability and durability under long-term tensile stress.

[0030] The working principle and use process of the utility model are as follows: the external pipeline is respectively screwed into the threaded sleeve 9 inside the two connecting pipes 2, which will extrude the soft pad 11 and the extrusion assembly 12 to the outside, make the extrusion spring 1202 deform and rebound, push the soft pad 11 to clamp the pipeline, ensure the sealing of the connecting pipe 2, transport fluid through the oil pipe body 1, when external vibration and extrusion occur, the anti-shock strip 402 can absorb and disperse energy, thereby effectively reducing the influence on the oil pipe body 1, when external stretching occurs, the anti-stretching strip 502 can resist stretching deformation, maintain the stability and shape integrity of the oil pipe body 1.

[0031] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles of the utility model, the scope of the utility model is defined by the appended claims and their equivalents.
