Problems solved by technology

[0004] The applicant has previously applied for an invention patent on this issue, the application number is 201710095636.2, which solves the problem of replacing the rubber tube with a metal tube, but the applicant found that this structure has the following disadvantages in practical application: the corrugation in the patent The pipe includes a straight pipe section and a corrugated pipe section. Since it is necessary to ensure that the outer diameter of the straight pipe section is the same as the maximum diameter of the corrugated pipe section, in practical applications, the straight pipe section and the corrugated pipe section are processed separately and then welded together to form an integration. Risk of breaking due to vibration

Embodiment 1

[0038] like Figure 1-Figure 4 As shown, the new all-metal air-conditioning hose of the present invention includes a metal bellows 1, a metal liner 2, a metal straight pipe sleeve 3, a metal fastening sleeve 4 and a metal wire braid 5;

[0039] The metal straight pipe sleeve 3 is step-shaped, including left pipe I6 and right pipe I7, the diameter of left pipe I is larger than that of right pipe I, right pipe I is inserted into the metal bellows for at least two complete wave pitch lengths, and the outer diameter of right pipe I is Matching with the minimum inner diameter of the metal bellows, the right pipe I has a supporting effect on the bottom of the metal bellows, thus effectively avoiding the damage of the driving vibration to the weld, which is an anti-vibration design. The port at the left end of the metal bellows is welded and fixed to the right end of the left pipe I. The outer surface of the metal bellows is covered and filled with a rubber layer 8. The outer diamete...

Embodiment 2

[0044] This embodiment is a further improvement on Embodiment 1. In this embodiment, the positions and connections of the pipes remain unchanged. The difference is that, as Image 6 As shown, several annular grooves 14 are also arranged on the left pipe I, such as Figure 7As shown, the right pipe II is provided with an anti-seize annular groove 15, and the anti-seize annular groove is located directly below the upper annular groove of the left pipe I, and its width covers all the annular grooves on the left pipe I. The right pipe II and the left pipe Ⅰ Both radial and axial directions are precision clearance fits. The metal fastening sleeve and the metal straight pipe sleeve are connected by crimping, and the crimping position corresponds to the position of the annular groove on the left pipe I. In order to prevent deformation during crimping, the wall thickness of the left pipe I is greater than that of the right pipe I in this embodiment. When the metal fastening sleeve i...

Embodiment 3

[0048] This embodiment is simplified from Embodiment 1, such as Figure 9 As shown, in this embodiment, the metal liner and the metal straight pipe are combined into one to form a bridge-shaped metal liner 16. The bridge-shaped metal liner includes a left pipe IV17, a middle pipe 18 and a right pipe IV19. The right tube IV is equivalent to the right tube I in Example 1, and the right tube IV is inserted into the metal bellows for at least two complete wave lengths, the outer diameter of the right tube IV matches the minimum inner diameter of the metal bellows, and the left end port of the metal bellows It is welded and fixed with the right end face of the middle pipe, the outer diameter of the middle pipe is the same as the outer diameter of the metal bellows covered with rubber layer, the left pipe IV is equivalent to the left pipe II in embodiment 1, and the outer diameter of the left pipe IV is the same as The inner diameter of the left pipe III matches, and the metal faste...

Abstract

The invention relates to the field of hose and rigid structure connection and discloses a novel full-metal air conditioner hose which comprises a metal corrugated pipe, a metal liner tube, a metal straight pipe sleeve, a metal fastening sleeve and a metal wire weaving layer. The metal straight pipe sleeve is step-shaped and comprises a left pipe I and a right pipe I; the left pipe I is inserted into at least two intact corrugations of the metal corrugated pipe; the metal liner tube is step-shaped and comprises a left pipe II and a right pipe II, and the right pipe II is inserted into the leftpipe I; the metal fastening sleeve is step-like and comprises a left pipe III and a right pipe III, the right pipe III is sleeved on the left pipe I and the left pipe III is sleeved on the left pipe II; and the metal fastening sleeve, the metal liner tube and the metal straight pipe sleeve are connected in a withholding mode. The full-metal air conditioner hose replaces a rubber air conditioner hose, so that defects of the rubber hose are avoided. By increasing anti-vibrating and anti-twisting designs, the problem of cracking or twisting damage at the welded part as a result of travelling vibration can be solved effectively.

Description

technical field [0001] The invention relates to the field of connection between hoses and rigid structures, in particular to a novel all-metal air-conditioning hose. Background technique [0002] At present, the automobile air-conditioning hose is an air-conditioning hose assembly in which a metal hard pipe and a rubber air-conditioning hose are crimped together. The metal tube part is usually an aluminum tube, and the hose is usually a rubber tube. The combined air-conditioning hose assembly has good flexibility, good shock absorption, and is easy to install. [0003] However, automobiles have entered the new energy era, and their air-conditioning systems have begun to use new types of refrigerants, which work under high temperature and high pressure, so the original rubber air-conditioning hoses are completely ineffective under this working condition. Even the rubber air-conditioning hoses that are currently in use will become secondary pollution sources and be eliminated...
