Description

Technical Field

[0001] This utility model relates to the field of shock-absorbing pipe technology, and in particular to a shock-absorbing flexible hose. Background Technology

[0002] Vibration-damping hoses are flexible connection components widely used in industrial fields. They are mainly used to transport liquids, gases, and other media, and to compensate for and dampen vibrations under conditions of vibration, displacement, or thermal expansion and contraction. A typical structure usually includes a bellows, a flared connector, and a wire mesh sleeve. The bellows provides flexibility and extensibility, the flared connector connects to external piping systems, and the wire mesh sleeve enhances pressure resistance, limits excessive deformation, and protects the bellows.

[0003] In existing manufacturing processes for vibration-damping hoses, a multi-step welding method is commonly used to achieve reliable connections between the various components. The specific process generally involves: first, welding one end of the corrugated pipe to the flared connector; then, placing a wire mesh sleeve over the corrugated pipe; next, using auxiliary rings or other components to cover or attach the end of the wire mesh sleeve; finally, another welding operation is required to secure the auxiliary ring, wire mesh sleeve, and corrugated pipe or flared connector together. This step-by-step welding process is not only cumbersome and inefficient, but multiple welding operations can also lead to overlapping heat-affected zones, affecting material properties and increasing the risk of deformation or leakage. Furthermore, the high positioning accuracy required during welding, coupled with operational inconvenience, increases manufacturing costs and the difficulty of quality control. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a shock-absorbing flexible hose with a reasonable structure, convenient assembly, and robust connection. Through structural optimization, this shock-absorbing flexible hose allows for a single-step welding process between the corrugated pipe, wire mesh sleeve, auxiliary ring, and flared connector, significantly simplifying the manufacturing process.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a shock-absorbing hose, comprising a corrugated pipe, a flared connector, a wire mesh sleeve, and an auxiliary ring; The corrugated pipe is sleeved with the flared pipe, the wire mesh sleeve is sleeved outside the corrugated pipe, and the auxiliary ring is sleeved at the end of the wire mesh sleeve. The shock-absorbing hose is provided with a welding part, and the corrugated pipe, wire mesh sleeve and auxiliary ring are welded together with the outer wall of the flared pipe at the end near the flared pipe side to form the welding part.

[0006] In the above scheme, preferably, the welded part is formed by argon arc welding.

[0007] In the above scheme, preferably, the corrugated pipe is provided with an extension pipe, and the extension pipe is slidably sleeved with the flared pipe.

[0008] In the above scheme, preferably, the extension tube and the corrugated tube are integrally formed.

[0009] In the above scheme, preferably, the flared connector includes a sleeve connector, which is sleeved on the inner wall of the extension pipe, and a stop portion that cooperates with the sleeve connector is formed between the extension pipe and the corrugated pipe.

[0010] In the above scheme, preferably, the wire mesh sleeve is fitted over the corrugated pipe, and its end face near the flared pipe end face coincides with or nearly coincides with the end face of the extension pipe.

[0011] In the above scheme, preferably, the auxiliary ring is a hollow sleeve, which is sleeved on the outer wall of the wire mesh sleeve, and its end face near the flared pipe end face coincides with or nearly coincides with the end face of the extension pipe and the end face of the wire mesh sleeve.

[0012] In the above scheme, preferably, the welding part is formed by integrally welding the outer wall of the sleeve pipe with the extension pipe, the wire mesh sleeve and the end face of the auxiliary ring.

[0013] In the above scheme, preferably, one end of the auxiliary ring is fixed to the welding part, and the other end extends to one end of the corrugated pipe to achieve guiding and covering of the wire mesh sleeve.

[0014] In the above scheme, preferably, the flared connector is provided at both ends of the corrugated pipe, the wire mesh sleeve is provided to cover the outer wall of both ends of the corrugated pipe, and the auxiliary ring is symmetrically provided at both ends of the wire mesh sleeve and welded and fixed to the corresponding flared connector and extension pipe to form a welded part.

[0015] The beneficial effects of this utility model are: through structural optimization, this utility model integrates the ends of the corrugated pipe, wire mesh sleeve and auxiliary ring with the outer wall of the flared pipe in the same annular area, realizing the one-time welding of multiple parts, which greatly simplifies the assembly and welding process and significantly improves production efficiency. Meanwhile, single-stage welding reduces the impact of multiple heat inputs on material properties, lowers the risk of component deformation and potential leaks, and improves product consistency and reliability. Furthermore, this structure reduces the stringent requirements for assembly precision and operational complexity, thereby effectively controlling production costs. The extended design of the auxiliary ring also strengthens the coverage and constraint of the wire mesh sleeve ends, further ensuring the long-term stability of the structure.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See below Figures 1-2 .

[0019] A type of shock-absorbing flexible hose mainly consists of a corrugated pipe 1, a flared connector 2, a wire mesh sleeve 3, and an auxiliary ring 4. Both ends of the corrugated pipe 1 are formed with an extension pipe 101 whose diameter is matched with that of the flared connector 2. The extension pipe 101 and the corrugated pipe 1 are integrally formed, that is, during the forming process of the corrugated pipe 1, a straight pipe is left at both ends for connection.

[0020] The flared connector 2 includes a connection port for connecting to an external pipeline and a sleeve 201 for connecting to the bellows 1. During assembly, the sleeve 201 is inserted into the inner hole of the extension pipe 101 until it is limited by the annular stop 102 formed at the junction of the extension pipe 101 and the bellows 1. Figure 2 As shown, at this time, the end face of the extension tube 101 is located at the outer wall of the straight tube of the sleeve tube 201; in this embodiment, the sliding fit between the sleeve tube 201 and the extension tube 101 is preferably a clearance fit or a transition fit, so that the sleeve tube 201 can be smoothly guided into the extension tube 101 and form a near-concentric positioning.

[0021] The wire mesh sleeve 3 is fitted over the corrugated pipe 1, with its end faces machined to be substantially flush with the end faces of the extension pipes 101 at both ends. Two auxiliary rings 4 are provided outside the wire mesh sleeve 3 at both ends, respectively fitted onto the outer sides of the wire mesh sleeve 3. One end face of each auxiliary ring 4 is also flush or nearly flush with the end face of the corresponding extension pipe 101 and the end face of the wire mesh sleeve 3. At this time, the inner wall of the auxiliary ring 4 is tightly attached to the outer wall of the wire mesh sleeve 3, while its end wall is located on the outer wall of the sleeve pipe 201.

[0022] After completing the above alignment and assembly, a welding process is performed using an argon arc welding machine. Circumferential welding is carried out on the annular area enclosed by the outer wall of the sleeve 201, the flush-aligned end face of the extension tube 101, the end face of the wire mesh sleeve 3, and the end face of the auxiliary ring 4. The weld pool fuses the materials at the ends of the four metal components together, and after cooling, forms a strong and sealed annular weld 5, as shown below. Figure 2 As shown in the diagram, the welding section 5 completes the fixed connection between the corrugated pipe 1, the wire mesh sleeve 3, the auxiliary ring 4, and the flared pipe 2 in one operation.

[0023] After welding, except for the welded and fixed end, the auxiliary ring 4 extends towards the middle of the corrugated pipe 1, like a sleeve wrapping around the end edge of the wire mesh sleeve 3, providing good protection and restraint.

[0024] In this embodiment, the corrugated pipe 1, wire mesh sleeve 3, auxiliary ring 4 and flared pipe 2 are all made of metal, thereby enabling one-time welding of argon arc welding.

[0025] This invention, by setting up an extension tube and aligned end face structure, concentrates the welding points that are scattered in multiple locations in traditional processes into a ring-shaped area, achieving one-time welding of multiple components. This greatly simplifies the assembly and welding process, improves production efficiency, reduces the number of heat inputs, lowers the impact on material properties and the risk of deformation, and enhances product consistency and reliability; it also reduces the skill requirements for workers and production costs.

[0026] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
