A high flexibility corrugated connecting hose

Abstract

This application relates to a high-toughness corrugated connecting hose, comprising a corrugated tube body and multiple support rings. The support rings are fixed within the corrugated tube body. Each support ring has a channel extending through it along the length of the corrugated tube body. The diameter of the openings at both ends of the channel is smaller than the cross-sectional diameter of the channel. A tough guide post passes through the channel. Adjacent support rings are connected by the tough guide post. Each tough guide post includes a column body and two connecting portions located at both ends of the column body. The cross-sectional diameter of the connecting portions is larger than the cross-sectional diameter of the openings at both ends of the channel. By providing tough guide posts and multiple support rings connected by them, this application ensures that while the corrugated tube body is supported by the support rings, adjacent support rings can abut against each other, preventing damage to the corrugated tube body due to excessive compression. Furthermore, the connecting portions of the tough guide posts abut against the openings at both ends of the channel after the corrugated tube body is overstretched, further preventing damage to the corrugated tube body due to excessive stretching.

Description

Technical Field

[0001] This application relates to the field of corrugated pipe technology, and in particular to a high-toughness corrugated connecting hose. Background Technology

[0002] Corrugated hoses are a commonly used type of pipe, usually made of metal. Corrugated connecting pipes are widely used because their corrugated bodies have good flexibility and extensibility.

[0003] In practical applications, the corrugated pipe body is prone to deformation of the corrugated surface due to excessive stretching or compression, which leads to a decrease in the expansion and contraction performance of the corrugated pipe body or even damage to the corrugated pipe body. Therefore, there is an urgent need for a high-toughness corrugated hose to solve this problem. Utility Model Content

[0004] This application provides a high-toughness corrugated connecting hose.

[0005] The high-toughness corrugated connecting hose provided in this application adopts the following technical solution:

[0006] A high-toughness corrugated connecting hose includes a corrugated tube body and multiple support rings. The multiple support rings are fixed in the corrugated tube body. Each support ring has a channel extending through it along the length of the corrugated tube body. The diameter of the openings at both ends of the channel is smaller than the cross-sectional diameter of the channel. A tough guide post is inserted into the channel. Adjacent support rings are connected by the tough guide post. Each tough guide post includes a column body and two connecting portions located at both ends of the column body. The cross-sectional diameter of the connecting portions is larger than the cross-sectional diameter of the openings at both ends of the channel.

[0007] Preferably, the cross-sectional diameter of the outer periphery of the support ring is at least 70 times the cross-sectional diameter of the column.

[0008] Preferably, the number of channels is four, and the four channels are evenly arranged around the support ring. The number of the flexible guide posts corresponds to the number of channels, which is also four.

[0009] Preferably, the inner ring of the support ring has a recess that smoothly connects with the end of the bellows body.

[0010] Preferably, a plurality of mounting grooves are formed inside the corrugated pipe body;

[0011] The support ring is provided with multiple protrusions corresponding to the multiple mounting slots, and the multiple protrusions are fixed in the mounting slots one by one.

[0012] Preferably, the flexible guide post is a plastic guide post or a silicone guide post. In summary, this application includes at least one of the following beneficial technical effects:

[0013] 1. This application, by setting a flexible guide post and multiple support rings connected by the flexible guide post, ensures that when the bellows body is supported by the support rings, adjacent support rings can abut against each other when the bellows body is over-compressed, making the bellows body less prone to damage due to over-compression.

[0014] 2. By opening a channel on the support ring and inserting the flexible guide post inside the channel, the connection part of the flexible guide post abuts against the openings at both ends of the channel after the bellows body is overstretched, so that the bellows body is not easily damaged due to overstretching.

[0021] The present application will be further described in detail below with reference to the accompanying drawings.

[0022] This application provides a high-toughness corrugated connecting hose, such as Figures 1 to 5 As shown, it includes a bellows body 1 and multiple support rings 2.

[0023] like Figure 1 and Figure 2 As shown, both the corrugated pipe body 1 and the support ring 2 are made of metal. The corrugated pipe body 1 and the support ring 2 are fixed together by welding. Multiple mounting grooves 11 are evenly opened inside the corrugated pipe body 1 along the length direction of the corrugated pipe body. Multiple protrusions 23 are set on the outer periphery of the support ring 2 corresponding to the multiple mounting grooves. The multiple protrusions 23 are fixed in the multiple mounting grooves 11 one by one by welding. By setting the mounting grooves 11 and the protrusions 23, the welding area between the support ring 2 and the corrugated pipe body 1 is increased, and the stability of the connection structure between the support ring 2 and the corrugated pipe body 1 is improved.

[0024] like Figures 3 to 5 As shown, multiple support rings 2 are spaced apart and provide multiple supports for the bellows body 1, making the bellows body 1 less prone to damage due to surface stress. The inner ring of the support ring 2 has a recess 22 that smoothly connects with the end of the bellows body 1. Since the support ring 2 occupies a certain volume inside the bellows body 1, the recess 22 in the inner ring of the support ring 2 reduces the volume of the support ring 2. The recess 22 is designed to smoothly connect with the convex ring 42, making the gas or liquid carried by the bellows body 1 flow more smoothly through the support ring 2, thus improving the transmission efficiency of the bellows body 1. Ring 2 has a channel 21 extending through the support ring 2 along the length of the corrugated pipe body 1. The diameter of the openings at both ends of channel 21 is smaller than the cross-sectional diameter of channel 21. A flexible guide post 3 passes through channel 21, and adjacent support rings 2 are connected by the flexible guide post 3. The length of the flexible guide post 3 is not less than the distance between adjacent support rings 2 in their natural state. The flexible guide post 3 is a plastic guide post or a silicone guide post. The flexible guide post 3 includes a column body 31 and two connecting parts 32 respectively disposed at both ends of the column body 31. The cross-sectional diameter of the connecting part 32 is larger than the cross-sectional diameter of the openings at both ends of channel 21. When the bellows body 1 is extended by an external force along its length, it causes multiple support rings 2 of the inner ring to move until the connecting part 32 abuts against the opening of the channel 21, preventing the bellows body 1 from continuing to stretch. The connecting part 32 is specifically a connecting cylinder. When the bellows body 1 is compressed by an external force, it causes multiple support rings to move until two adjacent support rings 2 abut against each other, preventing the bellows body 1 from continuing to compress. This effectively prevents the bellows body 1 from over-extending and over-compressing, protecting the bellows body 1 and making it less prone to damage. There are multiple channels 21, which are evenly arranged around the support rings 2. On the upper part, there are multiple flexible guide pillars 3 corresponding to multiple channels 21. Each flexible guide pillar 3 corresponds to one channel 21. When the corrugated pipe body 1 is stretched, the cross-sectional diameter of the outer periphery of the support ring 2 is at least 70 times the cross-sectional diameter of the pillar 31. Specifically, there are four channels 21 and four flexible guide pillars 3. Since the cross-sectional diameter of the pillar 31 is relatively small compared to the cross-sectional diameter of the support ring 2, the distance between two adjacent flexible guide pillars 3 is relatively large compared to the size of the flexible guide pillar 3. The resistance of the flexible guide pillars 3 on the corrugated pipe body 1 when bending is smaller, so that the corrugated pipe body 1 has good bending ability.

[0025] This application, by setting a flexible guide post 3 and multiple support rings 2 connected by the flexible guide post 3, ensures that while the bellows body 1 is supported by the support rings 2, two adjacent support rings 2 can prevent the bellows body 1 from being over-compressed, and the flexible guide post 3 can prevent the bellows body 1 from being over-stretched, thus protecting the bellows body 1 from damage due to over-compression and over-stretching.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
