Description

Technical Field

[0001] This utility model relates to the field of corrugated rubber hose technology, and more specifically, to a corrugated rubber hose that facilitates radial expansion and contraction. Background Technology

[0002] Rubber corrugated pipes are pipes made of rubber material with a corrugated shape. They are commonly used to transport liquid or gaseous media. They have good pressure resistance, corrosion resistance and wear resistance, and can be bent and flexed to adapt to different installation environments. Therefore, rubber corrugated pipes are widely used in many industrial fields.

[0003] In some applications of rubber corrugated hoses, such as at the air intake pipe of vehicle air filters, the elasticity of rubber and the tensile and compressive properties of the corrugations are utilized to ensure good vibration isolation, tensile and compressive effects at the air intake pipe, enabling the air filter to function properly. However, existing corrugated hoses used in automobiles are mostly straight-line corrugated hoses. Therefore, in some high-displacement vehicles, insufficient rubber support leads to excessive deformation during air intake, which can cause the rubber hose to collapse under high flow negative pressure. This results in less smooth airflow within the hose, leading to insufficient air intake and affecting the vehicle's normal operation. Therefore, a corrugated rubber hose with radial expansion and contraction is designed. Utility Model Content

[0004] The purpose of this invention is to provide a corrugated rubber tube that facilitates radial expansion and contraction, in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model provides a corrugated rubber tube that facilitates radial expansion and contraction, comprising: a rubber tube body, two connecting pipes respectively connected to both ends of the rubber tube body, a support assembly disposed within the rubber tube body, two connectors disposed at both ends of the support assembly and on the two connecting pipes, and a limiting assembly installed on the support assembly and placed outside the rubber tube body;

[0014] The plurality of rubber rings are respectively disposed within the plurality of wave crests, and the inner walls of the plurality of wave crests are adapted to the outer walls of the plurality of rubber rings.

[0015] Furthermore, the connector includes a connector with both ends threadedly connected to one of the positioning tubes and the connecting tube respectively, two positioning screws threadedly connected to one of the limiting blocks and one of the connecting tubes respectively, and two positioning holes symmetrically opened on the connector.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0032] like Figure 1-5 As shown, a corrugated rubber hose that facilitates radial expansion and contraction includes: a rubber hose body 1, two connecting pipes 2 respectively connected to both ends of the rubber hose body 1, a support component 3 disposed in the rubber hose body 1, two connecting pieces 4 disposed at both ends of the support component 3 and on the two connecting pipes 2, and a limiting component 5 installed on the support component 3 and placed outside the rubber hose body 1.

[0033] The rubber tube body 1 includes two connecting portions 8, and a plurality of crests 6 and troughs 7 disposed between the two connecting portions 8, wherein the inner diameter of the two connecting portions 8 is larger than the inner diameter of the plurality of troughs 7.

[0034] The supporting component 3 is adapted to support the two connecting parts 8 and the plurality of troughs 7;

[0035] The two connectors 4 are adapted to connect the two connecting pipes 2 to the rubber tube body 1;

[0036] The limiting component 5 is adapted to restrict the movement space of the two connecting parts 8.

[0037] In use, the supporting component 3 is assembled into the rubber tube body 1. Through the support of the supporting component 3 within the rubber tube body 1, the troughs 7 and crests 6 all possess strong compressive strength, ensuring the compressive and deformation resistance of the rubber tube body 1. When the rubber tube body 1 is affected by the airflow inside the tube and undergoes radial expansion and contraction, it can effectively limit the deformation of the rubber tube body 1, avoiding the phenomenon of easy collapse under high flow negative pressure that occurs in existing rubber corrugated pipes during use. This ensures the normal use of the rubber corrugated pipe. Simultaneously, the supporting component 3 can create a stable gas flow space within the rubber tube body 1, preventing the troughs 7 and crests 6 in the rubber tube from causing turbulence or interference with gas flow, effectively ensuring the stable delivery of airflow by the corrugated rubber tube, thereby guaranteeing… The vehicle operates normally; and during the installation of the corrugated rubber hose, the connection between the rubber hose body 1 and the air transmission pipe can be stably completed through the set connector 4, ensuring the stability of the connection and preventing loosening due to vibration during use. This effectively ensures the airtightness of the internal space of the rubber hose body 1 during use, preventing gas leakage during gas transmission through the corrugated rubber hose. At the same time, when using the corrugated rubber hose, the limiting component 5 is installed on the abutment component, thereby effectively limiting the axial expansion and contraction of the rubber hose body 1 during use, ensuring that the rubber corrugated hose is not overstretched, avoiding damage due to excessive stretching of the rubber hose body 1, and preventing the input pipe 10 in the abutment component 3 from detaching from the output pipe 11 during use, thus ensuring the normal use of the corrugated rubber hose.

[0038] Optionally, the supporting component 3 includes two positioning tubes 9 that are respectively fitted and slidably inserted into the two connecting parts 8, an input tube 10 and an output tube 11 that are respectively connected to the two positioning tubes 9, a plurality of limiting blocks 12 that are symmetrically fixed on the outer walls of the two connecting tubes 2, and a plurality of limiting grooves 13 that are respectively opened on the two connecting parts 8 and correspond to the plurality of limiting blocks 12.

[0039] The input tube 10 is fitted and slidably inserted into the input tube 10;

[0040] Both the input pipe 10 and the output pipe 11 are fixedly fitted with rubber sleeves 14. In use, the input pipe 10 and the output pipe 11 are inserted into several peaks 6 and troughs 7 from the two connecting parts 8, respectively, so that the output pipe 11 is fitted over the input pipe 10. At this time, through the cooperation of several limiting blocks 12 and several limiting grooves 13, the two connecting parts 8 are stably fitted over the two positioning rods, thereby completing the stable connection between the rubber tube body 1 and the supporting assembly 3. During operation, the output pipe 11 and the input pipe 10 allow for the flow or gas transport, avoiding turbulence caused by the peaks 6 and troughs 7, which would affect the fluid and gas transport effect. The input pipe 10 and output pipe 11 can effectively support several troughs 7 to improve the overall deformation resistance of the rubber tube body 1. When radial expansion and contraction occur, excessive deformation and damage can be avoided. During the production of the rubber tube body 1, steel rings integrally formed with the rubber corrugated tube body can be set at several troughs 7 to further improve the compressive strength of the rubber tube body 1. The rubber rings on the input pipe 10 and output pipe 11 can protect the contact points between the input pipe 10 and output pipe 11 at several troughs 7 to ensure the support effect of the input pipe 10 and output pipe 11 on several troughs 7. When the input pipe 10 moves in the output pipe 11, the rubber sleeve 14 can also provide a certain degree of sealing at the contact points.

[0041] Optionally, the supporting component 3 further includes several rubber rings 15 that are movably sleeved on the outside of the input pipe 10 and the output pipe 11;

[0042] A plurality of rubber rings 15 are respectively disposed within a plurality of corrugated peaks 6, and the inner walls of the corrugated peaks 6 are adapted to the outer walls of the rubber rings 15. The plurality of rubber rings 15 can provide abutment support to the corrugated peaks 6. When the rubber tube body 1 is compressed and undergoes radial expansion and contraction, the corrugated peaks 6 will be compressed first. Since the outer walls of the plurality of rubber rings 15 are adapted to the inner walls of the corrugated peaks 6, the force on the corrugated peaks 6 can be evenly distributed, thereby effectively improving the pressure resistance and deformation resistance of the corrugated tube. This allows the corrugated peaks 6 to quickly return to their original position after radial expansion and contraction under pressure, avoiding deformation and affecting use, thus improving the service life of the rubber tube body 1.

[0043] Optionally, the connector 4 includes a connector 16 with both ends threadedly connected to one of the positioning tubes 9 and the connecting tube 2 respectively, two positioning screws 17 threadedly connected to one of the limiting blocks 12 and one of the connecting tubes 2 respectively, and two positioning holes 18 symmetrically opened on the connector 16.

[0044] The two positioning holes 18 correspond to the two positioning screws. In use, the positioning tube 9 and the connecting tube 2 are respectively threaded and rotated at both ends of a connecting joint 16. After rotation into place, positioning screws are respectively rotated and installed on one of the limiting blocks 12 on the connecting positioning tube 9 and on the connected connecting tube 2. When the tail ends of the two positioning screws are respectively engaged in the two positioning holes 18 on the connecting joint 16, the rotation of the connecting joint 16 relative to the connecting tube 2 and the positioning tube 9 is effectively restricted, making it less likely for the threaded connection between the connecting tube 2 and the positioning tube 9 and the connecting joint 16 to loosen. This effectively improves the stability of the connection between the connecting tube 2 and the positioning tube 9 and avoids the problem of loose connection affecting airtightness.

[0045] Optionally, the limiting component 5 includes two mounting seats 19 that are threadedly connected to two positioning tubes 9 through two of the limiting blocks 12, two mounting slots 20 that are respectively opened on the two mounting seats 19, a limiting rod 21 and a limiting post 22 that are respectively movably installed in the two mounting slots 20, a movable slot 23 opened in the limiting post 22, a limiting block 24 that is movably installed in the movable slot 23, and two fixing nuts 25 that are threadedly connected to one end of the limiting rod 21 and the limiting post 22 respectively.

[0046] The other end of the limiting rod 21 passes through the limiting post 22 and is fixedly connected to the limiting block 24. In use, the two mounting seats 19 are first rotatably installed on two of the limiting blocks 12 on the two positioning tubes 9. Then, the limiting rod 21 and the limiting post 22 are respectively installed on the two mounting seats 19 by the two fixing nuts 25. When the rubber tube body 1 expands and contracts, causing the two positioning tubes 9 to move closer or further away from each other, the limiting block 24 moves in the movable groove 23, thereby limiting the horizontal movement distance of the rod 21 relative to the limiting post 22. This prevents the rubber tube body 1 from being overstretched, which could cause damage to several troughs 7 and several crests 6, thus protecting the safety of the corrugated rubber tube. At the same time, it can prevent the input tube 10 from detaching from the output tube 11 during use, ensuring the normal use of the corrugated rubber tube.

[0047] Optionally, the connector 4 further includes two sealing rings 26 that abut against the connection joint 16 and the positioning tube 9, and between the connection joint 16 and the connection tube 2, respectively. After the connection joint 16 completes the connection and limitation between one of the connection tubes 2 and one of the positioning tubes 9, the two sealing rings 26 are squeezed, thereby performing an effective sealing operation to ensure the sealing effect at the connection between the connection tube 2 and the support component 3, thereby effectively improving the airtightness of the rubber tube body 1 during use.

[0048] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
