Description

Technical Field

[0001] This invention relates to the field of pipeline technology, specifically to the connection structure of hoses and hose connectors. Background Technology

[0002] In bathroom systems, flexible hoses are typically used for connection. These hoses usually need to be connected to the outside via connectors to facilitate the transmission of bathroom pipes. When connecting existing flexible hoses to hose connectors, the hose is usually directly inserted into the hose connector. This connection method not only makes the hose prone to detachment but also results in poor sealing of the connection. Summary of the Invention

[0003] This application provides a connection structure between a hose and a hose connector, which makes it difficult for the hose and hose connector to detach, and provides a good seal between the hose and hose connector.

[0004] The connection structure between the hose and the hose connector provided in this application includes:

[0005] The hose connector includes a first pipe section and a second pipe section. The first pipe section and the second pipe section are coaxially connected and communicate with each other. A radial protruding ring is provided on the outer wall of the connection between the first pipe section and the second pipe section. Multiple reverse teeth are provided on the outer wall of the second pipe section. The multiple reverse teeth are arranged sequentially along the axial direction of the second pipe section, and each reverse tooth extends circumferentially around the axial direction of the second pipe section.

[0006] A flexible hose is fitted onto the second pipe section, and the end of the hose abuts against one surface of a radial convex ring.

[0007] Preferably, the hose includes a hose body, a metal braided hose, a rubber hose, and a connecting sleeve. The hose body is fitted onto the second pipe section, the metal braided hose is fitted onto the outer wall of the hose body, the rubber hose is fitted onto the outer wall of the metal braided hose, and the connecting sleeve is fitted onto the outer wall of the rubber hose. One end of the connecting sleeve is provided with a radially inwardly extending annular portion. One surface of the annular portion abuts against one surface of a radially protruding ring, and the other surface of the annular portion abuts against the ends of the hose body, the metal braided hose, and the rubber hose. The connecting sleeve is made of metal material and can be deformed by compression to clamp the hose onto the second pipe section.

[0008] Preferably, the connecting structure further includes a rotating member and several sliding members. An annular groove extending circumferentially around the axis of the radial convex ring is provided on the surface of the radial convex ring near the connecting sleeve. An annular groove recessed radially along the radial convex ring is provided on the inner circumferential wall of the annular groove. Several through holes extending radially through the radial convex ring to the outer circumferential surface of the radial convex ring are provided on the outer circumferential wall of the annular groove. The sliding members are provided in correspondence with the through holes. Each sliding member is slidably disposed in the through hole. The annular groove is used to accommodate the annular part of the connecting sleeve. The first end of each sliding member abuts against the outer circumferential edge of the annular part. The second end of each sliding member extends out of the outer circumferential surface of the radial convex ring. The second end of the sliding member is spherical.

[0009] The rotating component includes a first body, a second body, and a connecting ring. The first body is rotatably fitted onto the first pipe section, and the second body is rotatably fitted onto the outer circumferential surface of the radial convex ring. The connecting ring connects the first body and the second body. Several grooves are provided on the inner circumferential wall of the second body, and each groove corresponds to a sliding component. The second end of each sliding component is located in the corresponding groove. Each groove extends around the axis of the radial convex ring and its depth gradually decreases.

[0010] When the rotating part is rotated, the second body pushes each sliding part toward the center of the radial convex ring, so that the first end of each sliding part presses the annular part of the connecting sleeve into the annular groove.

[0011] Preferably, each through hole has a radially extending convex ring on its inner wall. Each slider is divided into a first section, a second section, and a third section along the axial direction. The first, second, and third sections are arranged coaxially. The first and third sections have the same diameter, while the second section has a smaller diameter than the first section. The second section of each slider can be movably fitted into the convex ring in its respective through hole. The end face of the third section of each slider near the first section is used to abut against the first end face of the convex ring in its respective through hole. Each second section of each slider is fitted with a compression spring. The first end of each compression spring abuts against the second end face of the convex ring in its respective through hole, and the second end of each compression spring abuts against the end face of the first section in its respective through hole.

[0012] Preferably, a pressure plate is provided at the end of the third section away from the first section. The shape of the pressure plate matches the outer periphery of the annular section, and the pressure plate is used to press against the outer periphery of the annular section.

[0013] Preferably, a protrusion is fixedly provided on the inner wall of the first body, and a groove is provided on the outer wall of the first pipe section. The groove extends around the axis of the first pipe section, and the protrusion is slidably provided in the groove.

[0014] When the first set of parts rotates on the first pipe section, the protrusion slides along the slide groove. When the protrusion slides to one end of the slide groove, the second end of each sliding member is located at the shallowest part of its respective groove; when the protrusion slides to the other end of the slide groove, the second end of each sliding member is located at the deepest part of its respective groove.

[0015] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0016] The connection structure of this application has multiple reverse teeth on the outer wall of the second pipe section of the hose connector, and the hose is sleeved on the second pipe section. The reverse teeth make it difficult for the hose to fall off the second pipe section, and the reverse teeth also make the hose and the hose connector have a good seal. Attached Figure Description

[0025] Example 1

[0026] like Figure 1 As shown, the connection structure of the hose and hose connector in this embodiment includes a hose connector and a hose.

[0027] The hose connector includes a first pipe section 11 and a second pipe section 12, which are coaxially connected. The inner holes of the first pipe section 11 and the second pipe section 12 are interconnected. A radial protruding ring 13 is provided on the outer wall of the connection between the first pipe section 11 and the second pipe section 12. A plurality of reverse teeth 121 are provided on the outer wall of the second pipe section 12. The plurality of reverse teeth 121 are arranged sequentially along the axial direction of the second pipe section 12, and each reverse tooth 121 extends circumferentially around the axial direction of the second pipe section 12. Each reverse tooth 121 is annular.

[0028] The hose is fitted onto the second pipe section 12, and the end of the hose abuts against a surface of the radial protrusion ring 13. The first pipe section 11 is used to connect to the external pipeline so that the hose is connected to the external pipeline through the hose connector.

[0029] The hose includes a hose body 21, a metal braided hose 22, a rubber hose 23, and a connecting sleeve 24. The hose body 21 is fitted onto the second pipe section 12. The metal braided hose 22 is fitted onto the outer wall of the hose body 21. The rubber hose 23 is fitted onto the outer wall of the metal braided hose 22. The connecting sleeve 24 is fitted onto the outer wall of the rubber hose 23. One end of the connecting sleeve 24 is provided with a radially inwardly extending annular portion 241. One surface of the annular portion 241 abuts against one surface of the radially protruding ring 13, and the other surface of the annular portion 241 abuts against the ends of the hose body 21, the metal braided hose 22, and the rubber hose 23. The connecting sleeve 24 is made of metal material and can be compressed and deformed to clamp the hose onto the second pipe section 12. When the hose is connected to the hose connector, the connecting sleeve 24 is compressed and deformed so that the connecting sleeve 24 clamps the hose onto the second pipe section 12, so that the connection between the hose and the second pipe section 12 is stable.

[0030] Example 2

[0031] like Figures 2-5 As shown, compared to Embodiment 1, the connection structure of this embodiment further includes a rotating member 31 and several sliding members 32. An annular groove 131 extending circumferentially around the axis of the radial protruding ring 13 is provided on a surface of the radial protruding ring 13 near the connecting sleeve 24. An annular groove 132, radially recessed along the radial protruding ring 13, is provided on the inner circumferential wall of the annular groove 131. Several through holes 133 extending radially through the radial protruding ring 13 to the outer circumferential surface of the radial protruding ring 13 are provided on the outer circumferential wall of the annular groove 131. Each sliding member 32 corresponds to one of the through holes 133. Both are slidably disposed in the through hole 133. Each slider 32 can slide in the radial direction of the radial protrusion ring 13 within its respective through hole 133. The annular groove 131 is used to accommodate the annular portion 241 of the connecting sleeve 24. The first end of each slider 32 abuts against the outer periphery of the annular portion 241, and the second end of each slider 32 extends out of the outer periphery of the radial protrusion ring 13. The second end of each slider 32 is spherical. When the first end of the slider 32 applies pressure to the outer periphery of the annular portion 241, the connecting sleeve 24 can be deformed by force so that the annular portion 241 is pressed into the annular groove 132.

[0032] The rotating component 31 includes a first body portion 311, a second body portion 312, and a connecting ring portion 313. The first body portion 311 is rotatably fitted onto the first pipe section 11, and the second body portion 312 is rotatably fitted onto the outer circumferential surface of the radial convex ring 13. The connecting ring portion 313 connects the first body portion 311 and the second body portion 312. The first body portion 311, the second body portion 312, and the connecting ring portion 313 are integrally formed. The connecting ring portion 313 abuts against the other surface of the radial convex ring 13. The inner surface of the second body portion 312... Several grooves are provided on the peripheral wall, and the grooves are provided one-to-one with the sliding members 32. The second end of each sliding member 32 is located in the corresponding groove. Each groove extends around the axis of the radial convex ring 13 and the depth gradually decreases. In this way, when the second body part 312 rotates in one direction on the outer peripheral surface of the radial convex ring 13, the groove can compress the sliding member 32, so that the sliding member 32 moves towards the center position of the radial convex ring 13, so that the first end of the sliding member 32 applies pressure to the outer peripheral edge of the annular part 241.

[0033] When the rotating member 31 is rotated, the depth of the groove gradually decreases along the axial direction surrounding the radial convex ring 13, allowing the second body 312 to push each sliding member 32 toward the center of the radial convex ring 13. This causes the first end of each sliding member 32 to press the annular portion 241 of the connecting sleeve 24 into the annular groove 132. In this way, several sliding members 32 form a radial clamping effect on the annular portion 241 of the connecting sleeve 24. At the same time, the annular groove 132 forms an axial limit on the annular portion 241 of the connecting sleeve 24. Thus, by rotating the rotating member 31, the connecting sleeve 24 can be firmly fixed on the second pipe section 12. In this way, when moving the hose, the hose and hose connector are not easy to loosen. The hose and hose connector can be placed on the extrusion machine to extrude and deform the connecting sleeve 24, so that the connecting sleeve 24 is clamped on the toothed portion 121 of the second pipe section 12.

[0034] Each through hole 133 has a radially extending protruding ring portion 1331 on its inner wall. Each sliding member 32 is axially divided into a first section 321, a second section 322, and a third section 323. The first section 321, the second section 322, and the third section 323 are arranged coaxially. The first section 321 and the third section 323 have the same diameter, while the diameter of the second section 322 is smaller than that of the first section 321. The first sections 321 are all close to the outer peripheral surface of the radial protruding ring 13, and the third sections 323 are all close to the connecting sleeve 24. The second section 322 of each sliding member 32 can be movably fitted into the protruding ring portion 1331 in its respective through hole 133. The end face of the third section 323 of each sliding member 32 that is close to the first section 321 is used to interact with the protruding ring portion in its respective through hole 133. The first end face of 1331 abuts against each other, and a compression spring 33 is fitted on the second section 322 of each slider 32. The first end of each compression spring 33 abuts against the second end face of the convex ring 1331 in its respective through hole 133, and the second end of each compression spring 33 abuts against the end face of the first section 321 in its respective through hole 133. In this way, the compression spring 33 can apply a force to the slider 32 to move in the direction of the outer peripheral surface of the radial convex ring 13, so that when the slider 32 is located at the deepest part of its groove, the end face of the third section 323 of each slider 32 near the first section 321 abuts against the first end face of the convex ring 1331 in its respective through hole 133, so that the annular part 241 of the connecting sleeve 24 will not be blocked by the slider 32 when it is inserted into the annular groove 131.

[0035] Each end of the third section 323 away from the first section 321 is provided with a pressure plate portion 324. The shape of the pressure plate portion 324 matches the outer periphery of the annular portion 241. The pressure plate portion 324 is used to press against the outer periphery of the annular portion 241. In this way, when the sliding member 32 moves, the pressure plate portion 324 applies force to the annular portion 241, so that the annular portion 241 is more stable under force.

[0036] A protrusion 314 is fixedly provided on the inner wall of the first body 311, and a groove 111 is provided on the outer wall of the first pipe section 11. The groove 111 extends around the axis of the first pipe section 11, and the protrusion 314 is slidably disposed in the groove 111.

[0037] When the first set of body parts 311 rotates on the first pipe section 11, the protrusion 314 slides along the slide groove 11. When the protrusion 314 slides to one end of the slide groove 11, the second end of each sliding member 32 is located at the shallowest part of its respective groove. When the protrusion 314 slides to the other end of the slide groove 11, the second end of each sliding member 32 is located at the deepest part of its respective groove. In this way, by sliding the protrusion 314 in the groove, the rotation angle of the first set of body parts 311 on the first pipe section 11 can be limited, so that when it is necessary to press the annular part 241 of the connecting sleeve 24 by the sliding member 32, the rotation angle of the first set of body parts 311 is accurate.
