Description

Technical Field

[0001] This invention relates to the field of fluid hose connection components, and more specifically to a fluid hose connector. Background Technology

[0002] Fluid hoses are pipes that allow liquids or gases to flow through. They are frequently used in equipment such as sterilizers. When transporting disinfectant solutions over long distances, connectors are used to connect two sections of fluid hoses.

[0003] Please refer to the appendix for the structure of commonly used connector components for connecting hoses. Figure 6 , 7 The connector, consisting of connector A, an intermediate connector, and connector B, has an interface end for connecting the hose to be connected and an adapter end for connecting the intermediate connector. The interface ends of connectors A and B are inserted into the two hose segments respectively, connecting the two hose segments to connectors A and B. Connectors A and B are then connected to the intermediate connector via threads, thus connecting the two hose segments. This connector assembly has the following drawbacks: 1. During connection, connectors A and B need to rotate relative to the intermediate connector, which can cause one or two hose segments to twist, affecting the flow of the medium within the hose; 2. Connecting or disconnecting each pair of hose segments requires multiple operations, which is cumbersome; 3. After connecting multiple hose segments using multiple connector assemblies, the hoses need to be disconnected and rearranged. To facilitate future use, connectors A and B are generally not removed when disconnecting the hoses. However, to prevent the intermediate connector from being lost, it is kept connected to connector A or B and stored away. This results in the hoses needing to be rearranged before the next connection, which is very inconvenient.

[0004] To address the above problems, the present invention provides a fluid hose connector. Summary of the Invention

[0005] To address the aforementioned problems, embodiments of the present invention provide a fluid hose connector, comprising a first connector and a second connector adapted to the first connector. The first and second connectors are respectively adapted to connect to two sections of hose to be connected. The second connector is detachably connected to the first connector for communication between the two sections of hose. The second connector includes an adapter and a connecting section. The connecting section is used to connect to the hose to be connected, and one end of the connecting section passes through the interior of the adapter. The two are in a sealed communication and can rotate relative to each other. The connector of this application not only facilitates the connection of two sections of hose but also allows for rotational adjustment in the connected state, preventing hose twisting from affecting the flow of internal media.

[0006] An embodiment of the present invention provides a fluid hose connector, comprising a first connector and a second connector adapted to be connected to the first connector. The first and second connectors are respectively adapted to be connected to two sections of hose to be connected. The second connector is detachably connected to the first connector for communicating between the two sections of hose.

[0007] The second connector includes an adapter and a connector. The connector is used to connect to the hose to be connected. One end of the connector passes through the interior of the adapter. The connector and the adapter are sealed and connected and can only rotate relative to each other. One end of the adapter is a connection end for fitting with the first connector.

[0008] In some embodiments, a circular through groove is provided inside the adapter, the through groove passes through both ends of the adapter, a limiting block is fixed on the inner wall of the through groove, and an annular limiting groove is fixed on the outside of the connecting pipe around its central axis in the circumferential direction, the connecting pipe passes through the through groove and the limiting block is movably embedded in the limiting groove.

[0009] In some embodiments, an annular groove is provided on the wall of the through groove, the groove being used to accommodate the groove body of the limiting groove.

[0010] In some embodiments, the outer wall of the connecting pipe portion located within the through groove is provided with a plurality of sealing grooves, the sealing grooves being used to install sealing rings.

[0011] In some embodiments, the through groove includes a first groove segment and a second groove segment, the inner diameter of the first groove segment is smaller than the inner diameter of the second groove segment, and the portion of the connecting pipe that passes through the through groove is located in the first groove segment.

[0012] In some embodiments, the transition section between the first and second groove segments is a frustum-shaped groove, and the end of the connecting part that passes through the through groove is a frustum-shaped section suitable for the frustum-shaped groove.

[0013] In some embodiments, the outer wall of the portion of the connector located outside the adapter is provided with a tube-holding groove, and the groove wall on the side of the tube-holding groove near the adapter is an inclined surface that slopes away from the adapter.

[0014] In some embodiments, the connecting end is provided with an external thread, and the connecting end is threadedly connected to the first connector, thereby enabling the interior of the adapter to communicate with the interior of the first connector.

[0015] In some embodiments, a gasket is fitted on the outside of the adapter on the side of the connection end away from the first connector.

[0016] Beneficial effects

[0017] 1. In this embodiment, when connecting two hose sections, the connector of the first connector can rotate independently to align the connecting end of the connecting pipe with the connecting end of the second connector, thus preventing the hose from twisting. The adapter and connecting pipe of the second connector can rotate relative to each other while maintaining a sealing effect. During use, the hose with twist can also be adjusted, which can effectively prevent the flow of the medium inside the hose from being affected by the hose twisting.

[0018] 2. The fluid hose connector of this embodiment consists of two parts: a first connector and a second connector, and is simple to operate;

[0019] 3. The hose using the fluid hose connector of this embodiment, after being disconnected, only has one end with the first connector and one end with the second connector installed. After use, the hose only needs to be placed in a targeted manner, and it can be picked up and used at any time next time. In contrast, the multi-segment hoses with connector components in the prior art, after being disconnected, have the following end of the pipe with one end with connector A, one end with connector A and an intermediate connecting piece, one end with connector B, and one end with connector B and an intermediate connecting piece. The arrangement and the situation before the next use are very troublesome. This embodiment is relatively convenient to arrange and use, and there is no problem of easy loss of components due to the removal of components. Attached Figure Description

[0035] Please see Figures 1-5 A fluid hose connector includes a first connector 1 and a second connector 2. The first connector 1 may be an A connector 3 as described in the background art, or other components with similar structures in the prior art. The second connector 2 is adapted to be connected to the first connector 1. In use, the first connector 1 is connected to the end of one section of hose to be connected, and the second connector 2 is connected to another section of hose to be connected. The first connector 1 and the second connector 2 are detachably connected, which can realize the connection between the two sections of hose to be connected.

[0036] The second connector 2 includes an adapter 21 and a connector 22. The connector 22 is used to connect to the hose to be connected. One end of the connector 22 passes through the interior of the adapter 21. The connector 22 and the adapter 21 are in sealed communication and can only rotate relative to each other.

[0037] For details, please refer to Figure 2-4 In the following description, "left" refers to the attached... Figure 2 The left-hand direction shown refers to the attached... Figure 2 The direction shown to the right:

[0038] The connector 22 is a hollow circular tube. An annular limiting groove 221 is fixed to the outside of the connector 22 around its central axis in a circumferential direction. Multiple sealing grooves are formed on the outside of the connector 22. These sealing grooves are used to install sealing rings 222 and are located to the left of the limiting groove 221. The sealing ring 222 is fitted onto the outside of the connector 22 and then embedded into the sealing groove. Multiple clamping grooves 223 are also formed on the outside of the connector 22. These clamping grooves are annular and located to the right of the limiting groove 221. The groove wall of the clamping groove 223 near the limiting groove 221 is an inclined surface that slopes away from the limiting groove 221. Both the left and right ends of the connector 22 are frustum-shaped. The frustum-shaped design of the right end facilitates insertion of the right end of the connector 22 into the flexible hose.

[0039] The adapter 21 is a horizontally placed cylindrical structure. Its left end is its connecting end 215, which is a cylindrical shape with external threads. The right end of the connecting end is a frustum shape. A through groove is formed inside the connecting end, extending through both the left and right ends. The through groove includes a first groove segment 213 and a second groove segment 214. The first groove segment 213 is located to the left of the second groove segment 214, and its inner diameter is smaller than that of the second groove segment 214. The transition section between the first groove segment 213 and the second groove segment 214 is a frustum-shaped groove structure. A limiting block 211 is fixed to the inner wall of the through groove. The limiting block 211 is an annular block located in the second groove segment 214, and its outer ring is fixed to the inner wall of the second groove segment 214. A retaining groove 212 is also formed on the inner wall of the second groove segment 214. The retaining groove 212 is an annular groove extending circumferentially around the central axis of the through groove.

[0040] The connection structure between the connecting part 22 and the adapter part 21 is as follows: The left end of the connecting part 22 is inserted into the second groove section 214 of the through groove, and the limiting block 211 is movably embedded in the limiting groove 221, so that the connecting part 22 can rotate relative to the adapter part 21, but the two cannot move along the axial direction of the connecting part 22. At this time, the left side of the limiting groove 221 is just embedded in the slot 212, further ensuring that the connecting part 22 and the adapter part 21 cannot have relative displacement in the axial direction. The left end of the connecting part 22 is located at the transition section between the first groove section 213 and the second groove section 214. The frustum-shaped structure of the left end of the connecting part 22 is suitable for communicating the inside of the connecting part 22 with the through groove. The inner wall of the through groove squeezes multiple sealing rings 222, thereby movably sealing the connection between the connecting part 22 and the adapter part 21, ensuring that the two maintain a sealing effect during rotation.

[0041] In this embodiment, the structure of the first connector 1 is as follows: the first connector 1 includes a connecting pipe and a connecting member. The connecting pipe is a hollow circular tube, and a stop block is fixedly provided on its outer wall near the right end. The stop block is preferably a circular annular block fixedly sleeved on the outside of the connecting pipe. An annular groove for installing a sealing gasket is provided on the outer wall of the connecting pipe on the left side of the stop block. The left end of the connecting pipe has a frustum-shaped structure similar to the right end of the connecting pipe 22. Multiple tube-clamping grooves 223 are also provided on the outer wall of the connecting pipe on the left side of the stop block. The groove wall of the tube-clamping groove 223 near the stop block is an inclined surface that slopes away from the stop block. The connecting member is a regular hexagonal prism or a regular polygonal prism. A circular groove penetrating its left and right ends is provided inside the connecting member. Both the connecting pipe and the stop block can pass through the circular groove. The inner wall of the circular groove is provided with an internal thread that matches the external thread of the connecting end 215 of the second connector 2. A circular annular baffle is fixedly sleeved inside the circular groove. The connecting pipe can pass through the middle hole of the baffle, but the stop block cannot pass through. The connector is fitted onto the connecting pipe and positioned to the left of the stop block. Then, the connector is threaded onto the connecting end 215 of the second connector 2, allowing the through groove of the second connector 2 to align with the connecting pipe. In this embodiment, a gasket is fitted onto the outer side of the adapter 21, on the side of the connecting end 215 furthest from the first connector 1. When the first connector 1 and the second connector 2 are connected, the connector presses the gasket against the left end face of the adapter 21.

[0042] The working principle of a fluid hose connector in this embodiment is as follows: First, the connecting part of the first connector 1 is inserted into a section of the hose to be connected, and the first connector 1 is connected to the section of the hose to be connected. Then, the connecting part 22 of the second connector 2 is inserted into the end of another section of the hose to be connected, and the second connector 2 is connected to the hose to be connected. Then, the connecting end 215 is aligned with the right end of the connecting part of the first connector 1. The connecting part of the first connector 1 is rotated to connect the first connector 1 and the second connector 2. At this time, the two hoses to be connected are connected. During use, the rotation of the connecting part 22 and the hose connected to the connecting part 22 does not affect the connection effect of the two hoses.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
