Description

Technical Field

[0001] This utility model belongs to the field of hose connector technology, and in particular relates to a hose connector with controllable rotation angle. Background Technology

[0002] A hose connector is a component used to connect hoses. It helps users quickly and safely connect and disconnect pipelines at critical connection points, making the transmission of fluids and gases more efficient and flexible.

[0003] In the field of vacuum cleaner hoses, while traditional vacuum cleaner hose connectors can reliably connect the hose to the main unit or accessories, their unrestricted rotation characteristics expose many drawbacks in actual use. For example, when users need to simultaneously insert a thin hose (such as a cleaning brush head connector) or cable (such as a power cord for a motorized brush head) into the hose, if the connector lacks rotation angle restrictions, the hose is prone to excessive twisting, causing the internal thin tube or cable to become tangled or knotted. This not only directly hinders the smoothness of cleaning work (e.g., requiring frequent stops to untangle the cable), but may also cause safety hazards due to excessive cable twisting (e.g., cable damage, short circuits), and may even cause permanent deformation of the hose itself due to long-term uneven stress, ultimately reducing vacuuming efficiency.

[0004] Furthermore, when operating in complex spaces (such as under furniture or in corners), the unrestricted rotation of the hose connector makes it more prone to tangling due to inertia, forcing users to spend extra time untangling and significantly reducing cleaning efficiency. This problem is particularly prominent in scenarios requiring long-term continuous operation (such as commercial cleaning or large-area home cleaning), directly impacting equipment durability and user satisfaction.

[0005] Currently, Chinese patent CN210297154U discloses a rotatable hose installation connector, which includes a hose. A rotating component is fixedly sleeved at the top of the hose, and a filler located in the bottom cavity of the rotating component is movably sleeved at the top of the hose. A telescopic spring located outside the hose is fixedly connected to the bottom of the rotating component. A correction ring located below the rotating component is fixedly sleeved on the outer surface of the hose, and the bottom end of the telescopic spring is fixedly connected to the top of the correction ring. This rotatable hose installation connector, by creating a groove at the bottom of the connecting sleeve and placing ball bearings in the inner cavity of the groove, allows the rotating component to rotate when the rotating component is rotated. This rotation, in turn, drives the rotation of the hose, facilitating convenient adjustment of the hose and avoiding the time wasted by repeatedly removing the hose, thus improving work efficiency.

[0006] However, this structure cannot limit the angle of rotation and still suffers from excessive distortion.

[0007] Chinese Patent CN217063170U – A rotatable hose connector, comprising: a first connector, one end of which is a threaded end and the other end is a first connecting end, the inner surface of which has a circumferentially arranged snap-fit ​​groove; a second connector, one end of which is a second connecting end and the other end is a threaded end, the outer surface of which has a circumferentially arranged snap-fit ​​groove corresponding to the snap-fit ​​groove; and a rotary bearing, the outer portion of which is embedded in the snap-fit ​​groove, and the inner portion of which can be snapped into the snap-fit ​​groove, so that the first connector and the second connector are connected in a rotatable structure. The use of a rotary bearing for rotatable connection makes installation and use very convenient and allows for flexible rotation; at the same time, the snap-fit ​​groove and snap-fit ​​groove further enhance the reliability of the rotary bearing rotatable connection. This structure can only achieve omnidirectional rotation and cannot achieve rotation at a specific angle. Utility Model Content

[0008] The purpose of this invention is to provide a hose connector with controllable rotation angle, in order to solve the problem that existing hose connectors and hose connections cannot achieve restricted rotation angle.

[0009] To achieve the above objectives, this utility model adopts the following technical solution: a flexible hose connector with controllable rotation angle.

[0010] include:

[0011] The connector body is provided with a limit block and a rotatable limit ring, wherein the limit block is used to limit the rotation angle of the limit ring;

[0012] A flexible hose, which is connected to one end of the connector body;

[0013] The fitting connector is located at the other end of the connector body and is connected to the limiting ring.

[0014] As a further description of the above technical solution:

[0015] The connector body is provided with a limiting groove, and the limiting ring is located in the limiting groove.

[0016] As a further description of the above technical solution:

[0017] The limiting ring has an opening, and the limiting block is connected to the limiting groove and located inside the opening.

[0018] As a further description of the above technical solution:

[0019] The limiting ring is provided with a number of locking blocks, and the inner wall of the accessory connector is provided with a number of locking slots, and the number of locking slots and the number of locking blocks are matched with each other.

[0020] As a further description of the above technical solution:

[0021] The hose and the connector are an integral structure.

[0022] As a further description of the above technical solution:

[0023] A sealing ring is provided on the connector body, and the sealing ring abuts against the inner wall of the fitting connector.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0025] 1. In this utility model, a limiting groove is set on the connector body, and a limiting block is set in the limiting groove. A limiting ring with an opening is rotatably connected in the limiting groove, and the limiting block is placed in the opening. When the slot on the inner wall of the accessory connector is engaged with the locking block on the limiting ring, the connection between the accessory connector and the connector body can be realized. Because of the setting of the limiting block, the accessory connector can only rotate at a specific angle when it is rotated. When it is installed on the vacuum hose, it will not be excessively twisted and damaged, nor will it cause the thin tube or cable inside the hose to become tangled or knotted, affecting the vacuuming effect. It can also be applied to scenarios where only a specific angle of the hose needs to be rotated.

[0026] 2. In this utility model, the rotation angle between the connector body and the accessory connector can be controlled by adjusting the opening distance of the limiting ring. Specifically, this is achieved by limiting the angle between the opening and the limiting block around the center of the connector, thereby meeting the needs of different application scenarios.

[0040] Please see Figure 1-4 This utility model provides a technical solution: a flexible hose connector with controllable rotation angle.

[0041] include:

[0042] The connector body 1 is provided with a limiting block 2 and a rotatable limiting ring 3, wherein the limiting block 2 is used to limit the rotation angle of the limiting ring 3;

[0043] Hose 4 is connected to one end of the connector body 1;

[0044] The fitting connector 5 is located at the other end of the connector body 1 and is connected to the limiting ring 3.

[0045] The connector body 1 is provided with a limiting groove 6, and the limiting ring 3 is located in the limiting groove 6.

[0046] The limiting ring 3 is provided with an opening 7, and the limiting block 2 is connected to the limiting groove 6 and located inside the opening 7.

[0047] The limiting ring 3 is provided with a plurality of locking blocks 8, and the inner wall of the accessory connector 5 is provided with a plurality of locking grooves 9, which are matched with each other to achieve a specific angle of rotation between the accessory connector and the connector body.

[0048] The hose 4 and the connector body 1 are an integral structure. The hose can be glued to the inner wall of the connector body, or it can be connected to the inner wall of the connector body by overmolding to form an integral structure. This improves the overall stability of the structure.

[0049] A sealing ring 10 is provided on the connector body 1, and the sealing ring 10 abuts against the inner wall of the accessory connector 5. This ensures the sealing of the connection between the accessory connector and the connector body, improving the sealing effect and preventing dust or other media from leaking out when used in vacuum cleaners or other media conveying scenarios.

[0050] Working principle: By setting a limiting groove on the connector body and setting a limiting block in the limiting groove, a limiting ring with an opening can be rotatably connected in the limiting groove, and the limiting block is placed in the opening. When the slot on the inner wall of the accessory connector engages with the locking block on the limiting ring, the connection between the accessory connector and the connector body can be realized. Because of the setting of the limiting block, the accessory connector can only rotate at a specific angle when it is rotated. When it is installed on the vacuum hose, it will not be excessively twisted and damaged, nor will it cause the thin tube or cable inside the hose to become tangled or knotted, affecting the vacuuming effect. It can also be used in scenarios where only a specific angle of the hose needs to be rotated.

[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
