Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline joints, and particularly relates to a folding joint connecting hose device. Background Art

[0002] A pipe joint is a connector used to connect pipes in a fluid pathway. Common pipe joints generally use welding or threaded connections to connect pipes, and are mainly used for small-diameter low-pressure pipelines. Pipe joints are widely used in water supply and drainage construction in the fields of water supply, drainage, electricity, metallurgy, urban construction, and petroleum. With the development of society, in order to achieve better connections, pipe joints are designed into a folding structure so that the connected pipes can be bent to meet different usage requirements. The hoses on existing folding joints generally use fixed connections, which are inconvenient to disassemble and install, and it is not convenient to replace the hoses after they are scrapped after long-term use. Utility Model Content

[0003] The purpose of the present invention is to provide a folding joint connecting hose device to solve the problems raised in the above background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] The foldable joint connecting hose device includes a first foldable joint, a second foldable joint and a damping rotating shaft. The first foldable joint and the second foldable joint are rotatably connected via the damping rotating shaft, and the first foldable joint and the second foldable joint are rotatably connected via the damping rotating shaft, so that the first foldable joint and the second foldable joint can be folded, thereby allowing the connected pipe to be bent, which can meet different usage requirements. The first foldable joint and the second foldable joint are respectively connected to the outside of the first foldable joint with the first hose connecting component and the second hose connecting component. A corrugated hose is connected between the first hose connecting component and the second hose connecting component. The corrugated hose is connected to the first hose connecting component and the second hose connecting component through the first hose connecting component and the second hose connecting component. It can be disassembled by rotating the connecting screw sleeve in the opposite direction. The corrugated hose is easy to replace after being scrapped for long-term use. The inner cavity of the end of the first foldable joint is provided with a filter component. The filter component can intercept and filter impurities in the water entering the foldable joint, thereby preliminarily purifying the water quality.

[0006] The first hose connection assembly and the second hose connection assembly both include a first joint and a second joint. The inner cavities of the first joint and the second joint are respectively provided with a sealing assembly and a push rod. A connecting screw sleeve is sleeved on the outer side of the first joint. After the first joint and the second joint are connected and fixed, the push rod squeezes the sealing assembly to open, and water can flow smoothly. When the connecting screw sleeve is rotated in the opposite direction to remove the second joint from the first joint and replace the corrugated hose, the sealing assembly will automatically seal and cut off the flow, making it easy to replace the corrugated hose.

[0007] Furthermore, the first folding joint and the second folding joint both include a water collecting shell, a pipe connecting portion is provided on the outside of the water collecting shell, and a connecting flange is fixedly provided at the end of the pipe connecting portion. The pipe can be connected through the connecting flange, which facilitates the installation of the pipe at the end of the first folding joint and the second folding joint.

[0008] Furthermore, the first joint includes a first joint body and a connecting pipe fitting arranged at the end of the first joint body. A first water flow channel is provided in the middle of the first joint body, and an annular part is provided on the outside of the first joint body. The connecting screw sleeve can be clamped on the outside of the first joint body through the annular part, and the connecting screw sleeve can be rotated after being clamped.

[0009] Furthermore, the second connector includes a second connector body, a second water flow channel is opened on the second connector body, an external thread is provided on the outer side of the end of the second connector body, and a hose connection part is provided at the end of the second connector body away from the external thread. An anti-slip protrusion is provided on the outer side of the hose connection part. When used, the corrugated hose is put on the outer side of the hose connection part, and then locked and fixed by the clamping piece. The anti-slip protrusion can improve the connection strength between the corrugated hose and the hose connection part, so that the corrugated hose is not easy to fall off.

[0010] Furthermore, the sealing assembly includes a return spring, one end of which is fixedly connected to a sealing plug, and the sealing plug matches the first water flow channel. After the first joint and the second joint are connected and fixed, the push rod squeezes the sealing assembly to open, and water can flow smoothly through at this time. When the connecting sleeve is rotated in the opposite direction to remove the second joint from the first joint and replace the corrugated hose, the sealing plug on the sealing assembly will automatically reset and seal under the action of the return spring. There is no need to close the main valve when replacing the corrugated hose, which facilitates the replacement of the corrugated hose.

[0011] Furthermore, the connecting screw sleeve includes a screw sleeve body, the inner wall of the screw sleeve body is provided with an internal thread and an annular groove, and the annular groove matches the annular part, and the outer side of the screw sleeve body is provided with an anti-slip protrusion, which can increase the friction of the hand and facilitate the rotation of the connecting screw sleeve.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The utility model can be folded when in use so that the connected pipes can be bent to meet different usage requirements. The corrugated hose is connected to the second hose connecting assembly through the first hose connecting assembly, which is convenient for installation and disassembly. The corrugated hose can be easily replaced after being scrapped after long-term use. By arranging a blocking assembly inside the first joint, the blocking assembly can intercept the flow, and water can only pass when the first joint is connected to the second joint. When the second joint is removed from the first joint to replace the corrugated hose, the blocking assembly will automatically block and intercept the flow. There is no need to close the main valve when replacing the corrugated hose, and the corrugated hose is easy to replace. BRIEF DESCRIPTION OF THE DRAWINGS
