Description

Technical Field

[0001] This utility model relates to the field of pipe fitting technology, and in particular to a quick connector suitable for various pipe diameters. Background Technology

[0002] In fluid transmission systems, pipe connections are an indispensable part. Traditional pipe connection methods, such as welding and flange connections, while providing stable connections, are complex and time-consuming to operate. Furthermore, different connection methods and tools are required for different pipe diameters, significantly increasing construction difficulty and cost. Especially in applications requiring frequent replacement or adjustment of pipe connections, such as laboratories, testing equipment, and temporary water supply systems, a pipe fitting that is quick, easy, and suitable for multiple pipe diameters is of paramount importance.

[0003] While some quick-connect couplings exist on the market, they still have shortcomings in adapting to various pipe diameters and ensuring sealing and stability. For example, some couplings can only be used with pipes of specific sizes, requiring different coupling models for different pipe diameters; while some couplings can be adjusted to fit different pipe diameters, the operation is complex, and sealing and stability are difficult to guarantee. Therefore, developing a coupling that can quickly and easily connect pipes of different diameters while ensuring good sealing and stability is of great significance. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as some connectors only being compatible with pipes of specific sizes, requiring different models of connectors for pipes of different diameters, and some connectors being adaptable to different pipe diameters through adjustment, but which are complex to operate and have difficulty in ensuring sealing and stability. Therefore, this invention proposes a quick connector suitable for multiple pipe diameters.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A quick connector suitable for various pipe diameters includes a connecting pipe, both ends of which are open, and a connecting component for connecting to the pipe to be connected is provided in the middle of the interior of the connecting pipe.

[0007] Both ends of the connecting pipe are fixedly connected to the outer walls of the pipe. The fixed rings have an installation groove inside, and the installation grooves are provided with two sets of fixing components for fixing the position of the pipe.

[0008] The outer wall of the connecting pipe is provided with two sets of symmetrically arranged control components for controlling the fixed state of the pipe.

[0009] In one possible design, the connecting assembly includes a fixed partition that is fixedly connected inside the connecting pipe. The fixed partition has multiple annular grooves on both sides and a water inlet hole in the middle.

[0010] In one possible design, the fixing assembly includes multiple limiting rods fixedly connected to the inner wall of the mounting groove. The multiple limiting rods are arranged in a ring on the inner wall of the mounting groove and divided into multiple groups. The multiple limiting rods are in pairs, and the outer walls of two limiting rods in the same group are slidably fitted with the same rectangular plate. The rectangular plate has a limiting groove inside, and the limiting groove is slidably connected to the limiting rod. Two tension springs are fixedly connected between the inner wall of the mounting groove and one side of the rectangular plate. The tension springs are fitted on the outer walls of the limiting rods. The outer wall of the connecting pipe has multiple rectangular holes, and the rectangular plate slides through the rectangular holes.

[0011] In one possible design, the control component includes a sliding push plate slidably connected to the outer wall of the connecting pipe. A plurality of first connecting rods and a plurality of second connecting rods are fixedly connected to one side of the sliding push plate. A triangular block is fixedly connected to one end of each of the plurality of first connecting rods and the plurality of second connecting rods. The plurality of triangular blocks are used in conjunction with a plurality of rectangular plates.

[0012] In one possible design, a rubber ring is provided inside the annular groove.

[0013] In one possible design, the dimensions of the multiple annular grooves are not the same, and the dimensions of the multiple annular grooves gradually increase from the inside to the outside.

[0014] In one possible design, a clamping plate is fixedly connected to one end of the rectangular plate, and a rubber pad is fixedly connected to one end of the clamping plate.

[0015] In one possible design, the outer wall of the connecting pipe is threaded with a threaded ring, one side of which is rotatably connected to one side of the sliding push plate.

[0016] In this application, when in use, the two pipes to be connected are inserted from both ends of the connecting pipe. At this time, according to the different pipe sizes, multiple annular grooves are pre-made on both sides of the fixed partition to accommodate pipes of different diameters. One end of the pipe is inserted into the appropriate annular groove, and the sealing performance is improved by the sealing ring inside the annular groove.

[0017] At this point, rotating the threaded ring causes it to move on the surface of the connecting pipe, which in turn pushes the sliding push plate to move laterally. The sliding push plate then drives multiple first connecting rods and multiple second connecting rods to move laterally. The first and second connecting rods then drive multiple triangular blocks to move laterally. The inclined surfaces of the triangular blocks abut against one end of the rectangular plate and push the rectangular plate to move. The rectangular plate then drives the clamping plate to move into the connecting pipe and clamps the outer wall of the pipe. Rubber pads enhance friction and sealing. The multiple clamping plates are arranged at different angles and are in two sets, which ensures the stability of the pipe.

[0018] Beneficial effects: Wide applicability: By setting multiple annular grooves of different sizes, this connector can be adapted to pipes of various diameters without the need to replace different models of connectors, which greatly simplifies the construction process and reduces costs.

[0019] Excellent sealing performance: The rubber ring inside the annular groove and the rubber gasket on the clamping plate work together to ensure the sealing performance of the joint, effectively preventing fluid leakage and improving the efficiency and safety of fluid transmission.

[0020] Stable connection performance: By controlling the components to push the clamping plates into the connecting pipe, the outer wall of the pipe is clamped. Multiple clamping plates are arranged at different angles and there are two sets. This design not only enhances the connection strength of the joint, but also ensures the stability of the pipe during the connection process, avoiding safety hazards caused by pipe shaking or falling off.

[0021] Simple operation: The pipe can be fixed and loosened by rotating the threaded ring. The operation is simple and quick, without the need for professional tools or complicated steps, which greatly improves construction efficiency. Attached Figure Description
