Description

Technical Field

[0001] This utility model relates to the field of pipe fitting technology, specifically a quick-connect pipe fitting. Background Technology

[0002] Pipe fittings are connecting tools between pipes, serving as detachable connection points between components and pipes. They play an indispensable role in pipe fittings and are one of the two main components of hydraulic pipelines. Pipe fittings are used for straight connections in instruments, etc., and the connection methods include socket welding or threaded connections. They are mainly used in small-diameter, low-pressure pipelines, in areas requiring frequent assembly and disassembly, or for final adjustments in pipelines using threaded fittings. The preferred structural form is a metal-to-metal contact sealing structure; gasket sealing structures are typically used in pipelines transporting water, oil, air, etc., and are made of malleable cast iron. In addition, usage requirements and price are also factors to consider when selecting pipe fittings. There are many types of pipe fittings, commonly divided into rigid pipe fittings and flexible pipe fittings. If classified according to the connection method between the pipe fitting and the pipeline, rigid pipe fittings include flared, compression, and welded types, while flexible pipe fittings are mainly crimped hose fittings. The connection methods between pipes and pipe fittings in hydraulic systems also differ; the screw-in end of the pipe uses a connecting thread. Tapered threads, tightening with their cone-shaped structure and sealing with materials like PTFE, are primarily used in low- to medium-pressure hydraulic systems. Fine threads offer excellent sealing and are frequently used in high-pressure systems, but require combination washers or O-rings for end-face sealing; sometimes copper washers are also used. They are best suited for connecting thicker-walled pipes. Their main components include a connector body, a connecting pipe, and a nut. In use, the connector body is inserted into the target, and the aforementioned washers are used to seal the end face. A rubber seal is used between the connector body and the connecting pipe; sometimes a spherical seal is also used. Four-way flexible hose fittings are divided into quick-connect and non-quick-connect types. Quick-connect four-way flexible hose fittings are convenient and efficient, achieving rapid installation. However, the structural design of commonly used quick-connect four-way flexible hose fittings is not ideal, making it difficult to truly achieve rapid installation, resulting in inconvenience and a narrower application range. In addition, the interfaces in the existing quick-connect four-way hose fittings face four different directions. When two interfaces are needed for one direction, it is inconvenient to use. Therefore, a quick-connect hose fitting is needed.

[0003] Existing pipe fittings are prone to falling off during connection, which reduces the waterproofness of the pipe fittings to the conduit connection. They also cannot be easily snapped into place, resulting in low efficiency during pipe fitting connection and thus reducing the ease of pipe fitting assembly. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-connect pipe fitting to solve the problems mentioned in the background art, such as the existing pipe fittings being prone to falling off during connection, which reduces the waterproofness of the pipe fitting to the conduit connection, and the inability to easily snap the conduit fitting into place, resulting in low efficiency in connecting the conduit fitting and thus reducing the ease of pipe fitting assembly.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a quick-installation pipe fitting, comprising a snap-fit ​​sleeve, wherein a snap-fit ​​inner groove is provided through the outside of the snap-fit ​​sleeve, and snap-fit ​​half sleeves are movably installed inside the snap-fit ​​inner groove, wherein snap-fit ​​blocks are fixedly installed at both ends of the snap-fit ​​half sleeves, and snap-fit ​​holes are provided through the inside of the snap-fit ​​blocks.

[0006] Preferably, the inner sleeve of the snap-fit ​​sleeve is movably fitted with a pipe wrapping inner layer, the inner sleeve of the pipe wrapping inner layer is movably fitted with a pipe body, the outer sleeve of the pipe wrapping inner layer is movably fitted with a right sleeve inner layer, and one side of the right sleeve inner layer is movably fitted with a left sleeve inner layer.

[0007] Preferably, a middle layer of tube wrapping is fixedly sleeved outside the inner layer of tube wrapping, and an outer layer of tube wrapping is fixedly sleeved outside the middle layer of tube wrapping.

[0008] Preferably, the outer fixing sleeve of the right sleeve inner layer is provided with a right sleeve middle layer, the outer fixing sleeve of the right sleeve middle layer is provided with a right sleeve outer layer, and the outer fixing sleeve of the right sleeve outer layer is provided with a right sleeve waterproof layer.

[0009] Preferably, the right sleeve waterproof layer is externally movably sleeved with a right fastening sleeve, and the right fastening sleeve is externally fixedly sleeved with a right waterproof sleeve.

[0010] Preferably, the outer fixing sleeve of the left inner sleeve layer is provided with a left middle sleeve layer, the outer fixing sleeve of the left middle sleeve layer is provided with a left outer sleeve layer, and the outer fixing sleeve of the left outer sleeve layer is provided with a left waterproof layer.

[0011] Preferably, the left sleeve waterproof layer is movably sleeved with a left fastening sleeve, and the left fastening sleeve is fixedly sleeved with a left waterproof sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This quick-connect pipe fitting uses a snap-fit ​​sleeve to wrap around the inner layer of the pipe and the conduit during daily use. The snap-fit ​​sleeve has a snap-fit ​​groove around its outer side, which makes the pipe fitting less likely to fall off during connection, thus improving the waterproof performance of the pipe fitting for the conduit connection.

[0013] This quick-connect pipe fitting, during daily use, has two snap-fit ​​half-sleeves that are movably snapped onto the outside of the snap-fit ​​inner groove. Then, the two snap-fit ​​half-sleeves are movably closed by the snap-fit ​​hole inside the snap-fit ​​block. This allows for convenient snap-fit ​​connection of the conduit fitting and is highly efficient in connecting conduit fittings, thereby improving the ease of assembly of the pipe fitting.
