Description

Technical Field

[0001] This utility model relates to the field of pipe fitting technology, specifically a compression 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 structure should ideally employ 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. Pipe fittings come in many types, commonly categorized into rigid pipe fittings and flexible pipe fittings. Based on the connection method between the fitting and the pipe, rigid pipe fittings include flared, compression, and welded types, while flexible pipe fittings are mainly crimp-type hose fittings. The connection methods between pipes and fittings in hydraulic systems also differ; the pipe screw-in end uses a connecting thread. Tapered threads, relying on their cone-shaped tightening and sealing with materials such as PTFE, are mainly used in medium- and low-pressure hydraulic systems. Fine-pitch threads offer excellent sealing and are frequently used in high-pressure systems. However, they require the use of combination washers or O-rings for end-face sealing, and sometimes copper washers are also used. They are well-suited for connecting pipes with thicker walls. The main components are the connector body, connecting pipe, and nut. In use, the connector body is embedded 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. Extruded pipes are pipes manufactured using extrusion molding processes in the metallurgical field, possessing core characteristics such as high strength, high temperature resistance, corrosion resistance, wear resistance, and aging resistance. Their production process ensures uniform strength and dimensional stability through precision machining, and the raw materials meet green manufacturing standards. In the chemical industry, they are used in chemical transportation systems; in the construction industry, in water supply and drainage and hot water pipelines; in the automotive industry, in fuel and cooling systems; and in the energy industry, in high-temperature pipelines of thermal power plants. Research has found that extruded pipes have superior surface quality and a more stable microstructure compared to products manufactured using skew rolling processes, thus necessitating an extruded pipe fitting.

[0003] Existing pipe fittings require through-connection when connecting pipes, which can easily damage the pipes and reduce the safety of the pipe connection. They also cannot stably clamp and fix the pipes, making it easy for the pipes to drift and fall off during the connection, thus reducing the stability of the pipe connection. Utility Model Content

[0004] The purpose of this utility model is to provide a compression-type pipe joint to solve the problems mentioned in the background art. Existing pipe joints require through-connection when connecting pipes, which can easily damage the pipes and reduce the safety of the pipe connection. They also cannot stably clamp and fix the pipes, which can easily cause the pipes to drift and fall off during connection, thus reducing the stability of the pipe connection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a compression-type pipe connector, comprising a lower mounting tube made of aluminum, a lower placement groove being provided through the interior of the lower mounting tube, and threaded holes being provided around the exterior of the lower placement groove, a lower compression disc being movably mounted on the top of the lower mounting tube, threaded holes being provided around the interior of the lower compression disc, a lower compression sleeve being fixedly mounted on the bottom of the lower compression disc, and a lower disc retaining sleeve being fixedly mounted on the top of the lower compression disc.

[0006] Preferably, a lower pipe is movably installed inside the lower placement groove, and the lower pipe is made of rubber.

[0007] Preferably, the lower extrusion disc is made of aluminum, and an upper extrusion disc is movably mounted on the top of the lower extrusion disc.

[0008] Preferably, an upper extrusion sleeve is fixedly installed on the top of the upper extrusion disc, and the interior of the upper extrusion disc is provided with threaded holes around it. An upper mounting tube is movably installed on the top of the upper extrusion disc.

[0009] Preferably, the upper plate threaded hole has an upper plate groove that extends through it, and the upper plate groove is semi-cylindrical in shape.

[0010] Preferably, the upper mounting tube has an upper placement groove through which it passes, and an upper pipe is movably installed inside the upper placement groove. The upper placement groove is surrounded by upper threaded holes.

[0011] Preferably, each of the upper threaded holes is movably fitted with a fastening screw, and each fastening screw is threaded with a fastening washer, with fastening nuts threaded at both ends of the fastening washer.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This type of extrusion pipe fitting allows for flexible placement of the lower pipe during daily use. The lower installation pipe, made of aluminum, has a through-hole for the lower placement groove, allowing the lower pipe to be moved and placed. The fastening screw can then be moved through the threaded hole. This flexible placement and insertion method makes it less likely to damage the pipe and improves the safety of the pipe connection.

[0013] This type of extrusion pipe fitting, during daily use, has its fastening threads passing through the threaded hole inside the lower extrusion disc, allowing the lower extrusion disc to move and be placed on top of the lower installation pipe. Then, the lower extrusion sleeve is used to extrude and fasten the lower pipe inside the lower placement groove, which can stably clamp and fix the pipe, making it less likely for the pipe to drift or fall off during pipe connection, thereby improving the stability of the pipe connection.
