Rapid pipe connecting device

Abstract

The invention discloses a rapid pipe connecting device which comprises a tubular shell. The tubular shell is composed of two major diameter parts at two ends and a thin diameter part at a middle part; wherein a limiting bulge loop is arranged at the middle part of an inner cylindrical surface of the thin diameter part, cambered surface steps are formed at a position where the two major diameter parts at the two ends are combined with the thin diameter part, clamping assemblies are respectively arranged in the two major diameter parts of the tubular shell, a seal ring is arranged between the steps and the clamping assemblies, each major diameter part of the tubular shell comprises two sections of inner diameters arranged from inside to outside and from small to large, an internal thread is arranged at a larger inner diameter, and the clamping assemblies are provided with a pressing cap, a movable sleeve and an elastic clamping head in sequence from outside to inside. The rapid pipe connecting device has the beneficial effects that a sealing effect is good, a structure is reasonable and convenient to disassemble, and the device can be installed directly with hands and can be disassembled with special tools, so that the device is simple to disassemble, is time-saving and labor-saving, is free from limitation of an installation position, is light in weight, low in cost and wide in application range; and moreover, the rapid pipe connecting device is suitable for rapid connection between two pipelines, or between a pipeline and a valve.

Description

technical field [0001] The invention relates to a connecting device for pipelines, in particular to a quick pipe connecting device. Background technique [0002] Due to reasons such as manufacturing and transportation, the length of the pipeline is always standard, and if the pipeline is connected, a large number of pipe joints are required. At present, the structure of the commonly used traditional pipe connection device is very simple. Only internal threads are processed in each through hole of the pipe connection device, and the pipes or valves are connected together through the external thread connection with the end of the pipe or valve. This traditional pipe joint is cheap in cost and simple in process, but in order to ensure its sealing during construction, it is necessary to wrap a raw material tape or an annular rubber sealing ring on the external thread at the end of the pipe or valve, and then screw the pipe or valve with a wrench. Put it into the pipe connecting...

Problems solved by technology

This construction method is troublesome and slow, and tools are needed for assembly and disassembly, which is very inconvenient

In order to solve the above problems, people have invented quick pipe joints. There are many structures of quick pipe joints. The sealing effect of the pipe connection is not very good, and water leakage may occur, causing losses and affecting production and life. Some snap-fit ​​components for quick pipe connections have many accessories, complex structures, troublesome installation, and high manufacturing costs.
