Pipe clamping device

Abstract

A wireless Internet phone is provided to offer mobility through a wireless LAN-based VoIP service by installing a base machine to implement a base station function and a handset to execute phone calls through the Internet. A wireless Internet phone consists of a handset(1), a base machine(2), and an Internet phone base station(3). The handset(1), communicating data with the base machine(2) by wireless, connects a user to the other side through the Internet. The base machine(2), if packet data containing a phone number and ID information are received from the handset(1), transmits the packet data to the Internet phone base station(3) through the Internet. The Internet phone base station(3), if the packet data are received from the base machine(2), executes authentication for the user of the handset(1) by using the ID contained in the packet data. As a result of authentication, in case that it is judged that the user of the handset(1) is a service subscriber, the Internet phone base station(3) makes a call to the phone number contained in the packet data.

Description

technical field [0001] The invention relates to a pipe clamping device, in particular to a pipe clamping device which generates greater clamping force through the elastic deformation of the clamping ring when the bolt is tightened. Background technique [0002] Usually, a clamping device is widely used when connecting a pipeline to another pipeline. This clamping device firmly clamps and fixes the pipelines to connect the two pipelines to prevent liquid leakage in the pipelines. [0003] A conventional pipe clamp device includes a clamping ring, which is located between a concave hoop and a convex hoop, and the two hoops are fastened by bolts; and the clamping ring is in the shape of a metal ring, and the clamping ring The clamping edge clamps the outer circumference of the pipeline to prevent the pipeline from coming out; and a sealing ring seals the gap between the clamped pipelines. [0004] Here, the clamping ring is pressed against the pipeline by strong force, and the...

AI Technical Summary

Problems solved by technology

Therefore, the shape of the pipe clamp device needs to be enlarged, and its manufacturing cost is therefore increased.

[0009] At the same time, because the conventional pipe clamping device only adopts one clamping ring, the clamping force to the pipe cannot be increased as expected

When designing the pipe clamp device, it is also impossible to reduce the outer diameter of the concave and convex hoops

As a result, its pipe holding power is not great

[0010] Moreover, because the conventional pipe clamp device has a gap space for elastic deformation after installation, part of the clamping force will be lost when elastic deformation occurs after installation, thus reducing the durability and reliability of product performance
