Description

[0001] The present invention relates to a pipe press tool having a three-segment structure,

The present invention relates to a clamping fastener for a pipe having a trichotomous structure, and more particularly to a clamping fastener for a pipe having a three-stage clamp structure having both sides and a central portion to which a force is directly transmitted by a tool, Since the protrusion is formed, the force applied by the tool is distributed in a balanced manner, uniform force is applied to the pipe connection portion, and the pipe can be firmly connected, as well as the breakage of the clamp can be prevented.

Generally, the metal pipes to be installed for water pipes and indoor pipes of buildings are thin and made of stainless steel, so that it is impossible to connect them by thread cutting or welding. This is because the metal structure may be changed by heat generated by welding and corrosion resistance may be caused by thermal stress. Therefore, such a metal tube is usually fastened by a method of mechanically compressing a pipe-pipe joint using a pipe-clamped fastener.

In the conventional pipe clamping fastener, a plurality of arc-shaped clamping members are hingedly connected to each other, a plurality of pressing members are provided on the periphery of the clamping member, and the pressing member is deformed into a ring shape together with the rotation of the clamping member. When the end of the clamp member is pressed using a tool in a state where the pipe squeezing member is positioned so that the pressure member is wrapped around the pipe connection site requiring connection, the pipe connection site is squeezed and deformed according to the shape of the pressure member.

However, in the conventional pipe clamping fastener, since the clamping members are divided into a plurality of clamping members, the pressing force is not uniformly dispersed when the tool is pressed by the tool, so that the pipe connecting portion is not completely sealed and the connecting force is lowered. Further, since the clamp members are not received uniform force, the connection parts are loosened and broken. In addition, since the structure is relatively complicated, it is complicated to manufacture and heavy in weight, resulting in poor work efficiency.
