Title:
TUBE CONNECTOR CLAMPING TOOL
Document Type and Number:
WIPO Patent Application WO/2017/188717
Kind Code:
A1
Abstract:
A tube connector clamping tool according to the present invention comprises: a body comprising a pair of support portions, first ends of which are connected to each other by a shaft pin, and a pair of fastening portions formed to be able to conduct fastening operations on the upper portions of the support portions; and clamping members, each of which is coupled to an end of each of the pair of fastening portions. A side surface of the clamping member and a side surface of the body face each other and are elastically supported by an elastic member. A clamping member back surface of the clamping member and a guide surface of a fastening portion, which faces and abuts the clamping member back surface, are configured as arc-shaped flat surfaces, respectively, such that a line contact portion is formed in the process of clamping between the clamping member back surface and the guide surface, which face and abut each other. In addition, a wedge-shaped space is formed between the clamping member back surface and the guide surface, which face and abut each other, such that the distance of spacing increases gradually toward the rear side of the line contact portion in the process of clamping. Accordingly, the present invention can minimize slip friction occurring between a movable jaw and a socket portion and can also minimize a bulge formed by protrusion of the socket portion during clamping.
