Abstract

The utility model relates to a connecting piece of section material, and the connecting piece comprises a casing body (3) and a tension bar main body (7) arranged in the inner cavity of the casing body (3). A radial convex raised head (1) is arranged at one end part of the tension bar main body (7), the raised head of a tension bar is positioned on the outer side of one end of the casing body (3), and a groove (13) of the tension bar is opened on the tension bar main body (7) arranged in the casing body (3). An eccentric wheel (5) is arranged in the groove (13) of the tension bar, an eccentric wheel axle (6) is arranged at the position deviated from the centre of the circle of the eccentric wheel (5), the eccentric wheel axle (6) is positioned in the axle hole of the eccentric wheel on the casing body (3), and a spring (9) is arranged at the top part of the other end of the tension bar main body (7). When the eccentric wheel axle is rotated, the eccentric wheel can drive the tension bar main body to make the axial motion, thereby the raised head of the tension bar can be pulled, so that the raised head of the tension bar drives one of the section materials to move, and the operation is simple.

Description

The section bar link

Technical field

The utility model relates to a kind of section bar link, particularly orthogonal two links that section bar is used.

Background technique

In the prior art, orthogonal section bar need connect with link in the joint, a section bar is wherein held with the hook on the link, link is fixed on another root section bar, turn eccentric wheel on the link with specific screw-driver, make hook tension section bar, the complex structure of this link, manufacture cost is big, need be on a section bar perforate with fixed connecting piece.

Summary of the invention

The purpose of this utility model is to provide a kind of section bar link simple in structure.

The technical solution of the utility model is: a kind of section bar link, comprise housing, be arranged at the pull bar body in the inner chamber of described housing, one end of described pull bar body is provided with the pull bar plush copper of radial protrusion, this pull bar plush copper is positioned at the end outside of described housing, have the pull bar groove on the described pull bar body that is positioned at housing, be provided with eccentric wheel in this pull bar groove, described eccentric position of departing from the center of circle is provided with eccentric shaft, this eccentric shaft is positioned at the eccentric wheel axis hole on the housing, and there is spring on the top, the other end of described pull bar body.

The utility model compared with prior art has following advantage:

When rotating eccentric shaft, eccentric wheel can drive the pull bar body and do axial motion, then spurs the pull bar plush copper, and a section bar that makes the pull bar plush copper drive wherein moves, and is simple to operate, easy to use.
