Two parallel double-hole ear plates are arranged on the base, and pivot holes on the two double-hole ear plates correspond to each other; Connecting holes and shaft pin holes are respectively arranged on the top; through the pivot holes corresponding to each other on the double-hole lug plate and the pivot pin holes on the pull ears, the pull ears and the base are rotationally connected together with pins. The double-head pull-joint base of the utility model is only composed of a base and two lifting lugs, and has a simple and practical structure, and is particularly convenient to manufacture. The utility model is mainly used as a pull-joint piece for glass curtain walls.

Description

Double pull base

technical field

The utility model relates to a connecting piece, in particular to a glass curtain wall pulling joint.

Background technique

As an important building material, glass has been widely used. The use of glass curtain walls to protect buildings is a major development trend in today's world. Since glass is a brittle material with high hardness, when it is used as a curtain wall of a building, it needs to be connected and fixed with various connectors. The pull connector is an important connector that needs to be used in the installation and construction of the glass curtain wall. Patent document CN1432700A discloses a glass curtain wall elastic claw, and the glass clamping mechanism is connected to the building through elastic mediation. The glass is suspended on the building by springs, and an elastic connection is formed between the glass and the building, which can attenuate the seismic stress transmitted to the glass by the building, and improve the anti-seismic performance and impact resistance of the glass.

Contents of the invention

The purpose of the utility model is to provide a glass curtain wall pull-joint piece with simple and practical structure, convenient manufacture and low cost, which is suitable for installing a small-sized whole piece of glass canopy. For realizing this purpose, the technical scheme that the utility model takes is:

Including the base and the lug, there are two parallel double-hole lugs on the base, and the holes on the two double-hole lugs correspond to each other; the lugs are respectively provided with connecting holes and shaft pin holes; through the double holes The holes corresponding to each other on the lug plate and the shaft pin holes on the pull lug are used to rotate and connect the pull lug and the base together with pins.

The double-head pull-joint base described in the technical solution of the utility model is only composed of a base and two lifting lugs, a total of three parts, the structure is simple and practical, the manufacture is particularly convenient, and the cost is low.

Detailed ways

It includes a base 1 and two pull ears 2 . Two parallel double-hole ear plates 3 are provided on the base 1 , two sets of pivot holes 4 corresponding to each other are provided on the two double-hole ear plates 3 , and two base connection holes 7 are also provided on the base 1 . The base 1 is an oval flat plate, and the two double-hole ear plates 3 are arranged on both sides of the long axis of the oval base 1 and are parallel to the long axis of the oval base 1. The two base connecting holes 7 It is arranged at both ends of the major axis of the oval base 1 .

Connecting holes 5 are respectively provided on the two lugs 2, and pivot pin holes 6 are set at the bottom of the lugs 2; Two sets of pivot holes 4 corresponding to each other are set, and the two pull ears 2 are movably connected with the base 1 by screws, and the pull ears can rotate around the connecting shaft. Both lugs 2 are right-angled trapezoidal flat plates, pivot pin holes 6 are respectively arranged on the long bottom side of the right-angled trapezoidal lugs 2, and connecting holes 5 are respectively arranged on the side near the short bottom of the right-angled trapezoidal lugs 2.

When in use, the double-head pull-joint base is fixed on the wall through the two base connection holes 7, and the pull rod for hanging the glass is pulled through the connection hole 5 on the pull ear 2.
