Hardware connecting rod capable of being used for electric telescopic door

Abstract

The invention discloses a metal connecting rod that can be used for an electric retractable door. One end of connecting rod one and connecting rod two of the hardware connecting rod has a vertically symmetrical structure, and the connecting rod three and connecting rod four are also vertically symmetrical. Straight symmetric mechanism, one end of the connecting rod one is provided with a groove, the two ends of the groove reach the outer end surface of the connecting rod one to have a through hole one, one end of the connecting rod two is stuck in the groove and The end of the connecting rod 2 is provided with a through hole 2, and a rotating shaft passes through the through hole 1 and the through hole 2 in turn, and the connecting rod 1 and the connecting rod 2 are rotationally connected through the through hole 1, the through hole 2 and the rotating shaft; The third connecting rod and the fourth connecting rod are flexibly connected by the same mechanism as the first connecting rod and the second connecting rod. Coated with anti-corrosion coating. The telescoping door of the present invention is easy to open and gives corrosion protection.

Description

technical field [0001] The invention relates to the technical field of electric telescopic doors, in particular to a hardware connecting rod that can be used for electric telescopic doors. Background technique [0002] At present, the electric telescopic doors used in the fields of enterprises, governments, villas, etc. are basically assembled into various structures through hardware connecting rods, and then the electric telescopic doors are opened and closed through the main shaft on the hardware connecting rods. However, due to the unreasonable structure of this hardware connecting rod, the service life of the electric telescopic door is greatly reduced. Specifically, the hardware connecting rod is mainly assembled by hardware fasteners, and hardware fasteners are often assembled through multiple Such a structure is easily damaged, and the shaft sleeve on the metal connecting rod is also directly welded. This structure leads to poor stability of the metal connecting rod a...

[0002] At present, the electric telescopic doors used in the fields of enterprises, governments, villas, etc. are basically assembled into various structures through hardware connecting rods, and then the electric telescopic doors are opened and closed through the main shaft on the hardware connecting rods. However, due to the unreasonable structure of this kind of hardware connecting rod, the service life of the electric telescopic door is greatly reduced. This structure is easily damaged. In addition, the shaft sleeve on the metal connecting rod is also directly welded. This structure leads to poor stability of the metal connecting rod and is easy to deform. , if the hardware fastener is welded by multiple hardware parts, it will increase the difficulty of processing and manufacturing, especially for the current situation of high domestic raw material and labor prices, such defects are particularly prominent, and the metal connecting rod is easy to be corroded
