CN2446269Y - Connector of iron shutter - Google Patents

Abstract

The utility model discloses a connector of an iron shutter. The utility model has the main structure that a pin joint casing tube 111 is assembled between a connector body 11 and a side cover 12 to combine the connector body 11 and the side cover 12 into a whole body; the pin joint casing tube 111 is provided with a through hole 112 penetrated by a main horizontal tube 2 of the iron shutter so as to increase contact area between the connector body 11 and the side cover 12 and not damage the main horizontal tube; because slippage is not generated between the connector body 11 and the side cover 12, noise is reduced; the utility model is used for conveniently assembling the iron shutter.

Description

The connecting piece of iron rolling door

The utility model relates to a kind of iron rolling door, particularly a kind of connector of iron rolling door.

General iron rolling door commonly used uses connecting piece 3 as Fig. 6, shown in Figure 7, this connecting piece 3 is to become two double left sides with metal stamping, right connecting piece 31, at this on a left side, right connecting piece 31 two ends form long slightly pivoted hole 311, need during use two left sides, right connecting piece 31 merges use, to improve its indecency outward appearance, by every group of left side, connecting piece 3 after right connecting piece 31 combinations forms long pivoted hole 311, to increase and the contact area of 2 of iron rolling door master transverse tubes, reduction is to the injury of main transverse tube 2, though 3 designs of this kind connecting piece can reduce the wearing and tearing to main transverse tube 2, main transverse tube 2 can be made with hollow metal tube, but this kind connecting piece has following shortcoming:

1, this kind connector 3 forms for left and right connecting piece 31 and group, for individual from the independent but not design that integrally combines, so when iron rolling door scrolling, collision is rocked in generation between left and right connector, and sends great noise;

2, left and right connector 31 is processed respectively, and the pitch-row of its pivoted hole 311 or concentricity can't be in full accord, also be one of reason that produces noise, and the intensity of connecting piece is disperseed;

Need when 3, using left and right connecting piece composite assembly, more time-consuming;

Low, the easy to assembly iron rolling door connecting piece of noise when the purpose of this utility model provides a kind of use.

For reaching above-mentioned purpose, the utility model by the following technical solutions:

The utility model includes a connecting piece body and a side cover, wherein, connecting piece body two ends are provided with long pivot joint sleeve pipe, two articulate sleeve pipe is provided with through hole, connecting piece body periphery is provided with flanging, the corresponding connecting piece body of side cover periphery flanging also is provided with flanging, the side cover two ends are provided with the perforation that articulates the sleeve pipe concentric with connecting piece body two, two of connecting piece body articulates two perforation that sleeve pipe passes side cover, the pivot joint sleeve pipe is positioned at the head end punching press expansion in the side cover outside, connecting piece body and side cover is combined into one, during use, the main transverse tube of iron rolling door passes the through hole that the connecting piece body articulates sleeve pipe, increase the contact area with main transverse tube, do not damaged main transverse tube, during iron rolling door scrolling, can not produce between connecting piece body and the side cover and rock collision, can not produce noise.

The utility model will be further described below in conjunction with drawings and Examples:
