Abstract

The utility model relates to the door technical field, particularly to a rolling door strip. The door strip comprises a door strip body. An inwardly concave arc-shaped plate and a hinged shaft are arranged on the right part of the door strip body; the arc-shaped plate has the same axis as the hinged shaft; the bottom of the arc-shaped plate is bent upwards and is fixed to the hinged shaft; a hinged groove is formed between the hinged shaft and the arc-shaped plate; a hinged plate which is hinged on the hinged groove in a matching manner is arranged on the left part of the door strip; and the hinged plate arched outwards so as to form an arc shape. The hinged plates of the utility model can be conveniently inserted in the hinged grooves formed between adjacent rolling door strips and hinged with the hinged shafts so as to rotate freely around adjacent rolling door strips, so that the installation of adjacent rolling strips is facilitated. Furthermore, the door strip body is a hollow structure and provided with a flat plate arranged on the top part and a curved plate arranged on the bottom. Therefore, the rolling door strip not only saves the material but also possesses higher mechanical strength, and has the advantages of long service life, elegance, and convenient opening and closing.

Description

The rolling door bar

Technical field:

The utility model relates to the gate technique field, particularly a kind of rolling door bar.

Background technology:

Rolling door is convenient owing to light, switch, the reason such as little that takes up room, and is widely used on the furniture such as file cabinet, kitchen cabinet, wardrobe.Existing rolling door is fitted together side by side by many rolling door bars and forms, the rolling door bar is dull and stereotyped, dull and stereotyped two ends, the left and right sides respectively are provided with hollow articulated column, the hollow articulated column of adjacent two rolling door bars is hinged by bearing pin, make and can rotate mutually between the rolling door bar, but this rolling door bar need set bearing pin in addition, install inconvenient, mechanical strength is low, and application life is short, and is not attractive in appearance.

The utility model content:

The purpose of this utility model is to provide a kind of rolling door bar of being convenient to install at the deficiencies in the prior art.

For achieving the above object, the utility model adopts following technical scheme:

The rolling door bar, it includes a bar body, door bar body is a hollow-core construction, its top is dull and stereotyped, the bottom is bent template, right part is provided with circular arc plate and the jointed shaft that caves inward, circular arc plate and jointed shaft concentric, and fixedly connected with jointed shaft in the bottom of circular arc plate upwards bending, form hinged groove between jointed shaft and the circular arc plate, the left part of door bar body is provided with and the articulated slab that is used for the hinged groove coordination hinge, and articulated slab is the circular arc that outwards arches upward, dull and stereotypedly be connected by arc with the right part of bent template, left part connects by articulated slab.

The middle part of described bent template raises up into lug boss, and lug boss is connected with dull and stereotyped by reinforcing rib.

Described jointed shaft is a hollow section.

The utility model beneficial effect is: the utility model includes a right part of bar body door bar body and is provided with circular arc plate and the jointed shaft that caves inward, circular arc plate and jointed shaft concentric, and fixedly connected with jointed shaft in the bottom of circular arc plate upwards bending, form hinged groove between jointed shaft and the circular arc plate, the left part of door bar body is provided with and the articulated slab that is used for the hinged groove coordination hinge, articulated slab is the circular arc that outwards arches upward, dull and stereotypedly be connected by arc with the right part of bent template, left part connects by articulated slab, the articulated slab of the utility model rolling door bar can plug in the hinged groove of adjacent rolling door bar hinged with jointed shaft easily, make rolling door bar of the present utility model freely to rotate around the jointed shaft of adjacent rolling door bar, be convenient to the installation between the rolling door bar, and door bar body is a hollow-core construction, its top is dull and stereotyped, the bottom is bent template, makes the rolling door bar have higher mechanical strength again when saving material, has long service life, attractive in appearance, switch is characteristics easily.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a sectional view of the present utility model;

Fig. 3 is user mode figure of the present utility model.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is further described, see Fig. 1-3, the rolling door bar, it includes a bar body 1, door bar body 1 is a hollow-core construction, its top is dull and stereotyped 2, the bottom is bent template 3, right part is provided with circular arc plate 4 and the jointed shaft 5 that caves inward, jointed shaft 5 is a hollow section, circular arc plate 4 and jointed shaft 5 concentrics, and the bottom of circular arc plate 4 upwards bending fixedly connected formation hinged groove 6 between jointed shaft 5 and the circular arc plate 4 with jointed shaft 5, the left part of door bar body 1 is provided with and the articulated slab 7 that is used for hinged groove 6 coordination hinges, articulated slab 7 is the circular arc that outwards arches upward, and dull and stereotyped 2 are connected by arc 4 with the right part of bent template 3, and left part passes through articulated slab 7 connections.

The middle part of bent template 3 raises up into lug boss 8, and lug boss 8 is connected with dull and stereotyped 2 by reinforcing rib 9, and lug boss 8 and reinforcing rib 9 have strengthened the mechanical strength of the utility model rolling door bar.

The articulated slab 7 of the utility model rolling door bar can plug in the hinged groove 6 of adjacent rolling door bar hinged with jointed shaft 5 easily, make rolling door bar of the present utility model freely to rotate around the jointed shaft 5 of adjacent rolling door bar, be convenient to the installation between the rolling door bar, and door bar body 1 is a hollow-core construction, its top is dull and stereotyped 2, the bottom be bent template 3, makes the rolling door bar have higher mechanical strength in saving again in the material, has long service life, attractive in appearance, switch characteristics easily.

The above only is a better embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
