Problems solved by technology

However, this type of rolling door needs to be equipped with pin shafts separately, which not only makes the structure of the rolling door complex, which makes the installation process more difficult, but also has a large material processing cost. In addition, due to its complex structure, the service life of each component and each The assembly accuracy between parts cannot be effectively guaranteed, which will lead to a short overall service life

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] As shown in the figure, the present invention provides a rolling door, which includes symmetrically arranged guide rails 1 and a rolling door body 2 arranged between the guide rails 1 and slidingly fitted with the guide rails 1 , the sliding groove of the bending part 3 of the guide rail 1 width d 1 Greater than the chute width d of the straight side part 4 2 , and there is a smooth transition connection between the chute of the bent portion 3 and the chute of the straight portion 4 . The smooth transition referred to above refers to the calculation of the motion of the bending part of the main body of the rolling door to obtain a motion curve that is consistent with the main body of the rolling door, so that a corresponding design is made to match the bending part of the main body of the rolling door. The side of the chute, that is to...

Abstract

The invention discloses a rolling door, which comprises symmetrically arranged guide rails (1) and a rolling door main body (2) arranged between the guide rails (1) and slidingly matched with the guide rails (1), characterized in that the guide rails ( 1) Chute width d of the bending part (3) 1 Greater than the chute width d of the straight edge (4) 2 , and there is a smooth transition connection between the chute of the bent portion (3) and the chute of the straight portion (4). The present invention provides a rolling shutter door with a simple structure so that the installation process is simple and the overall service life of the rolling door is long.

Description

technical field [0001] The invention relates to the technical field of doors, in particular to a rolling door. Background technique [0002] Rolling shutter doors are widely used in various cabinets and house constructions due to their lightness and small footprint. However, the rolling doors of the prior art are mostly connected end to end by a number of rolling door bars and hinged into the main body of the door through pin shafts. Make the main body of the door slide on the guide rail to realize the effect of opening and closing the door. However, this type of rolling door needs to be equipped with pin shafts separately, which not only makes the structure of the rolling door complex, which makes the installation process more difficult, but also has a large material processing cost. In addition, due to its complex structure, the service life of each component and each The assembly accuracy between parts cannot be effectively guaranteed, which will lead to a short overall ...
