A push-pull combination door

Abstract

The invention discloses a sliding combination door. The sliding combination door comprises a door body, an upper guide rail, a lower guide rail and a door body transmission mechanism; the upper guide rail and the lower guide rail are arranged in parallel and are of rectangular pipe structures; the door body transmission mechanism comprises a driving device and moving mechanisms which are arranged in the upper guide rail and the lower guide rail; a chain wheel is arranged on the output shaft of the driving device; each moving mechanism comprises a plurality of moving units which are hinged together in proper sequence; each moving unit comprise a load-bearing wheel assembly and a guide wheel assembly, and a load-bearing wheel of each load-bearing wheel assembly is perpendicular to a guide wheel of each guide wheel assembly; the moving mechanism arranged in the upper guide rail is connected with the upper end of the door body, an opening type structure is arranged on the upper guide rail, and the chain wheel of the driving device is engaged with the moving mechanism at the part of the opening type structure in a transmission mode; and the moving mechanism arranged in the lower guide rail is perpendicularly connected with the lower end of the door body through a buffering mechanism. According to the sliding combination door, the structure is simple, friction resistance is small, opening and closing of the door body is light and convenient, running is smooth, derailment or sticking is prevented, and the service life is long.

Description

technical field [0001] The invention relates to a push-pull combination door, in particular to a push-pull combination door for workshops and warehouses. Background technique [0002] At present, rolling shutter doors are mostly used in workshops or warehouses, and the speed of the left and right rolling shutters is inconsistent, which can easily cause the rolling shutters to fall out of the groove or get stuck. At the same time, the rolling shutters have a short service life and high maintenance costs, especially for wide-width workshops. There are also those who use sliding doors at present. When using sliding doors, the lower load-bearing wheels are often used. The friction resistance is large, the structure of the electric drive system is complicated, and the sealing performance is poor. , The upper track of the sliding door is made of I-beam, which is easy to cause derailment, and the airtightness is poor, and the structural parts are easy to rust and age.

[0002] At present, rolling shutter doors are mostly used in workshops or warehouses, and the speed of the left and right rolling shutters is inconsistent, which can easily cause the rolling shutters to be detached or stuck. At the same time, the service life of the rolling shutters is short and the maintenance cost is high, especially for wide workshops.

There are also those who use sliding doors at present. When using sliding doors, the lower load-bearing wheels are often used. The friction resistance is large, the structure of the electric drive system is complicated, and the sealing performance is poor. , The upper track of the sliding door is made of I-beam, which is easy to cause derailment, and the airtightness is poor, and the structural parts are easy to rust and age
