Double leaf electric translational cold-storage door

Abstract

The invention relates to a two-swing electric translatory cold storage door with a simple structure, low cost, small noise, environmental protection and short production period. The door comprises a guide way, wherein two ends of the guide way are fixed with limit plugs; the guide way is connected with a driving swing and a driven swing through a road wheel support assembly from the inside; the driving swing is fixed with a motor reducer; a motor output shaft of the motor reducer is fixed with a driver gear; the driver gear is in driving connection with a driving rack; the driving rack is fixed on a bracket; the driving rack is fixed with a wirerope mainspring disc; the wirerope mainspring disc is wound with a closed wirerope; the other end of the closed wirerope is fixed on the driven swing; the driven swing which is positioned on the left side of a connection point between the closed wirerope and the driven swing is fixed with an open wirerope; the other end of the open wirerope is fixed on the driving swing; the open wirerope is in rolling connecting with a fixed pulley; the fixed pulley is fixed on the left side of the driven swing; and a rotation diameter of the wirerope mainspring disc is two times that a rotation diameter of the driving rack.

Description

technical field [0001] The invention relates to a cold storage door, in particular to a double-leaf electric translational cold storage door. Background technique [0002] At present, at home and abroad, the transmission device of the double-leaf translational thermal insulation electric door has chain sprocket transmission, rack and pinion transmission and equivalent belt transmission, etc., and is fixed on the wall with two sets of transmission devices, each driving a translational thermal insulation door. , This type of transmission has the disadvantages of complex structure, high cost, high noise, not environmental protection, and long production cycle. Contents of the invention [0003] The object of the present invention is to provide a double-leaf electric translational cold storage door with simple structure, low cost, low noise, environmental protection and short production cycle. [0004] To achieve the above object, the technical solution adopted in the present...
