Lifting transmission structure of lifting door

Abstract

The invention relates to a door leaf structure of an entry door, in particular to a lifting transmission structure of a lifting door. The structure comprises a mounting plate, and the two sides of the mounting plate comprise vertical rolled edges. A motor is mounted at the bottom of the rolled edge on one side and connected with a gearbox, and the gearbox is connected with a transfer belt wheel through a belt. An upper belt wheel is arranged on the upper portion of the mounting plate, the upper belt wheel and the transfer belt wheel are connected through a main transmission belt, and a fixed block is arranged on the main transmission belt. According to the lifting transmission structure of the lifting door, the transfer belt wheel is arranged beside the motor and the gearbox, the perpendicularity of the main belt can be effectively adjusted by adjusting the horizontal position of the transfer belt wheel, and adaptability to door leaves of multiple specifications is effectively achieved. Only the position of the transfer belt wheel and the length of a secondary belt need to be controlled during construction, the positions of the motor, the gearbox, the upper belt wheel and other main components are not specifically required, and good flexibility is achieved.

Description

technical field [0001] The invention relates to a door leaf structure of an entrance door, in particular to a lifting and lowering transmission structure of a lifting door. Background technique [0002] Portal door is the type of door leaf that every family residence must use. In terms of material, there are generally wooden doors, metal doors and other types. Among them, metal doors occupy a large share in the entrance door due to their good anti-theft effect. There is a special door structure in the existing metal entrance door. There is a half movable door leaf on the upper or lower part of the door leaf. The half movable door leaf can be driven up and down by the driving mechanism, so that the half door leaf can be closed and closed. Switch between open and open, so as to adjust the indoor ventilation. In the existing lifting transmission structure, the motor drives the belt or chain to drive a fixed block up and down. The lifting door is directly or indirectly fixed on ...

[0002] Portal door is the type of door leaf that every family residence must use. In terms of material, there are generally wooden doors, metal doors and other types. Among them, metal doors occupy a large share in the entrance door due to their good anti-theft effect. There is a special door structure in the existing metal entrance door. There is a half movable door leaf on the upper or lower part of the door leaf. The half movable door leaf can be driven up and down by the driving mechanism, so that the half door leaf can be closed and closed. Switch between open and open, so as to adjust the indoor ventilation. In the existing lifting transmission structure, the motor drives the belt or chain to drive a fixed block up and down. The lifting door is directly or indirectly fixed on the fixed block, so that For lifting and lowering, and because the door leaf has great differences in specifications depending on the position of use, the installation position of various transmission components and the size of the belt or chain need to be redesigned, because in the lifting operation, the fixed block must always be maintained In order to achieve the purpose of effectively driving the lifting door, if the running route of the lifting block deviates, it will cause the lifting block to run obliquely, and the door leaf is always vertically lifting, so when the two directions are different, the belt will often be broken Or the chain, so the existing transmission structure lacks flexibility in installation and adjustment
