Lifting door convenient to mount

Abstract

The invention discloses a lifting door convenient to mount. The lifting door comprises a base lifting frame, an upper end limiting plate, a supporting mechanism, a folding door and a connecting plate.The lower end of the base lifting frame and an external connection lifting device are connected and fixed, the upper end of the base lifting frame and the connecting plate are connected through a hinge and are fixed together, the connecting plate is divided into an upper plate and a lower plate, the upper portion of the connecting plate on the upper end is connected to the end face of the upper end limiting plate through a hinge, the folding door is connected to the lower portion of the connecting plate on the upper end, the upper portion of the connecting plate on the lower end is connectedwith the folding door, and the lower portion of the connecting plate on the lower end is connected with the base lifting frame. The lifting door is simple and reasonable in design, easy and convenientto operate and convenient to mount. The lifting door can be conveniently mounted in walls on the two sides of the lifting door through supporting steel frames on the two ends, through rubber plates and rubber grooves of two adjacent folding doors, the sound insulation effect of the folding door can be improved, and the rubber plates can prevent fingers from being hurt due to pinch in the foldingprocess.

Description

technical field [0001] The invention relates to the technical field of lift gate equipment, in particular to a lift gate that is easy to install. Background technique [0002] The lifting door is a kind of industrial door that is lifted vertically or turning along the wall with the help of a spring balance device and a small power transmission system. [0003] The lifting door in the prior art is mainly composed of a push-pull member and a slide member. When in use, the pulley block of the push-pull member slides back and forth on the slide rail of the slide member to push and pull to open or close. The lifting of this type of structure After the door is used for a period of time, it will deform, so that there will be gaps between the door leaf and the door leaf and between the door leaf and the door frame, which will cause rainwater and dust to enter the room from the gap, which will affect people's life and property. To a great extent, the effect of heat insulation and so...

AI Technical Summary

Problems solved by technology

[0007] However, during the operation of these existing lifting doors, the cylindrical nails in the clamping holes will be rotated by lifting or falling, which will cause loosening, which has a great potential safety hazard, and the sliding blocks in the guide rails will be damaged after a long period of use. stuck, inconvenient to replace
