A detachable spacer structure suitable for fast doors

Abstract

The invention relates to the field of mechanical devices, in particular to a detachable cushion block structure applicable to a fast door. The detachable cushion block structure comprises a door board, an electric control box for transmitting control signals and a driving device used for receiving signals of the electric control box to drive the door board to move up and down. The detachable cushion block structure is characterized in that a cushion block made of an elastic material is connected at one end of the door board close to the ground, and the cushion block and the door board are detachably connected through a connecting piece. The cushion block comprises lateral cushion entity areas located on two sides, a center cushion column area located at the center of each lateral cushion entity area and a dust-roof curtain connected in the front-back direction at the lower end of the door board and wrapping the lateral cushion entity area and the center cushion column area. The detachable cushion block structure is convenient to detach and replace, and good supporting force and elastic protection are achieved by means of design of the cushion block.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a detachable pad structure suitable for fast doors. Background technique [0002] Fast door, also known as fast rolling door, high-speed door or high-speed rolling door, refers to a door with a running speed of more than 0.6 meters per second. Specifically, it refers to a fast-moving barrier-free isolation door. Dust-proof, insect-proof, sound insulation, etc.; fast doors can keep the workshop in a constant temperature, constant humidity, and clean working environment, and can be widely used in food, medicine, electronics, rubber, chemicals, automobiles, textiles, logistics and other fields. [0003] When the fast door is raised and lowered quickly, in order to avoid the damage of the components caused by the excessive contact speed with the ground, and also to avoid the sudden appearance of obstacles or pedestrians, avoiding injuries caused by the delay, the manufacturer will...

Problems solved by technology

[0003] When the fast door is raised and lowered quickly, in order to avoid the damage of the components caused by the excessive contact speed with the ground, and also to avoid the sudden appearance of obstacles or pedestrians, avoiding injuries caused by the delay, the manufacturer will add a It is protected by pads made of elastic materials. Since the high-speed door is closed and opened many times a day, frequent impacts make the pads wear quickly
