Blind coil spring structure and blind

A blind coil spring structure, comprising:

• a coil spring housing, provided with a storage cavity, wherein the storage cavity is internally provided with a plurality of coil springs;
• a connection assembly, configured to connect the plurality of coil springs in parallel;
• a lubrication assembly, disposed in the coil spring housing, and comprising a storage mechanism, a triggering mechanism, and a liquid outlet mechanism, wherein the storage mechanism is configured to store lubricating grease;
• the triggering mechanism is configured to trigger and activate the liquid outlet mechanism when the coil spring is stretched;
• and the liquid outlet mechanism is configured to release the lubricating grease from the storage mechanism to the coil spring;
• and
• a vibration damping assembly, disposed in the storage cavity, and comprising a contact mechanism and a damping mechanism, wherein the contact mechanism is configured to make the damping mechanism contact the coil spring;
• and the damping mechanism is configured to reduce a vibration generated during movement of the coil spring.
