Description

Technical Field

[0001] The utility model relates to the technical field of doors, in particular to an anti-collision free door. Background Art

[0002] As the name suggests, anti-collision doors are doors that prevent collisions. They can be opened in both directions through collisions and can be automatically closed by gravity after people or objects pass through. Non-electric doors are called anti-collision free doors. There are many names for anti-collision free doors, such as passage doors, double doors, collision doors, etc. Anti-collision doors (free return doors, anti-collision free doors, impact free doors) have the functions of windproof, dustproof, insect-proof, odor-proof, cold-insulated, heat-insulated, noise-insulated, etc., thereby achieving the effect of improving environmental hygiene.

[0003] In existing technologies, when using anti-collision free doors, the door and door frame are connected by a rebound reset mechanism. Most rebound reset mechanisms use torsion springs or gravity arc rebound structures to assist the door frame in resetting. However, during the door rebound process, the door will rebound to a far position in the opposite direction, usually requiring multiple rebounds to complete the door closing. This repeated rebound process causes certain inconvenience to those who need to open the door later. If carts are continuously used to transport materials, subsequent carts may miss the rhythm of the door's reciprocating motion, resulting in certain impact forces, causing inconvenience during transportation. It is also not impact-resistant, increases mechanical wear, shortens service life, increases maintenance costs, and is inconvenient to use. In view of this, we have introduced the anti-collision free door. Utility Model Content
