AI Technical Summary
Existing floor springs cannot achieve one-way opening, making it difficult to meet the needs of special locations where doors can only open to one side.
By setting up a combination structure of adjusting wheel, eccentric wheel, rotating plate and blocking key, the rotation of the floor spring can be controlled in one direction or two directions. The opening in one direction or two directions can be achieved by the engagement of the eccentric wheel and the ball stop and the elastic force of the thrust spring.
It enables one-way or two-way rotation control of the floor spring, meeting the needs of special places for one-way door opening, while maintaining the two-way function of ordinary floor springs.
