Detailed Description
As shown in fig. 1 and fig. 2, the present invention provides an adjustable airflow spring rod device, which mainly comprises a movable rod 1, a barrel 2, a spring 3, an elastic force control ring 4, an airflow chamber 5, a locking ring 6 and a locking ring 7, wherein the airflow chamber 5 is provided with a main valve switch 501, an air inlet check valve 502 and an air outlet check valve 503; the head of the movable rod 1 is provided with a sealing ring 101 and is connected with the cylinder body 2 to perform piston motion; a spring 3 is arranged in the cylinder body 2 and is connected with an elastic force control ring 4 through a rotary thread, and a sealing ring 402 is arranged at the joint of the elastic force control ring 4; the elastic force control ring 4 is connected with the airflow chamber 5 in a spiral way, and a sealing ring 504 is arranged at the joint of the airflow chamber 5; the locking ring 6 is used for locking the elastic force control ring 4 reversely, and the locking ring 7 is used for locking the airflow chamber 5 reversely.
As can be seen in fig. 3, adjustment of the spring force control ring 4 can change the stroke of the spring 2; and when needed, the length of the spring rod device shortened due to the elastic force adjustment can be adjusted and compensated by the rotating airflow chamber 5.
As shown in fig. 4, the center of the spring contact surface 401 of the elastic force control ring 4 is hollow, so that the air flow can pass through smoothly; an inlet of the airflow chamber 5 is provided with an airflow main valve switch 501, and when the airflow main valve switch is closed, the airflow cannot enter and exit, so that the movement of the movable rod 1 can be stopped at any time (see fig. 5); an adjustable air inlet check valve 502 and an adjustable air outlet check valve 503 are arranged behind a main valve switch 501, when the main valve switch 501 is opened, the larger the air inlet of the air inlet check valve 502 is adjusted, the faster the rebound speed of the device is, and vice versa; the larger the outlet adjustment of the outlet check valve 503, the faster the compression speed of the device, and vice versa.
