[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0023] Example 1, reference Figure 1-4 , a self-unloading pressure-adjustable buffer gas booster cylinder, comprising a first cylinder barrel 1 and a second cylinder barrel 2, the first cylinder barrel 1 and the second cylinder barrel 2 are connected by a flange, one end of the first cylinder barrel 1 is provided with a first cylinder sleeve 3, the first cylinder sleeve 3 is provided with an air hole, and an air valve 4 is installed on the air hole, one end of the second cylinder barrel 2 is provided with a second cylinder sleeve 5, the inner wall of the first cylinder barrel 1 is fixed with a fixing plate 9, the middle part of the fixing plate 9 is movably plugged with a first piston rod 13, one end of the first piston rod 13 and the inner wall of the second cylinder sleeve 5 are provided with a matching buffer assembly, the other end of the first piston rod 13 is connected to a second piston rod 8, one end of the second piston rod 8 is connected to a piston 7, the piston 7 is slidably clamped in the interior of the first cylinder barrel 1, and a matching pressure relief structure is provided on the piston 7 and the second piston rod 8, a pressure relief hole 6 is provided on the first cylinder barrel 1, and the diameter of the second piston rod 8 is smaller than the diameter of the first piston rod 13;
[0024] The buffer assembly includes a fixed column 10 fixed to the inner wall of the second cylinder liner 5, one end of the fixed column 10 is connected to a stopper 12, a push plate 19 is slidably sleeved on the fixed column 10, and a first spring 11 is sleeved on the portion of the fixed column 10 located between the push plate 19 and the second cylinder liner 5. The end of the first piston rod 13 facing the stopper 12 is connected to a ferrule 18, and the inner diameter of the ferrule 18 is larger than the diameter of the stopper 12;
[0025] The pressure relief structure includes two T-shaped holes 20 symmetrically opened on the piston 7. A connecting plate 14 is slidably sleeved on the second piston rod 8. Two connecting rods 16 are symmetrically fixed to one side of the connecting plate 14. One end of each connecting rod 16 is connected to a T-shaped sealing block 17. The part of the two connecting rods 16 located between the piston 7 and the connecting plate 14 is sleeved with a second spring 15.
[0026] The two connecting rods 16 pass through the two T-shaped holes 20 respectively. The two T-shaped sealing blocks 17 are sealed and clamped with the two T-shaped holes 20 respectively. Rubber sealing rings are clamped at the inner steps of the two T-shaped holes 20. The two connecting rods 16 have the same length.
[0027] Working principle: pressurized gas enters the first cylinder 1 from the gas valve 4, and the gas pushes the piston 7 to move in the first cylinder sleeve 3, and the piston 7 pushes the second piston rod 8 and the first piston rod 13 to move. When the clamping sleeve 18 at the end of the first piston rod 13 contacts and pushes the push plate 19, and the first spring 11 provides a rebound effect on the push plate 19, the impact of the first piston rod 13 is effectively reduced, and then the impact on the booster cylinder as a whole is reduced, which has a good vibration reduction and noise reduction effect. When the first piston rod 13 and the second piston rod 8 move to the end of the stroke, the connecting plate 14 contacts the fixed plate 9, but when the gas pressure in the first cylinder 1 is too high , the piston 7, the first piston rod 13 and the second piston rod 8 continue to move an end distance. At this time, the piston 7 and the two T-shaped sealing blocks 17 move relative to each other, and the two second springs 15 are compressed. The T-shaped sealing block 17 is disengaged from the two T-shaped holes 20 of the piston 7, and the excess gas passes through the two T-shaped holes 20 and is discharged from the pressure relief hole 6, realizing automatic pressure relief and ensuring the service life of the gas booster cylinder. When the excess gas is discharged, the piston 7 is pushed back under the rebound action of the two second springs 15, so that the T-shaped sealing block 17 is re-engaged with the two T-shaped holes 20 of the piston 7 and forms a seal, ensuring the normal use of the gas booster cylinder.
