Problems solved by technology
[0004] The above-mentioned existing technical solutions have the following defects: the above-mentioned multi-stage high-pressure cylinder can greatly increase the expansion and contraction of the cylinder, but in the process of actual use, the air pressure value in each cylinder can only reach a certain level after the cylinder is fully opened. When the air pressure in the cylinder does not reach a stable value, that is, when the maximum elongation is not reached, the air pressure in the cylinder is unstable at this time, that is, it cannot be stretched without reaching full elongation. Keep the cylinder stable at all times. It is dangerous to operate when the required elongation does not reach the longest length. The elongation of the cylinder is difficult to control, so there is still room for improvement.

Embodiment Construction
[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0028] refer to figure 1 , figure 2As shown, it is a telescopic multi-stage high-pressure cylinder ejector device disclosed in the present invention. The telescopic multi-stage high-pressure cylinder ejector device is a lockable structure, that is, it can be extended after a certain length in the actual operation process. Locking makes it difficult for multi-stage cylinders to shrink and elongate, so as to improve the stability and safety of actual operation. The retractable multi-stage high-pressure cylinder pushing device includes an outer cylinder 1. In this embodiment, the outer cylinder 1 is cylindrical, and the outer cylinder 1 is sequentially provided with a first-stage cylinder 2 and a second-stage cylinder from the inner wall to the center of the cylinder. 3 and the third-stage cylinder 4, shaft sealing rings are installed between the outer cylind...

Description
technical field [0001] The invention relates to the technical field of cylinder preparation, in particular to a telescopic multi-stage high-pressure cylinder ejector device. Background technique [0002] As an actuator of industrial control, the cylinder is widely used in material pushing, linear feeding and other occasions, especially in fireproof and explosion-proof occasions, it has incomparable advantages to use cylinder as actuator. In addition to single-stage cylinders, multi-stage cylinders are widely used at present. Multi-stage cylinders are multiple groups of sequential cylinders combined through pneumatic principles to form a smaller volume but greatly increase the elongation. It is widely used in existing lifting and heightening equipment. [0003] For example, the Chinese patent with the notification number CN106837925A discloses a multi-stage high-pressure cylinder, including a shaft seal ring, an outer cylinder, a first-stage cylinder, a second-stage cylinder...
