Description

Technical Field

[0001] This invention relates to parachute sealing, and more specifically to a pressure sealing device and method for a square parachute pack. Background Technology

[0002] During routine maintenance, parachutes need to be periodically removed from their cases, inspected, aired, and repackaged. The packaging requires a certain sealing pressure to facilitate insertion into the case and deployment after removing the sealing pin. Depending on the required packaging density, this cannot be accomplished manually without the assistance of 2-3 people with considerable strength. For parachutes with specific shape requirements, it is difficult to achieve the correct shape by hand, making the entire packaging process time-consuming and labor-intensive.

[0003] Currently, hydraulic umbrella wrapping machines can provide high pressure, but after the umbrella is removed from the machine, the canopy will expand and the umbrella will deform. In addition, hydraulic umbrella wrapping machines are bulky and inconvenient to transport and move. They can only be used for indoor umbrella wrapping and cannot be adapted to various working environments such as outdoors. Summary of the Invention

[0006] Furthermore, the rectangular frame (2) and the base (4) are integrated; or, the rectangular frame (2) is positioned and inserted on the upper side of the base (4).

[0007] Preferably, the rectangular frame (2) has openings on its four sides for weight reduction.

[0008] Preferably, during operation, one end of the tightening band (5) is looped around the fixed sleeve shaft (63) of the tensioner (6) via the rope loop (51), and the other end of the tightening band (5) passes through the outer side of one side of the rectangular frame (2), the opening slot (42), the outer side of the other side of the rectangular frame (2), the pressure block (1), and then passes through the tensioning sleeve shaft (61) of the tensioner (6). Adjusting the tensioning handle (62) of the tensioner (6) can tighten the tightening band (5).
