This utility model relates to the field of water rocket landing chamber technology and discloses a water rocket parachute chamber, including a water rocket body. A disc is provided on the top of the water rocket body, and a through mounting hole is opened on the disc. The disc is fitted onto the top of the water rocket body through the mounting hole. A through threading hole is opened on the disc. A ring is fixedly connected to the disc. Solid cylinders A and B are symmetrically fixedly connected to the outer circumference of the disc ring. Through the design of the blocking column, the tilting driving force can be strengthened and the separation efficiency can be improved. That is, when the elastic band A is released and a rapid rebound occurs, the rebound force acts on the blocking column to generate an impact force. This impact force directly exacerbates the tilting of the parachute chamber towards the solid cylinder A. The above-mentioned actively enhanced tilting trend allows the parachute chamber cover to detach from the main body more quickly and thoroughly, avoiding separation jamming caused by insufficient tilting force, and greatly improving the overall separation efficiency of the cover.

This utility model relates to a delayed-release air-separation lower-stage rocket assembly connector for water rockets, used to connect two rocket bodies to form a single lower-stage rocket body. The assembly connector has a hollow screw body and a one-way valve body that is hollowly connected to the interior of the hollow screw body. The assembly connector also has a micro-hole communicating with an internal airflow channel of the hollow screw body. When the lower-stage rocket body is assembled, the micro-hole and the one-way valve body are located within the same rocket body, and the hollow screw body extends into the other rocket body. During water rocket launch, after the lower rocket body loses pressure, the air pressure in the upper rocket body can only be slowly released to the lower rocket body through the micro-hole. This significantly prolongs the depressurization time in the upper rocket body, thereby extending the time for triggering the air-separator assembly to achieve release and separation. This extends the separation time between the upper and lower rocket bodies, allowing for an interval of 1-2 seconds between launch and separation, which is more than 10 times longer than existing technologies.

This utility model discloses a multifunctional base for making water rockets, relating to the field of water rocket manufacturing technology. It includes a cola bottle and a cylindrical base. The cylindrical base is snapped into the cola bottle. A threaded through hole is formed at the center of the bottom of the cylindrical base. Four sets of strip-shaped grooves are evenly spaced on the cylindrical base. The top of the cylindrical base abuts against a semi-circular card. Two sets of semi-circular cards are provided, with their inner walls abutting against the outer wall of the cola bottle. A trapezoidal placement block is provided on the outer wall of the cylindrical base. The threaded through hole is threadedly connected to a threaded collar, which is connected to a bottom blocking plate. The bottom blocking plate abuts against the cylindrical base. Through the snapping of the cylindrical base with the cola bottle and the abutting action of the semi-circular cards, the cola bottle is stably fixed, effectively preventing the bottle from shaking during drilling and ensuring that the drilled hole is centered on the cola bottle. The strip-shaped grooves on the cylindrical base reduce the weight of the base while limiting the position of the tail fin attachment, ensuring the symmetry of the tail fin attachment.
