Description

Technical Field

[0001] The utility model belongs to the field of rocket training bombs, in particular to a rocket training bomb parachute bag. Background Art

[0002] Rockets are propulsion devices that use solid chemical propellants as a power source and are widely used in defense, military industry, aerospace and other fields. The combustion chamber is the place where propellants are stored and burned in the structure of a solid rocket engine. The volume of its inner cavity directly determines the amount of propellant charge, which in turn affects the launch performance of the solid rocket engine. Current rocket training bombs usually use automatic parachute opening devices. Traditional automatic parachute opening devices rely on wind force and resistance to open the deceleration parachute. Once a problem occurs, it is difficult to respond in time and is prone to occur. In the production of rocket training bombs, before the parachute is assembled with the rocket shell, the parachute often has multiple parachute bodies tangled due to its ropes. Before the subsequent parachute installation, it takes a long time to separate the knotted and entangled parachutes, which undoubtedly brings inconvenience to production and adds tediousness. Utility Model Content

[0003] The utility model aims to provide a rocket training parachute bag, which has the advantages of being easy to store parachutes, reducing the inconvenience and tediousness of sorting out and separating knotted and chaotic parachutes before assembly, and at the same time being easy to use later and reducing the need to fix ropes by hands.

[0005] The above technical solution is adopted: when storing the parachute of the rocket training bomb, the pull-trap 1 and the pull-trap 2 are preferably separated by the zipper head, so as to separate the bag tube 1 from the bag cover. Then the operator takes the end of the rope body, passes the rope body from the end of the bag tube 1 through the bag tube 1 and the ring, and then tightens the rope so that most of one end of the rope is exposed outside the end of the ring, and the other end of the rope is located at the other end inside the bag tube 1. At this time, the parachute body part will be located inside the bag tube 1, but there is still a part outside the bag tube 1. The operator arranges the parachute body part outside the bag tube 1 and stuffs it into the bag tube 1, and then uses the zipper head to cooperate with the pull-trap 1 and the pull-trap 2 to bite and close it, so as to realize the covering use of the bag cover and the bag tube 1. Then the operator clamps the rope upward inside the clamping groove, and then gradually wraps the rope around the surface of the ring. At this time, the rubber ring increases the friction force of the surface of the ring. The arrangement of the clamping piece and the clamping groove can help limit the position of the rope being wound, making it easier to wind the rope later and reducing the need to fix the rope with the hands. After the rope is wound, the second wrapping tube can be taken out and the outer ring and the inner ring can be connected by threads to achieve the connection and fixation between the first wrapping tube and the second wrapping tube. The storage and use of the parachute can be completed through this arrangement. Before assembling the parachute with the rocket training bomb, the storage and arrangement of the parachute can be achieved, reducing the inconvenience and tediousness of sorting and separating the knotted and chaotic parachute before assembly.

[0006] The utility model is further configured such that the first pull tab and the second pull tab are mutually engaged and snap-fitted, and the surfaces of the first pull tab and the second pull plate are mutually engaged with zipper heads.

[0007] The above technical solution is adopted: the zipper head cooperates with the first pull tab and the second pull tab to engage and close the zipper.

[0008] The utility model is further configured that an end ring located inside the second pull tab is fixedly mounted on one end of the first bag tube.

[0009] The above technical solution is adopted: the end ring is used in conjunction with the wrapping tube.

[0010] The utility model is further configured that an internal thread is provided inside the outer ring, an external thread is provided on the surface of the inner ring, and the internal thread and the external thread are threadedly connected to each other.

[0011] The above technical solution is adopted: the inner bolt is connected with the outer thread by thread, and the outer ring and the inner ring are fastened and installed.

[0012] The utility model is further configured that the surface of the outer ring is provided with an anti-slip groove, and the surface of the surrounding ring is fixedly sleeved with a rubber ring.

[0013] The above technical solution is adopted: the friction force of the outer ring surface is increased by the anti-slip groove, and the friction force of the surrounding ring surface is increased by the rubber ring.

[0014] The utility model is further configured that a fixing rod is fixedly installed inside the clamping member, and the fixing rod and the winding ring are fixedly installed with each other.

[0015] The above technical solution is adopted: the clamping part is supported and fixed by a fixing rod.

[0016] The utility model is further configured that a handle is fixedly mounted on one side of the bag cover, and a non-slip sleeve is fixedly sleeved on the surface of the handle.

[0017] By adopting the above technical solution, the umbrella bag can be easily taken out through the handle, and the anti-slip cover increases the friction force on the surface of the handle.

[0018] The utility model is further configured that an insert ring is fixedly installed at one end of the outer ring, and a slot for plugging in with the insert ring is opened at the other end of the sleeve.

[0019] The above technical solution is adopted: by plugging the plug ring into the slot, it is convenient to coordinate the outer ring and the package tube for positioning and use.
