Description

Technical Field

[0001] The present invention belongs to the technical field of parachutes, and more specifically, relates to a packaging structure and a packaging method for a parachute. Background Art

[0002] Currently, whether in the fields of aviation and aerospace or the airdrop and airborne of equipment systems, all parachutes are directly packaged, transported, stored, and applied under normal atmospheric pressure in the atmosphere.

[0003] The existing packaging of parachutes is mainly manual operation, specifically consisting of three people. Two of them continuously reduce the size of the sealing opening until the requirements are met and hold it, while the third person quickly seals and ties the knot, thereby achieving the manual packaging of the parachute.

[0004] However, in the above process, the requirements for personnel are relatively high. Especially for parachutes with larger sizes, it is difficult to control manually, resulting in a complex packaging process, a long cycle, and poor packaging density. Summary of the Invention

[0005] In view of the above defects or improvement requirements of the prior art, the present invention provides a packaging structure and a packaging method for a parachute, aiming to not only conveniently achieve the vacuum packaging of the parachute, improve the packaging density, but also quickly realize the use of the parachute.

[0006] In a first aspect, the present invention provides a packaging structure for a parachute, and the packaging structure includes a packaging film and a connection component;

[0007] The packaging film is of an annular structure, and both ends of the packaging film respectively have annular connection films. Each annular connection film includes two connection films that can be heat-sealed and sealed, so as to seal the parachute in a sealed cavity formed by the packaging film and the two annular connection films. The middle of the connection film of one annular connection film has an air extraction port, and the air extraction port communicates with the sealed cavity;

[0008] The connection component includes a first connection loop for connecting the opening cable loop of the parachute and a second connection loop for connecting the suspension line loop of the parachute. The first connection loop passes through the two connection films of one annular connection film, and the second connection loop passes through the two connection films of the other annular connection film.

[0009] Optionally, each connection film has a through hole, and the outer edges of two opposite through holes are hermetically connected together. The first connection loop passes through the two through holes of one annular connection film, and the second connection loop passes through the two through holes of the other annular connection film.

[0010] Optionally, reinforcing sheets are arranged on the outer surfaces of the two connecting membranes of one of the annular connecting membranes, the reinforcing sheets cover the outer edges of the through holes, and the first connecting cable loop passes through the reinforcing sheets.

[0011] Optionally, an air stop valve sheet is movably inserted into the air extraction port to seal the air extraction port.

[0012] Optionally, both the first connecting cable loop and the second connecting cable loop include a first ring body and a second ring body, and one end of the first ring body is hinged to one end of the second ring body so that the other end of the first ring body is movably abutted against the other end of the second ring body.

[0013] Optionally, the packaging film is an elastic structural member.

[0014] In a second aspect, an embodiment of the present invention provides a packaging method for a parachute. The packaging method is based on the packaging structure described in the first aspect, and the packaging method includes:

[0015] Place the parachute in the packaging film so that the opening cable loop is arranged between the two connecting membranes of one of the annular connecting membranes, and the cable bundle loop is arranged between the two connecting membranes of the other annular connecting membrane;

[0016] Heat-seal the outer edges of the two connecting membranes of each annular connecting membrane together, and suck the air extraction port;

[0017] The first connecting cable loop passes through the two connecting membranes of one of the annular connecting membranes, and the second connecting cable loop passes through the two connecting membranes of the other annular connecting membrane.

[0018] Optionally, the first connecting cable loop passes through the two connecting membranes of one of the annular connecting membranes, and the second connecting cable loop passes through the two connecting membranes of the other annular connecting membrane, including

[0019] Heat-seal the two connecting membranes corresponding to the inner hole of the opening cable loop together and open a through hole, and heat-seal the two connecting membranes corresponding to the inner hole of the cable bundle loop together and open a through hole;

[0020] Pass the first connecting cable loop and the second connecting cable loop through the corresponding through holes respectively.

[0021] The beneficial effects brought by the technical solution provided by the embodiment of the present invention are:

[0022] For a packaging structure for a parachute provided by an embodiment of the present invention, when packaging the parachute, first, place the parachute in the packaging film through the intervals between the connecting films, so that the opening cord loop is arranged between two connecting films of an annular connecting film, and the cord bundle loop is arranged between two connecting films of an annular connecting film, thereby realizing the preliminary packaging of the parachute. Then, heat-seal the outer edges of the two connecting films of each annular connecting film together, and aspirate the air extraction port, so as to form a negative pressure value by extracting the air in the sealed cavity and reaching a predetermined vacuum degree, and utilize the atmospheric pressure outside the sealed cavity to evenly compact the parachute in the bag in all directions. In this way, it can quickly and conveniently change its relatively low loose packing density in the normal pressure environment to a relatively high compacted density under vacuum conditions, and improve the packing density.

[0023] Finally, pass the first connecting cord loop through the two connecting films of an annular connecting film, and pass the second connecting cord loop through the two connecting films of another annular connecting film. In this way, the arrangement of the first connecting cord loop and the second connecting cord loop can be realized, so as to conveniently realize the quick connection of the opening cord loop and the cord bundle loop, and facilitate the quick connection to the parachute opener and the load in the subsequent implementation, so as to improve the efficiency when used subsequently.

[0024] During the actual use process, the first connecting cord loop can be directly connected to the parachute opener, and the second connecting cord loop can be directly connected to the load of the aircraft type. When it is necessary to drop the aircraft (at this time, the entire packaging structure and the parachute are arranged on the aircraft), by launching the parachute opener upward, and under the downward gravity of the aircraft itself, the packaging film is quickly torn (the packaging film is subjected to upward and downward forces), the packaging film opens, the parachute opener detaches, and the parachute automatically unfolds under the wind, thereby realizing the landing of the aircraft.

[0025] That is to say, a packaging structure for a parachute provided by an embodiment of the present invention can not only conveniently realize the vacuum packaging of the parachute, improve the packing density, but also quickly realize the use of the parachute. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] Figure 1 is a partial perspective view of a packaging structure for a parachute provided by an embodiment of the present invention, as Figure 1 shown, the packaging structure includes a packaging film 1 and a connecting component 2.

[0032] The packaging film 1 is of an annular structure. Both ends of the packaging film 1 are respectively provided with annular connecting films 11. Each annular connecting film 11 includes two connecting films 111 that can be heat-sealed to seal the parachute 100 in the sealing cavity 12 formed by the packaging film 1 and the two annular connecting films 11. The middle of the connecting film 111 of one annular connecting film 11 has an air extraction port 1111, and the air extraction port 1111 communicates with the sealing cavity 12.

[0033] The connecting component 2 includes a first connecting cable loop 21 for connecting the parachute opening cable loop 110 of the parachute 100 and a second connecting cable loop 22 for connecting the parachute cord bundle loop 120 of the parachute 100. The first connecting cable loop 21 passes through the two connecting films 111 of one annular connecting film 11, and the second connecting cable loop 22 passes through the two connecting films 111 of the other annular connecting film 11.

[0034] For a packaging structure for parachutes provided by an embodiment of the present invention, when packaging a parachute 100, first, the parachute 100 is placed in the packaging film 1 through the interval between the connecting films 111, so that the parachute opening ring 110 is arranged between the two connecting films 111 of an annular connecting film 11, and the parachute rope ring 120 is arranged between the two connecting films 111 of an annular connecting film 11, thereby realizing the preliminary packaging of the parachute 100. Then, the outer edges of the two connecting films 111 of each annular connecting film 11 are heat-sealed together, and the air extraction port 1111 is sucked, so that the air in the sealed cavity 12 is extracted and reaches a predetermined vacuum degree to form a negative pressure value, and the atmospheric pressure outside the sealed cavity 12 is used to uniformly compact the parachute 100 in all directions in the bag, so that the smaller loose density in a normal pressure environment can be quickly and conveniently converted into a larger compacted density under vacuum conditions, thereby improving the packaging density.

[0035] Finally, the first connecting ring 21 is passed through the two connecting membranes 111 of an annular connecting membrane 11, and the second connecting ring 22 is passed through the two connecting membranes 111 of another annular connecting membrane 11. In this way, the arrangement of the first connecting ring 21 and the second connecting ring 22 can be realized, so as to facilitate the quick connection of the parachute opening ring and the parachute rope ring 120, and facilitate the quick connection to the parachute opener and the load in the subsequent implementation, so as to improve efficiency in subsequent use.

[0036] In actual use, the first connecting grommet 21 can be directly connected to the parachute opener, and the second connecting grommet 22 can be directly connected to the aircraft-like load (to avoid premature disassembly of the packaging film 1). When it is necessary to drop the aircraft (at this time, the entire packaging structure and the parachute 100 are arranged on the aircraft), the parachute opener is launched upward, and the packaging film 1 is quickly torn under the aircraft's own gravity (the packaging film 1 is subjected to upward and downward forces), the packaging film 1 is opened, the parachute opener is detached, and the parachute 100 is automatically deployed by the wind, thereby achieving the landing of the aircraft.

[0037] That is to say, the packaging structure for a parachute provided by the embodiment of the present invention can not only conveniently realize the vacuum packaging of the parachute 100 and improve the packaging density, but also quickly realize the use of the parachute.

[0038] The vacuum degree of the packaging structure provided by the present invention can be controlled at 600-1333 Pa, and the packaging compaction density reaches above 0.7 kg / L.

[0039] It should be noted that the two sides of the two connection films 111 are connected in sequence to form the annular connection film 11 .

[0040] The parachute 100 includes a main parachute, suspension lines, and a suspension line bundle ring 120 that are connected in sequence. Among them, the suspension line bundle ring 120 plays a role in connecting the load through the second connecting cable loop 22. A connecting rope with relatively low strength is connected between the opening cable loop 110 and the main parachute. When the opener pulls the opening cable loop 110 upward, the connecting rope will be broken after the packaging film 1 is torn, thus finally realizing the separation of the opener and the parachute.

[0041] Continue to refer to Figure 1 , each connecting film 111 has a through hole 1112, and the outer edges of two opposite through holes 1112 are hermetically connected together. The first connecting cable loop 21 passes through the two through holes 1112 of an annular connecting film 11, and the second connecting cable loop 22 passes through the two through holes 1112 of another annular connecting film 11.

[0042] In the above embodiment, the through holes 1112 facilitate the arrangement of the first connecting cable loop 21 and the second connecting cable loop 22. In addition, the hermetic sealing of the outer edge of the through hole 1112 can prevent the sealing cavity 12 from communicating with the outside.

[0043] In this embodiment, reinforcing pieces 1113 are arranged on the outer surfaces of the two connecting films 111 of an annular connecting film 11. The reinforcing pieces 1113 cover the outer edge of the through hole 1112, and the first connecting cable loop 21 passes through the reinforcing pieces 1113.

[0044] In the above embodiment, the reinforcing pieces 1113 can increase the strength of the top connecting film 111, ensure the structural strength around the through hole 1112, and avoid the problem that the packaging film 1 cannot be torn open due to this part being torn open during subsequent use.

[0045] Exemplarily, a gas stop valve piece is movably inserted on the air extraction port 1111 to seal the air extraction port 1111, thereby preventing external gas from entering the sealing cavity 12 after the suction is completed and reducing the packaging density.

[0046] For the first connecting cable loop 21 and the second connecting cable loop 22, both the first connecting cable loop 21 and the second connecting cable loop 22 include a first ring body and a second ring body. The other end of the first ring body is movably hinged to one end of the second ring body to abut one end of the first ring body against the other end of the second ring body.

[0047] In the above embodiment, by hinging one end of the first ring body and one end of the second ring body, the opening and closing of the first connecting cable loop 21 and the second connecting cable loop 22 can be conveniently realized, so as to quickly realize the connection of the first connecting cable loop 21 to the opening cable loop 110 and the opener, and the connection of the second connecting cable loop 22 to the suspension line bundle ring 120 and the load.

[0048] Exemplarily, the packaging film 1 is an elastic structural member to avoid bumping and abrasion. For example, materials such as polyester, nylon, plastic, or silica gel are used. In addition, the packaging film 1 also has advantages such as low air permeability, good airtightness, strong oxygen barrier property, excellent vacuum pumping effect, moisture-proof performance, good anti-static function, easy heat sealing, not easy to age, and convenient storage. Moreover, when placed statically or under low-intensity vibration, its tensile strength and puncture resistance are relatively good. Therefore, the packaging structure can significantly reduce potential damages such as material oxidation, moisture, prevention of microbial mildew and corrosion, and insect and rodent bites of the parachute in natural air.

[0049] Figure 2 is a flowchart of a packaging method for a parachute provided by an embodiment of the present invention. As Figure 2 shown, this packaging method is based on the above packaging structure, and this packaging method includes:

[0050] S201. Place the parachute 100 inside the packaging film 1 such that the ripcord loop 110 is arranged between the two connecting films 111 of a circular connecting film 11, and the shroud line loop 120 is arranged between the two connecting films 111 of another circular connecting film 11.

[0051] S202. Heat-seal the outer edges of the two connecting films 111 of each circular connecting film 11 together, and suck on the air extraction port 1111.

[0052] S203. The first connecting loop 21 passes through the two connecting films 111 of a circular connecting film 11, and the second connecting loop 22 passes through the two connecting films 111 of another circular connecting film 11.

[0053] During actual use, the first connecting loop 21 can be directly connected to the ripcord, and the second connecting loop 22 can be directly connected to the load of an aircraft (to avoid prematurely disassembling the packaging film 1). When it is necessary to drop the aircraft (at this time, the entire packaging structure and the parachute 100 are arranged on the aircraft), by launching the ripcord upward, and under the downward gravity of the aircraft, the packaging film 1 is quickly torn (the packaging film 1 is subjected to upward and downward forces), the packaging film 1 opens, the ripcord detaches, and the parachute 100 automatically unfolds, thereby realizing the landing of the aircraft.

[0054] That is to say, a packaging method for a parachute provided by an embodiment of the present invention can not only conveniently achieve the vacuum packaging of the parachute 100, improve the packaging density, but also quickly realize the use of the parachute.

[0055] Step S203 includes:

[0056] (1) Heat-seal the two connecting membranes 111 corresponding to the inner hole of the parachute-opening cable loop 110 together and open the through-hole 1112. Heat-seal the two connecting membranes 111 corresponding to the inner hole of the parachute-rope bundle loop 120 together and open the through-hole 1112.

[0057] (2) Pass the first connecting cable loop 21 and the second connecting cable loop 22 through the corresponding through-holes 1112 respectively.

[0058] In the above embodiment, by heat-sealing the two connecting membranes 111 corresponding to the inner hole of the parachute-opening cable loop 110 or the parachute-rope bundle loop 120 together, the two connecting membranes 111 here are heat-sealed together to form a "single-layer membrane". This not only facilitates the opening of the through-hole 1112, but also ensures the sealing around the through-hole 1112, avoiding the communication between the through-hole 1112 and the sealing cavity 12. Moreover, the first connecting cable loop 21 and the second connecting cable loop 22 can just pass through the parachute-opening cable loop 110 and the parachute-rope bundle loop 120 respectively to achieve the connection.

[0059] Those skilled in the art can easily understand that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
