Description

Technical Field

[0001] This invention relates to the field of military camouflage technology, and in particular to a vertical missile launch tube decoy that can be quickly folded and unfolded. Background Technology

[0002] On the battlefield, decoys are set up to deceive and confuse the enemy, protecting genuine targets from destruction and concealing operational intentions. Vertical launch vehicles (VLVVs) are the carriers for loading and launching missiles, serving as important targets for enemy attacks and also as crucial decoys. Currently, VLV decoys primarily employ two types: inflatable and modular.

[0003] Inflatable vertical launch vehicles are large, have long inflation and retrieval times, and are weak in wind resistance. Most of them only have a visible light appearance and lack infrared and radar characteristics. In particular, after deployment, decoys are difficult to move, and the vertical and horizontal states of the launch tubes are difficult to switch, making them easy to detect and identify in the face of enemy information-based multi-source fusion reconnaissance and surveillance.

[0004] The assembled vertical launch vehicle decoy uses an "existing support vehicle plus a self-made missile launch tube" design. Because it uses a support vehicle as the carrier and transport platform, possesses infrared and radar characteristics, and is mobile, it achieves a high degree of realism and is currently widely used. However, the self-made missile launch tube suffers from problems such as low realism in its shape, difficulty in overall assembly and disassembly, low strength, poor stability, and poor durability, making it unsuitable for long-term use and inconvenient to assemble and disassemble.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Example 1

[0042] This invention provides a vertical missile launch tube decoy that can be quickly folded and unfolded, such as... Figure 1 As shown, the missile launch tube decoy includes:

[0043] Multiple bases 1, each base 1 including a hand-cranked winch.

[0044] Furthermore, the base 1 also includes: a connecting column 11, each end of which is provided with a threaded hole; a bottom support buckle 12 and a bottom support ear 13, both of which are engaged with the threaded holes at the ends of the connecting column 11 by bolts, so that the bottom support buckle 12 and the bottom support ear 13 are fixedly disposed at both ends of the connecting column 11; a hand-cranked winch support frame 15, which is fixedly disposed at the middle position of the connecting column 11, and is installed in conjunction with the hand-cranked winch; and a support base 14, which is disposed below the bottom support ear 13, and has a cylinder on it; wherein the holes on the bottom support buckle 12 and the bottom support ear 13 and the cylinder form a first channel.

[0045] Specifically, base 1 is the bottom support structure of the missile launch tube decoy. The number of bases 1 can be set according to actual needs, and there is no specific limitation in this embodiment. In this embodiment, two bases 1 are preferred. Furthermore, as... Figure 4 As shown, each base 1 includes a connecting post 11, a bottom support lug 12, a bottom support lug 13, a support base 14, and a hand-cranked winch support frame 15. Specifically, threaded holes are provided at both ends of the connecting post 11. These threaded holes, in conjunction with the bottom support lug 13 and the bottom support lug 12, allow the connecting post 11 to be connected to the bottom support lug 13 and the bottom support lug 12. The bottom support lug 12 and the bottom support lug 13 are connected to the threaded holes on the connecting post 11 by bolts, thus enabling the bottom support lug 12 and the bottom support lug 13 to be connected. 13 can be vertically fixed on both sides of the connecting column 11; the hand-cranked winch support frame 15 is fixedly installed at the middle position of the connecting column 11 by bolts, so that a hand-cranked winch of the corresponding size that matches its hole can be installed on the hand-cranked winch support frame 15; the support base 14 is installed at both ends of the connecting column 11 and is located below the bottom support lug 13. The support base 14 has a cylinder, so that the hole on the bottom support lug 12, the bottom support lug 13 and the cylinder can form a channel, so that other components can be accommodated in the first channel.

[0046] The foldable bracket 2 includes: a frame, which is nested on the base 1 and is perpendicular to the base 1; and a support block 29, which is disposed at the top of the frame and has a first through hole.

[0047] Furthermore, the frame includes: a plurality of first connecting pipes 21, a plurality of second connecting pipes 22, a plurality of third connecting pipes 23, a plurality of fourth connecting pipes 24, and a plurality of fifth connecting pipes 27, wherein the plurality of first connecting pipes 21, the plurality of second connecting pipes 22, the plurality of third connecting pipes 23, the plurality of fourth connecting pipes 24, and the plurality of fifth connecting pipes 27 form a frame with an isosceles trapezoidal cross-section; after the first connecting pipe 21 passes through the first channel, the bottom support lug 12 is tightened by bolts so that the bottom support lug 12 and the bottom support lug 13 cooperate to connect the first connecting pipe. 21 clamps the cylinder, wherein the first connecting pipe 21 and the cylinder are positioned by a spring pin; the second connecting pipe 22 is located at the short side of the isosceles trapezoidal frame and is distributed between two of the first connecting pipes 21; the third connecting pipe 23 is located at the long side of the isosceles trapezoidal frame and is distributed between the other two first connecting pipes 21; the fourth connecting pipe 24 is distributed between the second connecting pipe 22 and the third connecting pipe 23; and the fifth connecting pipe 27 is located at the hypotenuse of the isosceles trapezoidal frame and is located at the top of the first connecting pipe 21.

[0048] Furthermore, the foldable bracket 2 also includes: a connector, which includes a three-way connector 26, a straight connector 25, and a spring pin. Mounting holes are provided at the connection points of the first connecting pipe 21, the second connecting pipe 22, the third connecting pipe 23, the fourth connecting pipe 24, and the fifth connecting pipe 27. The first connecting pipe 21, the second connecting pipe 22, the third connecting pipe 23, the fourth connecting pipe 24, and the fifth connecting pipe 27 are connected and positioned by the three-way connector 26, the straight connector 25, the spring pin, and the mounting holes. A second pulley group 28 is mounted on the support block 29 and is used to limit, support, and reduce friction on the splicing column 31.

[0049] Specifically, the foldable bracket 2 is a frame structure, that is, the foldable bracket 2 includes a frame, and then the frame is nested on the base 1, so that the foldable bracket 2 and the base 1 can be set perpendicularly.

[0050] Furthermore, such as Figure 5As shown, the frame includes multiple first connecting pipes 21, multiple second connecting pipes 22, multiple third connecting pipes 23, multiple fourth connecting pipes 24, and multiple fifth connecting pipes 27. These multiple first connecting pipes 21, multiple second connecting pipes 22, multiple third connecting pipes 23, multiple fourth connecting pipes 24, and multiple fifth connecting pipes 27 form a spatial structure, making the cross-section of the frame an isosceles trapezoid.Specifically: the first connecting tube 21 is a vertical tube, and the number of the first connecting tubes 21 can be set according to actual needs. This embodiment does not impose a specific limitation, but in this embodiment, four first connecting tubes 21 are preferred. These four first connecting tubes 21 can pass through the first channel, meaning the round tube at the bottom of the foldable bracket 2 can be sequentially inserted into the hole formed by the bottom support buckle 12 and the bottom support ear 13, the hole on the bottom support ear 13, and the inner cylinder on the support base 14. Then, after the bottom support buckle 12 is tightened with bolts, it can cooperate with the bottom support ear 13 to clamp the bottom of the first connecting tube 21. Additionally, the cylindrical sidewall of the support base 14 has holes that cooperate with the first connecting tubes 21. After the first connecting tube 21 is inserted, it can be positioned using a spring pin. The second connecting tube 22 is a short horizontal tube. Similarly, the number of second connecting tubes 22 can be set according to actual needs. In this embodiment, no specific limitation is made. In this embodiment, it is preferred that there are three second connecting tubes 22. The second connecting tubes 22 are vertically distributed at the short side of the isosceles trapezoid, that is, the three second connecting tubes 22 are vertically distributed along the length of two of the first connecting tubes 21 and located between the two first connecting tubes 21. The third connecting tube 23 is a long horizontal tube. Similarly, the number of third connecting tubes 23 can be set according to actual needs. In this embodiment, no specific limitation is made. In this example, it is preferred that there are three third connecting pipes 23. The three third connecting pipes 23 are vertically distributed along the long side of the isosceles trapezoid, that is, three third connecting pipes 23 are vertically distributed along the length of the other two first connecting pipes 21, and located between the other two first connecting pipes 21. The fourth connecting pipe 24 is a connecting short pipe. Similarly, the number of fourth connecting pipes 24 can be set according to actual needs; this embodiment does not impose a specific limitation. In this embodiment, it is preferred that there are six fourth connecting pipes 24. As mentioned above, it is preferred that both the second connecting pipe 22 and the third connecting pipe 23 are three in each embodiment. Therefore, in each second connecting pipe 22 and the third connecting pipe 23... At the position of the isosceles trapezoid formed by the three connecting pipes 23, two fourth connecting pipes 24 are distributed between the second connecting pipe 22 and the third connecting pipe 23; the fifth connecting pipe 27 is an oblique connecting pipe. Similarly, the number of fifth connecting pipes 27 can be set according to actual needs. In this embodiment, no specific limitation is made. In this embodiment, it is preferred that there are two fifth connecting pipes 27. That is, one fifth connecting pipe 27 is installed at each of the two oblique sides of the isosceles trapezoid at the top of the frame. Thus, the overall structure of the frame is formed by multiple first connecting pipes 21, multiple second connecting pipes 22, multiple third connecting pipes 23, multiple fourth connecting pipes 24, and multiple fifth connecting pipes 27.

[0051] Furthermore, such as Figure 6 , Figure 8 , Figure 9 , Figure 10 , Figure 11 As shown, the foldable bracket 2 also includes: connectors, including a tee connector 26, a straight connector 25, a spring pin, a support block 29, and a second pulley block 28. Specifically: mounting holes are provided at the connection positions of the first connecting pipe 21, the second connecting pipe 22, the third connecting pipe 23, the fourth connecting pipe 24, and the fifth connecting pipe 27. That is, the first connecting pipe 21 has holes at its top, middle, and near its end that mate with the tee connector 26. When the tee connector 26 is inserted into the first connecting pipe 21, the spring pin can be inserted into the corresponding hole to achieve axial and radial positioning. The second connecting pipe 22 has a hole near its middle that mates with the tee connector 26. When the tee connector 26 is inserted into the second connecting pipe 22, the spring pin can be inserted into the corresponding hole to achieve axial and radial positioning. At the same time, there are holes at both ends of the second connecting pipe 22 that mate with the straight connector 25. After the horizontal short tube 22 is inserted, a spring pin can be inserted into the corresponding hole to achieve axial and radial positioning; the third connecting tube 23 has a hole near the middle that mates with the tee connector 26. When the tee connector 26 is inserted into the third connecting tube 23, a spring pin can be inserted into the corresponding hole to achieve axial and radial positioning. The third connecting tube 23 has holes at both ends that mate with the straight connector 25. When the straight connector 25 is inserted into the third connecting tube 23, a spring pin can be inserted into the corresponding hole to achieve axial and radial positioning; the fourth connecting tube 24 has holes at both ends that mate with the straight connector 25. When the straight connector 25 is inserted into the fourth connecting tube 24, a spring pin can be inserted into the corresponding hole to achieve axial and radial positioning; the fifth connecting tube 27 has holes at both ends that mate with the straight connector 25 and the support block 29. When the fifth connecting tube 27 is inserted into the straight connector 25 and the support block 29, a spring pin can be inserted into the corresponding hole to achieve axial and radial positioning.

[0052] Furthermore, such as Figure 7As shown, the support block 29 is set at the top of the frame. The support block 29 has a first through hole. That is, the two support blocks 29 are installed on the two fifth connecting pipes 27 respectively. Then, the second pulley group 28 is installed on the support block 29. In this embodiment, it is preferred that the number of pulleys in the second pulley group 28 is 4. Thus, each support block 29 is equipped with four pulleys 28. During subsequent installation, after the square splicing column 31 of the support column 3 is inserted into the inner hole of the support block 29, the pulleys 28 on both sides will limit, support and reduce friction on the square splicing column 31. After the tubes and corresponding connectors are assembled, each straight connector 25 can be hinged according to the drawings and the corresponding tee connector 26. The straight connector 25 and the tee connector 26 have corresponding holes. When the straight connector 25 is inserted into the corresponding slot of the tee connector 26, the spring pin can be inserted into the corresponding hole to achieve hinge and positioning. Finally, the two ends of the fourth connecting tube 24 are hinged to the second connecting tube 22 and the third connecting tube 23, respectively. The second connecting tube 22, the third connecting tube 23 and the fifth connecting tube 27 are hinged to the first connecting tube 21. When the corresponding positioning spring pin is pulled out, the foldable bracket 2 can be quickly folded and stored. The bottoms of the four first connecting tubes 21 are sequentially inserted into the holes formed by the bottom support buckle 12 and the bottom support ear 13, the holes on the bottom support ear 13, and the inner cylinder on the support base 14 to achieve the nested connection between the foldable bracket 2 and the base 1. Then, the bottom support buckle 12 is tightened with bolts to cooperate with the bottom support ear 13 to hold the four first connecting tubes 21. In addition, there are holes on the cylindrical side wall of the support base 14 that cooperate with the bottom of the vertical tube 21, which can be positioned by spring pins, and finally the connection between the foldable bracket 2 and the base 1 is achieved.

[0053] Multiple support columns 3 are inserted from top to bottom into the first through hole and then fixedly connected to the base 1. The support column 3 includes: a splicing column 31, which includes at least two column segments that are detachably connected; and a first pulley group 33, which is fixed to the top of the splicing column 31.

[0054] Furthermore, the support column 3 also includes: an adapter plate 34, with threaded holes at both ends of the splicing column 31, and bolts engaging with the threaded holes to connect the splicing column 31 to the first pulley group 33 via the adapter plate 34; and a rope limiter 32, which is fixed to the adapter plate 34 by bolts.

[0055] Specifically, the number of support columns 3 can be set according to actual needs, and this embodiment does not impose a specific limitation. However, in this embodiment, two support columns 3 are preferred. Figure 2 , Figure 3 , Figure 12 , Figure 13As shown, the support column 3 includes: a splicing column 31, a first pulley group 33, an adapter plate 34, and a rope limiter 32. Specifically, the splicing column 31 includes at least two detachably connected column segments, that is, the splicing column 31 is composed of multiple column segments spliced ​​together, and in this embodiment, the number of column segments is preferably four. That is, four splicing columns 31 are spliced ​​and fixed together vertically to form the main body of the support column 3. At the same time, threaded holes are drilled at both ends of the splicing column 31, and the pulley 33 can be fixed to the top of the splicing column 31 by bolts through the adapter plate 34. In this embodiment, the number of pulleys in the first pulley group 33 is preferably two. Furthermore, the rope limiter 32 is fixed to the adapter plate 34 by bolts. When the rope crosses the first pulley group 33, the rope limiter 32 is close to the pulley 33, so that the rope will not slip out of the U-shaped groove of the pulley. The support column 3 is composed of multiple splicing columns 31, and the height can reach 6m. After the support column 3 passes through the first through hole in the support block 29 from top to bottom, it falls on the connecting column 11 and is fixed to the connecting column 11 by the L-shaped angle aluminum connector. At this time, the bottom end of the support column 3 is connected to the base 1, and the middle part is limited by the support block 29 of the foldable bracket 2, so as to maintain an upright posture.

[0056] A conformal circular sleeve 4 is fitted onto the splicing column 31. The conformal circular sleeve 4 includes: multiple hollow circular rings 41, with multiple first steel wire ropes 42 connected between every two hollow circular rings 41.

Specifically, the number of hollow circular rings 41 can be set according to actual needs, and there is no specific limitation in this embodiment. However, in this embodiment, a number of eight hollow circular rings 41 is preferred. In other words, since there are two support columns 3, four hollow rings 41 are fitted in the vertical direction of each support column 3; multiple first steel wire ropes 42 are connected between every two hollow rings 41, and the multiple first steel wire ropes 42 are evenly distributed. A covering cloth can be laid on the outside of the first steel wire ropes 42, and the covering cloth can be attached to the hollow rings 41 with Velcro. The evenly spaced steel wire ropes provide support and plasticity for the covering cloth. The hollow rings 41 are connected and fixed to the sleeve lugs 48 through ring adapters 49.

Furthermore, the contoured annular sleeve 4 is fitted onto the splicing column 31 of the support column 3 via sleeve 47, so that the bullseye ball 43 and mini bearing 45 can directly contact the splicing column 31, allowing the contoured annular sleeve 4 to move up and down on the support column 3.

[0060] Support rod 5, which is disposed between the two support columns 3;

[0061] Furthermore, the support rod 5 includes: a support tube 51, with mounting holes at both ends, through which the support tube 51 can be connected to the straight connector 25, and the straight connector 25 can be inserted into the support tube 51 and positioned axially and radially by inserting a spring pin into the corresponding hole; and a support connector 52, which is fixedly mounted on the splicing column 31, and has a mounting groove, through which the straight connector 25 can be hinged and positioned by inserting a spring pin when inserted into the mounting groove.

[0062] Specifically, support rod 5 is located at the top of the missile launch tube decoy, such as... Figure 17 , Figure 18 As shown, the support rod 5 includes: a support tube 51, a support connector 52, and a straight connector 25. Specifically, the support tube 5 has mounting holes at both ends, which can mate with the holes of the straight connector 25. Thus, the support tube 51 can be connected to the straight connector 25 through the mounting holes. After the straight connector 25 is inserted into the support tube 51, a spring pin can be inserted into the corresponding hole to achieve axial and radial positioning. The straight connector 25 and the support connector 52 have corresponding holes. The support connector 52 has a mounting groove. When the straight connector 25 is inserted into the corresponding groove of the support connector 52, a spring pin can be inserted into the corresponding hole to achieve hinge and positioning. The support connector 52 is finally fitted onto the splicing column 31 in the support column 3 and fixed with bolts. The entire top support rod 5 is finally connected to the two support columns 3 on both sides.

[0063] Furthermore, one end of the second wire rope is fixedly connected to the bolt eye 410 on the top sleeve 47, and after passing through the first pulley block 33, the other end is fixedly connected to the hand-cranked winch. When the hand-cranked winch pulls one end of the second wire rope, the other end of the second wire rope drives the uppermost contoured circular sleeve 4 to rise on the support column 3 until the covering cloth is fully unfolded into a cylindrical shape.

[0064] Specifically, one end of a steel wire rope passes through the first pulley block 33 and is fixedly connected to the bolt eye 410 on the short side of the sleeve 47 of the uppermost contoured circular sleeve 4. The other end is connected to a hand-cranked winch. When one end of the steel wire rope is pulled by the hand-cranked winch, the other end of the steel wire rope causes the uppermost contoured circular sleeve 4 to rise on the support column 3. Because of the presence of equidistant steel wire ropes 42, the contoured circular sleeve 4 will rise continuously until the outer covering is fully unfolded into a cylindrical shape.

[0065] Therefore, the vertical missile launch tube dummy target in this embodiment, which can be quickly folded and unfolded, has a base, a foldable bracket, a support column, a contoured circular sleeve, and a top support rod connected in sequence. The base, foldable bracket, and top support rod provide support and positioning for the support column. The foldable bracket can be quickly unfolded and retracted, making it flexible, convenient, and easy to store. The main body of the support column is composed of multiple sections, reaching a maximum length of 6m, which can completely simulate the length of a missile launch tube. The contoured circular sleeve can be raised and lowered on the support column under the traction of a rope. When unfolding, the foldable bracket is unfolded and positioned with a spring pin, then the support column is installed, the circular sleeve is fitted, the top support rod is installed, and a hand-cranked winch is used to lift the circular sleeve via a rope. The circular sleeve is covered with a cloth to simulate the texture and color of a missile launch tube. During retrieval, the rope can be loosened and gradually lowered, allowing the circular sleeve to slowly fall to the bottom under its own weight. Then, the circular sleeve and support column can be removed in sequence, and the foldable bracket can be folded to complete the disassembly and storage of the device. This achieves the technical effects of high realism in appearance, quick loading, unloading and lifting, simple structure, flexible operation, and overall stability. It solves the problems of existing missile launch tube dummy target tubes having low realism in appearance, difficulty in overall disassembly and assembly, low strength, poor stability, poor durability, and being unsuitable for long-term use and inconvenient to disassemble and assemble.
