[0023] In order to further understand the content, features and effects of the present invention, the following embodiments are given to explain in detail.

[0024] See also Figure 1The multifunctional adjustable rocket launching device of the present invention comprises a base plate 7, on which four adjusting leg assemblies 6 are mounted, a launching platform assembly 4 is mounted above each adjusting leg assembly 6, a slewing assembly 3 with controllable slewing rotation is mounted in the middle of the launching platform assembly 4, a plurality of rocket body supporting assemblies 1 are mounted on the slewing assembly 3, and a plurality of clamping and fixing assemblies 2 for fixing the slewing assembly 3 are also mounted on the launching platform assembly 4.

[0025] Among them, the bottom plate 7 is used as the mounting base of the upper components, and a plurality of connection holes are provided on the bottom plate 7. When the rocket launch device is used, it is fixed to the ground with anchor nails to ensure the overall stability. The launch platform assembly 4 is supported by each adjustment leg assembly 6, and each adjustment leg assembly 6 can independently adjust the height, so that the launch platform assembly 4 can be leveled and can also be adjusted to a certain launch angle (that is, there is a certain angle between the surface of the launch platform assembly 4 and the horizontal plane). Multiple rocket body support assemblies 1 are used to support the rocket body, and the slewing assembly 3 is used for controllable slewing rotation. By operating the slewing assembly 3, the shooting direction of the rocket can be adjusted and set.

[0026] As shown in the figure, there are four rocket body support assemblies 1 arranged at equal angles in the circumferential direction. The rocket body support assembly 1 includes a supporting crossbeam fixedly connected to the rotating assembly 3, a supporting longitudinal beam is installed at the inner end of the supporting crossbeam, a supporting oblique beam is provided between the supporting crossbeam and the supporting longitudinal beam, and a connecting block that cooperates with the connecting structure on the rocket body is provided at the top of the supporting longitudinal beam.

[0027] In order to load rocket bodies of different diameters, the radial position of each body support assembly 1 on the rotary assembly 3 can be adjusted and set. When each body support assembly 1 moves outward synchronously, the diameter of the rocket body to be loaded increases. Conversely, when each body support assembly 1 moves inward synchronously, the diameter of the rocket body to be loaded decreases. Furthermore, the connecting piece at the top of each body support assembly 1 is fixedly connected to the supporting longitudinal beam by bolts, so that the connecting block can be selected and replaced according to the different types of connection structures on the rocket body.

[0028] See also Figure 1 , we can see that:

[0029] The launching platform assembly 4 comprises a rectangular supporting platform with pillars installed below the four corners of the supporting platform, and reinforcing diagonal bracing beams installed between the pillars and the supporting platform to ensure the overall structural strength, and the lower end of each pillar is fixedly connected to the upper end of the corresponding adjusting leg assembly 6.

[0030] A window is provided in the middle of the supporting platform of the launching platform assembly 4 for the rocket tail flame to pass through, and the rotating assembly 3 is located above the window.

[0031] See also Figure 2and Figure 3 , we can see that:

[0032] The slewing assembly 3 includes a slewing gear plate 31 and a pinion 33 meshingly connected with the slewing gear plate 31. The pinion 33 has a gear shaft 32 that can be driven to rotate by a tool. A plurality of base plates 36 of annular splicing are installed on the slewing gear plate 31. The base plates 36 are fixedly connected to the slewing gear plate 31 by screws. Each arrow body support assembly 1 is installed and fixed on the base plate 36. When the gear shaft 32 is driven by a tool such as an open-end wrench to drive the pinion 33 to rotate, the slewing gear plate 31 is driven to rotate, thereby realizing controllable slewing control. It can be imagined that there is a window in the middle of the slewing gear plate 31 for the rocket tail flame to pass through, and correspondingly, a window for the rocket tail flame to pass through is also formed in the middle of each base plate 36.

[0033] In the present embodiment, the supporting crossbeam of the rocket body supporting assembly 1 is fixedly connected to the base plate 36 of the rotating assembly 3 by bolts, and a plurality of mounting holes are provided in the radial direction at the mounting position of each rocket body supporting assembly 1. Thus, when the rocket body supporting assembly 1 needs to be radially shifted and adjusted, it is only necessary to first remove the connecting screws between the supporting crossbeam and the base plate 36, move the rocket body supporting assembly 1 inward or outward, and then re-screw in the screws to fix it.

[0034] As shown in the figure, a gear mounting base plate 35 is fixedly installed on the supporting platform of the launching platform assembly 4, an axis groove is provided in the middle of the gear mounting base plate 35 and the lower end of the rotating shaft of the pinion gear 33 is located in the axis groove, and a pinion gear housing 34 is also installed on the gear mounting base plate 35, the pinion gear 33 is located inside the pinion gear housing 34 and the upper end of its rotating shaft passes through the axis hole on the top wall of the pinion gear housing 34.

[0035] See also Figure 2 , we can see that:

[0036] The clamping and fixing assembly 2 includes a clamping block base 23 installed and fixed on the supporting platform of the launching platform assembly 4, a clamping block 21 is hingedly installed on the top of the clamping block base 23 through a hinge shaft 24, and a clamping adjustment bolt 22 with a handle is also installed on the outer end of the clamping block 21, the lower end of the clamping adjustment bolt 22 abuts against the clamping block base 23, and the inner end of the clamping block 21 is pressed on the edge of the base plate 36 of the rotating assembly 3.

[0037] Specifically, as shown in the figure, the clamping block base 23 has an ear plate with an axial hole, and a window is provided in the middle of the clamping block 21. The upper end of the ear plate of the clamping block base 23 is located in the window and is hingedly connected by a hinge shaft 24. A threaded hole is provided at the outer end of the clamping block 21, and a clamping adjustment bolt 22 is located in the threaded hole. The clamping adjustment bolt 22 is rotated by a handle to make it rise or fall. When the clamping adjustment bolt 22 moves toward the clamping block base 23, due to the principle of leverage, the outer end of the clamping block 21 is lifted, the inner end is lowered and pressed on the edge of the base plate 36 of the rotating assembly 3, thereby fixing the entire rotating assembly 3.

[0038] There are multiple clamping and fixing assemblies 2 in the circumferential direction. In addition to providing the clamping and fixing function, another function is to limit the inner rotating gear disc 31, that is, the rotating gear disc 31 is limited to the inner side of the clamping block base 23 of each clamping and fixing assembly 2.

[0039] See also Figure 5 , we can see that:

[0040] The leg adjustment assembly 6 includes a support base 64, a lifting adjustment bolt 63 and a lifting sleeve 62. The lifting sleeve 62 is threadedly connected to the lifting adjustment bolt 63. The lower end of the lifting adjustment bolt 63 is connected to the support base 64 by a ball joint assembly 67. A lower connection cover 66 is installed at the bottom of the lifting sleeve 62. An upper flange connection cover 61 is installed above the lower connection cover 66 through a plurality of columns 65. The upper flange connection cover 61 is fixedly connected to the launch platform assembly 4, and the support base 64 is fixedly connected to the bottom plate 7.

[0041] In this embodiment, a flange is provided at the lower end of the pillar of the launch platform assembly 4 and the flange is connected to the upper flange connection cover 61 of the corresponding adjustment leg assembly 6 by bolts. The bottom of the support base 64 has a flange and the flange is fixedly connected to the base plate 7 by bolts.

[0042] The ball joint assembly 67 is composed of a ball head part and a ball sleeve part, wherein the ball head part is fixedly mounted on the lower end of the lifting adjustment bolt 63, and the ball sleeve part is fixedly mounted on the upper end of the support base 64. The use of the ball joint assembly 67 to connect the lifting adjustment bolt 63 and the support base 64 has the following functions: first, the lifting adjustment bolt 63 can be rotated under the operation of a wrench or other tools. At this time, due to the threaded connection between the lifting adjustment bolt 63 and the lifting sleeve 62, the lifting sleeve 62 and its attached parts are lifted and moved while the height of the lifting adjustment bolt 63 remains unchanged, thereby achieving height adjustment of the adjustment leg assembly 6; secondly, when the four adjustment leg assemblies 6 are individually adjusted in height, the angle of the launch platform assembly 4 can be adjusted, and the shooting direction can be adjusted. At this time, the adjustment leg assembly 6 undergoes adaptive bending deformation at the position of the ball joint assembly 67, thereby ensuring the operability of the shooting direction adjustment.

[0043] In this embodiment, a protective baffle 9 is also installed on the bottom plate 7 to prevent the rocket tail flame from spraying onto the adjustable leg assembly 6, and each protective baffle 9 is located on the inner side of each adjustable leg assembly 6.

[0044] A guide component 5 is also installed in the middle of the bottom plate 7. The guide component 5 is located below the aforementioned rocket tail flame window. The tail flame generated when the rocket is launched passes through the window and is sprayed onto the guide component 5. The guide component 5 can discharge the tail flame to the side, which helps to protect the launch device and avoid the adverse effect of the tail flame backflow on the rocket launch.

[0045] See also Figure 4 , we can see that:

[0046] The guide assembly 5 includes two opposite side panels 54, each of which is fixedly connected to the bottom plate 7 by a mounting seat 53 located on the outside. The mounting seat 53 is bolted to the outside of the bottom edge of the side panel 54 and fixedly connected to the bottom plate 7 by bolts. A guide cone 52 with an arc surface is installed between the two side panels 54, and a guide strip block 51 is provided on the top of the guide cone 52. The two ends of the guide strip block 51 are detachably connected to the two side panels 54.

[0047] Specifically, the guide cone 52 can be composed of two opposite arc-shaped guide plates, the edges of the two guide plates are respectively welded to the two side plates 54, and the two guide plates constitute a ridge-shaped guide cone 52. The rocket tail flame is discharged to the sides along the two sides of the guide cone 52.

[0048] The purpose of setting the guide bar block 51 to be detachable is that the guide bar block 51 is a part that is easily ablated. By making the guide bar block 51 detachable, it becomes a structure that is easy to replace, which satisfies the effect of convenient and low-cost repair for high-efficiency launch missions. As shown in the figure, connection holes are provided at the tops of the two side plates 54, and correspondingly, connection holes are also provided at the ends of the guide bar block 51, and the ends of the guide bar block 51 are fixedly connected to the side plates 54 by screws.

[0049] In this embodiment, an instrument bracket 8 is also installed on the slewing assembly 3. The instrument bracket 8 is a bracket rod installed on the base plate 36, and both ends of the bracket rod extend to the outside of the launch platform assembly 4. A shooting alignment tool or a total station can be installed on the instrument bracket 8 to achieve the function of aligning the shooting line.
