DETAILED DESCRIPTION

[0025] The scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. In addition, the descriptions of "first", "second", etc. in the utility model are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features.

[0026] In view of the technical defects existing in the related art, the utility model provides a demonstration device simulating rocket launch, please refer to Figures 1 to 3, including: a rocket body 100, a launching platform 200, an adaptor 400 and a guide column 500, wherein the launching platform 200 is used to carry the rocket body 100 for launching, so the launching platform has a carrying surface 210 for carrying the rocket body 100, and at this time the carrying surface 210 can be set in a square plane, a circular plane, or a plane of other shapes, which is not specifically limited here.

[0027] Furthermore, the leveling device 300 is connected to the launch platform 200 and is used to level the bearing surface 210; with such a configuration, the leveling device 300 can level the bearing surface 210 that supports the rocket body 100, so that the rocket body 100 is in a horizontal and upright state before launch, thereby avoiding the rocket body 100 from tilting before launch.

[0028] It should be noted that the leveling device 300 has many structures for leveling the bearing surface 210. For example, a plurality of pillars are convexly provided on the side of the launch platform 200 facing away from the bearing surface 210, and the pillars are arranged at intervals along the circumference of the launch platform 200. A threaded hole is concavely provided on the side of each pillar away from the bearing surface 210. The leveling device 300 includes a plurality of bolts, and each bolt is threadedly connected to a corresponding threaded hole. The leveling of the bearing surface 210 can be achieved by adjusting the bolts.

[0029] For example, in this embodiment, please refer to Figure 2 and Figure 3 The launch platform 200 is provided with at least three first threaded holes 220 penetrating therethrough, and each first threaded hole 220 is arranged at intervals along the circumference of the launch platform 200. The leveling device 300 includes at least three bolts 310, and each bolt 310 is threadedly connected with the corresponding first threaded hole 220; thus, the user can directly screw each bolt 310 arranged on the launch platform 200 from top to bottom to achieve the leveling of the bearing surface 210. In addition, in order to make it more convenient for the user to perform leveling, a concave and convex anti-slip handle is also provided on the top of each bolt 310.

[0030] One end of the adapter 400 is fixedly connected to the launch platform 200, and the other end of the adapter 400 can be retracted in the horizontal direction toward or away from the rocket body 100; in addition, the side of the rocket body 100 is provided with a guide tube 110 extending in the up-down direction, and the guide column 500 is installed at one end of the adapter 400 adjacent to the rocket body 100, and the guide column 500 at least partially extends into the guide tube 110. With such a configuration, the rocket body 100 has a vertical upward guide before launch, further avoiding the rocket from tilting after launch; in addition, the adapter 400 can also be retracted toward or away from the rocket body 100, so that the launch platform 200 can adapt to rockets of different diameters, and has high compatibility.

[0031] In order to facilitate the adapting device 400 to achieve telescopic movement toward or away from the rocket body 100, in this embodiment, the adapting device 400 includes a fixed sleeve 410 and a slider 420. The fixed sleeve 410 is horizontally mounted on the bearing surface 210, and the slider 420 is slidably mounted in the fixed sleeve 410. One end of the slider 420 is connected to the guide column 500. The telescopic setting of the adapting device 400 can be achieved by slidingly connecting the slider 420 and the fixed sleeve 410.

[0032] Considering that the bottom of the rocket body 100 is generally used for igniting gunpowder spray, the guide column 500 provided thereon will be sprayed with gunpowder, which may easily cause damage to the guide column 500. In view of this, in this embodiment, the fixed sleeve 410 includes a sliding section 411 provided in the horizontal direction and a fixed section 412 provided in the vertical direction, one end of the fixed section 412 is connected to the bearing surface 210, the other end of the fixed section 412 is connected to the sliding section 411, and the slider 420 is slidably connected to the sliding section 411. In this way, after the guide column 500 is provided on the slider 420, it is away from the bearing surface 210 and will not be sprayed when igniting gunpowder.

[0033] In addition, considering that the lengths of the rocket body 100 are different, the heights of the guide tubes 110 provided on the side of the rocket body 100 from the bearing surface 210 are different. In this way, the guide column 500 is easily unable to extend into the guide tube 110 for guidance due to insufficient height. In view of this, in order to avoid the guide column 500 being unable to extend into the guide tube 110 due to insufficient height, in some embodiments, a second threaded hole 421 is provided at one end of the slider 420 away from the fixed sleeve 410, and the guide column 500 has a threaded section 510 and a guide section 520. The threaded section 510 is threadedly connected to the second threaded hole 421, and the guide section 520 at least partially extends into the guide tube 110. In this way, the guide column 500 can be extended and retracted up and down relative to the slider 420, avoiding the problem that the guide column 500 cannot be guided due to the excessive height of the guide tube 110.

[0034] In some embodiments, see Figure 4 In order to prevent the slider 420 from falling out of the sliding section 411, the sliding section 411 is provided with a guide groove 411a along the sliding direction of the slider 420, and the slider 420 is provided with a positioning hole 422 corresponding to the guide groove 411a. The adapter 400 also includes a positioning column 430, which passes through the guide groove 411a and is plugged into the positioning hole 422. At least part of the positioning column 430 is located in the guide groove 411a. In this way, under the positioning of the positioning column 430, the slider 420 can fall out of the sliding section 411.

[0035] In order to facilitate the user to level the bearing surface 210, in this embodiment, the demonstration device for simulating rocket launch further includes at least three liquid level gauges 600, each of which is arranged on the bearing surface 210 at intervals along the circumference of the launch platform 200. It should be noted that the number of the liquid level gauges 600 can also be four, five, or more, and the user can observe through multiple liquid level gauges 600 to facilitate the user to level the bearing surface 210 of the launch platform 200.

[0036] In some embodiments, the launch platform 200 is provided with a circle of annular bosses 230 distributed along its circumference, and each liquid level gauge 600 is located outside the annular bosses 230. In this way, when the rocket body 100 is launched, the annular bosses 230 can prevent the gunpowder from being sprayed onto the bearing surface 210 and then sprayed around, ensuring that the spectators will not be splashed by sparks when observing the rocket launch demonstration.

[0037] In addition, considering that the launch platform 200 may be shot through and damaged due to excessive heat from gunpowder during launch of the rocket body 100, the launch platform 200 may be made of a higher-strength metal material, such as stainless steel, aluminum alloy, etc., and a heat-insulating coating may be coated on its surface to prevent the launch platform 200 from overheating after the rocket body 100 is launched.

[0038] See also Figure 5 and Figure 6 In some embodiments, the rocket body 100 includes a rocket head 120, a fuselage 130, a powder keg 140 and a parachute 150, wherein the fuselage 130 is arranged in a cylindrical shape with both ends open, the guide tube 110 is installed on the outer wall of the fuselage 130, the rocket head 120 is installed at the upper end of the fuselage 130 and covers the upper end opening of the fuselage 130, the powder keg 140 is installed at the lower end of the fuselage 130 and covers the lower end opening of the fuselage 130, the powder keg 140 has an injection end, and the injection end is arranged facing the lower end opening of the fuselage 130, and the parachute 150 is connected to the rocket head 120 and installed in the fuselage 130.

[0039] In the teaching of simulated rocket launch, a parachute 150 is also set in the rocket body 100. The rocket body 100 rises to the highest point and then falls. Due to the weight difference between the fuselage 130 and the rocket head 120, the fuselage 130 and the rocket head 120 disintegrate and separate in the air, and the parachute 150 tied to the rocket head 120 will be released from the fuselage 130, causing the rocket head 120 to slowly land, making it convenient for viewers to observe.

[0040] In addition, in order to prevent the gunpowder barrel 140 from being overheated during the launch of the rocket body 100 and causing the parachute 150 disposed in the fuselage 130 to burn, in some embodiments, the rocket body 100 further includes a heat insulation board 160, which is located between the gunpowder and the parachute 150. The heat insulation board 160 can be a heat insulation mud board, a heat insulation ceramic board, or other materials capable of isolating heat.
