[0002] With the continuous progress of science and technology, the construction and construction technology of rockets in the field of space technology in China are also developing and progressing, so that more students have a strong interest in the launch of rockets, at present, the rocket launch control device mostly is that the cantilever of tower frame is expanded manually first, then the ejection of rocket is controlled, the expansion and folding of the cantilever of tower frame is completely relied on manual operation, which is far from the real rocket launch, so that the rocket launch demonstration effect is poor. SUMMARY

[0003] Therefore, the utility model aims at overcoming the defects in prior art, and provides a launch control device.

[0004] The utility model provides a launch control device, including base 1 and bottom box 2, the bottom of base 1 is provided with control module 6, the servo motor 7 of electric connection with control module 6, the output shaft of servo motor 7 is keyed with drive gear 8, the bottom of base 1 is transversely slidably equipped with the gear 9 of drive gear 8 drive, the upper end of base 1 is vertically provided with tower frame 3, the cantilever 4 of drive expansion, folding of gear 9 drive is rotatably arranged on tower frame 3, the elastic column 5 of gear 9 drive is ejected and is elastically arranged on base 1.

[0005] Further, the gear 9 is composed of the upper double-sided rack and the lower single-sided rack, the single-sided rack is engaged with the drive gear 8, and the bottom of the double-sided rack is provided with a push block.

[0006] Further, the cantilever 4 is keyed with a long shaft rotating on the tower frame 3 and the base 1, and the lower end of the long shaft is keyed with a driven gear 10 engaged with the double-sided rack.

[0007] Further, the lower end of the elastic column 5 is provided with an annular protrusion, the elastic column 5 is connected with the bottom box 2 through an elastic member, and a limiting rod 11 is twisted on the base 1 for limiting the annular protrusion and being pushed by the push block.

[0008] Further, the upper end of the limiting rod 11 is provided with an inclined surface 11.1.

[0009] Further, the outer wall of the base 1 is provided with a display screen 12 electrically connected with the control module 6.

[0010] The advantages of this invention are: it can automatically extend and retract the cantilever, and after the cantilever extends, it drives the projectile to launch the rocket, improving the rocket demonstration effect; the drive gear controlled by the servo motor drives the gear component to move to the right, and the racks on both sides of the gear component drive the driven gears on both sides to rotate. The driven gears drive the cantilever to extend through the long shaft. After the projectile is launched and pressed back by the rocket, the drive gear drives the cantilever to retract and reset through the racks; when the push block of the gear component moves to the right, the push block pushes the limit rod and makes it rotate, and the limit rod releases the ring of the projectile. The rocket is launched by a protrusion and a spring-loaded protrusion. The bottom of the base has a stepped hole, which stops the ejected protrusion. After the protrusion is pushed back by the rocket, the push block of the gear moves to the left and resets. The limiting rod that is disengaged from the push block resets to limit the protrusion, keeping it in a state of elasticity ready for launch. After the protrusion is launched, the pushed-back protrusion can be pushed open by the inclined surface. Then, the limiting rod resets under the action of the torsion spring and limits the annular protrusion. The display screen controlled by the control module can display the countdown and launch command. Attached Figure Description
