Detailed description of the invention
As shown in Figure 1, the rocket model being easy to reclaim of the present utility model, comprise upper shell 1 and lower house 4, described upper shell 1 is inserted in lower house 4, described upper shell 1 internal fixtion has one piece of fixed block 2, a closed parachute 5 is provided with in described lower house 4, line 3 is provided with between described fixed block 2 and parachute 5, also line 3 is provided with between the bottom of described parachute 5 and the inner surface of lower house 4, the bottom of described lower house 4 is fixed with support 9, the bottom of described lower house 4 is fixed with a recoil grain 7, the below of described recoil grain 7 is fixed with a driving grain 8, all gunpowder is placed with in described recoil grain 7 and driving grain 8, the first blasting fuse 10 is connected with between described recoil grain 7 and driving grain 8, the bottom of described driving grain 8 is connected with the second blasting fuse 14, described second blasting fuse 14 stretches out in outside lower house 4, the bottom of described lower house 4 is fixed with a backstay 11, the bottom of described backstay 11 is connected with spring 12, the end of described spring 12 is connected with a locating piece 13, the upper surface of described locating piece 13 abuts on the bottom surface of driving grain 8, button cell 16 is provided with in described upper shell 1, the outer surface of described upper shell 1 is provided with several LED 15 and shift knob 17, after several LED 15 described are in parallel and shift knob 17 and button cell 16 be in series, the top of described upper shell 1 is conical, the outer wall of described lower house 4 is evenly equipped with several balance wing 6.
Rocket model with parachute of the present utility model, structure is simple, when launching, light the second blasting fuse 14, the gunpowder in grain 8 is then driven to take fire, thus drive whole rocket model to complete transmitting, when rocket model is emitted to peak time, the gunpowder in grain 8 is driven to be lighted by the grain in recoil grain 7 by the first blasting fuse 10, gunpowder in recoil grain 7 burns, the gas produced after its burning produces an impulsive force upwards, under the effect of impulsive force, upper shell 1 is separated with lower house 4, parachute 5 is also deviate from from lower house 4 and is trailed, upper shell 1, parachute 5 and lower house 4 are linked together by line 3, and upper shell 1 and lower house 4 are in the process of falling, due to the existence of parachute 5, lapse rate can be reduced greatly, thus avoid upper shell 1 and lower house 4 to break in the process fallen, guarantee that upper shell 1 and lower house 4 can reuse, thus substantially increase the utilization rate of resource.
The bottom of lower house 4 is fixed with a backstay 11; the bottom of backstay 11 is connected with spring 12; the end of spring 12 is connected with a locating piece 13; the upper surface of described locating piece 13 abuts on the bottom surface of driving grain 8; thus drive grain 8 in the process of launching; due to firm driving grain 8 is blocked of locating piece 13 energy, thus can avoid driving grain 8 to come off, guarantee rocket model energy normal transmission.
The top of upper shell 1 is conical; the outer wall of described lower house 4 is evenly equipped with several balance wing 6; thus can guarantee that rocket model bears less air drag in the process of launching, simultaneously under the effect of balance wing 6, keep rocket model to be in poised state.
Fire a rocket before model, shift knob 17 is pressed, start LED 15, make LED 15 luminous, so, when rocket model battery has fired and Crater face time, the light sent by LED 15, be easy to the upper shell 1 after finding rocket model transmitting and lower house 4, very convenient.
