Description
Technical field
The utility model relates to a kind of space flight equipment model, particularly a kind of rocket model with parachute.
Background technology
Current existing rocket model, because the speed fallen in the process of falling after its transmitting is very fast, easily the housing of rocket model is broken, thus be generally all disposable, the wasting of resources is comparatively serious, in addition, rocket model is in the process of launching, due to grain can not be firm be fixed in rocket model, thus easily to come off from rocket model, cause rocket model can not succeed in sending up to specified altitude assignment.
Summary of the invention
Problem to be solved in the utility model is: provide that a kind of structure is simple, balanced capacity is strong and can significantly reduce rocket model lapse rate so can reuse the rocket model with parachute of the housing of rocket model.
In order to solve the problem, rocket model with parachute of the present utility model, comprise upper shell and lower house, described upper shell is inserted in lower house, described upper shell internal fixtion has one piece of fixed block, a closed parachute is provided with in described lower house, line is provided with between described fixed block and parachute, line is provided with between the bottom of described parachute and the inner surface of lower house, the bottom of described lower house is fixed with support, the bottom of described lower house is fixed with a backpulsing grain, the below of described recoil grain is fixed with a driving grain, all gunpowder is placed with in described recoil grain and driving grain, the first blasting fuse is connected with between described recoil grain and driving grain, the bottom of described driving grain is connected with the second blasting fuse, described second blasting fuse stretches out in outside lower house, the bottom of described lower house is fixed with a backstay, the bottom of described backstay is connected with spring, the end of described spring is connected with a locating piece, the upper surface of described locating piece abuts on the bottom surface of driving grain.
In order to guarantee that rocket model bears less air drag in the process of launching, make rocket model be in poised state simultaneously; Rocket model with parachute of the present utility model, the top of described upper shell is conical, the outer wall of described lower house is evenly equipped with several balance wing.
The beneficial effect that the utility model obtains is: (1) structure is simple, (2) bottom of lower house is fixed with a backstay, the bottom of backstay is connected with spring, the end of spring is connected with a locating piece, the upper surface of described locating piece abuts on the bottom surface of driving grain, thus drive grain in the process of launching, due to firm driving grain is blocked of locating piece energy, thus can avoid driving grain to come off, guarantee rocket model energy normal transmission, (3) top of upper shell is conical, the outer wall of described lower house is evenly equipped with several balance wing, thus can guarantee that rocket model bears less air drag in the process of launching, simultaneously under the effect of balance wing, keep rocket model to be in poised state, (4) when rocket model is emitted to peak time, the gunpowder in grain is driven to be lighted by the grain in recoil grain by the first blasting fuse, gunpowder in recoil grain burns, the gas produced after its burning produces an impulsive force upwards, under the effect of impulsive force, upper shell is separated with lower house, parachute is also deviate from from lower house and is trailed, upper shell, parachute and lower house are linked together by line, and upper shell and lower house are in the process of falling, due to the existence of parachute, lapse rate can be reduced greatly, thus avoid upper shell and lower house to break in the process fallen, guarantee upper shell and the recycling of lower casing physical efficiency, thus substantially increase the utilization rate of resource.

Detailed description of the invention
As shown in Figure 1, rocket model with parachute 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 backpulsing 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, 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.
