Plate 4 is affixed.
Specifically, the both ends of flexible connecting strip 42 are connect with the upper end of the lower end of arrow 2 and clasp joint plate 4 respectively.More specifically
, flexible connecting strip 42, arrow 2 and clasp joint plate 4 are the integral structure of plastic material, and flexible connecting strip 42 is clasp joint plate 4 and arrow
One piece of region that can arbitrarily bend between first 2, thickness are less than the thickness of clasp joint plate 4 so that clasp joint plate 4 can be relative to
Arrow 2 arbitrarily rotates.There is hook portion 41, the outer wall of rocket body 1 to be equipped with the groove 12 of recess for the free end of clasp joint plate 4；When arrow 2 is pacified
Behind the top of rocket body 1, the hook portion 41 on clasp joint plate 4 can be just sticked in the groove 12 on 1 outer wall of rocket body.
Further, as shown in figures 2 and 5, as a kind of specific implementation mode of water rocket provided by the utility model, when
When the hook portion 41 is connected on the groove 12, the hook portion 41 and the angle α of 1 axis of the rocket body are not more than 90 degree.Institute
It states after hook portion 41 engages with the groove 12, hook portion 41 and the angle of 1 axis of rocket body are not more than 90 degree, are convenient for hook portion 41 from groove
Deviate from 12.
Further, as shown in figs. 1 and 3, as a kind of specific implementation mode of water rocket provided by the utility model, institute
State the arc panel that clasp joint plate 4 is evagination.
Specifically, clasp joint plate 4 is in the arc thin slice of strip, one end is flexibly connected with arrow 2, and the other end is bent to form hook
The convex side in portion 41, clasp joint plate 4 deviates from 1 evagination of the rocket body.Clasp joint plate 4 can make of elastic material, be incited somebody to action in external wind
When clasp joint plate 4 is squeezed to rocket body 1, the radian of clasp joint plate 4 can change, and the convex side of clasp joint plate 4 is made to protrude from 1 outer surface of rocket body
Height reduce, reduce the resistance of clasp joint plate 4.The clasp joint plate 4 deviates from the arc of the rocket body 1 in protrusion direction.
Further, as shown in Figures 4 and 5, as a kind of specific implementation mode of water rocket provided by the utility model, institute
It states clasp joint plate 4 and is equipped with the lug boss for protruding from 1 outer surface of the rocket body.
Specifically, lug boss protrudes from 1 outer surface of rocket body so that in extreme misery flight, lug boss is in external wind
It blows down, can recline to rocket body 1 for clasp joint plate 4 and the pressure of bigger is provided, so that hook portion 41 is engaged with groove 12 more secured.It is convex
The portion of rising can make of elastic material, and when external wind squeezes lug boss to rocket body 1, lug boss can deform, and change convex
The portion of rising protrudes from the height of 1 outer surface of rocket body, reduces the resistance of lug boss.
Further, as shown in figure 5, a kind of specific implementation mode as water rocket provided by the utility model, described
Lug boss be top connect with the clasp joint plate 4 and bottom end edge backwards the rocket body 1 direction warped wind shield 43.Specifically
, clasp joint plate 4 is strip, and upper end is connected to the tail portion of arrow 2, and lower end is free end.43 top of wind shield is connected to clasp joint
The end of the free end of plate 4,43 bottom end of wind shield deviate from 1 outer surface warped of the rocket body towards the tail end of rocket body 1 so that gear
Aerofoil 43 protrudes from 1 outer surface of rocket body.Wind shield 43 can make of elastic material, in external wind by wind shield 43 to rocket body
When 1 extruding, wind shield 43 can change, and so that the height that wind shield 43 protrudes from 1 outer surface of rocket body is reduced, reduce clasp joint plate 4
Resistance.If arrow 2 and the outstanding split after rising to peak of rocket body 1, when water rocket falls, the resistance of wind shield 43
It can ensure that hook portion 41 is detached with groove 12.
Further, as shown in figure 3, a kind of specific implementation mode as water rocket provided by the utility model, described
Rocket body 1 and the arrow 2 are connected by connecting rope 31；The both ends of the connecting rope connect with the rocket body 1 and the arrow 2 respectively
It connects, the parachute 3 is connected to the middle part of the connecting rope 31.So that in descent, rocket body 1 and arrow 2 are apart from landing
Umbrella 3 is relatively close, reduces the swing of rocket body 1 and arrow 2, keeps the landing of water rocket more stable.
Further, as shown in figs. 1 and 3, as a kind of specific implementation mode of water rocket provided by the utility model, also
Including the vertically hung scroll 5 for being set in the storage tank 11 and being connect with the connecting rope 31.The publicity of existing vertically hung scroll 5 will using balloon
Vertically hung scroll 5 rises up into the air, and such mode needs the fixed point that fixed balloon is provided on ground, prevents balloon from flying away, limits this
The application scenario of kind mode.The vertically hung scroll 5 of the utility model is in water rocket descent and parachute 3 is together from storage tank 11
In release, land slowly.Fixed point need not be set, and the scope of application is wider.
Further, as shown in figs. 1 and 4, as a kind of specific implementation mode of water rocket provided by the utility model, institute
The counterweight 22 stated the shell 21 of arrow 2 including taper and be set to inside the shell 21, the bottom of the shell 21 with it is described
The top of rocket body 1 fastens.Specifically, shell 21 is opening at its bottom of hollow taper, the top of rocket body 1 can be fastened on.
The inside at 21 tip of shell is fixed with counterweight 22 so that the weight of arrow 2 is larger, increases the weight difference of arrow 2 and rocket body 1, just
In the separation of arrow 2 and rocket body 1.
Further, as shown in figs. 1 and 4, as a kind of specific implementation mode of water rocket provided by the utility model, institute
Stating rocket body 1 has for accommodating the power sap cavity 13 of power fluid, positioned at the tail portion of the rocket body 1 and is connected to the power sap cavity 13
Jet port 14 and be connected to the empennage 15 of 1 outer wall of the rocket body.
Specifically, rocket body 1, at cylindrical shape, centre is provided with partition, the inner cavity of rocket body 1 is separated into the accommodating of open topped
The power sap cavity 13 of slot 11 and lower part, the tail portion of rocket body 1 are shrunk to the jet port 14 for being connected to the power sap cavity 13.Several tails
The wing 15 is uniformly distributed along the periphery of rocket body 1, and stabilization is played in water rocket flight course.
Further, further include being placed in institute as a kind of specific implementation mode of water rocket provided by the utility model
State the power fluid in power sap cavity 13；The power fluid is nontransparent liquid.Yellow, orange, red etc. may be used in power fluid
