Interface 101, the axis of the cylindrical interface 101 coincides with the axis of the arrow body plug-in tube 11, that is, the arrow body plug-in tube 11 passes through the cylindrical interface 101, and the cylindrical interface 101 intersects with the cylindrical through holes 124 on both sides, that is, a notch 125 communicating with the cylindrical interface 101 is formed on the inner side of the two cylindrical through holes 124; an inflatable portion 126 is also protruded on one side of the radial platform 12, and the inflatable portion 126 and the radial platform 12 are formed with the arrow body plug-in interface The inflation passage 102 communicates with the inside of the tube 11, and a one-way inflation valve (omitted in the figure, the one-way inflation valve is such as a valve core, etc.) is installed at the end of the inflation portion 126; through the laterally protruding inflation portion 126 and the one-way inflation valve, the inflation operation of the water rocket body can be carried out at the side of the launcher, which is more convenient to operate and does not occupy the space at the bottom of the launcher, so that the bottom of the launcher can be better utilized, which can be better used to simplify the launcher base and optimize the overall structure and assembly efficiency of the launcher.

[0019] Combination Figure 4-Figure 5 As shown, further: the transmitter also includes a transmitter base, the transmitter base has a base mainboard 2, a first connecting platform 21 protruding upward is formed on the base mainboard 2, a pair of first pivot seats 211 spaced opposite to each other are formed at the upper end of the first connecting platform 21, and a pair of coaxial first pivot holes 212 are opened on the first pivot seat 211; correspondingly, a first pivot portion 13 is also formed below the radial platform 12 of the transmitter body 1, and the first pivot portion 13 and the two first pivot seats 211 are adjusted and locked by screws and nuts; that is, the transmitter body 1 can be locked and installed on the transmitter base by screw nuts; Three hollow parts are formed on the base main board 2, and two of the hollow parts are opposite "L"-shaped hollow parts 201, and the other is a first hollow part 202 located between the two "L"-shaped hollow parts; a lock release component 3 is formed in the first hollow part 202, and the lock release component 3 is connected to the inner wall of the first hollow part 202 through a first connecting rib 203; a first "L"-shaped plug 41 and a second plug 42 are respectively formed in the two "L"-shaped hollow parts 201, and the first plug 41 and the second plug 42 are respectively connected to the inner wall of the "L"-shaped hollow part 201 through a second connecting rib 204, and the first plug 41 and the second plug 42 both have a cylindrical plug body 401 corresponding to the cylindrical through hole 124 on the transmitter body 1, and a cutting recess 402 opposite to the notch 125 is formed on the cylindrical plug body 401; In this way, some assembly parts of the water rocket launcher, namely the first plug strip 41, the second plug strip 42 and the lock release component 3, can be formed with the base mainboard 2 by using the same set of molds, which greatly reduces the number of molds used in the production of the water rocket launcher, thereby saving mold costs; in addition, these accessories are made integrally with the base, and do not need to be manually assembled, and can be directly sent to consumers, who can cut and assemble them by themselves, thereby preventing problems such as sending wrong parts when manually assembling parts, and also allowing consumers to have better DIY fun; Combination Figure 6 As shown, during assembly, the two cylindrical through holes 124 are used to install the first inserting strip 41 and the second inserting strip 42 respectively. Since the inserting strips are also formed with cutting recesses 402 opposite to the notch 125, when the two inserting strips are rotated to the position of the cutting recesses 402 facing the radial platform 12, the inner edges of the cutting recesses 402 will protrude into the cylindrical docking port 101, thereby clamping the flange of the bottle mouth of the arrow body, so that the arrow body of the water rocket is retained, and at this time, the exposed parts of the "L"-shaped first inserting strip 41 and the second inserting strip 42 are also perpendicular to the axis of the arrow body plug-in tube. And it is buckled by the short side lock part of the lock release component 3, and air can be inflated into the water rocket at this time; when released, the water rocket body impacts the cutting recess 402 of the insert upward under the action of the internal pressure, so that when the insert rotates until the cutting recess 402 faces the arrow body plug-in tube 11, the insert will not protrude into the cylindrical docking port 101 due to the cutting recess 402, and will not get stuck in the arrow body bottle mouth at this time, so the water rocket can be launched, and at this time, the exposed parts of the "L"-shaped first insert 41 and the second insert 42 are also parallel to the axis of the arrow body plug-in tube 11; Specifically, the lock release component 3 has an "L"-shaped sheet body 31, and second pivot seats 32 are provided on both sides of the long side of the "L"-shaped sheet body 31; one end of the radial platform 12 extends outward and is formed with a second pivot hole 127 that is axially perpendicular to the arrow body plug tube 11; when the lock release component 3 is removed from the base main board 2, a rotatable pivot is formed with the second pivot seat 32 and the second pivot hole 127 by means of screws and nuts, and the short side of the "L"-shaped sheet body 31 faces upward and can be in contact with the side of the extended connection part 123. In the locked state, the short side buckles the part outside the main body of the first insertion strip 41 and the second insertion strip 42 at the inner bottom of the short side to form a lock. When the lock release component 3 is rotated, the short side rotates axially around the second pivot hole 127 and then disengages from the first insertion strip 41 and the second insertion strip 42, so that the restriction of the two insertion strips disappears. Under the action of the internal pressure of the water rocket body, the bottle mouth flange breaks through the restriction of the insertion strips on both sides to achieve launch.

[0020] The front end insertion part of the cylindrical inserting strip body 401 of the first inserting strip 41 and the second inserting strip 42 is formed with an elastic buckle 403. When inserted into the cylindrical through hole 124, the elastic buckle 403 can shrink inward to reduce the volume. After passing through the other end of the cylindrical through hole 124, the elastic buckle 403 opens, so that the first inserting strip 41 and the second inserting strip 42 are restricted in the cylindrical through hole 124. When disassembly is required, the elastic buckle 403 can be pinched by hand to shrink it, and the inserting strip can be pulled out; the first inserting strip 41 and the second inserting strip 42 are An arc-shaped limit block 404 is also formed at the root of the cylindrical inserting strip body 401 of the first inserting strip 41 and the second inserting strip 42. Correspondingly, a limit protrusion 1241 is also formed on the inner wall at the end of the cylindrical through hole 124. The arc-shaped limit block 404 and the limit protrusion 1241 can limit the rotation angle of the first inserting strip 41 and the second inserting strip 42 to avoid unnecessary and arbitrary rotation of the first inserting strip 41 and the second inserting strip 42, and also prevent the first inserting strip 41 and the second inserting strip 42 from being inserted into each other by mistake.

[0021] A second hollow portion 205 is also formed on the base main board 2, and a rectangular latch 43 is formed in the second hollow portion 205.

The rectangular latch 43 is used to enable multiple water rocket cluster launchers to be launched by driving the pull wire to pull open the rectangular latch of the next launcher through the launch of the previous water rocket, so that the next water rocket can be launched, and cluster launches can be achieved one by one.

[0022] A rubber band slot 128 is also formed on the radial platform 12 on the side opposite to the lock release component 3, and rubber band slots 33 are also provided on both sides of the "L"-shaped sheet body 31 of the lock release component 3. A wiring hole 311 is also provided on the outside of the long side of the "L"-shaped sheet body 31 to connect a pull wire, that is, the lock release component 3 maintains elasticity with the transmitter body 1 through the rubber band to maintain the locked state. When releasing, the lock release component 3 can be pulled open by connecting the pull wire to overcome the elastic force of the rubber band.

[0023] A threading hole 14 is formed below the radial platform 12 of the launcher body 1 and at the root of the upper end of the first pivot portion 13, and a wire connection hole 34 is provided at the lower end of the lock release component 3. A brake wire can be passed through the threading hole 14, and the end of the wire is connected to the wire connection hole 34 of the lock release component 3. The brake wire can be used to pull the lock release component 3 to realize the launch control action.

[0024] A positioning tooth 131 is formed on the bottom outer wall of the first pivoting portion 13 , and correspondingly, a positioning strip 213 corresponding to the positioning tooth is provided between the first pivoting seat 211 of the first connecting platform 21 , so as to fix the launcher body and the base at a certain angle for launching. The first pivot hole 212 on the first connecting platform 21 is a longitudinally adjustable strip hole, and an angle scale line 2111 is further provided on the outer end surface of the first pivot seat 211 where the first pivot hole 212 is located.

The inner wall of the "U"-shaped slot 221 is also provided with a pair of longitudinal grooves 222; the distance between the longitudinal grooves 222 is equivalent to the flange diameter at the mouth of the mineral water bottle, and the mouth of the mineral water bottle filled with water can be clamped in the "U"-shaped slot 221 through the "U"-shaped slot 221 and the longitudinal groove 222 on its inner wall, so that the mineral water bottle is connected to the base in a lying state, and four mineral water bottles filled with water can greatly increase the stability of the base; a groove 223 is also provided in the middle of the second connecting platform 22 on one side, and the function of the groove 223 is to facilitate the passage of the wing of the water rocket when the water rocket is launched at a small angle.

[0025] The first connecting platform 21 and the second connecting platform 22 are both hollow and gradually shrink from bottom to top. In this way, multiple base mainboards 2 can be stacked up and down in sequence, thereby greatly reducing the space occupied by the packaging and saving packaging and transportation costs.

[0026] Two vertically arranged recesses 23 are provided on the base mainboard 2, for installing a small glass level respectively, so as to check whether the position of the base is flat, whether the position and angle need to be adjusted, etc. during use; the lower inner surface of the base mainboard 2 is also formed with several groups of reinforcing ribs 24 to strengthen the strength and stability of the entire mainboard, and the position of the reinforcing ribs 24 can be set as needed. The reinforcing ribs 24 located inside the first connecting platform 21 also have a limiting function after stacking, which can prevent the upper and lower bases from shaking after being stacked, making the stacking more stable; the base mainboard 2 is also formed with several connecting through holes 25, through which screws can be used to connect and assemble with the aluminum alloy track and adjust the position, so as to realize the simultaneous assembly and use of multiple transmitters, and can realize multiple different ways of assembly, which is more flexible and convenient.

[0027] Limiting support flanges 224 are formed on the outer corner side walls of the second connecting platform 22. The function of the limiting support flanges 224 is to provide limiting support for products after they are stacked, to prevent products from being squeezed against each other and bursting when too much is stacked, and to prevent products from being stacked too tightly and being difficult to remove.

[0028] The present invention has the following advantages through the above structure: First, the launcher body is integrally provided with a lateral inflation part and a built-in inflation channel, so that inflation can be performed from the side, which provides sufficient operating space and is more convenient, changing the shortcomings of the traditional inflation from the bottom, such as insufficient space and inconvenient operation; at the same time, it provides sufficient space and simplifies the design of the launcher base, which is also conducive to simplifying assembly; Secondly, when the launcher base is integrally molded, the other three launcher parts, namely the first insert, the second insert and the lock release component, can be molded at the same time, thereby reducing the number of molds required for the production of the entire launcher.
